Através do presente estudo, procura-se analisar o Programa Mais Educação a partir do referencial Marxiano e marxista. Procura-se analisar as categorias Educação Integral, Esporte e Lazer, analisar relações das categorias com a discussão sobre o neoliberalismo, a sua influência no Estado brasileiro, além de marcos legais e contextuais. O processo de pesquisa ocorreu através da revisão bibliográfica, desenvolvida com base em materiais já elaborados, constituídos principalmente de livros e artigos científicos. Realizou-se o trato do cruzamento das primeiras abstrações sobre o objeto e o cruzamento da pesquisa documental com a revisão bibliográfica e com a pesquisa de campo. O nosso objetivo geral nesta pesquisa foi analisar os limites e as possibilidades na implementação do Esporte e do Lazer no PME e a problemática central da pesquisa: quais os limites e as possibilidades na implementação do Esporte e do Lazer no Programa Mais Educação na política local, nacional e na escola Esmerina Bou Habib de Abaetetuba/Pará (2008 - 2012)? Analisamos que o Programa Mais Educação tem sido um programa limitado à lógica do capital e do seu processo reprodutivo para o mercado de trabalho e a socialização de valores necessários a esta ordem. Por outro lado seria necessária uma Educação Integral e em tempo integral, na qual a construção de espaços deve ser prioridade, como uma alternativa para favorecer a escola pública, ou seja, é necessário mais tempo em uma nova escola. Percebeu-se que o Programa Mais Educação ainda não teve êxito em avançar na superação da escola de um turno para a construção de uma escola de dois turnos, os investimentos não são suficientes, a lógica da produtividade está presente no programa, inclusive na prioridade dada ao Esporte de rendimento. Percebeu-se que o macrocampo Esporte e Lazer é muito solicitado pelos alunos e que há uma aproximação entre as atividades deste macrocampo e as aulas de educação física, sendo que esta aproximação não deve ocasionar a substituição das aulas de educação física, caso que foi percebido durante a pesquisa de campo. Analisamos que a Educação Integral e em tempo integral será importante para a melhoria da educação no Brasil em termos estruturais, assim como uma melhor organização do trabalho pedagógico, valorização do processo educativo e do professor, aumentar as possibilidades educativas, ou seja, para o processo educativo ser mais qualitativo, crítico e dialético para a formação da classe trabalhadora. Contudo, entende-se que o Esporte deve ser tratado, a partir do paradigma da cultura corporal, como um elemento cultural humano deve ser socializado na escola no contexto da formação do novo homem e da nova mulher. Entende-se que a socialização do conhecimento sistematizado é necessária para a organização da classe trabalhadora em sua luta revolucionária. Nesse sentido, a educação escolar tem papel fundamental na luta pelo socialismo. Contudo, acreditou-se na relevância desta pesquisa, do ponto de vista social, por se estar propondo uma análise ampla e crítica que deverá dar conta do trato científico do objeto e das categorias de análise, afinado com perspectivas substancialmente transformadoras. Pretende-se que esta pesquisa possa contribuir para o debate das categorias Educação Integral, Esporte e Lazer.

This report of the BOOST2012 workshop presents the results of four working groups that studied key aspects of jet substructure. We discuss the potential of first-principle QCD calculations to yield a precise description of the substructure of jets and study the accuracy of state-of-the-art Monte Carlo tools. Limitations of the experiments' ability to resolve substructure are evaluated, with a focus on the impact of additional (pile-up) proton proton collisions on jet substructure performance in future LHC operating scenarios. A final section summarizes the lessons learnt from jet substructure analyses in searches for new physics in the production of boosted top quarks.

