Full textAbstract:
Les technologies de communication et d'information pénètrent et provoquent des changements dans tous les aspects de l'activité économique tout en véhiculant un nouveau sens d'une société en réseaux de plus en plus débarrassée des contraintes espace/temps. L'objet de la thèse est de démontrer la double dialectique de la révolution de l'information en cours, aussi bien pour ce qui est de sa diffusion que pour ses finalités dans les pays en développement. Dans ce sens, la première démonstration consiste à élucider les divergences entre les mécanismes objectifs et subjectifs d'une réception active et maîtrisée de ces technologies et la réalité de leur diffusion qui prend peu en compte leur appropriation pérenne et autonome par les populations des pays en développement. La seconde dialectique, celle des finalités s'intéresse d'une part aux potentialités pratiques des applications de ces techniques dans les secteurs de développement durable (exemple : éducation, santé et agriculture ) et dans certains aspects de la structure économique et sociale des pays en développement ( exemple: tourisme, médias et questions de genre). D'autre part, les finalités prescrites par la logique de la libéralisation économique et de la mondialisation imposent aux pays en développement de se conformer à des contraintes juridiques et économiques spécifiques. A cet égard, l'examen préalable de la notion de la fracture numérique s'avère nécessaire. Le problème central relatif à ce débat consiste à dégager la véritable signification de cette notion et à considérer son instrumentalisation par les organisations internationales et les multinationales afin d'imposer des applications particulières (exemple : téléservices) qui consacrent une insertion subalterne de ces pays dans la nouvelle division internationale du travail. L'utilité réelle des TIC dans une optique de développement ne se situe pas dans une course au rattrapage technologique selon les standards et mesures des pays développés. Elle est conditionnée par la mise en place sur le long terme d'une politique d'innovation ascendante (adoption, adaptation et création) qui sera basée en priorité sur la construction des capacités humaines, gage d'intégration dans la nouvelle économie du savoir mondialisée.

Esta tesis contribuye a varios campos del conocimiento. Primero, en ella se estudia el efecto ambiguo que la tecnología de Internet tiene en la estructura de costes de transacción en el caso de las ventas al por menor. En segundo lugar, esta tesis estudia empíricamente que factores determinan la adopción de la tecnología de Internet y la telefonía celular a nivel mundial desde 1980. Se demuestra que las diferencias entre países están determinadas en gran medida por el clima de inversión que afecta los incentivos de adoptar tecnologías basadas en activos específicos. Finalmente de desarrolla y pone a prueba una teoría que relaciona los sistemas electorales y las configuraciones de gobierno con la protección de los derechos de propiedad. Se propone un modelo, que establece una relación negativa entre el número de instituciones de toma de decisión consensual y el grado de protección de los derechos de propiedad.This research contributes to several fields of knowledge. It studies the ambiguous effects that the Internet has on the transaction costs structure in the case of retailing. Next, it presents an empirical study of the determinants of worldwide Internet and cellular phone penetration levels since 1980. It is shown that cross-country differences in the use of information and communication technologies (ICT) are to a considerable extent due to differences in investment climate, which determines the incentives to adopt technologies based on site-specific assets. Finally, this thesis develops and tests a theory regarding the effect that electoral formats and government configurations have on the degree of property rights protection. A formal model is presented, which establishes a negative relationship between the number of institutions of consensual collective decision-making and the degree of property rights protection.

This paper gives an account of themes that emerged from a preliminary analysis of a large corpus of electronic communications in an online, mediated course for intercultural learners. The goals were to test assumptions that electronic communication is internationally standardized, to identify any problematic aspects of such communications, and to construct a framework for the analysis of electronic communications using constructs from intercultural communications theory. We found that cyberspace itself has a culture(s), and is not culture-free. Cultural gaps can exist between individuals, as well as between individuals and the dominant cyberculture, increasing the chances of miscommunication. The lack of elements inherent in face-to-face communication further problematizes intercultural communications online by limiting opportunities to give and save face, and to intuit meaning from non-verbal cues. We conclude that electronic communication across cultures presents distinctive challenges, as well as opportunities to course planners.

Full textAbstract:
A conceptual model with wireless and mobile techniques is developed in this thesis for remote real-time condition monitoring, which is applied for monitoring, diagnosing, and controlling the working conditions of machines. The model has the following major functions: data acquisition, data processing, decision making, and remote communication. The data acquisition module is built up within this model using the sensory technique and data I/O interfaces to acquire the working conditions data of a machine and extract the physical information about the machine (e.g. failure, wear, etc.) for data processing and decision making. The data processing is conducted using digital conversion and feature extraction to process the received analogue condition data and convert the data into the physical quantities of working condition of the machine for sequent fault diagnosis. A real-time fault diagnostic scheme for decision-making is applied based on digital filtering and pattern classification to real-time identify the fault symptom of the machine and provide advice for decision making for maintenance. Process control is implemented to control the operation status of the machine automatically, inform the maintenance personnel diagnostic results and alert the working conditions of the machine. Remote communication with wireless and mobile features greatly advance the machine’s condition monitoring technology with real-time fault diagnostic capacity, by providing a wireless-based platform to enable the implementation of data acquisition, real-time fault diagnosis, and decision making through the Internet, wireless, and mobile phone network. The model integrating above techniques and methods has been applied into the following three areas: (1) Development of a Remote Real-time Condition Monitoring System of Industrial Gearbox, supported by the Stimulation Innovation Success programme (2007-2008); (2) Development of a Remote Control System of Solid Desiccant Dehumidifier for Air Conditioning in Low Carbon Emission Buildings, supported by the Sustainable Construction iNET programme (2009-2010); (3) Development of an Innovative Remote Monitoring System of Thermo-Electric-Generations, supported by the Sustainable Construction iNET programme (2010-2011). The combination of wireless and mobile techniques with data acquisition, real-time fault diagnosis, and decision-making, into a model for remote real-time condition monitoring is a novel contribution to this area.

lt;p align="justify"gt; A utilização de novas tecnologias e o uso de computadores conectados à Internet estão presentes em todos os segmentos da sociedade. Esta presença tem transformado, irreversivelmente, a forma como as pessoas pensam, agem e se relacionam com as outras. Essas mudanças provêm da rapidez com que são disponibilizadas e processadas as informações. O comunicar parece interconectar e aproximar indivíduos, fazendo aflorar percepções e situações vividas no cotidiano, que podem interferir na prática escolar. Dessa forma, esse estudo envolveu adolescentes que têm acesso a esses novos equipamentos, os quais têm influenciado na maneira de se comunicar e informar dentro e fora da escola. Portanto, sua implicação, no contexto escolar, foi analisada nesta pesquisa, cujos sujeitos investigados foram alunos do Ensino Médio de uma escola particular. O objetivo foi o de investigar a influência das novas tecnologias (computador e Internet) no cotidiano dos adolescentes e sua utilização no processo educacional. Foi utilizado, como instrumento de pesquisa, um questionário, aplicado aos adolescentes. Dentre as questões de estudo tivemos: a Internet e o computador são considerados ferramentas a serviço do conhecimento? Como é que vem sendo utilizada a Internet pelos adolescentes, e como a utilizam na educação? Após a análise dos dados, foi possível observar que: os adolescentes percebem a utilização do computador e da Internet como fonte de informação e sua utilidade como pesquisa. No que diz respeito à indagação da utilização do computador e da Internet como forma de aproximar ou afastar as pessoas do meio ambiente, os adolescentes, em maior percentual, enfatizaram que essas tecnologias afastam as pessoas do meio ambiente, pois o equipamento causa vício para aqueles que não têm um autocontrole de sua utilização, distanciando do meio ambiente natural. Finalizando, os adolescentes percebem as novas tecnologias como ferramenta a serviço do conhecimento.lt;/pgt;lt;p align="justify"gt; The use of new technologies and the use of connected computers to the Internet are present in all of the segments of the society. This presence has been irreversibly transforming the form as the people think, they act and they link with the other ones. Those changes come from the speed that they are made available and the information processed. Communicating seems to interconnect and to approximate individuals making to level perceptions and situations lived in day-to-day that can interfere in school practice. In that way, this study involved teenagers that have access to those new equipments which have been influencing in the way of communicating and informing inside and out of the school. Therefore, its implication, in the school context, it was analyzed in this research, whose investigated subjects were students of the Medium Teaching Level of a private school. The objective was to investigate the influence of the new technologies (computer and Internet) in the day-to-day of the teenagers and their use in the education process. It was used, as research instrument, a questionnaire, applied to the teenagers. Among the study subjects we had: are the Internet and the computer considered tools to service of the knowledge? How is it that the Internet has been used by the teenagers, and how do they use it in the education? After the data analysis, it was possible to observe that: the teenagers notice the use of the computer and the Internet as source of information and its usefulness as research. In what it concerns to the inquiry of the use of the computer and of the Internet as form of to approximate or to move away the people of the environment, the teenagers in larger percentage emphasized that those technologies move away the people of the environment, because the equipment causes addiction for those that don't have a self-control of its use distancing of the natural environment. Concluding, the teenagers notice the new technologies as tool to service of the knowledge.lt;/pgt;

This study aimed to explore adolescents perceptions of how their use of information and communication technologies may impact on the quality of the parent-adolescent relationship. Obtaining information from adolescents on how they experience their parents interaction with them when they engage with theses technologies, can provide insight into adolescents perceptions of whether information and communication technologies impact on this relationship. This research therefore aimed to explore the way that parents interact with their adolescents on their use of the Internet, gaming activities, or regulating their use of a cell phone, and how this is perceived by adolescents.

