The assessment of empathy, an important social skill, often relies on self-report tests, which are vulnerable to social desirability (SD). This bias, characterized by individuals' tendency to respond in socially acceptable ways, can distort responses and compromise the accuracy of results, especially in empathy measures. This study examined the impact of SD on the assessment of empathy using the Online Empathy Questionnaire (QoE) and tested a new scale format (QoE-2B), focused on the frequency of empathic behaviors, aiming to minimize this bias. Participants included 1,005 individuals, who responded to versions of the traditional Likert scale (QoE-2A) or the newly proposed scale (QoE-2B), as well as the Marlowe-Crowne Social Desirability Scale (EDSMC-20) and the Big Five Inventory 2 (BFI-2-S). The results indicated that the QoE-2A showed a positive and significant correlation with the DS (r=0.35, p<0.01), while the QoE-2B showed no significant correlation with the DS (r=−0.01). Regarding personality traits, the QoE-2A correlated as expected with the BFI (e.g., Agreeableness, r=0.67), while the QoE-2B showed no significant correlation with any of the BFI dimensions. We conclude that the new scale format (QoE-2B) is promising in mitigating social desirability bias, offering a potentially more reliable assessment of empathy and raising questions about the different aspects that each format can measure.

This thesis addresses the issue of waste electrical and electronic equipment (WEEE), an environmental challenge and an opportunity for urban mining. Globally, 62 million tons were generated in 2022, with only 22.3% recycled, despite containing an estimated value of US$91 billion in metals such as Au, Ag, Cu, and Sn. Given this scenario, the objective of this thesis was to develop and propose a sustainable approach for the chemical characterization and selective recovery of these metals from printed circuit boards (PCBs). The characterization methodology prioritized direct analytical methods to minimize sample preparation and the risk of contamination. Laser-induced breakdown spectroscopy (LIBS) and energy-dispersive X-ray fluorescence (ED-XRF) techniques were used, with complex spectral data being processed by chemometric tools and computational routines developed for this purpose. Principal Component Analysis (PCA) was fundamental for exploratory analysis and for generating hyperspectral images, which allowed the spatial distribution of elements in the samples to be visualized. In addition, strategies for merging LIBS and ED-XRF data with regression models such as MLPCR and ECPR were explored to improve quantification. For metal recovery, a hydrometallurgical route was developed, a more sustainable alternative to traditional pyrometallurgical processes because it operates at temperatures below 100 °C and avoids the formation of hazardous by-products such as dioxins and furans. The method consisted of a sequential leaching process, whose most efficient and environmentally friendly sequence was: i) Cu leaching with HNO3; ii) Sn extraction with HCl; and iii) co-extraction of Ag and Au with an I2/KI solution. The main innovation was the application of LIBS combined with hyperspectral imaging as a real-time process control tool. This approach allowed the efficiency of each leaching step to be monitored quickly, economically, and with spatial resolution. Spatial analysis confirmed the uniformity of extraction, overcoming the limitation of conventional methods that only provide average concentrations. The results, validated by the ICP OES reference technique, confirmed the effectiveness of the process, with recovery rates of 100% for Cu and Ag, 97% for Sn, and 86% for Au. This thesis, therefore, validates a viable technological route for urban mining, promoting the circular economy and offering a sustainable solution for the recovery of electronic waste, with potential application on an industrial scale.

This paper aims to reflect on virginity as a topic relevant to gender discussions. To this end, we have narrowed the theme down to discourses produced in “Os Bridgertons” (2013-2016), a collection of eight historical romance novels set in the British regency period, and fan fiction derived from this canonical material. Theoretically affiliated with the theoretical-methodological device of materialist Discourse Analysis (DA), we mobilize the concepts of discursive subject, interdiscourse and intradiscourse, conditions of production, discursive formation, paraphrase, and polysemy. The corpus of analysis covers twelve excerpts in total, six from “Os Bridgertons” (2013-2016) collection and six from fanfiction in English and Portuguese available in digital form on multifandom websites. With this, we aim to investigate the tension between stabilization and displacement, in the books of the collection and in the fanfictions derived from them, of effects of meaning on female virginity sustained by different conditions of production. The theoretical-methodological device of Discourse Analysis enabled us to arrive at the reading that, in the aforementioned corpus, there is a predominance of paraphrastic processes, that is, of stabilization, with regard to the theme of female virginity, as well as the virgin woman and her first sexual intercourse.

