Adolescentes em conflito com a lei: memórias e trajetórias de vivências na escola

O presente estudo objetiva desvelar, a memória de escola de adolescentes em conflito com a Lei e que cumprem medidas na Fundação da Criança e do Adolescente do Pará, na Unidade Socioeducativa de Internação de Val-de-Cães. A intenção é traçar por meio dos enunciados discursivos destes sujeitos, suas incursões no ambiente educacional e assim identificar o que os fizeram abandonar a escola de forma precoce e/ou apresentarem em seus currículos escolares um alto índice de repetência. As questões que norteiam este estudo são: Que fatores contribuíram para que estes adolescentes abandonassem o ambiente educacional de forma precoce? Até que ponto a escola e a exclusão social foram fatores relevantes para o envolvimento destes adolescentes com a violência e criminalidade? Qual o comprometimento da escola na formação dos adolescentes em conflito com a Lei, levando em consideração o papel da escola na formação do sujeito? Partindo das questões norteadoras o estudo objetiva identificar que Rede de Significados estão envolvidas nestes questionamentos. A amostra contou com a participação de 18 adolescentes na faixa etária de 12 a 17 anos de idade, com escolaridade de 13 série do ensino básico até a 83 série do ensino fundamental, nascidos no Estado do Pará, cumprindo medidas socioeducativas pelo ato infracional que vai do dano ao patrimônio público (Art. 163) a assalto seguido de morte (Art.12l c/c Art. 14). Foi utilizado como instrumentos de coleta de dados a entrevista semi-estruturada e documentos cedidos pela Fundação, como os prontuários, com os dados pessoais e acompanhamento de cada adolescente. O corpus da pesquisa foi analisado por meio dos seguintes eixos-temáticos: Escola; Família; Violência e Criminalidade; Relações Interpessoais e Perspectivas Futuras. O referencial teórico utilizado para análise dos dados segue a concepção de Bakhtin sobre a rede de significados e de autores que discutem aspectos relacionados aos eixos temáticos. Para tal utilizei autores como ROSSETTI e FERRElRA (2004); ARROYO (1997); BOSSA (2002); CORDIÉ (1996); VYGOTSKY (2000); PINTO (2002), entre outros. Nesta perspectiva, o objetivo foi o de encontrar correspondência com os princípios e critérios que pudessem contribuir para a fundamentação desta análise, favorecendo a interação entre as diferentes formas de produção de conhecimento, sobretudo, pelos dados apresentados ao processo de escolarização destes sujeitos, uma vez que contribuiu para reprovações, repetências, defasagens, e não raro, para a evasão escolar.

Explanations and Representations of Violence by School-age Brazilian Youths

The violence staged by young people has often been subjected to scientific analysis. The way youths speak, in their role as aggressors or as victims, is examined to determine how they experience violence in a number of different spheres. Repeated group interviews are used to analyze how violence is explained and depicted within the family, at school and in the neighbourhood by two groups of young people (14-17 years old) attending the same school on the outskirts of Rio Claro, Sao Paulo, Brazil. One of the groups involved is identified by the school as violent, and the other, as non-violent. Discourse analysis leads to two conclusions. First, the different contexts of violence infuse a mistrust of institutions, the environment and personal relationships into the subjects' experience, forming a fabric that clouds future prospects. Second, the group of youths identified as violent have a more simplistic, pessimistic view of reality: They see the world in black and white, and they lay no stock in the possibility that violence can be avoided. Consequently, they use violence and understand violence as a defensive strategy that gives one identity. On the other hand, the group identified as nonviolent feels it possible to intervene in situations with nonviolent tools like words. For the young subjects, violence is a context that they assume; it cancels their ability to identify rules and institutions, but it does not generate an effective interaction strategy. Violence causes their social microcontext (in which action prevails over meaning or meaning equals action) to assume overblown dimensions. Any intervention strategy must take into account this indissoluble unity between meaning and action.

