In a business context where it is always desirable to maximize profits, the reduction of products’ manufacture cost appears as a strategic alternative, whether through optimization of oversized parts or the removal of fastening components, such as screws. The main challenge to achieve this, however, is maintaining the quality and functionality of what is being produced and sold. This scenario is currently evident for those who work in the home appliance industry in Brazil, with consumers demanding better and more affordable home appliances. In this context, this document proposes to analyze the technical feasibility of reducing the number of screws that fix the tub on the tub support of washing machines, considering the need to guarantee their quality and safety in use. This study was carried out through the development of practical experiments, product-level tests to evaluate the performance of the proposed model, and comparative tests to visualize, through statistical analysis of the results and research of pre-existing knowledge, if there has been a loss of quality. The studies have shown that the reduction is promising, contributing to cost reduction without impacting the functionality of the washing set.

This study discusses the definition of the Esports Live Stream genre and addresses aspects of accessibility features in live broadcasts of digital games, with a focus on the game League of Legends (LoL). It explores the enunciative and discursive specificities that characterize this audiovisual genre. Based on Mikhail Bakhtin's theory of speech genres and on technical accessibility standards, the analysis shows that linguistic accessibility for deaf individuals goes beyond technical issues such as capturing the interpreter's image or the use of subtitles. The study highlights the need to consider the interactive, dynamic, and multimodal particularities inherent to game livestreams, so that features like Brazilian Sign Language (Libras) windows, subtitling, and other tools can be adapted to integrate effectively with the broadcast content. To support this discussion, a live broadcast from the competitive LoL scene was analyzed, considering the accessibility features available during the live transmission and their impact on inclusion and viewer experience. The results indicate that accessibility resources were only present in three segments—advertisements, the pre-game, and the post-game—leaving out core aspects of the genre, such as sports commentary.

Brain atrophy is a progressive process typically associated with natural aging. In neurodegenerative diseases such as Alzheimer’s disease (AD), this process is accelerated, manifesting in symptoms related to memory loss, reasoning difficulties, and behavioral changes. Currently, there is no cure for AD, and early treatment remains the most effective way to mitigate or delay symptoms. In addition to clinical tests and family history, structural Magnetic Resonance Imaging (MRI) of the brain plays a fundamental role in diagnosis, as it enables visual assessment of brain atrophy—allowing comparison with age-related atrophy—and assists in ruling out other possible comorbidities from treatable dementias. Moreover, inter-hemispheric alterations are associated with AD and can be observed in MRI scans. Recent studies have investigated new methods for quantifying such asymmetries in order to develop biomarkers for supporting AD diagnosis and to train classifiers for automated diagnosis. However, despite promising results, visual inspection remains the most common approach for evaluating AD presence in MRI images. In this context, this work proposes a new methodology to quantify inter-hemispheric hippocampal asymmetries based on geometric and textural descriptors, focusing on predicting the progression from stable to progressive Mild Cognitive Impairment (MCI). The approach employs the shape context technique to extract log-spherical histograms from the accumulated energy map of the 3D Dual-Tree Complex Wavelet Transform (DT-CWT) in the hippocampal region. These descriptors, combined with volumetric features, are fed into a Convolutional Siamese neural network specifically designed to model inter-hemispheric differences. The proposed methodology achieved an F1-score of 0.845 ± 0.01 in distinguishing stable from progressive MCI cases. Additional binary classification experiments involving cognitively normal (CN), MCI, and AD subjects were also conducted, with consistent results: CN vs. AD (F1-score = 0.872 ± 0.05), CN vs. MCI (0.757 ± 0.03), and MCI vs. AD (0.731 ± 0.05). These findings demonstrate the influence of inter-hemispheric hippocampal alterations during AD progression and the effectiveness of these features for disease prediction and prognosis.

