This dissertation investigated Freud's conception of sadism and masochism between 1905 and 1919, first questioning whether such formations constitute particular pathological expressions or structural dimensions of human sexuality. The research examined the conceptual genealogy of the sadism-masochism pair, from its formulation in Richard von Krafft-Ebing's "Psychopathia Sexualis" (1886) to its reformulation by Freud in "Three Essays on the Theory of Sexuality" (1905). It demonstrated how Freud shifted sadism and masochism from the psychiatric field to conceive them as structural components of instinctual life. Perversion ceased to be understood solely as a pathological deviation and came to designate constitutive modalities of infantile sexuality and psychic organization. Sadism and masochism thus emerge as privileged expressions of the articulation between aggression, pleasure, pain, activity, and passivity, anticipating economic issues later developed in "Beyond the Pleasure Principle" (1920). The dissertation also analyzed Freud's additions to the "Three Essays" (1905) and the essays "Instincts and Their Vicissitudes" (1915) and "A Child Is Being Beaten" (1919). It was observed that, by incorporating concepts such as ambivalence, sadistic-anal organization, guilt, and the Oedipus complex, Freud broadens the metapsychological status of these formations. Masochism, therefore, ceases to be conceived merely as a derivation of sadism and comes to occupy a structural position in the constitution of subjectivity and moral consciousness. It can be concluded that sadism and masochism have become fundamental conceptual operators in Freudian drive theory, demonstrating that perversion is not external to normality, but a constitutive component of human experience.

This doctoral thesis investigates how the contemporary Brazilian far right, between 2019 and 2022, produced and consolidated an intersubjectively shared universe of meaning that conferred social plausibility upon the dismantling of environmental policy and the erosion of Indigenous rights. Although such processes are not unprecedented in the country’s history, the analysis focuses on the ways in which they were rearticulated and intensified during the Bolsonaro administration. Grounded in Alfred Schutz’s social phenomenology, the study starts from the assumption that social reality is constituted within the life-world through typifications, systems of relevance, and reciprocal expectations that orient action and delimit the horizons of the possible and the legitimate. The central hypothesis argues that the environmental and Indigenous policies implemented during the period under analysis cannot be reduced to circumstantial administrative or legislative choices; rather, they participated in the consolidation of a finite province of meaning within which environmental depletion and the suppression of Indigenous rights gradually came to be naturalized and collectively legitimized as socially acceptable practices. This interpretation is empirically supported by a qualitative examination of normative acts, administrative reforms, official speeches, and documents produced by socio-environmental and Indigenous organizations. By articulating these elements, the study seeks to understand narratives that deny the environmental crisis and Indigenous rights as a specific mode of ordering social experience, materialized in invisible cartographies that silence, hierarchize, and delimit territories of belonging and exclusion. In this sense, the title of the thesis refers to the constitution of territories of denialism, understood as social spaces of taken-for-grantedness in which criteria of plausibility and patterns of legitimation are stabilized, orienting practices, discourses, and public policies within the contemporary Brazilian far right.

Powder pressing followed by sintering is widely used in industry. In low-confinement stages, such as die ejection, handling, and green machining, the mechanical behavior of the green compact can be described by an elastoplastic constitutive model based on the Drucker-Prager (DP) yield criterion, incorporating isotropic hardening. This study investigated the identifiability of the linear DP model parameters with Voce hardening law, which include the elastic modulus (E), internal friction angle (β), yield stress (σy), saturation stress (σ∞), and hardening parameter (b), using cyclic Brazilian test data on alumina green compacts, adopting an associative plastic flow hypothesis (ψ = β). The Finite Element Model Updating (FEMU) technique was employed in two stages: a numerical sensitivity analysis based on synthetic data and a force-based experimental application (FEMU-F) using experimental data of three Brazilian tests available in the literature. The numerical analysis demonstrated that global force data enables the identification of E and β with high sensitivity but are unable to uniquely constrain the hardening parameters due to a critical coupling between σy, σ∞, and b, creating a valley of indistinguishable solutions. The incorporation of displacement fields in the combined approach (FEMU-UF) proved capable of mitigating this ill-conditioning, numerically validating the cyclic Brazilian test as a viable setup for elastoplastic characterization. In the experimental application, E and β were identified with a variability of less than 4%, while σy exhibited a variability of 38%, experimentally confirming the coupling predicted by the Hessian eigenvalue decomposition. Despite this parametric instability, a generalized model using average parameters reproduced the force-time curves with less than a 7% deviation compared to the individual fits. In conclusion, the model reproduces faithfully the mechanical response of the Brazilian test. Nevertheless, its global predictive capacity remains limited to the specific test conditions and the adopted hypothesis of associative flow.

