Monolithic refractory castables are widely used as linings in equipment subjected to high temperatures, chemically aggressive atmospheres, and severe mechanical loads, requiring high thermal stability, mechanical strength, and long-term service durability. Traditionally, calcium aluminate cement (CAC) has been employed as the binder due to its rapid development of green strength and ease of processing. However, its hydraulic nature and the transformation associated with the decomposition of its hydrates during heating may compromise the thermomechanical behavior and microstructural stability of the castables, particularly at intermediate and high temperatures. In this context, the present work investigated the thermomechanical behavior and microstructural evolution of geopolymer-bonded refractory castables synthesized from different precursors – metakaolin, calcined kaolin, and aluminum sulfate production residue –, comparing them with conventional CAC-bonded systems through advanced in situ characterization. The methodology involved formulating castables bonded with CAC and/or geopolymers, followed by physical-mechanical and microstructural characterization at different temperatures, employing in situ elastic modulus, optical dilatometry, and mechanical testing coupled with digital image correlation (DIC). The results demonstrated that binder chemistry directly influences the microstructural evolution and thermomechanical performance of the castables. Geopolymer-bonded systems progressively developed a more efficient ceramic bond through viscous sintering mechanisms, resulting in gains in mechanical strength and elastic modulus after thermal treatments. Among the formulations evaluated, the castable bonded exclusively with metakaolin showed the best overall performance, evidenced by the highest levels of densification, mechanical strength, and stiffness after firing, as well as quasi-ductile behavior at high temperatures. The integrated in situ approach proved effective in identifying phase transformations, liquid phase formation, and damage mechanisms during heating, evidencing the potential of geopolymers as alternative binders to CAC for refractories subjected to high-temperature service conditions.

El aumento de las matrículas de estudiantes con autismo en las aulas regulares ha demandado nuevas investigaciones en el campo de la Educación. Este estudio tuvo como objetivo general investigar cómo profesoras de una escuela municipal de Educación Infantil comprenden su actuación con los estudiantes con autismo. Como objetivos específicos, se buscó conocer los sentidos atribuidos por las profesoras al autismo y a la inclusión escolar; investigar cómo comprenden los desafíos y las potencialidades de su actuación; y entender cómo comprenden la relación con la familia y de qué modo la información aportada por los familiares puede contribuir a la inclusión. Fundamentada en la Teoría Histórico-Cultural, la investigación realizó entrevistas reflexivas con cinco profesoras de una escuela pública de Educación Infantil del interior del estado de São Paulo. Los resultados indicaron tres comprensiones sobre el autismo: una centrada en aspectos del estudiante y en la importancia del informe médico (mirada médico-descriptiva); otra formada por las prácticas cotidianas y las experiencias pedagógicas; y otra atravesada por incertidumbres ante la complejidad del trastorno. La educación inclusiva fue considerada importante para los niños y para la sociedad, pero se evidenciaron tensiones entre las políticas inclusivas y la realidad escolar. Los desafíos involucraron el número de niños con autismo por grupo, la falta de apoyo institucional y de formación continua, la diversidad de características de los estudiantes con TEA y dificultades en la relación familia-escuela. Como potencialidades, la Educación Infantil fue reconocida como una etapa favorable a la inclusión, por las mediaciones pedagógicas, las interacciones sociales y la dimensión lúdica. La alianza con las familias fue considerada fundamental, y la información que aportan contribuye a la comprensión de cada niño y a la actuación docente. La investigación reafirma la importancia de comprender al niño con autismo como sujeto de derechos, en su singularidad. Se concluye que es necesario invertir en la formación del profesorado, ampliar las políticas de apoyo al trabajo docente y fortalecer la relación entre escuela y familia.

This analysis investigates unconscious processes involved in the formation of social phenomena, particularly the recurring tendency of science fiction blockbusters to oppose humans and cyborgs within apocalyptic narratives. Three films released across the 1970s, 1980s, and 1990s, Westworld (1973), The Terminator (1984), and The Matrix (1999), constitute the object of analysis. Data production and collection were based on a methodological combination of sociology of cinema, psychoanalytic approaches, film criticism, and screen ethnography. Grounded in Ulrich Beck’s (2011) concept of risk society and in discussions surrounding the Anthropocene, the central hypothesis argues that the agents responsible for planetary collapse in science fiction narratives are projections of humanity itself. Such projections emerge through the denial of human responsibility for the environmental crisis and for the future of the planet. The analysis articulates historical developments in technology and their dissemination throughout the 1970s, 1980s, and 1990s in order to demonstrate how the relentless cyborg on the cinema screen may be interpreted as the repressed dimension of Anthropocene humanity, transformed into raw material for popular cinema.

