Les communautés de savoirs en tant qu'espaces hybrides, mettent en jeu, d'une part, des individus qui interagissent au sein d'un réseau social et qui produisent des contenus localement, et d'autre part, des entités sémantiques, liées au sein d'un réseau sémantique doté d'une structure autonome. Cette thèse vise à explorer les dynamiques sociales et sémantiques qui animent ces communautés de savoirs, ainsi que leur couplage structurel. Elle s'appuie essentiellement sur deux types d'objets empiriques : les communautés scientifiques et les blogosphères politiques, dont nous suivons l'activité grâce à l'observation in-vivo de leurs traces digitales. Notre ambition est de réaliser une reconstruction phénoménologique réaliste des dynamiques sociosémantiques de ces communautés de savoirs. Pour ce faire, nous distinguons entre les dynamiques liées à la morphogenèse puis à la phylogenèse des réseaux qui composent ces systèmes et les processus dynamiques de diffusion qu'ils supportent. Les méthodes de caractérisation de la morphogenèse des communautés de savoirs permettent, d'une part, de repérer et représenter les structures et propriétés émergentes de ces communautés de savoirs, et d'autre part, de mettre en évidence les comportements individuels réguliers qui les animent. La phylogenèse des communautés de savoirs consiste en la reconstruction des dynamiques de ces structures de haut-niveau émergeant au cours de la morphogenèse. L'analyse des processus de diffusion nous amène à interroger les déterminants structurels micro et macro qui conditionnent la circulation d'information dans ces communautés. L'ensemble de ces approches nous permettent de décrire les communautés de savoirs comme des systèmes dont les dimensions sociale et sémantique sont, par essence, en co-évolution.

Political blogs have emerged as a new journalistic format that has gained influence on the political discourse in the United States. Previous research has shown that this influence stems mainly from attention given to blogs by traditional news media. Based on the concepts of intermedia agenda setting and agenda building, this study explored the source interaction between 10 elite traditional news media and 10 political filter blogs during the 2006 Congressional Midterm Elections. An analysis of 2587 sources used in the election context found that traditional news media frequently cited blogs in their election coverage, but that the source attributions to the blogs were vague. Blogs, on the other hand, heavily cited traditional news media, but the analysis revealed that conservative blogs cited elite traditional news media less than did liberal blogs. Conservative blogs relied more on conservative media outlets in their election coverage. A case study of the dominant election topic, the Mark Foley scandal, showed that the daily interaction between the two media formats was driven by the use of breaking news elements as well as controversial opinions. The findings of this study show that the blog agenda is strongly influenced by traditional news media sources and that blogs at the same time have become part of the routine newsgathering process of traditional news media journalists. However, the findings also raise questions about changes in the standard journalistic research and attribution procedures as both media formats often rely on each other as sources rather than on original reporting.

Auf der Makroebene der Blogosphäre gibt es die sogenannten „A-Blogger“. Diese zeichnen sich dadurch aus, dass ihr Weblog (Blog) im Gegensatz zur großen Mehrheit der Blogs über sehr viele Inlinks-verfügt. In der Literatur sind verschiedene theoretische Ansätze zu finden, die sich mit der Frage beschäftigen, welche Funktion den A-Bloggern in der Blogosphäre zukommt. So wird beispielsweise davon gesprochen, dass sie eine Agenda-Setting-Funktion für die Blogosphäre einnehmen. Das bedeutet, dass sie die in der Blogosphäre diskutierten Themen vorgeben und somit die anderen Blogs, die über deutlich weniger Links verfügen, in deren Themenwahl beeinflussen. Anhand eines Datensatzes (Burton, Java et al. 2009) soll überprüft werden, ob eine Agenda-Setting-Funktion der deutschen A-Blogger für die deutschsprachige Blogosphäre bestätigt werden kann. Als Methode wird die Hyperlinkanalyse eingesetzt.

Diploma thesis Fashion blogs and research on the phenomenon discusses a relatively new phenomenon of personal blogs with a focus on fashion and style. It presents fashion blogs in all their complexity, including the definition, classification, origin and evolution. The second section compares the descriptive way fashion blogs with thematically related fashion magazines and from various perspectives: formal characteristics, work organization, text, picture and graphic elements, audiences, the use of advertising and PR and representation of reality. The practical part is focused on qualitative research fashion blog - by a focus group interview with fashion bloggers and subsequently grounded theory method of analysis examines the various relationships, especially causal, which operate under the studied phenomenon. Through reveals further aspects of the fashion blogging such as motivation, fears, needs, dreams and ambitions of bloggers. The goal is to answer the question of how fashion blogs with its distinctive style and authors presentation define the fashion magazines and propose a basic theory of operation of the medium as yet not explored.