In this study, gamification is conceptualized as a strategy for facilitating the acquisition of knowledge in Geography. The research aims to examine how, in classroom settings, the use of gamification as an instructional tool can foster students’ interest and engagement, supporting active and guided knowledge construction that integrates both theoretical content and practical application. The central research question guiding this study is: how can gamification stimulate interest and engagement among 12th-grade students in a Geography lesson on Morphoclimatic Domains? A qualitative methodology was adopted, focusing on the analysis of complex educational phenomena within their natural contexts, with particular attention to the construction and interpretation of data. The phenomenon under investigation concerns the ways in which students’ interest and engagement emerge in the classroom and how these dimensions can be enhanced through intentional pedagogical practices such as gamification. As part of a Professional Master’s program in Education, this dissertation involved the development of an Educational Product in the form of a game titled Dom – Morphoclimatic Domains, designed as a classroom instructional tool to address the study’s central research question. A questionnaire, created via Google Forms, was administered to assess students’ interest and engagement during the lesson in which the game was implemented. The study was conducted in a public school located on the coast of São Paulo state, Brazil. The findings indicate that gamification functioned effectively as an instructional tool, promoting students’ interest and engagement in the construction of geographic knowledge, while underscoring the importance of careful planning and intentional implementation. Despite challenges related to internet access on school-provided devices, students demonstrated motivation and willingness to participate in the activity. It is therefore concluded that gamification can serve as an effective instructional strategy for enhancing the interest and engagement of 12th-grade students, contributing to the meaningful construction of geographic knowledge, particularly in the context of Morphoclimatic Domains.

The general aim of this thesis is to investigate, in light of the Functional Discourse Grammar (FDG) (Hengeveld; Mackenzie, 2008) and studies by Keizer (2016, 2018), the semantic-cognitive status of idiomatic expressions (IEs) in Portuguese, using, as guiding principles, motivation, for a cognitive analysis, and compositionality, for a morphosyntactic analysis, in order to define degrees of transparency and opacity of IEs, with the purpose of proposing a typology of IEs for Portuguese. To achieve this aim, based on Keizer (2016, 2018), a set of fourteen morphosyntactic variation criteria is applied, namely: lexical substitution, adjectival modification, quantification, number, definiteness, passivization, nominalization, anaphoric reference, cataphoric reference, insertion of adverbs, insertion of pronouns, inversion of the preferred order, elision of a fixed term and possibility of conversion to imperative mode. From an initial compilation of IEs already included in dictionaries (Riva, 2009; Silva, 1997; Almeida, 2022), data collection took place, which took into account the Reference Corpus of Contemporary Portuguese (2016), written records from the web and constructed data. In view of this universe of research, the specific aims sought are: (i) to verify how the speaker's extra cognitive effort process functions, involved in the reanalysis of IEs; (ii) to check the IEs according to the alignment among the Interpersonal, Representational and Morphosyntactic levels of the FDG; and (iii) to determine how the violation of the one-to-one relationship between form and meaning of the constituent elements of the IEs occurs (Leufkens, 2015). After applying the criteria, performing the cognitive and morphosyntactic analysis of the occurrences, verifying their degree of transparency and the alignment among the levels of the model, it was possible to identify, in Portuguese, in addition to the four types of IEs found in English by Keizer (2016), a new typology, comprising the following set: (i) unmotivated and non-decomposable; (ii) motivated and non-decomposable; (iii) motivated and decomposable; (iv) AD-HOC expressions, with specific use; and the last type, (v) partially motivated by conceptual metaphors and decomposable ones. In addition to identifying this fifth type of IE in Portuguese, this research also adds to Keizer's (2016) discussion of cases of AD-HOC IEs, involving discontinuity and context dependence, and attests to the applicability of the set of primitives CombPIF – Combination of partially instantiated frames (Keizer, 2016), now with results in IEs of Lusophone varieties of Portuguese, which can contribute to expanding research horizons on the metaphorical interpretation of IEs in light of the FDG.
Das extremidades da condição humana à moral existencialista: ambiguidade em Simone de Beauvoir (1944-1947)