This dissertation analyzes the educational project of EMEF do Campo Professor Hermínio Pagotto, a rural public school, in order to identify and understand the markers of social quality produced by its subjects (FAPESP proc.23/03785-0). In a scenario in which educational quality has been captured by managerial logic, the study asks how a school committed to the struggle for emancipatory education produces and prioritizes a quality of a different nature, one that is socially referenced. The research is grounded in the perspective of praxis and engages with investigative experiences built in partnership with schools committed to this understanding of quality. The discussion of emancipatory education draws on three references, the socialist pedagogy of the school-commune, Educação do Campo (Rural Education), and the schools of the Landless Rural Workers' Movement (MST), in dialogue with Paulo Freire and Antonio Gramsci. Methodologically, the study combines documentary, bibliographic, and empirical analysis, with interviews with education professionals, families, children, young people, and community leaders, along with collective work workshops as spaces for shared reflection. The initial organization of the corpus draws on content analysis, expanded by an enunciative perspective attentive to the context in which utterances are produced, to the materiality of texts, and to the historical, social, and institutional relations that shape the words of the participants. From these constructions of the word, the school is historicized through the threads of memory and of the lived experience of those who took part in its processes of pedagogical reformulation. This makes it possible to identify some features of its school form and the markers and conditions of quality formulated by students, families, and educators. The findings show that quality becomes intelligible in the encounter between the school's historicity and its school form, mediations that give shape to the markers and conditions of social quality. The markers comprise welcoming, work as an educational principle, an organic relationship with life, collective identity, collectivity, and human formation. They take shape in specific pedagogical practices, such as visits to the settlement plots, welcoming gatherings, collective decision-making times, and the presence of the settlement's memory in different formative moments, all organized by the school collective in ongoing dialogue with the territory. Everyday praxis, social struggle, memory, and public policies act as conditions that support the production and prioritization of these markers, which in turn guide actions capable of strengthening or reorganizing those same conditions. This relationship allows for a rethinking of the autonomy of school collectives in the construction of social quality. The study concludes that, in this school, social quality is built through reflective processes, through dialogue, and through work with the local community, in negotiation with central policies, depending on the community's own creative force more than on the definition of an ideal school model.

This dissertation investigates student dropout in stricto sensu graduate programs at the Federal University of São Carlos (UFSCar) between 2019 and 2024, understood as a systemic failure of university Public Administration. Aiming to analyse the factors associated with abandonment and to propose managerial interventions, a convergent mixed-methods design was adopted, combining statistical analysis of 29,806 student enrolment records from CAPES open microdata, documentary analysis of federal and institutional regulations, and Content Analysis of responses from 38 dropouts. The institutional dropout rate rose from 2.9% (2020) to 5.5% (2024), totalling 1,349 withdrawals, with uneven incidence across degree types — 7.40% in Professional Master's, 5.84% in Academic Master's and 2.68% in Doctoral programmes (odds ratio of 2.91 between Professional Master's and Doctoral) —, remaining below national averages, subject to methodological differences between datasets. Among respondents, the "assistance void" and the rigidity of institutional deadlines emerged as the most recurrent factors; supervisory conflicts and mental health conditions preceded withdrawals formalised under administrative labels. It is concluded that dropout entails substantial waste of public capital. In response, the Institutional Guidelines for Permanence (Technological Product) were formulated, highlighting the Integrated System for Monitoring and Welcoming in Graduate Studies (SIMAP).

