This work presents a comparative analysis between classical and incremental path planning algorithms applied to the RoboCup Small Size League (SSL), an environment characterized by high dynamics, multiple robots, and frequent physical interactions among them. In this context, the choice of the path planner directly influences navigation safety, trajectory efficiency, and the overall team performance, which justifies the need for a structured evaluation of different approaches. The algorithms Dijkstra, A*, Lifelong Planning A (LPA*), and D* Lite were implemented and compared, all operating on the same Visibility Graph representation to ensure a common basis for analysis. The experiments reproduce typical game situations involving both static and dynamic obstacles, allowing the observation of how each method responds to varying levels of environmental demands. The evaluation combined qualitative visual analyses and quantitative performance metrics, along with full-match simulations, highlighting clear differences between classical and incremental planners, particularly regarding adaptation to environmental changes and collision occurrence. The results provide a consistent understanding of the advantages and limitations of each approach and offer practical support for selecting path planning strategies in mobile robotic systems operating under dynamic conditions.

This research aims to investigate and understand anxiety in the face of death in light of Freudian psychoanalytic theory, especially in conjunction with the formulations of the second theory of anxiety. It also seeks to understand how cultural structures mobilize to attribute meaning and manage this type of anxiety. To carry out the investigation, a historical overview of the subject's relationship with death in the West was constructed, as well as an analysis of the development of the notion of anxiety in the face of death in Freud's work. Next, the main metapsychological concepts related to it were explored in depth, namely: anxiety, helplessness, castration anxiety, anxiety in the face of the superego, and the constitution of the superego. The relationship between religion and death is also discussed, examining the origin of religious conceptions based on the experience of helplessness and nostalgia for the father figure, and the relationship between science and anxiety in the face of death, exploring the articulation between the death drive and the destruction drive and the role of science in enhancing the destruction of others through the development of military technologies. It is proposed that anxiety in the face of death is not reduced to an instinctive fear of biological extinction, but articulates psychic dimensions related to helplessness, loss of protection, and the instances that sustain the subject.

The presence of elemental impurities (EI) in medicines, such as heavy metals, represents a risk to human health due to their high toxicity even at low concentrations, and to ensure patient safety, it is essential to carry out a rigorous assessment of these contaminants. The international guideline ICH Q3D (International Council for Harmonisation Guideline Q3D: Guideline for Elemental Impurities) establishes PDE (Permitted Daily Exposure) limits based on toxicological data and the route of drug administration. In addition, chapters of the USP (United States Pharmacopeia) describe modern analytical techniques, such as ICP-MS (Inductively Coupled Plasma Mass Spectrometry) and ICP OES (Inductively Coupled Plasma Optical Emission Spectrometry), which allow for the detection and quantification of these impurities with high sensitivity, constituting an effective quality control system. In view of the need to identify and control inorganic contaminants originating from raw materials, manufacturing processes, equipment, and packaging in the final product, this work aims to develop a safe and validated analytical method using ICP-MS, through AQbD (Analytical Quality by Design), for the determination of the 24 elemental impurities controlled by the guideline in injectable-matrix pharmaceuticals. To achieve this objective, the ATP (Analytical Target Profile) was defined as a method capable of quantifying IE in injectable solutions, with an average and individual recovery percentage between 70 and 150%, RSD ≤ 20%, discovery curve scanning coefficient ≥ 0.99, and a detection limit greater than 0.2 J μg/L. If the method is capable of quantifying the element at concentrations equal to or lower than 30% of “J”, it may, in some cases, even eliminate the need for continuous monitoring. Next, a cause-and-effect (Ishikawa) diagram was developed with the aim of identifying the potential critical method parameters of the analytical procedure. These parameters were subsequently classified according to their risk using the FMEA (Failure Mode and Effects Analysis) tool, resulting in the selection of four experimental factors with the greatest potential impact on the analytical response: nebulizer gas flow (L/min), plasma power (W), acidity of the diluent solution (% HNO₃), and sample dilution factor. These factors were evaluated at three coded levels (–1, 0, +1), following an experimental design based on a CCD (Central Composite Design), implemented using the statistical software Minitab. The study generated a total of 155 experiments, aiming to model and understand variations in the analytical response resulting from intentional changes in the selected parameters. This approach sought to define the method’s MODR (Method Operable Design Region), within which analytical performance meets the criteria established in the ATP, ensuring robustness, precision, and reliability throughout the method’s lifecycle. The results obtained showed recovery values consistent with the applied spiking levels, falling close to the upper limit of the specification range (100%). Given the robustness, consistency, and analytical performance observed, it was concluded that the parameters defined in the DoE (Design of Experiments) are suitable for adoption as the definitive method, both for constructing analytical calibration curves and for sample preparation, ensuring reliability and reproducibility in subsequent processes.

