This dissertation explores the essential role of Transport Layer Security (TLS) in securing web applications. Our focus is on exploring the potential of kernel TLS (kTLS) offloading to alleviate resource usage, including CPU time, power consumption, and communication speed. Our main objective is to assess the viability of kTLS offloading, both in software and hardware configurations, to enhance resource efficiency in securing web applications. A variety of offloading strategies are analyzed, such as software-based kTLS implementation that brings cryptographic tasks closer to the Kernel and cutting-edge hardware-accelerated modes such as TOE (TCP Offload Engine) and coprocessor configurations, where we used the Chelsio T6 SmartNIC. We highlight the immense potential of kTLS and network adapters in reshaping performance and efficiency dynamics for some network environments, considering each approach's benefits and potential drawbacks. One challenge identified is the complexity of implementing kTLS in the current context. The discussion digs into the implications of this challenge and its potential impact on the broader adoption of kTLS in real-world applications. To address the difficulty of implementing kTLS and to ease legacy applications in taking advantage of the benefits of hardware offloading, the dissertation introduces Aludel. This solution provides a mechanism for legacy applications to seamlessly support kTLS, even without such support, giving interesting results on resource usage.

Since the 1990s, theoretical/practical/methodological strategies linked to territorial and community contexts have emerged in the teaching of occupational therapy in Brazil. Focusing on the teaching-learning process, these contexts are living spaces involved in the production of knowledge and practices, composed of a confluence of knowledge and actions that reflect the plurality of trajectories of Brazilian occupational therapy, in health, education, arts, in culture and society. Thus, this research aimed to present a current panorama of teaching focused on territorial and community contexts in graduate training in occupational therapy. As a methodological resource, we used documentary research based on national curricular guidelines, pedagogical projects of participating courses and teaching plans. In addition to virtual questionnaires and conversation circles with teachers. The data was presented, organized and analysed using thematic analysis. The results demonstrate that territory and community are structuring concepts of this teaching, they are incorporated into the documents guiding training in the country, but they dialogue with the concepts of social participation, ways of life, territoriality, urban mobility, interculturality, structural racism, popular education, rights humans, among others. Training in these contexts incorporates teaching and professional practice as elements for transforming social, cultural and health realities. In this conjunction, this teaching incorporates practical rationality in graduate training, encouraging critical and ethical reflection within the territories, being built in the dialogical relationship between students, teachers, teams, services, professionals and communities. It is organized by curricular components that present content in a transversal way, but five of them address the topic in a specific way. Most of the training actions are linked to the practical components of the curricula, which present professional practices, supervised internships and extension actions in the territories. We concluded that the research brought elements about/for this teaching in the Brazilian context that contribute to the training of occupational therapists committed to social transformation and territorial actions. In this way, in contrast to technical rationality, this training requires practical rationality, relying on situated and reflective learning, being fundamental for the subareas that support it, but also for all practices of the profession, even if the professional can later specialize- and for actions in other specific contexts.

This research stems from the results of Milozo (2019) work , “Translingual practices in the communication of learners of Portuguese as a foreign language”, which investigated the language practices of five multilingual speakers in a Portuguese language course. Aiming to analyze the dimensions that construct the translingual space, highliting affectivity, this work is justified by the fact that emotions, feelings and affections belong to transcultural and situated domains, which was also perceived in the work of Milozo (2019). The research problem leads to a deeper understanding of the impact of affectivity (Bottura, 2019; Dhokotera, 2019; Dovchin, 2021; García, 2021; Takaki, 2023) on language practices. Under the guidance of the interpretivist paradigm, the methodology used was secondary analysis (Heaton, 2008; Chatfield, 2020), in which previously published data from another research were analyzed. The theoretical apparatus based on translanguaging (Canagarajah, 2011; 2013; Wei, 2011; 2017; 2018; García, 2012; 2015; 2017; 2021; Rocha; Maciel, 2015; Rocha; Megale, 2023), on the linguistic repertoire (Busch, 2012; García; Johnson; Seltzer, 2017; García, 2020) and on decoloniality (Maldonado-Torres; 2000; Quijano; 2002; Walsh, 2012; Mignolo, 2020; Queiroz, 2020; Santos, 2022) is the basis for the analysis. In order to achieve that, a transdisciplinary (Nicolescu, 1999; 2005; 2010) and ecological (Van Lier, 2010; Kramsch; Steffersen, 2017) perspective on the data was necessary, based on theoretical reflections that has knowledge as similar to a rhizome ( Deleuze; Guatari 1995). As a result, the dimensions of the translingual space initially proposed by Wei (2011) were expanded, resulting in five dimensions: physical capacity, cognitive capacity, social capacity, identity aspects and affectivity. Such dimensions become levels of reality (Nicolescu, 2010), in which the individual perspective intertwines with the objective and surrounding reality. Finally, the “critical moments” (Wei, 2011) that emerge in the translingual space characterize the dichotomies of self/other, colonial/decolonial, individual/collective, among others, and are related to the dimension of affectivity, influencing the linguistic repertoire and the process of teaching-learning. Keywords: Translanguaging. Transdisciplinarity. Affectivity. Teaching-Learning.