The research addresses the challenges and prospects of regulating Artificial Intelligence (AI) in a constantly changing society. Situated within the field of Science, Technology and Society (STS), it begins with a reflection on data protection and informational self-determination, advancing to explore the ethical and social implications of AI in light of the absence of a specific regulatory framework in Brazil.The study seeks to understand how bills currently under discussion, such as Bill No. 2338/2023, may shape the future regulation of AI, promoting a risk-based approach that considers social vulnerabilities and fundamental rights. The choice of the term mutation in the title reflects the unpredictability and complex impacts of AI, which, like a genetic mutation, can bring both progress and challenges. The research examines how AI is already integrated into social, political, and economic spheres, not only through process automation, but also through systems capable of learning, predicting, and making decisions. This integration brings benefits such as efficiency and innovation, yet also poses structural risks, including the depersonalization of labor relations and the weakening of social protections. Through a qualitative and comparative analysis, the study examines the proposals for AI regulation, such as Bills No. 21/2020 and 2338/2023, comparing them with international models, particularly the European Union’s Artificial Intelligence Act. The conclusion highlights the urgency of developing an adaptive and responsive regulatory framework, capable of keeping pace with technological advances while preserving human centrality in automated decision-making. Thus, this research contributes to the STS field by proposing ethical and regulatory guidelines that aim to balance innovation, social responsibility, and the protection of fundamental rights.

Hospitals are complex organizations in which processes and sectors are interconnected. The Surgical Center (SC) is one of the most relevant hospital sectors, as it concentrates high care demand, intensive use of resources, and directly impacts patient flow. In this context, measuring operational times is essential for monitoring the efficiency of the sector, including admission time, anesthesia time, surgical procedure time, post-anesthetic recovery time, and total patient stay in the Surgical Center. Prolonged surgical flow times may lead to delays in subsequent procedures, increased operational costs, staff overload, and negative impacts on patient experience. This study aimed to propose the implementation of Lean Healthcare tools to reduce patient length of stay in the Surgical Center, based on the analysis of the care flow and the identification of the main causes related to prolonged process times. This is a qualitative study developed through a single and in-depth case study at the Surgical Center of Hospital Universitário Júlio Muller, in Cuiabá, Mato Grosso, Brazil. An exploratory literature review was also conducted to identify waste related to surgical processes. Data collection was performed through the analysis of records related to admission, anesthesia, surgery start and end, post-anesthetic recovery, and discharge times, in addition to direct observation of the surgical flow and interviews with professionals involved in the surgical process, including surgeons, anesthesiologists, nurses, nursing technicians, and residents. A total of 85 elective surgical procedures were analyzed. Data were organized in digital spreadsheets and submitted to descriptive statistical analysis using means and standard deviations for each stage of the process. The results showed an average patient stay in the Surgical Center of 6h18min (±2h06min). The average admission time was 39 minutes (±18 min), anesthesia time 3h09min (±1h39min), surgical time 2h01min (±1h31min), and post-anesthetic recovery time 1h44min (±51 min). The main sources of waste identified included communication failures among teams, delays in room preparation, unavailability of materials, and lack of process standardization. As improvement proposals, Lean Healthcare tools were applied, including Value Stream Mapping (VSM), Ishikawa Diagram, 5W2H method, Kaizen, and multidisciplinary “bate-mapa” meetings. The Future State VSM demonstrated the potential reduction of total Lead Time from 5h44min to 5h10min, mainly associated with the reduction of non-value-added activities and improvement in communication between sectors. It was concluded that the application of Lean Healthcare tools proved promising for identifying waste, optimizing surgical processes, and improving operational efficiency in the Surgical Center, contributing to greater predictability of care flow, reduction of delays, and strengthening of patient care quality and safety.

This thesis investigates how the concept of sustainability is constructed within scientific journalism and to what extent this construction aligns with the scientific concept discussed within the academic community. The study focuses on journalistic reports produced by three journalists from Revista Pesquisa Fapesp, analysed through Discursive Textual Analysis, as well as interviews conducted with these authors. The results indicate that, in the scientific journalism analysed, sustainability is predominantly associated with technology, understood as a means of increasing efficiency in the use of natural resources and as a central solution to environmental problems. This construction is strongly linked to the economic sphere, as the financial viability of technologies emerges as a relevant criterion for their legitimation as sustainable. Such a conception shows convergence with the scientific understanding disseminated by international organisations, particularly with regard to the less burdensome use of resources, while also revealing the circulation of a hegemonic view of the concept, reproduced by scientists frequently mobilised as sources. A largely unproblematised trust in science was also observed, marked by the absence of methodological discussion and by the transformation of estimates into expectations, which limits the potential for critical reflection among non-specialists. The interviews indicate that, although the journalists share elements of the scientific concept of sustainability, they also express criticism of its reduction to economic logic and the marginalisation of the social dimension. Finally, a shift was identified from a future oriented understanding of sustainability to one focused on present demands, aligned with the prevailing economic model. It is concluded that scientific journalism tends to present sustainability as a predominantly environmental and technological issue, pointing to the need to broaden the debate through practices that incorporate other actors and perspectives in the construction of this concept.