This research aimed to analyze how the graphic novels Encruzilhada (2016) and Angola Janga: Kingdom of Runaway Slaves (2017), by Marcelo D’Salete, represent the experiences of racism and Black resistance in Brazil. We started from the premise that Black arts and aesthetics in general, and the graphic novels selected here specifically, are important contributions to understanding the social and cultural dynamics that shaped the Afro-Brazilian experience. Our investigation starts from the following sociological problem: in what way and with what tools do the comic books Encruzilhada and Angola Janga: Kingdom of Runaway Slaves, by Marcelo D’Salete, represent the experiences of racism and black resistance in Brazil? More specifically, we sought to: a) sociologically analyze the production process and the meanings of the artistic and narrative choices present in Angola Janga and Encruzilhada; b) explore how the interpretations and meanings deposited by the author in both productions challenge the predominant narratives about Afro-Brazilian history and experiences; and c) investigate how the works Encruzilhada and Angola Janga develop the categories of time and memory to illustrate Afro-Brazilian resistance and struggle. This research adopted a qualitative approach, using iconography and content analysis to explore the visual and narrative elements present in the works. In addition, an in-depth interview was conducted with the author Marcelo D'Salete. Overall, the research demonstrates that Encruzilhada (2016) and Angola Janga: Kingdom of Runaway Slaves (2017) constitute visual counter-narratives that reconfigure the representation of Afro-Brazilian experiences by moving black individuals from the historical condition of objects of violence to the position of agents of memory and resistance. Through aesthetic and narrative choices, D’Salete articulates the past and present, highlighting the continuities of the racist structures of Brazilian society and, at the same time, the strategies of black resistance.

This thesis investigates anti-Black racial bias as symbolic responding organized by social, cultural, and historical contingencies, proposing an integrated research agenda that combines conceptual analysis, evaluation of explicit and implicit measures, and experimental intervention studies. Chapter 1 presents the theoretical framework, defining racial prejudice as relational responding and discussing conceptual and methodological challenges in its measurement and modification. Chapter 2 provides a critical review of empirical research on anti-Black racial bias within Behavior Analysis, identifying gaps that guide the subsequent experimental studies. Chapter 3 focuses on the evaluation of racial bias measures. Study 2, conducted with children aged 8 to 10 years, examined the temporal stability of an explicit valence measure (Likert scale) and the Function Acquisition Speed Test (FAST), an implicit measure, using a repeated-measures design, demonstrating high stability and sensitivity of the FAST to anti-Black racial bias. Study 3, also with children aged 8 to 10 years, employed a multimodal analysis of racial prejudice, identifying a substantial gender effect characterized by the devaluation of Black women, as well as contextual variation in social preference, indicating contextual control of relational responding. Chapter 4 presents intervention studies with children based on the stimulus equivalence paradigm. Study 4, with children aged 8 to 10 years, replicated procedures described by Mizael et al. (2016, 2022), demonstrating the formation of equivalence classes between Black faces and positive stimuli, with reductions in negative relations and valence differences, albeit with limited generalization and social desirability effects. Study 5, with 6-year-old children, showed greater convergence across measures and partial generalization, though without stable maintenance for all participants. In Study 6, using word-based equivalence procedures and longitudinal follow-up, produced more robust generalization effects and evidence of social validity, although changes occurred gradually and heterogeneously, with varying patterns of relational flexibility and resistance to change. A common finding across Experiments 3, 4, and 6 was that the absence of equivalence class formation was associated with the absence of change in racial bias measures. Chapter 5 presents adult study. Study 7, conducted with 116 White Irish adults, evaluated the effects of different FAST-based training configurations on implicit and explicit measures, including a shooter task based on the Police Officer’s Dilemma Task, the Modern Racism Scale, and facial valence ratings. The stereotype-consistent condition exacerbated bias relative to the control condition, whereas the counter-stereotypical and flexibility conditions produced mitigating effects, with the former being the most effective. Overall, this dissertation contributes to a systematic research agenda on anti-Black racial bias, demonstrating that behavioral procedures can reorganize previously established classes while also delineating the possibilities and limits of modifying racial relational control across development and adulthood.

