L'utilisation des artefacts numériques pour la réalisation d'activités d'apprentissage reste le plus souvent individuelle, faute de disposer d'environnements adaptés, tant du point de vue du matériel que des applications et des pratiques pédagogiques. Cette recherche rend compte de l'expérience d'usages de différents artefacts dans une activité collaborative d'élaboration de cartes mentales et conceptuelles proposée en cours d'histoire de seconde. L'objectif principal est l'étude du rôle de l'espace de travail privé pour l'édition collective de cartes mentales et conceptuelles. Plus précisément, l'objectif est d'évaluer si le recours aux artefacts numériques lors de l'édition collective de cartes mentales et conceptuelles favorise les processus de confrontation cognitive constitutifs de la collaboration. Pour répondre à cet objectif, deux itérations (expérimentation pilote et expérimentation) ont été réalisées avec deux prototypes de dispositif numérique de collaboration qui permettent aux élèves de différencier leur espace de travail individuel de l'espace collectif. La première expérimentation pilote a été réalisée en 2015 avec un prototype de cartes mentales existant avant l'étude. Elle a consisté à valider le protocole expérimental de la recherche et à préciser les questions de recherche et les hypothèses. La deuxième expérimentation, quant à elle, a été réalisée au cours de l'année 2016 via un prototype de cartes conceptuelles conçu et développé dans le cadre de cette recherche. Cette expérimentation a eu pour but d'éprouver les trois hypothèses formulées, qui s'inscrivent dans la théorie de l'apprentissage social de Bandura (1980) et portent à la fois sur des déterminants environnementaux, cognitifs et comportementaux. La première hypothèse (déterminants environnementaux) suppose tout d'abord que la médiation instrumentale d'une activité d'apprentissage collaborative a une influence sur la participation des élèves. La deuxième hypothèse (déterminants cognitifs) quant à elle, soutient que l'adjonction d'un espace de travail personnel de l'élève à un espace d'interaction collectif favorise des processus cognitifs présents dans la collaboration : le conflit sociocognitif (Doise et Mugny, 1997; Perret-Clermont, 1979), l'étayage (Bruner, 1997) et la vicariance (Bandura, 1980; Pentland, 2015). Enfin, la troisième hypothèse (déterminants comportementaux) suggère que la participation individuelle des élèves sur l'élaboration d'une carte conceptuelle collective est influencée par la culture affective du groupe. Afin de vérifier ces 3 hypothèses, un plan expérimental multifactoriel croisé a été mis en place, ce qui a permis de tester les variables indépendantes simultanément auprès de 7 groupes de lycéens de seconde en classe d'histoire. L'analyse de données effectuée est centrée sur la nature des interactions orales et numériques des élèves, ainsi que sur leurs productions écrites et leurs réponses aux entretiens collectifs et aux questionnaires individuels. Les résultats montrent la tendance du dispositif numérique de collaboration (artefacts, organisation de l'activité, scénario pédagogique) à favoriser le processus d'étayage et vicariance suite aux échanges nécessaires à la coordination des tâches techniques d'édition de la carte conceptuelle. Les résultats indiquent qu'après l'utilisation d'un espace privé numérique, les élèves ont des conflits sociocognitifs significatifs lors du travail en groupe, les entraînant à accepter les réponses les plus ouvertes afin d'éviter la confrontation. / The use of digital artifacts for learning activities usually remains individual, as there are no suitable environments, from the point of view of materials, applications and teaching practices. This research reports on the experience of using different artefacts in a collaborative activity to elaborate mental and conceptual maps proposed in a history class in the eleventh grade. The aim is to study the role of a private workspace for the collective edition of mental and conceptual maps. More specifically, the goal is to assess whether the use of digital artifacts in the collective edition of mental and conceptual maps promotes the processes of cognitive confrontation that constitutes collaboration. To meet this objective, two