Despite the progress women have made in recent decades in terms of participation in the labor market and other spheres of public life, recent studies have revealed growing wage disparities affecting women. Considering the importance of the Information Technology (IT) sector to the Brazilian and global economy, it is essential to discuss wage differences and their impacts, especially on women's professional and personal lives. Therefore, the objective of this study is to analyze the wage disparities faced by women working in the Information Technology field in the city of Sorocaba, identifying and investigating the causes of these differences. The research sought to understand how socioeconomic, cultural, and organizational factors contribute to gender wage inequality in this sector. The study adopted a quantitative-qualitative approach. Initially, an analysis of data from the Annual Social Information Report (RAIS), from 2018 to 2022, for workers in the city of Sorocaba-SP, was carried out, followed by the application of the Oaxaca-Blinder decomposition method using the Python data science programming language. Subsequently, semi-structured interviews were conducted with IT professionals of both genders to investigate their perceptions and experiences of gender discrimination in the workplace. Finally, the research identified wage differences between men and women in the IT sector in Sorocaba, showing a significant increase in disparities: from 9.51% in 2018 to 19.45% in 2022. On average, 95% of this difference was attributed to discrimination. The interviews complemented these findings by offering a deeper understanding of working conditions and the factors that perpetuate wage inequality, revealing a scenario of discrimination, but also highlighting the importance of equity policies and initiatives that promote fairer environments.

This thesis investigates how teaching knowledge mediates the construction of senses and meanings attributed by Physical Education teachers to the National Common Curricular Base (BNCC). The investigation stems from the gap identified in the absence of studies analyzing the direct perspective of the teacher, assuming them as a reflective agent rather than a mere executor of curricular prescriptions. The study is characterized as qualitative, descriptive, and exploratory research organized into two stages: the descriptive phase, with the application of a questionnaire to 260 Physical Education teachers in Basic Education across all Brazilian states, and the exploratory phase, consisting of three focus groups with 15 teachers. The narratives were analyzed using Bardin's Content Analysis under the theoretical lens of Vygotsky's concepts of Sense and Meaning, Tardif's Epistemology of Practice, and Schön's Reflection-in-action and Reflection-on-action. The findings reveal that the implementation of the BNCC is a heterogeneous phenomenon mediated by a hierarchy of knowledge. Knowledge of Professional Training and Disciplinary Knowledge act as a foundation for a critical and ideological reading of the document, while Experiential Knowledge gives materiality to curricular prescriptions in the face of concrete teaching work conditions. Finally, Curricular Knowledge allows teachers to "play by the rules," preserving their institutional autonomy. The study demonstrates that teachers attribute multiple senses to the BNCC, including opposition, bureaucracy, non-adherence, legitimation, validation, systematization, and curriculum, depending on the circumstances. It concludes that the BNCC, a technical and cold document in its constitution, takes shape through the actions of teachers, whose voices reveal a pragmatic positioning towards it, indicating that any curricular policy only materializes within the subjectivity and conscious decision-making of those who operate on the school floor.

Humanity has long dreamed of robots performing a wide variety of functions; nowadays, this is closer to reality than one might imagine. Given the explosion and spread of robot use, and the advent of drones, building and designing these machines has become increasingly challenging. To remedy this situation, various technologies have emerged, such as powerful and compact middleware and hardware, as well as development and testing techniques that have accelerated and reduced the cost of drone design. However, testing these aircraft quickly and safely during their development has become a challenge. To mitigate this problem, this work seeks to conceptualize an environment capable of assisting drone development, using software and hardware-in-the-loop techniques, aligned with the use of embedded systems, simulations, and a physical model of one of the drone’s axes. Preliminary results show that embedded Linux is capable of controlling the simulation stably and with tolerable latency values.