Full textAbstract:
L'école se préoccupe de la transmission de savoirs qui ne se réfèrent pas tous à des corps de savoirs savants constitués, comme ceux des mathématiques, par exemple. Il en est ainsi de la recherche d'information via Internet qui prend une place grandissante dans de nombreuses pratiques sociales. Dans cette perspective, un enseignement de la consultation d'information a été introduit dans les programmes de technologie de la classe de 4e. La thèse a pour objet d'examiner la question des savoirs à transmettre et de l'organisation des modes de transmission-appropriation de ce nouvel objet d'enseignement. La consultation d'information relève d'une activité humaine qui s'organise autour de l'usage, et donc de l'instrumentalisation d'un outil. Nous connaissons la faiblesse des apprentissages fondés sur la seule maîtrise opératoire. Examiner les enjeux de la transposition didactique à partir de pratiques, suppose donc de s'extraire d'une approche exclusivement procédurale, pour, dans un premier temps, examiner la question de l'élaboration de savoirs experts en nous appuyant sur la genèse instrumentale et à partir d'analyse de pratiques. Dans un second temps, nous nous sommes intéressés au processus d'enseignement apprentissage. L'observation d'élèves nous a permis, au travers de leurs conceptions, de mesurer la distance qui sépare leurs pratiques de consultation d'information de celles d'experts et ainsi de qualifier les enjeux de l'apprentissage. L'analyse du travail des enseignants permet d'identifier les modes de transmission qu'ils utilisent pour cet enseignement et donc d'anticiper sur les probables difficultés des élèves. Ainsi, le croisement de ces analyses nous permet de qualifier le processus de transmission-appropriation d'un corpus de savoirs particuliers liés à la consultation d'information via Internet et, au final, de penser des aides au travail des enseignants dans une perspective d'ingénierie didactique.

Full textAbstract:
This dissertation studies the effects of Information and Communication Technologies (ICT) on the banking sector and the payments system. It provides insight into how technology-induced changes occur, by exploring both the nature and scope of main technology innovations and evidencing their economic implications for banks and payment systems. Some parts in the dissertation are descriptive. They summarise the main technological developments in the field of finance and link them to economic policies. These parts are complemented with sections of the study that focus on assessing the extent of technology application to banking and payment activities. Finally, it includes also some work which borrows from the economic literature on banking. The need for an interdisciplinary approach arises from the complexity of the topic and the rapid path of change to which it is subject.The first chapter provides an overview of the influence of developments in ICT on the evolution of financial services and international capital flows. We include main indicators and discuss innovation in the financial sector, exchange rates and international capital flows. The chapter concludes with impact analysis and policy options regarding the international financial architecture, some monetary policy issues and the role of international institutions.
The second chapter is a technology assessment study that focuses on the relationship between technology and money. The application of technology to payments systems is transforming the way we use money and, in some instances, is blurring the definition of what constitutes money. This chapter surveys the developments in electronic forms of payment and their relationship to the banking system. It also analyses the challenges posed by electronic money for regulators and policy makers, and in particular the opportunities created by two simultaneous processes: the Economic and Monetary Union and the increasing use of electronic payment instruments.
The third chapter deals with the implications of developments in ICT on relationship banking. The financial intermediation literature explains relationship banking as a type of financial intermediation characterised by proprietary information and multiple interactions with customers. This form of banking is important for the financing of small and medium-sized enterprises. We discuss the effects of ICT on the banking sector as a whole and then apply these developments to the case of relationship banking.
The fourth chapter is an empirical study of the effects of technology on the banking business, using a sample of data from the Spanish banking industry. The design of the study is based on some of the events described in the previous chapters, and also draws from the economic literature on banking. The study shows that developments in information management have differential effects on wholesale and retail banking activities.
Finally, the last chapter is a technology assessment study on electronic payments systems in Spain and the European Union. It contains an analysis of existing payment systems and ongoing or planned initiatives in Spain. It forms part of a broader project comprising a series of country-specific analyses covering ten European countries. The main issues raised across the countries serve as the starting point to discuss implications of the development of electronic money for regulation and policies, and in particular, for monetary-policy making.

Full textAbstract:
Cette recherche a pour objectif de décrire et de comprendre le processus d'intégration des technologies Internet pour la banque à distance. Dans la mouvance de la théorie de la structuration, cette thèse propose une relecture du phénomène d'innovation associé à l'intégration des technologies de l'information. Articulant les deux niveaux de l'action et du structurel au sens de Giddens, elle vise ainsi à montrer comment ce phénomène organisationnel émerge des interactions, trop souvent considérées jusqu'ici comme opérant dans une boîte noireThe aim of this research is to describe and understand the integration process of Internet banking technologies within an organization of a large bank. In the stream of structuration theory, this thesis suggests to re-visit the innovation process associated with the integration of information technologies. Combining both levels of action and structure in Giddens' sense, this work aims at showing how this organizational phenomena emerges from social interactions between individuals. So far in the literature, these interactions have been too often considered as taking place in a black box. The theoretical contribution of this work stems from a cross fertilisation between Institutionalism, which has been broadly criticised for neglecting human interactions, and recent structurationist work on the articulation between information technologies and organisation. The latter has been criticised for The aim of this research is to describe and understand the integration process of Internet banking missing institutional embedness in the inter-organizational relationsFrom a methodological point of view, this thesis sketches a new way to translate the theory of structuration into organizations. A methodological construct has been designed accordingly to conduct a longitudinal case study in a large bank faced with the up-coming of Internet technologies. Composed of a protocol in five stages, it allows to restore take into account and combine three analytical levels: (i) the inter-organizational field which is analysed through the operationalisation of the concept of representation; (ii) the intra-organizational context which is considered as a local context (i. E. Situated in time and space); and (iii) the human interactions which are approached through the concept of episode proposed by Giddens. Finally, this research graps an important organizational phenomena related to the integration of information technologies, namely inertia. Inertia is cognitively associated with representations and organizationally entrenched in daily actions. Despite some transformations in the intra-organizational context, the study points out to unintended effects and unacknowledged conditions of managers' action that lead to inertia

