ArtigosA conceptual framework for inventory management: Focusing on low-consumption items

Production and Inventory Management Journal, v. 49, pp.  9-26. Abstract: This article evaluates the premise of demand adherence to normal distribution in inventory management models, showing that this can lead to significant distortions, mainly to stock control of very low and low consumption items. The article thus proposes a framework to help managers determine the best stock policy to be adopted given product demand characteristics. The article also presents the use of such a framework in a case study, in an attempt to illustrate the benefits of adopting probability density functions that are more adequate to product demand characteristics, in terms of total costs of stocks.

ArtigosConsolidation effects: Assessing the impact of tail dependence on inventory pooling using copulas

International Journal of Inventory Research, v. 2, n .3, pp.174 – 188. Abstract: This paper assesses the impact of tail dependence on the consolidation effect. Based on different R packages, it was not only possible to use copulas for modelling the dependence structure between decentralised demands, but also to randomly generate and optimise different scenarios for various product characteristics, thus finding the best pooling policy: inventory centralisation, regular transshipment, or independent systems. Results suggest a different pattern for the decision-making rationale involving correlation and inventory holding costs. While independent systems and regular transshipments seem to compensate for strong upper tail dependence structures, centralisation seems to compensate for strong lower tail ones.

ArtigosCapacity issues and efficiency drivers in Brazilian bulk terminals

Brazilian Business Review, v. 11, n. 5, pp. 72–98. Abstract: This paper presents an efficiency analysis of Brazilian bulk terminals built upon the conjoint use of Data Envelopment Analysis and the bootstrapping technique. Confidence intervals and bias corrected central estimates were used as cornerstone tools, not only to test for significant differences on efficiency scores and their reciprocals, but also on returns to scale indicators provided by different DEA models. The results of the study suggest that most Brazilian bulk terminals present increasing returns-to-scale, that is, they are too small in size comparatively to the tasks performed, indicating a capacity shortfall. Results also suggest paths for improving efficiency levels in a scenario of low investments and capacity constraints: privatization and cargo specialization. A final contribution to the literature lays on the development a simple methodology to assess returns-to-scale based on bootstrap results.

ArtigosThe relationship between the logistics complexity of manufacturing companies and their supply chain management

Production, v. 24, n. 2, pp. 233-254. Abstract: This study aims to investigate whether, and the means by which, supply chain managers of large manufacturing companies adopt a context-dependent approach (also called contingency approach) in their supply chain decisions; it empirically explores the correlation between logistics complexity-related contextual conditions and supply chain management (SCM) objectives and decision areas. The study involves a comprehensive literature review, followed by an analysis of survey data (based on a sample of 108 large manufacturing companies in Brazil), using cluster analysis, factor analysis and binary logistic regression. In this study, we not only investigate the major effects of supply chain objectives and decision areas as predictors of the logistics complexity of manufacturing but also investigate their second order interactions. Statistically significant relationships were found between logistics complexity-related contextual conditions and objectives and decision areas involving the supply chain. The managers of large companies who were surveyed considered different objectives and decision areas to be critical to the achievement of supply chain excellence when their companies had different levels of logistics complexity.

ArtigosBitcoin’s price efficiency and safe haven properties during the COVID-19 pandemic A comparison

Research in International Business and Finance, v. 58. Abstract: As the COVID-19 outbreak became a global pandemic, traditional financial market indicators were significantly affected. We examine the price efficiency and net cross-correlations among Bitcoin, gold, a US dollar index, and the Morgan Stanley Capital International World Index (MSCI World) during the four months after the World Health Organization officially designated COVID-19 as a global pandemic. Using intraday data, we find that Bitcoin prices were more efficient than the US dollar and MSCI World indices. Using a detrended partial-cross-correlation analysis, our results show that net cross-correlations vary across time scales. Our results suggest that when the time scale is greater than two months, gold can be considered as a safe haven for investors holding the MSCI World and US dollar indices and when the time scale exceeds three months, Bitcoin can be considered a safe haven for the MSCI World index.

ArtigosEfficiency determinants and capacity issues in Angolan insurance companies

South African Journal of Economics, v. 82, n. 3, pp. 455-467. Abstract: This paper describes a variety of approaches used to assess the efficiency of a sample of major insurance companies in Angola between 2003 and 2012. Starting out with the bootstrapping technique, several data envelopment analysis (DEA) estimates were generated, allowing the use of confidence intervals and bias correction in central estimates to test for significant differences in efficiency levels and input-decreasing/output-increasing potentials. Previous studies have focused on the measurement and explanation of the factors affecting the performance rather than the prediction. The use of neural networks combined with DEA results as part of an attempt to produce a model for insurance companies’ performance with effective predictive ability is investigated. The findings indicate that older insurance companies with Portuguese origin tend to be more efficient. Results also suggest that opportunities for accommodating future demand appear to be scarce.

ArtigosEfficiency drivers in the Brazilian trucking industry: a longitudinal study from 2002-2010

International Journal of Physical Distribution & Logistics Management, v. 44, n. 7, pp. 540-558.  Abstract Purpose: The purpose of this paper is to investigate the issue of efficiency in the Brazilian motor carrier industry, which has undergone significant transformations since the economy deregulation in the mid-1990s. The main research objective is to determine whether or not different types of cargoes and geographic regions serviced significantly impact trucking managerial efficiency levels. Design/methodology/approach: Research objectives are accomplished by applying a two-stage data envelopment analysis model with bootstrapped estimates. Based on an unbalanced panel model, secondary data from the annual study published by Transporte Moderno (years 2002-2010) were collected and analyzed. Findings: Results support anecdotal evidence regarding a heterogeneous impact of cargo mix and route mix on efficiency levels. Research limitations/implications: A major limitation of this work concerns the fact of working with secondary data instead of primary data, especially with respect to the set of inputs and outputs used in the analysis, which may not cover all aspects relevant to building an efficiency frontier. Despite this limitation, the study has made an important contribution in its use of panel data to demonstrate the impacts of different types of cargoes and geographic regions serviced on managerial efficiency levels in the trucking industry. Practical implications: Managerial impacts in terms of mergers and acquisitions are addressed. Originality/value: The contribution of this study is twofold. On the theoretical side, a valuable scale for the measurement of managerial efficiency was built and validated, representing an index toward the most productive cargo/route mix. On the other hand, the managerial implication of this possibility of measuring the efficiency levels is that motor carriers can use it as a basis for establishing future action plans.

ArtigosInsurance companies in Mozambique: a two-stage DEA and neural networks on efficiency and capacity slacks

Applied Economics, v. 46, n. 29, pp. 3591-3600. Abstract: This article analyses the efficiency of Mozambique insurance companies using a DEA model. Two DEA models are used and a bootstrap approach adopted. Furthermore, the efficiency scores are predicted based on neural networks. The results reveal that Mozambique insurance companies’ output-increasing potentials are severely constrained, particularly in terms of the ceded reinsurance increasing potentials. Policy implications are derived.

ArtigosMeasuring efficiency improvement in Brazilian trucking: A distance friction minimization approach with fixed factors

Measurement, v. 54, pp. 166–177. Abstract: This paper investigates paths for improving efficiency in the Brazilian motor carrier industry, which has undergone significant transformations since the economy deregulation in the mid 1990s. The main research objective is to determine whether or not different types of cargoes and geographic regions serviced significantly impact trucking efficiency levels by applying a Distance Friction Minimization approach with fixed factors. Results support the evidence regarding a heterogeneous impact of cargo mix and route mix on input reducing and output increasing potentials. Managerial impacts in terms of fleet subcontracting and increased focus on specific transport demands are also addressed.

ArtigosBanking efficiency in Brazil

Journal of International Financial Markets, Institutions and Money, v. 28, pp. 54–65. Abstract: This paper analyses efficiency in Brazilian banks from 1998 to 2010 with a Bayesian dynamic frontier model. This model provides a more structural explanation for the variation in bank inefficiency than that has been presented by previous models, and also allows for cost inefficiency effects. On average, the dynamic frontier results, estimated via the Markov Chain Monte-Carlo simulation, indicate that Brazilian banks improved in terms of efficiency over time. Factors found to be important determinants of cost efficiency include public banks and foreign banks that are statistical insignificants, merger and acquisitions, big banks, deregulation and stressed banks that are statistical significant. Big bank and deregulation are the only variables that decrease costs in the Brazil market. Several Policy implications are derived.

ArtigosEfficiency determinants and capacity issues in Brazilian for-profit hospitals

Health Care Management Science, v. 17, n. 2, pp. 126–138. Abstract: This paper reports on the use of different approaches for assessing efficiency of a sample of major Brazilian for-profit hospitals. Starting out with the bootstrapping technique, several DEA estimates were generated, allowing the use of confidence intervals and bias correction in central estimates to test for significant differences in efficiency levels and input-decreasing/output-increasing potentials. The findings indicate that efficiency is mixed in Brazilian for-profit hospitals. Opportunities for accommodating future demand appear to be scarce and strongly dependent on particular conditions related to the accreditation and specialization of a given hospital.

ArtigosEthanol consumption in Brazil: Empirical facts based on persistence, seasonality and breaks

Biomass and Bioenergy, v. 63, pp. 313-330. Abstract: This paper investigates the consumption of sugar cane ethanol in Brazil for the time period from January 2000 to December 2012. We examine ethanol and gasoline consumption along with the price ratio series. Two important features of the data are analyzed, in particular, its degree of persistence and the seasonality. The results show that the two series of consumption are fractionally integrated with orders of integration smaller than 1 implying that shocks in the series will disappear in the long run. On the other hand, the price ratio series displays an order of integration higher than 1 implying lack of mean reversion behavior. This suggests that strong policy measures must be adopted on prices in the event of shocks since they do not recover by themselves in the long run.

ArtigosTax-related aspects of logistics network planning: a case study in the Brazilian petrochemical industry

International Journal of Logistics Research and Applications, v. 17, n. 2, pp. 114-135. Abstract: This study investigates the logistics network planning in a major Brazilian petrochemical company, taking into consideration the impact of tax-related costs, in addition to transportation and inventory costs. A Mixed Integer Nonlinear Programming model that considers the most relevant costs involved in the network planning process in Brazil was developed and subsequently applied to a case study of a large Brazilian petrochemical company. Our results support anecdotal reports regarding Brazilian companies intensely using ‘product tourism’ to take advantage of different interstate tax rates. Product tourism occurs when a logistically unnecessary flow of goods is established to a lower tax jurisdiction (with a corresponding increase in transportation costs) so that the company obtains a reduction in the amount of the taxes due.

ArtigosTwo-stage DEA: an application to major Brazilian banks

Expert Systems with Applications, v. 41, n. 5, pp. 2337-2344. Abstract: Although banking has been widely studied using standard DEA (Data Envelopment Analysis) models and its variations, these models do not in fact account for the internal structure relative to measures characterizing banking operations performance. In this paper, efficiency in Brazilian banking is measured using a two-stage process. In the first stage, called cost efficiency, number of branches and employees are used to attain a certain level of administrative and personnel expenses per year. In the second stage, called productive efficiency, these expenses allow the consecution of two important net outputs: equity and permanent assets. The network-DEA centralized efficiency model is adopted here to optimize both stages simultaneously. Results indicate that Brazilian banks are heterogeneous, with some focusing on cost efficiency and others on productive efficiency. Furthermore, cost efficiency is explained by M&A and size, while productive efficiency is explained by M&A and public status. Policy implications for the Brazilian banking sector are also derived.

ArtigosO método dos itinerários: uma contribuição metodológica das ciências sociais à pesquisa de consumo em gestão

Revista Brasileira de Marketing –ReMark, v. 13, n. 2, pp. 74-83. Resumo: A escolha do consumidor tem sido um dos principais interesses dos estudos em comportamento do consumidor nos últimos cinquenta anos. Ao longo do tempo, entretanto, o foco desta pesquisa tem se ampliado a fim de incluir não somente o momento da compra, mas, também, gradualmente, uma reflexão sobre o processo de decisão do consumidor, no que tange à seleção, consumo e descarte de produtos e serviços. Recentemente, pesquisadores treinados em áreas como antropologia e sociologia têm contribuído com perspectivas que encaram o processo de escolha como um fenômeno cultural e social. Este artigo apresenta o Método dos Itinerários: uma abordagem de pesquisa originalmente inspirada nos estudos antropológicos de consumo. O método pode contribuir para a pesquisa de comportamento do consumidor, no campo de administração, ao viabilizar a investigação do processo de consumo – seleção, consume e descarte – dentro de uma perspectiva sistêmica, que permite expandir a compreensão da temática da escolha do consumidor, tomando a cultura como elemento central de análise. O método é descrito, juntamente com a apresentação de suas premissas, etapas operacionais, e exemplos concretos de pesquisas sobre consumo.

ArtigosMeanings of consumption and abandonment: understanding smoking cessation symbolism

BAR – Brazilian Administration Review, v. 11, n. 2, pp. 210-227. Abstract: In consumption studies, very little attention has been focused on investigating abandonment and, more specifically, its symbolic dimension. The present study aims to investigate how meanings are created and negotiated through the abandonment of cigarettes. This study used a qualitative methodology to collect and analyze the data generated by one-on-one semi-structured in-depth interviews with 15 Brazilian ex-smokers. Results suggest that abandonment of cigarettes can be offered as a connection, gift, or sacrifice that makes relations special and even magical. As regards abandonment, the present study evidences the interactions and movements of positive and negative meanings related to the consumption and non-consumption of a category. The study proposes a framework that highlights the cooling, decontamination, reinforcement and defensive symbolical movements, thus constructing a tool for analyzing abandonment, offering possible paths of intervention for organizations that are interested in this issue.

ArtigosPerceptions of unfairness in price increases: an experimental study

Revista de Administração, v. 49, n. 3, pp. 566-577. Abstract: This experimental study investigates antecedents and consequences of perceptions of price unfairness in a price increase situation. The proposed theoretical model states that consumer dependence on the service provider as well as the relevance the consumer attributes to the service (for the consumer’s life) will affect his/her degree of (a) unfairness price perception, (b) anger, and (c) intention to complain and retaliate. The results support all the hypotheses specified in the model. The findings not only indicate that some situations of unfairness price perception lead to stronger emotions and more dramatic reactions from consumers, but also allow us to predict which situations of perceived unfairness offer greater risks and have greater potential for conflict.

ArtigosIt doesn’t hurt to ask: Assessing default effects in a Brazilian gas station

International Business Research, v. 7, n. 6, pp. 61-66. Abstract: When an option is set as the default and as a result people are more likely to choose it, we call it a default effect. In this research we investigated whether drivers were more likely to choose a more expensive type of fuel if it was set as the default option by a mere suggestion from the gas station attendant. In the first study, we collected data showing that drivers did not believe they could be affected by default options. The second study, however, refuted these findings: we conducted a field experiment in which a trivial question asked by the gas station attendant, whose effect was the creation of a default option, led drivers to purchase a product they would not otherwise have considered. We thus provide evidence that default effects might be even more pervasive in real situations with real consumers than what one would expect from controlled laboratory experiments.

Casos de EnsinoO processo de internacionalização de empresas de comércio eletrônico sob o olhar comportamental: estudo longitudinal dos casos MercadoLibre e eBay

Revista Alcance, v. 21, n. 1, pp. 126-151. Resumo: Foram estudados de forma qualitativa os casos das empresas de comércio eletrônico MercadoLibre, criada na Argentina em 1999, e eBay, concebida nos Estados Unidos em 1995, desde sua fundação até 2012. Os casos foram analisados utilizando arcabouço da literatura sobre internacionalização de empresas, contemplando tendências globais e fatores do país, da indústria, da empresa e do empreendedor. Foi constatada interação entre as quatro principais abordagens comportamentais sobre o processo de internacionalização: Modelo de Uppsala, perspectiva de networks, empreendedorismo internacional e Born Globals, sendo que nenhuma delas, de forma isolada, seria capaz de explicar os processos observados. Foi também encontrada forte relação entre a importância estratégica do país escolhido e o modo de entrada ou de operação seguido. Países com maior importância estratégica passavam a ser operados a partir de subsidiárias locais, enquanto países de menor importância possuíam operação remota.

ArtigosRepresentações e estereótipos das pessoas com deficiência como consumidoras: o drama dos personagens com deficiência em telenovelas brasileiras

Organizações & Sociedade, v. 21, n. 70, pp. 387-404. Resumo: A despeito de serem importantes meios de comunicação da cultura, dos valores e das perspectivas vigentes em uma sociedade, os textos culturais configuram possibilidades pouco exploradas em pesquisas acerca do comportamento do consumidor com deficiência. No Brasil, novelas televisivas parecem ser textos culturais adequados para esses estudos, tendo em vista a importância apresentada pelas telenovelas como programas transclassistas de abrangência nacional. Definiu-se como objetivo do estudo discutir as representações e os estereótipos das pessoas com deficiência (doravante PcD) como consumidoras apresentados em telenovelas brasileiras. Para atingir o objetivo foram analisadas cenas de 22 telenovelas brasileiras que mostram personagens com deficiência em situações de consumo. Os resultados do estudo alertam para a necessidade de que empresas, instituições públicas e a sociedade em geral revejam a forma como lidam com esses consumidores quase invisíveis que, muitas vezes, não são considerados como potenciais clientes e são excluídos de ações de políticas públicas.

ArtigosLá vai o consumidor pela ponta esquerda! Um estudo sobre consumo adolescente de futebol na cidade do Rio de Janeiro

Revista ADM.MADE, v. 18, n. 1, pp. 79-104. Resumo: O esporte se tornou uma atividade importante no mundo atual e constituiu um mercado próprio bastante complexo. O presente trabalho procura oferecer contribuições aos estudos de consumo do esporte, mais especificamente o consumo do futebol por adolescentes. Essa opção se mostra adequada, uma vez que o futebol é um dos esportes mais populares no mundo e que o estudo de experiências vivenciadas na adolescência ajuda a entender não apenas o comportamento de consumo dos jovens, mas também o desenvolvimento do comportamento dos adultos. Dada a perspectiva exploratória desse estudo, foi adotada abordagem qualitativa e foram realizadas entrevistas em profundidade com 15 adolescentes moradores da zona sul da cidade do Rio de Janeiro. Os dados qualitativos foram analisados com base em análise de conteúdo. Ao fim, foi possível levantar aspectos relacionados a experiências de consumos associadas ao futebol (torcer e praticar); ao consumo da camisa de time de futebol; e aos ídolos do futebol. Ficou claro que o movimento de globalização dos mercados e a tecnologia disponível de forma mais ampla modificaram a forma com que jovens assistem e praticam o futebol. Além disso, a camisa do uniforme do time de futebol passa a ser consumida de três formas, tendo uso esportivo, social ou como peça de coleção.

ArtigosEconomia, marketing e indivíduos de baixa renda: O interesse após uma história de indiferença

Revista de Ciências da Administração, v. 16, n. 39, pp. 49-64. Resumo: Durante a construção da área de marketing, estudiosos utilizaram conceitos e teorias econômicas como base para o desenvolvimento de seus próprios conceitos e teorias. Essa similaridade é percebida no tratamento que marketing deu aos indivíduos de baixa renda e sua relação com o consumo em seus primeiros estudos. Assim como os economistas, os pesquisadores em marketing descreviam esses indivíduos como dependentes da sociedade e dos governos para melhorarem suas vidas. Essa visão muda quando Prahalad defende uma nova perspectiva, na qual indivíduos de baixa renda são vistos como consumidores, com desejos de consumir produtos de diversas naturezas. O objetivo do presente ensaio, portanto, é analisar os caminhos percorridos na economia e em dois momentos em marketing sobre o indivíduo de baixa renda. Discute, inicialmente, o pensamento econômico sobre esses indivíduos, para, em seguida, apresentar duas perspectivas de marketing sobre o segmento.

ArtigosInnovation in hospitals and the service-dominant logic

Revista de Gestão em Sistemas de Saúde – RGSS, v. 3, n. 1, pp. 14-26. Abstract: The development of the research on innovation in services has resulted in three approaches: technologist, service-based, and integrative. Each has a specific focus on the role of technology and the endogenous or exogenous character of innovations in services. The path chosen by state of the art research in the area has been to consolidate an integrative perspective. New research has used a service-dominant logic which allows an integrated view of economic activities based on the logic of value linked to services. This approach has raised the possibility of expanding the integrative approach, focusing on how innovations change the value proposition of a particular service through a new technology, by innovation in methods or in the service relationship. The aim of the present article is to develop this perspective using empirical research into hospital services. These activities, due to their complexity and strong interaction with different economic and social actors, bring to the fore many of the fundamental theoretical questions surrounding the debate on innovation in services, and provide a new perspective on hospital management. Based on semi-structured interviews, case studies on innovations in hospitals in Brazil and France were conducted from 2006 to 2010. The innovations studied involve new types of relationship with users, adoption of new technologies and innovations stemming from research and development. These case studies identified types, actors, and outcomes of innovation in order to develop an approach based on a broader integrative perspective, involving the analysis of characteristics and the service-dominant logic.

ArtigosTecnologias móveis e inovação em serviços: um estudo em empresas francesas

Revista ADM.MADE, v. 18, n. 2, pp. 49-74. Resumo: As tecnologias móveis possibilitam novas formas de configuração do trabalho e de processos organizacionais, criando oportunidades para modelos inovadores de gestão. Este artigo apresenta os resultados de pesquisa realizada com o objetivo de investigar as relações entre o uso de tecnologias móveis de informação e comunicação (MICTs) e as inovações em serviços. Foi testado modelo teórico que supõe que as MICTs influenciam positivamente a inovação de procedimentos e de mercado, de forma direta, e também por meio do desenvolvimento de capacidades internas e de mercado. O referencial teórico foi baseado principalmente na Teoria da Capacidade de Absorção (ACAP), a partir da análise das capacidades dinâmicas de conhecimento e de integração social. A fase empírica foi baseada em um survey, respondido por 51 gestores de empresas de serviços na França. Os dados coletados foram analisados usando a técnica de Partial Least Square. Os principais resultados desta investigação sugerem que, em alguns casos, as MICTs afetam diretamente a inovação. As tecnologias móveis podem também influenciar essa variável por meio do desenvolvimento de capacidades internas e de mercado. Isso vai variar de acordo com o tipo de tecnologia utilizada.

ArtigosA relação entre inovação e desempenho internacional de atividades de serviços em firmas francesas

INMR – Innovation & Management Review, v. 11, n. 3, pp. 227-254. Resumo: Partindo do pressuposto que a internacionalização pode ser um fator determinante para que as empresas, no setor de serviço, percebam a inovação como primordial para o desenvolvimento, este artigo tem como objetivo determinar como se dá a relação entre a inovação de serviços e o desempenho internacional de empresas de serviços. Com base em marco teórico desenvolvido a partir de teorias de internacionalização e inovação de serviços, foi construído um modelo sobre as relações entre estes fatores, incluindo as seguintes variáveis: desempenho internacional, inovação de serviço, experiência internacional, competência internacional, capacidade organizacional, capacidade relacional e capacidade da empresa de utilizar as novas tecnologias da informação e da comunicação. O questionário utilizado para a coleta dos dados foi construído a partir dos indicadores desses fatores e avaliado em uma escala Likert de 5 itens. A amostra, retirada de banco de dados francês Altares e após várias seleções, foi constituída por 51 empresas. O método utilizado para tratamento dos dados, o Partial Least Square (PLS), revelou uma relação entre inovação e o desempenho internacional das empresas estudadas.

ArtigosCan R&D be identified and measured in services? Empirical evidence from university hospitals

Science and Public Policy, v. 41, n. 6, pp. 793–808. Abstract: This paper proposes an in-depth analysis of some of the constraints on case studies conducted at French university hospital services, aiming to better understand R&D in their services. We begin with an analysis of the intangibility of inputs (knowledge and information) and outputs that confirms the difficulty in recognizing innovations based on the social sciences and humanities. This empirical study verified that there was a diversity of actors who contributed to the generation and increase of the stock of knowledge. Concerning R&D funding, it is noted that R&D in services is not always planned in terms of a formal project. Finally, one could argue that advances in research allow the recognition of different relationships at the same time as the boundaries of R&D in services are expanded, allowing a better measurement of its results.

ArtigosRegulação de acesso à internação em UTI: análise pela teoria da inovação em serviços

Revista de Administração Hospitalar e Inovação em Saúde, v. 13, n. 1, pp. 174-189. Resumo: Partindo da abordagem integradora da teoria da inovação em serviços, o processo de inovação foi estudado, considerando a regulação de internação em unidades de terapia intensiva (RIUTI) no Distrito Federal como um feixe de cinco serviços elementares constitutivos. Os modos de inovação, as lógicas de serviço e as operações de serviço envolvidas na RIUTI foram descritos nos cinco serviços constitutivos. Baseando-se no conceito de inovação como variações nos componentes de vetores de características dos produtos dos serviços, foi possível identificar a variedade dos processos de inovação nos diferentes serviços e estabelecimentos. O setor público apresentou-se como protagonista do processo de inovação e indutor de inovações no setor privado, necessárias para viabilizar a inserção desses estabelecimentos na RIUTI. Foram constatadas melhorias expressivas na equidade de acesso à internação em unidade de terapia intensiva no Distrito Federal. Permanecem obstáculos estruturais e de gestão que impedem avanços adicionais na integralidade da atenção em saúde. Entre as limitações locais, destacam-se as deficiências no sistema de contrarreferência e na oferta de serviços de média complexidade.

ArtigosExecução de estratégia sob o prisma de mudança organizacional

Revista de Administração FACES Journal, v. 13, n. 1, pp. 124-141. Resumo: O artigo propõe que se considere o processo de execução de estratégia como um processo de mudança organizacional. Para tanto, uma revisão da literatura sobre implementação e uma categorização dos estudos são realizadas como forma de mapear o atual estágio do conhecimento. Em seguida, duas abordagens de aproximação são desenvolvidas com apoio de literatura sobre mudança organizacional, sendo a primeira focada em explorar o fenômeno como um processo e, a segunda, voltada para identificar lacunas no desenvolvimento de conteúdo sobre o tema. Finalmente, são apresentadas algumas implicações para a teoria e a prática, bem como propostas de pesquisa futura.

ArtigosNeutralizing unethical negotiating tactics: An empirical investigation of approach selection and effectiveness

Negotiation Journal, v. 30, n. 1, pp. 23-48. Abstract: Negotiation is integral to business success, and information is the lifeblood of the negotiation process. When invalid information is disseminated via manipulation or deceit, one or more parties can suffer. Nonetheless, many studies have shown that the use of questionable or unethical tactics is commonplace. This article reports on a study of twelve behaviors that can neutralize a counterpart’s tendencies to employ questionable or unethical tactics, improving the chances for an integrative (win–win) outcome. The results suggest that while nearly two thirds of participants employed neutralizing behaviors, they used many of these behaviors later in the negotiation process than anticipated and simultaneously alongside questionable or unethical tactics. While we found some evidence that the twelve neutralizing behaviors were viewed differently from questionable or unethical tactics, the expected attenuating effects were not found. The implications of these findings, including opportunities for future research, are discussed.

ArtigosFamily informed consent to organ donation. who performs better: OPOs, in-hospital coordinators or ICU professionals?

Transplantation Proceedings, v. 46, n. 6, pp. 1672–1673. Abstract: Successful organ donation in countries adopting informed consent legislation depends on adequate interviewing of potential donors’ families. As the number of both referral and effective donors in Brazil increases, health care managers argue whether educational efforts should be directed toward training in-hospital coordinators (IHC)–based on the “Spanish model”–or on the creation of extra-hospital-based professionals (Organ Procurement Organizations [OPOs], the “American model”). Meanwhile, many potential donor families are still approached by intensive care unit (ICU) professionals not trained in donation interviews. The aim of our study was to compare performances in obtaining informed consent from potential donors’ families, according to the type of health care professional conducting the interviews: OPO, IHC, or ICU staff. In this retrospective 2-year study performed in Rio de Janeiro, Brazil, we observed an increase in referrals (285 to 411) and consent rates (48.1% to 55.7%). Each year, OPO professionals conducted most family interviews (58.6% and 60.4%, respectively) and obtained better consent rates (63.5% and 64.5%, respectively), when compared to IHC (41.8% and 53.7%, respectively) or untrained ICU professionals (22.1% and 13.4%, respectively). Our results show that adequate professional training is necessary for obtaining family consent for organ donation. Both established international policies for organ procurement and donation, namely the “Spanish model” with its IHCs or the “American model” of extra-hospital OPOs, may equally achieve this task. However, family interviews performed by untrained ICU professionals result in low donation rates and should be discouraged.

ArtigosRobust pair-copula based forecasts of realized volatility

Applied Stochastic Models in Business and Industry, v. 30, n. 2, pp. 183-199. Abstract: A useful application for copula functions is modeling the dynamics in the conditional moments of a time series. Using copulas, one can go beyond the traditional linear ARMA (p,q) modeling, which is solely based on the behavior of the autocorrelation function, and capture the entire dependence structure linking consecutive observations. This type of serial dependence is best represented by a canonical vine decomposition, and we illustrate this idea in the context of emerging stock markets, modeling linear and nonlinear temporal dependences of Brazilian series of realized volatilities. However, the analysis of intraday data collected from e-markets poses some specific challenges. The large amount of real-time information calls for heavy data manipulation, which may result in gross errors. Atypical points in high-frequency intraday transaction prices may contaminate the series of daily realized volatilities, thus affecting classical statistical inference and leading to poor predictions. Therefore, in this paper, we propose to robustly estimate pair-copula models using the weighted minimum distance and the weighted maximum likelihood estimates (WMLE). The excellent performance of these robust estimates for pair-copula models are assessed through a comprehensive set of simulations, from which the WMLE emerged as the best option for members of the elliptical copula family. We evaluate and compare alternative volatility forecasts and show that the robustly estimated canonical vine-based forecasts outperform the competitors.

ArtigosMétricas, mídias e anunciantes: discutindo a relação

Revista Brasileira de Marketing –ReMark, v. 13, n. 4, pp. 78-93. Resumo: O estudo procura compreender como anunciantes brasileiros vêm se adaptando às novas mídias e suas métricas de atenção. Foram realizadas entrevistas em profundidade com anunciantes em 2009 e 2011. Em 2009, novas mídias e suas métricas eram percebidas como inovações que aumentariam a eficiência das campanhas. Em 2011 esta percepção se mostrou prejudicada: a profusão de métricas das novas mídias, antes percebida como um diferencial, passa a comprometer sua facilidade de uso e sua adoção. Dentre seus achados, e estudo aponta para uma oportunidade para grupos de comunicação se deslocarem da orientação ao produto para uma orientação ao cliente, desenvolvendo métricas simples e integradas para anunciantes.

ArtigosFrom print to screen: changes and challenges facing the Brazilian publishing industry

Revista de Administração, v. 49, n. 3, pp. 491-505. Abstract: The publishing industry is at a turning point. Facing the first major disruptive innovation in five centuries, its long-established structure and business model are at stake. Building on literature based on the pitfalls for incumbents, we interviewed key executives from the major publishers in Brazil to understand their perspective. We find that not only are they facing those pitfalls, but we also propose a new one, The Industry View Trap, concerning challenges created by convergence, the difficulty to deal with changes in the ecosystem and the fact that the very definition of the industry you’re part of might have changed.

ArtigosO impacto das mídias digitais na comunicação organizacional das empresas

Future Studies Research Journal: Trends and Strategies, v. 6, n. 1, pp. 53-82. Resumo: O presente estudo investiga os impactos na Estratégia e nos processos de Comunicação Organizacional das empresas brasileiras provocados pela adoção das chamadas Mídias Sociais Digitais. Para esse estudo exploratório foram entrevistados executivos de Comunicação Organizacional de empresas de grande porte de diversos setores. As onze entrevistas em profundidade tiveram como base um roteiro semi-estruturado e foram processadas por meio da Análise de Conteúdo, com a identificação de categorias, por meio do software NVIVO. Os resultados revelaram a incipiente adoção das Mídias Sociais Digitais na Estratégia de Comunicação Organizacional. Ela se mostra como um processo em evolução e que representa um desafio para as organizações. Como fatores inibidores da adoção foram citados o desconhecimento sobre a dinâmica das plataformas, a ausência de benchmarks e a carência de profissionais especializados. Embora declarem que as Mídias Sociais Digitais são um fenômeno irreversível, os executivos receiam à potencial amplificação de crises de Comunicação decorrentes de possíveis “erros” cometidos na Web.

ArtigosElectronic media use: Towards an integrative model

Journal of Global Information Management (JGIM), v. 22, n. 1. Abstract: The objective of the study is to propose and test a model to understand the factors that impact the use of electronic media in Brazil. A survey was conducted, capturing perceptions about five electronic media – Broadcast TV, Pay-TV, Internet, Mobile Phones and Game Consoles. A sample of 1000 cases was collected by personal interviews in six cities and analyzed using SEM. Attitude is influenced by Image, Entertainment and Content, followed by Communication and Habit. The model explained 80% of Attitude and 90% of Satisfaction. Attitude is a strong predictor of Satisfaction. Attention is explained by Entertainment and Satisfaction.

ArtigosUm estudo sobre o gerenciamento da informação contábil pelos municípios fluminenses para alcance do piso constitucional de aplicação em saúde

Pensar Contábil, v. 16, n. 59, pp. 4-9. Resumo: O ano de 2000 marcou o início de uma nova fase da responsabilidade fiscal na contabilidade do setor público brasileiro. Além da festejada publicação da Lei de Responsabilidade Fiscal, entrou em vigor no mesmo ano a chamada “Emenda da Saúde”, que determinou o limite percentual mínimo das receitas a serem aplicados em ações e serviços públicos de saúde. No entanto, este dispositivo constitucional foi omisso quanto às rubricas orçamentárias a serem consideradas para que os respectivos cálculos fossem efetuados. A falta de regulamentação criteriosa sobre o que deve ou não ser contabilizado como despesa de saúde possibilitava aos gestores que se utilizassem indevidamente da prática de gerenciamento das informações contábeis (GIC), a fim de adequarem-se aos parâmetros de gastos exigidos pela Constituição Federal. Somente a regulamentação trazida pela Lei Complementar no 141, de 13 de janeiro de 2012, deu fim à possibilidade de interpretações distintas. Este artigo teve como objetivo verificar se há evidência de GIC por parte dos municípios fluminenses, utilizando-se de manobras contábeis envolvendo despesas inscritas em Restos a Pagar. Analisando a relação entre a inscrição e o cancelamento destas despesas, bem como observando e dando tratamento estatístico aos dados financeiros municipais disponibilizados pelo Tesouro Nacional, concluímos não haver evidências de GIC envolvendo cancelamento de empenhos inscritos em Restos a Pagar. Isto porque 79 dos 81 municípios fluminenses analisados cumprem com facilidade o limite mínimo de despesas com saúde, sendo o montante de empenhos cancelados insuficiente para mudar esta condição.

ArtigosPoder explicativo de variáveis contábeis no preço das ações das companhias elétricas em ambiente de IFRS

Revista Ambiente Contábil, v. 6, n. 1, pp. 219-235. Resumo: Este artigo tem como objetivo analisar comparativamente a capacidade explicativa de componentes da informação contábil em IFRS e BRGAAP, mais especificamente Lucro Líquido Por Ação (LLPA) e Patrimônio Líquido Por Ação (PLPA), de 24 companhias do setor de energia elétrica, nos exercícios de 2009 e 2010, em relação ao preço das ações na BM&FBOVESPA. A escolha de companhias que atuam no mercado brasileiro de energia elétrica, para realização desta pesquisa, foi motivada pelos seguintes fatores: relevância econômica do setor e que a contabilidade deste seguimento vem sofrendo com a adoção do padrão IFRS no Brasil, em especial pela adoção da ICPC 01 (IFRIC 12). Nesse sentido, foram empregados testes de análise de regressão múltipla para: comparação do R2 ajustado (Adjusted R Squared), comparação dos critérios informacionais de Akaike e Schwarz e análise de coeficientes padronizados. Os resultados da regressão mostraram que as variáveis contábeis LLPA e PLPA apresentam maior capacidade conjunta de explicação com a adoção do IFRS. Além disso, o PLPA passou a apresentar maior poder explicativo, enquanto o LLPA teve seu poder de explicação reduzido com a adoção do IFRS. Estas diferenças mostram que o preço das ações passou a ser melhor explicado com os ajustes oriundos da ICPC 01 (IFRIC 12), principalmente no PL.

ArtigosDeterminantes do nível de divulgação das recomendações do Pilar 3 do Acordo de Basiléia 2 nas demonstrações financeiras de Instituições Bancárias que atuam no Brasil

Brazilian Business Review, v. 11, n. 1, pp. 26-50. Resumo: O artigo objetiva identificar os determinantes do nível de evidenciação, no que tange às informações recomendas pelo Pilar 3 do Acordo de Basileia 2, para as 100 maiores instituições bancárias atuantes no Brasil em 2010. Para tanto, analisa-se o nível de divulgação de cada instituição pesquisada e só então buscam-se os determinantes deste nível de evidenciação. Nesse sentido, parte-se de cinco hipóteses, baseadas nas seguintes variáveis: tamanho, nacionalidade, concentração de votos, tipo de capital e índice de Basileia. Para testar estas hipóteses, utilizou-se de utilizaram-se testes de diferença de médias e de análise de regressão múltipla, considerando o nível de significância de 10%. Observa-se que as variáveis: tamanho, índice de Basileia e tipo de capital são significativas, ou seja, são capazes de explicar o nível de evidenciação das informações analisadas. Por fim, ressalta-se que as varáveis concentração de votos e nacionalidade não foram significativas.

ArtigosThe human factor: a successful acquisition in Brazil

Management Research Review, v. 37, n. 3, pp. 261-287. Abstract Purpose: The purpose of this case study was to identify how the human factor influenced the 2010 acquisition of company X’s cement factory, located in town C in the Brazilian State of Goiás, by the multinational company A. Design/methodology/approach: Seventeen in-depth interviews were conducted with employees who participated of the acquisition process: 15 with professionals with leadership roles at the factory, the others with company A corporate executives. The data collected were qualitatively treated using discourse analysis to unveil the perceptions of the interviewees. Findings: The discussion involved topics such as: resistance to change, uncertainty, employees’ expectations and commitment, stress, employee turnover and retention. The present study contextualizes existing theoretical approaches, and its main conclusion confirms that not all M&A processes cause permanent negative impacts that lead to the failure of the acquisition or are perceived as a strong and lasting source of uncertainty by the employees of the involved companies. On the contrary, depending mainly on the perception, employees have of their working conditions at the time the acquisition process takes place; on the strategic relevance of the acquisition to the acquiring company (its motivation); on how the process is managed by the executives of the acquiring company; on the communication strategy employed by the acquiring company, as well as on the understanding of the cultural setting; and on the acquiring company having an organizational culture with policies that value employees, the community and sustainability; this change can be perceived as favourable by employees thus fostering a successful acculturation and outcome. Finally, this study is considered valuable to researchers and practitioners as it indicates that although the human factor is not considered a priority in most M&A processes, it is clearly paramount to its success or failure, specially in lock-in situations when the acquiring and acquired companies have complementary and reciprocal interdependencies. Research limitations/implications: In spite of the contributions of this research to the field of studies on M&A, the authors have to acknowledge limitations, such us: as town C was a small factory at the time of the acquisition, there were only 17 interviewees, which does not constitute a large sample. The possibility of a certain amount of unavoidable subjectivity in both the interviewees when relating their experience and the interviewer when analyzing the collected data. As stated before, being a case study, results cannot be generalized. Originality/value: This research adds to the actual state of the art on M&A signalling that there should be a match between the strategies selected by the executives of the acquiring company and the specificities of the human factor and its cultural environment. Specifically, this case study contributes to theory advancement by proposing the concept of lock-in in M&A.

ArtigosMelhores práticas em inovação: Uma pesquisa em empresas do setor de TI

Revista de Administração da UFSM, v. 8, n. 4, pp. 685-705. Resumo: O objetivo desta pesquisa foi avaliar até que ponto a adoção, em maior ou menor grau, de práticas de gestão de inovação preconizadas pelo modelo de gestão de inovação de Hull e Tidd (2003) explicaria, juntamente com o contexto, o desempenho, tanto em desenvolvimento de inovações em serviços quanto em prestação de serviços, de 36 empresas de serviços de Tecnologia da Informação (TI) do estado do Rio de Janeiro. A pesquisa identificou que o componente do modelo que discriminou mais indicadores de desempenho em desenvolvimento de inovações em serviços foi o contexto (ambiente) em que as empresas estão inseridas. O resultado da regressão logística efetuada indicou que a capacidade de integração recíproca e a presença formalizada de um setor de desenvolvimento na estrutura organizacional da empresa, dimensão interna do contexto, foram determinantes para as empresas da amostra estarem acima ou abaixo da média em termos de desempenho em desenvolvimento de inovações em serviços. Percebeu-se, ainda, com uma correlação moderada a um nível de significância de 0,01, que um bom desempenho em inovação de serviços implica um bom desempenho na prestação dos serviços novos ou melhorados.

ArtigosEstudo sobre a relação entre o resseguro, gestão dos índices regulatórios e a redução dos tributos em seguradoras no Brasil

Contabilidad y Negocios, v. 10, n. 20, pp. 41-58. Resumo: A recente entrada de novos resseguradores, além do tradicional/estatal/monopolista, deu nova cara ao mercado de seguros nacional, modificando de modo profundo as características das operações de resseguros contratadas pelas seguradoras. A relação do nível de resseguro com índices de solvência, de tributos e com determinantes deste, foi alvo de pesquisas internacionais e nacionais, sendo as últimas apenas no período pré-abertura do mercado (até 2007). Neste contexto, este estudo analisa, por meio de modelo de regressão linear com dados pooled, se o uso do resseguro pelas seguradoras brasileiras, no período de 2011 a 2013, foi influenciado pelos níveis de solvência, tributos, rentabilidade e tamanho. Em consonância com as pesquisas internacionais, não foi encontrada significância estatística para as variáveis de solvência. O determinante «Tamanho» indicou que seguradoras menores possuem maior aversão ao risco e, assim, níveis mais elevados de resseguro. A proxy de tributos apresentou significância positiva, sugerindo que as seguradoras nacionais utilizam o resseguro como ferramenta de gestão tributária. A proxy de rentabilidade mostrou-se eficaz para explicar o relacionamento com o nível de resseguro utilizado pelas seguradoras nacionais, indicando que as seguradoras nacionais mais rentáveis tendem a investir mais no gerenciamento de seus riscos fazendo maior uso do resseguro em suas operações que as menos rentáveis. O presente estudo encontrou indícios de que o resseguro é utilizado pelas seguradoras brasileiras, não só como uma ferramenta de gestão de riscos, mas também na gestão tributária e de resultados.