The machining of hard and brittle materials, such as ceramics and crystalline materials like quartz, is widely used in the construction of piezoelectric sensors and microelectromechanical systems (MEMS). The need to machine these materials efficiently and economically has become critical as the demand for affordable piezoelectric devices has increased, intensifying research in the area. Therefore, this work evaluated the performance of an experimental equipment, called C3L, with a tilting spindle for machining channels with an abrasive disk in polycrystalline alumina with 99.8% purity and monocrystalline α-quartz (AT plane) with the objective of verifying the ability of the C3L equipment to achieve results comparable to the commercial machine DISCO HI TECH DAD 3350. The C3L machine has a table with movement in Cartesian coordinates X, Y and Z and a bearing-mounted tilting spindle, capable of operating between horizontal and vertical positions. For this work, the project and construction of a flange for fixing the abrasive disk were developed. The equipment used as a reference for machining validation was a DISCO DAD3350 cutting machine, operating with an aerostatic spindle. The methodology for verifying failures consisted of dimensional analysis of chipping by optical microscopy, following a protocol already established in the literature that presents the average dimension of the chips caused by abrasive cutting as machining quality. The first material machined was a block of polycrystalline alumina (Al2O3), with 99.8% purity, measuring 34 × 34 × 8.5 mm. The part was ground to eliminate imperfections and the tests were carried out using an abrasive cutting disk model THERMOCARBON 2.25M-10C-54R7-3, which has an external diameter of 57.15 mm, thickness of 0.254 ± 0.010 mm, grain size of approximately 54 µm, and cooling was performed with water, applied manually. For alumina, with the same parameters applied in the commercial machine, the C3L showed average chipping of 15.69 µm against 20.50 µm of the DAD3350, representing an improvement of 23.5% in surface quality. However, angular misalignment was found between the spindle and the table, around Z, resulting in channel width 1.5 to 2.3 times the nominal thickness of the disk (254 µm). After aligning the table with a dial indicator, tests were carried out with quartz, which evaluated rotations (5,000; 10,000 and 15,000 rpm), feeds (0.1; 1 and 5 mm/s) and depths (0.1 and 0.3 mm); the smallest average flaw size (6.45 µm) occurred with a feed of 0.1 mm/s, depth of 0.3 mm and 10,000 rpm, while the largest average flaw size was identified in the cut with a feed of 5 mm/s, depth of 0.1 mm and 10,000 rpm, resulting in an average flaw size of 20.89 µm. Analysis of the tool after cutting revealed an asymmetric wear pattern on the disk, evidencing the misalignment, around Y, in the positioning of the spindle. It is concluded that, despite the need to correct the misalignment and implement automated cooling to optimize the process, the results demonstrate the technical feasibility of the C3L machine for machining α-quartz, with performance comparable to commercial equipment.

Despite being well-established industrially, ethanol fermentation is limited by the toxic effect of ethanol on yeast, resulting in wines with low alcohol content (10–15% v/v). Ethanol removal techniques can be applied to mitigate the inhibitory effect of the product and increase process productivity. In this context, the present work evaluated extractive ethanol fermentation using vacuum-assisted gas stripping. Initially, ethanol removal from hydroalcoholic solutions was investigated under different operational configurations of CO₂ specific flow rate, temperature, and pressure, with the aim of identifying the conditions that provided the highest ethanol removal from the liquid phase and the highest concentration in the gas phase. Subsequently, extractive fermentations with saccharine feedstock were assessed using both conventional and vacuum-assisted gas stripping, and the energy requirements of both processes were analyzed. Finally, extractive fermentations with starchy feedstock were conducted in separate hydrolysis and fermentation (SHF) and simultaneous saccharification and fermentation (SSF) processes. Mathematical models were developed to describe the processes, based on mass balance equations and incorporating the kinetics of hydrolysis, fermentation, and ethanol and water removal. The results of ethanol removal from hydroalcoholic solutions showed that all three operational variables significantly affected the process within the evaluated experimental range. The application of the technique increased the ethanol concentration in the gas phase by up to six times. In extractive fermentations with saccharine feedstock, both vacuum-assisted and conventional gas stripping increased ethanol productivity by up to 14.3%. The energy analysis indicated that the integrated technique reduced energy demand by 31.3% compared to conventional gas stripping. Finally, extractive fermentation of starchy feedstock increased ethanol productivity by 60% compared to conventional fermentation. The mathematical model adequately described the fermentation process. Vacuum-assisted gas stripping demonstrated potential as a promising technique, with the capacity to enhance ethanol productivity and lower the costs associated with the recovery and concentration of the removed ethanol.