The Lattes Platform has established itself as a fundamental database for the production of Science and Technology indicators in the Brazilian context. Aiming to analyze academic inbreeding in the scientific co-authorships of researchers at the Federal University of São Carlos (UFSCar), this research developed an integrated computational procedure capable of coordinating different technologies for the extraction, treatment, processing, and visualization of bibliometric data. The methodology involved automated data collection from the Lattes Platform, metadata treatment through Python scripts, mapping of scientific co-authorship networks using a Java application, and the generation of visualizations with geolocation features. The analyzed dataset comprises 86,341 co-authorship records in full journal articles up to the year 2024, corresponding to 24,612 unique productions, involving 664 researchers from UFSCar – São Carlos Campus accredited in graduate programs, and 7,322 co-authors with professional addresses registered in the Lattes Curriculum. The results confirm the research hypothesis by showing that the developed procedure made explicit the collaboration relationships that are hidden in the standard interface of the Lattes Platform. Evidence indicates a predominance of non-inbred co-authorships and heterogeneity in inbreeding levels according to the unit of analysis, in addition to showing no linear associations between inbreeding and geographical distance. The research demonstrates the effectiveness of the computational procedure for the empirical diagnosis of academic inbreeding and highlights the potential of visualizations for analyzing the dynamics of scientific collaboration from an architectural and interdisciplinary perspective.

This research investigates how neoconservative female parliamentarians re-elected in 2022 update their agenda in the digital environment regarding themes related to gender equity following the defeat of President Jair Messias Bolsonaro. The general objective of the study is to analyze how these women instrumentalize female identity as a strategic resource to promote neoconservative political views and delegitimize gender equity policies. To this end, the Instagram profiles of Congresswomen Bia Kicis and Carla Zambelli, both from the Liberal Party (PL), are analyzed during the 2023-2024 biennium. The methodology is anchored in Computational Social Science, employing Natural Language Processing (NLP) techniques, social network analysis, and multimodal qualitative analysis. The results indicate that, contrary to the cooling-off hypothesis, the patriotic and nationalist agenda remains central, strategically merging with family and religion agendas. A division of discursive labor is observed: while Carla Zambelli mobilizes engagement through political and affective maternalism, Bia Kicis operates a strategic legalism to contest democratic institutions. It is concluded that the digital mandate of these parliamentarians instrumentalizes "womanhood" and moral panic as tools for base cohesion and the maintenance of gender hierarchies, adapting resiliently to the opposition context.

Parental burnout is a condition of physical, mental, and emotional exhaustion associated with chronic stress related to parenting responsibilities. Factors such as low social support, coparenting conflicts, and underdeveloped socioemotional skills appear to contribute to its development. This study investigated the relationship between parental, coparental, and marital skills and symptoms of parental burnout, as well as the effects of programs and materials focused on parenting and coparenting. A total of 247 mothers and fathers who had or had not participated in programs or accessed materials on these topics took part in the study. Instruments assessing parental burnout, coparenting relationship, parenting styles, and marital social skills were administered. In addition, 40 participants completed semi-structured interviews about coparenting and parental well-being. The results showed that coparental support and expressiveness and empathy skills predicted lower parental burnout scores. In contrast, coparental conflict, inconsistent punishment, lax discipline, physical abuse, and, surprisingly, assertive conversational skills and proactive self-control predicted higher burnout scores. Differences were also observed in coparenting relationship quality, marital social skills, and parental burnout symptoms between parents who had or had not participated in interventions and accessed parenting-related materials. The interviews highlighted the importance of the coparenting relationship for parental well-being. Despite limitations related to the sample and the diversity of the analyzed programs, the findings suggest that interventions aimed at strengthening coparental, parental, and marital skills may act as protective factors against parental burnout.