ArtigosComunidades de marca de Sports Fantasy Games: Identificação, engajamento, intenção de continuidade e valor da marca do patrocinador

Revista Brasileira de Marketing – ReMark, v. 14, n. 1, pp. 33-48. Resumo: O estudo investigou em que medida a identificação e engajamento de membros da comunidade de marca de um Fantasy Sport Game (FSG) influenciam a intenção de continuidade na comunidade e o valor da marca do patrocinador do FSG. A perspectiva teórica da CCT – Consumer Culture Theory (Arnould & Thompson, 2005) serviu como referencial teórico do estudo, mais especificamente, o conjunto de estudos sobre as Comunidades de Marca. O modelo de Influência Social das Comunidades de Marca (Algesheimer, Dholakia, & Herrmann, 2005) foi usado como base para o desenvolvimento do modelo conceitual do presente estudo, que focou jogadores do Cartola FC, principal FSG brasileiro de futebol. Foi coletada uma amostra não probabilística por julgamento por meio de uma web survey junto aos membros da fanpage oficial do FSG Cartola FC, que resultou em 3.710 questionários válidos. Verificou-se a confiabilidade e a validade convergente, discriminante e nomológica dos construtos. As hipóteses do estudo foram testadas por meio de modelagem de equações estruturais. Foram empiricamente suportadas cinco das seis hipóteses. Os resultados sugerem que o valor da marca do patrocinador de um FSG é influenciada positivamente pelo engajamento e intenção de continuidade dos membros da comunidade.

ArtigosThe effect of simultaneous sponsorship of rival football teams

BAR – Brazilian Administration Review, v. 12, n. 1, pp. 63-87. Abstract: The present study investigated the impact of team identification and team-sponsor fit on the sponsor’s brand equity. The study’s main theoretical references are (a) the Social Identity Theory (Tajfel & Turner, 1979); (b) the Schema Theory (Singer, 1968) and (c) the Associative Network Theories (Collins & Loftus, 1975), both about the functioning of the human memory; and (d) customer-based brand equity (Keller, 1993). Research was conducted in Porto Alegre, RS, a Brazilian city where rival football (soccer) teams Grêmio and Internacional share their main sponsors, Banrisul and Unimed, since 2001 and 2002, respectively, a rare context that was previously studied only once before (Davies, Veloutsou, & Costa, 2006). The valid sample comprised 2,000 fans of both teams. The sample was non-probabilistic with equal gender and team quotas. Data analysis was performed using Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA); and the reliability, convergent, discriminant and nomological validity of the constructs were verified. To test the substantive hypotheses, Structural Equation Modeling (SEM) using the ADF technique was applied. The empirical results suggest that, in the studied context, the sponsor’s brand equity is more influenced by team-sponsor fit than by team identification, which is different from a non-rivalry sponsorship context.

ArtigosFranchising as a means of achieving internationalization: Research propositions from a multiple case study of Brazilian fashion retailers

CONTEXTUS Revista Contemporânea de Economia e Gestão, v. 13, n.  3, pp. 57-80. Abstract: According to Brazilian Franchising Association, the number of Brazilian franchises has grown 300%in the last ten years, but only 3% of Brazilian franchises operate in foreign markets, so the opportunity to internationalization   is   strong. Aiming   to   get   a   better understanding of possible distinctive features of Brazilian retail internationalization, this paper explores the determinants of franchising as the choice of internationalization entry mode by Brazilian’s firms in the fashion apparel sector. The multiple-case study was the approach used.  The study resulted   in eleven research propositions. Results show that government or trade organizations support, geographic distance, political and economic risk may not be determinant to internationalization. However cultural proximity and relationship with local partners can be determinant to internationalization. Moreover, brands that cater to a very specific segment and that their value proposition is closely linked to intangible factors may face problems in expanding to culturally distant international environments.

ArtigosBrazilian initial public offerings, underwriting, and premium corporate governance segments listing

Corporate Ownership and Control, v. 13, n.  1, pp. 1410-1418. Abstract: We examined 89 offers in the most recent Brazilian IPO wave between 2004 and 2007, all listed in premium segments of the exchange that demand better corporate governance practices. Two non-US underwriters dominated the market, often acting as co-leaders and rarely as second-tier underwriters. Twenty-eight percent of issuers received pre-IPO loans from underwriters, which may constitute a conflict of interest. Syndicate membership increased with offer size, suggesting that distribution risk was relevant. Underwriter compensation increased with offer size, but percentage fees suggested scale effects. There was no evidence in favor of the relevance of underwriter reputation, certification, and price discovery roles. The study brings a portrait of underwriter relationships in this unique period of the Brazilian capital market

The average CGI score of 5.8 (out of 10.0) in 2013 may be considered lowand points to the need for further improvement.  Moreover, firms score very low intheethics andconflicts of interest aspects of the CGI, whencompared toitsdisclosure, board composition andfunctioning, and shareholders rightscomponents. The very small number of firms that ban loans to related partiesand that facilitate participation in the shareholder   meetings   is   a   concern. The decreasein   the use   of   control enhancement   mechanisms, such   as   non-voting   shares   and   indirect   control structures,was  a  remarkable  achievement.  Even so,shareholder  agreements  are increasingly  used  as  instruments  tointerfere  with  director  independence  andleverage the controlling bloc power.

ArtigosFacing the regulators: noncompliance with detailed mandatory compensation disclosure in Brazil

Emerging Markets Finance and Trade, v. 51, n. 2, pp. S47-S61. Abstract: A preliminary court injunction based on alleged personal security risks gave Brazilian public companies the option of noncompliance with new executive and director compensation disclosure rules. We find that noncompliance is possibly motivated by agency conflicts and not by crime rates in the state where the company is headquartered. Noncompliers tend to present lower corporate governance (CG) quality, higher ownership concentration, larger total assets, and less profitability. State- and foreign-owned companies are significantly less likely noncompliers. Shareholders correctly anticipated that lower CG quality firms were more likely noncompliers but may have been negatively surprised when some higher CG quality firms did not comply.

ArtigosExchange-Traded Private Equity and Venture Capital Companies and Macroeconomic Factors in Brazil

Latin American Business Review, v. 16, n. 4, pp. 255-277. Abstract: This article indirectly investigates whether private equity and venture capital (PEVC) constitute an asset class different from publicly traded stocks with respect to the influence of macroeconomic risk factors. It uses a portfolio of three Brazilian exchange-traded asset management companies with PEVC funds to represent this asset class in vector autoregression models. The portfolio of PEVC stocks failed to present an attractive historical return and behaved similarly to portfolios of large and small stocks with respect to their risk exposure profile in relation to these factors. This limited sample does not suggest that these PEVC managing companies are a different class of assets, but does not reject the view of regulators and practitioners that PEVC funds are a different asset class.

ArtigosCarteiras igualmente ponderadas com poucas ações e o pequeno investidor

Revista de Administração Contemporânea, v. 19, n. 5, pp. 544-564. Resumo: Este artigo analisa carteiras igualmente ponderadas (1/N) com foco no investidor sem sofisticação, com carteiras de pequenas de ações. A quantidade de ações incluídas nas carteiras 1/N foi de 6 a 16, e o rebalanceamento, feito apenas três vezes ao ano. O período de análise incluiu retornos diários e mensais, entre 1998 e 2011. O desempenho das carteiras 1/N foi comparado ao de fundos de investimento em ações (FIAs), a uma carteira de mínima variância global com limite de 10% sobre os pesos positivos (MVP 10%) e ao Ibovespa. As comparações empregaram testes não paramétricos, medidas de retorno ajustado ao risco e consideram custos de transação. Os resultados, por sua vez, indicam que os FIAs selecionados apresentam desempenho, na melhor das hipóteses, equivalente ao das carteiras 1/N, apesar de apresentarem desvio padrão menor. Não se constatou retorno mediano das carteiras 1/N significativamente diferente do da Ibovespa e do da MVP 10%. O critério de seleção das ações, segundo ordenamento pelo Índice de Sharpe do período anterior, é relevante, mas o rebalanceamento pode ser feito menos de três vezes ao ano. As carteiras 1/N são, portanto, uma alternativa atraente em relação aos FIAs para investidores com carteiras pequenas de ações, apesar de seus custos de transação poderem ultrapassar 400 pontos base por ano.

ArtigosA joint experimental analysis of investor behavior in IPO pricing methods

RAE-Revista de Administração de Empresas, v. 55, n. 1, pp.14-25. Abstract: This article jointly examines the differences of laboratory versions of the Dutch clock open auction, a sealed-bid auction to represent book building, and a two-stage sealed bid auction to proxy for the “competitive IPO”, a recent innovation used in a few European equity initial public offerings. We investigate pricing, seller allocation, and buyer welfare allocation efficiency and conclude that the book building emulation seems to be as price efficient as the Dutch auction, even after investor learning, whereas the competitive IPO is not price efficient, regardless of learning. The competitive IPO is the most seller allocative efficient method because it maximizes offer proceeds. The Dutch auction emerges as the most buyer welfare allocative efficient method. Underwriters are probably seeking pricing efficiency rather than seller or buyer welfare allocative efficiency and their discretionary pricing and allocation must be important since book building is prominent worldwide.

Resumo: A proposta deste artigo é mapear e analisar, a partir de uma perspectiva histórica, as políticas governamentais de apoio à internacionalização de empresas brasileiras, com foco direcionado para o setor da construção civil. Em outros termos, objetiva-se pensar os negócios internacionais não como sendo uma atividade de interesse exclusivo das empresas, mas, sobretudo como um fator de grande relevância para os objetivos estratégicos de desenvolvimento dos países. O referencial teórico que deu suporte para análise do caso foi um framework integrativo entre o Paradigma Eclético de Dunning e a teoria institucionalista. O método de pesquisa aplicado foi o estudo de caso, realizado a partir da triangulação na coleta e análise dos dados empíricos, visando conjugar dois níveis de análise: o Estado e a empresa. A conclusão deste estudo foi que a internacionalização das maiores empresas brasileiras desse ramo de atividade, a consolidação delas no mercado externo e a distribuição geopolítica de seus investimentos tiveram e ainda têm grande influência do papel histórico desempenhado pelo governo nesse processo.

ArtigosEmpreendedorismo internacional e Effectuation: O caso do Café Yaguara Ecológico

 Internext, v. 10, n. 3, pp. 15–30. Resumo: O objetivo deste estudo é investigar o papel do empreendedor e as características do processo de internacionalização de uma pequena empresa brasileira produtora de café, Yaguara Ecológico, à luz de diferentes abordagens teóricas. Foi realizada uma revisão da literatura com atenção especial às teorias de Empreendedorismo Internacional e Effectuation. O presente trabalho trata do fenômeno da International New Venture (OVIATT; McDOUGALL, 1994) e, com intuito de compreender a relevância dos empreendedores no processo de internacionalização da empresa, foi eleita a teoria Effectuation que oferece alternativas para descrever como estes pensam e se comportam ao iniciar um novo empreendimento (PERRY et al., 2012). O método para a pesquisa foi o estudo de caso único e entrevistas em profundidade foram realizadas com gestores da empresa. Os resultados sugerem que as teorias ofereceram explicações para os movimentos de internacionalização da empresa, entretanto, algumas características dessa trajetória não aderiram às proposições teóricas.

ArtigosDiasporic and transnational internationalization: The case of Brazilian martial arts

Brazilian Administration Review, v. 12, n. 4, pp. 403-420. Abstract: Brazilian diasporas overseas has received little academic interest. Nevertheless, estimates suggest that around three million Brazilians currently live in other countries. The present study looks at a specific type of diaspora: small entrepreneurs from the Brazilian martial arts sector. The study adopts the case study method of research. The unit of analysis is comprised by the martial arts (capoeira and Brazilian jiu-jitsu). Data analysis used secondary and primary data from interviews. Cross-case analysis searched for similarities and differences in the internationalization processes of the two martial arts, using several analytical devices, such as chronologies, timelines, matrices, and pattern matching analysis. Evidences suggest that the concept of diasporic internationalization fits better capoeira than Brazilian jiu-jitsu. However, Brazilian jiu-jitsu shows an initial combination of diasporic and transnational characteristics, but more recently became fully transnational. Brazilian jiu-jitsu became a truly global business, formally organized and professionally managed. Capoeira, however, is still seen as non-commercial and as the preservation and practice of an ancient art. Such ethos, combined with the origin of its members in lower economic classes and their restricted access to capital turns internationalization into an often less profitable activity.

Journal of Business Research, v. 68, n. 2, pp. 241-254. Abstract: The case describes the internationalization process of emerging markets multinational enterprises in other emerging markets. Marcopolo, the largest manufacturer of bus bodies in Brazil and one of the largest in the world, started several joint ventures to manufacture bus bodies. After years of consistent headway in a globalization strategy, including several success stories, the company was facing hard times along several fronts. The case specifically examines the experiences in Russia, India, and Egypt, their inception, and the subsequent events until the beginning of 2011. The case can be used in conjunction with case (A) International Expansion of Marcopolo (A): Adventures in China—or separately.

ArtigosSlacks determinants in Brazilian railways: a distance friction minimization approach with fixed factors

Applied Economics, v. 47, n. 47, pp. 5103-5120. Abstract: This study investigates the drivers for output-increasing/input-saving potentials in the Brazilian railway industry, which has undergone significant transformations since its privatization in the mid-1990s. The main research objective is to determine whether or not different types of cargoes and geographic regions serviced present a significant impact on railway slacks by applying a distance friction minimization (DFM) approach with fixed factors. Based on a balanced panel model, secondary data from the period 2004 to 2012 were collected and analysed. Results support anecdotal evidence regarding a heterogeneous impact of types of cargo and geographic location on input-reducing and output-increasing potentials, besides network length and average speed. Policy implications for railway authorities are also addressed by focusing on the specifics of each railway operator.

ArtigosPublic-private partnerships and scale efficiency in Brazilian ports: Evidence from two-stage DEA analysis

Socio-Economic Planning Sciences, v. 51, pp. 13-22. Abstract: This paper assesses the impacts of public-private partnerships on major Brazilian public ports. It is proposed that these kinds of arrangements with private terminal operators could help achieving higher levels of scale efficiency by enhancing coordination processes, providing more adequate information technologies, and higher connectivity with other transportation modes. Methodology relies on factor extraction of inputs/outputs as a first step to compute DEA efficiency estimates, followed by truncated bootstrapped regression analysis to test different contextual variables. Results indicate a strong positive impact of public-private partnerships on port scale efficiency, corroborating their impacts in relation to the most productive scale size.

ArtigosOptimization of contribution margins in food services by modeling independent component demand

Revista Colombiana de Estadística, v. 38, n. 1, pp. 1-30. Abstract: We propose a methodology useful for food services, allowing contribution margins to be optimized. This is based on statistical tools, inventory models and financial indicators. To reduce the gap between theory and practice, we apply this methodology to the case study of a Chilean company to show its potential. We conduct a real-world demand data analysis for perishable and non-perishable products in the company’s inventory assortment. Then, we use suitable inventory models to optimize the associated costs. We compare the proposed optimized system with the non-optimized system currently employed by the company, using financial indicators.

ArtigosMutual fund flows: An analysis of the main macroeconomic factors

Revista Gestão da Produção Operações e Sistemas, v. 10, n. 1, pp. 1-11. Abstract: This paper analyzes whether some macroeconomic factors (country risk, IBrX volatility and Interbank Certificate of Deposit) are related to mutual fund flows for the period between January 2005 and August 2014. In order to investigate whether the flow series behaved differently during this period, the Chow test was conducted for September 2008 (the month in which the Lehman Brothers investment bank collapsed). The regressions were performed and the parameters were estimated through the OLS method for both periods, the first running from January 2005 to August 2008 and the second from September 2008 to August 2014. For the period between January 2005 and August 2008, all the variables, except for the Interbank Certificate of Deposit, proved significant, at a significance level of 10%. For the subsequent period, none of the variables proved significant and the R² was very low, which may merely indicate that investors failed to analyze the main macroeconomic variables for mutual fund allocations or redemptions and simply considered other aspects, such as manager performance.

ArtigosIncluding carbon emissions in the planning of logistic networks: a Brazilian case

International Journal of Shipping and Transport Logistics, v. 7, n. 6, pp. 655 – 675. Abstract: The issue of sustainability has gained increasing importance in the agenda of government leaders and business managers alike, all over the world. Companies have come to realise that on top of being beneficial for the planet, strategies for the reduction of greenhouse gas emissions and sustainability policies represent important opportunities for businesses growth. Many such strategies are related to the business supply chain, where most decisions that impact emissions and sustainability are made. Examples of such decisions can be found in supply chain logistic network design and management: facility location, definition of transportation modes, and distribution policies, including which facilities should serve what markets. In this work, a nonlinear mathematical model to support the planning of more sustainable logistic networks was developed using a plausible hypothetical logistic network located in Brazil as a case. One aspect of the developed model that sets it apart from others in the current literature is that in addition to traditional logistic costs, carbon emission costs resulting from transportation activities along the supply chain were also taken into account in the analysis. Sensitivity analyses were conducted by using a computer simulation aimed at evaluating road and rail transportation modes, in terms of the impact that each has on the cost optimisation of the network configuration, especially in regard to the total cost of emissions and stocks held in the chain to ensure a desired level of customer service.

ArtigosFinancial distress drivers in Brazilian banks: A dynamic slacks approach

European Journal of Operational Research, v. 240, n. 1, pp. 258-268. Abstract: This study applies the Dynamic Slacks Based Model (DSBM) developed by Tone and Tsutsui (2010) in order to assess the evolution of input saving/output increasing potentials in major Brazilian Banks from 1996 to 2011. We propose that these potentials or slacks can be used as proxies for an eventual financial distress situation in the future. The main research objective is to determine whether or not different characteristics of bank type – related to ownership, size, and merger and acquisition processes – are significantly related to inefficiency levels and, by extension, to an eventual financial distress situation, since higher inefficiency levels also imply lower input saving/output decreasing potentials. Based on a balanced panel model, secondary data from Economatica were collected and analyzed. Results indicate higher inefficiency levels and slacks in small public and national banks. Policy implications are also addressed.

ArtigosExploring the potential use of the Birnbaum-Saunders distribution in inventory management

Mathematical Problems in Engineering, v. 15. Abstract: Choosing the suitable demand distribution during lead-time is an important issue in inventory models. Much research has explored the advantage of following a distributional assumption different from the normality. The Birnbaum-Saunders (BS) distribution is a probabilistic model that has its genesis in engineering but is also being widely applied to other fields including business, industry, and management. We conduct numeric experiments using the R statistical software to assess the adequacy of the BS distribution against the normal and gamma distributions in light of the traditional lot size-reorder point inventory model, known as (, ). The BS distribution is well-known to be robust to extreme values; indeed, results indicate that it is a more adequate assumption under higher values of the lead-time demand coefficient of variation, thus outperforming the gamma and the normal assumptions.

ArtigosEnergy efficiency of selected OECD countries: A slacks based model with undesirable outputs

Energy Economics, v. 51, pp. 45-53. Abstract: This paper presents an efficiency assessment of selected OECD countries using a Slacks Based Model with undesirable or bad outputs (SBM-Undesirable). In this research, SBM-Undesirable is used first in a two-stage approach to assess the relative efficiency of OECD countries using the most frequent indicators adopted by the literature on energy efficiency. Besides, in the second stage, GLMM–MCMC methods are combined with SBM-Undesirable results as part of an attempt to produce a model for energy performance with effective predictive ability. The results reveal different impacts of contextual variables, such as economic blocks and capital–labor ratio, on energy efficiency levels.

ArtigosAre there multiple bubbles in the ethanol–gasoline price ratio of Brazil?

Renewable and Sustainable Energy Reviews, v. 52, pp. 19-23. Abstract: This paper tests for the existence of bubbles in the ethanol–gasoline price ratio in Brazil from 2000 to 2012 using right-tailed ADF tests. Results suggest the existence of two bubbles: one which has already burst (during the re-election of President Lula); and one which has been ongoing since 2010, thus corroborating empirical and anecdotal evidence in the Brazilian sugarcane industry. Freezing gasoline prices not only depressed ethanol prices but also depressed investments in new sugarcane crops and distillation plants.

ArtigosAn empirical analysis of freight transport traffic modes in Brazil, 1996–2012

Transportation Planning and Technology, v. 38, n. 3, pp. 305-319. Abstract: This paper analyses the performance of freight transportation modes in Brazil – namely air, water, rail and road – from February 1996 to August 2012 by investigating their long memory properties using fractional integration and autoregressive models on monthly tonnage data. Two important features are analysed: the degree of dependence of transportation traffic across time and its seasonal structure over the period. Furthermore, the stability of parameters across the sample period is investigated, incorporating potential structural breaks in the data, which describe discontinuity in freight transportation traffic. Some policy implications are derived.

ArtigosAn analysis of Asian airlines efficiency with two-stage TOPSIS and MCMC generalized linear mixed models

International Journal of Production Economics, v. 169, pp. 110-126. Abstract: This study reports on the performance assessment of the Asian airlines using TOPSIS – a multi-criteria decision making technique – as the cornerstone method to compute efficiency scores. Subsequently, and observing indicators frequently found in literature, TOPSIS results on efficiency levels are combined with GLMM-MCMC methods to assess the impact of contextual variables on performance. The results reveal significant impacts of cost structure, ownership type, market positioning, and mileage program offered on efficiency levels. Findings also suggest that gains in efficiency level were stagnated over the period analyzed, implying the inexistence of a learning curve.

ArtigosAn analysis of African airlines efficiency with two-stage TOPSIS and neural networks

Journal of Air Transport Management, v. 44–45, pp. 90-102. Abstract: This paper presents an efficiency assessment of African airlines, using the TOPSIS – Technique for Order Preference by Similarity to the Ideal Solution. TOPSIS is a multi-criteria decision making technique, which similar to DEA (Data Envelopment Analysis), ranks a finite set of units based on the minimisation of distance from an ideal point, and the maximisation of distance from an anti-ideal point. In this research, TOPSIS is used first in a two-stage approach, in order to assess the relative efficiency of African airlines using the most frequent indicators adopted by the literature on airlines. During the second stage, neural networks are combined with TOPSIS results, as part of an attempt to produce a model for airline performance which has effective predictive ability. The results reveal that network size-related variables – economies of scope, are the most important variables for explaining levels of efficiency in the African airline industry, although the impact of fleet mix and public ownership cannot be neglected.

ArtigosAnálise da inovação no processo de convergência midiática: O caso da indústria de jornais brasileira

Revista Gestão e Desenvolvimento, v. 12, n. 1. Resumo: As mídias digitais são descritas por diversos autores como uma grave ameaça ao jornal, que vem, desde o advento e a disseminação da internet em larga escala, perdendo clientes em ambos os lados da plataforma: leitores e anunciantes. Este estudo tem por objetivo explorar como a inovação está impactando a indústria de jornal, investigando possíveis focos de inovação. Foram realizadas 37 entrevistas em profundidade com gestores de anunciantes de grande e pequeno porte de diversos setores e de agências de publicidade. Os resultados sugerem que não são os anunciantes ou as agências de propaganda os impulsionadores da inovação no ecossistema das mídias, especialmente devido ao lock-in implementado pelas mídias tradicionais. Parecem ser os leitores, que fragmentam sua atenção e migram para novas mídias, os motores da inovação. Entretanto, as inovações podem representar oportunidades para veículos que se aproximarem do oferecimento de soluções totais para seus clientes, sejam eles consumidores ou anunciantes.

ArtigosConstituição de uma comunidade virtual de marca no lançamento de novo produto

RAC. Revista de Administração Contemporânea, v. 19, pp. 117-136. Resumo: A presente pesquisa analisa o processo de formação de uma comunidade em torno de uma marca antes do seu efetivo lançamento no mercado. Para isso, utilizou-se o método netnográfico para investigar uma comunidade automotiva criada meses antes da chegada do automóvel às ruas. O trabalho sugere a busca por informações e o desejo de influenciar o desenho da nova oferta, como fatores a mobilizar os consumidores em torno da comunidade. O envolvimento com a categoria, o posicionamento aspiracional da marca corporativa e a expectativa de mudanças a partir desse lançamento também se mostraram como aspectos relevantes na constituição do grupo. O trabalho sugere uma tipologia de membros a partir de duas dimensões: a informação sobre a categoria e a experiência de uso com a marca/modelo em questão. A tipologia distingue novatos (baixa informação e baixa experiência), teóricos (alta informação e baixa experiência), pragmáticos (baixa informação e alta experiência) e experts (alta informação e alta experiência) e evidencia lógicas que hierarquizam as interações entre os membros, ajudando a explicar as dinâmicas e o processo de evolução da comunidade.

ArtigosPrecedents and consequences of price unfairness perceptions: an exploratory study in the Brazilian context

Revista de Administração, v. 49, n. 3, pp. 566-579. Abstract: This experimental study investigates antecedents and consequences of perceptions of price unfairness in a price increase situation. The proposed theoretical model states that consumer dependence on the service provider as well as the relevance the consumer attributes to the service (for the consumer’s life) will affect his/her degree of (a) unfairness price perception, (b) anger, and (c) intention to complain and retaliate. The results support all the hypotheses specified in the model. The findings not only indicate that some situations of unfairness price perception lead to stronger emotions and more dramatic reactions from consumers, but also allow us to predict which situations of perceived unfairness offer greater risks and have greater potential for conflict.

ArtigosUma proposta de arcabouço teórico para análise do comportamento dos investimentos diretos estrangeiros em economias emergentes

Revista Ciências Administrativas, v. 21, n. 2, pp. 499-550. Resumo: O objetivo deste ensaio teórico foi identificar determinantes dos investimentos diretos outward de firmas com sede em países considerados emergentes. Foi feita análise crítica da base de dados da UNCTAD e revisão da teoria do Investment Development Path (Teoria IDP), proporcionando a integração dos resultados de estudos empíricos relacionados a investimentos diretos com a literatura mais pertinente. A conclusão da pesquisa permitiu a sugestão de um arcabouço teórico contendo determinantes que podem empurrar ou puxar investimentos outward a partir de economias emergentes. Tal arcabouço visa ampliar a contribuição da Teoria IDP, sugerindo determinantes complementares ao PIB per capita. Com relação ao estado da prática, o arcabouço pode servir de orientação para estratégias de internacionalização de firmas de economias emergentes, assim como para o direcionamento de políticas governamentais de tais países.

ArtigosTurismo voluntário e o bem-estar do consumidor na pesquisa transformativa do consumo

Revista Ciências Administrativas, v. 21, n. 2, pp. 531-553. Resumo: A pesquisa transformativa do consumo é uma vertente de estudos preocupada em contribuir para o bem-estar do consumidor, tendo em vista o impacto gerado pelas práticas de mercado. Ao mesmo tempo, foi possível localizar um referencial também recente sobre turismo voluntário, que envolve lazer e trabalho em prol de auxiliar comunidades em situação de fragilidade, e tem mobilizado esforços de estudos acadêmicos e de indivíduos engajados em questões relacionadas à redução da pobreza e da desigualdade social. Este artigo tem como objetivo analisar o fenômeno do turismo voluntário pelas lentes da abordagem transformativa, destacando como esta abordagem pode contribuir para o desenvolvimento da pesquisa sobre o tema, e como o fenômeno do turismo voluntário pode oferecer oportunidades de teorização para a pesquisa transformativa. Foram identificadas e articuladas três oportunidades de construção de teorias: teorização em nível metodológico, multicultural e em serviços transformativos. Nas considerações finais, são apresentados caminhos futuros de pesquisa no contexto brasileiro.

ArtigosTranscendendo a abordagem individual do consumo: Uma investigação dos significados do automóvel pela perspectiva das famílias

Brazilian Business Review, v. 12, n. 2, pp. 91-114. Resumo: Na área de comportamento do consumidor, as famílias são identificadas como grupo de referência fundamental no processo de consumo. Historicamente, pesquisas envolvendo decisões de compra têm, em sua maioria, foco em decisões individuais sem contemplar as dinâmicas de interações dentro desse importante grupo. Utilizando-se de abordagem qualitativa, baseada no método dos itinerários, o presente trabalho investiga como os significados relacionados à compra de um automóvel ajudam a moldar relações dentro da família, quando se investiga o consumo. A partir de entrevistas e de observações realizadas com diversos integrantes de dez famílias paulistanas, o presente trabalho evidencia os automóveis como artefatos capazes de demarcar valores e hierarquias familiares, funcionando ainda como importante ferramenta “educacional” e de transição para vida adulta dos filhos.

ArtigosQueremos mobilidade! lógicas de consumo associadas à experiência com o primeiro automóvel

Revista de Administração da Unimep, v. 13, n. 1. Resumo: O consumo da população de renda mais baixa tem se intensificado nos últimos anos e a participação desse grupo de consumidores no mercado não tem se limitado apenas à categoria de produtos simples e essenciais. A opção por formas de pagamento mais acessíveis, tais como cartões de crédito, com suas opções de parcelamento, propiciou o acesso a produtos e serviços outrora disponíveis apenas às classes mais abastadas, como viagens, aparelhos tecnológicos como celulares e computadores e, principalmente, automóveis. Dessa forma, alguns autores passaram a defender a concepção de que os limites da base da pirâmide social, já não eram suficientes para definir o grupo de compradores que entram com mais força no mercado de bens e serviços de consumo, assim, outras denominações e contornos sociais foram atribuídos a esses indivíduos, como a caracterização de “classe média emergente”. Dessa forma, guiado pelos questionamentos: quais os principais significados associados à experiência de compra do primeiro carro? Que lógicas de consumo sobre esse grupo de consumidores da cidade de Teresina podem ser identificadas a partir de suas ações no mercado de automóveis? Este estudo buscou identificar e compreender significados e práticas construídos no processo de consumo do primeiro automóvel de um grupo de consumidores da cidade de Teresina. Nesta pesquisa qualitativa, exploratória, com suporte no paradigma interpretativista e no campo da Consumer Culture Theory (CCT), que utilizou como instrumento de coleta de dados um roteiro de entrevistas semiestruturado, foram realizadas entrevistas em profundidade com 18 consumidores da classe média emergente de Teresina. Para analisar as falas dos sujeitos adotou-se a proposta metodológica de Spiggle (1994), assim, todas as entrevistas foram lidas, por diversas vezes, na busca por aspectos convergentes e divergentes que permitissem a formulação de categorias de análise. Posteriormente, as categorias encontradas foram comparadas com o corpo teórico existente sobre a temática para validar os achados e permitir posteriormente, a formulação de teorias. A interpretação dos relatos sugere que esse grupo de consumidores inicia sua experiência no mercado de automóveis a partir de significados e práticas associados a aspectos utilitários dessa categoria de produtos que diferem daqueles apontados em outros estudos que estavam focados em consumidores de mais alta renda. Dessa forma, os relatos não destacaram os valores simbólicos e subjetivos que aparecem como os mais importantes na literatura consultada. Os achados desse estudo exploratório falam de liberdade, conforto e conquista associados à mobilidade urbana diferindo, assim, em sua construção, daqueles significados simbólicos encontrados em outros estudos sobre o comportamento do consumidor de automóveis.

ArtigosUrban governance and the systems approaches to health-environment co-benefits in cities

Caderno de Saúde Pública, v. 31, suppl 1. Abstract: The term “co-benefits” refers to positive outcomes accruing from a policy beyond the intended outcome, often or usually in other sectors. In the urban context, policies implemented in particular sectors (such as transport, energy or waste) often generate multiple co-benefits in other areas. Such benefits may be related to the reduction of local or global environmental impacts and also extend into the area of public health. A key to identifying and realising co-benefits is the adoption of systems approaches to understand inter-sectoral linkages and, in particular, the translation of this understanding to improved sector-specific and city governance. This paper reviews a range of policies which can yield health and climate co-benefits across different urban sectors and illustrates, through a series of cases, how taking a systems approach can lead to innovations in urban governance which aid the development of healthy and sustainable cities.

Artigos“Humanized Robots”: A Proposition of Categories to Understand Virtual Influencers

Australasian Journal of Information Systems, v. 25. Abstract: Worldwide investments in influencer marketing are growing and could reach US$ 101 billion in 2020. But how can the brands shield themselves from scandals and other limitations of human influencers? The solution for many companies has involved robots. Virtual influencers (VI) are virtual robots that can emulate human appearance and behaviour and have become a trend in marketing. This study analyses how non-human influencers affect marketing communication by adopting two methods that are unpublished in the investigation of this phenomenon: a systematic literature review and netnography in conjunction with in-depth interviews with specialists resulting in the study identifying five categories (two of which are unpublished and unexplored in the literature) that can facilitate management decisions and also future studies around VIs: anthropomorphism/humanization, attractiveness, authenticity, scalability, and controllability. This study also identified more convergences than divergences between the virtual and the real and between humans and non-humans, generating challenges, opportunities, and guidelines for future research and for assisting management in making decisions concerning digital marketing.

ArtigosFundos de previdência privada: passividade a preços de fundos ativos
Revista Contabilidade & Finanças – USP, v. 29, n. 76, pp. 148-163. Resumo: De 2005 a 2015, o total de ativos geridos por fundos de previdência privada aberta no Brasil mais do que sextuplicou, com o Plano Gerador de Benefícios Livres (PGBL) e o Vida Gerador de Benefícios Livres (VGBL) representando 90% desses ativos. Entretanto, as instituições de previdência privada têm como característica a cobrança de elevadas taxas de administração, fi cando, assim, com boa parte dos benefícios oferecidos pelo governo como incentivo para os investimentos nessa modalidade. Altas taxas de administração são justifi cáveis quando há uma gestão ativa desses fundos, gerando, em tese, uma performance superior: este estudo indica que não é isso que ocorre nesse segmento de mercado. Problemas semelhantes têm sido enfrentados em outros países, como Reino Unido, Dinamarca e Suécia, nos quais se abriu investigação a respeito de fundos que cobram altas taxas de administração por uma gestão ativa enquanto proporcionam, na realidade, uma gestão que pode ser considerada passiva. Isso demonstra o tamanho e a relevância desse problema, que foi levantado e abordado por este estudo. Para tanto, recorreu-se à análise dinâmica de estilos, via janelas móveis, seguida da análise via fi ltro de Kalman em fundos das cinco principais instituições de previdência privada do Brasil. A partir da análise da evolução das exposições desses fundos às diferentes classes de ativos e dos R2 gerados, encontraram-se indícios de passividade, principalmente nos fundos compostos com renda variável. Tais fundos são justamente os que deveriam ter gestão mais ativa, pois cobram as maiores taxas de administração. Este artigo também demonstra que é possível construir uma carteira passiva, com estilo muito semelhante e retornos sem diferenças estatisticamente signifi cativas, mas com taxa de administração mais baixa (e alinhada com fundos passivos).

ArtigosMists vapors and other illusory volatilities of electronic cigarettes

Cadernos de Saúde Pública, v. 33,  Suppl 3. Abstract: In this article, we analyze the discourse of electronic cigarette suppliers directed at convincing potential users (smokers, former smokers or never smokers) to acquire and use the new product. This is a qualitative, descriptive and exploratory study on sellers’ discourse found in eight on-line sales websites which, between 2011 and 2013, had the highest search frequencies. The websites were identified through Google Trends based on the number of accesses and search frequencies related to electronic cigarettes. Our methodological reference was dialectical-hermeneutics. We categorized the empirical material within the “understanding/interpretation” scheme within four broad meanings: appropriation of the anti-smoking discourse; comparison between conventional and electronic cigarettes; appeal to the trustworthiness of science and projection of e-cigarettes’ image. The analysis of these meanings configured the argumentative elements of the marketing discourse used by electronic cigarette makers and suppliers.

ArtigosInformation technology governance adoption: understanding its expectations through the lens of organizational citizenship

International Journal of IT/Business Alignment and Governance (IJITBAG), v. 7, n. 2. Abstract: IT Governance (ITG) can support the organizational decision-making on its IT initiatives, increasing the alignment IT/business. The goal is to understand how ITG influences the behavior of individuals within organizations. Organizational Citizenship Behavior (OCB) concept was selected to analyze individuals’ voluntary commitment within an organization that is not part of their contractual tasks. The premise is that ITG influences organizational citizenship behavior such as job satisfaction and rewards perception. The research was conducted through a focus group made up of the members of an IT State Governance Committee in Brazil and semi structured interviews with IT managers from the state departments. Questions based on OCB were discussed in order to understand the behavioral changes expectations along the ITG mechanisms adoption. The preliminary results showed that citizenship behavior could improve because of the ITG process. Based on the results, a preliminary conceptual model was proposed.

ArtigosThe Role of the Private Sector in Global Climate and Energy Governance

Journal of Business Ethics, v. 130, pp. 375–387. Abstract: The private sector plays an active role in implementation of mechanisms concerning the mitigation of climate change. In spite of that, the corporate actors play a limited direct role in international arenas when it comes to negotiating the design of climate and energy regime. The climate and energy governance in the United Nations system remains mostly state-centric, but the active participation of corporate actors in negotiation of climate and energy regimes is essential to increase the effectiveness of their governance. Business is not just a subject of a regulatory climate and energy imposed by the state; rather, business is an intrinsic part of the fabric of climate and energy governance, as “rule-maker,” particularly in the many voluntary regimes. However, the architecture in place should guarantee that the private sector does not highjack the decisions and its positions are balanced by other non-governmental actors in the process. This article analyzes the role that the private sector can play in the global climate and energy governance. The private sector does not only play a “rule taker” role in the climate change and energy regime. Indeed, they are not passive observers as they influence through indirect means. The results suggest that the private sector is able to play a key role in global climate and energy governance based on the principle of multi-stakeholder participation in global decision-making, but the architecture should be able to balance the goods and bads of private direct influence in international regimes.

ArtigosSustainable production and consumption of palm oil in Indonesia: What can stakeholder perceptions offer to the debate?

Sustainable Production and Consumption, v. 4, pp. 16-35. Abstract: Meeting the global demand for palm oil poses great sustainability challenges. Indonesia is experiencing one of the largest oil palm expansions worldwide. Important socioeconomic and environmental impacts of the palm oil sector remain unsolved including conflicts over land tenure, loss of biodiversity, air pollution and emission of greenhouse gases. The Roundtable on Sustainable Palm Oil (RSPO) is a multi-stakeholder alliance promoting best practices along palm oil supply chains. However, the RSPO’s potential to truly enhance the sustainability of palm oil production and consumption has been questioned. The different stakeholder groups that comprise the RSPO often hold different agendas and perspectives, posing a barrier for enhancing the sustainability of the sector. Moreover, RSPO stakeholders’ perceptions may not be necessarily attuned to local realities and sensibilities in Indonesia. This paper, (a) provides a rapid appraisal of the perceptions on the barriers for improving palm oil sustainability as held by the main RSPO stakeholder groups and (b) contrasts them with the views of local communities in oil palm expansion areas. Our results suggest that RSPO stakeholders’ perceptions about enhancing palm oil sustainability are overall highly divergent. However there seemed to be an underlying common optimism among some RSPO stakeholders and local communities about the feasibility of a technical fix. Understanding RSPO stakeholders’ perceptions can enrich the current debate about the sustainable production and consumption of palm oil that is usually informed by rigorous yet highly compartmentalized research.

ArtigosFuel switching in slum and non-slum households in urban India

Journal of Cleaner Production, v. 94, pp. 130-136. Abstract: Improving access to modern fuels is essential in developing countries for reducing adverse human health and environmental impacts caused by traditional fuels. Fuels use in developing countries is heterogeneous across households. This paper estimates drivers of fuel switching in non-slum and slum households in urban India, using a discrete choice model on a nationally representative micro data. The choices considered are three categories of cooking fuels: traditional – firewood, dung, crop residue and coal/charcoal; modern – kerosene and liquefied petroleum gas (LPG); and mixed fuels. The results suggest that the patterns of fuels use are consistent with the energy ladder theory in urban India. In addition to income, the major determinants of modern fuels uptake are fuels prices, access to electricity and water supply, and education attainment. The increasing price of LPG affects the willingness to change fuels for low-income non-slum and the high-income slum households negatively. The analyses make a strong case for applying differential subsidies on modern fuels employing multidimensional aspects of poverty. Moreover, there is a need for partial diversion of existing fuels subsidies on improving physical and social capitals, which will result in uptake of modern fuels, particularly among disadvantaged communities.

ArtigosFrom global ‘North–South’ to local ‘Urban–Rural’: A shifting paradigm in climate governance?

Urban Climate, v. 14, pp. 529-543. Abstract: As the world takes an unprecedented rural–urban population tilt, the 21st century poses a challenge in further tinkering the internationally evident disparities in access and allocation of carbon. Traditionally, inequalities have been negotiated from economic or ‘state of development’ perspective. This research, to our knowledge is the first of its kind that plots carbon emission of over 200 nations/territories against a spatial framework. The study argues that existing dualities in the international climate change governance, evident in the so called global ‘North–South’ economic divide, has a stronger component of ‘Urban–Rural’ spatial disparity in the making, which is likely to further precipitate into a much local but complex dynamic, particularly relevant to the developing world, that face the double challenge of rapid urbanization and environmental sustainability. The paper discusses the ethical, empirical and governance gaps in climate governance related to the urban–rural carbon dynamics and conclude with a future pathway, committed to procedural justice and sub-nationalization of carbon governance, fairly acknowledging carbon flows at the local level through standard inventories based on consumption criteria. The research offers a shifting paradigm in global climate governance, in view of the inclusion of cities as Goal 11 within the upcoming sustainable development goals and the UNFCCC COP21 to be held in Paris in 2015 and beyond.

ArtigosBiofuels in sub-Sahara Africa: Drivers, impacts and priority policy areas

Renewable and Sustainable Energy Reviews, v. 45, pp. 879-901. Abstract: There has been a growing interest in jatropha- and sugarcane-based biofuels across Sub-Sahara Africa. Biofuel expansion in the region reflects policy concerns related to energy security, poverty alleviation and economic development. However, biofuels have also been linked to numerous environmental and socioeconomic impacts such as GHG emissions, water availability/pollution, deforestation, biodiversity loss, poverty alleviation, energy security, loss of access to land and food security to name just a few. Yet there is (a) an insufficient understanding of these impacts (and their synergies) in Sub-Sahara Africa, and (b) a lack of policies that could regulate the biofuel sector and ensure its viability while at the same time preventing its negative impact. The aim of this literature review is to synthesize the current knowledge about biofuel impacts in Africa and to identify priority policy areas that should be targeted for enhancing biofuel sustainability in the continent. The findings of this review indicate that biofuel impacts can be positive or negative depending on several factors such as the feedstock, the environmental/socio-economic context of biofuel production, and the policy instruments in place during biofuel production, use and trade. In most cases there are significant trade-offs but at least part of the negative impacts can be mitigated through careful planning. The incomplete and piecemeal understanding of these trade-offs combined with agronomic, institutional and market failures are currently the most important barriers for the viability and sustainability of biofuel investments in the continent.

ArtigosA life cycle co-benefits assessment of wind power in China

Renewable and Sustainable Energy Reviews, v. 41, pp. 338-346. Abstract: Wind power can help ensure regional energy security and also mitigate both global greenhouse gas and local air pollutant emissions, leading to co-benefits. With rapid installation of wind power equipment, it is critical to uncover the embodied emissions of greenhouse gas and air pollutants from wind power sector so that emission mitigation costs can be compared with a typical coal-fired power plant. In order to reach such a target, we conduct a life cycle analysis for wind power sector by using the Chinese inventory standards. Wind farms only release 1/40 of the total CO2 emissions that would be produced by the coal power system for the same amount of power generation, which is equal to 97.48% of CO2 emissions reduction. Comparing with coal power system, wind farms can also significantly reduce air pollutants (SO2, NOX and PM10), leading to 80.38%, 57.31% and 30.91% of SO2, NOX and PM10 emissions reduction, respectively. By considering both recycling and disposal, wind power system could reduce 2.74×104 t of CO2 emissions, 5.65×104 kg of NOX emissions, 2.95×105 kg of SO2 emissions and 7.97×104 kg of PM10 emissions throughout its life cycle. In terms of mitigation cost, a wind farm could benefit 37.14 US$ from mitigating 1ton of CO2 emissions. The mitigation cost rates of air pollutants were 7.94 US$/kg of SO2, 10.79 US$/kg of NOx, and 80.79 US$/kg of PM10.Our research results strongly support the development of wind power so that more environmental benefits can be gained. However, decentralized wind power developers should consider not only project locations close to the demand of electricity and wind resources, but also the convenient transportation for construction and recycling, while centralized wind power developers should focus on incorporating wind power into the grids in order to avoid wind power loss.

