O foco deste estudo incide, especialmente, sobre a gestão escolar em três escolas de Educação Básica da Rede Municipal de Ensino de Florianópolis que receberam transferência direta de recursos financeiros pelo Fundo Nacional de Desenvolvimento da Educação, via PDE Interativo, entre 2012 e 2013. Como objetivos específicos, buscou-se compreender as propostas e intencionalidades do MEC em relação ao PDE Interativo; conhecer como as escolas têm gerenciado esse programa educacional a partir das ações e metas por ele propostas. Adotamos procedimentos sistemáticos de coleta de dados por meio de entrevistas com participantes de escolas e Secretaria Municipal de Educação envolvidos com o Plano. A análise documental abrangeu relatórios e manuais do governo federal que expressam essa política, como também livros e relatórios do Banco Mundial (BM) e da Unesco que tratam da temática, além dos planos de ação de cada escola participante. Para desenvolver essa pesquisa de abordagem qualitativa, nos fundamentamos no materialismo histórico e dialético construindo as análises a partir das categorias de totalidade, contradição e mediação. O PDE Interativo monitora as ações selecionadas pela equipe diretiva no planejamento estratégico, alterando as formas de financiamento e gestão da educação. Isso implica que todos os dados e informações coletados, via planejamento estratégico, podem servir à formulação de novas políticas públicas com fins de otimizar os gastos públicos com educação. Ao mesmo tempo, o PDE Interativo se configura como uma política educacional de accountability, ou seja, de responsabilização dos docentes pelos resultados da escola. O PDE Interativo é expressão da gestão centrada na escola, que tem nos princípios da eficácia e da racionalização os elementos essenciais da gestão escolar proposta pelo BM. Este modelo consiste na estratégia de descentralizar a tomada de decisões ao nível local das escolas, envolvendo a participação de pais, professores, alunos e a comunidade. Destarte, compreendemos que esta política educacional aponta para a descentralização da gestão educacional ao âmbito local da escola, ao mesmo tempo em que recentraliza informações, em nível de órgão central, MEC. Apesar de pouco afetarem os indicadores educacionais, esse movimento de centralização-descentralização provoca mudanças substanciais na organização e funcionamento das escolas, mostrando ser a gestão, e não a qualidade da educação, seu objeto maior.<br> / Abstract : The Interactive School Development Plan of school is a public politics constituted by intersectoral and educational action and programs. It is presented as a support tool to school management elaborated by Ministry of Education (MEC) in partnership with the education secretaries. This paper focuses on the school management in three Basic Education schools in Florianópolis Municipal Education System which received direct transfer of financial resources from the National Funds of Education Development, via Interactive School Development Plan, from of 2012 to 2013. Specific objectives are to explain the Interactive School Development Plan proposals and the MEC?s intention related to this plan and to study on how schools have been managing this educational program concerning its proposed actions and goals. We adopted systematic procedures of data collection by interviewing school participants and Municipal Education secretaries involved in the Plan. The Documental analysis comprehended reports and manuals from the federal government which express this policy, as well as books and reports from the World Bank and UNESCO that approach the theme, and action plans of each participant school. To develop this qualitative research, we are grounded on dialectic and historical materialism, building the analysis from the categories of totality, contradiction and mediation. The Interactive School Development Plan monitors the actions selected by the management team on the strategic planning, modifying educational funding and management. This implicates that all information and data collected, via strategic planning, can be used to phrase new public politics aiming the optimization of public expenses on education. At the same time, Interactive School Development Plan is an accountability educational politics, which means it holds docents liable to schools results. Interactive School Development Plan is the expression of school based management which has in the efficacy and rationalization principles the essential elements of the school management proposed by the World Bank. This model consists in the strategy of decentralize the decision making to the school local levels, involving parents, teachers, students and community participation. We understand, thus, that this educational politics points to a decentralization of educational management to the school local level, while it simultaneously recentralize information, in central organ level, MEC. Although its little impact on educational indicators, this centralization-decentralization movement provokes substantial changes in schools organization and functioning, revealing the management  not the education quality  as its main goal.

