Use of information and communication technology (ICT) by medical students
Authors: Pereira José Carlos Gomes , Santos Lucas Pontes dos , Caldas Cezar Augusto Muniz
Published: January 2023

Abstract: Introduction: The central topic of the present study is the evaluation of Information and Communication Technology use by medical students, since this relationship has become inseparable from medical training and practice. Objective: To characterize the profile of Information and Communication Technology use among medical students, identifying which are the most frequently used, the possible stimuli and the main impediments to its use. Method: An observational and cross-sectional study was carried out by applying an electronic form on the Google Forms® platform, to students attending from the 1st to the 12th semester of undergraduate medical school. Results: Of the 216 participants, there was a predominance of females (60.6%), aged between 20-24 years (65.3%) and with a family income of less than 3 minimum wages (36.1%). The main device used by the participants was the smartphone (68.1%) and the most frequently used Information and Communication Technologies were text messaging apps (99.5%) and internet browsers (96.8%), while Medication Apps (48.1%) and Specialized Calculators (31%) were significantly less often used. The main benefit mentioned was the possibility of distance communication, while the main impediment was the issue of security. Conclusion: It was concluded that the use of technologies by medical students is quite frequent and varied, but purposeful training, by teachers and students, is necessary for better use of the available technologies.
Escolarização, adolescência e a ubiquidade do entretenimento: práticas curriculares para o Ensino Médio no Brasil
Authors: Silva Roberto Rafael Dias da
Published: January 2023

RESUMO O presente estudo busca descrever os deslocamentos nas práticas curriculares direcionadas escolarização de adolescentes no sul do Brasil. Ao interrogar pela infraestrutura dessas práticas, foram descritos os propósitos formativos, as racionalidades orientadoras e as disposições formativas que reelaboram o conceito de aula. O corpus empírico que referenciou este estudo é constituído por um conjunto de oito entrevistas episódicas realizadas com professores e coordenadores pedagógicos que atuam no Ensino Médio. Em uma sociedade em permanente transformação, na qual as subjetividades destes estudantes e suas relações com a escola recebem um novo conjunto de investigações, os modelos de inovação educativa que são intensamente difundidos estão alicerçados em processos de estetização pedagógica. Neste contexto, pode-se concluir que as pedagogias emergentes para a escola dos adolescentes, especificamente no Ensino Médio, são regidas por duas racionalidades orientadoras: uma atrelada à gestão das aprendizagens na direção do desempenho em testes padronizados, outra sintonizada com estratégias criativas, interativas e divertidas com foco na ubiquidade do entretenimento.
Educação ambiental em Duque de Caxias, RJ: contradições entre o discurso hegemônico e as questões socioambientais do território
Authors: Floriano Marcio Douglas , Loureiro Carlos Frederico Bernardo
Published: January 2023

RESUMO O presente artigo discute a entrada de projetos de Educação Ambiental formulados por empresas em escolas públicas de Duque de Caxias, na Região Metropolitana do Rio de Janeiro. Ancorou-se teoricamente em pressupostos da Educação Ambiental Crítica e da Ecologia Política. Buscou-se apreender a lógica que norteia tais projetos e se eles colaboram para a precarização do trabalho docente e o enfraquecimento da autonomia da escola pública. Por outro lado, também constituiu objetivo verificar a relevância de tais projetos no enfrentamento das questões socioambientais do entorno das escolas. A opção metodológica foi a pesquisa qualitativa baseada na análise documental, na observação participante e em entrevistas com professoras de três escolas municipais da região. Nesse sentido, analisaram-se projetos de educação ambiental desenvolvidos nas unidades escolares por duas empresas situadas no Polo Petroquímico de Duque de Caxias (Reduc e Arlanxeo). Pode-se concluir que a entrada dessas empresas nas escolas acentua a precarização do trabalho docente e a expropriação dos conhecimentos das professoras, ao mesmo tempo em que fomenta uma postura conciliatória e pouco crítica dos alunos, se abstendo do enfrentamento das questões socioambientais que impactam nas condições de existência dos alunos e das comunidades da região.
Teacher insurgencies in the curriculum and the production of the thought of difference
Authors: Tedeschi Sirley Lizott , Pavan Ruth
Published: January 2023

ABSTRACT This paper aims to show that reflections/actions produced by teachers in their pedagogical practice contribute to the production of a kind of thought in the school curriculum that goes beyond the captivity of the representation. The analysis has stemmed from research conducted through semi-structured interview with teachers from a state public school. The analysis of the teachers’ statements is aligned with the post-structuralist perspective and shows how the reflections/actions produced by them give rise to/rise up a thought of difference in the curriculum, as they put us face to face with the limits of essentialism and universalisms of the representational thought.
Tendências na escolarização das elites paulistanas nos Séculos XX e XXI
Authors: Setton Maria da Graça Jacintho , Neves Paulo Rogério da Conceição
Published: January 2023

