International Journal of Disclosure and Governance v. 20, pp.261–273. Abstract: This study analyzes the relation between firm performance and top management team turnover, moderated by corporate governance and control variables. We use a unique dataset of CEO and executive turnover of Brazilian firms from 2010 to 2017, including companies that voluntarily adopt good governance practices through listing on “Novo Mercado” segment. We document a significant growth in top management turnover activity throughout the sample period and find a negative relation between firm performance and CEO turnover. We also document that family firms listed in the “Novo Mercado” segment have greater CEO turnover performance sensitivity than family firms not listed in “Novo Mercado.”

Keywords: CEO turnover, Firm performance, Corporate governance.

BASE – Revista de Administração e Contabilidade da Unisinos, v. 20, n. 2. Abstract: This study investigates the contribution of well-known multifactor asset pricing models to estimate the cost of equity capital of Brazilian listed companies with the Capital Asset Pricing Model (CAPM), the three-factor model of Fama and French (1993), the Carhart (1997) four-factor model and a five-factor model that consists of an additional illiquidity risk factor. The sample are the returns of individual stocks comprising a portfolio of companies in the IBrX 100 stock index from July 2008 to June 2018. Distributions of individual company cost of equity capital estimates obtained with each model were compared among themselves in the full sample period and two sub-periods. The results suggest that adding extra risk factors to the CAPM does not always translate into different cost of equity capital estimates and significantly greater explanatory power. The practical implication is that the CAPM estimates may often be the same as those obtained by means of more complex models with the added bonus of the CAPM’s simplicity.

Keywords: Cost of equity capital, Multifactor models, Brazilian listed companies.

Marketing & Tourism Review, v. 7, n. 1. Abstract: Perceptions of risk are not always in line with objective risk measures. According to the decision-making literature, this is due to affective evaluations laypeople do over hazards instead of a more deliberative judgement. Against this backdrop, this study investigates tourists’ perceptions of risk in relation to the most affected countries by COVID-19, and compare it to their objective risk measures. Our findings suggest that people think in accordance with the denominator neglect effect while assessing risk of contamination, that is,they consider  the  total  number  of  infected  peopleand  disregard  its  proportion  inrelation  tothe  population.  Also, news media consumption was found to be associated with distinguishing low-risk of contamination countries, but not top risky ones. These results shed light onbiases in people’s judgements that need to be taken into accountby tourism anagers, as the sector begins its recovery.

Keywords: Risk perception, COVID-19 pandemic, tourist behavior.

Revista FSA, v. 20, n. 8. Resumo: O objetivo deste estudo é identificar de que forma um comunicado corporativo pode afetar o ambiente de negócios de uma empresa, levando-a a uma posição de extrema fragilidade. Para alcançar esse objetivo, foram utilizadas três metodologias distintas: pesquisa bibliográfica, levantamento documental e análise de dados. Os resultados obtidos sugerem que a falta de padronização no tratamento das operações mencionadas no comunicado das Americanas causou ruído informacional. Além disso, o fato de o próprio comunicado ter sido pouco preciso ampliou o ruído, com severo impacto no mercado. Em particular, após o fato relevante, foi observada uma forte reação no mercado bancário e varejista, produzindo perdas para acionistas minoritários e credores, não apenas para a Americanas, mas também para outras empresas do setor. Assim, ficou evidente que a forma como os problemas corporativos são comunicados em setores suscetíveis a crises, corridas e contágio pode fazer uma diferença significativa.

International Journal of Sports Marketing and Sponsorship, Vol. ahead-of-print No. ahead-of-print. Abstract Purpose: Despite to useful relevance to better understand how group-level identity develops, few studies have explored the identity theory in the esports field and, in particular, considering the impact of a fan’s role identity. The current study aims to explore esports fan role-identity vis-à-vis the relationship with the sponsor and the sponsee so as to understand the effects on their behavioral intentions. Design/methodology/approach: Using a sample of 356 esports fans who attended the 2021 FPF eFootball Open Challenge, a Confirmatory Factor Analysis (CFA) analyzed the psychometric properties of the constructs and a subsequent Structural Equation Modeling (SEM) examined the effects of fan identity on two types of behavioral intentions and sponsor–sponsee relationship. Findings: Results indicate that fans who highly identify with esports have the highest attachment to the event and tend toward having a positive word-of-mouth intention. Esports fans who have a higher brand identification reported a positive attitude toward the event’s sponsor brand and tend to purchase its products. Moreover, the study findings also provide evidence of the bidirectional interaction between the way in which fans attach with the esports event and its sponsor brand, leading to greater reciprocity in their identity formation. Originality/value: This study helps to understand how the fan identity process can enhance its fate and develop mutually, building role overlapping identity in the esports sponsor–sponsee relationship. Complementarily, it supports of how the marketeers and managers must analyze the importance of being a fan to the individual in order to understand how its self-identity can shape the future behavior.

Keywords: Fan identity. Identity theory. Brand identity. Behavioral intentions. Esports.

Simulation & Gaming, Volume  Ahead of Print. Abstract Background: Due to the social nature of esports (i.e., organized video game competitions), recognizing common values and norms can be leveraged as a positive driver in online gaming communities. Different game categories such as sports simulation (i.e., esports based on real-life sport events) are driving their expansion through social interactions that foster new relationships among players, known as social capital (i.e., value created from social connections, relationships, and networks within the gaming community). Despite recent studies showing the social role of esports (e.g., on satisfaction, loyalty, or well-being), little empirically derived insight exists regarding its sport values, social capital formation and positive word-of-mouth in different gamer communities on the Internet. Aim: This study aims to achieve two objectives: (a) to examine how sports values (excellence, friendship and respect) influence the in-game social capital formation (bridging and bonding) and word-of-mouth intention by the esports players; and (b) to determine whether differences occur according to sports simulation and non-simulation games. Method: Data were collected among esports players (n = 509), and the results were analyzed using structural equation modeling to test hypothesized relationships between the constructs and multigroup analysis to verify if the path coefficients differ among both game groups. Results: Friendship value was the strongest predictor of bonding and bridging capital formation in both groups. The excellence value showed a positive effect on strong social ties created towards non-simulation games, while playing well or reaching high in-game performance did not contribute to creating bonding capital in sports simulation games. Both bonding and bridging capital were strong predictors of behavioral intentions. Conclusion: Social implications focus on cultivating the sportive values and enhancing social ties on player community as a way to share good experiences or to talk positively about the game. Esports industry should consider the well-established and mediating construct of social capital, strengthening in-game bonding, and bridging relations as a broader theoretical basis.

International Journal of Health Planning and Management, v. 38, n. 5, pp. 1250-1267. Abstract: Service Design (SD) represents a breakthrough in searching for solutions to health systems challenges, but the activities that support these solutions remain underexplored. This research investigates how SD has been applied in the healthcare sector based on two conceptual models: multilevel ecosystem perspective and SD transformative approach. First, we conducted a systematic literature review in eight comprehensive databases in March 2021. Eligibility criteria returned 990 articles filtered by a search protocol, resulting in 47 studies. After this, we identified 23 studies (49%) with a transformative approach through a thematic analysis. Also, the analysis of these 23 studies allowed the identification of five key aspects necessary for enabling a transformative character of SD initiatives: (1) identification of all the actors that make up the provision of healthcare services, (2) identification of users by ecosystem level, (3) knowledge about the SD tools arsenal, (4) use of technology, and (5) applying the Experience-Based Design and Co-Design (EBD/EBCD) approach. The study underlines the role of management for the success of SD in the health sector and suggests an instrument (checklist) to help managers implement SD initiatives successfully.

Research in Transportation Business & Management, v. 46. Abstract: This study aims to present a probabilistic evaluation of the eco-efficiency performance of truck transport, considering the implementation of improvements in technology and public and private management, which can help reduce fuel consumption, accidents, and emissions of CO₂. We applied the Monte Carlo simulation to verify the possible performance levels achievable via the proposed actions. The results show that the roadway mode slightly improved its performance, when compared with nine intermodal alternatives, rising from last place to eighth place for transport of ethanol. Thus, the research points to two approaches that should be the agenda of a national transport policy: (1) intermodal transport alternatives remain the best options for transporting ethanol and it should be encouraged; (2) actions to reduce CO₂ emissions by applying better technology and actions by public officials to reduce the number of accidents have the greatest impact on the likelihood of improving the performance of trucking.