Zaprionus indianus is an invasive species of African origin, widely distributed throughout Brazil and recognized for its high adaptive capacity to different environments. Intensive insecticide use in agricultural systems may act as a selective force, promoting changes in allele frequencies within natural populations. In this context, the present study aimed to compare the allelic frequencies of the Est3 locus in Z. indianus populations collected from soybean fields and urban environments, evaluating potential differences in their genetic structure. Individuals were sampled from agricultural and urban areas in the state of São Paulo, Brazil, and analyzed through polyacrylamide gel electrophoresis (PAGE) to characterize esterase polymorphisms, followed by population genetic analyses. Four alleles were identified at the Est3 locus, showing differences in frequency between the environments studied, with the Est3³ allele occurring at a higher frequency in the agricultural population. Genetic diversity indices, principal component analysis, and AMOVA revealed low overall genetic differentiation among populations. However, differences in allelic frequencies were observed and may be consistent with the influence of local selective pressures. These findings suggest that the genetic structure of Z. indianus populations is shaped by the interaction between gene flow and local environmental factors, partially supporting the hypothesis that distinct environmental contexts can influence allele distribution at the Est3 locus.

Extension curricularization is an educational policy aimed at integrating university extension into undergraduate curricula, in accordance with the Guidelines for Extension in Brazilian Higher Education. This research aimed to understand how the extension curricularization policy has been interpreted and implemented in undergraduate programs at the Federal University of São Carlos (UFSCar), based on course coordinators’ perceptions of its issues, objectives, challenges, and strategies, in light of the theoretical framework of public policy implementation. This is a qualitative study, supported by descriptive quantitative data, of an applied nature, developed through a Systematic Literature Review (SLR), document analysis, and a case study. The SLR identified challenges and strategies related to the implementation of extension curricularization in Brazilian Higher Education Institutions. The UFSCar case study involved institutional documents and an electronic questionnaire administered to undergraduate course coordinators at the São Carlos campus, with content analysis of the data. The SLR revealed a predominance of pedagogical challenges, particularly the conceptual and operational maturation of extension, the overcoming of assistentialist practices, and resistance or low engagement among faculty and students, as well as institutional challenges such as insufficient infrastructure, bureaucratic processes, and communication weaknesses. At UFSCar, significant convergence with the literature was observed, particularly regarding the conceptual maturation of extension and the need to strengthen institutional capacities. The data also revealed different understandings of the policy’s purpose, as only some respondents explicitly associated extension curricularization with student development. Among the strategies, faculty and student training and awareness-raising, active methodologies, and the creation of extension-oriented curricular components stood out, aiming to strengthen the understanding of extension as a formative dimension and promote student protagonism. The results contribute to university management and educational policies, particularly regarding pedagogical training, curricular organization, and the consolidation of extension as a constitutive dimension of academic education and the university’s social role.

This doctoral dissertation was developed within the Graduate Program in Education (PPGE) at the Federal University of São Carlos (UFSCar), under the research line Teacher Education and Other Educational Agents. The study aimed to understand the limits, challenges, and perspectives experienced by Mathematics Education researchers in structuring their doctoral dissertations developed with groups in collaborative contexts, based on the history of their histories. Grounded in Oral History as a theoretical and methodological perspective, the research identified doctoral dissertations in the field of Mathematics Education whose data were produced with groups exhibiting collaborative characteristics and conducted narrative interviews with three researchers responsible for these investigations. The narratives were produced and analyzed in the light of Oral History, seeking to understand the processes of group constitution, the challenges experienced, the strategies developed throughout the process, and the meanings retrospectively attributed to these experiences. The results revealed that the formation of groups with collaborative characteristics was a relational, dynamic, and continuously negotiated process, marked by challenges related to building trust, maintaining participant engagement, sharing leadership, reorganizing practices, and the role assumed by the researcher during the investigation. The analyses enabled the development of theoretical methodological indicators that contribute to understanding the formation of such groups and to future research conducted in collaborative contexts. It is argued that the investigation's main contribution lies in highlighting the power of Oral History to generate new understandings of past experiences, allowing researchers to revisit their trajectories, reframe investigative processes, and produce knowledge that extends beyond what was recorded in the original studies. Thus, the thesis expands the possibilities for research on groups with collaborative characteristics in Mathematics Education by offering an understanding that interlinks processes of professional development, collaboration, and knowledge production based on the narratives of the researchers themselves.