RESUMO O objetivo deste artigo é problematizar questões sobre a frequência no ensino básico de quatro gerações da elite paulistana dos século XX e XXI. Trata-se de análise dos dados recolhidos na pesquisa Pensamento e Práticas de Cultura da Elite Paulistana1. Com base em um questionário e entrevistas realizadas no período de 2018 a 2019, a intenção é analisar os motivos da escolha e as representações sobre as escolas. A hipótese principal apoia-se na teoria relacional dos grupos de Pierre Bourdieu, entre outras, e suas formas subjetivas e objetivas de construção de disposições de um habitus. Para desenvolver o argumento, faremos um exercício relacional entre tipos de instituições frequentadas pelos indivíduos pesquisados e seus filhos, lembrando as categorias de quadros, tempo, modalidades e disposições de cultura que se depreendem delas. Por intermédio de aspectos como a imagem dos estabelecimentos em sites institucionais, data de fundação, objetivos pedagógicos, filiações com projetos internacionais e religiosos, observamos de perto elementos de tais processos. Como resultados, sinalizamos que além de existir uma estreita correspondência entre as seleções escolares e os projetos familiares, sempre de acordo com o tempo de pertencimento às elites e os setores da economia, existiria uma tendência, desde o início do século passado, por escolas com vínculos no exterior.
(Re)lendo Bourdieu a partir da obra de Maria Helena Souza Patto
Authors: Viégas Lygia de Sousa , Costa Jackson Barbosa da , Machado Adriana Marcondes
Published: January 2023

RESUMO O presente artigo objetiva analisar as discussões dos conceitos elaborados por Pierre Bourdieu na obra de Maria Helena Souza Patto, professora aposentada e pesquisadora do Instituto de Psicologia da USP, cuja produção intelectual foi divisora de águas no campo da Psicologia em interface com a educação no Brasil. Do conjunto de escritos, será dado destaque a três livros e um capítulo: Psicologia e Ideologia (1984), A produção do fracasso escolar (1990), A miséria do mundo no terceiro mundo (2000) e A cidadania negada (2009). As referências a Bourdieu ao longo da obra de Patto dão relevo à necessidade de um diálogo crítico ao priorizar, em sua análise, a complexidade da realidade educacional brasileira e considerar os perigos na utilização de conceitos quando dissimulam as relações de forças presentes em suas articulações com as problemáticas estudadas.
Democratic limits of a common-to-all training project
Authors: Pereira Talita Vidal , Reis Matheus Saldanha do Amaral
Published: January 2023

ABSTRACT1 The writing of this text is mobilized by the discomfort caused by what is argued to be the “naturalization” of the idea of commonality present in curricular theories and policies. It is from this discomfort that it is proposed to reflect about the meanings of subject and, consequently, definitions of knowledge have been mobilized in curricular theories and policies? Assuming a deconstructive Derridean position, the democratic pretensions of discourses that project the formation of common identities filled by knowledge meant as universal is problematized. Arguments based on the contributions of Ernesto Laclau and Chantal Mouffe’s discourse theory are developed, in dialogue with the reflections produced by Jacques Derrida related to the philosopher’s critique of logocentrism. Without attempting to offer definitive truths, this text is an invitation to reflect on the need to destabilize norms and expose their limits, deconstructing the fragile pillars of structures that support the democratic pretensions of common formation projects. The bet is on the potential hyperpolitization of the social struggle that opens with the appropriation of theoretical contributions presented in this text.
Desafios simbólicos da universidade: a perspectiva de estudantes sobre a permanência
Authors: Mattos Hellen Cristina Xavier da Silva , Fernandes Maria Cristina da Silveira Galan
Published: January 2023

RESUMO Este artigo se insere nas discussões sobre a inclusão social nas universidades públicas, especificamente sobre a permanência universitária. Com as contribuições da teoria sociológica de Pierre Bourdieu, analisamos as percepções de estudantes sobre as suas experiências relacionadas à permanência universitária, aprofundando os mecanismos simbólicos presentes nos percursos estudantis em uma universidade pública federal. A metodologia empregada para a pesquisa utilizou questionários e entrevistas semiestruturadas com estudantes universitários, matriculados em diferentes períodos e cursos na graduação. Os resultados da investigação indicam que há o reconhecimento da relevância de auxílio financeiro para possibilitar a frequência no curso, porém os estudantes levantam desafios que são simbólicos e que interferem na permanência universitária. A dimensão simbólica está presente na responsabilização do aluno pelo seu desempenho, relacionado às dificuldades acadêmicas com o conteúdo cultural exigido e às práticas dos professores que pouco auxiliam os estudantes com maiores defasagens de capital cultural academicamente rentável. Consideramos que os dados oriundos das entrevistas, bem como as sugestões indicadas pelos estudantes para melhorar a permanência, revelam disputas presentes no campo universitário. Portanto, a presença de novos agentes possibilita alterações nas disputas do campo, o qual apresenta limites simbólicos para efetivar a proposta de inclusão social em uma instituição que tende à consagração das relações de força na sociedade.
Field, habitus and illusio - Pierre Bourdieu’s conceptual triad in the exercise of investigating the constitution of an academic subfield (media and technologies) in brazilian Physical Education
Authors: Mezzaroba Cristiano , Bassani Jaison José
Published: January 2023

