ArtigosElements that impact building a public governance model in Brazil: the case of the Brazilian Navy

Brazilian Business Review, Vol. ahead-of-print No. ahead-of-print. Abstract: This paper investigated the essential elements for building a public governance model in Brazil, with the objective of proposing an analytical framework with contributions from different theoretical lenses. The concepts and debates emerging from the literature were analyzed along with the normative instruments that guide the principles of public governance in Brazil, and, finally, empirical research was carried out in a Brazilian public organization (Brazilian Navy). The study found that, in the Brazilian context, external control bodies have been playing the role of giving rise to an increase in governance levels within the scope of public administration, restricting at first its application to the perspective of control, and involving, to a lesser extent, the concepts of governance as instruments for achieving political administrative effectiveness. This result corroborates the need to develop more comprehensive proposals related to public value creation involving the structuring of both political and administrative bodies in Brazil.

ArtigosThe potential of eParticipation in enlarging individual capabilities: a conceptual framework

Information Technology for Development, Vol. ahead-of-print No. ahead-of-print. Abstract: The success of citizens’ electronic participation, or eParticipation, depends not only on mitigating digital divide challenges, but also on facing socio-organizational issues such as citizen data privacy, ICT literacy, as well as citizen awareness and motivation to participate. Despite the efforts of several researchers to present models and frameworks for empirical applications based on the Capability Approach (CA), we found a theoretical gap when searching for scientific work addressing the social aspects of ICT applications; more specifically, how to operationalize eParticipation for good governance through CA. Hence, aiming to investigate the potential of eParticipation initiatives to enlarge individual capabilities, we carried out an in-depth literature review. As a result, we propose a conceptual framework consisting of four propositions that can contribute toward how approach and discuss the role of eParticipation to create new synergies between technology and development, addressing the demands of people, promoting participatory governance, and fostering human development.

Keywords: eParticipation; eGovernment; citizen engagement; capability approach; eGovernance.

ArtigosGuerra e negócios o que a literatura tem a dizer sobre o assunto

Organizações & Sociedade, v. 29, n. 103, pp. 707-739. Resumo: Este artigo objetiva analisar a produção científica contemporânea sobre a temática que relaciona a guerra com os negócios por meio da revisão exploratória da literatura correspondente, em que procurou-se identificar os principais temas de pesquisa e as contribuições teórico-empíricas acerca do tópico em tese. Como resultado da análise, observou-se que a guerra enseja tanto riscos como oportunidades para os negócios, apresentando-se como um ambiente dicotômico: ora propulsor, ora repulsor de investimentos. Outro aspecto evidenciado neste trabalho se refere à dispersão da literatura associada ao tema entre diversas áreas do conhecimento, o que tem dificultado a construção de uma agenda de pesquisa que explore a natureza multifacetada do fenômeno analisado. Nesse sentido, o propósito deste artigo é contribuir para a articulação de tais evidências por meio da geração de sete proposições teóricas e de um framework analítico para apontar oportunidades de pesquisa referentes ao tema em questão.

Palavras-chave: risco político; negócios; investimentos estrangeiros; guerra; teoria institucional.

ArtigosDeceitful when insecure: The effect of self-efficacy beliefs on the use of deception in negotiations

Business Ethics, the Environment & Responsibility, Vol. ahead-of-print No. ahead-of-print. Abstract: This article investigates if and how negotiators’ self-efficacy beliefs affect their use of deception in negotiation.  Specifically, we propose that self-efficacy can be inter-preted as a threat to self-concept, which encourages individuals to temporarily bypass self- regulatory obstacles by morally disengaging their cognitive moral filters, thereby enabling them to use deception in negotiation.  We test our hypotheses in three in-dependent experimental studies involving an interactive negotiation simulation, to-talizing 460 participants.  We find that negotiators with low self-efficacy regarding their negotiation abilities are more likely to use deception than those with high self- efficacy beliefs. Furthermore, we find that moral disengagement mediates the effects of self-efficacy on deception. Our findings suggest that self-efficacy plays a key role in shaping negotiators’ ethical behaviors and we identify the psychological mechanism underlying this relationship.

Keywords: deception, moral disengagement, negotiation, self-efficacy.

ArtigosCredit behavior and Financial Stability in an Emerging Economy

Economic Systems, Vol. ahead-of-print No. ahead-of-print. Abstract: One relevant issue for the management of financial stability is the monitoring of the credit market. In this sense, Basel III proposed the credit gap as the most appropriate measure to anticipate financial stability issues. However, the adoption of the credit gap has been criticized, especially for emerging markets. Through a panel data analysis, this study investigates the effect of the credit gap and credit growth rate on financial stability in Brazil, which represents a relevant emerging economy. For this purpose, we use a set of financial stability measures traditionally found in the literature: z-score, regulatory capital and credit risk. The results suggest that the credit gap and credit growth rates are adequate metrics to indicate the sustainability of credit growth in Brazil. However, the credit growth rates are more attractive, since it indicates a threshold for credit growth in the Brazilian economy concerning financial stability.

Keywords: Credit growth, Financial stability, Emerging economies.

ArtigosEvaluating a tool for the practice of corporate social innovations: a survey of Brazilian companies

International Journal of Environment and Sustainable Development, Vol. ahead-of-print No. ahead-of-print. Abstract: To help reduce inequality, businesses are turning to corporate social innovations (CSI) to achieve both business results and social value. This study aims to evaluate and validate the CSI framework proposed by Mirvis and Googins as a tool for practicing CSI. We based our study on a survey conducted with Brazilian companies that participate in the UN Global Compact, the largest corporate sustainability initiative in the world to mobilise companies and stakeholders to do business responsibly, including 142 answers out of a sample of 609 companies. The data were analysed through a structural equation modelling (SEM) conducting confirmatory factor analysis (CFA) of the CSI framework to confirm the correlation between the five constructs, therefore establishing the validity of this framework as a tool for the practice of CSI. We expect to offer both a theoretical and a practical contribution by reinforcing the relevance of the CSI concept along with testing and validating the CSI framework as a tool to help evaluate, analyse, and implement CSI initiatives, advancing its practice and promoting the CSI concept.

Keywords: corporate social innovation; CSI; survey; LinkedIn; social innovation; structural equation modelling; SEM; confirmatory factor analysis; CFA.

ArtigosMeasuring the Grand Challenge of the Digital Transformation of Society: Practices for Operationalizing Robust Action Strategies

IEEE Transactions on Engineering Management. Vol. ahead-of-print No. ahead-of-print. Abstract: The digital transformation of society presents potential solutions to achieve goals, such as ending poverty, mitigating climate change impacts, promoting human equality, and other challenges identified in the United Nations Sustainable Development Goals. At the same time, the digital transformation is responsible for new challenges—such as fake news, Internet addiction, and cyberbullying—and for potentially promoting new sources of inequality and discrimination. For its complex, uncertain and evaluative nature, the digital transformation is one of the “grand challenges” of our time. Robust actions are lines of action that allow organizations to tackle grand challenges and formulate specific robust strategies (Ferraro et al., Organization Studies, 2015). This article investigates the practices and mechanisms included in the robust actions and strategies to improve information society assessments (ISA), i.e., measurements of the digital transformation of society. We investigated Cetic.br, a Brazilian ISA organization, to learn how ISA contributes to respond to the grand challenge of digital transformation from a management perspective. Beyond the measurement processes that represent a robust action to tackle the grand challenge of the digital transformation of society, the study of the Cetic.br case help us to improve the understanding on robust strategies implementation to the level of practices and mechanisms comprising them.

Keywords: Digital transformation, Government, Internet, Sustainable development, Climate change, Collaboration.

ArtigosApplication of machine learning techniques in chronic disease literature: from citation mapping to research front

International Journal of Industrial and Systems Engineering, v. 42, n. 2, pp. 193-210. Abstract: This study aims to conduct a hybrid review on applying machine learning techniques in chronic disease literature using both bibliometric and systematic review techniques. The dataset consists of 206 Scopus indexed journal articles from 2004 to 2020. The bibliometric results identify the most contributing authors, journal sources, author network, bibliometric coupling of documents, and the co-citation network. The systematic review reveals the most promising research areas, which include machine learning algorithms integrated with other techniques such as deep learning, artificial neural network, and data mining to predict chronic diseases in gastroenterology, cardiology, and neurology. Although machine learning techniques are rising in popularity in chronic disease literature, there is more room for improvement such as the challenges involved in using machine learning to predict chronic diseases, feasibility studies, and the necessity of rehabilitation and readmission in hospitals to predict a chronic attack.

Keywords: machine learning, chronic disease, diabetes, deep learning, bibliometric analysis, systematic review

ArtigosDívida das famílias, crédito e política monetária

Revista FSA, v. 19, n. 10, pp. 25-44. Resumo: O comportamento da situação financeira das famílias vem despertando grande interesse da sociedade e dos policymakers. Da sociedade em função dos seus efeitos no bem-estar das famílias. Dos policymakers em função da gestão da estabilidade financeira. O artigo buscou apresentar evidências empíricas sobre o comportamento do endividamento das famílias brasileiras frente a mudanças nas condições de crédito e na política monetária no período de março de 2005 a fevereiro de 2020. O presente trabalho preenche uma lacuna da literatura de finanças do Brasil ao estudar os determinantes da situação financeira das famílias brasileiras. Em particular, o trabalho associa política monetária e endividamento das famílias de uma maneira original. No estudo, foram utilizadas séries temporais. As técnicas econométricas empregadas para as estimações foram o método de mínimos quadrados ordinários, métodos generalizados de momentos (GMM) e o sistema de equações via System-GMM. Os resultados do artigo sugerem que a política monetária e as taxas de juros de crédito têm impacto misto sobre a dívida das famílias. Um aumento nas taxas de juros reduz o estoque da dívida, porém aumenta o comprometimento da renda das famílias. Esse resultado sugere uma dinâmica distinta entre o estoque e o fluxo da dívida das famílias, sendo essa a maior contribuição do trabalho.

Palavras-chaves: Endividamento das Famílias. Mercado de Crédito. Política Monetária.

ArtigosThe role of blogs in restoring the self-integrity of women victims of intimate partner sexual violence

Information Technology & People, Vol. ahead-of-print No. ahead-of-print. Abstract Purpose: This paper aims to identify the role of blogs in helping women victims of intimate partner sexual violence to restore their self-integrity. Design/methodology/approach: The authors’ research uses an interpretive stance, supported by motivational and “self” theories to analyze 33 blogs reporting the experiences of women in Brazil who suffered sexual violence perpetrated by an intimate partner. Findings: This study identifies the reasons why women who suffer violence from intimate partners write blog posts. It also develops an analytical framework that bridges the gap between the design and use of IT-artifacts and the context of sexual violence from an intimate partner. Women who suffer violence from intimate partners look for blogs in order to find a safe space for expression, a knowledge hub and a social support network. Blogs play a pivotal role in supporting the journey of reconstructing their self-integrity. Research limitations/implications: The results help to understand the role of blogs in helping victims in vulnerable situations trying to restore their self-integrity. It also contributes to improve the design and functionality of such platforms as an important resource for social support networks. Practical implications: This study shows the positive impact of blogs as a tool to support victims in the process of restoring their self-integrity. Social implications: This study aims to promote the use of digital artifacts such as blogs as a complementary instrument to fight violence against women. Originality/value: The analytical framework used in this paper helps to understand the role of IT-artifacts in the context of sexual violence from an intimate partner.

Keywords: Blogs, Sexual violence against women, Self-affirmation theory.

ArtigosWhat do we know about the relationship between banks and income inequality? Empirical evidence for emerging and low-income countries

Journal of Economics and Business, Vol. ahead-of-print No. ahead-of-print. Abstract: The objective of this article is to examine whether the banking sector contributes to reducing income inequality and poverty. We assess the effect of banks on income inequality considering various banking qualities with a dynamic panel data analysis of 46 emerging markets (EMs) and 66 low-income countries (LICs) using updated data for the 2000–2018 period. The simultaneous and non-linear effects of banking qualities were also evaluated. The results indicate that banking activities (i.e., availability, relevance, and financial efficiency) reduce income inequality and poverty for EMs and LICs. However, there is an optimal degree of each quality mentioned for banks’ impact on inequality beyond which it increases rather than decreases income inequality.

Keywords: Income inequality, Poverty, Banking sector, Financial development, Financial inclusion, Non-linearity, Emerging markets (EMs), low-income countries (LICs).

ArtigosBrazilian Health Care Professionals` Attitudes and Knowledge Regarding Organ Donation and Transplantation: A Systematic Review

Transplantation Proceedings, Vol. ahead-of-print No. ahead-of-print. Abstract Purpose: This systematic literature review synthesizes evidence on Brazilian health care professionals’ attitudes and knowledge regarding organ donation transplantation. Method: This search included 5 databases—EBSCO, PubMed, Web of Science, Scopus, and Virtual Health Library. Search terms were conceptualized into 4 groups—organ transplantation/donation, health care professionals, attitude/knowledge, and Brazil. The eligibility criteria included academic articles that applied quantitative methods to examine the attitudes and/or knowledge of health care professionals toward organ donation-transplantation (ODT). After a critical appraisal of the citations initially retrieved, 13 studies were included in this review. Results: Although most studies pointed to an overall positive attitude of participants toward ODT, insufficient knowledge level among participants was also observed in most studies, especially knowledge gaps regarding aspects such as legal requirements and the functioning of the ODT processes in Brazil. In convergence with the broader ODT literature, education was highlighted as a central point in ODT processes. Conclusion: The results reveal the scarcity of studies on the subject in Brazil and indicate an opportunity for educational efforts to improve the knowledge of health care professionals regarding the ODT process. This study enriches the academic literature and encourages new investigations on the issue, especially in the North and Northeast of Brazil.

ArtigosExtrapolating Long-Run Yield Curves: An Innovative and Consistent Approach

North American Actuarial Journal, Vol. ahead-of-print No. ahead-of-print. Abstract: This article proposes a method to build term structures that are consistent with market data and that provide interest rates for which the volatility, on average, decreases as maturities increase. The method is designed for continuous repetitive use and is consistent with work by Diebold and Li, providing reasonable extrapolated rates, with an appropriate level of volatility over time. The Svensson model is adopted, and its parameters are estimated by the combination of a genetic algorithm and a quasi-Newton nonlinear optimization method. We innovate with a new objective function that focuses on both parts of the estimated curves (interpolated and extrapolated). For this purpose, a stability component is added. The new objective function aims to solve the problem of estimating long-term rates not observable in the market, for which the estimates are usually artificially stable or excessively volatile. The results show that the estimation method is able to bring the volatility of extrapolated rates to levels consistent with those observed for the longest liquid rate. Estimation errors are small enough and there is no statistical evidence that they are biased. The method is useful for the insurance market, since it provides interest rates that do not lead to artificially stable or excessively volatile technical provisions.

ArtigosCaso Queremos! Desafios de uma startup na pandemia

Cadernos EBAPE.BR. Vol. ahead-of-print No. ahead-of-print. Resumo: Criada em 2010, no Rio de Janeiro, a Queremos! surgiu com uma proposta inovadora de aproximar fãs e artistas através de uma estrutura de financiamento coletivo, que possibilitava a viabilização de shows em localidades que normalmente não estariam contempladas nas turnês originais. Após um reposicionamento do modelo de negócios em 2013, a empresa abandona o modelo de crowdfunding que a fez famosa para se especializar na produção de eventos ao vivo, o que lhe possibilitou, além de uma incursão para os EUA entre 2013 e 2016, a expansão da marca com forte presença nas principais capitais brasileiras nos anos seguintes. No entanto, após seu melhor ano em 2019, a empresa foi surpreendida pela pandemia da COVID-19, que afetou drasticamente o setor de entretenimento e live-events no Brasil e no mundo. O caso coloca o leitor no papel dos sócios da empresa, de forma a refletir sobre os desafios estratégicos e operacionais que a Queremos! teve de enfrentar a partir da proibição dos eventos ao vivo devido à pandemia. O caso é indicado para alunos de graduação e pós-graduação de cursos de administração e produção cultural preocupados em discutir temas e conceitos ligados à área de planejamento em tempos de incerteza, análise de risco, gestão da mudança, modelagem de negócios, e inovação em startups.

Palavras-chave: Entretenimento. Live-events.  Modelagem de negócios. Startups. COVID-19.

ArtigosRationales and barriers to citizen participation in public budgeting: a systematic literature review

Revista Brasileira de Ciência Política, n. 39, pp. 1-34. Abstract: This study conducts a systematic literature review on citizen participation in public budgeting, focusing on understanding the rationales of participatory initiatives and the barriers to promoting significant change in public policies. It scrutinizes the data with a mixed-methods approach that involves conducting bibliometric and content analyses and develops analytical propositions to support future studies. The two main rationales of participatory mechanisms political-electoral and good governance – are highlighted, and the barriers to effective citizen participation are discussed. Our findings suggest that to develop participatory innovations it is necessary to consider not only citizens’ capacities to understand public budgeting but also states’ capacities to speak citizens’ language and consider their voices. Future research may benefit from incorporating perspectives from the education field and from integrating technical and political views on public budgeting.

Keywords: Public participation, Public budgeting, SLR, Participatory budgeting, Citizen education, Democratic governance.

ArtigosConstrained portfolio strategies in a regime-switching economy

Financial Markets and Portfolio Management, Vol. ahead-of-print No. ahead-of-print. Abstract: We implement an allocation strategy through a regime-switching model using recursive utility preferences in an out-of-sample exercise accounting for transaction costs. We study portfolios turnover and leverage, proposing two procedures to constrain the allocation strategies: a low-turnover control (LoT) and a maximum leverage control (MaxLev). LoT sets a dynamic threshold to trim minor rebalancing, reducing portfolio turnover, mitigating costs. MaxLev calculates dynamic adjustments to the risk aversion parameter to constrain the portfolio leverage. The MaxLev adjustments depend on the risk aversion and permitted portfolio leverage, which enables optimal strategies considering the leverage constraints. The study uses US equity portfolios, and shows that, first, models with LoT result in superior return-to-risk measures than those without it when transaction costs increase. Second, considering transaction costs, the return-to-risk measures of the models using MaxLev closely match or exceed those from the corresponding unconstrained regime-switching benchmarks. Third, MaxLev returns have lower volatility and higher return-to-risk than conventional numerically constrained benchmarks. Fourth, the certainty equivalent returns indicate that models using MaxLev and LoT outperform both single-state models and unconstrained regime-switching models with statistical significance.

Keywords: Regime switching models, Dynamic asset allocation, Stochastic differential recursive utility, Analytical solutions, Transaction costs, Leverage and turnover constraints.

ArtigosThe effect of capital structure, operating efficiency and non-interest income on bank profitability: new evidence from Asia

Asian Journal of Economics and Banking, Vol. ahead-of-print No. ahead-of-print. Abstract Purpose: The Asian banking system has been appreciated with many distinct qualities including consistent in profitability. Many studies have examined the profitability of Asian banking sector from diverse perspectives. However, studies on bank profitability in connection to the capital structure, operating efficiency and non-interest income are only a few. This study investigates the influence of capital structure as estimated by leverage ratio and long-term debt, operating efficiency and non-interest income on the profitability of the banking industry in 28 countries of Asia. Design/methodology/approach: This paper utilizes fixed effect regression model by involving panel data with sample of 492 banks from 28 countries of Asia for the time span of 15 years from 2004 to 2018. Findings: The results confirm that an increase in total debt ratio increases the profit margin of the bank as supported by the agency cost theory, suggesting that the debt financing increases the profitability of the firm. In addition, the findings reveal that lowering the operating expenses and managing of costs effectively can boost the profitability of bank. Furthermore, non-interest income plays a vital role when the interest rates are lower. Hence the study suggests that a careful investment in this sector can generate income as well as increase the profit margin of the banking arena. Originality/value: The paper examines the profitability of bank by including impact of leverage ratio and long-term debt as a measure of capital structure along with the influence of operational efficiency and non-interest income which contributes to the understanding of the existing literature.

Keywords: Capital structure, Operating efficiency, Non-interest income, Asia.

ArtigosStochastic network DEA-R models for two-stage systems

Journal of Modelling in Management, Vol. ahead-of-print No. ahead-of-print. Abstract Purpose: This paper aims to present two-stage network models in the presence of stochastic ratio data. Design/methodology/approach: Black-box, free-link and fix-link techniques are used to apply the internal relations of the two-stage network. A deterministic linear programming model is derived from a stochastic two-stage network data envelopment analysis (DEA) model by assuming that some basic stochastic elements are related to the inputs, outputs and intermediate products. The linkages between the overall process and the two subprocesses are proposed. The authors obtain the relation between the efficiency scores obtained from the stochastic two stage network DEA-ratio considering three different strategies involving black box, free-link and fix-link. The authors applied their proposed approach to 11 airlines in Iran. Findings: In most of the scenarios, when alpha in particular takes any value between 0.1 and 0.4, three models from Charnes, Cooper, and Rhodes (1978), free-link and fix-link generate similar efficiency scores for the decision-making units (DMUs), While a relatively higher degree of variations in efficiency scores among the DMUs is generated when the alpha takes the value of 0.5. Comparing the results when the alpha takes the value of 0.1–0.4, the DMUs have the same ranking in terms of their efficiency scores. Originality/value: The authors innovatively propose a deterministic linear programming model, and to the best of the authors’ knowledge, for the first time, the internal relationships of a two-stage network are analyzed by different techniques. The comparison of the results would be able to provide insights from both the policy perspective as well as the methodological perspective.

Keywords: Data envelopment analysis, DEA-R, Two-step network, Random data, DEA, Efficiency analysis.

ArtigosA novel hierarchical fuzzy inference system for supplier selection and performance improvement in the oil & gas industry

Journal of Decision Systems, Vol. ahead-of-print No. ahead-of-print. Abstract: Evaluation of suppliers is essential to increasing competitive power, customer satisfaction, and profitability. Oil and gas companies can use this research to evaluate suppliers and map the potential path forward for future collaborations. Six supply chain managers in Iran designed HFIS for the oil and gas industry. Shannon Entropy was used to determine the relative weights of suppliers concerning overall uncertainty because the Oil and Gas industry uses many unstructured Key Performance Indicators (KPIs). Using Matlab Toolbox FIS, a future cooperation roadmap was developed. Experts suggested future collaboration with certain suppliers based on the HFIS results. The future cooperation strategy proposed by the framework is highly in line with their expectations. FIS results indicate that the proposed can help select the most appropriate suppliers for cooperation while providing a roadmap for weaker suppliers to improve their performance.

Keywords: Fuzzy inference system (FIS), supplier selection, Shannon entropy, Kraljic portfolio purchasing model, oil & gas (O&G) industry.

ArtigosAn integrative review on online ethnography methods: differentiating theoretical bases, potentialities and limitations

Qualitative Market Research, v. 25, n. 4, pp. 492-510. Abstract Purpose: As a result of the advancement of the online environment, several methodological proposals emerged to establish procedures for digital qualitative research. While the various online ethnography methods overlap, they are not equivalent in terms of their theoretical bases, procedures and goals. The purpose of this article is to add clarity to their main differences, depicting specificities, potentialities and limitations of each method. Design/methodology/approach: This conceptual article results from an integrative literature review that brought together studies that proposed, debated or used qualitative research methods in the digital environment. The research focused on the primary indexed journals publishing cultural studies in the past 20 years. Findings: The literature review highlights four methods – virtual ethnography, digital ethnography, netnography and the post-application programming interface ethnography. The integrative literature review adds clarity depicting the main premises and procedures of each method. The present analysis positions the different methods considering two dimensions: the focus on the boundaries of the group/culture investigated, and the focus on the platform agency, affordances and specific dynamics. Originality/value: The article proposes a comparative framework outlining points of convergence and divergence to create a reference for researchers on topics of significance while designing and conducting a research study in a digital environment. This conceptual organization highlights and supports qualitative researchers on their methodological challenges.

Keywords: Qualitative research, Online ethnography, Virtual ethnography, Digital ethnography, Netnography, Post-API ethnography, Integrative literature review.