Full textAbstract:
Les progrès des technologies de communication à faible consommation d’énergie et à faible cout ont révolutionne les applications de télédétection et de surveillance. L’Internet des objets (IoT) a promis la création d’un écosystème d’appareils connectes à travers un large éventail d’applications, telles que les villes intelligentes. A l’heure actuelle, de nombreuses normes et technologies concurrentes tentent de saisir l’IoT, en particulier dans le domaine des technologies de télédétection et de communication. LoRa (Long Range) est l’une de ces technologies qui gagne en popularité et en attraction dans les réseaux de capteurs sans fil (WSN). La possibilité d’établir des communications longue distance avec des nœuds relativement simples, une infrastructure minimale, des besoins en énergie réduits et l’utilisation de bandes ISM sans licence offre un avantage concurrentiel significatif. Bien que la portée de communication dans LoRa puisse dépasser 15 kilomètres en visibilité directe, le débit binaire maximal pouvant être atteint est limite à quelques kilobits par seconde. De plus, lorsqu’une collision se produit dans LoRa, le débit est encore réduit en raison de pertes de trames et de retransmissions. Les travaux de cette thèse traitent le problème des collisions dans LoRa qui peuvent survenir sous une charge importante et qui dégradent les performances du réseau.Premièrement, nous considérons le contexte des communications en liaison montante dans LoRaWAN. Nous étudions le contexte des signaux LoRa en collision synchronisée, ou chaque appareil terminal doit retransmettre toute sa trame en collision après qu’une collision se produit dans LoRa. Ce comportement diminue le débit global et augmente la consommation d’énergie des terminaux et le délai des trames. Pour cette raison, afin d’atténuer les effets néfastes des collisions, nous avons proposé un algorithme de décodage pour résoudre les signaux LoRa en collision synchronisée, dans un trafic réseau sature et confirme. Nous avons remplacé le modèle de retransmission conventionnel de LoRa en un modèle faisant en sorte que les dispositifs terminaux transmettent des bitmaps au lieu de retransmettre des trames entières pour déterminer les symboles corrects de chaque trame en collision. Notre algorithme a pu améliorer significativement le débit global de la couche LoRaWAN MAC à base de LoRa, et diminuer la consommation d’énergie des émetteurs et le délai des trames.Deuxièmement, nous considérons le contexte des communications en liaison descendante dans LoRaWAN. Nous avons remarqué que la liaison descendante dans LoRa est un goulot d’étranglements. Nous avons donc travaillé sur la sélection de la passerelle par le serveur de réseau et son impact sur le débit, la consommation d’énergie et le délai. Nous avons étudié trois types de déploiement de passerelle et nous avons montre que les performances du système dépendent de ce déploiement. Nous avons montré que l’équilibrage du nombre de terminaux par passerelle (également connu sous le nom de charge) améliore le débit par rapport au choix de la passerelle avec la meilleure qualité de signal. En outre, nous avons montré que la combinaison de la charge et de la qualité du signal n’améliore pas davantage le débit. De plus, nous avons montré que le choix de la passerelle avec la meilleure qualité de signal diminue le délai des trames et la consommation d’énergie des terminaux par rapport au choix de la passerelle avec la charge la plus faibleThe progress in low-energy, low-cost communication technologies have revolutionized remote sensing and monitoring applications. Internet of Things (IoT) has promised an ecosystem of connected devices across a wide range of applications such as in smart cities.Currently, many competing standards and technologies are attempting to seize the IoT, particularly in the area of remote sensing and communication technologies. LoRa (Long Range) is one of those technologies that is gaining popularity and attraction in the Wireless Sensor Networks (WSN) applications. The ability to make long-distance communications with relatively simple nodes, minimal infrastructure, reduced power requirements, and the use of unlicensed ISM bands provides a significant competitive advantage. Although the communication range in LoRa can exceed 15 kilometers in line of sight, the maximum bit rate that can be achieved is limited to few kilobits per second. Additionally, when a collision occurs in LoRa, the throughput is further reduced due to frame losses and retransmissions. The work of this thesis deals with the problem of collisions in LoRa that may occur under heavy load, and which degrade the performance of the network.First, we consider the context for LoRaWAN uplink communications. We study the context of fully synchronized colliding LoRa signals, where each end-device has to retransmit its entire colliding frame after a collision occurs in LoRa. This behavior decreases the overall throughput, and increases the energy consumption of the end-devices, and the delay of the frames. Therefore, in order to mitigate the damaging effects of collisions, we proposed a decoding algorithm to resolve synchronized colliding LoRa signals, in a saturated and confirmed network traffic. We substituted the conventional retransmission model of LoRa by having end-devices transmitting bitmaps instead of retransmitting whole frames to determine the correct symbols of each colliding frame. Our algorithm was able to significantly improve the overall throughput of the LoRaWAN MAC layer based on LoRa, and to decrease the energy consumption of the transmitters and the delay of the frames.Second, we consider the context for LoRaWAN downlink communications. We noticed that the downlink in LoRa is a bottleneck. Hence, we worked on the gateway selection by the network server and its impact on the throughput, the energy consumption and the delay. We studied three types of gateway deployment and we show that the system performance depends on this deployment. We showed that balancing the number of end-devices per gateway (also known as load) improves the throughput compared to choosing the gateway with the highest signal quality. Moreover, we showed that combining load and signal quality does not further improve the throughput. In addition, we showed that choosing the gateway with the highest signal quality decreases the delay and energy consumption compared to choosing the gateway with the lowest load

Devant ce constat, l’auteur formule sa thèse : la demande du marché professionnel se développera si les entreprises peuvent améliorer leur productivité grâce à l’Internet mobile. Quatre questions se posent : (1) Comment peut la firme évaluer les technologies disponibles ? (2) Quels sont les déterminants essentiels pour son usage professionnels? (3) Y a-t-il une méthodologie pour la mise en œuvre de l’Internet mobile ? (4) Est-ce que des références existent qui montrent les bénéfices de l’Internet mobile en entreprise ? Cette thèse cherche à y répondre par une observation de la pratique d’entrepriseThe mobile Internet could be a new technology helping the firm to improve productivity. But mobile Internet technology, now being widely deployed, still lacks broad usage. The author’s thesis: firms will use mobile Internet technology only if it improves their productivity. His argument reveals four questions: (1) How can the firm evaluate mobile Internet technology? (2) What determines the use in the perspective of the firm? (3) Do standards of implementation exist? (4) Are there business cases of mobile Internet technology use in the firm? These questions are being answered by a thorough observation of the firm’s practice

Full textAbstract:
L'objet de cette thèse porte sur "L'information, les nouvelles technologies d'information et l'usage d'Internet dans les entreprises d'Abidjan ". En effet, depuis 1996, grâce au programme américain dit "noeud Leland ", la Côte d'Ivoire a fait son entrée dans "l'immense pays du cyberespace ", c'est-à-dire qu'elle est désormais connectée au réseau mondial Internet. Les atouts dont il est affublé à savoir : présenté d'une part comme un facteur indéniable d'accroissement de productivité, et d'autre part comme une locomotive pour le développement économique en général, ont déterminé nombre d'organisations de Côte d'Ivoire à s'y intéresser. Les entreprises d'Abidjan qui semblent y trouver particulièrement leurs comptes ne veulent pas rester en marge du mouvement général autour des nouvelles technologies d'information. Et c'est même l'intérêt qu'elles portent à cet outil qui a inspiré l'objectif de cette recherche : étudier les usages que les entreprises destinent à cet outil. Le choix d'Abidjan comme cadre s'explique par le fait que c'est là que sont implantées la quasi totalité des entreprises connectées à l'Internet. Mais les observations préliminaires sur notre objet a révélé la pauvreté des informations disponibles. En tout cas, les données disponibles sont rares et parcellaires. Et c'est même cette situation qui a déterminé notre méthodologie. Elle s'est appuyée sur l'empirisme pour la collecte des informations originales sur ce sujet. Il a été associé à la théorie sociologique de l'innovation et à l'approche dite orientée-usager utilisée en sciences de l'information et de la communication. 100 entreprises d'Abidjan ont été sélectionnées: elles sont soit des entreprises de production ou de services, des entreprises publiques, des entreprises privées ivoiriennes et des entreprises étrangères. La proportion de chaque catégorie dans l'échantillon est fonction de ce que nous voulions montrer principalement: les usages des entreprises d'origine ivoirienne. Les résultats de l'enquête indiquent que l'introduction de l'Internet dans les entreprises d'Abidjan n'a pour le moment pas induit de changement notable: les canaux traditionnels de communication continuent d'avoir pignon sur rue; 85% des entreprises d'Abidjan les utilisent au détriment de l'Internet. Cependant l'usage le plus répandu s'avère la messagerie électronique : 64% des entreprises pratiquent le courrier électronique, laissant les autres fonctionnalités quasiment inexploitées. Ces résultats permettent d'affirmer que ceux qui manipulent l'Internet à Abidjan sont plutôt des utilisateurs et non encore des usagers. Cet état de chose s'explique, entre autres, par la limitation de temps devant l'ordinateur qu'imposent souvent les chefs d'entreprises à leurs collaborateurs pour des raisons économiques. Quoi qu'il en soit, l'Internet prépare une certaine modernisation des entreprises connectées d'Abidjan et ouvre la voie qu'empruntera tranquillement la mondialisation.

Cette thèse a pour objectif l'étude des portails d'accès internet. Elle met en perspective les nouveaux services offerts aux utilisateurs de bibliothèques nationales et s'interroge sur certains nombres d'aspects stratégiques dont surtout : la définition des portails, le choix des dispositifs d'information et de communication, la question de la normalisation des documents numériques et leur échange, le développement des bibliothèques numériques. . . On s'est appuyé sur des applications mises en œuvre dans des grandes bibliothèques, la Bibliothèque nationale de France, la Bibliothèque nationale de Canada et la Bibliothèque du Congrès, en particulier. Notre travail se focalise également sur l'impact de la TIC sur les portails de ces bibliothèques, notamment en matière de services et de missions. Deux problématiques essentielles ont été le fil conducteur de la réflexion développée ici : En quoi les TIC implémentées dans un portail d'internet vont-elles accroître les capacités de services proposés par les bibliothèques et, par conséquent, en modifier les perspectives ? De quelle manière les portails d'accès internet optimisent-ils l'accès aux ressources, non seulement électroniques, mais encore conventionnelles ?This thesis aims at the study of the internet access portals. It puts in prospect the new services offered to the users for national libraries and wonders about certain numbers of strategic aspects of which especially the definition of the internet portals, the choice of the devices of information and communication, the question of the standardization of the numerical documents and their exchange, the development of the digital libraries. We were based on applications implemented in large libraries, the national Library of France, the national Library of Canada and the Library of the Congress, in particularOur work is also focused on the impact of the TIC on the internet portals of these libraries, in particular services and missions. Two essential problems were the discussion thread of the reflexion developed hereIn what the TIC implemented in a Internet portals will they will increase the capacities of services suggested by the libraries and, consequently, modify the prospects for them? How do the internet access portals optimise the access to the resources, not only electronic, but still conventional?

