In Brazil, as in other countries, youth becomes the group most affected by unemployment and pushed to the margins of society. In the past, authorities adopted policies to control and repress young people through premature integration into the labor market. Since 1990, international organizations supported vocational training activities in several countries. In an attempt to remedy this situation, compensatory social and educational policies were created in Brazil, functioning as mechanisms for the perpetuation of social and educational inequalities, and favoring the maintenance of the capitalist interests of the hegemonic classes. Critical thinkers suggest that improving the skills of young people is no guarantee of employment, because there is insufficient jobs creation for the general population. Based on this reality, the object of this study are the educational policies of vocational training for yoth initiated in the Lula government (2003-10), followed by Dilma?s first government (2011-14). We aimed at the policies to qualify young people for the labor market through programs such as Projovem, whose goal is the qualification of youth living in areas devoid of basic social services. According to the government discourse, the job opportunities exist but lack qualified professionals to take them, attracting young people to participate in programs such as ProJovem. However, due to its precarious nature, these do not guarantee a reduction in youth unemployment. In view of such reality, we propose a review of public policy goals regarding professional qualification and care given to youth issues by Brazilian government authorities, using the experience of ProJovem in Mesquita, RJ. Our main sources were bibliographical material and analysis of primary and secondary sources relating to youth, public policies and vocational education programs. We conclude that the main objective of these programs is not to prepare youth for the labor market, but to contain a possible threat that poor and idle youth may become to society, because such programs are developed in peripheral and poor regions. During our survey in search for the actual situation of the program, we interviewed ProJovem students and teachers about their hopes and difficulties. In doing so we sought to raise the main problems related to the Program in the voice of its members, and they confirmed our initial suspicions. We hope this work will contribute to the construction of new public policies that truly meet the needs of young people of the lower classes. / Parte-se do pressuposto de que o desemprego da popula??o jovem ? um dos desafios das sociedades globalizadas, com postos de trabalho escassos e especializados. O grupo de jovens comp?e o segmento mais atingido pelo desemprego tamb?m no Brasil. Cria-se uma popula??o ? margem da sociedade. No passado as autoridades adotaram pol?ticas para o controle e a repress?o dos jovens via integra??o precoce ao mundo do trabalho. A partir de 1990, organismos internacionais apoiaram a??es de qualifica??o profissional em diversos pa?ses, inclusive no Brasil. Na tentativa de remediar essa situa??o, foram criadas pol?ticas sociais e educacionais compensat?rias, assistenciais e de controle, as quais atuam como mecanismos de perpetua??o das desigualdades sociais e educacionais, agindo na manuten??o dos interesses da classe hegem?nica e do capital. Pensadores cr?ticos sugerem que melhorar as habilidades dos jovens n?o ? garantia de emprego, pois h? gera??o insuficiente de postos de trabalho. Baseado nessa realidade, o objeto deste estudo s?o as pol?ticas p?blicas educacionais de qualifica??o profissional de jovens iniciadas no governo Lula (2003-10), com continuidade no primeiro governo Dilma (2011-14). Pol?ticas destinadas a qualificar os jovens para o ingresso no mercado de trabalho por meio de programas como o ProJovem, cuja a meta ? a qualifica??o profissional dos jovens que vivem em territ?rios destitu?dos dos servi?os sociais b?sicos. De acordo com o discurso oficial, h? oportunidades de trabalho, mas faltam profissionais qualificados para assumi-las, atraindo os jovens para participarem de programas como o ProJovem. Entretanto, devido ? sua ligeireza e precariedade, estes n?o garantem uma redu??o do desemprego juvenil. Diante dessa realidade, propomos uma avalia??o dos objetivos das pol?ticas p?blicas de qualifica??o profissional e a discuss?o do atendimento dado ?s quest?es juvenis em nosso pa?s, tomando como modelo a experi?ncia do ProJovem no Munic?pio de Mesquita na Baixada Fluminense. Utilizamos a an?lise de material bibliogr?fico de fontes prim?rias e secund?rias referentes ? juventude, pol?ticas p?blicas e programas de educa??o profissional. Partimos da hip?tese que o objetivo principal desses programas n?o ? qualificar o jovem para o mercado de trabalho, mas conter a poss?vel amea?a que o jovem pobre e desocupado pode se tornar para a sociedade, visto que s?o desenvolvidos em regi?es perif?ricas. Na busca para conhecer a realidade dos atores do ProJovem em Mesquita, ouvimos alunos e professores, sobre os seus anseios e dificuldades. Buscamos assim levantar os principais problemas relacionados ao Programa na voz de seus usu?rios, o que confirmou nossas suspeitas iniciais. Esperamos que este trabalho contribua para a constru??o de novas pol?ticas p?blicas que realmente atendam as necessidades dos jovens das camadas populares.