ArtigosDiamond of the desert: The case of Qatar’s 2022 FIFA World Cup

Tourism and Hospitality Management, v. 28, n. 2, pp. 471-493. Abstract: For the first time in the Arab world, the FIFA World Cup in Qatar 2022 was one of the main drivers for promoting important infrastructural changes in the country, as well as for transforming the image of Qatar in order to make the destination more attractive to foreign tourists. However, despite the great wealth from its Oil & Gas reserves, several social challenges that historically affect the country began to emerge due to greater coverage of the international media, threatening the expectations of positive legacies left on the country’s image from the event. Given this context, the case puts the reader in the role of Ahmed Al-Nasr, then Chairman of the Qatar Supreme Committee for Delivery and Legacy, as he faces different pressures made by major international brands sponsoring the event who now see their image threatened by successive controversies that the country has been involved in and they are threatening to withdraw their support and investments. The case is indicated for undergraduate and graduate students of courses in the area of Tourism, Sport Management, and Business interested in discussing topics and concepts related to environmental, social, and governance (ESG) responsibility, management of mega events, international marketing, and country destination image.

Keywords: ESG, Mega Sporting Events, Destination Image, FIFA World Cup.

ArtigosEvaluation of Multi-stage Fuzzy Networks in DEA and DEA-R Based on Liquidity Ratios with Undesirable Outputs

International Journal of Fuzzy Systems, v. 24, pp. 2411-2426. Abstract: In this paper, radial models of multi-stage fuzzy DEA and DEA-R networks are first proposed based on liquidity ratios with desirable and undesirable outputs for evaluating a set of decision-making units (DMUs). Second, non-radial models are proposed based on the Slacks-Based Measure of Inefficiency (SBMI) and a Directional Non-Radial (DNR) model. On the one hand, the similarity of DEA and DEA-R models, as well as adherence to the axioms in constructing the production possibility set (PPS), has provided the possibility to model the restrictions of the aforementioned models; on the other hand, for efficiency calculation, different objective functions (radial and non-radial) have been used in a multi-stage network structure with fuzzy data. The models proposed for calculating the efficiency of the first, second, and third stages, as well as the overall network, in multi-stage networks therefore take the form of a fuzzy linear programming model that has been converted into linear programming. The advantage to the present article, aside from the linearity of the multi-stage fuzzy network models, is that we can model the corresponding models in DEA and DEA-R-based purely on liquidity ratios with desirable and undesirable outputs. Finally, focusing on a multi-stage network in the Iranian education system while considering fuzzy data, the efficiency and inefficiency of the DMUs are calculated based on liquidity ratios with desirable and undesirable outputs. It can be observed that in the SBMI model, the overall efficiency scores in DEA and DEA-R models are 58% and 45%, respectively.

Keywords: Data envelopment analysis, Fuzzy data, Liquidity ratios, DEA-R, α-Cut, Undesirable output.

ArtigosEvidence from multiple countries: does investment into internal corporate social responsibility improve firm efficiency?

Journal of Sustainable Finance & Investment, Vol. ahead-of-print No. ahead-of-print. Abstract: This paper investigates the relationship between internal corporate social responsibility (ICSR) and firm efficiency. Our research employed a two-stage analysis of 33,413 firm-year observations from between 2008 and 2020. First, we measured the level of firm efficiency using data envelopment analysis (DEA). Second, we used panel regression to investigate the impact of investments made by firms into ICSR on their efficiency. Our results showed that such investments into ICSR (e.g. on employee development) increased firm efficiency during the study period.

Keywords: Internal corporate social responsibility, Firm efficiency, Data envelopment analysis.

ArtigosA generalized inverse DEA model for firm restructuring based on value efficiency

IMA Journal of Management Mathematics, Vol. ahead-of-print, No. ahead-of-print. Abstract: We present a novel general inverse data envelopment analysis model for assessing the restructuring of decision-making units (DMUs) while observing predetermined value efficiency targets, under two distinct scenarios: merger and acquisitions and split. By considering the set of efficient DMUs as the Decision Maker’s set of Most Preferred Solutions, virtual new units with desired targets for value efficiency scores and input and output levels can be computed. The innovations of this paper are threefold. First, a comparison between the proposed value efficiency and previous technical efficiency approaches reveals improvement in the estimation of restructured input/output levels. Second, the proposed approach is capable of handling the decision-maker’s preferences during restructuring. Third, an algorithm to determine the worst case-scenario for restructuring is presented. An applied case study in banking operations is presented to illustrate the validity and applicability of the proposed method.

Keywords: Inverse DEA, Value efficiency, Generalized model, Restructuring, Preference targets.

ArtigosA novel slacks-based model for efficiency and super-efficiency in DEA-R

Operational Research, v. 22, n. 4, pp. 3373-3410. Abstract: In this paper we present a new model combining the major underlying ideas behind the Slacks-Based Measure (SBM) and the Data Envelopment Analysis-Ratio based (DEA-R) models. This new proposed model computes efficiency and super-efficiency scores based on the corresponding slack values for both input/output and output/input ratios, depending upon the orientation of the production frontier. A comprehensive step-by-step derivation of the SBM-DEA-R model in light of previous approaches is offered to readers. Besides, in order to show the validity of the approach proposed in light of the current body of literature, we revisit a case study of twenty-one medical centers in Taiwan. Limitations and directions for future research are discussed.

Keywords: DEA, SBM, Ratio data, Efficiency, Super-efficiency.

ArtigosSocial welfare and bank performance: evidence from a stochastic neural hybrid MCDM approach

Journal of Economic Studies, vol. 49, n. 7, pp. 1137-1158. Abstract Purpose: This paper investigates the endogenous relationships between banking performance and social welfare in Southern African Development Community (SADC) countries. Design/methodology/approach: A comprehensive three-stage multi-criteria decision-making (MCDM) approach based on alternative informational assumptions is applied. Findings: Results indicate that banking performance is paradoxically associated with stagnant economic activity and higher wealth concentration for the minority. The authors found that SADC banking performance promotes higher Human Development Index (HDI) standards possibly via efficient financial intermediation, dissemination of best managerial practices and other forms of positive spillovers in these countries. Originality/value: This paper contributes to the MCDM literature by simultaneously exploring the key concepts of “utility functions” (using COPRAS) and “distance to ideal solutions” (using TOPSIS) in mapping and explaining the feedback and cause-effect processes between banking performance and social welfare that may exist. Another distinctive aspect is related to the computation of bias-free criteria weights, using a robust SWARA order-rank based on information entropy. Finally, this paper is concerning the endogeneity measurement, using a novel stochastic structural relationship non-linear programme.

Keywords: COPRAS, Multi-criteria decision-making, TOPSIS, SWARA, Banking performance, Social welfare.

ArtigosFinancial and fiscal incentives and inward foreign direct investment: When quality institutions substitute incentives

Journal of International Business Policy, Vol. ahead-of-print, No. ahead-of-print. Abstract: We analyze the impact of host country investment incentives on inward foreign direct investment. Building on institutional economics, we argue that financial and fiscal incentives are effective in attracting greenfield projects because they reduce the short-term establishment and long-term operational costs, respectively. We also propose that the effectiveness of the incentives varies with the institutional quality of the host country because institutional quality reduces the indirect cost of transacting in the location; thus, quality institutions have the potential to act as substitutes for incentives. The analysis of greenfield projects in 106 countries in 2010–2017 reveals that although financial and fiscal incentives have a positive impact on greenfield investments when studied separately, financial but not fiscal incentives are effective in attracting greenfield projects when analyzed together. This is a novel finding as much of the literature has concentrated on studying one type of incentive at a time. Additionally, we find that financial incentives are more effective in attracting greenfield projects in countries with high-quality institutions, while fiscal incentives are more effective in countries with low-quality institutions. Policymakers may want to concentrate on creating high-quality institutions not only because of their direct effect in attracting foreign investments, but also because they substitute for the need to provide incentives to attract foreign direct investment.

Keywords: Inward foreign direct investment, Fiscal incentives, Financial incentives, Greenfield projects, Institutions.

ArtigosCOVID-19, sustainability and Olympic Games: which lessons can we learn from Tokyo 2020?

Sport, Business and Management, Vol. ahead-of-print, No. ahead-of-print. Abstract Purpose: This paper aims to understand how the sustainability theme has been incorporated into the new Olympic planning guidelines based on analysing the case of Tokyo (2020), which was severely impacted by the COVID-19 pandemic. Design/methodology/approach: For this, field research using the case study method was carried out that involved 21 in-depth interviews with experts from different entities affected by the event. Findings: As a result, it was possible to identify that some characteristics already presented in the Tokyo project came to break away from the gigantism observed in the past Olympic editions in an attempt to demonstrate alignment with the new principles brought by the IOC (2020) and 2020 + 5 Agenda that had as one of its main objectives to simplify the Olympics, making the event more sustainable and accessible for future host societies. Originality/value: At the end, some trends for the future of the Olympic Games are also presented in order to guide future studies in the area, as well as help the future host cities and their companies in planning their investments.

Keywords: Olympic games, Tokyo 2020, COVID-19, Mega sporting events, Sustainability.

ArtigosDoes the Olympic legacy and sport participation influence resident support for future events?

Leisure Studies, v. 41, n. 4, pp. 471-486. Abstract: This study aims to explore and describe the structural relationships among (a) perceptions of Olympic legacy, (b) sport participation in the community and (c) resident support towards future events. A field study was conducted in Rio de Janeiro five-year post-Games, and data were collected from local residents who lived in the Olympic city using an online questionnaire (n = 400). A confirmatory factor analysis (CFA) analysed the psychometric properties of the constructs, and a subsequent structural equation model (SEM) examined the relationships between the constructs. Results indicated that the Olympic legacy can positively influence sport participation in the community and its support for future events. In addition, the findings also confirmed the predictive power of the community sport participation on the support behaviours, suggesting its inclusion in future models. Implications focus on effective synergies of political, sportive and social participation to enhance the local support level in the host community.

Keywords: Olympic legacy, Sport participation, Support future events, Local community, Rio de Janeiro.

ArtigosBank efficiency estimation in China: DEA-RENNA approach

Annals of Operations Research, v. 315, n. 2, pp. pages1373–1398. Abstract: The current study proposes a new DEA model to evaluate the efficiency of 39 Chinese commercial banks over the period 2010–2018. The paper also, in the second stage, investigates the inter-relationships between efficiency and some bank-specific variables (i.e. bank profitability, bank size, expenses management, traditional business and non-traditional business) under the Robust Endogenous Neural Network Analysis. The findings suggest that the sample of Chinese banks experiences a consistent increase in the level of bank efficiency up to 2015; the efficiency score is 0.915, after which the efficiency level declines and then experiences a slight volatility, while finally ending up with an efficiency score of 0.746 by the end of 2018. We also find that among different bank ownership types, the state-owned banks have the highest efficiency, the rural commercial banks are found to be least efficient and the foreign banks experience the strongest volatility over the examined period. The second-stage analysis shows that bank size exerts a positive influence on the development of non-traditional banking business and a proactive expense management, bank size and non-traditional businesses have a positive impact on efficiency levels, while bank profitability, traditional businesses and expenses management have negative influences on bank efficiency.

Keywords: DEA, Robust endogenous neural network analysis, Banking, China.

ArtigosInstitutional theory and outward foreign direct investment: a review and future directions

European Journal of International Management, Vol. ahead-of-print, No. ahead-of-print. Abstract: This study aims to map what we know and what we do not know concerning both the institutional theory and OFDI in order to elucidate how this subject has been treated in the international business arena and how it could help us to understand not only the emerging markets phenomena, but also how institutions and OFDI can open new research venues to the understanding of IB. To do so, we reviewed 140 papers concerning the relationship between institutions and OFDI. By applying both keyword co-occurrence and content analysis, our review showed that the main researches are distributed into five sub-fields: government support, location choice, market strategy, political institutions, and specific advantages. This article not only maps studies, but also shows underexplored research streams and how each one impacts the IB studies. Additionally, our study can help develop future studies by pointing out research gaps.

ArtigosContact tracing: Achieving equilibrium between blockchain solutions and privacy amid the novel coronavirus pandemic

Journal of Information Technology Teaching Cases, v. 12, n. 2, pp. 194-205. Abstract: In moments of scepticism and hopelessness, the drive to satisfy collective needs pushes humanity to accomplish incredible feats to ensure our survival on earth. Indeed, the current global crisis caused by the novel coronavirus is no exception. We are struggling with the abrupt spread of this illness and continuously striving to find efficient solutions. This has been André Salem Alégo’s primary inspiration since the crisis hit his country in March 2020. He is the chief executive officer of Blockforce, a blockchain-based SocialTech. Having observed the effects of novel coronavirus, André examined various approaches that could help contain the spread of the virus and keep society safe. He came up with the idea for an innovative service called Desviralize, which supports pandemic crisis monitoring through contact-tracing with the use of blockchain technology. This teaching case covers how an emergent technology evolves amid the pandemic. It draws attention to important facts related to the digital era such as data security and privacy in the context of Desviralize and Blockforce’s chief executive officer’s strategies for boosting platform growth within the constraints imposed by data protection regulation, the critical pandemic situation, and the ethical aspects of the application of technology.

Keywords: Blockchain, GDPR, GDPL, COVID-19, Contact tracing, SocialTech, Privacy.

ArtigosDigitalization and collaborative dynamics integrating artistic, technological and co-creative resources: the case of Postmodern Jukebox

International Journal of Entrepreneurial Behavior & Research, Vol. 28, No. 8, pp. 2024-2048. Abstract: Purpose: This work investigates how digital technologies and artistic resources interact in order to bring different Creative and Cultural Industry (CCI) actors together in networks. As the stage of this work, the authors investigate the musical collective Postmodern Jukebox (PMJ), a digital-based enterprise which is intensive in the use of social media platforms. Design/methodology/approach: The study adopts a qualitative approach, based on a case study and netnography. Findings: The findings demonstrate how the technology available to CCI enterprises can be used to leverage business through the engagement of its audience in collaborative processes. The analysis also evidences collaborative dynamics resulting from the integration of three key operant resources in CCI: artistic, technological and co-creative resources. Finally, the case shows the role of a CCI enterprise as an engagement platform that capture people’s emotions trough artistic content. Originality/value: From a managerial perspective, the study demonstrates how a digital CCI enterprise manages the flow of resources and knowledge drawn from several networks in order to engage actors in co-creating value. Our analysis also suggests that emotions are not only drivers in bringing actors closer to the value cocreation process but also collectively created outputs within these interactions. In this process, the artistic resources of CCI’s enterprises play a fundamental role in capturing and transforming these emotions by putting actors from different networks in contact.

Keywords: Digital entrepreneurship, Cultural and creative industry, Case study, Netnography, Nostalgia network.

ArtigosResilience of Brazilian health-care professionals during the pandemic

International Journal of Quality and Service Sciences, v. 14, n. 3, pp. 383-401. Abstract: Purpose: Health-care professionals are caring for patients in unprecedented circumstances during the COVID-19 pandemic, dealing with scarce resources, higher demand and uncertain outcomes. In this context, the purpose of this study is to explore the views of health-care professionals regarding their work conditions and perceived impacts of the pandemic on their health, as well as the role of resilience and improvisation in face of the new challenges. Design/methodology/approach: This exploratory and qualitative study carried out semi-structured interviews with eleven health-care professionals from three Brazilian states that have been working in intensive care settings during the pandemic. Findings: The pandemic has posed a great personal and professional burden on the professionals, impacting their physical and mental health. It also has required them greater resilience and improvisation capabilities to adequately perform work-related activities. Practical implications: In addition to individual-level attitudes, the results suggest that aspects in the government, society, personal relationships and providers domains influence the effects of the pandemic on the health-care professionals and how they cope with the ongoing crisis. Such a multifactorial approach should therefore be considered by health managers. Originality/value: With no similar effort identified, this study emphasizes the relevance of discussing the pandemic burden on frontline professionals and intends to be useful for health practitioners, managers, academics and policymakers.

Keywords: Qualitative research, Professionals, Crisis management, Health-care management.

Artigos‘If I hadn’t seen this picture, I’d be smoking’—perceptions about innovations in health warnings for cigarette packages in Brazil: a focus group study

Tobacco Control, Vol. ahead-of-print No. ahead-of-print.  Abstract: Objective: To investigate the perceptions of young people and adults, smokers and non-smokers about the current set of innovations introduced in 2018 into the Brazilian tobacco products’ health warnings. Methods: Twenty focus groups were conducted in five state capitals in Brazil. The participants (n=163) were segmented by smoking status, age (15–17 years, 18–55 years) and social grade (C, D–E classes) to examine cigarette packaging and explore the participants’ perceptions of health warnings. Results: Health warnings capture attention, eliciting apprehension, fear, disgust and concern about the negative consequences of cigarette consumption. The 2018 Brazil health warnings are spontaneously recalled by participants, even without the presence of cigarette packages. However, the analysis also reveals the challenges of overcoming communication barriers and distorted interpretations, especially among smokers. The inclusion of direct and provocative stimuli, such as the use of the word ‘you’, attracts attention and creates more proximity to the recipient of the message. The results also highlight the interest and fear elicited by warnings on toxic constituents and the importance of using contrasting colours in warnings, which differentiate them from the colours of cigarette packs. Conclusion: Introducing innovative components in health warnings can catch consumers’ attention but considering that the interviewees encountered difficulties interpreting textual warnings about toxic constituents in cigarettes, the study reinforces the importance of adopting direct language and pictures, instead of text, which can visually transmit the warning messages and the use of specific wording that generates proximity between the emitter and receiver.

ArtigosMarket reaction to political risk: Evidence from the 2018 Brazilian presidential election

Latin American Business Review, Vol. ahead-of-print, No. ahead-of-print. Abstract: The 2018 Brazilian presidential elections coupled unprecedented political instability with a close race between two candidates with antagonistic economic agendas. Using this unparalleled scenario, this paper analyzes the role of political events in shaping the returns on financial assets. The regressions using the Propensity Score Matching technique suggest that companies linked to the government had positive cumulative abnormal returns around relevant events compared with otherwise identical firms. These results reinforce the role of political risk on financial markets in emerging economies and allow economic agents to outline strategies to predict stock return behavior during periods of political turmoil.

Keywords: Electoral risk, Event study, Political risk, Propensity score matching, State control, Stock return.

ArtigosEthics position of Brazilian workers: An International Comparative View

Latin American Business Review, Vol. ahead-of-print, No. ahead-of-print Abstract: This article explores Brazilian workers’ ethics position and compares it to those of other nations. We surveyed 410 Brazilian workers and used the Ethics Position Questionnaire (EPQ), with idealism and relativism scales. We translated, back-translated, and adapted the scales according to Sperber and conducted exploratory factor analyses together with confirmatory factor analyses to validate them. The results show that Brazilians present, on average, high idealism and low relativism. Therefore, Brazil appears to be a well-defined “absolutist” country compared to other nations, a surprising outcome, since Brazil ranks as one of the most corrupt countries on international scales.

Keywords: Brazil, Corruption, Ethics position, Idealism, Relativism.

ArtigosThe Macroeconomic Impact on Bank’s Portfolio Credit Risk: The Colombian Case

Emerging Markets Finance and Trade, Vol. ahead-of-print, No. ahead-of-print. Abstract: This paper explores the determinants of credit risk for the Colombian economy, a small emerging economy in Latin American. Using a sample of 28 large banks over the 2009–2019 period and the dynamic data panel approach, we find that the macroeconomic environment’s deterioration affects the credit risk perception held by banks as measured through non-performing loans and loan loss provisions. On the other hand, a better political environment brought about by peace accords smoothed such an impact. Estimates indicate different reactions when distinguishing by loan type. Business credit depends heavily on unemployment, while consumer credit risk is more sensitive to the interest rate. In the case of mortgage loans, economic growth and the unemployment rate are the most critical variables to mitigate risk. These results shed light on the impact of the economic environment on credit lines with different features.

Keywords: Credit risk, Banking, Emerging economies.

ArtigosEl SPREAD de las tasas de interés en Colombia para el período 2010-2020

Lecturas de Economia, n. 97. Resumen: El SPREAD mide los costos de intermediación del sistema financiero y afecta el crecimiento económico. Este artículo busca evaluar los determinantes del SPREAD para la economía colombiana bajo el esquema de inflación objetivo durante el período 2010-2020. Para ello, utiliza la metodología de panel de datos dinámico y estima varios modelos con el método de momentos generalizados (GMM). Los resultados muestran que el entorno macroeconómico —en especial el desempleo— y la eficiencia operacional de las instituciones financieras, son factores importantes para explicar el SPREAD. Además, la concentración de mercado del sistema financiero también es relevante para entender el comportamiento de los costos de la intermediación.

ArtigosState-level educational performance in Brazil: A MCDM approach taking a governance perspective

Journal of Multi-Criteria Decision Analysis, v. 29, n. 3/4, pp. 199-217. Abstract: This study presents an educational performance assessment of Brazilian state-level units using the technique for order preference by similarity to the ideal solution (TOPSIS). Although this technique is a well-established multi-criteria decision making (MCDM) model that can be applied across diverse areas, it has yet to be applied to an analysis of primary and secondary education. We assess how state-level units in Brazil perform in terms of primary and secondary educational inputs and outputs during the period from 2013 to 2017. We handle epistemic uncertainty with regard to weight definition using maximal information entropy. Additionally, a Tobit regression approach on performance scores is developed. Results show that region of the country plays an important role in determining educational performance. Moreover, results indicate that gross domestic product (GDP) is positively related to education scores while infant mortality is negatively associated with educational performance.

Keywords: Educational performance, Information entropy, Tobit, TOPSIS.

ArtigosConsumer Grief: understanding how consumers deal with the loss of extraordinary experiences

Cadernos EBAPE.BR, v. 20, n. 3, pp. 339-351. Abstract: Despite the interest in the role of consumption in the bereavement process, the concept of consumer grief and the process consumers experience when grieving remain undertheorized. This article aims to conceptualize consumer grief considering the disruption brought by the COVID-19 pandemic and the need to understand how consumers respond to this scenario, understanding the mechanisms consumers create to deal with loss. In view of the importance of extraordinary experiences due to their embodied, social, and transformational power, in this netnographic study, we explore marathon runners’ loss of an extraordinary experience. Consumers deal with the loss of an experience through a process composed of five mechanisms mediated by social media, which enable consumers to reverse, reframe, and reestablish the experience. The mechanisms of refutation, despair, abstention-compensation, transgression, and acceptance show how consumers behave in different moments of grief, allowing them to build their trajectories in the grieving process, individually and collectively. As a contribution, we expand the literature on consumer grief by focusing on the specific concept of consumer grief, explaining the processes consumers go through when they deal with the loss of an experience. Additionally, we present a collective perspective on the grieving process, shifting the analysis of the grief of an individual or a family unit to the socialization of grief.

Keywords: COVID-19, Consumer Grief, Grief, Extraordinary Experience.

ArtigosDelivering blood components through drones: a lean approach to the blood supply chain the blood supply chain

Supply Chain Forum: An International Journal, v. 23, n. 2, pp. 113-123. Abstract: This research explores how drones can improve the blood supply chain (BSC) in the delivery of blood components. This analysis is done considering the lean principles, and the aim is to understand challenges and wastes present in the BSC and map the drone advantages. Through a literature review and the use of in-depth interviews, data is collected from seven BSC experts. Main challenges were identified related to high wastage level, ability to predict demand for blood, low level of centralisation in developing countries, unexpected short-term changes in demand, and sanitary, environmental, and infrastructural risks. Wastes were identified mainly due to improper temperature during transportation, compromising blood bags’ safety, lack of equipment maintenance, leading to higher depreciation rates, and waiting time for the delivery of biomolecular testing results. The use of drones can represent gains in delivery time, allowing a ‘just-in-time’ model of distribution of blood, operating through a ‘pull’ system, reducing the need for inventories and costs.

Keywords: Blood supply chain, Drones, blood distribution, Lean principles.