Full textAbstract:
This dissertation attempts to expand our understanding of the deficient self-regulation (DSR) of Internet use and media habit development. Drawing from a social cognitive perspective, DSR is described as lapses in effective self-control that are self-corrected over time. A shortcoming in this area of research is that factors relevant to the technology that may encourage the development of DSR or media habits are rarely, if ever, discussed. A large focus of existing research is instead narrowly placed on individual factors that motivate DSR and media habits. An extension is proposed to theory on DSR in this dissertation by examining the role played by novelty perceptions of technology. In the initial stages of technology use, when perceptions of novelty generally grow, perceived novelty is hypothesized to elicit a state of flow, which in turn diminishes the subfunctions of self-regulation and provokes DSR. The relationship between perceived novelty and flow is moderated by psychosocial problems, boredom proneness, and self-reactive outcome expectation. As perceived novelty of a technology decreases, it is presumed that self-control is restored given that flow no longer inhibits self-regulation. However, DSR and media habits are hypothesized to persist in later technology use if individuals experience psychosocial problems, boredom proneness, or high self-reactive outcome expectations. The manifestation of DSR in later stages of technology use increases the likelihood of forming media habits. The influence of novelty perceptions was evaluated on flow, DSR, and media habits at initial and later stages of technology use. The pretest demonstrated that a novelty frame successfully manipulated novelty perceptions of Second Life, the technology used in this experiment, in anticipated directions. In the main study, perceived novelty resulted in flow, which in turn predicted growth of DSR during initial stages of Second Life use. In the familiar stages of use, DSR led to the development of media habits over time; however, the relationship between novelty perceptions and DSR was not moderated by psychosocial problems, boredom proneness, or self-reactive outcome expectation. The findings of this investigation are discussed aside their implications for research, theory, and practice.

Full textAbstract:
Influencé par le discours de la science qui entretient l’illusion que « tout est possible » et efface toute trace de négativité, le sujet postmoderne a perdu le sens des limites et de la castration symbolique. Dans notre société individualiste où tout doit aller encore plus vite, encore plus loin, l’ « individu incertain » se retrouve seul face à ses responsabilités. En « panne de l’Autre », en quête de sens et de repères, il laisse apparaître des signes de fragilité. C’est ainsi que sont nées de nouvelles formes d’expression de la souffrance et de nouvelles pathologies telles que la cyberdépendance et la dépression contemporaine. Ce travail d’inspiration psychanalytique tente de montrer qu’Internet est un révélateur du sujet post-moderne et notamment en termes de dépression. A travers quelques cas cliniques, l’auteur tente d’expliquer la fascination de l’internaute pour les sites de psychologie et leurs babillards électroniques. A la lumière de l’approche psychanalytique, ce travail analyse la souffrance des participants comme un symptôme du malaise social. Cette dépression contemporaine appelle des réponses contemporaines mais ce lieu virtuel de communication qui évacue la place du sujet, déni le réel et accorde une place prépondérante à l’imaginaire, est-il une de ces réponses ? Ce travail propose de réfléchir aux modalités d’une clinique du virtuelInfluenced by the speech of the science which maintains illusion that “all is possible” and erases any trace of negativity, the postmodern subject lost direction of limits and castration symbolic. In our individualistic society where all must go even faster, even further, the “dubious individual” finds himself only vis-a-vis his responsibilities. In “breakdown of the Other”, in search of direction and reference mark, it lets appear signs of brittleness. Thus were born from new forms of expression of the suffering and new pathologies such as the cyberdépendance and the contemporary depression. This work of psychoanalytical inspiration tries to show that Internet is revealing post-modern subject and in particular in terms of depression. Through some clinical cases, the author tries to explain the fascination of the Net surfer for the sites of psychology and theirs babillards electronic. In the light of the psychoanalytical approach, this work analyzes the suffering of the participants like a social symptom of faintness. This contemporary depression calls contemporary answers but is this virtual place of communication which evacuates the place of the subject, refusal reality and grants a dominating place to the imaginary one, one of these answers? This work proposes to reflect on the methods of a virtual clinic

Full textAbstract:
L'objectif de cette thèse est d'étudier l'impact des technologies de l'information et de la communication (TIC) sur les coûts de transaction. Elle comporte cinq chapitres. Le premier est consacré essentiellement au développement de la « nouvelle économie », lié à la démocratisation de l'usage des TIC. Or, ces TIC affectent aussi l'environnement informationnel des agents et la nature de leur rationalité, déterminants essentiels des coûts de transaction. Le second chapitre rappelle donc les raisons de l'existence de la théorie des coûts de transaction, ainsi que ses principaux concepts et hypothèses. Quant au troisième chapitre, il démontre comment les TIC réduisent ces coûts de transaction. Ces derniers sont décomposés en coûts de coordination et coûts de motivation. On démontre que les TIC réduisent les coûts de coordination en améliorant l'efficience économique située au niveau de l'amélioration des processus commerciaux et des bénéfices du commerce électronique. Quant à l'impact des TIC sur les coûts de motivation, on discute de la problématique de l'asymétrie d'information. Nos conclusions suggèrent que la baisse des coûts de coordination est importante. Cependant, l'Internet n'est pas marqué par plus d'asymétrie d'information que le marché traditionnel. Le quatrième chapitre s'intéresse au choix organisationnel en rapport avec l'effet des TIC sur les coûts de transaction. Les limites du choix marché/hiérarchie débouchent sur l'apparition des théories qui tiennent compte de la cœxistence de ces deux choix organisationnels dans de nouvelles formes d'organisation telles que les réseaux. Les principales caractéristiques de ces formes organisationnelles font l'objet des développements du dernier chapitreThe aim of this thesis is to study the impact of information and communication technologies (ICT) on the transaction costs. It is composed of five chapters. The first treated principally the development of « new economy », linked to the democratization of the usage of ICT. These ICT affect also the informational environment of the agents and the nature of their rationality, essential determiners of the transaction costs. The second chapter reminds therefore the reasons of the existence of the theory of transaction costs, as well as its main concepts and hypotheses. The third chapter shows how ICT reduce these transaction costs. We distinguish the impact of ICT on coordination costs and on motivation costs. We demonstrate that ICT reduces coordination costs and increases efficiency. These efficiencies are process improvement of trade and marketplace benefits. At the same time ICT affect motivation costs, we discuss the effect of Internet on informational asymmetries. Our conclusions suggest that reduction of coordination costs is important. However, the Internet is not marked by more asymmetry of information than the traditional market. The fourth chapter is interested in the organizational choice related with the effect of ICT on the transaction costs. The limits of the choice market/hierarchy result in the appearance of the theories which take into account the coexistence of these two organizational choices in new forms of organization such as networks. The main characteristics of these organizational forms make the object of the developments of the last chapter

Full textAbstract:
L’apparition des réseaux numériques dans le milieu professionnel continuent de susciter des interrogations au regard du fonctionnement des entreprises de presse. La production et la diffusion de l’information ne sont plus l’apanage des seuls journalistes qui paraissent éprouvés par les mutations technologiques. Leur identité professionnelle est mise à rude épreuve et selon les contextes socio-économiques, ils tentent d’apporter des solutions à la mondialisation de l’information. Le Sénégal n’échappe pas à ce processus de l’information numérique avec l’émergence des journaux en ligne. Ceux-ci tentent de s’adapter à la publication en ligne en se fondant sur l’univers socio-économique sénégalais et les exigences du monde moderne. Les discours sur les technologies de l’information et de la communication (Tic) sont l’objet de conjectures partagées entre un optimisme perpétuant l’idéologie du modèle libéral capitaliste et un pessimisme mettant l’accent sur les aspects socioculturels. La compréhension et la signification des actions sociales sont les principales motivations de cette thèse. Celle-ci a pour objectif d’analyser les discours et représentations de cette presse en ligne sénégalaise dans une approche socio-dircursive. À partir de la sociologie compréhensive wéberienne, la presse en ligne sénégalaise au prisme de l’économie et de la politique sera étudiée, afin de révéler les expériences locales témoignant des pratiques culturelles à l’œuvre. À travers la vie quotidienne des acteurs sociaux nous tenterons d’éclairer les notions d’usage et d’appropriation. Les logiques sociales existantes observées par le biais d’indicateurs de comportements des acteurs vont déterminer les spécificités de cette presse en ligne sénégalaiseThe emergence of digital networks within professional environment continues to provoke some questions with regards to the functioning of press corporations. Journalists, who meet with technological changes, are not the only ones whose prerogatives are the production and broadcasting of the media. Their professional identity is put to the test when applied to the context of the social and economic environments, thus they are seeking solutions to the globalization of the media. Senegal is no exception to this process of digital media with the coming out of the on-line newspapers which try to adapt to the on-line publication and therefore are based on the social and economic environment of Senegal and the demands of the modern world. Discussions about information and communication technologies are subject to divided opinions, particulary between the optimistic view which perpetuates the ideology of the liberal capitalistic system and the pessimistic view emphasizing social and cultural aspects. The understanding and meanings of social actions are the main objectives of this thesis, the aim of which is to analyse the representations and theories of the Senegalese on-line press within a socio-discursive scope. Based on this comprehensive Weberian sociology, the on-line press in Senegal will be studied through economics and politics in order to reveal the local cultural experiments at work. Through the everyday life of social actors we will try to emphasize their appropriation and use of the media. The existing social logics observed by means of indicators of these actors’ behaviours will determine the specificities of the Senegalese on-line press