ArtigosInnovation in retail and the service-dominant logic: case studies in Brazilian retail networks

Business and Management Review, v. 4, n. 12, p. 401-413. Abstract: This paper seeks to develop an empirical validation of the service product formulation developed by Gallouj (2002) and its relationship with the retail sector as a service based on service dominant logic (VARGO; LUSCH, 2004). From the analysis of two case studies of major Brazilian retailers we concluded that innovation pursued by these retailers was produced by internal initiatives designed to generate sales growth and increase interaction with customers. Among the innovations investigated, only two were imitated by others, and even after the models had been replicated the company continued to maintain its competitive advantage generated through innovation.

ArtigosIndução de inovações em serviços: compras governamentais para a inovação ou compras de inovações?

Revista Gestão & Tecnologia, v. 15, n. 2, pp. 186-210. Resumo: Este estudo tem por objetivo investigar a relação entre a contratação de serviços de software pelo governo federal e o surgimento de inovações nas empresas desenvolvedoras sob a premissa teórica de uso das compras para a inovação. Adota-se abordagem integradora para o estudo da inovação em economias de serviços e utiliza-se o Chain-Linked Model para a compreensão do processo de indução. Tem-se um estudo de casos múltiplos, com dez unidades de análise. Coletam-se relatos por entrevistas semiestruturadas com profissionais de perfis estratégico e técnico identificando inovações em três momentos: pré-venda, prestação de serviços e pós-venda. Utiliza-se codificação temática para a construção de categorias para a análise dos relatos coletados. Os resultados apontam surgimento de inovações apesar da não intencionalidade governamental em sua indução, contrariando a premissa teórica de uso das compras para a inovação. As soluções inovadoras desenvolvidas mostram-se mais voltadas ao atendimento a parâmetros burocráticos que à obtenção de benefício econômico e à geração de soluções inéditas na economia, o que restringe sua difusão no mercado e limita sua aplicação à esfera governamental.

ArtigosOrganizing for Ambidexterity: A Paradox-based Typology of Ambidexterity-related Organizational States

BAR – Brazilian Administration Review, v. 12, n. 4. Abstract: This paper addresses the question of how organizations become ambidextrous over time, identifying requirements for organizations to become ambidextrous, understanding how ambidexterity may emerge as an organizational property, as well as exploring likely connections of the ambidexterity property and organizing a firm’s activities and work. Conceptualizing the exploration-exploitation relationship as a paradoxical one, we advance two necessary conditions for organizing for ambidexterity: fostering paradox-coping tactics and precluding paradox-related traps. The interplay of these two conditions gives rise to a typology of four ambidexterity-related organizational states: ambidexterity-lacking organizations, monolithic organizations, short-term ambidextrous organizations and long-term ambidextrous organizations. The paper identifies each state’s distinct strengths and challenges concerning organizing for ambidexterity, and discusses theoretical, practical and policy-making implications.

ArtigosO que motiva os hospitais brasileiros a buscar a acreditação?

Revista de Gestão em Sistemas de Saúde, v. 4, n. 1, pp. 17-28. Resumo: O objetivo desta pesquisa é identificar o que motiva os gestores hospitalares a buscar a acreditação. Foi realizado um survey com os 154 hospitais que atuam no Brasil e que no momento da pesquisa já possuíam ou estavam em processo de acreditação; destes, 101 (66%) responderam ao questionário. Os resultados indicam que a motivação para a busca da acreditação é um construto multidimensional e que aumentar a segurança do paciente é um dos principais motivadores. Surpreendentemente, a acreditação é vista como o início de um processo em direção ao alcance da qualidade e não como o coroamento final deste processo.

ArtigosDeveloping learning capabilities through a quality management program

The Service Industries Journal, v. 35, n. 9, pp. 483-498. Abstract: This study examines the development of learning capabilities through the implementation of a quality management program in services, based on a case study of transplantation management. The findings show how the introduction of an online system, based on a quality management program, underpinned the knowledge-building capacity of the organization. The results contribute to service literature by addressing how a quality management program links to organizational learning process directly and through building-up organizational knowledge. The implementation of a quality management program allows knowledge building through identification and socialization of tacit knowledge and combination of explicit knowledge. The development of learning capabilities fostered by the introduction of this program occurs under conditions that contribute to the building-up of organizational knowledge. Organizational learning is enhanced during this implementation through an incremental process that detects errors and corrects behavior and/or alters organizations premises, standards and values. This organizational learning helps to upgrade the overall process.

ArtigosAsset selection in socially responsible Brazilian stock funds

Business Management Review (BMR), v. 4, n. 5, pp. 721-730. Abstract: The Brazilian mutual fund industry is the fifth largest in the world. We produced a questionnaire based on well-known international methodologies to evaluate the asset selection practices of Brazilian SRI stock funds. We also compare industry allocations among funds and local stock indices. There were nine active Brazilian SRI stock funds by the end of 2011. There are more than 400 independent asset managers in Brazil but none managed a SRI fund.  Asset managers employed by large financial conglomerates with vast retail clienteles manage them, suggesting that SRI funds may be part of an institutional image strategy. Brazilian SRI stock funds lack asset selection sophistication and need to improve the disclosure of their practices. SRI fund managers possibly make up for their poorer practices by informally indexing because their industry allocation is remarkably similar to a corporate sustainability stock index and across funds.

ArtigosModeling the sovereign spreads via threshold cointegration: evidence from Brazil

WSEAS Transactions on Business and Economics, v. 12, pp. 354-362. Abstract: This paper analyses the dynamics of the Brazilian sovereign spread and its statistically significant connection with some selected variables by applying linear and threshold cointegration methods. We statistically test the effects of the recent subprime crisis finding strong equilibrium relations, stable enough to exhibit cointegrated behavior before and after the subprime crisis. The assumption of a threshold, linked to a certain level of market risk aversion, refines the methodology and brings flexibility to the modeling strategy. The final VECM model indicates the External debt and the volatility index VIX as the key drivers of the Brazilian sovereign spread. The findings suggest that, with the onset of the crisis, an automatic mechanism of adjustment between the spread and the VIX came into play while the market experimented an increasing risk aversion feeling. It becomes clear from the results that current beliefs on the economic fundamentals are not sufficient to deal with the market turbulence under a global crisis. We propose a methodology for assessing the robustness of the optimal threshold solution.

ArtigosTowards a sustainable tourism competitiveness measurement model for municipalities: Brazilian empirical evidence

Revista de Turismo y Patrimonio Cultural, v. 13, n. 6, pp. 1337-1353. Abstract: This study aims to contribute to sustainable tourism destination competitiveness research by proposing a systemic model for identifying the factors that impact Brazilian municipalities’ ability to create and integrate value -added tourism products to meet the needs of local communities and visitors and maintain the tourism competitiveness. It proposes that the available destination competitiveness models can be divided into three groups: i) aggregate indices; ii) conceptual and descriptive; and iii) explanatory and predictive. Six sustainable tourism competitiveness determinant factors were formulated: Tourism Infrastructure, Information and Communication Technology Infrastructure, Education, Heritage and Culture, Socioeconomic Development and Environmental Preservation. Four dependent factors related to tourism activity success were also postulated: Tourism Flow, Jobs, Wages and Revenue. All constructs were based on secondary indicators for Brazil’s 5,565 municipalities. The theoretical model was tested using Structural Equation Modeling (SEM).

ArtigosThe future of newspapers: an analysis from the consumer’s perspective

Journal of Marketing Trends, v. 2, p. 77-82, Abstract: The newspaper industry faces the most significant transformation process since its inception in the sixteenth century. Emerging new media compete for both people’s attention and advertisers’ budgets, creating an increasingly challenging environment. Survey conducted in Brazil using structural equation modeling showed that control and trust constructs mediated by content and services explain newspapers’ consumer satisfaction. Significant differences were found among consumers of print paper and newspaper websites coefficients. Based on the results are discussed and shown several strategic implications for the future of this industry, such as segmented customers and advertisers with strong effort based on customer relationship management.

ArtigosAdoção de inovações em mercados em rede: uma análise da introdução do livro didático digital no Brasil

Revista de Administração e Inovação, v. 11, n. 4, pp. 159-192. Resumo: Modelos de adoção de novas tecnologias são usualmente centrados no consumidor final. Entretanto, casos como a disputa entre tecnologias similares como Blu-Ray e HD-DVD sugerem que a difusão da inovação não depende apenas do consumidor, mas da criação de uma plataforma dominante capaz de atrair o máximo de complementares. O objetivo deste estudo é compreender a adoção de tecnologias em mercados mediados por plataformas, levantando os fatores que influenciam a inovação além do comportamento do consumidor. O estudo abordou a indústria editorial brasileira, investigando o impacto do livro didático digital neste setor. Entre abril e dezembro de 2012, foram realizadas entrevistas em profundidade com gestores de grandes editoras de livros didáticos do Brasil. O estudo sugere que, além de pais e alunos, outros atores influenciam a adoção do livro didático digital. Se editoras e professores estão reticentes, o governo, as plataformas de conteúdo digital e os Sistemas de Ensino são impulsionadores do livro didático digital. O estudo explora as motivações destes atores, sugerindo que a difusão de inovações em mercados em rede deve ser compreendida a partir de um olhar sistêmico, além dos modelos tradicionais.

ArtigosNíveis de governança corporativa da Bovespa e a revelação de informações ao mercado: uma comparação da divulgação de combinações de negócios em notas explicativas

Revista de Educação e Pesquisa Em Contabilidade (REPeC), v. 9, n. 2. Resumo: Neste trabalho, a revelação de informações associada à Governança Corporativa, a partir dos segmentos de listagem da Bolsa de Valores de São Paulo (Bovespa), é abordada pela divulgação de combinações de negócios nas demonstrações financeiras anuais. Com base no Pronunciamento Técnico CPC 15, foram analisadas as notas explicativas das demonstrações de 2012 das empresas listadas na Bovespa, considerando os segmentos diferenciados de listagem, para investigar se os segmentos de maior nível de governança apresentariam também maior nível de divulgação. As informações publicadas foram analisadas quanto ao tipo: simples, descritivas e detalhistas, de maneira descritiva e com confirmação estatística, através dos testes de Mann-Whitney para comparação entre os segmentos de Novo Mercado e Mercado Tradicional e de Wilcoxon, para comparação dos blocos de informações. Não foram encontradas diferenças significativas no nível de divulgação atribuídas à governança, entretanto, constatou-se menor divulgação conforme maior a complexidade da informação requerida. Os resultados apontam para uma maior sensibilidade ao tipo de informação relacionada aos segmentos de listagem, uma abordagem aplicável a outros pronunciamentos normativos ou outros indicadores de Governança Corporativa.

ArtigosInsolvência empresarial: um estudo sobre as distribuidoras de energia elétrica brasileiras

Revista Contemporânea de Contabilidade, v. 12, n. 27, pp. 27-60. Resumo: O objetivo deste trabalho é descobrir quais são os indicadores financeiros e operacionais mais relevantes para a explicação da insolvência no setor de distribuição de energia elétrica no Brasil. Além da grande relevância do setor para a economia brasileira, recentemente a Agência Nacional de Energia Elétrica emitiu a Nota Técnica nº 353/2014 visando criar mecanismos de acompanhamento constante da sustentabilidade econômico-financeira dessas distribuidoras. Para o estudo, foi utilizada a técnica de regressão logística, e a amostra utilizada foi composta pelas empresas de distribuição de energia que tiveram cadastro na Comissão de Valores Mobiliários, ao menos em algum dos anos entre 1997 e 2014. Os resultados foram consistentes em mostrar que os indicadores Índice de Cobertura dos Juros, Liquidez Geral e FEC/FEC Regulatório foram relevantes para explicar a insolvência das empresas respectivamente para dois anos antes, um ano antes, e para o mesmo ano da análise.

ArtigosDescontinuidade de empresas brasileiras do setor de material básicoNo período compreendido pré e pós a crise do subprime

Race: Revista de Administração, Contabilidade e Economia, v. 14, n. 1, pp. 171-196 . Resumo: Descontinuidade de empresas é um tema cada vez mais estudado no campo da contabilidade, das finanças, dos negócios e da computação em decorrência do considerável impacto social causado pelo fracasso corporativo de uma entidade. Bancos, investidores, auditores, gerentes, fornecedores, empregados e muitos outros têm grandes interesses na acurácia da previsão de continuidade de uma companhia. Ainda há questões pouco estudadas na modelagem de previsão de insolvência. O desequilíbrio ou desbalanceamento dos dados sobre insolvência é uma dessas questões; em ambientes econômicos típicos o número de empresas classificadas como solventes é bem maior do que o daquelas classificadas como insolventes. O objetivo deste estudo foi comparar as variáveis contábeis selecionadas nas amostras das empresas do setor de material básico antes e após a crise do subprime, aplicando tecnologias de aprendizagem de máquinas em problemas de previsão de insolvência, utilizando técnicas de balanceamento da base de dados com (etapa de) seleção de atributos e, a partir disso, obter informações contábeis que levem a explicações das diferenças ocorridas na descontinuidade das empresas estudadas. Esta pesquisa é de natureza aplicada com abordagem quantitativa; quanto ao objetivo, é descritiva.

ArtigosLost in participation: How local knowledge was overlooked in land use planning and risk governance in Tōhoku, Japan

Land Use Policy, v. 52, pp. 543-551. Abstract: This article aims to identify gaps in public participation in land use planning to improve risk governance, using the case of the Great East Japan Earthquake (GEJE) in 2011. Overreliance on technical information and on the opinion of experts is occurring side by side along with negligence of local knowledge and lack of effective public participation in decision-making, creating a sense of overconfidence regarding scientific knowledge and new infrastructure’s abilities to withstand future disasters. Using the case study method in GEJE, our research identified three main overall gaps in participation. Firstly, a lot of local knowledge from previous experiences was not incorporated into land use plans in the region even after similar events in the past. Secondly, there was technical information that alerted to possible risks for land use in certain areas, but this information did not impede development in risk areas due to lack of effective participation in the land use planning processes. Finally, Japan allows participation in many land use planning process, but some of the most important decisions, such as on the sitting of nuclear plants had little or any local participation. Thus, strengthening public participation in land use by closing those three gaps could improve risk governance and resilience of localities to cope with large natural and technological disasters in the future.

ArtigosDeterminants of urban mobility in India: Lessons for promoting sustainable and inclusive urban transportation in developing countries

Transport Policy, v. 50, pp. 106-114. Abstract: Studies from developed economies have analyzed the key factors for understanding urban mobility, which are important to design appropriate interventions to reduce the volume of transport needs and to promote more sustainable modes of transportation. However, there are limited studies in urban areas of developing economies, which can hinder our capacity to formulate sustainable transport policies that are fit for the reality of those countries. In order to fill this gap, this study quantifies the influence of city features and socio-economic and socio-cultural variables on mobility patterns to identify evidence-based policy interventions for promoting more inclusive and sustainable transportation paths. The research estimates the amount of public and private transport (proxied by out-of-pocket travel expenditure) and modal choices, employing multivariate analyses, using a nationally representative household survey from the 98 largest Indian cities. Findings reveal that densification in Indian cities reduces the amount of transport as well as enhances the probability of using public transport. Small and medium sized cities predominantly use private transport, whereas large cities prefer public transport but lack non-motorized transportation. Moreover, income is the most important determinant of the amount of transport and the use of motorized and private transport. The top quintile is the only with positive income elasticity of transport demand. Results show that public and non-motorized transport infrastructures will provide sustainable and inclusive development, besides other co-benefits, such as energy security. Based on these findings, several policy recommendations are proposed to improve the sustainability and inclusivity of urban mobility in Indian cities.

ArtigosAn integrated supply-demand model for the optimization of energy flow in the urban system

Journal of Cleaner Production, v. 114, pp. 269–285. Abstract: This research aims to develop a bottom-up integrated supply-demand model to assess the optimal performance of urban energy systems. To this end, an optimization model founded on the principles of microeconomics was developed and deployed using mathematical programming. In this model, the urban energy system is treated as an economic actor in the market seeking to establish an effective energy system to improve its overall resource efficiency with minimum total cost of the system. The model leads the system to achieve supply and demand energy commitments which include alternative energy and energy efficiency targets. In this paper, we apply the model to address the electricity deficiency in Delhi, India, as a case study. The results suggest that the saving at the end-user level could reach about 220 GWh per annum in the near future through improving energy end-use efficiency in the domestic sector. Besides this, the installation of about 40 MW from waste-to-electricity plants and generating approximately 210 GWh electricity from the rooftop solar PV by 2030 could enable a sufficient surplus for the power supply sector to meet the city’s electricity demand in the near future. Even though the system has some inherent limitations stemming from the assumptions of microeconomics and challenges related to data needs, the model can help the local actors, from governments to property owners, to find the best solutions for their energy needs. Such a modeling framework could address an organization’s sustainable performance at the urban level through the resource use optimization, minimization of waste, cleaner technologies and pollution limits which are used in achieving co-benefits and a broad range of Eco-Industrial Development (EID) goals.

ArtigosAssessing the Impact of the Realized Range on the (E)GARCH Volatility: Evidence from Brazil

Brazilian Business Review, v. 13, n. 2, pp. 1–26. Abstract: This paper investigates whether the inclusion of the realized range as regressor in the (E)GARCH volatility equation would add information to the process improving out-of-sample forecasts performance and providing more accurate estimates of the volatility persistence. Sixteen range measures at eleven data frequencies are tested using Brazilian stock market data. Several measures for assessing the im- provements in the fits were used including the likelihood ratio test, the persistence percentage decrease, and a formal statistical test for comparing forecasts errors from competing models. We found that for both the GARCH and EGARCH models there are always some realized range type at some frequencies bringing information to the volatility process with considerable persistence reduction.

ArtigosThe Influence of Sports Celebrity Credibility on Purchase Intention: The Moderating Effect of Gender and Consumer Sports-Involvement

Brazilian Business Review, v. 13, pp. 1–21. Abstract: This study investigates the effects of sport’s celebrity endorsement on purchase intention. More specifically, this study seeks to (1) identify the extent to which the sports celebrity’s credibility influences consumer purchase intention; (2) the extent to which gender moderates the effect of sports celebrity endorsement on purchase intention; and (3) to what extent consumer sports-involvement moderates the effect of a sports celebrity endorsement on purchase intention. One famous Brazilian soccer player and four product categories were used as stimuli. The research method used was a survey, which has included 1,025 respondents. Data analysis was performed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Structural equation modeling (SEM), using the ADF technique, was applied to test the substantive hypotheses. To test the hypotheses of the moderating effect of gender and consumer sports-involvement, the research used the multigroup analysis technique. The empirical results support the relationship between a sport celebrity’s endorsement and purchase intention. The moderating effects of gender and sports-involvement were also empirically supported, but only partially.

ArtigosA decisão de compra de veículos adaptados por consumidores com deficiência motora

Revista de Administração da UNIMEP. v. 14, n. 3, pp. 112-141. Resumo: Ainda que tal informação não seja amplamente divulgada, no Brasil as pessoas que tem alguns tipos de deficiência motora podem dirigir desde que o carro esteja adaptado às suas necessidades. A presente pesquisa tem como objetivo conhecer e explorar o processo de decisão de compra de carros adaptados por pessoas com deficiência motora no Brasil. A literatura sugere que veículos automotivos adaptados podem ser capazes de mudar as vidas de tais consumidores, mas pouco se conhece acerca das motivações ou dos problemas por eles enfrentados no processo de compra. A pesquisa foi realizada com base na netnografia, esse mostrou ser um bom caminho, uma vez que as pessoas com deficiência motora tendem a utilizar o ambiente online como forma de comunicação e de interação com outros indivíduos. A coleta de informações se estendeu por três anos e foi realizada em grupos de e-mails e em blogs. O material obtido em todas as etapas da coleta de dados passou pelo protocolo de análise de conteúdo.  As categorias de análise de resultados foram definidas usando as etapas do processo de decisão de compra: (i) Reconhecimento do problema; (ii) Busca de informações; (iii) Avaliação de alternativas; (iv) Decisão de compra; e (v) Avaliação pós-compra. Assim, o material analisado foi categorizado em cinco grupos que receberam os nomes dessas etapas. É interessante destacar que, para as PcD, tal processo na íntegra é denominado de “novela”. Ao descrever o processo de compra de um carro adaptado, muitos sujeitos da pesquisa apontaram dificuldades, e que o processo costuma gastar tempo, daí a utilização recorrente do termo “novela”. Os resultados da investigação teórico-empírica de base netnográfica mostram que, muitas vezes, a busca por autonomia inicia o processo da compra do carro, e que, em todas as etapas de tal processo, multiplicam-se as dificuldades que os consumidores com deficiências precisam enfrentar. Proprietários de veículos adaptados confirmaram que a almejada independência pode ser alcançada com o carro, a despeito das dificuldades enfrentadas para a aquisição, manutenção e utilização do veículo. Muitas possibilidades para pesquisas futuras podem ser consideradas com base nos resultados deste estudo exploratório. Os depoimentos indicaram que a falta de mobilidade urbana – evidenciada, por exemplo, nas dificuldades para se chegar aos locais de consumo e aquelas enfrentadas nos estacionamentos de centro comerciais sem vagas demarcadas – se relaciona intimamente à inibição de diversos papéis sociais como os de estudantes, trabalhadores e consumidores, os quais deveriam ser amplamente exercidos por parte das PcD. Sendo assim, pode ser um bom caminho para estudiosos em marketing empreender um esforço para buscar entender os impactos da falta de mobilidade urbana no consumo das pessoas com deficiências. Nas áreas de gestão de pessoas e de organizações, pode-se estudar esse impacto na forma como essas pessoas interagem com a empresa como trabalhadores.

ArtigosAutonomy at work: The perspective of a Group of Brazilian skilled workers

Latin American Business Review, v. 17, n. 4, pp. 289-313. Abstract: This study investigated the variety of understandings of autonomy at work from the perspective of a group of Brazilian skilled workers. The research method used was phenomenography, a qualitative and interpretative research approach. The results constitute a system that provides a comprehensive description of autonomy based on the variation in perspectives across the interviewees. The outcomes suggest that an overall sense of authorship regarding a broad range of decisions is inherent to the experience of autonomy. The findings also suggest that an expanded conception of autonomy includes not only professional but also personal and lifestyle aspects.

ArtigosBoard characteristics and compensation in Brazilian listed companies

International Journal of Disclosure and Governance, v. 13, pp. 309-328. Abstract: This article suggests that larger, better-governed, and lower ownership concentration companies have less homogeneous and passive boards, but pay more to their senior managers and directors. These companies probably need better-paid professionals to cope with more complex compliance and business environments. We create two categorical variables named homogeneity and passivity scores that aggregate hand collected board member characteristics. More homogeneous and passive boards may grant larger director and senior management compensations under the managerial power hypothesis. On the other hand, larger and value increasing companies may pay more to their senior managers. Our findings suggest that less homogeneous and passive boards grant larger compensations in univariate tests. These results, however, do not transpire in multivariate tests. More homogeneous and passive boards are more frequent in smaller and higher ownership concentration companies, with poorer corporate governance and disclosure practices. It is possible that financial disclosure practices are more important then board characteristics. These results highlight the importance of disclosure and transparency efforts to improve investor relations and reduce the cost of capital in a high ownership concentration country.

ArtigosFuzzy logic in production sequencing: the case of a cosmetics manufacturer in Brazil

International Journal of Business Intelligence and Systems Engineering, v. 1, n. 1, pp. 2–31. Abstract: This study aims to develop a way to improve the production sequencing practice of a case company that manufactures cosmetics located in Brazil. Production sequencing is an activity that is part of production planning and control. Our goal is to provide ways to reduce sales loss due to product stock-outs through new practices found in the literature. Simultaneously, we aimed at increasing the number of different items without sales loss thereby helping the achievement of sales goals while improving the meeting of overall demand for products. The approach proposed here includes the development of a decision support tool based on fuzzy logic. Such approach proved to be a good alternative to overcome some of the problems encountered in the case company production sequencing activity. Furthermore, the developed decision support system enabled the organisation decision-making to be more agile and dynamic. Additionally, by facilitating the incorporation of environmental complexity, our proposed solution helped harmonise decision-making across different areas of the company.

ArtigosFactors influencig software migration decision: case studies of Acerlormittal Tubarão and the city government of Serra, Espirito Santo

JISTEM – Journal of Information Systems and Technology Management, v. 13, n. 3. Abstract: The objective of this research is to identify the factors that influence the migration of free software to proprietary software, or vice-versa. The theoretical framework was developed in light of the Diffusion of Innovations Theory (DIT) proposed by Rogers (1976, 1995), and the Unified Theory of Acceptance and Use of Technology (UTAUT) proposed by Venkatesh, Morris, Davis and Davis (2003). The research was structured in two phases: the first phase was exploratory, characterized by adjustments of the revised theory to fit Brazilian reality and the identification of companies that could be the subject of investigation; and the second phase was qualitative, in which case studies were conducted at ArcelorMittal Tubarão (AMT), a private company that migrated from proprietary software (Unix) to free software (Linux), and the city government of Serra, in Espírito Santo state, a public organization that migrated from free software (OpenOffice) to proprietary (MS Office). The results show that software migration decision takes into account factors that go beyond issues involving technical or cost aspects, such as cultural barriers, user rejection and resistance to change. These results underscore the importance of social aspects, which can play a decisive role in the decision regarding software migration and its successful implementation.

ArtigosThe Development of the Mozambican Banking Sector and Strategic Fit of Mergers and Acquisitions: A Two-Stage DEA Approach

African Development Review, v. 28, n. 4, pp. 444–461. Abstract: This paper examines the strategic fit of mergers and acquisitions (M&A) in Mozambican banks, using a two-stage data envelopment analysis (DEA) approach to compute the impact of contextual variables on efficiency scores and returns to scale of the resulting virtual merged banks. In an ‘M&A DEA’ model, different pairs of bidder and target companies are considered. In the first stage an M&A DEA model is used. Simplex regression is adopted in the second stage. The results reveal that ownership (public or foreign) impacts virtual efficiency levels. However, the findings also show that care must be exercised with M&A because the resultant banking organization could be oversized when foreign ownership is predominant, especially when public ownership is low. Given the relative sizes of the markets in terms of productive resources, M&A involving Mozambican banks can easily lead to decreasing returns to scale. Thus, a greater emphasis should be given to merging purely public banks with foreign ones and vice versa.

ArtigosPredicting efficiency in Islamic banks: An integrated multicriteria decision making (MCDM) approach

Journal of International Financial Markets, Institutions and Money, v. 45, pp. 126-141. Abstract: This paper presents an efficiency assessment of the 114 Islamic banks from 24 countries using the Technique for Order Preference by Similarity to the Ideal Solution (TOPSIS). TOPSIS is a multicriteria decision making technique similar to Data Envelopment Analysis (DEA), which ranks a finite set of units based on the minimization of distance from an ideal point and the maximization of distance from an anti-ideal point. In this research, TOPSIS is used first in a two-stage approach to assess the relative efficiency of Islamic banks using the most frequent indicators adopted by the literature. Then, in the second stage, neural networks are combined with TOPSIS results as part of an attempt to produce a model for banking performance with effective predictive ability. The results reveal that variables related to both country origin and cost structure have a prominent impact on efficiency. Findings also indicate that the Islamic banking market would benefit from higher level of competition between institutions.

ArtigosEfficiency of municipal schools in Rio de Janeiro: evidence from two-stage DEA

Journal of Economics and Economic Education Research, v. 17, no 3, pp. 147-166. Abstract: This paper analyzes the efficiency of 465 elementary schools run by the city of Rio de Janeiro by means of a two-stage data envelopment analysis, according to the model proposed by Simar and Wilson (2007). The first stage of this study analyzes school efficiency; in the second stage, from a bootstrapped truncated regression, the variables that have a significant impact on efficiency are identified. This paper, in addition to suggestions for public policy in education, finds that higher student socioeconomic level does not correlate with higher efficiency. However, longer school days, student discipline-related problems, and the lack of solidarity programs or community clean-up programs correlate with lower efficiency.

ArtigosBrazilian Healthcare Professionals: A Study of Attitudes Toward Organ Donation

Transplantation Proceedings, v. 48, n. 10, pp. 3241-3244. Abstract Background: Healthcare professionals have a crucial role in organ donation and transplantation processes. Their attitude toward organ donation can affect public opinion and the donation decision made by deceased donors’ relatives. The objectives of the study were to analyze the attitude of medical and nursing personnel toward deceased organ donation in two hospitals in Rio de Janeiro, Brazil, and the factors that can affect this attitude. Methods: A random sample (n = 162) was selected from the population of nurses and physicians in the hospitals analyzed. The sample was stratified by age, sex, marital status, religion, professional category, and educational level. A validated questionnaire addressing psychosocial aspects of organ donation was used to evaluate attitudes. The χ2 and Mann-Whitney U tests were applied for statistical analysis. Results: Of personnel surveyed, 86.4% (n = 140) were in favor of deceased organ donation, whereas 11.1% (n = 18) were not sure and 2.5% (n = 4) were against. The favorable attitude was related to the following aspects: (1) educational level, (2) having spoken with family members about organ donation, (3) having a chronic disease, (4) favorable attitude of one’s family, (5) belief that organ donation can save lives, (6) concerns about body manipulation, illegal trade of organs, and organ donation being against God’s will, (7) feeling proud of working with organ donation/transplantation, (8) self-assessment of experience and knowledge in organ donation/transplantation activities (P < .05). Conclusions: Deceased organ donation is well accepted among the healthcare professionals surveyed, and the attitude is affected by socio-personal variables.

ArtigosContagious content: Viral video ads identification of content characteristics that help online video advertisements go viral

Revista Brasileira de Marketing – ReMark, v. 15, no. 4, pp. 448-458. Abstract: Why do some online video advertisements go viral while others remain unnoticed? What kind of video content keeps the viewer interested and motivated to share?  Many companies have realized the need to innovate their marketing strategies and have embraced the newest ways of using technology, as the Internet, to their advantage as in the example of virality. Yet few marketers actually understand how, and academic literature on this topic is still in development.  This study investigated which content characteristics distinguish successful from non-successful online viral video advertisements by analyzing 641 cases using Structural Equation Modeling. Results show that Engagement and Surprise are two main content characteristics that significantly increase the chance of online video advertisements to go viral.

ArtigosAssessment of Factors Related to Adherence to Treatment in Liver Transplantation Candidates

Transplantation Proceedings, v. 48, n. 7, pp. 2361-2365. Abstract Background: The relevance that adherence to treatment plays in liver transplantation, and the impact this factor may have on the success of treatment, are fundamental in assessing the variables which affect patient adherence during the pretransplantation period. Objectives: This study aims to determine factors that affect liver transplant candidates’ adherence to treatment, and analyze the association between adherence, socioeconomic and demographic factors, clinical characteristics, and patient understanding about the disease and liver transplantation. Methods: This epidemiological, observational, and prospective study included 62 patients registered in the technical database of the Universidade Federal de São Paulo during the period November 2012–May 2014. The dependent variable was adherence to treatment among liver transplantation candidates, and the independent variables included understanding the disease and the transplantation process, and depression and anxiety symptoms among liver transplantation candidates. Results: Work situation (P = .038), understanding about the disease (P = .002), and use of laxatives (P = .045) were the factors related to statistically significant adherence, and it can be concluded that implementation of an educational program may increase adherence up to 3.48 times in the pretransplantation phase, as adherence was 3.48 times lower in patients who reported little or no knowledge of the disease or the procedure.

ArtigosKnowledge Creation in Hybrid Organisations: A Case Study in a Quasi-Governmental Organisation

Journal of Information & Knowledge Management, volume 15, no. 3. Abstract: The organisational structure of hybrid organisations is affected by multiple institutional influences, considering power flows and organisational processes from the public and private sectors. Given this dynamic, the process of knowledge creation presents some particularities. This article aims to understand the specificities of knowledge creation in large hybrid organisations characterized as large structures with multiple institutional influences, based on a case study of a Brazilian organisation — SESC. Data collection was based on four sources: (i) documental research; (ii) questionnaire with evocative phrases; (iii) structured interviews; and (iv) direct observation. The content analysis technique was used to codify and interpret information. The results offer significant contributions for these hybrid organisations, indicating that they need to access how the bureaucratic model inhibits their knowledge creation, while restricting tacit knowledge sharing, causing the lack of sense of urgency and reducing autonomy and creativity.

ArtigosEfficiency in Chinese seaports: 2002–2012

Maritime Economics & Logistics v. 18, pp. 295–316 Abstract: This article assesses the impacts of cost and operational variables on major Chinese ports by means of a stochastic frontier model on a panel data from 2002 to 2012. More precisely, both random and fixed-effect stochastic models are used in the analyses to cross-validate the results. Findings suggest that there is considerable heterogeneity in China’s seaports, affecting their cost efficiency estimation. Moreover, remote port locations are shown to exhibit lower efficiency, while larger ports appear to be more efficient. Port heterogeneity is therefore shown to be a policy criterion the importance of which could in no way be understated.

ArtigosA perspectiva de redes na internacionalização de empresas brasileiras de construção civil: o caso Vale e BNDES em Moçambique

Revista Ibero-Americana de Estratégia (RIAE), v. 15, no. 3. Resumo: A proposta deste artigo é analisar, a partir da perspectiva de redes, o processo de internacionalização de empresas brasileiras e em como esse movimento é influenciado por entes governamentais. Em outros termos, objetiva-se pensar os negócios internacionais não como sendo uma atividade que afeta apenas uma empresa, mas que tenha um impacto sobre todas interações dentro de suas redes, as quais congregam a esfera pública. O referencial teórico que deu suporte para análise do caso foi um framework integrativo entre a perspectiva de redes e a teoria institucionalista. O método de pesquisa aplicado foi o estudo de caso, realizado a partir da triangulação na coleta e análise dos dados empíricos, visando uma maior visão a respeito da cadeia internacionalizada. A conclusão deste estudo foi que a internacionalização das grandes empreiteiras brasileiras para Moçambique e a consolidação delas nesse país tiveram e ainda têm grande influência do papel de suas redes.

ArtigosIndicadores de eficiência no processo de doação e transplante de órgãos: revisão sistemática da literatura

Revista Panamericana de Salud Pública, v. 40, n. 2. Resumo Objetivo: Verificar, por meio de revisão sistemática da literatura, os indicadores utilizados para acompanhar e controlar o processo de doação e transplante de órgãos e elaborar um painel para tipificação dos indicadores descritos na literatura. Método: Em novembro de 2014, foi realizada uma busca sistemática da literatura nas bases de dados da Biblioteca Virtual em Saúde (BVS), EBSCO, Emerald, Proquest, Science Direct e Web of Science. Foram utilizados os descritores “eficiência”, “indicadores”, “doação de órgãos”, “captação de órgãos”, “transplante de órgãos” e seus correspondentes na língua inglesa. Dos 344 artigos retornados pela busca, foram selecionados e revisados para análise dos indicadores de eficiência 23 artigos originais publicados de 1992 a 2013. Resultados: Foram identificados 117 indicadores de eficiência, os quais foram agrupados por similaridade de conteúdo e divididos em três categorias: 1) 71 indicadores relacionados à doação de órgãos, envolvendo estatísticas de mortalidade, notificação de morte encefálica, situação clínica dos doadores e exclusão por razões médicas, atitude da família, confirmação da doação e extração dos órgãos; 2) 22 indicadores relacionados ao transplante de órgãos, envolvendo a cirurgia propriamente dita e o acompanhamento pós-transplante; e 3) 24 indicadores relacionados à demanda por órgãos e aos recursos dos hospitais envolvidos no processo. Conclusões: O alto número de indicadores encontrados mostra que, mesmo sendo o transplante de órgãos um fenômeno recente, os estudiosos do processo têm buscado formas de mensurar o seu desempenho. Contudo, há pouca padronização dos indicadores e o foco é predominantemente na etapa da doação, sugerindo lacunas na mensuração da eficiência em outros pontos do processo. Além disso, ainda há carência de indicadores em importantes etapas, como na distribuição de órgãos (por exemplo, indicadores de perda de órgãos) e no pós-transplante (por exemplo, indicadores de sobrevida e qualidade de vida após a cirurgia de transplante).

ArtigosPredicting Efficiency in Angolan Banks: A Two-Stage TOPSIS and Neural Networks Approach

South African Journal of Economics, v. 84, n. 3, pp. 461-483. Abstract: This paper presents an efficiency assessment of the Angolan banks using Technique for Order Preference by Similarity to the Ideal Solution (TOPSIS). TOPSIS is a multi-criteria decision-making technique similar to data envelopment analysis, which ranks a finite set of units based on the minimisation of distance from an ideal point and the maximisation of distance from an anti-ideal point. In this research, TOPSIS is used first in a two-stage approach to assess the relative efficiency of Angolan banks using the most frequent indicators adopted by the literature. Then, in the second stage, neural networks are combined with TOPSIS results as part of an attempt to produce a model for banking performance with effective predictive ability. The results reveal that variables related to cost structure have a prominent negative impact on efficiency. Findings also indicate that the Angolan banking market would benefit from higher level of competition between institutions.

ArtigosSo hard to say goodbye? An investigation into the symbolic aspects of unintended disposition practices

Journal of Consumer Behaviour, v. 15, no. 5, pp. 420-429. Abstract: Even though disposition is present in the consumer behavior research agenda, most of the studies focus mainly on intentional movements of products leaving the home. The present article describes a less conscious and co-incidental journey of products into a liminal zone between use and disposal inside homes. A qualitative field study, based on the itinerary method, was undertaken with a group of 26 affluent women in Brazil. The findings show that consumers maintain purgatories – “forgotten” repositories of products no longer in use – as an in-home disposition practice. The aspects and functioning of purgatory are also detailed, through a typology of purgatories and a discussion of specific strategies to deal with cluttering as a consequence of product accumulation inside homes. Finally, purgatories emerge as a contemporary consumer solution to deal not with individual products but with product collectivities’ disposition.

ArtigosDo African microfinance institutions need efficiency for financial stability and social outreach?

South African Journal of Science, v. 112, n. 9-10. Abstract: Microfinance institutions (MFIs) have the dual objective of providing social welfare and financial stability. We evaluated the financial efficiency of MFIs in sub-Saharan African countries by comparing their regional performances during the period 2004-2013. We addressed prevailing MFI heterogeneity by using the concept of ‘metafrontier’. The results showed that on an average, more than half the MFIs showed a drop in productivity. The measure of how much one country gets closer to or further away from world frontier technology is commonly known as the TGC score. In world frontier technology, East and South Asian countries have taken the lead (TGC score 1.0048) while sub-Saharan African countries lag behind (TGC score 1.0020). Most East and South Asian countries have a TGC score of 1, and most sub-Saharan African countries have a TGC score less than 1. This signifies that Asian countries lead world frontier technology and most African countries do not. The decomposition of efficiency scores showed that with regard to technical changes, African nations had progressed on average only 0.01%, and efficiency change scores had regressed by 0.59% annually.
Significance:
• First efficiency study on microfinance institutions and their heterogeneity in Africa.
• The results show robust discrimination among the efficiency scores.

ArtigosPeasants’ poverty and inequality in Angola

Social Indicators Research, v. 128, n. 2, pp. 751–761. Abstract: This paper analyses peasants’ poverty and inequality in Angola from 2004 to 2013 using a spatial panel data model. Peasant farming is the most common economic activity in Africa. Therefore the relationship between this economic activity (peasant farming), poverty and inequality is investigated. Other covariates include public expenditure, access to education and medical services and agricultural non-governmental organization that help peasants in Angola. Several spatial models are adopted, first a spatial Durbin model, then the spatial error model, the spatial autoregressive model and finally a spatial model with endogeneity, the Arellano–Bover (J Econom 68:29–51, 1995) spatial system panel model. The results reveal that spatial autocorrelation occurs in Angola and peasants are affected by inequality but not by poverty. The paper is not comparable with analysis of peasants in Africa because it adopts a spatial analysis. Moreover, the positive but statistically insignificant relationship with poverty means that there is no correlation between peasantry and poverty but there is a negative correlation between the Gini coefficient and peasantry.

ArtigosAgency conflicts in Brazilian stock funds: categorizing funds in clientele and fee types

Corporate Ownership & Control, v. 13, n.  4, pp. 458-469.  Abstract: This article investigates the behavior of equity mutual funds at calendar semester ends in Brazil between 2004 and 2013. Results suggest that the sampled funds present positive abnormal returns on the last trading day of calendar semesters, followed by negative abnormal returns on the subsequent day. Funds oriented to retail investors and those that charge incentive fees are more likely to display this abnormal return behavior. Exclusive funds present the smallest incidence of abnormal returns. There seems to be evidence of portfolio pumping.

ArtigosMultiplex appropriation in complex systems implementation: the case of Brazil’s correspondent banking system

MIS Quarterly, v. 40, n. 2, pp. 461-473. Abstract: When user needs do not align with system designers’ visions, new technology implementation becomes a complex process as users appropriate the new technology to meet their needs. Prior studies recognize this complexity, but focus on the complex implementation of simple systems in which user groups are well defined and the IT artifact is the primary change. We extend the research lens by examining the implementation of the Brazilian correspondent banking system, a complex system involving multiple actors, system elements, and settings intended to address the social problem of financial exclusion. Our case study comparison of two settings—retail stores and post offices—reveals that actors’ appropriations extended beyond the IT artifact to include technical, role, usage, social, and policy appropriations. The intended users (poor clients in remote and underserved areas) barely interacted with the IT artifact or other system elements; instead, they relied upon remote bankers (correspondents) to appropriate the system on their behalf. Because rewards, incentives, and constraints differed by setting, correspondents’ appropriations differed by setting. We call the resulting mix of appropriations across multiple elements by multiple actors in multiple settings multiplex appropriation. Complex societal challenges often involve multiple users in multiple settings with varied needs and few technology skills; thus, designing systems to meet user requirements may prove impossible. Instead, allowing multiplex appropriation might foster system success because, rather than forcing a global alignment among system elements or trying to ascertain multiple user needs, it allows for multiple local alignments of system elements that fit local settings

ArtigosMobile social money: an exploratory study of the views of managers of community banks

Revista de Administração, v. 51, n. 3. Abstract: This article aims to evaluate the adoption potential of a digital social currency model using mobile phones. Despite the significant literature concerning both social currencies and mobile payments, there are few studies with a focus on social currencies being operationalized via mobile payments. An important aspect of the literature on mobile payments and social currencies is the role that both instruments may play in the financial inclusion. Despite the absence of lasting experiences for an empirical analysis in Brazil, we believe that there may be synergy between these two types of payment instruments. To evaluate the potential of a mobile digital social currency, we conducted interviews with community bank managers, focusing on their perceptions of acceptance of this innovative model in their communities. As a theoretical basis, we articulated the concept of transformational framing, originated from the perspective of interpretive frames of collective action. As a result, we identified a transformational discourse by which community bank managers create new meanings and understandings of this emerging payment system model.

