Rhythmic gymnastics is an Olympic sport that, by demanding high physical and aesthetic performance, places intense pressure on athletes’ mental health, potentially leading to risk behaviors. In this context, emotional intelligence emerges as a crucial factor for health. This study aimed to investigate the influence of emotional intelligence on eating behavior and body image among rhythmic gymnasts. The research employed a cross-sectional, descriptive, and mixed-methods design. The sample consisted of 37 athletes from states in Northeastern Brazil (mean age = 19.9 ± 1.83 years), who responded to the Schutte Self-Report Emotional Intelligence Test (SSEIT), the Three-Factor Eating Questionnaire (TFEQ-R21), and the Body Shape Questionnaire (BSQ-34). Five athletes participated in semi-structured interviews, analyzed through Bardin’s Content Analysis technique. Quantitative analyses were performed using Jamovi software and relied exclusively on descriptive statistics for sample characterization. In the descriptive results, approximately one-third of the athletes reported some degree of body dissatisfaction (32.4%), while 67.6% reported no dissatisfaction. The median (IQR) scores of the TFEQ-R21 domains were: Cognitive Restraint 44.4 (33.3 – 55.5); Uncontrolled Eating 33.3 (18.5 – 48.1); Emotional Eating 27.8 (16.7 – 55.5). The SSEIT presented a median of 101 (95.0 – 106). Additionally, in the characterization, 75.7% reported having experienced negative comments about their appearance, and 81.1% perceived aesthetic pressure within the sport. The qualitative analysis deepened these findings, revealing that the pressure to achieve an ideal body type (thin and long-limbed) is internalized and generates social comparison, dissatisfaction, and body image distortion. External pressure, exerted by coaches and judges, was manifested through body shaming and rituals such as weigh-ins, which triggered risk behaviors. Emotional states were shown to directly influence eating behavior, with anxiety acting both as a trigger for excessive eating and for appetite suppression. The qualitative narratives suggest that difficulty in emotional regulation, mediated by the intense aesthetic pressure of the sport, is a central factor contributing to the development of risky eating behaviors and body dissatisfaction among rhythmic gymnasts.

Although the federative pact has sought to guarantee autonomy to subnational entities, in Brazil a top-down process of public policy implementation still prevails, often disregarding the municipalities’ level of preparedness. In this context, considering the requirements of Law No. 14,133/2021 for the adoption of an open data model in the management of public procurement and contracting procedures, the objective of this research was to analyze the challenges faced by the municipality of Campo Belo–MG in implementing the National Public Procurement Portal (PNCP), seeking to understand the main elements of state capacity—within its technicaladministrative, fiscal, and political-relational dimensions—that must be considered in this process. More specifically, the study aims to describe how the PNCP implementation process has unfolded in Campo Belo–MG; to identify, from the perspective of local managers, the main factors that either hinder or facilitate the implementation of the PNCP in the municipality; and to assess the municipality’s level of preparedness in terms of technical-administrative, fiscal, and political-relational capacities for the implementation process. This research is a descriptive and exploratory case study that employed document analysis, participant observation, and semistructured interviews as data collection instruments. After content analysis, the results revealed that, from a technical-administrative standpoint, the municipality has qualified and proactive civil servants whose technical skills, experience, training, and level of autonomy are adequate for handling the demands of the new Public Procurement Law (NLLC). However, technological challenges and shortcomings in the internal management system’s support still hinder the full operationalization of the PNCP. Regarding the political-relational dimension, inconsistencies were detected in data entry on the Portal and a lack of integration between the internal system and technical-legal recommendations, which resulted in delays in data publication. Accessibility issues were also reported, particularly with the use of information filters, a functionality perceived by public servants as confusing. Finally, from a fiscal perspective, it was found that the increase in municipal revenues was not proportional to the investment in training and technological support during the legal transition period. In summary, although the municipality has a qualified and experienced technical staff, this alone is not sufficient. Investment in capacity building and technological infrastructure does not depend solely on revenue growth. This leads to the conclusion that the implementation of the Portal still requires the strengthening of local state capacities and a more coordinated federative action to achieve the intended goals of transparency and modernization. Although the Brazilian federative pact seeks to ensure autonomy for subnational entities, the predominantly vertical form of policy implementation still poses challenges to the effectiveness of municipal actions, especially in light of the demands introduced by Law No. 14,133/2021.

This study aimed to identify iceberg lettuce cultivars with greater adaptability and production stability under summer conditions in the macro-regions of Sorocaba/SP and Mogi das Cruzes/SP. A total of 8 experiments were conducted, 4 in Sorocaba/SP region and 4 in Mogi das Cruzes/SP region, each one considered a distinct growing environment. All trials were conducted by commercial growers specialized in cultivation of iceberg lettuce. The trials were transplanted between October and December 2024 and evaluated between November 2024 and February 2025. Seven varieties of iceberg lettuce were used, five standard commercial and two new varieties developed by Enza Zaden company. The experimental design used was a randomized complete block design with 3 replications. The following parameters were evaluated: tassel size, head weight, percentage of marketable plants and disease tolerance. These parameters were subjected to adaptability and stability analysis using the Annicchiarico method. Of the commercial genotypes, COM. 03 stood out positively in relation to head weight and disease tolerance for all environments and favorable environments, while COM. 02 stood out negatively in relation to all parameters. Genotype EXP. 01 showed good results, mainly in unfavorable environments, for head weight and percentage of marketable plants. Finally, material EXP. 02 showed the best results considering tassel size, percentage of marketable plants and disease tolerance, considering favorable and unfavorable environments, thus having greater adaptability and stability among all genotypes under these growing conditions and with greater potential for commercial release.

This is a qualitative master's research project that aimed to investigate the production of meanings about the Brazilian Monetary System by a class of 20 fourth-grade elementary school students when they were involved in problem-solving practices and contexts. The researcher (a licensed Pedagogy professional) partnered with a fourth-grade classroom teacher, as the researcher was not yet working in a classroom. Data was collected from October 2 to October 6, 2023, during which 10 classes, each lasting 50 minutes, were conducted (two classes per day). Data was collected through audio and video recordings, students' written work, and the researcher's field diary. Based on this, the intention was to answer the following research question: What meanings about the Brazilian Monetary System are produced by fourth-grade elementary school students when they are involved in a practice mediated by problematizations? And to achieve the following general objective: to investigate evidence of students' production of meanings about the Brazilian monetary system when engaged in a problematizing practice. To achieve this general objective, the following specific objectives were proposed: to understand the movement and processes of producing meanings about the Brazilian Monetary System; to identify the arguments and strategies used by students in Problem Solving; to reflect on the process of becoming a teacher-researcher; and to propose an educational product about the Brazilian Monetary System through the methodological approach of Problem Solving. For data analysis, microgenetic analysis and the historical-cultural perspective were used, drawing on the works of Lev S. Vygotsky and other researchers who follow his line of thought. Two units of analysis were defined: the production of meanings about the Brazilian Monetary System, and the processes of becoming a teacher and becoming a researcher. Through the analysis, it was possible to perceive evidence of the students' meaning-making when they were involved in a problematized practice about the Brazilian Monetary System, based on the strategies and arguments produced during moments of interaction and the students' written work, as well as the production of meanings about teaching by the teacher-researcher.
