This dissertation presents the development of a low-cost platform for water quality monitoring, utilizing the Arduino UNO R3 microcontroller and an integration of commercial sensors. The proposed system aims to offer an accessible and efficient solution for collecting data on essential water parameters, such as temperature, electrical conductivity, pH, and turbidity. The work details the sensor integration methodology, the firmware developed for data acquisition and processing, and the modular architecture that allows for expansion to different application scenarios. The system was designed to be robust and easily replicable, contributing to the democratization of environmental monitoring and the early detection of changes in water quality. Although detailed validation and calibration results are still being obtained, the platform demonstrates the potential to be a valuable tool in environmental studies and water resource management.

Recent estimates indicate that the housing deficit in Brazil exceeds 6 million dwellings, driven by increasing urban population concentration and growing barriers to homeownership. This dissertation analyzes the methodology for calculating the housing deficit developed by the João Pinheiro Foundation (FJP), focusing on its application at the intracity scale. The research acknowledges the institutional relevance of this methodology but questions its conceptual, operational, and political limitations, especially in light of the socio-spatial inequalities that characterize Brazilian cities. The objective is to critically examine the FJP methodology using a qualitative and multiscalar approach, based on secondary data from the 2010 Demographic Census and local surveys conducted in the municipality of Jacareí-SP. The methodological framework includes a review of the housing deficit concept, a theoretical analysis of the FJP methodology, and its practical application to census microdata. The results indicate that the housing deficit is not a neutral absence, but a normative construct that determines who is or is not recognized as a subject of public policy. The analysis revealed limitations in the methodology when applied at the intermunicipal level - particularly through the use of census weighting areas - which obscures internal inequalities and phenomena such as overcrowding, excessive housing cost burden, and inadequate sanitation. The research also incorporated a sociodemographic and infrastructure analysis of deficit households, deepening the diagnostic beyond absolute housing numbers. The limitations encountered - such as the unavailability of 2022 census microdata and the rigidity of official tools - did not compromise the analysis, but rather reinforced the critique of relying solely on census data for urban planning. The study concludes that it is urgent to develop local strategies for housing monitoring based on integrated, multiscalar, and territory-sensitive approaches. This dissertation thus seeks to contribute to the improvement of housing public policies, grounded in fairer, more sensitive, and territorially qualified diagnostics.

Soil carbon stock is a crucial indicator of soil health and an important component of climate‑change mitigation, being directly influenced by land‑use and management practices. Low‑carbon agriculture seeks to reconcile food production with environmental sustainability, aligning with commitments to reduce greenhouse‑gas emissions. This study primarily aimed to evaluate the spatial variability of soil carbon stock (SCS) in the 0–60 cm layer among Integrated Livestock–Forest (IPF), Cropland, and Pasture systems, and to analyze the relationship between total carbon and soil physicochemical variables. Soil samples were collected at depths of 0–20, 20–40, and 40–60 cm, and analyses were performed to determine a range of physicochemical attributes. Principal Component Analysis (PCA) was used to identify the attributes that most contributed to variability in soil properties among management systems. Subsequently, Spearman’s correlation analysis was applied to test the association between total carbon and soil attributes within each system. Means of soil carbon stock were statistically compared using the nonparametric Mann–Whitney test (p < 0.05). PCA results indicated that attributes such as aluminum saturation, exchangeable aluminum, organic matter (OM), pH, and base cations (calcium, magnesium, potassium), in addition to textural fractions and sulfur, were the main determinants of variability in soil attributes across the evaluated systems. The correlation analysis showed that OM had the strongest positive and significant correlation with total carbon in all managements (IPF, Cropland, and Pasture). In contrast, aluminum and aluminum saturation consistently displayed negative correlations with carbon. Correlations for other attributes varied among systems: sand correlated negatively in Cropland and Pasture but not in IPF, and potassium showed no significant correlation in Pasture. For soil carbon stocks (0–60 cm), Cropland had the highest mean (117.22 t ha⁻¹), followed by IPF (107.5 t ha⁻¹) and Pasture (93.17 t ha⁻¹), revealing that SCS differs statistically among systems, depending on management and each area’s physicochemical characteristics. Cropland and IPF systems demonstrated greater potential to maintain or increase soil carbon compared with Pasture in the study area. Organic matter is the primary factor influencing soil carbon stock across all managements, reinforcing the importance of agricultural practices aimed at building OM for the sustainability of agroecosystems.

