title: Psychosocial and Organizational Antecedents of Knowledge Sharing in the Workplace

description: ABSTRACT Objective: this paper proposes and evaluates a causal model to explain knowledge sharing among peers in the workplace. The proposed model, based on the Theory of Planned Behavior, includes psychosocial factors (transformational leadership, workgroup identification, and shared understanding) and organizational factors (knowledge sharing opportunities and formalization of knowledge sharing processes) as antecedents of individuals' attitudes, perception of subjective norms associated with their group and their direct supervisor, and intention and effective knowledge-sharing behavior. Methods: the model was statistically tested using structural equation modeling techniques with data provided by 131 customer service employees of a large Brazilian telecommunications company. Results: the results indicate that the psychosocial elements have a strong influence on knowledge sharing attitudes and practices. The hypotheses associated with behavioral control have not been confirmed. Moreover, the intention to share knowledge does not seem to be affected by the subjective norms associated with the individual's direct supervisor, but only by those related to their group. Conclusions: the cognitive proximity between group members, reflected in their perception of shared understanding, was an important element in the elicitation of attitudes favorable to knowledge sharing. Additionally, individuals with greater identification with their group tended to have more positive attitudes toward sharing their knowledge. This attitude tends to be more positive when the individual's direct supervisor adopts a more transformational leadership style. The influence of leaders seems to extend from the development of a culture of knowledge exchange and diffusion of principles that stimulate this exchange, to the creation of opportunities to share knowledge through the active management of knowledge diffusion in their teams.

title: Portfolio Management under Multiple Regimes: Strategies that Outperform the Market

description: ABSTRACT Context: regime switching models in asset allocation under the stochastic differential utility function were not included in the literature until Campani, Garcia and Lewin (2020) model. This function is at the knowledge edge because, more realistically than the others, it separates the investor main risk parameters. Such configuration, however, becomes so complex that it does not admit an exact solution in the literature and Monte Carlo simulation is not efficient to solve the problem in real time. The model solves that issue with an approximate solution, which is fairly accurate for allocation, and our article offers the first application outside the North American scenario. Objective: evaluate portfolio strategies based on the model on screen and compare their performances with the returns of the main benchmarks of the market. Methods: we propose strategies with and without short selling under four unobservable economic regimes based on the asset returns from: cash (CDI), fixed income (IMA-G), domestic stocks (IBrX-100) and international stocks (S&P 500) in Brazilian Reais. With these parameters, we estimate the regimes probabilities and define each asset weights in the portfolios (multi-regime strategies). Then, we compare these portfolios performances with market indexes and the myopic models (single regime strategies), calculating the statistical significance of the results using Wilcox test. Results: with this research, we pioneer identifying for the first time four economic regimes in Brazil for portfolio optimization. The results indicate that (i) the portfolio policy strongly depends on the current economy state; and (ii) the proposed strategies outperform the market in terms of returns and Sharpe ratio. Conclusion: regime switching models are relevant for portfolio management, and strategies based on these models might imply in solutions that benefit investment managers.

title: The Power of Psychological Capital: The Strength of Beliefs in Entrepreneurial Behavior

description: ABSTRACT Objective: this research aimed to analyze entrepreneurial behavior from the components of psychological capital and cognitive social theory, from the human agency perspective. Methods: we used qualitative research along with in-depth interviews, conducted with 21 entrepreneurs with different profiles. The speeches were interpreted by content analysis and expanded into theories. Results: the results show that the actions developed by the interviewees during the creation and development businesses are aligned with the entrepreneurial characteristics, according to the literature, without distinction of gender, age or length of experience. As coping mechanisms for challenges and opportunities, these individuals express their beliefs in behaviors of self-efficacy, optimism, hope, resilience, intentionality, anticipation, self-actualization, and self-reflection. Conclusions: these findings indicate that the psychological forces act as fundamental elements for the success of the entrepreneur, which is essential to being understood in the theoretical and managerial scope and as a relevant element to the research.

title: Environmental Responsibility, Psychological Distance, and Environmental Consumption: Mediation in Accounting Students

description: ABSTRACT Objective: this study aimed at analyzing the relationship between psychological distance and environmental consumption, embodied in the intention to purchase and loyalty to pro-environmental products, mediated by environmental responsibility. Methods: 113 responses obtained through a survey conducted with academics from the Accounting Sciences course were analyzed, using the structural equation modeling technique to identify the proposed relationships and the possible mediating effect between the constructs. Results: the results illustrate the existence of partial mediation of environmental responsibility in the relationship between psychological distance and the intensity of purchase and total with the loyalty of consumers. The non-rejection of the research hypothesis exposes the importance of analyzing psychological elements regarding to the consumption behavior of pro-environmental products. Conclusions: theoretical contributions indicate that environmental responsibility is capable of promoting the consumption of pro-environmental products. In practical terms, Accounting courses can incorporate discussions about socio-ethical-environmental values, expanding classroom debates about environmental responsibility beyond the financial aspects specifically aimed at creating economic value for the organization.