This thesis analyzes working conditions in Brazilian Public Rural Extension through the lens of digital mediations, selecting the category of work in its Marxist basis as the central analytical axis. The general objective consists of investigating how the incorporation of Digital Information and Communication Technologies (DICTs) reconfigures the material, organizational, and ontological dimensions of extension practice. The research starts from the hypothesis that the digitalization of Technical Assistance and Rural Extension (Ater) is driven by an institutional technological fetishism that, by presenting tools as neutral and self-sufficient solutions, can mask processes of precarization and labor intensification. The theoretical framework sought to establish a dialogue between the critique of political economy (alienation and precarization) and the field of Science, Technology, and Society (STS), mobilizing concepts such as surveillance capitalism and social technology. Methodologically, a mixed-methods approach was adopted based on a national quantitative survey conducted via a Google Forms questionnaire, with 475 valid responses from extension workers across 23 institutions, alongside a qualitative content analysis (Bardin) of the open-ended reports. The results indicate a scenario of contradiction, in which digitalization expands the territorial reach of actions, streamlines communication, and enables new forms of technical monitoring and guidance, but also intensifies work, extends working hours beyond formal schedules, reinforces control mechanisms through targets and system records, and contributes to processes of overload and loss of autonomy. In this context, digital technologies fulfill a dual role: they enhance communication and service provision while also dissolving the boundaries between work time and personal life, imposing permanent connectivity and subordinating practice to monitoring and registration systems. This process is interpreted as a contemporary expression of precarization and alienation in extension work. The analysis identifies, however, the emergence of the "Ethics of Commitment" as active resistance, in which extension workers appropriate DICTs as Social Technology for the guarantee of rights and rural citizenship. As a propositional contribution, the thesis advocates for the regulation of the right to disconnect, the material valorization of professionals, and the subordination of technique to social and territorial objectives. It is concluded that strengthening public Rural Extension requires overcoming the technological and managerialist fetish, reaffirming the extension worker as an agent of transformation and an active presence in the territories.

This dissertation investigates how the curricula of pre-service Biology teacher education programs (Licenciatura) at the Federal University of São Carlos (UFSCar), Brazil, articulate the curricular status of phylogenetic systematics and tree thinking in initial teacher education. The empirical materials consist of the Course Curricular Projects (Projetos Pedagógicos de Curso, PPCs), treated as curriculum documents that frame and organize curricular knowledge. This qualitative documentary study compares seven PPC versions from the Araras, São Carlos, and Sorocaba campuses, including Araras (2007), São Carlos (2015, 2025), Sorocaba full-time (2010, 2023), and Sorocaba evening (2008, 2022). The corpus was analyzed through Discursive Textual Analysis (DTA), articulating unitarization, categorization, and the production of an interpretive metatext, with the reading guided by four analytical categories: formative rationalities in teacher education, mechanisms of theory–practice integration, the curricular status of phylogeny, and epistemological and pedagogical coherence. The findings indicate that phylogeny appears with variable intensity as a recognized scientific language and content within the core disciplinary subjects, especially in syllabi and bibliographies, and that recent reforms, particularly in Sorocaba, institutionalize foundational systematics as mandatory components of the curriculum. At the same time, curricular prescription does not transform phylogenetic systematics, treated primarily as content, into phylogenetic literacy or into tree-thinking operations, since tree thinking remains absent from the intended graduate profile and expected competencies and is not articulated in longitudinal teaching-practice components or in the teaching practicum. In PPCs that explicitly state evolution as an integrating axis, there is likewise no indication of tree thinking as an organizing principle for biological content and biological reasoning. This dissertation argues that phylogeny as content and phylogenetic literacy as a teaching competence correspond to distinct regimes of curricular prescription. The former is sustained by disciplinary presence and distribution, whereas the latter depends on decisions regarding compulsory status, timing and sequencing, and curricular textual specification that make possible the acquisition of tree-thinking operations throughout the program. Finally, the study proposes directions for curricular redesign aimed at institutionalizing these operations as organizing principles for Biology teaching.

