(Universidade Federal de São Carlos, 2025-11-24) Uguetto, Rafaela Camargo; Pereira, Gustavo das Graças; https://lattes.cnpq.br/6055750211001915; https://lattes.cnpq.br/4151823892942798
Olive oil production in Brazil, although a relatively recent activity, is highly promising and underscores the need for studies that encompass the entire production chain, from cultivation and processing to quality control of marketed products. In this context, the present study aimed to evaluate selected quality parameters and the sensory acceptance of olive oils produced in Brazil, in comparison with a commercial imported olive oil. The oils were characterized in terms of free fatty acid content, peroxide value, specific extinction, oxidation resistance, and chlorophyll content. The same samples were also subjected to a sensory acceptance test evaluating flavor, aroma, color, and overall acceptance. In addition, this work sought to conduct a survey through an electronic questionnaire to characterize the national olive oil production chain. The results showed that all samples met the legal requirements. Brazilian olive oils exhibited higher chlorophyll content, reflected in their greener coloration, and greater resistance to oxidation at room temperature. On the other hand, the imported olive oil demonstrated higher sensory acceptance in terms of flavor and overall acceptance. Regarding production chain insights, producers most frequently reported the Arbequina, Koroneike, and Arbosana cultivars as the primary raw materials used for olive oil production in Brazil. They also indicated that their 2022 production volume was generally between 500 and 6,000 L, despite having production capacity exceeding current output. The producers expressed optimism about the Brazilian olive oil market, while also highlighting the main challenges faced by the sector. Additionally, the survey enabled the identification of the producers’ principal demands concerning research needs and improvements in the field. Overall, the findings provide an upto-date perspective on the Brazilian olive oil production chain and demonstrate that, although national olive oils comply with regulatory quality standards, they were less accepted sensorially when compared to the imported product.
Antropologia da alimentação: a construção de costumes e hábitos alimentares na região do Sudoeste Paulista
(Universidade Federal de São Carlos, 2025-11-24) D’Angelo, Isabela De Carvalho; Duval, Henrique Carmona; https://lattes.cnpq.br/1127516712972199
El presente trabajo se sitúa en la confluencia de la antropología de la alimentación, campo que comprende la alimentación como un fenómeno complejo, capaz de revelar estructuras sociales, sistemas simbólicos y trayectorias del individuo. Más que atender a una necesidad fisiológica, el acto de alimentarse manifiesta una red de significados culturales, afectivos e históricos que moldean y son moldeados por las experiencias humanas. La alimentación lleva, así, marcas de la memoria, la ancestralidad y la vida cotidiana, funcionando como una lente privilegiada para comprender dinámicas sociales e identidades colectivas. Para investigar tales dimensiones, este trabajo empleó la metodología de bola de nieve en el territorio del Sudoeste Paulista, una estrategia que permitió alcanzar interlocutores con vivencias diversas, ampliando la percepción sobre prácticas y hábitos alimentarios en la región. Las entrevistas presenciales, realizadas con apertura dialógica y acompañadas de observaciones y anotaciones sistemáticas, hicieron posible mapear distinciones entre los conceptos de “comida” y “alimento”, así como captar experiencias, afectos, memorias y significados atribuidos al acto de comer. A partir de este conjunto de relatos, surgió un panorama rico y plural, revelador de la profundidad que la alimentación asume en la construcción social local. La alimentación, entendida como un entrelazamiento entre cultura, religión, política, cotidianidad y afecto, se presenta aquí como un elemento fundamental para la comprensión de las identidades alimentarias del Sudoeste Paulista. Las prácticas culinarias y los saberes transmitidos entre generaciones asumen un papel que sobrepasa la función nutricional, configurándose como rituales, formas de pertenencia e instrumentos de reafirmación cultural. La comida aparece, así, como símbolo y lenguaje, en tanto expresa valores, organiza relaciones y delimita vínculos comunitarios y espirituales. Al mismo tiempo, esos mismos hábitos están en constante transformación, tensionados por las relaciones entre individuo y sociedad, por los distintos estatus sociales y por las experiencias afectivas que componen a cada sujeto. El estudio también analizó la presencia creciente de la globalización y sus desdoblamientos sobre las prácticas alimentarias de la región. Se observó que la expansión de productos industrializados, la estandarización de preferencias alimentarias y la demanda por soluciones rápidas introducen desafíos significativos al mantenimiento de la diversidad culinaria local. La facilidad de acceso a alimentos listos y la difusión de modelos alimentarios globalizados oprimen tradiciones ancestrales y modos de preparación transmitidos en el ámbito familiar y comunitario. En síntesis, la alimentación se revela como un vasto tapiz compuesto por tradiciones, memorias, saberes y prácticas que definen y reflejan a las comunidades del Sudoeste Paulista. Al explorar estas capas, este estudio destaca la potencia de la antropología de la alimentación para iluminar procesos sociales más amplios, reafirmando la comida como un elemento indispensable para comprender los modos de vivir, sentir y significar el mundo.