The expansion of digital platforms in São Paulo's public education, intensified after the covid-19 pandemic, has reshaped pedagogical practices, forms of school monitoring and ways of organizing teaching work, producing new demands and challenges in the daily routine of schools. This study aimed to investigate the understanding of teachers from a state public school in the municipality of Sorocaba regarding the use of digital platforms, as well as its implications for teaching and learning in the post-pandemic context. The specific objectives were: to investigate how teachers understand digital platforms, covering their pedagogical usefulness, their potential and the challenges faced in everyday school life; and to learn about their understandings of the effects of technologies on student learning and on teaching practice. The research was grounded in the historical-cultural theory of Lev Semionovitch Vigotski (1896-1934), beginning with a systematic mapping of academic works on the topic and proceeding with semi-structured interviews conducted with five teachers from the final years of Elementary School and from Secondary School. The results indicate that the potential of the platforms and the possibilities for diversifying materials and pedagogical practices are acknowledged, but the accounts reveal challenges such as standardization processes; the imposition of targets; the centralization of pedagogical decisions; the reduction of pedagogical autonomy; and the displacement of didactic planning towards tasks of monitoring, recording and tracking. The effects on learning include practices marked by haste, by the mechanical execution of activities and by superficial engagement with content. It is argued that digital platforms incorporate logics of management, control and performativity, aligned with educational policies of neoliberal orientation, which affect both the working conditions of teachers and the ways in which students learn. Understanding these processes requires considering the relations between educational policies, concrete working conditions and the forms of mediation established in everyday school life.

This thesis investigates school dropout among Black women from rural communities, understanding it as a social phenomenon produced within historical relations of inequality that condition the possibilities of access to, persistence in, and completion of schooling. Grounded in Critical Theory of Society and an intersectional perspective, the research aimed to investigate the factors that lead Black women from rural communities to drop out of basic education, considering the intersection of race, gender, economic conditions, and territory. Methodologically, the study was conducted in three complementary stages: literature reviews of national and international academic research on school dropout; descriptive statistical analysis of official data on schooling and school dropout in the Viçosa Microregion, Minas Gerais; and semi-structured interviews with eleven Black women living in rural communities across eight municipalities in the region. The literature reviews revealed a scarcity of studies on school dropout among Black women from rural communities and showed that, even internationally, race, gender, and territory tend to be investigated in a fragmented manner. The statistical analysis made it possible to assess educational inequalities but also revealed limitations in official databases regarding the simultaneous articulation of these social markers. The participants’ narratives demonstrated that the interruption of schooling did not result from individual choice or lack of interest in education, but from the combined effects of territorial barriers, economic constraints, early entry into work, racism, gender inequalities, motherhood, and exclusionary school practices. The findings showed that these factors are not experienced in isolation but intersect and reinforce one another throughout educational trajectories. It is concluded that school dropout among these women expresses historical and structural processes of exclusion that precede their departure from school and contribute to the reproduction of social inequalities, restricting access to knowledge and, consequently, the possibilities for critical education and emancipation.

This dissertation analyzes scientific output in the field of curriculum studies published in the journal Currículo Sem Fronteiras from 2001 to 2025, using a bibliometric approach combined with qualitative dimensions of analysis. The research draws on contributions from Information Science and the Sociology of Science—with particular emphasis on Pierre Bourdieu’s work on the scientific field—as well as curriculum studies, in order to situate the analyzed output within the dynamics of the production and circulation of academic knowledge. Methodologically, this is an exploratory and descriptive study that employs bibliometric analysis procedures to develop quantitative indicators, complemented by the identification of qualitative dimensions through content analysis. The quantitative results of the general characterization of the corpus show that scientific articles constitute the overwhelming majority of the published output, representing 93.15% of the total documents examined in the study.An analysis of authorship dynamics reveals a well-established trend toward collaborative intellectual production, marking the gradual decline of the traditional, individual model of academic writing. The geopolitical mapping of author contributions lays bare the limits of the effective internationalization achieved by the journal Currículo Sem Fronteiras throughout its history. Although the journal’s editorial manifesto envisioned the creation of a transnational space for critical dialogue within the Portuguese-speaking world, contributions from African Portuguese-speaking countries such as Angola and Mozambique were limited to just two articles each. The application of bibliometric indicators revealed the existence of a group of dominant actors who exercise a strong monopoly over scientific authority and dictate the journal’s theoretical trends.. An examination of the articles’ academic impact—measured using data collected from the Google Scholar platform—unveils the operation of the Matthew Effect in the distribution of scientific prestige. The temporal distribution of the most-cited publications reveals marked chronological discontinuities, which are sociologically interpreted as reflections of paradigmatic shifts and moments of maturation in the scientific literature. From the perspective of the nature of the research published, the results point to a clear dominance of basic research over applied research. The results also empirically indicate that the journal Currículo Sem Fronteiras has served as a powerful vector for professionalization, circulation, and political resistance within the curriculum field over the course of two and a half decades. The bibliometric and qualitative findings show how the accumulation of scientific capital has shaped a group of dominant actors, while the journal has ensured the dissemination of dissenting voices in the face of democratic setbacks.