ABSTRACT This article presents a research characterized as a historical sociology of the subfield of media and technologies (M&T) within the field of Brazilian Physical Education (PE), with the Bourdieusian concepts of field,habitusandillusio, seeking to inventory and analyze the constitution and consolidation of this movement in PE. Methodologically, it was configured as a qualitative research, of the case study type, seeking to understand this field and its conditions of possibilities. We presented and analyzed the interviews with nine agents of the aforementioned social space, who occupied/occupy structures of power within the subfield, coordinating the Communication and Media Thematic Working Group of the Brazilian School of Sport Sciences. It was possible to organize five interpretative axes, strongly related to the three concepts that epistemologically supported the research: (1) The subfield of M&T in the field of Brazilian PE: origin, conflicts, contemporaneity; (2) The social and academic legitimacy of PE; (3) Cultural formation and interdisciplinary aspects: thehabitusand the implications in the university and in school; (4) Cultural sociodynamics and implications in the university and school; (5) Affect as a disinterested interest: decodingillusio’s mechanisms. We conclude that every effort to capitalize on this “scientific game” carried out by the agents (as a network of sociability) is giving prominence to the subfield, as a strategy and collective effort to intensely pursue the objective of increasing the academic, scientific and social legitimacy of Brazilian PE, now with contributions from the social sciences and humanities.
The space of educational inequalities in São Paulo and Recife
Authors: Ferreira Daniela Maria , Perosa Graziela Serroni , Lebaron Frédéric
Published: January 2023

ABSTRACT This paper presents an empirical study on the social and educational gaps between Recife and São Paulo, cities characterized by fast urbanization and strongly unequal urban configurations. Based on the notion of social space and statistical data from the last Population Census (IBGE/ 2010), we present a study on the space of educational disparities in the two metropolises. The objective was to test the relevance of the notion of social space in the Brazilian context, identifying at once, the distribution of social groups and their educational investments. We argue that the notion of social space can integrate several other key concepts of Bourdieusian sociology. We mobilize a large set of variables captured simultaneously, bringing to light the differences within the two metropolises and between the cities. The study’s originality lies in starting from this wide range of objective indicators related to living conditions, associating it with the use of indicators likely to be perceived as “subjective.” As expected, the first axis strongly correlates with longevity, household income, and education level. The second axis is the result of the correlation between the possession of a high school diploma and the presence of greater public infrastructure. In Recife, this second axis concerns a few neighborhoods in the city. In São Paulo, however, the same correlation is observed with a much larger set of neighborhoods in intermediate social positions. It is also noticeable that Recife has a much larger number of regions in extreme poverty compared to São Paulo.
Knowledge and Subjects of Environmental Education: historicizing formative experiences at the Itatiaia National Park (1937-2020)
Authors: Toledo-Quiroga Kemily , Ferreira Marcia Serra
Published: January 2023

ABSTRACT The aim of this work is to historicize the way in which the Itatiaia National Park (PNI) has signified knowledge of Environmental Education (EE) and, simultaneously, constituted subjects that “must” educate and be environmentally educated. It was produced by the Curriculum History Study Group, a research collective at the Nucleus of Curriculum Studies at the Federal University of Rio de Janeiro (NEC/UFRJ), articulating investigations interested in operating with Curriculum History as History of the Present. The PNI was selected because it was the first space that was designated as a National Park in Brazil, creating a visitation “model” that articulates, through alchemical processes, the EE knowledge that is to be taught and the different subjects for whom this knowledge is intended. In dialogue with Michel Foucault and Thomas Popkewitz, we focus on the historical constitution of the visiting subjects for whom the park’s formative actions were taken. We then show how the EE knowledge produced through these actions came to be alchemically transformed in the midst of a logic that has historically constituted what we call “school”, in close dialogue with the processes of disciplinarization that have organized the time and space of this institution. In this process, we highlight how the boundaries between the two institutions have been “blurred”, allowing us to establish an in-between place of subjects/visitors/students amid disciplined EE knowledge.
Bourdieu e o Brasil: esboço de uma genealogia acadêmica
Authors: Silva Camila Ferreira da , Oliveira Amurabi
Published: January 2023

RESUMO A difusão e apropriação do pensamento de Pierre Bourdieu no Brasil tem se consolidado como objeto de estudo nas duas últimas décadas no interior das Ciências Sociais. O presente artigo junta-se, pois, a esta frente de análise, com o escopo circunscrito aos pesquisadores brasileiros que atuaram como divulgadores das ideias e das obras de Bourdieu entre as décadas de 1960 e 1990, a partir de contato direto e indireto com o sociólogo francês. Com o objetivo de compreender o papel desses então jovens investigadores na difusão do pensamento bourdieusianos no Brasil, construímos um esboço da genealogia acadêmica de Bourdieu no Brasil a partir de dados extraídos das plataformas Lattes e Acácia, de entrevistas e relatos de experiências publicados no Centro de Pesquisa e Documentação de História Contemporânea do Brasil (CPDOC) e em periódicos científicos, bem como de contato direto com os sujeitos mapeados. Os resultados apontam para a existência de uma divulgação científica que ocorreu não apenas através da tradução de trabalhos originais de Bourdieu para o português e da publicação de artigos e coletâneas sobre sua obra, como também através da circulação de suas ideias por meio de cursos, palestras e orientações, de modo que esses interlocutores assumiram uma posição central na consolidação deste autor no campo acadêmico brasileiro.
Assessment certification of young people and adults, experience and knowledge in the field of science: notes for curriculum and assessment policies
Authors: Santos André Vitor Fernandes dos , Marsico Juliana , Oliveira Cecília Santos de
Published: January 2023