ArtigosImplementation of Sustainable Supply Chain Management considering Barriers and Hybrid Multiple-Criteria Decision Analysis in the Healthcare Industry

Mathematical Problems in Engineering, v. 2022. Abstract: This research aims to find the barriers that affect the implementation of sustainable supply chain management (SSCM) and rank them using hybrid multiple-criteria decision analysis (MCDA) methods in the healthcare industry. As companies seek to earn revenue by providing goods or services to customers, they must also consider social responsibility, economics, and the environment as other multiple external factors. One of the most crucial factors is the company’s stewardship of the environment, but economic factors must be regarded when keeping the environment clean by balancing the economic situation to make a profit. This study extracts the barriers to implementing SSCM from previous studies, adapts these barriers to the healthcare industry, and ranks them using a hybrid best-worst method (BWM) and combined compromise solution (CoCoSo) method. The result indicates that hospital 7 should rank SSCM higher than the other six healthcare centers evaluated. Moreover, among the barriers, high disposal costs is the most crucial factor when considering implementing SSCM.

ArtigosEnergy efficiency in production of swiftlet edible bird’s nest

Sustainability, v. 14, n. 10, pp. 5870. Abstract: The swiftlet edible bird’s nest (EBN) is a ranching industry in which the ranchers do not have to own the birds and are not required to prepare the food as the birds will find their own. However, the ranchers need to provide the ranches and attract the birds for nesting. This study examined a two-stage analysis on energy efficiency and greenhouse gas (GHG) emission in the swiftlet EBN production in Johor Bahru, Johor, Malaysia. In the first stage, non-parametric data envelopment analysis (DEA) was used to measure the efficiency score. The results revealed that out of 150 ranches, 7.33% and 40.67% of the ranches were efficient under the Charnes, Cooper, and Rhodes (CCR) and Banker, Charnes, and Cooper (BCC) models, respectively. The average of technical, pure technical, and scale efficiencies are 0.35361, 0.93071, and 0.37199, respectively. Analysis on optimum energy requirement and energy savings showed the total energy input that could be saved by the inefficient ranches was 0.89391 MJ/sqft−1 (63.87%). In addition, the inefficient ranches could reduce emissions by 63.86% (0.04497 kg Co2eq/sqft−1). In the second stage of analysis using the Tobit model, the results reported that a nesting plank was the factor with the most significantly positive effect on the ranch efficiency to improve their efficiency in energy consumption savings and emissions reduction in the EBN production.

Keywords: Swiftlet edible bird’s nest, Data envelopment analysis, Energy efficiency, Greenhouse gas emission.

ArtigosRevisiting CAMELS Rating System and the Performance of ASEAN Banks: A Comprehensive MCDM/Z-Numbers Approach

IEEE Access, v. 10, pp. 54098 – 54109. Abstract: This paper provides a new perspective on the performance of ASEAN member countries’ banks as proxied by CAMELS rating system in the light of information reliability. A comprehensive MCDM approach is developed based on alternative methods to handle expert preference uncertainties regarding banking ideal performance levels and relative CAMELS variable efficiency. While expert preferences are collected using structured interviews, the partial bank rankings are defined upon Fuzzy TOPSIS with the primary relative efficiency weights obtained from SWARA. Z-numbers are utilized to address the inherent fuzziness in how banking performance and financial distress are associated with information reliability of positive-ideal banking performance and CAMELS variables efficiency functions generated from expert preferences or perceptions. The empirical findings demonstrated that employing information reliability methodologies applied to a proxy of the CAMELS rating system, the ambiguous influence of ASEAN banking performance on financial hardship can be adequately handled.

ArtigosAntecedents of perceived service quality of online education during a pandemic: configuration analysis based on fuzzy-set qualitative comparative analysis

Evaluation Review, v. 46, n. 3, pp. 235-265. Abstract Background: During COVID-19 lockdown worldwide, classroom education continues remotely through online. The question remains, comparing with the face-to-face education, does online education has a similar satisfaction level among the students? There are only a few studies that examine the perceived service quality of online education. Objective: The study aims to analyze the factors of perceived service quality of online education during a pandemic. Research Design: A structured questionnaire elicits information from 147 students from different study backgrounds of various universities worldwide. The fuzzy-set qualitative comparative analysis (fsQCA) is used for data analysis and model design. Research constructs evaluation for reliability and internal consistency are subsequently performed. A snowball random sampling method is applied for data collection. Results: Findings from the fsQCA analysis identify four core factors that underpin student satisfaction through positive perceived service quality of online education. Alternative paths are determined based on gender, students’ current education status, and their loyalty toward online education. We also introduce two topologies of perceived quality regarding online education and student satisfaction. Originality: Because of the primary nature of the data, this is firsthand experience gathered from different universities around the world who have willingly or unwillingly experienced online learning during the pandemic. The fsQCA technique for examining perceived service quality of online education. Conclusions: The findings contain a number of contributions, illustrating different topologies of the student from different backgrounds and their intention, satisfaction and loyalty towards e-learning, and identifying causal factors that influence willingness to recommend online education.

Keywords: Perceived service quality, Online education, Fuzzy-set qualitative comparative analysis, Pandemic.

ArtigosThe impact of social welfare and COVID-19 stringency on the perceived utility of food apps: A hybrid MCDM approach

Socio-Economic Planning Sciences, v. 82, Part B. Abstract: The COVID-19 pandemic has created enormous challenges for society due to the various ways of impacting health. This paper focuses on the impact of the COVID-19 pandemic on people’s food consumption patterns in the online environment. We investigate food app reviews and examine whether countries with a high rate of success with COVID-19 control consume more unhealthy food through mobile apps. We also investigate whether the population of countries with low social welfare eat more unhealthy food during the COVID-19 pandemic compared to countries with high social welfare. We take a hybrid multi-criteria decision making (MCDM) approach to calculate indexes based on the technique for order of preference by similarity to an ideal solution, complex proportional assessment, and VlseKriterijuska Optimizacija I Komoromisno Resenje. Results show that country social welfare and success in COVID-19 control negatively affect the perceived utility of the apps. Also, success in COVID-19 control and the perceived utility of food apps positively affect the proportion of unhealthy reviews, whereas social welfare has a negative impact. The results have important implications for public health policymakers, showing that the online food environment can be an important setting for interventions that seek to incentivize healthy eating.

Keywords: Online environment, Food consumption, Unhealthy food, COVID-19 control, Social welfare, MCDM.

ArtigosPortfolio Optimization with a Mean-Entropy-Mutual Information Model

Entropy (Basel), v. 24, n. 3, pp. 369. Abstract: This paper describes a new model for portfolio optimization (PO), using entropy and mutual information instead of variance and covariance as measurements of risk. We also compare the performance in and out of sample of the original Markowitz model against the proposed model and against other state of the art shrinkage methods. It was found that ME (mean-entropy) models do not always outperform their MV (mean-variance) and robust counterparts, although presenting an edge in terms of portfolio diversity measures, especially for portfolio weight entropy. It further shows that when increasing return constraints on portfolio optimization, ME models were more stable overall, showing dampened responses in cumulative returns and Sharpe indexes in comparison to MV and robust methods, but concentrated their portfolios more rapidly as they were more evenly spread initially. Finally, the results suggest that it was also shown that, depending on the market, increasing return constraints may have positive or negative impacts on the out-of-sample performance.

Keywords: Portfolio optimization, Entropy, Mutual information, Variance and covariance.

ArtigosMeasuring higher education performance in Brazil: government indicators of performance vs ideal solution efficiency measures

International Journal of Productivity and Performance Management, v. 71, n. 6, pp. 2479-2495.Abstract Purpose: This study extends the educational institutions’ performance and efficiency literature by examining Brazil’s Federal Institute of Education, Science and Technology (FIEST), which consists of educational units throughout the country that span several levels of education. Design/methodology/approach: The authors build and analyze a covariance matrix consisting of both a group of efficiency measures and a group of performance indicators used by Brazil’s Ministry of Education (BME). The values in the covariance matrix are maximized through application of the Technique for Order of Preference by Similarity to the Ideal Solution (TOPSIS), in which the weights of each variable are optimized in order to capture the direction of the relationship between the two sets of efficiency measures. Findings: Although the authors find that the collective efficiency of the educational units analyzed did not change during the period of study, the analysis reveals that government indicators of performance do not exhibit a strong relationship to the ideal solution efficiency measures used in this study. Originality/value: This study extends the educational institution efficiency literature by examining Brazil’s FIEST, which consists of 40 educational units throughout the country that spans several levels of education, from upper high school vocational courses to higher degrees.

Keywords: Educational institution efficiency, Education economics, TOPSIS, Technical school performance, Data envelopment analysis.

ArtigosA scenario-based experimental study of buyer supplier relationship commitment in the context of a psychological contract breach: Implications for supply chain management

International Journal of Production Economics, v. 249. Abstract: Mutually beneficial long-term relationships between supply chain partners are the key to supply chain performance. However, these relationships may sometimes be undermined due to unforeseen events (e.g., supply chain disruptions). This study aims to originally examine the buyer-supplier relationship (BSR) commitment if the buyer’s psychological contract is breached by the supplier. The study originally examines the effect of supplier-induced disruptions over a new product development project on the buyer’s relationship commitment. It also evaluates the impact of the repair strategies employed by the supplier on the commitment to repair. These relationships are examined on two levels. First is the case where the buyer’s focal manager has a cooperative or confrontational relationship with the supplier’s focal manager. Second is the case where a prior (i.e., pre-disruption) relationship between the buyer and the supplier was collaborative or adversarial. We studied the research model using experimental methods on a sample of 204 supply chain managers from Pakistani industries. The results of this study show that the initial interpersonal and interorganizational relationships affected the response of the buyer when its psychological contract with the supplier was breached. The repair strategy of financial compensation is shown to have a considerable influence on repairing the commitment level of the buyer.

Keywords: Perceived contract breach, Supply chain management, Buyer-supplier relationship, Commitment, Social exchange theory.

ArtigosInformation entropy, continuous improvement, and US energy performance: a novel stochastic-entropic analysis for ideal solutions (SEA-IS)

Annals of Operations Research, v. 313, pp. 289–318. Abstract: To address the gap in energy performance studies regarding the role of information entropy in feedback processes between input and output slacks, the paper develops a novel Stochastic-Entropic Analysis for Ideal Solutions (SEA-IS) model. The non-linear stochastic optimization model is then applied to assess the potential information gains that may arise from energy slacks minimization given the different optimal reduction quantiles in US states. The model relies on Beta distributed priors to model the odds-ratio of learning feedback and takes advantages of numerous strengths present in DEA and TOPSIS approaches for performance management. Machine learning methods are also employed to predict information gains in terms of contextual variables. We find that California is the only U.S. state that has indicate strong mutual information feedback and continuous improvements in efficiency. The results indicate there is ample scope for harnessing the power of information gains in improving energy efficiency, particularly in 37 U.S. states, which indicates scope for a public–private partnership to achieve this goal.

Keywords: US energy, Performance, State-level, Stochastic-entropic approach, Information gains, Slack management, Feedback.

ArtigosUnveiling endogeneity and temporal dependence in energy prices and demand in Iberian countries: a stochastic hidden Markov model approach

Annals of Operations Research, v. 313, pp. 191–229. Abstract: In this paper, we analyze the temporal dependence in energy prices and demand using daily data of Portugal and Spain over the period 2007–2017. The methodology used is based on a stochastic Hidden Markov Model and the results indicate first that all significant relationships between energy prices and demands were found to be positive; second, spot prices are only time dependent on future prices and spot energy, while future energy is solely time dependent on spot energy behavior; third, future prices are not only autocorrelated but also time-dependent with spot energy and future energy demands level; and finally, spot energy is autocorrelated and time-dependent with future prices and future energy. Policy implications of the results obtained are presented at the end of the article.

ArtigosNatura Goes Shopping: The Case of an Emerging Market Multinational

Revista de Administração Contemporânea, v. 26, n. 6. Abstract: This teaching case explores a unique international trajectory of an emerging market multinational in the cosmetics, fragrances, and toiletries industry. Natura & Co presents two very different internationalization strategies in two distinct moments:  the first decisions seem to follow the gradual and incremental model described as the Uppsala model; later on, the company moves toward a more daring approach, explained by the springboard perspective, as it enters a series of large international acquisitions.  The case is originally designed for disciplines of international business and international strategy at the graduate level and explores the above-mentioned theories, internationalization motives, and entry modes.

Keywords: Teaching case, Internationalization strategy, EMNE, Uppsala model, Springboard perspective.

ArtigosUncertainty and tourism in Africa

Tourism Economics, v. 28, n. 4, pp. 964–978. Abstract: Tourism growth is on the rise in Africa, and yet limited empirical evidence exists that explores the factors that drive this important contributor of economic growth on the continent. Previous literature focuses mainly on developed countries. This study weighs in on the recent debate on African tourism by providing evidence on the role that economic uncertainties have on tourist arrivals. Using panel data from 1996 to 2017, we find that economic uncertainties reduce tourist arrivals in Africa in comparison to other global regions, such as Europe. Further disaggregation by African regions reveals that economic uncertainties in West and North African regions drive these adverse results. These regions have been the hardest hit by political instability and social unrest during the period under review, which may have acted as a deterrent to tourists.

Keywords: Africa, Panel data, Tourism, Uncertainty.

ArtigosEntrepreneurial environment attractiveness: a cross-country longitudinal cluster analysis

Competitiveness Review, v. 32, n. 4, pp. 546-564. Abstract: Purpose: The purpose of this work is to explore what determines a country’s entrepreneurial environment attractiveness, by understanding how countries compare regarding their business environment and entrepreneurial opportunities and whether such aspects have changed over time. Design/methodology/approach: Through a longitudinal country-level cluster analysis of business environments (years 2001 and 2016), this study captures changes in classification of both emerging and developed market economies throughout an attractiveness spectrum, from least to most attractive environments. Findings: Interesting findings involve the difference in trajectories of emerging economies, such as India compared to the stagnation of Brazil, Argentina and South Korea in the 15-year period. The paper seeks to contribute to the debate on the attractiveness of the entrepreneurial environment beyond the simple notion of most and least economically developed countries by providing a framework for dynamic cross-country analysis of entrepreneurial environmental attractiveness that can be further explored, tested and expanded. Research limitations/implications: Main limitations relate to the non-exhaustive sample of countries and variables. Contributions are both academic and managerial: helping to fill important research gaps in international entrepreneurship, namely, environmental conditions, cross-country comparisons (Coombs et al., 2009) and the understanding of elements of the investment climate (Stern, 2002); and assisting managers, entrepreneurs and policymakers understand what defines a country’s entrepreneurial environment attractiveness to better evaluate potential locations for investment. Originality/value: The originality of the paper lies in using cluster analysis in a longitudinal study of country attractiveness, as well as in advancing the debate of country attractiveness, by adding a temporal dimension (from factors that are less structural to more conjunctural) and a comparative dimension in a new cross-country comparison framework of analysis.

Keywords: Longitudinal study, Cluster analysis, Business environment, Country competitiveness, Country attractiveness, Cross-country analysis.

ArtigosEcological efficiency assessment under the construction of low-carbon city: a perspective of green technology innovation

Journal of Environmental Planning and Management, v. 65, n. 9, pp. 1727-1752. Abstract: This paper develops a novel hybrid Trigonometric Envelopment Analysis for Ideal Solutions (TEA-IS) model to assess the ecological efficiency of 248 Chinese cities for a 14-year period and employs a difference-in-difference approach to reveal the mechanism of the impact of low-carbon pilot city policies on ecological efficiency from the perspective of green technology innovation. This TEA-IS approach not only combines the advantageous features that exist in each individual model, but also allows an analysis of ecological efficiency in terms of the synergistic effects that may exist among correlated positive and negative criteria. Machine learning methods are also employed to predict high-low performance and synergistic Chinese cities in terms of the socio-economic and demographic context. Results indicate that ecological efficiency is generally low in Chinese cities. The low-carbon pilot city policy does help to improve ecological efficiency, which results from the mechanism of green technology innovation.

Keywords: Ecological efficiency, TEA-IS, Low-carbon city, Green technology innovation.

ArtigosChallenges and uncertainties in Rio’s hospitality industry: the case of Astor Hotels

Tourism and Hospitality Management, v. 28, n. 1, pp. 233-253. Abstract: International mega sporting events such as the Olympic Games have been responsible for promoting transformations over the years in the cities they pass through whether through developing economic sectors such as tourism, hospitality, and services or through transforming their urban spaces. The case of Rio de Janeiro in 2016 was emblematic above all for the city’s hotel sector, which during the years preparing for the Games saw its offer in the number of beds increase by 76% in a period of just 5 years, which generated a new competitiveness dynamic for the region. The case puts the reader in the role of Federico Gonzales, manager of Astor Mediterranean Rio, a new hotel that opened near the Olympic Park at the end of 2015 and is currently experiencing serious financial difficulties given the drop in demand aggravated by the economic crisis and by the effects of the pandemic. The case is indicated for undergraduate and graduate students from the hospitality, tourism, and strategy courses interested in discussing themes and concepts related to the area of strategic transformation of hotel industry, management strategic decision making, and mega events.

ArtigosForeign direct investment and Olympic Games: A systematic literature review

Journal of Convention & Event Tourism, v. 23, n. 2, pp. 95-128. Abstract: Motivated by the urban transformations observed in cities that hosted the Olympic Games in the recent years, this article aims to map and analyze the scientific publications that linked mega sporting events to foreign direct investment in different times and realities in order to understand the positive and negative impact that such a conjuncture causes on the business environment with different challenges and opportunities for the companies located in these regions. We believe that although the Olympic Games were chosen to represent this study, its results and propositions can be applied to other mega event contexts occurring in either developed or emerging locations. To this purpose, a systematic review of the literature was made based on the combined search of the terms “Foreign Direct Investment” and “Olympic Games,” which gathered a final sample of 170 publications from 17 of the most relevant databases in the world. It was verified that although few studies have dealt with this issue as a central theme of discussion, they have been gaining relevance mainly since the Beijing Olympics in 2008. Thus, after mapping what has been discussed in the area, the main themes explored, theoretical perspectives, research gaps have been identified in order to contribute to a better understanding of the phenomenon. At the end, a theoretical framework is presented with the objective to guide future studies in the area.

Keywords: Foreign direct investment, Institutional theory, Olympic Games, Emerging countries, Mega events.

ArtigosThe Tokyo 2020 Olympic Games: impacts of COVID-19 and digital transformation

Cadernos EBAPE.BR, v. 20, n. 2, pp. 318-332. Abstract: The Olympic Games have been responsible for moving billions of dollars in direct and indirect investments during their winter and summer editions in the host cities, thus leaving tangible and intangible legacies that, if well used, can promote significant changes in the daily lives of societies. For the first time in the modern era of the Olympic Games, at the beginning of 2020, this cycle had to be postponed due to the COVID-19 pandemic that had killed more than 4 million people worldwide by July 2021. The teaching case puts the reader in the role of Hiroto Nakami, then President of the Tokyo 2020 Organizing Committee, to solve operational barriers and make it possible to create a successful digital Olympic Games model. It will be necessary to evaluate the financial and technological limitations in order to assess the impacts and legacies from these actions for the event and the local business environment. The case is suitable for multidisciplinary undergraduate and graduate students interested in discussing themes and concepts related to the area of strategic planning, crisis management, mega-events, and digital transformation.

Benchmarking: An International Journal, v. 29, n. 5, pp. 1513-1545. Abstract Purpose: The purpose of this paper is to assess the efficiency determinants of mergers and acquisitions (M&A) in the context of Latin American airlines based on business-related variables commonly found in the literature. The idea is to identify preferable potential airline matches in light of fleet mix, ownership structure and geographical proximity. Design/methodology/approach: In order to achieve the objective, all possible combinations of M&A pairs are considered in the analysis, which is developed in a two-stage approach. First, the M&A Data Envelopment Analysis model efficiency and returns-to-scale estimates are computed. Then, robust regression and multinomial logistic regression are respectively used to discriminate these estimates in terms of such business-related variables. Findings: The results reveal that these different contextual variables significantly impact virtual efficiency and returns-to-scale levels. Private ownership, passenger focus and a better match between aircraft size and demand for flights appear to be key drivers for merged airline efficiency. Research limitations/implications: The study makes theoretical contributions, though limited to analyzing Latin American airlines only. The use of bootstrapped robust/multinominal logistic regression, compared to the methods adopted by previous literature studies, generates more accurate and robust results related to the efficiency drivers due to its special feature and ability to allow the discrimination of increasing, decreasing, and constant returns to scale in light of a given set of contextual variables. Practical implications: This study examines the pure effect of the merging activity on efficiency gains. Not only private ownership but also a hybrid public–private ownership has a positive influence on virtual efficiency, suggesting an important governmental role in promoting M&A in the airline industry. Originality/value: The authors present an original take on the issue of airline mergers by exploring what are the major drivers possibly involved in efficiency gains of potentially merged (virtual) airlines. The authors identify preferable potential airline matches where efficiency gains would be positive in light of business-related variables such as fleet mix, ownership structure and geographical proximity. The analysis also includes an assessment of the impact of contextual variables such as cargo type, ownership structure and geographical proximity in relation to the strategic fit of mergers considering the resulting efficiency and returns-to-scale scores of virtually merged airlines. To the authors’ knowledge, no previous research has addressed these issues in Latin American airlines. Further research directions for this industry are also discussed.

ArtigosHost city transportation issues: conceptualization, scale development, and validation

Sport, Business and Management, v. 11, n. 3, pp. 321-339. Abstract: Purpose: Planning and managing the transportation services for Olympic host cities is a complex task. This paper contributes to the event management literature by presenting empirical evidence of the public transportation issues using a case study of a local community-focused Olympic host city. Key factors underpinning transportation issues outcomes are identified. Design/methodology/approach: The Rio 2016 Olympic city was selected as a case study. To develop a scale of public transportation issues, four stages of scale development were conducted: a construct definition and content domain; item generation and expert review; a quantitative study for the purification of the scale; and a quantitative study to validation of the scale. Data were collected among local citizens who lived in the Olympic host city (n = 513). Findings: The construct of public transportation issues was assigned to five main categories: planning, infrastructures, information, insecurity and urban mobility. The scale shows internal consistency, reliability, construct validity and nomological validity. Transport issues perceived of Olympic host city tend to increase the negative social impact perceived among local citizens. Originality/value: This study contributes to the harmful impacts discussion of hosting sport mega-events and introduces the transportation issues that the Local Organizing Committee (LOC) needs to know when hosting the Olympic Games. The scale application for the future Olympic host countries is discussed.

Keywords: Public transportation issues, Transport legacy, Host cities, Rio 2016, Rio Olympic city.

ArtigosDoes the Olympic legacy perceived in the host city influence the resident support after the games?

International Journal of Sport Policy and Politics, v. 13, n. 3, pp. 393-408. Abstract: This study aims to explore and describe the structural relationships among (a) perceptions of city transport legacy, (b) trust in the government, and (c) resident support towards the Olympic Games. A field study was conducted in Rio de Janeiro 4-years post-Games, and data were collected from residents who lived in the Olympic city through a self-administered questionnaire (n = 452). A confirmatory factor analysis (CFA) analysed the psychometric properties of the constructs, and a subsequent structural equation model (SEM) examined the relationships between the constructs. The direct-effects model and the partially mediated model were tested based on the mediating role of transport structural legacy. Results indicated that Rio’s resident support for the mega-event is essentially influenced by their trust in the local government, while their perceptions of Olympics legacy alone may be a negative predictor of support behaviour. The findings confirmed the predictive power of residents’ trust in government on achieving high event support, suggesting its inclusion in future models. Implications focus on effective synergies of political and social engaging to enhance the public support level in the host city.

Keywords: Resident Support, Governmental Trust, Transport Legacy, Olympics, Rio de Janeiro.

ArtigosCredit information and financial development

International Journal of Finance & Economics, v. 27, n. 2, pp. 2182-2193. Abstract: This article evaluates the possible effects of the presence and coverage of credit bureaus over financial development. In order to achieve this objective, this study uses International Monetary Fund aside from World Bank database and standards, more specifically financial development and credit bureau coverage variables. Results indicate a positive impact of credit bureaus over financial development. The potential channel associated with this effect might be related to the information produced by credit bureaus, which implies a reduction in asymmetric information in credit markets, thus, leading to a lower level of risk associated with borrowers and, consequently, reducing the risks faced by banks. With lower levels of uncertainty and risk, banks tend to lend more, improving financial development, which could suggest the adoption of a policy to create or stimulate credit bureaus coverage.