During adolescence and early adulthood, social interactions intensify due to exposure to new environments, stimuli and the building of more lasting relationships, leading to greater autonomy and social interaction. In the area of social skills (SS), making friends involves a class of behaviors that can be taught and evaluated in educational interventions. The study aimed to evaluate the effect of PEERS (Program for the Education and Enrichment of Relational Skills) with young people with autism and/or intellectual disability (ID), in the context of the São Paulo metropolitan region, using neurophysiological measures (cerebral asymmetry) analyzed by electroencephalogram (EEG) and behavioral measures (for example, asking and answering questions on and off topic, spontaneous behavior on and off topic, among others). The program was applied to six young people (one with autism, three with autism and ID, two with ID) in 14 sessions. Behavioral measures were analyzed during the intervention, while brain symmetry was analyzed as a function of pre-test, intermediate measure (after the 7th week) and post-test. The results showed that the young people exhibited more social skills during the intermediate sessions and the EEG results showed greater activation in the left hemisphere than in the right in the intermediate measurements, as expected by the study. The program needs to be improved, especially in terms of intervention time and ensuring family involvement.

Children diagnosed with Autism Spectrum Disorder (ASD) often engage in repetitive and solitary activities and exhibit a significant deficit in the repertoire of symbolic play. Symbolic play is crucial for the development of social, cognitive, language, and emotion expression skills. The present study aimed to evaluate an intervention procedure using interactions with real objects to teach or enhance the attribution of pretend properties to mock (non-real) and arbitrary objects. Six children diagnosed with ASD, aged 4 to 7 years, participated, interacting with real objects and were asked to tact the sensory properties during the intervention. Corresponding test objects, the mock objects (e.g., a toy candy) and arbitrary objects (e.g., blue tissue paper), were used to assess whether the responses of tact sensory properties would transfer. A multiple probes design across objects was employed. The results indicated that one child emitted tacts of stimulus properties for all three test objects presented, and one child emitted tacts of stimulus properties for one of the test objects. Another participant showed an increase in tacts of sensory properties in two items compared to the baseline. One participant maintained the initial performance, and two participants had their data collection interrupted. The application of resources and efforts in an experimental study on this theme aims at the development of teaching procedures that can be useful for professionals working with intervention for children with ASD.

The family plays a fundamental role in the development of language and communicative and social processes of their children with Intellectual Disability (ID) and/or Autism Spectrum Disorder (ASD). The general aim of this study was to analyze the use of the Evaluation Scale for Oral Language Teaching in the Family Context (EVALOF) in the context of young people. A specific objective was set to relate the family routines of young people with ID and/or ASD to the strategies used by mothers in communicative interaction, via EVALOF. Eight young people with ID and/or ASD aged between 13 and 23 and their families, represented by seven mothers and one sister, took part in the study. Two instruments were used to collect the data: Family Routine Based Interview and EVALOF. The study analyzed: 1) Qualities and difficulties of young people from the mothers' and sister's perspectives; 2) Social interaction and life in the community; 3) Family routines and satisfaction and 4) Communicative interactions and family support, via EVALOF. The analysis of the EVALOF applied to young people guided structural changes to the instrument, such as adaptations to the glossary according to the age group. The results showed that, although all the families offer some natural support to facilitate young people's communication, especially in the organization of the environment, there is a lack of specific strategies to improve communication skills. The strategies used by families were: organizing the environment, adapting the physical context, facilitating attention to young people, encouraging young people to participate in communicative interactions, responding to interactions initiated by young people, supporting them in obtaining information, expanding young people's utterances and teaching communicative skills. The study highlighted the importance of family strategies and the need to strengthen the teaching of specific communication skills to improve the interaction and oral language development of young people with ID and/or ASD.