Deux objectifs fondamentaux sont attachés à notre problématique de recherche. Le premier consiste à repérer et à décrire les pratiques d'usage de l'Internet par les experts-comptables, dirigeants de PMCEC, dans le cadre de leur environnement professionnel afin d'infirmer ou de confirmer l'hypothèse d'un possible « déterminisme technologique ». Le second consiste à identifier les éléments explicatifs des pratiques déjà observées. L'étude de terrain réalisée auprès de 283 experts-comptables révèle que : Loin d'être un groupe homogène, il se trouve que les experts-comptables s'approprient Internet de manière différenciée. L'analyse typologique a fait émerger trois profils d'experts-comptables aux usages bien distincts de l'Internet: les « spécialistes », les « pragmatiques » et les « suiveurs ». Il n'existe pas de véritable déterminisme individuel ou organisationnel qui explique la variabilité dans les pratiques observées mais des tendances intermédiaires entre certains indices de déterminisme individuel et de déterminisme organisationnelTwo fundamental objectives are behind our research. The first one is to discover and describe the Internet usage by Chartered Accountants, managers of SMAFs in their professional environment, in order to reject or to confirm the assumption of possible “technological determination”. The second objective is to identify the explanatory factors which may affect the observed practices. The empirical survey conducted into 283 Chartered Accountants reveals that: Far from being an homogeneous group, we found that Chartered Accountants appropriate Internet differently. A cluster analysis has been applied and three profiles of Chartered Accountants have emerged based on their Internet use: “the specialists”, “the pragmatics” and “the followers”. There is no single factor, whether individual or organisational which explain the wide variety of the observed practices, there are however some intermediary tendencies involving both individual & organisational determinants

Full textAbstract:
Avec la Convention pour la Sauvegarde du Patrimoine Culturel Immatériel de l’UNESCO (2003), le concept de patrimoine s’est trouvé élargi à de nouveaux objets, mais surtout une nouvelle distribution des rôles s’est opérée parmi les acteurs, mettant les praticiens individuels et collectifs au coeur du dispositif. Les états qui ont ratifié la convention se sont donné l’obligation de procéder à des inventaires en impliquant les communautés dans la désignation de ce qui, pour elles, fait patrimoine immatériel, offrant ainsi une opportunité d’expérimentations de formes et de méthodes pour réaliser cet objectif. Ces inventaires se sont largement appuyés sur des technologies numériques pour leur constitution et sur le web pour leur diffusion. La dynamique sociale dans laquelle s’inscrit la notion d’inventaire s’appuie sur un imaginaire des techniques numériques comme moyen de conjurer la perte culturelle et une relation ambigüe se noue au moment de l’inventaire nativement numérique entre immatériel et virtuel. L’étude du récit de l’histoire du web permet de mettre en évidence un ensemble de mythes fondateurs d’Internet qui contribuent à cette ambiguïté. À partir d’une participation observante à l’Inventaire du Patrimoine Immatériel Religieux du Québec (IPIR), qui s’appuie sur les définitions de la convention UNESCO, il s’agit de considérer les technologies numériques, dont Internet, comme outils que les communautés (État, communautés locales, acteurs de l’inventaire) mobilisent pour se mettre en scène par le patrimoine immatériel. L’exemple de l’IPIR, chargé de trois missions (conserver la mémoire, répertorier les pratiques vivantes, les communiquer), comparé à d’autres inventaires en ligne existants illustre la plasticité des inventaire du Patrimoine Culturel Immatériel. Les trajectoires de l’inventorisation émergent en interrogeant la demande sociale d’un inventaire du Patrimoine Culturel Immatériel religieux dans le contexte de déchristianisation du Québec à partir des années 1960. Enfin, la diffusion sur le web des données d’inventaire permet de questionner les usages des techniques et les formes de représentations du web comme moyen de transmission culturelle. Alors que la dynamique sociale dans laquelle s’inscrit un inventaire en ligne s’appuie sur un imaginaire des techniques numériques comme moyen de conjurer la perte culturelle, la prolifération des traces sur le web vient défier la promesse d’accessibilité universelle que portait le web des originesWith the Convention for the Safeguarding of the Intangible Cultural Heritage of UNESCO (2003), the concept of heritage was expanded to new objects, but above all a new distribution of roles was made among the actors, putting the practitioners individual and collective at the heart of the device. States that have ratified the convention have given themselves the obligation to carry out inventories by involving the communities in the designation of what, for them, constitutes intangible heritage, thus offering an opportunity for experimentation of forms and methods to achieve this goal. These inventories were largely based on digital technologies for their constitution and on the web for their dissemination. The social dynamics in which the notion of inventory is inscribed is based on an imaginary of digital techniques as a means of warding off cultural loss, and an ambiguous relationship is formed at the time of the natively digital inventory between immaterial and virtual. The study of the narative of the history of the web makes it possible to highlight a set of founding myths of the Internet which contribute to this ambiguity. Based on an observant participation in the Inventory of the Intangible Religious Heritage of Quebec (IPIR), which is based on the definitions of the UNESCO Convention, digital technologies, including the Internet, should be considered as tools that the communities (state, local communities, actors of the inventory) mobilize to be staged by intangible heritage. The example of the IPIR, with three missions (keep the memory, list the living practices, communicate them), compared to other existing online inventories illustrates the plasticity of the intangible cultural heritage inventory. The trajectories of inventorization emerge by questioning the social demand for an inventory of intangible cultural heritage in the context of de-Christianization of Quebec from the 1960s. Finally, the web-based dissemination of inventory data makes it possible to question the uses of techniques and forms of representation of the web as a means of cultural transmission. While the social dynamics in which an online inventory is based on an imaginary digital techniques as a means to avert cultural loss, the proliferation of tracks on the Internet comes to challenge the promise of universal accessibility that the web was wearing. origins

Full textAbstract:
New information and communication technologies have excited considerable
popular and expert attention over the last decades of the twentieth century.
Predictions about their social effects range along a continuum from visions of
heaven; where people slip the surly bonds of time and space, to glimpses of hell;
where such slippage enables new manifestations of dominance and control. Along
the continuum there is a basic determinist premise evident, that the technologies
have developed in a marginal sphere, and will now bring a new way of life, or at
least provide materials for a new way of life, whether this be for good or evil. The
notion of cyberspace as a new communicative domain has in particular engaged
this kind of attention.
This thesis is concerned with the ways in which the rhetoric of cyberspace sheds
light on deeper social preoccupations and relations. It is an attempt to move
beyond discussion of particular technologies and their possible effects to examine
the ways in which habitual social intercourse is reconstructed in and around
cyberspace. As a feminist scholar of communication I am particularly interested
in the ways in which existing gender relations are maintained in discursive
constructions of women in cyberspace, and the ways in which feminist theorists
may respond to the new domain.
Because I seek to elude simple determinism, I have sought to contextualise the
space by some focus on the known social needs, purposes and practices to which
the development of cyberspace technologies has been central. Although I
acknowledge the power of discourse to maintain extant social relations, I seek to
elude discursive determinism by some focus on the ways in which women have
creatively appropriated new technologies; on the disjunctions of discourse and
practice.

>Magister Scientiae - MScThe growing size of raw data and the lack of internet communication technology to keep up with that growth is introducing unique challenges to academic researchers. This is especially true for those residing in rural areas or countries with sub-par telecommunication infrastructure. In this project I investigate the usefulness of cloud computing technology, data analysis workflow languages and portable computation for institutions that generate data. I introduce the concept of a software solution that could be used to simplify the way that researchers execute their analysis on data sets at remote sources, rather than having to move the data. The scope of this project involved conceptualising and designing a software system to simplify the use of a cloud environment as well as implementing a working prototype of said software for the OpenStack cloud computing platform. I conclude that it is possible to improve the performance of research pipelines by removing the need for researchers to have operating system or cloud computing knowledge and that utilising technologies such as this can ease the burden of moving data.