Background: Temporomandibular disorder (TMD) is a complex musculoskeletal condition often causes orofacial pain, functional limitations, and otological symptoms. Specific cervical exercises and manual therapy are widely used strategies for managing TMD-related symptoms; however, their effects on otologic symptoms remain unclear. Aerobic exercise, despite its therapeutic potential for musculoskeletal pain, is still underexplored in this population. Objectives: This thesis investigated the effectiveness and clinical relevance of physiotherapy interventions involving manual therapy and specific cervical exercises, alone or in combination with aerobic training, on orofacial pain, neck disability, and otological symptoms in women with chronic TMD. The specific aims were: (1) to analyze the effectiveness of manual therapy and therapeutic exercises on otologic symptoms in individuals with TMD through a systematic review (Article 1); (2) to evaluate the additional effects of aerobic training to cervical exercises on orofacial pain, neck disability, and related outcomes in a randomized controlled trial (Article 2); (3) to assess whether otological symptoms secondary to TMD improve after isolated cervical exercises or combined with aerobic training (Article 3); and (4) to determine the clinical relevance of the effects of these interventions using distribution- and anchor-based methods, with a focus on the minimal important difference (MID) (Article 4). Methods: The thesis comprised a systematic review and a randomized controlled trial. The systematic review included studies that evaluated the effects of manual therapy and exercises on otological symptoms in individuals with TMD, with certainty of evidence assessed using the GRADE approach. The randomized controlled trial enrolled 58 women with chronic TMD, allocated to two groups: (1) cervical exercises (strengthening and stretching of flexors, extensors, and rotators, and spinal mobility) and (2) cervical exercises combined with aerobic treadmill training. The intervention lasted eight weeks, with two sessions per week. Outcomes included orofacial pain, neck disability, otological symptoms, mandibular function, oral health-related quality of life, self-efficacy, and pressure pain thresholds of masticatory and cervical muscles. Statistical analyses included repeated-measures models, multilevel modeling (MLM), and estimation of the MID using distribution- and anchor-based methods. Results: The systematic review found that combining exercises with manual therapy may improve otological symptoms in individuals with TMD, but the certainty of evidence was low. In the clinical trial, no statistically significant differences were found between groups. However, both groups showed significant within-group improvements in pain, neck disability, otological symptoms, mandibular function, quality of life, and self-efficacy. Effect sizes were generally larger in the group that combined cervical and aerobic exercises. Otological symptoms significantly decreased in both groups, with clinically relevant reductions, particularly for tinnitus, earache, and ear fullness. Clinical relevance analysis showed that between-group differences did not reach the MID thresholds, whereas within-group effects were moderate to large. MID values ranged from 17.05 to 31.56 mm for pain intensity, and from 1.04 to 3.41 points for neck disability. Conclusion: Combining exercises with manual therapy may improve otological symptoms in individuals with TMD, though the certainty of evidence remains low. Adding aerobic training to specific cervical exercises did not yield additional benefits in reducing orofacial pain or otological symptoms in women with TMD. This thesis provides evidence on the effectiveness of these interventions and offers clinically relevant parameters to support evidence-based practice and patient-centered decision-making.

In this PhD thesis, we investigate div-curl type estimates associated with linear partial differential operators on Hardy-Sobolev spaces. The main result establishes a local extension of div-curl estimates for elliptic homogeneous linear partial differential operators with smooth complex coefficients in localizable Hardy-Sobolev spaces, inspired by the classical result due to Coifman, Lions, Meyer and Semmes. This version recovers known results in the literature concerning first-order operators associated with elliptic systems of complex vector fields. As key tools, we develop a new Calderón-Zygmund decomposition and a Poincaré-type inequality in localizable Hardy-Sobolev spaces. A second main result presents a global nonhomogeneous version of div-curl type estimates in the localizable Hardy space for p = 1, associated with complex vector fields with constant coefficients. As an application, we provide a new characterization of the local bmo space in Euclidean space associated with div-curl terms.