From the aggravation of this impact and major perception of it by the society and government, there is a change adopted by companies, which focus only on the economic role of job creation and taxes payment, and begins to value its paper and relationship with society and environment. How enterprises impact in the territories in which they are installed should contributed to the development. One of the ways to contribute are the actions in Business Social Responsibility, acting in social projects and environmental. This dissertation has the objective analyze the Cooperatives Solidarity Program of Recycle of the Information Center of Environment and Recycle ? Recicloteca of the Non Governmental Organization (ONG) Ecomarapendi sponsored by the with the contribution to the territorial development and social inclusion of the community where the cooperatives Coopar and Coopcarmo are located and reflect about the role of business social responsibility in the environmental and social actions. The present theme is justified because the Baixada Fluminense is an area of expressive populational and industrial concentration and presents economic growth, however the human development observed doesn?t accompanies the growth. As methodology it was used bibliographical research and interviews with the Recicloteca, cooperatives and presidents of Coopar and Coopcarmo. The participation in the program brought economic, social and environmental benefits for the cooperatives; however there is the necessity of continuity of the actions. / As empresas influenciam a organiza??o social e impactam o meio ambiente onde se localizam. A partir do agravamento desse impacto e da maior percep??o deste por parte da sociedade e governo, h? uma mudan?a na postura adotada pelas empresas, que abandona o foco dos neg?cios apenas no papel econ?mico de gera??o de empregos e pagamento de impostos, e passa a valorizar o seu papel e relacionamento com a sociedade e meio ambiente. Uma das formas de contribui??o s?o as a??es de Responsabilidade Social Empresarial, atrav?s da atua??o em projetos sociais e ambientais. Esta disserta??o tem por objetivo analisar o Programa Reciclagem Solid?ria Cooperativas do Centro de Informa??es sobre Reciclagem e Meio Ambiente ?

O presente tema justifica-se, pois, a Baixada Fluminense ? uma ?rea de expressiva concentra??o populacional e industrial e apresenta crescimento econ?mico, por?m o desenvolvimento humano observado n?o acompanha tal crescimento. Como metodologia utilizou-se pesquisas bibliogr?ficas e entrevistas com a Recicloteca, cooperados e presidentes da Coopar e Coopcarmo. A participa??o no Programa trouxe benef?cios econ?micos, sociais e ambientais para as cooperativas atrav?s da legaliza??o das cooperativas e concess?o de equipamentos tornaram a coleta, armazenamento e transporte dos materiais mais eficientes, por?m h? necessidade de continuidade nas a??es de apoio ?s cooperativas de reciclagem.

