Resumo Esse estudo investiga em que medida os mecanismos de governança externos à firma afetam a alavancagem de uma amostra de 7.490 empresas de 40 países. O diferencial do estudo está na distinção entre os mecanismos que afetam a proteção dos acionistas minoritários daqueles que afetam os direitos dos credores. Os resultados sugerem que as empresas se alavancam de maneira coerente ao previsto pela Teoria da Pecking Order (POT). Observou-se que os mecanismos associados à proteção de ambas classes de investidores (i.e., acionistas e credores) influenciam significativamente a estrutura de capital das empresas. Quando a proteção é alta, as empresas tomam menos dívida. Os resultados mostraram-se robustos a diversas variações no modelo estudado e indicam que, quando a proteção aos investidores externos é maior, as firmas tomam menos dívida, possivelmente com a finalidade de restringir o papel monitorador da dívida sobre a discricionariedade dos insiders.

This article analyzes the relationship between opaque assets and the risks, returns and inflows of hedge funds. In particular, we use a unique dataset containing information required by a Brazilian regulator to evaluate the amount invested by funds in forward and future contracts, swaps and options in the context of qualified and non-qualified investors. Our results show a positive association between the positions in derivatives and the variations in risk and a negative association between derivatives (especially swaps) and the funds’ monthly performances. This means that the use of more derivatives is related to higher risk (total and systematic) without the benefit of higher return. Hedge funds adopting leveraged operations with derivatives also present a lower annual performance. In general, there is significant evidence that swaps are related to fund inflows in a negative way with regard to qualified and non-qualified investors.

The aim of this paper is to propose a methodology for innovation management, which aims to focus on the needs of micro and small technology-based companies. The development of this methodology occurs in the context of the Brazilian National Project Financier (Financiadora de Estudo e Projetos [FINEP]) program for the structuring of Innovation Management Support Centers (Nucleos de Apoio a Gestao da Inovacao [NAGI]), focusing on the elaboration of Innovation Management Plans and Projects in Brazilian companies. A qualitative research was developed in two main stages for the development of the present methodology. The first phase developed a literature review of the main elements for innovation management, especially in the context of micro and small enterprises. In the second phase, five NAGIs were selected from the 24 those approved by MCTIC (now MCTIC: Ministry of Science, Technology, Innovation and Communication) and FINEP, according to their trajectory up until the time of the research in January 2014. The proposed methodology - Route of Innovation – is based on the Resource Based View (RBV) within a procedural and playful perspective that relates the innovation process to navigating a route. The logic of the islands in the Route of Innovation is based on the stages of the innovation process. The purpose of this approach was to make the methodology easily understood and implemented by micro and small companies.
本文的目的是提出一种创新管理方法，旨在关注微型和小型科技型公司的需求。这种方法的发展是在巴西国家项目融资(Financiadora de Estudo e Projetos [FINEP])计划的背景下进行的，该计划旨在建立创新管理支持中心(Nucleos de Apoio a Gestao da Inovacao [NAGI])，重点是在巴西公司中制定创新管理计划和项目。本方法的发展分为两个主要阶段进行了定性研究。第一阶段对创新管理的主要要素进行了文献综述，特别是在微型和小型企业的背景下。在第二阶段，根据截至2014年1月研究时的发展轨迹，从MCTIC(现为科学技术创新通讯部)和FINEP批准的24个nagi中选出5个。提出的方法——创新之路——是基于基于资源的观点(RBV)的程序和有趣的视角，将创新过程与导航路线联系起来。创新之路中岛屿的逻辑是基于创新过程的阶段。这种方法的目的是使该方法易于被微型和小型公司理解和实施。

Despite the large number of studies on happiness at work in organizations, they are disperse and divergent and thus inconclusive. This makes the evolution of research on this topic and practicioners’ decision-making regarding the happiness at work difficult. Based on a comprehensive literature review, this article proposes a perspective that encompasses the knowledge developed so far. To do so, it explores three issues: how happiness at work has been defined; the impact of happiness at work on organizational performance; and, what makes people happy at work. The integrated perspective this paper advances draws on the principles from Kahneman and Riis (2005), mainly focusing on antecedents of happiness at work and their impact on individual behavior in the organization.

This study consists of analyzing the transactional relationship between farmers and authorized contractors at Ceasa-MS. In order to reach the objective proposed by the study, 78 semi-structured questionnaires were distributed among the contractors at Ceasa-MS. The questionnaires had as a theoretical framework the TCE in conjunction with the plural forms theory. Analyzing the transaction dimensions between the farmers and contractors at Ceasa-MS, we perceived that the assets studied possess: (a) average specificity; (b) uncertainty of the transactions is high; (c) and transactions occur on a recurring basis. Keeping such dimensions in mind, the TCE theory foresees that those transactions should happen in hybrid form, however the contractors served themselves with vertical integration and plural forms, the latter being the combination of hybrid forms and vertical integration. The presence of plural forms is explained by the ambiguity in the governing structure and the complexity in the way transactions are monitored. We verified that the use of plural forms or the simultaneous use of vertical integration with hybrid forms within all organizational arrangements, to reduce the transaction cost for the contractors as the combined positive aspects of the hybrid forms and vertical integration nullify their weak points.

Court caseload management is of key importance for guaranteeing the adjudication of cases and depends on how judges and administrative assistants deal with their workload. Results from several studies indicate that an increase in court caseload tends to generate an increase in the judge’s production. However, some authors argue that this relationship is far more complex. To develop a fuller understanding of this relationship we tested an array of direct and moderating hypotheses. We used secondary data from 566 judges working in first trial courts in the State Justice System of Sao Paulo, Brazil. The results indicate a direct and positive relationship between court caseload and judge production, but the strength of this relationship depends on court specialty. The findings also indicate that the number of administrative assistants, judge experience and the number of places a judge works all moderate the caseload-production relationship. The results contribute to the development of strategies to address the delays and congestion of courts, two of the main Brazilian Judiciary problems.

This study was conducted using a contemporary approach of Strategy as Social Practice (SSP) highlighting discursive practices. This research aimed to understand how discursive practices contributed to a community higher education institution’s strategic practices. We adopted a qualitative approach as suggested by the literature for research in SSP. We chose to do a single case study and collected data through systematic observation of five strategic planning meetings, qualitative interviews with managers at five hierarchical levels of the university, and document analysis. We used Peircean semiotic analysis for data analysis (Dias, 2015). Based on this analysis, we determined what contributed to strategizing: the historical and social context; a power relationship between the academic area strategists and a means, which is implicit in the discursive practices. The voices of practitioners also emerged from the data: leader, manager and external consultant. From the SSP perspective, the decision-making process may have brought limitations since the one hundred and eleven strategists did not participate in all stages of planning, especially in terms of the means.

This research describes the development process for a proposal on Certification and Classification regarding the Nutritional Quality of buffet restaurants, to be applied by city Health Inspection Services. The process is characterized by co-production in the design of the public service, aimed at improving public health by fighting Non-Communicable Chronic Diseases (NCD). People and organizations with different knowledge on the subject participated in the process, which consisted of seven meetings. The steps for the inspection, certification and classification of restaurants were co-produced according to criteria, grades, classification and symbols. The participants considered the proposal development process to be adequate overall. However, it is necessary to invest in other approaches towards consumers and restaurant representatives in order for them to be more active participants. This research has the potential to contribute to help other sectors of city Health Inspection and other public organizations co-produce working tools; to make it easy for consumers to choose healthy food; to help improve nutritional quality of food served in buffet restaurants; and finally to contribute to fighting NCD in cities.