Sustainability issues are increasingly valued in today's society, and many sectors of the economy are being pressured to develop more environmentally sound operations. The automotive industry, which is intensive in natural resources, is no different and faces societal pressure to evolve in favor of the environment. One of the most relevant and demanded themes concerns the application of circular economy (CE) concepts. In this sense, this work studied sustainable alternatives for the management of polyvinyl chloride (PVC) waste in the automotive sector, from the perspective of the circular economy and Life Cycle Assessment (LCA). The work was structured in two studies. The first was a systematic review (SLR) to understand the current scenario of alternatives for PVC and to confirm their efficiency via LCA. This work showed that there are promising initiatives, but they still need to mature. The second study deepened the knowledge developed in the previous study by applying LCA to a real-world case of reusing PVC waste from the automotive painting process, used in the manufacture of PVC automotive mats. The results obtained were promising, highlighting the reduction of potential environmental impacts in practically all evaluated categories and reinforcing the environmental benefit associated with the circularity of PVC. It was identified that the main hotspot in the material's life cycle—evaluated from a cradle-to-grave approach in its application as a raw material for automotive mats—is concentrated in the virgin PVC production stage, which confirms the advantages of adopting practices aligned with the circular economy. In a comprehensive way, this work directly contributes to the advancement of PVC circularity in the automotive sector and can support the development of industrial initiatives and public policies aimed at promoting the circular economy.

This study aims to analyze the periods between 2011 and 2025 in which the development of curriculum policies for Physical Education in Sorocaba moved closer to or further away from a liberating conception of curriculum policy, using the São Paulo Curriculum Reorientation Movement as a reference. It is grounded in the understanding that the curriculum is not merely a neutral document for organizing content, but rather an expression of societal projects, political disputes, power relations, and educational intentions. To this end, the study contextualizes the history of Brazilian curriculum policies, the specificities of Physical Education within this trajectory, and the Physical Education Renewal Movement as an important milestone in the construction of critical and counter-hegemonic possibilities for the field. The research is theoretically grounded in Historical-Dialectical Materialism and Paulo Freire’s Liberating Education, understanding the São Paulo Curriculum Reorientation Movement as a concrete manifestation of a liberating curriculum policy. The methodological approach is qualitative and comprises bibliographic research and documentary analysis, with the data examined through Discursive Textual Analysis. The documentary corpus, consisting of Sorocaba’s curriculum documents, was analyzed according to four categories: autonomy, educators’ continuing professional development, collective participation, and the valuing of the relationship between theory and practice. The analysis led to the emergence of the interpretive categories of political-curricular invasion and political-curricular synthesis, which were used to understand the development of curriculum policies in Sorocaba. The findings indicate that this process did not occur linearly, but was characterized by convergences, divergences, contradictions, and ruptures in relation to the principles of a liberating curriculum policy. Among the documents analyzed, the second version of the Reference Framework showed the closest alignment with political-curricular synthesis, whereas the Curriculum Matrix, the SESI Curriculum, and, to some extent, the São Paulo State Curriculum and the Planning Guidelines Handbook revealed tendencies toward political-curricular invasion. It is argued that overcoming this scenario requires the establishment of a curriculum reorientation movement in Sorocaba, developed through a democratic, dialogical, collective, and ongoing process, with a view to fostering a critical and humanizing education committed to transforming concrete reality.