The Myrtaceae family stands out for its high diversity and ecological importance in the Cerrado, especially the genus Eugenia, which comprises numerous species with ecological significance and economic potential. Eugenia velutifolia Mazine & Sobral is a recently described species (2019), endemic to the São Paulo Cerrado and critically endangered, lacking information regarding its reproductive biology. This study aimed to expand morphological and taxonomic data, re-evaluate its conservation status, and evaluate the species' germination capacity. Fruits were collected in a Cerrado area located in the municipality of Salto de Pirapora (SP), and the collected material (voucher) was deposited in the SORO herbarium at the Federal University of São Carlos (UFSCar), Sorocaba campus. Morphological analyses were based on fieldcollected material and herbarium specimens. The germination test was conducted at the Seedling and Seed Laboratory (LaSem) at UFSCar. The morphological description of E. velutifolia was expanded to include data regarding the bracts, bracteoles, underground system and, primarily, the fruits and seeds, which had been unknown since its original description. The fruits are predominantly rounded, measuring 3.9–13.2 × 4.05–11.7 mm, monospermic, with coloration ranging from yellow to dark purple. The seeds measure 2.95–10.7 × 2,.5–10.5 mm, are light brown, and possess an eugenioid embryo. Germination in E. velutifolia is hypogeal, starting approximately 30 days after sowing. The average germination time is 37 days, the germination success rate was 50.42%, and the germination speed index was 1.97, with variation among parent trees. Seedlings develop over a period of 75 days, which is unusual compared to other species of the genus that exhibit faster development. The endemism and anthropogenic pressure highlight the need for proper management, including propagations protocols, as well as the development of future actions for ex situ conservation to ensure the species' survival.

The exponential increase in data volume and the dynamic nature of computer networks have imposed significant challenges on information security. In this context, classification in Continuous Data Streams (CDS) becomes essential, especially for Network Security Systems (NSS). These applications require techniques that handle memory constraints, processing time, and non-stationary data. This work proposes an adaptation of the Growing Self-Organizing Map (GSOM) for classifying firewall logs in CDS. The GSOM architecture was considered suitable, as it adjusts neuron weights to follow the gradual evolution of patterns and expands its structure to represent new behaviors as they emerge. For evaluation, real data from an operational firewall was used, classified into the actions “Allow”, “Deny”, “Reset-Both”, or “Drop”. The experiments followed an approach with offline (initial training) and online phases, where three update strategies were proposed: (1) nearest winner neuron location, keeping the map fixed; (2) dynamic map expansion, adding new neurons to represent emerging patterns; and (3) refinement of existing neuron weights, adjusting the map without altering its structure. The performance of the GSOM was evaluated in four temporal scenarios, including a combined scenario, and compared with established methods such as Incremental SVM and Adaptive Random Forest (ARF). The comparison established an upper bound of performance for the ideal scenario of zerolabel latency. Although ARF demonstrated overall superiority, its high computational cost and dependence on immediate labeling limit its practical application. It is concluded that GSOM is a viable solution for real-world classification in CDS with infinite label latency, where complete supervision is operationally unfeasible.

The increasing use of low-density polyethylene (LDPE) mulching films in agriculture has contributed to rising microplastic contamination in soils, raising concerns about their ecotoxicological effects and their interactions with pesticides. In this study, we investigated four LDPE films with different formulations and degradation levels and found that UV-C photodegradation altered their structural and chemical properties in distinct ways, thereby modifying their sorption capacity. Notably, the degraded silver film showed the highest removal of the fungicide tebuconazole from solution and proved to be the most susceptible to degradation under the conditions tested. In addition, we observed that the incorporation of pristine and degraded microplastics into the soil influenced the early development of cherry tomato (Solanum lycopersicum L.), promoting significant changes in biomass allocation patterns (SLA, SMF, RSR, and LMR), although total growth parameters were not consistently affected. Our findings indicate that, beyond polymer type, formulation and degradation level are key factors governing microplastic–plant interactions. By integrating degradation dynamics, sorption processes, and biological effects, this study advances the understanding of the complexity of these interactions in the environment and highlights the importance of considering chemical diversity and plastic aging in ecotoxicological assessments and environmental modeling.