Such question is directly related with the territorial approach of rural development that advocates the participatory policy in deliberative forums capable of integrate social actors, especially those traditionally excluded of the process of political decision-making, with the purpose the identification of local demands and the established of concerted actions of rural development . The social management, in this case, is the dialogic relationship between the social actors of the public sphere, which the finality is the process of discussion and deliberations of actions of development through an operative authority shared. The territory, in this case, is faced how an active unity of development, having a potential spatiality to the construction of projects of development socially concerted. Built upon such decision, the research came from two presuppositions: (1) the practice of management social in rural territory is conditioned to the constitution of deliberative public spheres and (2) requires the provision of participative conditions of generate opportunities and capacities to insertion of the civil society in the decision process. The objects of study adopted consisted in the Programa Territ?rios da Cidadania da Secretaria de Desenvolvimento Territorial do Minist?rio do Desenvolvimento Agr?rio and the Programa Nacional de Apoio ao Desenvolvimento dos Territ?rios do Instituto Nacional de Tecnologia Agropecu?ria do Minist?rio da Agricultura, Pecu?ria e Pesca of Brazil and Argentina, respectively. The research method consisted in the study of cases compared between the Territ?rio da Cidadania Noroeste Fluminense, in Brazil and the Territ?rio Oeste Pampeano, in Argentina. The data collect counted with bibliographic researches, documental and of camp. In relation to these, were realized techniques of simple and participative observation in investigated territories and at the same time, were realized semi structured interviews with state representatives and with family agriculture. The treatment of data were realized of quality form from the analyze technique of content by mixed grade, in which the categories of analysis were preliminary defined, being incorporated also during the analyze process. The categorization counted with three criteria institutional-political, territorial and social dismembered in a group of unities of correspondents analyzes. The results point, in the argentine case, the social management is related with the construction of social relations and of a discussion process, characterized for dialogicity and intersubjectivity, from the existence of common identity between the small caprine producers. In Brazilian case, the public spheres contribute to integrate the diverse publics belong to the segment of family agriculture and constitute an expression space of demands and acquisition of social rights for those representations more mobilized and social organized. However, the social management faces difficulties in the appropriation of decision process by civil society, principally, by those segments on disadvantage that can not realize participative conditions to your deliberative insertion, as in the Territ?rio da Cidadania Noroeste because of the predomination of strategic management as in the Territ?rio Oeste by the absence of institutionalization of participatory decision-making mechanisms. / A pergunta central que o estudo buscou responder foi: como a gest?o social ? estabelecida em programas de desenvolvimento territorial rural no Brasil e na Argentina? Tal questionamento est? diretamente relacionado com a abordagem territorial do desenvolvimento rural que preconiza a diretriz participativa em f?runs deliberativos capazes de integrar atores sociais, sobretudo aqueles tradicionalmente exclu?dos do processo de tomada de decis?o pol?tica, tendo por finalidade a identifica??o de demandas locais e o estabelecimento de a??es concertadas de desenvolvimento rural. A gest?o social, neste caso, constitui a rela??o dial?gica entre os atores sociais da esfera p?blica, na qual a finalidade ? o processo de discuss?o e de delibera??o de a??es de desenvolvimento por meio de autoridade decis?ria compartilhada. O territ?rio, deste modo, ? visto como unidade ativa do desenvolvimento, tendo espacialidade potencial para constru??o de projetos de desenvolvimento concertados socialmente. Sustentada em tal discuss?o, a pesquisa partiu de dois pressupostos: (1) a pr?tica da gest?o social