In survival analysis, it is common to incorporate covariates such as age, sex, disease severity, among others. However, there are several unobserved factors that may also influence survival, including overall health status, lifestyle, occupation, or genetic predisposition. Such factors are often referred to as frailty and represent unobserved heterogeneity among individuals in the study. The objective of this work is to develop frailty models capable of capturing this unobserved heterogeneity in survival data. We introduce a new class of survival models that combines population unobserved heterogeneity and the presence of cured individuals through the incorporation of frailty terms from the PVF family (Power Variance Functions), referred to as PVF-Induced Defective (PVF-ID) models. This framework extends the classical theory of frailty models and defective lifetime models, allowing researchers to flexibly model the presence of long-term survivors. Inference is performed through a fully Bayesian procedure implemented via Hamiltonian Monte Carlo, while relevant frequentist properties are assessed through simulation studies. When applied to survival data related to HIV/AIDS, the model consistently identifies the effects of the covariates. Additionally, a bivariate survival model with cure fraction and frailty is proposed, based on Poisson mixtures and the PVF family. The model is extended to a regression framework, allowing the assessment of covariate effects on survival times. Inference is conducted under a Bayesian approach using Hamiltonian Monte Carlo implemented in RStan, and simulation studies are carried out to evaluate the performance of the estimators. The flexibility of the proposed structure allows the model to capture both dependence between failure times and unobserved heterogeneity. The practical utility of the model is illustrated using a real dataset.

Surface engineering has become an essential field for understanding how topographical characteristics influence the functional performance of materials in different applications, such as heat exchangers. Therefore, investigating the relationship between manufacturing parameters, machining vibrations, and variations in surface roughness parameters has attracted increasing scientific and technological interest. In this context, vibrations induced by actuators or inherent to machining processes can significantly alter surface morphology, resulting in surfaces with distinct characteristics depending on the process conditions. Thus, the present work aims to characterize flat machined surfaces of aluminum, brass, and stainless steel produced through turning and milling processes under different machining conditions, with emphasis on the analysis of roughness and wettability parameters. The characterization of the surface topology of the samples was carried out using confocal microscopy, evaluating the parameters of average roughness (Ra), skewness (Rsk), and kurtosis (Rku). Wettability analyses were performed using an optical tensiometer, enabling measurements of static, advancing, and receding contact angles, with distilled water used as the working fluid. The results obtained from turning indicated that, for all analyzed materials, samples produced under more severe machining parameters exhibited higher contact angles compared to surfaces manufactured under milder conditions. In contrast, the opposite behavior was observed for aluminum samples produced by milling, where higher contact angle values were associated with the higher speed condition corresponding to unstable machining. Overall, a consistent association was observed between the behavior of the skewness parameter and static contact angles, since in several cases where skewness varied, variations in static contact angle were also observed. These results contribute to the understanding of the influence of vibrations on the topographical characteristics of machined surfaces, supporting the correlation between manufacturing conditions, surface roughness, and wettability.

This paper analyzes the transformations in the conceptions of control of the main companies in the Brazilian meatpacking companies: JBS, Marfrig, and Minerva, addressing how their strategies and management models were reconfigured in the context of the sector's consolidation and the financialization of the economy. The theoretical framework is based on Fligstein's economic sociology, especially the notion of conceptions of control. It engages with the literature on financialization and the Varieties of Capitalism approach, situating the Brazilian case within its specific institutional arrangement. It starts from the premise that conceptions of control express internal power dynamics within companies and their position in a field marked by disputes, state mediation, and market pressures. Methodologically, a multiple case study approach was adopted, analyzing the trajectory of the companies based on documentary analysis of corporate reports and corporate documents from 2007 to 2024. The investigation focused on dimensions such as acquisitions and mergers, shareholding composition, capital structure and leverage, profiles of the board of directors and management boards, and dividend distribution, allowing for a processual understanding of organizational transformations. The results indicate that the expansion of the companies, which became dominant in the national market and protagonists in the global protein trade, was driven by growth strategies via mergers and acquisitions, financed by leveraged capital structures and access to the stock market. The initial public offering (IPO) represented a turning point, redefining performance criteria and expanding the influence of institutional investors. A progressive professionalization of management and a reconfiguration of the role of the founding families were observed, in an environment increasingly driven by financial metrics. In terms of control concepts, the consolidation of shareholder value orientation was identified as the dominant principle throughout the analyzed period. The dynamics of the sector thus reveal a field of strategic action in which the State, companies, and investors interact, highlighting a hybrid form of financialization in Brazilian capitalism. It is concluded that the transformations in the conceptions of control of these corporations express broader changes in the organization of agro-export capitalism in Brazil, contributing to a critical understanding of financialization in emerging economies and its effects on governance and business action.