This study redeveloped a similar pharmaceutical product with a combination of two active ingredients in the form of an injectable solution. The experimental part used the Quality by Design (QbD) approach with the aim of obtaining a greater understanding of the product and process, aiming to reduce the risks of deviations during the commercial manufacture of the medicine. Due to the difficulty of stabilizing the content of one of the active ingredients, which is labile in solution in the presence of heat, light and oxygen, this redevelopment presents a considerable challenge, therefore, the use of QbD is recommended. Formulation and process variables with potential impact on product quality attributes were defined using the Cause and Effect Matrix risk analysis tool. Over time, forty-nine experiments were carried out on a laboratory scale (6.5 L) using experimental planning (Design of experiments, DoE), with the aim of defining and optimizing qualitatively and quantitatively the excipients and evaluating the impact of the variables of process. All formulations were analyzed immediately after carrying out the experiments and after exposing the samples to a forced degradation study (60°C/75%RH for 14 days). The responses (Critical Quality Attribute, CQAs) evaluated in the experiments were: reduction in the content of the two active ingredients and less formation of impurities after forced degradation studies. The experiments demonstrated that: (i) active 1 is stable and the variables are irrelevant at the levels tested, (ii) the presence of antioxidant excipients 1 or 2 reduces the degradation of active 2 and the formation of its known impurity, without differentiation between them , with excipient 2 being defined because it is used in another company medicine and historically stable and (iii) the formulation with potassium salt was defined since experiments with this salt had less formation of unknown individual impurities of active ingredient 2. New experiments were carried out to quantitatively verify the two excipients defined in the first screening study and experiments were carried out evaluating the critical process parameters, and in the range studied, robustness was observed in the process, that is, no variable proved to be relevant.

Studies indicate that the textile fashion production chain is responsible for several social and environmental impacts across the planet. In this context, consumerism, or consumer society, is identified as the core of the main problems related to the link between fashion and the environment. Although environmental issues are currently being discussed in the media, there is still a gap in studies on critical environmental communication. This exploratory research aimed, therefore, to answer the following main question: how does transparency in communication about the socio environmental impacts generated in the stages of the fashion production chain influence consumer behavior? To answer it, five studies were proposed that complement and interrelate with each other, each dealing with the following aspects: 1) the objective was to seek, through bibliographical research, information on the relationships between fashion and socio-environmental impacts; 2) the objective was to analyze content from two different communication spaces, scientific articles and documentary films, through which data were collected on peculiarities present in environmental narratives; 3) the objective was to provide information about the corporate communication policy of four companies in the clothing sector (Lojas Renner, C&A, Pernambucanas and Riachuelo), through the analysis of sustainability reports; 4) the objective was to gather information about the communication of the Algodão Paraíba Project and the Algodão Project in Agroecological Consortia, based on a case study; 5) the objective was to present qualitative data on consumers' knowledge regarding the textile fashion chain and their respective consumption behavior. The results obtained indicate that: 1) there is a need to create a new awareness regarding consumption; 2) scientific communication is limited to a small portion of the population, while documentaries enable a broader and more accessible discussion; 3) three of the four clothing companies analyzed use the Global Reporting Initiative (GRI) indicator in their reports, which suggests that pressure from investors leads large companies to adopt more environmentally fair practices and policies; 4) the case study demonstrated alternative models to extensive cotton cultivation and highlighted the importance of communication being well articulated for projects of this nature; 5) 114 women responded to the questionnaire, and the data collected showed that 64.9% do not know who makes their clothes, 50% look for good social and environmental practices when buying their clothing, 49.6% look for information through social networks , and 20.4% still have a lot of doubts about the impacts and the means of obtaining information on the subject. In conclusion, it is suggested that transparency in communication can serve as a device for more conscious consumption. It is expected that the data collected in this study will serve as an element that contributes to the development of environmental education and communication policies. Keywords: fashion chain; socio-environmental impacts; environmental communication; environmental communication policy; sustainable communication.