História e ficção para jovens leitores: a metaficção historiográfica em "O poeta do exílio"
(Universidade Federal de São Carlos, 2025-11-24) Silva, Amanda Mota da; Bignotto, Cilza Carla; https://lattes.cnpq.br/0782750059258019; https://orcid.org/0000-0001-8295-4251; https://lattes.cnpq.br/5719159019022384
En las últimas décadas, se observa un notable crecimiento en la producción de novelas históricas, cuyas características se distancian de aquellas que marcaron el género inaugurado por Walter Scott en el siglo XIX. Estas obras, con frecuencia, revisitan el pasado con una mirada crítica, cuestionando la objetividad histórica y problematizando las formas tradicionales de representación. Ante este panorama, diversos investigadores, en Brasil y en el exterior, se han dedicado a indagar si estas narrativas contemporáneas derivan formalmente del modelo decimonónico o si se configuran como un nuevo género literario. Sin embargo, una parte significativa de esta producción, las novelas históricas destinadas al público infantil y juvenil, sigue siendo poco explorada por los estudios académicos, a pesar de su potencial para articular conocimiento histórico, formación lectora y reflexión crítica sobre el objeto literario. En este contexto, este Trabajo de Fin de Grado (TFG) tiene como objetivo analizar la novela O Poeta do Exílio, de Marisa Lajolo, investigando de qué manera su construcción narrativa dialoga con las prácticas de la ficción histórica contemporánea, especialmente en lo que se refiere a las aproximaciones a la metaficción historiográfica, tal como la concibe Linda Hutcheon. Para complementar el análisis, se considera también la biografía A Vida de Gonçalves Dias, de Lúcia Miguel Pereira, con el propósito de examinar las diferencias estructurales entre ambas obras y evidenciar cómo la narrativa ficcional se distingue de la narrativa histórica, resaltando sus especificidades. Se busca, así, comprender de qué manera la novela moviliza procedimientos de reescritura y problematización de la Historia, tensionando las fronteras entre hecho y ficción, memoria e imaginación. Partiendo de esta reflexión, se pretende contribuir a la ampliación del debate sobre la literatura infantil y juvenil de carácter histórico, evidenciando su relevancia estética, cultural y formativa en el contexto de la producción literaria brasileña contemporánea, así como su papel en la construcción de una conciencia histórica crítica entre los jóvenes lectores.
Educação ambiental como instrumento de ensino sobre mudanças climáticas por meio de jogos ambientais
(Universidade Federal de São Carlos, 2025-11-24) Pimenta, Daniela; Neves, Anne Alessandra Cardoso; https://lattes.cnpq.br/5825341428803511
The present study consisted in practical analysis of the use by educational games as a tool for environmental education. The research was carried out with fourth-grade students from the municipal school system in Votorantim/SP. For this purpose, an environmental game on climate change was developed, addressing topics such as greenhouse effect, causes and consequences of climate change, and possible mitigation strategies. In addition to playful activity, the students answered a written questionnaire, allowing for evaluation of their understanding about topics presented. The results showed significant improvements in learning, confirming the effectiveness of educational games as a resource to promote awareness and the development of values related to sustainability and fight against climate change.
