As histórias da pesquisa em educação ambiental no Brasil: memórias de um campo complexo e plural
(Universidade Federal de São Carlos, 2026-02-12) Silva, Luiz Gustavo Veríssimo e; Silva, Fernanda Keila Marinho da; https://lattes.cnpq.br/6390725197649567; https://orcid.org/0000-0002-5697-8417; ttps://lattes.cnpq.br/7752066614010991; https://orcid.org/0000-0002-6238-1182; Maciel, Lucas Vinicio de Carvalho; Festozo, Marina Battistetti; Iared, Valéria Ghisloti; Morais, Wanderson Rodrigues; https://lattes.cnpq.br/8779101339709622; https://lattes.cnpq.br/7029045758253180; https://lattes.cnpq.br/1273203310250467; https://lattes.cnpq.br/2328003563888105
In recent decades, we have been living through a global socio-environmental crisis that has raised questions about the ways we relate to the world. This movement has fostered the creation of major national and international conferences and debates related to environmental education, as well as supporting the development of laws, treaties, public policies, and a great deal of research. All of this is part of a history that is almost always the basis for the writing of academic works that address themes related to environmental education. This history is extremely important for the constitution of this field of research; however, when we look at it, we ask ourselves: are there other histories of research in environmental education? To answer this question, we conducted a qualitative study in which we interviewed researchers in environmental education, with the aim of developing understandings about the meanings they produce regarding this field of research based on their memories. The data were analyzed based on dialogic discourse analysis, grounded in the thinking of Mikhail Bakhtin and the Bakhtin Circle. From the articulation between a narrative considered “official” in the history of environmental education, the memories of the interviewed subjects, and our analytical perspective, we constructed three histories: a first one, organized around historical milestones, events, legislation, and data on academic production; a second, composed of the narratives of the researchers; and a third, which emerges from the dialogic analysis of these memories. The results show that research in environmental education in Brazil is constituted as a plural, heterogeneous, and multifaceted field, marked by disputes over meaning, by different political-pedagogical projects, and by diverse educational trajectories. The analyzed narratives show that there is not a single history of environmental education, but multiple histories in which subjects occupy varied positions in the discursive arena that is the field of research in environmental education. The study also highlights the centrality of collectives, networks, and partnership relations in the constitution of researchers’ trajectories, as well as the importance of the subjective dimension, life experiences, and historical contexts in the production of meanings about environmental education and about research itself. By problematizing the official history as an ideological construction that tends to erase conflicts, displacements, and subjects, the dissertation proposes to understand the history of research in environmental education as a permanent becoming. Finally, we conclude that telling histories of environmental education implies recognizing its unfinished, dialogical, and situated character, and that incorporating the memories of subjects makes it possible to broaden and complexify the understanding of the constitution of this field of research in Brazil.
O luto em Freud e suas articulações com a temporalidade na cultura contemporânea
(Universidade Federal de São Carlos, 2026-03-06) Ramos, Vitor Costa; Câmara, Leonardo Cardoso Portela; https://lattes.cnpq.br/0876503068661138; https://lattes.cnpq.br/4957662258663962; Martins, Karla Patrícia Holanda; Risk, Eduardo Name; http://lattes.cnpq.br/0785051938150248; https://lattes.cnpq.br/9006559297031800
The purpose of this dissertation is to investigate mourning from a Freudian perspective, in articulation with contemporary culture, with a focus on the dimension of temporality. This is a theoretical study grounded in psychoanalytic theory. The first chapter addresses the status of mourning in Freud, discussing its metapsychology, the notion of the work of mourning, its main clinical signs, and the question of its termination. The second chapter examines the effects elicited by loss, particularly in the intrapsychic domain and its clinical developments, considering different modes of reaction to object loss that may hinder or prevent the accomplishment of the work of mourning. The third and final chapter proposes an articulation between mourning, temporality, and contemporary culture, prioritizing the relationship between the mourning subject and time. From this perspective, it is understood that the task of mourning takes place at the intersection of the individual and the collective, articulating intrapsychic, intersubjective, and social dimensions. It is observed that the temporality of mourning, which is explicitly subjective, appears antagonistic to the prevailing modes of relating to time in contemporary culture, marked by speed and urgency. The hypothesis advanced is that, in the present context, there is a temporal impasse between the accelerated time promoted by culture and the subject’s subjective temporality. Thus, the time offered to the subject may function as an obstacle to the temporal movement required by mourning, hindering the work of working-through and symbolization in the face of loss.