Keywords: Credit information, Developing countries, Financial development.

ArtigosFailure factors in healthcare quality improvement programmes: reviewing two decades of the scientific field

International Journal of Quality and Service Sciences, v. 14, n. 2, pp. 291-310. Abstract: Purpose: Quality improvement is imperative for healthcare organisations. Despite the importance of the topic, many efforts have been wasted on failed improvement programs. Various studies have tried to identify the failure factors in improvement programs, but the divergences in the results hamper this research field’s evolution. This study reviews scientific activity from 2000 to 2019 on failure factors in Healthcare Quality Improvement Programs (HCQIP) to help academics and managers understand the field’s evolution better. This research intends to answer four questions on failure factors in HCQIP: Who are the most active authors in this field? Which journals have been used as diffusion channels?; What are the themes addressed the most in this field?; and What are the themes considered to be emerging? Design/methodology/approach: The authors conducted a bibliometric-based literature review on a sample of 5,137 articles, and 104 studies were included in this review, covering a longitudinal analysis in two periods (P1: 2000–2010 and P2: 2011–2019). Performance analysis, citation, co-citation, co-words analysis and network mapping identified the authors in this scientific field, the journals, the number of articles, along with the current and emerging themes that reveal the latent structure of the factors associated with failures in HCQIP. Findings: The number of articles in P2 (83 studies) is almost four times higher than in P1 (21 studies). The results reveal a dynamic field attracting more authors since 2013, expanding from 5 to 42 journals that publish on the topic. Furthermore, research has evolved from comprehensive manufacturing programs to more theory-based and contextualised health care. In this sense, the recent literature (P2) suggests that failure factors related to quality improvement programs can be minimised if these initiatives align with the human centrality paradigm. Practical implications: Analysing the evolution of failure factors in HCQIP helps redesign research and management for better quality health outcomes. Knowledge of the scientific community trajectory over nearly 20 years enables better planning from the patient’s perspective and contributes to reducing failures in quality programs. Originality/value: This study contributes to developing the field of failure factors in HCQIP by providing researchers and managers with an evolutionary, systematic and pioneering view of the theme.

ArtigosFinancial performance drivers in BRICS healthcare companies: Locally estimated scatterplot smoothing partial utility functions

Journal of Multi-Criteria Decision Analysis, v. 29, n. 1/2, pp. 173-185. Abstract: The Healthcare sector is increasing in importance and relative size in BRICS countries (Brazil, Russia, India, China, South Africa). Despite BRICS relevance, the financial performance of their healthcare companies has been scarcely studied. This research fills this literature gap not only by focusing on the impacts of such diverse business environments on the financial performance of healthcare providers but also by proposing a novel approach to estimate an overall financial performance index based on weighted additive utility functions given a set of financial performance criteria. Precisely, bootstrapped Singular Value Decomposition is the cornerstone for identifying an orthogonal base of rotated financial performance criteria, upon which partial utility functions (PUFs) are estimated using locally estimated scatterplot smoothing (LOESS) polynomial regression. A compromise weighting scheme between singular values and quadratic programming results for minimal covariance and joint entropy matrices of residuals was used for summing up the PUFs. Results indicate that the values of financial performance range between 0.7 and 0.85. We further find that current assets, level of debt and liability, the company’s Tobin Q are related to the financial performance. Besides, business freedom, government integrity, tax burden, monetary freedom and government spending are also the determinants of financial performance.

Keywords: Financial health index, LOESS estimation, Multiple criteria analysis, SVD, Utility functions.

ArtigosDo contingent convertible bonds reduce systemic risk?

Journal of International Financial Markets, Institutions and Money, v. 78, 101554. Abstract: In this paper, we implement an empirical analysis to discuss the impact of CoCo bond issuance on the systemic risk using three systemic risk measures for banks: SRISKSES and ΔCoVaR. Our results show that issuing CoCo bonds the first time decreases systemic risk as a positive response to a future crisis. However, the second issuance increases the systemic risk, possibly by demonstrating a higher risk of financial distress or capital needs. Moreover, we provide evidence that smaller banks, banks with larger loans ratios to their total assets, and banks with unstable sources of funding are more benefited by CoCo issuance. We also perform robustness checks for all the findings and discuss policy implications.

Keywords: Systemic risk, CoCo bonds, Crisis.

ArtigosPsychic income benefits of the Rio 2016 Olympic Games: comparison of host community pre- and post-Games perceptions

Journal of Sport & Tourism, v. 26, n. 1, pp. 21-41. Abstract: This study aims to examine psychic income perceptions of the Rio 2016 Olympic Games before and after the event. Data were collected among Rio residents by using a pre-Games (n = 350) and post-Games design (n = 403). The cross-sectional data were assessed over time and the results gathered through a confirmatory factor analysis (CFA) for assessing the psychometric properties of the 7-factor scale. Subsequently, MANOVA and a series of ANOVA tests were performed to analyse the differences in perceptions before and after the Games. The CFA results showed factorial stability of the psychic income model in both periods, while the mean comparisons revealed significant differences in all psychic dimensions in the short term. Results indicated that resident perceptions of psychic income tend to increase from pre- to post-event. This study evidences the psychological effects of hosting a sport mega-event, leading to a better comprehension of how local communities perceive the event’s impact within a short time frame.

Keywords: Psychic income, Socio-psychological benefits, Olympic Games, Host communities, Rio de Janeiro.

ArtigosPerceived quality of hospital services from the perspective of doctors and patients: An integrative model

Latin American Business Review, v. 23, n. 1, pp. 1-20. Abstract: The objective of the article is to develop a conceptual model that jointly examines the perception of doctors and patients regarding the quality of services provided by public and private hospitals in Rio de Janeiro. We interviewed 61 doctors and 40 inpatients; the results indicated that the gap in the perceived quality of health services, according to the perception of doctors and patients, is a function of failures in the institution’s infrastructure, in the relationship between doctors and patients, and in the access to services. Such gaps may impair the outcome of care delivered to patients.

Keywords: Doctor, Patient, Perception, Quality gaps, Quality of health services.

ArtigosSocial networks uses and motivations: Proposition and test of an integrative model

Latin American Business Review, v. 23, n. 1, pp. 21-47. Abstract: This study (1) identifies motivations for using social networks (SNs) and (2) tests an integrative model. A systematic literature review was conducted followed by mixed-method research. Technology, social, and individual domains of SNs motivators were identified. The qualitative stage of the research supported the selection of the variables to be tested, and the survey tested these motivations with a sample of 468 respondents. As a result, a new model highlighting the main motivations for using online social networks emerged. Competition and Collective Narrative are new constructs that explain social media use, together with Escapism, Information, Identity, and Socialization.

ArtigosCross-Border Health Care Services as Inward Internationalization

Internext, v. 16, n. 3, pp. 306–323.Abstract Purpose: The research aimed at investigating the pre-conditions and the decision-making process by which physician-entrepreneurs adopt CBHCS as part of their business. Method: The study uses the case method of investigation. Main results: Results showed that, in the cases studied, international experience and international networking are relevant characteristics of the physician-entrepreneur, besides country reputation, cultural and language similarities, and physician reputation. In addition, the decision processes of the physician-entrepreneurs in these organizations are based on an effectual logic. The offer of cross-border health care services was a combination of given means and contingencies, which helped the entrepreneurs to discover, or to create, the opportunity, and then develop it. Relevance/originality: The research combines the literatures on effectuation and inward internationalization to study the decision-making process of adopting CBHCS by medical clinics. Theoretical contributions: The study contributes to the literature by identifying certain pre-conditions and providing an in-depth analysis of the use of effectual logic by physician-entrepreneurs in their decision-making process of adopting CBHCS.

ArtigosFemale entrepreneurship in emerging markets: challenges of running a business in turbulent contexts and times

International Journal of Gender and Entrepreneurship, v. 14, n. 1, pp. 95-116. Abstract Purpose: The present study seeks to investigate female entrepreneurship in turbulent times (COVID-19) and contexts (emerging markets). Design/methodology/approach: An in-depth, multiple-firm (five SMEs), cross-country (2 countries – Brazil and Tunisia), cross-region (Latin America and the MENA region) case study based on a mixed embeddedness perspective. Findings: The study highlights how challenges and uncertainties are managed, what inspires female entrepreneurs and what frightens them. We capture these entrepreneurs’ insecurities, self-doubts and creative survival strategies. Our findings reinforce the need for self-efficacy and resilience, as well as the importance of a support network and the ability to “reboot” whenever needed. Despite persistent patriarchal norms and cultures, the women surveyed did not see themselves as female entrepreneurs but as successful entrepreneurs, akin to their male counterparts. Research limitations/implications: Academically, the study contributes to the fields of entrepreneurship, female entrepreneurship and crisis management with empirical evidence in new contexts (LATAM and MENA regions) and times (collected during a crisis). The results also contribute in a practical way to female entrepreneurs, policy makers and global agencies. Originality/value: The study’s originality arises from a qualitative cross-country comparison of findings from internationally minded companies from under-researched developing countries and regions at an especially interesting and turbulent time: the pandemic of 2020.

Keywords: Female entrepreneurship, Cross-country comparisons, Emerging markets, Entrepreneurship, Turbulence, Crisis, COVID-19.

ArtigosDifferent roots, intertwined branches: linking International Business and Economic Geography through the Uppsala Model and Global Production Network

International Marketing Review, v. 39, n. 1, pp. 105-119. Abstract Purpose: The aim of this study is to propose a link between international business (IB) and economic geography, which are two streams of thought that have developed without one acknowledging the other. We use the Uppsala model and the Global Production Network as pillars to sustain this link. We expect that this research triggers a collaboration with allied social sciences in important debates surrounding the business-societal interface. Design/methodology/approach: We selected papers produced by Johanson and Vahlne to understand the development of the Uppsala model over 40 years. The same was done with the Global Production Network, where we scrutinized the work of Henderson, Coe, Dicken, Hess and Yeung – scholars from the Manchester School of Geography – in the last twenty years. Based on Humphrey et al. (2019), we applied an inductive and inferential approach to uncover similarities and differences between the Uppsala model and Global Production Network. Findings: The Uppsala model reinforces the strategic role of network position in the internationalization process, while the Global Production Network aims to explain how the governance of global firms scattered world-wide affects the development and upgrading opportunities of the various regions and firms involved. Despite these clear differences, the geographical nature of IB and shared similarities accounting the network as a channel to foster and provide access to important resources and practices regarding management, coordination and governance of dispersed parts of multinational enterprises give room to using these two theories as pillars to link IB and economic geography. Originality/value: While attempts to link IB and economic geography are not new, none of these studies have focused on the Uppsala model and Global Production Network as pillars to create a link. We foresee an intense cross collaboration and an even possible renaissance of IB and economic geography to target the ever-changing business environment and its impact on social and economic development.

Keywords: Uppsala model, Global production network, International business, Economic geography, Governance, Upgrade, Social and economic development.

ArtigosDoes ownership structure affect firm performance? Evidence of Indian bank efficiency before and after the Global Financial Crisis

International Transactions in Operational Research, v. 29, n. 3, pp. 1842-1867. Abstract: This paper investigates the relationship between bank ownership and efficiency before and after the 2008–2009 Global Financial Crisis. Using a sample of 58 Indian commercial banks from 2005 to 2017, we examine the interconnection between these factors in a dynamic data envelopment analysis (DEA) framework. We use an innovative modeling strategy based on a two-stage dynamic DEA framework. The first stage employs the Dynamic Slack-Based Measure model to measure bank efficiency, explicitly considering the effects of desirable and undesirable carry-overs between consecutive periods. In a second stage, we perform a regression of the efficiency scores on bank ownership types and several other contextual factors, while also accounting for the presence of endogenous relationships between the variables involved. Our results show that foreign banks outperform their domestic competitors, with bank size and profitability being the main drivers. We also find that while foreign and state-owned banks were more efficient than their rivals during the Global Financial Crisis, private banks recovered quickly, reaching the efficiency standards of state-owned banks by 2017. The latter faced a prolonged decrease in efficiency, gradually losing their initial advantage over their private domestic counterparts. Our results are robust to alternative regression specifications, especially those aimed at addressing potential endogeneity issues. The applied methodology and the findings of our research should be of interest to scholars, bank managers, and policymakers. The latter, in particular, should be concerned about the medium-term effects of reforms that unevenly affect banks with different ownership structures, especially in terms of bank resilience to aggregate shocks.

Keywords: Banks, DEA, DSBM, Efficiency, Global financial crisis, Ownership.

ArtigosSupplier selection in the oil & gas industry: A comprehensive approach for Multi-Criteria Decision Analysis

Socio-Economic Planning Sciences, v. 79. Abstract: The focus of this paper is on selecting suppliers in the Oil and Gas (O&G) industry by developing a comprehensive approach for Multi-Criteria Decision Analysis (MCDA) based on alternative methods capable of assessing different aspects of supplier selection uncertainty in terms of utility functions and criteria related to efficiency. The O&G industry has a key role in the public sector of various countries such as Iran with its revenues being of prime importance to develop infrastructure facilities such as for healthcare, education, and transportation. This comprehensive approach walks through various stages for selecting Critical Success Factors (CSFs), ranking suppliers, and for setting partial weighting alternatives. While CSFs are selected using a traditional Delphi approach, the partial supplier rankings are defined based on Complex Proportional Assessment (COPRAS) utility functions together with criteria weights derived from Step-wise Weight Assessment Ratio Analysis (SWARA) for each CSF. As it concerns information reliability of utility and efficiency functions of both methods obtained via expert preferences or perceptions, Z-numbers are used to address the intrinsic fuzziness level inherent to each analytical stage. Iran’s economy depends on revenues from oil and other related production, which means that by earning more income from this industry, most of its economic indicators such as GDP and employment rate should increase significantly, thus leading to economic growth. Various countries put plans in place related to production for increasing their social economics. One of these plans is focused on suppliers since they have a high impact on providing essential items such as equipment, HR, and transportation, so by choosing the best suppliers in all fields, costs will decrease and consequently revenue will increase. This research points out how to rank O&G industry suppliers using MCDA methods in an uncertain environment. An example based on actual data from an Iranian O&G company is provided to show the applicability of the approach proposed. Results suggest that the complexity of O&G operations on selecting suppliers can be adequately handled by information reliability techniques applied to traditional economic concepts such as utility- and efficiency-related factors, particularly in business environments characterized by a trade embargo.

Keywords: Supplier selection, COPRAS, Delphi method, SWARA, Z-Numbers, Oil & gas industry, Social economic planning.

ArtigosSegmentation of current and potential investors in retirement plans to retain and capture customers

Brazilian Business Review, v. 19, n. 1, pp. 19–38. Abstract: The goal of this research was to fill the gap represented by the lack of studies that apply Behavioral Finance concepts in the segmentation of investors in retirement savings plans. Based on a bibliographic review, and the study of multiple cases, there was revealed relevant aspects of the supplemental retirement market in Brazil, this article proposes a new set of demographic and psychographic variables that were more effective in previous research in the segmentation of financial services clients. It innovates by incorporating variables from Psychology and Behavioral Finance, especially the “rationality” variable which has a remarkable ability to synthesize vulnerabilities to a wide universe of heuristics and biases when applied to investors. In addition, significant behavioral barriers were identified for the expansion of the retirement market, such as a low level of maturity of current market practices in Brazil and the need to use Behavioral Finance instruments in this confrontation.

ArtigosIntegrating Corporate Social Innovations and cross-collaboration: An empirical study

Journal of Business Research, v. 139, pp. 794-803. Abstract: This article presents a new way of implementing corporate social innovations (CSI) through cross-collaboration, by analyzing the integration of these two constructs, which are usually studied separately, offering an actual perspective to address persisting social problems while reaching business results. Our findings are based on case studies conducted with key executives and consultants from social enterprises, nonprofits, multinational corporations, large enterprises, and B-Corps from Brazil, USA, Canada, Iceland, and Sweden to compare different regions with different social problems using Mirvis and Googins (2017) framework to analyze the integration of CSI and cross-collaboration in corporate strategies. Results allow us to propose a new spectrum between social and commercial business models and their relationships with governments and civil society, demonstrating that the action of all stakeholders is already taking place in different ways according to the realities of each region, promoting impactful results that are beneficial for business and society.

Keywords: Cross-sector collaboration, Corporate Social Innovation, Social Innovation, Social Impact.

ArtigosFounder’s added value in a startup valuation. Could an expert be worth an extra penny?

Revista Ciências Administrativas, v. 27, n. 3. Abstract: The Brazilian Startup market has been growing fast recently, but the assessment of a startup company is still considered a black box by many authors and investors in the market. The main reason for the difficulty of evaluating a startup is the lack of a universal methodology applicable to this type of company. In this article, the authors tested an alternative way to evaluate a company using key variables from the founder’s experience. Approximately 30 Brazilian VC funds and the profile of 130 founders with public data were analyzed, and we found significance in the founder’s senior management experience before the funding stage. The result is still basic to consider a new assessment approach for startups, but the main conclusion of this article is relevant: the experience of senior management has a significant and consistent impact on the assessment of a startup in Brazil.

Keywords: Venture capital; Startup valuation; Founder’s track record; Experience frontier.

ArtigosDeterminantes de alavancagem: uma reanálise dos países do G7

Revista de Gestão dos Países de Língua Portuguesa, v. 19, n. 1, pp. 1–13. Resumo: Nos aprimoramos a teoria de Rajan e Zingales (1995) por meio da análise de dados de um período mais recente e de técnicas estatísticas mais robustas. Comprovamos que o modelo teórico proposto por Rajan e Zingales continua atual, mesmo levando em conta correções para autocorrelações seriais e controlando pela alavancagem inicial. Porém, o nível de tangibilidade mostrou-se não ser significante, o que é atribuído a mudança da estrutura das firmas dos países desenvolvidos. Assim, este estudo contribui para uma modificação dos determinantes de alavancagem nos países componentes do G7.

ArtigosGovernance modes in supply chains and financial performance at buyer, supplier and dyadic levels: the positive impact of power balance

Benchmarking: An International Journal, v. 29, n. 1, pp. 255-284.Abstract Purpose: This study analyzes whether power in the supply chain, based on governance modes and network centrality, explain financial performance at different levels of analysis: buyers, suppliers and dyads. Design/methodology/approach: The study employs a dual macro-micro lens based on global value chain (i.e. market, modular, relational and captive governance modes) and social network analysis (network centrality) to assess the impact of power (im)balance onto financial performance. Different from previous research, this study adopts information reliability techniques – such as information entropy – to differentiate the weights of distinct financial performance metrics in terms of the maximal entropy principle. This principle states that the probability distribution that best represents the current state of knowledge given prior data is the one with largest entropy. These weights are used in TOPSIS analysis. Findings: Results offer insightful reflections to SCM research. We show that buyers outperform suppliers due to power asymmetry. We ground our findings both analyzing across governance modes and comparing network centrality. We show that market and modular governances (where power balance prevails) outperform relational and captive modes at the dyadic level – thus inferring that in the long run these governance modes may lead to financially healthier supply chains. Originality/value: This study advances SCM research by exploring the impact of governance modes and network centrality on performance at both firm and dyadic levels while employing an innovative combination of secondary data and robust set of techniques including TOPSIS, WASPAS and information entropy.

Keywords: Power, Global value chain, Governance mode, Network centrality, Dyadic financial performance, TOPSIS, Information entropy.

ArtigosQuality assurance systems: enemies or allies of innovation in higher education institutions?

Quality Assurance in Education, v. 30, n. 1, pp. 1-18. Abstract Purpose: This study aims to examine the extant literature to analyze the relationship between quality assurance (QA) and innovation in the higher education context. Design/methodology/approach: This study selected 63 articles through a systematic literature review in Scopus and Web of Science databases and performed a descriptive and thematic synthesis-analysis on the sample. Findings: The research identifies several perspectives discussed on QA systems covering experiences, criticisms and practice implications. The literature review shows there is no clear consensus on whether innovation in higher education institutions (HEIs) is fostered or hindered by QA processes. However, it seems that the likelihood of innovativeness and positive QA outcomes are directly linked to how these processes are managed in universities. Research limitations/implications: This review highlights the university management concerns that emerge with QA issues as it is not yet clear to what extent innovation is actually promoted in scenarios where QA is applied. Hence, this literature review could be considered comprehensive but not exhaustive. Further studies are recommended to improve the understanding of how HEIs can both innovate and ensure quality at the same time. Originality/value: The paper contributes to the existing body of knowledge by advancing the opportunities and challenges that HEIs face due to QA system features.

Keywords: Higher education, Quality assurance, Innovation, Organizational management, Systematic literature review.

ArtigosMAC: Uma proposta para metas atuariais consistentes em fundos de pensão

Revista de Administração Contemporânea, v. 26, n. 3. Resumo Objetivo: viabilizar a proposição de um novo método, a Meta Atuarial Consistente (MAC), que evita, ajustando-as, metas atuariais incompatíveis nos fundos de pensão, após investigar e comprovar, na pesquisa, que a meta dissocia-se da regra geral dos normativos vigentes, que adere essa meta à expectativa de rentabilidade dos investimentos do plano de previdência. Metodologia: foi elaborada uma amostra contendo dados de 22 planos BD, onde aplicou-se a MAC depois de os métodos de dados em painel identificarem os elementos que influenciam a definição da meta atuarial ocorrida no conselho deliberativo dos respectivos fundos de pensão. Resultados: a utilização da MAC, adequando as metas atuariais de 2018 a partir dos vieses sistemáticos ocorridos nas metas anteriores, possibilitou um efeito positivo que se desdobra em estimativas mais fidedignas para as provisões matemáticas dos planos, ao mesmo tempo que identificou elementos que influenciam na determinação do valor da meta anual, provocando sua não aderência à regra geral da legislação. Conclusões: a adoção da MAC pela Previc aperfeiçoaria o regramento e forneceria subsídios para melhor adequar os níveis de contribuição praticados nos planos, tornando mais fidedignos seus níveis de solvência, o que beneficiaria o desenvolvimento do mercado de seguros e de previdência.

ArtigosArquitetura de escolhas na tomada de decisão de turistas no contexto da pandemia de Covid-19

Revista Brasileira de Pesquisa em Turismo, v. 16, pp. e-2465. Resumo: Na medida em que mais informações se tornaram disponíveis a respeito da pandemia de Covid-19 no mundo, algumas propostas com objetivo de conter sua dispersão tiveram origem no campo das ciências comportamentais. Devido à necessidade de mudança de comportamentos individuais inerente ao tipo de transmissão do novo coronavírus, acredita-se que o arcabouço teórico sobre arquitetura de escolhas e nudges se apresenta como um importante instrumento para orientar os debates. Neste sentido, o presente artigo visa identificar e categorizar as medidas adotadas por empresas turísticas para sua reabertura no contexto da pandemia de Covid-19. Para isto é realizado um estudo de casos múltiplos com um hotel, um aeroporto e um atrativo turístico internacional, que tiveram que realizar intervenções em suas estruturas físicas e processuais para voltarem a operar. A partir das análises constatou-se que a maior parte dos nudges contou com técnicas de simplificação da informação, visibilidade de ações externas, redução de esforço físico e lembretes. Técnicas de normas sociais e de ampliação da visibilidade do comportamento foram pouco exploradas pelos empreendimentos analisados neste estudo. Por fim, o trabalho documenta uma estratégia de intervenção holística no comportamento dos turistas, que combina nudges a incentivos financeiros e formas mais duras de paternalismo.

ArtigosFinancial contagion in internet lending platforms: Who pays the price?

Finance Research Letters, v. 45. Abstract: By using data from a natural experiment, the 2015 Ezubao scandal in China, we show that as a consequence of negative news about a P2P financial platform, all players operating in a different platform (borrowers, lenders, and the platform itself) are worse-off due to information contagion. Moreover, we present evidence that high-income individuals and those that contracted loans for investment purposes are disproportionately affected by contagion from negative news.