em territ?rios rurais est? condicionada a constitui??o de esferas p?blicas deliberativas e (2) requer a provis?o de condi??es participativas capazes de gerar oportunidades e capacidades para a inser??o da sociedade civil no processo decis?rio. Os objetos de estudo consistiram no Programa Territ?rios da Cidadania da Secretaria de Desenvolvimento Territorial do Minist?rio do Desenvolvimento Agr?rio e no Programa Nacional de Apoyo al Desarrollo de los Territorios do Instituto Nacional de Tecnolog?a Agropecuaria do Ministerio da Agricultura, Ganader?a y Pesca, do Brasil e da Argentina, respectivamente. O m?todo de pesquisa adotado foi o estudo de casos comparado entre o Territ?rio da Cidadania Noroeste Fluminense, no Brasil, e o Territ?rio Oeste Pampeano, na Argentina. A coleta de dados contou com pesquisas bibliogr?fica, documental e de campo. Em rela??o a esta ?ltima, foram realizadas t?cnicas de observa??o simples e participante nos territ?rios investigados, bem como realizadas entrevistas semiestruturadas com representantes do Estado e da agricultura familiar. O tratamento dos dados foi realizado de forma qualitativa, a partir da t?cnica de an?lise de conte?do por grade mista, na qual categorias de an?lise foram definidas preliminarmente, sendo incorporadas tamb?m durante o processo de an?lise. A categoriza??o contou com tr?s crit?rios: pol?tico-institucional, territorial e social desmembrados em um conjunto de unidades de an?lises correspondentes. Os resultados apontam, que no caso argentino, a gest?o social ? percebida na constru??o de rela??es sociais e no processo de discuss?o, sustentados na dialogicidade e na intersubjetividade, a partir de uma identidade comum entre os pequenos produtores. No caso brasileiro, as esferas p?blicas contribuem para integrar os diversos p?blicos pertencentes ao segmento da agricultura familiar, al?m de constitu?rem um espa?o de express?o das reivindica??es e de conquista de direitos sociais por aquelas representa??es mais mobilizadas e organizadas socialmente. Contudo, a gest?o social enfrenta barreiras na apropria??o do processo decis?rio pela sociedade civil, principalmente, pelos segmentos em desvantagem que n?o conseguem efetivar condi??es participativas para sua inser??o deliberativa, seja no Territ?rio da Cidadania Noroeste pelo predom?nio da gest?o estrat?gica seja no Territ?rio Oeste pela aus?ncia de institucionaliza??o de mecanismos decis?rios participativos.

Moreover, the benefits attributed to its implementation may surpass the commercial level of the producer and enhance the development of the territory, and as well to increase receptive tourism and enhance the cultural heritage. This thesis aims to analyze the effectiveness of the geographical indication as a catalyst instrument for sustainable rural development of the territory, from the perspective of the social actors involved. The method used for the research development was the study of multiple cases, with an exploratory and descriptive purpose in two distinct areas of cheese production: the municipality of Serro, in Minas Gerais State, and in Celorico Beira, Portugal, where the Serra da Estrela cheese is produced. In the period from December 12th, 2015 to April 30th, 2016, in Portugal, and from 22th to 29th, 2016, in Serro - Minas Gerais, there were many research activities. Among them, non-participant observations, photographic records, informal conversations, application of semi-structured interviews with the actors involved in the proposed thematic, technical visits to cheese production units and cultural museums, festivals and fairs related to cheese, all within the geographical boundary of the surveyed geographical indications. The information of applied interviews was analyzed using a content analysis group of techniques, under the perspective of Bardin (2004). The results revealed that in both cases studied, the existence per si of a geographical indication is not capable of promoting sustainable development of the territory, since other factors such as the role of producers, social management in decision making, and a consistent social capital are key to the success of GIs in adding value to the certified product and improving the quality of life for the producers. The Protected Designation of Origin Serra da Estrela cheese, although well known by its quality and tradition, proved to be ineffective in promoting sustainable rural development in the Portuguese territory