Este trabajo de fin de máster tiene como objetivo analizar algunos cuentos de Horacio Quiroga por la óptica de la crítica sociológica. Dichos textos están ambientados en las regiones a las que el Estado liberal argentino del siglo diecinueve nombró Desierto. Aunque fuera considerado inculto y bárbaro por los autonombrados civilizadores, este espacio se muestra en la literatura del rioplatense como lugar de resistencia, lleno de cuerpos y conciencias que la Nación moderna quiso afuera del ideal de “civilización” planteado. Desde este borde, la escritura quiroguiana reverbera los conflictos del hombre ante la naturaleza, la historia y el propio hombre, convirtiéndolos en literatura. Para ello, tomaré como aporte teórico-metodológico el concepto de Heterogeneidad sociocultural, propuesto por Cornejo Polar (2003), a partir del análisis de los núcleos problemáticos que el autor establece como centrales para la comprensión de literaturas que se producen en contextos donde coexisten dos o más universos socioculturales. La ida de Horacio Quiroga al Desierto no trata simplemente de sus años como habitante en el norte argentino, sino de la consolidación de un discurso literario. El corpus de la investigación está compuesto por los cuentos “El mármol inútil” (1906), “La Insolación” (1908), “El simún” (1917), “El yaciyateré” (1917), “Los fabricantes de carbón” (1918) y “En la Noche” (1919). En dichos relatos, por medio de la confrontación entre los textos y las tensiones de ámbito sociohistóricas, buscaré demostrar cómo se constituyen el sujeto, el discurso y la representación. Además, los trabajos de Alves-Bezerra (2008) acerca de la obra de Quiroga, de Tulio Halperin Donghi (1992) sobre la constitución de la nación argentina hacia el Desierto y de Jens Andermann (2000) sobre el espacio aportan ricas contribuciones a la investigación, con las que concluí, por fin, que la literatura de Horacio Quiroga es heterogenia y es por este motivo que el autor cuestiona la historia y los discursos de la ocupación del Desierto argentino.

This study investigates how the relationship between physics and art has been addressed in the Brazilian scientific literature in the field of physics education. It is a qualitative bibliographic analysis based on articles published between 2010 and 2024 in three Brazilian physics education journals classified as A by Qualis in the 2017–2020 quadrennium. In total, 22 articles were identified as the corpus of analysis. Inspired by Bardin’s Content Analysis methodology, the study developed two categorization criteria to examine the articles: the articulation criterion, which describes how physics is related to art through five analytical categories (cultural, motivational, interdisciplinary, integrative, and contextualizing); and the function criterion, which defines the role attributed to the relationship between physics and art in the articles, with four analytical categories (critical, formative, instrumental, and epistemological). The results reveal that the formative function was the most prevalent, highlighting the potential of the relationship between physics and art to broaden worldviews and foster a more sensitive and meaningful scientific education. Although the instrumental function remains common, its isolated use tends to limit the pedagogical potential of the relationship. Cultural and integrative articulations also stand out as the most versatile and formative.

This doctoral thesis was developed in the Graduate Program in Education (PPGE) at the Federal University of São Carlos (UFSCar) in the research area of Education, Culture, and Subjectivity, and is also the result of discussions and studies by the Research Group on Compassion Science and Education. We seek to analyze the following issues: How does the National Common Core Curriculum (BNCC) incorporate this issue? How do critics of the social-emotional education present in the BNCC present their arguments? And also, how can we think about social-emotional education that goes beyond the debate generated by the BNCC? Thus, our hypothesis is that the BNCC includes social-emotional education in a restricted and superficial manner, aligned with a technical and instrumental approach. The general objective is to analyze how social-emotional education has been presented within the scope of the BNCC, in order to also highlight how its critics have constructed their arguments against it. The methodology used to develop the research problem and objectives was theoretical and bibliographic research. First, we surveyed 19 articles available on the Capes Journal Portal, published between 2018 and 2022. We selected the year 2018 because it marked the approval and beginning of the implementation of the BNCC in schools. These studies address both the historical context of its construction and implementation and the appropriation of social-emotional learning in the Brazilian context. In addition, we conducted a second data search in the Web of Science database, between 2020 and 2024, with the aim of identifying more recent research. From this selection, we obtained 23 meta-analysis articles that investigate international social-emotional learning programs and strategies, highlighting effective results for both teaching and student learning. Thus, in our analysis, we were able to understand that social-emotional learning is seen in the 19 articles as the preparation and inclusion of students for the job market and that the business environment has a significant influence on both the BNCC and the introduction of social-emotional learning in Brazil. The 23 meta-analysis studies reviewed indicate that the concept of social-emotional learning adopted in several countries is broad, contextualized, and multidimensional, contrasting with the BNCC approach, which is more restrictive, technical, and prescriptive. Furthermore, there is a lack of clear guidelines in the Base regarding the teacher training necessary for a critical and contextualized practice of social-emotional learning. Thus, ideal social-emotional learning is focused on training conscious individuals who are capable of acting on reality and contributing to the construction of a more just, humane, and supportive society.