Au sens philosophique, la morale existentialiste de Simone de Beauvoir part du fait que les libertés sont séparées les unes des autres pour évoquer la possibilité de les concilier à partir des aspects ambigus de l’existence humaine; et, au sens littéraire, cette morale acquiert de la force à mesure que sont exposées les situations vécues par l’ensemble des personnages des romans de Beauvoir et la difficulté d’assumer ces aspects en même temps. Dans la relation entre ces deux sens, afin de mieux comprendre ce que Beauvoir appelle la « période morale » de sa carrière littéraire – période qui commence dans la décennie la plus prolifique de l’auteure sur le plan intellectuel, à savoir les années 1940, après le début de la Seconde Guerre mondiale, au moment même où sa philosophie conçoit une conjuration strictement éthico-politique face à cette crise historique –, l’objectif est d'aborder ce que Beauvoir présente comme les ambiguïtés de cette condition, c'est-à-dire en quoi consiste le drame de l’existence qui, dans son individualité, se situe avec l’autre. Il convient donc de souligner que, conformément à la circonscription proposée, nous analyserons la manière dont Beauvoir revendique les termes liberté et facticité, définis dans sa ligne de pensée respective – l’existentialisme – et constitutifs de ces relations ambiguës, afin d'étudier pourquoi les conditions humaines, bien que contingentes au départ, peuvent être réalisées et dépassées concrètement par la liberté elle-même, leur conférant un sens justifiable: c'est ce mouvement qui les fonde comme authentiques, c'est alors que leur ambiguïté fondamentale est assumée, selon Beauvoir. Il s'agit donc d’une introduction à l’intérêt de la philosophe pour la question morale et à sa relation avec les extrêmes constitutifs de ces conditions, afin de démontrer l’itinéraire par lequel ils intègrent chaque situation vécue, qui se situe entre la liberté, en tant que para-rien, et la facticité, car la liberté est ancrée dans l’être, dans son pays, son sexe, son âge, son époque, sa famille, son éducation, son économie, etc. – la donnée à transcender. À partir de là, on comprend lambiguïté comme méthode de la morale existentialiste de Beauvoir elle-même – et, dans une large mesure, de toute sa philosophie.

This thesis investigates the relationship between language and identity among young Japanese-Brazilians who grew up in transit between Japan and Brazil, experiencing multilingual contexts throughout their childhood and adolescence. In this sense, the general objective of the research is to analyze, based on the narratives of the collaborators, how the experience with plurilingual linguistic practices influenced their life trajectories and the construction of their identities. In order to achieve this objective, the research is based on the following guiding questions: (1) how were the linguistic environment and (self)recognition in the two languages (Portuguese/Japanese) configured by the collaborators in a situation of mobility between Japan and Brazil?; (2) what relationships can be established between living in a plurilingual environment and/or mobility and the choice of academic and professional path?; (3) how do the experiences of mobility and contact with different languages relate to the identity constitution of these subjects? The theoretical basis is based on the approaches to plurilingual linguistic competence by Coste, Moore and Zarate (2009), the theory of situated learning by Lave and Wenger (1991), the conceptions of relative and variable identity proposed by Block (2007) and Norton (2013), as well as the concept of “children who cross borders” by Kawakami (2010). This is therefore a qualitative, interpretivist study which uses narrative research methodology, focusing on life history and lived experience, prioritizing understanding and the construction of meanings based on the participants' accounts. The results indicate that the collaborators had partial, complementary, unbalanced and dynamic plurilingual skills, which were manifested through strategic communicative practices in everyday life. The language experiences in Portuguese and Japanese enabled them to become aware of their own language skills, which was strongly linked to how they were perceived by others in different social contexts. This perception directly influenced the use and learning of languages, as well as decisions related to university education, career choice and the development of life projects. Therefore, the analysis shows that the subjects construct their identities in constant negotiation with the cultural and linguistic contexts in which they are inserted, demonstrating that mobility and plurilingualism play a fundamental role in the constitution of the self in the present and in the projection of the future.

