Depuis 1997, l’espace socio-public camerounais « devient média » (Blondeau, 2007) de plus en plus. Dans ce processus, la politique ne fait pas exception. Au contraire, les partis et leurs leaders investissent l’Internet, le territorialisent et en utilisent les outils : sites web et blogs, forums, facebook, twitter, myspace, etc. Cela apparaît techno-politiquement innovant dans un contexte certes marqué par le multipartisme, la libéralisation de l’espace sociopolitique et l’avènement des NTIC, mais qui présente aussi des déficits. Politiquement, on note une opposition en panne, des élections contestées et une faible culture de participation politique. (Ahmadou, 2006; Mack-Tit, 2007; Kokoroko, 2009). Au plan sociotechnique et économique, le taux de pénétration de l’Internet (4%) et le pouvoir d’achat de 70% de la population restent faibles. Cela limite l’accès au Net (Bâ, 2003) mais n’empêche pas son usage et sa représentation politiques. Nous avons étudié cet usage et cette représentation au niveau macro-politique en nous limitant aux acteurs institutionnels. Nous avons alors remarqué que leur cyberprésence c’est-à-dire la façon dont ils s’approprient l’espace numérique tend à reproduire leurs rapports de force dans le champ politique classique (Ovadia, 2011). Les usages politiques qu’ils y développent traduisent davantage la diffusion de l’information que l’interactivité et la mobilisation (Greffet et Wojcik, 2008). Dans ce contexte, les enjeux démocratiques de net-politique varient selon le caractère « opposant » ou « au pouvoir » des acteurs (Greffet, 2011). Si pour le parti au pouvoir, il s’agit de dominer tous les espaces d’expression politique, pour les opposants, le but est de trouver une visibilité nationale et de se faire entendre à l’international. Pour mener ce travail, nous avons examiné trois points : la cyberprésence des acteurs institutionnels, le contenu de leurs sites web et blogs et celui de leurs pages facebook. Nous situant dans la perspective de la communication médiatisée par ordinateur (Yanoshevsky, 2010), nous avons alors utilisé les indicateurs que Bastien et Greffet (2009) et Béché (2011) ont utilisés dans leurs travaux sur la net-campagne.

La crise économique et financière que nous traversons depuis deux ans ne diffère en rien de celles que notre monde a connues au cours de sa longue histoire (Malkiel, 2000). De tels ajustements sont nécessaires chaque fois que notre système économique doit s’adapter à des changements technologiques majeurs. La longueur atypique de cette crise et son ampleur - plusieurs milliers de milliards de dollars de capitalisation boursière perdus – soulignent toutefois l’importance exceptionnelle des ajustements qu’engendrent l’adoption et la diffusion de ces technologies nouvelles.

Using a sociological approach, we show how Tunisians of the diaspora take advantage of Internet to keep themselves involved and informed and to denounce what they consider as unjust in their native country. We describe the style of critical speech preferred by these activist Internet users and the type of public sphere they claim. We study the activist paths of some of them and analyse their relationships with Internet users living in Tunisia. While they are initially less likely to openly denounce (use of indirect criticism) the authoritarian regime, we illustrate how these Internet users in Tunisia come to play an increasingly important role in this new space of contestation.

The article specifies the meaning of “self-regulated learning”, then illustrates, first in course then in a program, a few practices using Internet as a support for learning. It underlines in those practices the growing importance of self-regulated learning. It advocates for supporting, mentoring the students in their development of that self-regulation, often implicit and considered granted in the Internet based course environments. [less ▲]

Après avoir introduit le thème du contrôle par l’étudiant de son propre apprentissage, la conférence illustrera des situations d’apprentissage et d’évaluation (bien sûr faisant usage d’Internet) qui poussent l’étudiant à faire des choix et qui, en corollaire, aboutissent à faire valider par les enseignants le résultat de trajectoires riches et différenciées. Rassembler des preuves de son développement de compétences, planifier son inscription dans une série de MOOCs ou son travail en ligne suite à un test diagnostique sont autant d’actions qui responsabilisent l’étudiant quant à sa propre formation.

Since the nineties, the Internet has seen an impressive growth, in terms of users, intermediate systems (such as routers), autonomous systems, or applications. In parallel to this growth, the research community has been looking for obtaining and modeling the Internet topology, i.e., how the various elements of the network interconnect between themselves. An impressive amount of work has been done regarding how to collect data and how to analyse and model it. This chapter reviews main approaches for gathering Internet topology data. We first focus on hop limited probing, i.e., traceroute-like probing. We review large-scale tracerouting projects and discuss traceroute limitations and how they are mitigated by new techniques or extensions. Hop limited probing can reveal an IP interface vision of the Internet. We next focus on techniques for aggregating several IP interfaces of a given router into a single identifier. This leads to a router level vision of the topology. The aggregation can be done through a process called alias resolution. We also review a technique based on IGMP probing that silently collect all multicast interfaces of a router into a single probe. We next refine the router level topology by adding subnet information. We finish this chapter by discussing the AS level topology, in particular the relationships between ASes and the induced hierarchy. [less ▲]