ABSTRACT The verification and subsequent certification of knowledge developed by youths and adults has historically been done through supplementary examinations and, since the early 2000s, through the National Examination for the Certification of Youth and Adult Skills (Encceja). We present here a reflection on how knowledge related to the school subject of Science is addressed in this examination. Our concern is over the relationship between knowledge and experience and the role that language plays in the expression of this knowledge. Our interest lies in conducting an exercise, considering the context of the circulation of the National Common Curricular Base (BNCC) to visualize how the discourses that comprise these documents allow us to question the place of the specific characteristics of the subjects of Youth and Adult Education (YAE) in the production of what counts as knowledge.
La constitución del subcampo de la formación de profesores de química y las estrategias de subversión para su reconocimiento en el ámbito científico de la Química
Authors: Silva Francisca das Chagas Alves da , Mesquita Nyuara Araújo da Silva
Published: January 2023

RESUMEN Considerando la lectura analítica a partir de la teoría de los campos formulada por Pierre Bourdieu, centrada en el área de la Enseñanza de la Química y la estructuración del subcampo de la formación de profesores de química (FPQ), en el presente texto abordamos el campo como espacio social desde el punto de vista del campo científico de la química (CCQ), el habitus de los agentes, las posiciones, las disputas, los intereses y las estrategias de subversión establecidas por el subcampo de la FPQ para buscar su espacio en la química. Argumentamos sobre estas diferentes configuraciones desde el punto de vista del subcampo de la FPQ, dominado en el campo de la química, analizando la producción científica en el área de la Enseñanza de la Química y los datos de las plataformas Acácia y Sucupira. En este proceso utilizamos la metodología praxeológica de Bourdieu y su análisis relacional para debatir las estrategias desarrolladas por los agentes del subcampo de la FPQ en el CCQ para configurar su propio capital y establecer un movimiento de reconocimiento del habitus distinto al del propio químico. Entre dichas estrategias destacan la organización de eventos científicos, la producción de revistas en el área de la Enseñanza de la Química, la formación de maestros y doctores en programas de posgrado en los que los agentes buscan la constitución de un capital científico y el espacio para el reconocimiento del subcampo como perteneciente al campo de la química.
The ethical responsibility of answering what purpose school serves
Authors: Santos Maria , Macedo Elizabeth
Published: January 2023

ABSTRACT We were urged to this discussion by the “persecution” suffered by the school during the COVID-19 pandemic, a persecution to which it is our ethical-political duty to respond. This is an essay that intends to problematize the serving of the school - which seems to confer its meanings - to defend that such meanings only appear in the relationship with the other that defines them and that also distort our own subjectivation. The school, as a name, only exists because it integrates the whole lived experience with the world and with ourselves and, therefore, cannot be defined a priori or by a serving. In the construction of this text, we were haunted by conversations triggered by the interpellation “What purpose does school serve?” with teachers and administrative agents of the municipal education network in the city of Niterói, Rio de Janeiro, Brazil. From a theoretical point of view, we have a dialogue mainly with Judith Butler, Janet Miller and Gert Biesta to defend that a responsible or responsive pedagogical theory needs to make any ideal of school come accompanied by its deconstruction.
Mas, afinal, que sujeito é esse? Dilemas ético-políticos, concepções de democracia e os sujeitos da aprendizagem na BNCC do Ensino Médio
Authors: Silva Daniel Pinha , Gonçalves Marcia de Almeida
Published: January 2023

RESUMO O artigo examina as relações entre os sujeitos da aprendizagem, tanto o estudante quanto o/a professor/a, e a mobilização do conceito de democracia na Base Nacional Comum Curricular (BNCC) correspondente à etapa do Ensino Médio, com destaque para a área de Ciências Humanas e Sociais Aplicadas na versão final de 2018. A partir das circunstâncias históricas de produção dessa versão final da BNCC e da delimitação teórica dos dilemas que afetam as subjetividades contemporâneas, é analisado o modo pelo qual o conceito de democracia figura no texto da base curricular mencionada. Constata-se que a democracia é situada como regulador das aspirações ético-políticas de estudantes, sob o viés, no entanto, de horizonte de estabilidade política, desprovida de historicidade, esvaziando assim a agência e o enfrentamento da crise contemporânea pelos sujeitos da aprendizagem.
But anyway, who is this subject? Ethical-political dilemmas, conceptions of democracy and the subjects of learning in the BNCC for High School
Authors: Silva Daniel Pinha , Gonçalves Marcia de Almeida
Published: January 2023

