The work establishes a broad dialogue with several authors who reflect on the history of scientific publication, the evolution of magazines printed for the electronic media, especially the digital ones, the current principles of science for dissemination, the virtual reading, open access, and the curricular narrative. The instruments for collecting data were the researcher's field diary, the list of discussion created for the group of instructors from e-Curriculum magazine, recorded chats, recorded videos, testimonial e-mail of the subjects, letters of indexing organizations and a CD-ROM of the historical archives of e-Curriculum magazine. The research on the participatory action model provided the necessary engagement to hear the speeches of subjects who lived intensely the universe of the creation of a journal, enabling to confirm that, from the subject-authors perspective, the technological media are spaces of preparation and creation of new locations for the spread and dissemination of research, as spaces for learning socialization. The thesis shows that the electronic journals, in any area of knowledge, need to be explained through research for their existence. The investigation indicates that it is possible to create a journal in postgraduate programs and concludes that it is necessary to open up intense dialogues in these programs for the development of science in the country. It is not enough to produce magazines without their correspondent political-pedagogical effort for their use and effectiveness in the research domain. Finally, it was concluded that it is possible to construct a curricular narrative from the journey, from the search for the construction of pedagogical and social utopias, without losing or failing to develop the prescriptive curriculum / Este estudo situa-se na linha de pesquisa Novas Tecnologias e Educação, procura descrever e anal isar o processo de const rução de uma revista cientí fica elet rônica em Educação e Currículo, por um grupo de alunos do Doutorado do Programa de Pós-graduação Educação: Currículo de 2004 da PUC-SP. O trabalho estabelece amplo diálogo com diversos autores que refletem sobre a história da publicação cientí fica, a evolução das revistas impressas para os meios eletrônicos, especialmente os digitais, os princípios regentes de ciência para disseminação, sobre a leitura vi rtual , o acesso aberto, ou como se conhece, do open access, e da narrativa curricular.

A pesquisa em modelo de ação participava propiciou o engajamento necessário para ouvir os discursos de sujeitos que viveram intensamente o universo da construção de um periódico cientí fico, sendo possível confirmar que, pela perspectiva destes sujeitos-autores, os suportes tecnológicos se constituem em espaços de elaboração e de criação de novos locais para a disseminação e divulgação de pesquisas, como espaços de social ização das aprendizagens. A tese aponta que os periódicos eletrônicos, em qualquer área do conhecimento, necessitam serem significados por meio de pesquisa para sua existência. A investigação aponta que é possível const rui r um periódico em programas de pós-graduação e conclui que é necessário abri r-se diálogos intensos nestes programas para o desenvolvimento da ciência no país. Não é suficiente lançar revistas sem o correspondente t rabalho político-pedagógico para seu uso e eficácia no domínio da pesquisa. Por fim, foi concluído que é possível construi r uma narrativa curricular a parti r do t rajeto, da busca para a construção de utopias pedagógicas e sociais, sem perder ou deixar de se desenvolver o currículo prescritivo

Trata-se do processo de disseminação ou difusão de políticas públicas de cultura, a partir da análise de implantação do Programa de Valorização de Iniciativas Culturais, VAI-SBC, programa de fomento à produção cultural da prefeitura de São Bernardo do Campo, em relação com o programa homônimo e sua matriz conceitual, o Programa VAI, desenvolvido na cidade de São Paulo. Embora ambos se filiem ao mesmo campo político-ideológico, ao ser adaptado à localidade do Grande ABC, variáveis internas e externas ao programa, tais como a experiência acumulada pelos fazedores de política (policy makers), os constrangimentos impostos pela situação político-administrativa do município e as características de desenvolvimento especificas do campo cultural local influenciaram o modo como ocorreu a escolha do modelo de formulação, agindo decisivamente na construção do seu objeto e de suas diretrizes. O estudo foi realizado a partir de pesquisa de documentos, leis, imprensa comercial e oficial, programas, entrevistas, depoimentos, projetos e ações, considerando aspectos políticos, culturais, artísticos e sociais na realização da política pública de cultura / It is about the process of dissemination or diffusion of culture public policies, from the analysis of the Cultural Initiatives Valuation Program, VAI-SBC, development program to cultural production of the São Bernardo do Campos city hall, in relation to the homonym program and its conceptual basis, the VAI Program, developed on the city of São Paulo. Although both join the same political-ideological field, when being adapted to the location of Grande ABC, internal and external variables to the program, such as the accumulated experience by the policy makers, the embarrassments imposed by the political-management situation of the city hall and the development characteristics of the local cultural field, influenced the way how the choice of the formulation model occurred, acting decisively on the construction of its object and its guidelines. The study was based on research on documents, laws, commercial and official press, programs, interviews, testimonies, projects and actions, considering politcal, cultural, artistic and social aspects in the accomplishment of the public policy of culture