Printed Circuit Boards (PCBs) are important components of electrical and electronic equipment. Due to their composition, which includes materials of high value as well as others with potential hazards to the environment and human health, they have become the focus of growing concern. The present work analyzed strategies for end-of-life management of printed circuit boards (PCBs) in Brazil, integrating a systematic literature review, modeling for the prediction of waste electrical and electronic equipment (WEEE), and scenario assessment using Life Cycle Assessment (LCA). The significant increase in publications addressing hydrometallurgical methods for metal recovery from PCBs has highlighted the potential for sending them to recycling processes. However, gaps such as recovery processes through biometallurgy and the management of reverse logistics still need to be explored, pointing to opportunities for future research. Forecasting WEEE generation in Latin America proved to be essential, where per capita GDP and Human Development Index (HDI) were used as variables. The generated model showed that economic and social development directly impact the quantity of waste generated, reinforcing the importance of specific public policies for the management of WEEE reverse logistics. The possible end-of-life scenarios for PCBs were evaluated using the LCA technique, and the results indicated that a recycling plant in Brazil, based on the acidic hydrometallurgical method, would be the most sustainable solution among the scenarios evaluated. The recovery of precious metals, such as gold and palladium, proved to be fundamental for reducing environmental impacts and generating economic value by reinserting materials into the production cycle, while processing in Brazil minimizes the impacts associated with transport to other countries, as currently occurs. This work contributes to the advancement of sustainable management of reverse logistics of electronic waste by providing well-founded support for public policies and business initiatives, reinforcing the importance of regional strategies and investments in innovative technologies to promote a circular economy.

The search for sustainability has become an essential condition for the preservation of life. Climate change and natural disasters have increasingly highlighted the urgency of balancing development and environmental conservation, which has led the Brazilian government to expand its legal framework and invest in programs aimed at raising awareness and mitigating adverse impacts.The Environmental Agenda in Public Administration (A3P) is a program created by the Ministry of the Environment, which aims to encourage public agencies in the country to implement sustainability practices. Considering the importance of Higher Education Institutions (HEIs) in the production and dissemination of knowledge, as well as their social influence, this research aims to investigate the theme of environmental management on the campuses of the Federal Institute of São Paulo (IFSP), conducting an analysis of the sustainable actions implemented on the different campuses of the institution based on the axs that make up the Environmental Agenda in Public Administration (A3P). The research is classified as exploratory and descriptive, with a quantitative approach, outlined as a survey, of an applied nature. Data collection was conducted thru the application of a questionnaire and supplemented by documentary research and the gathering of information from the IFSP campuses' websites. The research results indicate that the IFSP campuses that participated in the study partially comply with the guidelines proposed by the Environmental Agenda in Public Administration. However, some challenges need to be faced, especially regarding the consolidation and awareness of sustainability committees, as well as the adoption, in the different campuses of the institution, of the actions and events of good environmental practices proposed by the IFSP Sustainability Plan.

