The research aimed to investigate how the graduated students from Tourism Course with emphasis in hotel, realized the role of their Course in their professional lives. The quantity-qualitative research involved 48 graduated students. The data were collected from a questionnaire with opened and closed questions. Concerning to the results, the search brought important information to a reflexive auto-evaluation process as: while students, the majority of them had expectations about the insertion of this professional in the tourism area, and nowadays, half of them are out of their professional area; only 33,3% declared absolutely satisfied with the course; in suggesting changes to improve the Course, the focus was in practical activities, apparently trying to translate a technician view of the Pedagogical Politic Project of the Course. Concluding, the dialogue with the graduated students was essential to renew the thought of the Course staff bringing challenge questions. / Esta dissertação é resultado de pesquisa desenvolvida no Programa de Mestrado em Educação, linha de pesquisa 2 Formação e Prática Pedagógica do Profissional Docente, da Universidade do Oeste Paulista. A pesquisa teve como objetivo investigar a forma como os egressos do Curso de Turismo da Unoeste percebem o papel que o curso desempenhou na sua formação profissional. A pesquisa caracterizou-se como quanti-qualitativa, envolvendo 48 egressos do curso de Turismo, com ênfase em Hotelaria, da Unoeste. Para a coleta de dados recorreu-se a um questionário com perguntas fechadas e com perguntas abertas. Em relação aos resultados, a pesquisa trouxe importantes informações para o processo reflexivo de autoavaliação, por exemplo: enquanto eram alunos, a maioria nutria expectativa da inserção do profissional na área de turismo; hoje, como egressos, a metade está fora da área do bacharelado; apenas 33,3% dos egressos manifestaram-se como plenamente satisfeitos com o curso. Ao sugerirem mudanças para melhorar o curso, o foco foi em atividades práticas, parecendo traduzir uma visão tecnicista do Projeto Político Pedagógico do curso. Concluindo, o diálogo com os egressos é fundamental para a renovação das linhas de pensamento do curso, trazendo perguntas desafiadoras.

Au cours d'une infection lytique, le virus de l'herpès simplex de type 1 (VHS-1) doit entreprendre plusieurs étapes de fusion afin de se répliquer et se propager correctement. Ainsi, le virus a évolué afin de tirer avantage de la machinerie cellulaire en utilisant des protéines et facteurs de l’hôte à cet effet. Dans la littérature, les processus sous-jacents à l’entrée du VHS-1 ont été largement élucidés. Cependant, on ne sait toujours pas comment les particules virales nouvellement synthétisées sortent de la cellule hôte et quels facteurs cellulaires sont impliqués dans ce processus. Des résultats publiés par notre laboratoire indiquent que la protéine cellulaire, Extended Synaptotagmin 1 (E-Syt1), a un impact négatif sur la propagation globale du virus lorsqu’inhibée par de l’ARN d’interférence. Conséquemment, la présente étude a pour objectif de confirmer et d'approfondir le rôle d’E-Syt1 sur la propagation virale, en particulier sur la sortie du virus. Étant donné que l’activation d’E-Syt1 est liée à l’augmentation de la concentration de calcium cytoplasmique, nous avons également étudié l'implication du calcium au cours des stades ultérieurs de la réplication virale. Ici, nous avons démontré que la surexpression d’E-Syt1 n’a pas d’effet détectable sur la sortie du VHS-1, mais que le calcium a effet sur la propagation virale. Alors que la séquestration précoce du calcium (4 et 6 heures post-infection) à l'aide de chélateurs réprime la sortie virale, aucun effet significatif a été détecté lorsque les chélateurs ont été ajoutés à un stade avancé de l’infection (12 et 16 heures post-infection). Nos résultats fournissent des données intéressantes sur la nécessité de l’homéostasie du calcium intracellulaire afin que VHS-1 puisse assurer une médiation adéquate de la sortie virale. Ces résultats pourraient conduire à la découverte de nouveaux mécanismes ou protéines cellulaires régulées par le calcium et utilisés par le VHS-1 lors de réplications lytiques virales. / During a lytic infection, Herpes Simplex Virus type 1 (HSV-1) must go through multiple steps of fusion to replicate and propagate properly. For this purpose, the virus has evolved consequently by taking advantage of the cellular machinery using host factors and proteins. In the literature, processes underlying HSV-1’s entry have been extensively elucidated. However, it remains unclear how newly synthesized viral particles egress from the host cell, and what cellular factors are implicated in this process. Results published by our laboratory suggest that the cellular protein, Extended Synaptotagmin 1 (E-Syt1), has a negative and global impact on the viral propagation when down regulated by RNA interference. Consequently, this study aims to confirm and deepen our understanding of E-Syt1’s role on HSV-1, particularly during viral egress. Since activation of E-Syt1 is linked to the increase in cytoplasmic calcium concentration, we also investigated calcium involvement during later stages of viral propagation. Interestingly, overexpression of E-Syt1 had no measurable effect on HSV-1 propagation whereas calcium has a dual effect on viral propagation. While early calcium sequestering (4 and 6 hours post-infection) using chelators represses viral egress, no significant effect was detected when chelators were added at later time points (12 and 16 hours post-infection). Our results give interesting insights on how HSV-1 relies on intracellular calcium homeostasis to properly mediate viral egress. These results may lead to the discovery of new mechanisms or cellular proteins that are regulated by calcium and hijacked by HSV-1 during lytic replication.

