bell hooks e Educação Infantil: por uma pedagogia feminista, antirracista e amorosa
(Universidade Federal de São Carlos, 2025-12-15) Nazario, Beatriz da Silva; Marcelino, Giovanna Henrique; http://lattes.cnpq.br/5799491433211576
This thesis analyzes bell hooks' contribution to the field of early childhood education, with special attention to her conception of gender, her critique of structural inequalities, and the transformative potential of her children's books. Based on the intersectional perspective developed by the author, which articulates race, gender, class, and criticism of capitalism, we seek to understand how hooks offers theoretical, political, and pedagogical foundations for thinking about feminist and anti-racist education from early childhood. The literature review seeks to understand the concept of gender and the relationship between gender inequality and education, the history of childhood and early childhood education in Brazil, situating the child as a social, political, and cultural individual. Then, we discuss the centrality of childhood in hooks' work, highlighting how her writing, marked by the ethics of love, provides an engaged pedagogy focused on freedom. It is expected that the reflections will contribute to expanding the debate on the need of a feminist, anti-racist, and loving pedagogy in early childhood education.

The exponential growth of the older adult population and the increasing burden of cognitive health–related problems demand the development and implementation of effective strategies to promote healthy, autonomous, and active aging. In this context, dance has emerged as a potential intervention to address cognitive health challenges and mitigate impairments that may accompany the aging process, acting as a modifiable factor associated with dementia risk. Therefore, it is essential to investigate approaches that promote physical, cognitive, and emotional health in older adults, contributing to improvements in quality of life and overall well-being. Objective: To evaluate the effects of a three-month dance-based intervention in older women, considering anthropometric, physical, metabolic, cognitive, and psychological outcomes. Methods: This was a pre–post intervention study with a single dance intervention group (n = 34). Physical assessments, body composition analyses, questionnaires assessing cognitive status and emotional well-being, and measurements of biochemical parameters and ADAM10 levels were conducted. Heart rate was monitored during the sessions to ensure maintenance of moderate-intensity exercise. Intervention effects were analyzed using linear mixed-effects models. Results: Body composition analysis indicated a trend toward reduced fat mass (–3.2%; p = 0.063; d = 0.065). Significant improvements were observed in metabolic parameters, including reductions in triglycerides (–16.1%; p = 0.012; d = 0.460) and fasting glucose (–8.2%; p < 0.001; d = 0.780). Cognitive performance improved significantly, with increases in immediate memory (+11.1%; p < 0.001; d = 0.767) and delayed memory (+31.7%; p < 0.001; d = 0.761), as well as a trend toward higher Mini-Mental State Examination scores (+3.1%; p = 0.062; d = 0.102). Depressive symptoms decreased significantly (–30.1%; p = 0.010; d = 0.48). Conclusion: These findings suggest that dance may be incorporated as an effective non-pharmacological intervention to promote metabolic and cognitive health in older women, demonstrating potential to reduce modifiable factors associated with the risk of dementia development.
Vidas em movimento entre muros e pontes: ócio e processos educativos na vida cotidiana de povos indígenas Warao e Pemón refugiados
(Universidade Federal de São Carlos, 2025-11-24) Silva, Robson Amaral da; Montrone, Aida Victoria Garcia; http://lattes.cnpq.br/9011731777978672; http://lattes.cnpq.br/1240102883590524; https://orcid.org/0000-0002-4764-4597; Montrone, Aida Victoria Garcia; Gonçalves Junior, Luiz; Corrêa, Denise Aparecida; Lemos, Fábio Ricardo Mizuno; Nolasco, Carlos Manuel Simões; http://lattes.cnpq.br/901173177797867; http://lattes.cnpq.br/1324174147128430; http://lattes.cnpq.br/7114759404153218; http://lattes.cnpq.br/9720009502941255; http://lattes.cnpq.br/8193722803658213
Human mobility is not a new phenomenon in history and is directly related to the very process of human development over time. Movement between territories is an intentional activity that enables people to seek to satisfy material and symbolic needs when they recognize that they can no longer meet them in their places of origin and/or residence. Currently, there has been an increase in population movements between and towards countries in the global South, with Venezuelan migration in Latin America, especially to Brazil, standing out. The enjoyment of leisure by migrants and refugees in the context of emergency shelters is an aspect that has received little attention in scientific studies in our region. The overall objective of this thesis was to understand the meaning attributed to the social practice of leisure in everyday life by indigenous refugees from the Warao and Pemón peoples, as well as to describe and analyze the educational processes resulting from the enjoyment of leisure in emergency shelters in the city of Boa Vista/RR. Ten indigenous refugees from these peoples participated in the study, eight men (one Warao and seven Pemón) and two women (one Warao and one Pemón), adults who had been living for more than thirty days in the Waraotuma a Tuaranoko shelter, where the research was conducted. The data collection instruments used were semi-structured interviews, field diaries, and photographic records, the latter used as illustrative auxiliary instruments. Data analysis was based on a hermeneutic-dialectical approach, with the construction of thematic categories organized from the units of meaning identified in the interviews. The presentation of the data was based on information systematized according to the following thematic categories: A) Coexistence as a vital dimension in the daily lives of indigenous refugees; B) The meanings of leisure and its relationship with time and pleasure; C) Leisure activities experienced in the context of the shelter. The activities observed in the shelter and mentioned in the participants' statements, such as rest, sports, games, conversations, courses, crafts, music, painting, volunteer work, and religious practices, demonstrate that leisure is experienced in a relational, collective, and creative way, often associated with coexistence, learning, and hope. In these practices, leisure is not reduced to inactivity, but is configured as a time for doing and sharing. Whether in the Athletics in Motion project, in handicrafts, or in family and community interactions, leisure emerges as an instrument of integration and subjective strengthening, enabling indigenous refugees to attribute new meanings to their life trajectories, without disregarding the daily hardships of the refugee regime. The thesis is defended that leisure constitutes a social practice that challenges the logic of immediate survival, affirming the humanity of individuals and their ability to act, learn, teach, and reinvent themselves in contexts of forced displacement. Thus, leisure reveals itself as time and space in which educational processes are triggered, composing the process of (re)existence in the daily lives of Warao and Pemón indigenous people in refugee situations.