Changes in rainfall can affect the structure of ecological communities, influencing the interactions amongst trophic levels. In terrestrial tritrophic systems involving herbivores such as immature Lepidoptera, their host plants and parasitoids, these changes are very complex and hard to predict, especially in the tropical Atlantic rainforest. Since the knowledge about species distribution and seasonal patterns are necessary for conservation efforts, the main objective of this work is to evaluate the temporal variation in the community structure of immature Lepidoptera associated with Myrsine L. species and their interactions with parasitoids in an atlantic rainforest area. The study was conducted at the Reserva Biologica da Serra do Japi, in the township of Jundiaí, São Paulo state, Brazil. From March to August 2024, Immature Lepidoptera were sampled with an entomological umbrella in 33 host plants, distributed in two species of the family Primulaceae: Myrsine umbellata (N=19) and Myrsine gardneriana (N=14). The immature lepidopterans were taken to the Instituto Nacional de Ciência e Tecnologia dos Hymenoptera Parasitoides (INCT-HYMPAR) in the town of São Carlos, SP, and were kept under laboratory conditions until the emergence of Adult Lepidoptera or eventual parasitoids. The specimens were deposited at the Coleção Taxonômica do Departamento de Ecologia e Biologia Evolutiva, Universidade Federal de São Carlos, Brazil (DCBU). In total, 215 larvae of Lepidoptera were recorded, distributed in 8 families (Erebidae, Geometridae, Limacodidae, Noctuidae, Psychidae, Riodinidae, Saturniidae and Tortricidae) and 46 species and morphospecies. Phrygionis polita was the most abundant species (N=46). Richness and Diversity values were higher for the dry season and the early dry season had the higher sample coverage. Immature abundance was statistically consistent over time (p=0,86084). There was a significant variation in the species composition (p=0.0116) and the variation was mostly explained by the higher abundances of some species in the early dry season. A total of 131 parasitoids were reared, belonging to two orders (Hymenoptera and Diptera), 4 families and 19 morphospecies. A new species of the genus Colpotrochia Holmgren was recorded and described. Parasitism proportion differed between seasons and was higher in the dry season; changes in the trophic interactions were also observed. Thus, this work provides new ecological data and reinforces the importance of studies with immature Lepidoptera for conservation.

The VIMAC3V steel, which is a variation of the High-Speed Steel M3:2 according to ASTM A600, belongs to the category of high molybdenum content High-Speed Steels (M class) and includes alloying elements such as chromium, vanadium, and tungsten. It stands out for its exceptional wear resistance combined with toughness and hot hardness, making it suitable for various industrial tools such as taps, reamers, knives, dies, and punches. However, due to the high number of precipitated carbides in the matrix, VIMAC3V steel exhibits high resistance to abrasive wear during the machining of the final tool, resulting in low grindability when compared to other steels in the same class. This limitation has the potential to negatively impact productivity and increase industrial costs. Thus, this study was divided into two parts. The first part involved the characterization of commercial steels from different suppliers. The objective of this phase was to correlate the microstructure with the best combinations of properties for the application of this material. The results obtained from the characterization of commercial steels showed finer and more homogeneously distributed carbides, as well as relevant changes in the chemical composition of the material. The second phase consisted of implementing changes in the manufacturing process of this material to obtain an optimized microstructure based on the results obtained in the first phase. The studies focused on chemical composition analysis, microstructure, carbide quantification, types of inclusions, and wear resistance. The main microstructural feature observed was the distribution of the present carbides which demonstrated a significant improvement in the distribution and size of carbides. Therefore, it was concluded that the applied changes were effective and provided insights to understand and propose improvements in the microstructure toward refined carbides.

Competitive and Technological Intelligence (CTI) emerges as a methodological alternative for technology-based ventures, encompassing the collection, processing, and automated analysis of technological information from patent documents. This approach aims to capitalize on opportunities and mitigate threats in the competitive environment, effectively directing strategies. The objective of this research was to investigate the use of patent analysis by Competitive and Technological Intelligence in the context of the competitive processes of technology-based ventures. The methodology adopted is classified as a metric, exploratory, and quantitative-qualitative study, using categorical content analysis and bibliometric techniques. The sample consisted of 90 article records indexed in the Web of Science database, representing the intersection between the topics of patent analysis (6,326 documents) and competitive/technological intelligence (4,046 documents). The results achieved include a set of indicators: 1) characterization of the analyzed sample; 2) indicators on patent analysis; 3) indicators on Technological Competitive Intelligence; 4] analysis of the characteristics of patent analysis appropriation by Competitive and Technological Intelligence, including insights into trends and patterns. The conclusion is that patent analysis plays an essential role in supporting Competitive and Technological Intelligence, providing strategic information for innovation and decision-making in technology-based companies. However, the limited intersection between studies on both topics indicates the need for greater methodological integration and in-depth research on the topic. It is recommended that future research explore new analytical approaches and expand the practical application of these concepts across different industrial sectors, promoting better use of patent data in developing competitive strategies.