The 1988 Federal Constitution, in articles 206 and 207, guarantees public universities full academic, scientific, administrative and financial management autonomy. The autonomous university represents one of the pillars of the Democratic State of Law, given that it allows the production and dissemination of knowledge and the pluralism of ideas. In this context, important questions arise: have the actions of the Presidents of the Republic weakened university autonomy? Do the actions of the federal government, especially between 2019 and 2022, constitute political intervention in universities? Is university autonomy consolidated at its foundations? This study aims to investigate these questions based on three main axes: (i) the analysis of university autonomy as a constitutional principle and its scope; (ii) the understanding of the relationship between university autonomy and the development of democracy; and (iii) the evaluation of the performance of the federal Executive Branch in relation to public universities, with special attention to the appointment of rectors of federal higher education institutions. With a qualitative approach, the documentary research establishes a comparison between the appointments made by the President of the Republic between the periods of 2018 to 2022 and 2010 to 2014. It specifically analyzes whether the appointments were made based on the list of three candidates sent by the universities to the Ministry of Education, comparing the presidential acts with the manifestations of the university communities. The intention is to highlight possible tensions between the acts of the Executive and the constitutional principles that guarantee university autonomy in Brazil.
Livros, discurso e política: como uma aposta dobrada no paradigma de “massas” ancorou, no Brasil, uma coesão “um pouco mais à direita”

This doctoral thesis investigates the emergence of a right-leaning cohesion that became hegemonic in Brazil around 2013, mirrored in an editorial field typified by trendsetter authors such as Olavo de Carvalho. We begin with Carvalho’s trilogy published between 1994 and 1996, as well as his activity in open courses and newspaper columns, to understand how his work exemplifies a double-down bet on the “masses” paradigm. Carvalho’s writings, we argue, would come to organize the discursive conditions that would later constitute this cohesion and the editorial segment that sustains it. In examining it, we observe that the phenomenon increasingly structures itself through books – taken not merely as vehicles of ideas but as discursive devices of validation, promoting shared meanings and “relations between people” articulated from a position slightly to the right of Brazil’s 1988 democratic framework. Our guiding hypothesis is that this field is discursively and politically structured by a double-down bet on the paradigm of the “masses,” defined, following Jesús Martín-Barbero (1987), as a belief (a) in the ineptitude of the masses, (b) in the inviability of mediations, and (c) in the permanent delegation of historical agency to allegedly superior individuals. The study is organized around three complementary dimensions: (i) an ontological analysis of the book as object—considering its unifying effects, its relation to authorship, and its market aspects; (ii) an editorial genealogy encompassing at least three generations of authors (subscribers and typifiers) of the cohesion; and (iii) a detailed analysis of the mechanisms of discursive regulation that constitute it, beginning with Carvalho’s work, interpreted here as a (pseudo)-epistemological dimension of this double-down bet (as exemplified by the cohesion). Along this path, we also consider the works of Reinaldo Azevedo and Martin Vasques da Cunha—representatives of the segment in the second and third “thirds,” respectively—as well as apologetic productions from the later period (such as those of Escorsim and Berlanza). We demonstrate that this cohesion defines itself by rejecting the common middle ground established by the representative pact of 1988, positioning itself slightly to its right and taking said double-down bet as its synthesis. The doctoral thesis thus contributes to debates on contemporary political culture and on the ways cultural objects—such as the book—operate in favor of ideological arrangements seeking legitimacy at the margins of academia.