Management International Review, v. 63, pp. 673–696. Abstract: This study aimed at investigating the interplay between internationalization and digitalization using a social media platform during the early phases of the internationalization process of new ventures from an emerging economy. The research adopted the longitudinal multiple-case study method of investigation. All the firms that were studied had operated on a social media platform (Instagram) since their inception. Data collection was based on two rounds of in-depth interviews and secondary data. The research used thematic analysis, cross-case comparison and pattern-matching logic. The study contributes to the extant literature by (a) proposing a conceptualization of the interplay between digitalization and internationalization during the early phases of the internationalization trajectory of small new ventures from an emerging economy using a social media platform; (b) detailing the role of the diaspora during the outward internationalization of these ventures and outlining the theoretical implications of this phenomenon; and (c) providing a micro perspective on how entrepreneurs exploit platform resources and face platform-related risks during their enterprise’s early domestic and international phases.

Keywords: Internationalization, Digitalization, Social media, Small firm, Emerging economy.

The Quarterly Review of Economics and Finance, v. 91, pp. 84-93. Abstract: This article analyzes the role of access to digital and physical forms of finance on income inequality. The article develops a new measure of financial access that captures the relationship between digital finance and inequality, using a dynamic panel data analysis on 116 countries between 2001 and 2019. The results indicate that access to both financial institutions and digital access may reduce inequality, suggesting that they are complementary. We also find evidence suggesting that, in emerging economies, access to digital financial is more relevant than physical access.

The CASE Journal, v. 19, n. 4, pp. 599-613. Abstract Research methodology: This teaching case was based on both primary and secondary sources of information. An interview with the entrepreneur and protagonist of the case was conducted, recorded and fully transcribed. Also, secondary data (digital and print media) were obtained from the interviewee, before, during and after the interview, as well as on governmental, institutional and company websites. Case overview/synopsis: The Ninho da Águia Farm is a family business located in Minas Gerais and specialized in coffee production. Although founded in 1969 by Aides Gomes Monteiro, it was only when his surfer son Clayton Barbosa Monteiro took over the business that the small farm started focusing on specialty coffee, quality beans and international markets. With no formal education, Clayton managed to implement several managerial, organizational and strategic changes in the company, including its internationalization. Understanding the logic behind the development of the farm can help students understand several important concepts in International Business in relation to international entrepreneurs and effectuation/causation decision-making logics. Complexity academic level: This teaching case was designed for graduate courses in international business/international strategy. But because of the richness of the case, it could also be used in other courses (e.g. marketing or international marketing). However, should this be the case, different teaching notes would be necessary.

Keywords: Entrepreneurship, Teaching case, Effectuation, Internationalization, Agribusiness.

dObra[s] – Revista da Associação Brasileira de Estudos de Pesquisas em Moda, n. 37, pp. 14–30. Resumo: Este estudo busca entender como se constituem as relações sociomateriais entre humanos e não humanos para além da dialogicidade, ou seja, a relação entre o consumidor e um objeto de consumo específico. Para isso, baseia-se na abordagem das Ontologias orientadas a objetos (HARMAN, 2018), considerando os armários como unidades centrais na composição de assemblages, que reúnem diversos objetos em relação entre si. O percurso metodológico construído visou à experiência centrada em objetos, observando como a sociomaterialidade em ação opera de maneiras distintas a partir dessas interações coletivas. A partir da análise de armários como uma assemblage de consumo (CANNIFORD e BAJDE, 2016), o trabalho evidencia um arcabouço conceitual alternativo capaz de oferecer aos estudos de moda novos recursos teóricos para se entender a relação entre diversos objetos.

Journal of Consumer Behaviour, v. 22, n. 5, pp. 1199-1210. Abstract: Previous research implies that the transformational potential of extraordinary experiences arises from the engagement with the experiential context, although we still do not know how this process happens and to what extent it changes consumers. In this article, we explore the processes by which consumers transform themselves through extraordinary experiences and the characteristics of such a transformation. Based on a three-year ethnography in the context of marathon running, we identified the three processes that engender consumer transformation: the physical transformation process, the mental transformation process, and the discursive transformation process. These processes are sheltered by the transformational escape, defined as the consumption setting that integrates structural and antistructural features through the engagement of consumers’ routine with the extraordinary experience, enabling consumer transformation. We extend current theorizations by revealing the dynamics that elongate extraordinary experience duration, enable the dynamic between routine and extraordinary experience, and enlarge the reach of consumer transformation.

Qualitative Research in Organizations and Management, v. 18, n. 2, pp. 181-198. Abstract Purpose: In a context where human–machine interaction is growing, understanding the limits between automated and human-based methods may leverage qualitative research. This paper aims to compare human and machine analyses, highlighting the challenges and opportunities of both approaches. Design/methodology/approach: This study applied qualitative secondary analysis (QSA) with machine learning-based text mining on qualitative data from 25 interviews previously analyzed with traditional qualitative content analysis. Findings: By analyzing both techniques’ strengths and weaknesses, this study complements the results from the original research work. The previous human model failed to point to a particular aspect of the case, while the machine analysis did not recognize the sequence of time in the interviewee’s discourse. Originality/value: This study demonstrates that combining content analysis with text mining techniques improves the quality of the research output. Researchers may, therefore, better handle biases from humans and machines in traditional qualitative and quantitative research.

Keywords: Content analysis; Text mining; Qualitative secondary analysis.

BIB – Revista Brasileira De Informação Bibliográfica Em Ciências Sociais, v. 1, n. 98, pp. 1–24. Resumo: Neste artigo, avaliamos a internacionalização da produção científica docente dos PPG notas 5, 6 e 7 dentro da área Ciência Política e Relações Internacionais, no período 2011-2020. Foi utilizada a base de dados SciVal, que possui ferramentas e indicadores de produção científica, que, tendo como fonte de dados o Scopus e o Science Direct, permite análises bibliométricas comparativas por instituição, país, região, autor ou grupos de autores. O estudo concentrou-se em avaliar dois indicadores (a) Colaborações internacionais, que contabiliza o número e percentual de publicações produzidas em coautoria internacional, e (b) Percentagem de internacionalização, baseado na identificação dos principais países para colaborações estrangeiras. Interpretamos estes dados à luz da Global International Relations (Global IR), corrente teórica que têm debatido os desafios da disseminação da ciência produzida no Sul global. Os resultados apontam que, mesmo em programas consolidados, a internacionalização varia consideravelmente, havendo predomínio dos Estados Unidos e Europa como parceiros. A internacionalização permanece estruturada no docente, sendo, portanto, pouco institucionalizada.

Sustainable Production and Consumption, v. 40, pp. 89-100. Abstract: Motivated by the changes in the understanding and the growing importance of sustainability engagement among companies, investors, and societies, this paper has for objective to understand how a multinational corporation adjusts its sustainability engagement to different cultures, institutions, and market realities as this topic becomes imperative through the triad Environment, Social, and Governance (ESG) responsibilities. To that end, a qualitative case study of The Coca-Cola Company was used as the basis for this research. The methodology chosen supported the analysis of a situation where an international company operating in different markets must implement a balanced approach in order to fulfill its asymmetries. One important finding was that ESG implementation depends on local resources, which may lead to further asymmetries instead of increased global balance. Another result presented is a model that helps identify essential corporate sustainability issues for defining the strategies, targets, and plans for global, local, and individual levels that may be used by researchers and practitioners alike. This model shall be refined and improved by future research with other organizations that operate globally and must adjust their corporate sustainability strategy according to the United Nations’ Sustainable Development Goals while using local implementation strategies aligned with the national institutional realities of the different countries.

Journal of Family Business Management, v. 13, n. 1, pp. 210-225. Abstract Purpose: The present study used a process approach to examine how a small entrepreneurial family business in the tourism industry evolved during different stages of the Covid-19 pandemic and across different dimensions of resilience. Design/methodology/approach: The research strategy consisted of a real-time longitudinal case study during the Covid-19 pandemic in Brazil, based on interviews conducted with the founders of the business. Findings: The results show how the firm responded to the pandemic and moved through different stages – interruption, loss, resumption, and recovery – as the crisis evolved. During each stage, there were manifestations of different dimensions of organizational resilience: anticipation/awareness, coping and adaptation. The entrepreneurs mobilized several capabilities – emotional, cognitive, behavioral, and relational – during the different stages and across different dimensions to face and respond to the pandemic. Originality/value: The contributions of the study stem from the lack of research on how small entrepreneurial family businesses in the tourism industry are impacted by disruptive events of long duration and multiple cycles. Specifically, the study contributes to the understanding of how this type of firm responds to these crises, mobilizing different capabilities at different stages and across different dimensions of organizational resilience.