ArtigosUnveiling endogeneity between competition and efficiency in Chinese banks: a two-stage network DEA and regression analysis

Annals of Operations Research v. 306, pp.131–171. Abstract: Although there is a growing number of research articles investigating the performance in the banking industry, research on Chinese banking efficiency is rather focused on discussing rankings to the detriment of unveiling its productive structure in light of banking competition. This issue is of utmost importance considering the relevant transformations in the Chinese economy over the last decades. This is a development of a two-stage network production process (production and intermediation approaches in banking, respectively) to evaluate the efficiency level of Chinese commercial banks. In the second stage regression analysis, an integrated Multi-Layer Perceptron/Hidden Markov model is used for the first time to unveil endogeneity among banking competition, contextual variables, and efficiency levels of the production and intermediation approaches in banking. The competitive condition in the Chinese banking industry is measured by Panar–Rosse H-statistic and Lerner index under the Ordinary Least Square regression. Findings reveal that productive efficiency appears to be positively impacted by competition and market power. Second, credit risk analysis in older local banks, which focus the province level, would possibly be the fact that jeopardizes the productive efficiency levels of the entire banking industry in China. Thirdly, it is found that a perfect banking competition structure at the province level and a reduced market power of local banks are drivers of a sound banking system. Finally, our findings suggest that concentration of credit in a few banks leads to an increase in bank productivity.

ArtigosMemes as shortcut to consumer culture: A ethodological approach to covert collective ideologies

Revista de Administração Contemporânea, v. 26, n. 4. Abstract: Objective: the paper proposes the methodological use of memes as a shortcut to explore consumer culture. Memes as cultural texts can reveal collective circulating ideologies that may not be accessed through regular interviews. Context:   memes   are   cultural   texts   that   convey   easy-to-understand   messages, gaining strength within social networks. Cultural texts playfully present the social context and beliefs of societies. We analyzed circulating memes during the COVID-19 pandemic about elderly consumers in Brazil to outline a methodological protocol. Method: we analyzed memes adopting the discourse model to conduct qualitative research of memes as a shortcut to cultural discourses.  We collected memes during March and May 2020 using social media networks. They were classified following thematic analysis. Result: the proposal is a methodological procedure for analyzing memes as a cultural text. The process starts with the outline of a data collection protocol, followed by data analysis guidelines, illustrated by the context of elderly consumers. Conclusion: the analysis of memes as cultural texts contributed to understanding of consumer behavior through current cultural content, revealing contrasting ideologies that emerge from consumers as covert value-systems, circulating alongside  institutional  mass-mediated ideologies.

Keywords:   Memes, Cultural   text, Consumer   ideology, Culture   and   consumption, Qualitative research.

dObra[s] – Revista da Associação Brasileira de Estudos de Pesquisas em Moda, n. 31, p. 237–261. Resmo: O objetivo deste estudo de abordagem interpretativa foi analisar postagens, em redes sociais, de grupos religiosos femininos em busca de negociações simbólicas que, a partir da moda, profanam o sagrado e sacralizam o profano. O percurso metodológico ancorou-se na captação e na análise das imagens de looks construídos, das legendas que as acompanham e dos textos e comentários compartilhados juntamente com as fotos. Dez contas de Instagram –de mulheres caracterizadas como influenciadoras digitais e identificáveis como pertencentes à igreja Assembleia de Deus – foram acompanhadas e analisadas. Os resultados encontrados discutem sobre o uso, por essas mulheres, do capital da moda para borrar os limites das regras religiosas, fazendo negociações simbólicas entre o campo mundano e o religioso, o que nos permitiu relacionar esses achados com a sociedade da transparência de Han.

Latin American Business Review, v. 22, n. 4, pp. 309-321. Abstract: Despite the abundance and steady growth of Latin American research on supply chain sustainability, studies are often limited to mimicking the Global North discourse without addressing the special needs of the region. In this Editorial, we evaluate the current Latin American landscape on the topic by introducing four papers selected for this Special Issue, while reflecting on the need to decolonize scholarship on supply chain sustainability by re-bounding its notions of time and space within the codes of Latin American epistemologies. We contend that the region has the potential to develop its own research framework and still contribute to the global debate.

ArtigosThe impacts of cryptocurrencies in the performance of Brazilian stocks’ portfolios

Economics Bulletin, v. 41, n. 3. Abstract: This study analyses the impact of including cryptocurrencies in Brazilian stocks’ portfolios performances from September 2014 to April 2020. The comparisons were made between stocks’ only portfolios against portfolios that allowed stocks and cryptocurrencies. Three portfolios served as benchmarks: the naïve but relevant equally weighted portfolio, the tangency and the MVP portfolios built from the Markowitz mean-variance theory. Performances were compared through out-of-sample returns, volatilities, Sharpe, Sortino and Omega ratios. Our results indicate positive statistically significant return and risk-adjusted improvements after the inclusion of cryptocurrencies, although also increasing the volatility. The equally weighted portfolios with cryptocurrencies often outperformed the tangency and minimum variance models, which only exhibited better results when more data was used as input to the models. Moreover, the portfolios that included cryptocurrencies consistently outperformed the IBrX-100 in the period studied. The results of this study are important for investors and fund managers, especially because cryptocurrencies are yet not considered by most of them.

ArtigosIslamic banking efficiency literature (2000–2020): a bibliometric analysis and research front mapping

International Journal of Islamic and Middle Eastern Finance and Management, v. 14, n. 5, pp. 1043-1060. Abstract Purpose: This paper aims to present a citation-based bibliometric review of Islamic banking efficiency literature from 2000 until August 2020 for analyzing the content of the literature and mapping future research directions. Design/methodology/approach: Using bibliometric citation analysis, this study reviews and examines a total of 278 documents from Web of Science (WoS) indexed sources coupled with content analysis. Findings: The results identified that the growth of Islamic banking efficiency literature has begun to rise since 2008 with an annual growth rate of 12.5% while identifying the most influential aspects of Islamic banking efficiency literature in terms of topics, papers, authors and keywords. The outcomes of science mapping (i.e. co-citation network, bibliometric coupling and co-authorship network) reveal that there are three underlying research streams in Islamic banking efficiency literature: growth of Islamic banking efficiency literature, stability and genuineness of Islamic banking operations and the methods in Islamic banking efficiency literature. Originality/value: To the best of the knowledge, this is the first bibliometric review paper on Islamic banking efficiency literature. It successfully unveils the scientific mapping of published WoS documents with a future research agenda also proposed based on the review outcomes. These findings can be used in efficiency-related initiatives by managers or regulators for managing Islamic bank operations worldwide.

ArtigosCritical success factors for competitive advantage in Iranian pharmaceutical companies: A comprehensive MCDM approach

Mathematical Problems in Engineering, v. 2021. Abstract: The unprecedented COVID-19 outbreak strengthened the critical manifestation of the rapid development vs. survival for pharmaceutical companies, deploying strategic conduct worldwide. This study therefore explores the endogenous relationship among pharmaceutical companies’ manufacturing strategy and their performance indicators within the ambit of creating a long-lasting competitive advantage in turbulent times. Very often, it is not possible to launch a cause-effect relationship between performance and their drivers. To achieve this end, multiple-criteria decision-making (MCDM) techniques are employed in a hybrid fashion in this study. The notion has simultaneously ranked critical success factors (CSFs) in the manufacturing strategy and performance indicators in the limelight of managerial perceptions, while controlling the inherent bias concerning the causality direction in the ambit of these two entrenched concepts. A case study on the Iranian pharmaceutical companies is piloted to demonstrate this hybrid-fashion multifarious approach. Overall, the results revealed the most pertinent CSFs that reached superior-performance echelons in the Islamic Republic of Iran.

ArtigosAnálise de performance e de alocação de fundos de pensão de servidores públicos

Revista Brasileira de Risco e Seguro, v. 15, n. 27, pp. 21-46. Resumo: Este estudo analisou, de 2015 a 2019, a performance e a alocação de quatro fundos de previdência complementar fechada de servidores públicos federais (Funpresp-Exe e Funpresp-Jud) e dos estados do Rio de Janeiro (RJPrev) e Espírito Santo (PREVES). O desempenho de todos os fundos pelo índice Sharpe mostrou-se superior ao calculado para os índices do mercado de ações brasileiras. Isso se deu por conta da baixa volatilidade apresentada pelos fundos, com retornos ligeiramente superiores ao CDI e inferiores ao Ibovespa. Foram investigadas as carteiras por Análise Estática e Dinâmica de Estilo, observando-se oito fatores de risco: renda fixa prefixada, pós-fixada e híbrida (inflação), investimentos imobiliários, ações bolsa Brasil, ações exterior, câmbio e dívida externa. Os dois últimos fatores não apresentaram significância para nenhum fundo e saltou aos olhos a altíssima exposição à renda fixa, principalmente dos tipos pós-fixada (de menor volatilidade e menor retorno esperado) e híbrida, em menor grau. Ficou evidente a baixíssima exposição à renda variável (isto é, a risco) por parte de todos os fundos analisados, o que pode ser um indicativo do setor. Se considerarmos a característica fundamental do longo prazo nesses fundos, tal baixa exposição sugere falta de diversificação e ineficiência, sendo, portanto, não benéfico aos participantes. Além disso, em alguns períodos, o modelo apresentou baixos coeficientes de determinação, que podem advir da parte da carteira com ativos marcados na curva do papel, como na renda fixa híbrida, a exemplo das NTN-B (IPCA+) com duration longa: essa prática reduz artificialmente a volatilidade do fundo, inflando o índice Sharpe.

ArtigosFinding targets in non-radial FDH models: A hybrid technique based on STEM and extended ratio based approach

Applied Sciences, v. 11, n. 22. Abstract: Performance evaluation using interactive methods and extended ratio-based approaches can be very important for some organizations. Free disposal hull models can be created if there is no concern for convexity, and using non-radial DEA models can simultaneously create more logical and practical situations for finding DMU targets. In this paper, a new hybrid technique based on the additive slack based method and enhanced Russel measure in variable return to scale technology has been proposed. The proposed technique can find decision making unit targets in non-radial free disposal hull models using the step method. Furthermore, the extended ratio-based approach in the proposed technique has been applied to find DMU targets of related non-radial free disposal hull models without solving any mathematical programming models. Finally, targets of Fars province pharmaceutical distributing companies were found by applying the proposed hybrid technique.

Keywords: Data envelopment analysis (DEA), Additive slack based method, Non-radial free disposal hull (FDH), Step method (STEM), Ratio-based approach (RBA).

ArtigosInventory pooling decisions under demand scenarios in times of COVID-19

Computers & Industrial Engineering, v. 161. Abstract: Governments have been challenged to provide timely medical care to face the COVID-19 pandemic. The aim of this research is to propose a novel inventory pooling model to help determine order sizes and safety inventories in local hospital warehouses. The current study attempts to portray the availability of pharmaceutical items in public hospitals facing COVID-19 challenges. Different from previous studies, this research builds upon the consecrated theory of inventory pooling, extending it to pandemic circumstances where the intractability of kurtosis and skewness in inventory models are critical issues for making sure that medicines have high availability at a low cost. These effects on the total cost of inventory are explored and compared to a supply system with no consolidation. A continuous-review model is assumed with allocation rules for centralization and regular transshipment given different skewness and kurtosis structures for the demand, describing them by the copula method. This method models a multivariate demand considering that the marginal distributions of the demand can be specified by the Generalized Additive Model for Location, Scale and Shape, which offers advantages to model demands considering virtually any marginal statistical distribution. Numerical simulations and an illustrative example show that distributions of demands with more negative skewness and high kurtosis favor to a greater extent obtaining lower total costs with regular supply transshipment systems. Our study points out important considerations for supply chain decision makers when having demands with skewness and kurtosis patterns.

Keywords: Resource allocation, Inventories, Hospital, Models, Statistical.

ArtigosSustainability drivers in road transportation system Evidence from China

Science of The Total Environment, v. 798. Abstract: This research explores the sustainability drivers of the Chinese road transportation system in terms of its cargo and environmental productivity levels. A novel Fuzzy Double-Frontier Network Data Envelopment Analysis (FDFNDEA) model is proposed to investigate the relationship between desirable (freight and passenger turnovers) and undesirable (CO2 and NOx emission levels) outputs against the respective power consumed in each one of the 29 Chinese provinces (municipalities and autonomous regions) between 1985 and 2017. The power consumption emerges spatially and temporally as a consequence of the evolution of the road system’s productive resources (employees, highway length, number of vehicles, and fuel consumed) at the province level over the course of time. Shannon’s entropy is used as the cornerstone to quantify input and output vagueness of this evolution in terms of triangular fuzzy numbers (TFN), thus allowing the building of alternative optimistic and pessimistic double efficiency frontiers. Respective Malmquist Productivity Indexes (MPI) for overall and each stage productivity are regressed against contextual variables related to demography, economic activity, competitor infrastructure, and highway quality using bootstrapped Cauchy regressions. Results confirm the disruptive evolution of the Chinese road transport system over the course of the years and different expansion strategies at the regions. The energy and environmental efficiency of the Chinese road transportation system is affected by these contextual variables.

Keywords: Sustainability, MPI, Double frontier, Fuzzy NDEA, Shannon’s entropy, Chinese roads.

ArtigosRevisiting the accounting fraud components: A bottom-up approach using the Twitter platform

Sage Open, v. 11, n. 4, pp. 72–83. Abstract: Despite the relevant economic and reputational impact of fraud, research in this field remains fragmented. This study aims to create a new framework for accounting fraud, defining its main components from the social media user’s perspective. In terms of research technique, an online data collection using social media platform was used retrieving, through the phyton web crawler procedure, 43,655 tweets containing the phrase “accounting fraud” from July 2006 to December 2019. Individual words were identified and treated within the selected tweets, excluding stop words and, finally, using a sparsity index. The proposed methodology, which overcomes traditional survey inherent bias efficiently, contributes to bridging the divide between academia and society. We find that Twitter users shape the Accounting Fraud Hexagon, composed by (i) The Object and the Tool (of misrepresentation), being the Financials, (ii) The (Guilty) Fraudster, (iii) The Defrauded, (iv) Materiality, (v) The Consequences, and (vi) the Watchdog. Our research has several implications. Our research identifies additional “angles” of vision to the traditional fraud triangle-diamond-pentagon theories compared with the existing top-down conceptual frameworks. Also, since it uses a bottom-up instead of a top-down approach, the study allows a more comprehensive definition of accounting fraud, thus contributing to the debate for a common language in this field. We expect to encourage more research using social media as a tool to test the literature built on in vitro theories empirically.

ArtigosUsing data envelopment analysis and the bootstrap method to evaluate organ transplantation efficiency in Brazil

Health Care Management Science, v. 24, n. 3, pp. 569–581. Abstract: Brazil has the most extensive public program for organ transplantation in the world, and the Brazilian National Health System (SUS) provides full coverage of all costs involved in organ donation, transplants, and post-transplant. Despite the relevance of the subject and the shortage of organs for transplants, transplantation process efficiency assessments are still uncommon in Brazil and abroad. This study aims to evaluate the efficiency of the Brazilian states and the Federal District in transforming potential organ donors into actual donations. We applied data envelopment analysis (DEA) in conjunction with the bootstrap technique, using organ transplantation data from 2018. The bootstrap methods applied (bootstrap technique, the bootstrap-biased scores of efficiency, and the bootstrap bias-corrected scores of efficiency) allow to obtain a confidence interval for DEA scores and provide greater robustness to studies based on DEA methodology. The bootstrap bias-corrected model indicates that there is significant room for improvement in terms of converting potential donors into actual donors. The mean corrected score is 0.55, signalizing that altogether the Brazilian states could maximize in 45% the number of transplanted organs without necessarily increasing the pool of potential donors. The study provides insights into the Brazilian processes of organ donation and transplantation, helping to identify locations in need of resource allocation improvements. Given the scarcity of studies with a joint application of DEA and bootstrap techniques in this crucial health activity, we also intend to methodologically contribute to this type of benchmark analysis, emphasizing the importance of considering measurement errors, randomness, and bias at DEA models.

Keywords: Bootstrapping, Brazil, Data envelopment analysis, Efficiency analysis, Organ donation-transplantation process.

ArtigosRedução da desigualdade tributária entre empresas via novo pilar previdenciário

Revista Eletrônica do Departamento de Ciências Contábeis, v. 8, n. 1, pp. 52-78.  Resumo: No Brasil, somente as empresas tributadas pelo lucro real podem deduzir, da base de cálculo do IRPJ e CSLL, contribuições patronais efetuadas aos planos de previdência privada de seus colaboradores. Esse benefício fiscal pode provocar uma anomalia ao afetar balanços contábeis e impactar a competitividade entre empresas, quando se observam outros tipos de tributação impedidas de efetuarem essa dedução. Nesta pesquisa ampliamos esse benefício às empresas tributadas pelo lucro presumido para apurar o impacto da renúncia fiscal. A partir de dados de arrecadação e de folhas salariais, construímos e aplicamos um simulador atuarial para encontrar alíquotas de contribuição que fossem suficientes para gerar aposentadorias que cobrissem 65% do último salário do trabalhador. Em seguida, utilizamos os montantes de contribuição patronal e estimamos a renúncia fiscal máxima possível, que correspondeu a 3,7% da arrecadação anual dos tributos das empresas brasileiras. Esse patamar mostrou-se reduzido para o Governo, mas relevante para as empresas beneficiadas ao agregar às políticas de RH um benefício pós-emprego direto aos empregados. Com isso, potencializa-se o aumento da produtividade do trabalhador e colabora-se para a retenção de mão-de-obra qualificada, fatores que melhoram a concorrência, além de tornar o sistema tributário mais equilibrado. Consideramos que o preenchimento dessa lacuna na legislação, pouco explorada em artigos acadêmicos, beneficiará trabalhadores, empresas e o país. A extensão do benefício estimula mais pessoas a pouparem para suas aposentadorias, fomenta uma melhor educação financeira na sociedade e incentiva a poupança de longo prazo, altamente benéfica para o país.

ArtigosOptimal portfolio strategies in the presence of regimes in asset returns

Journal of Banking & Finance, v. 123. Abstract: This paper analyzes optimal portfolio and consumption strategies in a regime-switching economy with unobservable states and predictability of risky asset returns. We develop approximate analytical solutions to the unconstrained dynamic problem. The approximation is shown to be fast and accurate in a four-regime setting with an allocation to four assets compared to the numerical solution developed in Guidolin and Timmermann (2007). The computation time of the approximate solution is shown to be practically independent of the number of assets when no predictors are present and only marginally affected by the number of predictors. While the portfolio policy strongly depends on the current state of the economy, the consumption-to-wealth ratio is roughly state-independent. Predictability considerably changes the optimal portfolios. Hedging demands are negligible with regimes and no predictability, but are important with predictability. On the other hand, the consumption-to-wealth ratio is not very impacted by the predictor. We provide an out-of-sample statistical assessment of the returns provided by a multi-regime strategy with respect to a single-regime and to a 1/N strategy.

Keywords: Dynamic asset allocation, Stochastic differential utility, Consumption and portfolio optimal strategies, Regime switching economy, Predictability, Large and small caps, Size effects.

ArtigosTaxa interna de retorno dos regimes de previdência social no Brasil: Uma análise das reformas de 1988 a 2018

Administração Pública e Gestão Social, v. 13, n. 1. Resumo: Este estudo, através da estimativa de taxas internas de retorno e de taxas de reposição de segurados hipotéticos, verifica o impacto no custo previdenciário individual e na convergência entre regimes previdenciários geral e próprio das principais reformas desde a Constituição de 1988 até a proposta de emenda constitucional, PEC n° 287/2016, bem como a emenda aglutinativa global à proposta apresentada pelo relator no dia 07 de fevereiro de 2018. Foram analisadas as particularidades de cada uma dessas reformas, a trajetória das taxas e os subsídios cruzados existentes para, assim, sugerir as principais alterações a serem feitas para que se alcance um sistema previdenciário mais sustentável e regimes convergentes. As taxas de retorno mais elevadas para benefícios baixos apontam que o sistema possui características de progressividade. Apesar dos resultados indicarem alguma convergência no período e queda nos custos, as reformas anteriores se mostraram insuficientes para sanar o desequilíbrio. Concluiu-se, assim, pela necessidade de uma nova reforma, que pode ter como norte a proposta de 2016, porém mais profunda e abrangente.

BASE –Revista de Administração e Contabilidade da Unisinos, v. 18, n. 4, pp. 611-634. Resumo: Este trabalho analisa o histórico da estrutura a termo de juros reais, obtida através do modelo de Svenssone disponibilizada pela Associação Brasileira das Entidades do Mercado Financeiro e de Capitais (ANBIMA).  Tal curva é de grande valia no mercado e possui diversas aplicações, tais como a realização de teste de adequação de passivos para a indústria seguradora, estimativa da inflação esperada (IPCA) ou mesmo a marcação de títulos a mercado. A partir de uma análise histórica, considerando dados diários de fechamento de 21/09/2009 a 28/06/2019, identificamos algumas   discrepâncias   que   precisam   ser   reconhecidas e discutidas.   Há   uma sensibilidade exagerada do modelo a períodos de instabilidade política e erros não desprezíveis na estimativa de taxas de curto prazo, bem como uma volatilidade exagerada nas taxas de longo prazo.  Tais observações sugerem cautela aos entes do mercado que utilizam a curva. Existem variações abruptas nos parâmetros, bem como taxas de curtíssimo prazo negativas muitas vezes, algo totalmente fora da realidade brasileira.  Foram observadas também taxas com volatilidade acima do previsto em teoria, trazendo incertezas para os participantes do mercado.

ArtigosPolypharmacy and the coproduction of the experience between physicians and patients

Teoria e Prática em Administração, v. 11. Abstract: Purpose: To identify how physicians can help polypharmacy patients deal with their disease condition by focusing on the non-clinical factors of care processes. Therefore, this study aims to answer the following specific questions: (1)  What  are  the  causes  of  polypharmacy?  (2)  How do patients experience the consequences of polypharmacy? (3) How can the service coproduction concept help physicians manage and reduce polypharmacy? Methodology: We applied a qualitative exploratory study. Data were collected by in-depth interviews, and the material was analyzed considering three coproduction dimensions – knowledge, skills, and motivation. Main results: This research found that several non-clinical factors may cause polypharmacy and trigger problematic phenomena. Accordingly, several initiatives that add value for patients who are in polypharmacy were suggested. Academic contributions:  This research increases the knowledge about the non-clinical polypharmacy factors and possible initiatives to mitigate this condition. It is also essential because there are few studies focused on this subject in developing countries like Brazil. Practical contributions: This study proposed several interventions that physicians can use to manage polypharmacy.

Keywords: Healthcare, Polypharmacy, Non-clinical factors, Value for patients, Coproduction.

ArtigosTax systems as (non-) participatory mechanisms the cases of Brazil and the United States cases of Brazil and the United States

Agenda Política, v. 9, n. 2, pp. 155-184. Abstract: The paper investigates the Brazilian and American income tax system to analyze how tax expenditures may act as a participatory mechanism in public budgeting. The literature on charitable deductions and tax expenditures suggests that tax systems may have a ballot nature, nonetheless few studies have addressed the issue. Thus, the paper aims to fill this theoretical gap by exploring how citizens may express their preferences to the government via tax deductions and by proposing a framework to compare the implications of each institutional design. Data showed that, yet differently, both tax systems allow a certain degree of participation and result in a substantial modification in how governments execute public policies and spend public resources. The comparison of the cases indicated that the same mechanism can be more or less participatory and that tax expenditures should be analyzed not only in terms of their financial results but also concerning their influence on democracy.

Keywords: Income tax, Tax expenditures, Participatory budgeting, Citizen participation, Public budgeting, Democracy.

ArtigosInhospitable accessibility and blurred liability: Institutional voids in an emerging economy preventing supply network transparency

BAR – Brazilian Administration Review, v. 18, n. 2, pp. e200078. Abstract: Research on supply network transparency is incipient and focused on how focal firms can improve monitoring of supplier misbehavior. This narrow focus has restricted advancements in the topic. Our research, firstly, shifts the focus from supplier to focal firm misbehavior, and secondly, focuses on Brazil as an exemplar of an emerging economy. We explore how institutional voids influence supply network transparency. We focus on how voids in regulation, labor market, and contracting systems provide fruitful land for buyer misconduct and undermine supply network transparency. We review legislation in five developed countries to contrast with legislation in Brazil and we synthesize six years of Brazilian law suits regarding outsourcing issues in the apparel sector. This study exposes that voids can ease pressures allowing firms to navigate ‘below the radar’ and sustain poor working conditions along the supply network. Within this context, society has limited information availability and accessibility – what we label inhospitable accessibility (due to the regulatory void), as well as limited proportionality between real risks in the supply network and traceability of those risks back to the buying firm – what we label blurred liability (due to voids in labor market and contracting systems), thus preventing supply network transparency.