Occupational Therapy practices in the field of physical rehabilitation in Brazil have historically been grounded in a set of profession-specific knowledge, while also being influenced by service demands, the advancement of scientific evidence, and national and international policies. The perspectives of theoretical models and practical frameworks also guide these practices, in alignment with academic production. This study aims to characterize the professional practice of occupational therapists working in adult physical rehabilitation in Brazil. It is a quantitative and qualitative study with a descriptive and exploratory design, conducted in two phases. The first phase consisted of data collection through a self-administered semi-structured questionnaire, developed by a group of researchers and made available online via Google Forms®. The second phase involved semi-structured interviews. In the first phase, the sample consisted of 109 occupational therapists with undergraduate degrees who work in adult physical rehabilitation; in the second phase, 19 professionals were interviewed. Regarding sample characteristics, 59% of participants were between 31 and 40 years old, and 64.8% had completed postgraduate specialization programs, particularly in the areas of wheelchair provision, assistive technology, and orthoses. Concerning their workplaces, 56.5% were employed in rehabilitation centers and 44.4% in clinics, with most professionals working in two or more settings. Participants reported frequent use of both standardized instruments and tools developed within their own services. The Functional Independence Measure (FIM) was reported by 56% of the sample; however, when considering all instruments cited, it accounted for 13.4% of the total. Notably, 63.5% of the instruments primarily assess body structure and function domains, according to the International Classification of Functioning, Disability and Health (ICF). Among the most frequently reported therapeutic practices were exercises, performed by 75% of respondents. Qualitative findings indicated that institutional contexts—including practice settings, management, and service dynamics—impact the work of occupational therapists. Mastery of the ICF framework was observed as a means to enhance team communication; however, there was limited appropriation of Occupational Therapy theoretical models and critical reflection on their relevance to practice. Nevertheless, the concept of occupation was identified as guiding professional reasoning. Although most professionals reported additional training in assistive technology, its practical application—such as prescription, fabrication, or adaptation—was not frequent. The study concludes that it provides relevant contributions to the field of physical rehabilitation in Occupational Therapy and supports the strengthening of public policies aimed at adult rehabilitation. Furthermore, the data collection instrument used in the first phase proved to be important in promoting professional reflection on practice within the context of functional health and physical rehabilitation.

At the beginning of century XXI, due to a traumatic event that present us a global health crisis and a far-right government that ascends the power, we observe beyond individual and collective traumas, a sequence of statements about dreams that passed in Brazil. This way, according to the production of conditions, and considering the emergency of these statements, this research intends to identify, select, describe and interpret what it is said and the ways of saying about this object. To better exposure the aims of this work, it should be added that the study in question has a perspective: i: draw a speech panorama about dreams in different production conditions in the long historical duration, in order identify what is preserved, it resumes, updates, develops, and transforms, into similar statements produced in Brazil during the COVID 19 pandemic.; ii. to understand the discursive processes of statements about materialized dreams during the coronavirus outbreak, aiming to verify whether they reproduce, reformulate (in various ways: as of additions, omissions, inflections, etc.), or erase discourses about dreams produced under historical and social conditions of trauma; iii. Describe, and interpret some statements in their relationships with the emotions in speeches about materialized dreams in Brazil in the pandemic period to signal the presence and agency of sensations and emotions in discourse, phenomena central to the constitution of subjects and meaning, particularly in discursive production tied to collective trauma. For so much, this study uses the theoretical and methodological foundations of Speech analysis, from Foucault's discursive studies and the "new" historiographical currents, as sensitivity of History. As for the results, we basically observe how the experience of dreaming, the dream narrative and the interpretation of this phenomenon, as well as its senses, values and functions, they are closely linked to historical, politics and social events, in other words, we see how, in different social formations, the discourses about dreams are build, updated, resumed, transformed and silenced. Especifically, during the pandemic time, we saw how certain speeches authorized some subjects, considered qualified entering the order of speech and take a position of contemporary dream interpreters; we learn how she/woman , health professionals, and teachers general population and health/education workers, they formed a privileged group of dreamers; and we identify how in exceptional times, certain leaders can penetrate dreamlike productions to represent power relations, the struggles and systems of domination of a certain social formation. Finally, we learned how certain speeches about dreams highlighted the affections and/or states of fear, destitution, depression, and happiness.

The relationships between the two constructs of Emotional Intelligence (EI) and Mindfulness became a major focus of study in the early 2010s. Since then, numerous studies have delved deeper into EI, as well as quantitative research aimed to connect EI with the descriptive characteristics of mindfulness. In this context, this research sought to complement these findings through subjective analysis, comparing data collected in semi-structured interviews with the four EI factors defined by Mayer, Salovey, and Caruso. Participants' accounts identified statements that contribute to the connection between these factors and the emotional characteristics developed through mindfulness.