investigated. The analysis of the effectiveness of the geographical indication of the cheese from Minas studied was not feasible, since the correspondent seal has not yet been implemented. Then, it is responsibility of all social actors presented in this research to transform the current panorama and to make their respective geographical indications true catalyst tools in the sustainable development of their territories. / O car?ter protetivo contra poss?veis falsifica??es ou imita??es e a agrega??o de valor ao produto s?o as principais finalidades da indica??o geogr?fica (IG). Ademais, os benef?cios atribu?dos ? sua implementa??o podem tanto transpassar as porteiras do produtor e potencializar o desenvolvimento do territ?rio, quanto incrementar o turismo receptivo e a valoriza??o do patrim?nio cultural. Este trabalho de tese tem como objetivo analisar a efetividade da indica??o geogr?fica como um instrumento catalisador do desenvolvimento rural sustent?vel do territ?rio, sob a ?tica dos atores sociais envolvidos. O m?todo utilizado para o desenvolvimento da pesquisa foi o estudo de casos m?ltiplos, com o prop?sito explorat?rio e descritivo, em dois territ?rios distintos de produ??o queijeira: o munic?pio do Serro, produtor do Queijo do Serro, em Minas Gerais, e o concelho de Celorico da Beira, onde se produz o Queijo da Serra da Estrela, em Portugal. No per?odo de 12 de dezembro de 2015 a 30 de abril de 2016, em Portugal, e de 22 a 29 de maio de 2016, em Serro ? Minas Gerais, a pesquisa foi desenvolvida com v?rias atividades. Entre elas, observa??es n?o participantes, registros fotogr?ficos, conversas informais, aplicadas entrevistas semiestruturadas com os atores envolvidos na tem?tica proposta, e feitas visitas t?cnicas a unidades produtoras do queijo e culturais a museus, festas e feiras relacionadas ao queijo dentro do limite geogr?fico das indica??es geogr?ficas pesquisadas. As informa??es das entrevistas aplicadas foram analisadas por meio do conjunto de t?cnicas da an?lise de conte?do, sob a perspectiva de Bardin (2004). Os resultados revelaram que, em ambos os casos estudados, a exist?ncia por si s? de uma indica??o geogr?fica ? incapaz de promover o desenvolvimento sustent?vel do territ?rio, pois outros fatores, tais como, o protagonismo dos produtores, a gest?o social nas tomadas de decis?es e um capital social consistente s?o fundamentais para o sucesso da IG, ? agrega??o de valor ao produto certificado e ? melhoria da qualidade de vida dos produtores. A Denomina??o de Origem Protegida Queijo Serra da Estrela, apesar de sua reconhecida qualidade e da tradi??o que j? possu?a, mostrou-se pouco efetiva na promo??o do desenvolvimento rural sustent?vel no territ?rio portugu?s investigado. J? a an?lise da efetividade da indica??o geogr?fica do queijo mineiro estudado como um instrumento catalizador do desenvolvimento territorial sustent?vel n?o foi vi?vel pelo fato de o selo correspondente ainda n?o ter sido implementado.

The soil classification is the basis for determining the potential use of the land, ie, guide the sustainable use of the same. For this situation, it is known that many factors corroborate the frame. Among these the human factor has great weight in this matter because, Survey and Soil Classification (LCSs) are present on curricular content for training of Agronomists, Forestry Engineers, etc.., and scholars and authorities in the field of Soil Science have signaled that the Higher Education Institutions (specifically undergraduate) come crashing in training these professionals supposedly trained and qualified to the activity of LCSs, considering that the courses that form such professionals invariably advocated among other things "solid scientific general and professional ... "what prescribes the contents of their curricular chord in the National Curriculum Guidelines. Informally today, teachers generally do mind that the problem lies in the structure of undergraduate courses regarding aspects: design of a workload of disciplines; literature indicated in ement?rios; disciplines sequence prerequisites; opportunity of additional knowledge through elective courses, etc.. Thus, sensing data bring to literature that deal with the subject, aimed this work was to analyze the conditions for teaching of LCSs course of Forestry's IFMT - Campus C?ceres through its Political-Pedagogical Project (PPP) as all the above aspects. This research is exploratory, Documentary and Quanti-qualitative