Autism Spectrum Disorder (ASD) is characterized by impairments in communication and social interaction, and restricted and repetitive patterns of behavior. Characteristic signs of ASD are present from the child's first months, and their recognition constitutes a protective factor against possible worsening of the characteristics, as well as the possibility of an improvement in development and an increase in adaptive, verbal, and social behaviors. Teachers point to difficulty in recognizing these signs at school due to a lack of knowledge on the subject. Therefore, the objective of this work was to create, evaluate and implement an remote expository in-person training action on the identification of early signs and characteristics of ASD in Early Childhood Education teachers. The research used a single-subject quasi-experimental design with pre- and post-tests and follow-up. The procedures used were an initial assessment (pre-test), training, followed by a final assessment (post-test), at the end of the three stages, and after two months was applied the follow-up. The participants were three teachers. The results indicated that the participants began to recognize the early signs and definitions of ASD. This result corroborates previous findings in the literature that also indicated that training, even of short duration, can produce advances in teaching knowledge about ASD.

The FPA, the most influential parliamentary group in the Brazilian National Congress, has been acting decisively to deregulate the use of pesticides in the country. Given this scenario, this research investigates a gap in the debate about the role of the Brazilian legislature in promoting Necropolitics, a concept derived from Foucault's studies on Biopower and further developed by Achille Mbembe. Necropolitics refers to the management of death, determining who has the right to live and who is excluded from society, becoming the target of neglect or marginalization. Using this theoretical approach, we analyze the FPA's actions in the legislative processes that resulted in recent changes in pesticide regulation. To this end, we examine federal legislative proposals on the subject between 2019 and 2024, considering the FPA's influence in occupying strategic positions on thematic committees and in guiding the parliamentary group, imposing categories of analysis to characterize necropolitical agents. The results point to the FPA's dominant position and its success in defending the interests of agribusiness, even when this implies negative impacts on the environment and the State's mission regarding the risks to the health and well-being of populations exposed to the use of pesticides, including consumers, farmers, and rural workers.

This doctoral research, set in the North of Minas Gerais and inspired by João Guimarães Rosa's concepts of “Sertão” (Backlands) and “Travessia” (Crossing), investigates the initial education of Mathematics teachers in the face of challenges in a context mediated by digital artifacts. The study problematizes the instrumental view and technological determinism, manifested under the logic of “technological salvationism.” In opposition to this dominant view, the defended thesis is that Teacher Authorship of digital games acts as a sociotechnical formative device, capable of stressing the naive consciousness about technology and breaking the illusory belief in its salvationist power. This authorship transcends the mere technical production of the artifact, configuring itself as a recursive and inseparable cycle of creating to apply, and applying to (re)signify the creation. Accordingly, the guiding research problem was defined as: What are the contributions and limits of a formative experience based on Teacher Authorship for the professional constitution of pre-service Mathematics teachers, grounded in their perceptions of the design, development, and mediation of digital games in teaching? The general objective was established to investigate the contributions and limits of a formative experience based on Teacher Authorship for the education of Mathematics teachers, analyzing the perceptions and reflections constructed by pre-service teachers based on the experience of conception, programming, and didactic use of digital games. The specific objectives unfold as follows: i) to understand the implications of Teacher Authorship in the constitution of the participants' perceptions regarding the tensions, algorithmic barriers, and reflections experienced during the digital game development process; and ii) to analyze the pre-service teachers' reflections and perceptions regarding the potentialities and limits of pedagogical mediation, evidenced through the experience of using these authorial artifacts in real teaching contexts in Basic Education. Grounded in Brigitte Albero's Sociotechnical Approach, Álvaro Vieira Pinto's philosophy of technology, and the assumptions of experience (Jorge Larrosa) and reflection (John Dewey), the research adopted a qualitative approach. Data were produced at the Federal Institute of Northern Minas Gerais (IFNMG – Januária Campus), where four pre-service teachers experienced “Teacher Authorship,” which consisted of designing, coding, and mediating the use of their own games in public schools. Data interpretation was carried out through Discursive Textual Analysis (DTA). The results attest to the validity of the thesis by showing that immersion in this authorial cycle provoked real fissures in the participants' technical consciousness. The confrontation with the realities of the "school floor" and with the subversions of Basic Education students shattered the myth of plug and play, forcing the pre-service teachers to face a zone of pedagogical risk. It is concluded that Teacher Authorship transcends software appropriation, configuring itself as a tensional process of alterity, empathy, and political literacy. The research also denounces applicationist curricular models and structural school precarization, arguing that, in the face of technology, a politically awakened teacher conscious of their intentionality is the most revolutionary “technology” in the classroom.