iterations (pilot experimentation and experimentation) were carried out with two digital collaborative prototypes that allow students to differentiate their individual workspace from the collective space. The first pilot experiment was conducted in 2015 with a prototype of mental maps existing prior to the study. It consisted of validating the experimental protocol of the research and clarifying research questions and hypotheses. The second experiment, meanwhile, was carried out in 2016 via a prototype of concept maps designed and developed as part of this research. The purpose of this experiment was to test the three hypotheses formulated, which fit into Bandura's (1980) theory of social learning and address environmental, cognitive and behavioral determinants. The first hypothesis (environmental determinants) assumes that the instrumental mediation of a collaborative learning activity has an influence on the student participation. The second hypothesis (cognitive determinants), for its part, argues that the addition of a personal workspace of the student to a collective interaction space favors cognitive processes present in collaboration: sociocognitive conflict (Doise and Mugny Perret-Clermont, 1979), supporting (Bruner, 1997) and vicariance (Bandura, 1980, Pentland, 2015). Finally, the third hypothesis (behavioral determinants) suggests that the individual participation of pupils in the elaboration of a collective concept map is influenced by the affective culture of the group. In order to verify these 3 hypotheses, a crossed multifactorial experimental plan was put in place, which made it possible to test the independent variables simultaneously with 7 groups of high school students in history class. The data analysis carried out focuses on the nature of students' oral and digital interactions, as well as their written outputs and their responses to group interviews and individual questionnaires. The results show the trend of the digital collaboration device (artifacts, organization of the activity, pedagogical scenario) to favor the supporting and vicariance process as an explanation of the exchanges needed to coordinate the technical tasks of editing the concept map. The results indicate that after using a digital private space, pupils have significant sociocognitive conflicts during group work, leading them to accept the most open responses in order to avoid confrontation. / El uso de artefactos digitales para la realización de actividades de aprendizaje sigue siendo principalmente individual, por falta de entornos adecuados, desde el punto de vista del material, de las aplicaciones y de las prácticas pedagógicas.

La segunda hipótesis (determinantes cognitivos), por su parte, sostiene que la adición de un espacio de trabajo personal del alumno a un espacio de interacción colectivo promueve procesos cognitivos presentes en la colaboración: el conflicto socio-cognitivo (Doise y Mugny Perret-Clermont, 1979), el apoyo (Bruner, 1997) y la vicarianza (Bandura, 1980, Pentland, 2015). Finalmente, la tercera hipótesis (determinantes conductuales) sugiere que la participación individual de los alumnos en la elaboración de un mapa conceptual colectivo está influenciada por la cultura afectiva del grupo. Para verificar estas 3 hipótesis, se puso en marcha un plan experimental multifactorial cruzado, que permitió probar las variables independientes simultáneamente con 7 grupos de estudiantes de cuarto de secundaria en la clase de historia. El análisis de datos realizado se centra en la naturaleza de las interacciones orales y digitales de los estudiantes, así como en sus resultados escritos y sus respuestas a entrevistas grupales y cuestionarios individuales. Los resultados muestran la tendencia de los dispositivos digitales de colaboración (artefactos, la organización de la actividad, escenario pedagógico) a promover el proceso de apoyo y vicariedad tras las conversaciones necesarias para coordinar las acciones técnicas para publicar en el mapa conceptual. Los resultados indican que después de usar un espacio privado digital, los estudiantes tienen conflictos sociocognitivos significativos durante el trabajo en grupo, lo que los lleva a aceptar las respuestas más abiertas para evitar el enfrentamiento.