nature. Included in the questionnaire data collection and content analysis for inferences. The inferences are that the references (data obtained from educators in the field of Soil Science of the five geographical regions through a questionnaire) indicate that the PPP course has limitations that may affect the teaching-learning LCSs and achieve, in this regard (themes mentioned), the professional profile designed by the course concerning "solid scientific and professional general enabling absorb and develop technology." The limitations were: inadequate sizing workload in disciplines that include LCSs and related activities; literature indicated in these ement?rio not include modern features with the potential to collaborate with a better education, sequence of disciplines inappropriate prerequisites discipline that includes these activities and, lack of opportunity for complementation of knowledge related to these themes via list of electives. Given the paucity of information in the literature that addresses on the subject, the data generated will assist both in the construction and / or reformulation of PPP courses in general as well as instigating research on the topic. / Apesar de toda produ??o agropecu?ria que saem dos solos brasileiros, pujan?a do agroneg?cio que se noticia, a maior parte dos solos do Pa?s n?o est?o classificados a n?vel adequado para utiliza??o do agricultor; ou melhor, dizendo, as propriedades agr?colas e florestais, em sua maioria, n?o possuem um mapeamento de seus solos, logo, majoritariamente produtores e profissionais tecnicamente atuantes nestas propriedades n?o possuem um conhecimento detalhado dos tipos de solos que se t?m trabalhado. A classifica??o dos solos serve de base para determina??o do potencial de uso das terras, ou seja, norteiam a utiliza??o sustent?vel das mesmas. Para esta situa??o, sabe-se que muitos fatores corroboram com o quadro. Dentre estes o fator humano tem grande peso nesta quest?o; pois, Levantamento e Classifica??o de Solos (LCSs) s?o conte?dos presentes nas matrizes curriculares para forma??o de Engenheiros Agr?nomos, Engenheiros Florestais, etc.; e, estudiosos e autoridades da ?rea de Ci?ncia do Solo t?m sinalizado que as Institui??es de Ensino Superior (especificamente cursos de gradua??o) v?m falhando na forma??o desses profissionais pressupostamente capacitados e habilitados para a atividade de LCSs; tendo em vista que, os cursos que formam tais profissionais, invariavelmente, preconizam dentre outras coisas ?s?lida forma??o cientifica e profissional geral...? daquilo que prescreve os conte?dos de suas matrizes curriculares em acorde com as Diretrizes Curriculares Nacionais. Informalmente na atualidade, docentes em geral cogitam que o problema est? na estrutura dos cursos de gradua??o quanto aos aspectos: dimensionamento de carga hor?ria de disciplinas; bibliografia indicada em ement?rios; sequencia de disciplinas pr?-requisitos; oportunidade de complementa??o de conhecimentos via disciplinas optativas, etc. Dessa forma, intuindo trazer dados ? literatura que versem sobre o assunto, objetivou-se com este trabalho analisar as condi??es para atividades de ensino de LCSs do curso de Engenharia Florestal do IFMT - Campus C?ceres atrav?s de seu Projeto Pol?tico-Pedag?gico (PPP) quanto aos aspectos supramencionados. A presente pesquisa ? Explorat?ria, Documental e de natureza Quanti-qualitativa. Incluiu o Question?rio na coleta dos dados e a An?lise de Conte?do para as infer?ncias. As infer?ncias s?o de que as refer?ncias (dados obtidos junto a educadores da ?rea de Ci?ncia do Solo das cinco regi?es geogr?ficas brasileiras atrav?s de question?rio) indicam que o PPP do curso apresenta limita??es que podem comprometer o ensino-aprendizado de LCSs e alcan?ar, neste quesito (tem?ticas mencionadas), o perfil profissional projetado pelo curso concernente a ?s?lida forma??o cient?fica e profissional geral que possibilite absorver e desenvolver tecnologia?. As limita??es encontradas foram: dimensionamento inadequado de carga hor?ria em disciplinas que contemplam LCSs e atividades correlatas; bibliografia indicada no ement?rio destas n?o incluem recursos modernos com potencial de colaborar com uma melhor forma??o; sequ?ncia inapropriada de disciplinas pr?-requisitos a disciplina que contempla estas atividades; e, inexist?ncia de oportunidade para complementa??o dos conhecimentos relacionados a tais tem?ticas via rol de disciplinas optativas.