In this research, conducted in the area of the Heliópolis favela and the São João Clímaco neighborhood (southern zone of São Paulo), an ethnographic study was carried out on the effects of the national policy of recent decades aimed at combating precarious settlements – understood from the development of the Favela Urbanization Program – specifically its housing and social interventions. To achieve this objective, the thesis is structured into five chapters that articulate theoretical, documentary, and ethnographic analysis. The first chapter ethnographically reconstructs the formation of the field of urban studies, demonstrating how the central lens defining favelas as spaces of precarious housing was consolidated, focusing on the theoretical/discursive bases that would later be assimilated by the national public housing policy studied. The second chapter specifically examines the transition of this alignment between the theory of urbanization (of large cities) and housing policies, analyzing the theoretical-political fold through which the critical diagnosis of the unequal city – forged in the struggles against the military dictatorship – was converted into housing management technology, focusing on the description of how this academic knowledge underpinned the national policy to combat precarious settlements in urban Brazil (materialized in the Favela Urbanization Program). The third chapter introduces the ethnographic perspective of the research field, describing the historical action of residents who formed the local social movement in the Heliópolis region and their influence on the territorialization of the Favela Urbanization Program's intervention, explaining how local housing struggles were both recognized and resignified by the Program. The fourth chapter complicates this understanding by presenting other voices, knowledges, and housing arrangements that escaped the standardizing planning of the Favela Urbanization Program, pointing to the diversity and complexity of the ways of living in the favela that were obscured by the housing intervention studied. Finally, the fifth chapter focuses on the concrete experience of removal and waiting resulting from the intervention, detailing ethnographically how the lives of residents of the studied area were transformed by forced displacement, dependence on housing assistance programs, and prolonged uncertainty regarding the housing promised with the development of the Favela Urbanization Program; which, according to statements gathered in the research, produced a new form of vulnerability. The research, based on intensive fieldwork and bibliographic and documentary research, made it possible to confront the official project of the city with the understandings of struggle held by the population objectified by that project. The thesis concludes that urban interventions such as the Favela Urbanization Program, by ignoring the complexity, history, and disputes inherent in the ways of living in favelas, not only fail to solve housing problems but often intensify them, demanding from favela residents constant reinventions of their struggles for the right to housing and to live in the city.

Analyzing institutional politics in Brazil requires an examination of its past as a means to understand the present and envision possibilities for "other futures." It is fundamental, therefore, to recover the profiles of representatives who have occupied decision-making spaces and to identify the interests and objectives that permeated the sphere of institutional political representation. Consequently, understanding the profiles of city councillors (vereadores) in Sorocaba/SP, within a timeframe beginning in 1948, constitutes the central object of this thesis, which seeks clues to understand institutional political dynamics.The focus on Sorocaba’s local legislature is configured not merely as a research possibility, but as a recovery of the author's own political trajectory within the city. This lived experience becomes an investigative tool intertwined with scientific research, structured under rigorous sociodemographic analysis, fieldwork, and theoretical foundation. Thus, examining the locality from this perspective serves as a strategy to identify potential generalizations that assist in understanding electoral dynamics at state, national, and global levels. The recovery of these dynamics at the territorial level allows for an understanding of the vestiges of the roots that forge the relations between representatives and the represented. The identification of phenomena such as coronelismo (colonelism), mandonismo (bossism), and clientelism - and their developments through the lenses of the "legislator," the "procurer," and the "welfare provider" - comprises the framework chosen by the author to categorize, based on semi-structured interviews, the councillors elected for the first time in the 2024 elections. Furthermore, this study seeks to demonstrate how this modus operandi perpetuates itself, alongside the hypothesis of an emerging new group, termed by the author as the "personalist" group. This profile does not necessarily maintain a bond with the territory, a party project, or a political party; rather, it fosters a direct identification with the voter through themes that transcend local jurisdiction and the traditional role of the councillor, mediated primarily by social networks. Finally, the study reflects upon the profiles of councillors in Sorocaba/SP, emphasizing variables such as gender, race, religion, and marital status, in search of investigative evidence on how these new profiles may reorganize the dynamics of institutional politics.

