This study aimed to understand the trajectories of theatre artists, with particular emphasis on the processes involved in the construction of artistic careers. Careers are understood
as central themes in people’s lives (Mayrhofer et al., 2023), situated at the intersection of societal history and an individual’s biography (Grandjean, 1981; Gunz et al., 2019). Accordingly, this study assumes that careers are not merely products but can also be interpreted as processes marked by critical events (Baruch; Sullivan, 2022), which shape
individuals’ experiences across time and space. A systematic literature review revealed that organizational studies have devoted insufficient attention to work associated with
creativity (Soares; Saraiva, 2019; Bendassolli et al., 2009). From a social perspective, the study is justified by the fundamental role of theatre in fostering cultural development and
preserving social memory. Considering that careers can be understood as processes embedded in specific contexts and that the concept of career is permeated by social,
economic, and political dimensions (Gunz; Mayrhofer; Tolbert, 2011), the following general objective was established: to understand how the career trajectories of theatre
artists in the city of São Paulo unfold, analyzing the meanings they attribute to their professional experiences and the objective and subjective factors that influence their
decisions and challenges across different socio-historical contexts. To achieve this objective, the following specific objectives were established: to analyze the sociohistorical and legal context of theatre artists’ careers, situating the careers of the interviewees within the contexts in which they work; to characterize theatre artists’ occupation, with particular attention to the professional experiences of the research participants; and to examine the participants’ life trajectories in relation to their objective and subjective dimensions, identifying the occurrence of critical events. Regarding the methodological procedures, this study adopted the life history method, given its potential to facilitate the reconstruction of the past through reflection, imagination, and language (Barros; Lopes, 2014). The main findings revealed that the participants develop their professional trajectories within a context characterized by informality, the need for selfmanagement, and significant dependence on funding mechanisms provided through public calls for proposals. Furthermore, these careers are shaped by continuous and intensive learning processes involving character development and in-depth artistic research. The findings also highlight the essentially collective nature of these trajectories (Barley, 1989), which are structured through networks of cooperation (Becker, 2010). Finally, theatre artists mobilize the political dimension of their careers (Gunz; Mayrhofer; Tolbert, 2011) as a strategy to claim rights and reaffirm identities that extend beyond the individual sphere, thereby assuming a collective dimension as well.

Percepções de professores acerca do papel da coordenação pedagógica: qual o lugar da formação docente?
(Universidade Federal de Lavras, 2026-02-27) Dias, Luana Aparecida Soares Rego; Lima, Francine de Paulo Martins; https://orcid.org/0000-0002-9646-8235; Silva, Bethânia Bittencourt Costa e; https://orcid.org/0000-0002-7879-8900; Calil, Ana Maria Gimenes Corrêa; https://orcid.org/0000-0002-4578-0894
Pedagogical coordination plays a central role in the school context, especially with regard to articulating teaching work and promoting the continuing professional development of teachers. However, in everyday practice, this professional often has their functions shifted toward bureaucratic and administrative activities, which compromises their role as a trainer. In this scenario, the present study aimed to investigate teachers’ perceptions of the role of the pedagogical coordinator in a state school located in a municipality in the state of Minas Gerais, seeking to understand the extent to which this function has contributed to teacher education in context. This is a qualitative, exploratory study, whose data were produced through questionnaires and interviews with approximately 28 teachers working in different segments of the school (Elementary Education I, Elementary Education II, and High School), and 02 pedagogical coordinators. Data analysis was conducted based on the assumptions of prose analysis, organized into analytical categories constructed a posteriori, namely: (i) teachers’ understanding of the role of the pedagogical coordinator; (ii) pedagogical monitoring practices; (iii) interpersonal relationships and conflict mediation; (iv) continuing professional development in contexto; (v) the role of pedagogical coordenation ande the improvement of teaching work. The results show that teachers recognize the pedagogical coordinator as a professional who is fundamental to the organization of school work; however, they associate their role mainly with administrative, disciplinary, and emergency support functions, to the detriment of systematized formative actions. In the category related to pedagogical monitoring practices, the presence of occasional interventions was observed, mainly aimed at solving immediate problems, with little formative intentionality. Regarding interpersonal relationships, teachers highlight the coordinator as a mediator of conflicts and a link between management, teachers, and the community, reinforcing their articulating role, although overloaded. Finally, in the category of continuing professional development in context, a significant gap was found between the formative role theoretically attributed to pedagogical coordination and its effective materialization in everyday school life, limited by lack of time, excessive bureaucratic demands, and the absence of institutional support policies. As an educational product, pedagogical letters were developed with the aim of promoting reflective processes on the practice of the pedagogical coordinator, contributing to the strengthening of their identity as a teacher trainer and to the re-signification of their role within the school.