Keywords: Supply network transparency, Institutional void, Institutional isomorphism.

ArtigosBiopharmaceutical supply Chain challenges in developing countries: an exploratory analysis

Supply Chain Forum: An International Journal, v. 22, n. 4, pp. 294-309. Abstract: Biological medicines have grown in importance for treating some chronic diseases better than regular chemical medication. However, they demand specialised services in the biopharmaceutical supply chain (BSC) compared to conventional drugs. This paper aims to understand the BSC’s main challenges in Brazil and the critical factors for its development. We conducted exploratory qualitative research, interviewing ten senior professionals. Findings showed that the main logistics challenges are the end-to-end temperature control in the supply chain and a collaborative relationship within the supply network. This research also highlights some social, political, and economic challenges faced by developing countries like Brazil. Those findings contribute to extending the literature on BSC and help managers understand and prepare for the new challenges of the BSC, especially in emerging economies. Future qualitative studies can deeply investigate each of the aspects raised in this exploratory research, especially regarding the impact of political, economic, social, and environmental elements on the BSC.

ArtigosImproving information reliability of non-radial value efficiency analysis: An additive slacks based measure approach

European Journal of Operational Research, v. 298, n. 2, pp. 967-978. Abstract: The value efficiency approach is one possible way of incorporating information preferences into performance analysis of Decision-Making Units (DMUs). In this paper, we propose a novel geometric interpretation of value efficiency while plugging it into radial and non-radial DEA (Data Envelopment Analysis) models under the assumption of variable returns to scale. In addition, this novel geometric interpretation of value efficiency is extended to Additive Slacks-Based Measure (ASBM) modeling. This is achieved by linearization of non-radial DEA models using multi-objective programming. Performance of such proposed approaches in terms of reliability and discriminatory power are compared through a case study involving Finish bank branches. Research implications are then derived and conclusions are drawn.

Keywords: Data envelopment analysis, Value efficiency, Additive slacks-based measure, Multiple objective linear programming, Non-radial.

ArtigosFrom campfire to coliseum: motivations for using social networks

Qualitative Market Research, v. 24, n. 5, pp. 610-631. Abstract Purpose: Through a literature review, a gap has been identified regarding the role of competition as a driver of social network (SN) usage. This study aims to design to address this gap, seeking motivators for SN usage based on how SN consumption may be related to users’ experience of competition. Therefore, the purpose of this study is to investigate the influence of competition in social media usage. Design/methodology/approach: The authors used an exploratory qualitative approach, conducting a set of focus groups with young social media users. Data was analyzed with software. Findings: Two new drivers for SN use are proposed, namely, competition and collective narrative. Research limitations/implications: This is an exploratory study, and it does not seek to generalize results or quantify causal relationships among variables. Practical implications: This paper offers SN managers a deeper understanding of key growth drivers for these media. Social implications: This research can help society understand and debate the impacts of SNs on users’ lives, providing insights into drivers of excessive usage. Originality/value: This paper proposes the following two SN usage drivers yet to be described in the literature: competition and collective narrative.

Keywords: Competition, Gamification, Flow theory, Social network use, Social media.

ArtigosThe mega events paradox analyzing the behavior of the hospitality industry in the city of Rio de Janeiro during and after the Olympics

Revista Brasileira de Pesquisa em Turismo (RBTUR), v. 16. Abstract: Considering the urban transformations and the development of the hotel sector in the City of Rio de Janeiro driven by the 2016 Olympic Games, this study aims to understand how the hotel industry behaves in terms of organic growth and investments during periods of mega international events. To this end, a qualitative case study research was carried out that included 7 different hotel brands whose results were coded and categorized resulting in a theoretical-conceptual framework responsible for identifying some competitive pressures on traditional hospitality, including 6 different challenges: (1) political institutional insecurity, (2) perceptions of the media, (3) public security, (4) other national and foreign locations, (5) new videoconference technologies, and (6) Online Travel Agencies. It was found that the exponential growth in the number of beds in the city in the years leading up to the 2016 Olympics generated several complications for the industry at that time. The logic of this expansion is discussed throughout the paper during different phases and the aim is to help fill a gap left by empirical research in the area, which has little explored the logic behind the option of investing during Olympic Cycles.

Keywords: Mega Events, Olympic Games, Tourism and Hospitality, Institutional Theory, Rio de Janeiro.

BAR−Brazilian Administration Review, v. 18, n. spe. One  panel  in  the  International  Conference  of  Information  Systems  (ICIS),  held  in  December 2016 in Dublin, attracted attention that surpassed the hundreds of seats of the auditorium and forced the security to close the doors when the stairs became completely occupied. The audience, eager to join the debate on the research perspectives on the topic of blockchain in the information systems (IS) field, represented one of the first academic manifestations of the great expectations placed on this emergent topic in this research community. One year later, the organizers of this panel (Avital, Beck, King, Rossi, & Teigland, 2016) were the editors of what was probably the first special issue on blockchain in a relevant IS journal (Beck, Avital, Rossi, & Thatcher, 2017). Although these events indicate milestones for the IS field, the blockchain started to shake the world almost a decade before.

ArtigosTransportation Sustainability, Macroeconomics, and Endogeneity in China: A Hybrid Neural-Markowitz-Variable Reduction Approach

Technological Forecasting and Social Change, v. 170. Abstract: This paper analyzes the sustainability of the transportation sector in China by investigating feedbacks or endogenous effects among energy consumption, transportation, and major macroeconomic variables and their consequent CO2 emission levels related to fiscal policy, monetary policy, inflationary pressure, and economic activity. A novel combination of Alternative Variable Reduction Techniques, a Markowitz Portfolio Selection Model, and Neural Networks is applied on monthly data from January 1999 to December 2017. The main idea is to develop a hybrid approach to unveil endogeneity in China’s transportation footprint, which is mostly impacted by energy consumption and CO2 emission levels of different transportation modes and major macro-economic factors while simultaneously exploring the epistemic uncertainty that surrounds this issue as captured by Information Entropy, Variance Inflation Factor, and Covariance matrix. It can be concluded that road transportation has played a dominant role in decreasing the entire sustainability level, which is mainly driven by trade and fixed-asset investment as well as monetary and fiscal policy, while consumer expectations and cornerstone economic prices have shown limited impact on the transportation footprint. Railways and waterways help mitigate the harmful impacts of increased economic activity and expansionist monetary and fiscal policy on the transportation footprint.

ArtigosGovernance and networks for health co-benefits of climate change mitigation: Lessons from two Indian cities

Environment International, v. 97, pp. 146–154.  Abstract: Health has been the main driver for many urban environmental interventions, particularly in cases of significant health problems linked to poor urban environmental conditions. This paper examines empirically the links between climate change mitigation and health in urban areas, when health is the main driver for improvements. The paper aims to understand how systems of urban governance can enable or prevent the creation of health outcomes via continuous improvements in the environmental conditions in a city. The research draws on cases from two Indian cities where initiatives were undertaken in different sectors: Surat (waste) and Delhi (transportation). Using the literature on network effectiveness as an analytical framework, the paper compares the cases to identify the possible ways to strengthen the governance and policy making process in the urban system so that each intervention can intentionally realize multiple impacts for both local health and climate change mitigation in the long term as well as factors that may pose a threat to long-term progress and revert back to the previous situation after initial achievements.

ArtigosCharacters with disabilities in Brazilian telenovelas: Almost invisible consumers is included

Global Journal of Management and Business (GJMBR), v. 14, n. 4. Abstract: Although important vehicles of culture and of society’s values and perspectives, cultural texts represent little explored possibilities in the research focusing on the behavior of consumers with disabilities.  In Brazil, telenovelas, or evening TV drama series, present as suitable cultural texts for such studies, in view of the importance of this type of programming as material that both crosses class lines and has national penetration. The objective of this study was to discuss how the consumption decisions and practices of people with disabilities are presented in Brazilian telenovelas.  To achieve the objective, 22 Brazilian telenovela scenes showing characters with disabilities in situations of consumption were reviewed. The results of the study call attention to the need for companies, public institutions and society in general to review how they address these almost invisible consumers, who are often overlooked as potential customers and excluded from public policy actions.

Global Journal of Management and Business, v. 13, n. 3. Abstract: Purpose: This study intends to investigate if the Basic Fairness Model (Rutte and Messick 1995) is supported across cultures in Brazil, Germany and the United States. Design/methodology/approach: To test the model across cultures, structured focus groups were conducted in Germany, Brazil and the United States. Findings: The Focus groups generally supported the basic fairness model, although with a few modifications and additions. Culture affects understandings of appropriate behavior. Research limitations/implications: To a great extent, the difference in the Focus group participants’ responses reflected the realities of their different environments. There are also no doubt differences in how different businesses operate. Such differences can lead to perceptual differences.

Resumo: O caso de ensino Unimed Leste Fluminense apresenta uma situação decisória que deve ser enfrentada por Dilson Reis, diretor de mercado da organização. O caso descreve a trajetória da empresa desde a sua fundação e apresenta o momento em que o diretor, pressionado pela concorrência e pela grande regulação do setor, questiona como aumentar a sua base de clientes. No momento da decisão, o setor apresenta forte intensificação na competição, sendo a maior disputa pelos grandes clientes empresariais, tanto entre os operadores de planos de saúde quanto entre os corretores que vendiam esses planos. A preferência por clientes empresariais decorria principalmente das restrições impostas pela regulamentação da Agência Nacional de Saúde Suplementar, aplicáveis aos clientes pessoa física. A estrutura de canais da Unimed Leste Fluminense não era bem definida, já que seus canais de venda competiam pelo atendimento de clientes pessoa física e jurídica, não havendo uma gestão coordenada de lojas, vendedores próprios, concessionárias e corretores. Nesse contexto, os possíveis conflitos de canal desgastavam a operadora, que fazia de tudo para conquistar o cliente, mas tinha pouco poder de influência sobre os parceiros de canais. O caso proporciona uma oportunidade para a discussão sobre a necessidade de alinhamento de estrutura dos canais de marketing aos objetivos de crescimento da firma. Possibilita ainda uma reflexão sobre a natureza dos conflitos multicanal e as ações requeridas para o gerenciamento de canais. Trata-se de um caso real, elaborado a partir de entrevistas em profundidade com Benito Petraglia, Dilson Reis e Jair da Costa Jr., respectivamente diretor administrativo, diretor de mercado e gerente de mercado da Unimed Leste Fluminense. Para facilitar o processo de envolvimento dos alunos, o dilema do caso foi apresentado na perspectiva de Dilson Reis. Informações secundárias foram utilizadas para triangulação dos dados e para complementação da descrição do caso. Utilizaram-se ainda dados secundários para descrever o setor de saúde suplementar, mais especificamente o segmento de planos de saúde, de forma a oferecer ao aluno a possibilidade de contextualização do caso. Recomenda-se a discussão do caso nas disciplinas de canais de distribuição ou canais de marketing em cursos de pós-graduação lato ou stricto sensu, especialmente para programas cujo método supõe a aprendizagem centrada no participante. Espera-se que o aluno assuma papel ativo na preparação individual do caso, discussão em grupo e na sessão plenária.

ArtigosFatores formadores da percepção do desempenho em feiras B2C na perspectiva do expositor

Gestão Contemporânea, Porto Alegre, n. 13, pp. 123-148. Resumo: O objetivo deste estudo foi investigar quais fatores influenciam a percepção do desempenho em feiras ao consumidor (B2C) no setor de vestuário brasileiro, na perspectiva dos expositores. Em virtude da escassa existência de estudos acadêmicos sobre feiras ao consumidor, o referencial teórico sobre os fatores que afetam a percepção de desempenho das feiras de negócios (B2B) foi utilizado para o estabelecimento de seis proposições, relacionando a percepção de desempenho com os objetivos de vendas; construção de marca; construção de relacionamento; obtenção de informação; motivação e lançamento de novos produtos. Dado o caráter exploratório, o método usado foi o estudo de casos múltiplos. As evidências empíricas permitiram suportar cinco das seis proposições originais e ainda a sugestão de uma proposição empírica, de que as Feiras ao Consumidor podem servir como um canal outlet/off-price para vender os estoques excedentes de produtos da marca de vestuário, que não foram escoados nos canais convencionais.

Palavras-chave: Feiras ao consumidor. Desempenho em feiras. Setor de vestuário.

ArtigosThe world financial crisis and the international financing of Brazilian companies

BAR – Brazilian Administration Review, v. 10, n. 1, pp. 18-39. Abstract: The world financial crisis initiated in 2008 may have affected the international financing mix of firms in Brazil and their determinants, given its aftereffects. Financial crisis are recurrent events with varying degrees of severity. Many public Brazilian firms use international financing in their capital structure mix and it is relevant to understand their behavior during international crises. Thus, our goal was to investigate the foreign financing mixes of Brazilian listed companies before (2004) and during the 2008 world financial crisis by means of descriptive and probit regression analyses of their components and determinants at the end of these years. Brazilian companies usage of Eurobonds fluctuates with the value of the real (R$) and is still small considering the size of Brazil’s economy. Short-term financing and bank loans, domestic and foreign, decreased in 2008 and were replaced by domestic and international bonds and American Depository Receipts (ADRs). Firms with foreign shareholders more often resorted to foreign capital markets and their presence became a more important determinant in 2008, while the other determinants did not change. Firms that employ international debt tend to use all other sources of financing more often. International bank loans may be the first step to reduce international financing constraints.

Keywords: Financial crisis, International corporate financing, Capital structure, Brazilian listed firms.

ArtigosProdução científica brasileira em Finanças no período 2000-2010

Revista de Administração de Empresas, v. 53, n. 1, pp. 46-55. Resumo: Este artigo faz uma avaliação bibliográfica quantitativa e qualitativa dos artigos de Finanças publicados em 11 periódicos científicos nacionais, por meio de levantamentos sobre coautorias, áreas temáticas e uma análise da produtividade dos autores. A coautoria tornou-se uma característica predominante. As áreas temáticas mais comuns, finanças corporativas e gestão de investimentos, refletem a abundância de dados de empresas com ações em bolsa, negligenciando as demais. A produtividade é concentrada em poucos indivíduos no Sudeste e mais baixa do que o previsto pela teoria bibliométrica. A grande maioria dos autores publicou apenas um artigo e apenas 5% publicaram cinco ou mais. A maior parte dos artigos internacionais dos autores prolíficos consta de periódicos de baixo impacto. A pouca inovação teórica e metodológica dificulta publicações internacionais de impacto. A avaliação da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes) parece estimular parcerias, mas sugeriram-se novos incentivos visando ao alinhamento com o nível de desenvolvimento da área nos países mais avançados.

Palavras-chave: Artigos científicos no Brasil, Literatura de Finanças, Produtividade dos autores em Finanças, Periódicos de Finanças, Capes.

ArtigosOwnership concentration, top management and board compensation

Revista de Administração Contemporânea, v. 17, n. 3, pp. 304-324. Abstract: The degree of ownership concentration may influence executive and board compensation (Bebchuk & Fried, 2003). This article analyzes this relationship. Detailed information about top management and board compensation became available starting in 2010 through new Securities Commission filings. Linear regression models applied to a sample of 315 Brazilian companies traded on the national exchange indicate a negative and statistically significant economic correlation between executive compensation and the degree of ownership concentration. Ceteris paribus, companies with a lower degree of ownership concentration pay higher compensation to top executives. Family controlled companies pay more to their chief executive, but not to the managerial team as a whole, and the compensation of directors increases with a greater proportion of control group members or their relatives on the board. There was support for the Managerial Power Hypothesis in companies with a lower degree of ownership concentration and for the extraction of private benefits in companies where it is greater.

Keywords: Executive compensation, Ownership concentration, Corporate governance, Agency costs, Managerial power hypothesis.

ArtigosBlack swans in the Brazilian stock market

Pesquisa Operacional, v. 33, n. 2, pp. 235-250. Abstract: This study analyzes extreme values in the daily returns of 45 Brazilian stocks between 2 January 1995 and 18 March 2009. The incidence of observations outside the range of three standard deviations from the mean is at least five times greater than under the normal distribution. The occurrence of extreme values in the upper tail is 1.13 times higher than in the lower. The average of the extreme positive returns is higher than that of extreme negative returns. Half percent of the days determined the outcome of the investment. Extreme values are at least ± 7%. Investors should assess whether they will keep their holdings when returns of such magnitude occur. The characteristics of empirical distributions of stock returns favor the passive investor and the use of weight constraints in portfolio allocation models.

Keywords: Extreme values, Normal distribution, Stock risk and return.

ArtigosAssessing the effect of tail dependence in portfolio allocations

Applied Financial Economics, v. 23, n. 15, pp. 1249-1256. Abstract: Portfolio selection requires an estimate of the degree of association between assets. The Pearson correlation coefficient ρ is the most common measure and estimates the linear correlation implied by the underlying bivariate distribution. Correlations typically rise during stressful times and this nonlinear dependence is measured by a nonzero tail dependence coefficient. We investigate the effect of tail dependence on the estimate of the correlation coefficient. Simulations show that extreme joint losses or gains cause overestimation of the linear correlation coefficient in the presence of tail dependence. The degree of association during the usual days may be smaller than that indicated by the sample correlation coefficient, impacting long-run investments. Simulations show that portfolios based either on the rank correlation or on a conditional version of the Pearson correlation outperform those obtained with classical inputs for moderate and weak strengths of tail dependence association computed from 5 or 10 years of daily data. However, the Pearson correlation coefficient is hard to beat for shorter time horizons and stronger strengths of tail dependence. We recommend estimating the copula pertaining to the data on the presence of tail dependence to select the most suitable correlation coefficient.

Keywords: Conditional correlation coefficient, Rank correlation coefficient, Markowitz mean-variance model, Copulas, Tail dependence.

ArtigosDifferences in outsourcing strategies between firms in emerging and in developed markets

International Journal of Operations & Production Management, v. 33, n. 3, pp. 296-321. Abstract Purpose: The vast majority of literature relating to operations management originates from studies in developed markets. Emerging markets are increasingly important in global business. With this in mind, the purpose of this paper is to analyze differences in outsourcing strategies between manufacturing firms from emerging markets and from developed markets. Design/methodology/approach: The paper is based on statistical analyses of a large data set of manufacturing firms obtained from the International Manufacturing Strategy Survey (IMSS). Findings: The findings suggest that companies that outsource internationally focus on achieving cost benefits, while companies that outsource domestically focus on achieving capacity flexibility. In addition, the reasons to outsource were found to be independent of the location of firms in both emerging and developed markets. However, within the group of firms from emerging markets, strategies seem to differ according to whether firms are domestically owned or are subsidiaries of companies from developed markets. Practical implications: The decisions of firms to outsource do not differ much whether the firms are located in developed‐ or in emerging‐market economies. Firms outsource domestically when they want to increase their capacity flexibility; they outsource internationally when looking for cost advantages. Originality/value: The value of the paper is that it illuminates an important contemporary phenomenon based on analyses on data from a large‐scale international survey encompassing firms both in developed and in emerging markets.

Keywords: Operations strategy, Outsourcing, Globalization, Survey research, Emerging markets.

ArtigosPlanejamento de redes logísticas: Um estudo de caso na indústria petroquímica brasileira

Revista de Administração Mackenzie, v. 14, n. 4, pp. 222-250. Resumo: O planejamento de redes logísticas emerge como decisão estratégica a ser tomada na busca da manutenção da competitividade empresarial. O presente estudo desenvolveu um modelo de Programação Não Linear Inteira Mista contemplando os principais componentes de custo envolvidos no processo de planejamento de redes associados à realidade brasileira: transportes, estoques e tributos. O modelo foi testado na empresa Nova Braskem. Foram realizadas análises de sensibilidade em que se apreciaram os principais trade-offs relativos às premissas assumidas. Constatou-se que, no caso estudado, o modelo desenvolvido proporciona economia nos custos tributários e nos custos logísticos de transporte, e, consequentemente, nos custos totais. Mais precisamente, os resultados apontam que, apesar da importância dos custos de transporte ante os demais, o aspecto fiscal se apresentou como o principal potencial de retorno financeiro a ser perseguido, e, dessa maneira, foi possível demonstrar o valor associado à questão dentro da atmosfera empresarial brasileira. Para o design ótimo de uma rede, confirma-se, portanto, a tese de que não é plausível a dissociação entre logística e planejamento tributário. Ademais, dada a natureza do estudo de caso, é factível a consideração do planejamento de redes logísticas como um importante ferramental capaz de subsidiar a busca de sinergias em operações de fusões e aquisições de empresas. Há, por exemplo, diversos outros casos recentes no cenário empresarial brasileiro, como a fusão entre Sadia e Perdigão e entre outras empresas do agronegócio. Para dar continuidade aos estudos dos trade-offs entre logística e os aspectos tributários brasileiros, sugere-se a inclusão de novos tributos (PIS, Cofins etc.) e a concessão de benefícios fiscais na modelagem de redes logísticas futuras. Especificamente com relação ao estudo de caso, observa-se que a forma de agregação dos mercados consumidores deve ser aprimorada, uma vez que a disposição de clientes na indústria petroquímica é bastante pulverizada. A correlação entre as demandas igualmente poderia ser analisada em um estudo de caso futuro. Finalmente, a fim de examinar as conclusões encontradas, sugere-se a aplicação do modelo desenvolvido em outros estudos de caso.

ArtigosPhysical infrastructure and shipment consolidation efficiency drivers in Brazilian ports: A two-stage network-DEA approach

Transport Policy, v. 29, pp. 145-153. Abstract: Port efficiency has been widely studied using standard DEA (Data Envelopment Analysis) models and its variations. As a matter of fact, these models do not account for the internal structure relative to measures characterizing port operations performance. In this paper, efficiency in Brazilian ports is measured using a two-stage process. In the first stage, called physical infrastructure efficiency, assets (number of berths, warehousing area, and yard area) are used to accomplish a certain shipment frequency per year. In the second stage, called shipment consolidation efficiency, these movements allow solid bulk and containerized cargoes to be handled. The network-DEA centralized efficiency model is adopted here to optimize both stages simultaneously. Results indicate that a private administration exerts a positive impact on physical infrastructure efficiency levels, while the hinterland size and the operation of both types of cargoes have a positive impact on shipment consolidation efficiency levels. Policy implications for the new regulatory framework on the Brazilian port sector are also derived.

Keywords: Ports, DEATwo-stage, Brazil, Intermediate measure, Centralized.

ArtigosPhysical infrastructure and flight consolidation efficiency drivers at Brazilian airports

Journal of Air Transport Management, v. 31, pp. 1-5. Abstract: Efficiency in Brazilian airports is measured using a two-stage process. In the first stage, physical infrastructure efficiency, assets, such as terminal area, aircraft parking spaces, and runways are related to the number of landings and take-offs per year. The second focuses on flight consolidation efficiency in terms of the number of passengers carried and cargo handled per year. A network-DEA centralized efficiency model is used to optimize the stages simultaneously. Results indicate that contextual variables or efficiency drivers, such as hub operations and airport location, impact physical infrastructure and flight consolidation efficiency levels differently.

ArtigosEvaluating efficiency in the Brazilian trucking industry

Production, v. 23, n. 3, pp. 508-524. Abstract: The purpose of this study is to investigate the issue of efficiency in the Brazilian motor carrier industry using both DEA (Data Envelopment Analysis) and SFA (Stochastic Frontier Analysis) in a complimentary fashion. The study is based on secondary data collected from Transporte Moderno/Maiores e Melhores, a specialized magazine that annually reports statistics on the largest Brazilian trucking companies. Results corroborate not only that increasing returns to scale prevail within this industry, but also provide support for a moderate impact of economies of scope on efficiency levels. Implications in terms of mergers and acquisitions and the impact of cargo diversity and the geographical scope of the operation on virtual efficiency levels are also addressed.