Full textAbstract:
La thèse porte sur un sujet qui suscite bien des questionnements tant les entreprises liées aux technologies de l'information et de la communication ont pris de l'importance dans nos sociétés contemporaines. L'analyse repose essentiellement sur la mesure du processus de la création des établissements économiques relevant du secteur des TIC, de leur succès et de leur taux de survie. Toute discussion sur la nécessité d'une politique " régionale " de soutien adaptée aux spécificités de l'espace économique des différentes collectivités territoriales reste théorique sans une connaissance des disparités spatiales de la création d'entreprise et des facteurs ou déterminants qui en sont à l'origine. L'analyse conduit à valoriser l'espace géographique comme variable déterminante et discriminante tout en prenant appui sur les critères sectoriels pour évaluer les effets régionaux liés aux entreprises elles-même, à leur spécialisation et à leur capacité à entraîner un développement induit. Mais, l'interrogation porte aussi sur les déterminants socio-économiques dépendant de l'entreprise et sur les déterminants " individuels " liés au créateur. La recherche des déterminants met en avant trois groupes de facteurs explicatifs : les " savoirs du créateur ", les caractéristiques des entreprises au démarrage et la richesse des externalités. Les résultats de notre étude mettent en avant que les actions d'aide à la création risquent de rester inefficaces et peu ciblées sans une connaissance approfondie de la spécialisation sectorielle régionale, des tendances actuelles, des disparités spatiales, mais aussi les facteurs déterminants de la création et ceux de la survie et du succès des jeunes entreprises. L'analyse de la filière TIC montre également que les jeunes entreprises de cette branche ne doivent pas seulement être évaluées, mais aussi aidées plus spécifiquement que les entreprises " traditionnelles ". L'aide à la création, pour être efficace, devrait plus amplement considérer les différences entre les filières principales retenues. La question est alors de prendre conscience de la spécificité du champ des TIC et de la diversité des situations pour mettre en œuvre des politiques d'aide et de soutien qui fonderaient leur efficacité dans la nuanceThe present doctoral thesis is responding to the key role that new firms in information and communication technologies (ICT) keep in our contemporary society and their importance for the regional economies. The analysis focuses on the measuring of the firm birth rates in the 348 working areas in France and the key factors that determine the survival and the success of the young firms. Designing the regional policies is vain without a deeper knowledge of the regional firm birth process in its different aspects. The analysis of the economic environment identifies a number of key variables influencing positively the regional ICT firm birth rates: precedent population growth, presence of big firms, number of ICT-firms (proximity effects, informal information flow) and the role of the regional R&D-infrastructure. Proximity effects, economies of localization confirm the important role of formal and informal regional networks (“milieu”). Secondly, the socio-economic factors (structure of the firm and human capital of the founder) and their importance for the success of the new firms was analyzed. Three explanatory main fields were identified: knowledge and competence of the founder, structure of the firm at the beginning of its activities and the positive externalities of the local working area. The key result of the study is that without a deeper knowledge both of the determinants of ICT-firm birth rates and both of the key factors of the success of the new firms, the aid and promotion risk to be less efficient. The structural analysis of the ICT sector shows also that the new firms of this branch need to be evaluated and aided separately and in a very specific and adapted manner, different to non innovative, “traditional”, enterprises. Moreover, the aid of the creation, to be efficient, has to consider more intensely the differences between the principal branches inside the ICT sector. The question is to take conscience of the specificity and complexity of the of the ICT sector for an improved design of policies, strategies and infrastructure, considering the diversity of situations in the firm birth process and the development of the ICT firms

Full textAbstract:
Si d’importantes recherches sur les sources du droit et de nombreux travaux sur le droit de la communication par internet ont déjà été menés, cette thèse se distingue des premiers comme des seconds : d’une part, elle interroge des sources souvent originales, loin de réduire le droit à la loi et à la jurisprudence ; d’autre part, elle ne consiste pas en un exposé technique et utilitaire du droit de la communication par internet mais en une étude scientifique et macro-juridique (i.e. détachée des règles et des régimes juridiques). L’observation du droit de la communication par internet est ici au service d’une réflexion relative aux continuités, aux ruptures et aux mouvements actuels et à venir des sources du droit. Cette branche du droit, significative du droit « global » et du droit « postmoderne », est révélatrice de ce à quoi le paysage juridique pourrait ressembler demain, lorsque le droit moderne stato-centré aura été irrémédiablement débordé par un droit « en réseau » dont les propriétés ressemblent fort à celles du réseau mondial qu’est l’internet. Progressivement, les sources auparavant premières deviennent secondaires, celles qui hier demeuraient à l’arrière-plan se retrouvent sur le devant de la scène juridique, tandis que de nouveaux foyers de normes apparaissent. L’objet de cette thèse est de constituer un témoignage de ce renouvellement des lieux et des modes de production des normes en coursMany books studying the sources of the law and many books studying the Internet law have already been published. This thesis differs from these books : it studies the original sources, not only the state law and the customs; and it is a scientific work and not a practical work. Observations of the Internet law can serve thoughts on the currents and futures continuities and changes of the sources of the law. Studying this young and special law is like studying an example of global law and postmodern law, revealing the specifics of the law of tomorrow, when the modern law centered on the state will be replaced by a different law, whose properties gather those of the Internet. Gradually, the conventional sources are substituted by new sources. This thesis wants to be a witness of these changes in the sources of the law.In terms of legal science and legal thought, lawyers should perhaps avoid analyzing the law of tomorrow with tools and lessons from yesterday. Studying the Internet law invites to build new tools and frameworks in order to describe and explain as accurately as possible the reality of the law. These problems led to the writing of this book. By focusing on specific legal objects that reflect the twenty-first century law, it wants to promote the understanding and the acceptance of changes in the law. Specifically, the objective is to contribute to the renovation of the sources of the law thought when the modern theory appears increasingly archaic because the number, the identity, the architecture and the balance of the sources is permanently evolving

Dans cette recherche, nous nous intéressons à la question du non-usage de la technique. Nous nous attachons dans un premier temps à l’étude de certaines techniques d’information et de communication qui se sont trouvées confrontées à différentes formes de refus à travers l’histoire. A partir d’une étude de terrain, nous analysons dans un deuxième temps le refus de l’usage d’Internet. Dans cet univers technologique, il n’y a pas que des usagers mais aussi des non-usagers, des réfractaires qui refusent cet outil : refuser dans le sens de rejeter, ne pas y consentir, ne pas accepter de l’adopter et de l’utiliser. Nous voulons à travers ce travail comprendre les raisons de ce refus. Ce phénomène ne doit pas être considéré comme un disfonctionnement mais comme un fait qui doit être expliqué et qui peut avoir des raisons respectables. Le refus semble viscéral et irrationnel, simplement parce que la nouveauté technique fait peur. Mais il procède aussi d’une réflexion, d’une analyse, d’un ensemble d’opinions et d’idées réfléchies. En définitive, le refus de l’Internet s’avère recouvrir une multitude de paramètres. Plusieurs éléments explicatifs d’ordre technique, psychologique, cognitif, culturel et idéologique ont été identifiés lors de notre enquêteIn this research, we are interested in the issue of the non-usage of technology. As a first step, we investe in the study of the different forms of refusal that certain information and communication techniques were confronted with across history. As a second step, and on basis of a field study, we analyse the reasons of Internet usage refusal. In this technological world, there are not only users but also non-users, recalcitrants who refuse this tool: refuse in the sense to reject, not agree to it, not agree to adopt it and to use it. We want throughout this job to understand the reasons for such refusal. This phenomenon should not be considered to be a dysfunction but a fact that must be explained and that can have respectable reasons. The refusal seems visceral and irrational, merely because the technical novelty frightens. But it also proceeds from a reflection, an analysis, a set of opinions and thoughtful ideas. Definitely, the refusal of the Internet seems to cover a multitude of parameters. Several explicative elements of technical, psychological, cognitive, cultural and ideological order were identified during our inquiry

L'étude du déploiement des infrastructures Internet permet de caractériser l'insertion d'un espace dans la mondialisation. En Afrique de l'Ouest, le développement territorial du réseau témoigne d'un réel dynamisme, d'origine déjà ancienne, qui permet à certains espaces ouest africains d'être reliés aux flux mondiaux d'information. Ce maillage est cependant lacunaire, avec des différences significatives entre les pays mais également au sein des territoires nationaux. Un développement plus important du réseau en Afrique de l'Ouest se heurte à des contraintes multiples (géographiques, techniques, politiques et économiques) qui se manifestent à plusieurs échelles. Dans ces conditions, la place limitée des pays ouest africains dans la gouvernance du système technique d'Internet devient un obstacle majeur au développement du réseau au sein de ces territoires, tout comme à leur plus grande intégration dans le système mondeThe study of the development of Internet infrastructure makes it possible to define the incorporation of a territory within the globalization process. In West Africa, the territorial development of this network shows a real dynamism, already in existence, which allows some West African places to be connected to the worldwide information flow. There is however some missing links to the grid, with significant differences between the countries, but also within the national territories themselves. The development of the network in West Africa now encounters multiple constraints (geographical, technical, political and economic) in several scales. Consequently, the limited place occupied by the West African countries in the governance of the technical system of the Internet, therefore becomes a major obstacle to both the development of the network itself within these territories as well as to their enhaced integration into the global system

Full textAbstract:
This thesis aims to examine how patient empowerment based on Internet information has impact on health care processes and patient &ndashphysician relationship. The process of empowerment is analyzed in three main steps
searching and obtaining information
sharing and discussing obtained information with providers
and involving decision making process. Study domain covers with breast cancer patients continuing their treatment in hospitals. In-depth interview methodology has been employed. Interviews are conducted in two settings: one is a university hospital
other is a state hospital of Ministry of Health. Sample size was 20 patients and 6 doctors. As result of study we observed that most of the breast cancer patients have low level of empowerment. This is mainly caused by perception of cancer and high level of anxiety of patients. Most of the middle class women even though they use Internet in everyday life, they neither want to search for information on their cancer not they want to involve in decision making.. Some of the educated upper middle class use Internet however they do not share gathered information with their doctors. They mainly use this information to test competency of doctor. Most patients prefer to seek for information until they made a decision, mostly finding a trustable doctor. Even though some of upper middle class, high education women use Internet intensively, they do not involve in decision and leave the responsibility to the doctor. Young generation regardless of their socio economic situation has tendency to use internet and getting empowered.

