The growing increase in the elderly population with cognitive impairment highlights the need for strategies that promote the preservation and protection of cognition in this age group. In this context, chess presents itself as a potentially beneficial practice. Objectives: The present study aimed to evaluate the effects of chess training on cognitive ability, mood, and quality of life in a group of older adults attending a Senior Community Center located in a city in the interior of the State of São Paulo, Brazil. Method: The research adopted a quasi-experimental, quantitative approach with a pre- and post-intervention design, involving weekly training sessions. The sample consisted of 25 older adults, of whom 22 completed the study (12 in the Chess Intervention Group and 10 in the Control Group – waiting list, three were excluded due to withdrawal because of health problems.), with three participants excluded due to health-related withdrawal. The classes were structured using the Sessa Platform, which served both as an evaluation tool and as a resource for the systematic teaching of chess. The intervention lasted for six months, with weekly one-hour sessions (24 in total) lasting 1 hour. Data collection instruments included a sociodemographic questionnaire, the Addenbrooke's Cognitive Examination-Revised (ACE-R), the Hospital Anxiety and Depression Scale (HAD), and the World Health Organization Quality of Life for Older Persons (WHOQOL-OLD). Data were tabulated and analyzed using Jeffrey’s Amazing Statistics Program (JASP), version 0.18. Results: The results showed that most participants were female, divorced, belonged to the C2 economic class, and practiced physical activity. The comparison between the pré - and post-intervention moments of the Chess Intervention Group (GIX) revealed a significant improvement in the domain of chess knowledge (p=0.009), as measured by the Sessa platform, reflecting progress in learning and concentration ability. Significant effects were also observed for anxiety symptoms (p=0.008), as well as positive trends in the domains of memory (p=0.062) and visuospatial function (p=0.056). Conclusion: It is concluded that chess may represent a relevant non-pharmacological intervention for the care of cognitive and emotional health in the older population.
História e ficção para jovens leitores: a metaficção historiográfica em "O poeta do exílio"
(Universidade Federal de São Carlos, 2025-11-24) Silva, Amanda Mota da; Bignotto, Cilza Carla; http://lattes.cnpq.br/0782750059258019; https://orcid.org/0000-0001-8295-4251; http://lattes.cnpq.br/5719159019022384
En las últimas décadas, se observa un notable crecimiento en la producción de novelas históricas, cuyas características se distancian de aquellas que marcaron el género inaugurado por Walter Scott en el siglo XIX. Estas obras, con frecuencia, revisitan el pasado con una mirada crítica, cuestionando la objetividad histórica y problematizando las formas tradicionales de representación. Ante este panorama, diversos investigadores, en Brasil y en el exterior, se han dedicado a indagar si estas narrativas contemporáneas derivan formalmente del modelo decimonónico o si se configuran como un nuevo género literario. Sin embargo, una parte significativa de esta producción, las novelas históricas destinadas al público infantil y juvenil, sigue siendo poco explorada por los estudios académicos, a pesar de su potencial para articular conocimiento histórico, formación lectora y reflexión crítica sobre el objeto literario. En este contexto, este Trabajo de Fin de Grado (TFG) tiene como objetivo analizar la novela O Poeta do Exílio, de Marisa Lajolo, investigando de qué manera su construcción narrativa dialoga con las prácticas de la ficción histórica contemporánea, especialmente en lo que se refiere a las aproximaciones a la metaficción historiográfica, tal como la concibe Linda Hutcheon. Para complementar el análisis, se considera también la biografía A Vida de Gonçalves Dias, de Lúcia Miguel Pereira, con el propósito de examinar las diferencias estructurales entre ambas obras y evidenciar cómo la narrativa ficcional se distingue de la narrativa histórica, resaltando sus especificidades. Se busca, así, comprender de qué manera la novela moviliza procedimientos de reescritura y problematización de la Historia, tensionando las fronteras entre hecho y ficción, memoria e imaginación. Partiendo de esta reflexión, se pretende contribuir a la ampliación del debate sobre la literatura infantil y juvenil de carácter histórico, evidenciando su relevancia estética, cultural y formativa en el contexto de la producción literaria brasileña contemporánea, así como su papel en la construcción de una conciencia histórica crítica entre los jóvenes lectores.
Conteúdos digitais viralizados e enganosos: potencialidades para a alfabetização científica e tecnológica
(Universidade Federal de São Carlos, 2025) Milaré, Tathiane; Richetti, Graziela Piccoli; Duso, Leandro; http://lattes.cnpq.br/4030661520659155; https://orcid.org/0000-0001-6557-1769
A desinformação disseminada por conteúdos digitais viralizados tem se intensificado nas redes sociais, demandando uma resposta educativa de maneira crítica. Este artigo analisa vídeos e postagens amplamente compartilhados que abordam temáticas relacionadas à ciência, identificando as potencialidades de sua problematização para a alfabetização científica e tecnológica no ensino de ciências. Fundamentado nos objetivos para alfabetização científica e tecnológica de Fourez (2005) e utilizando a Análise Textual Discursiva, o estudo categoriza os conteúdos segundo objetivos humanistas, sociais, político-econômicos e critérios relacionados à aplicabilidade na educação básica, discutindo como elementos visuais, vocabulário pseudocientífico e estratégias de engajamento digital podem induzir à desinformação. Os resultados apontam que a problematização desses conteúdos pode favorecer a formação crítica dos estudantes, contribuindo para a autonomia, o diálogo argumentativo e o domínio de conhecimentos científicos em contextos cotidianos. Conclui-se que o uso pedagógico de conteúdos enganosos, no sentido de discuti-los e analisá-los, pode fortalecer a educação científica, desde que articulado a estratégias interdisciplinares e éticas.
