This paper analyzes the distribution of political-party affiliations among the defendants implicated in Brazil’s Car Wash Operation. Methodologically, the study compiled the names of all Car Wash Operation defendants and cross-referenced them with official records of political-party membership. The analysis yielded three principal findings. First, the proportion of defendants with political-party affiliations exceeds that observed in the general population. Second, the distribution of party affiliations among defendants mirrors the relative size of the parties, with larger parties associated with a greater number of affiliated defendants. This pattern holds for both ordinary court defendants and individuals with privileged jurisdiction before the Brazilian Supreme Court (the latter being classified as persons under investigation rather than formal defendants). Third, the data indicate that a single jurisdiction, Curitiba, was responsible for the majority of complaints filed against members of the Workers’ Party.

This study aims to map and analyze the current landscape of mobile health applications designed for women's health within the framework of Primary Health Care. The review seeks to provide a comprehensive perspective on the integration of these digital technologies in health promotion and clinical care, offering valuable insights for healthcare professionals, researchers, and developers of innovative health solutions. A literature review was conducted in accordance with PRISMA guidelines, with searches performed across four major databases: PubMed, SciELO, Scopus, and Web of Science. Eligible studies included articles published in Portuguese, English, or Spanish, explicitly focusing on mobile applications for women's health. The selection process involved a two-stage approach: an initial screening of titles and abstracts, followed by an in-depth full-text review of the selected studies. Ultimately, 36 studies were included and categorized based on methodological design, study scope, technological functionalities, target population, and key findings. The results indicate that the analyzed mobile applications predominantly address women's health needs in a fragmented manner, lacking structured integration with public health policies or coordinated programmatic actions within healthcare systems.

The increase in chronic diseases and climate change in recent decades has been driven by food systems that affect both human health and the environment. This study investigated the interrelation between food consumption, obesity, undernutrition, and climate change, aiming to understand how these factors connect within the global syndemic. The methodology used was a scoping review, in which 12 articles were analyzed after an initial search that resulted in 11,208 references. The references were screened using the Rayyan software (Rayyan Systems Inc. (Doha, Qatar), version 1.6.1 and web-based version), removing duplicates and assessing the studies based on eligibility criteria. The articles addressed different aspects, such as the relationship between food consumption, obesity, undernutrition, and climate change, providing data on how food insecurity and socioeconomic conditions influence these conditions. In sequence, we developed a conceptual model to offer a detailed view of the factors affecting the global syndemic, considering the availability of food, its accessibility, stability in supply, and its use in the diet. The model recognizes that climate change affects food consumption both directly and indirectly. Direct effects include the impact of extreme weather events—such as floods and droughts—on the availability, access, quantity, and quality of food. Indirectly, climate change exacerbates socioeconomic vulnerabilities and disrupts food systems in more structural ways, contributing to increased food insecurity. The findings revealed that food insecurity, in turn, can lead to both obesity and undernutrition, particularly among vulnerable populations. There was a scarcity of studies that integrated the relationship between undernutrition, climate change, and food consumption, especially in certain regional contexts such as Latin America. The evidence gathered in the literature and the conceptual model provide a foundation for future research and the development of more effective public policies that integrate food issues, public health, and climate change in a more holistic and interconnected approach.

The Quality Index for School Meal Menus (Índice de Qualidade para Cardápios da Alimentação Escolar – IQCAE) is a tool that considers the nutritional and cultural dimensions of the menu. The IQCAE validation process showed the need to update it according to current resolutions and the planetary health emergency. To review and validate the new version of the IQCAE. This methodological study used a convenience sample of 425 municipalities proportionally distributed across the regions of Brazil, with 2,125 school menus offered from Monday to Friday. The tool was reviewed in two stages: the creation of a group of expert researchers and the analysis of the theoretical framework to define the components of the reviewed index. Criterion validity, structural validity, reliability, and reproducibility were assessed for validation. The IQCAE-R has 14 components, and its criterion validity is supported by moderate agreement between the experts’ evaluation and its application to the menus. Regarding reproducibility, the mean scores of the evaluators showed no difference, showing that the tool provides the same result when applied repeatedly. Internal consistency was verified using the Spearman correlation, which ranged from weak to very strong. Finally, exploratory factor analysis was satisfactory for most items. The IQCAE-R met the validity and reliability criteria for evaluating school menus and incorporates sustainability components, current recommendations, and current PNAE guidelines.