Die Bildung infektiöser Viruspartikel des humanen Zytomegalievirus (HCMV) ist ein mehr-stufiger Prozess. Sie beginnt mit der Verpackung der DNA in die Kapside im Kern, gefolgt von weiterer Reifung während des Transports durch das Zytoplasma und der abschließenden Freisetzung aus der Zelle. Im Zuge dieser Arbeit wurden zwei Proteine, die Einfluss auf die ebengenannten Prozesse haben, analysiert. Der erste Teil der Arbeit befasst sich mit der funktionellen Charakterisierung des HCMV Pro-teins pUL77. Es ist bekannt, dass das homologe Protein pUL25 in alpha-Herpesvirinae essentiell für die DNA-Verpackung ist. Zunächst konnte das Protein als Kapsid-assoziiertes strukturelles Protein identifiziert werden. Es wurden Interaktionen von pUL77 mit DNA-Verpackungs- und Kapsidproteinen gezeigt. Weiterhin wurde die DNA-Bindungsfähigkeit von pUL77 in verschiedenen „in vitro“-Experimenten untersucht. Zusammengefasst weisen unsere Ergebnisse auf eine Funktion von HCMV pUL77 bei der DNA-Verpackung hin. Im zweiten Teil der Arbeit wurde das HCMV Protein pUL71 charakterisiert, das in allen Herpesviren konserviert vorkommt, dessen Funktion jedoch nicht charakterisiert ist. Zunächst wurde das Protein als strukturelles Tegumentprotein mit “earlylate“ Expressionskinetik klassifiziert. Weiterhin wurden die subzelluläre Lokalisation sowie virale und zelluläre Interaktionspartner untersucht. Die Ergebnisse weisen auf eine Funktion von HCMV pUL71 bei der Reifung und beim Transport der Virionen im Zytoplasma hin. „In silico“-Vorhersagen zeigten ein „Leuzin Zipper“-Motiv in pUL71, das als mögliche Oligomerisationsdomäne dienen könnte. Mutationen wurden in dieses Motiv eingebracht und die resultierenden Proteine auf ihre Oligomerisationsfähigkeit mit „in vitro“-Methoden und in rekombinanten Viren untersucht. Zusammenfassend konnten wir zeigen, dass das „Leuzin Zipper“-Motiv wichtig für die Funktion von pUL71 ist und diese mit einer unbeeinträchtigten Oligomerisation des Proteins zusammen hängt. / The morphogenesis of Human cytomegalovirus (HCMV) virions starts with the capsid assem-bly and DNA insertion in the nucleus followed by maturation during transport through the cytoplasm prior to release of virus progeny. In this study we are functionally characterising two proteins that are involved in those steps. The function of essential HCMV protein pUL77 is characterised in the first part of the study. HCMV pUL77 was shown to be a structural protein associated with capsids. Furthermore, our experiments demonstrated that HCMV pUL77 interacts with DNA packaging motor compo-nents and capsid proteins. The ability of HCMV pUL77 to bind double-stranded DNA was studied in “in vitro” assays designed for this study. The homologue α-Herpesvirinae protein pUL25 is described to be involved in processes connected with DNA packaging. Data ob-tained in this study demonstrates that HCMV pUL77 might serve a similar function. In the second part of the study HCMV pUL71, conserved throughout the Herpesvirus family but to date unclassified, was functionally characterised. HCMV pUL71 was defined a struc-tural tegument protein with early-late expression kinetics. We studied the sub-cellular local-isation and interactions of pUL71 with a subset of cellular and viral proteins. Thereby we could show that HCMV pUL71 function might be connected with processes of viral egress. By in silico analyses we identified a leucine zipper motif in pUL71 that might serve as a puta-tive oligomerisation domain. In order to investigate the function of the leucine zipper motif, we performed in vitro assays and investigated the alterations of the motif in the viral context. Taken together we can conclude that (i) an intact leucine zipper motif is crucial for the func-tion of pUL71 and (ii) this function is dependent upon undisturbed oligomerisation of the pro-tein.