Multiferroic systems have attracted increasing attention because they allow the coexis tence of properties such as ferroelectricity and magnetism in a single material. Among them, Bi5Ti3FeO15 (BFT4), a member of the four-layer Aurivillius family composed of perovskite blocks interspersed with fluorite-like layers, stands out for exhibiting multiferroicity at room temperature. Consequently, the search for structural modification strategies at the atomic level has intensified in recent years, aiming to understand and control the physical behavior of these materials. In this work, we investigate the effects of alliovalent substitution of Bi3+ by Ba2+ in the BFT4 system, focusing on understanding how local distortions and changes in the defect structure influence its electrical and ferroic properties. Samples with different atomic substitution contents (0,0%, 0,6%, 3,0%, and 4,0%) were sintered via solid-state reaction and characterized by X-ray diffraction, dilatometry, impedance spectroscopy, ferroelectric hysteresis measurements, and magnetometry. From a structural point of view, Ba2+ incorporation was shown to be viable up to approximately 4%. Crystallographic refinement revealed a preferential redistribution of barium ions between the fluorite and perovskite layers, with an increasing tendency to occupy the perovskite as the doping level increased. This behavior was associated both with the relief of the internal strain generated by the mismatch between the layers and with an increased concentration of defects in this region. As the barium content increased, a progressive symmetrization of the structure was observed, accompanied by a reduction in spontaneous polarization, partially compensated by cationic disorder, and a gradual decrease in the paraelectric-ferroelectric transition temperature. As predicted by the charge compensation mechanism, impedance spectroscopy measurements indicated a progressive increase in the concentration of oxygen vacancies, reflected in the increased ionic conductivity of the system. These defects showed a strong impact on the ferroelectric behavior, acting as domain pinning centers, as evidenced by the P–E curves and dielectric responses. Finally, the nature of the magnetic interactions, predicted by the antisymmetric exchange interaction, proved sensitive to the structural modifications induced by doping, since symmetrization favored the modulation of the magnetic properties. In summary, the results demonstrate that Ba2+ doping constitutes an effective route for engineering the ferroic properties of BFT4, through both structural distortions and controlled creation of defects, contributing to a more comprehensive understanding of the multiferroicity in this system.

Modeling unobserved heterogeneity in survival analysis traditionally relies on frailty models. However, their conventional architecture, based on continuous distributions, is often restrictive in contexts exhibiting a structural cure fraction. To address this limitation, this thesis proposes an innovative discrete frailty model based on the Hurdle Zero-Modified Generalized Poisson (HZMGP) distribution. The proposed model is distinguished by a multifaceted architecture that provides three key advantages: its discrete nature offers a natural representation of cured individuals (zero frailty); its zero-modification structure flexibly accommodates diverse patterns of zeros (inflated, deflated, or truncated); and its inclusion of a dispersion parameter captures variability arising from latent risk factors. Inference for the model was developed and validated under both frequentist and Bayesian paradigms. Extensive simulation studies in both frameworks confirmed the estimators' asymptotic properties and, crucially, demonstrated the model's flexibility to accurately capture scenarios both with and without a cure fraction. The model's utility and versatility are ultimately demonstrated through its application to two contrasting oncology datasets, validating its relevance for clinical practice. Furthermore, the Bayesian framework yielded two of the thesis's most significant contributions: a probabilistic classification rule for individual prognostic stratification, and a novel conceptual interpretation of the dispersion parameter as a statistical proxy for unobserved biological heterogeneity. These advances represent a significant contribution to the analysis of complex survival data.