ABSTRACT The article examines the relationships between the subjects of learning, both the student and the teacher, and the mobilization of the concept of democracy, in the National Common Curricular Base, stage of High School, highlighting the area of Applied Human and Social Sciences, final version of 2018. The way in which the concept of democracy appears in the current curriculum base text is analyzed, based on the historical circumstances of the production of this final version of this curriculum and, also, based on the theoretical delimitation of the dilemmas that affect contemporary subjectivities. The main conclusion is that democracy is situated as a regulator of the ethical-political aspirations of students, under the bias, however, of a horizon of political stability, devoid of historicity, thus emptying the agency and the confrontation of the contemporary crisis by the subjects of learning.
Domenico Caon e o amor pela obra A Divina Comédia
Authors: Rela Eliana , Bernardi Manuela Ciconetto
Published: January 2023

RESUMO Este trabalho objetiva discutir a vida de Domenico Caon, imigrante italiano que viveu no Rio Grande do Sul, procurando compreender a intensa relação que ele, enquanto leitor, desenvolveu com a obra A Divina Comédia, de Dante Alighieri. Domenico Caon nasceu em 1876 na província de Pádua, Itália, e imigrou ao Brasil ainda jovem com a família, fixando residência com a esposa e os filhos onde hoje se localiza o município de Nova Roma do Sul. Domenico atuou, entre outras atividades, como político, comerciante, artesão e agricultor. Este estudo foi concebido a partir de evidências de práticas de leitura desenvolvidas pelo imigrante que merecem uma atenção detalhada, principalmente no sentido de explicar como surgiu o seu gosto pela leitura e como Domenico relacionou sua experiência de leitura com o social e o seu entorno. Os procedimentos teórico-metodológicos empregados nesta análise são fundamentados na História Cultural e da História da Educação; em especial, usa-se o conceito de práticas de leitura proposto por Batista e Galvão (2002). No decorrer deste texto, apresentam-se informações oriundas de pesquisa genealógica do imigrante, e indícios de como a leitura, em especial da obra A Divina Comédia, esteve presente em sua trajetória pessoal. Da investigação, conclui-se que práticas de leitura desenvolvidas por atores sociais, como as de Domenico, permitem abrir possibilidades investigativas e examinar as singularidades que envolvem os processos históricos de alfabetização fora do ambiente escolar.
Presentation: Reflexivity and denunciation: Pierre Bourdieu and research in education, two decades on
Authors: Valle Ione Ribeiro , Knoblauch Adriane
Published: January 2023

ABSTRACT In 2022 we remember the 20th anniversary of the death of Pierre Bourdieu, an important sociologist who, over the decades, developed an extensive work that covered various themes and defined important concepts for the development of his research, such as the notions of habitus, field, and capital. The interweaving of these notions allowed the weaving of quite original analyses. Specifically on education, his writings, which mark his reflexivity and his spirit of denunciation, allow us to better understand the relations between social, cultural, and school inequalities. In this issue, we present ten articles from different regions of the country, covering quantitative and qualitative research and a rich thematic diversity. They are researches that mobilized the author’s modus operandi, demonstrating that Pierre Bourdieu continues to be an unavoidable reference for research in education.
Apresentação - Docência: entre processos de objetivação e subjetivação de sujeitos e conhecimentos
Authors: Gabriel Carmen Teresa , Martins Marcus Leonardo Bomfim
Published: January 2023

RESUMO A questão da docência constitui-se como temática clássica nos estudos do campo educacional. Ela envolve dimensões políticas, éticas, epistemológicas e ontológicas que se movimentam em direções e sentidos que dependem da perspectiva armada para ver. Argumentamos neste texto que o sentido de docência no qual interessa-nos investir é produzido em meio a processos de objetivação e subjetivação de sujeitos e conhecimentos. A partir de uma postura epistêmica pós-fundacional (MARCHART, 2009; LACLAU, 2005, 2011) que radicaliza a crítica aos subjetivismos transcendentais e aos objetivismos deterministas na interpretação do Social, optamos por construir nossas argumentações a partir de eixos que, em nosso entender, consistem em aporias que permitem, simultaneamente, compreender, problematizar e participar do processo de significação da docência. Universal/particular, subjetividade/objetividade, teoria/prática, ensino/aprendizagem, ciência/pedagogia e escola/universidade foram os eixos selecionados para participar do referido processo.
Presentation - Teaching: between processes of objectification and subjectivation of subjects and knowledge
Authors: Gabriel Carmen Teresa , Martins Marcus Leonardo Bomfim
Published: January 2023

ABSTRACT The issue of teaching constitutes a classic theme in studies in the educational field. It involves political, ethical, epistemological and ontological dimensions that move in directions and meanings that depend on an armed perspective to see. We argue in this text that the meaning of teaching in which we are interested in investing is produced in the midst of processes of objectification and subjectivation of subjects and knowledge. From a post-foundational epistemic posture (MARCHART, 2009; LACLAU, 2005, 2011) that radicalizes the critique of transcendental subjectivisms and deterministic objectivisms in the interpretation of the Social, we chose to build our arguments from axes that, in our view, consist of aporias that allow, simultaneously, to understand, problematize and participate in the process of meaning of teaching. Universal/particular, subjectivity/objectivity, theory/practice, teaching/learning, science/pedagogy and school/university were the axes selected to participate in this process.
Os professores e sua formação profissional: entrevista com António Nóvoa
Authors: Lomba Maria Lúcia Resende , Faria Filho Luciano Mendes
Published: January 2023

