Taïwan, ou De la difficulté à faire entendre sa voix à l'heure d'Internet
2009
Malgre une democratisation reussie, une economie florissante et un libre acces a Internet, Taiwan reste largement absent de l’espace public international. Cette absence resulte de la politique subtile menee par la Chine. La strategie de Pekin consiste a concentrer l’attention des acteurs internationaux et dans le meme temps a effacer toute trace de Taiwan dans l’espace public en tant que pays independant (dans les organisations internationales comme dans les medias). L’article suggere que Taiwan ne renforcera sa position que par l’intensification des negociations directes avec la Chine continentale. L’exemple taiwanais eclaire un peu plus les strategies regulatrices des Etats en reponse aux…
: Looking through the gaps of the digital divide in Higher education
2007
A partir de una muestra de 719 estudiantes de la Universidad de Chile en 2004, este artículo analiza las diferencias existentes respecto de capitales culturales materiales e incorporados relacionados con el acceso y uso de las nuevas tecnologías de la información y comunicación (NTICs). Bajo diferentes métodos de análisis cuantitativo se pone de manifiesto la existencia de niveles de brecha digital para tales herramientas, brecha que estaría relacionada especialmente al género pero también a la condición socioeconómica. Esta última variable, aunque presente, muestra efectos más bien indirectos no pareciendo influir en las actitudes y disposiciones de los estudiantes respecto al uso de las N…

Towards better privacy preservation by detecting personal events in photos shared within online social networks
2015
Today, social networking has considerably changed why people are taking pictures all the time everywhere they go. More than 500 million photos are uploaded and shared every day, along with more than 200 hours of videos every minute. More particularly, with the ubiquity of smartphones, social network users are now taking photos of events in their lives, travels, experiences, etc. and instantly uploading them online. Such public data sharing puts at risk the users’ privacy and expose them to a surveillance that is growing at a very rapid rate. Furthermore, new techniques are used today to extract publicly shared data and combine it with other data in ways never before thought possible. Howeve…
Information retrieval in digital documents : a variation patterns of procedural execution
2013
The research activity of information on the internet has become common in our daily life. Despite this fact, it still raises many problems for the user who does not find the information they want or is lost to the amount of information available. This study aims at testing a new patented preview device, enabling users to browse and view pages in depth. The task is to find a target apartment with one or more specific criteria in a real estate agency designed website. Several conditions were tested. The “usual” condition with the classic search features, page by page, the other "transparent" condition which enables you to preview selected pages and select only relevant pages. We are intereste…

Contribution to the development and the improvement of a digital model of the human body biofidelic HUByx by numerical methods for impact applications
2017
The study of human tolerance thresholds to impacts requires experiments on living or post mortem human subjects, which naturally raises ethical questions. To overcome these limitations, the development of numerical tools has led over the last few years to the implementation of numerical models more or less capable to accurately reproduce the mechanical behavior of the human body when subjected to various types of stresses. It is in this context that the numerical model HUByx (Hermaphrodite Biomechanics yx-model) has been developed within the research department COMM of the ICB lab at UTBM. This PhD work aims at validating and improving the biofidelity of the thoracic part of the HUByx model…

Usages du TBI par les enseignants et compétences numériques des élèves d'école élémentaire : quelle mise en perspective ?
2018
International audience; On assiste en France depuis plusieurs années à une implantation progressive du tableau blanc interactif dans les écoles primaires. Cet outil serait susceptible d'augmenter la réussite des élèves en améliorant la pratique pédagogique des enseignants, en faisant varier la nature des ressources pédagogiques et en augmentant l'interactivité dans la classe (Karsenti, 2016). Néanmoins, les travaux étudiant le rôle du TBI sur les acquisitions des élèves se font encore rares, particulièrement dans le cercle de l'Hexagone. En conséquence, cette contribution vise à analyser l'efficacité du TBI à l'école élémentaire, en examinant ses effets sur les compétences numériques des él…
Dissimilar joining of copper to stainless steel and TA6V to stainless steel by high power beams : understanding and modeling of physicochemical pheno…
2010
The present study is dedicated to the comprehension of the mechanism of materials mixing during dissimilar welding by high power beam sources. We have been interested in joining of two couples of metallic materials which present different metallurgical problems: •copper- stainless steel (miscibility gap, important difference in physical properties);•TA6V- stainless steel (oxidation on air, formation of intermetallic phases which made the joint brittle).For the first couple of materials, continuous laser Nd:YAG welding and electron beam welding have been applied. The experimental study of morphology evolution, composition, microstructure and mechanical properties has allowed establishing the…