Internext, v. 18, n. 1. Resumo: Objetivo: Examinar como uma empresa proveniente de um país emergente adota estratégias específicas para neutralizar os passivos de origem estrangeira (LOF), emergência (LOE) e não pertinência a redes (LOO) e para ganhar legitimidade em um ambiente institucional de alta qualidade. Método: Estudo de caso único, em profundidade, de uma empresa brasileira do setor de tecnologia da informação, com base em dados secundários e entrevistas. Principais Resultados: O estudo mostra como a aquisição de uma empresa local lidou com os três passivos: LOF, adquirindo conhecimento sobre a estrutura institucional do ambiente do país de destino; LOE, ao desvincular a imagem da empresa do país de origem e enfatizar uma imagem global; e LOO, obtendo acesso a conexões já estabelecidas em redes internacionais pela empresa adquirida. Relevância/ Originalidade: Ainda há uma escassez de literatura sobre como as empresas de outros países emergentes, além da China — e particularmente da América Latina —, adotam estratégias para atenuar LOF, LOE e LOO ao se internacionalizarem para ambientes institucionais de alta qualidade. Contribuições Teóricas/ Metodológicas: Fornecer uma visão aprofundada da relação entre LOF, LOE e LOO e suas manifestações; e proporcionar uma compreensão da relação entre os passivos enfrentados e as estratégias de legitimação adotadas para superá-los ao longo da expansão internacional de uma empresa de alta tecnologia proveniente de uma economia emergente da América Latina.

International Journal of Oil, Gas and Coal Technology, v. 32, n. 4. Abstract: Many stakeholders are involved in liquefied petroleum gas (LPG) after-sales service. Using soft computing, we rank the after-sales service of Iranian LPG companies in terms of global competitors’ best practices, comparing four global companies that offer after-sales services as benchmarks. Fuzzy importance and performance analysis (FIPA) was used to identify customary after-sales performance indicators. Then, we used step-wise weight assessment ratio analysis (SWARA) to determine their relative weights. Using fuzzy complex proportional assessment (FCOPRAS), we ranked the top 12 Iranian LPG companies in terms of market share. FIPA, SWARA, and FCOPRAS are combined in this paper for the first time to identify the most important factors for ranking LPG companies in the world-class after-sales services category.

Keywords: after-sales service, fuzzy MCDM, grey relational analysis, GRA, LPG industry.

Transportation Planning and Technology, Vol. ahead-of-print No. ahead-of-print. Abstract: The paper analyzes the sustainability of the Chinese transportation sector by examining the relationship between energy consumption (and CO2 emissions), transportation modes, and macroeconomic variables. Principal Component Analysis (PCA) and Neural Networks (NN) are combined using monthly data from January 1999 to December 2017. Our goal is to propose a model that links China’s transportation footprint to major macroeconomic factors while simultaneously controlling each mode of transportation. Inflation and credit policies exert relatively weak effects on the explained variable. In contrast, trade and fixed asset investments, as well as monetary and fiscal policies, show a positive and significant impact. The use of waterways and airways plays an imperative role in sustainable development compared to the use of roads.

Keywords: China; transportation modes; sustainability; macro-economic variables; principal component analysis; neural networks.

Revista de Administração Comtemporânea, Vol. ahead-of-print No. ahead-of-print. Abstract: The case shows the difficulties faced by a social business to become financially viable. Talita Peixoto is an African-Brazilian woman enterprising for the first time. Together with her husband, she created Clubinho Preto, a Brazilian subscription club for children that delivered boxes with books, clothing, and accessories to educate children in a positive Afrocentric culture. After two years, they are struggling financially. Looking for alternatives, Talita planned to expand her business by adding schools as clients. Her business partners opposed the idea, believing that not every manager would truly commit to the racial cause. Talita needed the money, but not at any cost. How can she transform her purpose into a product? To answer this question, it is necessary to align purpose, value creation, and a business model. This case can be taught in executive training programs and undergraduate classes on marketing and consumer behavior, social entrepreneurship, and business purposes. We invite teachers and students to include the discussion on diversity, equity, and inclusion in all these disciplines.

Keywords: marketing, purpose, DE&I, social entrepreneurship, positive Afrocentric culture.

Consumption Markets & Culture, v. 26, n. 5, pp. 361-376. Abstract: This research investigates how heroic failure narratives displayed by a social media influencer are received and signified by online audiences. Based on a netnography, we analyse the journey of a marathonist and social media influencer in his unsuccessful quest to qualify for the Boston Marathon. Our analysis reveals how failure in a heroic quest triggers narratives and meanings related to a humanized heroic archetype. We delineate the concept of heroic failure narratives as those that, despite the failure to perform, perpetuate a prominent and special condition of the protagonist, conveying authenticity, building engagement and humanizing the relationship with the audience. We depict three heroic failure narratives, their meanings and functions: (1) Failure as a heroic process; (2) Failure as an affective bond; and (3) Failure as a tragic human fate. We discuss how heroic failure narratives may affect admired public figures, online audiences, brands, and society at large.

Keywords: Failure; hero; myth; archetype; online audience; social media influencer.

Journal of Business and Psychology, Vol. ahead-of-print No. ahead-of-print. Abstract: Research has shown that leader-member exchange (LMX) differentiation leads to specific patterns of LMX quality within a team. These patterns are typically assessed through multiple properties that have different consequences for individuals and teams. Although a more comprehensive and nuanced understanding of the consequences of LMX differentiation can be achieved by incorporating these properties in a single framework, studies of this nature have been scarce. Drawing on the social comparison perspective and distributive justice principles, this study proposes a multilevel model to examine the motivational mechanisms through which two distinct properties that arise from the LMX differentiation process — LMX variation and LMX relative position — simultaneously affect individual and team performance. We also examine the cross-level moderating effect of LMX variation. Using a multilevel, multisource, and multiwave research design, we collected data from 1098 healthcare professionals nested in 95 teams in 27 emergency care units and from more than 3000 patients to explore the effects of LMX differentiation on individual and team performance outcomes. The results revealed that, at the individual level, LMX relative position was positively associated with individual performance via employees’ psychological empowerment. At the team level, however, LMX variation showed a negative indirect effect on team performance via collective efficacy. Theoretical and practical implications of our findings for teams and organizations are discussed.

Journal of Consumer Behaviour, v. 22, n. 4, pp. 785-800. Abstract: This article contributes to different research traditions when proposes to reflect on theoretical fields, such as consumer culture and contemporary marketing. The study in a tourist and ecological conservation project revealed eco-restricted extraordinary experiences. We found a group of volunteers that build meanings and practices connected with new actions and habits that offer, not only ecological and sustainable benefits, but new value consumption relations. In contextualizing our findings, we highlight experiences and curiosities that are glossed over in academic and practical accounts that celebrate the extraordinary experience. It was observed, by analyzing data from various qualitative techniques, that the findings cross borders of mundane ingrained practices and bring an emerging domain, where both, consumption and anti-consumption experiences, offer insights into to a diversity of areas of knowledge.

JAIS Preprints, Vol. ahead-of-print No. ahead-of-print. Abstract: While most studies on digital financial inclusion highlight its positive aspects, we focus on the surveillance phenomenon by investigating the role played by microcredit agents who operate digital financial platforms. We combine the concepts of surveillance capitalism and platform capitalism within the digital financial inclusion process and propose a surveilled inclusion model that considers the role of human agents interacting with clients to expand the network effects and control of the digital platform in a dialectic interplay. We combine instrumental/in-depth case study and critical hermeneutics as methodological strategies to produce results that help to uncover the hidden agenda of social fintech organizations that use digital platforms to provide microcredit. In addition, we expand Zuboff’s concept of surveillance capitalism by including the role of microcredit agents who reinforce the imprisonment of clients in endless cycles of payment and credit renewal.