The frequently collected data regarding user interaction with software (i.e., UX data) holds potential to enhance User Experience (UX), which encompasses users' emotional, practical, and perceived value interactions with products. However, a challenge exists between the collection of UX data and its effective analysis. Software practitioners frequently encounter difficulties in selecting relevant data and applying appropriate techniques to gain insights for software improvement. The field of Information Visualization (InfoVis) offers approaches to assist users in analyzing emerging information from data. While initial efforts explored how InfoVis principles could be applied, this research revealed a more fundamental problem. A Grey Literature Review on UX data not only identified diverse formats, definitions, and suggested visual representations but, exposed a pervasive lack of formal UX data definitions in practice. Two initial exploratory studies further reinforced these challenges, demonstrating that practitioners struggled to derive insights from unstructured UX data without a clear conceptual foundation. Building upon these findings, this research strategically pivoted its focus to address the core issue for effective UX data analysis. The central artifact developed is a UX data taxonomy, designed to organize and clarify UX data understanding by categorizing objectives, purposes, and data characteristics. This taxonomy itself represents a theoretical contribution, providing a structured model for the UX data domain. To ensure its practical utility and accessibility, this taxonomy was operationalized through two distinct tools: an interactive web-based system for exploration and a Generative AI (GenAI) RAG (Retrieval-Augmented Generation) chat tool for natural language interaction. The utility and acceptance of this taxonomy and its related tools were then empirically validated with software professionals. Finally, the research also explored emerging opportunities for UX data analysis, particularly concerning the role of GenAI, assessing how these advancements intersect with the need for structured data understanding, thus providing theoretical insights into the evolving landscape of UX data analysis. This thesis provides both practical tools to empower software professionals in leveraging UX data for enhancing interactive system design, and lays a theoretical foundation for understanding and working with UX data.

This research offers a critical analysis of the São Paulo State Curriculum for English Language Teaching in the Early Years of Elementary Education (CP-LIAI), understanding it not as a neutral document but as a political and discursive artifact. Based on a qualitative and interpretative approach within the field of Critical Applied Linguistics, the study examines how the skills proposed for the 4th and 5th grades articulate, or fail to articulate, linguistic, cognitive, sociocultural, and socioemotional dimensions of English language learning, in light of theories of critical literacy and multiliteracies. The analysis revealed that the CP-LIAI presents some progressive elements, such as the emphasis on orality and ludic engagement, but remains largely tied to prescriptive and technicist logic. Inclusive pedagogical intentions often coexist with formulations focused on memorization and the isolated reproduction of linguistic structures, contradicting the principles of a situated, ethical, and plural language education. The lack of child-centered listening in the construction of the curriculum further limits its transformative potential. The study also emphasizes the central role of the teacher: it is through critical reading, pedagogical mediation, and daily reinvention that the curriculum can be re-signified. However, this requires adequate working conditions and public policies that promote continuous and critical teacher education. The findings suggest the need to review and expand the CP-LIAI based on principles of social justice, inclusion, and recognition of children’s voices. The curriculum, as a space of dispute, must be reinterpreted as a site for listening, creation, and transformation. English language education in early schooling should recognize the child as an epistemic subject, a meaning-maker, and an active participant in real and meaningful discursive practices.

Semantic annotation of corpora plays a crucial role in the development of Natural Language Processing (NLP) tools. In the case of user generated content (UGC) corpora composed of tweets whose language is predominantly informal semantic annotations typically focus on lexical aspects such as named entities, emotion, or polarity. In this study, we investigated the sentential semantic representation of Portuguese language financial market tweets via the Abstract Meaning Representation (AMR) framework, under the hypothesis that syntactic information can aid such representations. To this end, we annotated the DANTEStocks corpus, the first tweebank with grammatical annotation according to the Universal Dependencies (UD) formalism, covering a subset of 1,128 of the 4,048 tweets (i.e. 30% of the total). The AMR annotation followed a hybrid methodology, comprising a manual phase to establish guidelines and reference models, and a semiautomatic phase in which manually curated corrections were applied to graphs produced by a large language model. This process confirmed our hypothesis that UD syntactic dependencies facilitate the construction of AMR graphs, particularly in identifying subgraphs and relations among concepts. Additional contributions include: (i) the development and validation of AMR annotation guidelines for phenomena specific to Portuguese, UGC, and the financial domain; (ii) the proposal of labels for three types of financial domain entities (URLs, tickers, and users); and (iii) the introduction of a frameset for the VerboBrasil repository covering the financial verb repicar. The primary challenge encountered was interpreting tweets for AMR graph construction, given their fragmentation, truncation, contextual dependence, and specialized vocabulary necessitating continuous expert consultation and external financial-domain resources. Nevertheless, even with a relatively small validation set, an inter-annotator F-score of 89% indicates that the AMR-annotated portion of DANTEStocks is a reliable resource for pioneering research on AMR parsing of tweets in NLP and for guiding the annotation of the remaining corpus.