RESUMO Para António Nóvoa, há muitas maneiras de ser professor, uma diversidade de opções e de caminhos. Contudo, em todos eles, defende que é imprescindível compreender a complexidade da profissão em todas as suas dimensões: teóricas, experienciais, culturais, políticas, ideológicas e simbólicas. Trata-se de um conhecimento profissional docente, um conhecimento contingente, coletivo e público. E é com base nesse conhecimento que ele afirma que se devem organizar novos modelos de formação docente: uma formação que garanta aos professores espaços e tempos para o desenvolvimento do autoconhecimento e da autorreflexão sobre as dimensões pessoais, profissionais e coletivas do professorado.
Dentoalveolar changes observed after the use of customized bonded Shark-Tooth-Like Spurs (JAWs) in adult patients with anterior open bite
Authors: KRAISIRIDEJ Rungrawee , SUZUKI Boonsiva , SUZUKI Eduardo Yugo
Published: January 2023

ABSTRACT Introduction: Tongue spurs have been successfully used for the early treatment of anterior open bite (AOB). However, according to our knowledge, their effectiveness in the treatment of adults has not been evaluated. Objectives: The purpose of the study was to assess the dentoalveolar changes observed after the use of customized bonded shark-tooth-like spurs (JAWs) in adults with AOB. Methods: Twenty-three adults (22.1±4.4 years) with AOB were selected for the treatment. JAWs made from compomer cement were bonded on the lingual surfaces of the maxillary and mandibular anterior teeth to correct tongue-thrusting. Lateral cephalograms and 3D digital models were obtained to evaluate dentoalveolar features observed before and at three time points after JAWs use. Paired t-test and repeated measure ANOVA tests were used to compare dentoalveolar changes, and Pearson’s correlation was used to analyze the association of dentoalveolar changes and overbite changes. The significance level was set at p<0.05. Results: Significant 3D dentoalveolar changes were observed after the three months of treatment with JAWs. Improvement of overbite (1.0±0.6 mm) and overjet (0.2±0.3 mm), combined with a retroclination of maxillary (3.0±3.0°) and mandibular (2.2±2.7°) incisors, were observed (p<0.05). Moreover, a significant decrease in anterior dental arch width in both maxillary and mandibular arches (0.4±0.4 mm; 0.3±0.3 mm, respectively), and an increase of posterior maxillary (0.1±0.2 mm) dental arch width were observed (p<0.05). These significant changes occurred in the first month after the JAWs use. A significant correlation was found between the initial arch length discrepancy and the amount of overbite correction (r=0.456, p<0.05). Conclusions: Dentoalveolar changes occurred after the first-month therapy with JAWs. The retroclination of the anterior teeth combined with the expansion of posterior teeth suggests a posterosuperior change in the tongue position. These changes were beneficial for the treatment of AOB in adult patients.
COM E PARA ALÉM DE BOURDIEU: REVISITANDO DUAS TESES CENTRAIS
Authors: Nogueira Maria Alice , Resende Tânia de Freitas
Published: January 2023

RESUMO Ao se registrar o vigésimo aniversário de morte do sociólogo francês Pierre Bourdieu, este texto discute dois aspectos de sua obra que representaram forte avanço no conhecimento, mas demandam uma atualização no que concerne ao mundo social da educação, em vista de suas transformações nas últimas décadas. São eles: as teses sobre a relação entre a posse de capital cultural e o sucesso escolar, em particular a hipótese de uma transmissão osmótica — de pais a filhos — dessa forma de vantagem social; a tese da causalidade do provável desenvolvida por meio da noção de interiorização das chances objetivas, como hipótese para se compreender como cada indivíduo constrói suas aspirações e formula seus projetos.

Authors: Castro Estefani Santos , Bacil Leticia Furman , Almeida Franciny de Lima de , Andreazza Marimar Goretti , Alves Rodolfo Augusto , Valderramas Silvia Regina
Published: January 2023

Abstract Introduction Multiple studies have shown the effects of prone (PP), supine (SP) and kangaroo (KP) positions on clinical and physiological outcomes in preterm newborns, but none compared these three types of positioning between them. Objective To investigate the influence of these positionings on heart rate, respiratory rate, peripheral oxygen saturation (SpO2) and alertness status in clinically stable preterm newborns (NBs) admitted to a neonatal intensive care unit. Methods In a randomized clinical trial, clinically stable NBs with gestational ages from 30 to 37 weeks who were breathing spontaneously were allocated in three positioning groups: PP, SP and KP. Heart rate, breathing frequency, SpO2 and alertness status were evaluated immediately before and after 30 minutes of positioning. Results In all, 66 NBs were assessed (corrected age: 35.48 ± 1.94 weeks; weight: 1840.14 ± 361.09 g), (PP: n = 22; SP: n = 23; KP: n = 21). NBs in the PP group showed a significant improvement in peripheral SpO2 (97.18 ± 2.16 vs 95.47 ± 2.93 vs 95.57 ± 2.95, p = 0.03) compared with the SP and KP groups. Conclusion In clinically stable preterm NBs, the PP was associated with better peripheral oxygen saturation than the SP or KP. In addition, there was a reduction in heart rate within prone position group and in the KP group there was an increase in the number of NBs in the deep sleep classification.
Okra salt stress reduction under potassium fertigation