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; https://lattes.cnpq.br/9011731777978672; https://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; https://lattes.cnpq.br/901173177797867; https://lattes.cnpq.br/1324174147128430; https://lattes.cnpq.br/7114759404153218; https://lattes.cnpq.br/9720009502941255; https://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.
Investigating the ground-state and ionization processes of hydrogen peroxide dimers using sequentially combined theoretical approaches
(Universidade Federal de São Carlos, 2025-11-24) Santos, José Luiz Felix; Peterson, Kirk Arnold; Souza, Gabriel Luiz Cruz de; https://lattes.cnpq.br/2951756857186266; https://lattes.cnpq.br/3442700129094678; https://lattes.cnpq.br/2821352329397835; https://orcid.org/0000-0003-1562-5233; https://orcid.org/0000-0003-4901-3235; https://orcid.org/0000-0002-2192-7345
We present a study of the structures and ionization energies (IEs) of a series of conformations of hydrogen peroxide (H2O2) dimers. Ground-state properties were computed using the coupled-cluster with single, double, and perturbative triple excitations, CCSD(T), method with large correlation-consistent basis sets, while the ten lowest-lying IEs of the H2O2 dimer conformations were determined through the use of the equationof- motion ionization potential coupled-cluster with single and double excitations method (EOMIP-CCSD) combined with correlation-consistent basis sets, extrapolation to the complete basis set limit, and consideration of core-correlation effects. All of the stable conformations were determined to be within 10 kJ/mol of the most stable structure (conformation I). The first IE of conformation I was determined to be 11.72 eV, while the corresponding value for conformation V was calculated as 11.58 eV. This difference (which was also noticed for other low-lying IEs and conformations) may be helpful for the assignments of experimental results. Given that the H2O2 clusters were first isolated through the use of beam experiments in the recent years, it is expected that the present work can call the attention of the community. In addition, the use of the combined theoretical approaches employed regarding the selection of the relevant conformations and the exploration of the corresponding ionization processes for the molecular clusters may present an initial guide for researchers venturing into the field.
Fim iminente de um bioma? O avanço das queimadas no Pantanal brasileiro em um cenário de crise climática global
(Universidade Federal de São Carlos, 2025-11-24) Silva, Amanda Teles da; Sanches, Alexandra; https://lattes.cnpq.br/4999886032379825; https://orcid.org/0000-0002-0349-9228; https://lattes.cnpq.br/3212910963358145
The Pantanal has been subjected to increasing anthropogenic pressures, further exacerbated by extreme events driven by human activity. Since 2020, the occurrence of severe and recurrent fires has heightened concerns regarding environmental impacts and the implications for the conservation of the biome. This study aimed to analyze, based on the available literature, the context and effects of wildfires in the Brazilian Pantanal within a scenario of global climate crisis, identifying their main consequences and the future prospects for conservation.The study was conducted through a bibliographic review encompassing scientific articles, technical reports, official documents, and governmental and academic databases. The results indicate that the combination of more severe droughts, climate change, land-use transformations, and the expansion of human activities has contributed to the increased frequency and intensity of fires, thereby compromising the ecological resilience of the biome. Among the observed impacts, biodiversity loss, habitat degradation, and the reduction of flooded areas stand out.Thus, it is understood that the existing response mechanisms remain insufficient in the face of the magnitude of contemporary pressures, making the implementation of integrated public policies and evidence-based management strategies essential to ensure the conservation and ecological integrity of the Pantanal in the coming decades.