This research aims to analyze the knowledge and challenges regarding Education for Ethnic-Racial Relations and curriculum decolonization made explicit by school principals working in schools in a city in the interior of São Paulo state, starting from the research question: "What knowledge and challenges regarding Education for Ethnic-Racial Relations and curriculum decolonization are made explicit by school principals?" The study is grounded in the concepts of coloniality of power, of knowledge, and of being, articulated with the perspective of decoloniality as a way of confronting the Eurocentric structures present in Brazilian education, drawing on the theoretical contributions of Quijano (2005, 2007), Mignolo (2017), Walsh (2018), Gomes (2012, 2013, 2018, 2019), Kilomba (2019), Bento (2022), and other authors in the anti-racist and decolonial field. This is a qualitative study, carried out by means of an electronic questionnaire applied to twenty-two school principals from the state education network in a city in the interior of São Paulo, with approval from the Research Ethics Committee and from the School for Training and Improvement of Education Professionals (EFAPE). Data were analyzed through Content Analysis. The results show the presence of different levels of racial literacy among participants — Critical, Normative, and Reactive — indicating that principals with a broader understanding of ethnic-racial relations tend to develop formative processes more closely articulated with the curriculum and with the Political-Pedagogical Project, and that insufficient initial training, the discontinuity of formative policies, and the managerial model adopted by the São Paulo state network constitute significant obstacles to the implementation of ERER and curriculum decolonization. As an educational product, the Trilha Formativa Reexistir em ação: porque nós somos — trilha formativa para uma educação antirracista e decolonial was developed, structured around five thematic axes and grounded in Ubuntu philosophy. It is concluded that the school principal occupies a strategic position in promoting anti-racist and decolonial practices, acting as an organizer of collective formative processes able to strengthen the construction of a school culture committed to racial equity and social justice.

This study analyzes the alternative developed by the municipal government of Sorocaba to address the housing needs of families specifically the Programa Lotes Sociais (PLS), implemented by the Department of Housing and Land Regularization (SEHAB). The PLS entails the transfer of ownership—via a conditional donation—of lots up to 125 m² to beneficiaries of the Auxílio Moradia program (municipal rent subsidy) or to families living in Areas of Special Social Interest (AEIS) where regularization was previously blocked. This process involves reclassifying public institutional land for residential use, subject to a technical feasibility study and legislative authorization. The study involved interviews with well-informed public officials responsible for designing, managing, and implementing the Social Lots proposal. Research findings indicate that the PLS expands housing options and helps reduce vulnerability. However, access to land does not immediately guarantee housing security, as the program's effectiveness depends on the responsibility for constructing the home a task requiring financial capacity, a reasonable level of technical know-how, and a stable income.

Inspired by the idea that historically silenced subjects need to narrate their own stories, this dissertation understands narrative as a political, formative, and epistemological act in response to school and media traditions that have historically erased Black voices and experiences. The research was guided by the following question: how can audiovisual production, grounded in the principles of educommunication and guided by an anti-racist and decolonial perspective, express the youth protagonism of high school students? The general objective was to analyze audiovisual production as an expression of youth protagonism among high school students, based on the Nossas Narrativas project, developed in a public state school in the interior of São Paulo, Brazil. The project involved the production of podcast episodes and audiovisual materials addressing memory, identity, representation, epistemicide, and youth protagonism. Methodologically, this is a qualitative study, configured as a single embedded case study and articulated with a quantitative-descriptive diagnostic stage. The investigative process involved the analysis of a diagnostic questionnaire applied by the Student Council to 282 students, the constitution of the participant group, an educommunication and racial literacy workshop, production meetings, podcast recordings, field diary, focus groups, individual interviews, document analysis, and systematization of the Educational Product. The final production group consisted of six students. Data analysis was conducted based on Content Analysis, in dialogue with the Baobab of Concepts, a theoretical-analytical matrix constructed to articulate coloniality of knowledge, epistemicide, critical racial literacy, educommunication, audiovisual production, youth protagonism, and empowerment. The analytical triangulation, guided by five theoretical propositions and by the methodological procedures of the case study, resulted in differentiated verdicts: three propositions were supported with qualification, one was supported with methodological reservation, and one was partially supported. The data indicate that audiovisual production, when guided by anti-racist pedagogical intentionality, enabled participants to name erasures, formulate questions, interview Black reference figures, control narrative devices, and publicly circulate their productions. Three central analytical axes were identified: narrative sovereignty, Black intellectuality on scene, and supportive horizontality. The individual interviews indicated subjective and formative shifts in the participant subgroup, especially in the way they recognized Black references, interpreted the school, and understood their own position in the production of narratives. However, the study design does not allow for longitudinal monitoring of the permanence of these shifts nor for statistical generalizations to non-comparable contexts. As a practical contribution, the Educational Product Nossas Narrativas was developed, consisting of a digital repository and an educommunication and podcasting guide aimed at Basic Education teachers. The study argues that anti-racist education is not consolidated through isolated actions, since it requires continuity, collective elaboration and openness to silences and to different rhythms of participation.

