A gestão da comunicação em ambientes distribuídos para o desenvolvimento de software (DDS) é um tema que tem sido investigado a fim de garantir a consistência dos cenários de colaboração. Como este assunto é relativamente recente, e envolve questões técnicas e humanas, é comum que novos conceito e características do processo de comunicação em DDS sejam levantadas. Neste sentido, este trabalho objetivou criar um protocolo a fim de estruturar a comunicação em ambientes DDS. A validação das hipóteses que o subsidiaram se deu por meio de experimentação, que foi realizada por meio de atividades realizadas por alunos do curso de pós-graduação em informática (PPGI) da Universidade Tecnológica Federal do Paraná- Campus Cornélio Procópio. Para experimento configurou-se o ambiente de modo que este tivesse as características de um ambiente distribuído. Propôs-se uma atividade que consistia em um conjunto de subatividades, que deveriam ser realizadas por cada grupo de alunos, que estavam fisicamente separados, que os obrigou a utilizarem ferramentas de comunicação síncronas e assíncronas. Ao final do experimento, atingiu-se as expectativas, pois conseguiu-se estruturar a comunicação em camadas hierárquicas, que configurou e definiu o protocolo de comunicação em projetos de DDS. / The communication management in environments for distributed software development (DSD) has been investigated to ensure the consistency of collaboration scenarios. As a recent topic that involves technical and human issues, new concepts and processes of communication in DSD have been raised. Thus, this study presents a protocol to structure communication in DSD environments. The protocol was defined using the validation of hypotheses in an experiment, which was conducted by means of activities performed by master students in computer science. In the experiment, we set up the environment that had the characteristics of a distributed environment. It was proposed an project consisting of a set of activities to be carried out by groups of students. Each group was physically separated, forcing them to use synchronous and asynchronous communication tools. At the end, the expectations were met since we were able to structure the communication in hierarchical layers, setting up and defining the communication protocol in DSD projects.

Essas ferramentas possibilitam o crescente desenvolvimento de comunidades online, assim como de aplicativos para o desenvolvimento de tais comunidades. Nesse contexto, desenvolvem-se ambientes virtuais de ensino-aprendizagem e trabalho colaborativo online com ferramentas que podem potencializar projetos de formação continuada de professores, seja no aspecto da formação ou na gestão dos trabalhos. Com essa perspectiva, utilizaram-se ferramentas computacionais online durante o projeto Ribeirão Anhumas na Escola, realizado em parceria entre Institutos de ensino, pesquisa e escolas públicas no município de Campinas-SP, com apoio da Fapesp e Petrobras, iniciado em fevereiro de 2007. Esse projeto teve como eixo integrador os problemas ambientais de Campinas-SP e a construção de conhecimentos escolares. Dentre as TCIs, destacou-se o uso do ambiente virtual TelEduc, por meio do qual ocorreram trocas de mensagens via correio, discussões em fórum, além da documentação de todo o projeto, organizada por meio das ferramentas do ambiente: atividades, materiais de apoio e portfólios individuais e de grupo. Nesse trabalho buscou-se cartografar os caminhos de uso dessas TICs, visando compreender como potencializaram a construção de conhecimentos escolares e o trabalho colaborativo, apresentando uma visão geral do uso do ambiente virtual. Fez-se a análise detalhadas do uso das TICs a partir de um recorte de uma das atividades construídas por um dos grupos de professores. Para análise da atividade escolhida, optou-se pela ação mediada como eixo norteador e desenvolveu-se uma proposta de organização das mensagens do fórum, com conexões para outras interações mediadas (correio e encontros presenciais), objetivando o desenvolvimento de uma representação gráfica que possibilita a análise integrada da ação mediada, com foco na visão micro e buscando algumas relações com a macro. A partir das observações e análises das atividades desenvolvidas, apresentam-se algumas reflexões e possibilidades de outras formas de utilização das TICs que potencializem o uso das ferramentas computacionais em projetos, como o apresentado nesse trabalho. Sobre o uso do TelEduc, o trabalho indicou contribuições significativas para a construção dos saberes escolares, assim como indícios das TICs mediando a ação dos grupos e potencializando o trabalho colaborativo / Abstract: Advances in information and communication technology (ICT) continually bring new possibilities for online social interaction, including a wide variety of tools to mediate communication (websites, blogs, wikis, webconferencing). These tools enable the increasing growth of online communities, as well as applications for the communities development. In this context, it develops virtual environments for online teaching and learning, and collaborative work, which are tools that, among other possibilities, can leverage continued education programs for teachers, whether in the formation or management of the work. With this perspective, online computational tools were used for the project "Ribeirão Anhumas in the School". This project held in partnership along with educational institutes, research institute and public schools from Campinas-SP , with financial support of FAPESP and Petrobras (since February 2007). This project works the environmental problems from the city of Campinas-SP as integrator axis and the construction of school knowledge. Among the ICT, show up the use of virtual environment TelEduc, through which there were messages by mail, discussion forum, besides the documentation of the entire project, organized by the tools of TelEduc: activities; support materials; individual and group portfolios. In this study a mapping was made the way of ICT use, to comprehend how to leverage the construction of school knowledge and collaborative works, presenting an overview of the virtual environment use. For detailed analysis of the use of ICT, a cut in the activities was made by a group of teachers. To analyze the chosen activity, was adopted the mediated action as a guiding and an organization purpose for forum's messages was developed, with connections to others mediated interactions (mailing and face meetings), focusing on the micro view and seeking some relations with the macro. The objective of this purpose is to develop a graph which allows the integrated analysis of mediated action. By this observations and analyzes of the activities, some reflections and other possibilities to use ICT is shown, that allows to increase the computational tools in project, like in this study. About the TelEduc use, the study indicated significant contributions to the construction of school knowledge, as well as ICT to develop action of groups and collaborative work / Doutorado / Doutor em Ciências