Lesbians, gays, bisexuals, travesties, transsexuals, queers, intersexuals, asexuals, pansexuals, non-binary, among other people who experience dissidence of genders and sexualities, have their lives marked through violence. This fact can lead to the intensification of fragilities, reconfiguring the organization of these people's everyday lives, with wide-ranging impacts ranging from the sphere of personal, affective and loving relationships (in friendship, family, marital life, religious options) to that social policies (health, education, social assistance, among others). In occupational therapy, work in the field of gender and sexual dissidence is scarce, with almost no bibliographical production on the subject. Taking Judith Butler's reflections on the construction of alliances between groups that aim for social justice – as justice in conceptualized by Nancy Fraser – a theoretical-methodological alliance between social occupational therapy, critical occupational science and queer studies was proposed. Through a survey done to apprehend and analyze the professional profile and practices of occupational therapists who work in Brazil with this public, elements were gathered to support the hypothesis that the work occupational therapists carried out with the population who experience dissidence of genders and sexualities did not bring new resources or technology specific to the professional core. No practices were identified exclusively for the care of this population. It was noted that the professionals used resources already known and established in the field. The main differentiating factor between practices that operated within the logic of adaptation or social articulation were the theoretical-methodological references used. The first stage of the research was a scoping review of journal articles indexed in academic databases and virtual libraries, namely: VHL, CINAHL, SciELO Citation Index, SCOPUS and Web of Science. Considering articles available online until March 2021,39 articles were included in the review. In the second stage, an online questionnaire (2019-2020) to understand practice with this population. Using snowball sampling, recruitment began through seed informants and social media. Based on the responses (n= 95), 15 informants were selected for interviews to enhance depth of understanding of the professional practice developed. Using Laurence Bardin's postulates, we used thematic content analysis to organize and process field data. Even though we can affirm that there are occupational therapists in Brazil working with the population who experience dissident genders or sexualities, when we consider the literature, few productions focused specifically on professional practice. Most articles proposed possible contributions and made general recommendations. Taking these findings, we seek to offer support so that occupational therapy continues to work with the population in question, but also point to the necessity of critical reflection on this field of knowledge and practices. In these assumptions, a complex, diverse profession is defended, with its multiple possibilities of intervention, different vocabularies and objects, but which builds common general objectives focused on people’s participation that requires social justice. Thus, occupational therapy remains a field of borders, but building alliances with references will converge in a reading of the world and the collective task.

The Neotropic cormorant (Nannopterum brasilianum) is an abundant psicivorous bird within its distribution area, especially inside Brazil. Despite its wide ocurrence, the bird ecological aspects are yet not explored by South american scientists. In Laguna Estuarine System (SEL), localized at southern coast of Santa Catarina State, Brazil, tradicional fishing community express nuances of a potential increase in cormorant population and its feeding habitats. This thesis evaluates the species ecological aspects of a populated dormitory at SEL. We assess cormorant population dinamics, diet, estuarine spatial use and reproduction from 2021 to 2023. The region is economically, culturally and historically important to South of Brazil and supports an intense fishing activity, demanding evidence-based evaluation of the interactions between cormorants and fishing resources. Diet analisys revealed diversified and generalists feeding habits, with cormorants consuming pelagic and demersal fishes composed mainly by the next families Ariidae, Engraulidae, Scianidae, Gerreidae e Atherinopsidae. Through otolith analisys sampled by regurgitated pellets, we assessed mean prey sizes of 128,6 +67,6mm and a diary consumption of biomass of 382,2 ±23,5g. Population counts indicated peaks of abundance during autumn and winter, corresponding to the establishment of reprodutive colonies in Laguna adjancies. By direct observations and the utilization of biologgers we observed maximum travel distances of 18 km to feeding areas, but mostly travels ocurred near the dormitory/colony (Nóca Lagoon). We observed a peak of 2780 nests and a reproductive sucess of 56,9% in 2023 colony located at Nóca Lagoon. Here we also document the first conflict between N. brasilianum and artisanal fisheries in Brazil. With ilegal actions and lesgislative responses, exemplified by ordinary law n° 2.154/ 2020. Yet, the conflict lacks evidence-based data and demand holistic and interdisciplinar approaches to its resolution or mitigation of possible negative outputs to biodiversity conservation and sustainable use of natural resources.