Relação estrutura–atividade em compósitos à base de cobre: correlação entre composição e atividade bactericida

The phenomenon of antimicrobial resistance drives research into new materials, with copper-based composites showing promise due to their low cost and multiple bactericidal mechanisms of action. This study investigated the correlation between solvothermal synthesis parameters, structural composition, and antimicrobial activity of copper-based materials. A 23 factorial design was used to evaluate the influence of monoethanolamine (MEA) concentration (0.05 and 0.075 M), temperature (120 and 150°C), and reaction time (5 and 20 h). Structural characterization was performed by X-ray diffraction with phase quantification via Rietveld refinement and by HRTEM, while morphology was analyzed by SEM-FEG and optical properties by DRS. Considering the proportional nature of the phases, the data were treated by Compositional Data Analysis, complemented by ANOVA and linear regression. The relative proportions of CuO, Cu2O, and Cu0 varied widely among the experimental conditions, with Cu2O predominating in all tests (>58.8%), while CuO and Cu0 reached maximum values of 34.6% and 33.3%, respectively. ANOVA indicated that the MEA concentration was the main factor associated with phase variation, significantly influencing the formation of CuO and Cu0; for CuO, an interaction effect between MEA and temperature was also observed, while Cu2O showed greater sensitivity to synthesis time. In the case of Cu0, both the MEA concentration and reaction time were found to have an influence. Morphological characterization revealed hierarchical microspheres consisting of nanometric aggregates. HRTEM analysis indicated lattice fringes compatible with the crystallographic planes of Cu2O and CuO, as well as domains attributed to Cu0, confirming the coexistence of the phases identified by XRD. In the biological evaluation, the bactericidal halos ranged from 0 to 2.88 mm and the bacteriostatic halos from 0 to 7.77 mm, the latter being more frequent and extensive. A moderate positive correlation was observed between CuO and bactericidal effect (ρ = 0.48) and a negative correlation with Cu0 (ρ = −0.49). The synthesis routes showed repeatability between independent series, maintaining the majority phase in all tests, and the results indicate an association between compositional variation and biological response in the investigated system.
Entre telas e lacunas: competências digitais entre os alunos da Educação de Jovens e Adultos
(Universidade Federal de São Carlos, 2026-01-30) Silva, Natália da Rocha da; Kerbauy, Maria Teresa Miceli; https://lattes.cnpq.br/4762029784021248; https://orcid.org/0000-0002-0622-1512; https://lattes.cnpq.br/7702854893608191; https://orcid.org/0009-0002-4033-4227; Kerbauy, Maria Teresa Miceli.; Furnival, Ariadne Chloe Mary.; Santos, Vanessa Matos dos.; https://lattes.cnpq.br/4762029784021248; https://lattes.cnpq.br/1291482506649810; https://lattes.cnpq.br/2601633916210576; https://orcid.org/0000-0002-0622-1512; https://orcid.org/0000-0002-2344-4400; https://orcid.org/0000-0003-1041-367X
This study investigates the development of digital competencies among students enrolled in Youth and Adult Education (Educação de Jovens e Adultos – EJA), focusing on individuals who did not complete elementary education during their regular school trajectory. The research is grounded in the understanding that the intensification of digitalization in contemporary society has increased the demand for competencies related to the use of Information and Communication Digital Technologies (ICDTs), thereby deepening inequalities historically associated with low levels of schooling and socioeconomic vulnerability. This is an applied field study with a descriptive design and a quantitative approach, conducted through a data survey. A total of 110 printed questionnaires with closed ended questions were administered to students from two public municipal schools located in the cities of Araraquara and São Carlos, São Paulo, Brazil. The analysis is informed by the Science, Technology and Society (STS) field, articulating the concepts of digital competence, digital exclusion, and Youth and Adult Education. The findings indicate that although internet access is widespread among participants, the development of digital competencies remains limited and uneven. The results highlight the centrality of smartphones as the main device used to access the internet, as well as the predominance of practices related to social media use and video consumption. In contrast, there is limited use of digital tools associated with information production, organization, work-related activities, and citizenship. Significant difficulties in the digital learning process were also identified, linked to both structural and educational factors, such as low educational attainment, limited income, lack of formative mediation, insecurity in dealing with technological changes, and fear of making mistakes or falling victim to digital fraud. Despite these barriers, most participants expressed a strong interest in learning more about digital technologies, indicating that digital exclusion in this context is not the result of a lack of motivation, but rather of insufficient access to continuous and contextualized learning opportunities. It is concluded that digital exclusion goes beyond the issue of access, encompassing limitations in the autonomous, critical, and meaningful use of digital technologies. The findings reinforce the need for integrated public policies that take into account the specificities of Youth and Adult Education, combining access, training, pedagogical mediation, and material conditions in order to promote socially situated digital inclusion.