Livraria “independente” na era digital: um estudo de caso da Barsa Livros como rugosidade
(Universidade Federal de São Carlos, 2025-10-06) Bottaro, Thiago Barsalobres; Salgado, Luciana Salazar; http://lattes.cnpq.br/5206927424265495; http://lattes.cnpq.br/2352417925771177; Rocha, Rejane Cristina; Muniz Jr., José de Souza; http://lattes.cnpq.br/5669300635333699; http://lattes.cnpq.br/3115553144573692
In order to formulate its basic hypothesis, this research starts from the following question: does Barsa Livros, an independent bookstore, present itself as an element of friction [rugosidade] within the dynamics of vertical and horizontal relationships of the social organization? Barsa Livros is an independent bookstore in Ribeirão Preto, state of São Paulo, Brazil. It began its activities in 2020, initially operating digitally and with a sales system based on orders. As it developed, it adopted a hybrid approach: dealing with printed books and building its inventory; participating in fairs held in various cultural spaces; and, subsequently, also establishing a physical location, where its activities now take place and where its entire collection is housed. Through a case study, we propose to analyze the publishing market – notably the bookselling sector – in its current historical particularity, with the presence of digital technology and the power exerted by the use of information, presented within the empirical framework of John B. Thompson (2021) and through Bourdieu's (2018) field theory, in order to define the publishing and bookselling field and position the studied bookstore within it. Furthermore, in light of José De Souza Muniz Júnior's thesis (2016), we will study the position of "independent" within this publishing field, as well as the polysemy of the term and its possible characteristics in order to understand the possibility of Barsa Livros presenting itself as an independent bookstore in this field. Subsequently, using Milton Santos' geographical theory (2023), the dynamics of verticalities and horizontalities that compose the banal space will be analyzed in order to verify whether Barsa Livros presents itself as an element of friction within it. Finally, we will test the hypothesis that this bookstore functions as a medium and materializes this friction in space through the methodology of materialized organization and organized matter (OM/MO) as seen in Régis Debray (2000), in addition to analyzing the bookstore's collection as a technema: a technique that makes it point to reticular and/or contiguous organizations, as well as, in its double-body, relate to hegemonic and/or popular sensibilities (Santos, 2022).
Segmentação de múltiplas patologias em ressonância magnética da coluna lombar: uma abordagem comparativa de aprendizado profundo
(Universidade Federal de São Carlos, 2025-10-29) Leite Junior, Claudio Luiz; Almeida Junior, Jurandy Gomes DE; http://lattes.cnpq.br/4495269939725770; https://orcid.org/0000-0002-4998-6996; http://lattes.cnpq.br/8623721713277640; https://orcid.org/0009-0001-2405-0075; Comin, Cesar Henrique; Cappabianco , Fabio Augusto Menocci; http://lattes.cnpq.br/9563440403120931; http://lattes.cnpq.br/7438076121387151; https://orcid.org/0000-0003-1207-4982; https://orcid.org/0000-0002-2139-7938
Low back pain is a leading cause of disability worldwide, and Magnetic Resonance Imaging (MRI) of the lumbar spine is fundamental for its diagnosis. However, the manual analysis of these images is a time-consuming and subjective process, and existing computational methods are often limited to a single pathology or rely on complex, multi-stage pipelines. A central challenge, not yet fully addressed, is the simultaneous occurrence of multiple pathologies in the same anatomical structure—a common clinical scenario that current models fail to model effectively. This dissertation addresses this gap by proposing and validating a robust methodology for the automated segmentation of multiple co-existing pathologies in lumbar intervertebral discs. The work was structured in two complementary phases. The first established the methodological underpinnings of this research. It consisted of a rigorous empirical study evaluating five deep learning architectures and four loss functions to determine the most effective approaches for the fundamental task of segmenting the vertebrae and intervertebral discs. This step ensured that the subsequent investigation into pathologies was built upon a robust and validated base. The second phase, the main contribution of this work, systematically investigated three distinct strategies for multi-pathology segmentation: (i) binary class segmentation, a baseline that treats each pathology independently; (ii) multi-class segmentation, mapping 70 disease combinations to unique classes (non-overlapping masks); and (iii) multi-label segmentation, which uses binary channels to explicitly model the coexistence of multiple diagnoses (overlapping masks). Our results, derived from over 200 training pipelines, demonstrate that the multi-label approach, especially when implemented with the V-Net and Swin UNETR architectures, achieves diagnostic accuracy comparable to the baseline while offering significantly superior computational efficiency. By developing a unified framework that integrates the precise spatial localization of symptomatic areas with the classification of multiple concurrent diseases, this work establishes a practical and efficient guideline for future research and clinical applications in the automated diagnosis of spinal pathologies.