Full textAbstract:
L’avènement des TIC accentue le phénomène des communautés virtuelles. Privilégiant plutôt l’aspect social que technologique, l’objectif de cette thèse est de comprendre la communication et l’organisation dans ces communautés. Le problème terrain a été d’étudier ce phénomène dans un contexte communautaire. Les investigations se sont alors focalisées sur l’analyse d’un site sportif d’e-commerce primé par de nombreux prix d’innovation en terme de modèle de constitution communautaire: Sportmalin. Com Dès lors sur le plan théorique, nous envisageons les TIC comme « des artéfacts communicationnels ». Le principal intérêt est de révéler que le phénomène communautaire provient majoritairement d’une médiation entre trois objets antinomiques du système mais néanmoins interreliés : les outils communautaires, les enjeux mercantiles et la volonté des membres de faire partager leurs connaissances. Pendant 20 mois, l’analyse nous apprend qu’une adéquation est possible entre une problématique mercantile et communautaire. Tel un rouage, chaque partie (communautés virtuelles, outils communautaires, TIC, marketing et multinationales) se complète tout en restant dépendante les unes des autres. L’ensemble du phénomène de communauté virtuelle résulte de stratégies d’acteurs et de choix rationnels. Bien que les communautés virtuelles semblent être le produit d’efforts délibérément coordonnés d’un ensemble d’acteurs, le facteur humain constitue la variable instable de ce système communautaire. La conclusion révèle que la « communauté virtuelle commerciale », telle que nous allons la décrire au cours de cette étude, constitue le modèle universel de toute communauté virtuelle artefactThe increasing of ICT accentuates the phenomenon of the virtual communities. Rather privileging the social aspect more than the technological aspect, the aim of this thesis is to understand communication and organization in these communities. The ground problem has been to study this increasing phenomenon in a community context. The investigations then focused on the analysis of a community site of e-business in sports awarded by numerous innovation prizes as model of a community constitution: sportmalin. Com. Therefore from a theoretical point of view, it is necessary to understand the ICT as “communicational actefacts”. The principal interest was to reveal that the community phenomenon mainly results from a mediation between three antinomic objects of the system but nevertheless linked together : the community technical tools, the mercantile stakes and the will of the members to share and exchange their knowledge. The survey led during twenty months teaches us that an adequacy is possible between a mercantile and a community problematics. Just like a cog of a system, every part (virtual communities, community tools, the ICT, marketing initiative and the multinationals) completes the other as well as remaining dependent with the others. The analysis grants that the whole phenomenon of virtual community is the sole result of strategy of actors and rational choices. Although the virtual communities seem to be the product of deliberately coordinated efforts of a set of actors, the human factor is the unstable variable of this community system. The conclusion of this research reveals that the “ virtual commercial community ”, such as we are going to describe it in this study, establishes the universal model of any virtual community artefact

Full textAbstract:
Ce mémoire de thèse propose une analyse des pratiques de communication intercommunales. Notre objectif est de cerner quels enjeux renferment le recours aux Tic pour les établissements intercommunaux. En effet, l'émergence de politiques de communication intercommunales renvoie au renforcement du pouvoir intercommunal favorisé par le processus de décentralisation engagé par l'État. Conformément à ce pouvoir d'action, les communautés tentent de construire des échanges sociaux avec les individus. Elles visent la reconnaissance de leur autorité publique et l'adhésion à leur « projet territorial ». Les Tic sont associées à cet objectif de construction territoriale s'inscrivant dans un contexte de concurrence à l'échelle locale. Par le recours aux Tic, les structures intercommunales investissent la sphère publique en proposant une symbolisation de leur action. L'analyse des pratiques de communication nous permet d'aborder les Tic dans leur double dimension : d'un point de vue technique en pointant leurs caractéristiques et d'un point de communicationnel en s'intéressant aux discours produits. Nous avons pu noter que les responsables intercommunaux ont très tôt associés ces techniques à une vision déterministe par l'usage des termes «territoires numériques» ou «cyberterritoires». En lien avec cette vision déterministe, nous avons relevé une structuration de l'activité communicationnelle autour du site internet. En l'espace de quelques années, l'éventail des supports de communication intercommunaux s'est progressivement réduit au profit des sites internet. La gestion du site web dévoile une rationalisation et spécialisation dans la production des contenus communicationnels. De ce fait, notre recherche s'intéressera à l'éditorialisation des contenus dans la mesure où elle contribue à introduire une nouvelle gestion de l'information au niveau intercommunalThis PhD thesis analizes communication practices of intercommunal structures. Our aim is to identify the stakes of the use of ITC for intercommunal structures. The emergence of intercommunal communication shows the consolidation of intercommunal authority at local scale. The intercommunal consortia intend to build social interactions with individuals. They aim for the recognition of their public authority and win support in the accomplishment of their « territorial project». At local scale, the ICT are associated to the purpose of territorial building in a competitive context. By the use of ITC, intercommunal structures invest the public sphere offering a symbolisation of their action. The analyse of communication pratices allows us to study ITC in a double dimension : as technicals objects pointing out their specifications and as communication support focusing on their messages. We pointed out that intercommunal officials elected associated these techniques to a determinist vision, using the expressions « digital territories » or « cyberterritories ». In link with this vision, we can note the structuring communication on the website. In a few years, the amount of communication tools has reduced in favour of websites. The management of website reveals a rationalization and specialization in the production of communicative contents. Therefore our research will focus on editorialisation of contents in so far as it contributes to introduce a new management of information in these structures

Full textAbstract:
La diffusion aujourd'hui massive de l'informatique et la démocratisation des usages de l'Internet, de la téléphonie mobile, ou plus récemment d'autres objets communicants, génèrent une profusion de traces numériques gardant la mémoire des actions des usagers. Vanté par certains qui y voient l'opportunité d'améliorer la sécurité publique, la relation marchande ou encore leur propre confort par exemple, ce constat fait craindre à d'autres l'avènement d'une société de la surveillance érodant le sens du privé. Le présent travail s'interroge sur la notion de privacy à l'ère du numérique, et montre comment les changements technologiques, serviciels et d'usage mettent en tension l'acceptation traditionnelle de la privacy fondée sur des normes. Si les problèmes de privacy liés aux technologies de l'information et de la communication ne sont pas nés avec l'ère numérique comme le montre notre analyse socio-historique, des changements se produisent aujourd'hui qui durcissent les tensions expérimentées par les usagers, et questionnent les modalités de régulation pour y répondre. Un changement d'ampleur dans la quantité d'informations existante et dans l'accessibilité de celles-ci change la nature des risques en termes de privacy. Ceux-ci deviennent difficiles à anticiper, et ne se perçoivent bien souvent qu'au travers des problèmes de privacy, une fois ceux-ci révélés. L'analyse de micro-affaires ordinaires et de cas plus médiatisés intervenant dans différentes sphères d'usage montre que la réflexion en termes de privacy doit désormais s'orienter vers le développement de modalités de régulation complémentaires au dispositif normatif existant, modalités plus souples et appropriables par les individusThe massive diffusion of information technology and of the Internet, of the mobile phone and of other communicating technologies produce lots of digital traces which keep the memory of people's acts. Some see in these changes the opportunity to increase security, Customer relationship management or comfort in everyday life. But some other fear the advent of a surveillance society in which privacy would erode. We examine here what privacy in the digital age means, and how the technological changes, but also services and uses changes unhinge the traditional privacy acceptation based on norms. Privacy problems predate the digital era. But somme changes nowadays harden privacy problems and call into question the way these problems are responded to. The wide scope of digital information and its accessibility affects privacy risks, which become difficult to pre-empt. Crises analysis shows that privacy reflexion shall from now on go in for complementary ways that should be easygoing for people to use them

Full textAbstract:
With the ever increasing number of Internet of Things devices going out on the market for consumers that are Zigbee certified there is a need for security testing. This is to make sure that security standards are upheld and improved upon in order to make sure networks are protected from unauthorized users. Even though a lot of research and testing has been done on the Zigbee key exchange mechanism, called Zigbee commissioning, improvements have still not been enough with severe vulnerabilities in consumer grade devices still existing today. The devices tested in this study use EZ-mode commissioning in order to exchange the network key between a Zigbee coordinator and a Zigbee end device in order to encrypt later communication after being paired. By using a simple radio receiver and a packet capturing program such as Wireshark an eavesdropping attack was conducted in order to capture the network key. The experiment demonstrates that this is still a weak point as the network key was successfully captured using eavesdropping. The analysis of the results show that previous criticisms of Zigbee commissioning have still not fully been addressed and can be a potential weak point in networks that use Zigbee certified IoT products.