Patients of Hutchinson-Gilford Progeria Syndrome (HGPS) display a rate of aging up to ten times that of normal human populations. It might be expected that HGPS cells would have a decreased ability to repair DNA damage through the cell cycle as compared to normal cells such as those of the BJ cell line since DNA damage accumulation is a hallmark phenotype of aging. On earth, we are exposed to far more ultraviolet-B (UV-B, 280-315 nm) and UV-A (315-400 nm) than UV-C (100-280 nm) radiation, since the latter is filtered-out by the atmospheric ozone layer. The relative sensitivity of prematurely aging HGPS cells to UV-B irradiation is unknown. It was hypothesized that the normal fibroblast cell line (BJ) would exhibit a higher rate of DNA repair and a higher level of cell viability after exposure to ultraviolet radiation than would be observed with the HGPS cells, and that these differences would be greater as the HGPS cells age in culture. A Cell-Titer Blue Viability Assay (Promega) was used to determine the effect of UV-B and UV-C on metabolic activity, an indicator for cell viability, in HGPS, BJ, and A549 (a human lung carcinoma) cells. A translesion DNA synthesis protein, pol-η, and several other DNA transcription and repair-related proteins also were hypothesized to be altered in the HGPS cell line, both before and after UV-induced DNA damage, as compared to the BJ cell line. Western blotting was used to monitor these proteins in BJ and HGPS cells following UV-C exposure. No differences in short-term viability were observed between BJ and HGPS cells, reflecting similarities in their repair abilities on the cellular level; however, there were significant differences in long-term viability. Enzyme Linked Immunosorbant Assays (ELISA) revealed a significant difference in DNA repair at the molecular level. Moreover, Western blotting revealed differences in the amounts of several repair-related proteins following UV exposure, including pol-η, an important trans-lesion synthesis protein. Although the difference in DNA repair did not appear at the cellular level, it is apparent that HGPS cells show a greater sensitivity to both UV-B and UV-C irradiation as compared to normal BJ fibroblasts and A549 carcinoma cells.

<p>Cellular processes involved in the conversion of the genetic information from DNA into a protein are often regulated by reversible phosphorylation reactions. By modulating the phosphorylated status of key proteins their activity can either be enhanced or repressed. In this thesis I have studied the significance of phosphorylation in the regulation of transcription and splicing using human adenovirus as a model system.</p><p>The results show that the activity of the cellular SR family of splicing enhancer or repressor proteins are reduced in adenovirus infected nuclear extracts by a virus-induced hypophosphorylation. The viral E4-ORF4 was shown to induce SR protein dephosphorylation by recruiting the cellular protein phosphatase PP2A. The E4-ORF4/PP2A complex was shown to relieve the SR protein-mediated repression of late virus-specific splicing and further activate alternative splicing in transiently transfected cells. Collectively, these results showed that alternative splicing, like many other biological processes, is regulated by reversible protein phosphorylation.</p><p>Similarly, the cellular p32 protein was shown to cause hypophosphorylation of the SR protein ASF/SF2 resulting in a reduced RNA binding capacity of ASF/SF2.

Cellular processes involved in the conversion of the genetic information from DNA into a protein are often regulated by reversible phosphorylation reactions. By modulating the phosphorylated status of key proteins their activity can either be enhanced or repressed. In this thesis I have studied the significance of phosphorylation in the regulation of transcription and splicing using human adenovirus as a model system. The results show that the activity of the cellular SR family of splicing enhancer or repressor proteins are reduced in adenovirus infected nuclear extracts by a virus-induced hypophosphorylation. The viral E4-ORF4 was shown to induce SR protein dephosphorylation by recruiting the cellular protein phosphatase PP2A. The E4-ORF4/PP2A complex was shown to relieve the SR protein-mediated repression of late virus-specific splicing and further activate alternative splicing in transiently transfected cells. Collectively, these results showed that alternative splicing, like many other biological processes, is regulated by reversible protein phosphorylation. Similarly, the cellular p32 protein was shown to cause hypophosphorylation of the SR protein ASF/SF2 resulting in a reduced RNA binding capacity of ASF/SF2. This change in ASF/SF2 RNA binding also had a drastic effect on the function of ASF/SF2 as a regulatory protein affecting splice site choice. The cellular p32 protein and the viral E4-ORF4 protein both target the same cellular splicing factor, ASF/SF2. However, they regulate splicing by different mechanisms. E4-ORF4 recruits a phosphatase to dephosphorylate ASF/SF2, while p32 sequester ASF/SF2 in an inactive complex. Further, we demonstrated that overexpression of p32 during a lytic infection suppressed transcription from the adenovirus major late transcription unit. p32 induced a selective repression of CAAT-box containing promoters indicating the involvement of the transcription factor CBF/NF-Y in this regulation. A further analysis showed that p32 caused a hyperphosphorylation of the CTD of RNA Pol II, which resulted in a significant reduction in the processivity of Pol II during the elongation phase of transcription. In summary, we have shown that E4-ORF4 regulates the activity of splicing regulatory SR proteins, and that p32 regulates the activity of the SR protein ASF/SF2 in splicing and Pol II processivity during transcription elongation. Mechanistically, both E4-ORF4 and p32 appears to function by regulating the phosphorylated status of key cellular proteins involved in these processes.