ArtigosStock fund returns and macroeconomic variables in Brazil

Latin American Business Review, v. 17, n. 2, pp. 139-161. Abstract: This article tested the Burmeister, Roll, and Ross (1994) version of the Arbitrage Pricing Theory (APT) with Brazilian stock funds from 2002 to 2012 using the market and four macroeconomic risk factors as innovations. The market timing and time horizon risk factors were the only ones displaying consistent coefficient sign and high significance frequency across all periods and fund categories. Confidence, inflation, and business cycle risks were not as consistent. The APT explains historical fund returns better than the single Capital Asset Pricing Model, but it was not possible to obtain reliable estimates for the factors risk premia.

ArtigosSurvivorship bias in Brazilian stock funds

Economics Bulletin, v. 36, n. 2. Abstract: This article investigates the survivorship bias of a sample of 1119 equity mutual funds in Brazil between 2004 and 2013. There is indication that survivorship bias increases when very small funds and those that did not have share prices for at least 12 contiguous months are not discarded. Results indicate that the sample with non-surviving funds frequently presented average returns lower than a sample with only surviving funds in a given year. Association to a large financial conglomerate and longevity may also favor fund survivorship.

ArtigosÍndices Valor-Coppead, Carteiras de Ponderação Igualitária e de Mínima Variância

Revista Brasileira de Finanças, v. 14, n. 1, p. 45-64. Resumo: Este artigo apresenta a revisão da literatura que justificou a criação dos índices de ações Valor-Coppead igualmente ponderado e de variância mínima e dá detalhes sobre seu cálculo. Não havia índice brasileiro de ações com estas regras simples de formação de carteiras alcançáveis pelo investidor sem sofisticação. Um índice que use a carteira de menor variância na fronteira eficiente, com restrições sobre os pesos, oferece uma carteira otimizada menos afetada pelos erros nas estimativas. Carteiras igualmente ponderadas com até 20 ações apresentam desempenho superior à maioria dos fundos de ações nacionais e comparável ao da carteira de variância mínima com pesos restritos, mas métodos mais complexos de carteiras otimizadas podem superar a carteira de ponderação igualitária. O critério de formação segundo o Índice de Sharpe nos três ou quatro meses anteriores é relevante. A literatura revista respaldou que os índices Valor-Coppead podem ser padrões de desempenho relevantes para investidores sem sofisticação.

ArtigosEfficiency and productive slacks in urban transportation modes: A two-stage SDEA-Beta Regression approach

Utilities Policy, v. 41, pp. 31-39. Abstract: The performance of urban transportation modes is a critical issue for people’s mobility. This research analyses various transportation modes in 285 cities across the world from 2009 to 2012, exploring efficiency levels with a focus on productive capacity slacks. The idea is to better apprehend the resilience of different transport modes in terms of absorbing demand shocks, shedding some light not only in terms of the intrinsic characteristics of each mode but also on the demographic context. A novel approach derived from a two-stage combination of Stochastic Data Envelopment Analysis (SDEA) and Beta Regression was used to support the findings, which indicate the concentration of productive slacks on heavy metro and the need of specific solutions for mid-sized cities. Policy implications are then derived.

ArtigosBrazilian airline industry: Persistence and breaks

International Journal of Sustainable Transportation, v. 10, n. 9, pp. 794-804. Abstract: This article examines the degree of persistence and breaks in the Brazilian airline industry. For this purpose we use innovative fractional integration and autoregressive models, which are more flexible than the standard approaches employed in the literature. Our model focuses on three important series, namely revenue passenger kilometers (RPK), available seat kilometers (ASK), and load factor (LF = RPK/ASK), disaggregated into domestic and international series. We found first that all series are highly persistent with orders of integration above 0.5 in all cases, thus implying nonstationary behavior. However, for the domestic series mean reversion is also achieved, while orders of integration close to 1 or above 1 are obtained in the case of the international data. Moreover, a structural break is clearly identified in all the series. Policy implications are then derived.

ArtigosJob satisfaction and intention to quit: na empirical analysis of nurses in Turkey

PeerJ, v. 4. Abstract: The aim of this study was to identify the facets influencing job satisfaction and intention to quit of nurses employed in Turkey. Using a non-probability sampling technique, 417 nurses from six large private hospitals were surveyed from March 2014 to June 2014. The nurses’ demographic data, their job-related satisfaction and turnover intentions were recorded through a self-administered questionnaire. In this study, descriptive and bivariate analyses were used to explore data, and multivariate analysis was performed using logistic regression. Nurses’ job satisfaction was found at a moderate level with 61% of the nurses intended to quit. Nevertheless, nurses reported a high satisfaction level with work environment, supervisor support, and co-workers among the selected nine facets of job satisfaction. They also reported a low satisfaction level with contingent reward, fringe benefits, and pay. The impact of demographic characteristics on job satisfaction and intention to quit was also examined. The study revealed a negative relationship between job satisfaction and intention to quit the existing employment. Moreover, satisfaction with supervisor support was the only facet that significantly explained turnover intent when controlling for gender, age, marital status, education, and experience. The implications for nurse management were also described for increasing nurses’ job satisfaction and retention. This study is beneficial for hospital management to ensure proper nursing care that would lead to a better quality healthcare service.

ArtigosEfficiency Factors in OECD banks a ten year analysis

Expert Systems with Applications, v. 64, pp. 208-227. Abstract: This paper presents a performance assessment of 128 banks from 23 OECD countries from 2004 to 2013, using different financial criteria that emulate the CAMELS rating system. A robust TOPSIS approach for assessing bank efficiency is also developed and presented. First, alternative variable reduction techniques are employed to extract the major factors within each CAMELS criterion. This is done to mitigate collinearity issues. Then, TOPSIS is used to measure bank performance based upon these factors, equally weighted. A comprehensive analysis based on a weighted linear optimization model for multi-criteria classification is also performed, which detects any discrepancies from the original scores. Lastly, censored quantile regressions are combined with bootstrapped TOPSIS scores to produce a model for predicting the impact of different contextual variables on different efficiency quantiles. Results reveal that the effects of ownership, trend, and origin of the bank may vary with respect to efficiency levels, whether high or low.

ArtigosCost and learning efficiency drivers in Australian schools: a two-stage network DEA approach

Applied Economics, v. 48, n. 38, pp. 3577-3604. Abstract: This article explore performance issues in Australian public schools, using a two-stage DEA network model, which accounts simultaneously for both cost and learning efficiency levels. In the cost efficiency stage, different types of expenses and investments are employed to support a given number of students, teachers and administrative staff. In the learning efficiency stage, these groups of individuals help to produce important outputs related to performance in student tests and school rankings. Results indicate that Australian public schools are heterogeneous. Policy implications are also discussed.

ArtigosPredicting performance in ASEAN banks: an integrated fuzzy MCDM–neural network approach

Expert System, v. 33, n. 3, pp. 213-229. Abstract: This paper presents a performance assessment of 88 Association of Southeast Asian Nations banks from 2010 to 2013, using an integrated three-stage approach on financial criteria that emulates the CAMELS rating system. More precisely, fuzzy analytic hierarchy process is used first to assess the relative weights of a number of criteria related to capital adequacy (C), asset quality (A), management quality (M), earnings (E), liquidity (L), and sensitivity to market risk (S) based on the opinion of 88 Association of Southeast Asian Nations experts. Then, these weights are used as technique for order of preference by similarity to ideal solution inputs to assess their relative efficiency. Lastly, neural networks are combined with technique for order of preference by similarity to ideal solution results to produce a model for banking performance with effective predictive ability. The results reveal that contextual variables have a prominent impact on efficiency. Specifically, parsimony in equity leveraging derived from Islamic finance principles may be the underlying cause in explaining higher efficiency levels.

ArtigosEfficiency in Latin American airlines: A two-stage approach combining Virtual Frontier Dynamic DEA and Simplex Regression

Journal of Air Transport Management ,v. 54, pp. 93-103. Abstract: This paper presents an efficiency assessment of Latin American airlines, using VDRAM-DEA (Virtual Frontier Dynamic Range Adjusted Model – Data Envelopment Analysis). In VDRAM, the reference and DMU evaluation sets are different, thus allowing higher discrimination of scoring. In this research, the VDRAM model is used first in a two-stage approach. In the second stage, Simplex Regression is adopted to handle skewed and asymmetrical efficiency scores. The results corroborate previous studies and reveal that the impact of fleet mix and public ownership cannot be overlooked in Latin American airlines, which seem to be affected by insufficient load factors and hub and spoke systems. For the same reasons, although low cost carriers are an emerging trend in the region, it was not possible to confirm their higher efficiency levels. Besides, to some extent, these findings also show the absence of a learning curve in Latin American airlines.

ArtigosTechnical efficiency of Connecticut Long Island Sound lobster fishery: a nonparametric approach to aggregate frontier analysis

Natural Hazards, v. 81, pp. 1533–1548. Abstract: In this paper, we address the question whether the technical efficiency of a fishing industry is affected by the determinants of ambient water quality of the aquatic ecosystem. Using zone-specific data from 1998 to 2007 for the Connecticut Long Island Sound lobster fishery and an approach combining a bootstrapping technique with data envelopment analysis, we obtained the DEA estimates of technical efficiency for each fishing zone. We then used the bootstrapped DEA results and censored quantile regression to assess the impact of the environmental variables on different efficiency percentiles. A key result indicates when environmental conditionals are favorable (high dissolved oxygen levels), efficiency is low, and when environmental conditionals are less favorable (high levels of nitrogen), efficiency is high. The results show that the intensity of significant impacts given the contextual variables may vary among high- and low-efficiency periods.

ArtigosInfrastructure expansion in Brazilian airports: slack analysis using a distance frictionminimization approach

Decision, v. 43, n. 2, pp. 181-198. Abstract: This paper reports the use of data envelopment analysis (DEA) and a distance friction minimization (DFM) approach with fixed factors presented by Suzuki and Nijkamp (A stepwise efficiency improvement DEA model for airport operations with fixed production factors. Paper presented at the ERSA Congress. http://ideas.repec.org/p/wiw/wiwrsa/ersa11p1065.html #biblio. Accessed 18 April 2013, 2011) to assess the levels of match between expected demand for the next 25 years and infrastructure expansion investments announced by Infraero (the Brazilian Airport Authority) for the Rio de Janeiro International Airport (also known as “Galeão”). The main advantage of using the DFM approach with fixed factors lies in the fact that, to achieve maximum performance for inefficient units (away from the efficiency frontier), there is no need to linearly improve all input variables, as for most real situations, this assumption could be very difficult for management to implement and control. Additionally, this method enables the development of models with production factors that for some reason cannot be changed or adjusted by management. Based on the data regarding the planned infrastructure expansion explicit in the concession agreement for the Rio de Janeiro International Airport (established when the airport was recently privatized), the results of this study confirm those of some previous studies that had already suggested (but did not objectively measure the shortfall considering efficiency issues) a possible capacity shortfall in the medium and long run for the Rio de Janeiro International Airport.

ArtigosEnergy production in Brazil: Empirical facts based on persistence, seasonality and breaks

Energy Economics, v. 54, pp. 88-95. Abstract: This paper investigates the statistical properties of the production of energy in Brazil using long range dependence techniques in monthly data from January 2000 to February 2013. Two important features of the data are analyzed, in particular, its degree of persistence and seasonality. The results indicate first that seasonality is an essential issue in modeling the persistence in energy production. Also, the persistence itself, measured in terms of the differencing parameter is relevant, with orders of integration in the series found to be positive though smaller than 1 and thus implying mean reversion. A single structural break is also found in two of the series. Policy implications of the results obtained are also derived.

ArtigosEffectuation e a influência das redes sociais em internacionalização de startups em aceleradoras

Internext, v. 11, n. 1, pp. 63–76. Resumo: Aceleradoras recentemente se tornaram uma alternativa mais atuante do que as incubadoras como um mecanismo de apoio e desenvolvimento de startups de base tecnológica, inclusive em sua internacionalização. Ao mesmo tempo, redes sociais possibilitam e aumentam a velocidade do processo de internacionalização de pequenas firmas por meio da obtenção de recursos de terceiros e de conhecimento de mercado. Neste contexto, o objetivo desta pesquisa foi a busca de uma maior compreensão sobre como as aceleradoras agilizam o processo de internacionalização das startups nelas incubadas. Foi realizado um estudo de caso único em profundidade de uma startup de internet. A análise do processo de internacionalização da empresa teve como base teórica a abordagem do empreendedorismo internacional e a teoria de effectuation. Os resultados indicaram que a startup se beneficiou de recursos e conhecimentos obtidos por meio da aceleradora, os quais seriam comumente obtidos por meio de uma rede social. Além disso, a aceleradora, substituindo a rede social informal de maneira formal e estruturada, foi capaz de aumentar a velocidade de internacionalização da firma. A principal contribuição deste artigo é a de iluminar mais detalhadamente a conexão entre os princípios teóricos da effectuation e o uso de redes sociais na internacionacionalização de pequenas firmas.

ArtigosImpact of Introducing Full-time In-house Coordinators on Referral and Organ Donation Rates in Rio de Janeiro Public Hospitals: A Health Care Innovation Practice

Transplantation Proceedings, v. 48, n. 7, pp. 2396-2398. Abstract: Establishing an organization to promote organ donation and a good organ procurement team assure quality and improve performance on organ donation rates. Brazil’s organ procurement structure is based on 2 models disseminated worldwide: the “Spanish model,” based on in-house coordinators, and the “American organ procurement organization (OPO) model,” with extra-hospital coordinators. In 2006, Brazil’s Federal Government had formally introduced the in-house coordination model for every hospital equipped with a mechanical ventilator bed. In January 2012, the Rio de Janeiro State OPO, Programa Estadual de Transplantes, introduced an innovation in the organization of the in-house coordination model in 4 selected public hospitals with high organ donation potential. It consisted in launching full-time in-house coordination teams, with ≥1 physician and 2 nurses per hospital fully dedicated to organ procurement. The objectives were to observe the impact of this innovation in referral and organ donor conversion rates and to analyze the importance of middle managers in health care innovation implementation. Comparing the year before implementation (2011) and the year of 2014 showed that this innovation led to an overall increase in referrals—from 131 to 305 per year (+132%) and conversion rates—from 20% to 42% per year—resulting in an increase in number of donors from 26 to 128 per year (+390%). Despite wide variations among hospitals in the outcomes, our results seem very encouraging and express a positive impact of this model, suggesting that dissemination to other hospitals may increase the number of donors and transplants in our region.

ArtigosFirm age, value, performance and corporate governance in Brazil

Corporate Ownership & Control, v. 13, n. 4, pp. 8-12. Abstract: Several articles analyze the life cycle of firms and identify throughout time that their performance has an inverted U shape. Firms achieve an optimal level and, thereafter, decline due to lack of flexibility and difficulties to keep up with market changes. The objective of this study is to investigate whether there is a relation between firm age, value and performance in Brazilian companies, and we verify if firm age has an affect on their governance practices. We analyze 250 Brazilian listed firms from 2002 to 2009. Our results indicate that the relation is not shaped as an inverted U in Brazil, and that older firms show higher value and better return on their investments. We also report that older firms show better governance practices.

ArtigosWhat is the effect of banking concentration and competition on financial development? An international assessment

Journal of Economic Studies, v. 48, n. 6, pp. 1162-1176. Abstract Purpose: This paper analyzes the effect of the banking market (concentration and competition) on financial development. Design/methodology/approach: In order to estimate the effects of banking concentration and competition on financial development, we conducted an empirical analysis using the System Generalized Method of Moments (S-GMM) through a dynamic panel data model. Findings: The main results suggest that concentration and competition affect financial development. In particular, an increase in bank concentration may inhibit the country’s financial development, due to the lack of competition. Our results do not confirm the controversy between concentration and competition, suggesting that concerning financial development, concentration is the reverse of competition. Practical implications: The results of this study add a new perspective on banking market power: a financial system concentrated or uncompetitive constrains financial development. Originality/value: The literature that combines the investigation of the effects of banking market structure (concentration) and banking market conduct (competition) on financial development is scarce. Although a concentrated banking sector can reduce competition through barriers to new entrants (which could expand financial services offer), it is also true that a concentrated banking sector can be competitive. In order to avoid the controversy, our paper chooses to look into a comprehensive approach considering independent measures of bank concentration and bank competition, which together refer to the banking framework.

ArtigosCírculo Integrado de Informação: O Desafio de Integração das Polícias Civil e Militar

Revista de Administração Contemporânea, v. 26, n. 2. Resumo: Contexto: o caso narra a criação do Círculo Integrado de Informação, projeto-piloto que ocorreu em uma área circunscrita à comunidade da Rocinha, capitaneada por gestores das Polícias Civil e Militar, que foi executado por meio de parceria entre a 11ª DP – Rocinha e a 28ª UPP – Rocinha. Essa ação buscava desenvolver protocolos para a troca de informações de modo contínuo, efetivo e, sobretudo, institucionalizado entre as agências policiais locais. Entretanto, apesar de bons resultados alcançados, a iniciativa não se consolidou. Metodologia: as informações foram coletadas a partir de dados secundários e entrevistas dos gestores que participaram do processo – Dr. Gabriel Ferrando, titular da 11ª DP, e Major Felipe Carvalho Barreto, então superintendente de Inteligência da Coordenadoria de Polícia Pacificadora (CPP). Objetivos: discutir como as Polícias Civil e Militar se organizam e atuam. Resultados: desenvolvimento de análises sobre aspectos relacionados à organização e cultura das instituições policiais em relação ao tema integração. Conclusão: o caso permite compreender limites e potencialidades da integração entre as polícias, tendo por base a discussão sobre as possíveis razões de o Círculo Integrado de Informações ter sido descontinuado.

ArtigosWhat is the effect of banking concentration and competition on financial development? An international assessment

Journal of Economic Studies, v. 48, n. 6, pp. 1162-1176. Abstract Purpose: This paper analyzes the effect of the banking market (concentration and competition) on financial development. Design/methodology/approach: In order to estimate the effects of banking concentration and competition on financial development, we conducted an empirical analysis using the System Generalized Method of Moments (S-GMM) through a dynamic panel data model. Findings: The main results suggest that concentration and competition affect financial development. In particular, an increase in bank concentration may inhibit the country’s financial development, due to the lack of competition. Our results do not confirm the controversy between concentration and competition, suggesting that concerning financial development, concentration is the reverse of competition. Practical implications: The results of this study add a new perspective on banking market power: a financial system concentrated or uncompetitive constrains financial development. Originality/value: The literature that combines the investigation of the effects of banking market structure (concentration) and banking market conduct (competition) on financial development is scarce.

ArtigosUnveiling the endogeneity between social-welfare and labor efficiency: Two-stage NDEA neural network approach

Socio-Economic Planning Sciences, v. 77. Abstract: This paper estimates intersectoral labor efficiencies and its covariances in Brazil from 2003 to 2016 using a two-stage neural network model. It investigates whether there is a positive relationship between education and productivity. At the first stage, a static Markov chain regression provides labor quantitative efficiency (volume) and labor value efficiency (value added). The second stage runs a dynamic regression model between each estimated efficiency and the social contextual variables to unveil endogeneities from covariances among the variables set. Strong covariances are found between the efficiencies and fertility rate, suggesting that there is a relevant gap between the productive sector and worker qualification, leading to lower levels of efficiency in Brazil, as shown in the theoretical model. The economy is unable to allocate efficiently the stock of qualified workers.

ArtigosBuilding Bridges: Toward Alternative Theory of Sustainable Supply Chain Management

Journal of Supply Chain Management, v. 52, n. 1, pp.  82-94. Abstract: We contend that the development of sustainable supply chain management (SSCM) theory has been impaired by a lack of paradigmatic diversity in the field. The contested nature of the concept of sustainability has been repressed in SSCM theory, which has led to SSCM cutting itself off from debates that could be the source of inspiration for the development of interesting theory. We adopt the problematization approach proposed by Alvesson and Sandberg (2011) in order to unveil some of SSCM’s unquestioned assumptions, propose an alternative assumption ground, and in this way move toward stronger theory in SSCM. We use paradoxical framing to make sense of the inherent tensions between the different levels of sustainability and between the different types of theory being produced in response to the challenges of sustainability. We articulate a number of foundational assumptions for an alternative theory of SSCM that emerge from the various tensions identified between the different paradigms of sustainability. Finally, we identify a number of ideas for future research that would enable researchers to empirically explore the alternative assumptions.

ArtigosMorality and perception of corruption

Latin American Business Review, v. 22, n. 1, pp. 163-188. Abstract: Because of its very nature, corruption is hard to be measured, and thus most indices rely on people’s perception of it. However, judgments are known to be biased, and therefore perception of corruption may not reflect actual corruption. Nevertheless, how individuals perceive corruption is important: the perception that corruption is high can cause mistrust among individuals, and it may actually affect corruption. Thus, in this paper, we investigate what affects people’s perception of corruption. We find that individuals with a high moral identity internalization and those endorse the individualizing foundations of morality tend to perceive corruption to be greater.

ArtigosModelling stock market data in China: Crisis and Coronavirus

Finance Research Letters, v. 41. Abstract: Global financial markets experienced distinct collapses during the global financial crisis in 2008 and the COVID-19 pandemic in 2020, and similarity in the underlying nature is still a hot topic to be investigated. This paper investigates their degree of persistence in order to detect whether the shocks affecting them have temporary or permanent effects by examining the closing prices of the Shanghai and Shenzhen Composite Indices from 1991 to 2020. The results before the coronavirus indicate large degrees of persistence with shocks having permanent effects, while during the coronavirus the results indicate a mean reversion with shocks having temporary effects.

ArtigosSolidarity cryptocurrencies as digital community platforms

Information Technology for Development, v. 27, n. 3, pp. 524-538. Abstract: We investigate the phenomenon of solidarity cryptocurrencies by combining the societal and communitarian aspects of the traditional community currencies with the the blockchain architecture chosen in a cryptocurrency project. We classify and analyze 20 selected solidarity cryptocurrencies from different countries according to three critical aspects of solidarity cryptocurrencies: scale, territorial scope and price stability. Analysis of these aspects is critical to understand the solidarity cryptocurrency concept that connects the originally separated universes of traditional community currencies and cryptocurrencies. This paper contributes to explain the emergent solidarity cryptocurrencies phenomenon by describing particular types captured by our classification. The main findings about solidarity cryptocurrencies in this study are, first, the alignment between type of governance and the respective architecture platform; second, those with closed governance are more likely to be pegged on fiat currencies or other stable measures; third, those focused on local issues tend to have a higher level of adoption.

ArtigosVulnerability of poorly literate adult consumers regarding over-the-counter drugs

International Journal of Pharmaceutical and Healthcare Marketing, v. 15, n. 2, pp. 212-234. Abstract: Purpose: This study aims at verifying the impact of literacy on over-the-counter (OTC) drug consumer vulnerability as evaluated by health literacy and label comprehension. Design/methodology/approach: The item response theory (IRT) was used to estimate the health literacy of two groups and the two-way analysis of variance tests was used to test the hypotheses for the existence of mean differences between the two populations. The convenience sample involved 188 OTC consumers: 94 (50%) poorly literate and 94 (50%) university students/graduates. Findings: University consumers/graduates have a level of health literacy and label comprehension that is superior to those presented by poor literate consumers. Also, age does not influence the level of health literacy by OTC drug users but has a significant impact on the understanding of OTC drug labels. Finally, the level of schooling and the “age group,” simultaneously, does not impact the understanding of OTC drug labels or health literacy. Research limitations/implications: This study has added in the field of knowledge by investigating the behavior of poor literate consumers in Brazil, a developing country. The results may be relevant to Marketing professionals, especially those in the pharmaceutical industry, and to police makers, as they help identify the main problems faced by poorly literate consumers. Practical implications: It is necessary to raise awareness of the dangers of self-medication and wrong use of medications, mainly focused on people with low literacy. As a suggestion, a simple glossary presented along with the label could provide explanations of scientific terms, thus increasing health literacy and reducing the vulnerability of the consumers. Social implications: This study showed that when using common words such as gastritis to define a health problem, there is a higher degree of correctness. These results suggest the adoption of a more straightforward language and more precise explanations. By doing that, the pharmaceutical industry and policymakers will improve their social impact by increasing consumer power and taking care of the health of the most vulnerable population: the illiterate people. Originality/value: This study contributes to the international literature, as it enhances and clarifies the knowledge about the customers’ power and vulnerability in developing countries. It fills a gap by evaluating label comprehension and heath literacy at the same time, giving an academic contribution for pharmaceutical consumers’ studies.

ArtigosRisk Analysis of the Organ Donation-Transplantation Process in Brazil

Transplantation Proceedings, v. 53, n. 2, pp. 607-611. Abstract: Background: Organ transplantation has been for years one of the best treatment options for several medical conditions, and, all over the world, thousands of people need an organ transplant. However, the process through which an organ goes from a brain-dead patient to a new recipient is a complex and delicate one. Research questions: This study aims at identifying and assessing the main risks, their impact, and their relevance on the organ donation-transplantation (ODT) process in Brazil. Design: To identify and to assess the risks of the process, we interviewed coordinators at the 10 State Transplantation Centers in Brazil, which is responsible for over 90% of donations that occurred in Brazil in 2019. We applied the Failure Mode and Effect Analysis method to calculate the risks in terms of severity, occurrence, and detection. The scores obtained from each risk were used to elaborate a ranking comparing the impact of 1 risk in relation to the others. Main findings: The interviewees identified 30 risks throughout the ODT process in Brazil. Most of them are related to insufficient human and material resources, lack of staff training and commitment, and poor infrastructure or logistical aspects. Conclusions: This study complements findings from previous studies and add new risks, based on the Brazilian state coordinators’ point of view. It highlights the most critical weaknesses of the process and serves as a basis for future studies to delve deeper into each of those risks.

ArtigosNostalgia como prática? Relendo a pesquisa sobre nostalgia no campo do Marketing

Cadernos EBAPE.BR, v. 19, n. 3, pp. 524-537. Resumo: A nostalgia é um poderoso recurso de Marketing e vem apresentando novas formas e dinâmicas no cenário contemporâneo que desafiam suas interpretações clássicas. No esforço de renovar sua compreensão sobre o fenômeno do consumo, a pesquisa de comportamento do consumidor vem adotando novas ontologias, em especial aquelas orientadas a objetos. Considerando que o próprio entendimento do fenômeno do consumo vem sendo questionado, cabe questionar se as explicações atuais sobre nostalgia explicam adequadamente o fenômeno no contexto do consumo. Assim, o objetivo deste trabalho é refletir e propor novas possibilidades de investigação do fenômeno da nostalgia no campo do Marketing a partir das Teorias da Prática. O artigo apresenta duas contribuições principais: ao revisitar a literatura sobre nostalgia no campo, organiza conceitualmente as pesquisas em duas abordagens, a sentimentalista e a cultural. Por fim, o texto também reflete sobre possibilidades de releitura da pesquisa sobre nostalgia a partir das Teorias da Prática.

ArtigosSentiment analysis based on a social media customised dictionary

MethodsX, v. 8. Abstract: This article presents a methodology to classify the polarity of words from selected Tweets. Usually, social media sentiment (SMS) is lexically determined, manually or by machine learning. However, these methods are either slow or based on a pre-established dictionary, thus not providing a customised analysis. We propose a methodology that, after having mined the topic-related Tweets, filters relevant words based on the mean and standard deviation frequency in positive and negative market days to remove neutral terms. Subsequently, through an ad hoc perceptual mapping, we assign a polarity to the dataset. This method allows the building of a dictionary associated with the investor sentiment customised to that organisation. A practical application was carried out to test the proposed methodology. The results were significant and in line with the behavioural finance theory, confirming that irrational investor feelings—expressed via social media—drive a portion of asset prices. Results also confirm the investor asymmetric behaviour under gain or loss scenarios, with the latter generating more impact than the former because people are risk-averse. The proposed method is expected to identify patterns of behaviour in social media linked to market oscillations, thereby contributing to risk management and optimising decision-making in the stock market.

ArtigosImpacts of the sovereign risk perception on financial stability: Evidence from Brazil

The Quarterly Review of Economics and Finance, v. 81, pp. 358-369. Abstract: Credit Rating Agencies (CRAs) provide credit information related to sovereign bonds and play a crucial role in international financial markets. This study investigates whether CRAs sovereign credit news such as rating changes, outlook, and credit watch status affects Brazil’s financial stability as represented by credit risk and solvency risk of Brazilian banks. Using a panel with a sample of 125 banks, the results reveal that the sovereign credit news alters credit risk coverage (credit provisions) and solvency risk (capital buffer) secured by Brazilian banks. The improvement of Brazilian sovereign risk leads banks to reduce their protections against credit risk (credit provisions) and capital level, which can threaten financial stability.

ArtigosImposto de Renda nos planos da família PGBL e VGBL análise da tributação progressiva e regressiva

Revista Brasileira de Gestão de Negócios, v. 22, n. 1, pp. 388-404. Resumo: Objetivo: O estudo investiga o incentivo de tributação nos planos da família PGBL e VGBL, respondendo: qual a melhor escolha, que minimiza o Imposto de Renda, entre as opções de planos, cruzadas com os regimes progressivo e regressivo? Referencial teórico: A partir da taxonomia de incentivos tributários (Disney & Whitehouse, 1999) e efeitos econômicos (Barr & Diamond, 2009; Armstrong, Davis & Ebell, 2015), foi fundamentada a tomada de decisão individual, baseada em Sutcliffe (2016). Metodologia: Utilizamos abordagem inovadora ao calcularmos o valor presente líquido dos fluxos nominais de caixa atuarial bruto e líquido de imposto, aplicados à função objetivo que minimiza a alíquota média efetiva de Imposto de Renda, cuja definição é obtida de Fullerton (1984). Criamos um simulador para a tomada de decisão ótima de indivíduos representativos quanto ao regime tributário eleito, reduzindo, dessa forma, o valor de imposto a pagar. Implicações práticas e sociais da pesquisa: Orientamos os poupadores de PGBL e VGBL quanto à melhor decisão sobre o regime tributário e contribuímos para influenciar o aperfeiçoamento da legislação tributária. Contribuições:  O estudo traz como contribuição principal o cálculo das rendas atuariais brutas e líquidas de Imposto de Renda, impactadas pela inflação ao longo do tempo, além das variáveis tradicionalmente utilizadas, como juros reais, receitas tributáveis, despesas dedutíveis, idade, sexo e tábua biométrica.

ArtigosThe quest for a circular economy final definition: A scientific perspective

Journal of Cleaner Production, v. 314. Abstract: Circular Economy (CE) has been one of the most transformational tendencies for the past years. What seemed to be one more organizational hype, is now appearing as a global trend, affecting macro, meso and microenvironments, ranging from governments, global organizations (such as the UN), the whole private sector, science, to final consumers and individuals. Despite the numerous CE definitions, a common sense regarding what CE means is still subject of studies. This opens space for misinterpretation and misuse, as well as greenwashing and image depreciation risks. Consequently, some organizations tend to shape CE to their own definitions and paradigms rather than changing their businesses. This article builds on previous work and aims to establish a common-sense CE definition, separating it from its enablers and related concepts, which seem to be the root causes of misuse. We asked 44 worldwide CE experts PhDs the same question: “Using your own words, please describe what you understand by “Circular Economy”. Database was compiled and analysed through a coded framework and triangulated with the support of R statistical tool. The main outcome is a final definition proposal, along with a structured CE framework. It is expected this research will provide resources to allow standards organizations to establish formal cross-industry CE policies and regulations, leading to scales, targets, KPI’s development for CE assessments and audits; and guide organizations and governments on their CE transition roadmaps.

ArtigosThe cultural intertwining of consumption and entrepreneurship: A selective review of qualitative studies

Journal of Business Research, v. 135, pp. 149-162. Abstract: As technology and new business models make it easier for digital consumers to exploit what they produce, practical differences between producers-consumers and consumers-entrepreneurs become less identifiable. An analysis of existing literature shows that authors often regard this increasingly common intertwining of consumption and entrepreneurship as a unidirectional process from the former to the latter. The impact of entrepreneurship-related elements on consumption is frequently not considered. This paper uses a combination of systematic and narrative procedures to review existing interpretive consumer research literature selectively. It aims to highlight the relative importance given to entrepreneurship as an influencing factor. The Theory of Cultural Entrepreneurship (TOCE) and an energetic account of desire are used to classify selected journal articles according to a thermodynamics-inspired fourfold typology: (1) COLD-Entrepreneurship|COLD-Consumption, (2) COLD-Entrepreneurship|HOT-Consumption, (3) HOT-Entrepreneurship|COLD-Consumption, and (4) HOT-Entrepreneurship|HOT-Consumption. The review concludes by suggesting avenues for further research.

ArtigosWhy do companies engage in sustainability? Propositions and a framework of motivations

Brazilian Administration Review, v. 18, n. 2. Abstract: This article proposes a framework of corporate motivations for sustainability based on the study of sustainability engagement most prevalent in the different UN-defined macro-regions. Four main motivations were uncovered in the literature: Legitimacy — the perception that the actions are appropriate within a system of norms and beliefs; Market Success — increase in turnover, brand equity, or innovation due to sustainable practices; Process Improvement — sustainability-oriented optimization of processes; and Social Insurance — preemptive insurance against reputation or goodwill losses. Field articles were selected via a bibliometric review to develop the propositions. They indicate which motivations are of more academic concern in general and in Asia, Africa, Europe, Latin America and the Caribbean, Northern America, and Oceania. Legitimacy appears as the most prevalent motivation, followed by Market Success. More developed regions tend to have more studies on Market Success, while Social Insurance seems linked to less developed markets, where corporations must provide access to needs beyond their business.

ArtigosHow do platforms empower consumers? Insights from the affordances and constraints of Reclame Aqui

Journal of Consumer Research. Abstract: Consumer feedback platforms offer consumers tools to provide feedback on their market and consumption experiences. Beyond broad prior characterizations, little is known about the specific means by which platforms affect empowerment. Elements of empowerment identified in extant studies include voice, choice, justice, inclusion, catalysis, and consciousness-raising. We research a popular Brazilian platform to learn how platforms facilitate and constrain consumer empowerment. Our approach is immersive, a more-than-human netnography of the platform involving depth interviews with twenty-one of its consumer and corporate users. Findings show same-side and cross-side network effects driving the ability of the platform to offer consumers empowerment. Furthermore, affordances are critically important. Affordances provide opportunities for consumer choice, voice, justice, and inclusion. However, platforms’ cross-side network effects create economic considerations that limit those opportunities in theoretically and practically important ways. Although other feedback platforms might offer catalysis and consciousness-raising elements of empowerment, our focal platform does not. Earlier studies of consumer empowerment on the Internet may have been overly general and exuberant because they failed to recognize the constraining impacts of network effects, affordances, and algorithms. Consumer-citizenry, collective action, and consumer power are thoroughly transformed in the age of the platform, opening up new spaces for further investigation.

ArtigosO impacto de ativos alternativos no desempenho dos fundos de previdência privada brasileiros

Revista Contabilidade & Finanças, v. 32, n. 86, pp. 314-330. Resumo: Este artigo avalia o impacto de ativos alternativos no desempenho dos fundos de previdência privada brasileiros. Poucos estudos abordam esse tema no Brasil, abordando em sua maioria apenas a adição de ativos alternativos e seu impacto no desempenho. O mercado de fundos de previdência privada aberta no Brasil vem crescendo rapidamente nos últimos anos e ganhando notável relevância, especialmente após o anúncio da reformulação do sistema previdenciário brasileiro. Em 2018, o Plano Gerador de Benefícios Livres (PGBL) e o Vida Gerador de Benefício Livre (VGBL) representaram mais de 94% do total de ativos em seu setor. Os fundos de investimento especialmente constituídos (FIEs) dos planos de previdência privada PGBL e VGBL caracterizam-se pela sua dependência de ativos de renda fixa. O Brasil enfrenta atualmente um cenário de juros baixos sem precedentes – que, seguindo um panorama mundial, parece estar definido há muito tempo – e gestores de fundos de previdência privada devem buscar investimentos alternativos que agreguem tanto o prêmio de risco quanto a diversificação. Os resultados deste estudo podem apoiar os gestores neste assunto pouco discutido. Comparamos o desempenho dos FIEs sem ativos alternativos adicionais versus a carteira com ativos alternativos, adicionando um índice de fundo de cobertura, um índice de fundos mútuos de ações, um índice de commodities, um índice de energia elétrica, um índice de serviços públicos, um índice de ouro e um índice imobiliário. Foram utilizadas diversas medidas de desempenho, considerando as normas brasileiras e uma estratégia de reequilíbrio. Nossos resultados mostraram que quase todos os ativos alternativos utilizados neste estudo melhoraram o desempenho dos FIEs dos planos de previdência privada PGBL e VGBL, especialmente o índice de serviços públicos e o índice de fundo de cobertura. Alguns até melhoraram o risco de cauda da carteira.

ArtigosAir Pollution Assessment in China: A Novel Group Multiple Criteria Decision Making Model under Uncertain Information

Sustainability, v. 13, n. 4. Abstract: Assessment of and controlling air pollution are urgent global issues where international cooperation is deemed necessary. Although a very relevant data source can be obtained through continuous monitoring of air quality, measuring air pollutant concentrations is quite difficult when compared to other environmental indicators. We mainly have three different aims for the current study: (1) we propose the computation of the interval weights of decision makers (DMs) based on a group multiple criteria decision making (GMCDM) model; (2) we aim to rank the overall preferences of DMs by the possibility concepts; (3) we aim to evaluate the air quality in China using the most recent data based on our proposed method. We consider three monitoring stations, namely Luhu Park, Wanqingsha, and Tianhu, and the data for SO2, NO2, and PM10 are collected for November 2017, 2018, and 2019. The results from our innovative model show that November 2019 had the best air quality. Finally, robustness analyses are also performed to confirm the discriminatory power of the proposed approach.

ArtigosTowards greener petrochemical production: Two-stage network data envelopment analysis in a fully fuzzy environment in the presence of undesirable outputs

Expert Systems with Applications, v. 164. Abstract: Traditional Data Envelopment Analysis (DEA) models usually consider decision-making units (DMU) as black boxes that consume a set of inputs to produce a set of outputs and ignore the units’ internal structure. In literature, two-stage DEA models have been introduced and developed to deal with the inner workings of such DMUs; however, models in the extant literature can only be used to assess technologies with precise inputs and outputs. In this study we present an innovative two-stage DEA model for DMU evaluation in the presence of imprecise data, which are modeled using triangular fuzzy values in this study. We also innovate by including the treatment of undesirable outputs. We propose some alternative two-stage DEA network models with undesirable outputs in a full-fuzzy mode that are either directional or radial and are embedded within a multi-objective linear planning structure based on fuzzy triangular numbers. We also propose a method to solve fuzzy programming models in the presence of undesirable pollutant outputs from production processes such as greenhouse gas emissions, harmful effluents, among others. Our proposed model is then applied to a real case of 15 ammonia-manufacturing units in the Iranian petrochemical sector.

ArtigosThe home care districting problem: an application to family clinics

International Journal of Services and Operations Management, v. 39, n. 1. Abstract: There are five major issues associated with the provision of home healthcare services: facility location, districting, assignment, scheduling, and routing problems. This article investigates methods to solve home healthcare districting problems in order to improve the management of family clinic operations. Family clinic is a community healthcare centre which comprises a network of clinics staffed by a group of general practitioners and nurses providing primary healthcare services in a certain area of Brazil. The most relevant authors on this subject and the techniques most utilised to solve the districting issue are identified through a social network analysis of the authors. Finally, one of these techniques is applied to analyse its suitability for the (real) case in question, and paths are suggested to resolve territory alignment problems in the implementation of family health strategies.

ArtigosGreening inventories: Blockchain to improve the GHG Protocol Program in scope 2

Journal of Cleaner Production, v. 291. Abstract: The complexity of the supply chain, with a multiplicity of suppliers and organizations imposes challenges to its traceability, affecting the possibility of making it more sustainable. The declaration of Greenhouse Gas (GHG) by companies has been a response to pressures from stakeholders and regulations towards a sustainable supply chain management (SSCM). However, there are still some setbacks. The verification process of the inventories is a time-consuming task and the utilization of traditional renewable energy certificates can cause distortions in the perception of those who are consuming renewable energy but are not buying certificates. A blockchain-based application could address those problems by tracking transparent records of product history. Therefore, we propose a blockchain-based artifact in the form of a level 1 architecture diagram to improve the Brazil GHG Protocol Program inventory process on scope 2, which includes indirect carbon emissions from consumption of purchased electricity, heat or steam; main supply chain components. Using the Design Science Research (DSR) approach, we combine knowledge from business participants and environmental experts to understand the Program problems, propose and evaluate the artifact, and analyze its contributions. We find out that not all actors may want greater transparency in the supply chain and that traditional certificate issuers are expected to resist, while a new generation of blockchain-based certificates challenges the more traditional competitors. Additionally, the economic benefits observed in implementing blockchain points out that the organization and resistance of the actors, therefore, could be as important as costs in the implementation of new technologies in supply chains. There are two main contributions from this study. First, it introduces the discussion on blockchain adoption in the GHG Protocol Program. Second, it uses DSR as an instrument to both articulate a solution around a theoretical artifact and make its potential contribution understandable for actors not familiar with blockchain technologies. We propose that future studies could: (i) produce a proof-of-concept or a pilot implementation of this artifact; (ii) include other actors from the energy and trading certificates chain on the artifact, such as energy producers, regulators and the Brazilian Electricity Trading Chamber (CCEE); (iii) reproduce the same proposition focusing on GHG Protocol’s scope 3.

ArtigosMoeda Seeds: E-Commerce and Crypto Solutions for Development

Revista de Administração Contemporânea, v. 25. Abstract: Blockchain technology has been explored as a tool to generate social impact. An example of it is Moeda Seeds, a Brazilian ecosystem operating to support financial inclusion and gender equality, two UN sustainable development goals, by facilitating access to microfinance for female entrepreneurs with social impact projects. Traditionally facing difficulties to access credit in the traditional banks, the selected Seed Projects are also granted with management support from Moeda’s ecosystem to optimize its entire chain efficiency and helping them to promote long-term sustainable practices for the local communities to thrive. This whole ecosystem is enabled by a blockchain-based payment and lending platform and Moeda’s proprietary digital tokens, which people around the world can promptly and transparently invest while participating in sustainable growth. This teaching case brings the COVID-19 crisis as background panorama and the founder Taynaah Reis in the center of an urgent strategic decision-making process. It covers the difficulties, variables, and alternatives presented to structure a contingency plan during that period of high uncertainty. It is extended by the teaching notes, covering: social cryptocurrencies, blockchain, digital platform, online sales, network externalities, and e-commerce ecosystem.

ArtigosA New Hybrid Fuzzy Model Satisfaction of Residents in Touristic Areas toward Tourism Development

Mathematical Problems in Engineering, v. 2021. Abstract: This research brings a practical approach to the issue of the level of satisfaction from residents in tourist destinations by using three attractive methods together. After reviewing the theoretical foundations and the meta-synthesis method in identifying indicators, fuzzy Delphi was used for screening, fuzzy SWARA (stepwise weight assessment ratio analysis) for weighting, and fuzzy EDAS (evaluation based on distance from average solution) for 16 very important tourism areas in Iran. Six important factors (economic, cultural, environmental, perceptual, social, and health) along with 42 important criteria were identified in the meta-combination method, while also obtaining the total weight of the indicators. Finally, the sensitivity analysis of the model is performed and practical suggestions presented.