Keywords: Trucking industry; Data envelopment analysis; Three-stage modeling; Stochastic frontier analysis; Mergers.

ArtigosMade in China: um estudo sobre o “Efeito país de Origem” na introdução da Montadora Chery no Brasil

Revista ADM.MADE, v. 17, n. 3, pp. 149-168. Resumo: O presente estudo investiga o efeito de país de origem no processo de introdução de marcas em novos contextos nacionais, a partir da análise do caso da marca Chery e de sua chegada ao mercado brasileiro. Para isso, utiliza-se abordagem qualitativa, a partir da netnografia, com o objetivo de compreender como as comunidades relacionadas à Chery elaboram significados positivos e negativos em relação à marca. A pesquisa evidencia que a marca Chery esteve fortemente associada à China, algo que pode ter sido reforçado pela entrada simultânea de outras montadoras chinesas no país (JAC e Lifan). O trabalho propõe uma tipologia de consumidores a partir de duas dimensões distintas: i) relação do consumidor internauta com a marca, e ii) conhecimento técnico a respeito de carros. Assim, descreve os perfis “apaixonado”, “embaixador”, “revoltado” e “depreciador”. O trabalho analisa ainda a estratégia de oferta de carro completo, e como ela é discutida a partir do conceito de cidadania e do direito do consumidor.

Palavras-chave: Efeito país de origem, Automóveis, Chery, Netnografia.

ArtigosO método do caso e a sua importância na formação de gestores no contexto brasileiro

Revista FSA (Faculdade Santo Agostinho), v. 10, n. 1, pp. 1-24. Resumo: Os métodos passivos de ensino têm sido questionados por suas limitações no desenvolvimento da capacidade de análise e senso crítico dos alunos. O modelo centrado no professor mostra-se inadequado ao ensino de Administração quando se entende que um dos principais objetivos da educação nessa área de conhecimento não está só na troca de informações, mas principalmente na formação de indivíduos capazes de pensar de maneira independente e criativa a realidade dos negócios. Uma das alternativas utilizadas por diversas escolas americanas e européias é o método do caso. Esse trabalho procura discutir a adequação dessa metodologia ao ensino de administração no Brasil, os requisitos básicos para a sua utilização e o papel do professor nesse modelo. Para isso, utiliza, ele próprio, de um caso e sua proposta de análise. Trata-se de um material do tipo “armchair”, criado a partir das experiências das autoras. A proposta é fornecer um instrumento a ser utilizado em workshops ou seminários que apresentem esse método de ensino para professores e/ou alunos.

ArtigosA heurística do afeto e o conceito de “avaliabilidade”: Experimentos no contexto brasileiro

Revista Brasileira de Marketing-REMark, v. 12, n. 2, pp. 29-48. Resumo: Na literatura recente, encontramos a denominada affect heuristic: respostas afetivas que ocorreriam rápida e automaticamente, servindo de “atalho mental” nos processos de decisão (Slovic et al, 2002). Bateman et al. (2007) examinaram o papel do afeto in determinar julgamentos e decisões e apresentaram resultados experimentais demonstrando que a introdução de uma pequena perda como um componente de um jogo pode aumentar a atratividade do jogo. Neste estudo, nós replicamos os experimentos de Bateman et al. (2007), com resultados similares e discutimos o conceito de “avaliabilidade” (Hsee, 1996, 1998, Slovic et al, 2002 e Bateman et al, 2007), para explicar esses resultados. No geral, os resultados demonstram a importância de fatores contextuais na determinação das impressões afetivas e oferecem suporte para a proposição que destaca a importância da heurística do afeto em processos de julgamento e tomada de decisão.

ArtigosReconciliando o modelo de Uppsala com a perspectiva de networks: Revisão crítica e integrativa

Revista de Administração FACES Journal, v. 12, n. 2, pp. 13-36. Resumo: O modelo de Uppsala (M-U) é uma das mais importantes abordagens teóricas de processos de internacionalização e recentemente ele foi extensivamente atualizado. O objetivo deste artigo foi analisar a evolução do M-U original até o revisado, que incluiu definitivamente a perspectiva de networks. Foram levantadas as críticas ao modelo baseadas nessa perspectiva, apresentada sua base conceitual e sua contribuição ao M-U. Ao explicar as premissas e o mecanismo de internacionalização do modelo revisado, pode-se chegar à conclusão que este apresenta maior poder explicativo que o modelo original, especialmente no estudo dos processos de  internacionalização precoces e acelerados das empresas chamadas de Born Globals, pois diminui a importância da cadeia de estabelecimento, revalida o conceito de distância psíquica e destaca os relacionamentos de network. Porém, criticamente, é possível apontar que o M-U ainda necessita integrar conceitos de empreendedorismo, e ampliar seu escopo para além das pequenas empresas.

ArtigosCriação coletiva na Web 2.0: Um estudo de caso em uma empresa brasileira de Crowdsourcing

Revista Eletrônica de Sistemas de Informação, v. 12, n. 3, pp. 1-22. Resumo: Este trabalho discute como a participação dos consumidores nos negócios evoluiu nos últimos anos, deixando de ser mera forma de otimizar os custos para tornar-se ferramenta estratégica de marketing ou gerar novos modelos de negócios. O engajamento em um estágio mais avançado dos denominados prosumers com as empresas foi viabilizado por variados fatores, tendo como elemento fundamental a evolução tecnológica. A chamada web 2.0 mudou o comportamento do consumidor que transita em comunidades online e que encontra novas ferramentas de engajamento nos processos de criação e produção. Algumas firmas perceberam que podem reduzir custos, riscos e, concomitantemente, ganhar potencial criativo ao envolver no processo de desenvolvimento de seus produtos clientes se interessam por produtos mais personalizados, pela troca de informações e que se sentem atraídos pela possibilidade de criação em ambientes virtuais colaborativos. Por meio de revisão da literatura, da análise de relatórios de empresas e de fontes secundárias da mídia, buscou-se descrever o processo de participação do cliente nesses processos. Peer production, inovação aberta, crowdsourcing, colaboração em massa e inteligência coletiva são alguns dos conceitos identificados na literatura para designar essa interação. Procurou-se organizar essas definições, de forma cronológica, explicitando algumas aplicações nos negócios. O trabalho adota, então, a metodologia de estudo de caso para investigar o uso de um modelo baseado em crowdsourcing, em uma empresa brasileira de camisetas. Uma análise inspirada na netnografia auxilia a aprofundar o entendimento do fenômeno a partir do estudo de caso. O estudo é finalizado com uma síntese das oportunidades e desafios da criação coletiva, propondo possibilidades de pesquisas para melhor avaliação do processo no contexto brasileiro.

ArtigosAnálise estratégica do mercado brasileiro de Application Service Providers (ASP)

Revista Eletrônica do Alto Vale do Itajaí, v. 2, n. 2, pp. 101-127. Resumo: Um Application Service Provider (ASP) é uma empresa que provê um serviço mediante contrato para disponibilizar, hospedar e gerenciar aplicativos para clientes remotos. Este modelo de negócios foi possibilitado pelos avanços nas tecnologias de informação e comunicação, sendo especialmente atraente para empresas de médio e pequeno porte. Embora recente, do final dos anos 1990, na segunda década do século XXI o termo já está em desuso e sendo substituído por Software as a Service (SaaS). O modelo enfrentou e ainda enfrenta dificuldades para sua adoção no Brasil e no mundo e este trabalho apresenta uma análise estratégica que procura detalhá-lo mais e mostrar como se tentou adaptá-lo ao mercado brasileiro na primeira década do século XXI. Foi feita uma extensa pesquisa de campo, com entrevistas a diversos executivos, buscando-se identificar as principais questões que estavam envolvidas na disseminação do modelo. Para a análise da indústria de ASPs foram utilizados os conceitos mais difundidos de análise estratégica, principalmente os de Porter (1979 e 1985), com o modelo de análise competitiva – “Cinco Forças” – e de “Estratégias Genéricas”. Entretanto, ficou claro que outros conceitos precisariam ser levados em consideração para capturar as complexidades estratégicas do setor, notadamente a noção de “complementadores” e a busca de estratégias outras que não competir simplesmente para ter o “melhor produto”.

ArtigosMarketing interno e gestão de pessoas: Estudos de caso em empresas de serviços

Revista Gestão & Tecnologia, v. 13, n. 3, pp. 101-127. Resumo: O conceito de marketing interno surgiu em empresas de serviços nos Estados Unidos como forma de estimular os funcionários a melhorar a qualidade na prestação de serviços. À medida que o conceito se desenvolveu, passou a focar aspectos relacionados a implementação de estratégias, geração de mudanças e orientação para o mercado. Em todos esses pontos, o empregado ocupava um papel de destaque, evidenciando uma possível convergência entre ações de marketing interno e práticas de gestão de pessoas. Nesse sentido, o presente estudo busca discutir a relação entre marketing interno e gestão de pessoas a partir de dois estudos de caso em empresas de serviços que declaradamente adotavam ações de marketing interno. Os resultados permitiram observar que essa relação ocorria por meio de diferentes atividades de recrutamento e seleção, treinamento e desenvolvimento, gestão do desempenho e recompensas.

ArtigosHedonismo e moralismo: Consumo na base da pirâmide

Revista de Administração de Empresas, v. 53, n. 2, pp. 199-207. Resumo: A estabilidade econômica no Brasil permitiu que itens acessíveis somente às classes sociais mais abastadas fossem consumidos na “base da pirâmide”. Tal fato despertou interesse acadêmico e empresarial por melhor compreender esse fenômeno. Duas linhas argumentativas surgiram, com distintas perspectivas. Enquanto uma defende um discurso hedonista, ao incentivar o consumo pela base da pirâmide, como forma de diminuir a pobreza, a outra, cuja perspectiva dominante é moralista, critica tal visão, pois acredita que somente a inserção das pessoas com menor poder aquisitivo no processo de produção contribuirá para melhorar suas vidas. Um dos objetivos do presente ensaio é, portanto, discutir como a literatura sobre o consumo na base da pirâmide apresenta elementos desses tipos de discursos. Além disso, busca-se estimular mais estudos, propondo uma agenda inicial de pesquisa.

Palavras-chave: Hedonismo, Moralismo, Pobreza, Consumo, Renda.

ArtigosEstudos de consumo: um convite para a riqueza e para a simplicidade da pesquisa de rituais brasileiros

Revista ADM.MADE, v. 17, n. 3, pp. 27-46. Resumo: O objetivo deste ensaio teórico é explorar a presença de estudos sobre rituais no campo de comportamento do consumidor, enfatizando a sua contribuição às pesquisas brasileiras de estudos de consumo que possuem dimensões culturais, simbólicas e coletivas. Para tanto, posiciona-se historicamente o campo de estudo do comportamento do consumidor evidenciando -se a decorrente compreensão de temas antes não abarcados em seu domínio, como o dos rituais de consumo. Posteriormente, discute-se o conceito de ritual por diferentes autores da área de estudos de consumo, e também a acomodação do tema na Consumer Culture Theory (CCT). Ao final, o ensaio percorre estudos sobre rituais no Brasil, em destaque na área de Administração, e defende que seja dada maior relevância a esse tema, dada as diversidades existentes no País, para que melhor se entenda a sociedade de consumo brasileira.

ArtigosEstética e consumo: Estudando duas tribos urbanas cariocas

Revista Pensamento Contemporâneo em Administração, v. 7, n. 1, pp. 122-141. Resumo: A pesquisa foi motivada pela crescente importância dos estudos sobre o fenômeno do tribalismo urbano para o Marketing. Alguns desses estudos indicam que produtos e marcas podem ser apropriados pelos membros da tribo para a criação de uma identidade. Nesse contexto, definiu-se como objetivo deste estudo investigar e confrontar padrões estéticos e práticas de consumo adotadas por duas tribos urbanas identificadas com o dia e com a noite na cidade do Rio de Janeiro. A tribo do dia foi escolhida a partir da praia não só pela importância social, cultural e econômica que as praias assumem no Rio de Janeiro, mas também pelo fato de a praia ser o valor de ligação entre pessoas de diversos locais do Rio, particularmente das áreas mais nobres da cidade. Já a tribo da noite foi composta por frequentadores de bailes de black music. A análise desses grupos sugere que eles apresentam padrões estéticos específicos e distintos, que servem como forma de identificação entre os membros de cada grupo. Os resultados também apontaram que o consumo de determinados produtos está relacionado com os valores de ligação das tribos investigadas.

Palavras-chave: Tribos urbanas. Estética. Práticas de consumo.

ArtigosConsumo consciente como determinante da sustentabilidade empresarial: respeitar os animais pode ser um bom negócio?

Revista de Administração da UFSM, v. 6, n. Edição Especial, pp. 861-877. Resumo: Este estudo exploratório tem como objetivo compreender as reações dos consumidores em relação aos maus tratos praticados contra os animais em processos industriais de produção de carne, os quais geram dor, sofrimento e estresse. O estudo utiliza metodologia quantitativa, com uma survey através da internet, que conta com a utilização de um vídeo que ilustra práticas industriais de criação de animais utilizadas para acelerar o processo de produção e aumentar a produtividade, tais como espaço mínimo e amputações de membros. Além de tentar avaliar o grau de conhecimento que os consumidores têm sobre esses procedimentos, a pesquisa busca identificar o potencial de mudança de hábitos de consumo decorrente do contato com a nova informação. O estudo mostra que, em geral, os consumidores não têm conhecimento sobre os padrões de manejo para a produção de carne. Após terem acesso a imagens das fazendas industriais, mudam sua percepção, o que pode indicar uma ameaça para as empresas que mantiverem os processos e modelos de negócios atuais. Além disso, consumidores se mostram propensos a pagar preços mais elevados por produtos certificados, que assegurem ausência de maus tratos aos animais, sinalizando para as empresas a existência de uma oportunidade de mercado.

Palavras-chave: Sustentabilidade corporativa; Consumo consciente; Bem-estar animal; Selos de certificação.

ArtigosEscolha de tecnologia em organizações de saúde: proposta de um Modelo de Análise

Revista Gestão & Tecnologia, v. 13, n. 2, pp. 21-44. Resumo: A enorme importância econômica da tecnologia utilizada nas operações industriais e de serviços sugere que o processo de escolha da tecnologia deva ser estudado com grande cuidado. No entanto, uma análise da literatura sobre o assunto mostra que, embora já exista um grande número de estudos na área de operações industriais, o mesmo não acontece na área de serviços e, menos ainda, na área da saúde. Assim, o objetivo do presente trabalho é o de desenvolver um modelo de escolha de tecnologia em organizações de saúde baseado na literatura, tanto da área da saúde, como da área da indústria (visto que esta última já apresenta um razoável número de estudos). Primeiramente, foi feita uma revisão bibliográfica da literatura sobre escolha de tecnologia. Em segundo lugar, a revisão focou os poucos artigos sobre adoção de tecnologia em instituições de saúde. Verificou-se que a maior parte da literatura tem origem na Economia, sugerindo maiores pesquisas que auxiliem os gestores das organizações de saúde no processo de escolha e adoção de novas tecnologias. Em terceiro lugar, fez-se uma busca na literatura de comportamento de compra organizacional. O resultado de tais revisões é um modelo prescritivo que considera todas as variáveis selecionadas da literatura nas diversas etapas da pesquisa. É apresentado o Modelo de Escolha de Tecnologia em Saúde (METS) explicando-se a relação entre as suas variáveis e a escolha de tecnologia. A discussão denota a utilidade do modelo tanto para empresas fornecedoras quanto para empresas adotantes de novas tecnologias.

Palavras-chave: Escolha de tecnologia, Transferência de tecnologia, Gestão de organizações de saúde, Gestão de compras, Gestão de operações e logística.

ArtigosCasos de ensino no Brasil: Análise bibliométrica e orientações para autores

Revista de Administração Contemporânea, v. 17, n. 2, pp. 176-197. Resumo: A demanda pela utilização de métodos participativos de ensino vem aumentando em cursos de administração. Correspondentemente, cresce o número de professores que utilizam esse método por meio de casos. Como forma de incentivar a disseminação de casos brasileiros, em 2007, a Associação Nacional de Pós-Graduação e Pesquisa em Administração (ANPAD) passou a aceitar casos de ensino em seus congressos. A presente pesquisa tem por objetivo propor diretrizes para acadêmicos brasileiros em administração que desejem produzir casos de ensino, a partir de um panorama da produção dos casos nacionais publicados entre 2007 e 2011. Foi realizada uma análise bibliométrica acerca das publicações nos eventos da ANPAD e nos principais periódicos nacionais. Os resultados apontaram que os maiores problemas ocorrem nas notas de ensino. A maioria dos casos é considerada pelos autores como útil para as áreas de estratégia e de marketing, porém há áreas que contam com poucos casos, como gestão de pessoas, logística e finanças. A análise alertou para a predominância de um perfil de protagonista e para a falta de diversificação das fontes de dados utilizadas para a elaboração dos casos. O artigo traz 16 diretrizes com o propósito de orientar acadêmicos brasileiros que desejem produzir casos de ensino em administração.

Palavras-chave: Casos de ensino, Bibliometria, Diretrizes.

ArtigosImpacts of a relationship model on informational technology governance: an analysis of managerial perceptions in Brazil

JISTEM – Journal of Information Systems and Technology Management, v. 10, n. 3, pp. 621-642. Abstract: The aim of this article is to analyze the impacts, based on the perceptions of managers, of the deployment of a model to govern the relationship between business areas and IT in a large Brazilian financial organization.  To undertake the case study of this deployment, the research firstly performed documental analyses of the process and then sent electronic surveys to a sample of managers in order to evaluate their perceptions of the model’s impact in terms of the formalism of the organization’s internal processes, strategic alignment between business areas and IT and levels of governance in the organization.  The results revealed that managers perceived improvements in the quality of technological solutions, levels of IT governance, the understanding of IT area needs and business area demands, but they also stated that the negotiating process was more complex and there was no increase in their level of satisfaction with IT. These results of the study may contribute to the development of instruments for the evaluation of the impacts of the deployment of relationship models on important organizational aspects.

ArtigosHow to better identify and measure R&D in services: Constraints in Brazilian hospitals

International Journal of Innovation and Technology Management, v. 10, n. 3. Abstract: This paper proposes a reflection to induce a better understanding of R&D in services, based on case studies carried out in Brazilian University Hospitals (UHs). The results show that the generation and increase of the stock of knowledge in services go beyond those reported in the material component. We also found that a diversity of actors contributed in an informal way to these dynamics. Concerning R&D funding, we noticed that service R&D is not always planned through a formal project. Then we suggested expanded R&D indicators which seems to contribute to the improvement of statistics related to R&D in services.

Keywords: Service R&D, R&D indicators in services, Hospital service sector.

ArtigosA sociotechnical perspective on innovation in services

Revista de Administração FACES Journal, v. 12, n. 4, pp. 84-99. Abstract: The objective of this paper is to discuss the concepts of services, innovation and Techno-Economic Networks (TEN) and to come up with a sociotechnical framework to the analysis of innovation in the service sector. Two presuppositions serve as guidelines for this analysis: first, service may be seen as a socio-technical result and, therefore, suitable to be studied in an integrative innovation approach; second, the TEN has a socio-technical view of innovation phenomena, without a dualistic view of technological and non-technological innovations. Concepts of innovation are discussed and this is followed by a discussion of the characteristics of services and the TEN, in order to articulate this approach for research work in the service sector. The paper involves a proposal consisted in exploring and describing pertinent literature to the theme, as well as making proposals that may become component issues for a agenda in the innovation in services research field.

Keywords: Services, Innovation, Innovation in services, Techno-Economic Network, Actor-Network Theory.

ArtigosA ciência da inovação em serviços: estudo exploratório sobre os interesses e prioridades para uma agenda de pesquisa no Brasil

INMR – Innovation & Management Review, v. 10, n. 4, pp. 110-135. Resumo: Após uma revisão teórica em que foi identificada a relevância do avanço do conhecimento nos campos analíticos de ciência de serviços e inovação, o artigo apresenta resultados de um estudo exploratório no Brasil, a partir da operacionalização de um mapeamento dos interesses e a percepção das prioridades do emergente campo científico de Ciência de Serviços. Adotando como parâmetro a principal pesquisa conduzida nos EUA sobre o tema, a das proposições de prioridades de pesquisa em ciência de serviços do grupo Center for Services Leadership – CSL da Universidade do Estado do Arizona, em que foram definidas dez áreas prioritárias para pesquisa em Ciência de Serviço (Ostrom et al., 2010), foi realizada uma pesquisa anônima com os membros da nascente comunidade brasileira de Ciência de Serviços e os autores do 1o Simpósio Brasileiro, integrantes da academia e da iniciativa privada (103 respondentes). Os resultados revelam grande interesse em questões práticas ao universo empresarial, como criação de modelos de negócios para exploração de novas tecnologias de serviços, instrumentos e métricas de mensuração para a criação de valor, formalização das atividades para gestão da inovação e rotinas de P&D e métodos de aperfeiçoamento da qualidade nas áreas da saúde e educação. O interesse pelo tema da sustentabilidade e inclusão social foi manifestado pela maior ênfase nos tópicos sobre melhoria e universalização do bem-estar social. Os resultados deste estudo indicam a percepção da comunidade científica em relação às melhores estratégias de investimento públicas e empresariais para a condução de futuras linhas de pesquisa no Brasil.

ArtigosTruth or consequences: The effects of competitive-unethical tactics on negotiation process and outcomes

International Journal of Conflict Management, v. 24, n. 4, pp. 328-351. Abstract Purpose: This paper aims to describe a study of the negotiation process, focusing on the use of seven competitive-unethical tactics in dyadic negotiations. The initial use of these tactics and their effects on process and outcomes are examined. Design/methodology/approach: In total, 230 Brazilian professionals from a large financial institution participated in two-party, property-leasing negotiations involving eight issues with assigned point values. Negotiations were conducted online and, from the recorded transcripts, seven competitive-unethical tactics were tracked and analyzed with respect to the negotiation process and outcomes (individual and joint, perceived and actual). Findings: The study found that most participants employed one or more tactics, the stage and incidents of initial use affected overall employment, and participants often reciprocated when tactics were employed. Reciprocation was best described by a logarithmic function, with a small number of tactics answered with as many or more tactics, but a large number of tactics producing a smaller response. Also, number of messages exchanged and number of tactics per message were related to likelihood of reaching an agreement and, to some extent, to individual outcomes (actual and perceived). Reaching an agreement and perceived individual outcome were associated with a participant’s desire to negotiate with a counterpart in the future. Originality/value: The vast majority of studies to date have employed questionnaires to measure ethical attitudes or intentions, or have limited their empirical studies to competitive tactics only. This study moves beyond these methodologies to examine the actual use of a range of competitive-unethical tactics, and their effects on process and outcomes.

Keywords: Ethics, Negotiation.

ArtigosTipos de riesgos percibidos en el proceso de compra de billetes aéreos

Estudios y Perspectivas en Turismo, v. 22, n. 1, pp. 47-64. Resumen: Internet ha cambiado la forma en que los consumidores compran los productos de viajes, mediante la sustitución de las agencias convencionales por los sitios web. Sin embargo, muchos clientes todavía perciben riesgos en las compras realizadas a través de Internet. Así, el objetivo de este estudio es evaluar si la percepción de los diferentes tipos de riesgo (financiero, de desempeño, social, físico, psicológico y pérdida de tiempo) varía en función del canal de venta utilizado, o a lo largo de las diferentes etapas del proceso de compra. Se realizó una encuesta em Internet, generando 184 cuestionarios válidos. Los resultados muestran que los consumidores perciben un mayor riesgo financiero en la compra a través de Internet y un menor riesgo físico y pérdida de tiempo en ese canal a la hora de comprar en las agencias convencionales. Además, se observó que los compradores de billetes de avión a través de Internet perciben un menor riesgo em las etapas de búsqueda de información y evaluación de alternativas en relación con el canal convencional y que esta diferencia no existe en la etapa de la decisión de compra.

Palabras-clave: Percepción de riesgo, Compras por internet, Billetes de avión.