Borsa Istanbul Review, v. 23, n. 3, pp. 736-747. Abstract: Concerns regarding social and environmental issues have become a pervasive aspect of economic relationships, prompting banks’ role in social-environmental sustainability to occupy a growing share in the economic debate. Nevertheless, what is the relationship between bank behavior and sustainable activities? This paper presents the relationship between the disclosure of social-environmental policies and bank risk tolerance using a newly developed Social-Environmental Transparency Index for financial institutions. Using a dynamic panel database analysis of the 42 largest Brazilian banks, which represent about 98 percent of the Brazilian financial system, we estimate the impact of risk-taking by banks on their social and environmental transparency. The results indicate that safer banks have greater social-environmental transparency, and banking social and environmental regulation is important in increasing the sector’s transparency. Finally, social-environmental disclosure has a persistent effect. Thus, transparent banks tend to be more transparent over time.

Sustainability, v. 15, n. 11, 8517. Abstract: This study analyzes the financial performance of sustainable investments against conventional investment products in an emerging market context using a sample of sustainable and governance equity investment funds that focus solely on the Brazilian stock market. A quantitative analysis is used to compare monthly returns, volatility, and Jensen’s alpha for the period of January 2017 to December 2019 (bull market) and January 2020 and December 2021 (bear market). The study finds that sustainable investments do not diverge from conventional stock funds during a bear market period in terms of financial performance and present similar volatility. The main findings of this study corroborate the latest research from the ANBIMA reports related to sustainability practices in the Brazilian capital markets. The study also contributes to the academic literature by providing empirical evidence from an emerging economy such as Brazil of reasonable performance from sustainable investments in different periods of an economic cycle. The study has a few limitations such as the lack of a taxonomy and an ESG regulatory framework for the sustainable and governance equity investment funds and the small number of sustainable and governance equity investment funds in Brazil.

Keywords: ESG; sustainable investments; sustainable finance; financial performance; equity investment funds.

Socio-Economic Planning Sciences, v. 87, Part A. Abstract: Previous road transportation sustainability studies not only neglected the epistemic uncertainty that surrounds the impact of innovation and Research and Development (R&D) expenditure on pollutant emissions performance but also failed in designing and simultaneously exploring the strengths of alternative MCDM (Multiple-Criteria Decision-Making) approaches to better discriminate performance scores. This paper focuses on these two gaps by presenting a road transportation sustainability performance assessment of 29 Chinese provinces for a 14-year period in light of relevant socioeconomic and demographic variables. First, a novel TEA-IS model is developed to assess road transportation sustainability performance. Besides possessing the beneficial features of each model, this hybrid DEA-TOPSIS can analyze the sustainability performance from the perspective of the synergistic effects among the criteria. From the socioeconomic and demographic perspectives, we use machine learning techniques for predicting high-low performance and synergistic Chinese provinces. Results suggest that the discriminatory power of TEA-IS is good and there is high synergy in Chinese provinces in terms of sustainable road transportation. We further find that there is a high level of heterogeneity in road transportation sustainability among different geographical locations in China. The results further suggest that higher levels of synergy are strongly associated with medium and high-performing provinces. Finally, we find that innovation index, foreign direct investment, and non-coastal cities have both higher performance and synergy levels. We recommend that Chinese government should further provide favorable policies to enhance innovation and efforts should also be made to provide better environment for attracting more foreign direct investment. Finally, instead of road transportation, other modes of transportation, such as air and sea, are recommended to be further developed and utilized.

Keywords: China; Road transportation; Sustainability; Performance and synergy; Hybrid DEA-TOPSIS; TEA-IS.

Operations Research Perspectives, v. 10. Abstract: This paper investigates the social-welfare efficiency drivers of public university hospitals in Brazil by focusing on how the surrounding social welfare conditions may affect their performance. A novel Genetic Envelopment Analysis (GEA) approach is developed here to this end. Subsequently, LASSO regression is applied to filter the impact of social-welfare related variables –on efficiency scores. Results indicate that beds, number of employees and number of doctors are the influential factors in determining the efficiency level, while the operating scales are not relevant to the productivity level. We further find that there is a degree of difference related to the efficiency level among the hospitals in the sample. Finally, our results show that GEA estimates present higher discrimination and dispersion compared to DEA, SFA and TOPSIS, also GEA provides the most reliable and accurate results. In the second stage analysis, we find that female population ratio and high school ratio significantly affect the efficiency level in a negative manner, while the urban population ratio has a significant and positive impact. Based on these results, we provide important policy implications.

Modern Economy, v. 14, n. 5. Abstract: In 2023, the global economy is going through a number of challenges. The imposition of sanctions on Russia, as a result of the Ukraine-Russia conflict, has unleashed and fostered a new globalization cycle and paradigm, with important implications for global business. This paper explores one of the consequences of this new globalization paradigm that is unfolding—the expansion of the BRIC group, “BRIC Plus”, and its challenges and opportunities. The increasing fragmentation of the established globalization paradigm and the new geopolitical and geoeconomic global realignment will send shockwaves throughout the global economy. The looming global recession may aggravate these outcomes.

Keywords: BRICS Plus; Global Economy; Inflection Point.

RAUSP Management Journal, v. 58, n. 1, pp. 39-54. Abstract Purpose: This study aims to contribute to routine dynamics literature and organization process practices. The main objective is to identify different ways organizational members (re)construct truces at the boundaries of budgeting routines where (re)plannings face scarce resources and, consequently, require modifications in routines. Design/methodology/approach: The research adopted the phenomenographic theoretical-methodological approach to investigate from a process perspective. Twenty-two professionals from 17 companies were interviewed about their experiences with budgeting. Three conceptions and six explanatory dimensions were organized systematically on a conceptual map, which provided insights for three new propositions. Findings: Three conceptions about truce (re)construction were found: “authority subjection” denotes an obedient behavior toward centralized orders for budget cuttings; “prudent assimilation” explains how some specific routines are preserved from resource reduction; and “participatory interactions” stand for exhaustive and participative efforts for negotiations beyond routine frontiers. Three theoretical propositions are also presented: “awareness of systemic complexity” may strengthen arguments for negotiations; “team’s collective configuration of relationship networks” reinforces collective attributes; and “social-based learning” may be developed through truce (re)construction. Research limitations/implications: Jorgüen Sandberg, who brought the phenomenographic approach to Organization Studies in 2000, stances that it is not assured that conceptions cover all varied forms of the phenomenon. Practical implications: Implementing these findings in organizations may improve commitment to ecology of routines and decentralized decisions with a sense of responsibility for financial plans. Social implications: This study encourages transparency and ideas for cost-efficient resource use. Originality/value: This study provides advance knowledge about truce in routines while encompassing its ecology.

Keywords: Organizational routines; Truce; Interdependencies; Budgeting; Process perspective; Procedural perspective.

Expert Systems with Applications, v. 225. Abstract: Despite the turmoil in the global financial sector over the years, Asian banking stood still with many positive characteristics – stable, balanced competition, good governance, and profitable – becoming a fertile ground for performance studies. This paper departs from previous banking performance studies in Asia by proposing a novel stochastic Multi-Criteria Decision-Making (MCDM) based on sign decomposition, offering a novel perspective in five analytical fronts. First, criteria decorrelation and filtering from country and time impacts as an initial data treatment. Second, endogenous computation of bank criteria importance for the alternatives comprised by each bank and year under analysis, in a “one-stop-shop” approach. Third, derivation of partial performance scores for each criterion under each alternative, besides traditional overall performance scores for each alternative. Fourth, mapping the exogenous/endogenous relationships among bank filtered criteria from country and year impacts using transfer entropy. Fifth, prediction of the overall performance drivers in terms of country-related contextual variables using neural networks. Our findings indicate that bank liquidity, bank capitalization, net income as well as the ability to generate profit for the shareholders are significantly related to bank performance. In addition, we find that accounting standards have a significant impact on bank performance. Although inflation is found to be positively related to bank performance, the results show that bank performance is helpful to promote people’s economic standard and life expectancy. Our study provides important implications to macroeconomic management to balance the development of macroeconomic development and bank performance.

Keywords: Asia, Bank performance, MCDM, Sign decomposition, Transfer entropy, Stochastic analysis.