A proteólise intracelular em eucariotos é mediada principalmente pelo Sistema Ubiquitina–Proteassoma (SUP), que envolve as enzimas E1, E2 e E3, sendo estas últimas responsáveis pelo reconhecimento dos substratos. Em protozoários parasitos, como Leishmania infantum, o SUP é essencial para adaptação ao ciclo de vida e sucesso do parasitismo, embora ainda seja pouco explorado, especialmente as E3 ubiquitina-ligases. Este estudo teve como objetivo caracterizar bioquimicamente e funcionalmente as proteínas F-box-like LinfFlp2 (LINF_240015400) e LinfFlp3 (LINF_150014400), adaptadores da E3 ubiquitina ligase LinfCRL1 de L. infantum. Parasitos expressando LinfFLP2-HA e LinfFLP3-HA foram submetidos à imunoprecipitação seguida de espectrometria de massas para identificação de proteínas associadas. Os interactomas revelaram 44 proteínas exclusivas para LinfFlp2, 125 para LinfFlp3 e 106 proteínas compartilhadas nos interactomas de LinfFlp2 e LinfFlp3, sugerindo redundância funcional. Para validação das interações em células HEK293T, os genes Replication protein A subunit (LINF_280024500), RNA-binding protein 29 – putative (LINF_180007200), Leucine-rich repeat protein – putative (LINF_340011100) e Putative mitochondrial carrier protein (LINF_020012000) foram clonados em vetores para expressão em células de mamíferos em fusão com myc no N-terminal. Ensaios de co-imunoprecipitação demonstraram que a proteína LRR é um potencial ligante de LinfFlp3. Em L. infantum, demonstramos através de CRISPR-Cas9 que as linhagens nocaute de LinfFLP2 não resultou em impacto no crescimento promastigota, enquanto não foi possível obter o nocaute completo de LinfFLP3, sugerindo caráter essencial. A inserção de uma cópia de LinfFLP3-HA no locus 18S ribossomal do parasito e posterior nocaute das duas cópias genômicas resultou em linhagem viável (DKO-LinfFLP3-HA), reforçando a essencialidade deste gene para L. infantum. O nocaute de uma das cópias do gene SKO LinfFLP3, DKO-LinfFLP3-HA e LinfFLP2-HA não apresentou alteração significativa de crescimento e não observamos alteração nas fases do ciclo celular das linhagens SKO-LinfFLP3 ou DKO-LinfFLP3-HA. Finalmente, análises de microscopia confocal demonstraram que LinfFlp2 e LinfFlp3 apresentam distribuição predominantemente citoplasmática granular e perinuclear com sutil localização nuclear. Em conjunto, os dados sugerem redundância funcional entre LinfFlp2 e LinfFlp3, ampliando a compreensão das LinfFlps na biologia de L. infantum.

This study aims to investigate the resistance capacity of high-strength steel composite cellular beams with concrete slabs against web-post buckling. To this end, nonlinear geometric and material analyses were performed using the ABAQUS® software. The numerical model was validated against experimental data from physical models of composite cellular beams with concrete slabs. Four reference models were used as a basis for a parametric study carried out in two stages. In the first stage, the influence of the steel yield strength was investigated for S460, S690, and S960 steels (with yield strengths of 460 MPa, 690 MPa, and 960 MPa, respectively), without geometric variations. In the second stage, variations in steel strength were combined with variations in the following ratios: the opening diameter to the unexpanded steel profile height (Do/d), taking values of 0.8, 0.9, 1.0, and 1.1; and the center-to-center spacing to opening diameter ratio (p/Do), taking values of 1.2, 1.3, 1.4, and 1.5. For the variations of the validated symmetric profile models, CCB1 from Nadjai et al. (2007) and CCB3 from Müller et al. (2006), as well as the asymmetric model CCB2 (asymmetry ratio of 1.13) also from Nadjai et al. (2007), web-post buckling remained the predominant failure mode across all steel grades during the first stage, with maximum strength gains ranging from 24.6% to 60.8% for S690 and from 54.0% to 83.4% for S960. For variations of model CCB4, also from Müller et al., (2006), which has a top-to-bottom tee asymmetry ratio of 2.8, only local web buckling of the top tee was observed in the first stage, regardless of yield strength, with strength gains of 28% for S690 and 68% for S960. In the second stage, increasing Do/d tended to reduce the maximum strength, while increasing p/Do generally increased it, although complex interactions between geometry and steel yield strength were observed. For the CCB1, CCB2, and CCB3 variations, as steel strength increased, failure modes shifted toward those involving the formation of Vierendeel plastic mechanisms, either in isolation or combined with web-post buckling. For the CCB4 variations, the failure mode shifted from pure local web buckling of the top tee to an interaction between this failure mode and the Vierendeel plastic mechanism. The numerically obtained maximum strength values were compared with four analytical verification models: Panedpojaman et al. (2014), Grilo et al. (2018), AISC Steel Design Guide 31 (2016), and BS EN 1993-1-13 (2024). The comparison shows that most formulations underestimate the maximum resistance capacity of high-strength steel–concrete composite cellular beams. When analyzing the effect of increasing steel yield strength on maximum strength, the AISC Steel Design Guide 31 (2016) method showed an increase in the F_numerical/F_analytical ratio, while the other methods showed a decrease in this ratio as strength increased. Furthermore, all methods exhibited high coefficients of variation, often exceeding 40%, indicating high relative data dispersion. This level of variability compromises the reliability of predictions for high-strength steels, suggesting that current formulations do not adequately capture the instability and plastification phenomena in composite cellular beams with high-strength steel profiles.

