ENTREPRENEURIAL ECOSYSTEMS: A CONFIGURATIONAL RESEARCH APPROACH
No full textThe entrepreneurial ecosystem approach has emerged as a framework capable of providing a systemic understanding of entrepreneurship. Considering that entrepreneurial ecosystems admit different configurations, this article aims to stimulate a reflection on the application of the configurational approach in the analysis of entrepreneurial ecosystems. An analysis model based on six dimensions of entrepreneurial ecosystems is indicated: geographic breadth, sectorial diversity, mode of governance, degree of maturity, innovative effort, and environmental munificence. This proposal is justified by indicating a possibility for a more subtle and rigorous understanding of entrepreneurial ecosystems, allowing for more precise and reliable policy recommendations for the creation and strengthening of entrepreneurial ecosystems
AUDITORIA INDEPENDENTE E DIVULGAÇÃO ENVIRONMENTAL, SOCIAL AND GOVERNANCE (ESG)
No full textDisclosure of environmental, social, and governance (ESG) information, on the one hand, reduces certainties and certainly minimizes agency costs. On the other hand, it can disguise opportunistic behaviors by managers, who may start to escape these practices for personal benefits. Thus, one can observe the positive or negative effects of ESG information depending on the interests of the agents involved in its disclosure. One way to minimize these conflicts is through audit work. Thus, the essay aims to discuss the role of independent auditing in ESG information evidenced by entities in the light of Agency Theory.A divulgação de informações de environmental, social and governance (ESG), por um lado, reduz as incertezas, contribuindo para minimizar os custos de agência. Por outro, pode disfarçar comportamentos oportunistas dos gerentes, que podem investir, excessivamente, nessas práticas em prol de benefícios pessoais. Assim, podem-se observar impactos positivos ou negativos das informações de ESG, a depender dos interesses dos agentes envolvidos na sua evidenciação. Uma das formas de minimizar esses conflitos é por meio do trabalho de auditoria. Dessa forma, o ensaio tem como objetivo discutir o papel da auditoria independente nas informações ESG, evidenciadas pelas entidades à luz da Teoria da Agência
MODELOS DE MATURIDADE EM GESTÃO DE PROCESSOS: UMA REVISÃO SISTEMÁTICA DA LITERATURA
No full textThe number of maturity models proposed in Business Process Management (BPM) has significantly increased. However, process management maturity models use still lack widespread acceptance in practice. In light of this, a systematic literature review was conducted to gain a general understanding of the existence, characteristics, and usage of maturity models in process management. Studies conducted between 2012 and 2020 in major databases were examined. The studies were selected using the Proknow-C method. Subsequently, a bibliometric and content analysis of the articles was performed. It was found that the main measurement factors of the models are process lifecycle, culture, IT, and performance. The research trend is toward the development of new models. Furthermore, it was discovered that the correct choice of models is directly related to the success of their application, which can contribute to greater acceptance of the use of maturity models in practice.A quantidade de modelos de maturidade propostos na área de Business Process Management (BPM) aumentou consideravelmente. Porém, o uso de modelos de maturidade de gestão de processos ainda não apresenta ampla aceitação na prática. Diante disso, realizou-se uma revisão sistemática da literatura para obter uma compreensão geral da existência, características e uso de modelos de maturidade em gestão de processos. Examinaram-se estudos realizados entre 2012 e 2020 nas principais bases de dados. Os estudos foram selecionados conforme o método Proknow-C. Depois se realizou uma análise bibliométrica e de conteúdo dos artigos. Descobriu-se que os principais fatores de medição dos modelos são ciclo de vida dos processos, cultura, TI e desempenho; a tendência das pesquisas está no desenvolvimento de novos modelos; e a correta escolha dos modelos está diretamente relacionada com o sucesso de sua aplicação, o que pode contribuir para maior aceitação de uso de modelos de maturidade na prática
FROM LEADERSHIP TO HOLDERSHIP: A PARADIGM SHIFT IN ORGANIZATIONAL DYNAMICS
No full textThis article investigates the evolution of leadership, delineating the shift from traditional hierarchical and leader-centric approaches to the emerging concept of “holdership”. Drawing from Winnicott’s perspective, the aim is to provide an initial description and comprehension of the notion of holdership, outlining its principles and characteristics in contrast to conventional leadership paradigms. The introduction of the concept of holdership serves as a response to gaps in traditional leadership theories, with the potential to enhance our understanding of organizational dynamics and drive transformative changes within organizations. To achieve it, a methodology involving literature review and in-depth case study analysis is adopted, with a focus on selecting relevant publishings. The findings affirm the applicability of holdership in the current landscape of business and management, particularly within innovation-oriented organizations. Holdership promotes leadership grounded in authenticity, ownership, collective responsibility, transparency, and psychological safety. This article advocates for the adoption of holdership as a lens for analyzing contemporary organizational dynamics influenced by ongoing socio-cultural, economic, and technological transformations. Emphasis is placed on the role of context while highlighting the limitations of charismatic and leader-centric leadership models. Ultimately, holdership is presented as an alternative perspective on leadership, fostering authenticity, innovation, and collective responsibility

INVESTMENTS IN TIMES OF UNCERTAINTY: FORMATION OF PORTFOLIOS USING RANDOM FOREST
No full textObjective: based on a systematic approach using machine learning, this research aims to propose a model of selection and allocation of assets that allows for building profitable and safe portfolios, even in times of insecurity and low predictability.Methodology: we used the machine learning algorithm called random forest to associate the independent variables with a dependent one and learn the probability of positive returns in the month following the data collection. According to the probabilities, the stocks were allocated into long, short, or non-allocated portfolios. Finally, we allocated a share of gold, which is a protection asset much used in times of crisis and uncertainty.Results and contributions: the study reached its goal and demonstrated being possible to build profitable and safe investment portfolios, even in times of greater uncertainty and volatility, as in 2020 due to the Covid-19 pandemic. We found that the model is effective in moments of crisis and also of greater predictability, as in the period from 2016 to 2019 when the stock exchange has an uptrend.Relevance: the relevance of this study points to an unprecedented historical context in Brazil, where uncertainties regarding both the local and world economy have demanded advanced studies of prediction to minimize risks and contribute to results for investors. In addition, we highlight that following a short period of low Selic (2019 to 2021), the Central Bank increased the rate again, raising the interest more in profitable and safer assets than the investment in stocks.Impact on the area: the study has a positive impact on the finance area since studies in this field promote greater stability to investors and thus better capital flow for companies, which, in turn, contribute to society and the growth of the country
