Title: Coleta seletiva em Uberlândia (MG) sob a ótica da Psicologia Ambiental: perspectivas para o fortalecimento da gestão integrada dos resíduos sólidos Abstract: The generation of solid waste has become an increasingly complex and urgent issue. Population growth, coupled with the intensification of economic activity, has increased waste generation, often without the infrastructure required for its proper disposal. The presence of waste in space is not limited to a technical management problem but reflects deeper fractures in the relationship between society and nature, compromising environmental quality, the aesthetics of the landscape, and the symbolic bond between individuals and place. In this context, selective collection constitutes a central component of Integrated Solid Waste Management, although its effectiveness cannot be explained solely by the existence of infrastructure, regulations, or informational campaigns. In the municipality of Uberlândia, Minas Gerais, despite the expansion of the service's territorial coverage, public adherence remains limited, as evidenced by the continued disposal of recyclable waste through conventional waste collection and sanitary landfilling. Based on this observation, the primary objective of this doctoral thesis is to understand the factors that influence public adherence to selective collection in the municipality of Uberlândia in 2024. The research demonstrates that adherence to selective collection is not primarily the result of isolated individual decisions but rather the expression of a person–environment relational system, in which spatial, institutional, educational, and psychological dimensions shape pro-environmental behavior. The methodological procedures included bibliographic, documentary, and field research, using institutional data and statistical information. Thematic maps were produced based on secondary data obtained from official sources using QGIS software, focusing on variables such as service coverage, population density, and waste collection infrastructure. In addition, intensive direct observations and exploratory semi-structured interviews were conducted through a questionnaire with 34 participants selected for their representativeness in the municipal selective collection process from a population of 166 workers involved in the program. The findings reveal a mismatch between the available infrastructure and its effective appropriation by citizens, indicating that low adherence to the service is not primarily explained by a lack of knowledge or information. The strengthening of Environmental Education, by incorporating psychological dimensions related to perception, values, beliefs, norms, attitudes, cognition, and cognitive heuristics, proved to be decisive in shaping pro environmental behavior, thereby promoting greater public adherence to selective collection. Furthermore, factors associated with accessibility, visibility, environmental setting, and other environmental attributes of the service infrastructure, when designed to account for the environmental stimuli that shape individual behavior, also tend to increase the likelihood of public adherence. Therefore, public adherence to selective collection depends on the articulation between the structural conditions of space and the psychological processes associated with person–environment interaction. Accordingly, increasing adherence to selective collection requires strategies that integrate Environmental Education, the reorganization of spatial and institutional contexts, and interventions grounded in the principles of Environmental Psychology. By highlighting the centrality of the person environment relationship in solid waste management, this thesis contributes to advancing discussions on public policies and to building more consistent pathways toward the transformation of mindset.

Title: Compre aqui, bom e barato! As redes e o comércio nas feiras de confecção do estado do Ceará Abstract: Street markets constitute commercial modalities that, even with all the transformations occurring in the forms of merchandise distribution, have survived and gain a relevant role in the economic and social dynamics of the places where they operate. They forge territorialities and go beyond the physical limits of their installation. Given their strong regional visibility, this study focuses on the apparel trade network in Ceará, with particular attention to the José Avelino Cluster in Fortaleza and the open-air markets of8 São Benedito, Ipu, and Aprazível (Sobral). The selection of these sites is justified by the spatial reach of their products, which circulate across neighboring municipalities and adjacent states, thereby consolidating a network of local, regional, and national significance. The dynamics of apparel commerce within these markets operate not merely as trading hubs, but as strategic nodes within an extended commercial network capable of mobilizing commodity flows across Brazil’s four macro-regions. Accordingly, the research examined these dynamics through the analytical lens of geographical trade networks, focusing on the circulation of goods, consumption patterns, and the power relations underpinning the spatial organization and management of these marketplaces. As specific objectives, it sought to: discuss the dynamics of garment fairs from the theoretical perspective of the relationship between commerce and space; analyze the networks and flows of goods and people generated by the garment trade; characterize the economic and social agents who produce the space of the fairs based on commercial and consumption practices; understand the role of Public Authorities, associations, and stallholders in the organization and management of the space of these marketplaces. Methodologically, the theoretical framework relies on an extensive literature review, which provides the foundation for the thesis. A mixed-methods approach—combining quantitative and qualitative procedures—was adopted to identify, measure, and interpret the empirical data. The narratives of key actors—including traders, consumers, and market administrators—were integral to data collection and supported by photographic documentation, both of which contributed substantially to the empirical construction of the thesis. The findings highlight the emergence of a robust apparel supply network originating in the state capital and extending deep into Ceará’s hinterlands, sustaining a commercial system that transcends state borders and reinforces the multi-scalar interconnectedness of urban and regional markets.

