Autor(es): Duarte, José Roberto Lima Abstract: This study investigates the effects of aggregate shocks on the productive sectors of the Brazilian industry, using a vector autoregressive (VAR) model to capture the dynamic relationships between macroeconomic variables. The analysis is based on data from the IBGE’s Quarterly National Accounts System, which classifies the Brazilian industry into four major sectors: Extractive Industries, Manufacturing Industries, Electricity and Gas Industries, and Construction Industries. This study adopts a Structural Vector Autoregressive (SVAR) approach, imposing long-term restrictions to distinguish supply, demand, and external shocks. Subsequently, the estimated shocks are included as exogenous variables in another model to analyze the impact of aggregate disturbances on sectors through impulse-response functions. The estimated models allow for the assessment of shocks’ impacts according to three types of transmission: total impacts, direct impacts, and indirect impacts. The results reveal marked sectoral heterogeneity, especially in the long run. Demand shocks exhibit transitory effects, except in the Construction sector, a finding consistent with the related literature. In contrast, supply shocks generate permanent impacts in most sectors, with the exception of Electricity and Gas. Finally, external shocks stand out for their large magnitudes, although their effects display different signs across the sectors analyzed.

Autor(es): Lima, José Carlos Souza Abstract: The quality of early childhood education can be expressed through responsive interactions between adults and children and by learning environments, which in turn must be safe, stimulating, and holistic to foster child development (Raikes et al., 2023; Yoshikawa et al., 2013; Maia & Williams, 2005). Enhancing this quality is possible through monitoring (Yoshikawa et al., 2018), requiring the use of instruments for data collection. This work comprises two essays aimed at exploring the reliability of the “Escala de Avaliação dos Ambientes de Aprendizagens dedicados à Primeira Infância” (EAPI), which seeks to measure quality in early childhood education. The first essay seeks to analyze the reliability of the EAPI application in the continuous format of five days of application, through stability (over time), internal consistency (of the instrument), and equivalence (agreement among observers). The second uses a data panel to conduct an analysis of observer characteristics and their impact on the reliability of applicators' responses to the instrument. Previous knowledge of observers about child development and information regarding field data collection were used. It was found that the number of applications does not affect equivalence and stability; however, the number of observers influences reliability. In reapplications, it is ideal to diversify the observer to two or three different individuals, for better coefficients. Internal consistency was negatively affected by continuous applications but indicates stabilizing after four days. Finally, knowledge about child development, experience, and performance in certification contributed positively to reliability, while the weekly application load negatively impacted it.

Autor(es): Dantas, Rayane Costa Abstract: Domestic violence is present in many homes and has emerged as a serious social problem. In this context, the aim of this study is to investigate how Brazilian scientific production on domestic violence has been characterized over the last 20 years. To this end, a bibliometric analysis of thematic axes, constructed from topic modeling (LDA), of publications on domestic violence found in the Scopus database was conducted for two periods, 2005 to 2014 and 2015 to 2024, to investigate temporal evolution. The results were generated using the R software. Three topics were identified in each period, which were labeled as a thematic axis. Thus, the research includes the temporal evolution of the articles, the most frequent terms in each period, the terms with the highest probabilities in each subtopic, the main co-occurrences between the terms, and the most productive universities. Therefore, each topic generated co-authorship networks between universities, countries, and authors, as well as graphs showing the gender distribution of the authors. The results suggest that scientific production on the topic is greater in the more recent period and that the words woman, child, and health have high frequency in the corpus. Furthermore, the LDA identifies topics with representative terms related to violence against women and gender-based violence, intimate partner violence, domestic abuse of children and adolescents, and prevention and intervention programs. It was concluded that USP (University of São Paulo) accounts for the majority of the works. International collaboration reveals, mainly, Brazilian partnerships, which are more comprehensive in recent years and concentrated in the United States and the United Kingdom; however, in the second period, two of the subtopics indicated the existence of strong collaboration with Portugal. It was found that most of the authors' names are female. Therefore, the research gathers information on what is being produced in the literature on domestic violence in each subtopic analyzed and contributes to a better understanding of this scientific field.

It is based on the hypothesis that diabetes is not randomly distributed in the population, but follows systematic gradients across age and socioeconomic position. The empirical strategy combines the estimation of a binary logit model, the calculation of the Erreygers-corrected Concentration Index, and decomposition techniques, including the nonlinear Oaxaca–Blinder decomposition. The results indicate a strong concentration of diabetes among older individuals and a more moderate socioeconomic gradient when ranked by income. Age, hypertension, and obesity are strongly associated with a higher probability of diagnosis, while higher levels of education exhibit a relevant protective effect, even after controlling for income and lifestyle factors. The decomposition analyses suggest that educational differences in diabetes prevalence cannot be fully attributed to observable characteristics included in the model, although the decomposition does not allow precise statistical identification of the relative contribution of explained and unexplained components. Similarly, in the case of racial differences, while disparities in diabetes prevalence are observed across groups, the decomposition suggests that these differences are partly associated with the unequal distribution of socioeconomic characteristics and access to health services, and should therefore be interpreted with caution. Overall, the findings reinforce the interpretation of diabetes as an outcome shaped by social processes accumulated over the life course. The study concludes that effectively addressing diabetes in Brazil requires intersectoral public policies that combine improved access to healthcare with broader efforts to reduce structural inequalities in education.