A tarefa de classificar é caracterizada pela associação de rótulos de classes a documentos com o objetivo de criar agrupamentos semânticos. O aumento exponencial no número de documentos e dados digitais demanda formas mais precisas, abrangentes e eficientes para busca e organização de informações. Nesse contexto, o aprimoramento de técnicas de classificação de documentos com o uso de informação semântica é considerado essencial. Sendo assim, este trabalho propõe uma abordagem baseada em conhecimento para a classificação de documentos. A técnica utiliza termos extraídos de documentos associando-os a conceitos de uma base de conhecimento de domínio aberto. Em seguida, os conceitos são generalizados a um nível maior de abstração. Por fim, é calculado um valor de disparidade entre os conceitos generalizados e o documento, sendo o conceito de menor disparidade considerado como rótulo de classe aplicável ao documento. A aplicação da técnica proposta oferece vantagens sobre os métodos convencionais como a ausência da necessidade de treinamento, a oportunidade de atribuir uma ou múltiplas classes a um documento e a capacidade de aplicação em diferentes temas de classificação sem a necessidade de alterar o classificador.<br> / Abstract : Document classification provides a way to organize information, providing a better way to understand available data. The classification task is characterized by the association of class labels to documents, aiming to create semantic clusters. The exponential increase in the number of documents and digital data demands for more precise, comprehensive and efficient ways to search and organize information. In this context, the improvement of document classification techniques using semantic information is considered essential. Thus, this paper proposes a knowledge-based approach for the classification of documents. The technique uses terms extracted from documents in association with concepts of an open domain knowledge base. Then, the concepts are generalized to a higher level of abstraction. Finally a disparity value between generalized concepts and the document is calculated, and the best ranked concept is then considered as a class label applicable to the document. The application of the proposed technique offers advantages over conventional methods including no need for training, the choice to assign one or multiple classes to a document and the capacity to classify over different subjects without the need to change the classifier.

Le cancer colorectal (CCR) est une pathologie dont les causes tiennent en partie d’un style de vie basé sur un régime alimentaire de type occidental et un mode de vie sédentaire. Cela implique par conséquent que le CCR soit associé à d’autres troubles métaboliques tels que l’obésité et le diabète. D’un consensus général on considère que le CCR est une maladie qui est mieux traitée si elle est dépistée relativement tôt ; malheureusement il n’existe toujours pas d’outils de diagnostic suffisamment fiables. A ce propos, différents types de glycosylation ont été proposés comme de potentiels biomarqueurs de cette maladie. Les travaux abordés dans cette thèse ont concerné l'influence de la O-GlcNAcylation (consistant en le transfert d'un seul monosaccharide de N-acétylglucosamine sur des résidus de sérine/thréonine de protéines cytoplasmiques, nucléaires et mitochondriales), sur la glycosylation complexe dans des lignées cellulaires coliques (HT29, HCT116 et CCD841CoN). La O-GlcNAcylation est intimement liée au statut nutritionnel, il est d’ailleurs proposé que son niveau soit plus élevé dans les pathologies métaboliques. Néanmoins il est clairement montré que les cellules et les tumeurs coliques expriment des niveaux plus élevés de O-GlcNAcylation. Plusieurs études ont montré que l’inhibition ou la délétion de la O-GlcNAc transférase (OGT), l’enzyme responsable des processus de O-GlcNAcylation, réduisait l'agressivité ou les propriétés associées au caractère tumoral dans différents modèles de cancer. Quelques études ont également montré que la sous-régulation de l’OGT se répercutait sur les glycosylations complexes : N- et O-glycanes, et glycosphingolipides (GSLs). La O-GlcNAcylation participe à des processus cellulaires clés tels que la transcription et la traduction. Dans une étude préliminaire, nous avons examiné les niveaux de transcrits de quatre-vingt-six glycosyltransférases et glycosidases dans des conditions de siOGT. Le siOGT a permis de constater que plusieurs de ces gènes étaient régulés positivement ou négativement, bien que parmi ces gènes seuls 10 étaient régulés négativement de manière significative. L'influence de l’OGT sur l’expression protéique de plusieurs glycosyltransférases a également été explorée. Nous avons ensuite utilisé plusieurs lectines en microscopie par fluorescence et en cytométrie en flux ainsi que la spectrométrie de masse (glycomique) afin d'élucider les structures complexes des glycanes et leur niveau d’expression dans les cellules coliques traitées par des siOGT. La diminution de O-GlcNAcylation n'a eu qu’un effet modéré sur les N- et O-glycanes globaux. Cependant, l'expression de plusieurs antigènes de surface a été modifiée par le siOGT. La E-cadhérine, un facteur majeur de la transition épithéliale-mésenchymateuse, a été régulée positivement dans les cellules HT29 traitées par le siOGT. De plus, les glycanes complexes portés par la E-cadhérine ont été eux-mêmes modifiés dans les cellules traitées par le siOGT. L'analyse MALDI des GSLs extraits de cellules HCT116 a révélé une altération significative de ces derniers dans les cellules siOGT, inversant le patron d’expression des GSLs décrits dans certaines cellules cancéreuses. Les GSLs des séries Globo, Gb3 et Gb4 ont été régulés à la hausse, tandis que les GSL gangliosidiques GM1a, GM2 et GD1a ont été régulés à la baisse. Cette étude démontre pour la toute première fois une relation entre la O-GlcNAcylation et les GSLs. Étant donné que les GSLs jouent un rôle important dans la reconnaissance cellulaire, la transduction du signal et d'autres propriétés de la surface cellulaire, ces observations pourraient expliquer en partir les changements phénotypiques liés au siOGT. De manière générale, une diminution de l’α2,3-sialylation est observée dans des conditions siOGT. Ces travaux sont les premiers à montrer un effet de la déplétion en OGT sur l’ensemble du glycome complexe, en particulier ceux s’exprimant à la surface des cellules. / Colorectal cancer (CRC) remains a major cause of health burden in Europe and in the western world. It is a disease of lifestyle with the western diet and a sedentary lifestyle widely implicated. This implicates CRC to be associated with other metabolic disorders like obesity and diabetes. The general consensus is that it is a disease that is hugely avoidable and treatable if detected early however reliable detection tools are still lacking. Glycosylation biomarkers have been proposed as potentially a new frontier against this disease. The work covered in this thesis pertains to the influence of O-GlcNAcylation (the transfer of a single N-acetyl glucosamine monosaccharide on serine/ threonine residues), on complex glycosylations in colon cells (HT29, HCT116 and CCD841CoN). O-GlcNAcylation is a nutrient sensor which conveys the metabolic state and indeed is aberrantly regulated in metabolic disease. CRC cells and tissues express higher levels of O-GlcNAcylation and an accompanying phenotype of high proliferation and aggressive tumours. There are numerous studies showing that silencing O-linked N-acetylglucosamine transferase (OGT), the enzyme that catalyses O-GlcNAcylation, decreases the aggressiveness or cancer-like properties in several cancer models. There is little evidence starting to accumulate that shows that in these siOGT cells or tissue there is also a change in other complex glycosylations (N-, O- or glycosphingolipids glycans). O-GlcNAcylation is known to participate in key cell processes like transcription and translation. In this preliminary work, we look at the transcriptomic expression of eighty-six glycosyl transferases and glycosidases gene transcripts when OGT is silenced. Silencing OGT resulted in several of these genes being upregulated or downregulated but only 10 genes were significantly downregulated. The translational influence of OGT on several glycosyl transferases was also explored. We used several techniques namely; fluorescent lectin microscopy, lectin aided FACS analysis and several mass spectrometry techniques (glycomics), to study the complex glycan structures and expression in siOGT colon cells. Silencing O-GlcNAcylation has little effect on the global N- and O-glycans as elucidated by glycomic profiling. However, cell surface expression of several glyco-antigens was altered in siOGT. E-cadherin, a major influencer of the epithelial-to-mesenchymal transition, is upregulated in siOGT transfected HT29 cells. Furthermore, the complex glycans it carries are altered in the process. This could in part explain some of the siOGT phenotypes noted in other studies. Using MALDI mass spectrometry analysis, in HCT116 cells we found that glycosphinogolipid (GSL) expression is altered significantly in siOGT HCT116 cells. There is a reversal of some known cancerous GSL patterns; Globo series, Gb3 and Gb4 GSLs were upregulated, while ganglioside GSLs GM1a, GM2 and GD1a are downregulated. This is the first time an association has been made between O-GlcNAcylation and GSLs. As GSLs play an important part in cell recognition, signal transduction and other cell surface properties this may be one of the key links with the siOGT phenotype. All together there is a decrease in several α2,3-sialylated glycans when OGT is silenced. For the first time in scientific literature we show the global glycan effect of silencing OGT on the expression of complex glycans particularly at the cell surface, adding several new findings.

Thesis advisor: Jia Niu / O-linked β-N-acetylglucosamine (O-GlcNAc) is a post-translational modification plays important roles in cellular network/diseases such as autophagy, transcriptional activity, protein stability, phosphorylation modification competition, cancers, neurodegenerative disorders, etc. However, there are still lots of unknown roles of it in gene regulation especially while there is existence of more than 1000 transcription factors and many other coactivators/repressors which might have influence in expression level with or without O-GlcNAc modification. In this project, we use CRISPR technology with catalytically inactive Cas9 from Streptococcus pyogenes fused with the only writer and eraser of O-GlcNAc to selectively target to the DNA sequence of interest by guide RNA to see what the result of additional modification or cleavage of O-GlcNAc on proximal proteins in gene regulation is. A cost and time efficient way for guide RNA construction is developed in the project with one-piece PCR and Gibson assembly for 2 different backbones of guide RNA: 11 guide RNA for each. Other different cloning methods have also been used for the future work. For the future work, second reporter will be introduced to normalize the luciferase signal. In addition, new metabolic O-GlcNAc reporter and Y289L GalT/ UDP-GalNAz could be used to find out proteins which might be modify by dCas9-OGT/OGA with click reaction. Furthermore, split OGA/Turbo ID system could also be used to reduce the background and find out proteins/modification sites which might be important to the gene regulation for DNA-protein or protein-protein interaction. / Thesis (MS) — Boston College, 2022. / Submitted to: Boston College.

Different techniques could be used for improving application performance in parallel systems. Studies have been shown that I/O communication delay is the main reason for different behavior of I/O intensive applications with specific requirements for performance optimization. So, using common strategies, generally defined and effective for computationally intensive applications may not have the same effect on performance improvement for these applications. Moreover, background system configuration effects on the behavior of the application and its performance. Growing use of parallel multi-core systems is an important factor in increasing performance and speeding up the applications. Since changing multi-core systems hardware is not an efficient method in satisfying different expectations of unique application, it is application developer's responsibility to design flexible and scalable code that is compatible with different environments. On the other hand, predicting application behavior and I/O requirements for I/O intensive applications with irregular communication patterns is a complicated and time-consuming task that pushes the problem to runtime impacts. Addressing this issue, we provided an overview on different techniques used for solving this problem. We have studied I/O bound parallel applications that use MPI as the communication method in order to define a general perspective to optimize cost performance ratio. Our designed experiments cover different setups for these applications in order to define various criteria that should be considered in design stage as well as runtime. Moreover, targeting one of the popular I/O intensive applications, we have discussed some possible solutions to speed it up on a multi-core system. / Master of Science

A pesquisa, caracterizada como um estudo de caso, de abordagem mista, adotou o m?todo quadripolar, o qual ? recomendado para investiga??es cient?ficas na ?rea das Ci?ncias Sociais Aplicadas. No tocante a revis?o bibliogr?fica, considerou-se conceitos como gest?o e media??o da informa??o e as v?rias vertentes da educa??o continuada, al?m de autores que estudaram a import?ncia do relacionamento com os egressos para as Institui??es de Ensino Superior. Almejando viabilizar uma proposta para o desenvolvimento de um canal de comunica??o entre os gestores do curso de Engenharia de Produ??o da UFRN e seus egressos, para o planejamento de a??es de educa??o continuada, a pesquisa utilizou duas t?cnicas de coleta de informa??es: o question?rio eletr?nico, para os egressos, e a entrevista, para os coordenadores da gradua??o e da p?s-gradua??o, al?m do chefe do departamento de Engenharia de Produ??o. O question?rio eletr?nico obteve 27,78% de retorno, sendo os dados tratados por meio de an?lise descritiva, com o aux?lio do editor de planilhas Microsoft Excel. Para a an?lise das entrevistas, utilizou-se o m?todo de an?lise de conte?do. Como resultados da pesquisa, observou-se de um modo geral, a potencialidade da constru??o de um canal para mediar a rela??o egressos-curso, tendo em vista que a maioria dos egressos se mostrou disposta a manter relacionamento com o curso, elegendo por meio das redes sociais a forma mais conveniente para a ocorr?ncia dessa rela??o. Al?m disso, uma parte expressiva dos egressos demandou a??es de educa??o continuada ap?s a conclus?o do curso, apontando a ?rea das engenharias como a mais buscada. Nas entrevistas, os gestores destacaram a import?ncia de se manter um relacionamento com os egressos, voltado para subsidiar decis?es no tocante as a??es do curso. Apesar disso, poucas s?o as a??es de comunica??o efetiva com os egressos e as existentes s?o operacionalizadas de forma prec?ria. Diante disso, entende-se que este estudo possa contribuir para que a institui??o desenvolva formas de contato mais efetivas com os seus egressos, n?o apenas no que diz respeito ? educa??o continuada, mas em outras a??es institucionais. / This research had as an objective to identify how the dialogue occurs between the undergraduate program in Management Engineering from UFRN and its alumni, for planning on continuing educational activities. The research, characterized as a case study, of varied approach, adopted a quadripolar method, in which is recommended for scientific investigations in the area of Applied Social Sciences. Regarding the literature review, it was considered concepts as management and measuring of information and many aspects of continued education, moreover the authors that studied the importance of the relationship with alumni and the Higher Education Institutions. Aiming to make feasible a proposal for the development of a communication channel between the managers of the program in Management Engineering from UFRN and its alumni, for planning on continuing educational activities, the research used two techniques for collecting information: an online survey for the graduates, and the interview, for the managers of the Management Engineering. The online survey obtained 27,78% return, being the data processed by means of descriptive analysis, with the aid of Microsoft Excel worksheets. For the analysis of the interviews, we used the method of content analysis. As search results, in general, the potential of building a canal to mediate the relationship between graduates, considering that most graduates proved willing to maintain relationship with the course, electing through social networks the most convenient for the occurrence of this relationship. In addition, a significant part of the graduates demanded actions of continued education upon completion of the course, pointing to the area of engineering as the most sought. In the interviews, the managers highlighted the importance of keeping a relationship with the alumni, providing sources on decisions regarding actions on the program. Despite this, there are few actions of effective communication with the alumni, and the existing ones are operated poorly. That being said, it is understood that this study can contribute so that the institution can develop more effective ways of contact with its alumni, not only regarding the continued education, but also in other institutional actions.

Esse destaque ? oriundo da percep??o da informa??o como recurso estrat?gico que resultou em mudan?as significativas no comportamento informacional dos colaboradores e nas estruturas das organiza??es. Outros fatores contribuem para o uso da GI nas universidades, sobretudo quando se observa o crescimento e expans?o das institui??es de ensino superior federais, principalmente em decorr?ncia da implanta??o do Plano de Reestrutura??o e Expans?o das Universidades Federais (REUNI), o que resultou em impactos significativos em suas demandas, principalmente no gerenciamento de atividades administrativas e da sobrecarga de informa??es. Tais demandas exigem que as universidades utilizem ferramentas que melhor gerenciem a busca, a sele??o, o tratamento, o armazenamento, o compartilhamento e o uso das informa??es, evidenciando pr?ticas da gest?o da informa??o com maior relev?ncia. A situa??o-problema identificada na Pr?-Reitoria de Gradua??o da Universidade Federal do Rio Grande do Norte (PROGRAD/UFRN) foi como otimizar a gest?o da informa??o do processo de cadastramento de ingressantes na unidade fazendo o uso da ferramenta eletr?nica dispon?vel? Este estudo justifica-se pela import?ncia que a PROGRAD/UFRN tem para a institui??o, em termos de n?mero de usu?rios de seus servi?os, volume de processos, atividades e documentos circulando em seu interior. Assim, objetiva-se, de modo geral, propor a otimiza??o da gest?o da informa??o de um processo estrat?gico da PROGRAD/UFRN. Especificamente objetiva-se: a) identificar pesquisas sobre modelos de GI aplicados em outras IES; b) caracterizar a gest?o da informa??o na PROGRAD/UFRN, com base na abordagem ecol?gica da informa??o; c) mapear um processo estrat?gico existente na PROGRAD/UFRN com o prop?sito de otimiz?-lo. Para alcan?ar tais objetivos desenvolveu-se um estudo de car?ter qualitativo, de natureza aplicada, descritiva, tendo como estrat?gia de pesquisa, a pesquisa-a??o. A pesquisa foi dividida em quatro etapas: diagn?stico da situa??o-problema, planejamento do estudo, interven??o e avalia??o. Para obten??o de dados foram realizadas pesquisa bibliogr?fica, an?lise documental, aplicados question?rios estruturados, realizadas entrevistas individuais semiestruturadas, organizados grupos focais e realizada observa??o participante. Os resultados obtidos indicam que a PROGRAD/UFRN vem empregando parcialmente os princ?pios da Ecologia da Informa??o em rela??o aos ambientes externo, organizacional e informacional, portanto a gest?o da informa??o ainda n?o ? integrada. Para otimizar a gest?o da informa??o na unidade se faz necess?rio que as pessoas, sejam melhor consideradas quanto ? produ??o, ao uso e ao compartilhamento das informa??es. A proposta de interven??o foi constru?da de forma colaborativa, implementada e avaliada, que subsidiou uma proposi??o mais consistente e ampla para a sua aplica??o. Entende-se que o aprimoramento do processo estrat?gico de cadastramento de discentes ingressantes na institui??o, fazendo uso da funcionalidade dispon?vel no sistema acad?mico ainda perpassa por alguns ?bices. Por fim, recomenda-se outros estudos que possam dar continuidade ?s pesquisas de ferramentas que possibilitem que a gest?o da informa??o em organiza??es p?blicas, como na UFRN, torne-se um recurso estrat?gico para o alcance pleno da sua miss?o e de seus objetivos. / Information management (IM) has a prominent role in all types of organizations, including the higher education institutions. This highlighted role is derived from the perception of information as a strategical resource that resulted in significant changes in the informational behavior of the associates and in the structures of the organizations. Other factors contribute to the use of IM in universities, mainly when it is observed the growth and expansion of federal higher education institutions, especially due to the employment of the Plan of Restructuring and Expansion of Federal Universities (REUNI), that resulted in significant impacts on their demands, mostly in the management of the administrative activities and the overload of information. Such demands require that universities use tools that better manage searching, selecting, processing, storing, sharing and using information, highlighting practices of information management with more relevance. The problem?s context identified in the Undergraduate Program?s Office of the Federal University of Rio Grande do Norte (PROGRAD/UFRN) was to optimize the information management in the process of registering the incoming students utilizing the available electronic tool? This study is justified for the importance that PROGRAD/UFRN has in the institution when it comes to the number of users of its services, volume of processes, activities and documents processing through. Thus, the objective is to propose the optimization in the information management of a strategical process of PROGRAD/UFRN. The specific objectives are: a) identify research on models of IM applied to other HEI; b) characterizing the information management of PROGRAD/UFRN, with basis on the information ecological approach; c) mapping an existing strategical process in PROGRAD/UFRN with the purpose to optimize it. To fulfill such objectives a qualitative, descriptive and applied study was developed, having the research-action as a strategy. The study was divided in four phases: diagnosing the problem?s context, planning the study, intervention and evaluation. To acquire the data, it was conducted a literature review, documental analysis, structured surveys applied, semi-structured interviews, focal groups organized and performed the participant observation. The results obtained indicate that PROGRA/UFRN has been employing partially the principals of Information Ecology regarding the external environments, organizational and informational, thus the information management is not integrated yet. To optimize the information management in this institution it is necessary that the people are taken into account when it comes to productivity, the use and sharing of information. The intervention proposal was built in a collaborative, implemented and evaluated manner that subsidized a more consistent and broad proposition for its use. It is understood that the enhancement of the strategical process of registering incoming students in the institution, utilizing the available functionality in the academic system still faces some obstacles. Finally, it is recommended that other studies are continued for the research of tools that make it possible the information management in public organizations, such as UFRN, become a strategical resource to reach its complete mission and objectives.

A conectividade e a mobilidade de alunos e professores est?o associadas ? utiliza??o dos mecanismos sociais e t?cnico-educativos na CVA, definidos nesta investiga??o como dispositivos de enuncia??o, did?tico, de comunica??o e de conectividade, os quais s?o estruturados a partir do desenho pedag?gico e acionados pelas socializa??es, e que viabilizam as a??es dos sujeitos, pois se constituem como as vias de acesso para as informa??es e os servi?os educacionais disponibilizados virtualmente, configurando as rela??es sociais de uma CVA e um comportamento on-line pautado na tele-a??o e na tele-educa??o. As mobilidades dos alunos pelos dispositivos podem ser representadas por meio de vetores que s?o simulacros dos processos socioeducativos instaurados na CVA, pois representam o agrupamento dos dispositivos acionados pelos agentes para prover as a??es referentes ?s avalia??es, ao suporte t?cnico e pedag?gico, aos materiais did?ticos, ?s informa??es, ?s intera??es, e o entrecruzamento destas a??es est? associado aos processos intelectuais, cognitivos e sociais decorrentes da educa??o on-line. Na educa??o on-line os alunos vivenciam um contexto cibercultural em que preponderam as rela??es sociais e comunicativas mediatizadas pelo universo institucional, por?m quando estes alunos se matriculam na Universidade Virtual passam a compor um agrupamento de pessoas que se relacionam a partir de uma rede de contatos previamente disponibilizada pela institui??o, ou seja, a CVA como l?cus em que se efetivam rela??es de sociabilidade tamb?m se constitui como l?cus potencializador de socialidade, uma vez que as pessoas que dela participam, durante seu percurso universit?rio, constituem novos subgrupos para socializa??es em espa?os virtuais paralelos, de acordo com as afinidades, com os interesses e com as identifica??es em projetos que tem como vi?s central viver outra experi?ncia que n?o a educativa, superando neste ponto a rela??o formal e institucional.
