Ao abordar essa perspectiva de análise, as cidades passam a ser compreendidas a partir daquilo que ela proporciona e a partir daqueles que a experimentam cotidianamente
Association between scientific initiation and success in postgraduate studies
Full text linkThis study investigates the relationship between participation in Scientific Initiation (SI) and admission and success rates in graduate programs at the Federal University of Viçosa (UFV). The research was motivated by the need to understand the factors that influence access and academic continuity, especially in the Brazilian context, where graduate school dropout rates pose a challenge for both students and institutions. Using descriptive statistics and logistic regression techniques, data were obtained through the Federal University of Vic¸osa’s open data portal, and specific data were analyzed using R software. Variables such as age, gender, state of origin, and academic standing were examined, enabling the identification of patterns and trends in student trajectories. It was possible to draw an average profile of UFV students, both at the undergraduate and graduate levels, and to assess the relationship between scientific initiation and graduate studies. The results indicate that participation in scientific initiation has a positive association with admission to graduate studies. Students who participated in scientific initiation during their undergraduate years had a significantly higher rate of academic continuation compared to those who did not participate in this program. The results of this research underscore the importance of institutional policies that encourage scientific initiation, promoting greater academic engagement and contributing to a reduction in dropout rates in graduate programs. The study also contributes to the knowledge base on the relationship between scientific initiation and retention in graduate programs.This study investigates the relationship between participation in Scientific Initiation (SI) and admission and success rates in graduate programs at the Federal University of Viçosa (UFV).

Probabilistic Approach in the Analysis of Extreme Vegetable Prices: An Application to Maximum Potato Prices in the State of São Paulo
Full text linkThe study focuses on the analysis of the marketing of fresh produce in Brazil, especially at the São Paulo Wholesale Market (CEAGESP), with a focus on potatoes. The aim is to understand potato supply in the market and model its maximum prices, identifying the marketing potential at CEAGESP. Extreme price analysis was conducted using the Extreme Value Theory, with monthly data from January 2015 to December 2022. For periods without price records, linear interpolation was performed. The values were subjected to Mann-Kendall and Ljung Box tests to assess the presence of trend and temporal dependence, with all analyses conducted in the R program. The results indicated the absence of trend and dependence in the time series, at a significance level of 1%. The analysis revealed significant variations in potato maximum prices, especially in March and April, months with pronounced fluctuations due to the off-season and the end of the main harvest. In contrast, July and August showed a decrease in the probabilities of high prices suggesting stabilization around R 3,00 durante o início do novo ciclo de plantio. Esses resultados são relevantes para compreender as dinâmicas de preços da batata ao longo dos anos, fornecendo informações cruciais para estratégias de gestão de riscos e decisões de planejamento agrícola e comercial. Em resumo, a análise estatística ofereceu uma visão abrangente das variações sazonais e de preços da batata, essenciais para uma gestão eficiente e planejamento estratégico no setor agrícola
The Transformation of Family Farming Establishments in São Paulo