The growing demand for sustainable, low-environmental-impact surfactants has driven the development of biotechnological routes capable of converting renewable feedstocks into high-value products. In this context, the enzymatic synthesis of xylose fatty acid esters stands out as a promising alternative, particularly due to its potential do valorize the C5 fraction of lignocellulosic biomass, which remains underexploited in industrial applications. However, challenges related to low solubility of xylose, the limited stability of biocatalysts, and reduced catalytic efficiency in non-conventional media still hinder the implementation of these processes. This thesis aimed to develop and evaluate integrated strategies for the enzymatic production of xylose esters, addressing key gaps in biocatalyst engineering, reaction medium selection, and the use of biomass-derived feedstocks. Initially, the state of the art in the enzymatic synthesis of xylose esters was assessed through systematic literature mapping, enabling the identification of recurring strategies, limitations, and opportunities related to catalysts, acyl group donors, solvents, and downstream processing. The results indicated that lipases are the preferred biocatalysts for xylose ester synthesis. Additionally, solvent selection was identified as a crucial factor, with oleic acid, lauric acid, and methyl and vinyl esters being the most commonly employed acyl donors. Subsequently, post-treatment strategies were investigated for the commercial biocatalyst Novozym® 435. The results demonstrated that coating with polyethyleneimine followed by crosslinking with glutaraldehyde yielded more robust biocatalysts, resulting in a 2.3-fold increase in oleic acid conversion when a deep eutectic solvent was used to solubilize xylose, and a 1.5-fold increase when methyl ethyl ketone and tert-butanol were employed. In addition, post-treatment improved operational stability over successive reaction cycles, with approximately 75% retention of catalytic activity after five reuse cycles. A key advancement of this work was the use of a chloride–xylose deep eutectic solvent, which significantly enhanced xylose solubility, reaching concentrations above 600 mM, substantially higher than those observed in conventional organic solvents (7 mM in methyl ethyl ketone and 60 mM in tert-butanol). This increased solubility directly improved enzymatic performance, enabling higher conversion rates and high selectivity toward xylose monoesters. In parallel, the effects of different immobilization protocols and metal modification of the lipase Eversa® Transform 2.0 were evaluated, revealing variations in catalytic activity, thermal stability, and specificity. Spectroscopic analyses confirmed conformational changes in the immobilized enzymes, allowing correlation between immobilization pH and the observed hydrolytic activity and catalytic specificity. Finally, the feasibility of producing xylose esters from sugarcane bagasse was demonstrated through the integration of biomass pretreatment and enzymatic conversion steps. Pretreatment with acetic acid and hydrogen peroxide resulted in a fourfold increase in sugar release during enzymatic hydrolysis with xylanases, compared to untreated bagasse. Biocatalysts prepared by immobilizing Eversa® Transform 2.0 at pH 5 in the presence of 100 mM NaCl, followed by metal modification with MgCl₂, were evaluated. The non-metal-modified biocatalyst exhibited superior performance, achieving 15% oleic acid conversion and 63% xylose conversion. Overall, the modulation of biocatalyst properties through immobilization and post-treatment strategies, the use of deep eutectic solvents in xylose esterification, and the application of xylose derived from sugarcane bagasse significantly advance the field of applied biocatalysis for sugar ester synthesis. This findings provide concrete perspectives for the development of sustainable industrial routes for biosurfactant production.

This dissertation analyzes the prison-based social assistance work of the Universal Church of the Kingdom of God (IURD) through its social outreach group “Universal in Prisons” (UNP), active in the Campinas region and surrounding areas. Based on an ethnography conducted among the group’s volunteers, combining participant observation and interviews, it seeks to understand the functioning of UNP through its social practices and the meanings attributed by the participants themselves. Although the literature on the IURD’s social engagement tends to emphasize the theology of spiritual warfare and institutional discourses as key explanatory frameworks, this research prioritizes the volunteers’ perspectives on their own activities, highlighting that the group is composed of individuals who have experienced incarceration, either directly or through the experience of family members and close acquaintances. The findings show that the experience of imprisonment is not limited to a biographical fact, but constitutes a fundamental element in the production of meanings that guide action within UNP, shaping volunteers’ religious and social engagement.

