This thesis focuses on investigating learning occurring in a web-based community of foodservice professionals, which is informally structured and based on voluntary participation, using concepts from the "communities of practice" (CoP) (Wenger, 1998) paradigm. As an informal learning environment, the web-based community was investigated based on three planes (Rogoff, 1998): Community (i.e., how does learning occur in the web-based community?), Interpersonal (i.e., how does learning occur between participants of the web-based community?), and Individual (i.e., how does individual learning occur through participating in the web-based community?). / Under the umbrella of the online ethnographic approach, I applied mixed-method research combining multiple data sources (i.e., discussion transcripts, online survey, online interviews, ethnographic observation, and other documents) and analytical methods (i.e., descriptive framework for CoP, content analysis, transcript analysis, and descriptive statistics). / In terms of the community plane, the web-based community was explored by applying the descriptive framework for communities of practice consisting of observable and measurable indicators in terms of organization, participation, and outcome. With regard to the interpersonal plane, I explored how learning occurs between participants of the WBC: How do participants interact with each other and what do they share through their interactions? To do that, the processes of interaction and learning were examined according to the size of threads (i.e., small, medium, and large sizes). For the individual plane, I examined (a) individuals' epistemological beliefs and (b) individuals' change of roles in relation to the degree of participation. Based on the results investigated in each plane, I discussed general characteristics of this web-based community as informal learning environment, effective features fostering interaction and learning in this web based community, and possible trajectories of the web-based community evolving for a community of practice. / The importance of this study lies in its contributions to the conceptual framework (i.e., descriptive framework for communities of practice) and the methodological approach (i.e., multi-layered analytical approach) developed and applied in this thesis. The descriptive framework enables us to identify some defining features that distinguish communities of practice from other structures and hence to establish guidelines for monitoring how communities of practice evolve and what makes them evolve in successful ways. In addition, this study offers useful implications for designing and supporting web-based communities even in formal and non-formal learning environments. Because this study employed an exploratory, interpretive approach and concentrated on the breadth of learning in a web-based community through different planes, the results offer broader aspects of learning rather than specific, intensive issues of learning in this web-based community. Therefore, further studies are suggested along with the issues derived from this thesis.

Cette thèse doctorale, intitulée Discours antiféministes en ligne : une analyse impliquée et performative des matériaux textuels tirés du Web social au Québec, a pour objectif de cartographier des discours antiféministes diffusés sur le Web social au Québec en offrant une typologie originale. Dans un contexte socionumérique, cette thèse vise à concevoir comment les discours antiféministes peuvent être considérés ou non comme des violences faites aux femmes. S'intéressant à l'espace public numérique, l'analyse cible également comment les composantes structurantes des réseaux sociaux favorisent une telle prise de parole antiféministe. Au final, la thèse doctorale déploie les modalités de pouvoirs émanant des discours antiféministes partagés en ligne au Québec. L'étude repose sur une analyse de données impliquée et qualitative dont l'échantillonnage est tiré des réseaux sociaux au Québec entre les années 2014 et 2018. Deux catégorisations principales et originales ont été identifiées, soit les techniques de disqualification directes (injures objectivantes faites au corps, injures objectivantes faites à la sexualité, injures animalisantes et accusations de folie) et indirectes (accusation de misandrie, banalisation, caricature, accusation de radicalisme). Une variante de trois tons principaux (agressif, ironique et paternaliste) a été également ciblée. Les résultats de cette analyse doctorale permettent de cartographier les discours antiféministes en ligne, de concevoir le rôle des plateformes d'échange numérique dans la popularisation de ces propos, d'examiner la composante violente de cette rhétorique à travers des rapports de force qui s'en dégagent et d'approfondir la portée idéologique qui en découle. / The aim of the doctoral thesis Discours antiféministes en ligne : une analyse impliquée et performative des matériaux textuels tirés du Web social au Québec (Online Antifeminist Discourse: An Involved and Performative Analysis of Textual Materials from the Social Web in Quebec) is to map out the extent of antifeminist discourse across the social web in Quebec by offering an original typology. Few studies discuss the widespread antifeminist discourse that exists in social networks, particularly in Quebec. This analysis was therefore necessary given the lack of academic coverage on the topic. In a socio-digital context, it was essential to highlight how antifeminist discourse may or may not be considered violence against women. Focusing on public digital spaces, this thesis also targets how the structural components of social networks favour antifeminist speech. Ultimately this doctoral thesis demonstrates the power of widespread antifeminist language on social networks in Quebec. The analysis is based on an involved and qualitative analysis of sample data collected from social networks in Quebec between 2014 and 2018. Two main and original categories were identified, namely direct disqualification techniques (objectifying insults about one's body, objectifying insults about one's sexuality, animalizing insults, and insanity accusations) and indirect disqualification techniques (misandry accusations, trivialization, caricatures, and radicalism accusations). Three main tones (aggressive, ironic, and paternalistic) were also targeted. The results of this doctoral analysis are used to map online antifeminist discourse, consider the role of digital exchange platforms in the popularization of antifeminist speech, examine the violent aspect of this rhetoric through the power relations that emerge from it, and broaden the scope of resulting ideological factors.