Climate change, together with changes in land use, are the main factors that contribute to changes in hydrological processes in river basins. Understanding the behavior of these processes in the face of these changes is of fundamental importance for planning and managing water resources, especially with regard to water availability. This study aims to evaluate how changes in climate variables (temperature and precipitation) interfere with water availability in the Jurumirim river basin (located in Alto Paranapanema) and discuss how future land use may affect or be affected by water availability for basin management purposes. For this purpose, the DinamicaEgo software was used for future land use scenarios (up to 2100) and the Soil and Water Assessment Tool (SWAT) model for hydrological modeling. The SWAT modeling included four climate models (Eta-BESM, Eta-Eta-CanESM2, Eta-HadGEM2-EM and Eta-Miroc5) and two emissions scenarios (RCP 4.5 and RCP 8.5), in the range from 1960 to 2099. The averages of the historical period (1960-1990) of the Eta-BESM model (RCP4.5) were used as a basis for comparison for the other models and periods (2010-2039 - near, 2040-2069 - medium and, 2070-2099 - distant). The land use transitions indicate increases in forestry and urbanization areas and reductions in pasture, native vegetation and agriculture by the end of the century. The reference model presents a historical monthly average of the rainy season between October and March and the dry season between April and September, with higher flows from December to May and lower flows from June to November. Future projections suggest an increase in temperature and an increase in precipitation in the driest months and a reduction in the rainy months, resulting in an annual loss of precipitation in most cases. Climate issues influence water availability more than changes in land use, where climate variables affect flow with reductions in the rainy season and increases in the dry season. In general, the RCP 8.5 scenarios tend to have greater losses and smaller gains compared to the RCP 4.5 scenarios, indicating lower water input into the hydrological system and longer dry periods. The Eta-BESM and Eta-HadGEM2-EM data, which best represent rainfall in the region, point to reductions in water availability, while Eta-Miroc5 shows an increase. Reductions in water availability highlight possible conflicts between multiple uses, which could negatively impact food and energy production and prices. It should be noted that the model has not yet been calibrated, but the results already allow us to understand the dynamics and patterns of rainfall and temperatures in the region.

The well logging phase in oil drilling aims to obtain rock characteristics or properties from indirect measurements acquired by sensors. Typically, these data are characterized by sequences of numerical values representing one or more soil properties. This phase can be executed through various approaches, with two of the most widely recognized and employed being: Logging While Drilling (LWD), which occurs during drilling, and Wireline Logging, which takes place after the well has been drilled. Due to vibrations and other phenomena occurring during drilling, there may be inaccuracies in the depth of LWD logs. To correct this, manual alignment of LWD logs is performed using Wireline logs as a reference. In this context, this work proposes a workflow that performs automatic alignment of LWD and Wireline logs using the Dynamic Time Warping (DTW) algorithm in a segmented manner. The proposed workflow is divided into three parts: finding the common region between the two series, segmenting the LWD and Wireline logs so that the segments are similar, and performing segmented alignment using the DTW algorithm. The results obtained during the experiments in this work demonstrated a significant improvement in the alignment performed by the DTW algorithm when conducted in a segmented manner, resulting in an LWD curve more faithful to the original.