The study proposes a taxonomy intended to guide the analysis of instructional visual artefacts for science education, in a context in which sharing, creating, and editing images have become more common, while the distance grows between tool use and an understanding of the processes that underpin graphic and interpretive choices. The scope privileges artefacts produced with communicative intent, connected to science teaching and science communication, and assumes that strengthening repertoires for visual reading and visual production becomes necessary as the means of creation, editing, and circulation grow more complex. To support a unified analytical language, the work brings together contributions from diverse fields that make it possible to describe how artefacts organize information, structure relationships, and guide interpretive paths. It integrates studies from the psychology of perception and art theory, which emphasize perception as an organizing principle and offer categories for describing thought through form. It also draws on cartography and data visualization, with proposals for systematizing visual variables and modes of graphic construction, alongside criteria of visual economy and graphic integrity derived from statistics applied to communication. Approaches that treat the image as a contested field are also included, discussing the polysemy of the term “image,” media hybridity, and institutional tensions surrounding these concepts. Completing this set are perspectives from semiotics and visual rhetoric, which describe operations between the plastic and iconic layers of the sign; contributions on persuasive language in applied contexts that distinguish formal patterns and semantic deviations in terms of cognitive costs; and a socio-semiotic grammar focused on compositional choices, credibility, and ideological effects. In addition, the study considers models oriented toward structural unification and visualization design, including empirical dimensions for characterizing graphical abstracts, recursive descriptions of the syntax of the graphic object, and a philosophical roadmap for understanding how models can say something about the world. The Peircean framework contributes universal categories—Firstness, Secondness, and Thirdness—along with the triadic definition of the sign and its organization into classes, and it supports the connection to science education through hypoicons and their sublevels—image, diagram, and metaphor—highlighting the role of the diagram in reasoning and in making relationships explicit, as well as the importance of collateral knowledge for images and metaphors to function as interpretable statements. On this basis, concepts are selected to create a basic taxonomy as an analytical instrument aimed at reading and producing visual artefacts used in science education, organized into the following taxons: Diagrammatic Space, Diagrammatic Multiplicity, Diagrammatic Relation, Diagrammatic Composition, Diagrammatic Navigation, Temporal–Diagrammatic Stability, Diagram Interactivity, Access to the Object, and Type–Specimen. Finally, taxonomy is applied to a range of objects through detailed analyses in order to observe the behavior of the taxons, discuss results, identify strengths and weaknesses, and reflect on criteria for evaluating the procedure.

The teaching of chemistry, characterized by a high degree of conceptual abstraction, underscores the need to renew educational processes to move beyond traditional methodologies that do little to foster student autonomy and scientific as well as sociocultural development. In this context, this study examines the contributions of an interdisciplinary learning pathway (learning sequence) that integrates theater and experimental activities in inorganic chemistry to the development of scientific literacy among high school students in a public school in the state of Amapá, Brazil. Qualitative in nature, the research involved 45 third-year high school students and six teachers from different subject areas. Data were generated through questionnaires and narratives (audio recordings, videos, theatrical scripts, and learning journals), which were organized and analyzed with the support of ATLAS.ti and IRAMUTEQ software. Initial results revealed limited prior knowledge regarding the interplay between art and science and inorganic functions, low argumentative quality, and difficulty relating acids, bases, salts, and oxides to everyday life. They also indicated an ambivalent stance toward theater, marked by curiosity but also by shyness, insecurity, and a perception of elitism. Over the course of the learning pathway “Science & Art Laboratory – The Expressive Body,” most participants maintained a moderate to high level of interest in the proposal, with no decline in engagement. The narratives pointed to a reframing of theater as a learning tool, increased collaborative participation, and advances in the quality of arguments, which evolved from predominantly descriptive statements to more complex explanations that combined experimental data, concepts related to inorganic chemistry, and socioscientific contexts. The integration of art and science supported the contextualization of content, the problematization of health and environmental issues (such as gastritis and water quality), and the development of procedural, attitudinal, and critical competencies, in alignment with the scientific literacy indicators proposed by Sasseron. From a theoretical standpoint, the study brings together Driver and Newton’s hierarchical model of levels of argumentation and Sasseron’s scientific literacy indicators, offering an integrated analytical framework for understanding the development of more elaborate arguments in interdisciplinary, art-mediated proposals. In practical terms, the study systematizes a didactic intervention that can be adapted by chemistry teachers in other contexts, detailing a learning pathway (learning sequence) that connects the construction of scripts, characters, and scenes with discussions on inorganic functions and socioscientific issues. In doing so, it expands the possibilities for a context-sensitive and collaborative approach to curricular content. Socially, the research highlights the potential of science theater, understood here as a drama-based approach to science education, to promote scientific literacy in a public, socioeconomically disadvantaged context in Amapá, valuing local knowledge, life experiences, and territorial identities, while at the same time broadening students’ opportunities to engage with scientific culture. The study concludes that an interdisciplinary learning pathway (learning sequence) involving science theater as a drama-based approach to science education represents a promising strategy for reframing the discipline of chemistry, transforming initial patterns of disinterest, insecurity, and conceptual gaps into higher levels of engagement, argumentation, and contextually grounded understanding of inorganic chemistry content.