RESUMO O combate à má alimentação em todas as suas formas, que também se expressa na epidemia da obesidade, é uma das prioridades da Agenda 2030 e dos Objetivos de Desenvolvimento Sustentável. Este artigo traz elementos sobre insegurança alimentar no Brasil, a partir de temas relativos ao crescimento populacional, mudanças climáticas, biodiversidade e sistemas alimentares tradicionais e regenerativos; trata também do papel dos movimentos sociais para a garantia do Direito Humano à Alimentação Adequada. O Grupo de Pesquisa em Nutrição e Pobreza, o Saúde Planetária Brasil, e o Centro de Inteligência Artificial (C4AI) - Eixo AgriBio, entendem que a retomada organizada e sistêmica das frentes apontadas neste artigo de posicionamento, pode constituir um caminho para a articulação entre pesquisa, serviço e políticas públicas na direção do combate à fome e às demais manifestações da má alimentação, enquanto problema complexo prioritário para a garantia do bem-estar social.

Profissionais de tecnologia da informação (TI) com competência de gestão e administradores de empresas com conhecimento de TI estão sendo valorizados pelas empresas. Assim, partindo-se da premissa de que alunos de sistemas de informação podem se beneficiar de conhecimentos de administração de empresas, e vice-versa, este artigo apresenta o projeto e a implantação de um Certificado de Estudos Especiais (CEE) interdisciplinar em TI e Negócios. A experiência integrou disciplinas dos cursos de Sistemas de Informação e Administração, oferecidas em diferentes unidades da mesma instituição de ensino superior. De modo geral, a experiência mostrou-se promissora, capaz de exercitar habilidades interprofissionais, cognitivas e metacognitivas, sociais e emocionais dos estudantes, além de promover a integração docente e discente de ambos os cursos envolvidos.

O estudo analisou a relação entre otimismo, ancoragem, excesso de confiança, representatividade, realismo, comunalidade e tempo, com a acurácia na previsão de lucro de analistas. Foram consideradas empresas brasileiras de capital aberto em 2019, aplicando teste de correlação, diferença de média e regressão múltipla. Os resultados indicaram que a acurácia é influenciada negativamente pelo otimismo e positivamente pela ancoragem e comunalidade. Ademais, a incerteza presente na distância entre a previsão emitida e a divulgação do lucro por ação também implica negativamente na acurácia dos analistas. Adicionalmente, constatou-se que o valor justo, lucratividade, emissão de ADRs e setor auto regulamentado, são aspectos relacionados com maior acurácia. Desse modo, a pesquisa contribui com a literatura para reflexão quanto à necessidade de concatenar aspectos comportamentais e temporais aos financeiros, bem como para sinalizar a importância de que os modelos de previsão dos analistas considerem os aspectos comportamentais em suas tecnologias de informação.

Several studies have indicated a type of hierarchical capitalism in Latin America, characterized by the presence of multinational and state corporations, diversified multi-enterprise groups, low-skilled labor, and segmented labor markets. From the perspective of ownership networks, we explore who the owners of large Brazilian corporations are. These networks reveal actors and groups with prominent positions in the structure and ownership of companies. Thus, this article proposes to 1) describe the ownership network of the largest Brazilian corporations; 2) analyze the density, average degree, modularity, and the number of components connected in this network; 3) analyze measures of weighted degree centrality, intermediation, and eigenvector; 4) identify and analyze subgroups in the network, and 5) relate the configuration of the ownership network with hierarchical capitalism in the Brazilian context. The results point to prominent positions of financial shareholders, the Brazilian state (state-owned firms), and groups composed mostly of large multinationals, financial firms, families, and state-owned firms, confirming that the ownership structure is strongly linked to these players.

RESUMO Vários estudos têm apontado para um tipo de capitalismo hierárquico na América Latina, caracterizado pela presença de corporações multinacionais, estatais, grupos multiempresariais diversificados, baixa qualificação da mão de obra e mercados de trabalho segmentados. A partir da perspectiva das redes proprietárias - que revelam atores e grupos com posições proeminentes na estrutura e propriedade das empresas - exploramos quem são os donos das grandes corporações brasileiras. Assim, este artigo propõe: 1) descrever a rede proprietária das maiores corporações brasileiras; 2) analisar a densidade, o grau médio, a modularidade e o número de componentes conectados nessa rede; 3) analisar medidas de centralidade de grau ponderado, intermediação e autovetor; 4) identificar e analisar subgrupos na rede e 5) relacionar a configuração da rede proprietária com o capitalismo hierárquico no contexto brasileiro. Os resultados indicam que acionistas financeiros, o Estado brasileiro (por meio de empresas estatais) e grupos compostos majoritariamente por grandes multinacionais, empresas financeiras, famílias e empresas estatais estão em posições proeminentes, confirmando que a estrutura de propriedade está fortemente atrelada a esses atores.