Panorama dos estudos sobre percepção ambiental no Sudeste Brasileiro
(Universidade Federal de São Carlos, 2025-11-24) Albuquerque, Suellen da Fonseca; Baltazar, Juliano Marcon; https://lattes.cnpq.br/8657253415860174; https://orcid.org/0009-0005-2267-6663
Environmental perception can be defined as the subjective interpretation of the environment, influenced by experiences, values, and sociocultural contexts, evolving from psychological roots to applications in environmental management and public policies. Considering this, the present study was proposed to investigate the main characteristics of research on environmental perception in the Southeast Region of Brazil through a qualitative-quantitative bibliographic review, conducted in the CAPES Periodicals database, focusing on scientific articles published between 2010 and 2025. Initially, 255 studies were identified, which, after successive screening stages by title, abstract, and full reading, resulted in 70 articles that comprise the analysis corpus. The analysis covered diverse themes, with qualitative-quantitative approaches that use questionnaires and interviews to capture attitudes and knowledge. The studied publics are concentrated in urban residents, students, and peripheral communities, while the prioritized environments are the metropolitan regions of São Paulo, Minas Gerais, and Rio de Janeiro, revealing an urban bias that underrepresents rural and coastal areas. An increase in publications was observed from 2015 onward, with a trend toward integrating environmental perception into participatory processes of municipal management and education for sustainability. The results reinforce the role of environmental perception as a subsidy to mitigate socio-environmental crises in the most urbanized region of the country, suggesting for future research comparative urban-rural analyses, mixed methods, and intercultural investigations for more inclusive policies, as well as an in-depth analysis of the results found by the analyzed studies.
Intelectualidade e poder: uma antropologia política da Revista Brasileira de Mercado de Capitais
(Universidade Federal de São Carlos, 2025-11-24) Almeida, Gabriel Henrique Lino de; Vianna, Anna Catarina Morawska; https://lattes.cnpq.br/2245801371286766; https://lattes.cnpq.br/0098027734148292; Leirner, Piero de Camargo; Luz, Manuel Ramon Souza; https://lattes.cnpq.br/3883880276055777; https://lattes.cnpq.br/5544951927644546
This dissertation examines the political and academic activities of an elite group that played a decisive role in shaping the Brazilian capital market—particularly through conducting research and proposing guidelines for the regulation and management of this key sector of the economy. The main object of analysis is the Revista Brasileira de Mercado de Capitais (Rbmec), a scholarly journal devoted to the study of the capital market and published between 1974 and 1996. Edited by the now-defunct Instituto Brasileiro de Mercado de Capitais (IBMEC), the journal became renowned for its pioneering role in fostering academic debates on the capital market in Brazil. The study begins by tracing the connections between IBMEC and a network of institutions that provided the intellectual foundation and financial and political support for the 1964 civil-military coup. It then turns to an in-depth exploration of the journal’s publications, with particular emphasis on discussions surrounding capital market regulation and the role of the State as a player within the financial industry. Adopting a political anthropology of finance approach, the dissertation situates these debates within a broader global historical framework. By doing so, it seeks to uncover the intellectual and political connections that reveal how the financial industry produces and sustains hierarchies on a global scale—thereby avoiding the trap of merely reproducing the terms and perspectives used by the financial capital itself.
Formação de docentes universitários e a interface com a Educação Especial: revisão sistemática
(Universidade Federal de São Carlos, 2025-11-24) Silva, Nathalia Carolina Carrara; Picharillo, Alessandra Daniele Messali; https://lattes.cnpq.br/6418472162902640; https://orcid.org/0000-0003-0212-8027; Orlando, Rosimeire Maria; https://lattes.cnpq.br/4254571422608459; https://orcid.org/0000-0002-0990-6146; https://lattes.cnpq.br/3698852164741561; https://orcid.org/0009-0009-4851-6595
After the 1990s, with the implementation of policies known as inclusive policies, there was an increase in the number of students with disabilities enrolling in Brazilian higher education. This demand justifies the need to examine and study the training of university professors, which, in Brazil, occurs at the postgraduate level. Thus, the general objective of this study is to investigate the pedagogical training of Brazilian university professors to work with students with disabilities, identifying its limitations and contributions to the academic trajectory of these students in higher education. Its specific objectives are: 1. To map academic publications on the pedagogical training of university professors from an inclusive perspective. 2. To identify the guidelines present in these publications for working with students with disabilities. 3. To analyze the contributions and limitations pointed out by the literature in relation to university teacher training. This is a systematic review of the literature, using the digital platforms CAPES Periodicals and SciELO and the UFSCar Institutional Repository, without a time frame, following eight basic steps of searching, storing, and selecting academic publications on the proposed theme. Four articles and one master's thesis, published between 2010 and 2021, were selected. The analyses showed that university teacher training in Brazil still focuses on scientific and technical qualifications, with little attention to pedagogical and inclusive dimensions. The absence of specific legislation to standardize training for working with special education students was identified, as well as weaknesses in initial and postgraduate training in this field. As limitations, the studies point to the lack of teacher preparation, insufficient use of accessible resources, and low participation in continuing education. As contributions, we highlight the structured offer of continuing education in many universities and the growth in the number of special education students in higher education, which has driven the debate and the need for more inclusive practices. It is concluded that it is necessary to strengthen institutional policies that guarantee continuing education, technical and pedagogical support, and practices based on equity and the appreciation of diversity, with a view to consolidating higher education that provides quality services to this population.