Freshwater ecosystems are increasingly subjected to multiple pressures, including climate change, pollution, and alterations to the hydrological cycle. This context creates a multi-stressor environment for organisms inhabiting aquatic systems, such as macrophytes, plants that occupy wetlands or fully aquatic habitats. Plant communities are directly influenced by temperature, which modulates their metabolic rates and growth parameters, and may interact synergistically with other stressors, such as chemical pollutants. Bisphenol A (BPA) is a synthetic organic compound widely used in plastic production and is an emerging contaminant that interacts with aquatic organisms, including macrophytes. The objective of this study was to evaluate the effects of bisphenol A and temperature, within a climate change context, on two macrophyte species (R. natans and S. auriculata). The following hypotheses were tested: (i) BPA would exert negative effects on plant growth and development; (ii) a 2 °C temperature increase would synergistically interact with the contaminant, potentiating its toxic effects; and (iii) R. natans and S. auriculata would exhibit similar growth responses when exposed to identical conditions. Specimens of both species were individually exposed to bisphenol A concentrations of 0 mg/L (control), 2.5 mg/L, and 10 mg/L (50 individuals per concentration) and maintained at two temperature regimes, 21.5 °C and 23.5 °C, over a 6-week period. Leaf area was measured weekly, and the remaining bisphenol A concentration was determined. At the end of the experimental period, dry and fresh biomass of the macrophytes were determined gravimetrically. S. auriculata proved more sensitive to the contaminant, particularly at the highest concentration (10 mg/L), exhibiting visible signs of deterioration, including chlorosis and senescence. The higher temperature (23.5 °C) promoted growth and enhanced resistance/resilience to the contaminant in this species. In contrast, R. natans showed deleterious responses to higher temperatures, with negative effects on growth parameters and an apparent reduction in contaminant absorption/adsorption. Thus, under a multi-stressor scenario, S. auriculata may benefit from increased temperature but may be adversely affected by bisphenol A. Conversely, R. natans demonstrated phytoaccumulation potential for bisphenol A but was adversely affected by elevated temperatures.

Social Interaction and Cooperative Centers (CECCOs) are strategic components of Brazil's mental health policy and the Psychosocial Care Network (RAPS), guided by principles of care within the community, social participation, inclusion, and the co-creation of the "common." These facilities feature interprofessional teams—notably including occupational therapists, whose practice has historically contributed to creating spaces for social interaction, participation, and cultural production, as well as strengthening community ties. Although social interaction holds a central place in the organization of these services and the practices of occupational therapists, the concept remains multifaceted and continues to evolve within the field of occupational therapy. Against this backdrop, the general objective of this research was to identify how occupational therapists at CECCOs in the city of São Paulo conceive and practice social interaction. A specific objective was to analyze the relationship between the conceptions of social interaction adopted by these professionals and the practices implemented in the services. This study employed a qualitative approach with an exploratory and descriptive design, conducted at eight CECCOs in São Paulo. Eight occupational therapists working at different CECCOs participated in the study; all had at least one year of experience in these services and were directly involved in daily social interaction practices. Data collection involved two instruments: an Occupational Therapist and CECCO Characterization Form and a semi-structured interview guide. Form data were analyzed descriptively, while interview data underwent thematic analysis. Four categories emerged from this analysis: Category 1 – Historical, organizational, and symbolic dimensions of CECCOs; Category 2 – Social interaction: conceptions, understandings, and practices; Category 3 – Interplay between social interaction and occupational therapy; Category 4 – Sociopolitical aspects of social interaction and their repercussions within CECCOs. The results show that social interaction emerges as a structuring axis of the work at CECCOs, revealing that interacting involves sharing experiences, building together, and recognizing the other in their uniqueness. They further highlight that this experience requires creating conditions where different ways of being and existing in the world are welcomed. This ethical dimension serves as a prerequisite for building more inclusive and solidary societies. Social interaction entails the continuous practice of recognizing the legitimacy of the other and sustaining relationships that transcend prejudices, stigmas, and normative expectations; this materializes in concrete practices regarding the organization of daily life, the facilitation of groups, the mediation of encounters, and the creation of spaces for participation and belonging. Thus, a close relationship is observed between how occupational therapists understand social interaction and the practices they implement; their conception of it as a relational, ethical, and collective process translates into interventions that prioritize encounters, listening, and openness to difference. Social interaction, as practiced in CECCOs, is considered a structuring axis of Occupational Therapy practice and a fundamental dimension of psychosocial care, contributing to the fostering of autonomy, social participation, and the right to the city, while highlighting the specific role of Occupational Therapy in sustaining practices committed to care within a context of freedom.