Environment Systems and Decisions, v. 43, pp. 321-336. Abstract: Driven by improvements in the understanding and the growing importance of sustainability engagement among individuals and companies, this study aims to analyze the sustainable development of a renowned Consumer Goods Company. Natura &Co is a Brazilian multinational that forms among the five largest global beauty corporations, owning four major brands—Avon, The Body Shop, Aesop, and Natura. This study used a case study methodology and had the objective of analyzing the strategies adopted by the company through time while engaging in the global sustainability agenda. It also covers a gap in the literature in analyzing Latin American multinationals. The company is assessed through a case summarized into a sustainability motivations framework of four quadrants, namely social insurance, market success, legitimacy, and process improvement. As one of the main findings, the case confirms literature indications of the evolution of sustainability motivations and strategies from simple compliance with the law and social rules into innovation and differentiation, which allowed the company to compete globally.

International Journal of Sports Marketing and Sponsorship, Vol. ahead-of-print No. ahead-of-print. Abstract: Purpose: Despite the advances in theory and practice about player behaviour in esports gaming literature, there is a lack of understanding as to whether esports are compatible with the values of Olympism and if they should be considered for future Games editions. The current study advances this line of research by examining esports player experiences, their effects on perceiving Olympic values, and the support towards the Olympics in order to verify if differences occur according to the cross-cultural environment. Design/methodology/approach: Using a sample of 671 esports amateur gamers from three countries (Portugal, Brazil and Japan), structural equation models and a multigroup analysis were performed to analyse the differences in the hypothesized paths existing between the groups. Findings: Results reveal that player in-game emotional experiences positively influence Olympic values perception across countries. The excellence and friendship values showed a positive effect on support intentions to the Games towards Portuguese and Brazilian players, while the respect value was the strongest predictor towards behavioural intentions in Japan. Cultural backgrounds and game genre in each country can explain player attitude towards the Olympic values shared on the online environment. Originality/value: This study is able to provide a better understanding of how the Olympic values serve as a gratification in different cross-cultural environments according to the theory of uses and gratifications (U&G) and the theory of cultural dimensions. Complementarily, these findings can be used as valuable information for esports publishers and developers attempting to spread the Olympic values in the esports industry.

Keywords: Emotional experience, Olympic values, Behavior support, Portugal, Brazil, Japan.

Technological Forecasting and Social Change, v. 193. Abstract: Technology affordances democratize access to entrepreneurship, making it relatively common for consumers to expand their social media activities to become digital entrepreneurs. The decreasing distance between consumption and entrepreneurial practices on digital platforms such as Twitch, Spotify, and YouTube amplifies the influence of cultural elements germane to entrepreneurial ecosystems. This article investigates the effect of this societal change on the discourse and behavior of consumers through the lens of institutional logics theory. It uses computational social science methods to analyze 1,909,370 comments posted on 249 videos published on a YouTube channel that unboxes technological products. The findings show that many end-users offer business advice to digital influencers as if they are collaborating with a buddy entrepreneur. A quantitative procedure demonstrates that these individuals have more subscribers than the average end-user. Further, the percentage of comments on this interaction correlates positively with end-user (consumer) engagement. This relationship indicates that a digital influencer’s ability to inspire entrepreneurial behavior among end-users may benefit his/her business. It also suggests the existence of an entrepreneurship-related continuum from consumers to digital influencers.

Keywords: Entrepreneurial ecosystem, Consumer behavior, Institutional logics, Digital platform, Computational social science.

The International Journal of Accounting, v. 58, n. 2. Abstract: Research problem: We investigate whether accountants’ cognitive reflection ability affects how they assess the probabilistic numerical thresholds of the probabilistic expressions probable, remote, virtually certain, and reasonable certainty in the context of international financial reporting standards. Theoretical reasoning: In the psychology literature, impulsivity is associated with aggressive behavior, and reflective individuals are more prone than impulsive individuals to access slow and effortful (Type 2) reasoning in order to overcome the initial response provided by fast and impulsive (Type 1) reasoning. Considering that accounting conservatism requires a higher degree of verification to recognize events that increase rather than decrease net assets, we argue that impulsivity is associated with aggressive accounting and reflectivity is associated with a conservative interpretation of probabilistic expressions. Test hypothesis: Reflective accountants are more conservative than their impulsive peers when making numerical assessments of probabilistic expressions associated with accruing or disclosing an event. Target population: Accounting professionals, including preparers, auditors, and tax analysts. Adopted methodology: We collected data from 569 accounting professionals using a survey questionnaire, in partnership with the Brazilian Accountants Association (Conselho Federal de Contabilidade, or CFC), a federal agency with the mandate of guiding, regulating, and supervising the accounting profession in Brazil, to assess professionals’ cognitive reflection ability, collect their demographic characteristics, and evaluate their assignment of numerical values to probabilistic expressions. Analyses: We employed t-tests, median tests, and standard deviation tests; we also conducted several robustness tests that replicated our main results. Findings: Our results confirm that reflective accountants are more conservative in their probability assessments than their impulsive peers. Our findings have three main implications. First, standard-setters could avoid the use of or develop guidance about terms with low communication efficiency. Second, analysts and standard-setters should consider that the comparability of accounting information across firms depends on the preparers’ cognitive reflection ability. Third, we present an additional explanation (accountants’ cognitive reflection ability) for accounting conservatism and differences in the interpretation of uncertainty expressions.

Keywords: Reflectivity, impulsiveness, conservatism, aggressive, probabilistic expressions, uncertainty expressions, cognitive reflection.

International Journal of Information Technology & Decision Making, v. 22, n. 4, pp. 1371-1402. Abstract: In this paper, we propose a robust ABC classification for inventories using a hybrid technique for order of preference by similarity to ideal solution-alternative factor extraction approach (TOPSIS-AFEA) as the cornerstone method to calculate and rank importance scores for each item in stock. This is done to mitigate multicollinearity that may exist among different inventory criteria, which artificially inflates total data variance. Besides, and differently from previous research, information reliability techniques such as information entropy and gray relational analysis (GRA) are used as an auxiliary tool to differentiate alternative ABC methods proposed in the literature in terms of the principle of maximal entropy. This principle states that the probability distribution that best represents the current state of knowledge given prior data is the one with largest entropy. Results suggest that the proposed robust TOPSIS-AFEA provides an adequate representation of score ranks that may be computed on different datasets by using existing alternative ABC inventory classification models.

Keywords: ABC inventory, classification, TOPSIS-AFEA, maximal information entropy, GRA, robustness analysis.

Operations Management Research, Vol. ahead-of-print, No. ahead-of-print. Abstract: A metropolitan area’s water supply is imperative to the city’s development. One of the main goals of the water supply utilities is to ensure the availability of water, as a lack of water would cause many social, political, or health problems. Therefore, water supply facilities must be in good condition, efficient preventive maintenance plans must be implemented, and the performance of the maintenance team monitored. In this paper, efficiency indices of Tehran water utility maintenance teams are investigated using different Data Envelopment Analysis (DEA) models. The final scores were then used as inputs to a Fuzzy Inference System (FIS) to assess the efficiency of these maintenance units. Two performance indicators based on DEA, “Availability efficiency” and “Repair time efficiency” are introduced for performance assessment. The Mean Time Between Failure (MTBF) and the Ready To Operate (RTO) are two desirable outputs that are considered in addition to one undesirable output: the Mean Time To Repair (MTTR). In addition, we suggest a new index named MRRW by combining the DEA efficiency with the RRW index. We introduce a novel approach based on DEA combined with FIS methods and the new factors for evaluating water supply maintenance systems, while most previous studies on measuring the efficiency of maintenance teams consider only limited aspects of performance measurement. Based on the results of our study, it became clear that the MRRW measures efficiency better than the traditional RRW measures. We present future improvement strategies based on the output of the FIS.

Keywords: Water supply maintenance, Data Envelopment Analysis (DEA), Risk Reduction worth (RRW), Fuzzy Inference System (FIS).

Cadernos EBAPE.BR, v. 21, n. 1. Abstract: This study investigates the course of the transformations of violence present in the human-animal relationship in multiple periods of time, using artistic expressions to contribute to this theme. The study uses a multidisciplinary approach from the fields of Arts, History, and Philosophy seeking contributions to the literature on marketing and consumer behavior. Visual critical analysis is the methodology used to analyze six works of art from different historical periods and to understand the human-animal relationship over time. Findings suggest that forms of violence are present in the transforming human-animal relationship. The research challenges the marketing domain of the discussion about this relationship, limited to positive experiences with companion animals; it brings interpretations of the ways of violence in the human-animal relationship over time to understand the meanings and practices of the present; adds elements aimed at discussions and reflections necessary for researchers and marketing professionals, on the human-animal relationship and violence.