Online adolescent friendships and social networking among adolescents are current phenomena that have emerged, and exploded, as part of the digital age and the vast development of communication technologies. The primary aim of this study was to gain knowledge and understanding regarding the nature and quality of online friendships and social networking among adolescents. A sequential explanatory mixed method design, was put to use for the purpose of this study. The quantitative data was collected first in the form of a short survey, by utilising a self-developed questionnaire to obtain a general overview of the social network practices and the forming and maintaining of online friendships among adolescents. Twenty five participants took part in the survey. This study was followed by a qualitative study in the form of interviews, to clarify, elaborate and explain the quantitative findings. Five information rich participants were interviewed. The findings of the empirical investigation revealed that adolescents, being part of the Net Generation, base their concept of socialising with friends on digital and communication technology, especially cell phones. They are connected to their friends 24 hours a day. The sense of safety and support they experience through this constant connectedness strengthens their self-esteem, self-confidence and self-worth and contributes to their identity formation. It is therefore recommended that parents and educators should accept that adolescents live in a virtual world and their new way of socialising, needs to be acknowledged. Parents and educators should adjust accordingly, by getting educated in this field themselves. The Net Generation is a generation who focuses on relationships and collaboration through technology and this should be exploited by anybody who has contact or interacts with the adolescent of today. / Psychology of Education / M.

The researcher investigated internet usage among students at the University of Nairobi using a quantitative case study method. A questionnaire-based survey was done among 381 students and face-to-face interviews were conducted with the university‟s library staff. The research findings indicate that the students' level of awareness about the internet services offered at the university was high. The students had good basic computer and internet skills; however, they lacked more advanced skills and this negatively affected their use of internet resources. The students used the internet for various purposes, including to study, teach and do research; to communicate; and for social interaction. The major recommendations of the study include providing formal internet training and adequate facilities; implementing a better, inclusive policy on internet use; and better co-ordinated university efforts. Free internet access should be made available to all the university students, if not all members of the university community. / Information Science / M.A. (Information Science)

In the digital domain, virtual teams within organizations and corporations are becoming common. Restructuring an organization or corporation is vital because competition and globalization are increasing. In this era of globalization, distributed working groups need to develop a competitive advantage in these ever-changing environments. Historically, teams had experienced problems stemming from geographical and temporal limitations. With the increase of technology in telecommunications, organizations are increasingly forming virtual teams, which have become critical to the survival of nearly any corporate entity. Virtual teams have some of the same problems that regular teams have. One of the key challenges is the method of forming teams, while such challenge is exacerbated in digital environments. Despite the difficulties, the digital environment has made successful team development all the more challenging. The variation in people's skills makes the formation of teams even more difficult. This is why organizations cannot determine in advance if a virtual team will be a success. To evaluate the success of team formation in a virtual setting, this research study assessed the role of different computer-mediated communications (CMC) levels employed (no-CMC/face-to-face, online learning system, online learning system + social networking site) on the success of team formation measured by the level of task performance (TP), team cohesiveness (TC), computer skills (CS) and social bond (SB), while assessing the differences on such relationships when controlled for demographic information such as gender, age, education level, academic major, as well as academic year. Empirical data was collected from students at the Medical Sciences Campus in the University of Puerto Rico with 140 usable records. Using three teams and 140 participants, the results indicated that there is a statistically significance difference in the role of CMC levels employed (no-CMC/face-to-face, online learning system, online learning system + social networking site) on the level of perception of CS in team formation. Significant differences were also found in the role of CMC levels employed on the levels of TP, when controlled for gender. In addition, there is a significance difference in the role of CMC levels employed (no-CMC/face-to-face, online learning system, online learning system + social networking site) on the levels of CS, when controlled for education, academic major and academic year. The outcomes of the study contributed to the body of knowledge for both practice and research, to help organizations identify ways to support effective team formations in virtual environments.