ArtigosAn original information entropy-based quantitative evaluation model for low-carbon operations in an emerging market

International Journal of Production Economics, v. 234. Abstract: Drawing on the mixed results provided by the existing literature on low-carbon operations management practices, this paper proposes an original evaluation model for CO2 emission reduction practices in Brazil, based on the concept of information entropy. We model the information entropy of different low-carbon operations management practices, such as logistics, manufacturing processes and new product development. Then, in light of the role of stakeholder pressures, motivations and barriers, we take a novel approach to assessing the relative importance of elements of the model by using information entropy to develop probabilistically distinctive weightings for low-carbon managerial practices, computed using a variety of models. These models include (a) the Fuzzy Rasch model, which combines Item Response Theory (IRT) and fuzzy set theory; (b) the Fuzzy AHP (Analytic Hierarch Process) model; and (c) the crisp AHP model, based on eight different judgment scales concerning the relative evolution of each criterion/construct. Our results, both expected and unexpected, suggest that: (i) there is heterogeneity in the ways that different companies perceive the issue of low-carbon practices; (ii) while the firms studied are motivated to reduce CO2 emissions and such reduction is required by various stakeholders, the reduction is implemented solely through low-carbon logistics. Unexpectedly, we find that companies are not adopting a full-range of low-carbon operations practices, which may damage their overall performance. Implications for end-users and policy makers are highlighted.

ArtigosRisk Analysis of the Organ Donation-Transplantation Process in Brazil

Transplantation Proceedings, v. 53, n. 2. Abstract:
Background: Organ transplantation has been for years one of the best treatment options for several medical conditions, and, all over the world, thousands of people need an organ transplant. However, the process through which an organ goes from a brain-dead patient to a new recipient is a complex and delicate one. Research questions: This study aims at identifying and assessing the main risks, their impact, and their relevance on the organ donation-transplantation (ODT) process in Brazil. Design: To identify and to assess the risks of the process, we interviewed coordinators at the 10 State Transplantation Centers in Brazil, which is responsible for over 90% of donations that occurred in Brazil in 2019. We applied the Failure Mode and Effect Analysis method to calculate the risks in terms of severity, occurrence, and detection. The scores obtained from each risk were used to elaborate a ranking comparing the impact of 1 risk in relation to the others. Main findings: The interviewees identified 30 risks throughout the ODT process in Brazil. Most of them are related to insufficient human and material resources, lack of staff training and commitment, and poor infrastructure or logistical aspects. Conclusions: This study complements findings from previous studies and add new risks, based on the Brazilian state coordinators’ point of view. It highlights the most critical weaknesses of the process and serves as a basis for future studies to delve deeper into each of those risks.

ArtigosSustainable efficiency drivers in Eurasian airports: Fuzzy NDEA approach based on Shannon’s entropy

Journal of Air Transport Management, v. 92. Abstract: This research explores the physical infrastructure and flight consolidation efficiency drivers of Eurasian airports regarding their infrastructure and movement productivity levels. A novel Fuzzy Double-Frontier Network DEA (FDFNDEA) model is proposed to investigate the relationship between desirable (freight and passenger turnovers) and undesirable (pollutant emission levels due to aircraft movements) outputs against the respective infrastructure usage, fuel consumed, and movements performed at each of the 23 Eurasian airports from 2000 to 2018. This balance between desirable and undesirable outputs emerges spatially and temporally due to the evolution of the airport system’s productive resources at each one of the Eurasian countries over the period observed. Shannon’s entropy is used as the cornerstone to quantify the input and output vagueness of this evolution in Triangular Fuzzy Numbers (TFN), thus allowing the accurate building of alternative optimistic and pessimistic double-frontier efficiency. Differently from previous research, Shannon’s entropy is the key for measuring input and output vagueness levels in light of the maximal entropy principle. This principle states that the distribution that best represents the current state of knowledge is the one with largest entropy. Maximal entropy yields bias-free decision-making in the sense that the input/output distributional profiles for Eurasian airports contain the maximal possible heterogeneity, working as a robust or best/worst-case scenario against eventual unconsidered assumptions. Hence, optimistic and pessimistic Malmquist Productivity Indexes (MPI) for overall and each stage productivity results are subsequently regressed against contextual variables related to airport characteristics and regional socio-demographic and economic indicators of each Eurasian country using bootstrapped Cauchy regressions. The findings revealed the spatial heterogeneity of productivity factors and airport performance across Eurasia. Results also demonstrated the negative impact of income inequality and the positive impact of private participation on technological progression in the Eurasian airport industry.

ArtigosThe First Year of Mandatory Comply-or-Explain in Brazil

Latin American Business Review, v. 22, n. 1, pp. 1-32. Abstract: The law mandated Brazilian companies to comply or explain to a corporate governance code from 2018. This article analyzed 1,720 unique explanations of non-compliance for 43 recommended practices from 108 companies and developed a taxonomy of explanations and adherence quality indices. Most firms did not explain deviations properly, resorting frequently to generic and uninformative explanations. Firm size and performance were positively and ownership concentration and market risk negatively associated with adherence indices. State-owned companies displayed greater adherence. This evidence is robust to changes in index methodology that did not consider the quality of explanations and challenges the effectiveness of the comply-or-explain requirement.

ArtigosThe Rio’s transport legacy: pre- and post-Games resident perceptions

International Journal of Sports Marketing and Sponsorship, v. 22, n. 1, pp. 32-52. Abstract: Purpose: The Rio 2016 Olympic Games required a significant investment in the public transport systems, connecting four city’s areas and providing different types of impacts and legacies for their hosts. The purpose of this paper is to examine resident perceptions of the public transportation issues in the Rio host city before and after the Games. Key factors underpinning transportation issue outcomes are identified. Design/methodology/approach: Data were collected among Rio local residents by using a pre-Games (n = 504) and post-Games design (n = 421). The cross-sectional and longitudinal data were assessed at both time periods. An exploratory factor analysis revealed five factors, and a confirmatory factor analysis analysed the psychometric properties of the constructs proposed. Subsequently, MANOVA and a series of ANOVA tests (one-way and paired samples) were performed to analyse the differences in perceptions before and after the Games. Findings: Results revealed a five-factor model of public transportation issues perceived: planning, infrastructure, insecurity, information and urban mobility. Resident perceptions for four factors (planning, infrastructure, insecurity, urban mobility) increased from pre- to post-Games, meaning that they have a more negative perspective about those issues. In contrast, the findings suggested an improvement in public transport information perceived between the period before and after the Games. Originality/value: This study contributes to the academic literature related to discussing the Olympic legacy by providing evidence of how hosting the Olympics may lead to social exchange with negative outcomes on transport legacy. The findings of this study can be used as valuable information for future event organizers, local authorities and governments.

Computer Methods and Programs in Biomedicine, v. 205. Abstract: The aim of this study is to present a new methodology to explore a field of research and exercise this technique to find good mathematical models to solve the problem of territorial alignment applied to health services. For this purpose we show a methodology that combines three methods of analysis: social network analysis, longitudinal analysis, and mapping change analysis. In this paper, we applied the mapping change method, originally used in large networks, to small and medium ones, and used the Tabu search scheme instead of simulated annealing. Finally, to highlight the significant changes over time of keywords networks, an alluvial diagram is used to show the significance clusterings through the subperiods studied. The work reports on the most relevant authors on the subject and the most widely used mathematical models applied to solve the problem.

ArtigosThe impact of alternative assets on the performance of Brazilian private pension funds

Revista Contabilidade & Finanças, v. 32, n. 86, pp. 314-330. Abstract: This article assesses the impact of alternative assets on the performance of Brazilian private pension funds. Few studies touch on this topic in Brazil and most only investigate the addition of alternative assets and their impact on the performance. The market of open private pension funds in Brazil has been growing rapidly in recent years and gaining much relevance, especially after the announcement of the reformulation of the Brazilian pension system. In 2018, the Free Benefit Generating Plan (PGBL) and the Free Benefit Generating Life (VGBL) represented more than 94% of total assets in their sector. The Brazilian specially constituted investment funds (FIEs) of PGBL and VGBL private pension plans are characterized by their dependence on fixed income assets. Brazil currently faces an unprecedent low interest rate scenario – which, following a worldwide panorama, seems to be set for a long time – and pension fund managers must search for alternative investments that aggregate both risk premia and diversification. The results of this study may support managers in this little-discussed matter. We compare the performance of FIEs without additional alternative assets versus the portfolio with alternative assets, adding a hedge fund index, an equity mutual funds index, a commodity index, an electric power index, a public utilities index, a gold index, and a real estate index. Several performance measures were used, considering Brazilian regulations and a rebalancing strategy. Our results showed that almost all alternative assets used in this study improved the performance of the Brazilian FIEs of PGBL and VGBL private pension plans, especially the public utilities index and the hedge fund index. Some even improved the portfolio tail risk.

ArtigosRecent activism initiatives in Brazil

International Journal of Disclosure and Governance, v. 15, n. 1, pp. 40-50. Abstract: This study offers an overview of shareholder activism in Brazil through the mapping of various types and examples of activism, the construction of an activism index and an analysis relating the activism index to corporate characteristics. Investor engagement and activism may be an important driver of corporate governance improvement (Gillan and Starks in J Appl Finance 13(2):4–22, 2003; Chung and Zhang in J Financ Quant Anal 46(1):247–273, 2011). Activism is more often found in: larger companies; those with many shareholders; with inferior corporate governance practices; and controlled by the state. The study documents the increase in the average activism index during the period, with only eight companies failing to register any type of activism event. However, the items comprising the index did not develop in a homogeneous fashion, with some remaining stable, while others decline. The indicators with the highest rates of growth during the period were: minority presentation of proposals at shareholder meetings; cumulative voting requests to elect directors; and the number of news articles related to the topic. The sample contains 195 companies listed on the Brazilian stock exchange and observed in 2008, 2010 and 2012. The hand-collected data come from minutes of ordinary and extraordinary shareholder meetings, complaints filed with the securities commission and news articles published in a daily business newspaper. The article contributes to the literature on corporate governance in emerging markets and offers a rare view of thousands of shareholder assembly events in one large developing country, being of interest to practitioners and regulators in other emerging economies.

ArtigosInsolvency of Brazilian electricity distributors: A DEA bootstrap approach

Technological and Economic Development of Economy, v. 24, n. 2, pp. 718–738. Abstract: This study investigates the financial and operational indicators that explain the insolvency of Brazilian electricity distributors, using a data envelopment analysis (DEA) bootstrap approach.The Wagner and Shimshak (2007) stepwise procedure was used to select the variables that had the greatest impact on average efficiency estimated by DEA in the construction of an inefficient frontier. Through a second stage analysis, the Simar and Wilson (2007) bootstrapped truncated regression analyzed contextual variables associated with inefficiency, and consequently with firm insolvency. The sample was composed of electricity distributors, whose financial information for the 2000–2015 period was available on the Brazilian Securities Exchange (CVM) website. The results indicated that the Actual Equivalent Frequency of Power Interruptions/Regulatory Equivalent Frequency of Power Interruptions and Overall Indebtedness were the most important indicators in explaining insolvency. The second-stage analysis showed that the inefficiencies calculated using the selected indicators are positively related to insolvency criteria used by the literature, state control, dollar and geographical location, and negatively related to the domestic inflation index. The results provide valuable information for the Brazilian electricity sector’s regulatory body, which recently began to hold public hearings prior to setting up procedures for monitoring financial sustainability using financial and operational indicators.

ArtigosIslamic banking and performance in the asean banking industry a TOPSIS approach with probabilistic weights

International Journal of Business and Society, v. 18, S1, pp. 129-150. Abstract: This paper uses an integrated two-stage approach to assess the performance of 88 ASEAN (Association of Southeast Asian Nations) banks from 2010-2013. The relative importance of different financial ratios that emulate the CAMELS rating is collected using the expert opinions of 88 ASEAN bank managers with the help of a structured questionnaire. The computation of empirical joint probabilities is used first to derive weights for a number of criteria related to Capital adequacy, Asset quality, Management quality, Earnings, Liquidity, and Sensitivity to market risk. In the second stage, these weights are used as TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) inputs to assess the relative efficiency of ASEAN banks. The results reveal the prominent role of Islamic principles in banking efficiency. More specifically, these beneficial results are found when banks are private. We then use our results to develop policy recommendations.

ArtigosFuzzy inference systems and inventory allocation decisions: Exploring the impact of priority rules on total costs and service levels

Expert Systems with Applications, v. 85, pp. 182-193. Abstract: Inventory allocation decisions in a distribution system concern issues such as how much and where stock should be assigned to orders in a supply chain. When the inventory level of an inventory point is lower than the total number of items ordered by lower echelons in the chain, the decision of how many items to allocate to each “competing” order must take into consideration the trade-off between cost and service level. This paper proposes a decision-support system that makes use of fuzzy logic to consider inventory carrying, shortage and ordering costs as well as transportation costs. The proposed system is compared through simulation with three other inventory allocation decision support models in terms of cost and service levels achieved. Conclusions are then drawn.

ArtigosA structural vector autoregressive model of technical efficiency and delays with an application to Chinese airlines

Transportation Research Part A: Policy and Practice, v. 101, pp. 1-10. Abstract: This study reports on the performance assessment of Chinese airlines from 2006 to 2014 using a stochastic distance function where technical efficiency and a measure of flight delays follow a joint structural autoregressive process. This model is used to investigate whether technical efficiency causes flight punctuality or the other way around. The model, however, yields a non-trivial likelihood function and is not amenable to estimation using least squares or standard maximum likelihood techniques. To estimate the model therefore, we propose and implement maximum simulated likelihood with importance sampling. The results suggest a mutual dependence (feedback) between technical efficiency and delays. Policy implications are derived.

ArtigosContrato psicológico e a influência de redes sociais: um estudo de caso com jovens profissionais

Revista de Administração da Unimep, v. 15, n. 1, p. 128-154. Resumo: O presente trabalho desenvolveu uma perspectiva conjunta de dois temas de interesse para o estudo do comportamento organizacional: contrato psicológico e redes sociais. O principal objetivo desta pesquisa foi analisar o contrato psicológico e a influência da rede social e dos relacionamentos interpessoais na percepção de um grupos de funcionários, em relação aos termos de seu contrato psicológico com a sua empresa. A pesquisa é qualitativa, baseada em um estudo de caso único. A empresa pesquisada tem sede nos Estados Unidos, está presente em mais de 170 países, e é uma referência entre as grandes empresas de tecnologia da informação do mundo. A filial brasileira faz parte de um modelo de negócios que utiliza o conceito de Centros de Serviços Compartilhados ou Centros de Excelência. Estes têm o objetivo de atrair profissionais mais qualificados, garantindo custos competitivos e a padronização dos processos. O estudo foi realizado com uma das equipes que trabalham no Centro de Excelência brasileiro. Um grupo de 19 funcionários participou deste estudo. A coleta de dados ocorreu na própria empresa e o principal método utilizado foi a entrevista em profundidade. A rede de informação, relacionada a informações sobre o contrato psicológico, também foi mapeada e mensurada com o auxílio dos softwares Ucinet (BORGATTI; EVERETT; FREEMAN, 2002) e Netdraw (BORGATTI, 2002). Os resultados do programa Ucinet demonstraram que a densidade da rede foi de 14,3%, diâmetro de 5 ligações e distância média de 2,07 entre cada par de atores. Além disso, apenas um clique foi encontrado – um subgrupo coeso onde todos os três integrantes se nomearam mutuamente (KILDUFF; TSAI, 2003). Com relação aos conectores centrais, o gestor (E14), apesar do considerável nível de inserção, não parece ter um grande potencial de influência social. Nesse sentido, o gestor da equipe não se apresenta como fonte essencial na influência do contrato psicológico. As fontes de influência mostram-se dispersas na rede. Os resultados da pesquisa sugerem que existe uma grande possibilidade de contágio social, especialmente entre funcionários mais novos, na ausência de uma estratégia de comunicação clara entre a organização e seus funcionários. Com base na definição de Janssens et al. (2003), os contratos psicológicos observados são categorizados como fracos, com obrigações mutuamente fracas. Com isso, a análise mostrou que o contrato coletivo, normativo (ROUSSEAU, 1995), é mais relevante no contexto analisado do que os contratos psicológicos individuais. A pesquisa comprovou a influência dos relacionamentos interpessoais na percepção individual de um contrato psicológico, especialmente diante de um contrato psicológico fraco.

ArtigosCultural resonance of global brands in Brazilian social movements

International Marketing Review, v. 34, n. 4, pp. 480-497. Abstract: Purpose: The research analyzes the presence of two global brands – Fiat and International Federation of Association Football – in Brazilian demonstrations in conjunction with the 2014 World Cup. The purpose of this paper is to extend the brand cultural resonance construct and highlights its boundary-straddling nature. The analysis reveals the dynamics of brand meanings established including why some brands have their meanings enriched through collective appropriation, while others become vessels of negative content and targets of anti-consumption movements.

Design/methodology/approach: A multimethod approach, which included observation, analysis of cultural texts and in-depth interviews with 21 demonstrators, was adopted for the study.

Findings
The study extends the construct of brand cultural resonance proposing an additional facet, named Institutional Resonance. This dimension relates to the meanings that arise from a brand’s institutional role and interactions with other social institutions, like governments, the economy, religious, and educational systems. Institutional Resonance occurs when a certain brand becomes the archetypal representation of a social institution. This study also presents two forms of brand cultural resonance: arrows or targets. As arrows, brands lend their symbolic resources to the construction of protesters’ messages helping them to communicate their ideas. As targets, brands become social enemies and represent negative poles of social contradictions.

Originality/value: This study investigates consumer appropriation of marketers’ actions. The research depicts Institutional Resonance as an interactive and acute phenomenon which promotes a social negotiation on a playing field where different agents forge brand meanings and reputations.

ArtigosCentralidade do trabalho na perspectiva de mulheres em diferentes faixas etárias

Revista de Administração, Contabilidade e Economia, v. 16, n. 1, pp. 9-36. Resumo: No presente estudo descreve-se a centralidade do trabalho na perspectiva de mulheres brasileiras, com nível superior, de diferentes faixas etárias (20 a 29 anos, 30 a 39 anos, acima de 40 anos) e que trabalham em empresas privadas na Cidade do Rio de Janeiro. Este é um estudo qualitativo em que se utilizou a análise de conteúdo como método de pesquisa e teve-se como principal fonte de dados a entrevista em profundidade. A análise foi realizada em torno da dimensão centralidade do trabalho, que consiste na importância absoluta (valor atribuído ao trabalho dentro da vida do indivíduo) e relativa (valor atribuído a ele se comparado a outras esferas da vida, como família, amigos, lazer e religião, entre outras) do trabalho na vida de uma pessoa (MOW, 1987). Na pesquisa identificou-se que o trabalho remunerado é uma atividade central e importante na vida das entrevistadas. No entanto, verificou-se também que a relação afetiva e temporal com o trabalho passa por mudanças ao longo do tempo. À medida que as entrevistadas vão adquirindo maior maturidade e experiência, elas repensam suas prioridades e procuram, efetivamente, em maior ou menor medida, conciliar o trabalho com outras esferas de suas vidas. A maternidade parece contribuir significativamente para que desejem estabelecer novas dinâmicas cotidianas, podendo participar ativamente da criação de seus filhos e da rotina familiar.

ArtigosAs organizações e a felicidade no trabalho: uma perspectiva integrada

Revista de Administração Contemporânea, v. 21, n. 6, pp. 764-787. Resumo: A despeito do grande número de estudos relacionados à felicidade derivada do trabalho nas organizações, estes são dispersos, divergentes e, portanto, pouco conclusivos. Isto traz dificuldades para a evolução da pesquisa sobre este tópico e para a tomada de decisões no dia a dia quanto ao tema nas empresas. Tomando por base uma revisão de literatura abrangente, este artigo propõe uma perspectiva que engloba o conhecimento desenvolvido sobre o assunto até o momento. Para tanto, parte de três questões: como se define felicidade no trabalho; o efeito da felicidade no trabalho nos resultados das empresas; e o que torna os indivíduos felizes no trabalho. A proposta de perspectiva integrada utiliza os princípios de Kahneman e Riis (2005), concentrando-se principalmente nos antecedentes da felicidade no trabalho e seus possíveis impactos no comportamento do indivíduo na organização.

ArtigosAtravessando sinais fechados: Negociações de gênero no consumo brasileiro de automóveis

Revista Interdisciplinar de Marketing, v. 7, n. 2, pp. 194-207. Resumo: Se por um lado, autores discutem a relação íntima entre o automóvel e sua função expressiva na condição masculina de gênero, por outro, é frequente a publicação na mídia de pesquisas que apontam a crescente importância da mulher no processo de decisão de compra do automóvel familiar. A categoria de automóveis projeta um espaço favorável para discutir o encontro de práticas e significações de consumo masculinas e femininas, que, ao serem investidas sobre o mesmo produto, geram um cenário turbulento e enriquecedor. O objetivo deste trabalho foi investigar a construção de práticas e narrativas de consumo em espaço de litígio de gênero, onde homens e mulheres adotam o mesmo mercado como recurso para a formatação de suas identidades de gênero particulares e opostas. Foram realizadas entrevistas em profundidade (RJ e MG) e grupos de discussão com homens e mulheres. Propomos o conceito de arena de gênero, definido como o espaço de consumo, que apresenta marcações identitárias específicas, oferecendo uma nova camada de interpretação da questão de gênero, no encontro entre objeto e indivíduo. A construção de identidades de gênero adotam recursos simbólicos e materiais, mas se desenrolam em espaços que filtram e redefinem essas mensagens.

ArtigosOs efeitos da identificação regional no valor da marca do patrocinador esportivo

REAd – Revista Eletrônica de Administração, v. 23, n. 3, p. 116-146. Resumo: Desde que foi escolhido como sede da Copa do Mundo de 2014 e dos Jogos Olímpicos de 2016, o montante de receitas movimentado pelo patrocínio esportivo no Brasil têm crescido significativamente, entretanto, sem que a prática gerencial e a pesquisa acadêmica tenham se desenvolvido no mesmo ritmo. O presente estudo, que visa contribuir para o avanço do conhecimento sobre tema, investigou o impacto da identificação regional do patrocinador e da congruência entre time e patrocinador no valor da marca do patrocinador. As principais referências teóricas do estudo são a teoria da identidade social (TAJFEL; TURNER, 1979), a teoria do esquema (AXELROD, 1973), a teoria da rede associativa (COLLINS; LOFTUS, 1975) e o valor da marca na perspectiva do consumidor (KELLER, 1993). A pesquisa foi realizada em Porto Alegre, capital do Rio Grande do Sul (RS), estado marcado pela valorização da cultura regional gaúcha. A amostra foi não-probabilística, composta por 2.116 fãs de Grêmio e Internacional. Foi analisada a relação entre os dois times as marcas Banrisul e a Unimed Porto Alegre, patrocinadoras de ambos os clubes há mais de dez anos. A análise dos dados foi realizada utilizando a Análise Fatorial Exploratória e Análise Fatorial Confirmatória; e foram verificados a confiabilidade e as validades convergente, discriminante e nomológica dos construtos. Para testar as hipóteses substantivas, foi aplicada a Modelagem de Equações Estruturais, usando a técnica ADF. Os resultados empíricos sugerem que o valor da marca do patrocinador é influenciado principalmente de forma indireta pela identificação regional do patrocinador, dado que este efeito é mediado parcialmente pela congruência entre time e patrocinador.

ArtigosThe Internationalization Journey of a Multiplex Cinema Company under the Lens of Different Behavioral Theories

International Business Management, v. 11, n. 6, pp. 1157-1168. Abstract: This study goes through the relevant organizational behavioral theories regarding the internationalization of companies, taking a Mexican multiplex cinema company as a case study. The main objective of this research was to analyze and compare different theories with a real life situation in order to determine the usefulness of each theory and to what degree they have an impact under different circumstances of a company’s internationalization process. The theories used in the analysis were the uppsala model, international entrepreneurship, effectuation theory and network approach. The analysis led to the conclusion that there is no single theory that sustains throughout all of the internationalization process of a company but that rather, all theories are complementary to each other.

ArtigosExchange Options in the REIT Industry

Advances in Investment Analysis and Portfolio Management, v. 9. pp. 217-252. Abstract: This article models mergers as exchange options where acquirers offer stocks and/or cash to target firms in exchange of acquiring some shareholding in target firms. Mergers analysed in this article happen between homogeneous entities. The Black and Scholes (B–S) and Margrabe models are used to price cash and stocks (including stocks and cash) deals respectively. The merger and acquisition (M&A) traits are grouped as conflict of interest, market growth, funding and specialization. Regression results illustrate that exchange options react to M&A characteristics differently. Thus, the results are beneficial to both sell-and buy-side investors in terms of how one manages merging firms. The goodness of fit suggests that strategic acquisitions played important roles.

ArtigosContext and Theorizing in the Global South: Challenges and Opportunities for an International Dialogue

BAR – Brazilian Administration Review, v. 16, n. 3. Brazilian researchers have been encouraged to internationalize their research, expanding their insertions into high impact international journals. This task in turn demands thinking outside the commonly used Eurocentric prism. How can Brazilian scholars say something that would be of interest globally and have an impact on the work done in the global North? How should the researcher from the global South deal with context in the international dialogue to avoid being perceived as the exotic Other? This interview with professor Guliz Ger addresses these and other important issues related to the challenge of theorizing and publishing research from a global perspective. Professor Ger’s work inspires Brazilian researchers in their internationalization efforts by offering concrete examples of how to theorize, strategies to overcome editors’ and journals’ prejudices and convince the international audience of the value of global South, and more particularly, Brazilian research. Professor Ger’s experience as a visiting professor in numerous universities around the world including in Brazil, and her service on a number of journal editorial boards, including the Journal of Consumer Research, for which she served as Associate Editor, provided the background for this interview produced by Maribel Suarez and Thaysa Nascimento.

ArtigosDo foreign portfolio capital flows affect domestic investment? Evidence from Brazil

International Journal of Finance and Economics, v. 24, n. 2, pp. 855-883. Abstract: Although there are several direct and indirect theoretical channels through which foreign capital flows may affect domestic investment, empirical evidence remains inconclusive. In this paper, we employ a VARX framework to assess the impact of equity foreign portfolio investment (EFPI) on domestic investment growth, employing monthly series for the Brazilian economy. Our results suggest that EFPI played a nonnegligible role in explaining aggregate investment fluctuations, but only before the 2008 global financial crisis. After the crisis, a period marked first by a shift in economic policy in 2008–2009, with substantial increases in government intervention, followed by deterioration in the institutional outlook and political stability in 2014–2015, mostly against the backdrop of the Petrobras corruption scandal, unexpected shocks to EFPI no longer led any real effects on investment growth. Although, in general, our results vouch for beneficial effects of equity capital flows on investment, this virtuous relationship is likely disturbed by interventionist policies and political unrest.

ArtigosEnsino e pesquisa de marketing: A pílula vermelha como alternativa

RAE-Revista de Administração de Empresas, v. 59, n. 5, pp. 365-369. Pensanta. Meu primeiro artigo apresentado em congresso foi um ensaio teórico, embora tenha sido advertida de que só trabalhos empíricos eram selecionados. Não sei quem foram os revisores, mas com certeza eram professores que gostaram ou entenderam minhas aflições sobre os desafios de pensar e ensinar Marketing (Casotti, 1995). Tenho aqui a oportunidade de refletir novamente sobre quão desafiante e instigante continuam sendo o ensino e a pesquisa de Marketing. A disciplina tem ampliado a importância do seu papel, que já foi visto como predominantemente instrumental. O consumo de bens, serviços, ideias e tudo mais envolve, além da organização de empresas produtivas de naturezas diversas, complexas relações de mercado e muitos acordos sociais.

ArtigosPensando na Aposentadoria: PGBL, VGBL ou Autoprevidência?

Revista Brasileira de Risco e Seguro, v. 16, n. 24, pp. 19-46. Resumo: O presente trabalho teve por objetivo analisar os planos de previdência privada aberta no Brasil, em especial os planos conservadores, do tipo PGBL e VGBL (que investem 100% dos seus recursos em renda fixa). Este estudo é o primeiro a realizar cálculos segundo o rígido arcabouço legal e atuarial do sistema previdenciário brasileiro vigente. Suas análises são pioneiras e importantes. Com uma pesquisa de campo que abordou as quatro maiores seguradoras do Brasil, condições de mercado praticadas foram mapeadas e um cenário-base foi construído realisticamente. Não obstante o fato de taxas de carregamento e de administração serem maiores em planos previdenciários, constatou-se que, no longo prazo, o plano PGBL ainda é bastante compensatório, devido aos benefícios fiscais, podendo acumular de 21% a 32% além de um fundo tradicional. Já o plano VGBL, quando comparado a fundos de renda fixa (estratégia de autoprevidência), pode não ser vantajoso se a taxa de administração cobrada for da ordem de meio ponto percentual maior ou se a rentabilidade anual líquida média for da mesma ordem, menor. Já na fase de recebimento de renda, dadas as taxas oferecidas atualmente pelas seguradoras pesquisadas, concluímos contundentemente que a aposentadoria por um plano PGBL ou VGBL não é atrativa. Neste caso, de forma até interessante, a melhor estratégia seria uma política adequada de resgates periódicos desses planos (uma solução mista de autoaposentadoria por um plano de previdência). A principal conclusão deste trabalho é que o mercado de previdência privada aberta precisa se tornar mais eficiente e competitivo para atingir os seus objetivos primordiais.

RAE-Revista de Administração de Empresas, volume 58, n. 1, p. 96-97, 2018. Book Review: When Tom Farley took office as Commissioner of the New York Health Department in 2009, replacing Thomas Frieden, he felt like “taking over as manager of the Yankees after they had won the World Series seven years in a row.” Farley took the helm of a successful change started by Frieden in the centenary New York City Department of Health and Mental Hygiene, created in 1866 with responsibilities from street cleaning and sanitary permits to fight against infectious diseases, such as cholera and yellow fever.

ArtigosBranded retailer expansion on a continent-sized emerging market

International Journal of Retail & Distribution Management, v. 46, n. 9, pp. 820-834. Abstract Purpose: The purpose of this paper is to identify patterns for the intra-market expansion of international branded retailers on a continent-sized emerging market using the network approach. Design/methodology/approach: A multiple-case study design of four foreign branded retailers that have expanded onto regional markets in Brazil is used. Findings: The intra-market expansion process shares similarities with the cross-market expansion process; is influenced by the relationships of foreign branded retailers with local competitors and shopping mall firms; and market selection, mode of operation and store location decisions are interrelated and conjointly taken, instead of forming a three-stage process. Additionally, the importance of relationships with host market shopping malls firms is highlighted. Research limitations/implications: This paper advances a conceptual model of the intra-market expansion process, which comprises a system of interrelated decisions – (regional) market selection, mode of operation and store location – influenced by several network effects. Practical implications: Managers of foreign branded retail suffer from liability of foreignness when undertaking intra-market expansion. Although Brazil is a large market, the retail community is highly connected because of managers’ personal relationships. Brazilian shopping malls dominate suitable store locations, and represent a valuable source of knowledge and resources for the foreign branded retailer.
Originality/value: This paper addresses two under-researched aspects of international retail: branded retailers – manufacturers that develop brands and operate stores – and intra-market expansion (i.e. to geographic regions of a given foreign country). It also discusses the challenges of intra-market expansion in continent-sized emerging markets, with considerable regional diversity (culture, infrastructure and institutions).

ArtigosBayesian bid updating in experimental IPO pricing methods

Revista de Finanças Aplicadas, v. 9, n. 1, pp. 84-104. Abstract: This article investigates bid updating and subject learning in experimental initial public offers (IPO) of stock pricing methods. A clock auction stands for the “Dutch auction”. A sealed-bid uniform price auction represents “book building”. A two-stage “book building” emulation represents a recent innovation called “competitive IPO”. The literature addresses investor learning in a single method from actual bidding data in Taiwan. Investor IPO bidding is commonly private information and one needs to employ experiments to analyze investor behavior. Rational or Bayesian updating takes place when investor performance improves in successive bids. Naive reinforcement or updating means that subjects bid influenced by their success in previous biddings, with little consideration of the information available. The experimental “book building” led to gains more often. The evidence in the updating analysis suggests that learning occurs according to Bayesian updating and not to naive updating in “book building” and is consistent with it being the most common IPO method around the world.

ArtigosO corpo nos estudos de consumo: Uma revisão bibliográfica sobre o tema

Consumer Behavior Review, v. 1, pp. 32-48. Resumo: O objetivo do artigo é compreender como o corpo tem sido investigado nos estudos de consumo, ao longo dos últimos 42 anos no Journal of Consumer Research. Além de ser um elemento muito valorizado na cultura brasileira, sendo até apontado como uma forma particular de capital, o corpo movimenta uma grande indústria de produtos e serviços. Visando fornecer subsídios a futuros pesquisadores de estudos de consumo, os autores realizaram levantamento bibliográfico, pela leitura de 79 artigos do tema publicados no JCR, sendo selecionados 45 que abordavam direta ou indiretamente o tema corpo e complementados por artigos nacionais. Os autores concluem inicialmente que se deu a exploração de sua estrutura biológica, ou de caracteres mais tangíveis, e posteriormente, foram reconhecidos e explorados seus aspectos simbólicos e subjetivos. São propostas diferentes abordagens paradigmáticas e metodológicas como possíveis linhas investigativas para estudos futuros.

ArtigosRepresentações sociais do cigarro na cultura popular brasileira

Revista Interdisciplinar de Marketing, v. 7, n. 1, pp. 26-41. Resumo: O artigo investiga a representação do cigarro no imaginário coletivo brasileiro, enfatizando a dimensão simbólica do seu consumo. A partir de abordagem qualitativa e interpretativista, analisa 15 entrevistas em profundidade com ex-fumantes e 45 músicas do repertório contemporâneo brasileiro. O trabalho destaca a associação do cigarro com os temas de vício e fraqueza, mas alerta para outros significados culturais que podem ampliar a atratividade do produto, como transgressão, rebeldia, capacidade de resistência, companhia e consolo. A pesquisa chama atenção para a importância de se compreender os significados que estão sendo gerados pelos textos culturais, sobretudo aqueles de maior apelo junto ao público jovem. O trabalho aponta ainda para caminhos complementares para as campanhas de prevenção ao consumo e estímulo ao abandono do cigarro, que podem ser enriquecidas por uma perspectiva multidimensional, que inclua não apenas as dimensões orgânica e cognitiva, mas contemple também os aspectos sociais e simbólicos relacionados a esse consumo.

ArtigosBank efficiency in Saudi Arabia: examining the impact of the global financial crisis

Central European Review of Economics and Management, v. 1, n. 4, pp. 69-86. Abstract: Aim: The global financial crisis in 2008 has obstructed almost every bank around the world. This study examines the impact of global financial crisis on bank efficiency in Saudi Arabia. Design / Research methods: This study examines the impact of global financial crisis in bank efficiency applying the data envelopment analysis (DEA) during 2006-2014. Eleven commercial banks were examined from Saudi banking sector which covers almost half of total banks of Saudi Arabia. Scale efficiency, technical efficiency and productivity of banks have been examined for assessing the impact of financial crisis overtime. Conclusions / findings: Results reveal that banks in Saudi Arabia are inefficient in terms of technical and scale efficiency. The results also reveal these banks are not immune to the global financial crisis. Though only one bank has kept their unit efficient positions during the study period, the impact of global crisis on bank efficiency is found visible among other banks. The robustness of this study is also tested. Originality / value of the article: The importance of this study is twofold. First, examining bank efficiency with special attention to financial crisis. Second, Saudi Arabia needs sustainable growth to be ensured. Hence, examination of impact of financial crisis on bank efficiency of Saudi Arabia will surely help the policy makers for future planning

ArtigosEficiência técnica e inovatividade: um estudo em hospitais privados brasileiros

Revista Sistemas & Gestão, v. 12, n. 4, pp. 410-421. Resumo: Os hospitais têm procurado melhorar seu desempenho e a inovatividade tem sido destacada como um aliado nessa missão. O objetivo da pesquisa foi verificar se a percepção de inovatividade dos gestores de hospitais está relacionada com o desempenho de suas organizações. A inovatividade foi definida como uma medida da capacidade da empresa de inovar e foi operacionalizada mediante variáveis relacionadas à inovatividade organizacional e à inovatividade percebida da firma. O desempenho foi definido pela eficiência do hospital em utilizar os recursos disponíveis para prestar serviços. Os resultados de um survey, realizado com gestores de 20 hospitais privados pertencentes a maior operadora de planos de saúde do Brasil, mostraram que a inovatividade percebida possui relação inversa com a eficiência técnica: quanto maior a capacidade ou propensão da empresa a inovar, tanto percebida pela cultura interna da organização quanto por sua forma de atuar no mercado, menor a eficiência técnica do hospital.

ArtigosBusiness, government and foreign policy: Brazilian construction firms abroad

Brazilian Political Science Review, v. 11 , n. 1. Abstract: This article analyses the interaction between Brazilian companies and government in the context of foreign policy, observing the state’s support for the internationalization of large Brazilian civil construction firms. The results show that over the years these companies had privileged access to the Federal Executive, including civil service agencies. One consequence of this system of channelling demands through the Executive was to demote the Legislative branch to a secondary role. This pattern of interaction changed following the restoration of Congress’s decision-making capacity, prompting the sector to diversify its areas of influence, focusing in particular on the Congress. To expand internationally, construction firms interact with the government primarily through the Executive, specifically via the Ministry of Foreign Affairs (Itamaraty), which provides technical and diplomatic support, and the Banco Nacional de Desenvolvimento Econômico, which supplies funding. The main argument of this article is that foreign policy should be examined through the relations between state and non-state actors in a multitude of decision-making arenas, taking into consideration both domestic and international factors.

ArtigosJoining the sociomaterial debate

Revista de Administração de Empresas, v. 57, n. 6, pp. 536-541. Abstract: We are at Paris-Dauphine University on a warm afternoon of May 2011. A small group of scholars and PhD students are currently occupying two rooms to start a new and informal experience together. Their wish is to create an occasion for discussing, from a multidisciplinary perspective, a number of emergent topics and their interconnection with technology and practices “in the context of organizing.” Among the emergent topics, some terms appear prominent, like material, materiality, sociomateriality, and performativity. This first meeting sowed the seeds for the launching of a series of annual workshops under the name OAP: Organizations, Artifacts, and Practices. The purpose of this introductory article is to present the OAP community to the RAE readers in order to initiate a dialogue and eventually integrate Latin American voices in the so-called materiality turn. As the ninth OAP workshop will take place in São Paulo in 2019, this encounter is timely.

Cadernos Gestão Pública e Cidadania, v. 22, n. 72. Resumo: O artigo tem o objetivo de analisar os direcionadores para a atuação dos diferentes modelos institucionais do microcrédito produtivo no Brasil. Utiliza-se o modelo “multinível” a fim de investigar a relação entre os interesses e processos de negociação entre os grupos envolvidos no microcrédito. O estudo empírico inclui um banco público, uma Sociedade de Crédito ao Microempreendedor e à Empresa de Pequeno Porte (Scmepp), e uma Oscip de microcrédito. Os resultados mostram que o foco na gestão da implementação da metodologia do microcrédito produtivo orientado é condicionante para atingir bons resultados. Parcerias com órgãos governamentais, bem como a participação das instituições de microcrédito nos processos de políticas públicas, são um grande desafio e potencial para o aprimoramento do setor de microcrédito.

ArtigosFactors affecting desire to negotiate again

Journal of Managerial Psychology, v. 32, n. 1, pp. 16-29. Abstract Purpose: The purpose of this paper is to investigate the effects of negotiation process and outcome on an individual’s desire to negotiate again with the same counterpart. Design/methodology/approach: Data were collected from 115 dyads representing two companies negotiating an eight-issue property leasing agreement via e-mail. Desire to negotiate again was regressed on demographic/personality, process, and outcome measures. Findings: Reaching an agreement was found to be significantly related to desire to negotiate again, while the number of messages exchanged and the mean number of competitive tactics employed were positively and negatively associated with reaching an agreement, respectively. Further, perceived honesty of self and counterpart were also associated with an individual’s desire to negotiate again. Originality/value: This study focuses on an aspect of real negotiations often overlooked by researchers – the likelihood of future encounters with the same party – and examines three categories of factors that could affect a party’s desire to negotiate with a counterpart again – demographic/personality, process, and outcome (actual and perceived).

Revista de Administração Contemporânea, v. 21, n. 6, pp. 811-831. Resumo: Este artigo revela o perfil de internacionalização dos pesquisadores brasileiros no campo de Administração de Sistemas de Informação (ADI) com base em análise de três dimensões: Formação, Disseminação de pesquisa e Colaboração em redes internacionais. Baseado na coleta de dados provenientes da Plataforma Lattes, Google Scholar e dos websites das instituições de ensino, referente a um total de 554 pesquisadores com doutorado completo, um grupo de 50 pesquisadores brasileiros neste campo foi identificado com algum grau de inserção internacional. Este estudo revela que os pesquisadores mais internacionalizados do campo são majoritariamente provenientes de instituições das regiões Sudeste (66%) e do Sul (28%) do País. Apenas uma parcela (16%) desses pesquisadores realizou doutorado no exterior, embora outros tenham tido experiências internacionais por intermédio de pós-doutorado (38%), cursos de extensão (45%) ou bolsa sanduíche (18%). A Disseminação internacional dos trabalhos deste grupo de pesquisadores cresceu 65% no período entre 2010 e 2015, com publicação em periódicos e participação em congressos internacionais. A rede de Colaboração internacional deste grupo de pesquisadores também foi identificada na pesquisa.

ArtigosEfficiency in Nigerian airports

Case Studies on Transport Policy, v. 5, n. 4, pp. 573-579. Abstract: This paper analyzes efficiency levels in Nigerian airports using a stochastic frontier model that captures the impact of unobserved managerial ability during the period 2003–2014 based on the methodology presented in Alvarez et al. (2004) – the AAG model. Managerial ability in Nigerian airports is an important issue for sustaining efficiency levels because they are labor intensive rather than capital-intensive facilities. The AAG model was modified in this research to measure two exogenous contextual variables, namely regulation and hub. Under this modified version of the AAG model, inputs and outputs are disentangled in the frontier estimate while simultaneously allowing these contextual variables to control the impacts of managerial ability on efficiency. Results not only suggest that variations in efficiency scores are more sensitive to labor than to capital costs, but also indicate a negative impact of regulation and hub operations on efficiency levels possibly due to the small operational scale of Nigerian airports. Policy implications are derived.

ArtigosNévoas, vapores e outras volatilidades ilusórias dos cigarros eletrônicos

Cadernos de Saúde Pública, volume 33, supl. 3. Resumo: Neste artigo, analisa-se o discurso de fornecedores de cigarros eletrônicos para convencer potenciais usuários (fumantes, ex-fumantes ou nunca fumantes de cigarros) a adquirir e usar o novo produto. É um estudo qualitativo, descritivo e exploratório acerca do discurso de vendedores em oito sites de venda on-line que, entre 2011 e 2013, tiveram maior frequência de buscas na Internet. Os sites foram identificados pela ferramenta Google Trends, com base no número de acessos e frequência de buscas ao tema cigarro eletrônico. Tendo como referencial metodológico a hermenêutica-dialética, a categorização do material empírico sob o esquema “compreensão/interpretação” apontou quatro abrangentes sentidos: apropriação do discurso antitabagista; comparação entre cigarros convencional e eletrônico; apelo à crença na fidedignidade da ciência; e projeção da imagem do cigarro eletrônico. A análise desses sentidos configurou os elementos argumentativos do discurso de posicionamento de marketing utilizado por fabricantes e fornecedores de cigarros eletrônicos.