Tratamento ácido na fermentação etanólica: efeito sobre a viabilidade e vitalidade de linhagens industriais de Saccharomyces cerevisiae
(Universidade Federal de São Carlos, 2025-06-10) Jesus, Gabriel Scanavachi de; Ceccato Antonini, Sandra Regina; http://lattes.cnpq.br/7600793543184032; http://lattes.cnpq.br/7227397272783828; Ceccato Antonini, Sandra Regina; Bastos, Reinaldo Gaspar; Costa, Marcelo Augusto de Souza; http://lattes.cnpq.br/7600793543184032; http://lattes.cnpq.br/9329363278429665; http://lattes.cnpq.br/4776573073140781
The control of contaminant microorganisms in Brazilian sugar-ethanol industries frequently involves the use of sulfuric acid, which, when applied at the end of each fermentation cycle, not only controls contaminant bacteria but also promotes deflocculation of the yeast, contributing to ethanol production efficiency. Few studies have investigated the effect of acid treatment on the yeasts responsible for the fermentative process, particularly regarding viability — understood as the proportion of living cells capable of reproduction — and vitality — defined as the functional and physiological capacity of cells to carry out metabolic activities. In this study, we evaluated the effect of sulfuric acid treatment (pH 2.5; 2 h) on the viability and vitality of Saccharomyces cerevisiae cells, using the industrial strains PE-2 and CAT-1 in fed-batch fermentation with cell recycling, in sugarcane broth, over six fermentation cycles. We analyzed CFU/mL, number of viable cells/mL (erythrosine staining), viability (%), budding (%), growth in liquid medium and counting of bud scars, as well as alcohol content (g/100 mL), final pH, residual total reducing sugars (g/100 mL) and yield (g ethanol/g total reducing sugars) after each cycle of cell treatment. A control fermentation without acid treatment was also conducted, using water in place of the acid. In the PE-2 strain, acid treatment significantly affected viability (%), budding (%), specific growth rate (μmax, h⁻¹) and change in absorbance. However, fermentative yield was not compromised by the acid treatment, suggesting an adaptive profile capable of sustaining fermentative capacity; in contrast, the CAT-1 strain showed greater sensitivity to acid stress, with effects on budding (%), alcohol content (g/100 mL) and sugar consumption (g/100 mL). The increase in budding occurred concomitantly with accumulation of residual sugars and reduction in yield, indicating a prioritization of survival and cell division at the expense of fermentative efficiency. Moreover, analysis of bud scars revealed evidence of selection for metabolically active cells accompanied by death of young cells, a behavior that did not vary markedly between strains or treatments. Taken together, these results indicate that, although the CAT-1 strain persists across cycles, it exhibits a lower fermentative yield than PE-2 in the presence of acid treatment, probably due to lower tolerance to the acid treatment and a stronger mobilization of growth strategies to maintain cell viability during fermentation.
Análise bibliométrica da produção científica brasileira sobre suicídio: um estudo nas bases de dados Scopus e OpenAlex
(Universidade Federal de São Carlos, 2025-10-30) Zanin, Alda de Cássia; Cangiani, Maria Laura Machado; http://lattes.cnpq.br/5263317427243364; https://orcid.org/0009-0001-8095-7835; Faria, Leandro Innocentini Lopes de; http://lattes.cnpq.br/0767710394930118; https://orcid.org/0000-0002-8369-1315; http://lattes.cnpq.br/4300995461915893
This research analyzed Brazilian scientific production on suicide, aiming to understand its academic approach and identify relevant trends, authors, institutions, journals, and thematic areas. To this end, a quantitative bibliometric research methodology was adopted, using bibliographic data from the Scopus and OpenAlex databases, processed by the VOSviewer and Biblioshiny tools to construct indicators of production, citation, and linkage. The results revealed significant growth in publications from 2010 onwards, especially between 2020 and 2021, with an emphasis on mental health, social vulnerability, and clinical-epidemiological studies. International cooperation is noteworthy, particularly with the United States, the United Kingdom, Portugal, and Canada. Among the most productive authors are Flávio Kapczinski, Neury Botega, Antonio Egídio Nardi, Maria Cecília Minayo, Karen Jansen, and Humberto Correa, and among the most frequently cited journals are Ciência e Saúde Coletiva, Revista Brasileira de Psiquiatria, and Jornal Brasileiro de Psiquiatria. The University of São Paulo leads the production, followed by other reference institutions, and the central areas of publication focus on Medicine, Psychology, Psychiatry, and Sociology, confirming the interdisciplinary nature of the topic. It was concluded that national research emphasizes mental disorders, vulnerable groups, social and environmental factors, epidemiological contexts, and manifestations of suicidal behavior, highlighting the relationship between psychological suffering, suicide risk, and impact on work. The study evidenced the need for responsible communication about suicide, grounded in scientific rigor and neutral language, in order to support health professionals, communicators, and managers in prevention and in strengthening support networks, such as the Center for Life Appreciation (CVV). Furthermore, it demonstrated the relevance of bibliometrics for Library and Information Science, by applying its tools to the analysis of a sensitive topic, and pointed to the importance of future qualitative research integrating mental health, communication, and information management, expanding support for the formulation of more effective public policies.