Since the redemocratization, public security policies in Brazil have undergone successive legal and institutional reforms, driven by recurring crises and social pressure for more effective responses to crime and violence. These transformations reflect not only conjunctural reactions but also ideological disputes regarding the roles assigned to the State, punishment, and protection in the implementation of public policies. Based on this context, the study recognizes that the post-1988 period was marked by distinct political-ideological orientations, delimiting the research timeframe between 1995 and 2022. This interval encompasses a phase of relative democratic stability and three blocks of institutional change: the liberal pattern during the governments of Fernando Henrique Cardoso, the neo-developmentalist pattern under Lula and Dilma Rousseff’s administrations, and the pattern of democratic regression observed during the governments of Michel Temer and Jair Bolsonaro. In this light, this research proposes to investigate, from the tension between the paradigms of punishment and protection, how and in which direction public security policies were modified throughout this period. The analysis combines David Garland’s (2001) typology of state models of crime control, its application to the Brazilian context by Azevedo and Cifali (2015), and the framework of gradual institutional change developed by Streeck and Thelen (2005) and systematized by Mahoney and Thelen (2010). This combined approach allows not only for identifying and classifying normative changes – from penal toughening to the approval of prevention policies and rights guarantees – but also for understanding how incremental adjustments gradually shift the axis of public policies between punitive and protective rationalities. The research integrates two complementary movements – one theoretical-historical and the other empirical – using a database of 60 approved laws, which were initially analyzed quantitatively and later subjected to qualitative content analysis, focusing on 9 laws identified as substantive policies in the field. The thesis of misalignment emerges, according to which the relationship between the ideological profile of governments and the type of policy adopted is not linear, highlighting the complexity of institutional arrangements and normative disputes shaping the public security field. Nonetheless, the study points out that public security policies primarily change through layering. The analysis seeks to reveal the ideological vectors underlying these transformations and, by demonstrating how specific normative decisions accumulate effects over time, contributes to Political Science by offering a deep understanding of the reconfiguration of the State’s role in addressing crime and insecurity management in contemporary Brazil.

Alzheimer’s disease (AD) is the most prevalent neurodegenerative disorder worldwide, affecting approximately 50 million people, with an average life expectancy of 5 to 10 years after symptom onset. As life expectancy increases, so does the incidence of AD, leading to significant social and economic burdens, especially on public healthcare systems. From a neuropathological perspective, the main hallmark of AD is the presence of senile plaques composed of toxic aggregates of the β-amyloid peptide (βA40/42), which disrupt cellular homeostasis and damage neuronal structures. Evidence suggests that soluble oligomeric species of βA are the primary agents of toxicity, preceding the formation of mature fibrils. Given this context, it is essential to explore strategies that can interfere with βA aggregation and enable its detection at early stages. Metal complexes have emerged as promising tools, acting both as aggregation inhibitors and as luminescent probes for early diagnosis, overcoming the limitations of traditional markers such as Thioflavin T (ThT), which only detects fibrillar species. In this work, the complex [Ru(phen)₂(pNDpI)](PF₆)2 (RuNDI) was synthesized and characterized with the aim of evaluating its potential as an inhibitor and probe for the aggregation process of the βA₁₋₄₂ peptide. The complex was characterized by mass spectrometry, UV-vis absorption, and steady-state luminescence spectroscopy. It features a straightforward three-step synthesis, high yield, and good solubility in physiological media. Spectroscopic properties—such as strong absorption in the visible region (λₘₐₓ = 450 nm, ε = 13,000 L·mol⁻¹·cm⁻¹), broad emission centered at 610 nm, and a large Stokes shift (5.55 × 10³ cm⁻¹) — highlight its suitability as a luminescent probe for biological applications, with minimal interference from biomolecule absorption and negligible reabsorption of emitted light. βA₁₋₄₂ aggregation studies were conducted using complementary techniques, including fluorescence, circular dichroism, FTIR, and atomic force microscopy. Interaction analyses with RuNDI demonstrated its potential as a luminescent probe for detecting intermediate species formed during peptide aggregation. Comparisons with ThT revealed similar interaction mechanisms, but with advantages linked to RuNDI's spectroscopic features, such as a larger Stokes shift and emission in regions with reduced biological autofluorescence. Furthermore, at concentrations higher than that of the peptide, the complex was able to modulate β-sheet formation and inhibit the progression toward mature fibrils. These findings position RuNDI as a promising tool for investigating the molecular mechanisms underlying the development of Alzheimer’s disease.