El propósito de esta tesis doctoral es analizar las formas en que es ejecutada la apropiación literaria como procedimiento estético en la poesía venezolana contemporánea, a partir de las obras: Friedrich Hölderlin: cantos hespéricos según la edición histórico-crítica de D.E. Sattler / traducción y versiones libres (en lienzo y poemas) (2015), de Verónica Jaffé (1957); Otono (sic) (2017), de Luis Moreno Villamediana (1966) y El hilo atroz (2021), de Beverly Pérez Rego (1957). Cada una de estas obras, vistas como laboratorios de experimentación estética y lingüística, desestabiliza los conceptos de propiedad, autoría y originalidad. En ellas son tomados distintos materiales de diversos autores para su organización y montaje, lo que provoca un tránsito de operaciones como la traducción, la reescritura, el pastiche, la citación, la referencialidad y la intervención, las cuales sacan a la poesía de un solo cuadro de referencia, poniéndola a dialogar con otros lenguajes (pinturas, mapas, fotografías) y tradiciones. Propongo, por medio de la agrupación de este corpus de estéticas similares, indagar en las operaciones anteriormente mencionadas, en busca de generar una clasificación de divergencias y semejanzas apropiativas entre los casos, discutiendo los conceptos de propiedad y autoría, e integrando, con ello, a la poesía venezolana en este debate actual. Asimismo, busco realizar un mapa de casos apropiativos en la poesía venezolana, partiendo del siglo XIX al XXI para entender de forma diacrónica cómo funciona la apropiación en su contemporaneidad, procurando un acercamiento crítico a su tradición para la revisión del fenómeno apropiativo, el cual, en una desfiguración de los géneros literarios con gestos de reinvención, cambios, parodias y actualizaciones, transforma referentes culturales derivados de distintas disciplinas y saberes para su instalación en las obras. Finalmente, busco hacer énfasis en la traducción como un procedimiento que deviene de la apropiación, el cual se reitera, con diferentes rasgos, en los casos a ser analizados.

Due to adverse environmental effects and the variable efficacy of chemical control methods, there has been a growing development of products derived from biocontrol agents for plant health management, with particular emphasis on growth-promoting rhizobacteria of the Bacillus genus. Accordingly, the objective of this study was to investigate the use of Bacillus as a management strategy for soybean seed treatment through a bibliometric analysis, and to evaluate the physiological potential of soybean seeds and the biostimulant effects of commercial formulations based on Bacillus spp. in relation to storage duration and environmental conditions. For this purpose, an exploratory bibliometric analysis was conducted over a 25-year period (2000 to 2024) on the topic of soybean seed treatment with Bacillus spp., and experimental trials were carried out with five seed treatments (B. amyloliquefaciens PTA 4838; B. subtilis CNPSo 2657; B. firmus I1582; abamectin; imidacloprid + thiodicarb) plus a control, under two storage durations (initial analysis and 180 days). For the latter period, the effects of storage in a chamber under controlled conditions (10°C and 40% relative humidity) and under uncontrolled conditions were analyzed. The results of the bibliometric analysis revealed a diversification of applications starting in 2014, with a growing trend in the use of these microorganisms for the management of fungal diseases and nematodes, with B. subtilis being the most extensively studied species. Regarding the second line of investigation, the application of commercial products based on Bacillus spp. resulted in significant reductions in the incidence of Aspergillus spp., improved final seedling germination, germination speed index, laboratory emergence speed, and biostimulant effects, including increases in root system length and dry matter of both shoots and roots, across both storage periods and under controlled environmental conditions. Moreover, under simulated water deficit conditions, Bacillus spp. was able to maintain the physiological potential of seeds in terms of germination variables and root system length. Temperature and humidity control were decisive factors in preserving the physiological potential of the seeds. The information regarding the effects of Bacillus spp.-based products on seed physiological performance may support integrated management programs in achieving better seedling development outcomes while aligning with the environmental requirements of sustainable production systems.

Corpus annotation is a cornerstone of Natural Language Processing (NLP), providing the foundation for training and evaluating Machine Learning systems, as well as for investigating linguistic behavior in various domains. A key challenge in this area is the annotation of Named Entities (NEs) in user-generated content (UGC). The informal language and a wide range of platform and domain-specific phenomena found in tweets demand highly adapted annotation methodologies. This dissertation addresses this challenge by conducting an independent reannotation of the DANTEStocks, a Portuguese corpus of 4,048 financial market tweets (84,396 tokens). While a previous annotation based on the 10 general categories of the Second HAREM existed, our work expands this taxonomy to a more granular set of 47 types. This was achieved by refining the original guidelines based on linguistically motivated decisions and by introducing four new domain-specific types: certificate, indicator, ticker, and user. The annotation was carried out by a single annotator using a semi-automatic approach that combined rule-based methods with manual curation, resulting in a new reference annotation and a comprehensive set of guidelines. The resulting annotation comprises 20,092 entities (24,825 tokens). A detailed characterization of the corpus revealed a linguistic profile dominated by single-token (i.e. those consisting of a single word) entities and by specific stock market types such as ticker, money, and virtual. The main contributions of this work are therefore: the enrichment of the DANTEStocks corpus with a fine-grained NE annotation, a set of guidelines for annotating UGC, and a discussion of the strategies developed to overcome the inherent challenges of this task.

This dissertation aimed to understand how the psychological suffering experienced by technical-administrative staff at public universities is instrumentalized by New Public Management. Grounded in the theoretical framework of the Psychodynamics of Work, the study starts from the hypothesis that defensive strategies, far from being mere side effects of precarization, can be appropriated as mechanisms for intensifying and controlling work in a context marked by the dismantling of labor conditions, workforce, and career structures. The research was conducted at two public universities through semi-structured interviews with eight technical-administrative staff experiencing work-related suffering. The data were analyzed using Work Clinical Analysis and Thematic Content Analysis. Examination of institutional structures and participant narratives revealed that experiences of suffering emerged in various forms of organizational violence and were intensified by managerial strategies that operationalized the dialectic of exclusion/inclusion, the banalization of social injustices, and subjective precarization. Furthermore, practices such as moral harassment, work overload, academic authoritarianism, and the erosion of technical-administrative identity not only produced suffering but also reinforced performance and submission to alienated labor, even in the face of increasing precarization. The dissertation concludes that, within universities influenced by New Public Management, the instrumentalization of suffering becomes a low-cost, high-return mechanism for maintaining academic productivism – which, in turn, is elevated to a survival imperative amid budget cuts and growing dependence on private funding and support from research funding agencies.

As a consequence of the increasing production and use of synthetic organic compounds, a growing detection of these pollutants has been observed in water bodies. Depending on their concentration and exposure, these substances may pose risks to human health and aquatic life. One of the main factors contributing to their presence is the inefficiency of conventional treatment methods, which are not effective in removing such compounds. In this context, the present study investigated the efficiency of UVC-based advanced oxidation processes for the simultaneous removal of four micropollutants: ciprofloxacin (CIP), enrofloxacin (ENRO), norfloxacin (NOR), and imidacloprid (IMD). Two systems were evaluated: UVC/H2O2, as a source of hydroxyl radicals (HO•), and UVC/S2O82–, as a combined source of sulfate (SO4•–) and HO• radicals. For the three fluoroquinolones, a concentration of 500 μmol L–1 of H2O2 provided the best results in terms of oxidation rate and oxidant consumption. In the case of the UVC/S2O82– system, its performance was similar across all tested concentrations, allowing the same value to be used for comparison. Overall, the UVC/S2O82– process showed superior performance compared to UVC/H2O2 in the oxidation rate of fluoroquinolones. On the other hand, the oxidation of IMD was not significantly affected by the different oxidant concentrations, resulting in similar oxidation rates for both processes and being primarily dependent on the photochemical process. The efficiency of both systems was also evaluated in different aqueous matrices: deionized water, tap water, and simulated effluent from a biological wastewater treatment plant. In the UVC/H2O2 process, a slight inhibition in the degradation of micropollutants was observed in the more complex matrices, especially in the simulated wastewater, likely due to light attenuation and the consequent decrease in oxidant activation. In contrast, in the UVC/S2O82– system, both the oxidation rate and oxidant consumption remained similar across all matrices, demonstrating greater robustness and versatility in the presence of matrix interferences. Toxicity assays using Escherichia coli indicated that although UVC irradiation alone achieved a good oxidation rate, it was not effective in removing the residual toxicity of fluoroquinolones. In contrast, the UVC/H2O2 and UVC/S2O82– processes proved effective in reducing toxicity, reinforcing their potential for application in advanced treatment of effluents containing emerging contaminants. Finally, process cost was shown to be largely dependent on the lamp power and the type of pollutant targeted for oxidation.