The full transformational effects of Social Media have yet to be understood. Alongside its heavily discussed benefits, a number of potentially harmful effects have become apparent lately. Phenomena such as still increasing information overload, cyber-bullying, or loss of identity have been described in recent research literature from various domains. By means of a literature review our paper aims at reviewing, cataloguing and classifying these psychological and social disorders that have been reported to be related to Social Media engagement. We distinguish between active participation in and mere exposure to Social Media. Using a psychopathological classification scheme, we structure the identified symptoms and syndromes, providing a common language and taxonomy with which the identified disorders can be described and classified accurately. Thus, we are laying out a foundation necessary for the research into and the understanding of the aetiology and eventually the means for the prevention of the negative effects of Social Media usage within individuals in information societies.

Le Web social croît de plus en plus et donne accès à une multitude de ressources très variées, qui proviennent de sites de partage tels que del.icio.us, d’échange de messages comme Twitter, des réseaux sociaux à finalité professionnelle, comme LinkedIn, ou plus généralement à finalité sociale, comme Facebook et LiveJournal. Un même individu peut être inscrit et actif sur différents réseaux sociaux ayant potentiellement des finalités différentes, où il publie des informations diverses et variées, telles que son nom, sa localité, ses communautés, et ses différentes activités. Ces informations (textuelles), au vu de la dimension internationale du Web, sont par nature, d’une part multilingue, et d’autre part, intrinsèquement ambiguë puisqu’elles sont éditées par les individus en langage naturel dans un vocabulaire libre. De même, elles sont une source de données précieuses, notamment pour les applications cherchant à connaître leurs utilisateurs afin de mieux comprendre leurs besoins et leurs intérêts. L’objectif de nos travaux de recherche est d’exploiter, en utilisant essentiellement l’encyclopédie Wikipédia, les ressources textuelles des utilisateurs extraites de leurs différents réseaux sociaux afin de construire un profil élargi les caractérisant et exploitable par des applications telles que les systèmes de recommandation. En particulier, nous avons réalisé une étude afin de caractériser les traits de personnalité des utilisateurs. De nombreuses expérimentations, analyses et évaluations ont été réalisées sur des données réelles collectées à partir de différents réseaux sociaux. / The social Web grows more and more and gives through the web, access to a wide variety of resources, like sharing sites such as del.icio.us, exchange messages as Twitter, or social networks with the professional purpose such as LinkedIn, or more generally for social purposes, such as Facebook and LiveJournal. The same individual can be registered and active on different social networks (potentially having different purposes), in which it publishes various information, which are constantly growing, such as its name, locality, communities, various activities. The information (textual), given the international dimension of the Web, is inherently multilingual and intrinsically ambiguous, since it is published in natural language in a free vocabulary by individuals from different origin. They are also important, specially for applications seeking to know their users in order to better understand their needs, activities and interests. The objective of our research is to exploit using essentially the Wikpédia encyclopedia, the textual resources extracted from the different social networks of the same individual in order to construct his characterizing profile, which can be exploited in particular by applications seeking to understand their users, such as recommendation systems. In particular, we conducted a study to characterize the personality traits of users. Many experiments, analyzes and evaluations were carried out on real data collected from different social networks.