The search for efficient synthetic methods for 5-membered N-heterocycles, such as γ-lactams and pyrroles, is constantly necessary, as these scaffolds are widely found in natural products and synthetic compounds with biological activities. In this aspect, we developed a simple, efficient and diastereoselective synthesis of new γ-lactams from aziridines, based on a previous reported method by our research group for the synthesis of γ-lactones, employing the Horner–Wadsworth–Emmons reaction. We optimized the time, concentration, solvent and the stoichiometric proportion of substrates, and the best reaction condition was stablished using NaH as base in THF at 17 oC for 15 h. We then investigated the scope and limitations of the developed protocol. In total, 15 examples were obtained in 14-88% yield and two limitations observed regarding the presence of the NO2 group and the protected aziridine. Furthermore, it was possible to scale-up the reaction in 10-fold and also initiate the enantioselective version using a chiral organocatalyst. Next, we investigated the synthesis of Δ1-pyrrolines from chalcones and 2H-azirines via photoredox catalysis induced by visible light, under continuous flow regime. Different photocatalysts, solvents, residence time, reactors, concentration, catalyst loading and stoichiometry were tested. The best condition was achieved using blue LED, 7 mol% mesitylacridinium as catalyst in DCE as solvent, which resulted in a Δ1-pyrroline ring with 82% yield and 73:27 diastereoisomeric ratio. After established the best reaction condition, we carried out the investigation of the reaction scope and its limitations. However, the major diastereoisomers of the synthesized derivatives showed low stability in solvents such as chloroform, dimethyl sulfoxide and acetone, which did not allow the efficient characterization of the compounds by NMR. The Δ1-pyrrolines and its pyrrole derivatives showed IC50 between 1.03 and 8.0 µM, in preliminary tests against the protozoan Plasmodium falciparum, in addition, did not show cytotoxicity against HepG2 cells. Thus, the Δ1-pyrrolines were oxidized with DDQ affording seven pyrroline derivatives in 12-47% yield over two steps. The products were sent to be tested against P. falciparum.

Assessing problem behaviors is essential in applied behavior analysis, especially considering its influence on the quality of life of the individual evaluated and the people around them. This thesis aims to fill a gap in the Brazilian context by translating, training, and validating the Semi-Structured Interview-Informed Synthesized Contingency Analysis (IISCA), a type of functional analysis reported to be efficient in informing treatment plans for problem behaviors. The term "problem behavior" is discussed in depth, recognizing its different conceptualizations, through political, social, geographic and topographical influences. The importance of functional analysis is highlighted, highlighting the need for tools sensitive to local culture. In addition to assessment, a behavioral treatment package is presented to address identified problem behaviors, promoting effective and personalized interventions. Three studies are conducted: the first focuses on the translation and adaptation of the IISCA, the second addresses the training of professionals in the application of the interview and the IISCA, and the third focuses on the validation of the IISCA based on the latency of problem behaviors. The results indicate that the translation of IISCA into Portuguese and for the Brazilian public, in addition to presenting adequate results achieving the same objective as IISCA in English, also informs an efficient analysis through the training of Brazilian professionals. In the end, it is possible to understand that latency-based IISCA has the same validity as rate-based IISCA, reducing the number of occurrences of problem behavior in a functional analysis.

The organization of the Health Care Network (HCN) is an inherent component of the Unified Health System (SUS) that ensures comprehensive care, playing a role in a context where primary health care takes on a central role as the care coordinator. Based on this concept, the present research aims to analyze the contribution of responsible hospital discharge in the continuity of care for individuals with Diabetes Mellitus, a chronic disease that affects a significant portion of the population and has important social, economic, and family repercussions. The increasing prevalence of Diabetes Mellitus leads to complications that directly impact the quality of life and functional capacity of patients. Therefore, it becomes essential to verify strategies that ensure continuity of care after hospital discharge. In this sense, responsible hospital discharge is understood as a practice that can facilitate the transition of care, minimizing the possibility of readmissions, and also promoting better adherence and continuity of treatment. The methodological approach used was qualitative, through the application of a semi-structured questionnaire to individuals hospitalized with Diabetes Mellitus. This methodology allowed for an in-depth assessment of the participants' health needs and the effectiveness of care processes related to hospital discharge. The results obtained highlighted weaknesses in comprehensive health care, pointing to the scarce connection between users and health services. The evidence suggests that the lack of a strong bond and active listening results in challenges in the continuity of care, reinforcing the need for investments in primary care. Furthermore, the research points to the urgency of developing effective strategies for the organization of the HCN, promoting continuous qualification of health professionals, and implementing reviews of work processes. Permanent education also stands out as an essential factor for improving care practices, enabling professionals to meet the health demands of the population. These findings not only contribute to the discussion on the importance of comprehensive care but also offer insights for the formulation of public policies aimed at improving health services, especially regarding the care of chronic non-communicable diseases.