Full text linkThe participation of family farming in Brazil is crucial for food production, job creation, and sustainable advancement, representing about 77% of the country's agricultural establishments. However, in São Paulo, family farming faces significant challenges. This study proposed using the negative binomial regression model on the data of the evolution of agricultural establishments, both family and non-family, over the period from 1970 to 2017, using data from the Brazilian Institute of Geography and Statistics (IBGE) in the state of São Paulo. The results indicate a sharp decline in the number of family agricultural establishments compared to non-family ones over the analyzed period. Based on the adjusted model, it is predicted that if this declining trend continues, there could be a reduction of up to 96% by 2026 compared to the 2017 figures. This alarming trend highlights the urgent need to adopt measures to support and strengthen family farming in São Paulo, thereby ensuring its sustainability and contribution to food security and regional development.A participação da agricultura familiar no Brasil é crucial para a produção alimentar, a criação de empregos e o avanço sustentável, representando cerca de 77% dos estabelecimentos agrícolas do país. No entanto, em São Paulo, a agricultura familiar enfrenta obstáculos significativos. Este estudo propôs o uso do modelo de regressão binomial negativa dos dados da evolução dos estabelecimentos agrícolas, tanto familiares quanto não familiares, ao longo do período de 1970 a 2017, utilizando dados do Instituto Brasileiro de Geografia e Estatística (IBGE) no estado de São Paulo. Os resultados indicam uma queda acentuada no número de estabelecimentos agrícolas familiares em comparação com os não familiares ao longo do período analisado. Com base no modelo ajustado, prevê-se que, se essa tendência de declínio persistir, até 2026 poderá haver uma redução de até 96% em relação aos números de 2017. Esta tendência preocupante destaca a necessidade urgente de adotar medidas para apoiar e fortalecer a agricultura familiar em São Paulo, garantindo assim sua sustentabilidade e contribuição para a segurança alimentar e o desenvolvimento regional

Sensitivities of Bartlett’s Sphericity Test and the Kaiser-Meyer-Olkin Index on the Adequacy of the Correlation Matrix for Factor Analysis
Full text linkPara a análise de fatores, pressupõe-se que haja relação presente na matriz de correlações entre as
variáveis. Para avaliar a matriz de correlações, o teste de esfericidade de Bartlett e o índice de Kaiser-Meyer-Olkin (KMO) são os métodos mais utilizados. Com o objetivo de avaliar as sensibilidades destes dois métodos,
foram geradas 42 diferentes matrizes com base em quatro variáveis (Y1, Y2, Y3 e Y4). Pelo teste de esfericidadede Bartlett aplicado às hipóteses H0: ρ = I vs. H1: ρ ≠ I, foi obtido o maior tamanho da amostra (n) que nãorejeitou H0 a 5%, a 1%, a 0,5% e a 0,25% de significância. Para o índice KMO, foi obtido apenas o valor n. Deacordo com os resultados, o teste de esfericidade de Bartlett foi mais sensível à correlação r D e menos sensívelao nível de significância α e à correlação rE, para rejeitar a hipótese H0. Além disso, foi notória a sua altadependência do valor n. Assim, o teste de esfericidade de Bartlett é mais conclusivo, não se rejeita H0. QuandoH0 é rejeitada, recomenda-se utilizá-lo em conjunto com outros critérios de avaliação da adequação da análisede fatores, especialmente ao nível de significância α = 0,0025. Já os valores do índice KMO não foraminfluenciados pelos valores de rD e rE. Em média, o seu valor foi de 0,55, independente da matriz R ter sidoadequada ou não para a análise de fatores. Por isso, ele não é recomendado.For factor analysis, it is assumed that there is a relationship present in the correlation matrix betweenthe variables. To evaluate the correlation matrix, Bartlett's test of sphericity and the Kaiser-Meyer-Olkin index(KMO) are the most used methods. In order to evaluate the sensitivities of these two methods, 42 differentmatrices were generated based on four variables (Y1, Y2, Y3 and Y4). Using Bartlett's sphericity test applied tothe hypotheses H0: ρ = I vs. H1: ρ ≠ I, the largest sample size (n) was obtained that did not reject H0 at 5%, at1%, at 0.5% and at 0.25% of significance. For the KMO index, only the n value was obtained. According to theresults, Bartlett's sphericity test was more sensitive to the rD correlation and less sensitive to the significancelevel α and the rE correlation, to reject the H0 hypothesis. Furthermore, its high dependence on the value n wasnotable. Thus, Bartlett's sphericity test is more conclusive, H0 is not rejected. When H0 is rejected, it isrecommended to use it in conjunction with other criteria for evaluating the adequacy of the factor analysis,especially at the significance level α = 0.0025. The values of the KMO index were not influenced by the values ofrD and rE. On average, its value was 0.55, regardless of whether the R matrix was suitable or not for factoranalysis. Therefore, it is not recommended.