Developmental Dyslexia negatively affects children's reading and writing ability and, in most cases, performance in sensorimotor tasks. These deficits have been associated with structural and functional alterations in the cerebellum and the posterior parietal cortex (PPC). Both neural structures are active during visually guided force control and in the coordination of load force (LF) and grip force (GF) during manipulation tasks. Surprisingly, both phenomena have not been investigated in dyslexic children. Therefore, the aim of this study was to compare dyslexic and non-dyslexic children regarding their visuomotor processing ability and GF-LF coordination during a static manipulation task. Thirteen dyslexic (8-14YO) and 13 age- and sex-matched non-dyslexic (control) children participated in the study. They were asked to grasp a fixed instrumented handle using the tip of all digits and pull the handle upward exerting isometric force to match a ramp-and-hold force profile displayed in a computer monitor. Task performance (i.e., visuomotor coordination) was assessed by RMSE calculated in both ramp and hold phases. GF-LF coordination was assessed by the ratio between GF and LF (GF/LF) calculated at both phases and the maximum value of a cross-correlation function (r(max)) and its respective time lag calculated at ramp phase. The results revealed that the RMSE at both phases was larger in dyslexic than in control children. However, we found that GF/LF, rmax, and time lags were similar between groups. Those findings indicate that dyslexic children have a mild deficit in visuomotor processing but preserved GF-LF coordination. Altogether, these findings suggested that dyslexic children could present mild structural and functional alterations in specific PPC or cerebellum areas that are directly related to visuomotor processing.

The current context is unique in relation to the teaching of evolution in Brazil and the population's perception of evolution. On the one hand, it is said often about Darwinism in various media, especially due to the relatively recent commemoration of the two hundred years of the birth of Charles Darwin and one hundred and fifty years of the launch of the book The Origin of Species. On the other hand, it is clear, in recent years, a timid movement, more worryingly, in favor of equitable approach of creationist and evolutionist theories in the classroom. This article is a part of a research whose goal is to raise the design that Brazilian respondents have about the Darwinian view (which disregards the divine influence in the evolution of the species). The instrument used for data collection is a questionnaire, type Likert scale, which consists of a series of statements in which respondents must express their degree of agreement or disagreement with each statement. In this study, we present the results of the statement. "The thought of Darwin, which does not consider God as a participant in the process of evolution, is...". Analysis correlated with data on religion and education of the respondents are also held. The results point to a tendency of respondents not to accept the Darwinian view that disregards God's interference in the evolutionary process. The data also show that respondents' choices are influenced by religion and education. The frequency of responses that tend to accept the Darwinian view (which disregards the divine participation in the evolution of the species) is higher among respondents with higher levels of education. Adherents to religions "evangelical" tend to deny this view more often than followers of other religions. Given the potential risks of inserting creationist approaches in school education, it is necessary a discussion of the possible impacts of this rejection of Darwin's thinking (which does not consider God as a participant in the evolutionary process), indicated here, in the teaching of evolution.

The objective of the present study was to optimize a radiographic technique for hand examinations using a computed radiography (CR) system and demonstrate the potential for dose reductions compared with clinically established technique. An exposure index was generated from the optimized technique to guide operators when imaging hands. Homogeneous and anthropomorphic phantoms that simulated a patient's hand were imaged using a CR system at various tube voltages and current settings (40-55 kVp, 1.25-2.8 mAs), including those used in clinical routines (50 kVp, 2.0 mAs) to obtain an optimized chart. The homogeneous phantom was used to assess objective parameters that are associated with image quality, including the signal difference-to-noise ratio (SdNR), which is used to define a figure of merit (FOM) in the optimization process. The anthropomorphic phantom was used to subjectively evaluate image quality using Visual Grading Analysis (VGA) that was performed by three experienced radiologists. The technique that had the best VGA score and highest FOM was considered the gold standard (GS) in the present study. Image quality, dose and the exposure index that are currently used in the clinical routine for hand examinations in our institution were compared with the GS technique. The effective dose reduction was 67.0%. Good image quality was obtained for both techniques, although the exposure indices were 1.60 and 2.39 for the GS and clinical routine, respectively.