The detection of microplastics in dairy matrices presents complex analytical challenges due to the density of lipids and proteins. Given these technical limitations, this research shifted the investigative focus from end-product analysis to mapping vulnerabilities within the production process. The objective of this study was to identify and evaluate critical points of microplastic contamination in the cheese manufacturing chain using a qualitative and descriptive approach. The methodology consisted of a comparative case study involving industrial units in Brazil and three strategic hubs in the European Union: the Netherlands, Spain, and Italy. The results allowed for the categorization of risks based on mechanical, thermal, and chemical stresses of polymers in contact with food. It was identified that extreme automation (Netherlands) and pressing time (Spain) are relevant vectors, but the highest criticality lies in industrial slicing and grating (Italy), where the increased plastic-to-food contact area enhances physical migration. The study concludes that the Brazilian regulatory framework presents a "blind spot" by focusing primarily on chemical stability while neglecting the physical degradation of equipment. The adoption of preventive replacement protocols for polymeric materials is recommended to mitigate the accidental ingestion of microparticles by consumers.

Operant conditioning has become established as a strategic tool in the management of wild animals kept in ex situ conservation programs. This study investigated the practical application of operant conditioning in Brazilian institutions (zoos, wildlife triage and rehabilitation centers, breeding facilities, among others), analyzing the profile of training protocols, their purposes, and the technical limitations faced. The methodology consisted of a literature review and the application of a diagnostic form, preceded by a pilot study to validate and refine the instrument, which was subsequently applied to 201 institutions, of which 29 responded (30 including the pilot).The results indicate that operant conditioning is widely used in Brazilian ex situ conservation institutions, being implemented in 70% of the participants and under development in an additional 16.7%. Its application is mainly concentrated on large mammals and birds, particularly felids, primates, and psittacine, revealing marked taxonomic selectivity to the detriment of reptiles and invertebrates. Operant conditioning is primarily employed to facilitate daily and veterinary management, promote animal welfare, and reduce the need for physical and chemical restraint, with a predominance of positive reinforcement techniques. Although most institutions report having trained professionals, the lack of specialized technical training and the absence of systematic behavioral assessments, such as the use of ethograms, represent significant limitations. It is concluded that, despite its strong potential as a management and conservation tool in Brazil, operant conditioning still requires greater technical standardization and broader taxonomic application to be consolidated as a robust strategy for animal welfare, rehabilitation, and wildlife release.

The present study investigated the ethics of love and its inseparability from occupational therapy care. Far removed from romantic or charitable meanings, love is understood as a feeling-action with political and transformative power, capable of confronting the violence and oppression that permeate subjects and populations historically marginalized. The research analyzed interviews with occupational therapists, interpreted through thematic analysis. Two themes emerged, demonstrating how loving practices strengthen relationships, promote objective and subjective transformations—both individual and collective—and sustain the struggle against violence present in the lives of individuals and communities. Although recognized as essential, love remains stigmatized and is often associated with fragility or seen as incompatible with technique and professionalism. The results indicate that it must be assumed as an ethical and political force, capable of fostering horizontal relationships, affirming diversity, and resisting oppressive logics. In Occupational Therapy, the ethics of love appears as a condition for humanized and transformative care, shifting professional practice away from rigid protocols toward actions committed to life, dignity, and social justice. To embrace it as an ethic transversal to the caring professions is to affirm its collective, community-based, and liberatory dimension. “Politics of love” thus become an inspiration for sustaining the well-being of all beings—human or non-human—and for recognizing care as a practice of freedom.