ArtigosBank efficiency in Malaysia: a use of malmquist meta-frontier analysis

Eurasian Business Review. v. 7, pp. 287–311. Abstract: This paper uses a two-stage data envelopment analysis to examine bank efficiency in Malaysia. In the first stage, we use meta-frontier technology to address bank heterogeneity-bank nature (Islamic vs. conventional banks) and bank ownership (local vs. foreign banks). Using a data set of 43 Malaysian commercial banks, the application of meta-frontier enables us to compare the existence of inefficiency among Malaysian banks because of their business nature and ownership. In doing so, we empirically demonstrate that using different approaches (i.e., production, profitability, and intermediation) for calculating bank efficiency can give significant contradictory results in efficiency scores. In the second stage, we use Simar and Wilson’s double bootstrap regression to estimate the determinants of efficiency in Malaysian banks. This helps to achieve valid inference even in the presence of unknown serial correlation in the meta-frontier efficiency scores. The results from double bootstrap regression confirm that bank ownership, bank nature and gross domestic product have significant influence on bank efficiency. This study reveals that Islamic banks have outperformed. The frontier results reveal that local Islamic banks have moved towards the group technology and foreign Islamic banks have taken the lead in country frontier technology.

ArtigosFinancial access and interest rate spread: An international assessment

Journal of Economics and Business, v. 114. Abstract: The present study evaluates the hypothesis that countries where banks expand financial access through branches and ATM networks have smaller interest rate spreads. To do so, the financial access index produced by the International Monetary Fund was used to capture financial access through bank branches and ATMs (automated teller machines). Through a data panel analysis of 68 countries during the period between 2006 and 2015, the results of this study indicate that the bank interest rate spread is lower in countries with greater financial access. However, this effect is decreasing, indicating a limit to the effect on the spread.

ArtigosCultural tensions in lean healthcare implementation: A paradox theory lens

International Journal of Production Economics, v. 233. Abstract: The purpose of this research is to use a paradox theory lens to investigate in greater depth how to manage cultural tensions in a healthcare organisation implementing lean. Conducting an in-depth single case study at a private specialized hospital, we classify cultural tensions according to the four categories proposed by paradox theory – namely learning, organizing, belonging and performing. Our study scrutinizes the role of the dimensions of organisational culture (OC) as antecedents to both defensive mechanisms (i.e. resistance to change) and managerial actions (lean practices). From a theoretical perspective, this research offers key implications. We expose a nuanced view of how different OC traits may act as either drivers or barriers to lean implementation. In addition, we show how lean practices act as managerial actions that can help mitigating defensive mechanisms and thus help managing the four types of paradoxes. We also offer a specific discussion of the paradox of learning, previously missing in prior studies of lean. From a managerial perspective, the study offers a guide to managers dealing with cultural resistance that naturally emerges during lean implementations. To the best of our knowledge, no previous study has explored the interplay of lean implementation and OC using a paradox theory lens.

ArtigosEffects of citizen participation in the social accountability of budget amendments

The Journal of Legislative Studies, v. 27, n. 1, pp. 30-54. Abstract: The paper investigates two Brazilian legislative innovations called Participatory Amendments to analyse their effects on electoral connection and on the social accountability of public budgeting. Previous studies have focused on participatory mechanisms in local governments and mainly on the formulation phase of public budgeting. Thus, we aim to fill this theoretical gap by exploring the case of two initiatives designed by congressmen that use direct participation to modify the current modus operandi of deciding and monitoring individual parliamentary amendments to the budget bill. Our results showed that these initiatives changed the decision-making process in terms of power of actors and quality of projects, while increasing the electoral connection, and can mitigate some accountability traps by amplifying voice and by sharpening teeth, especially if associated with capacity-building programmes and monitoring mechanisms.

ArtigosHotel Performance in the UK: The Role of Information Entropy in a Novel Slack-Based Data Envelopment Analysis

Entropy, v. 23, n. 2, pp. 184. Abstract: Previous hotel performance studies neglected the role of information entropy in feedback processes between input and output management. This paper focuses on this gap by exploring the relationship between hotel performance at the industry level and the capability of learning by doing and adopting best practices using a sample of 153 UK hotels over a 10-year period between 2008–2017. Besides, this research also fills a literature gap by addressing the issues of measuring hotel performance in light of negative outputs. In order to achieve this, we apply a novel Modified slack-based model for the efficiency analysis and Least Absolute Shrinkage and Selection Operator to examine the influence of entropy related variable on efficiency score. The Results indicate that less can be learnt from inputs than from outputs to improve efficiency levels and resource allocation is more balanced than cash flow and liquidity. The findings suggest that market dynamics explains the cash flow generation potential and liquidity. We find that market conditions are increasingly offering the opportunities for learning and improving hotel efficiency. The results report that the distinctive characteristic of superior performance in hotel operations is the capability to match the cash flow generation potential with market opportunities.

ArtigosEvaluation model of competitive and innovative tourism practices based on information entropy and alternative criteria weight

Tourism Economics, v. 27, n. 1, pp. 23-44. Abstract: An evaluation model of competitive and innovative tourism practices in Portugal based on information entropy is proposed. The relative evolution of each criterion/construct is explored in the light of its predictability/randomness in Portuguese companies by calculating and analysing the information entropy of different perceptions on competitive and innovative tourism practices. This article presents a novel approach by using information entropy to handle probabilistically different competitive and innovative practice weights computed by alternative models such as (a) the Fuzzy Rasch model that combines the item response theory and the fuzzy set theory, (b) the fuzzy analytic hierarchy process (AHP) model and (c) the crisp AHP model based on eight different judgment scales on the relative evolution of each criterion/construct. The results show that the total information entropy suggests a strong heterogeneity in Portuguese companies in terms of innovation for competitiveness. They also reveal a significant relationship between innovative tourism practices and tourism competitiveness models.

ArtigosAn exploration of eLearning adoption in the educational ecosystem

Education and Information Technologies, v. 26, pp. 585–615. Abstract: Teaching and learning processes have not experienced major changes during the last centuries. However, eLearning platforms may transform these processes, turning the classroom from a teacher-centered and standardized space into a student-centered, customizable and highly scalable environment. These changes impact many different stakeholders such as parents, teachers, universities, software developers and textbook publishers. Therefore, to fully understand the adoption process of an innovation such as eLearning, using traditional technology adoption models that center on a single stakeholder (the end-user) may not be enough. Perspectives from multiple stakeholders must be considered. These stakeholders may come from different industries that make up an ecosystem. Hence, this study aims to explore eLearning adoption through an ecosystem perspective. In order to do so, 58 in-depth interviews were conducted with representatives from 6 different ecosystem stakeholders in the Brazilian higher education ecosystem. Using discourse analysis, the study identified 10 general constructs that simultaneously influence distinct stakeholders in the Brazilian higher education ecosystem in their intention to adopt eLearning.

ArtigosA generalized fuzzy Multiple-Layer NDEA: An application to performance-based budgeting

Applied Soft Computing, v. 100. Abstract: Network data envelopment analysis (NDEA) is capable of considering operations and interdependence of a system’s component processes to measure efficiencies. There are numerous performance evaluation applications in which some indicators have hierarchical structures with a considerable number of sub-indicators. This problem of ignoring the hierarchical structure of indicators weakens the discrimination power of NDEA models and may result in inaccurate efficiency scores. In this paper we propose a generalized fuzzy Multiple-Layer NDEA (GFML-NDEA) model and GFML-NDEA-based composite indicators (GFML-NDEA-CI) to incorporate the hierarchical structures of indicators in the ambit of the particular two-stage NDEA models. To demonstrate the usefulness of the GFML-NDEA-CI model proposed, its application was tested by evaluating the efficiency of the performance-based budgeting (PBB) system in 14 governmental agencies in Iran. The comparative analysis results obtained from the GFML-NDEA-CI (multi-layer) model with those from the single-layer fuzzy NDEA-CI model indicate that the number of efficient decision-making units (DMUs) in the one-layer model is eight, whereas it is solely one DMU in the multi-layer model. The discrimination power of the multi-layer model proposed is significantly increased by observing that standard deviation of efficiency scores are increased by 41%, 61%, and 84% for possibility levels 0, 0.5, and 1, respectively. This is obtained while reducing information entropy, thus suggesting that the proposed model yields more reliable scores.

ArtigosCash holdings and profitability of banks in developed and emerging markets

International Review of Economics & Finance, v. 71, p. 880-895. Abstract: We examine the effect of cash holdings on bank profitability using a worldwide database. Unlike previous studies, we model it as a non-monothonic relationship. We consider as a proxy for banks’ profitability the return on equity and the return on assets. Our results show that there is a non-monotonic relationship between the cash conversion cycle and bank profitability. Also, we show that banks in emerging markets (BRICS) hold more cash than banks in developed countries (G7). Moreover, our results reveal an increase in the banks’ cash holdings after the 2008 financial crisis.

ArtigosTowards greener petrochemical production: Two-stage network data envelopment analysis in a fully fuzzy environment in the presence of undesirable outputs

Expert Systems with Applications, v. 164. Abstract: Traditional Data Envelopment Analysis (DEA) models usually consider decision-making units (DMU) as black boxes that consume a set of inputs to produce a set of outputs and ignore the units’ internal structure. In literature, two-stage DEA models have been introduced and developed to deal with the inner workings of such DMUs; however, models in the extant literature can only be used to assess technologies with precise inputs and outputs. In this study we present an innovative two-stage DEA model for DMU evaluation in the presence of imprecise data, which are modeled using triangular fuzzy values in this study. We also innovate by including the treatment of undesirable outputs. We propose some alternative two-stage DEA network models with undesirable outputs in a full-fuzzy mode that are either directional or radial and are embedded within a multi-objective linear planning structure based on fuzzy triangular numbers. We also propose a method to solve fuzzy programming models in the presence of undesirable pollutant outputs from production processes such as greenhouse gas emissions, harmful effluents, among others. Our proposed model is then applied to a real case of 15 ammonia-manufacturing units in the Iranian petrochemical sector. The promising results that we obtained in our research and their implications for theory and practice are then presented and discussed.

ArtigosPrincipal-principal conflicts leading to activism of a large government-owned investor in Brazil

Corporate Governance and Organizational Behavior Review, v. 5, n. 1, pp 15-21. Abstract: This article analyzes conflicts between principals that led to activism by one large Brazilian government-owned investor as a minority shareholder and verifies the antecedents, means employed, apparent motivations, and effectiveness of its reactions (Goranova & Ryan, 2014). It examines the cases of three large high ownership concentration listed companies using solely public sources. Poor performance was a frequent conflict antecedent. No evident trade-off between activism and corporate governance (CG) practices emerged. High ownership concentration influenced the way the investor reacted and its success because opposition through internal CG mechanisms was usually not successful and led to legal proceedings. The limitations of the regulatory framework became evident from the mixed outcomes of these proceedings. The investor was not exclusively financially motivated and it occasionally opposed the interests of other minority shareholders to follow government policy. These findings illustrated how high ownership concentration rendered difficult the mitigation of principal-principal conflicts even for a large government-owned investor and help explain the failure of previous econometric studies to relate activism, quality of CG practices and performance (Young, Peng, Ahlstrom, Bruton, & Jiang, 2008).

ArtigosThe firm-investor level characteristics of institutional investor engagement in Brazil

International Journal of Disclosure and Governance, v. 17, pp. 267–281. Abstract: The degree and form of engagement of a particular institutional investor, its potential alignment with management, and the stability and duration of its stock holdings vary with the investee company. This article scores each firm–investor stock holding pair considering various engagement characteristics simultaneously and investigates their impact on the corporate governance practices in a panel of Brazilian companies between 2013 and 2016. Research about institutional investors activism in emerging markets is still scarce according to Claessens and Yurtoglu (Emerg Mark Rev 15(1):1–33, 2013), who claim that institutional investors may be more concerned about avoiding abuse from controlling shareholders than trying to monitor them, leading to a potential contrast with their behavior in developed countries. The results show that asset managers engage less than other institutional investors and that there was no significant impact of engagement on corporate governance when firm–investor pair level and company-aggregated institutional investor scores are used. Examination of individual items of the score indicates that being a board member and signatory of shareholders’ agreement is associated with worse corporate governance practices, suggesting that investors are probably aligned with management when they occupy insider positions. Institutional investors that hold stable and long-term equity stakes and foreign ones are related to better corporate governance practices. Minority shareholders should not construe the presence of institutional investors, particularly the domestic ones, as evidence of strong external corporate management monitoring in emerging markets.

ArtigosCritical success factors for sustainable entrepreneurship in Pakistani Telecommunications industry: a hybrid grey systems theory/ best-worst method approach

Management Decision, v. 58, n. 11, pp. 2565-2591. Abstract Purpose: This study focuses on the Critical Success Factors (CSF) for developing sustainable entrepreneurship in the Pakistani telecommunication industry. Despite the efforts made by governments and stakeholders to stimulate sustainable entrepreneurship initiatives, contributions in the telecommunications sector are lacking. Therefore, this study has the major objective of identifying a transformation path for these firms. This is done by providing a theoretical framework for sustainable entrepreneurship in the telecommunications industry, focusing on managerial and operational practices that should be modified according to a set of CSFs identified by experts in Pakistani firms.

Design/methodology/approach: This article proposes a novel Multiple Attribute Decision Making (MADM) approach based on Grey Systems Theory (GST) and Best-Worst Method (BWM) while unveiling endogenous relationships among current managerial/operational practices and the CSFs for sustainable entrepreneurship in the telecommunications industry.

Findings: CSFs for achieving sustainable entrepreneurship in the Pakistani telecommunications industry were found to rely on a tripod, based on effectiveness, transparency, and accountability that are embedded within the ambit of managerial and operational practices, such as focusing and reducing digital illiteracy, targeting poor communities, helping the young in structuring start-ups.

Originality/value: This article contributes to the MADM research stream by proposing a novel use of the BWM technique based on GST to promote sustainable entrepreneurship CSFs in Pakistani telecommunications firms.

Journal of Enterprise Information Management, v. 33, n. 5, pp. 1059-1076. Abstract Purpose: The purpose of this paper is to analyze demand forecast strategies to support a more sustainable management in a pallet supply chain, and thus avoid environmental impacts, such as reducing the consumption of forest resources. Design/methodology/approach: Since the producer presents several uncertainties regarding its demand logs, a methodology that embed zero-inflated intelligence is proposed combining fuzzy time series with clustering techniques, in order to deal with an excessive count of zeros. Findings; A comparison with other models from literature is performed. As a result, the strategy that considered at the same time the excess of zeros and low demands provided the best performance, and thus it can be considered a promising approach, particularly for sustainable supply chains where resources consumption is significant and exist a huge variation in demand over time. Originality/value: The findings of the study contribute to the knowledge of the managers and policymakers in achieving sustainable supply chain management. The results provide the important concepts regarding the sustainability of supply chain using fuzzy time series and clustering techniques.

ArtigosHospital accreditation impact on healthcare quality dimensions: a systematic review

International Journal for Quality in Health Care, v. 32, n. 8, pp. 531–544. Abstract Purpose: To systematically review the impact of hospital accreditation on healthcare quality indicators, as classified into seven healthcare quality dimensions. Data source: We searched eight databases in June 2020: EBSCO, PubMed, Web of Science, Emerald, ProQuest, Science Direct, Scopus and Virtual Health Library. Search terms were conceptualized into three groups: hospitals, accreditation and terms relating to healthcare quality. The eligibility criteria included academic articles that applied quantitative methods to examine the impact of hospital accreditation on healthcare quality indicators. Study selection: We applied the PICO framework to select the articles according to the following criteria: Population—all types of hospitals; Intervention—hospital accreditation; Comparison—quantitative method applied to compare accredited vs. nonaccredited hospitals, or hospitals before vs. after accreditation; Outcomes—regarding the seven healthcare quality dimensions. After a critical appraisal of the 943 citations initially retrieved, 36 studies were included in this review. Results of data synthesis: Overall results suggest that accreditation may have a positive impact on efficiency, safety, effectiveness, timeliness and patient-centeredness. In turn, only one study analyzes the impact on access, and no study has investigated the impact on equity dimension yet. Conclusion: Mainly due to the methodological shortcomings, the positive impact of accreditation on healthcare dimensions should be interpreted with caution. This study provides an up-to-date overview of the main themes examined in the literature, highlighting critical knowledge-gaps and methodological flaws. The findings may provide value to healthcare stakeholders in terms of improving their ability to assess the relevance of accreditation processes.

ArtigosService innovation in healthcare: a systematic literature review

Latin American Business Review, v. 21, n. 4, pp. 353-369. Abstract: In recent decades, healthcare innovation improvements in product technology, treatments, and care delivery have successfully increased patient life expectancy and quality of life, and made access to care, treatments, and diagnostic-path options easier. Innovation in healthcare is also generating efficiency, reducing costs and human errors. Due to this bivalent behavior, innovation is playing a fundamental role in the healthcare ecosystem scenario. With a growing focus on innovation, interaction among healthcare actors is constantly increasing and improving care outcomes, providing a more personalized care, and bringing a new way to provide and co-create value. This study presents a systematic literature review, seeking to analyze and summarize the evidence regarding how service innovation in healthcare is promoting personalized care solutions and how the increasing interaction between healthcare actors is generating new ways to co-create value.

ArtigosProducing beauty ‘the hard way’: Involuntary prosumption in a stigmatising context

Journal of Marketing Management, v. 36, n. 13/14, pp. 1223-1251. Abstract: Traditionally, the literature indicates that consumers have acted as prosumers voluntarily and for hedonic or leisure motivations. Only a few studies contend that consumers engage in prosumption activities forcibly because of social or material constraints. Through 15 in-depth interviews and complementary secondary data, the present research aims to outline an involuntary form of prosumption and investigate its formation. Findings show that consumers are socially and ideologically convoked to become prosumers, even at times against their will, learning ‘the hard way’ how to produce. Our theoretical contribution lies in delineating involuntary prosumption in a context marked by stigma, social invisibility, and market constraints.

ArtigosGenetic services diffusion in the precision medicine ecosystem

International Journal of Pharmaceutical and Healthcare Marketing, v. 14 n. 4, pp. 533-560. Abstract: Purpose: Genetic knowledge is advancing steadily while at the same time DNA sequencing prices are dropping fast, but the diffusion of genetic services (GS) has been slow. The purpose of this paper is to identify GS diffusion drivers in the precision medicine (PM) ecosystem. Design/methodology/approach: After reviewing the literature on innovation diffusion, particularly on GS diffusion, the PM ecosystem actors are interviewed to obtain their perspective. Using content analysis, the interviewees’ visions were interplayed with the literature to achieve driver conceptualization, which posteriorly originated broad themes. Findings: The results indicate that GS diffusion depends on satisfying aspects from three broad themes and respective drivers: technology (evidence strength and credibility, customization, knowledge, data and information, tech evolution speed and cost), human (ethics, privacy and security and user power) and business (prevention, holistic view of the individual, public policy and regulation, business model and management). Practical implications: The main management implications refer to considering health care in a multidisciplinary way, investing in the propagation of genetic knowledge, standardizing medical records and interpreting data. Originality/value: This study, to the best of authors’ knowledge, is the first attempt to understand GS diffusion from a broad perspective, taking into account the PM stakeholders’ view. The 13 drivers offer a comprehensive understanding of how GS could spread in health care and they can assist researchers and practitioners to discuss and set strategies based on an initial structured map.

ArtigosA decision-support approach under uncertainty for evaluating reverse logistics capabilities of healthcare providers in Iran

Journal of Enterprise Information Management, v. 33, n. 5, pp. 991-1022. Abstract Purpose: This paper aims to assess and prioritize manufacturing companies in the healthcare industry based on critical success factors (CSFs) of their reverse logistics (RL). The research involves seven medical device companies located in the Tehran Province, Iran. Design/methodology/approach: To identify and prioritize companies based on CSFs of RL, the study proposes a three-phase decision-making framework that integrates the Delphi method, the best-worst method (BWM) and the Additive Ratio Assessment (ARAS) method with Z-numbers. The weights required for this method are obtained by a variant of the BWM based on Z-numbers, denoted as Z-numbers Best-Worst Method, or ZBWM. Since decision-makers face an uncertain environment, Z-numbers, which are a kind of fuzzy numbers, are applied. Findings: First, after customizing CSFs by the Delphi method and obtaining 15 CSFs of RL, these are ranked by the hybrid BWM-ARAS method with Z-numbers. Results reveal which company appears to perform best with respect to their RL implementations. Based on this result, healthcare device companies should choose the highest priority company based on the selected RL CSFs and results from using the BWM-ARAS method with Z-numbers. Originality/value: The contribution of this paper is using a hybrid ARAS-BWM method based on Z-numbers. Each of these methods has some merits compared to other similar methods. The combination of these methods contributes a new approach for prioritizing companies based on RL CSFs with high accuracy and reliability.

ArtigosAgglomeration economies and university program creation in the knowledge

Socio-Economic Planning Sciences, v. 72. Abstract: Existing academic literature on the relationship between agglomeration economies and university activities is both under-theorized and relatively sparse in terms of empirical examination. This paper addresses each of these voids by contributing and analyzing a market model of pro-revenue education program creation such as graduate-level executive business education (e.g. EMBA) that reveals some intriguing characteristics. For instance, it shows that demand for these pro-revenue programs is inelastic and therefore uniquely determines their availability. More specifically, we show that through agglomeration economies these types of education programs are more likely to emanate from universities located in metropolitan areas and from less academically prestigious universities. Regression analysis of a cross-section of national public universities lends support to important facets of our formal model by suggesting that agglomeration economies continue to increase the probability of offering EMBA programs through a city size of approximately 2.12 million and that the probability that a given business school will offer an EMBA is negatively related to the academic prestige of the institution to which it is affiliated.

ArtigosSelection of stock funds using information that is not observable or measurable

Revista Contabilidade & Finanças, v. 32, n. 85. Abstract: The aim of this paper is to investigate whether the flows and the future returns of stock funds are related to investors’ unobservable information. This article extends the knowledge about investment decisions regarding stock funds and considers a representation of unobservable information that until now has not been contemplated by the Brazilian literature. Understanding decisions to invest in stocks has become more important since the fall in interest rates and migration toward equity investments. The use of unobservable information for making investment decisions is important when choosing stock funds and the return gap could be added to the list of information offered to investors. The return gap measures the value added by managers in relation to the most recently disclosed complete lagged portfolio and was calculated every month for every asset in the portfolios of every fund in the sample disclosed with a three-month lag. A parsimonious sample was used of 22 actively managed funds in the period from January of 2010 to December of 2018, containing one from every one of the 22 biggest independent Brazilian managers, because it is laborious to calculate this metric. The return gap represents unobservable information about a fund. Investors that direct their capital toward stock funds with a higher historical return gap tend to obtain higher returns in out-of-sample tests, suggesting persistence of the returns of these funds and supporting the importance of unobservable information. Investors that directed their capital toward funds with lower historical return gaps could also obtain positive alphas in some cases, indicating that some managers were neglected. The fund flow results were inconclusive.

ArtigosUnveiling the endogenous relationship between technical efficiency and value creation in mergers and acquisitions in Nigeria

South African Journal of Economics, v. 88, n. 1, pp. 40-70. Abstract: There is a growing literature on how the beneficial impacts of horizontal mergers and acquisitions (M&A) should be measured. Thus far, however, there have been few studies addressing endogeneity between technical efficiency and value creation: they tend to present a bidirectional and simultaneous relationship. This research contributes to the debate by investigating the impact of voluntary horizontal M&A on these metrics in Nigeria between 1995 and 2012, in light of the individual performance of bidders, targets, and the resulting corporate companies. First, technical efficiency, technology gap ratio, and returns‐to‐scale estimates were computed based on a meta‐frontier DEA approach, together with a set of contextual variables that encompass performance indicators which reflect the value creation process. Then, robust regressions were used to discriminate these efficiency estimates in terms of such business‐related variables, correcting for endogeneity and controlling for industry and trend effects. The results reveal that these contextual variables significantly impact virtual efficiency and returns‐to‐scale levels, and that there is a trade‐off between efficiency and value creation at some point in the merging process. Managerial implications are derived.

ArtigosA Sociotechnical Approach of eGovernment in Developing Countries: An Analysis of Human Development Outcomes

International Journal of Systems and Society, v. 3, n. 1. Abstract: In the context of Information and Communication Technology (ICT) for development (ICT4D) the capability approach raises questions about the best way to generate human development outcomes through governments’ implementation of ICT, encompassing specific demands of the people. Considering that quality of working life was an emergent value for the sociotechnical supporters and could foster human development, this perspective can also be used to explain the use of ICT in government. This research proposes a conceptual model to explain how governments’ implementation of ICT contributes to improved human development through a sociotechnical perspective and its alignment with users’ needs and expectations. The contribution of this study is the extending of the ICT4D research in a sociotechnical view and its impact in human development. By including the social context in the model, it emphasizes the differences between countries in different levels of development, the differences between users’ demands and the differences in human development outcomes.

ArtigosExperimenting, partnering and bonding: a framework for the digital influencer-brand endorsement relationship

Journal of Marketing Management, v. 36, n. 11/12, pp. 1009-1030. Abstract: Endorsement studies have gained complexity with the possibilities created by social media platforms, where ordinary consumers can achieve celebrity status and rise to the level of digital influencers. Recent studies highlight that influencers have evolutionary trajectories. However, little is known about how these trajectories are related to social media endorsement dynamics. Based on a five-year netnography, this research investigates the main forms of endorsement that connect digital influencers and brands and how endorsement practices evolve along influencers’ trajectories. The research outlines three forms of endorsement relationship that evolve during the influencer’s career cycle: experimenting, partnering and bonding. Finally, the paper argues that brands play different roles, as providers, partners and hirers, supporting and rewarding digital influencers’ entrepreneurial process.

PapersTerm Structure Analysis of Option Implied Volatility in the Brazilian Market

Applied Mathematical Sciences, v. 11, n. 14, pp. 651-664. Abstract: This paper aims at predicting the volatility term structure of a given asset. The model is based on the GARCH modeling of the asset’s volatility, from which the term structure is derived. We test if the model is able to accommodate the term structure response to volatility shocks. Using data from two important Brazilian companies, the model indeed improved standard predictions for the volatility term structure by relating the size of the volatility shock to the maturity of the option used to estimate the asset’s volatility.

ArtigosMeasuring efficiency drivers and productive slacks in UK auditing firms

Benchmarking: An International Journal, v. 24, n. 3, pp. 806-823. Abstract Purpose: The purpose of this paper is to measure the efficiency and the productive slacks of a sample of major UK auditing firms between 2005 and 2012. Design/methodology/approach: Using the bootstrapping technique as the cornerstone method, DEA estimates were computed, allowing the test for differences in the levels of efficiency and in the potentials for decreasing inputs and increasing outputs. Then, neural networks were combined with DEA estimates to model, with effective predictive ability, the drivers of auditing firms’ performance. Findings: The findings indicate an ambiguous impact of regulatory policies on efficiency levels. Results also indicate an eventual capacity shortfall, since the most important productive resource does not seem to cope with demand growth in the future. Originality/value: This paper aims to focus on efficiency, complementing previous research in the UK that focuses on productivity, and helps in establishing a decision-support system to slack evaluation.

ArtigosCargo allocation in Brazilian ports: An analysis through fuzzy logic and social networks

Journal of Transport Geography, v. 60, pp. 33-46. Abstract: Empirical and anecdotal evidence suggests Brazilian ports are running short in operational capacity for cargo handling and shipping movements. This paper focuses on the joint use of Fuzzy Logic (FL) reasoning and Social Network Analysis (SNA) to assess the cargo allocation pattern in Brazilian ports while shedding some light on policy-making directions and future research venues. Results suggest that cargo allocation patterns vary depending on the cargo type and product type. One can also infer that shippers prioritize distance in relation to other port allocation criteria. In the case of containerized cargo, this may be due to its higher value added compared to bulk cargo. Sensitivity analyses are also performed on the weights of port allocation criteria to explore opportunities for cargo relocation among ports in Brazil.

ArtigosTechnology gaps and capacity issues in African insurance companies: Selected country evidence

Journal of International Development, v. 29, n. 1, pp. 117-133. Abstract: This paper describes a variety of approaches used to assess the efficiency of a sample of major insurance companies in Angola and Mozambique between 2003 and 2012. Several data envelopment analysis estimates were generated using bootstrap technique, as this allowed the use of confidence intervals and the correction of a biased perception noted in the core estimates, in order to test the significant differences identified in efficiency levels and the input‐decreasing/output‐increasing potentials in the meta‐frontier analysis in both countries. Findings indicate that there seems to be a scarcity of opportunities to accommodate future demands, pinpointing that the technological gap ratio of the meta‐frontier is negligible.

ArtigosEfficiency thresholds and cost structure in Senegal airports

Journal of Air Transport Management, v. 58, pp. 100-112. Abstract: This paper assesses airport efficiency levels in Senegal under a stochastic environment where the satisficing concept for different performance thresholds is applied. A two-stage satisficing DEA-Support Vector Machine approach is used here to compute the impacts of cost structure on these thresholds. In the first stage, within the ambit of the satisficing DEA model, the probabilities of achieving a minimal performance threshold are computed in a stochastic fashion. In the second stage, Support Vector Machine regression is used to discriminate between high/low efficiency groups within a given performance threshold. This methodology was sufficiently robust to handle small samples. The results reveal that the cost of capital and the cost of labor are the cost structure variables that have the greatest impact on efficiency levels, besides cargo operations.

ArtigosCorporate sustainability practices in accredited Brazilian hospitals: a degree-of-maturity assessment of the environmental dimension

Revista de Administração, v. 52, pp. 26-35. Abstract: The main objective of this paper is to assess the degree of maturity of Brazilian accredited hospitals in relation to sustainable practices, specifically the environmental dimension. Therefore, a questionnaire was constructed, shaped by the literature review and the evaluation method of the Corporate Sustainability Index of BM and FBovespa (n.d.). Furthermore, the relationship between three corporate sustainability tools (the certification of the International Organization for Standardization [ISO] 14001, published sustainability reports, and the existence of an area dedicated to corporate sustainability) and the maturity of hospitals in relation to sustainability practices were assessed. The results show that, of the 38 hospitals that participated in the survey (43% of subjects studied), 58% obtained a maturity rating of very high or high rating, according to the established criteria. In addition, some research variables showed statistically significant differences among the hospitals that have ISO 14001 certification, those that publish sustainability reports, and those that have an area dedicated to sustainability. Consequently, hospitals should take action to include much more sustainability actions in their strategies, such as how to establish a participatory dialog with stakeholders, in order to improve and raise the level of maturity of hospitals.

ArtigosDemand forecasting in the beauty industry using fuzzy inference systems

Journal of Modelling in Management, v. 15, n. 4, pp. 1389-1417. Abstract Purpose: This study aims to analyze the performance of four different fuzzy inference system-based forecasting tools using a real case company. Design/methodology/approach: The forecasting tools were tested using 27 products of the nail polish line of a multinational beauty company and the performance of said tools was compared to those of the company’s previous forecasting methods that were basically qualitative (informal and intuition-based). Findings: The performance of the methods analyzed was compared by using mean absolute percentage error. It was possible to determine the characteristics and conditions that make each model the best for each situation. The main takeaways were that low kurtosis, negatively skewed demand time-series and longer horizon forecasts that favor the fuzzy inference system-based models. Besides, the results suggest that the fuzzy forecasting tools should be preferred for longer horizon forecasts over informal qualitative methods. Originality/value: Notwithstanding the proposed hybrid modeling approach based on fuzzy inference systems, our research offers a relevant contribution to theory and practice by shedding light on the segmentation and selection of forecasting models, both in terms of time-series characteristics and forecasting horizon. The proposed fuzzy inference systems showed to be particularly useful not only when time-series distributions present no clear central tendency (that is, they are platykurtic or dispersed around a large plateau around the median, which is the characteristic of negative kurtosis), but also when mode values are greater than median values, which in turn are greater than mean values. This large tail to the left (negative skewness) is typical of successful products whose sales are ramping up in early stages of their life cycle. For these, fuzzy inference systems may help managers screen out forecast bias and, therefore, lower forecast errors. This behavior also occurs when managers deal with forecasts of longer horizons. The results suggest that further research on fuzzy inference systems hybrid approaches for forecasting should emphasize short-term forecasting by trying to better capture the “tribal” managerial knowledge instead of focusing on less dispersed and slower moving products, where the purely qualitative forecasting methods used by managers tend to perform better in terms of their accuracy.

ArtigosSustainable insurance assessment: Towards an integrative model

The Geneva Papers on Risk and Insurance – Issues and Practice, v. 43, pp. 275–299. Abstract: This paper investigates the corporate social responsibility of insurance companies. The assessment procedures available today do not use environmental, social and governance (ESG) risk variables. We propose an integrative model to understand how progress in ESG risk underwriting can influence the management of ESG issues in insurance operations. This model was developed and tested by conducting a survey of 98 insurance professionals in Brazil. The model indicates only environmental and governance constructs as measurement discriminants. We have found a positive relationship between company size and progress in ESG risk underwriting and ESG issues in insurance operation management constructs. Additional analysis of the gap between ESG risk materiality and product offer provides a road map for harnessing local opportunities.

[pt] ArtigosO papel dos programas de pós-graduação em administração de empresas na perspectiva da relevância estratégica: o atendimento das expectativas dos stakeholders

Revista de Administração de Empresas, volume 58, n. 1, pp. 91-95.
Há tempos tem-se ensinado aos nossos alunos, já na graduação, que a continuidade de uma organização depende da relevância percebida por seus stakeholders (Freeman & Reed, 1983). Contudo a frase proferida por uma das mais relevantes autoras na área de Administração no Brasil, há cerca de 20 anos – quando, ainda recém-chegado na vida acadêmica, manifestei minha frustração com as imperfeições que identificava na gestão da Escola –, nunca deixou de ecoar na minha mente: “Somos famosos por ensinar Administração, não por administrar”. Infelizmente entendi que aquela frase não era uma crítica, mas uma constatação. A visão apresentada neste texto parte da motivação decorrente daquela frase. Necessário ressaltar que, naturalmente, trata-se de uma visão parcial e, também, devido à necessidade de concisão, superficial em relação àquilo que é merecedor de uma discussão mais profunda nos fóruns que afetam a gestão dos Programas de Pós-Graduação em Administração brasileiros. Inicialmente serão realizadas a nominação dos mais relevantes stakeholders e a identificação, sujeita a posterior confirmação ou não, de seus interesses mais prementes. Em seguida, utilizando-se o Relatório de Avaliação 2013-2016 – Quadrienal 2017, da Área de Administração, Ciências Contábeis e Turismo (CAPES, 2017), e focando apenas nos programas acadêmicos, é feita uma análise dos resultados obtidos nos principais quesitos de avaliação, que, no entendimento do autor, relacionam-se de forma mais direta aos interesses dos stakeholders identificados.

ArtigosGraduate business administration programs: Meeting stakeholder expectations

Revista de Administração de Empresas, volume 58, issue 1, pp. 91-95. Introduction: Traditionally, it has been taught to business administration students at the undergraduate level that the survival of an organization depends on its relevance as perceived by stakeholders (Freeman & Reed, 1983). However, one of the most important authors in the area of ​​business administration in Brazil stated that about 20 years ago-when I was a newcomer to the academy-I expressed my frustration with the imperfections I identified in the management of the school. The following line never ceased to echo in my mind: “We are famous for teaching business administration, not for managing.” Unfortunately, I found that this phrase was not a criticism, but a fact.

The motivation for this text comes from the idea expressed by the phrase above. However, it is necessary to emphasize that this is a partial vision and that forums in which Brazilian graduate programs in business administration participate tend to focus on concise discussions instead of deepening discussions on topics that affect the management of these programs.

First, the most relevant stakeholders were listed, and their pressing interests were identified (subject to confirmation). Subsequently, using the 2013-2016 Evaluation Report – Quadrennial 2017, of the business administration, accounting, and tourism areas (CAPES, 2017), and considering only academic programs, the author analyzed the results obtained for the evaluation questions in relation to the interests of the stakeholders identified.

ArtigosBorderless companies versus born globals: Why we do need another label

Emprendimiento y Negocios Internacionales, volume 3, issue 1, pp. 21-25.
Abstract
: This article is intended to show why borderless firms should be distinguished from traditional born global firms (BGs). Borderless firms have an internationally dispersed configuration of downstream, upstream and support value-added activities, an entrepreneurial team not bounded by a home base, and multinational founders, management teams and/or a multinational workforce. The concept of borderless firms emerged from analysis of empirical evidence and is intended to countervail the excessive focus of BGs literature on downstream activities. Drawing from five case studies, we found that borderless firms may be the result of ex-ante planning. However, most often, the internationally dispersed configuration of value chain activities seems to emerge from effectuation approaches, stemming from networking, including unexpected interactions, which may be envisaged as instruments to overcome constraints or to explore new business opportunities. The article shows that borderless firms present features which differentiate them from traditional BGs. Implications for entrepreneurs and researchers are provided in the concluding section.

ArtigosA digital community bank: mapping negotiation mechanisms in its consolidation as an alternative to commercial banks

International Journal of Community Currency Research, v. 22, n. 2, pp. 56-70. Abstract: This paper aims to map the negotiation mechanisms used by Banco Palmas in order to make Palmas Digital possible as a community digital bank in the Conjunto Palmeiras’ neighbourhood, state of Ceará, Brazil. Palmas Digital represents an alternative way to offer financial services in a network of community banks that was enabled by a digital payment platform called e-Dinheiro. Using a multilevel framework model proposed in Pozzebon & Diniz (2012), we seek to understand the interplay between different actors and technological artefacts in order to understand the “technology-in-practice”, concept defined by Orlikowski (2000). The multilevel framework model was built to understand social consequences of information and communication technologies (ICT) interactions at a community level.

[en] PapersThe influence of private equity in the governance of Brazilian companies

Corporate Ownership & Control, volume 15, pp. 213-221.
Abstract: The private equity (PE) investors usually seek opportunities in the target companies in order to earn high returns. One opportunity explored by PEs is the potential that the company has to improve its governance and provide a better structure for the investor, which results in the generation of shareholder value and improve market value. For this, PE enhances the adoption of good corporate governance practices with the goal of creating value for their investment. This study explores how PE improves the governance of target companies in Brazil. The quality of corporate governance is measured by a firm-level corporate governance index, by cross-listing shares in the U.S., and by listing on New Market, a special governance segment in Brazil. We estimate different panel regression and probit models to analyse the relation between PE and governance. We also test different governance metric as dependent variables and use various firm characteristics as control variables. Our results show a positive influence of PE in improving corporate governance in Brazil.

Corporate Ownership & Control, volume 16, issue 1, pp. 7-12.
Abstract: There are many studies on corporate governance and performance of companies. However, the research on governance and performance of football clubs is scarce. This paper creates a football club governance index that allows us to analyze a larger number of clubs during a longer period of time when compared to previous studies. The authors study 20 Brazilian football clubs from 2005 to 2010 and find that clubs with good governance are more profitable, generate higher revenues, and win more championships domestically and abroad.

ArtigosBacktesting Basel III: evaluating the market risk of past crises through the current regulation

Applied Economics, v. 50, n. 59, pp. 6382-6396. Abstract: Are the recommendations from the Bank for International Settlements (BIS) effective to a broad set of financial crises? We submitted two of the main Basel III recommendations for market risk to a back test: the capital requirements and the Value at Risk (VaR) methodology that includes the BIS’s Stressed VaR. We tested the main Brazilian currency exchange (U.S. Dollar to Brazilian Reais) and currency exchange swaps contracts through volatility-based VaR methodologies in the period that comprises the so-called Brazilian confidence crisis, which occurred in the second half of 2002. While the Stressed VaR revealed inapplicable, due to historical data shortage, the capital requirements level appeared innocuous, due to the high levels of daily volatility – daily oscillation limits may have a significant role on crisis mitigation. To circumvent the lack of either historical information or optimal window for stress patterns, we suggest to calibrate the Stressed VaR or the recently announced Expected Shortfall with a historical VIX (Volatility Index, Chicago Board Options Exchange), working as a volatility scale. We suggest modelling with other densities, apart from the BIS recommended standard normal.

Abstract: This article’s objective is the identification of research opportunities in the current big data privacy domain, evaluating literature effects on secure informational assets. Until now, no study has analyzed such relation. Its results can foster science, technologies and businesses. To achieve these objectives, a big data privacy Systematic Literature Review (SLR) is performed on the main scientific peer reviewed journals in Scopus database. Bibliometrics and text mining analysis complement the SLR. This study provides support to big data privacy researchers on: most and least researched themes, research novelty, most cited works and authors, themes evolution through time and many others. In addition, TOPSIS and VIKOR ranks were developed to evaluate literature effects versus informational assets indicators. Secure Internet Servers (SIS) was chosen as decision criteria. Results show that big data privacy literature is strongly focused on computational aspects. However, individuals, societies, organizations and governments face a technological change that has just started to be investigated, with growing concerns on law and regulation aspects. TOPSIS and VIKOR Ranks differed in several positions and the only consistent country between literature and SIS adoption is the United States. Countries in the lowest ranking positions represent future research opportunities.

[en] PapersForecasting USD-BRL Currency Rate Volatility using Realized and Implied Volatilities Data

Estudos Econômicos, volume 48, issue 4.
Abstract: This article assesses the impact of exogenous variables in GARCH models, when applied to volatility forecasts for the Brazilian USD-BRL currency market. As exogenous variables, we used the realized variance, based on high frequency data, and the FXVol index, based on market implied volatility data. This is the first study to use the FXVol index and to investigate its effects on Brazilian foreign exchange volatility. The results indicate statistical significance of the superiority of the extended models when predicting volatility. We conclude that high frequency data and market implied volatility contain relevant information with respect to USD-BRL currency volatility. These find ings are relevant for hedgers, speculators and practitioners in general.

ArtigosEfficiency in South African agriculture: a two-stage fuzzy approach

Benchmarking: An International Journal, v. 25, n. 8, pp. 2723-2759. Abstract Purpose: The purpose of this paper is to assess the efficiency of agricultural production in South Africa from 1970 to 2014, using an integrated two-stage fuzzy approach. Design/methodology/approach: Fuzzy technique for order preference by similarity to ideal solution is used to assess the relative efficiency of agriculture in South Africa over the course of the years in the first stage. In the second stage, fuzzy regressions based on different rule-based systems are used to predict the impact of socio-economic and demographic variables on agricultural efficiency. They are compared with the bootstrapped truncated regressions with conditional α levels proposed in Wanke et al. (2016a). Findings: The results show that the fuzzy efficiency estimates ranged from 0.40 to 0.68 implying inefficiency in South African agriculture. The results further reveal that research and development, land quality, health expenditure–population growth ratio have a significant, positive impact on efficiency levels, besides the GINI index. In terms of accuracy, fuzzy regressions outperformed the bootstrapped truncated regressions with conditional α levels proposed in Wanke et al. (2015). Practical implications: Policies to increase social expenditure especially in terms of health and hence productivity should be prioritized. Also policies aimed at conserving the environment and hence the quality of land is needed. Originality/value: The paper is original and has not been previously published elsewhere.