O acesso aos serviços de saúde na várzea amazônica

Title: O acesso aos serviços de saúde na várzea amazônica Abstract: In the Amazon region, ways of life are structured in close relationship with nature, shaped by rivers, forests, and climate dynamics, which configure and reconfigure specific territorialities that directly influence the mobility and work of Amazonian populations, as well as their access to health services. Although there have been advances in the Brazilian Unified Health System (SUS), particularly in the Amazon region, territorial inequalities still hinder effective access to the services provided, especially in floodplain areas, where the organization of the healthcare network does not fully correspond to the territorial dimension of nature, shaped by the seasonal dynamics of water levels and climatic conditions. In this context, the present study aims to understand the mobility of peasants in the Amazonian floodplain in accessing health services, considering (im)material territorial dimensions and the routes undertaken across the islands of Paciência, Muratu, Jacurutu, and Paz, in the municipality of Iranduba, Amazonas (AM). The research is grounded in the framework of Health Geography and adopts methodological procedures that combine territorial analysis, the collection of empirical data, and the investigation of socio-environmental and infrastructural conditions that influence access to health services, taking territory as its analytical basis. The results demonstrate that the health territory in the floodplain is dynamic and strongly influenced by the hydroclimatic regime, producing differentiated routes between periods of river flooding and drought, which directly impact the time, cost, and conditions of population mobility. It was observed that, during the flooding season, fluvial access facilitates mobility, whereas during the dry season, travel becomes longer, more fragmented, and more costly, thereby exacerbating situations of vulnerability and health inequities. It was further found that the concentration of services in urban centers, combined with the limited territorial adaptation of public policies, contributes to the fragmentation of access to Primary Health Care (PHC) in the study area. As a contribution, this study proposes territorial health arrangements that are sensitive to the seasonality of the floodplain, grounded in the territorial reorganization of service provision, the expansion of healthcare coverage, and the development of planning strategies adapted to climate change and to the socio-spatial specificities of the Amazon. It is concluded that the planning of health territories in the Amazon requires the incorporation of (im)material dimensions as structuring elements of health territories in floodplain areas, in order to promote greater equity in access to health services and to strengthen the territorialization of the Brazilian Unified Health System (SUS) in contexts of high socio-environmental vulnerability.

Title: Esclerose lateral amiotrófica: caracterização clínica e epidemiológica de pacientes atendidos em um hospital universitário Abstract: Amyotrophic Lateral Sclerosis (ALS) is a rare and progressive neurodegenerative disease, whose clinical, functional, and social impact is exacerbated by the absence of a cure and the limited effectiveness of available treatments. In this context, the present study aimed to analyze the sociodemographic, clinical, and epidemiological profile of ALS patients in the Triângulo Mineiro region of Brazil, with emphasis on the relationship between pesticide exposure and disease incidence, as well as to evaluate the effectiveness of specialized home care. The sample consisted of 70 patients diagnosed with ALS and monitored by the Home Care Service of the Federal University of Uberlândia between 2018 and 2023. The majority of patients were male (58.2%), with a mean age of 60 years, low educational attainment, and household income below two minimum wages. Approximately 23.5% had direct or indirect occupational links to agricultural activities, and 61.8% lived in rural or peri-urban areas. Statistical analysis revealed a significant association between rural occupations and ALS diagnosis (p < 0.0001), suggesting a potential correlation between occupational pesticide exposure and the disease. Data analysis indicated that the predominant ALS form was familial (34%), with limb-onset phenotype in 60% of cases and a mean survival of 38 months after symptom onset. The average diagnostic delay was 21.9 months. Death was the outcome in 63.6% of the cases. The "Melhor em Casa" Home Care Program played a central role in patient care, providing multidisciplinary support and resources such as gastrostomy, oxygen therapy, medication management, and palliative care. The findings highlight the significant role of environmental and occupational factors in ALS incidence and underscore the urgent need for public policies focused on pesticide regulation, rural worker protection, and the expansion of specialized home-based care.