Entre saberes e fazeres: uma investigação sobre o racismo e o antirracismo nas práticas de terapeutas ocupacionais
(Universidade Federal de São Carlos, 2026-02-23) Amanda dos Santos, Pereira; Lilian, Magalhães; https://lattes.cnpq.br/8695787131933459; https://orcid.org/0000-0003-3666-3685; https://lattes.cnpq.br/4563595279392236; https://orcid.org/0000-0002-3274-7577; Ambrosio, Alekin; Ferigato, Sabrina; Correia, Ricardo Lopes; Nascimento, Ana Márcia Duarte Nunes; https://lattes.cnpq.br/6556176374508575; https://lattes.cnpq.br/3248396158325409; https://lattes.cnpq.br/4167655666171513; https://lattes.cnpq.br/9407089741735527; https://orcid.org/0000-0003-0705-6309; https://orcid.org/0000-0001-7567-7225; https://orcid.org/0000-0003-3108-2224; https://orcid.org/0000-0002-3641-1464
Occupational therapy practitioners have neglected to address the racism that is sustained and reproduced in therapeutic practices. While discussions on ethnic-racial issues have grown in the field in recent years, few studies investigate the theoretical and methodological frameworks that inform the practices of occupational therapy practitioners who work with Black populations and traditional peoples and communities. This study aims to identify, describe, and reflect on the experiences of occupational therapy practitioners working with Black populations and traditional peoples and communities. The specific aims of this study are: 1. To understand how occupational therapy practitioners have provided service to Black populations and traditional peoples and communities; 2. To map the practices of occupational therapy practitioners that address ethnic-racial issues in their therapeutic practices; 3. To identify the conceptual and methodological frameworks that guide the practices of occupational therapy practitioners with Black populations and traditional peoples and communities; 4. To explore the possibilities, limitations, strategies, perceptions, and challenges faced by occupational therapy practitioners in this field of practice; 5. To review the existing knowledge in the literature about how occupational therapy practitioners can take antiracist actions in professional practice. This study was developed by a qualitative approach associated with visual methodologies, using photo-elicitation and semi-structured interviews as data generation instruments. The perspective of Afro-Latin American feminism also informs the methodology of this work. The data were obtained from narratives and photographs produced by six occupational therapy practitioners who develop research, teaching, or intervention with Black people and/or with traditional peoples and communities. The data were analyzed through thematic analysis, resulting in four themes: 1st Theme – Becoming Black: Identity, existential territories, and belonging; 2nd Theme –Academic training and epistemic dispute; 3rd Theme – Racism and its impacts on occupational therapy practices; 4th Theme – The future is here and now! Afrofuturist perspectives. The researcher partners' narratives evidence shows that the presence of institutional and epistemological violence, manifested in the lack of attention to address racism in work teams, the absence of ethnic-racial issues in occupational therapy training, the centrality of Eurocentric curricula, and the negligence in the formulation and implementation of public policies. The researcher partners argue that racism makes the Black population and traditional peoples sick, constituting a direct producer of psychological suffering and social exclusion. Furthermore, they present anti-racist strategies aimed at reorienting the practice of occupational therapy, with a view to strengthening identity, cultural recognition, valuing Blackness, self-esteem, and belonging. From an Afrodiasporic and Afro-Latin American perspective, this study proposes counter-hegemonic strategies and frameworks capable of supporting research, teaching, and the provision of socially relevant services for these populations.