Information Technology & People, Vol. ahead-of-print No. ahead-of-print. Abstract Purpose: This research was conducted to understand how vulnerable communities used social media (SM) tools to face the impacts of the COVID-19 pandemic. Affected by the lack of information and the absence of effective public policies, residents from slums in the city of Rio de Janeiro displayed new and unexpected uses to SM tools to tackle the health and socio-economic impacts of the pandemic. Design/methodology/approach: The research methodology consisted of a qualitative, exploratory study, combining a series of in-depth interviews with the analysis of various posts, containing videos and texts, extracted from SM during the first six months of the pandemic. The data were collected in the context of 10 different communities in Rio de Janeiro city. Findings: In the context of the pandemic, people combined different uses of SM not only to inform themselves and communicate with others but also to articulate and execute fundraising and food donation strategies within vulnerable communities. Accordingly, this SM use is characterized by improvisation, learning by doing and building resilience, which are all constructs related to the concept of bricolage. Users had no specific SM knowledge, and adjusted these technological tools to emergent new activities in practice, which is characteristic of sociomaterial process. In addition to emphasizing the importance of context for the emergence of the phenomenon, this work also highlights reliability, validity and authority as characteristics related to the citizen-led participation approach that was observed. Research limitations/implications: Future research can develop approaches based on pandemic sociomaterial bricolage (PSB) aspects, which could guide governments and practitioners on building innovative solutions for the use of SM by the population, especially in emergency situations. Originality/value: This study proposes a framework, termed PSB, to represent SM usage promoted by the pandemic context, which emerged from the triangulation of empirical data and an analysis based on the concepts of bricolage and sociomateriality.

ModaPalavra, v. 16, n. 38. Resumo: Este estudo explora a alteridade das coisas e o sublime (HAN, 2019b) para apresentar o conceito de marca de moda sublime expandindo a conceptualização de moda autoral. A partir do caso Ronaldo Fraga, busca-se entender como a sociomaterialidade se manifesta, constituindo a auretização do processo de criação de uma marca de moda. O artigo conta com uma breve discussão sobre moda (MCCRACKEN, 2003) noções de materialidade pela ótica relacional da orientação a objetos (HARMAN, 2018; DELANDA, 2016) e também de alteridade e o sublime (HAN, 2019a; 2019b). Esta pesquisa interpretativista, considera os elementos constitutivos da marca e a visão dos gestores e de suas consumidoras por meio de entrevistas realizadas em 2019, observando os imbricamentos entre criador, objeto e rede de consumo. As análises qualitativas mostram as experiências de arrebatamento da materialidade, antagonismos e os efeitos inusitados e desconcertantes do sublime para o mundo e os que retornam para o criador.

Revista de Administração Contemporânea, v. 27, n. 3. Objective: the paper introduces a framework for conducting interpretive research using deep learning algorithms that blur the boundaries between qualitative and quantitative approaches. The work evidences how research might benefit from an integrated approach that uses computational tools to overcome traditional limitations. Proposal: the increased availability and diversity of data raises the utility of algorithms as research tools for social scientists. Furthermore, tuning and using such computational artifacts may benefit from interpretive procedures. Such circumstances turn the traditional debate between quantitative and qualitative research on its head: the research strategy that likely yields the most assertiveness and rigor is the one that may require vigorous hermeneutic effort. Along these lines, neural word embeddings can be instrumental in allowing researchers to read the data closely before and after interpretation. Conclusions:  to take advantage of the opportunity generated by these new algorithms, researchers may broaden their previous conceptions and adopt a participative point of view.  In the coming decades, the interweaving of computational and interpretive methods has the potential to integrate rigorous social science research.

Intelligent Automation & Soft Computing, v. 36, n. 3, pp. 3175–3190. Abstract: Stock markets exhibit Brownian movement with random, non-linear, uncertain, evolutionary, non-parametric, nebulous, chaotic characteristics and dynamism with a high degree of complexity. Developing an algorithm to predict returns for decision-making is a challenging goal. In addition, the choice of variables that will serve as input to the model represents a non-triviality, since it is possible to observe endogeneity problems between the predictor and the predicted variables. Thus, the goal is to analyze the endogenous origin of the stock return prediction model based on technical indicators. For this, we structure a feed-forward neural network. We evaluate the endogenous feedback between the predicted returns and technical analysis indicators based on the generated residues. It is possible to predict the return. The high accuracy of the model indicates that, during the test period, there is a hit rate close to 76%. Regarding endogeneity, the term of interest and the return are the variables that influence the largest number of indicators. The results will help investors build investment strategies based on this expert system applied to forecasting.

Applied Sciences, v. 13, n. 4, pp. 2618. Abstract: This paper investigates the endogenous source of railway performance in Brazil by focusing on several rail sections. A novel Two-Dimensional Fuzzy-Monte Carlo Analysis (2DFMC) approach is proposed including a multi-attribute decision-making (MADM) model based on type-2 fuzzy sets (T2FS) and a Stochastic Structural Relationship Programming (SSRP) Model based on neural networks. Results suggest that the level of inclination of the rail operators to use the bottlenecked rail sections influences the measurement of idleness, in a chained effect. It is suggested that the balance and coordination among bottleneck, minimum curve radius, and installed capacity are prerequisites to improve railway performance.

Keywords: type-2 fuzzy sets; 2DFMC; rail performance.

Journal of Modelling in Management, Vol. ahead-of-print No. ahead-of-print. Abstract Purpose: The COVID-19 epidemic has brought attention to the variables that influence the mental health of health workers who are entrusted with nursing individuals. Despite the fact that many articles have examined the effects of social media usage on mental health, there is a lack of research synthesizing learning from this body of research. The purpose of this study is to use text mining and citation-based bibliometric analysis to conduct a detailed review of extant literature on health workers’ mental health and social networking habits. Design/methodology/approach: This study conducts a full-text analysis of 36 articles selected on health workers’ mental health and social media using text-mining techniques in R programming and a bibliometric citation analysis of 183 papers from the Scopus database in VOS viewer software. But the limitations of the methods used in this study are that the bibliometric analysis was limited to the Scopus database because the VOS viewer program did not support any other database and the text-mining approach caused the natural processing redundancy. Findings: The bibliometric analysis reveals the thematic networks that exist in the literature of health workers’ mental health and social networking. The findings from text mining identified ten topic models, which helped to find the related papers classified in ten different groups and are provided alongside a summary of the published research and a list of the primary authors with posterior probability through Latent Dirichlet Allocation. Originality/value: To the best of the authors’ knowledge, this is the first hybrid review, combining text mining and bibliometric review, on health workers’ mental health where social networking plays a moderating role. This paper critically provides an overview of the impact of social networking on health workers’ mental health, presents the most important and frequent topics, introduces the scientific visualization of articles published in the Scopus database and suggests further research avenues. These findings are important for academics, health practitioners and medical specialists interested in learning how to better support the mental health of health workers using social media.

Decision Support Systems, v. 171. Abstract: This paper presents an assessment of the Chinese healthcare system in 31 provinces for a 10-year period in light of relevant physical and human resource variables. First, a novel TEA-IS (Trigonometric Envelopment Analysis for Ideal Solutions) model is developed to assess healthcare efficiency at the province level. Machine learning methods are also employed to predict high-low performance and the synergistic Chinese healthcare province in terms of contextual variables. The results indicate that synergy has played a pivotal role in the Chinese healthcare systems, not only by triggering higher performance levels due to the progressive adoption of best practices over the course of time, but also by being closely related to different socioeconomic and demographic variables, such as the illiteracy rate. It is possible to claim that healthcare performance has remained stable in China over the past two decades, performance and synergy at the province level are still heterogeneous.

Keywords: Chinese provinces; Health care; Performance and synergy; Hybrid DEA-TOPSIS; TEA-IS.