ArtigosTipos de falhas, práticas de recuperação e a fidelização de clientes de serviços hospitalares

Revista de Gestão em Sistemas de Saúde – RGSS, v. 2, n. 2, pp. 3-29. Resumo: Este artigo apresenta resultados de pesquisa realizada em dois hospitais de Vitória, ES, Brasil, procurando compreender como clientes de serviços de saúde percebem a ocorrência de falhas e as práticas de recuperação adotadas. Utilizando a Técnica do Incidente Crítico, foram analisadas 311 entrevistas pessoais. As 555 falhas de serviços identificadas foram classificadas de acordo com o modelo proposto com base na revisão de literatura. Em apenas 2% dos relatos, os esforços de recuperação foram satisfatórios na percepção dos clientes. Apesar desse baixo percentual, 62% dos clientes recomendariam os serviços do hospital onde a falha ocorreu.

Palavras-chave: Hospital; Recuperação do Serviço; Falhas em Serviços de Saúde; Fidelização de Clientes.

ArtigosImpactos do sistema de informação geográfica na administração pública

Gestão & Produção, v. 13, n. 1, pp. 3-21. Resumo: Nos países em desenvolvimento, as prefeituras municipais têm enfrentado restrições orçamentárias, que demandam a tomada de decisão de investimentos de forma consciente, priorizando áreas essenciais à população. Como a maioria das questões possui uma componente locacional, tem-se intensificado a adoção de ferramentas baseadas em Sistema de Informação Geográfica (GIS). O objetivo geral desta pesquisa é analisar como se dá o processo de adoção do GIS, através do estudo de caso da Prefeitura da cidade de Vitória (ES), Brasil. Os resultados indicam que as inovações em processos somente serão bem sucedidas se enfrentarem a falta de vontade e de comprometimento políticos dos gestores municipais.

ArtigosAvaliação de empresas start-up por opções reais: O caso do setor de biotecnologia

Gestão & Produção, v. 20, n. 3, pp. 511-523. Resumo: Este trabalho avaliou uma empresa start-up de biotecnologia à luz da teoria de Opções Reais. O objetivo principal foi averiguar a adequação deste modelo na avaliação de empresas inovadoras, sujeitas a grande risco, de forma a captar o valor das flexibilidades gerenciais presentes neste tipo de empreendimento. Para verificar a subavaliação provocada pelo método de Fluxo de Caixa Descontado ao desconsiderar o valor das opções, foi realizado um estudo de caso na empresa BioNatural, incubada no Polo BioRio de Biotecnologia, localizado no campus da Universidade Federal do Rio de Janeiro. Os resultados da avaliação financeira de um projeto de pesquisa específico indicaram uma subavaliação da ordem de 16%. Os resultados reforçam a visão de que a Teoria de Opções Reais pode ser mais adequada para avaliar empreendimentos sujeitos a extrema incerteza, captando um valor não mensurado pelas técnicas tradicionais de avaliação de projetos.

Palavras-chave: Avaliação de projetos; Opções Reais; Biotecnologia; Empresas start-up.

ArtigosIncentivos da regulação de mercados sobre o nível de suavização de resultados

Contabilidade Vista & Revista, v. 24, n. 2, pp. 110-136. Resumo: Este estudo investiga se os incentivos advindos da regulação dos mercados exerce alguma influência sobre o nível de suavização de resultados das empresas brasileiras. Dessa maneira, parte-se do pressuposto de que os gestores podem se utilizar das práticas de suavização de resultados para reduzir a variabilidade dos lucros divulgados ao mercado, na tentativa de reportar uma visão mais estável do negócio, evitando assim uma possível intervenção ou coerção indesejada pelas agências reguladoras. Metodologicamente, compara-se e descreve-se o nível de suavização de resultados por setor da economia, segregando-os em regulados e não regulados. A amostra é composta pelas sociedades anônimas com ações negociadas na BM&FBovespa no período entre 1996 a 2009. Os modelos aplicados para detectar a presença de suavização de resultados foram os modelos desenvolvidos por Eckel (1981) e três medidas de Leuz et al. (2003). Foram aplicados testes de média para verificar se existe diferença estatisticamente significante entre os grupos de setores regulados e não regulados. As evidências revelam que os setores não regulados apresentaram um maior nível de suavização, demonstrando que a regulação exercida por agências brasileiras (ANEEL, ANATEL, ANP, ANTT e ANTAQ) não criou um incentivo adicional para a suavização de resultado. Assim, pode-se dizer que o processo de regulação proporciona um efeito contrário, ou seja, fornece incentivos para menor intervenção nos resultados contábeis que procurem reduzir a variabilidade dos lucros divulgados ao mercado.

Palavras-chave: Regulação, Suavização de resultados, Variabilidade dos lucros, Agências Reguladoras.

ArtigosEfeitos da adoção da ICPC 01 E IFRIC 12 na formação das tarifas de concessionárias do setor de saneamento básico

Advances in Scientific and Applied Accounting, v. 6, n. 3, pp. 265–293. Resumo: O objetivo desta pesquisa é identificar efeitos da adoção da ICPC 01 e IFRIC 12 na formação das tarifas de duas importantes concessionárias de serviços públicos pertencentes ao setor de saneamento básico brasileiro, Companhia de Saneamento de Minas Gerais – COPASA e Companhia Estadual de Águas e Esgotos – CEDAE. Foram confrontados informações e dados relativos às mudanças de critérios contábeis introduzidas pela ICPC 01 e IFRIC 12 com as informações atinentes à metodologia aplicada para a formação das tarifas das empresas, com vistas a identificar uma possível relação entre as mudanças nas classificações e nos valores das contas patrimoniais e de resultado realizadas pelas empresas e as variáveis que constituem o cálculo do Índice de Reajuste Tarifário (IRT), diretamente relacionado à formação periódica de suas tarifas. Adotou-se o método de estudo de caso com o uso da técnica de análise de conteúdo. A análise da COPASA evidenciou que as mudanças de critério contábil realizadas pela empresa relacionadas à transferência do imobilizado para ativo financeiro e intangível e à adoção do prazo de concessão para amortização da infraestrutura pública influenciou o valor da depreciação e amortização de ativos pertencente ao cálculo tarifário. Por outro lado, o estudo com a CEDAE demonstrou que o modelo utilizado para o cálculo do IRT, baseado em variáveis extraídas do fluxo de caixa da empresa, é inflexível aos efeitos que podem ser gerados pelas mudanças contábeis introduzidas pela ICPC 01 e IFRIC 12, uma vez que essas variáveis não têm os seus valores alterados em função da adoção das normas.

ArtigosDivulgação nos relatórios dos bancos públicos brasileiros: análise das recomendações do Pilar 3 do Acordo de Basiléia 2

Revista de Administração Pública, v. 47, n. 6, pp. 1329 -1358. Resumo: Este artigo verifica o nível de divulgação praticado pelos bancos públicos brasileiros em relação às recomendações do Pilar 3 do Acordo de Basileia 2. Utilizou-se a técnica de análise de conteúdo, com exame, em 2010, das informações financeiras disponibilizadas no site do Banco Central do Brasil (Bacen) referentes aos quartos trimestres de 2008 e 2009. Os principais relatórios analisados foram as notas explicativas e o relatório da administração. As exigências de divulgação do Pilar 3 são apresentadas em 14 tabelas no Acordo, porém, este artigo utilizou as 9 tabelas com requerimentos de disclosure relacionados à aplicação das abordagens padronizadas. Os resultados indicaram que os níveis de divulgação foram de 25% em 2008 e de 29% em 2009 e referem-se exclusivamente às instituições pesquisadas incluídas na amostra. Em síntese, a demonstração dos bancos públicos apresenta um nível incipiente de transparência e, normalmente, restringe-se às informações exigidas pela legislação.

ArtigosInsatisfações projetadas de consumidores de baixa renda

Revista Pensamento Contemporâneo em Administração, v. 8, n. 4, pp. 65-84. Resumo: O presente estudo tem como objetivo estudar como consumidores de baixa renda reagem quando em situações de insatisfação de consumo. Utilizou-se, para isso, a técnica projetiva de histórias temáticas para a coleta de dados. Foram identificadas duas perspectivas sobre como o consumidor reage quando insatisfeito. A primeira, ilustra um comportamento passivo sobre como resolver problemas de consumo, que, em geral, significa não reclamar e se conformar com o prejuízo. A segunda, diferentemente, ilustra uma reação contra a insatisfação, expressa por reclamações ou, até, adoção de medidas legais. Diferentemente do que a literatura aponta, o presente trabalho mostra que há consumidores de baixa renda que reclamam quando insatisfeitos, pois conhecem, pelos menos em discurso, seus direitos de consumo. Empresas devem atentar para tais reações desses consumidores, fugindo da racionalidade de que eles abrem mão de atendimento de qualidade, por valorizarem mais preços baixos.

Palavras-chave: Insatisfação, Reclamação, Consumidor de baixa renda, Passivo, Reativo.

ArtigosEntre associativismo e regimes de engajamento: reflexões acerca do conceito de inovação social para pensar políticas públicas de inovação

Estudos De Sociologia, v. 19, n. 37, pp. 349-369. Resumo: O objetivo deste trabalho é revisitar o conceito de inovação social e discutir suas implicações para políticas públicas de inovação. Os efeitos dessas políticas permitem questionar quais alternativas podem ser mais eficazes no direcionamento da inovação para a solução de problemas econômicos e sociais que pode contrastar com concepções sistêmicas de inovação. É neste ponto que o conceito de inovação social pode tanto constituir base da crítica de políticas de inovação como apontar elementos para seu avanço. Com base em análise documental e revisão da literatura, analisamos o quadro de políticas de C&T&I no Brasil, ao longo do Governo Lula, apontando a necessidade de um conceito de inovação social que articule demandas sociais e econômicas. Contemplamos aspectos organizacionais, normativos e associativos que justifiquem o impulso às inovações sociais, assim como os regimes de engajamento de atores sociais na configuração de experiências socialmente inovativas.

ArtigosPropensão do cliente à proposição de ações judiciais: proposição e teste de modelo preditivo para o setor de energia elétrica

REMark – Revista Brasileira de Marketing, v. 13, n. 5, pp. 1-18. Resumo: O estudo objetivou a proposição e teste de um modelo predititivo da propensão de clientes de concessionárias do setor de energia elétrica à proposição de ações judiciais. Investigaram-se os efeitos: do perfil do cliente; dos motivos críticos de reclamação; e do histórico de ações administrativas, na propensão à proposição de ações judiciais. O corpo teórico do paradigma da desconfirmação de expectativas foi utilizado como referencial teórico do estudo. Adotou-se uma abordagem substantiva para o desenvolvimento e teste do modelo predititivo. A técnica de Árvore de Classificação foi escolhida para operacionalizar o modelo. O método especificado neste estudo para a criação da árvore de decisão foi o CHAID (Chi Square Interaction Detector). A análise dos dados permite concluir que a propensão à proposição de uma ação judicial não depende exclusivamente da natureza do problema enfrentado pelo cliente, mas do seu perfil e da sua trajetória de relacionamento com a concessionária. Os resultados do presente estudo adicionam suporte empírico ao corpo teórico do paradigma da desconfirmação de expectativas, mais especificamente, no que diz respeito à Teoria da Satisfação, Teoria da Atribuição e à Teoria da Justiça e Equidade. A principal contribuição gerencial do estudo reside na proposição de um modelo preditivo que permite atribuir a cada cliente uma probabilidade de proposição de ação judicial, o que possibilita a adoção de práticas antecipatórias por parte da concessionária, objetivando melhor servir ao público.

ArtigosEnvolvimento do Consumidor com o Produto: comparação das escalas PII e NIP no contexto brasileiro

Revista Brasileira de Gestão de Negócios, v. 16, n. 50, pp. 75-95. Resumo: O estudo objetiva avaliar o grau de convergência de classificação entre os escores de duas escalas de envolvimento do consumidor: PII (Personal Involvement Inventory) de autoria de Zaichkowsky (1994) e NIP (New Involvement Profile) de autoria de Jain e Srinivasan (1990). O referencial teórico contempla os principais estudos sobre a mensuração do envolvimento do consumidor com o produto. Os dados foram coletados por meio de uma survey aplicada a uma amostra não probabilística, selecionada por cotas, composta por estudantes de instituições de ensino superior do estado do Rio de Janeiro. Foram coletados 1.122 questionários, sendo 1.025 válidos (91,4%). Para investigar diferentes níveis de envolvimento dos consumidores em relação às categorias de produtos, foram utilizados quatro produtos − tênis, telefone celular, bebida esportiva e refrigerante. Utilizando-se a Anova e os testes post hoc, verificou-se a existência de diferenças significativas nas respostas entre os grupos de produtos. Para testar a hipótese substantiva do estudo, avaliou-se o grau de convergência de classificação das escalas PII e NIP utilizando-se o teste de correlação de Spearman, bem como a observação da proporção de coincidência de classificação dos escores. A independência dos escores foi avaliada por meio do teste Qui-quadrado. Os resultados suportam uma alta convergência de classificação dos casos. A contribuição principal do estudo reside, portanto, no teste empírico das escalas PII e NIP no contexto brasileiro. Adicionalmente, a convergência dos escores dessas escalas sugere a possibilidade de comparação de resultados de estudos, que utilizem quaisquer dessas escalas.

Palavras-chave: Comportamento do consumidor, Envolvimento do consumidor com o produto, Escala PII, Escala NIP.

ArtigosDual-class unifications and corporate governance in Brazil

Emerging Markets Review, v. 20, pp. 89–108. Abstract: We investigate dual-class unifications in a period following the successful inception of a premium single-class listing segment. Firms that unified increased their market liquidity. Investment opportunities and shareholder rights convergence drove unification of firms that later joined the new premium list. Financial constraints impelled unification firms that remained in the least demanding list. All unified firms that joined the new list remained there five years later. Half of the others delisted or were in serious financial distress. The motivations for unification may differ according to the ability of firms to improve their corporate governance and transparency later.

ArtigosIn search of the Holy Grail: a 20-year systematic review of the happy-productive worker thesis

International Journal of Organizational Analysis, v. 29, n. 5, pp. 1199-1224. Abstract: Purpose: The relationship between job satisfaction and performance is a topic that has been intriguing scholars and managers for a long time. With the flourishing of positive psychology, it has been called the happy-productive worker thesis. New concepts led to new results but still divergent. This study aims to understand the past 20 years of research on the topic, also called the holy grail of the organizational sciences, helping to unwrap conclusions so far. Design/methodology/approach: Bibliometric analysis was performed with R statistical tool’s support, complemented by content analysis, based on studies from three major databases between 1999 and 2019. The empirical studies were analyzed according to the constructs used, shedding light on when the happy-productive worker thesis is more likely to be confirmed. Findings: Results show a variety of constructs and instruments used to operationalize the constructs. This lack of convergence accounts for a large part of the general inconclusiveness of the topic. Indicated research gaps can be useful to both academics and practitioners. Research limitations/implications: Only studies declared as related to the happy-productive worker thesis were considered. Practical implications: Managers can benefit from considering the findings as a basis for decision-making regarding investments in employee happiness at work, focusing on the aspects of happy constructs that lead to productive criteria. Originality/value: The application of mixed methods, complementing the bibliometric with thorough content analysis, provided a more detailed overview of current knowledge about the topic, helping to disentangle different concepts that were treated as similar. Thus, it is possible to understand in which situations happy workers are really more productive.

Keywords: Happiness at work, Productivity, Bibliometrics, Happy-productive worker thesis.

ArtigosInnovation Efficiency in OECD Countries: a Non-parametric Approach

Journal of the Knowledge Economy, v. 12, pp. 1064–1078. Abstract: This study aims to assess the contribution of international trade to efficiency in innovation for members of the OECD. It will do so by adopting a novel analysis on this theme by using Data Envelopment Analysis combined with regressions. The results indicate that being a member of the Asia-Pacific Economic Cooperation is significantly correlated to an increase in efficiency gains while being a member of the European Union does not correlate with the same benefits in this area.

Journal of Business Research, v. 67, n. 4, pp. 567-575. Abstract: This case describes the trajectory of Leblon, a cachaça producer that since its inception regards the world as a market for its product. Founded by entrepreneurs in 2005, the firm’s production process is divided between Brazil and France, and it serves several world markets besides the U.S. and Brazil. The company is a truly born global, and the most striking feature of the firm’s strategy is super premium positioning. The case was developed based on interviews with the CEO and the head of operations, complemented by secondary information. The case is suitable for use in graduate courses that address issues relating to born globals, international entrepreneurship, and international marketing.

ArtigosPandemic and innovation in healthcare: the end-to-end innovation adoption model

BAR −Brazilian Administration Review, v. 18, n. 3. Abstract: The pandemic has been a challenge for many public health systems worldwide. Several health measures and innovations have been implemented to help in reducing COVID-19 spread and to avoid healthcare system overwhelming. During the pandemic emergency, the need for social protection and social distancing scenario has provided the push for healthcare stakeholders to innovate, and telemedicine has emerged as an efficient and effective way to provide care while reducing hospital overload and COVID-19 spread. The pandemic is having a direct impact on innovation and servitization by accelerating innovation processes, creating new interactions among ecosystem actors, promoting new ways to provide value and care, as well as time to market, and social acceptance for innovative solutions. Taking the widespread adoption of telemedicine as an example of innovation processes with the scope to identify which key innovation determinants are participating in the innovation adoption process and what type of contextual conditions are relevant for its development, we propose a seven-stage model with the aim to provide an end-to-end innovation adoption process to map and identify how society, technology, and environment act during the innovation adoption, including economic, social, and political impacts along with its regulation and time to market.

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.

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.

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.

Palavras-chave: Internacionalização de empresas, Born Globals, Comércio eletrônico.

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.

Palavras-chave: Consumidores com deficiência, Textos culturais, Telenovelas brasileiras, Consumidores invisíveis, Decisões de consumo.

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.

Palavras-chave: Estudos de consumo, Consumo de esporte, Adolescentes, Futebol.

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.

Palavras-chave: Inovação, Partial least square, Serviços, Tecnologias móveis.

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.

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.

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.

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.

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.

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.

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.

Palavras-chave: Inovação em serviços. Modelo de Hull e Tidd. Envolvimento simultâneo antecipado. Controle dinâmico de processos.

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.

ArtigosOne decade of evolution of corporate governance practices in Brazil

Revista Brasileira de Finanças, v. 13, n. 1, pp. 134–161. Abstract: This study presents theevolution of certaincorporate governance practices of listed Brazilian companies from 2004 to 2013 gathered in anindex(CGI).Results indicate that the overall quality of these practices improved, notablyafter the  creation of  voluntary  membership  exchange  trading  lists that  require better corporategovernanceand  disclosurepractices. 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.

ArtigosPolíticas governamentais de apoio à internacionalização de empresas brasileiras: um estudo de caso

Gestão e Desenvolvimento, v. 12, n. 2, pp. 179-204. 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.

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.

Keywords: diaspora; internationalization; martial arts; capoeira; Brazilian jiu-jitsu.

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.

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.

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.

Keywords: Investment Funds. Flow. Macroeconomic Factors.

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.

Keywords: Efficiency, Banks, Brazil, Dynamic DEA, Financial distress.

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.

Keywords: Brazil, Bubbles, Ethanol–gasoline price-ratio, Right-tailed ADF tests.

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.

Keywords: Freight traffic, Transport modes, Long memory, Fractional integration, Structural breaks, Brazil.

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.

Keywords: Airlines, Asia, TOPSIS, GLMM-MCMC, Two-stage approaches.

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.

Keywords: Airlines, Africa, TOPSIS, Two-stage, Neural networks, Efficiency ranks.

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.

Advances in Consumer Research, v. 43, pp. 324-328. Abstract: We propose the concept of Longitudinal Rite of Passage as a specific type of ritual that communicates a status transition over time, differentiating itself from more traditional rites of passage by its temporal dimension, since it occurs as a set of multiple and connected behaviors performed throughout consumers’ lifetime.

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.

Keywords: Price unfairness, Price increases, Anger, Service relevance, Service provider dependence.

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.

ArtigosA perspectiva transformativa na análise de significados de produtos de tecnologia assistiva

Revista Economia & Gestão, v. 15, n. 40. Resumo: Alinhada à abordagem da transformative research, a pesquisa objetivou identificar e discutir significados atribuídos à mobilidade urbana e aos produtos de tecnologia assistiva que podem proporcioná-la. A investigação empírica comportou duas etapas: observação participante em oito cidades brasileiras e visita à maior feira de tecnologia assistiva do Brasil. A pesquisa traz resultados pouco explorados pela literatura com foco em consumidores deficientes: apercepção de que produtos de tecnologia assistiva podem ser sacralizados pelos consumidores; e a constatação de que, para certas organizações, vender produtos de tecnologia assistiva torna-se secundário diante da diretriz de construir uma identidade relacionada à cidadania corporativa.

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.

Keywords: Public Policies, Health Impact Assessment, Urban Health.

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.

Keywords: Virtual influencers, Digital marketing, Exploratory study, Artificial intelligence, Robots, Virtualization.

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 significativas, 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.

Keywords: Architecture, Climate change, Energy, Governance, Private sector.

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.

Keywords: Palm oil; Sustainability; Stakeholder perceptions; Local communities; RSPO; Indonesia.

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.

Keywords: Cooking energy, Fuel switching, LPG, Slum, India.

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.

Keywords: Climate governance, Carbon access and allocation, Ethics and equity, North–South, Spatial, Urban–rural.

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.

Keywords: Co-benefit, Life cycle assessment, Wind power, Renewable energy policy, China.

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.

Keywords: Innovation in retail, Innovation in services, Retailing, Service-dominant logic.

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.

Palavras-chave: Compras governamentais, Compras para a inovação, Indução de inovações, Inovação em serviços, Serviços de software.

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.

Keywords: Organizational ambidexterity; Paradox; growth; Exploitation; Exploration.

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.

Keywords: Quality management, Learning capabilities, Knowledge management, Healthcare management.

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.

Keywords: Socially responsible investment, Corporate sustainability, Stock selection, Brazilian mutual 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.

Keywords: Threshold Cointegration, VECM models, Sovereign Risk, Emerging Markets.

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).

Keywords: Sustainable Tourism Competitiveness; Structural Equation Modeling; Formative Construct; Destination Competitiveness; Measurement Model; Brazil.

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.

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. A base de dados foi originada de demonstrativos contábeis de empresas brasileiras do setor econômico de material básico, listadas na Bovespa e na Serasa entre os anos 1994 e 2006 e 2007 e 2012. Os resultados obtidos evidenciaram a alteração de algumas variáveis selecionadas para a caracterização daquelas empresas que se tornaram descontínuas. Empresas do setor de material básico, no período estudado, 2007 a 2012, que se adequaram às exigências do mercado, privilegiando a liquidez em detrimento ao operacional, lograram sucesso em sua continuidade.Palavras-chave: Descontinuidade de empresas.

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.

Keywords: Risk governance, Public participation, Japan, Earthquake, Tsunami, Local knowledge.

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.

Keywords: Urban energy system, Optimization modeling, Cost-effective, Electricity deficiency, Co-benefits, Delhi.

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.

Keywords: GARCH and EGARCH models, Realized volatility, Realized range.

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.

Keywords: Sport celebrity, Source credibility, Endorsement, Sport Involvement.

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.

Keywords: Autonomy, Brazil, Phenomenography, Qualitative research, Skilled workers.

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.

Keywords: Board characteristics, Executive compensation, Corporate governance, Ownership concentration, Brazil.

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.

Keywords: fuzzy logic; inventory management; production sequencing; systems engineering; cosmetics manufacturing; Brazil.

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.

Keywords: Information Security; Safe Behavior; Users’ behavior; Brazilian users; threats.

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.

Keywords: Islamic banks, TOPSIS, Two-stage, Neural networks, Efficiency.

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.

Keywords: Academic performance, Predict, tertiary students, logistic regression.

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.

Keywords: Virality; Marketing Innovation; Innovative Marketing Strategies; Viral Video Content; Structural Equation Modeling.

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.

Keywords: Knowledge management, hybrid organisations, quasi-governmental organisations, Brazil.

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.

Keywords: China, Seaports, stochastic frontier, efficiency, port policy.