Ce mémoire examine l'adoption des téléphones mobiles et l'utilisation des messages texte (SMS) par les adolescents chinois, selon la théorie des usages et gratifications et de la recherche sur la communication par ordinateur. Certains champs particuliers de l'utilisation des messages textes par les adolescents chinois, comme le contrôle parental, la circulation des chaînes de messages, la popularité des messages de salutations et l'utilisation répandue des émoticônes ont été étudiés. La fonction sociale des SMS, plus particulièrement des pratiques sociales et des relations émotionnelles des adolescents chinois, a également été explorée. Cette étude est basée sur un sondage réalisé sur le terrain auprès de 100 adolescents chinois. Elle révèle que chez les adolescents chinois, les deux principales raisons pour l'adoption du téléphone mobile sont l'influence parentale et le besoin de communication sociale. Quant à l'utilisation des messages texte, elle répond à sept usages et gratifications : la flexibilité, le coût modique, l’intimité, éviter l'embarras, le divertissement, l'engouement et l'évasion. Il a également été observé que les messages texte jouent un rôle positif dans la construction et l'entretien des relations sociales des adolescents chinois. / This thesis examined the adoption of mobile phones and use of SMS among Chinese teenagers based on the uses and gratification theory and computer-mediated communication research. Specific areas of Chinese teenagers’ SMS use, such as parental control, the circulation of chain messages, the popularity of greeting messages and the wide use of emoticons were studied. The social functions of SMS, especially in Chinese teenagers’ social-emotional practice, were explored as well. This study is based on a field survey conducted among one hundred Chinese teenagers. It reveals that, for Chinese teenagers, the two main reasons for the adoption of mobile phones are parental influence and the need for social communication; the use of SMS corresponds to seven uses and gratifications: flexibility, low cost, privacy, embarrassment avoidance, entertainment, fad and escape. SMS is also used by Chinese teenagers to build and maintain their social relationships.

Ce mémoire présente les recherches et réflexions entourant la conception d’une application à base d’ontologie dédiée au e-recrutement dans le domaine des services de dotation de personnel en technologies de l’information à l’ère du Web Social. Cette application, nommée Combine, vise essentiellement à optimiser et enrichir la Communication Médiée par Ordinateur (CMO) des acteurs du domaine et utilise des concepts issus du paradigme technologique émergent qu’est le Web sémantique. Encore très peu discuté dans une perspective CMO, le présent mémoire se propose donc d’examiner les enjeux communicationnels relatifs à ce nouveau paradigme. Il présente ses principaux concepts, dont la notion d’ontologie qui implique la modélisation formelle de connaissances, et expose le cas de développement de Combine. Il décrit comment cette application fut développée, de l’analyse des besoins à l’évaluation du prototype par les utilisateurs ciblés, tout en révélant les préoccupations, les contraintes et les opportunités rencontrées en cours de route. Au terme de cet examen, le mémoire tend à évaluer de manière critique le potentiel de Combine à optimiser la CMO du domaine d’activité ciblé. Le mémoire dresse au final un portrait plutôt favorable quant à la perception positive des acteurs du domaine d’utiliser un tel type d’application, et aussi quant aux nets bénéfices en frais d’Interactions Humain-Ordinateur (IHO) qu’elle fait miroiter. Il avertit toutefois d’une certaine exacerbation du problème dit « d’engagement ontologique » à considérer lors de la construction d’ontologies modélisant des objets sociaux tels que ceux dont le monde du recrutement est peuplé. / This thesis presents the research and reflections on the development of an ontology based application dedicated to e-recruitment in the field of Information Technologies’ staffing services, and especially e-recruitment using Social Web platforms as sources for candidates. This application, called Combine, essentially aims to optimize and enhance the field recruiters’ Computer-Mediated Communication (CMC) and uses concepts from the emerging technological paradigm that the Semantic Web represents. Rarely discussed in a CMC perspective, this submission therefore proposes to study the communications issues related to this new paradigm. It presents the main concepts, as the notion of ontology, which involves the formal modeling of knowledge, and outlines the development case of Combine. It describes how the system was designed, from the requirements analysis to the prototype evaluation, revealing the concerns, the constraints and the opportunities met along the way. After this examination, the thesis stretches out to critically assess Combine’s potential to optimize the CMC in the targeted field of activity. In the end, the thesis conveys a rather favorable outcome concerning the positive perception of the field recruiters about using this type of application, and also concerning the promising benefits in Human-Computer Interactions (HCI). However, it mentions as well the exacerbation of the problem called "ontological commitment", which is to consider when building ontologies that model social objects such as those which the world of recruitment is made of.