In addition to the concern of work and production conditions, criticism of capitalist social formation must turn to the reproduction of the relations of production, as there is no mode of production that can dispense with consideration of its conditions of permanence over historical time. Reproduction is a phenomenon that occurs at the level of everyday life, considered the substratum of social life, from which all human productions and works emerge, alienated or disalienated, alienating or disalienating. A revolutionary process will only occur through the discontinuity of capitalist reproduction and the production of a new society, which will emerge from everyday life. In turn, education constitutes one of the ways through which the transformation of society can occur. Therefore, it is necessary that an educational proposal based on dialectical and historical materialism also assumes the insertion in its theorization of a new vision on reproduction and on everyday life. This research has a conceptual character, that is, it focuses on working with already systematized concepts and categories that reveal reality of public education. The thesis defended here is that school education is a reproductive social instance par excellence, vital to the reproduction of capitalist relations of production, and cannot be easily co-opted by revolutionary forces. It is in this way that we are confronted with the research problem of how to overcome the reproductive character of capitalist school education. To this end, we set the objective of demonstrating that the transformation of school education depends on the transformation of society, which can only occur by centralizing the transformative role of everyday life. We will seek to work on the meaning of social transformation for school education, thinking about how reproduction is related to everyday life which, in turn, cannot continue to be understood as a mere pragmatic and empirical activity, whose functionality to social transformation is limited to its supersumption. We seek to contribute with this research to the collective construction of a counter-hegemonic pedagogical theory, with a scientific socialist character, which seeks to produce a social space favorable to the transformation and compatible with a socialist transition.

Gifted students are the ones who demonstrate ability about average compared to their peers in academic, creative, psycomotor, arts or leadership areas; outstanding creativity and great envolvement with tasks. The attention focused on these students enrolled in regular education schools allows to see that there are a few initiatives on guide, pedagogical support or enrichment guaranteed by Brazilian legislation. One of the forms of attention is the enrichment, which presents as a challenge because it envolves to know the students, their preferences and particularities in order to develop a teaching-learning proposal, in fact, to adapt to them. From this perspective, the research had the general objective of studying and analyzing the curricular enrichment offered by three Education Departments in the inland of the state of São Paulo, Brazil, for gifted students. The study was qualitative, descriptive, and a case study. Three Education Departments (Jaú, São Carlos, São José do Rio Preto) and 42 education professionals participated in the research, including 03 teaching principals, 02 supervisors, 01 administrative director, 10 managers and 26 teachers. The results were: i) few students are identified in the schools, compared to the rates indicated in the literature; ii) despite the rigths to specialized attention, students registered as gifted in those departments do not receive pedagogical actions for their skills or support materials and resources; iii) there is a lack of training on giftedness among participants, because the answers of the source of knowledge about the theme from them were varied; and iv) participants unknow the enrichment, but there were teachers who stated to provide specialized support to the students; v) the review of both national and international literature showed similarities that the gifted students are little recognized and supported in their school enviroments; and vi) students, specifically in the state of São Paulo, need to receive their educational and legal rights. I hope this research will provide the attentive view of the part of managers and educators.

The growing increase in the number of individuals diagnosed with Autism Spectrum Disorders reaching adulthood and entering Higher Education raises the issue of the challenges faced in this age group and in this environment. Among them, one that deserves to be highlighted is the importance of a good repertoire of Social Skills for a good university experience. Considering this scenario, this research aims to analyze the PEERS® for Young Adults program, the Social Skills intervention program for young adults with Autism Spectrum Disorders created by the University of California at Los Angeles - UCLA, making considerations about its application and adaptation to the context of public Higher Education Institutions in Brazil. To this end, qualitative exploratory research was conducted, using documentary analysis with data processing in two phases: the first of Content Analysis, in which analysis categories were created by reading the program manual, and the second of Comparative Analysis, in which the already mentioned Brazilian context and its American equivalent, in which the program is already successfully applied, were compared in the categories created during the first phase. These categories were: structure and content of the program, participant profile, tutor profile, and place of application, with more specific subtopics with which the realities of both countries could be contrasted, seeking to understand the feasibility of application in Brazil. We, therefore, consider that public Higher Education Institutions are a possible application space, however, some adaptations are necessary to take into account the specificities of the Brazilian reality. We hope this work can contribute to ensuring that this intervention program is used in Brazil and that future research is conducted on this theme.