Full textAbstract:
Ce travail se propose de contribuer à l'analyse des effets de l'internet sur le marché du travail français. Outre le domaine empirique, qui est peu couvert par les travaux portant sur les impacts économiques et sociaux de l'internet, l'enjeu de la thèse est d'explorer les façons dont le nouveau média modifie le format des interactions et les modes d'évaluation sur le marché du travail. Il convient, à cet égard, de compléter l'approche centrée sur les coûts de recherche d'information par une réflexion sur la coordination par les qualités. En premier lieu, nous nous interrogeons sur la capacité de l'internet à réduire les frictions sur le marché du travail. D'un point de vue théorique, la baisse des coûts de recherche devrait se traduire par une amélioration du mécanisme global d'appariement ; cependant, les tests empiriques ne confirment pas ces prédictions. Ce résultat nous conduit à focaliser notre attention sur les intermédiaires du marché du travail positionnés sur l'internet. Nous nous intéressons à l'interaction stratégique des intermédiaires, dans une perspective d'économie industrielle. Nous montrons que les externalités de réseau et l'incertitude qualitative, qui jouent un rôle déterminant dans la structuration des marchés numériques du travail, engendrent des frictions.
Il convient, dans un deuxième temps, de considérer la façon dont les technologies de coordination construites par les intermédiaires contribuent à réduire l'incertitude à laquelle font face les agents. Nous nous appuyons sur l'analyse statistique d'un échantillon de requêtes effectuées sur un moteur de recherche d'offres d'emploi pour montrer que l'internet permet d'améliorer le niveau d'information des agents, à condition que cette information soit structurée. Or, les technologies de coordination, qui permettent de structurer l'information pour la rendre exploitable, ne sont pas ‘neutres' car elles incorporent des modes de qualification du travail. Ce questionnement est approfondi, en lien avec les institutions du marché du travail. Nous développons un cadre d'analyse de la pluralité des formes d'intermédiation numérique en explorant les investissements nécessaires pour établir et stabiliser une technologie de coordination.

Full textAbstract:
This master's thesis is a grounded theory study of the development of the Internet as a tool for political action in Japan by groups and individuals producing web pages on the issue of history textbook reform. Through the analysis of 14 in-depth interviews, a framework is developed for understanding the role the Internet has taken in political action in Japan. As activists utilize the Internet in political activism, the Internet appears to be developing into an anchor for continuing political activism. For activists, the Internet is a central point of reference for both mass communication and interpersonal communication activities. The model indicates that the political alignment of an activist is an important factor in determining his or her preference for either interpersonal or mass communication on the Internet. Activists on the left tend to use the Internet as a tool for interpersonal communication and coordination, while activists on the right tend to view the Internet as a tool for mass persuasion. The model of Internet activism developed in the thesis is also compared with models of communication derived from theories of technological determinism and social shaping of technologies. Consistent with technological determinist ideas, the Japanese case demonstrates that as activists rely on the Internet, other media show signs of becoming content for the new medium. However, the Japanese case also shows that pre-existing needs and the political framework of an activist have a strong shaping effect on Internet use, indicating the importance of a social shaping of technologies approach.

L'usager des sites internet des bibliothèques universitaires franÇaises ne peut que constater la très grande hétérogé neité des portails qui lui sont offerts.

Notre hypothèse est que leurs concepteurs manquent manifestement d'une référence qui oriente l'élaboration des portails des bibliothèques universitaires vers un modèle spécifique d'information et de communication. Ce constat nous a amené à consacrer la présente étude a cette question avec pour objectif de tenter de déterminer un ensemble de critères d'évaluation, quelques principes d'ergonomie, ainsi que les fonctionnalités les plus nécessaires, à notre avis, pour une conception efficace des portails de bibliothèque universitaire. En outre, nous avons essayé de présenter un schéma des différents composants d'un portail de bibliothèque universitaire préfigurant un modèle exhaustif à recommander. L'étude menée dans le cadre de cette recherche se veut exhaustive. Elle est fondée sur l'examen de tous les portails de services communs de la documentation et des bibliothèques universitaires franÇaises, au nombre de quatre-vingt-cinq. Nous nous sommes interrogés systématiquement sur leurs principes de construction, sur les types de contenu qu'ils proposent ; nous avons essayé systématiquement d'evaluer leur degré d'efficacité au regard de l'accès aux ressources documentaires et de la qualité des services associésThe user of internet sites of the french university libraries can only note the very great heterogeneity of the portals which are offered to him. They as well have as a whole a great diversity on the plan of their design as on that of the contents. Our assumption is that their originators obviously miss reference which directs the development of the portals of the university libraries towards a specific model of information and communication. This report led us to devote the present study at this question with for objective trying to determine a whole of criteria of evaluation, some principles of ergonomics, as well as the functionalities most necessary, in our opinion, for an effective design of the portals of university library. Moreover, we tried to present a diagram of the various components of a university portal of library preceding an exhaustive model to recommend. The study undertaken within the framework of this research wants to be exhaustive. It is founded on the examination of all the portals of common services of documentation and the french university libraries, with the number of eighty-five. We wondered systematically about their principles of construction, on the types of contents which they propose; we systematically tried to evaluate their degree of effectiveness in comparison of the access to the documentary resources and the quality of the associated services

Full textAbstract:
Context. Internet of Things (IoT) is an extension of the Internet, which now includes physical objects of the real world. The main purpose of Internet of Things is to increase a quality of people’s daily life. A smart home is one of the promising areas in the Internet of Things which increases rapidly. It allows users to control their home devices anytime from any location in the world using Internet connectivity and automate their work based on the physical environment conditions and user preferences. The main issues in deploying the architecture of IoT are the security of the communication between constrained low-power devices in the home network and device performance. Battery lifetime is a key QoS parameter of a battery-powered IoT device which limits the level of security and affects the performance of the communication. These issues have been deepened with the spread of cheap and easy to use microcontrollers which are used by electronic enthusiasts to build their own home automation projects. Objectives. In this study, we investigated wireless communication technologies used in low-power and low-bandwidth home area networks to determine which of them are most suitable for smart home applications. We also investigated the correlation between security, power consumption of constrained IoT device, and performance of wireless communication based on a model of a home automation system with a sensor node. Sensor node was implemented using Arduino Nano microcontroller and RF 433 MHz wireless communication module. Methods. To achieve the stated objectives of this research following methods were chosen: literature review to define common applications and communication technologies used in a smart home scenario and their requirements, comparison of wireless communication technologies in smart home, study of Arduino microcontroller technology, design and simulation of a part of home automation project based on Arduino, experimental measurements of execution time and power consumption of Arduino microcontroller with RF 433 MHz wireless module when transmitting data with different levels of security, and analysis of experimental results. Results. In this research, we presented a detailed comparison of ZigBee, WiFi, Bluetooth, Z-Wave, and ANT communication technologies used in a smart home in terms of the main characteristics. Furthermore, we considered performance, power consumption, and security. A model of a home automation system with a sensor node based on Arduino Nano was described with sleep management and performance evaluation. The results show that the battery lifetime of Arduino in a battery-powered sensor node scenario is determined by the communication speed, sleep management, and affected by encryption. Conclusions. The advanced communication strategy can be used to minimize the power consumption of the device and increase the efficiency of the communication. In that case, our security measures will reduce the productivity and lifetime of the sensor node not significantly. It’s also possible to use symmetric encryption with smaller block size.

Full textAbstract:
Cette thèse étudie les éléments constitutifs d'une organisation socio-économique émergente, et relativement spécifique à Internet, dont les portails porteraient la marque. Notre recherche est menée à travers l'étude des multiples tentatives de structuration du marché des services sur Internet entre 1993 et 2004. L'hypothèse principale est que le modèle socio-économique sur Internet se forme autour du concept de " guichet unique ". Il apparaît, au terme de l'analyse, que la fonction centrale de l'intermédiation sur Internet se construit soit autour des ressources outillées d'accès et de guidage à la manière intégrée et fermée des métamédiateurs, soit autour des acteurs spécialisés dans les ressources outillées de mise en relation, et ces acteurs sont alors qualifiés d'inframédiateurs. Dans les deux cas, une organisation socio-économique qui aménage le modèle éditorial, le flot, le kiosque, le club et le courtage est caractéristique du modèle d'intermédiation sur InternetThe present thesis examines the components of an original socio-economic organizational model specific to the Internet which is represented through portals. The study considers various attempts at Internet services market structuring in the time period between 1993 and 2004. The core assumption is that a socio-economic model of the Internet is based on the concept of the one-stop service-provider. The crucial function of the Internet, namely that of intermediator, is carried out either by "metamediators" operating in an integrated and proprietary environment based on access and guidance resources or by "inframediators" specializing in mediation resources. The prescriber function, aggregating content and service providers function, concentration of revenues function, access function, as well as trusted third-party function are developed individually by these two categories of market players. In either case, a specific socio-economic organization emerges
