Board and Card Game (BCG) sites allow people to connect over the Internet to play virtual versions of games, like Chess or Canasta, that can be played on a physical table. Many of these sites are successful as they have large memberships, are extremely active, and persist for a long time. However, when analysing the BCG site PlayOK, I found that the community did not exhibit behaviours traditionally associated with successful community: there was little verbal communication; most interactions were impersonal and once-only; and the player population was highly transient. The problem is that designers and researchers have a poor understanding of the characteristics of BCG communities, and how those characteristics are affected by factors that are typically seen as important for community such as size and leadership. In this thesis, I improve understanding of BCG site communities through three studies: 1 No research describes community behaviour in BCG sites. I analysed community behaviour in the PlayOK BCG using ‘social accounting’ methods, which generate summary behavioural statistics from log traces. I found that players were motivated by wanting an opponent, without being concerned with the opponent’s identity. 2 The effects of community size on BCG community behaviour are poorly understood. I used social accounting analyses to compare a small site (GameCenter), with the large PlayOK site. I found that the smaller GameCenter exhibits very similar behaviour but is less efficient due to the smaller population. 3 There are no empirical studies of the role of leadership in online game communities through a substantial change in leadership. I used social accounting techniques to analyse GameCenter BCG before and after a substantial change in leadership. I found that sub-communities responded differently according to how they relied on the leadership for their core activities. This research is the first to identify a type of community that is sustained through impersonal, non-verbal interactions. This important because examples exist in BCG sites and may exist as sub-communities in other settings such as online discussion forums, social media sites, and other online games.

A pesquisa que deu origem à essa dissertação de mestrado está pautada na análise acerca da concepção de trabalho cooperativo para o Movimento dos Trabalhadores Rurais Sem Terra (MST) e, na conseqüente implementação de uma Cooperativa de Produção Agropecuária – CPA, no Assentamento Trinta de Maio em Charqueadas, no RS, considerada como um projeto alternativo de desenvolvimento econômico, social e cultural para as famílias assentadas, visando contrapor a lógica do modelo capitalista de produção. Através da metodologia da pesquisa-participante, este estudo procura refletir e desvelar os aspectos e desdobramentos que conduziram para a gradativa divisão entre algumas famílias assentadas e sua conseqüente saída da cooperativa, partindo para o modelo de produção familiar e associativo. Analisa também, outras formas de concepção de trabalho cooperativo forjadas entre as famílias que por diversas motivações, optaram por se desligar da cooperativa do assentamento. Apresenta também, a relação dialógica entre as categorias educação e trabalho cooperativo e as conseqüentes contradições que emergem no seio das relações sociais consolidadas entre as famílias que constituem a cooperativa, tendo como eixo condutor da pesquisa, a educação e o trabalho cooperativo, alicerçadas nos referencias teóricos de Freire e Marx. / The research that gave rise to this dissertation is based on the analysis concerning the comprehension of cooperative work for the Landless Workers' Movement (MST), and the consequent implementation of an Agricultural Production Cooperative – APC, in the Trinta de Maio Settlement, considered an alternative to economic, social and cultural development of the settled families, contradicting the logic of the capitalist mode of production. Through the research participant methodology, this study aims at reflecting about the factors and consequences that led up to the gradual division from some settled families and the consequent choice for household production model. This study also examines different conceptions of cooperative work that exist between the settled families. Besides, it presents the dialogic relationship between education and cooperative work and the resulting contradictions within these families, having the education and cooperative work as essential purpose of this search.

As an alternative organization form to the unemployment crisis, cooperatives assist not only popular basis layers, but also to an expressive contingent of qualified workers with a good living standard. The case study was carried out in a popular cooperative "Friends of the Garbage ", located in Guaratinguetá city - SP. The methodology used will be the unique case study, like data collection techniques and direct observation, analysis of documents of the cooperative and interviews with cooperated people and manager. The general objective was to analyze if the Cooperative of Work mentioned acts as work generating and income. The main concepts of Solidary Economy and work cooperative were defined. The subject was analyzed through the investigation of the perceptions of cooperated people s life conditions before and after the entrance in the respective cooperatives. / O movimento de cooperativas populares vem crescendo exponencialmente nós últimos anos. Como forma de organização alternativa à crise do desemprego, as cooperativas atendem não só às camadas de base popular, mas também a um contingente expressivo de trabalhadores qualificados e com um bom padrão de vida. O estudo de caso foi realizado em numa cooperativa popular Amigos do Lixo , localizada na cidade de Guaratinguetá SP. A metodologia utilizada foi o estudo de caso único, como técnicas de coleta de dados, observação direta, análise de documentos e entrevistas com cooperados e gestor. O objetivo geral foi analisar se a Cooperativa de Trabalho citada atua como geradora de trabalho e renda. Procurou-se descrever os principais conceitos que definem a Economia Solidária e a Cooperativa de trabalho. A questão foi analisada por meio da investigação das percepções das condições de vida dos cooperados antes e após o ingresso nas respectivas cooperativas.