This research aimed to analyze, through the technique of free recall, the social representations of teachers and students of IF Sudeste MG ? C?mpus Rio Pomba on Information and Communication Technologies in education. The research was conducted with a population of sixty (60) teachers and 200 (two hundred) students of the C?mpus Rio Pomba. The theoretical basis of this research refers to the Theory of Representations, Serge Moscovici. The survey data were analyzed using the technique of frame construction of four houses and the responses were analyzed with the aid of a computer program called EVOC 2003 ?, which combines the frequency of recall of each word to their order of invocation, seeking establish the degree of projection of the elements represented in each group. The results showed that social representations of Information and Communication Technologies in education influence the behavior of both teachers and students of the educational scene inserted in the information society. The data revealed that between teachers' pedagogical practice and the awareness that they have the attitude they should take in knowledge construction mediated by technology there is a great gulf, which is supported by social representations related to the fear of being overcome at the cognitive level of lose the monopoly of knowledge and sharing with the students construction of knowledge. With regard to social representations of students, the results showed that they share high expectations for teachers and school. The element of knowledge is presented as the core of social representations both for teachers and for students. In addition to the social representations of teachers and students of the IF Sudeste MG ? C?mpus Rio Pomba about the Information Technologies and Communication in education, this study sought to reflect on the Information and Communication Technologies in education and rescue some of the social construction of society riopombense on the creation of the Escola Agr?cola de Rio Pomba, today IF Sudeste MG ?

Os dados da pesquisa foram analisados por meio da t?cnica de constru??o do quadro de quatro casas e as respostas foram analisadas com o aux?lio do programa de computador denominado EVOC 2003?, que combina a frequ?ncia de evoca??o de cada palavra com sua ordem de evoca??o, buscando estabelecer o grau de sali?ncia dos elementos da representa??o em cada grupo. Os resultados mostraram que as representa??es sociais das Tecnologias da Informa??o e Comunica??o na educa??o influenciam o comportamento tanto dos docentes quanto dos discentes no cen?rio educacional inserido na sociedade da informa??o. Os dados revelaram que entre a pr?tica pedag?gica dos docentes e a consci?ncia que os mesmos possuem da postura que devem assumir na constru??o do conhecimento mediada pelas tecnologias existe um grande abismo, que ? sustentado pelas representa??es sociais ligadas ao medo de serem superados no plano cognitivo, de perderem o monop?lio do saber e de dividirem com os discentes a constru??o do conhecimento. No que diz respeito ?s representa??es sociais dos discentes, os resultados demonstraram que os mesmos partilham expectativas positivas em rela??o aos professores e ? escola.