Considering the municipality of Socorro, Sao Paulo state, with its strong tourism potential and agricultural vocation, this research examines the synergies between rural tourism and agroecology as an alternative for adding value to family farming. The methodology combined a bibliometric analysis with structured and semi-structured interviews conducted with smallholders. The bibliometric analysis revealed a growing theoretical interest after 2018, highlighting tourism’s potential for generating income and promoting environmental and cultural preservation. The interviews likewise recognized its economic, social, and ecological potential, but also pointed to practical challenges such as labor availability, infrastructure, and time constraints. The study concludes that tourism represents a viable opportunity for value addition, but its success depends on careful planning, supportive policies, and attention to local specificities.

Binary regression models are excellent modeling approaches for dichotomous data, allowing us to relate the probability of the event of interest to the available covariates. In this type of scenario, it is common to encounter data imbalance, that is, a proportion of zeros (or ones) significantly different from ones (or zeros), which makes symmetric link functions poor alternatives when fitting the model. In this work, we propose a class of binary regression models fitted with asymmetric link functions, namely: the power and reverse power link functions. Additionally, we incorporate spatial random effects into our regression, thereby assuming that the binary data can be spatially referenced. The resulting binary regression becomes a special type of Bayesian hierarchical model whose spatial structure is modeled through a more flexible prior distribution than the standard CAR (Conditional Autoregressive) model: the G-Wishart prior distribution. Through a motivational dataset, we present an extension of the proposed spatial binary regression model. For both models, we provide simulation studies and applications to real data, as well as a Bayesian analysis for the detection of influential points. Parameter estimation is fully Bayesian, with a focus on maximizing computational efficiency during the estimation process. The performance of the models proposed herein will be assessed and compared using Bayesian diagnostic metrics and predictive quality measures. The performance of our algorithm will be evaluated through computational simulations and applications to real-world datasets. Finally, as a preliminary and motivational perspective, we present a simulation study using the DAGAR spatial model.

This thesis investigates, from the perspective of political economy and the historical-dialectical method, the influence of the World Bank (WB) on the regulatory policies of Brazilian public higher education, focusing on the dissemination of the World-Class Universities (WCU) model. The study is based on the premise that the consolidation of this international paradigm does not arise from voluntary adaptations or isolated administrative choices, but rather emerges from a complex process forged by transnational power networks and mediated by technical, symbolic, and financial devices that permeate the institutional fabric of Brazilian universities. Centering the analysis on academic labor, regulation, and subordination, the research critically articulates the historical trajectory of the WB, the reconfiguration of the social role of the public university, and the rise of a rationality oriented toward excellence, competitiveness, and integration into global evaluation circuits. The investigation draws on a corpus composed of eight paradigmatic WB reports, national higher education legislation, and guiding documents, analyzed through concepts such as totality, historicity, contradiction, mediation, hegemony, and alienation, engaging throughout the text with classic and contemporary authors of international reference. The analysis shows that the adoption of the WCU model introduced heteronomous forms of regulation, reorganizing not only curricular structures and university management, but also research, teaching practices, and academic labor relations, fostering the centralization of decision-making power, institutional standardization, and the commodification of knowledge. The study demonstrates that the influence of the WB materializes as a vector of structural reconfiguration, never reducible to a merely technical or disinterested act; on the contrary, it shapes an architecture of subordination in which the Brazilian public university is called to serve the interests of global financial capital, often to the detriment of social demands and national development projects. Pressures for internationalization, rankings, technological innovation, and corporate partnerships turn the university into a showcase of results and a laboratory of institutional adaptation, eroding its critical social function and autonomy. The research reveals that such transformations do not occur through direct imposition, but through symbolic, technical, and political mechanisms that permeate institutional and everyday practices, altering meanings, priorities, and actions. Ultimately, the thesis answers the central question affirmatively, demonstrating that the World Bank exerts decisive, multifaceted, and often covert influence over the transformation of Brazilian public universities into world-class institutions, with profound repercussions for academic labor, citizenship formation, the social role of the university, and the future of national public higher education.