Research in Computer-Supported Cooperative Work (CSCW) has identified a gap - the, so called, social-technical gap - between the wide range of human social interactions that CSCW ideally should support and what current technology actually does support. At the same time recent work in cognitive science and CSCW has begun to elucidate the multifarious roles that the body plays in cognitive processes as well as many forms of social interaction, e.g. gestures, pointing, eye-contact and bodily mimicry. The aim of this dissertation has been to analyse to what degree different aspects of embodied social interaction are supported by different types of synchronous, remote location CSCW technology, and to develop recommendations for future development concerning aspects of embodiment. For this purpose, a number of crucial aspects of embodied social interaction have been identified and about twenty CSCW systems - both research prototypes and commercial systems - have been analysed with respects to how well they support these different aspects. The analysis shows that most CSCW systems only support a very limited range of aspects of embodied social interaction.

Inom Linköpings kommun finns en decentraliserad organisation för publicering av material på Linköpings kommuns webbplats www.linkoping.se. Inom den ledande gruppen i organisationen har man insett att en wiki skulle kunna underlätta arbetet för medlemmarna i organisationen att dela kunskap med varandra. Studien syftar till att identifiera och verifiera faktorer som ger en framgångsrik wiki. Dessa kan sedan användas som bakgrund vid skapandet av en eventuell wiki för organisationen eller andra organisationer inom Linköpings kommun. Studien består av en litteraturstudie och en fallstudie av fallstudie av LKDATAs (affärsområdet för IT och kommunikation inom Linköpings kommun) dagligen använda och väl fungerande wiki. Litteraturstudien resulterade i sex utvalda framgångsfaktorer: Social kultur, Ledningens inflytande, Renommé, Nytta, Reciprocitet samt Användarvänlighet. Fallstudien genomfördes med hjälp av en enkätundersökning på LKDATA angående de fyra olika delarna inom användning: spenderad tid, frekvens av användning, frekvens av sökning samt frekvens av delning av information på wikin. Av svaren från enkäten gjordes en korrelationsanalys samt en regressionsanalys i SPSS. Analysen visade på svaga men signifikanta korrelationer mellan hur mycket wikin används och framförallt Nytta. Däremot kan inga slutsatser dras ur regressionsanalysen. Den viktigaste faktorn som påverkar användandet på LKDATA verkar dock vara vilken grupp den anställde tillhör och alltså vilka arbetsuppgifter denne har snarare än andra faktorer.

Notre travail de recherche porte sur l’analyse de l’action du professeur et ses interactions avec les élèves dans le domaine spécifique de l’étude du numérique en Cours Préparatoires. L’objectif de notre thèse est d’analyser l’action du professeur et ses pratiques didactiques en classes, et formatives dans une Cellule d’Animation Pédagogique. La première partie comporte une présentation du contexte socio économique et éducatif du Niger. Nous nous interrogeons ensuite sur les pratiques professorales permettant ou non aux élèves de prendre de réelles responsabilités par rapport aux savoirs, et sur la pertinence du travail de conception collective de séances. Dans la deuxième partie, nous exposons nos outils théoriques, les travaux antérieurs en lien avec nos objets de recherche, et la problématique générale de notre travail. La troisième partie est consacrée à la démarche méthodologique qui fonde notre étude sur l’analyse des manuels, des vidéos de classe et les observations in situ. La quatrième partie examine les ressources mathématiques utilisées à l’écoleprimaire au Niger, en interrogeant l’influence de ces ressources sur les pratiques habituelles des professeurs enquêtés. Les cinquième et sixième parties analysent les séances empiriques en termes de topogénèse, et de recours aux systèmes sémiotiques pour étudier le savoir en jeu dans les situations didactiques. Dans la septième partie, nous proposons un dispositif innovant de formation continue sur la conception collective de leçons dans une CAPED. En conclusion, dans une huitième partie nous présentons d’abord une synthèse de nos résultats, et nous exposons ensuite les perspectives que ce travail de recherche offre en termes de propositions en vue de l'élaboration d'ingénieries didactiques qui pourraient permettre la mise en place d’un travail coopératif entre professeurs et chercheurs / Our research focuses on the teacher's action and his interactions with students in the specific field of the study of digital in grade 2. The objective of this PhD dissertation is to analyze the teacher's action and his didactic practices in classes, and training practices in a CAPED in the Niger context. The first part of this PhD dissertation includes a presentation of the socio-economic and educational contexts in Niger. Then we examine the teaching practices in order to see if they allow students to take or not real responsibilities in relation to knowledge, and the appropriateness of collective design work sessions.In the second part, we present our theoretical tools, previous work related to our research objects, and the general problem tackled by our work. The third part is devoted to our methodological approach based on the study of textbook analyze, videos of classes and field observations. The fourth section discusses the mathematic resources used in the primary education in Niger and question the impact of these resources on the observed teachers' usual practices. The fifth and sixth sessions analyze empirical lessons in terms of topogenesis, and semiotic systems to study the knowledge involved in the didactic situations. In the seventh part, we propose an innovative in-service training based on the design of lessons in a collective CAPED. In conclusion, in an eighth part we first present a summary of our results, and then we present the perspectives that this research offers in terms of further developments of didactic engineering that could allow the implementation of a collaborative work between teachers and researchers