This original study aims to analyze data from lecture-style videos produced by the "O Extensionista" YouTube channel. The aim was to understand how digital platforms are transforming teaching methodologies and communication in rural areas. In the field of STS, this research demonstrates how technologies and social practices intertwine in rural extension. Dialogical communication in ATER Digital values local knowledge and concrete experiences, while engagement data highlights the importance of formats that respect cultural plurality and rural protagonism, promoting more inclusive and collective extension practices. The guiding question of the study was to understand how videos on the "O Extensionista" YouTube channel, as an ATER Digital initiative, promote engagement and contribute to the innovation and improvement of rural extension practices in Brazil. Furthermore, we sought to answer which attributes of the channel's videos influence public participation and engagement in digital rural extension initiatives. And how do the data on views, likes, and interactions on the channel's videos reflect the effectiveness of Digital ATER initiatives? The research is configured as an exploratory and descriptive investigation. In turn, the collected data were schematized and organized for quantitative analysis. The channel "O Extensionista" has over 96,000 subscribers, has published over 6,800 videos, and has received over 34 million views. The sample for analysis comprises 75 videos generated on the channel from weekly live streams discussing topics related to digital ATER, research, and rural extension worker training. The videos in the sample under investigation have 21,967 views, 1,880 likes, and 1,893 interactions in the chat as their main metrics. The data was organized and categorized by speaker profile, gender, time period, talk/live stream duration, and language. The analyses were constructed using descriptive statistical parameters such as arithmetic mean, standard deviation and coefficient of variation. The most discussed topics were "Scenarios: Challenges and Opportunities in ATER (24%)" and "Technology and Innovation in Rural Extension (22.67%)". The topic with the highest average number of views was "Public Policies, Planning and Regulation of ATER (374)". The most common speaker profile is characterized by rural extensionists and males.

This research investigates the challenges of restructuring secondary education in the state of Amazonas, with the general aim of analyzing the tensions present in the process of implementing the policy, based on the perceptions of educators and managers from different regions of the state. In addition to the difficulties inherent to regional specificities, such as geographical distance and limited access, the research highlights the internal, ethnic and racial diversity of the Amazonian territory as an aspect that is little considered in the formulation and implementation of educational policy. The research is driven by the following question: how can we guide the implementation of a public education policy that takes territorial diversity as a reference and starting point? The thesis was built along three main lines: (1) a bibliographical survey of the latest high school reforms in Brazil; (2) the characterization and analysis of the proposal to restructure high school in the state of Amazonas; and (3) the comparison between this proposal and the perceptions of teachers and managers in the various regions of the state. Through these paths, the research seeks to contribute to reflection on educational policies that dialogue with the socio-cultural contexts in which they are implemented, recognizing diversity as a structuring element of educational provision. The methodological choices are based on post-critical studies in education, as proposed by Meyer and Paraíso (2021). Based on a qualitative approach, it combines documentary analysis with a bibliographical review, followed by dense field research, carried out in at least one municipality in each channel of the main rivers in the Amazon, through re-signified narrative interviews (Andrade, 2012) with educators who work in secondary education in the state of Amazonas.The theoretical framework that underpins the research is based on approaches that dialog with post-critical theories in education, such as cultural, decolonial and ethnic-racial studies.The data analysis was organized into five main axes: general infrastructure; pedagogical and teaching structure; teacher training; student protagonism and indigenous education.The main findings indicate that the restructuring of secondary education in Amazonas has taken on worrying contours due to the profound territorial, social and cultural inequalities that mark the interior of the Amazon region, which were not considered at the time of implementation of this important public policy.