The production of seedlings of native forest species is essential to meet the increasing demand for ecological restoration and biodiversity conservation. In this context, vegetative propagation techniques have been widely investigated as an alternative to seed-based propagation, especially for species that exhibit germination limitations. Among the species of interest, Trema micranthum (L.) Blume stands out as a fast-growing pioneer species, characterized by a low germination rate from seeds, around 35%. In addition, the species shows potential for medicinal use, associated with the presence of compounds such as cannabidiol without THC in its flowers and fruits, which broadens its scientific and economic relevance. The objective of this study was to evaluate the productive performance and rooting of mini-cuttings of Trema micranthum in a clonal mini-garden system, considering the influence of climatic factors, types of mini-cuttings, spacing between ministumps, and seedling quality indicators over time. The study was conducted at the Federal University of São Carlos, Sorocaba campus, between 2023 and 2025, in a semi-hydroponic system under controlled fertigation, with two spacing arrangements between ministumps (0.10 × 0.10 m and 0.10 × 0.20 m) and successive collections of mini-cuttings. Linear and multiple regression analyses with climatic variables, Spearman correlation, time series models (ARIMA/ARIMAX), and non-parametric tests were applied to compare treatments. The results indicate temporal variation in productivity associated with the age of ministumps and temperature, while rooting did not decrease with ministump age. No statistically significant differences were observed between spacings in terms of productivity and rooting of mini-cuttings. It was observed that the average productivity was 4.1 mini-cuttings per ministump per month in the wider spacing and 3.2 mini-cuttings per ministump per month in the 0.10 × 0.10 m spacing, with rooting percentages exceeding 50% in all collections performed. Variability among ministumps in terms of average mini-cutting productivity was also verified, allowing the identification of superior and inferior individuals. It is concluded that proper management of the clonal mini-garden and the selection of productive individuals are efficient strategies to optimize the clonal production of T. micranthum, expanding its use in forest restoration and future applications of economic interest.

The Brazilian Pantanal comprises a biome responsible for an enormous diversity of fauna and flora. However, wildfires affecting this biome have become a major problem in recent years, generating impacts that may become irreversible in the future. Therefore, fire prediction methods prove to be essential and extremely important for the prevention and control of wildfires throughout this territory. Nevertheless, the main fire risk indices currently in use present limitations, such as: (1) not being adapted to the characteristics of each biome; (2) being restricted to specific climatic variables; and (3) not being able to predict forest fire risk over a defined multi-day horizon. This last aspect, in particular, is of utmost importance, as its improvement enables planning and coordinated action by environmental authorities with adequate advance notice. In order to investigate this limitation, this study developed a comparative approach between two computational models based on Machine Learning (XGBoost and LSTM), evaluating which one produced results closer to the observed reality. The results obtained indicated that the XGBoost model showed superior performance in predicting fire occurrences, achieving lower values of mean absolute error (MAE) and root mean square error (RMSE), in addition to a greater ability to explain the variability observed in the time series. The LSTM model, in turn, demonstrated the ability to capture seasonality and the average behavior of the series; however, it showed limitations in reproducing the magnitude of extreme events, especially due to univariate modeling and the effective volume of data available for training. Overall, the findings highlight that approaches based on boosting techniques combined with temporal feature engineering were more suitable for the analyzed dataset, although both methodologies confirmed the existence of learnable temporal patterns in the historical series of the Brazilian Pantanal.