América Latina se caracteriza por diversos intentos de homogeneización de las interpretaciones del mundo, a partir de una lógica dominante que refuerza las estructuras de opresión en la sociedad. En la ciudad de São Paulo, la periferia popular se ha consolidado en una realidad compleja, en la medida en que la planificación urbana no ha respondido a sus demandas en diferentes momentos históricos. Este contexto forma parte de la realidad del colectivo “Mulheres do GAU (Grupo de Agricultura Urbana)”, con el que esta investigación promueve investigaciones y diálogos. En diversos contextos latinoamericanos, la Educación Popular se consolida como praxis educativa, afirmándose en la lucha por la justicia social. En esta perspectiva, la investigación tiene como objetivo comprender y problematizar los procesos educativos revelados por la práctica social de la agricultura urbana realizada por las “Mulheres do GAU”, buscando comprender las contribuciones de estos procesos educativos y cómo las mujeres interpretan el espacio urbano en el que actúan. La investigación es de naturaleza cualitativa y la metodología adoptada es la investigación participante, en la que la convivencia dialógica con el colectivo fue fundamental. La producción de datos se realizó mediante la observación participante, entrevistas semiestructuradas y círculos de conversación. La información fue recopilada e interpretada mediante el análisis de contenido. Los resultados muestran cómo las “Mulheres do GAU”, a través de la agricultura urbana, abordan situaciones límite y deshumanizantes, como la discriminación por motivos de género y raza, la exclusión urbana y los desafíos de ser agricultora en la ciudad. Y así, anuncian diversos procesos educativos, tales como el reconocimiento de sus voces; la ampliación de sus lecturas del mundo; la acogida; la cooperación; los intercambios de conocimientos; la comprensión de cómo lidiar con los conflictos; el sentimiento de pertenencia; el respeto y el amor por la naturaleza, que incluye a los seres humanos y no humanos; el reconocimiento de su trabajo; y cómo sus experiencias de vida constituyen sus formas de ser agricultoras urbanas. También enseñan y aprenden a ser esperanzadas, en el sentido de señalar caminos para hacer las cosas de manera diferente, reivindicando posibilidades de humanización en el trabajo. Con la conclusión de esta investigación, esperamos haber contribuido a la comprensión del universo de la agricultura urbana en la ciudad de São Paulo, practicada por mujeres, en su mayoría negras, profundizando las discusiones sobre las resistencias y las luchas por la calidad de vida en las periferias populares.

This study investigated the level of development of empathic active listening skills among public servants at the Center for Exact Sciences and Technology of the Federal University of São Carlos (CCET/UFSCar). Empathic active listening is a form of listening motivated by the desire to understand others through active engagement, mindfulness, and empathic comprehension. Techniques associated with empathic active listening skills contribute to improved interpersonal communication, making it a required skill for all public servants. In this context, this study aimed to measure the development of empathic active listening skills among public servants at the Center for Exact Sciences and Technology of UFSCar. To answer the research question and understand the measurement of empathic active listening, an integrative literature review was conducted to identify scales for measuring this skill. This study used the Empathic Active Listening Scale (AELS), a selfreport scale comprising three dimensions: detection, processing, and response, along with the listening skills subscale and the opportunity for conversation from the Active Listening Attitude Scale (ALAS). Data were analyzed using exploratory factor analysis. Statistical analysis of the data showed that the CCET/UFSCar presents a moderate level of empathic active listening skills and that the associations between faculty and administrative staff, and between Engineering and Exact Sciences, show the same level of development. The results of this study demonstrated the importance of empathic active listening in the development of interpersonal communication among public servants and the importance of providing training for the development of empathic active listening in the public service. This study contributed to the literature by studying empathic active listening skills among public servants at a Center for Exact Sciences and Technology of a federal university, filling an academic gap. From a practical standpoint, this research presents an empirical diagnosis of the level of development of empathetic active listening skills among public servants. As a technological product, this study developed a conclusive technical report demonstrating the level of development of public servants at CCET/UFSCar.