It offers subsidies to perceive the organizations of this social type as an option of politics in attention to those. For in such a way, a study of case was carried through in the Mixing Cooperative of Workers João de Barro COOTRAJOBA, situated in the city of Pedro Osório/RS. The detailing concerning its reality, makes possible the reflection on the historical contradictions between free society and prisional universe, pointing out the egress in the historical process of prison overloads , also displaying the selective logic of the punitive system currently adopted in Brazil. It analyzes the corporate logic and its politics and socioeconomics transformations as linked to the transformations of punitive models, centered in the world of the work, as well as the directions attributed to this. It evidences the decisive paper that COOTRAJOBA occupies in the return to the life in freedom of its partner, as being the only form of income and confers to that one a new identity. It promotes elements of autonomy and self management from the new way with that the partners if relate with the work, but does not obtain to promote access to the Social Rights and to supply current necessities of the same ones. It is argued then, the implications that hinder the movements capable to promote overcoming of stigmata and access to the Social Rights / A presente dissertação centra-se no estudo do cooperativismo como uma alternativa aos egressos do Sistema Prisional. Oferece subsídios para perceber as organizações desse tipo social como uma opção de políticas em atenção àqueles. Para tanto, foi realizado um estudo de caso na Cooperativa Mista de Trabalhadores João de Barro COOTRAJOBA, situada no município de Pedro Osório/RS. O detalhamento acerca de sua realidade possibilita a reflexão sobre as contradições históricas entre sociedade livre e universo prisional, situando o egresso no processo histórico de sobrecargas prisionais, além de expor a lógica seletiva do sistema punitivo adotado atualmente no Brasil. Analisa a lógica societária e suas transformações políticas e socioeconômicas como atreladas às transformações de modelos punitivos, centradas no mundo do trabalho, bem como os sentidos atribuídos a este. Evidencia o papel decisivo que a COOTRAJOBA ocupa no retorno à vida em liberdade de seu sócio, como sendo a única forma de renda e confere àquele uma nova identidade. Promove elementos de autonomia e autogestão a partir da nova maneira com que os sócios se relacionam com o trabalho, mas não consegue promover acesso aos Direitos Sociais e suprir necessidades atuais dos mesmos. Discutem-se, então, as implicações que obstaculizam os movimentos capazes de promover superação de estigmas e acesso aos Direitos Sociais

The purpose of the research, therefore, was to demonstrate the profile of 54 men who served the sentence at PIG and benefited withthe remission through the study, which was a result of a clash of data obtained from the documents of Pro-egress Program in Guarapuava, CEEBJA Nova Visão and PIG. It is essentially a descriptive and bibliographic study. The current work was divided into three chapters. In the first, we tried to clarify the figure of the State, its relation with Law, its evolution together with criminal law, its sentences and its purposes, as well as how it focuses on the existing relation between the State and the power to punish, where it was established the existence of so called “enemies”. Also, at the moment, as well as along the research, criticisms toward the state and the capitalism were presented, which ended up influencing sentences evolution and aided in the origin of penitentiaries. The second chapter deals with the institution of remission, its modalities and, mainly focused on the remission through the studies, carrying out a critical analysis on its actual purposes. Finally, in the third chapter, it was evidenced the socioeconomic profile and the schooling level of the egressed individual from the Industrial Penitentiary inGuarapuava, which remitted sentences through the studies, characterizing then the Industrial PenitentiaryinGuarapuava, the educational system provided in the location as well as the experience in the court of criminal enforcement in Guarapuava. The theoretical contribution was based on official documents and on scientific production of intellectuals and researchers, standing out Bitencourt, Baratta, Leal, Guimarães, Costa, Paduanni, among others. It was evidenced that the egress from PIG, despite serving service in an establishment which follows the law, does not have a profile that distinguishes it from the standard in the state of Paraná. Moreover, we verified that PIG cannot be considered as exemplary, but as acountertrend. / O presente trabalho tem como objeto de pesquisa a figura da remição pelo estudo e, com o objetivo geral, buscou-se evidenciar o perfil do egresso da Penitenciária Industrial de Guarapuava, que optou por remir pena pela educação, sua situação socioeconômica e educacional, tendo como recorte temporal aquele que se tornou egresso entre o período de janeiro do ano de 2010 a dezembro do ano de 2011. O problema da pesquisa, portanto, foi o de demonstrar qual é o perfil dos 54 homens que cumpriram pena na PIG e beneficiaram-se com a remição pelos estudos, número este conseqüência do embate de dados adquiridos nos documentos do Programa Pró-egresso de Guarapuava, CEEBJA Nova Visão e PIG. Trata-se de pesquisa essencialmente descritiva e bibliográfica. O presente trabalho foi dividido em três capítulos. No primeiro buscou-se demonstrar a figura do Estado, sua relação com o Direito, sua evolução conjuntamente ao Direito Penal, as penas e suas finalidades, bem como focalizou a relação existente entre o Estado e o poder de punir, onde se verificou a existência dos chamados “inimigos”. Também, neste momento, bem como ao longo de toda a pesquisa, apresentou críticas a respeito do Estado e do capitalismo, que acabaram por influenciar a própria evolução das penas e auxiliaram na origem das penitenciárias. O segundo capítulo abordou o instituto da remição, suas modalidades e, principalmente focalizou-se a remição pelo estudo, realizando abordando suas reais finalidades. Finalmente, no terceiro capítulo, evidenciou-se o perfil socioeconômico e nível de instrução escolar do egresso da Penitenciária Industrial de Guarapuava que remiu pena pelos estudos, caracterizando-se a Penitenciária Industrial de Guarapuava, o sistema educacional lá fornecido bem como a experiência da Vara de Execução Penal de Guarapuava. O aporte teórico foi embasado em documentos oficiais e na produção científica de intelectuais e pesquisadores, destacando-se Bitencourt, Baratta, Leal, Guimarães, Costa, Paduanni, dentre outros. Evidenciou-se que o egresso da PIG, apesar de cumprir pena em estabelecimento que segue a Lei, possui perfil que não difere do comum no Estado do Paraná. Além disso, verificou-se que a PIG não pode ser considerada como modelo, mas sim, uma contratendência.

The research was based on the methodology of qualitative research, and data collection through semi-structured individual interviews, conducted in an unsystematic way. The life trajectory of each participant and each respondent was professional, chronologically organized on the basis of six chapters. From this organization information could be identified the route that prison graduates on the streets run until the homeless and also who are the potential professionals who serve this directly or indirectly public. In the first chapter to try to better understand who the prison egress on the streets, we prioritize making a preliminary analysis of the Brazilian situation to try to understand that society is such that there is prison egress in the streets. In the second chapter we analyze the data on the current Brazilian prison system: number of incarcerated people and number of employees to meet this demand; overcrowding in prisons - an x-ray of the prison system; They are seen as prisoners; family ties of prisoners, difficulties and conditions imposed for visits and for the last if it happens or not the rehabilitation of prisoners. In the third chapter we discuss the situation of the prison egress from the Brazilian legislation, as they are seen by society, but also on family ties after their return from imprisonment. As well as the requirements and compliance with the obligations established by the Penal Execution Law. In the fourth chapter we seek to point out the difficulties people living on the streets suffer (not just limiting condition prison egress), addressing the fragility of family ties, unemployment and few job alternatives. In chapter five we analyze the tract of public policies of social welfare, public health and public safety in the prison egress in the streets. In the final chapter we analyze all nine interviews with adult men and women, aged 21 ~ 64 years, served in various departments of the state of São Paulo. Analyzing the collected answers about: life in prison; reality as prison egress; the preparation for the return to freedom; the determinations of LEP to prison egress; life in freedom after the arrest; living on the street; the relationship to work; documentation; financial situation; the question of survival; prejudice for being prison egress; challenges; the relationship with family; Public support services. We also analyzed twelve interviews with various professionals that serve this population from the time of incarceration to the streets / Esta dissertação enfatiza a condição de vida do egresso prisional em situação de rua no Estado de São Paulo. A investigação foi realizada com base na metodologia de uma pesquisa qualitativa, e coleta de dados, por meio de entrevistas individuais semi-estruturadas, conduzidas de maneira assistemática. A trajetória de vida de cada participante e de cada profissional entrevistado foi, cronologicamente, organizada com base nos seis capítulos. A partir dessa organização de informações foi possível identificar o percurso que os egressos prisionais em situação de rua percorrem até ficar em situação de rua e também quem são os possíveis profissionais que atendem esse público direta ou indiretamente. No primeiro capítulo para tentarmos entender melhor quem é o egresso prisional em situação de rua, priorizamos efetuar uma analise preliminar sobre a conjuntura brasileira para tentar entender que sociedade é essa que existe egresso prisional em situação de rua. No segundo capítulo analisamos os dados sobre o sistema prisional brasileiro atual: número de pessoas encarceradas e número de funcionários para atender a essa demanda; a superlotação nas prisões um raio-x do sistema prisional; como são vistas as pessoas presas; os vínculos familiares dos presos, dificuldades e condições impostas para visitas e por último pontuar se acontece ou não a ressocialização dos presos. No terceiro capítulo abordamos a situação do egresso prisional, desde a legislação brasileira, como são vistos pela sociedade, como também sobre os vínculos familiares após seu retorno do encarceramento. Assim como as exigências e o cumprimento das obrigações estabelecidas pela Lei de Execução Penal. No quarto capítulo buscamos apontar as dificuldades que as pessoas em situação de rua sofrem (não limitando apenas a condição de egresso prisional), abordando a fragilidade dos vínculos familiares, o desemprego e as escassas alternativas existentes de trabalho. No capítulo cinco analisamos o trato das políticas públicas da assistência social, saúde pública e de segurança pública com o egresso prisional em situação de rua. Já no último capítulo analisamos todas as nove entrevistas com homens e mulheres adultos, na faixa etária de 21 ~ 64 anos, atendidos em diversos serviços do estado de São Paulo. Analisando as respostas colhidas sobre: a vida na prisão; a realidade como egresso prisional; a preparação para o retorno à liberdade; as determinações da LEP para o egresso prisional; a vida em liberdade após a prisão; o morar na rua; a relação com o trabalho; documentação; situação financeira; a questão da sobrevivência; o preconceito por ser egresso prisional; os desafios; a relação com a família; os serviços públicos de apoio. Analisamos também doze entrevistas com diversos profissionais que atendem essa população desde o momento do encarceramento até a situação de rua

L’objectif de cette thèse est de proposer un modèle comportemental de l’être humain pour la simulation d’évacuation de bâtiment en cas d’incendie et de l’intégrer dans un outil de simulation d’évacuation de bâtiment. Le modèle proposé représente une approche individu-centré du comportement et répond aux axiomes de la Rationalité Limitée énoncés par Herbert Simon grâce à une conception hiérarchique des moyens cognitifs des agents simulés. L’implémentation du modèle du comportement présente la particularité d’être intégralement réalisée en GPU (via OpenGL 2.0). Ainsi la fréquence du moteur de comportement est très proche de celle du simulateur et permet une adaptation quasi temps réel des comportements des agents à un changement de perception de leur environnement. Le logiciel d’évacuation développé permet :– l’importation de scénario d’incendie de bâtiment simulé grâce au logiciel FDS,– la configuration des archétypes de comportement des agents évacuant, notamment :– la description des hypothèses sur le monde (connaissance individuelle),– la configuration des comportements des agents (moyens cognitifs individuels).– le positionnement des agents dans le bâtiment,– la simulation de l’évacuation,– l’enregistrement et le play-back d’un scénario d’évacuation.Les contraintes (feu, fumée, obstacles, autres agents) captées par un agent sont interprétées par ce dernier en fonction de son archétype de comportement afin de déterminer si sa stratégie d’évacuation doit être remise en cause. / The main objective of this thesis is to propose a behavioral model of the human being in presence of several constraints and to integrate it into a simulation tool for building egress. The proposed model represents an individual-based approach of behavior modelisation and implement axioms of the bounded rationality set by Herbert Simon providing two key features :– individual prioritization and parametisation of cognitivemeans,– individual perception and knowledgemanagement.The proposed software has the particularity to run entirely on GPU via OpenGL 2.0. Thus the frequency of the behavior engine is very near to that of the simulator and allow adaptation of near real-time behavior of agents in a changing perception of their environment.