The present study investigates, based on both formal and functional factors, irony as a marker of viewpoint in the construction [só que XAdv] within the framework of Cognitive Linguistics, more specifically according to the Construction Grammar paradigm (Goldberg, 1995, 2006). By applying the properties of schematicity, productivity, and compositionality, proposed by Traugott and Trousdale (2013), this work characterizes [só que XAdv] with respect to its form and function. Moreover, drawing on the insights of Lehmann and Bergs (2021), it asserts its status as a construction irony, whose ironic interpretation, once embedded in the collective imagination, is immediately recognized. Furthermore, owing to the inherent irony in [só que XAdv], this construction emerges as a prototypical case of perspectivization, based on the Theory of Viewpoint (Tobin; Israel, 2012). To that end, adopting a methodology that, with synchronic and qualitative data, accounts for that actual use of contemporary Brazilian Portuguese, we make use of O Corpus do Português (Davies; Ferreira, 2016), specifically the NOW and Web/Dialects subcorpora, and conduct two search rounds. In this context, using the tag só que ADV and the Brazil filter, the findings indicate that the construction is (i) more schematic, evidenced not only by the presence of constructions such "só que não", "só que nunca", and "só que sim", but by "só que jamais", along with variations incorporating some type of intensifier/reinforce or modalizer; (ii) more productive, since, beyond the diversity of adverbs that may fill the slot X, combinations such as "só que infelizmente não", with an evaluative modalizer, reveal the schema’s capacity to continue licensing new instances; and (iii) less compositional, as the mere sum of the parts constituting the constructions instantiated by the relevant schema is insufficient to establish their full meaning. Moreover, [só que XAdv] should be analyzed as a constructional irony, insofar as it involves a schematic formal structure, a conventionalized association with an ironic effect, and an interpretive shift away from literal meaning. From a discursive standpoint, the construction also exhibits a scalar pattern of negation, ranging from more mitigated to more categorical forms, in the following gradation: só que talvez não < só que não = só que também não < só que não mesmo < só que nunca = só que jamais. Finally, the analysis highlights the perspectival shift brought about by the irony encoded in the schema, which involves a movement from a lower semantic level to a higher pragmatic one. However, such perspectivization, unlike what is elucidated by Tobin and Israel (2012), occurs automatically, requiring no extra inferential effort on the part of the interlocutor, since it constitutes a case of constructional irony, as proposed by Lehmann and Bergs (2021). Thus, this study aims to contribute to the advancement of linguistic studies in written Brazilian Portuguese variation, insofar as, by investigating and documenting a construction that has become established across different registers and contexts, it seeks to reveal irony as a sophisticated component of everyday communication. This is because it exceeds predictable meaning by dissimulating literary, rhetorical, and social effects and, therefore, functions as an essential tool for shaping and expressing viewpoints.

In this work, we present applications of Graph Theory to the study of polynomial identities for the matrix algebra $M_n(K)$. Initially, we establish the fundamental concepts of PI-theory and Graph Theory, emphasizing the definition of Eulerian graphs. We analyze the Amitsur-Levitzki Theorem in detail through the proof proposed by Richard Swan [11], which utilizes the counting of Eulerian paths in directed graphs to simplify the algebraic problem. Subsequently, based on the work of Szigeti, Tuza, and Révész [13], we explore how specific graph constructions allow for the formalization of the conditions for the existence of these identities. Finally, we highlight that understanding this technique not only simplifies classical results but also establishes itself as a powerful tool for discovering new identities in PI-algebras.