ArtigosA performance analysis of Brazilian Public Health: TOPSIS and Neural Networks application

International Journal of Productivity and Performance Management, v. 67, n. 9, pp. 1526-1549. Abstract Purpose: The purpose of this paper is to estimate the performance of Brazilian hospitals’ services and to examine contextual variables in the socioeconomic, demographic and institutional domains as predictors of the performance levels attained. Design/methodology/approach: The paper applied a two-stage approach of the technique for order preference by similarity to the ideal solution (TOPSIS) in public hospitals in 92 Rio de Janeiro municipalities, covering the 2008–2013 period. First, TOPSIS is used to estimate the relative performance of hospitals in each municipality. Next, TOPSIS results are combined with neural networks in an effort to originate a performance model with predictive ability. Data refer to hospitals’ outpatient and inpatient services, based on frequent indicators adopted by the healthcare literature Findings: Despite a slight performance increase over the period, substantial room for improvement is observed. The most important performance predictors were related to the demographic and socioeconomic status (area in square feet and GDP per capita) and to the juridical nature and type of ownership of the healthcare facilities (number of federal and private hospitals). Practical implications: The results provide managerial insights regarding the performance of public hospitals and opportunities for better resource allocation in the healthcare sector. The paper also considers the impact of external socioeconomic, demographic and institutional factors on hospitals’ performance, indicating the importance of integrative public health policies. Originality/value: This study displays an innovative context for applying the two-stage TOPSIS technique, with similar efforts not having been identified in the healthcare literature.

ArtigosEfficiency of Brazilian public services of kidney transplantation: Benchmarking Brazilian states via data envelopment analysis

The International Journal of Health Planing and Management, v. 33, n. 4, pp. e1067-e1087. Abstract: The Brazilian Public Health System, facing a national economic and political crisis, operates with tight budgets and poor physical infrastructure. Among the services it delivers, organ transplantation represents a complex process wherein inefficient resource allocation is a relevant issue. This study examines the technical and scale efficiency of the Brazilian public services in kidney transplantation, assessing the conversion of physical and labor inputs into kidney transplants using data envelopment analysis. This longitudinal analysis used a secondary database from the Brazilian Registry of Transplants having, as a unit of analysis, 23 Brazilian states that performed kidney transplants from 2013 to 2015. The Malmquist index is applied to examine productivity changes. Data were adjusted per million of population, and factors were extracted by principal component analysis. The results indicate that most states operate in a technically inefficient manner, resulting in a low mean efficiency score. Overall efficiency worsened during the analyzed period, and there was a significant disparity in performance between states, with higher scores in the South and Southeast—the most developed and wealthiest regions—than in the North and Northeast. The results provide managerial insights into the delivery of organ transplantation by the Brazilian public services on both the national and state levels, helping to identify opportunities for better resource allocation in this activity. Given the scarcity of studies that systematically assess and benchmark organ donation and transplantation, this work represents an innovative context of application and may be useful for the community of relevant policymakers, academics, and health professionals.

ArtigosTeam Nogueira: Invasion of Mixed Martial Arts in the Fitness Universe

Revista de Administração Contemporânea, v. 22, n. 5, pp. 786-803. Abstract: This case study describes the challenges faced by Sergio Lyra, CEO of Team Nogueira, a network of gymnasiums founded by the brothers Rodrigo and Rogério Nogueira, two of the greatest fighters in the history of Mixed Martial Arts (MMA), who had transformed their training center into a gym, and later into a franchise network. In 2015, Team Nogueira had more than thirty academies throughout Brazil. However, the slowdown in the popularization of the sport, coupled with the economic crisis that plagued the country and the retirement of the brothers that gave its name to the network created a scenario of uncertainties and concerns. This case serves as a background for the discussion on the application of marketing in the sporting context, allowing discussion about the challenges related to the alignment between segmentation, target market selection and positioning. Therefore, the case is recommended for Fundamentals of Marketing or Sports Marketing classes in undergraduate and postgraduate courses, in sessions dedicated to the discussion of segmentation, competitive positioning or marketing strategy.

ArtigosOn building partnership networks in an innovation context

Management Research, v. 16, n. 2, pp. 179-196. Abstract: Purpose: The purpose of this paper is to seek to fill the gaps found in the literature to understand why and how the partnerships are formed and to map the dynamics of partnership networks of Brazilian electricity companies. Design/methodology/approach: To map the dynamics of partnership networks formed by the Brazilian electricity companies, a social network analysis technique was adopted: R statistical software was used to make calculations and plot these networks. Findings: It was found that the partnership network had a clear potential for an increase in the number of projects; however, the partnerships for the execution of such projects were dispersed. Although the concessionaires established partnerships with diverse institutions, the latter did not intercommunicate. Moreover, when analyzing the projects with respect to the project-type investigated, the institutions engaged in specific project types can be identified; thus, there is an opportunity for concessionaires, authorized contractors and licensed companies to identify the best partners, i.e. those that already possess the expertise to execute specific projects in future partnerships. Originality/value: The purpose of this paper is to fill the gap in partnership network development dynamics to understand how such networks form, change and evolve over time.

[en] PapersSocial networks and health practices: influence of a diabetes online community on adherence to treatment

Ciência & Saúde Coletiva, volume 23, issue 10, pp. 566-580.
Abstract: This study aims to understand how online communities can contribute to increasing the adherence of chronic patients to the treatment prescribed by the physician in Brazil. For this purpose, we applied the netnography method to analyze the community Diabetes: vivendo e aprendendo – troca de informações (free translation: “Diabetes: living and learning – information exchange”), considering the dimensions of adherence proposed by the World Health Organization (WHO) as a theoretical framework. The analysis shows the influence of cyberculture on health and disease processes, resulting in changes in physician-patient relationships, patient empowerment, and individual management of own chronic condition. The results also showed a positive influence of the interactions established in the community on the multidimensional factors of the adherence model proposed by the WHO1, also leading to the possibility of including a sixth related to connectivity. The primary motivations identified for community participation were access to information on the disease and treatment, the sharing of experiences and social support. Thus, the proposition of health policies that help chronic patients meet these needs tends to contribute to increased adherence to treatment.

Resumo
: Este estudo visa compreender como as comunidades online podem contribuir, no Brasil, para aumentar a adesão de pacientes crônicos ao tratamento prescrito pelo médico. Para tanto, realizou-se a netnografia da comunidade Diabetes: vivendo e aprendendo – troca de informações, considerando como arcabouço teórico as dimensões da adesão propostas pela Organização Mundial de Saúde – OMS. A análise evidencia os impactos da Cibercultura sobre os processos de saúde e doença, provocando mudanças nas relações médico-paciente, no empoderamento do paciente e na gestão individual de sua condição crônica. Os resultados mostraram também uma influência positiva das interações estabelecidas na comunidade sobre os fatores multidimensionais do modelo de adesão proposto pela OMS, conduzindo ainda à possibilidade de inclusão de uma sexta dimensão referente à conectividade. As principais motivações identificadas para participação na comunidade foram o acesso a informações sobre a doença e o tratamento, o compartilhamento de experiências e o suporte social. Assim, a proposição de políticas de saúde que auxiliem os doentes crônicos a atenderem tais necessidades tende a contribuir para aumentar a adesão ao tratamento.

ArtigosEthanol production in Brazil: empirical evidence based on persistence

International Journal of Energy Sector Management, v. 12, n. 4, pp. 566-580. Abstract: Purpose: This paper aims to investigate the production of sugar cane ethanol in Brazil for the time period 1983-2016, separating the data by geographical location. Design/methodology/approach: For this purpose, the authors use techniques based on the concept of fractional integration. Findings: The authors show that the data corresponding to the total production is highly persistent, with an integration order smaller than 1 but close to it. In fact, the unit root hypothesis cannot be rejected implying that shocks have a permanent nature, and thus requiring policy measures to recover the level from exogenous shocks. Separating the data into two sub-regions, namely, North–Northeast and Central–South, higher levels of persistence are detected in the latter, while the former presents some evidence of mean reverting behavior, implying that shocks will disappear by themselves in the long run in the former regions. These results are obtained from all the different methods used. Originality/value: The originality is based on the time series techniques used in the paper that departs from the classical methods based on unit roots and integer degrees of differentiation.

ArtigosOrganizational change in a scenario of political upheaval and economic crisis: a Brazilian case

Management Research Review, v. 41, n. 10, pp. 1118-1136. Abstract: Purpose: This paper aims to enhance the understanding of organizational change (OC) and the main critical factors to change. Design/methodology/approach: A single case study was conducted in a large company with operations in Brazil by means of 21 in-depth interviews. A qualitative perspective was applied to scrutinize the data collected. Findings: Main critical factors, such as commitment and trust, represent pieces of a puzzle that, when put together in a constructive way, draw a path to successful implementation of a change initiative. On the one hand, a country crisis poses as an obstacle to build change initiative credibility. On the other hand, an economic downturn may represent a retention mechanism. This study allowed the authors to draw a diagram with four groups of people based on their engagement with the organization change initiatives and on their seniority. In brief, the company is in a vicious circle. It is prisoner of a negative loop that causes a destructive effect in the change process, and it does not allow them to think out of the box and explore creative alternatives to face the company challenges. Research limitations/implications: The research presents a few limitations regarding the chosen method and, also, country and company scenario where the research took place. Practical implications: The results have implications for human resources development (HRD) scholars and practitioners in the planning and implementation of OC-related initiatives. Originality/value: This paper contributes to OC literature and practitioners by showing the importance of credibility in change initiatives to achieve their successful implementation. This study also supports the strong relationship among main critical factors to change. Finally, the company is locked in a negative loop that stifles the successive attempts to successfully implement the change initiatives.

ArtigosSelective and “veiled” demarketing from the perspective of black female consumers

Organizações & Sociedade, v. 25, n. 87, pp. 610-631. Abstract: This study sheds light on the perspective of Black female consumers in regard to certain effects of marketing initiatives adopting the literature on demarketing as a framework. The context examined is their experience with the market of hair beauty and care. Media actions are analyzed along with narrative interviews in order to understand the phenomenon. The findings reveal a dominant structural pattern which perpetuates the marginalized status of Black women’s natural traits. Emerging market initiatives point to movements concerning the visibility of these female consumers, who despite being eager to consume, have their demand discouraged. This suggests that they perceive selective and veiled demarketing as one of the results of marketing actions. The analysis invites for theoretical reflections on demarketing and veiled racism in Brazil.

Resumo: Este trabalho traz a visão da consumidora negra sobre efeitos de ações de marketing, apoiando-se na literatura sobre demarketing. O contexto investigado é sua experiência no mercado de tratamento e beleza dos cabelos. Informações originadas de diferentes manifestações midiáticas se somam às entrevistas narrativas para a interpretação do fenômeno. Os achados revelam um padrão estrutural dominante, que perpetua a condição marginal dos traços naturais dessas mulheres; aspectos emergentes do mercado, que apontam movimentos rumo à visibilidade dessa consumidora, e que essas mulheres se mostram ávidas por consumir, mas se sentem desencorajadas em sua demanda. Isso sugere que percebem o demarketing seletivo e velado, como um dos efeitos das ações de marketing. A análise dá origem a reflexões teóricas sobre demarketing e racismo velado no Brasil.

ArtigosVolatility smiles when information is lagged in prices

The North American Journal of Economics and Finance, v. 46, pp. 151-165. Abstract: This study explores volatility smiles when stock market information is lagged, specifically in the REIT industry. A usual requirement is that REITs can only disseminate information relating to their property valuations once per year; therefore, this leads to the lagging effect. Within the context of exchange options (i.e. mergers), it seems that no study has researched on this theme. This article uses the Black & Scholes model to calculate implied volatilities and their corresponding implied options to illustrate arbitrage opportunities when exchange options emerge. The results illustrate that implied volatilities are different from non-implied volatilities. Further, arbitrage is still higher among REITs as opposed to other capital market instruments. Finally, just like other capital market instruments, REIT acquisitions generate alpha.

Journal of Information Systems and Technology Management – Jistem USP, v. 15. Abstract: This research analyzes how the perception of organizational injustice motivates the practice of cybercrimes in the workplace. In a qualitative and exploratory investigation, interviews have been carried out for 16 specialists in cybernetic security. Data were analyzed through the categorical content analysis technique. The results obtained suggest that the perception of injustice produces negative feelings, such as low self-esteem, frustration, and lack of guilt, and these emotions, in turn, motivate the practice of cybercrimes. Different perceptions have been identified among the interviewees of this study, which are associated with the literature review related to the theme, allowed the proposition of a conceptual model.

ArtigosAmbidextrous strategy in restaurant chains: The “Standardization VS. Innovation” Dilemma

Revista Alcance, v. 25, n. 1, pp. 20-37. Abstract: Restaurants that expand through replication face two challenges: the pursuit of exploration and exploitation. On one hand, exploration is linked to the idea of creating new processes and routines i.e. innovation. On the other hand, exploitation is the ability to refine existing processes, i.e. to standardize successful routines. An ambidextrous strategy simultaneously pursues these two capabilities. Companies have two ways to promote ambidexterity. Contextual ambidexterity assumes that the same group can perform both exploration and exploitation. Structural ambidexterity, meanwhile, involves the formal separation of organizational structures dedicated to exploration/exploitation. This study seeks to understand how restaurant chains promote ambidextrous strategies, taking as its point of departure the trade-off between innovation and standardization. A qualitative study was conducted, based on the case study method, analyzing nine restaurant chains in the city of Rio de Janeiro from the perceptions of their strategic managers. This study was able to identify two levels of structural ambidexterity in restaurant chains: natural and deliberate. Similarly, different degrees of engagement were found with the ambidextrous strategy in contextual form: the company management, the restaurant unit, and at individual level, with the employees of the unit.

ArtigosEstratégia ambidestra em redes de restaurantes: O dilema “Padronização VS Inovação”

Revista Alcance, volume 25, n. 1, 20-37.
Resumo: As empresas de alimentação que se expandem através de replicação enfrentam dois desafios: a busca por exploration (capacidade de inovar) e exploitation (padronização). De um lado exploration está ligado a ideia de criação de novos processos e rotinas. Por outro, exploitation é a capacidade de aperfeiçoar processos já existentes. Perseguir simultaneamente essas duas capacidades é possuir uma estratégia ambidestra. Existem duas formas de ambidestria: estrutural e contextual. A ambidestria contextual parte da premissa que exploration e exploitation podem ser executadas pelo mesmo grupo de trabalho. A ambidestria estrutural, por sua vez, consiste na formação de estruturas organizacionais dedicadas a exploration/exploitation. O objetivo deste artigo é entender como a redes de restaurantes perseguem estratégias ambidestras, determinando qual o tipo de ambidestria adotada em cada situação gerencial. Para atingir tal objetivo o presente estudo se desenvolveu a partir de 9 entrevistas semiestruturadas com gestores com visão estratégica de redes de restaurantes da cidade do Rio de Janeiro. Este estudo foi capaz de identificar dois níveis de ambidestria estrutural em redes de restaurantes: a natural e a deliberada. De forma análoga, foram encontrados níveis de engajamento das redes com a estratégia ambidestra na forma contextual: na cúpula da rede, na unidade dos restaurantes e no nível individual, dos funcionários das unidades. Dessa forma, este artigo contribui para o debate acadêmico e para o gerenciamento estratégico da estratégia ambidestra em cadeias empresariais tendo como ponto de partida o trade off entre inovação e padronização.

Abstract: The Uppsala model is the result of an intellectual journey where economic-type assumptions were purged and replaced by behavioral, network relationship, dynamic capabilities, effectuation, entrepreneurship and institutional theories, theories which seemed to explain better, the internationalization process in the current business environment. This conceptual paper illustrates how the Uppsala model evolved showing adaptions it went through and discuss whether the Uppsala model is contingent enough to explain the rise of EMNEs, a phenomenon that at first, puzzled international business scholars and questioned the validity of well-established stream of thoughts in the international business community.

Abstract: This article proposes a structured method to map the main elements of complex phenomena. We chose Precision Medicine as the context for this study due to its novelty, exponential evolution, complexity, and potential impact on our future. The method proposed faces the problem that a subjective process of acquiring knowledge and building a common framework might be biased. The solution is achieved by an original way of combining systematic literature review, content analysis, and ecosystem approach. The method proposed also offers an innovative way to include factors and connect them to actors in an ecosystem approach. We present a four-phase method that ends with a double-layer diagram with actors and factors. It serves as a reference ground for discussions that are relevant for academic research and practitioner strategy development. Our findings in the Precision Medicine context suggest that this method could be used for other complex phenomena as well.

ArtigosEfficiency of specialized 3PL providers in an emerging economy

International Journal of Production Economics, v. 205, 163-178. Abstract: Economic growth increases the need for continuous improvement of logistic processes. In this context, comprehensive services and high-level operational performance are competitive advantages, with special attention to refrigeration services in the cold chain. This study’s main objective is to determine the variables that significantly affect the efficiency of third-party logistics (3PL) providers of refrigeration services and propose ways to improve the competitiveness of specialized 3PLs. This study uses Data Envelopment Analysis (DEA) and robust regression approach in secondary data from the annual study published by Revista Tecnologística (years 2008–2016). The aim is to measure the impact of contextual variables on the efficiency of Brazilian 3PL providers of refrigeration services. Results indicate that, in fact, pure, technical and scale efficiency levels are differently impacted by the type of technology adopted and the services offered, what leaves room opened for the adoption of different measures and operational practices to increase efficiency levels in its different dimensions. The study provides guidance for managers who wish to establish or adapt specialized 3PL structures and management systems in cold chains. Our study is the first to help identifying the main determinants of efficiency for 3PL providers of refrigeration services in an emerging economy. Further, it develops performance benchmarks for specialized logistics services.

ArtigosA critical approach to human helping in information systems: Heteromation in the Brazilian correspondent banking system

Information and Organization, v. 28, n. 3, pp. 111-128. Introduction – Information systems often fail after implementation. Sometimes they fail because users refuse to incorporate them into work. Other times they fail because they do not provide hoped-for benefits. Strategies to avoid failure include user training (so users might better operate the system), user input into design (so designers might better craft the system for use), and user alterations (so users might better fit the system to use) (e.g., Jasperson, Carter, & Zmud, 2005; Majchrzak, Rice, Malhotra, King, & Ba, 2000; Markus & Mao, 2004). These strategies often rest on the implicit premise that a gap between how designers envisioned system use and how users experienced the system begets failure (Heeks, 2003; Suchman, 2002). Narrowing the gap between designers’ conceptions and users’ reality thus becomes the goal in many efforts to achieve system success. Information systems can nonetheless succeed if human users provide labor to bridge the gaps. Ekbia and Nardi (2014, 2017) coined the term “heteromation” (in contrast to automation, which removes humans) to describe this labor relation in which organizations or individuals appropriate the economic value generated when users provide the labor necessary to make an information system work. Because users’ labor is typically thinly compensated, if at all, heteromated systems carry with them the risk of labor exploitation (Ekbia & Nardi, 2012, 2014, 2017). As such, these systems underscore van Dijck’s (2009) concerns about an increasingly participatory culture that lauds unpaid contributions to the corporate good. Following critical scholars of digitalized labor such as Fuchs and Sevignani (2013), Andrejevic (2015), Berg and De Stefano (2017) and many others, it is imperative that we consider how heteromation can serve useful purposes while ensuring worker rights. Berg and De Stefano (2017) pointed out that computermediated labor can be managed to regulate work and protect workers, if the right protections are in place. We are a long way from such protections. We hope this paper raises awareness of the fact that heteromation is value-producing labor and as such, it should be part of conversations about worker rights.

ArtigosInvestigating the drivers of railway performance: Evidence from selected Asian countries

Habitat International, v. 80, pp. 49-69. Abstract: Although efficiency measurement has become relevant for logistics infrastructure planning, research on railway efficiency still remain scarce and rather focused on discussing rankings to the detriment of possible improvement paths. In fact, while the use of multi-activity models is increasing in railway efficiency research, previous studies fail short to assess their drivers at each operational stage. Here, we develop a novel super-efficiency Multi-activity Network DEA (MNDEA) model – based on directional distance functions (DDFs) and capable of handling undesirable outputs – to assess how different contextual variables impact railway efficiency levels in Asia. Two case studies are provided: one focused on six different countries, taken in aggregate (Japan, Thailand, Vietnam, Malaysia, Myanmar, and Indonesia). The other, on major state-owned Chinese railways. Differently from previous research, Generalized Additive Models for Location, Scale and Shape (GAMLSS) are used for the first time to regress super-efficiency scores on the contextual variable set. Findings reveal that the Asian railways are strongly marked by heterogeneity, the Chinese railways need to improve passenger-operation efficiency, while the other countries need to increase the cargo-operation efficiency. It also sheds lights on the design of policies for efficiency improvement in several different areas for the Asian railway system.

ArtigosThe phenomenon of internationalization and scale-up enterprises: a systematic literature review

Internext, v. 13, n. 2, pp. 71-85. Abstract: This work analyzed the pertinent literature, identifying possible relationships between the high growth of scale-up enterprises and their internationalization process. For this purpose, a systematic literature review was conducted in the fields of International Business to pinpoint intersections and gaps in the research for empirical exploration and investigation. The results of the analysis are intended to identify possibilities and make theoretical contributions to the field, especially with regard to small and medium-sized ventures. The bibliographic review was conducted using the Google Scholar and Scopus databases. These bases were chosen for their relevance, range and accuracy. Google Scholar isconsidered the best system for tracing websites and academic PDFs, while Scopus is recognized as the largest scientific database of citations and abstracts of peer-reviewed literature. To complement the survey, Scopus metadata analysis resources and NVivo 11 software were used to analyze the content of articles. The findings did not identify a relationship between internationalization and the phenomenon of Scale-ups in the literature in the field of International Business and high growth.

ArtigosEnergy efficiency drivers in South Africa: 1965–2014

Energy Efficiency, v. 11, n. 6, pp. 1465–1482. Abstract: This paper presents an assessment of energy performance in South Africa from 1965 to 2014 using the technique for order of preference by similarity to ideal solution (TOPSIS). In this research, TOPSIS is used first in a two-stage approach to assess how energy in South Africa has performed using the most frequent indicators adopted by the literature. Afterwards, in the second stage, neural networks are combined with TOPSIS results as part of an attempt to produce a model for energy performance with good predictive ability. The results reveal different impacts of contextual variables such as the rise of China in foreign trade, the Apartheid Regime, and oil shocks on energy performance in South Africa.

ArtigosCorporate governance and fundamental indexation in Brazil

Economics Bulletin, volume 38, n. 3, pp. 1494-1504.
Abstract:
Fundamental indexation uses fundamental indicators to weight stocks in a portfolio but evidence about its outperformance in across countries is mixed. It is possible that different legal environments impact these results. Brazilian companies voluntarily join one of four stock exchange listing segments with incrementally more demanding listing requirements about corporate governance (CG). The Brazilian market offers, thus, an opportunity to assess fundamental indexation in the same legal environment but under different listing requirements. The sample period begins in 2003 and ends in 2015. Categorical variables indicate the CG quality according to each listing segment. The fundamentals of a company used in fundamental indexation are multiplied by the corresponding categorical variable to compute portfolio weights. Companies with hypothetically better CG practices enjoy greater weights. The results show that such fundamental portfolios did not outperform, given that their estimated alphas are not significant when estimated with a five risk-factor model. Fundamental indices seem to be a variation of a value strategy and their performance was not influenced by different listing requirements in the same legal environment. It is possible that previous mixed results across countries were simply due to sample and period biases and not to the different legal environments.

ArtigosA cultura brasileira no olhar do estrangeiro: Percepções de alunos de um MBA internacional no Rio de Janeiro

Revista Alcance, volume 24, issue 4, pp. 554-573.
Abstract: The study aimed to verify whether and how the categories of the main theoretical models of cultural dimensions identified in an initial literature review were reflected in the perceptions of experiences and described by foreign MBA students during their stay in the Brazilian city of Rio de Janeiro. For this purpose, a qualitative study was carried out, based on analysis of written reports of forty students of seventeen different nationalities. Based on the analysis of the reports, we identified correlations with most of categories of cultural models, and found the existence of biases in perception and judgment among the students from different cultures. Finally, the results suggest the development of multicultural abilities during the International MBA, helping the students to relativize and better understand the differences between their own and the Brazilian culture. Thus, we were able to see the effective contribution of the study to increase academic knowledge about the perceptions of foreigners in relation to Brazil and Brazilians, albeit with some with limitations, thus fulfilling its initial proposal.

Resumo
: O estudo se propôs a verificar se e como as categorias dos principais modelos teóricos de dimensões culturais identificados em revisão bibliográfica inicial se refletiam nas percepções das experiências vividas e descritas por alunos estrangeiros durante sua estada no Brasil para a participação em disciplinas de curso de MBA internacional, realizado no Rio de Janeiro. Para tanto, foi desenvolvida pesquisa qualitativa baseada na análise de relatos escritos de quarenta alunos, provenientes de dezessete diferentes nacionalidades. A partir da análise dos relatos, identificamos correlações com a maioria das categorias dos modelos culturais e constatamos a existência de vieses de percepção e julgamento entre alunos provenientes de diferentes culturas. Por fim, os resultados da pesquisa apontam para o desenvolvimento de habilidades multiculturais durante o MBA internacional, ajudando os alunos a relativizar e a compreender melhor as diferenças entre as suas culturas e a brasileira. Desta forma, podemos verificar a efetiva contribuição do estudo para aumentar o conhecimento acadêmico sobre as percepções de estrangeiros em relação ao Brasil e aos brasileiros, ainda que com limitações, cumprindo assim a sua proposta inicial.

ArtigosAssessing the strategic fit of potential M&As in Chinese banking: A novel Bayesian stochastic frontier approach

Economic Modelling, v. 73, pp. 254-263. Abstract: Banking in China is well-known for being extremely fragmented, thus making the analysis of the sector not a straightforward task. This study aims to explore the strategic fit of potential mergers and acquisitions in the Chinese banking industry. When the operations of two banks are jointly analyzed this means that the inputs and the outputs of these two individual banks are somehow combined in an attempt to better understand the sector as a whole. A novel SFA model with Bayesian inference on input/output prices is proposed to assess the impact of business-related variables on efficiency levels. The results not only reveal that bank size, type, and origin present a significant impact on individual technical efficiency levels, but also exert a significant impact on the efficiency frontier of the industry. The strategic fit of M&As in the Chinese banking industry strongly relies on opportunities derived from banking automation that may arise from acquiring technologically obsolete small banks. Big and foreign banks also exert a positive impact on the technological catch-up of Chinese banks, which may suggest opportunities for sector deregulation.

ArtigosEfficiency in banking of developing countries with the same cultural background: A novel distance function frontier model

Journal of Economic Studies, v. 45, n. 3, pp. 638-659. Purpose: The purpose of this paper is to analyze the bank efficiency in three developing countries, namely Angola, Brazil and Mozambique, aiming to infer differences given that they belong to the same cultural tradition. The underlying idea is to control for the cultural background, thus allowing the discussion on how different socio-economic and historical variables maybe impacting different levels of banking efficiency and returns to scale results within the ambit of these three countries. Design/methodology/approach: Due to the presence of latent inefficiency, the authors have to modify the technique to accommodate simulation by importance sampling; therefore, in effect, the authors use a local maximum simulated likelihood approach. Findings:The results reveal that Brazil has the highest level of output-oriented efficiency, followed by Angola and then Mozambique. The same ranking is observed in returns to scale, except that vis-à-vis technical change, Brazil and Angola rank first. Finally, inefficiency derived from technical change is highest in Mozambique, followed by Angola and then Brazil. Therefore, these results reveal that the countries with the highest degree of development are higher in efficiency. Originality/value:Previous studies have identified factors such as legal tradition, accounting conventions, regulatory structures, property rights, culture and religion as possible explanations for cross-border variations in financial development and economic growth. This is the first time banking efficiency is assessed in light of a common cultural background by selecting a group of countries that share the same language and colonial past. Since results are controlled for the same background, it is possible to affirm that the findings are purely related to scale size and economic/political background issues of each country.

ArtigosThe coordination of export promotion networks for the creative industries

International Journal of Export Marketing, v. 2, n. 1, pp. 4–27. Abstract: This study aims at investigating the different approaches used by three countries that are successfully supporting the internationalisation of their creative industries. The study departs from several contributions in the areas of export promotion and public networks and adopts an interorganizational perspective, focusing on network coordination. The research was based on three case studies: design in the UK, filmmaking in Colombia and the creative industries in South Korea. The data analysis used case description, within-case analysis and cross-case analysis. The results showed that the three countries have adopted markedly different coordination systems to ensure cooperation among a number of public and private entities that offer export promotion services and support and that both the centralisation of export promotion activities and the coordination of a network of institutions may work satisfactorily. However, each approach serves different purposes, given each country’s cultural and economic context.

ArtigosResearch and innovation in higher education: empirical evidence from research and patenting in Brazil

Scientometrics, v. 116, n. 1, pp. 487–504. Abstract : This study presents a hierarchical differential game between universities and scholars in order to examine innovation and research in higher education. In this stylized setup, scholars maximize the impact of their research, and universities maximize their market value. Innovations play a key role among the incentives given by the university to boost scholars’ productivity, as measured by academic publications and citations, which translates into scholars’ professional success. The scholars’ academic productivity increases university reputation and market value. Using Brazilian data, seemingly unrelated regression estimations suggest that the number of published papers grows with external funding and the percentage of faculty holding doctorate degrees, while the number of citations is associated with the presence of graduate programs and higher teaching quality. Market evaluation is, however, negatively affected by innovation, suggesting a lack of focus on patenting and technology transfer in Brazil.

ArtigosEfficiency in Asian railways: a comparison between data envelopment analysis approaches

Transportation Planning and Technology, v. 41, n. 6, pp. 573-599. Abstract: Performance analysis has become a vital part of the management practices in the logistics infrastructure. Although there are numerous applications using Data Envelopment Analysis (DEA) models to estimate efficiency in ports and airports, research on railway efficiency remains scarce. Most of the efficiency studies of railways assume that inputs and outputs are known with absolute precision. Here, we compare Stochastic-DEA and Fuzzy-DEA models to assess, respectively, how the underlying randomness and fuzziness impact efficiency levels in railway operations in six different Asian countries: Japan, Thailand, Vietnam, Malaysia, Myanmar, and Indonesia. Findings reveal that conclusions with respect to the ranking of these railways may vary substantially depending upon the type of model chosen, although efficiency scores are similar to some extent when compared within the ambits of Stochastic-DEA and Fuzzy-DEA models. Additionally, modeling choices on fuzziness, rather than randomness, appear to be the most critical source for variations in efficiency rankings.

ArtigosA DDF based model for efficiency evaluation in two-stage DEA

Optimization Letters, v. 12, n. 5, pp. 1029–1044. Abstract: In some cases, decision making units have a two-stage structure, in which the first stage uses inputs to produce outputs that are subsequently used as inputs for the second stage. This paper departs from previous two-stage data envelopment analysis by proposing a new combined model, based on directional distance function, that improves the accuracy of the efficiency scores under constant returns to scale production technologies. We compare the proposed model with the existing ones in the literature by means of a numerical analysis, showing its applicability.

[pt] ArtigosIndexação fundamental no Brasil: uma estratégia competitiva?

Revista Brasileira de Gestão de Negócios, volume 20, n. 3, pp. 361-377.
Resumo
Objetivo: Este artigo analisa a indexação fundamental em relação ao IBrX 100 e a fundos de investimentos em ações selecionados no período entre junho de 2003 e maio de 2015. Essa estratégia se baseia na ponderação por indicadores fundamentalistas e não por preços de mercado.
Metodologia: Foram formados índices ponderados segundo alguns indicadores fundamentalistas das empresas incluídas no IBrX 100. O método de ponderação fundamental dos índices considera o peso de cada ação como a razão entre valor nominal de determinado fundamento para uma ação e o somatório do mesmo fundamento para todas as empresas. Este artigo também considera uma ponderação ordinal.
Resultados: Os resultados mostram que a indexação fundamental não apresenta retornos e alfas positivos e significativos depois que se ajusta um modelo de cinco fatores de risco e se consideram custos de transação. A ponderação ordinal sugere que esses resultados não são influenciados por valores extremos dos fundamentos. A evidência também sugere que os índices fundamentais podem se sair melhor em momentos de baixa do mercado brasileiro de ações.
Contribuições: De forma geral, os índices fundamentais se assemelham a value stocks e não apresentam retorno anormal. Essa evidência, portanto, é consistente com a inexistência de produtos financeiros que empreguem esse método de ponderação no Brasil.

[en] PapersFundamental Indexation in Brazil: a competitive strategy?

Revista Brasileira de Gestão de Negócios, volume 20, issue 3, pp. 361-377.
Abstract
Purpose: This article analyzes fundamental indexation in Brazil relative to the IBrX 100 and selected stock funds in the period between June 2003 and May 2015. This strategy relies on weights based on fundamental indicators and not on market prices.
Design/methodology/approach: Fundamental indices built with the IBrX 100 stocks were weighted according to fundamental indicators. The fundamental weighting method sets the weight of each stock as proportional to a previously determined fundament value. This article also considers an ordinal weighting.
Findings: The results indicate that fundamental indices do not display positive and statistically significant returns and alphas after adjusting a five risk factor model and transaction costs. The ordinal weighting suggests that fundamental indicator outliers do not drive results. The evidence also suggests that fundamental indices might perform better in bear markets.
Originality/value: In general, fundamental indices behave like value stocks and do not present abnormal returns. This is consistent with the absence of fundamental index products in the Brazilian market.

ArtigosReverse Knowledge Transfer on Emerging Market Multinationals: A Case Study of the Largest Private Bank in Latin America

Latin American Business Review, v. 19, n. 1, pp. 77-103. Abstract: Knowledge transfer between headquarters and subsidiaries and the study of emerging market multinationals (EMMNE) are two important and rapidly growing research topics in International Business (IB) studies. This research analyzes, through an in-depth single case study, the Reverse Knowledge Transfer (RKT) processes of an emerging market multinational, more specifically the largest private bank in LATAM—Banco Itaú Unibanco S.A.—to understand how emerging market parent companies benefit from their subsidiaries’ knowledge. Our findings validate important concepts in the IB and RKT literature, contribute with valuable insights to theory generation, and indicate possible avenues for future research.

ArtigosReverse Knowledge Transfer in Multinational Companies: A Systematic Literature Review

Brazilian Administration Review, v. 14, n. 1. Abstract: The mainstream literature has focused on knowledge transfers from parent companies to subsidiaries, while paying less attention to knowledge created at the subsidiary level. But there is a growing trend to knowledge co-creation, and the responsibility of knowledge creation has shifted from headquarters to the corporation as a whole and its subsidiaries. Using a thorough systematic review over a 15-year period in top-tier journals, this thematic analysis finds interesting literature gaps to be filled and proposes a theoretical framework that conceptualizes the reverse knowledge transfer as a complex process; moreover, we offer a detailed view on the phenomenon of reverse knowledge transfer, seeking to contribute to a better understanding of it and providing a basis to assist corporate managers in global strategic planning and knowledge management and scholars in future academic research in the field.

ArtigosActor-network theory: new perspectives and contributions to consumption studies

Cadernos EBAPE.BR, volume 16, issue 2, pp. 218-231.
Abstract: There is an increase in the use of the Actor-Network Theory (ANT) in various fields of social sciences and most recently in marketing and consumption research. In marketing discipline, however, this approach has been incorporated more widely in international studies. This article argues for the applicability of ANT to the field of research consumption in Brazil. ANTs main contribution relates to its unique perspective in analyzing human-things relationships, interactions and trajectories. This article, therefore, aims to explore the existent themes and contributions, the methods of application, criticisms and comparisons with other ontology approaches facing the social and actors involved. Finally, the study discusses possibilities raised by ANT for future research, showing how its resources can rejuvenate marketing research with focus on the collective and worldly learning that exceeds cognitive, economic and cultural connections, and emphasizes socio-material aspects present in the consumer realm. Using thorough investigation of actors and their direct connections, ANT reveals findings about what is unique, but also universal in studies developed by Brazilian researchers.

Cadernos EBAPE.BR, volume 16, n. 2, pp. 218-231.
Resumo
: Nota-se um crescimento do uso da Teoria do Ator-Rede (TAR) em várias subáreas da administração, como organizações, estratégia e marketing. No último campo, entretanto, o uso dessa abordagem ainda se concentra nos estudos internacionais. O presente trabalho tem por objetivo apresentar a TAR e como ela pode contribuir para o campo de pesquisa do consumo no Brasil, tendo em vista seu olhar singular para a relação entre os indivíduos e as coisas, suas interações e trajetórias. Visa, assim, a explorar o apanhado de temáticas e contribuições já alcançadas, a aplicação de métodos, bem como críticas e comparações ontológicas acerca do olhar sobre o social e atores envolvidos. Finalmente, discutem-se possibilidades para caminhos futuros abertos pela TAR, evidenciando como seus recursos podem rejuvenescer a pesquisa de marketing ao focar seu olhar nos aprendizados coletivos e mundanos, que superam conexões cognitivas, econômicas e culturais, a partir da ênfase nos aspectos da sociomaterialidade contida na cena de consumo e seu entorno. A partir da investigação exaustiva dos atores e de suas conexões diretas, a TAR descortina descobertas a respeito daquilo que é singular, mas também universal, nos estudos desenvolvidos por pesquisadores brasileiros.

ArtigosEfficiency in Nigerian ports: handling imprecise data with a two-stage fuzzy approach

Maritime Policy & Management, v. 45, n. 5, pp. 699-715. Abstract: This article is focused on assessing the efficiency of six major Nigerian ports from 2007 to 2013 by applying a two-stage fuzzy-based methodology adequate to handle imprecise data. More precisely, fuzzy data envelopment analysis models for traditional assumptions with respect to scale returns are employed to assess the productivity of Nigerian ports over the course of time. In the second stage, fuzzy regressions based on different rule-based systems are used to predict the relationship of a set of contextual variables on port efficiency. These contextual variables are related to different aspects of port service level, berth utilization, accessibility, cargo type, and operator type. The results reveal the impact of operator and cargo type on efficiency levels. Policy implications for Nigerian ports are derived.

[en] PapersAnimal-derived food industry: risks and opportunities due to farm animal welfare

Revista de Administração de Empresas, volume 58, issue 3, pp. 285-303.
Abstract: Farm animal welfare (FAW) has emerged in recent years as a potential material issue for the animal-derived food products industry. The issue is global in scope, given the large trade flows and multinational structure of many companies in the agribusiness industry, a critical sector of the Brazilian and international economy. This exploratory study is an attempt to map the agendas of companies in the industry and compare them with the agendas of the principal stakeholders for a better understanding of the risks and opportunities facing the intangible assets of companies with regard to FAW. The mapping was carried out by consulting websites and corporate sustainability reports. The overarching result of the study is to show that the industry as a whole is neglecting FAW as a material issue.

Revista de Administração de Empresas, volume 58, n. 3, pp. 285-303.
Resumo: O bem-estar dos animais de produção emergiu, nos últimos anos, como risco ou oportunidade potencial para a indústria de alimentos de origem animal. Essa questão tem alcance abrangente, devido aos grandes fluxos comerciais e à estrutura de muitas empresas multinacionais do agronegócio, setor crítico da economia brasileira e internacional. Este estudo exploratório tentou mapear as agendas de empresas do setor e compará-las com as das principais partes interessadas (stakeholders), visando a entender melhor os riscos e oportunidades que os ativos intangíveis das empresas enfrentam em relação ao bem-estar dos animais. O mapeamento foi feito por meio da consulta a websites e relatórios corporativos de sustentabilidade. O principal resultado foi mostrar que a indústria está negligenciando a questão do bem-estar animal como um problema material.

Additionally, modeling choices on fuzziness, rather than on randomness, appears to be the most critical source for variations in efficiency rankings. Managerial implications for Angolan banks are also explored.

ArtigosExploring the long-term trade-off between efficiency and value creation in horizontal M&As: Evidence from Nigeria

African Journal of Economic and Management Studies, v. 9, n. 2, pp. 130-147. Abstract: Purpose: The purpose of this paper is to investigate the voluntary horizontal M&A impact on operating performance in Nigeria between 1995 and 2012 under different complementary approaches. Design/methodology/approach: Residual income valuation (RIV), economic value-added (EVA), data envelopment analysis (DEA) and stochastic frontier analysis (SFA). Findings: Results showed a statistically significant improvement in the technical efficiency of both bidder and target companies, the reduced efficiency levels of the bidder firms under DEA scores reveals the specifics of the productive technology. This may suggest that resulting merged companies in Nigeria may have not even become too big in scale or even reached the most productive scale size, despite their almost monopolistic position in the sector. This happens because the scale size of the sector is small per se, implying that the investments necessary to achieve synergistic gains have to be partially covered by price increases. Practical implications: This study will guide both the M&A practitioners, investment banks, and the policy makes. In terms of having to review M&A policy as well as seeing to the improvement in the infrastructural needs. Social implications: With improved performance, employment can be created thereby giving employment to the youths. This will reduce social problems. Originality/value: From the literature and records, no long-term operating performance on voluntary mergers and acquisitions has not been carried out in Nigeria. The paper seeks to know the fundamental value of the firms after these transactions with the current methodology that is acceptable from the literature.

ArtigosCorporate governance and firm performance in Latin America: a meta-analysis

Academia Revista Latinoamericana de Administración, v. 31, n. 1, pp. 195-211. Abstract: Purpose: The relationship between the role played by corporate governance (CG) mechanisms and shareholder wealth is an important and mature topic in some countries and regions. However, despite the considerable number of studies, the results are still inconclusive. The purpose of this paper is to contribute to the debate around the theme in Latin America through a meta-analysis. Design/methodology/approach: The study used meta-analytic procedures to review 42 articles produced by researchers from Latin American countries, whose samples were composed of Latin American firms. Findings: The results suggest that CG best practices are associated with better Latin American firm performance. The evidence also suggests that results are moderated by the characteristics of boards of directors, the ownership, and control structure and various simultaneous CG mechanisms, through broad indices and special CG trading segments. Originality/Value: The relationship between GC and firm performance possesses certain peculiarities in the case of Latin American countries and the literature on the region is certainly not as abundant and mature. As most of the articles reviewed were written in Portuguese and Spanish and published in local journals, the consolidation produced should also be useful for researchers throughout the world by enabling them to access their ideas.

ArtigosA two-stage fuzzy approach on the socio-economic drivers of global energy efficiency

International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, v. 26, n. 3, pp. 397-428. Abstract: Fuzzy models have been increasingly used in decision-making in the energy sector to deal with many uncertainties such as lack of data and climate change. This paper presents a global energetic efficiency analysis based on the time series data of 91 countries from 1960 to 2010, using an integrated two-stage fuzzy approach. More precisely, Fuzzy DEA models for traditional constant and varying returns to scale assumptions are employed in a first stage to assess the relative efficiency of these countries over the course of time. In the second stage, fuzzy regressions based on different rule-based systems are used to predict the impact of a set of demographic and socio-economic variables on energy efficiency. Energetic efficiency appears to be explained by the countervailing forces of urbanization, wealth inequality, and social development. Thus, a transition to a more energetic efficient lower carbon society will depend on how we address certain socio-political factors, such as pursuing a more sustainable urbanization, reducing inequalities and taking into consideration socio-environmental aspects in trade agreements.