Fluorinated compounds are highly relevant in contemporary chemistry due to the unique properties imparted by fluorine and are widely employed in the development of molecules of pharmaceutical and agrochemical interest. In this context, the introduction of fluoroalkyl groups represents an important strategy for modulating the properties of organic molecules. Although numerous methodologies have been developed, many still require harsh reaction conditions, transition metals, or reagents that are difficult to handle. In light of these challenges, visible-light photocatalysis has emerged as an efficient and sustainable approach for the controlled generation of radical species under mild conditions. This thesis therefore focuses on the development of metal-free photocatalytic methodologies for the incorporation of fluoroalkyl groups into organic substrates, with the aim of functionalizing molecules with potential bioactivity. In this context, Chapter 1 describes the development of a protocol for the difluoroacetylation and difluoroacetamidation of peptides containing the amino acid tryptophan. The methodology showed good compatibility with di- to heptapeptide sequences, enabling the synthesis of 21 products in yields of up to 73%. Mechanistic studies were also conducted, providing insights into the nature of the species involved and the proposed mechanism of these transformations. Chapter 2 focuses on the difluoroacetylation of vinyl-C-glycosides, a class of sugar-derived olefins, for the synthesis of glycoamino acids and difluoroalkylated neoglycopeptides. The approach enabled the synthesis of 24 products in yields of up to 81%, demonstrating compatibility even with unprotected sugar derivatives. Mechanistic studies were also conducted to investigate the steps involved in the process. Finally, Chapter 3 describes the development of a domino synthetic strategy for the preparation of a new class of perfluoroalkyl- and difluoroalkylsubstituted 2-pyrazolin-5-ones. The methodology exhibited broad functional group tolerance, enabling the investigation of an extensive substrate scope comprising 44 examples, with isolated yields ranging from 17 to 90%, and was successfully translated to a continuous-flow photochemical system. Complementary mechanistic studies provided further insights into the transformation and supported the proposed reaction mechanism. Overall, the strategies developed in this thesis expand the possibilities for the synthesis of fluorinated compounds through efficient, mild, and sustainable photocatalytic methodologies.

In the Portuguese language, more specifically in Brazilian Portuguese, items such as só (“only”), somente (“only”), exceto (“except”), among others of this nature, can be classified in formal semantics as “exclusives.” There are no solid analyses in the formal semantics and pragmatics literature that examine these items in Brazilian Portuguese from this perspective. In light of this, the present study investigates exclusive items in Brazilian Portuguese through two theories of exclusives, which we will refer to as Coppock and Beaver’s (2013) “Maximum and Minimum Theory” and Wiegand’s (2018) “Morphosemantic Theory,” with the aim of proposing a minimal typology for these items and structures in Brazilian Portuguese. Both theories focus on exclusives in English, particularly the particles just and only: the former argues that exclusives contain a presuppositional component (minimum) and a quantificational component (maximum), while the latter argues that exclusives operate directly on sets of alternatives ranked by the speaker.We propose that Portuguese exclusives also fit within the theoretical frameworks presented and can initially be classified into two distinct groups: Focus Exclusives and Negation Exclusives. The former aim to delimit and/or exclude elements from a larger set to which they belong (as in só and apenas in sentences such as “Eu só/apenas falo português” — “I only speak Portuguese”); the latter focus on the contrast between two sets, necessarily involving the negation of one set in relation to the other (as in exceto in sentences such as “Todos vieram me ver, exceto João” — “Everyone came to see me, except João”).There are also cases in which certain exclusives behave differently from the proposals by Coppock and Beaver (2013) and Wiegand (2018), referred to by Beltrama (2021) as Emphatic Exclusives (EE). These operate by delimiting and/or negating alternatives within their scope (in English, the item just, and in Brazilian Portuguese, simplesmente), as in the sentence: “Este filme é simplesmente maravilhoso” — “This movie is simply wonderful.” In this case, for the speaker, there would be no other adjectives that could be inserted as alternatives to maravilhoso (“wonderful”).