This thesis proposes and substantiates the concept of critical media education as a structural response to systemic disinformation, understood not as an occasional deviation but as a phenomenon that is functional to surveillance capitalism and the instrumental rationality that shapes digital platforms. It differs from notions such as media literacy, educommunication or competence-based models by defending critical media education as a distinct category, anchored in ethical-political foundations and in a critique of informational power structures. Grounded in the Critical Theory of Society (especially Adorno, Horkheimer, Benjamin and Marcuse), the research mobilises the concepts of semiformation and damaged life to explain the vulnerability of subjects to manipulative narratives in a digital environment that reinforces a technical, adaptive and uncritical form of education. The central objective is to analyse, from a theoretical and documentary perspective, how critical formative practices can enable citizens to resist algorithmic logics, the attention economy and symbolic manipulation that permeate the contemporary informational ecosystem. Methodologically, this is a qualitative, theoretical and analytical study, based on a literature review and documentary analysis of public policies and media education programmes in Brazil, Finland and the United Kingdom, with UNESCO’s formulations as an additional reference. The results indicate that, although documents such as the National Common Curricular Base (BNCC) and the Brazilian Media Education Strategy represent important advances, structural challenges remain, such as regional inequalities, fragile federative coordination and gaps in teacher education. The thesis concludes that only a critical media education capable of denaturalising technologies, problematising algorithms and reading disinformation as an expression of the power asymmetries of surveillance capitalism can rebuild the link between education, emancipation and democracy. This requires robust public policies, continuous investment in the critical training of educators and intersectoral coordination that recognises critical media education as a human right and as an instrument of resistance to systemic disinformation.

The digitization of rare cultural heritage materials requires more than simple visual reproduction. It is essential that digitization occurs simultaneously with a detailed description of the object, including data on its production, provenance, and trajectory, ensuring the preservation of its context and historical relevance. Thus, the question arises: how has the description of rare materials in digital environments with Linked Data characteristics been discussed in the scientific literature of Information Science? The objective is to investigate initiatives for describing rare materials in digital environments from the perspective of Linked Data in the scientific literature of Information Science, in order to: a) analyze and present the state of the art on the description of rare materials in digital environments with Linked Data characteristics; b) present the standards for describing rare materials and identify their characteristics; c) map the standards, instruments, and initiatives for describing rare materials and their characteristics; d) present and analyze cases of description of rare materials in digital environments with Linked Data characteristics; e) identify similarities and differences in the structuring, representation, and description of rare materials in digital environments; and f) propose recommendations for the description of rare materials with Linked Data characteristics. The methodology used comprised a Systematic Literature Review and an empirical study. As a result, with the aim of studying the cases, initiatives, and instruments identified in the corpus in question, five general categories were established: Models for the representation and organization of bibliographic and cultural data, Ecosystem of tools and projects for data, Cataloging Tools and Standards, Semantic Resources, Spectrum of Metadata Schemas. The research analyzed 29 articles and identified 18 practical cases that demonstrated the conversion of traditional metadata (such as MARC) to semantic models (such as BIBFRAME) and its enrichment through connection with external controlled vocabularies. Recommendations were proposed for the description of rare materials, suggesting the adoption of flexible models (BIBFRAME), open vocabularies, and Web standards (such as JSON-LD and IIIF) to ensure interoperability and access to cultural heritage.
