Estudos de marketing e risco para uma empresa especializada em projeto de sistema e prevenção contra incêndio
(Universidade Federal de Minas Gerais, 2025-08-28) Mariana Braga Mançur de Souza
The contemporary business environment of microenterprises, characterized by complexity and intense competitiveness, demands well-founded strategic decisions. In this context, this study examines how marketing and risk analysis approaches can be integrated to enable and foster the sustainable growth of PREVENG Engenharia, a small enterprise operating in fire and panic safety engineering projects (SPCI). Methodologically, it is a field study with a qualitative, exploratory, and descriptive approach, supported by action research, document analysis, and interviews with the company’s partners. Adopting a holistic perspective, the study encompasses concepts such as the 4Ps/8Ps of marketing, the SWOT matrix, the empathy map, the customer journey, and the strategic roadmap. The results reveal that PREVENG Engenharia demonstrates technical quality and personalized service as key strengths, counterbalanced by low visibility, a lean organizational structure, and reliance on word-of-mouth communication. The external environment is marked by a growing demand for regulatory compliance and a shortage of qualified professionals. Furthermore, the findings emphasize the need for a structured digital marketing strategy (website, content creation, Google Ads), a clear market positioning, and systematized processes, all aligned with a five-year roadmap comprising internal structuring, portfolio and value proposition development, automation integration, regional expansion, and brand and certification consolidation. In sum, the objectives were achieved, providing practical contributions and a solid organizational theoretical foundation, built upon the methodological articulation of diverse tools and approaches.
Modelos preditores de contratação de profissionais do futebol baseado em Inteligência Artificial por mecanismos Machine Learning
(Universidade Federal de Minas Gerais, 2025-07-17) Felipe Alexandre de Souza Félix Nunes
This thesis investigates the strategic dynamics involved in the recruitment process of professional football players, with a focus on developing an interpretable decision-support model based on machine learning algorithms, fuzzy logic, and social network analysis. Drawing on an interdisciplinary approach that integrates organisational studies, sports science, and mathematical modelling, the research proposes a methodological solution for evaluating athletes’ technical performance while considering the contextual specificities of contemporary professional football. The study is structured around three analytical axes. The first comprises a bibliometric review, which revealed the emergence of a converging body of literature between sports performance, fuzzy models, and artificial intelligence. The second axis applies social network analysis to over 100,000 international player transfers, identifying patterns of centrality, intermediation, and community formation within the global transfer market—highlighting the strategic roles of countries such as Belgium, Portugal, and Brazil. The third axis presents the development and testing of a fuzzy logic-based performance evaluation model, fuelled by statistics from the Wyscout platform and validated through attributes from Football Manager 2024. The model demonstrated robustness in functional comparisons of players, adhering to the principle of representative design and integrating the tenets of the ecological approach to sports performance. The results indicate the practical usefulness of the tool in supporting decision-making, particularly in talent scouting and efficient resource management. The thesis offers both a theoretical and applied innovation by introducing a flexible scoring system that confronts the subjectivity of traditional scouting methods with analytical criteria, thereby promoting greater strategic rationality in squad composition. Furthermore, the contributions of this work extend to the field of organisational research, by demonstrating how analytical capabilities can become strategic assets in the pursuit of sustainable competitive advantage in global football.
Fecundidade, equidade de gênero e preferência por sexo do filho.
(Universidade Federal de Minas Gerais, 2024-12-30) Júlia Moreira Hastenreiter
Fertility is a highly debated topic in academic circles, yet its future is uncertain. In this regard, Goldscheider, Bernhardt, and Lappegård (2015) argue that gender equity is a key factor in increasing fertility according to the Gender Revolution theory. Therefore, this study aims to investigate whether there is an association between fertility and gender equity in both public and private spheres across various countries, including the United States, addressing the issue of time allocation variation based on the sex of children in the United States. To do so, regression methods were used to assess the associations between fertility, time allocation, gender equity, preferences for the sex of children, and other sociodemographic variables. Thus, this study found evidence supporting the idea of the incomplete Gender Revolution, presenting mixed results regarding gender equity and fertility. Additionally, evidence was found of preferences for one child of each sex in fathers' time allocation in the United States from 2003 to 2019. Specifically, when there is only one child, men appear to prefer sons, allocating more time to their care, as also found by Dahl (2008).
Plano de negócios: estudo de viabilidade técnica e econômico-financeira para um sistema de monitoramento acadêmico voltado ao ensino superior baseado em inteligência artificial.
(Universidade Federal de Minas Gerais, 2025-08-27) Carlos Augusto Reis Bandeira
ABSTRACT This project aims to develop a business plan to assess the technical and financial feasibility, as well as the scalability, of creating a continuous monitoring structure based on artificial intelligence for higher education. Continuous monitoring will make it possible to identify academic difficulties in real time, offer personalized feedback, and propose effective pedagogical interventions, benefiting both students and teachers. In addition, the project seeks to reduce academic dropout rates, improve student performance, and optimize the educational management process. It is expected that the implementation of the project will contribute to innovation in higher education by strengthening student retention and promoting a more personalized and effective education, while making the solution viable in economic and social terms.
Activism short selling: impacto nos retornos das ações, aquisição de superioridade informacional e seleção de alvos
(Universidade Federal de Minas Gerais, 2025-06-17) Guilherme Ayres Jameli
This research investigates activism short selling, a form of short selling in which investors not only take short positions but also release critical reports about target firms, seeking to trigger declines in their stock prices. The study aims to understand which criteria and information sources guide activist short sellers (ACSS) in target selection and to evaluate the impact of their disclosures on stock returns. To this end, a documentary analysis of ACSS reports from 2017 to 2023 was conducted, complemented by statistical analyses, including mean difference tests, logistic regression, and event study methodology. The documentary analysis revealed that the issues most frequently identified by ACSS in their targets include fraud and poor accounting quality, legal risks, deficiencies in business models, managers with a poor track record, stock price manipulation, concerns related to independent auditing, and financial distress. To identify these red flags, ACSS combine private data with complexly processed public information, consistent with the Limited Attention Theory. Econometric tests showed that variables related to low accounting quality, low profitability, and low dividend payout increase the likelihood of a firm being targeted by ACSS. Moreover, the event study confirms that the disclosure of these reports generates significant and persistent negative abnormal returns in the stock prices of target companies. The study concludes that ACSS play a relevant role as private mechanisms of monitoring and fraud detection, thereby contributing to market efficiency. The findings provide practical implications for investment managers, regulators, auditors, and professionals engaged in fraud prevention, by offering evidence of the risk factors that make companies more vulnerable to activism short selling campaigns, as well as identifying techniques and sources of information useful for detecting fraud and other irregularities.