title: Increase in Leverage Driven by International Financial Reporting Standards Adoption

description: ABSTRACT Context: adoption of International Financial Reporting Standards (IFRS) in Brazil has improved corporate governance practices and information available to investors, providing greater transparency. Despite its mandatory effect, companies listed in B3 tiers (Novo Mercado and Level 2) were already accustomed to using it, allowing a comparison with firms affected by the law. Objective: analyze the influence of IFRS adoption on the capital structure of publicly traded Brazilian companies by comparing firms that only began to adhere to it by the new law (Regular and Level 1) with firms that adopted IFRS before it went into effect (Novo Mercado and Level 2). Method: we performed a quasi-experimental design via difference-in-difference (DID) estimator to compare leverage levels of firms segmented in treatment and control groups before and after IFRS. Conclusions: we found that the treatment group companies had higher market leverage after IFRS adoption, influenced by the greater information disclosure and, consequently, reduction of investors’ perception of risk. In addition, the differences between groups in DID analysis were influenced by the greater effect on market leverage for treated companies and on net indebtedness for the control ones. Furthermore, we confirmed the pecking order theory assumptions for most of the covariates.

title: Professional Socialization from the Perspective of Female Surgeons: Challenges and Career Achievements

description: ABSTRACT Objective: aiming to contribute to the field of investigation on the association between work and gender, the study focuses on the medical surgeon profession, which has a low female participation rate. Thus, the aim of the study is to understand how professional socialization of female surgeons occurs, with an emphasis on gender and work relationships. Methods: this is a qualitative, descriptive study, comprising in-depth interviews carried out with 10 female surgeons, assessing their perceptions about the analysis categories belonging to the theoretical model of professional socialization: the looking-glass self, the establishment of duality, and the adjustment of the self-concept. Results: the interviewees’ greatest interest in the surgical area originated from personal characteristics they thought were important to a surgeon, in addition to the desire to solve the patient’s problem in a more practical and objective way. Conclusions: we observed that there are conflicts between the lay and professional culture and that the professional insertion was characterized by challenges, such as prejudice and difficulties in reconciling the personal and professional aspects of life. The study increased the understanding of how the job market incorporated the female surgeons, since it is a predominantly male area characterized by many stereotypes.

title: Avon Brazil: Optimization of Logistics Processes in a Direct Selling Company

description: ABSTRACT This case study aims to develop in each student analytical competencies by evaluating current logistics processes and, from this understanding, to use the knowledge gained on tools and theories of continuous improvement to propose solutions and discuss strategic alternatives for the company to improve its processes. Efficiency in logistics operations plays a key role in the results of direct sales companies because there are thousands of customers and daily deliveries that bring complexity to the process. The new Supply Chain Director took over the position in a difficult period of falling market in the country. Thereby he implemented internal discussions to evaluate the status of various processes and to engage leadership. He intends to find ways to improve logistics processes through capital investments or by using continuous improvement tools that could provide cost reductions and increase service levels. The case can be used in undergraduate courses, graduate courses, and also in professional education in themes related to business management, supply chain, logistics, and industrial operations.

title: Going the Extra Mile: Impact of Individuals’ Behavior on Information Technology Governance

description: ABSTRACT Objective: this work emphasizes the information technology governance (ITG) behavioral expression and aims to identify whether individual behavior contributes to the increase of the perceived maturity of the ITG mechanisms. The organizational citizenship behavior (OCB) concept was the base to develop a model of relations between individual behavior and ITG maturity. Methods: we carried out a survey with 243 IT personnel of the executive branch of a Brazilian state government. We used partial least squares as data analysis technique. Results: the findings show the existence of a positive and significant relationship between the variable spirit of initiative and the perceived maturity of the ITG mechanisms. Conclusions: the impact of ITG changes in individuals’ behavior needs to be considered, which reinforces that ITG is a critical resource for implementing public policies and executing governmental strategies. In order to raise the IT governance maturity, managers should foster the spirit of initiative in their teams, acting on their antecedents such as feelings of control, complexity, self-efficacy, and responsibility for changes. Consequently, individuals can make a deliberate decision, constantly evaluating the likely outcomes of their behaviors in favor of the adoption of ITG mechanisms.
