IMPACTO DE VARIÁVEIS CONGNITIVAS E CONTEXTUAIS SOBRE O SUCESSO ACADÊMICO E O BEM ESTAR NA UNIVERSIDADE – QUE FAZER? QUE DEIXAR DE FAZER?

Este estudo parte de uma investigação longitudinal (2019-2022) mais ampla, vinculada ao Grupo Multidisciplinar de Pesquisa em Educação, Psicopedagogia e Psicologia Escolar, UFAM/CNPq, PROCAD/AMAZÔNIA-PPGEUFAM/UFPA/UFMT, Processo CAPES 8881.314288/2019-0, articula-se metodológica e teoricamente com interfaces entre a psicologia escolar, psicologia educacional, pedagogia do ensino superior e educação escolar. Atua no sentido de entender os efeitos de variáveis cognitivas e contextuais sobre o sucesso acadêmico e o bem estar na universidade. A metodologia para coleta de dados é a aplicação de caderno de instrumentos próprios com apoio do Googleodocs, a amostra atual é de n=1112 estudantes de diferentes países (Brasil, México, República Dominicana, Bolívia, Moçambique, Angola, Venezuela, Colômbia, Espanha e Portugal), do sexo masculino e feminino, idade entre 18 e 54 anos e de 51 universidades públicas e privadas que colaboram com a iniciativa. Os dados são analisados com auxílio do Excel e SPSS, de acordo com os interesses dos pesquisadores e objetivos da investigação. Os resultados atuais demonstram a importância da pesquisa sobre os temas abordados pela iniciativa considerando o impacto das variáveis estudadas sobre o rendimento acadêmico e bom estar tanto de estudantes como de docentes e técnicos no ensino superior. Foram identificadas diferenças de países, renda, etnia, gênero e renda. No caso dos docentes e técnicos verificamos evidências da exaustão feminina. Os resultados podem apoiar a administração geral e coordenação educativa e psicopedagógica universitária em sentido amplo, visando a melhoria dos indicadores de sucesso acadêmico e bem estar, por meio da proposição de novas políticas e gestão da educação superior.

Qhato not to do?   Abstract: This study, part of a further longitudinal investigation (2019-2022), attached to a multidisciplinary group of Educational Research  Scholar Psychotherapy and Psychology, UFAM/CNPq, PROCAD/AMAZONIA-PPGEUFAM/UFPA/UFMT, CAPES process 8881.314288/2019-0, it is articulated methodological and theoretically with interfaces between the scholar and educational psychology, upper and scholar education pedagogy. It acts in the direction of understanding 5he effects og cognitive and contextual variables about the academic achievement and wellness in the university. The methodology to data collection is the application of own instrument cards with the support of Googledocs, the actual sample is quantity of n=1112 students from 51 private and public universities of different countries (Brazil, Mexico, Dominican Republic, Bolivia, Mozambique, Angola, Venezuela, Colombia, Spain and Portugal), from both male and female genders, aging between 18 and 54 years-old. The data were analyzed with the support of software Excel and SPSS, according to the interests of researchers and investigation focus. The actual results show the importance of the research about the themes cited in the initiative considering the impacts of the studied variables over the academic performance and wellness of the students as the teachers and technicians from upper education. There were found differences between countries, income, ethnic and gender. In the cases of the teachers and technicians it was found evidences of female exhaustion. The results could support the general administration, educative and psychopedagogy coordination and in a wide range, looking forward the better successful academic indicators and wellness, through the proposition of new policies and management of upper education.

Functional annotation of hypothetical proteins from the <i>Exiguobacterium antarcticum</i> strain B7 reveals proteins involved in adaptation to extreme environments, including high arsenic resistance

<div><p><i>Exiguobacterium antarcticum</i> strain B7 is a psychrophilic Gram-positive bacterium that possesses enzymes that can be used for several biotechnological applications. However, many proteins from its genome are considered hypothetical proteins (HPs). These functionally unknown proteins may indicate important functions regarding the biological role of this bacterium, and the use of bioinformatics tools can assist in the biological understanding of this organism through functional annotation analysis. Thus, our study aimed to assign functions to proteins previously described as HPs, present in the genome of <i>E</i>. <i>antarcticum</i> B7. We used an extensive <i>in silico</i> workflow combining several bioinformatics tools for function annotation, sub-cellular localization and physicochemical characterization, three-dimensional structure determination, and protein-protein interactions. This genome contains 2772 genes, of which 765 CDS were annotated as HPs. The amino acid sequences of all HPs were submitted to our workflow and we successfully attributed function to 132 HPs. We identified 11 proteins that play important roles in the mechanisms of adaptation to adverse environments, such as flagellar biosynthesis, biofilm formation, carotenoids biosynthesis, and others. In addition, three predicted HPs are possibly related to arsenic tolerance. Through an <i>in vitro</i> assay, we verified that <i>E</i>. <i>antarcticum</i> B7 can grow at high concentrations of this metal. The approach used was important to precisely assign function to proteins from diverse classes and to infer relationships with proteins with functions already described in the literature. This approach aims to produce a better understanding of the mechanism by which this bacterium adapts to extreme environments and to the finding of targets with biotechnological interest.</p></div

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved
