    Este artigo objetiva investigar e desenvolver, de forma necessariamente preliminar, alguns dos nexos poliédricos entre espiritualidade, filosofia, poesia e a experiência não-dual com a natureza em alguns pontos da obra poético-filosófica/espiritual de Henry D. Thoreau. Para tanto, destacaremos algumas de suas poesias, iluminando-as com o instrumental analítico oferecido pelo próprio Thoreau em algumas passagens da sua prosa espiritual/filosófica, já que para Thoreau, literatura, mitologia, filosofia e poesia são modulações linguísticas possíveis - e necessariamente incompletas - da impossibilidade de se referir de forma explícita àquela experiência arcaica e simbiótica não-dual com a natureza

    A statistical model for epigenetic control of miRNAs

    microRNAs are small, non-coding RNAs involved in post-transcriptional gene regulation. Since the dysregulation of only a few miRNAs can affect many biological pathways, miRNAs are thought to play a key role in cancer development and can be used as biomarkers for cancer diagnosis and prognosis. In order to understand how miRNA dysregulation leads to a cancer phenotype it is important to determine the basic regulatory mechanisms that drive miRNA expression. Although much is known about miRNA-mediated post-transcriptional regulation, little is known about the epigenetic control of miRNAs. Here, we performed cell-line specific miRNA promoter predictions and built a classification model for expressed and non-expressed miRNAs based on several epigenetic features, e.g. histone marks and DNA methylation at both, miRNA promoters and around miRNA hairpins. We were able to classify intragenic and intergenic miRNAs with an accuracy of 79% and 85%, respectively, and identified the most important features for classification via feature selection. Surprisingly, we found that DNA methylation seems to have a dual role in regulating miRNA expression at transcriptional level: at promoters, high levels of DNA methylation correlate with transcriptional repression, while around miRNA hairpins high levels of DNA methylation have a positive impact on the expression level of the mature miRNA

    Este artigo objetiva apresentar um relato de experiência da criação de recursos didáticos de informática básica para pessoas idosas. Nessa pesquisa, utilizou-se o design centrado no usuário objetivando torná-los mais acessíveis, precisos, concisos e inteligíveis para esses usuários. Este estudo envolveu a participação de 116 idosos, a maioria mulheres, com média de idade de 65 anos, apresentando escolaridade e classe social heterogêneas, todos concluintes do projeto de extensão "Oficinas de Informática para a Terceira Idade", entre 2008 a 2010, da Universidade Federal de Santa Catarina. Foram desenvolvidos dois recursos didáticos: um material didático impresso e duas videoaulas. Estes recursos didáticos foram avaliados pelo público-alvo por meio de questionários e com base em uma série de experimentos construídos em conjunto com estes usuários. _________________________________________________________________________________ ABSTRACTThis article aims to present an experience report on the creation of basic computer teaching resources for seniors. In this research, we used user-centered design seeking to make them more accessible, accurate, concise and intelligible to those users. This study involved 116 seniors, mostly women, with a mean age of 65 years, with heterogeneous education and social classes, all graduates of the extension project "Computer Workshops for Seniors", between 2008-2010, of the Federal University of Santa Catarina. We developed two educational resources: a printed teaching material and two video classes. These educational resources were evaluated by the target audience through questionnaires and based on a series of experiments built with those users

    A rede social de ajuda-mútua de Narcóticos Anônimos : a relevância do prestígio, da centralidade de intermediação entre os membros

    O presente trabalho teve como foco a recuperação de usuários de drogas decorrentes de suas inserções em grupos de ajuda-mútua de Narcóticos Anônimos. Descrito o método da construção e análise de uma rede social formada pelos membros de uma associação baseada nos princípios terapêuticos dos doze-passos. Foram avaliadas as dimensões proximidade, afastamento, padrinho e confiança na rede. Uma das análises relaciona os atores quanto ao prestígio e a rejeição, e outra sobre o controle do fluxo de informações entre eles. A topologia é de uma rede Livre de escala. Os resultados mostraram que o uso da teoria de redes permite entender o papel de cada membro do grupo. O efeito da dinâmica de grupo identifica lideres que influenciam as pessoas da rede. O compartilhamento de valores na re-educação tem permitido que a abstinência seja um valor crucial.This work was focused on drug user's recovery arising from its inserts in self-help groups of Narcotics Anonymous. Described the method of construction and analysis of a social network formed by members of an association based on therapeutic principles of the 12 steps. Proximity dimensions were evaluated, clearance, godfather and trust in the network. One of analysis lists the actors as the prestige and the rejection, and other on controlling the flow of information between them. The topology is a scale free network. The results showed that the use of the network theory allows us to understand the role of each member of the group. The effect of group dynamics identifies leaders influencing people network. Sharing values in re-education has allowed abstinence to be a crucial value in the recovery of drug us