This research is part of a matrix project entitled Collaborative action research to mitigate educational inequalities resulting from the COVID 19 pandemic: contributions from research on school inclusion (PAC-COVID 19), which involved a Program for Professional Development (PPD) organized into five modules, namely: 1) Collaborative Teaching and Inclusive School Culture; 2) Multitier System of Support (SSM); 3) Universal Design for Learning (UDL); 4) Differentiated Teaching Approach (ADT) and 5) Cooperative Learning (CL). The present work concerns module five of the PPD which dealt with Cooperative Learning. This is a research with a mixed methodological approach configured as collaborative action research. Considering the worsening of educational inequalities generated due the emergency remote teaching during the COVID 19 pandemic period, the general objective was to develop, implement and evaluate a Education Program (EP), based on the scientific literature of Cooperative Learning as an Inclusive Education strategy, in order to analyze whether the program offered contributes to providing teaching that better responds to the diversity of students at a target school. The specific objectives were: a) Develop the EP to contribute theoretical and practical knowledge about Cooperative Learning. b) Implement lesson plans based on Cooperative Learning, in classes from the 1st to the 3rd year of primary education at the target school, with the collaboration between class teachers and other EP participants. c) Evaluate the EP based on Cooperative Learning. The reflective critical epistemological core of the investigation was structured in Vygotsky 's historical-cultural approach. The study took place in a municipal public school in the interior of São Paulo, particularly in a Basic Education school, with 37 participants: regular teachers, special education teachers, educational coordinators and professionals from the multidisciplinary team. Furthermore, eight regular teachers applied the lesson plans basead on Cooperative Learning Theory with their 1st to 3rd year classroons of Elementary School. The EP was developed using a remote model, lasting 36 hours, whit synchronous and asynchronous activities. The results showed that the EP had positive impacts on the teachers and students involved, like for example, there were academic, psychological and social benefits for both, which allowed teachers to better respond to the diversity of students. In this way, the universalist and innovative practices such as Cooperative Learning, it enabled the professionals involved in EP to better confront educational inequalities caused by the COVID 19 pandemic in the school researched. Furthermore, in Brazil, the systematization of Cooperative Learning is still incipient, which the current work has contributed to produce evidences, and materials for continued education of teachers and to disseminate the theory in Brazil, that can foster inclusive education and research about Cooperative Learning.

The Federal University of São Carlos (UFSCar), throughout its slightly over 50 years of operation, has undergone profound changes that have greatly impacted its actions, resulting in its way of being, producing and presenting itself, and particularly within the context of Brazilian federal higher education institutions and society in general. These changes have essentially resulted from a process of decision-making and democratization of decisions, within the scope of its Superior Councils, which have been happening since the establishment of the first Superior Council. Currently the University Council, ConsUni, the highest deliberative body at the University, composed of representatives from all categories of the university community, has its decisions taken through a democratic and participatory process. Thus, based on the assumption that many decision-making processes impacted the Institution itself, Brazilian higher education and society, this study has the objective of broadly document how UFSCar’s decision, taken by the University Council, in adhering to the Program for Support for Restructuring and Expansion Plans of Federal Universities (REUNI) occured, seeking to understand the causes of internal reactions to its implementation. Furthermore, it aims to contribute to the recording of history and the pressing need to preserve the memory of UFSCar, given that 66% of teaching and technical-administrative employees have spent less than 15 years at the Institution. Given the unitary nature of the object studied, the methodology used was the case study, through bibliographical and documentary research, the latter being fundamental for the development of the theme and understanding of the internal manifestations that occurred in the process of joining UFSCar to REUNI, as well as understand the national scenario involving the Program launched by the federal government. This research, in another instance, will contribute to studies in Science, Technology and Society (STS), highlighting the importance of interdisciplinarity, and its potential to understand and record the history of the Institution, preserving its institutional memory, in addition to contributing to future research related to the topic.