ArtigosInformation systems and intergovernmental relations in Brazilian social policies: a study on users? adaptations to the local context

RAUSP Management Journal, volume 53, n. 1, pp. 86-97.
Resumo: O objetivo neste artigo foi identificar barreiras na adoção de sistemas de informação em políticas sociais do governo federal para coordenar e monitorar a implementação dessas políticas no nível local. A análise foi construída a partir de um estudo sobre os usuários desses sistemas de informação que envolvem diferentes níveis federativos, especialmente no âmbito municipal. O governo federal brasileiro vem utilizando as tecnologias de informação e comunicação (TIC) para melhorar a coordenação federativa de diversos programas sociais. Isso significa dizer que a tecnologia é mais um componente na implementação dessas políticas, que são desenhadas para serem compartilhadas com os entes subnacionais, e se tornam, consequentemente, um dos aspectos que merecem ser estudados. Neste trabalho adota-se como pressuposto que os usuários de sistemas de informação podem mudar o contexto do uso da tecnologia e não apenas a tecnologia ou o sistema de informação em si. Essas mudanças de uso que não estavam previstas na formulação do programa podem explicar fatores de sucesso ou fracasso da adoção desses sistemas em políticas sociais coordenadas pela instância federal. Assim, foram realizados estudos de caso de dois programas sociais de diferentes áreas (educação e assistência social) em dois estados brasileiros (Pará e São Paulo). Portanto, o foco da pesquisa foi orientado para identificar como os usuários de sistemas da informação dos programas escolhidos alteram o contexto de uso desses sistemas. As conclusões do estudo identificaram duas dimensões que podem trazer dificuldades ou mudanças quanto ao uso de sistemas de informação intergovernamentais no âmbito local: capacidades técnicas e administrativas dos municípios brasileiros; e, rigidez dos sistemas de informação e compartilhamento dos dados e informações com os entes subnacionais participantes das políticas sociais

ArtigosApplication of local projections in the monetary policy in Brazil

Applied Economics Letters, v. 25, n. 13, pp. 941-944. Abstract: This article examines the relationship between selected monetary aggregates and inflation and output in Brazil. Impulse responses under VAR and local projections were used to discover the leading or lagging role of the monetary aggregates. In addition, the information provided by the monetary aggregates as predictors of output and inflation was examined. This was assessed by examining their predictive power for subsequent observations on an in-sample basis. Overall, the results indicate that in order to control inflation rates, Brazilian authorities should focus on restricting money supply rather than increasing interest rates.

ArtigosEfficiency Driver in Nigerian Airports: A Bootstrap DEA–Censored Quantile Regression Approach

Journal of Aviation Technology and Engineering, volume 7, issue 8, pp. 15-31. Abstract: This paper reports on the use of a novel two-stage approach for assessing the efficiency of 30 major Nigerian airports from 2003 to 2013 based on bootstrapped data envelopment analysis (DEA) and censored quantile regression. In the first stage, bootstrapped efficiency estimates are computed. They enable bias correction and testing for significant differences in efficiency levels among airports. Subsequently, bootstrapped DEA results are combined with censored quantile regression to assess the impact of contextual variables—related to the airports’ ownership, location, and network connectivity—on different efficiency percentiles. The results reveal that the intensity of significant impacts regarding airports’ contextual variables may vary between high-/low-efficiency airports. Policy implications are derived accordingly.

ArtigosMalmquist productivity indexes in Chinese ports: a fuzzy GMSS DEA approach

International Journal of Shipping and Transport Logistics, v. 10, n. 2, pp. 202–236. Abstract: This research focuses on the productivity assessment of 17 major Chinese ports from 2006–2015. Differently from previous works, a network productive structure formed by two stages was considered. In the first stage, fixed and other assets, altogether with human resources, are used to generate operating costs used as intermediate inputs, while the depreciation/amortisation of such assets is considered as an exogenous output. In the second stage, each port uses these costs generated in the first stage to produce operating profit, while cargo demand is considered as an exogenous input that enters the system. Then, bootstrapped regression trees are used to predict the relationship of a set of contextual variables related to the technology, financial health and location. Results indicate that the former two determine the productivity change of Chinese ports. When the expansion of scale has not jeopardised the financial health, the productivity will increase. Implications are also derived.

ArtigosPrivate pension funds: passivity at active fund prices

Revista Contabilidade & Finanças, volume 29, issue 76, pp. 148-163.
Abstract: From 2005 to 2015, the total assets managed by open private pension funds increased more than six times in Brazil, where the Free Benefit Generating Plan (PGBL) and the Free Benefit Generating Life (VGBL) represent 90% of these assets. However, private pension institutions are characterized by the collection of high management fees, thus keeping for themselves much of the benefits offered by the government as incentive for investment in this modality. High management fees are justified only when there is active management of these funds, theoretically generating higher performance: this study indicates that this is not the case in this market segment. Similar problems have been faced in other countries, such as the United Kingdom, Denmark, and Sweden, which filed investigation concerning funds that charge high management fees for active management, while they actually provide management that may be regarded as passive. This demonstrates the scale and relevance of this issue, which has been surveyed and addressed by this study. To do this, dynamic style analysis was performed, through rolling regressions, followed by Kalman filter analysis in funds from the top-five private pension institutions in Brazil. Analyzing the exposure evolution of these funds to various asset classes and the R2 generated, passivity traces were found, mainly in composite variable income funds. Such funds are precisely those that should be more actively managed, as they charge the highest management fees. This article also demonstrates it is possible to build a passive portfolio, having a very similar style and returns without statistically significant differences, but at a lower management fee (and aligned with passive funds).

ArtigosManaging slow-moving item: a zero-inflated truncated normal approach for modeling demand

PeerJ Computer Science, pp. 1-22. Abstract: This paper proposes a slow-moving management method for a system using of intermittent demand per unit time and lead time demand of items in service enterprise inventory models. Our method uses zero-inflated truncated normal statistical distribution, which makes it possible to model intermittent demand per unit time using mixed statistical distribution. We conducted numerical experiments based on an algorithm used to forecast intermittent demand over fixed lead time to show that our proposed distributions improved the performance of the continuous review inventory model with shortages. We evaluated multi-criteria elements (total cost, fill-rate, shortage of quantity per cycle, and the adequacy of the statistical distribution of the lead time demand) for decision analysis using the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). We confirmed that our method improved the performance of the inventory model in comparison to other commonly used approaches such as simple exponential smoothing and Croston’s method. We found an interesting association between the intermittency of demand per unit of time, the square root of this same parameter and reorder point decisions, that could be explained using classical multiple linear regression model. We confirmed that the parameter of variability of the zero-inflated truncated normal statistical distribution used to model intermittent demand was positively related to the decision of reorder points. Our study examined a decision analysis using illustrative example. Our suggested approach is original, valuable, and, in the case of slow-moving item management for service companies, allows for the verification of decision-making using multiple criteria.

ArtigosEvaluation of ethanol multimodal transport logistics: a case in Brazil

International Journal of Operational Research, v. 38, n. 3, pp. 364-391. Abstract: This paper evaluates a large ethanol multimodal logistics system in Brazil. This system conducts ethanol logistics activities using pipelines and waterways to supply Brazil’s internal and export markets. A transhipment model is used for the treatment of logistic flows. A linear programming model was developed to determine the transhipment and replenishment flows from more than 400 ethanol plants to more than 70 terminals and distribution centres. We found that optimal results occur when pipeline and waterway systems reach full capacity by taking volume from road transportation on long distances, suggesting that these options have the potential to make the ethanol logistics in Brazil more efficient and competitive in the future.

ArtigosA two-stage fuzzy neural approach for credit risk assessment in a Brazilian credit card company

Applied Soft Computing, v. 92. Abstract: This study explores and evaluates the use of soft computing systems for clients’ credit risk assessment in a Brazilian private credit card provider through the development of an innovative two-stage process, both involving soft computing techniques (fuzzy and neural networks). We use commercially available credit score ratings both in the development of our method and for benchmarking. After describing the development of our method, we present a discussion about the comparison of performances of our method and a number of other credit scoring methods described in literature (for e.g. statistical and soft computing-based). One of the analyzed existing methods for instance involves the use of a soft computing algorithm only – Artificial Neural Networks (ANN) – for client classification into solvent or non-solvent, having a market available credit score rating as input. One of the most relevant contributions of this study however is the development of what we consider an innovative approach for credit scoring. This is a two-stage process that involves the use of a fuzzy inference model as input for an ANN model (what we call a fuzzy-neural approach), using commercially available credit score ratings as response in order to conduct the fuzzy reasoning step of the analysis. The main conclusion of our research is that, in general, our fuzzy-neural method had better results than the pure application of some market available score rating method as input to a Multi-Layer Perceptron (MLP) since it was able to reduce uncertainty by improving predictability and reducing variability of the outcomes when compared to a model with no scores. The performance of a combination of a fuzzy and a neural method was very satisfactory; the vagueness usually present in the information of a company’ database was to a certain extent, incorporated by our method with good results. From the practical perspective, although our method has not proved to be substantially better than market available options, we demonstrated that it is possible for companies to develop credit score rating mechanisms internally based on past data by using fuzzy inference systems. Under certain circumstances, companies may find this option preferable than the usual option of paying high fees to large credit scoring agencies for the use of their proprietary systems.

ArtigosBusiness environment drivers and technical efficiency in the Chinese energy industry: A robust Bayesian stochastic frontier analysis

Computers & Industrial Engineering, v. 144. Abstract: Improving the technical efficiency of the energy industry is a fundamental way to ensure energy security and sustainable development and is also a requirement of the supply-side structural reform of China’s energy. Although the business environment plays an important role in the energy industry, this relationship between efficiency and business environment has been scarcely studied. In addition, there has been no attempt made to link the financial sector and energy industry together. To this end, a novel Robust Bayesian Stochastic Frontier Analysis (RBSFA) is developed here, where DIC (Deviance Information Criteria) is minimized by the variance/covariance optimization of three classical distributional assumptions for the inefficiency term (u): Gamma, Exponential, and Half-Normal. The goal is to develop a RBSFA model to relate the technical efficiency of the energy industry in China with major business environment performance variables (financial sector variables, energy industry variables and macroeconomic variables). Results indicate that the efficiency level of the Chinese energy industry is quite high over the examined period, although there is a large variance between different companies. Our findings further show that increases in the efficiency of the Chinese energy industry can be achieved by increasing the level of inventories and fixed assets, as well as research and development expenses. Finally, we find that the efficiency level in the Chinese energy industry is affected by the business environment. In particular, we notice that financial sector development and competition are helpful to improve the efficiency of Chinese energy companies.

ArtigosActivism failure of state-owned pension funds with board seats in Brazil

Corporate Board: Role, Duties & Composition, v. 16, n. 3, pp. 52-62. Abstract: There is no clear positive and significant impact of institutional investor activism in Brazil possibly due to lack of skills, portfolio diversification motivations (Sonza & Granzotto, 2018), and conflicts of interest (Maranho, Leal, & Bortolon, 2020). This article investigates two high profile activism cases to assess these conjectures and address two very large and widely held Brazilian companies, which had good corporate governance indicators and were not state-controlled or closely regulated. The cases involve the two largest Brazilian pension funds, both sponsored by state-owned companies because their size and importance would make a positive outcome more likely. Yet, in both cases, the pensions funds failed in their attempts, even when acting jointly with other foreign and domestic institutional investors. The conclusion suggests that these investors may lack skills to assess the likelihood and consequences of events that occurred soon after their investment and that changed the fundamental nature of their investees. This study places the lack of activism success under the general discussion of the challenge of costly active versus passive portfolio management. Finally, there was no evidence of conflicts of interest and political alignment of these state-related pension funds in these two activism situations.

ArtigosEqually weighted portfolios and “momentum effect”: an interesting combination for unsophisticated investors?

BBR. Brazilian Business Review, v. 17, n. 5, 506-522. Abstract: This article proposes investment strategies targeted at unsophisticated investors and structured around persistence in returns, especially in the short and medium term (“momentum effect”). Sixty-four equally weighted portfolios were formed, through the variation of five different parameters: size, revision frequency, asset selection indicator, choice criterion, and formation period. The proposed portfolios’ performances were assessed from January 2009 to December 2018 and compared to the performance of BOVA11 (Exchange Traded Fund which aims to replicate Ibovespa, the main stock market index in Brazil). Transaction costs were considered. The results corroborate the hypothesis of the “momentum effect”. Winner portfolios also were indicated asgood alternatives as investment strategies, since they presented higher median returns and Sharpe ratios than the benchmark, as well as positive alphas. Additional tests showed that transaction costs can significantly impact the portfolios’ performances. The analysis presented in this paper shall be relevant to unsophisticated investors, introducing a competitive though easy-to-implement investment strategy.

ArtigosCarteiras igualmente ponderadas e “efeito momentum”: uma combinação interessante para investidores não sofisticados?

BBR. Brazilian Business Review, v. 17, n. 5, 506-522. Resumo: Este artigo propõe estratégias de investimento focadas em investidores sem sofisticação e estruturadas com base em persistência de retornos, especialmente em curto e médio prazos (“efeito momento”). Sessenta e quatro carteiras igualmente ponderadas foram formadas, por meio da variação de cinco diferentes parâmetros: tamanho, frequência de revisão, indicador para seleção dos ativos, critério para escolha e período de formação. Os desempenhos das carteiras propostas foram avaliados no período de janeiro de 2009 a dezembro de 2018 e comparados ao desempenho do BOVA11 (fundo de índice que tem como objetivo replicar o Ibovespa, principal índice do mercado acionário brasileiro). Os custos transacionais foram considerados. Os resultados corroboram a hipótese de efeito momento. As carteiras vencedoras se mostraram também boas alternativas em termos de estratégia de investimento, visto que apresentaram retorno mediano e Índice de Sharpe superiores aos do benchmark, além de alfas positivos. Testes adicionais apontaram que os custos transacionais podem impactar de forma significativa os desempenhos dos portfólios. A análise apresentada neste artigo é relevante para investidores não sofisticados, ao introduzir uma estratégia de investimento competitiva, porém de fácil implementação.

ArtigosThe work-life interface and the role of HR: employee experiences in Brazil

Community, Work & Family, v. 20, n. 4, pp. 439-456. Abstract: Work-life studies address an individual’s need to reconcile work and non-work aspects of life. With the increasing demands in both spheres, organizations have responded by developing policies and programs aimed at alleviating conflict and providing support for workers. However, the concepts of work-life balance and work-life conflict were constructed within a particular time and place and thus may be culture and context-specific. Despite an increasing trend in cross-cultural work-life studies, most research has focused on developed countries and a key issue remains examining whether theories, models and findings are valid in a less comparable setting. The present research contributes to this understanding by examining the work-life interface from the perspective of human resource professionals in Rio de Janeiro, Brazil. Findings suggest that there is little organizational support beyond what is mandated by the government and the prevalence of informal arrangements. In addition, there is a remarkable difference in terms of work-life provisions between Brazilian and multinational firms.

ArtigosA taxonomy of initiatives at work in the sharing economy

Australasian Marketing Journal (AMJ), v. 28, n. 3, pp. 81-86. Abstract: It is crucial to classify SE initiatives to better understand such a multifaceted phenomenon. However, previous attempts to classify SE initiatives seem not to contemplate the full SE complexity. Therefore, this study proposes a new classification using a broad taxonomic approach. It started by systematically selecting a set of initiatives. Then, an intensive search on secondary data about the initiatives selected was conducted in order to identify relevant attributes. Next, the attributes identified were successively aggregated resulting in four attribute groups. In the end, each initiative was analysed from the perspective of each attribute group, resulting in five SE categories: commodity intermediary, wealth redistributor, unique-service intermediary, skill redistributor, and decentralized commodity intermediary. Findings suggest that generalizations from studies focused on specific initiatives might be problematic, entrepreneurs should consider the characteristics of different SE categories to design appropriate platforms, and policymakers should avoid regulating all SE initiatives in a homogeneous manner.

ArtigosA Hybrid Genetic Algorithm-Ratio DEA Approach for Assessing Sustainable Efficiency in Two-Echelon Supply Chains

Sustainability, v. 12, n. 19. Abstract: Measuring sustainable efficiency is a wide research topic that has gained increased relevance over the course of the years, particularly in the field of supply chain management. In this paper, novel Data Envelopment Analysis—ratio data (DEA-R) models are used to assess sustainable efficiency in two-echelon supply chains based on endogenous factors. Genetic algorithms are employed to determine optimal productive weights for each echelon and the overall supply chain by taking into account the hidden correlation structures among them as expressed in non-linear multi-objective functions. A case study on 20 firefighting stations is presented to illustrate the approach proposed and its accuracy for decision-making, as long as the issues of pseudo inefficiency and over estimation of efficiency scores are mitigated. Results indicate that the method proposed is capable of reducing efficiency estimation biases due to endogenous sustainable factors by yielding overall scores lower than or equal to the product of the efficiencies of the individual stages.

ArtigosSão Felipe Hospital: Capacity management challenge in a hospital emergency

Revista de Administração Contemporânea, v. 25, n. 2. Abstract: In July 2017, the board of directors of Hospital São Felipe, a traditional hospital located in Minas Gerais, met to discuss the results of the satisfaction survey conducted at the hospital, where it was clear there was great customer dissatisfaction with the emergency service. In the previous year, the hospital emergency service received, on average, about 6,300 patients a month, divided in three specialties: general clinic, orthopedics, and ophthalmology. The director of emergency services had twenty days to submit a plan of action to address the problems identified in the emergency area, particularly those related to the waiting lines: wait time, lack of comfort, inattention of employees, and so on. The first action taken by the director was to collect data that would enable him to analyze wait times during the process: What time did the patient arrive at the emergency service? How long the patient waited to be attended by the receptionist? How long the patient waited for triage? and so on. With these data, he believed that he would have a better understanding of the process flow and would be able to propose solutions to the problem of waiting lines in the emergency area. The case was written with the educational goal of working with the concept of capacity management in services and with ways to deal with the demand variability, especially in high-touch and unpredictable services, as in the case of an emergency service.

Revista de Administração Contemporânea, v. 25, n. 2. Resumo: Em julho de 2017, a diretoria do Hospital São Felipe, tradicional estabelecimento privado localizado em Minas Gerais, se reuniu para discutir os resultados da pesquisa de satisfação realizada no hospital, em que ficou clara a grande insatisfação dos clientes com o atendimento da emergência. No ano anterior, a emergência do hospital atendera, em média, a cerca de 6.300 pacientes/mês, divididos nas três especialidades: clínica médica, ortopedia e oftalmologia. Ao diretor da emergência foi dado um prazo de 20 dias para apresentar um plano de ação para resolver os problemas identificados em sua área, particularmente os relacionados à espera. A primeira atitude tomada pelo diretor da emergência foi coletar dados que viabilizassem analisar os tempos de espera ao longo do processo. De posse dos dados, ele acreditava que teria uma melhor compreensão do fluxo do processo e que seria capaz de propor soluções para o problema da espera na emergência. O caso foi escrito, com dados fictícios, com o objetivo pedagógico de trabalhar em sala de aula o conceito de gestão de capacidade em serviços e meios de lidar com a variabilidade do processo e da demanda, como é o caso de uma emergência hospitalar.

ArtigosThe theory of cognitive-conditional conservatism in accounting

Mathematics, v. 8, n. 9. Abstract: Literature from multiple fields in psychology and economics have identified that impulsive individuals are more prone to riskier behavior and are less conservative. Accounting literature has studied conservatism for many years, and demonstrated that there are two roots of conservatism, one unconditional and another conditional to news available at decision-making. However, there is no bridge linking both. Using an analytical model, we show that the conservatism level of an accountant is lower for impulsive individuals because of their reduced focus on future consequences of their decisions, which is coupled with an increased focus on present consequences. Hence, we put forward a theory of “cognitive-conditional conservatism”, that is, a third root of conservatism. Additionally, we also prove the asymmetry property of this behavior.

ArtigosPortfolio management under multiple regimes: Out-of-sample performance

Revista Brasileira de Finanças, v. 18, n. 3, pp. 52-79. Abstract: We propose a dynamic allocation strategy for an investor which considers three unobservable economic regimes, which we estimate using returns on five Brazilian asset classes. The strategy is based on an approximate analytical solution of a realistic configuration of the economy. The out-of-sample performance exceeds those of every benchmark we consider in 6 out of 10 years, with a weekly average return significantly higher than any benchmark at the usual confidence levels. From 2010 to 2019, our strategy achieves an average return of 21.6% per annum against, for example, 9.8% p.a. of the CDI and 4.7% p.a. of the Ibovespa. In particular, a comparative analysis makes clear how important it is to include multiple regimes in portfolio allocation.

ArtigosGestão de carteiras sob múltiplos regimes: Estratégias que performam acima do mercado

Revista de Administração Contemporânea, v. 24, n. 4, pp. 300-316. Contexto: modelos de múltiplos regimes econômicos para alocação de ativos sob a função utilidade estocástica diferencial não constavam na literatura até o modelo de Campani, Garcia e Lewin (2020). Esta função está na fronteira do conhecimento pois, mais realisticamente que as demais, separa os principais parâmetros de risco do investidor. Tal configuração, porém, torna-se complexa a ponto de não admitir solução exata na literatura e a simulação de Monte Carlo não é ágil para solucionar o problema em tempo real. O modelo resolve esta questão com uma aproximação precisa o suficiente para a alocação e nosso artigo oferece a primeira aplicação fora do cenário estadunidense. Objetivo: avaliar estratégias de portfólio montadas a partir do modelo em tela, e comparar suas performances aos retornos dos principais benchmarks do mercado. Métodos: propomos estratégias com e sem vendas a descoberto sob quatro regimes econômicos latentes a partir dos retornos dos ativos: cash (CDI), renda fixa (IMA-G), ações domésticas (IBrX-100) e ações internacionais (S&P 500) em reais. Com estes parâmetros, estimamos as probabilidades de ocorrência dos regimes e definimos os pesos de cada ativo nas carteiras (estratégias de múltiplos regimes). Comparamos as performances destas carteiras com índices de mercado e modelos míopes (estratégias de regime único), calculando a significância estatística dos resultados através do teste de Wilcox. Resultados: com esta pesquisa, tornamo-nos pioneiros ao identificar pela primeira vez quatro regimes econômicos no Brasil para otimização de carteiras. Os resultados indicam que (i) a política de portfólio depende fortemente do estado corrente da economia; e (ii) as estratégias propostas superam o mercado em termos de retornos e índice de Sharpe. Conclusão: os modelos de múltiplos regimes mostram-se relevantes para a gestão de carteiras e estratégias baseadas nestes modelos, por sua vez, podem implicar em soluções que beneficiem gestores de investimentos.

ArtigosTravels and transformation of the existential condition: Narratives and representations in films starring by seniors

Revista Brasileira de Pesquisa em Turismo, v. 14, n. 3, pp. 14-31. Abstract: Tourism acts as a catalyst for positive changes in the elderly lives by providing possibilities for socialization, escape from routine, knowledge of new realities and cultures. This paper investigates aging representations and narratives of transformation processes in cinema screenplays focused on travel experiences. Analyzing cultural texts such as music, books, advertisements, television programs and films contributes to an understanding of standards and social norms. This kind of research is quite unexplored on the tourism studies, but it is a fact that cinema has become a universal art capable of revealing deep and intimate aspects of society through its narratives and representations. We have selected four films which links elderly, travel and transformation for content analysis: “The Bucket List (2008)”, “The Best Exotic Marigold Hotel (2011)”, “Last Vegas (2013)” and “A Walk in the Woods (2015)”. Right after, we built three categories of analysis: 1) motivation and choice of experiences; 2) consumption; 3) aging and stigma. The final discussion is based on existential philosophy to identify the transformative role of travelling on the elderly lives presented on the movies. Travelling is shown as possibilities to create existential authenticity, as it is capable of decrease negative feelings such as anxiety, depression and physical and psychic isolation.

ArtigosViagens que transformam a condição existencial: Narrativas e representações em filmes protagonizados por idosos

Revista Brasileira de Pesquisa em Turismo, v. 14, n. 3, pp. 14-31. Resumo: O turismo pode figurar como uma atividade catalisadora para mudanças positivas na vida dos idosos ao proporcionar possibilidades de socialização, fuga da rotina, conhecimento de novas realidades e culturas. O presente trabalho utiliza o cinema para investigar representações dos idosos e narrativas sobre processos de transformação em filmes com roteiros centrados em experiências de viagens. A análise de textos culturais tais como músicas, livros, propagandas, programas de televisão e filmes contribui para o entendimento de normas e padrões sociais existentes. Esse tipo de pesquisa ainda é pouco explorado no campo do turismo, mas sabe-se que o cinema se tornou uma arte universal capaz de revelar profundos e íntimos aspectos da sociedade através de suas narrativas e representações. Para análise de conteúdo foram selecionados quatro filmes que ligavam idosos, viagens e transformação: “Antes de Partir (2008)”, “O Exótico Hotel Marigold (2011)”, “Última Viagem a Vegas (2013)” e “Por Aqui e por Ali (2015)”. Posteriormente, foram construídas três categorias de análise: 1) motivação e escolha das experiências; 2) consumo; 3) envelhecimento e estigma. A discussão final está apoiada na lente da filosofia existencial para indicar nas narrativas dos filmes o papel transformador das viagens na vida dos idosos. As viagens são apresentadas como possibilidades de construir uma autenticidade existencial, pois são capazes de diluir sentimentos negativos tais como ansiedade, depressão e isolamento físico e psíquico.

Abstract Purpose: Data envelopment analysis (DEA) calculates the efficiency of a business unit if all the inputs are creating outputs within a “black box.” Under traditional DEA, the detailed process of that business unit is ignored. However, a network DEA can explain the black box structure and provide efficiency results for sub-sections within any business process. This study aims to propose a network DEA model that explains a bank’s total operation. Design/methodology/approach: Earlier studies have focused only on bank efficiency ignoring this breakdown. This study departs from them by using a slack-based two-stage network DEA under a novel banking business perspective. Findings: The results reveal that network DEA provides better benchmarking insights than the traditional DEA. As such, better benchmarking can guide both the banking industry managers and policy makers in Bangladesh. Originality/value: The major contribution of this study includes dividing a bank’s total operation efficiency into two sub-operations: “core operations – collecting deposits and giving loans” and “additional operations – fees, commissions and other services.”

ArtigosA critical study of electronic participation, transparency and open data in two Latin American countries

International Journal of Electronic Governance, v. 12, n. 2, pp.141 – 165. Abstract: This study compares two Latin American open government programs by focusing on electronic participation, transparency and open data practices in light of the theory of communicative action (TCA). The results show potential faults in the electronic participation and open data programs when substantial resources are not aligned with the governments’ speeches and political wills. In addition, the investigation illustrates the value of adopting the TCA to investigate open programs from a critical perspective as a viable way to expand such research to other countries, portray the status quo of open government and improve policy making.

ArtigosDo good fundamentals generate alpha?

Revista de Educação e Pesquisa em Contabilidade (REPeC), v. 14, n. 2, pp. 221-236. Objective: To verify abnormal risk-adjusted returns in Brazilian stock portfolios formed according to the F-Score that indicates the presence of good fundamentals. Method: The sample has an average of 146 companies per year, includes the period of adoption of the International Financial Reporting Standards (IFRS) from July 2008 to June 2018 and uses equally weighted portfolios formed at the end of June of each year with information from the previous year. Results: The high F-Score portfolio showed greater average returns, lower beta, and a positive and significant alpha that disappeared in the sub-period initiating after the full adoption of IFRS. Significant coefficients for the small capitalization risk premium and egalitarian weighting suggest that large companies do not dominate its performance. High and low F-Score portfolios cannot be characterized as value stocks. The low F-Score portfolio displayed a negative and significant coefficient for the moment factor, suggesting persistence of negative returns. Contributions: Portfolios with high F-Score may have less chance of catastrophic returns. The technique can be employed by less sophisticated investors to build defensive portfolios of companies with good fundamentals.

ArtigosBons fundamentos geram alfa?

Revista de Educação e Pesquisa em Contabilidade (REPeC), v. 14, n. 2, pp. 221-236. Resumo Objetivo: Verificar retornos ajustados a risco anormais em carteiras de ações brasileiras formadas com o F-Score que indica a presença de bons fundamentos. Método: A amostra tem 146 empresas por ano em média, inclui o período de adoção dos International Financial Reporting Standards (IFRS) entre julho de 2008 e junho de 2018 e usa carteiras igualmente ponderadas formadas ao final de junho de cada ano com as informações disponíveis no ano anterior. Resultados: A carteira com F-Score alto ostentou retorno médio maior, beta menor e alfa positivo e significativo, que desapareceu no subperíodo iniciado após a adoção plena do IFRS. Os coeficientes significativos para o prêmio de risco de empresas pequenas e a ponderação igualitária sugerem que empresas grandes não dominam seu desempenho. As carteiras de alto e baixo F-Score não podem ser caracterizadas como value stocks. A carteira com F-Score mais baixo apresentou coeficiente para o fator de momento negativo e significativo, sugerindo persistência de retornos negativos. Contribuições: Carteiras com alto F-Score podem apresentar menor possibilidade de retornos catastróficos. A técnica pode ser empregada por investidores menos sofisticados para formar carteiras defensivas de empresas com bons fundamentos.

ArtigosPerformance of retirement funds: An analysis focused on pure insurance companies

Revista Contabilidade & Finanças, v. 31, n. 84, pp. 490-523. Abstract: This paper analyzes the performance of Free Benefit Generating Plans (Plano Gerador de Benefício Livre – PGBL) and Free Benefit Generating Life (Vida Gerador de Benefícios Livres – VGBL) funds in the Brazilian market. This paper is unique when it comes to segregate funds managed by pure insurance companies (PICs) from those managed by large retail banks. We also discuss the impact of characteristics such as administration fee and fund size in the fund performance. The academic literature does not consider the differentiation between funds characteristics neither the type of institution that manages them. Furthermore, the available studies on this market are usually simple and, for example, do not use multifactor models to measure risk adjusted performances. The PGBL and VGBL funds performances are object of great interest since their market grows sustainably and quickly. Funds underperforming the market should improve their strategies and decrease administration costs to deliver better net performances. This work aims at improving the market competition, such that retirement products remain attractive to investors. We develop two multifactor models representing the risk sources for each class of funds analyzed (conservative and aggressive funds). The performance is thus measured by Jensen’s alpha, although we also analyze realized returns and volatilities. We also develop a multifactor model based on administrative fee and fund’s size to capture the PIC effect. Our results suggest that PGBL and VGBL funds managed by PICs perform better in terms of higher average returns with no extra volatility, when compared to similar funds managed by companies linked to large retain banks. We found that higher administrative fees do not payout and it might even destroy value in the case of funds that invest in stocks. Larger funds presented higher net returns with no extra volatility. Finally, the analysis confirmed, with statistical evidence, the higher net returns of funds controlled by PICs in two situations: (i) after controlling for administrative fee and size of the fund – from 0.8 to 1% more per year; and (ii) after controlling for market risk sources – from 0.64 to 1.18% more per year.

ArtigosDesempenho de fundos de previdência: Uma análise focada em seguradoras puras

Revista Contabilidade & Finanças, v. 31, n. 84, pp. 490-523. Resumo: Este artigo analisa o desempenho dos fundos de Plano Gerador de Benefícios Livres (PGBL) e Vida Gerador de Benefícios Livres (VGBL) no mercado brasileiro. Este artigo é único na medida em que discrimina entre fundos administrados por seguradoras puras (SEPs) e aqueles administrados por grandes bancos de varejo. Também discutimos o impacto de características como taxa de administração e tamanho sobre o desempenho dos fundos. A literatura acadêmica não considera a diferenciação entre as características dos fundos nem o tipo de instituição que os administra. Além disso, os estudos disponíveis nesse mercado são geralmente simples e, por exemplo, não utilizam modelos multifatoriais para medir desempenhos ajustados ao risco. Os desempenhos dos fundos PGBL e VGBL são objeto de grande interesse, pois seu mercado cresce de forma sustentável e rápida. Os fundos com desempenho abaixo do mercado devem melhorar suas estratégias e diminuir os custos administrativos para proporcionar melhores desempenhos líquidos. O presente trabalho visa a melhorar a concorrência no mercado, de modo que os produtos de previdência permaneçam atraentes para os investidores. Desenvolvemos dois modelos multifatoriais representando as fontes de risco para cada classe de fundos analisados (fundos conservadores e agressivos). O desempenho é assim medido pelo Alfa de Jensen, embora também analisemos retornos e volatilidades realizados. Também desenvolvemos um modelo multifatorial com base na taxa administrativa e no tamanho do fundo para capturar o efeito SEP. Nossos resultados sugerem que os fundos PGBL e VGBL gerenciados por SEPs apresentam melhor desempenho em termos de retornos médios mais elevados, sem volatilidade extra, quando comparados a fundos semelhantes gerenciados por empresas vinculadas a grandes bancos de varejo. Descobrimos que taxas administrativas mais elevadas não compensam e podem até destruir o valor, no caso de fundos que investem em ações. Os fundos maiores apresentaram retornos líquidos mais altos, sem volatilidade extra. Por fim, a análise confirmou, com evidências estatísticas, os maiores retornos líquidos dos fundos controlados pelas SEPs em duas situações: (i) após controlar para taxa administrativa e tamanho de fundo – de 0,8 a 1% a mais por ano; e (ii) após controlar para fontes de risco de mercado – de 0,64 a 1,18% a mais por ano.

ArtigosSiloed Perceptions in Pharmaceutical Supply Chain Risk Management: A Brazilian Perspective

Latin American Business Review, v. 21, n. 3, pp. 223-254. Abstract: This article maps risk perception across the pharmaceutical supply chain (PSC) in Brazil. Our paper employs the method orders-of-magnitude analytic hierarchy process to rank risks as perceived by industry, distributors, hospitals and pharmacies. We show that players have a siloed perception of risk and impact of those risks. While upstream players emphasize cost, downstream players value service; moreover, both prioritize operational risks over strategic risks. We call for further studies in Latin America: although interest in risk is growing, few studies address the PSC and even fewer realities outside the Northern Hemisphere.

ArtigosSiloed Perceptions in Pharmaceutical Supply Chain Risk Management: A Brazilian Perspective

Latin American Business Review, volume 21, n. 3, pp. 223-254. Resumo: O presente trabalho mapeia a percepção de risco na cadeia de abastecimento farmacêutico (PSC—sigla em inglês para pharmaceutical supply chain) no Brasil. Nosso estudo empregou a metodologia de ordem de dimensão no processo de análise hierárquica para classificar o risco percebido por: indústria, distribuidores, hospitais e farmácias. Demonstramos que os participantes têm uma visão compartimentada do risco, assim como do impacto do risco. Enquanto os players principais enfatizam o custo, os players secundários valorizam o serviço. O que todos têm em comum é dar mais ênfase aos riscos operacionais do que aos estratégicos. Destacamos a necessidade de estudos adicionais na América Latina, porque apesar de haver um interesse crescente sobre o risco, poucos estudos abordam a PSC e um número ainda menor versa sobre a realidade fora do hemisfério norte.

ArtigosDigital complementary currencies and public policies during the COVID-19 pandemic

Revista de Administração Pública, v. 54, n. 4, pp. 1146-1160. Abstract: Basic income programs have been used worldwide as a tool to mitigate the adverse effects of the COVID-19 pandemic. In Brazil, the implementation of federal emergency basic income initiatives faces a twofold challenge: money distribution logistics and eligibility criteria. This paper analyses the use of digital complementary currencies (DCC) to face these challenges. Complementary currencies have long existed in Brazil as part of community banks. The latter are institutions that operate at the local level and have better information regarding residents’ needs. We present the case of Mumbuca E-Dinheiro, a DCC adopted by the municipality of Maricá (RJ), and discuss how this initiative has enabled quick and safe cash distribution aimed at mitigating the effects of the COVID-19 pandemic in Brazil. We suggest that, at present, basic emergency income could be distributed through the E-Dinheiro platform, starting with the municipalities in which it already operates and then expanding to others. Interoperability with other actors in the payment ecosystem and connections with local governments are additional actions to scale up the use of digital complementary currencies to combat the coronavirus crisis.

ArtigosMoedas complementares digitais e políticas públicas durante a crise da COVID-19

Revista de Administração Pública, v. 54, n. 4, pp. 1146-1160. Resumo: Programas de renda básica têm sido utilizados em todo o mundo como uma ferramenta para mitigar os efeitos adversos da crise da COVID-19. No Brasil, a implementação de iniciativas federais de renda básica emergencial (RBE) enfrenta um duplo desafio: a logística de distribuição de dinheiro e os critérios de elegibilidade dos cidadãos. No entanto, iniciativas de moedas complementares existem há muitos anos no Brasil, estando associadas especialmente aos bancos comunitários, os quais operam no nível local e possuem conhecimento mais aprofundado sobre as necessidades dos moradores. Este artigo analisa o uso de moedas digitais complementares no enfrentamento de desafios de distribuição de renda. Apresentamos o caso da moeda complementar digital Mumbuca E-Dinheiro, adotada pelo município de Maricá (RJ). Discutimos como esta iniciativa permitiu a distribuição de renda de forma rápida e segura com o objetivo de mitigar os efeitos da pandemia da COVID-19 no Brasil. Sugerimos que, no momento atual, a RBE poderia ser paga através do E-dinheiro, começando pelos municípios nos quais ele já atua e depois se expandindo para os demais. A interoperabilidade com outros atores do ecossistema de pagamentos e articulações com governos locais são medidas adicionais para dar escala ao uso das moedas complementares digitais no combate à crise do coronavírus.

ArtigosEleições e sucessão de CEOs em empresas estatais brasileiras

Revista Brasileira de Gestão de Negócios, v. 22, pp.462-481. Resumo: Objetivo: Estudar os impactos das eleições e processos de sucessão nas ações das empresas estatais. Metodologia: Por meio de eventos de estudo, investigamos longitudinalmente os impactos de eventos políticos (eleições) e de processos de sucessão em ações de empresas estatais por mais de 20 anos. Também documentamos as mudanças no gerenciamento, mostrando que as estatais enfrentam maior rotatividade no gerenciamento do que seus pares privados. As cotações das ações foram obtidas na Economatica e dados empresariais e executivos foram recuperados na B3 e na CVM. Resultados: Há um impacto, mas não geral, de eleições e processos de sucessão nas empresas estatais. Mais recentemente, os impactos aumentaram. A rotatividade de CEOs é maior nas empresas estatais do que em pares privados e as mudanças na gestão são maiores com as mudanças de poder. Contribuições: Lançamos luz sobre fenômenos que acontecem com frequência no Brasil: sucessão de CEOs em empresas estatais e eventos políticos impactando empresas estatais.

ArtigosMothers, daughters, and luxury brands: a love triangle

Revista ADM.MADE, v. 24, n. 1, 96-114. Abstract: To understand the collective dimension of consumer-brand relationships, formed between luxury fashion brands and female dyads within a family, we analyzed the link between family identity and consumer-brand relationships. A qualitative approach was chosen to investigate 5 different families using in-depth interviews with mother-daughter dyads. The main results consist of the extension of the consumer-brand relationship construct, providing a triangulated perspective on the topic, and proposing an initial typology composed of three emerging forms of collective consumer-brand relationship: sorority initiation, prom queen friendship and in-law relationship. This study inaugurates a collective approach to consumer-brand relationship studies, especially in the luxury context, using an intergenerational female family bundle as the unit of analysis (mother-daughter-brand), whereas research has traditionally focused on individual relationships (consumer-brand). By understanding how brands navigate the family territory – building collective relationships with brands – marketing managers can finetune branding strategy and positioning, according to the role they wish their brands to exert inside the family or other collective contexts, thus resulting in higher loyalty levels.

ArtigosMães, filhas e marcas de luxo: um triângulo amoroso

Revista ADM.MADE, v. 24, n. 1, 96-114. Resumo: Para entender a dimensão coletiva do relacionamento entre marca e consumidor, analisamos a relação entre identidade familiar e relacionamento entre marcas de luxo e díades femininas em uma mesma família. Foi adotada uma abordagem qualitativa para investigar 5 famílias, com entrevistas em profundidade com as duplas de mãe e filha. Os resultados contribuem para a extensão do construto relacionamento consumidor-marca, acrescentando uma perspectiva triangular. Propomos uma tipologia composta por três formas emergentes de relacionamento coletivo consumidor-marca: iniciação da irmandade, amizade com a rainha do baile e relações familiares aparentadas. Este estudo inaugura uma abordagem coletiva dos estudos de relacionamento marca-consumidor, posto que a literatura tradicionalmente se concentrou na relação entre um indivíduo e uma marca. Ao entender como marcas navegam no território familiar, os gerentes de marketing podem ajustar a estratégia e o posicionamento da marca, de acordo com o papel que desejam que suas marcas exerçam dentro da família ou em outros contextos coletivos, resultando em níveis mais altos de lealdade.

ArtigosThe relationship between energy consumption and prices. Evidence from futures and spot markets in Spain and Portugal

Energy Strategy Reviews, v. 31. Abstract: Slow economic recovery, market concentration, and scant alternative energy sources make the Iberian energy market quite idiosyncratic when compared to the rest of the EU. This paper focusses on the Iberian energy market by dealing with the analysis of the relationship between energy consumption and energy prices by using fractional integration in the Iberian market. This technique is used in order to examine the degree of persistence of the series, looking at the spot and futures markets in Spain and Portugal. The results indicate that all the series are fractionally integrated, showing long memory and mean reverting behaviour. Moreover, a close relation between energy consumption and energy prices is found in the spot market whereas it is not found in the futures market. In fact, there is a weak relationship between the futures market and energy consumption. However, regarding energy pricing, the relationship is stronger but with the spot market itself.

ArtigosProfit status of microfinance institutions and incentives for earnings management

Research in International Business and Finance, v. 54. Abstract: We theorize that for-profit microfinance institutions (MFIs) have higher incentives to use earnings management techniques when compared to their not-for-profit counterparts. Indeed, we show empirically that, when facing a distress period, for-profit MFIs are more likely to recognize impairment loan loss provisions than not-for-profit ones in about 0.8% of assets. This is consistent with the notion that those institutions are employing “big bath” accounting practices. Finally, using the 2008 crisis as an exogenous shock and country-level recessions as an exogenous measure of distress, we replicate our results.

ArtigosDynamic network DEA and SFA models for accounting and financial indicators with an analysis of super-efficiency in stochastic frontiers: An efficiency comparison in OECD banking

International Review of Economics & Finance, v. 69, pp. 456-468. Abstract: This paper presents an assessment of 124 OECD banks during 2004–2013 in light of relevant accounting and financial indicators that reflect banking production process and performance. Novel DEA and SFA Dynamic Network Super-efficiency models are developed to handle the underlying relationships among major accounting and financial indicators. Additionally, we develop a novel super-efficiency concept for SFA to compare DEA and SFA on common grounds to the extent possible. Firstly, a relational model encompassing major profit sheet indicators, balance sheet indicators, and net income is presented under a dynamic network structure for both models under the non-parametric and parametric specifications. Subsequently, the dynamic effect of carry-over indicators is incorporated into them, so that efficiency scores can be properly computed for these three sub-structures. Differences in scores and ranks are explored by bootstrapped regressions. It reveals that results generated from the proposed models interact differently with the socio-economic and business-related variables.