Since the beginning of the nineties, the internet has undergone impres- sive growth. This growth can be appreciated in terms of the equipment, such as routers and links, that has been added, as well as in the numbers of users and the value of commerce that it supports. In parallel to this expansion, over the past decade the networking research community has shown a growing interest in discovering and analyzing the internet topology. Some researchers have developed tools for gathering network topology data while others have tried to understand and model the internet’s properties. These efforts have brought us to a crucial juncture for toplogy measurement infrastructures: while, previously, these were both small (in terms of number of measurement points) and monolithic, we are starting to see the deployment of large-scale distributed systems composed of hundreds or thousands of monitors. As we look forward to this next generation of systems, we take stock of what has been achieved so far. In this survey, we discuss past and current mechanisms for discovering the internet topology at various levels: the IP interface, the router, the AS, and the PoP level. In addition to discovery techniques, we provide insights into some of the well- known properties of the internet topology. [less ▲]

Despite the numerous health benefits, population physical activity (PA) levels are low and decline with age. In Belgium, people older than 60 years will represent more than a third of the entire population in 2050, with some major implications in terms of public health cost. Faced with this issue, innovative interventions to promote PA in older adults are of major interest. The Internet holds potential for delivering effective PA interventions. Besides, older adults are the largest-growing group of Internet users. Therefore, the main purpose of this study was to explore the opinion of older adults about Internet-based PA promotion. First, 75 older adults (73.75 ± 5.77 years) fulfilled a questionnaire about their PA stage of change, motivation about PA and opinion about several elements that could be included in an Internet-based PA website. Then, they were asked to participate in an unique session of “home exercising”. Finally, in a subsequent interview, they had to give their opinion about the inclusion of this kind of session in an Internet-based PA website. Only 48% of the participants met the official guidelines for PA. A regular access to the Internet was observed for 57.3% of the participants, with a significantly higher access for the younger ones (p = .014). Based on a 4-point Likert scale, the most popular topics for an Internet-based intervention were “PA social forum” (3.3/4), “PA local opportunities” (3.2/4), “PA local agenda” (3.1/4), “Benefits of PA” (3.1/4) and “PA programs” (3.1/4). According to the participants, the inclusion of “home exercising” in an internet-based PA website would be appreciated (7.85/10), adapted (8.78/10) and likely to be self-implemented at home (6.96/10). Findings suggest that an internet-based PA promotion may be acceptable for older people. Social and neighborhood environment elements appear to be essential in order to support the motivation for a regular PA practice. [less ▲]

In 1982, we developed a new coma scale, the Glasgow-Liege scale, which combines the quantified analysis of five brain stem reflexes with the Glasgow methodology. The present study was undertaken to determine to what extent agreement exists among different raters assessing brain stem reflexes (Parameter R) and to compare the results with those observed from motor responses (Parameter M). We show the good agreement achieved by different examiners in the evaluation of brain stem reflexes. Brain stem reflexes offer a slightly higher agreement (kappa = 0.69) than that of the study of motor response (kappa = 0.65). Within Parameters M and R, we observed less agreement in the evaluation of flexion responses and in the interpretation of oculocephalic reactions. The reliability of the evaluation of M and R parameters justifies the use of the Glasgow-Liege scale as a means for evaluating disturbances of consciousness. [less ▲]

Data from the Far Ultraviolet Imager (FUV) on the Imager for Magnetopause-to-Aurora Global Exploration (IMAGE) satellite show that subauroral proton arcs appear in the afternoon sector during geomagnetically disturbed periods when the interplanetary magnetic field rotates either from south to north or from west to east and when the magnetosphere is moderately compressed. Time series of proton aurora images show that the proton emissions are generally aligned along the equatorward part of the auroral oval. However, when interplanetary magnetic field (IMF) B[SUB]z[/SUB] changes from negative to positive the auroral oval contracts toward higher latitudes while the ring current proton precipitation remains stationary, resulting in a separation of several degrees between the latitude of the new oval position and a subauroral proton arc in the afternoon sector. A similar effect occurs when IMF B[SUB]y[/SUB] rotates from negative to positive, in which case the oval in the afternoon sector retreats toward higher latitudes, again leaving a separation between the oval and the subauroral proton arc of several degrees. Comparisons with low-altitude and geosynchronous satellite data show that the subauroral proton arc is caused by the precipitation of protons with energies from several keV to 30 keV and is likely associated with the existence of a plasmaspheric ``drainage plume.'' In contrast, the proton emissions along the main oval are caused by protons with energies generally less than 10 keV. [less ▲]