Beef cattle production plays a pivotal role in global food systems and national economies. Digital technologies offer substantial opportunities to enhance operational management, automate processes, and optimize input use. This dissertation pursues two complementary objectives: (i) to identify the main factors associated with the adoption of digital technologies by feedlot beef cattle producers; and (ii) to examine how, and to what extent, digitalization, human capabilities, marketing capabilities, and supply chain integration are linked to the technical efficiency of Brazilian feedlots. A systematic literature review was conducted to map the global landscape of digital technology adoption in beef and dairy cattle production and to identify potential determinants. Empirically, Multiple Correspondence Analysis and Stochastic Frontier Models were applied to data collected from 238 Brazilian feedlot producers (359 observations) between 2020 and 2023. Results show that dairy producers exhibit higher adoption rates of data acquisition and communication technologies as well as automation, control, and robotics systems, whereas beef producers complement these with information system technologies. Technology adoption is associated with producer characteristics (age, education, access to consultancy) and production features (scale, labor, risk management practices, custom feeding services, and slaughterhouse bonuses). Adoption of digital management software, automated feed distribution sensors, and formal contracting is positively linked to higher technical efficiency. These findings provide empirical evidence to guide policy design and support the diffusion of digital technologies in livestock systems.

The design of complex and deep neural networks is often performed by identifying and combining building blocks and progressively selecting the most promising combination. Neuroevolution automates this process by employing evolutionary algorithms to guide the search. Within this field, grammar-based evolutionary algorithms have been demonstrated to be powerful tools to describe and thus encode complex neural architectures effectively. In this context, this research proposes a novel grammar-based multi-objective neuroevolutionary approach for generating fully convolutional networks. The proposed method, named Multi-Objective gRammatical Evolution for FUlly convolutional Networks (MOREFUN), includes a new efficient way to encode skip-connections, facilitating the description of complex search spaces and the injection of domain knowledge in the search procedure, the generation of fully convolutional networks upsampling of lower-resolution inputs in multi-input layers, the usage of multi-objective fitness, and the inclusion of data augmentation and optimizer settings in the grammar. The best networks found by the algorithm outperformed those generated by previous grammar-based evolutionary algorithms, achieving 90% accuracy on CIFAR-10 without using transfer learning, ensembles, or test-time data augmentation, while having a relatively small number of parameters.

The work presents the process of creation, organization, and analysis of the book "Letters to Mari – Poetics and Crossroads of Occupational Therapy as Life Production," organized as a formative, affective, and collective device dedicated to the trajectory and thot of Mariângela Quarentei. The research describes the construction of the book from its initial conception to the stages of invitation, receipt of texts, editing, layout, and finalization of the work, highlighting how each phase expresses the principles of Occupational Therapy as Life Production (OTLP). The study highlights the relevance of TOPV as a theoretical-methodological framework marked by singularity, creation, and the inseparability between life, practice, and human activity. Based on the analysis of the letters and artistic productions sent by invited authors, the work identifies central elements of the constitution of TOPV, its expansion into different professional territories, and the formative power of the encounters, affections, and ways of being that traverse this field. Furthermore, it highlights the tensions between this living and experimental framework and traditional academic structures, emphasizing the need to expand its presence in university training spaces. The study concludes that the book materializes a continuous gesture of memory, creation, and the production of life, reaffirming the ethical-aesthetic that sustains the practice of Occupational Therapy within this horizon and opening pathways for new investigations, practices, and shared experiences.