Aproveitamento de resíduos na composição de painel sarrafeado amarrado: um estudo econômico

The manufacture of plywood panel already has about eighty years in Brazil. In general, plywood panels differ by their nature, composition and manufacturing; the most common MDF, OSB, particle and the joist. Some of these products can be generated fromindustrial waste, as the panelblockboard, you can use in their training waste destop boards (Battens), from industrial processes or processing of primary wood. This work aims to present the detailed study of the economic viability of utilization of industrial solid waste timber through the acquisition of a machine amarradeira of joists in a wood processing unit in city Itapeva-SP. We studied the application of wastein the composition of kernels blockboard panel tied its commercial acceptance and future prospects market. We noticed great economic advantage in investing in the study, compared with the transformation process of the joists in biomass energy, although the investment decision involves not only financial matters but also the acceptance market the product to be manufactured

Relações Públicas nas agências de comunicação: uma análise dos discursos dos mercados

Public Relations is an area of communication that has many definitions given by both professional associations and by many authors. Academic and professional discussions on a precise definition of the area are recurrent. Considering this issue, it was decided to study the relationship between public relations and communications agencies, assuming that this is a market segment that includes the public relations. This paper analyzes the discourses of communication agencies and how the Public Relations are handled by them. For this, it was used theories about the history of public relations as well as definitions and concepts of its main authors. Furthermore, we present the characteristics of communication agencies, the contexts associated with its emergence in Brazil and the future prospects of this market segment in the opinion of the professionals who work in it. The study about the discourses of communications agencies was based on French Discourse Analysis, using books from important authors of the area, such as José Fiorin and Helna Brandão. The discourses analyzed were those present on websites of three communications agencies in the state of Sao Paulo. It was noted that not always the participation of public relations in communication agencies is highlighted, although the services of these agencies are based on techniques and typical functions of Public Relations. Above all, what the discourses are seeking to highlight are the experience and expertise in organizational communication owned by its staff

Whither lung EIT: Where are we, where do we want to go and what do we need to get there?

Breathing moves volumes of electrically insulating air into and out of the lungs, producing conductivity changes which can be seen by electrical impedance tomography (EIT). It has thus been apparent, since the early days of EIT research, that imaging of ventilation could become a key clinical application of EIT. In this paper, we review the current state and future prospects for lung EIT, by a synthesis of the presentations of the authors at the 'special lung sessions' of the annual biomedical EIT conferences in 2009-2011. We argue that lung EIT research has arrived at an important transition. It is now clear that valid and reproducible physiological information is available from EIT lung images. We must now ask the question: How can these data be used to help improve patient outcomes? To answer this question, we develop a classification of possible clinical scenarios in which EIT could play an important role, and we identify clinical and experimental research programmes and engineering developments required to turn EIT into a clinically useful tool for lung monitoring.

EoR in alternative cosmological scenarios

The aim of this Thesis is to investigate the possibility that the observations related to the epoch of reionization can probe not only the evolution of the IGM state, but also the cosmological background in which this process occurs. In fact, the history of the IGM ionization is indeed affected by the evolution of the sources of ionizing photons that, under the assumption of a structure formation paradigm determined by the hierarchic growth of the matter uctuations, results strongly dependent on the characteristics of the background universe. For the purpose of our investigation, we have analysed the reionization history in innovative cosmological frameworks, still in agreement with the recent observational tests related to the SNIa and the CMB probes, comparing our results with the reionization scenario predicted by the commonly used LCDM cosmology. In particular, in this Thesis we have considered two different alternative universes. The first one is a at universe dominated at late epochs by a dynamic dark energy component, characterized by an equation of state evolving in time. The second cosmological framework we have assumed is a LCDM characterized by a primordial overdensity field having a non-Gaussian probability distribution. The reionization scenario have been investigated, in this Thesis, through semi-analytic approaches based on the hierarichic growth of the matter uctuations and on suitable assumptions concerning the ionization and the recombination of the IGM. We make predictions for the evolution and the distribution of the HII regions, and for the global features of reionization, that can be constrained by future observations. Finally, we brie y discuss the possible future prospects of this Thesis work.

Imetelstat (GRN163L)--telomerase-based cancer therapy

Telomeres and telomerase play essential roles in the regulation of the lifespan of human cells. While normal human somatic cells do not or only transiently express telomerase and therefore shorten their telomeres with each cell division, most human cancer cells typically express high levels of telomerase and show unlimited cell proliferation. High telomerase expression allows cells to proliferate and expand long-term and therefore supports tumor growth. Owing to the high expression and its role, telomerase has become an attractive diagnostic and therapeutic cancer target. Imetelstat (GRN163L) is a potent and specific telomerase inhibitor and so far the only drug of its class in clinical trials. Here, we report on the structure and the mechanism of action of imetelstat as well as about the preclinical and clinical data and future prospects using imetelstat in cancer therapy.