This study investigates the development and characterization of composite membranes based on cellulose nanofibrils (CNF) and molybdenum trioxide (MoO3) for the removal of the cationic dye methylene blue (MB) from aqueous effluents. The experimental approach systematically varied the concentrations of CNF (0.5–2.0%) and MoO3 (1–10%) to elucidate the relationship between the support matrix microstructure and the adsorptive performance of the active phase. Characterization was performed through structural analyses (SEM, XRD, FTIR, and porosity), kinetic studies, and adsorption isotherms. The results indicate that the incorporation of MoO3 promotes modifications in surface interactions, as reflected by the better fit to the pseudo-second-order kinetic model. The adsorptive process is predominantly governed by electrostatic interactions between the negatively charged membrane surface pHPZC (3,5) and the methylene blue in aqueous solution for both membranes with and without the oxide. The main finding of the study was the identification of an inverse relationship between CNF concentration and adsorption capacity. This behavior was attributed to a reduction in membrane porosity resulting from structural compaction (hornification), which limits mass transport and reduces accessibility to the active MoO3 sites. The N0.5Mo5 formulation (0.5% CNF and 5% MoO3) exhibited the best performance, with a maximum adsorption capacity of approximately 453,4 mg/g, resulting from a balance between high porosity and adequate dispersion of the active phase. The results demonstrate that the microstructural porosity of the support matrix is the dominant factor in the composite's performance, outweighing the influence of the amount of active material and establishing an important design principle for the development of high-performance adsorbent materials.

This work investigates a NiCoP catalyst obtained by electrodeposition for alkaline water electrolysis. Since the electrodeposition conditions directly influence the morphology, composition, and electrocatalytic activity of the film, a central composite design was employed to optimize the catalyst electrodeposition conditions. The studied variables were the concentrations of [NiSO4], [CoSO4], and [NaH2PO2], as well as the applied current density (jd), while the responses of the experimental design were the overpotentials at 10 and 100 mA cm⁻2 (η10 and η100, respectively) for the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). The obtained films exhibited limited activity toward the OER, with a maximum overpotential reduction lower than 50 mV compared to the stainless steel substrate. In contrast, promising results were observed for the HER, with a coefficient of determination (R2) of 80.2 % for η10, where the NiSO4 concentration and current density were identified as significant effects at a 95 % confidence level. Although [CoSO4] and [NaH2PO2] were not statistically significant, the complete removal of these salts severely compromised the catalytic performance. However, the desirability study indicated that their concentrations can be reduced by up to 50 % and 80 %, respectively, without significant loss in HER activity or catalyst composition. In the second stage, the optimized electrodeposition condition for the NiCoP catalyst was evaluated in an anion exchange membrane water electrolyzer (AEMWE), using Ni3Fe-LDH as the anode in 1.0 mol L⁻1 KOH solution at Forschungszentrum Jülich, Germany. The polarization curves recorded for this system before and after 240h of operation at 1.0 A cm⁻2 showed similar profiles, reaching 1.0 A cm⁻2 at 2.00 V. Overall, this work demonstrates the potential of electrodeposited NiCoP, a simple and low-cost synthesis method, as a catalyst with competitive electrochemical performance for the HER in AEMWE systems.