Published: January 2023

ABSTRACT Potassium fertigation may be a strategy to reduce saline stress in okra. The objective of this study was to analyze the effect of potassium supplementation as a salinity-attenuating agent in okra. The experiment was conducted in a greenhouse at the Federal Rural University of the Semi-Arid Region, in Mossoró-RN, Brazil. The experimental design was completely randomized, in 2x5 factorial scheme with 4 replicates. Two okra cultivars (Santa Cruz 47 and Valença) fertigated with five fertigation managements [F1= irrigation with non-saline water (0.55 dS/m) and fertigation with a standard dose of potassium (6 g/plant); F2= irrigation with saline water (3.5 dS/m) and fertigation with 6 g/plant of K, F3= irrigation with saline water (3.5 dS/m) and fertigation with 9 g/plant of K, F4= irrigation with saline water (3.5 dS/m) and fertigation with 12 g/plant of K, and F5= irrigation with saline water (3.5 dS/m) and fertigation with 15 g/plant of K]. Plants were collected 110 days after emergence and evaluated for growth variables (leaf number, leaf area, leaf dry mass, stem dry mass, total dry mass) and yield (fruit number, average fruit mass and fruit production). Potassium influenced the growth and yield characteristics of okra irrigated with saline water. The highest yields of fruits occurred at 9.56 and 10.23 g/plant of K, being 330.24 and 733.36 g/plant obtained from cultivars Santa Cruz 47 and Valença, respectively. Okra irrigated with saline water is more demanding in potassium.

ABSTRACT Calcium and boron are important nutrients in pollen grain formation and seed production. As they are little mobile in plants, it is common to be supplied via foliar application. The objective of this research was to evaluate the production and quality of sweet pepper seeds with calcium and boron application directed to flowers and fruits. The experimental design was in randomized blocks, with seven replications. Four treatments were evaluated: isolated calcium (0.2%) application, isolated boron (0.1%) application, combined application of calcium (0.2%) and boron (0.1%), and the control without calcium and without boron. The characteristics evaluated were number of pollen grains, number of seeds per fruit; 1000 seed weight; physiological quality of seeds (germination, first germination count, and germination speed index) and protein (albumin, globulin, prolamine and glutelin) contents in seeds. Both the application of calcium and boron did not affect the physiological quality of the seeds. Boron application reduced seed production and the 1000 seed weight, while calcium application increased the number of pollen grains, seed production and seed albumin content, and, therefore, the application of calcium in the production of sweet pepper seeds is recommended.

ABSTRACT The populations of Melocactus zehntneri 'chapéu-de-frade' have shown an alarming decline due to the constant withdrawal of individuals from their natural areas. The low percentage of germination of M. zehntneri seeds, added to the slow growth, requires a system for commercial propagation of this species. This study aimed to test the influence of water, hydrochloric acid or acetic acid pre-treatments on seed germination and the influence of different substrates on the initial development of M. zehntneri seedlings. The seeds were immersed in deionized water, hydrochloric acid (5N) or glacial acetic acid (100%) for 10, 20, 30, 40 and 50 minutes and placed to germinate in a Petri dish containing filter paper moistened with 5 mL deionized water. The seedlings obtained from this germination (≡ 0.4 cm diameter) were cultivated on Carolina Soil® and vermiculite [2:1] substrates; Carolina Soil® and vermiculite [2:1] + drainage; medium-grained sand; medium-grained sand + drainage; medium-grained sand and organic compost [1:1]; medium-grained sand and organic compost [1:1] + drainage; and Carolina Soil® and medium-grained sand [1:1]. The highest percentage of germination was obtained with the pre-treatment by immersion in water, in the times of 10 and 30 minutes, totaling 55% of germinated seeds. Treatments with hydrochloric acid did not increase the percentage of germinated seeds, which were also close to 50%. In the test with the substrates, in Carolina Soil® there were the best rates of seedling survival after transplanting (87.5%) and seedling development performance. Treatments containing organic compost resulted in lower survival (69%) and seedling development. Seed germination and seedling development in Carolina Soil® substrate and sand proved to be an excellent alternative for the production of M. zehntneri seedlings.

ABSTRACT The use of organomineral fertilizers (OF) in the cultivation of vegetables has been considered a promising technology to provide nutrients gradually. The OFs can reduce the phosphorous (P) soil adsorption and leaching of nitrogen and potassium with the supply of some micronutrients. This study aimed to evaluate doses of OF as a source of P and micronutrients (boron and zinc) for curly lettuce cultivation. Five OF doses were evaluated: T1 = 0% (no P2O5 fertilization); T2 = 50% (75 mg/dm3 of P2O5); T3 = 100% (150 mg/dm3 of P2O5); T4 = 150% (225 mg/dm3 of P2O5); T5 = 200% (300 mg/dm3 of P2O5) of the lettuce recommended fertilization; T6 = 100% mineral fertilizer (MF) (150 mg/dm3 of P2O5). The fresh (FM) and dry mass (DM) of the lettuce shoot (aerial part), the soil nutrient level, and the plant nutritional status at harvest were evaluated. We observed that (i) the doses of 225 and 300 mg/dm3 of P2O5 via OF provided the same availability of P in the soil as the dose of 150 mg/dm3 of P2O5 of MF; (ii) the doses of 225 and 300 mg/dm3 of P2O5 of OF provided higher levels of soil boron and zinc compared to other treatments and (iii) the MF fertilization was more efficient than that of OF in the production of curly lettuce in a protected environment.