The conventional extensive livestock farming model generates significant environmental impacts, reinforcing the need for sustainable alternatives such as Silvopastoral Systems (SPS). This study evaluated the silvicultural response, biomass accumulation, and morphological composition of mulberry (Morus nigra L.), gliricidia (Gliricidia sepium (Jacq.) Walp), and tithonia (Tithonia diversifolia (Hemsl.) A. Gray) subjected to North/South (N/S) and East/West (E/W) planting orientations. The experiment was conducted at UFSCar, Araras-SP, using a completely randomized design with six replicates per treatment. Height, stem diameter, and canopy diameter were evaluated at 10, 20, and 30 days of growth, in addition to green mass production (GMP), dry mass (DM), dry matter content (DM%), and the leaf-to-stem ratio at 30 days of regrowth. Evaluations were performed every 10 days over a 12-month period, from March 2024 to February 2025. Data were analyzed using the SAS PROC MIXED procedure. There was no triple interaction (cycle/time/planting orientation) for the morphometric variables (P ≥ 0.058). In general, the E-W orientation favored initial vegetative vigor, increasing height and canopy diameter for mulberry, stem diameter for gliricidia, and both stem and canopy diameters for tithonia. For mulberry, the E-W arrangement increased fresh biomass yield (333 vs. 184 kg ha¹ cycle¹) and dry biomass yield (86.7 vs. 51.9 kg ha¹ cycle¹), while reducing dry matter content. For gliricidia and tithonia, the orientation did not alter biomass production or dry matter content. Morphological partitioning was also unaffected, maintaining mean leaf proportions of 706, 811, and 688 g kg¹ for mulberry, gliricidia, and tithonia, respectively. Peak biomass production occurred between October and January/February, coinciding with the period of greatest water and thermal availability. It is concluded that the E-W orientation favors initial development and can increase biomass productivity, particularly for mulberry. However, forage accumulation is strongly influenced by climatic seasonality, indicating that cutting or grazing management should be flexible and guided by morphological indicators, such as canopy height

The rapid process of population aging in Brazil has increased the necessity of strengthening the care networks directed to the elderly population. In this context, the present study objectified a comparative analysis of the territorial distribution of the services of Primary Health Care (APS), of Basic Social Protection (PSB) and of Intersectoral Services destined to the elderly person in the five Brazilian regions, considering the years 2022 and 2024. The dissertation was elaborated through a qualitative bibliographic review about the challenges of APS in the care to the elderly person and of a descriptive quantitative study based on data originating from the DGeroBrasil project. Furthermore, complementary information from the National Registry of Health Establishments (CNES), SUAS Census and other official public databases were utilized. The bibliographic review identified challenges related to the essential attributes of APS, highlighting the high turnover of professionals, weaknesses in the articulation of the service network and difficulties of access to the assistance. As demonstrated in the analysis of the services, in the year 2022, 31,514 services of APS, 15,994 of PSB and 4,281 Intersectoral Services were identified. The proportional analysis demonstrated the existence of regional inequalities, with greater population coverage of services in the South region and greater proportions of services per municipality in the North region. Between 2022 and 2024, an increase of 5,749 units was observed in APS, totaling 37,263 services, while PSB registered an increase of 491 units, reaching 16,485 services. In counterpoint, the reduction of 875 Health Posts and of 203 teams of the Family Health Strategy was verified. In the Intersectoral Services, an increase of the registries of Municipal Councils of the Elderly Person was observed, from 821 to 4,027. However, the unavailability of standardized data for part of the intersectoral devices in 2024 limited the temporal comparison and the complete analysis of this component. It is concluded that, despite the amplification of the offer of services directed to the elderly population between 2022 and 2024, important territorial inequalities persist in the distribution of the resources of health, social assistance and intersectoral protection. The results of the study reinforce the importance of planning, of monitoring and of the strengthening of the care networks, as well as of the qualification of information systems, aiming to promote greater equity in the care to the Brazilian elderly population.