The olive tree (Olea europaea L.) was introduced into Brazil more than two centuries ago and faces phytosanitary challenges such as Fusarium wilt, caused by fungi of the genus Fusarium, which leads to vascular browning, root necrosis, and dieback of the aerial parts. Conventional management includes the elimination of infected plants and the use of healthy seedlings. However, these strategies present limitations. As an alternative, biological control using fungi of the genus Trichoderma has gained attention due to its antagonistic activity against phytopathogens. In addition, essential oils have attracted interest because of their antifungal properties and low toxicity. This study evaluated the effects of essential oils on three isolates of the genera Trichoderma (CMO 16, CMO 48, and T221A) and two isolates of the genera Fusarium (FUS 1 and FUS 2), both individually and in combination, to investigate their potential as a strategy for the control of Fusarium wilt in olive trees. Seven essential oils were tested: lemongrass (Cymbopogon citratus), clove leaf (Syzygium aromaticum), spearmint (Mentha spicata), peppermint (Mentha piperita), oregano (Origanum vulgare), palmarosa (Cymbopogon martinii), and Piper aduncum L. (Piper), through individual growth and fungal antagonism assays. The data were subjected to analysis of variance (ANOVA) and presented as dot plots and heatmaps. The three Trichoderma isolates showed high tolerance to most essential oils, exhibiting maximum growth in the presence of lemongrass, spearmint, and peppermint oils. Fusarium growth was significantly inhibited, particularly by clove leaf and oregano essential oils at higher concentrations. The combination of Trichoderma and essential oils enhanced the suppression of Fusarium. The best results were obtained at the lowest concentrations of lemongrass, spearmint, and peppermint essential oils. These findings indicate that the combined use of Trichoderma and essential oils represents a promising and sustainable strategy for the control of Fusarium wilt in olive cultivation.

This thesis investigates the temporal coherence properties and collective effects of light scattered by disordered ensembles of cold atoms. Using cold atomic clouds as a highly controllable experimental platform, we combine measurements of first- and secondorder optical correlation functions with theoretical modeling and numerical simulations to characterize different scattering regimes. We first examine the Siegert relation, establish the conditions for its validity, and experimentally verify its applicability in our system as a simple link between first- and second-order correlation functions. We then identify a transition between two distinct light-scattering regimes, characterized by different mechanisms responsible for coherence loss: a classical, atomic motion-induced mechanism at low saturation and a quantum fluctuations-driven mechanism associated with spontaneous emission under strong saturation. Next, we investigate the role of the atomic cloud geometry in the scattering process, demonstrating that by controlling the cloud geometry it is possible to reduce multiple scattering and consequently enhance the coherence time of the scattered light. Finally, we theoretically explore signatures of collective effects in the Rabi oscillation dynamics of strongly driven, interacting two-level systems, revealing a collective displacement of the resonance frequency that increases with the optical depth of the system.

This master’s thesis is a continuation of a research project conducted with financial support from the National Council for Scientific and Technological Development (CNPq) in 2020, titled “Ora-Yê-Yê-Ô: or Black Beauty: From Discursive Re-signification to the Empowerment of Black Women.” In that initial research, we focused on analyzing the discursive functioning of technogeneres (posts, hashtags, photomontages, and videos) mobilized by Black women’s collectives on Web 2.0, with the aim of reframing the discursive aggression they face. In this work, the main objective is to promote dialogue between theoretical proposals on reframing (Paveau, 2021; Paveau, Costa, and Baronas, 2021) and discursive revascularization (Baronas and Costa, 2022; Baronas, 2024), developed in conjunction with the concept of intercomprehension (Maingueneau, 1984/2008). Based on a theoretical dialogue between the aforementioned concepts, we analyze how the history of Black beauty in Brazil is constructed, drawing a comparison with the issue of racial controversy fueled by hate speech on social media, using the theme of “Black women’s beauty” as a framework for reflection. Based on these analyses, we seek to understand not only how these women, who have been historically silenced, reframe the offenses directed against them, but also how certain groups reiterate previously produced aggressive statements, reproducing a racist and sexist viewpoint. Finally, this research aligns with the militant practices of reparation and historical resistance that these collectives promote in the digital sphere.

