    Esta pesquisa tem como objetivo compreender as experiências e os sentidos atribuídos pelas mulheres para se tornarem cuidadoras de idosos dependentes, à luz da análise da socialização de gênero. Estudo qualitativo com 53 cuidadorasfamiliares, realizado de junho a setembro de 2019, nas cidades de Belo Horizonte, Rio de Janeiro, Porto Alegre, Araranguá, Manaus, Fortaleza e Teresina. A análise das informações guiou-se pelo referencial teórico-metodológico da hermenêutica-dialética. Os achados foram organizados em quatro categorias: a função cuidadora como algo “natural” da mulher; homens ausentes no ato de cuidar e a manutenção da masculinidade; a responsabilidade marital de esposas e a identidade de gênero para o cuidar; a economia e o cisheteropatriarcado como norteadores para assumir o cuidado. As mulheres exercem o cuidado em decorrência da socialização de gênero. Esse fato é potencializado pelas circunstâncias de estarem solteiras, residirem com a pessoa idosa, ausência masculina na partilha do cuidado, responsabilidade marital e pressão para se retirarem do mercado de trabalho. Em conclusão, o modelo de cuidado centrado na família é sustentado pelas mulheres devido as dinâmicas sociais construídas em uma sociedade capitalista e centrada no cisheteropatriarcado. Isto sinaliza para a necessidade de a sociedade intervir, refletir e propor ações para um cuidado equilibrado entre homens e mulheres.This research aimed to understand the experiencesand meanings attributed by women to become caregivers of dependent older adults, in the light of the analysis of gender socialization. Qualitative study with 53 family caregivers, carried out from June to September 2019, in the cities of Belo Horizonte, Rio de Janeiro, Porto Alegre, Araranguá, Manaus, Fortaleza, and Teresina. The analysis of the information was guided by the theoretical-methodological framework of hermeneutics-dialectics. The findings were organized into four categories: the caregiver role as something “natural” for women; men absent from the act of caring and maintenance of masculinity; the marital responsibility of wives and gender identity to care; and the economy and cisheteropatriarchy as guides to take up the care. Women exercise care due to gender socialization. This fact is enhanced by the circumstances of being single, living with the older adults, male absence from sharing care, marital responsibility, and pressure to withdraw from the job market. In conclusion, the family-centered care model is sustained by women, due to the social dynamics built in a capitalist, cisheteropatriarchal-centered society. This signals the need for society to intervene, reflect, and propose actions for balanced care between men and women

    Unraveling the thread of painting: an essay by Mário Cesariny

    Recentemente, a crítica passou a dedicar maior atenção aos ensaios de Mário Cesariny. As análises empreendidas com frequência tomam como ponto de partida apenas as produções textuais do poeta, que, no entanto, passou a ser reconhecido, primeiro, por seu trabalho visual. Este artigo propôs, na contramão do caminho que parece estar sendo percorrido, uma espécie de provocação: ler um quadro como um ensaio.Critics have recently begun to devote greater attention to Mário Cesariny’s essays. The analyses undertaken often take as a starting point only the poet’s textual productions, although he came to be recognized, first, for his visual work. This article aimed to pursue a different path from what seems to be undertaken more frequently; a kind of provocation: reading a painting as an essay.info:eu-repo/semantics/publishedVersio

    Objective: To evaluate the effects of unilateral loss of the lower first permanent molar (L6) on the position and development of the lower third molar (L8). Material and Methods: Fifty-four panoramic radiographs of subjects with unilateral loss of L6 were examined. The L8 on the side of the L6 loss was compared with the L8 in the hemiarch without L6 loss (contralateral). The effect of L6 loss on the positioning of L8 was examined in all the samples (n=54), whereas the effect on the development of the third molar was examined in 38 patients with L8 with incomplete root formation. The Signs statistical test was used to evaluate the comparison between loss and contralateral hemiarches. Results: In 20 (37%) of 54 subjects, the L8 was better positioned in the hemiarch with loss of the lower first molar (p<0.001) compared with the control side. In the remaining 34 subjects, no difference was found. When only the L8 considered as impacted on the control side was examined (n=30), the cases with better positioning on the side with L6 loss increased to 66.6% (p<0.001). Conclusion: The loss of lower first molars improves the position of the lower third molar during its active eruption, mainly when the lower third molar is impacted. However, L6 loss does not affect the root development of lower third molars

    The academic illiteracy of newcomers to Higher Education Institutions has been a limiting factor for completing the course stronger than financial and other aspects. In this study, the reading ability, text interpretation and textual production of students entering a Federal Institution of Higher Education IFES in the State of Maranhão were verified, and mitigating measures were implemented that encourage interpretive reading and textual production. The activities were developed in two stages: (I reading and textual interpretation; II textual production) and all were applied online through the Google Classroom platform. Adherence to the project was low and most of the class was composed of students of Degree in Biology. Continued reading in stage I positively affected textual production in stage II. The performance of students in stage II was superior to that of stage I. Newly graduated high school students, who participate in research projects, teaching projects, scientific initiation scholarship holders and from private schools showed the highest levels of performance in reading, interpretation of texts and textual production.O iletramento acadêmico de ingressantes das Instituições de Ensino Superior e tem sido um  limitante à conclusão do curso mais forte do que aspectos financeiros e de outra natureza. Nesse estudo, verificou-se a capacidade de leitura, de interpretação de texto e de produção textual de estudantes ingressantes em uma Instituição Federal de Ensino Superior IFES do Estado do Maranhão, e implementou-se medidas mitigadoras que fomententram a leitura interpretativa e a produção textual. As atividades foram desenvolvidas em duas etapas: (I leitura e intepretação textual; II produção textual) e foram todas aplicadas online através da plataforma Google Classroom. A adesão ao projeto foi baixa  e a maior parte da turma foi composta por estudantes do curso de Licenciatura em Biologia. A leitura continuada na etapa I afetou positivamente a produção textual da etapa II. O desempenho dos estudantes na etapa II foi maior do que na etapa I. Os estudantes recém egressos do ensino médio, que participam de projetos de pesquisa, de projetos de ensino, que são bolsistas de iniciação científica e que são oriundos de escolas privadas, apresentaram os níveis mais altos de desempenho em leitura, interpretação de textos e produção textual