International Journal of Finance and Economics, Vol. ahead-of-print, No. ahead-of-print. Abstract: For meeting the external requirements of the Paris Agreement and reducing energy consumption per gross domestic product, China needs to improve its energy efficiency. Although the existing studies have attempted to investigate energy efficiency from different perspectives, little effort has yet been made to consider the collaboration among different stages in the production chain to produce energy outputs. In addition, various studies have also examined the determinants of energy efficiency, however, they mainly focused on technology and economic factors, no study has yet proposed and considered the influence of geographical factors on energy efficiency. In this article, we fill in the gap and make theoretical and empirical contributions to the literature. In this study, a two-stage analysis method is used to analyse energy efficiency and the influencing factors in China between 2009 and 2021. More specifically, from the theoretical/methodological perspective, a multi-activity network data envelopment analysis model is used to measure energy efficiency of different processes in the energy production chain. From the empirical perspective, we attempt to investigate the influence of geographical factors on energy efficiency through a neural network analysis. Meanwhile, the comparisons among different provinces are made. The result shows that the overall energy efficiency is low in China, and China relies more on the traditional energy industry than the clean energy industry. The efficiency level experiences a level of volatility over the examined period. Finally, we find that raw fuel pre-process and industry have a significant and positive impact on energy efficiency in China.

International Journal of Management Science and Engineering Management, v. 18, n. 1, pp. 51-64. Abstract: This study examines critical success factors (CSFs) for supply chain resilience regarding the selection of transportation service providers. Due to extensive global sourcing, many companies are dependent on multiple suppliers and service providers. Using a Delphi approach, this article identifies the CSFs relevant to the resilience of transportation service providers in supply chains. A novel approach using Multiple Criteria Decision-Analysis (MCDA) is then developed to rank a group of CSFs. In particular, the Best-Worst Method (BWM) and Multi-attributive Border Approximation Area Comparison (MABAC) methods are used to rank resilience-related CSFs for transportation service providers in uncertain environments using Hesitant Fuzzy Sets (HFS). Based on our results, hybrid MCDA methods can be applied in order to develop an effective method for determining resilience-related CSFs when selecting transportation service providers in uncertain environments.

Journal of Economics and Business, v. 123. 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.

Computers & Industrial Engineering, v. 175. Abstract: Governments have been challenged to provide temporary hospitals and other types of facilities to face the COVID-19 pandemic. This research proposes a novel multi-attribute decision-making (MADM) model to help determine how, when, and where these temporary facilities should be installed based on a set of critical success factors (CSFs) mapped in an uncertain environment. We portray the available facilities for temporary hospitals based on the CSFs that must be considered to make critical decisions regarding the optimal position based on the government’s strategic decision-making process, thus indirectly providing better services and maximizing resources. In relation to earlier work, this research builds upon hybrid Pythagorean fuzzy numbers to find weights in Best-Worst Methods and rank temporary facilities based on evaluation by an area-based method for ranking. Policy implications and future directions are derived.

Technological Forecasting and Social Change, v. 186, Part A. Abstract: This paper offers a new perspective on the energy efficiency literature by bringing evidence of political contextual factors as the predictors of energy efficiency. Specifically, we posit that the Democrat administration is more energy-efficient considering the reduction of environmental impact, in contrast, the Republican administration is more efficient considering only financial expenditures leading to the production of economic growth. In addition, we predict that political administration tenure is negatively correlated with green energy efficiency and that political distancing moderates the relationship between political party administration and energy efficiency. This study sheds light on these matters by performing an efficiency analysis of fifty North American states through a bootstrap DEA non-parametric model, followed by Tobit regressions to evaluate our hypotheses concerning the effect of the contextual factors on the calculated efficiency scores.

Keywords: Energy efficiency, United States, DEA, Political context.

Expert Systems with Applications, v. 214. Abstract: There are two gaps in the literature: (1) there has been no effort yet considering the black-box productive process, through which financial ratio-inputs are turned into financial ratio-outputs; (2) the previous studies have not yet considered the underlying temporal dependence embedded in the input/output set. Filling in the first gap would contribute to the literature from the methodological perspective, while addressing the second issue is supposed to provide more robust efficiency results. In correspondence to these two gaps, we propose an innovative DEA-Ratio model for undesirable financial output ratios considering weak disposability. In addition, we employ the generalized Auto-Regressive Moving Average model to analyze temporal dependence in the input/output set, which allows us to project the efficiency levels five year ahead. We apply our proposed method to a sample of 124 OECD banks over a twelve-year time window.

Keywords: Banks; Input–output analysis; Stochastic model applications.

Mathematics, v. 10, n. 16. Abstract: Determining success factors for managing supply chains is a relevant aspect for companies. Then, modeling the relationship between inventory cost savings and supply chain success factors is a route for stating such a determination. This is particularly important in pharmacies and food nutrition services (FNS), where the advances made on this topic are still scarce. In this article, we propose and formulate a robust compromise (RoCo) multi-criteria model based on non-linear programming and time-dependent demand. The novelty of our proposal is in defining a score that allows us to measure the mentioned success factors in a simple way, in meeting together all three elements (RoCo multi-criteria, non-linear programming, and time-dependent demand) to state a new model, and in applying it to pharmacies and FNS. This model relates inventory cost savings for pharmacy/FNS and success factors across their supply chains. Savings of inventory costs are predicted by lot sizes to be purchased and computed by comparing optimal and true inventory costs. We utilize a system that records the movements and costs of products to collect the data. Factors, such as purchasing organization, economies of scale, and synchronized supply, are assumed using the purchase system, with these factors ranked on a Likert scale. We consider multilevel relationships between savings obtained for 79 pharmacy/FNS products, and success factor scores according to these products. To deal with the endogeneity bias of the relationships proposed, internal instrumental variables are employed by utilizing generalized statistical moments. Among our main conclusions, we state that the greatest cost savings obtained from inventory models are directly associated with low-success supply chain factors. In this association, the success factors operate as endogenous variables, with respect to inventory cost savings, given the simultaneity of their relationship with cost savings when inventory decision-making.

Financial Innovation, v. 8. Abstract: The literature gap in microfinance paradox of double bottom line (financial performance vs. outreach) has always been an interesting area of research. This paper proposes a theoretical model most suitable for Islamic Microfinance Institutions (MFIs) which enables Islamic MFIs’ to operate together with the existing financial models compliant with Islamic Shariah Law. This model is based on a distributed verification/decision-making process that might be realized (but not necessary) through blockchain. Among the available distributed verification techniques, blockchain technology is an attractive emerging computing paradigm due to its decentralized, immutable, shared, and secure data structure characteristics. This model proposes three significant propositions. First, sharing information through blockchain will allow a transparent network in MFI operations, which will raise confidence for donors resulting in a causal effect of a relatively lower profit rate to be charged by the MFIs. Second, the consensus mechanism will enable risk-sharing, a character of Islamic finance; thus, the MFIs will operate without any collateral for low-risk firms. Third, the double bottom line of MFIs’ long-lasting paradox would be solved. As for practical implication of this proposed model, the causal impact of lower cost investment by the lenders would increase social welfare because of no collateral and no initial wealth requirement. The proposed model proposes a credit rationing approach where profit can be negative. No collateral will be used when calculating the creditworthiness of a borrower.

Keywords: Blockchain, Islamic microfinance, Double bottom line, Distributed verification.

Socio-Economic Planning Sciences, v. 84. Abstract: Loyalty towards digital health services has received unprecedented attention and acceptance during the Covid-19 pandemic period. However, whether this popularity will be retained into the future and the factors that can influence such loyalty is undetermined. This paper provides insight into this issue through a cross-cultural examination of the influence of digital service quality (e-quality) on consumer satisfaction and loyalty (e-loyalty) in the digital health service sector during a pandemic. A fuzzy-set qualitative comparative analysis (fsQCA) is applied using a sample of 50 customers drawn from different professions across different countries who actively showed loyalty towards digital health during the pandemic. Research constructs evaluation for reliability and internal consistency was subsequently performed using Cronbach’s alpha and Correlation analysis. The results reveal a significant positive relationship between service quality and the twin outcomes of consumer satisfaction and loyalty, while the findings established satisfaction as a prominent mediator for digital health. Findings from the fsQCA analysis identified four core factors that underpin loyalty in digital health platforms. Alternative paths have been identified based on gender, current education status, and other professions. In addition, two topologies are introduced taking digital health services from different platforms during the pandemic. Because of the primary nature of the data, this is first-hand experience gathered from the people who are directly or indirectly involved in receiving help from digital health services in a pandemic context. The application of the fsQCA technique for examining loyalty towards digital health services is applied in the e-health or digital health literature for the first time. The study findings will assist digital health service providers seeking insight into the factors that influence loyalty of e-health service consumers, enabling them to focus more accurately on the service quality dimensions that are effective in influencing consumer satisfaction and retention. The findings of this study contain a number of contributions, illustrating different topologies towards digital health that provide educators and policymakers with valuable insights.