Dans le marché contemporain, il y a une circulation croissance de déclarations d'adhésion sur des objets quotidiens tels que les T-shirts, dont le langage mobilise des significations sociales et identitaires. Dans cette étude, nous proposons d'analyser, sur un site web, comment les significations de la parentalité sont configurées dans les énoncés adhérents imprimés sur les Tshirts Digorestte, en nous appuyant sur l'Analyse du discours dans une perspective énonciative, et notamment sur les apports théoriques de Dominique Maingueneau (2013, 2015, 2020, 2022). Nous cherchons ainsi à comprendre comment les énoncés adhérents sur la parentalité actualisent des pratiques discursives qui traversent l'espace public et la consommation, et comment ils construisent un ethos qui interpelle les sujets-mères et les sujets-pères. L'analyse est guidée par les questions suivantes : comment les énoncés adhérents sont-ils planifiés à l'avance par le site de la marque pour interpeller un sujet encore générique ? Comment s'établit l'adhésion entre les dictons et le support du tee-shirt, surtout dans un moment qui précède l'appropriation individuelle - ce que nous proposons d'appeler la pré-adhésion ? Enfin, quels réseaux interdiscursifs traversent ces énoncés et soutiennent les formes de reconnaissance sociale de la parentalité ? Pour traiter ces réflexions, nous avons également mobilisé les contributions d'auteurs tels que Neyrand (2011), Zornig (2010), Butler (2004), Schneider (2011), Campos et Tílio (2020) et Bauman (2001), avec lesquels nous avons discuté des notions de parentalité, de performativité, de reconnaissance et d'idéologie. L'analyse montre que les énoncés des adhérents sur la parentalité agissent comme des dispositifs discursifs qui (re)produisent des normes sociales et des valeurs associées aux soins, à l'autorité et à la protection, mettant en tension la place des pères et des mères dans la société contemporaine.

Air quality and reuse of plastic waste are two problems that have challenged humanity and the terrestrial ecosystem. Expanded polystyrene (PS-E) can be recycled to produce air filtering media to, simultaneously, address these two problems. Thus, this work had as objective to develop air filters from recycled PS-E produced via electrospinning. Process variables such as polymer concentration, spinning time, type of collecting substrate, and the addition or not of ionic surfactants were investigated. The influence of the collecting substrate on the formation of nanofibers was observed, the nylon mesh resulted in a reduced area of fiber deposition and incomplete evaporation of solvent. Samples spun on steel mesh maintained surface electric potential (TES) even after 30 days, while those electrospun on copper mesh have their surface voltage completely dissipated after 7 days. An atypical phenomenon was observed in some samples that presented momentary increase of TES, possibly related to the surface redistribution of charges. Electret filters presented overall efficiencies higher than 90% for particles with average diameter of 0.25 μm (MP0,25), with quality factors (QFs) varying between 0.035 and 0.064 Pa⁻¹. However, after electrostatic discharge, the overall efficiency was reduced to values between 52.26% and 76.89%, and the QF decreased to the range of 0.008 to 0.024 Pa⁻¹. The polarity of the voltage applied during electrospinning does not appear to have effect on the collection efficiency, but affects the morphology of the fibers, with the samples of negative polarity presenting greater occurrence of structural defects. The addition of ionic surfactants cetyltrimethylammonium bromide (CTAB) and sodium dodecyl sulfate (SDS) resulted in absence of TES (0 kV), indicating that the increase of the conductivity of the solution facilitated the escape of the charges. Despite the absence of the electret character, these filters exhibited high collection efficiency, higher than 99.2% for MP0,25. Moreover, the formation of self-assembling fibrous stacking as well as the presence of electrowebs was observed. These results contribute to the understanding of production of electret filters and reinforce the possibility of employment of recycled PS-E as raw material for the production of air filtering media.