The excessive release of CO₂, a greenhouse gas, contributes to the rise in the planet’s average temperature, leading to significant environmental and economic impacts. Converting CO₂ into methanol through hydrogenation yielding renewable methanol, a fuel and an important feedstock in the chemical industry emerges as a promising alternative to reduce the concentration of this gas in the atmosphere. In this context, simulating both the renewable methanol production process and the main routes for obtaining the raw materials, CO₂ and H₂, provides valuable insights into the generation of this product. Therefore, this work aims to simulate in Aspen Plus version 14 the processes involved in renewable methanol formation via catalytic reaction, alkaline water electrolysis, and CO₂ absorption from greenhouse gas streams using monoethanolamine (MEA). These simulations demonstrated consistency with existing green methanol production facilities, such as those developed by the Icelandic company Carbon Recycling International (CRI), and allowed a comparison of the required amounts of CO₂ and water needed for such operations. In this way, a mass yield of 72.5% was obtained for carbon capture and a consumption of 2.25 tons of water in alkaline electrolysis per ton of methanol produced.

Burnout Syndrome is an occupational problem among teachers, related to continuous stressors that result in exhaustion. Self-care practices, such as breathing and relaxation, are effective interventions for stress prevention and reduction. Concurrently, the Programming of Conditions for Behavior Development (PCDC) is an efficient technology for teaching specific behaviors. The present study aimed to evaluate the contribution of applying a PCDC-based teaching program of relaxation and emotional self-control strategies to reduce the risks of Burnout Syndrome in teachers. Six elementary school teachers from a São Carlos State Public School participated, divided into an experimental group (n=3) and a control group (n=3). The pre-test included the Brazilian Burnout Scale (EBBurn), the WHOQOL-bref, the LIPP Stress Symptoms Inventory for Adults - Revised (ISSL-R), and a Self-Care Behaviors Questionnaire. The intervention, applied to the experimental group, was a 9-weekly session program, based on PCDC and Behavioral Skills Training (BST), covering relaxation techniques and other self-care practices. Post-test and follow-up (two months after the post-test) consisted of reapplying the same instruments. Results for the experimental group revealed significant reductions in mean Stress levels (69.9% decrease post-test and 51.8% at follow-up) and Burnout levels (23.7% decrease post-test and 22.2% at follow-up). Mean quality of life for this group increased (31% post-test and 27.5% at follow-up). The control group, in contrast, maintained stable levels across all instruments. Additionally, self-care behaviors in the experimental group showed a notable increase (86.6% post-test, with maintenance at follow-up), and the perception of positive consequences, like stress reduction, reinforced adherence. Findings support self-care studies in stress reduction and the effectiveness of PCDC-based programs for preventing and managing Burnout Syndrome in teachers.

Introduction: Occupational therapists worldwide have implemented Animal-Assisted Therapy (AAT), integrating dogs into the care of children on Autism Spectrum Disorder (ASD). Studies indicate that children on ASD have limitations in social and emotional behaviors, such as making eye contact and smiling, as well as in components of engagement, such as motivation and perseverance in carrying out activities. The lack of these skills impairs social interaction, communication, and occupational performance. Objective: To identify and describe changes in social and emotional behaviors, as well as in the components of engagement of children on ASD after participating in Canine-Assisted Occupational Therapy programs. Furthermore, it aims to describe the activities carried out with a focus on stimulating and developing these behaviors and components. Methodology: A collective case study method was used, using qualitative and quantitative document analysis before and after the intervention. The sample consisted of four boys, two three years old and two six years old, and their respective mothers. The mothers completed the Canadian Measure of Occupational Performance pre- and post-intervention, and recordings of five weekly sessions with each child were analyzed. For each session, the frequency of social and emotional behaviors and components of occupational performance and engagement were recorded on a checklist. Results: From the first session, the children demonstrated eye contact and smiles directed at the dog, which were extended to the therapist in subsequent sessions. As eye contact and smiles increased, they demonstrated increased engagement components (motivation and perseverance), despite functional performance difficulties (fine and gross motor coordination, balance, attention, problem-solving). They also demonstrated increased positive emotional and social skills, such as voluntarily touching the dog, talking to the dog, and staying closer to the dog, which also extended to the therapist. Conclusions: Based on the theory of biophilia, it is concluded that the child-dog bond in the therapeutic environment favored increased eye contact and smiling, which suggests the other changes observed in the interaction with the dog and the therapist, as well as in the components of occupational engagement. Future research is needed to validate eye contact and smiling as measures of evaluating the effectiveness of Canine-Assisted Occupational Therapy for children on ASD.