Challenges and barriers faced by older adults to access legislative e-participation platforms in Brazil
(2023-05-22) Junqueira, Luiza; Freire, André Pimenta; Grützmann, André; Zitkus, Emilene
With the steady increase of the aging population in Brazil, older adults demand government services and actions more than ever. The present exploratory study analyzed the challenges and barriers faced by older adults when accessing legislative e-participation platforms, considering whether the challenges would interfere with these citizens' empowerment. The study employed qualitative evaluations with 20 participants over 60 years old on the e-Cidadania and e-Democracia platforms. It involved responding to a questionnaire, using the platform—while usability tests and observation were conducted—and a post-test interview. The results showed that, in general, the participants were interested in contributing to the e-participation platforms and considered that these systems provide representativeness to them. However, the negative aspects of the design contribute to skepticism among older adults, which can demotivate them to use the resources. The results highlight how the interface features reinforce participants' distrust in the government and distrust in the e-participation process as soon as they realize the information and language are complicated and the resource is difficult to use. They stressed that a more accessible language and a simplified organization of web pages could facilitate the use and boost older people's engagement with these platforms. The results provide reflections on the design of e-participation systems and processes to promote real political participation of older adults in society. Although the study is not representative of the Brazilian older adult population, the qualitative findings and recommendations were delivered to the Accessibility commission of the Brazilian Chamber of Deputies and have been used for guidance and improvements in the platforms.

Cellulase adsorption on pretreated sugarcane bagasse during enzymatic hydrolysis
(2023-08-16) Moreira Neto, João; Machado, Daniele Longo; Bonomi, Antonio; Gonçalves, Vinicius Ottonio O.; Martins, Luiza Helena Silva; Costa, Josiel Martins; Costa, Aline Carvalho
The enzymatic hydrolysis of lignocellulosic biomass has become attractive for obtaining ethanol. Therefore, optimizing its conditions and revealing the main influencing factors are essential for an effective design. In this sense, this study evaluated the influence of cellulose conversion on the Langmuir isotherm parameters in cellulase adsorption on sugarcane bagasse pretreated by hydrothermal and organosolv methods. The adsorption isotherm assays were performed with commercial cellulase from Trichoderma reesei in Erlenmeyer flasks stirred at 150 rpm and 50 °C. Isotherms were determined for enzymatic hydrolysis substrate samples of hydrothermal bagasse (HB) and organosolv bagasse (OB) at 0, 1, 6, and 18 h, respectively. The Langmuir model represented well the experimental data for the cellulose–cellulase system.
The study of cellulase adsorption on HB and OB demonstrated that the maximum adsorption capacity (Emax) decreased during the reaction. From 0 to 18 h of hydrolysis, the value of Emax decreased from 37 ± 3 to 23 ± 2 mg cellulase/g HB and from 29 ± 1 to 25 ± 2 mg cellulase/g OB. Therefore, the adsorption of cellulase on a substrate varied during hydrolysis and its representation was expressed by an empirical equation related to the cellulose conversion and the Langmuir parameters.