The admission of students with disabilities to Higher Education has been a recurring topic in academic research, and over the last thirty years, discussions have followed the political, social, and economic changes surrounding this issue. Understanding access to Higher Education as a fundamental right, this study investigated the inclusion and accessibility actions developed within student assistance centers and divisions. From this perspective, the general objective of the research was to analyze the inclusion and accessibility actions implemented across the campuses of a federal university in Northern Brazil and to identify the challenges faced in this process. The specific objectives were: (a) to characterize accessibility centers based on the Incluir Program; (b) to analyze the distribution and organization of campuses that have Accessibility Centers and Student Assistance Divisions within a federal institution in the state of Pará; (c) to critically analyze the inclusion actions developed by a federal institution located in the state of Pará, in Northern Brazil; and (d) to demonstrate how federal institutions located in the Amazonian region of Northern Brazil have been organizing services for students who are part of the target population of Special Education on their campuses. The study adopted a qualitative approach, and data analysis was grounded in the theoretical framework of historical-dialectical materialism. The main theoretical references were Karl Marx, István Mészáros, and Valdemar Sguissardi, whose works contributed to understanding the structural contradictions of Higher Education within contemporary capitalism and supported the definition of thematic axes for analysis. The participants included nine coordinators of accessibility centers and student assistance divisions, as well as one student. The research was conducted across the campuses of the Federal University of Pará. Data were collected through semi-structured interviews conducted both online, via Google Meet, and in person. The findings reveal that, although initiatives aimed at supporting students with disabilities exist, these actions are still implemented in a fragmented manner, relying heavily on individual efforts and marked by structural weaknesses, such as the lack of adequate physical spaces, insufficient multidisciplinary teams, budgetary limitations, and the persistence of attitudinal barriers. It was observed that the multicampus expansion process, historically linked to regional economic demands, did not structurally incorporate accessibility as a transversal principle of institutional planning. It is concluded that Higher Education in Northern Brazil remains a field of political and pedagogical dispute, requiring the institutional strengthening of Accessibility Centers, the consolidation of integrated policies, and the incorporation of accessibility as a constitutive dimension of the university project. It is argued that the Amazonian public university, beyond merely complying with legal requirements, must assume a historical commitment to the democratization of knowledge and to the emancipation of historically excluded groups.

The teaching of Philosophy in Brazilian basic education is characterized by a historical trajectory marked by discontinuities and political disputes concerning curriculum and human formation. In the contemporary context, the implementation of the National Common Curricular Base (BNCC) and the reform of upper secondary education established by Law No. 13.415/2017 has reshaped curricular organization through the centrality of competencies and skills, producing direct impacts on the permanence and epistemological specificity of Philosophy teaching. Within this scenario, this dissertation aims to critically analyze the teaching of Philosophy in the Minas Gerais Reference Curriculum, investigating to what extent this document contributes to the implementation of a systematic and historically grounded philosophical education, or whether it reinforces an instrumental and adaptive conception of schooling. This is a qualitative study of a theoretical-documentary nature, grounded in historical-dialectical materialism as the methodological approach and in Historical-Critical Pedagogy as the theoretical framework. The analyzed sources include the BNCC, relevant educational legislation, and the Minas Gerais Reference Curriculum, as well as specialized literature on curriculum, Philosophy teaching, and contemporary educational policies. The results indicate that, although the Minas Gerais curriculum employs discourses related to integral education and critical thinking, its structure is strongly subordinated to the competency-based approach, which tends to fragment philosophical content and dilute the epistemological specificity of Philosophy. It is concluded that the Minas Gerais Reference Curriculum presents significant limits to the realization of Philosophy teaching consistent with the principles of Historical-Critical Pedagogy, requiring from teachers mediating and resistant practices to ensure the centrality of philosophical knowledge and omnilateral human formation. In accordance with the professional nature of the Professional Master’s Degree in Philosophy (Prof-Filo), this research articulates theoretical analysis with the development and implementation of a pedagogical intervention proposal carried out within the context of Basic Education classrooms, aimed at the systematic organization of philosophy teaching through teacher mediation and the centrality of classical philosophical contents. Such intervention seeks to challenge the limits imposed by competency-based logic, highlighting concrete possibilities for the realization of teaching oriented toward critical formation and the appropriation of historically produced philosophical knowledge.