With an increasing proportion of older people in the Australian population and increasing health and longevity, paid work after the age of 65 years may become an option or a necessity in the future. The focus of this research is on Australian women of the baby boom generation, their working futures, and the work-retirement decision. This is explored both from the viewpoint of women and from a social policy perspective. The research draws on Considine�s model of public policy, futures studies, and Beck�s concept of risk society. The research comprises three studies. Using focus group research, Study 1 explored the views of Australian women of the baby boom generation on work after the age of 65 years. Study 2 aimed to explore current thinking on the research topic in Australia and overseas. Computer-mediated communication involving an Internet website and four scenarios for the year 2020 were used for this study. Study 3 consists of the analysis of quantitative data from the Healthy Retirement Project, focusing on attitudes towards retirement, retirement plans, and the preferred and expected age of retirement. The importance of choice and a work � life balance emerged throughout the research. Women in high-status occupations were found to be more likely to be open to the option of continuing paid work beyond age 65 than women in low-status jobs. However, the women were equally likely to embrace future volunteering. The research findings suggest that policies for an ageing female workforce should be based on the values of inclusiveness, fairness, self-determination, and social justice, and address issues of workplace flexibility, equality in the workplace, recognition for unpaid community and caring work, opportunities for life-long learning, complexity and inequities of the superannuation system, and planning for retirement. Further, providing a guaranteed minimum income for all Australians should be explored as a viable alternative to the current social security system.

自一九八Ｏ年代起，現代資訊與通訊科技(Information and Communication Technology or ICT)、電腦中介傳播(Computer-Mediated Communication or CMC)、網際網路(Internet)及全球資訊網(World Wide Web or WWW)的發展和普及化，已被學者、政治人物、以及論者們認為是可用以加強實踐公民參與及民主政治之有效工具。本研究即探討政府如何透過網際網路來提供公民參與機制。 本研究以網際網路之公民參與機制的理論為基礎，建構一個完整的網際網路之公民參與機制，亦即建構一個理想的網路公共論壇版面。並檢視台北市政府於全球資訊網網站上之公共論壇版面的運作現況及其成效，檢驗其中公民參與公共事務價值的實踐程度。最後，將探討網際網路之公民參與機制的實踐會有哪些侷限，應如何加以突破，藉此提供學術界及實務界研究貢獻。 / Since the 1980's, many scholars, statesmen, and researchers have come to realize that the development and popularity of modern Information and Communication Technology (ICT), Computer-mediated Communication (CMC), Internet, and the World Wide Web (WWW) will become the effective mechanism for citizen participation. The main purpose of this research paper is to study how government provides citizen participation through Internet. First, the paper will take the theory of Internet citizen participation to construct an ideal mechanism of Internet citizen participation, i.e., to build an ideal operational procedural of Internet Public Forum. Second, the paper will use Taipei City Government's "Citizen Forum" in the World Wide Web as a case study to compare and analyze this case with the ideal operational procedural of Internet Public Forum. Last, the paper will discuss the constraints of Internet citizen participation, and search for solutions to these constraints.