Esta tesis tiene un doble objetivo, por un lado, analizar las acciones organizativas, de formación docente y de uso pedagógico de la web social desarrolladas en las universidades españolas. Por otro lado, avanzar criterios que guíen el diseño e implantación de dinámicas de apoyo institucional, de desarrollo profesional docente y de aplicación metodológica de las herramientas 2.0 en las universidades españolas. Para alcanzar los objetivos anteriores, se han planteando cinco preguntas de investigación: 1. ¿Cuáles son los principales cambios organizativos que conducen al aprovechamiento educativo de la web 2.0 en la universidad? 2. ¿Cómo debe funcionar un servicio de asesoría técnico-pedagógica en el ámbito universitario? 3. ¿Cómo deben plantearse las ofertas de formación permanente del profesorado universitario sobre el uso didáctico de la web social? 4. ¿De qué modo tienen qué diseñarse las actividades educativas mediadas por el software social en las aulas universitarias? 5. ¿Qué roles “innovadores” deben desempeñar los docentes universitarios a la hora de aplicar una “pedagogía 2.0” en sus clases? Se ha seguido una aproximación metodológica mixta, para triangular los resultados en base a cuatro técnicas de investigación: 1) la entrevista a expertos en tecnología educativa(semiestructurada y en línea), 2) la observación participante realizada en el Educational Technology Services (UC Berkeley) y el proceso de diseño y desarrollo de una desconferencia (Cal Educamp 2011), 3) la observación no participante sobre las actividades educativas 2.0 señaladas por los docentes universitarios españoles y basada en la información obtenida en 4) el cuestionario en línea. A través del proceso de análisis se han establecido una serie de criterios que permitan consolidar la innovación educativa en las instituciones de tercer ciclo. Dichos criterios estimulan el cambio en las diferentes dimensiones y actores del proceso de enseñanza-aprendizaje, respecto a la implementación educativa de la web social. Los criterios establecidos a nivel instuticional buscan ayudar a desarrollar acciones organizativas, sistemáticas, estratégicas y de apoyo de la introducción de la web social dentro de las universidades. Estos criterios inciden en las actitudes de promoción de la integración pedagógica “en”, y “de” las TIC dentro de los organismos de gestión, política y organización universitaria. En cuanto a la formación docente y desarrollo profesional docente, los criterios fijados afectan a aquellas actividades que permiten reflexionar, diseñar y adaptar la formación continua del profesorado “en”, “sobre” y “con” las tecnologías sociales. En los procesos de enseñanza-aprendizaje desarrollados en las aulas los criterios expuestos se centran en promover el uso pedagógico adecuado de la web social, o su aplicación metodológica. La presente investigación quiere ayudar en el diseño y desarrollo de propuestas educativas orientadas a facilitar y mejorar los procesos de integración educativa de la web social en las facultades españolas. En este sentido, se espera que sirva de inspiración para consolidar universidades innovadoras promotoras de una educación de calidad e integral para todos los ciudadanos mediada a través de las tecnologías de la web social. / The purpose of this thesis is twofold analyze three dimensions developed in Spanish universities which are the organizational one, the teacher training, and the educational use within a social web context. Secondly, make an improvement of the criteria guiding the design and implementation of: dynamic institutional support, professional teacher development, and methodological application of Web 2.0 tools in Spanish universities. To achieve the above objectives, five research questions have been raised: 1. What are the major organizational changes that lead to educational use of Web 2.0 in universities? 2. How should work a technical and pedagogical assessment department service in the university? 3. How should offers concerning teacher training about the educational use of the social web be considered? 4. In which way have educational activities facilitated with social software to be designed in university classrooms? 5. What "innovative" roles must play university teachers in implementing a "pedagogy 2.0" in their classes? It has followed a mixed methodological approach to triangulate the results based on four research methods: 1) interviewing experts in educational technology (with semi-structured and online interviews), 2) participant observation conducted in the Educational Technology Services (UC Berkeley ) and process followed to design and develop an “unconference” (Cal EduCamp 2011), 3) non-participant observation on educational activities 2.0 reported by Spanish university teachers and based on information obtained in 4) the online questionnaire. Through the process of analysis a set of criteria to strengthen the educational innovation in tertiary institutions has been established. These criteria encourage the change in different dimensions and actors of the teaching-learning process, criteria linked to the educational implementation of the social web. The criteria developed at the institutional level seek to help to develop organizational, systematic, strategic and supporting actions for the introduction of the social web within the universities. These criteria affect attitudes to promote educational integration "in" and "of" ICT in managerial, political and organizational departments of universities. Regarding teacher training and teacher professional development, the fixed criteria which affect those activities that allow considering, designing and adapting teacher education "in" "on" and "with" social technologies. In the teaching-learning processes developed in classrooms, the criteria focus on promoting appropriate educational use of the social web, or its methodological application. This research wants to help the design and development of educational programs. These programs are aimed at facilitating and improving the educational integration of the social web in Spanish universities. In this sense, it is expected that consolidation will inspire innovative universities promoting quality and ease the comprehensive education for all citizens thanks to the social web technologies.