ABSTRACT Chili peppers are among the most important vegetables in the world. The demand of this fruit reveals a noticeable rapid increasing, which importance is mainly due to its nutraceutical composition. These fruits are rich in capsaicinoids, phenolic compounds, carotenoids, and others, including vitamins. In this study, a comparative evaluation between two extraction methods of bioactive compounds of fourteen chili pepper cultivars was performed. Two extraction methods for antioxidants, the time-solvent and the ultrasound were evaluated. The design of the experiment was completely randomized with three repetitions where variables evaluated were total phenolic compounds, flavonoids content, antioxidant capacity and capsaicin. Results showed that the phenolic compounds oscillated between 48.7 - 634.1 mg GAE/100 g dry weight (DW), the flavonoids content varied from 1 - 97 mg QE/100 g DW, the antioxidant activity from 65 - 348 µmol Trolox/g DW and the capsaicin content oscillated from 0.3 - 922 mg/100 g DW. The extraction method with higher values of bioactive compounds for each of the chili pepper types was the ultrasound for all the measured variables.

ABSTRACT The aim of this study was to evaluate, in three consecutive cycles, the phytotechnical performance of herbaceous fabaceous plants cultivated in monocropping or intercropped with corn and the pumpkin productivity in succession. The statistical design was of randomized blocks in a factorial arrangement 2 (monocropping or intercropping) x 3 (fabaceous species) + 1 (corn monocropping). The treatments consisted of gray velvet bean monocropping; gray velvet bean intercropped with corn; sunn hemp monocropping; sunn hemp intercropped with corn; jack bean monocropping; jack bean intercropped with corn and corn monocropping. After cutting the fabaceous and corn, Itapuã 301 pumpkin cultivar was planted. The authors verified that fabaceous monocropping reached higher dry biomass productivities, especially sunn hemp in the first and second years and provided greater accumulation of N, P and K. In the first year, fabaceous pre-cropping, regardless of the arrangement, provided an increase in pumpkin productivity up to 165.87% higher comparing with corn pre-cropping, whereas in the second and third years, no pumpkin production associated with corn monocropping was observed. The three Fabaceae species showed potential to be used as green manure in pumpkin growing when compared with corn pre-cropping.

ABSTRACT In the world the consumption of strawberries is very appreciated, both in natura or industrialized form. Brazilian production depends on the importation of strawberry seedlings from countries such as Spain, Chile and Argentina, which are cultivars improved in temperate climates and, consequently, not well adapted to the Brazilian tropical conditions. Thus, genetic breeding programs are essential for the generation of more adapted cultivars. The objective was to evaluate and characterize the performance of experimental strawberry genotypes. The statistical design adopted was in randomized blocks, with 12 treatments and 3 replications, the treatments consisting of seven experimental genotypes and five commercial cultivars. We evaluated the total production per plant (g/plant), average weight of fruits per plant (g/fruit), % of commercial fruits per plant, and morphological characterization. The experimental genotypes MFA443, MCA94, MDA23, MDA06 and MCA89 showed the highest strawberry yields per plant, respectively, 285 g, 254 g, 298 g, 295 g and 290 g, with emphasis on the genotype MFA12-443, which also presented the highest average weight of fruits (20.35 g) and percentage of commercial fruits (81%).

ABSTRACT The cultivation of vascular plants in aquaculture is becoming increasingly important and saline aquaponics have been centered on plants with a short life cycle (i.e. annual species). However, the cultivation of perennial halophytes can allow to produce biomass year-round by repeated cuttings and regrowth. The present study evaluated the effects of different cutting regimes on the growth and tissue nitrogen uptake of the perennial halophyte Paspalum vaginatum and Salicornia neei cultivated in saline aquaponics. Clarified water from Litopenaeus vannamei cultivation was used as the main source of water and nutrients to grow plants established in Nutrient Film Technique (NFT). In each trial (28 days), three groups of 22 plants were established in different NFT benches and subjected to no cutting, one harvest and two harvests. Cutting regimes applied to both halophytic species did not affect the quality of recirculating water. Tillering and stem elongation of P. vaginatum had increasing trends with augment of cutting frequency. Salicornia neei cut at 28-day intervals produced a larger number of marketable size branches with less lignified shoots than non-cut plants and branchy plants cut every 14 days, which showed the smallest branch size. Individual plants of P. vaginatum and S. neei took up in their tissues between 2.27-2.45 mg/day of N and 4.59-6.43 mg/day of N, respectively. Cutting regimes did not statistically affect the accumulation of nitrogen in the biomass of either halophytic species. One harvest treatment, every 28 days, was considered the most suitable practice for aquaponics production of both halophytes.