社交網站，尤其是Facebook，在近幾年使用人口日趨增加，變得非常熱門。本研究觀察到在組織內，許多人運用Facebook這類社交網站與同事維繫人際關係。有趣的是，當Facebook進入組織情境後，這種以電腦中介傳播為基礎的人際互動方式，與實體人際關係模式不同，也迥異於全然線上的人際互動模式，其特殊性進一步帶來組織內人際關係的重要改變。 　　本研究共分三方面來探討Facebook進入組織情境後，對組織內人際關係所造成的改變。首先，受Facebook科技屬性影響，組織成員在Facebook上人際關係樣態根基於「虛實交錯」此一概念。由於同事間相互認識，其人際關係發展歷程從線下的實體互動開始，蔓延到Facebook的線上互動，而眾人在線上互動結果又會再度影響實體關係。換句話說，組織成員在「虛擬」和「實體」不同場域來回擺盪，造成「虛實交錯」情形，也讓組織內人際關係模式產生改變。 　　在這基礎上，本研究進一步發現Facebook「虛實交錯」的人際關係模式展現在兩個層面上。從整體角度來看，當Facebook出現後，在組織內形成另一個人際關係場域，彷彿是辦公室內的「線上茶水間」，組織成員在該場域互動、維繫人際關係的方式與實體茶水間有所不同，有其獨特性，因此我們用「線上茶水間」來描繪Facebook「虛實交錯」下的人際關係場域特性。在線上茶水間，組織成員以大量且多樣化資訊做為連結人際關係基礎，達到不同於實體茶水間的社交功能，如大量且速成的安慰與支持、跨越時空的陪伴感等，也使得線上茶水間的人際關係具有一定特色，例如淺層情感交流等。從個人層次來探討，組織成員的形象在此人際關係場域內也有不同展現方式，當Facebook出現後，它的科技屬性提供組織成員「另一個舞台」，讓個人得以展現出在正式組織場域中難以呈現的某種形象，因此我們用「另一個舞台」來描繪其轉變與特性。然而Facebook終究位於組織體系內，因此組織成員無法扮演一個全新或不真實形象，在舞台上的「演出」難免受到束縛。儘管如此，組織成員仍可透過Facebook調節自己在實體組織場域予人的形象，展現出欲呈現面貌。 / This study discusses the impact and influence of Facebook on interpersonal relationships at the work place. Social networking sites (SNS), Facebook in particular, have grown in popularity in recent years. In addition to personal usage, many use Facebook as a tool to interact with their colleagues in corporate settings. When used in this manner, the mode of interaction is based on computer-mediated communication (CMC), which is distinct from physical interactions or from virtual online interactions. This study focuses on three aspects of Facebook that influence and shape the relationships among employees in a corporation. Firstly, the members of a business organization know each other, so the process of interaction begins with physical acquaintance. The interaction then migrates online through Facebook, which, in turn, shapes the nature of the physical interaction. In other words, aided by technology, the corporate personnel interact both in "virtual (online)" space and in "physical" space, resulting in a mode of interaction that can be called "virtually and physically interlaced" interaction. On this basis, this study examines the effects of "virtually and physically interlaced" interaction from two perspectives. First, from the overview perspective, the introduction of Facebook in a corporate setting creates a space for a new form of interaction, an "online break room" of sorts, in which the corporate personnel's interaction is experienced differently than in a physical break room. Employees in "online break rooms" communicate with each other in multiple modes and methods such as videos, music, forwarded articles and so on. Unlike in a physical break room where the conversations are limited in number and also limited by the necessity of shared space and time, the online break room offers unconstrained space where employees can readily exchange their thoughts, opinions, as well as their feelings with others. The experience creates a new social dimension to the "online break room" at hand that employees can be accompanied by colleagues anytime and anywhere and also be able to receive much comfort and support from the coworkers. However, the level of communication remains superficial because employees do not interact in person. Second, from the individual perspective, an employee's experience of interaction with others in an "online break room" is changed. The introduction of Facebook in a corporate setting provides its personnel an alternate platform to express themselves more personally, in ways which may have been difficult to do in a rigid and formal business environment. We use the term "alternative stage" to describe the changes in interactions afforded by the addition of another platform. On the "main stage" of a conventional corporate environment, a person may feel compelled to conform to the corporate culture, and the expression of individuality may be limited, which results in a projected image that tends to be formal. In such an environment, Facebook becomes a stage/place where individuals can express and highlight their own personality or hobbies, giving a more personal and informal image to adjust the physical and conventional formal images.