This dissertation analyzes 400 offensive political memes shared during the 2022 Brazilian electoral period on the social media platform X (formerly Twitter). In addition to investigating the discursive dynamics present in these contents, the study proposes a methodological update for the analysis of offensive political memes by incorporating specific categories of political attack into the taxonomy traditionally used in this type of research. The objective is to understand how these memes, particularly those focused on the Brazilian political scenario, seek to validate their respective ideologies by discrediting opponents and delegitimizing opposing discourses through offense. The research considers memes as multimodal discursive and cultural artifacts embedded within the context of contemporary digital culture and, at the same time, is grounded in an Information Science perspective that understands information as a thing, treating memes as documents. From this perspective, memes cease to be merely ephemeral content and instead become evidence of knowledge, values, and cultural and political practices shared by social groups. Initially, a theoretical review was conducted tracing the shift in the concept of the meme from its origins in memetic theory to its appropriation by communication and digital culture studies in the form of called internet memes. Following this review, the characteristics of the database used were presented, and the curation procedures guiding the analytical construction were described, including the stages of classification and cataloging of the memes. For the analysis, a typological content model was initially adopted, classifying political memes according to three main categories subdivided into twelve subcategories. The empirical analysis, however, revealed limitations in this taxonomy when it became necessary to capture certain forms of attack present in the corpus. In response to this limitation, the research proposed an update to the analytical model, incorporating new categories related to political attack strategies, namely accusation, morality, fake news, and violence. The results demonstrate significant discursive differences between the political spectrums analyzed: while memes associated with the left tend to concentrate on strategies of ridicule, political humor, and symbolic moralization, memes linked to the right show a higher incidence of accusation and content classified as fake news. This expansion makes it possible to refine the analysis of offensive political memes, more accurately understand the discursive dynamics involved in the circulation of such content in digital environments and offer methodological contributions for future studies on digital political communication, participatory culture, and meme analysis.

This dissertation analyzes the materialization of national educational policies aimed at ensuring access, retention, and completion of Basic Education for deaf students and/or students with hearing impairment in the municipality of João Pessoa, Paraíba, Brazil, from 2008 to 2023. The study is grounded on the assumption that, although the Brazilian legal framework has significantly advanced in recognizing the educational rights of this population especially through the strengthening of inclusive education and bilingual education perspectives structural and institutional challenges continue to limit the effective implementation of these rights throughout students’ educational trajectories. The guiding research problem seeks to understand how inclusive and bilingual policies have contributed, in terms of access, retention, and completion, to the educational trajectories of thirteen cohorts of deaf students enrolled in Basic Education in João Pessoa (PB) in 2008 and followed until 2023. The general objective was to analyze these students’ educational trajectories, identifying patterns of regularity, irregularity, and interruption, as well as the impacts produced by educational policies throughout the period under investigation. Methodologically, this is a quantitative longitudinal study based on the analysis of microdata from the School Census produced by the National Institute for Educational Studies and Research Anísio Teixeira (Inep). Enrollment tracking was conducted through the Protected Data Access Service (Sedap), enabling the individual monitoring of 183 students identified as deaf and/or with hearing impairment, distributed across thirteen cohorts, from Early Childhood Education to the third year of Upper Secondary Education. The variables analyzed included promotion, grade repetition, dropout, migration to Youth and Adult Education (EJA), and completion of Basic Education. The typologies of educational trajectories regular, slightly irregular, highly irregular, and interrupted were developed based on the proposal by Souza, Senkevics, and Rodrigues (2024), allowing the classification and description of school pathways over time. In addition, a documentary analysis of the normative framework supporting Brazilian educational policy was carried out, highlighting the Federal Constitution of 1988, the National Education Guidelines and Framework Law (LDB), the National Education Plan (PNE 2014–2024), the Brazilian Inclusion Law (LBI), Decree No. 5.626/2005, and Law No. 14.191/2021. This analysis discusses tensions between the context of policy production and the context of practice, revealing contradictions between legal advances and operational limitations in policy implementation within education systems. The results indicate that, although formal access to mainstream schooling has expanded, the educational trajectories of deaf students and/or students with hearing impairment remain marked by high levels of age-grade distortion, grade repetition, and dropout, particularly during transitions between educational stages, especially from lower secondary education to upper secondary education. Access has not consistently translated into sustained retention and completion, pointing to weaknesses in the implementation of inclusive and bilingual education policies, particularly regarding the pedagogical, linguistic, and institutional conditions required to guarantee the right to education. This dissertation contributes to the advancement of longitudinal studies on deaf education in Brazil by providing empirical evidence that highlights the gap between rights ensured at the normative level and the actual conditions of schooling. By exposing the limits of formal universalization, the study reinforces the need for public policies that articulate access, retention, meaningful learning, and completion, ensuring the full educational experience of deaf students within Basic Education.