Le « knotworking » représente une forme innovante d’organisation du travail dans laquelle la collaboration prend place sous la forme d’épisodes en fonction des besoins de la situation. Cela implique de multiples défis pour soutenir la collaboration, dus à la nature épisodique, improvisée et inter-organisationnelle de cette collaboration. Notre objectif dans cette thèse est de relever ces défis, au travers d’un cas d’étude sur les pratiques collaboratives d’un groupe de professionnels de santé libéraux prenant en charge des patients à domicile. Nos résultats montrent : 1) La centralité des artefacts de coordination ; 2) comment la focalisation sur la qualité de vie des patients amène les acteurs de la prise en charge à traiter de problèmes au-delà du périmètre médical ; 3) que les acteurs de santé passent par différents rythmes de collaboration en fonction de l’évolution de la situation de leur patient. Ces résultats nous ont permis de définir des principes de conception et de développer l’application CARE (Classeur pour une Approche en Réseau Efficace), accessible sur une tablette et restant au domicile du patient. Les retours montrent le rôle potentiel des technologies pour motiver la participation de nouveaux acteurs de santé, et pour la mise en place d’un espace partagé pour les différents participants de la prise en charge. Notre travail contribue à la recherche en TCAO en mettant l’accent sur un nouveau modèle d’organisation du travail (knotworking) et en proposant la première étude de cas de conception d’un outil pour assister la collaboration dans ce contexte / The development of new modes of working raises new challenges for supporting collaboration. Knotworking represents an innovative way of organizing work where collaboration occurs in episodes depending on the requirement of the current situation. Supporting collaboration in knotworking presents multiple challenges due to the episodic, improvised, and cross-boundary nature of the collaboration. Our objective in this thesis is to tackle these challenges. Thus, we conducted a design case study investigating the collaborative practices of a group of self-employed care professionals organized as an association which take care of patients at home. The results show: 1) the centrality of the coordinative artifacts for sharing information and coordinating the work; 2) how focusing on patients’ quality of life leads care actors to address issues beyond the medical scope; 3) how the care actors experience different rhythms of collaboration depending on the patient’s situation. Based on these results, we defined some implications for design and developed the CARE application (Classeur pour une Approche en Réseau Efficace), which is accessible via a tablet and stays at the home of the patient. Feedback reveals the potential role of technologies in motivating the participation of new care actors, and in the creation of a shared place for diverse participants. Our work contributes to CSCW by bringing to focus a new model of organizing work named knotworking and by providing a first design case study aiming at supporting collaboration in this context

Nesta dissertação, nós propusemos um método para atribuição de autoria que é de cem a mil vezes mais rápido que o estado da arte. Nós também obtivemos uma acurácia 65\% na classificação de 50 autores. O método proposto se baseia numa representação de caracteristicas escalável utilizando os padrões das mensagens dos micro-blogs, e também nos utilizamos de um classificador de padrões customizado para lidar com grandes quantidades de dados e alta dimensionalidade. Por fim, nós discutimos a redução do espaço de busca na análise de centenas de suspeitos online e milões de micro mensagens online, o que torna essa abordagem valiosa para forense digital e aplicação das leis / Abstract: With the ever-growing use of social media, authorship attribution plays an important role in avoiding cybercrime, and helping the analysis of online trails left behind by cyber pranks, stalkers, bullies, identity thieves and alike. In this dissertation, we propose a method for authorship attribution in micro blogs with efficiency one hundred to a thousand times faster than state-of-the-art counterparts. We also achieved a accuracy of 65% when classifying texts from 50 authors. The method relies on a powerful and scalable feature representation approach taking advantage of user patterns on micro-blog messages, and also on a custom-tailored pattern classifier adapted to deal with big data and high-dimensional data. Finally, we discuss search space reduction when analysing hundreds of online suspects and millions of online micro messages, which makes this approach invaluable for digital forensics and law enforcement / Mestrado / Ciência da Computação / Mestre em Ciência da Computação

Email communication within a diverse workplace poses intercultural communication challenges (Martin & Nakayama, 2007). This study aims to make a contribution to the literature by examining how these challenges can be addressed through email computer training. For this study, I set out to understand and demonstrate how, within the instructional design process, contextualized curriculum can be created that integrates intercultural competency and email proficiency. This thesis includes a draft of an instructional plan and course outline for an email computer class that focuses on developing intercultural awareness and skills in the context of an email training course. First, I examined email computer curricula, specifically the topics, course goals, and course objectives common to the curricula. As a result of this examination, I discovered that email training is limited to the technical aspects of email communication. Additionally, I surveyed intercultural communication professionals about intercultural topics applicable to email communication. Their survey responses indicated cultural differences account for some, but not all email workplace challenges. For example, they believed it is important to address intercultural elements like low vs. high context when writing an email message, and power distance and levels of formality when writing greetings and closings. Additionally, their feedback indicated that it is important to address direct vs. indirect communication styles when writing the main point and linear vs. circular cognitive styles when organizing text within an email. I incorporated their perspectives in my course outline. Finally, experts from the fields of instructional design, intercultural communication, and computer training reviewed a draft of the plan and outline. Although their feedback indicated that the premise and approach were sound and achievable, they differed in their evaluation of specific elements of the course. In general, their perspectives reflected their professional focus. For example, they either recommended a stronger focus on the technical aspects or a stronger focus on the intercultural aspects of the course design. Detailed comments pertained to the fine-tuning of the objectives, timing of the individual lessons, and other instructional elements needed for any polished professional course outline