Understanding static and dynamic nonlinear behavior of pipes and risers is crucial for the design aspects in offshore engineering fields. In this work, we examine two nonlinear problems in offshore engineering field: vortex Induced vibration of straight horizontal pipes, and boundary layer static solution of inclined risers. In the first study, we analyze the effect of the internal velocity of straight horizontal pipe and obtain the vortex induced vibration forces via coupling the pipe equation of motion with the recently modified Van Der Pol oscillator governing the lift coefficient. Our numerical results are obtained for two different pipe configurations: hinged-hinged, and clamped- clamped. The results show that the internal velocity reduces the vibration and the oscillation amplitudes. Also, it is shown that the clamped-clamped pipe configuration offers a wider range of internal velocities before buckling instability occurs. The results also demonstrate the effect of the end condition on the amplitudes of vibration. In the second study, we develop a boundary layer perturbation static solution to govern and simulate the static behavior of inclined risers. In the boundary layer analysis, we take in consideration the effects of the axial stretch, applied tension, and internal velocity. Our numerical simulation results show good agreement with the exact solutions for special cases. In addition, our developed method overcomes the mathematical and numerical limitations of the previous methods used before.

Para esta constru??o analisa-se o exerc?cio profissional dos assistentes sociais nesses espa?os, em que se originam e se encontram num cen?rio de interesses divergentes que convivem em plena tens?o e luta de classes, cuja interven??o profissional se insere no movimento de reprodu??o das rela??es sociais. As institui??es de ensino s?o espa?os s?cio-institucionais inseridos neste contexto e facilitadores para a compreens?o dos perfis pedag?gicos do assistente social, uma vez que o seu papel pol?tico e sua pr?tica educativa definem com maior clareza as rela??es pedag?gicas do assistente social. No processo de interven??o, o assistente social nestas institui??es, se volta ao atendimento das condi??es materiais dos usu?rios estudantes e suas necessidades transformadas em demanda e requisi??es - via os servi?os sociais prestados por essas institui??es, ao mesmo tempo, em que interv?m na maneira de pensar e agir desses indiv?duos envolvidos no seu cotidiano profissional na perspectiva de um direcionamento ideol?gico/pol?tico mediante a??o educativa. Neste sentido, analisa-se o cotidiano profissional e seus determinantes a partir de um entendimento cr?tico, em fun??o de compreender o exerc?cio profissional no seu ambiente institucional, considerando o assistente social na condi??o de trabalhador assalariado e, a partir desta an?lise, compreender os perfis pedag?gicos dos assistentes sociais constru?dos em seu entorno. A pesquisa n?o teve a inten??o de apontar modelos de perfis pedag?gicos, mas de apreender as tend?ncias na profiss?o nesses espa?os pedag?gicos, a fim de fomentar o debate sobre a dimens?o pol?tica/ideol?gica e educativa da profiss?o e do exerc?cio profissional na educa??o em Natal/RN. Logo, foram apreendidas e analisadas via entrevista semi-aberta, que identificaram diversas tend?ncias dos perfis pedag?gicos caracterizados como de ajuda, participa??o e de emancipa??o , de acordo com as condi??es institucionais, conjunturais e do pr?prio direcionamento profissional do assistente social, como tamb?m, na materializa??o do projeto ?tico/pol?tico da profiss?o. Ratifica-os, ent?o, como um elemento importante de compreens?o do exerc?cio profissional do assistente social na educa??o e como um espa?o rico de an?lise dos perfis pedag?gicos do assistente social no fomento a produ??o acad?mica acerca do trabalho do assistente social na educa??o