The existing simulators require fully-modeled 3D environments and enough time to prepare and simulate scenarios. Since the amount of people in a given simulated scenario can change over time, several simulations are often required in order to generate an optimal evacuation plan. With that in mind, we present in this paper a novel approach to estimate the resulting data of a given evacuation scenario without actually simulating it. For such, we divide the environment into modular rooms with different configurations, in a divide-and-conquer fashion. Next, we train an artificial neural network to estimate all required data regarding the evacuation of a single room. After collecting the estimated data from each room, we developed a heuristic capable of aggregating per room information so the full environment can be properly evaluated. Our method presents errors within the 30% margin when compared to evacuation time in a real and complex environment. In addition, it is not necessary to model the 3D environment, learn how to use and configure a crowd simulator, and the computational time to estimate is instantaneous when compared to a best case real-time crowd simulator.

The research premise is that the policy of interiorization and expansion of professional and technology education, by decentralizing opportunities, create a differential for the educational and professional trajectory of part of the graduates. This training, however, retain a relative connection with the productive potentialities in the coverage territories. This study includes a review of the literature on education and labor market and a discussion about the role of technical and professional formation for the local development versus the logic of the free market, considering the expansion of public spending for this purpose. For this study two sets of information and data have been collected primarily, with qualitative and quantitative nature. The research with qualitative focus, entitled Pesquisa de Avalia??o da Expans?o (PAEX), is constituted by series of open interviews applied to institutional representatives, with the purpose of knowing aspects of the interiorization repercussion in the local development process. The research designed to quantity analysis, entitled of the Pesquisa de Acompanhamento de Egressos (PAE), have been put in practice by applying online questionnaire with closed questions to IFRN s former students, aiming to know the form of insertion of the graduates in the labor market and the formation capacity of increasing the welfare, among other things. Empirical data and information fully confirmed the hypothesis of this study, for they really demonstrated that the expansion policy decentralizes opportunities and constitutes an important differential for the professional trajectory of a significant portion of the graduates. However, the graduates employability in the labor market in their territories of coverage is below expectations, due to structural problems of the local economy related to scarcity of jobs, difficulty in wage growth and in professional development. Complementarily, it has been observed institutional difficulties related to the recent implantation process of the policy of professional and technical education in the various campuses of the Institution / O presente estudo tem como prop?sito analisar em que medida o processo de interioriza??o do IFRN contribui para a endogeneiza??o do desenvolvimento local e territorial, mais precisamente em termos da absor??o de egressos no mercado de trabalho, forma de inser??o e melhoria da renda e qualidade de vida. A hip?tese de pesquisa ? a de que a pol?tica de interioriza??o e expans?o da educa??o profissional e tecnol?gica, ao descentralizar oportunidades, permite um diferencial para a vida educacional e profissional de parcela dos alunos formados, entretanto, a forma??o mant?m uma conex?o relativa com as potencialidades produtivas nos territ?rios de abrang?ncia. A revis?o bibliogr?fica centrou-se na literatura sobre educa??o e mercado de trabalho, bem como na discuss?o do papel da forma??o t?cnica e profissional para o desenvolvimento local, em contraposi??o ? l?gica de mercado, tendo em vista a amplia??o do gasto p?blico para este fim. Para este estudo foi feita a coleta prim?ria de dois conjuntos de informa??es e dados, simultaneamente, de natureza qualitativa e quantitativa. A pesquisa de enfoque qualitativo, intitulada Pesquisa de Avalia??o da Expans?o (PAEX), constituiu-se numa s?rie de entrevistas abertas destinadas a representantes institucionais, visando conhecer aspectos da repercuss?o da interioriza??o da Institui??o no processo de desenvolvimento local. A pesquisa com tratamento quantitativo, intitulada Pesquisa de Acompanhamento de Egressos (PAE), foi realizada mediante a aplica??o de question?rio online, com perguntas fechadas, destinadas aos ex-alunos do IFRN, objetivando definir o perfil da inser??o no mercado de trabalho e a capacidade da forma??o de alterar a qualidade de vida do ex-aluno, entre outros aspectos. Os resultados confirmam plenamente a hip?tese do estudo, ao demonstrar que, de fato, a pol?tica de interioriza??o descentraliza oportunidades e se constitui num diferencial importante para a maioria dos egressos. Por?m, a absor??o destes no mercado de trabalho dos respectivos territ?rios de abrang?ncia se mostra aqu?m das expectativas, em virtude de problemas estruturais da economia local, que favorecem a escassez de oportunidades de trabalho e dificuldades relacionadas ao crescimento e valoriza??o profissional. Al?m disto, se constatou dificuldades institucionais relacionadas ao recente processo de implanta??o da pol?tica de educa??o profissional e tecnol?gica em v?rios campi da Institui??o