Abstract Purpose: Although there has been a significant amount of research on Smart Tourism, the articles have not yet been combined into a thorough literature review that can examine research streams and the scope of future research. The purpose of this study is to examine the literature on the impact of deploying the Internet of Things (IoT) in tourism sector development to attract more visitors using a text mining technique and citation based bibliometric analysis for the first time. Design/methodology/approach: This study uses R programming to do a full-text analysis of 36 publications on IoT in tourism and visualization of similarities viewer software to conduct a bibliometric citation analysis of 469 papers from the Scopus database. Aside from that, the documents were subjected to a longitudinal study using Excel and word frequency using a trending topic using the R-tool. Findings: Results from the bibliometric study revealed the networks that exist in the literature of Tourism Management. With the use of log-likelihood, the findings from text mining identified nine theme models on the basis of relevancy, which is presented alongside an overview of the existing papers and a list of the primary authors with posterior probability using latent Dirichlet allocation. Originality/value: This study examines tourism literature in which IoT plays a significant role. To the best of the authors’ knowledge, this study is the first to combine text mining with a bibliometric review. It significantly analyzes and discusses the impact of technology in the tourism sector development on attracting tourists while presenting the most important and frequently discussed topics and research in these writings. These findings provide researchers, tourism managers and technology professionals with a complete understanding of e-tourism and to provide smart devices to attract tourists.

Brazilian Business Review, v. 20, n. 1, pp. 76-98. 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.

Information Technology for Development, Vol. 29, n. 2/3. 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.

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.

Business Ethics, the Environment & Responsibility, v. 32, n. 1, pp. 179-190. 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.

Economic Systems, v. 47, n. 2. 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.

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.

IEEE Transactions on Engineering Management, v. 70, n. 3, pp. 1076-1088. 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.

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.

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.

Information Technology & People, v. 36, n. 6, pp 2280-2311. 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.

Transplantation Proceedings, v. 54, n. 8, pp. 2069-2074.  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.

Cadernos EBAPE.BR., v. 20, n. 6. 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.

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.

Asian Journal of Economics and Banking, v. 7, n. 1, pp. 25-44. 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.

Journal of Modelling in Management, v. 18, n. 3, pp. 842-875. 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.

Journal of Decision Systems, v. 32, n. 2, pp. 356-383. 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.

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.

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.

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.

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.

IMA Journal of Management Mathematics, v. 34, n 3, pp. 541-580. 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.

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.

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.

Journal of International Business Policy, v. 5, pp. 417-443. 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.

Sport, Business and Management, v. 13, n. 1, pp. 93-117. 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.

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.

Annals of Operations Research, v. 315, n. 2, pp. 1373–1398. 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.

European Journal of International Management, v. 21, n. 1. 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.

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.

International Journal of Entrepreneurial Behavior & Research, v. 28, n. 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.

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.

Tobacco Control, v. 32, n. 1, pp. 13-18. 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.

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.

Latin American Business Review, v. 24, n. 2, pp. 157-175. 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.

Emerging Markets Finance and Trade, v. 59, n. 1, pp. 60-77. 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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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: SRISK, SES 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.

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.

Advances in Consumer Research, v. 49, pp. 113-116. Abstract: Along their evolutionary trajectories, digital influencers can get involved in a series of transgressive events. Through a longitudinal netnography, this research aims to identify what transgressions are and how they differ according to their nature. Analyzing the transgression itself, we contribute by presenting a typology that goes beyond commercial relations.

Abstract: This ethnographic study explores the process of de-domestication through feminist experiences cycles resulted from a constant search for emancipation until the suspension generated by the virtualization of experiences. This search guided through collective experiences loose meaning in a domestic space with technologies in a social isolation context.

Advances in Consumer Research, v. 49, pp. 78-81. Abstract: Violence is framed here as an object of consumer desire that can impact consumer’s behavior towards a product and impact advertising risks and public health campaigns. We contribute with a list of issues in need of further research in marketing, consumer behavior, and public policy.

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.

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.

Keywords: Social networking sites, uses, motivations, integrated model.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Advances in Consumer Research, v. 48, pp. 66-71. Abstract: This paper extends research on legitimacy in the marketing field by addressing the tensions involved in constructing legitimacy for social media influencers.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Cadernos EBAPE.BR, v. 19, n. spe, pp. 792-810. Resumo: Este artigo trata dos fatores que influenciam a utilização de serviços de governo eletrônico pelos cidadãos.

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.

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.

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.

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.

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.

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.

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.

Keywords: Transportation footprint, Macro-economic variables, Markowitz Portfolio Selection, Neural Networks, Variable reduction.

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.

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.

Keywords: Prices, Consumers, Fairness, Culture paper type research paper.

REAd. Revista Eletrônica de Administração, v. 19, n. 3, pp. 769-819. 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.

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.

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.

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.

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.

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.

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.

Tecnologias de Administração e Contabilidade, v. 3, n. 1, pp. 16-41. Resumo: O caso atende aos seguintes objetivos educacionais: (a) entender o processo pelo qual uma empresa de serviço, do setor de refeições rápidas, internacionaliza-se, aplicando teorias de internacionalização, tanto econômicas quanto comportamentais, a uma situação específica; (b) analisar e avaliar os riscos e dificuldades do processo de internacionalização; (c) colocar em discussão os sistemas de franquias internacionais e a adequação ou inadequação dos mesmos para o atendimento dos objetivos de internacionalização. O caso apresenta o relato da evolução de uma empresa de fast-food e o início de seu processo de internacionalização. No momento do caso, a direção da Brazil Fast Food Corporation, holding que detinha o controle da rede de fast-food Bob’s, considerava se deveria ou não aprofundar o processo de internacionalização da empresa. Outras considerações envolvem a seleção de parceiros e a preparação prévia para o ingresso em um mercado estrangeiro. O caso pode ser utilizado em cursos de graduação e pós-graduação – stricto e lato sensu – que tratem de temas relativos à gestão internacional e, em particular, à gestão internacional de empresas franqueadoras. Pode ser utilizado, também, em workshops de discussões sobre as dificuldades e soluções encontradas por empresas brasileiras em seu processo de internacionalização e para treinamento de agentes atuantes junto às empresas. O caso foi escrito utilizando-se exclusivamente fontes secundárias.

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.

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.

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.

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.

Keywords: Brazilian airports, Flight consolidation, Airport efficiency.

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.

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.

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.

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.

Palavras-chave: Heurísticas, Afeto, Avaliabilidade, Julgamento.

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.

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.

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”.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Advances in Consumer Research, v. 42, pp. 361-365. Abstract: The study investigates facets of brand cultural resonance by the case of Brazilian demonstrators appropriating a FIAT´s campaign. The analysis of cultural texts and in-depth interviews suggests cultural resonance as an element of brand protection in turbulent contexts and highlights brands as a collective shared repertoire in increasingly fragmented societies.

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.

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.

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.

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.

Internext, v. 9, n. 3, pp. 78–94. Resumo: O presente estudo visa explorar a forma como uma empresa brasileira de software de segurança internacionaliza-se e quais as vantagens competitivas que advém deste processo. A metodologia escolhida foi a qualitativa, com a utilização de estudo de caso. Os resultados obtidos demonstraram que, após a internacionalização, a empresa analisada passou a ser percebida pelos clientes no Brasil como mais eficiente e detentora de tecnologias mais modernas. Além disso, a acirrada competitividade do mercado norte-americano obrigou que a empresa atualizasse e, até, reinventasse seus produtos e processos, obtendo, como resultado final, um software com funcionalidades e características superiores a de seus concorrentes nacionais e internacionais. O estudo pretende contribuir para a compreensão do processo de internacionalização da indústria de software brasileira, identificando os pontos que transformaram essa empresa em um caso singular no segmento.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

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

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.

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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

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.

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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 regres