The problem of the investigation consists in verifying, from the massive spread of the blog, in contemporary society, the relevance of its educational use. Blogs have evolved from the content publishing easiness in cyberspace, which allowed the exploration of this new means of communication for various types of audiences, such as teachers. This situation favored the growth of the use of blogs in the virtual space which gave rise the blogosphere, which was later overrun by new type of mercantilist speculation, the monetization of contents, which began to influence the production of blogs. We note that this is the situation pointed out by the authors of the critical theory of society, as a situation conducive to the spread of semiformation to the detriment of cultural formation able to contribute to citizenship development. Through such a situation, we make the following hypotheses about the pedagogical use of the blog: is suffering direct influence of monetization and undertakes pedagogical objectives; its origin oriented to the collective work contributes to the construction of knowledge; It can be a tool to build collective knowledge, in an interdisciplinary way and social value. Therefore our objectives were constituted in analyzing the relevance of the pedagogical use of the blog and its relation with the formation of basic education teachers; contextualize, the blog, the blogosphere and the influence they received from contents monetization; investigate how the blog contributes to the collective construction of knowledge; investigate the use of the blog as a content evaluation instrument, built collectively with interdisciplinary character and social value. Empirical research involves documentary analysis of four teacher’s blogs, themed focused on basic education. We observed that teachers, authors of the analyzed blogs, maintained their pedagogical praxis, even in a favorable environment for semiformation. Therefore we call them bloggers teachers, as analysis category that led us to confirm the hypotheses about the contribution to knowledge building interdisciplinary collectively and social value, but the hypothesis of the influence of monetization was not confirmed because the analyzed blogs did not observe its direct influence that compromise pedagogical objectives. / Esta investigación tiene como objeto el uso pedagógico del blog. El problema de la investigación es verificar, a partir de la difusión masiva del blog, en la sociedad contemporánea, la relevancia de su uso pedagógico. Los blogs han evolucionado a partir de la facilidad de la publicación de contenido en el ciberespacio, lo que permitió la exploración de este nuevo medio de comunicación para varios tipos de público, como los maestros. Esta situación ha fomentado el crecimiento del uso de los blogs en el espacio virtual que conducía al blogosfera, que más tarde fue invadida por nuevo tipo de especulación mercantilista, la monetización de contenido, que comenzó a influir en la producción de los blogs. Observamos que se trata de una situación señalado por los autores de la teoría crítica de la sociedad, como una situación propicia para la propagación de la semiformación en detrimento de la formación cultural que podría contribuir al desarrollo de la ciudadanía. En esta situación, hacemos las siguientes hipótesis acerca del uso pedagógico del blog: sufre la influencia directa de la monetización y se compromete los objetivos pedagógicos; su origen orientado al trabajo colectivo contribuye a la construcción del conocimiento; Puede ser una herramienta para construir conocimiento en colectivo, interdisciplinario y valor social. Así que nuestros objetivos se constituyeron para examinar la pertinencia del uso pedagógico del blog y su relación con la formación de maestros de nivel inicial; contextualizar, los blogs, la blogosfera y la influencia que recibieron de la monetización de contenidos; investigar cómo el blog contribuye a la construcción colectiva del conocimiento; investigar el uso del blog como una herramienta de evaluación de contenidos de forma colectiva con carácter interdisciplinario y el valor social. La investigación empírica comprende el análisis documental de cuatro blogs hechos por maestros, con temas centrados en la educación inicial. Se observó que los maestros, autores de los blogs analizados, mantienen su praxis pedagógica, incluso en un entorno propicio para la semiformación. Por lo tanto los llamamos de maestros blogueros, como una categoría de análisis que nos llevó a confirmar las hipótesis acerca de la contribución a la construcción del conocimiento interdisciplinario colectiva y valor social, pero la hipótesis de la influencia de la monetización no fue confirmada debido a que los blogs analizados no observa su influencia directa que comprometen los objetivos pedagógicos. / Esta pesquisa tem por objeto o uso pedagógico do blog. O problema da investigação consiste em verificar, a partir da disseminação massiva do blog, na sociedade contemporânea, qual a relevância de seu uso pedagógico. Os blogs evoluíram a partir da facilidade de publicação de conteúdos no ciberespaço, o que permitiu a exploração desse novo recurso de comunicação por vários tipos de públicos, como os professores. Tal situação favoreceu o crescimento da utilização de blogs no espaço virtual o que deu origem a blogosfera, que posteriormente foi invadida por nova modalidade de especulação mercantilista, a monetização de conteúdos, que passou a influenciar as produções dos blogs. Observamos tratar-se de fator apontado por autores da teoria crítica da sociedade, como situação propícia à propagação da semiformação em detrimento da formação cultural capaz de contribuir para o desenvolvimento da cidadania. Diante tal situação, elaboramos as seguintes hipóteses sobre a utilização pedagógica do blog: sofre influência direta da monetização e compromete objetivos pedagógicos; sua origem voltada ao trabalho coletivo contribui para a construção de conhecimento; pode ser instrumento de construção de conhecimento de forma coletiva, interdisciplinar e com valor social. Assim nossos objetivos se constituíram em analisar a relevância do uso pedagógico do blog e sua relação com a formação de professores de ensino básico; contextualizar, o blog, a blogosfera e a influência que receberam da monetização de conteúdos; investigar de que maneira o blog contribui para a construção coletiva de conhecimento; investigar o uso do blog como instrumento de avaliação de conteúdos coletivamente com caráter interdisciplinar e valor social. A pesquisa empírica envolveu análise documental de quatro blogs de professores, com temática voltada à educação básica. Observamos que os professores, autores dos blogs analisados, mantiveram sua práxis pedagógica, mesmo que em um ambiente propício à semiformação. Por isso os denominamos de professores blogueiros, como categoria de análise que nos levou à confirmação das hipóteses sobre a contribuição para construção de conhecimento de forma coletiva interdisciplinar e com valor social, porém a hipótese sobre a influência da monetização não se confirmou, pois nos blogs analisados não observamos sua influência direta que comprometesse objetivos pedagógicos.
