The concept of intersectionality examines how multiple and interdependent forms of oppression manifest among marginalized social groups, considering their social markers. This study aims to analyze intersectionality in the labor market, with a critical focus on the interactions between race, gender, and class as structuring axes of inequality. An integrative literature review was conducted, encompassing an in-depth analysis of 140 articles addressing intersectionality in the labor context. The findings reveal a persistent conceptual fragmentation of intersectionality and a dilution of critical debates within labor market research. Empirical evidence consistently shows that women and racialized groups face enduring structural barriers, including wage gaps, occupational segregation, and limited access to leadership positions. Moreover, these inequalities are often obscured or reduced to superficial diversity and inclusion initiatives rather than being addressed as systemic issues. The study emphasizes the importance of committed and critical intersectional approaches to understanding and addressing systemic inequalities in the labor market, highlighting theoretical and epistemological gaps that must be addressed to advance emancipatory practices and policies that directly confront structural racism, patriarchy, and class-based exploitation. The study contributes theoretically by deepening the application of intersectionality in the labor market and by identifying conceptual and epistemological gaps in the literature. Empirically, it provides practical guidance for organizations to transform diversity initiatives into strategic and inclusive actions, integrating multiple social identities into management policies and practices.
O artigo analisa como fatores pessoais, institucionais e relacionais influenciam o comportamento dos burocratas de nível de rua na implementação do Pronaf, com foco no acesso das mulheres rurais do Vale do Rio Pardo (RS). A pesquisa qualitativa, baseada em estudo de caso, utilizou entrevistas com agentes implementadores e beneficiárias, além de análise documental e observação direta. Os resultados indicam que crenças pessoais, limitações institucionais e relações interpessoais condicionam o processo, gerando barreiras burocráticas e culturais que restringem o acesso feminino. Conclui-se que, embora o Pronaf promova inclusão produtiva, sua eficácia depende da postura dos agentes, da capacitação contínua e da articulação com organizações locais, evidenciando que as relações na implementação podem ampliar ou reduzir desigualdades de gênero.
INTRODUCTION & AIMS: People with multiple myeloma (MM) experience the lowest health-related quality of life (HRQoL) of all cancer populations. This study aimed to explore the short- and long-term effects of a 12-week individualised exercise intervention on HRQoL, MM symptoms, pain, fatigue, neuromuscular strength, and exploratory plasma omics in people with MM. METHODS: People with MM were randomised to exercise (EX) or wait-list control (CON). The 12-week individualised program included twice-weekly sessions supervised by an AEP, with one additional home-based session prescribed per week. Each 1h session consisted of HIIT, moderate-to-hard resistance and bone loading exercises. Outcomes were assessed before, immediately and 6- and 12-months following the program using validated surveys (EORTC QLQ-C30 with MY20 module, FACT-BP, FACIT-F), cardiopulmonary exercise testing, and dynamometry. Plasma omics (metabolomics, proteomics and extracellular vesicles (EV)) were analysed to explore potential biological mediators. RESULTS: Participants with MM (n=60; mean age 65±9 years; 78% male) presented with lytic lesions (78%) and other skeletal complications (13%; back pain, osteoporosis, osteoarthritis). The EX group experienced increases in HRQoL (EORTC QLQ-C30 summary score: +6.3, 95%CI 0.8, 11.9, p=0.03), mediated through improved MM symptoms (EORTC QLQ-MY20: -7.4, 95%CI -15.2, 0.5, p=0.07), bone pain (FACT-BP: +4.4, 95%CI 0.5, 8.3, p=0.03) and cardiorespiratory fitness (V̇O2peak: +3.1, 95%CI 1.4, 4.8, p=0.001) compared to CON; improvements were mostly maintained at follow-up (12 months). Exploratory plasma and plasma EV omics revealed potential biological mediators e.g. increasing primary bile acid biosynthesis pathway in bone pain improvement. No between-group differences (p>0.05) were observed in general pain, fatigue, or neuromuscular strength. CONCLUSION: A 12-week individualised exercise intervention was effective at improving HRQoL, MM symptoms, bone pain and cardiorespiratory fitness, with potential biological mediators identified. The results support the inclusion of exercise as part of standard care to improve the quality of life and health of people with MM.
This study evaluated the cultivation of Euglena gracilis in real urban wastewater as a strategy for organic matter removal, carbon capture, and biomass valorization. Cultivation was conducted at laboratory and pilot scales using different proportions of urban wastewater and a mineral nutrient medium as control. E. gracilis successfully adapted to the wastewater from a university wastewater treatment plant, showing growth kinetics at pilot scale comparable to laboratory-scale systems. High removal efficiencies were achieved for chemical oxygen demand (up to 98.0%) and ammoniacal nitrogen (up to 91.6%), demonstrating the potential of this organism for organic load reduction. Cultivation in undiluted wastewater enhanced carbon incorporation into the biomass, reaching values above 43%, indicating strong carbon assimilation under mixotrophic conditions. The biochemical composition of the biomass varied according to the culture medium, with a clear metabolic shift from protein-rich biomass in mineral medium to carbohydrate accumulation (up to 40.8%) in wastewater-based cultures. These results demonstrate the feasibility of integrating E. gracilis cultivation into urban wastewater systems at pilot scale, combining organic matter removal with carbon capture and the generation of biomass with biotechnological potential.
Rita Lee (1947-2023) eternizou-se na história da música brasileira, sendo conhecida como a Rainha do Rock. Lutando pela conquista de seu espaço nesse meio que, até então, era predominantemente masculino, a cantora e compositora, que embora não se declarasse feminista, abriu caminhos para que outras mulheres também pudessem construir sua trajetória no rock nacional. Além de ser a autora de letras carregadas de ideais de libertação feminina, que questionam estereótipos de gênero e confrontam padrões morais, também manifestou sua resistência à subordinação da mulher em suas duas autobiografias, Rita Lee: uma autobiografia (2016) e Rita Lee: outra autobiografia (2023). A partir dessas duas autonarrativas, este trabalho tem como objetivo compreender como a cantora mostrou-se subversiva no exercício de diferentes papéis de gênero e de que forma isso reflete na sua escrita de si. Para tanto, foi realizada uma pesquisa bibliográfica, apoiada nas contribuições de autoras como Lígia Maria Leite Pereira (2000), Sandra Maia Farias Vasconcelos e Maria Neurielli Figueiredo Cardoso (2009), que abordam o gênero autobiografia; e no tangente às questões do feminino, tomamos como base as reflexões de Elaine Showalter (1994), Elódia Xavier (2021), Joan Scott (2016), Joan Tronto (1997), Simone de Beauvoir (1970) e Teresa de Lauretis (1994). O estudo mostrou que a escrita de Rita Lee não apenas desafia normas institucionais e sociais, mas também funciona como uma tecnologia de gênero, viabilizando reflexões sobre a emancipação feminina.