La dissémination d’information dans les réseaux VANET est une opération fondamentale pour la sécurité routière. Il est dès lors nécessaire de concevoir et mettre en oeuvre des algorithmes efficaces et adaptatifs pour la dissémination d’informations sélectives et pertinentes.Dans ce travail, des approches Bio-inspirées sont proposées, à partir des comportements auto-organisés des essaims comme les colonies de fourmis et d’abeilles. Ces approches visent à fournir à chaque véhicule des informations en provenance de son environnement et alerter les conducteurs. Dans la première approche, le système de communication direct et indirect des fourmis est utilisé. Les fourmis partagent les informations sur les sources de nourriture avec des membres de la colonie en sécrétant la phéromone sur leurs chemins. La deuxième approche est inspirée par le système de communication des abeilles. Les abeilles partagent les informations à propos des sources de nourriture avec les autres membres de la ruche par des messages spécifiques, selon l’importance de ces sources.Une nouvelle mesure de "pertinence" associée aux messages est définie, par analogie à la sécrétion des phéromones des fourmis et au niveau de l’intensité des messages pour les abeilles, pour disséminer des informations de sécurité dans une zone géographique. Les simulations sont effectuées en utilisant le simulateur NS2 pour mesurer l’efficacité des approches proposées sous différentes conditions, en particulier en termes de densités et vitesses des véhicules. / Information dissemination in Vehicular Ad hoc Networks (VANETs) is a fundamental operation to increase the safety awareness among vehicles on roads. Thus, the design and implementation of efficient and scalable algorithms for relevant information dissemination constitutes a major issue that should be tackled.In this work, bio-inspired information dissemination approaches are proposed, that use self-organization principles of swarms such as Ant and Honey Bee colonies. These approaches are targeted to provide each vehicle with the required information about its surrounding and assist drivers to be aware of undesirable road conditions. In the first approach, Ant’s direct and indirect communication systems are used. Ants share information about food findings with colony members by throwing pheromone on the returning to the nest. The second, an RSU-based approach is inspired by the Bee communication system. Bees share profitable food sources with hive-mates in their hive by specific messages.A “relevance” value associated to the emergency messages is defined as an analogue to pheromone throwing in Ant colony, and as an analogue to profitability level in Bee colony, to disseminate safety information within a geographical area. Simulations are conducted using NS2 network simulator and relevant metrics are evaluated under different node speeds and network densities to show the effectiveness of the proposed approaches.

Advances in computing and wireless communication technologies have increased interest in smart vehicles, vehicles equipped with significant computing, communication and sensing capabilities to provide services to travelers. Smart vehicles can be exploited to improve driving safety and comfort as well as optimize surface transportation systems. Wireless communications among vehicles and between vehicles and roadside infrastructures represent an important class of vehicle communications. One can envision creating an integrated radio network leveraging various wireless technologies that work together in a seamless fashion. Based on cost-performance tradeoffs, different network configurations may be appropriate for different environments. An understanding of the properties of different vehicular network architectures is absolutely necessary before services can be successfully deployed. Based on this understanding, efficient data services (e.g., data dissemination services) can be designed to accommodate application requirements. This thesis examines several research topics concerning both the evaluation and design of vehicular networks. We explore the properties of vehicle-to-vehicle (v2v) communications. We study the spatial propagation of information along the road using v2v communications. Our analysis identifies the vehicle traffic characteristics that significantly affect information propagation. We also evaluate the feasibility of propagating information along a highway. Several design alternatives exist to build infrastructure-based vehicular networks. Their characteristics have been evaluated in a realistic vehicular environment. Based on these evaluations, we have developed some insights into the design of future broadband vehicular networks capable of adapting to varying vehicle traffic conditions. Based on the above analysis, opportunistic forwarding that exploit vehicle mobility to overcome vehicular network partitioning appears to be a viable approach for data dissemination using v2v communications for applications that can tolerate some data loss and delay. We introduce a methodology to design enhanced opportunistic forwarding algorithms. Practical algorithms derived from this methodology have exhibited different performance/overhead tradeoffs. An in-depth understanding of wireless communication performance in a vehicular environment is necessary to provide the groundwork for realizing reliable mobile communication services. We have conducted an extensive set of field experiments to uncover the performance of short-range communications between vehicles and between vehicles and roadside stations in a specific highway scenario.