The issue of the school professional support has been a recurring theme in legislation, regulations, and legal proceedings, reflecting the tensions and contradictions between the declaration of right and its implementation. In this regard, the overall objective of this study was to analyze the right to a school support professional for students with disabilities and autism, as well as the judicialization process as a contradictory factor hindering its implementation, in the state of São Paulo, considering István Mészáros’s concepts of State, Law, and Education. The following specific objectives were defined: a) to situate the context of guaranteeing the right to a school support professional, based on István Mészáros’s categories of State, Law, and Education; b) to characterize the judicialization of the right to a school support professional as an expression of the contradictions in Special Education policy; c) to interpret the normative frameworks of São Paulo’s Special Education policy regarding school support professionals for students with disabilities and/or autism, considering the discontinuities and ruptures throughout the period from 2012 to 2024. The definition of these objectives replied to the following question: What model of special education is taking shape in the state of São Paulo, when analyzing the right to a professional providing academic support for students with disabilities and autism, and the contradictions revealed by the judicialization of this issue in light of István Mészáros’s understanding of the State, Law, and Education? The theoretical and methodological framework adopted was Historical and Dialectical Materialism, with István Mészáros as the primary theoretical reference. This is a documentary study grounded in the principles of policy analysis. The corpus of analysis consisted of documents obtained from the official websites Secretaria de Educação do Estado de São Paulo (Seduc); Conselho Estadual de Educação do Estado de São Paulo (CEE – SP); Fundação para o Desenvolvimento da Educação (FDE); Assembleia Legislativa do Estado de São Paulo (Alesp); Ministério Público de São Paulo (MPSP) e Defensoria Pública do Estado de São Paulo (Dpesp). These data were supplemented with statistics obtained from the websites of the Instituto Nacional de Estudos e Pesquisas Educacionais Anísio Teixeira, (INEP), Portal Datajud (Datajud-Wiki; Painel de Estatísticas) e Portal da Fazenda Pública do Estado. Microsoft Excel© and Atlas.ti© were used to organize and systematize the data; Mendeley Reference Manager© was used for bibliographic referencing. The results point to reformist trends, with the existing structures remaining intact. There is intense regulatory activity, combined with a persistent shortage of professionals. Government responses ignore the structural dimension, resulting in fragmented, partial, and targeted services at the expense of universal policies. Judicial intervention has functioned effectively; mediating students’ demands in relation to the state executive branch. There are aspects of structural anachronism, which maintain service models that do not meet students’ needs, as well as neoliberal principles, in which the state assumes the role of manager, outsourcing services and transferring responsibilities. These results indicate a model of Special Education strongly rooted in reformist and neoliberal practices, which affirm rights but maintain the structures.

In recent decades, Brazil and Catalonia—an autonomous community in Spain—have developed educational policies concerning the recognition of sign languages and the schooling of deaf students. In this context, this research aims to provide a comparative analysis of how selected legal and normative documents from Brazil and Catalonia (Spain) address bilingual education for the deaf, as well as the role assigned to deaf educators within this process. This is a qualitative study, grounded in the field of comparative education and conducted through a document analysis of official legislation and regulations pertaining to the education of the deaf in the contexts under investigation. The analysis examines aspects related to the recognition of sign languages, the organization of bilingual education, professional training, and the inclusion of deaf educators in educational policies. The study is based on historical-cultural theory—drawing, in particular, on the contributions of Vygotsky—which views language and social interactions as essential elements for human development and the construction of knowledge. Through the analysis of the selected documents, the research sought to identify similarities, differences, and gaps between the contexts studied, while accounting for their respective historical, political, and educational specificities. The findings indicate that the recognition of sign languages and bilingual education is not necessarily accompanied by an explicit definition of the deaf educator as a primary pedagogical, linguistic, and cultural reference point in the schooling of deaf students. In the Brazilian context—notably following the enactment of Law No. 14.191/2021— There is a more robust normative consolidation of bilingual education for the deaf, which includes the recognition of Libras (Brazilian Sign Language) as a first language and written Portuguese as a second language. In Catalonia, the documents analyzed reveal the presence of sign language within educational policies aimed at the schooling and inclusion of deaf students; however, there is no corresponding, explicit definition of the deaf educator as a specific professional role within bilingual education. A comparative analysis thus highlights both similarities and differences across the contexts investigated, as well as persistent gaps regarding the definition of the responsibilities, training, and role of the deaf educator within educational policies.