Shear connection and flexural behavior of steel-UHPC composite members with precast slabs under negative bending
(Universidade Federal de São Carlos, 2025-11-24) Santos, Vinicius Brother dos; Krahl, Pablo Augusto; Martins, Carlos Humberto; https://lattes.cnpq.br/1665294496138141; https://lattes.cnpq.br/8735010775914445; https://orcid.org/0000-0002-5773-2152; Araújo, Daniel de Lima; Bolandim, Emerson Alexandro; Lima, Jerfson Moura; Diógenes, Hidelbrando Jose Farkat; https://lattes.cnpq.br/8801080897723883; https://lattes.cnpq.br/9169305081866640; https://lattes.cnpq.br/4244744747948798; https://lattes.cnpq.br/6693686167483212
A combinação de aço e concreto de ultra-alto desempenho (UHPC) permite desenvolver sistemas mistos leves, duráveis e eficientes, reduzindo o consumo de materiais e prolongando sua vida útil. Entretanto, o comportamento das ligações por cisalhamento e da flexão em elementos mistos aço-UHPC com lajes pré-fabricadas ainda não é plenamente compreendido. Este estudo avalia a resposta de ligações e vigas mistas aço-UHPC sob flexão em momento negativo, com ênfase na eficiência no uso de materiais e no comportamento à fissuração. O programa experimental e numérico abrange três escalas: (i) dosagem e caracterização do UHPC e dos demais materiais empregados; (ii) avaliação do comportamento ao cisalhamento de conectores tipo pino com cabeça em aço de alta resistência (HSS) em lajes delgadas de UHPC com shear pockets, por meio de ensaios push-out; e (iii) análise da resposta à flexão de vigas mistas aço-UHPC em ensaios de três pontos. As composições de UHPC foram definidas com base em modelos de empacotamento de partículas, resultando em desempenho mecânico e trabalhabilidade equilibrados. Os ensaios push-out e as análises numéricas mostraram que o diâmetro dos pinos governou a resistência, enquanto o espaçamento e a resistência do concreto da shear pocket influenciaram significativamente o desempenho da ligação. Assim, para as configurações analisadas, espaçamentos inferiores a 2,7ds e o uso de concreto de menor resistência nas shear pockets devem ser evitados. Os resultados dos ensaios de flexão e das análises numéricas mostraram que teores de 1% e 2% de fibras controlaram de forma eficaz a abertura de fissuras dentro dos limites normativos, com efeito mínimo sobre a capacidade última. O volume de 2% aumentou a rigidez, retardou o escoamento das armaduras e promoveu múltipla fissuração, melhorando o desempenho geral em serviço. Vigas com teores moderados de fibras e taxas equilibradas de armadura apresentaram escoamento próximo ao pico de carregamento, otimizando o uso eficiente de materiais. O modelo analítico previu com precisão os momentos últimos, confirmando sua confiabilidade para uso em projeto. De modo geral, o estudo estabelece uma metodologia integrada que relaciona as propriedades dos materiais, o comportamento das ligações e o desempenho à flexão, fornecendo evidências para o projeto de elementos mistos aço-UHPC com lajes pré-fabricadas que sejam eficientes no uso de materiais e apresentem controle eficaz da fissuração.