The COVID-19 pandemic constituted a global health catastrophe, whose psychosocial impacts disproportionately affected vulnerable populations, including children. Among the mental disorders that gained prominence during the pandemic period, childhood depression holds a relevant place, with consequences that can extend throughout development. This doctoral thesis aimed to investigate the effects of a psychosocial intervention in reducing depression symptoms among children exposed to catastrophe contexts, taking the COVID-19 pandemic as a reference. To this end, three interrelated studies were conducted. The first study evaluated the psychometric properties of the Children's Depression Inventory (CDI) in its 20-item version. The results indicated high internal consistency for the total score (α = 0.88) and for the affective (α = 0.79) and cognitive (α = 0.74) subscales, but unsatisfactory consistency in the behavioral (α = 0.52) and somatic (α = 0.49) subscales. Confirmatory factor analysis demonstrated adequate fit of the four-factor model (CFI = 0.99; TLI = 0.99; RMSEA = 0.000). The second study, with a quasi-experimental design including control and experimental groups and pre- and post-intervention measures, examined the efficacy of the ConViver program in reducing depressive symptoms. The results showed a significant reduction in symptoms over time for the entire sample (F(1,114) = 11.83; p = 0.0008), especially in the affective and cognitive dimensions, but without significant differences between the experimental and control groups. Stratified analyses revealed that girls in both the experimental and control groups showed greater symptom reduction and that non-Black children in the experimental group benefited more from the intervention than Black children. The third study, whose aim was to conduct a cluster analysis based on the change score identified in depression symptoms before and after the intervention (ΔCDI = T2 − T1), identified three trajectory profiles: Improved (n = 47), Stable (n = 46), and Worsened (n = 23). There was no significant association between allocation group and cluster membership (p = 0.641; Cramer's V = 0.00), indicating that the program did not significantly alter the normative trajectory of depressive symptoms. Multinomial logistic regression revealed that male gender was the only significant predictor of a lower chance of improvement (OR = 0.29; 95% CI: 0.12–0.73). Taken together, the findings indicate that the CDI is an adequate instrument for screening depressive symptoms in Brazilian children exposed to catastrophes, although its behavioral and somatic subscales require revision. The ConViver program, while not proving effective for reducing depressive symptoms, fulfills a relevant role as a mental health promotion and prevention intervention, acting on protective factors such as positive affect and support networks. The 13 improvement observed in some children appears to be explained by the normative course of the disorder and by the beneficial effects of school reopening and the resumption of social bonds in the post-pandemic period. The results reinforce the need for specialized interventions for established depressive conditions and point to the importance of an intersectional perspective in the implementation of psychosocial programs.

Seasonally inundated environments perform essential ecological functions for biodiversity conservation, flood mitigation, and hydrogeomorphological stability. In this context, the seasonal high-water channel constitutes an important technical reference for the protective delineation of riparian ecosystems. Despite its relevance, legal reforms have replaced this parameter with simplified geometric criteria due, among other factors, to claims regarding the impracticability of objectively delineating such areas. This study aimed to map the methods, indicators, and concepts employed in the delineation of seasonally inundated areas and to analyze their implications for environmental management and land-use planning. A scoping review was conducted following the PRISMA-ScR protocol, combining searches across five scientific databases with reference and citation tracking strategies, resulting in a total of 46 analyzed studies. The findings demonstrated that substantial terminological dispersion hinders both the understanding and protection of these environments and enabled the organization of the identified methods into three methodological groups according to their predominant mode of accessing the inundation phenomenon: hydrogeomorphological approaches, which interpret persistent physical and biological evidence preserved in the landscape; multitemporal remote sensing, which empirically records the occurrence and spatial extent of flooding over time; and hydraulic modeling, which projects potential scenarios under different hydrological conditions. This classification demonstrates that each group captures a complementary dimension of the phenomenon, highlighting that methodological integration through the convergence of multiple lines of evidence enhances the technical consistency of delineation processes and strengthens environmental decision-making in protected areas, while also providing technical support for the application of the in dubio pro natura principle under conditions of uncertainty. Based on these findings, a technical product was developed consisting of a proposed technical resolution and an operational protocol structured into progressive levels of analysis, intended to support environmental licensing, enforcement, and territorial planning procedures, with emphasis on methodological integration, traceability of technical decisions, context-sensitive application, and explicit documentation of uncertainties.
