Espace public numérique et participation politique

2015

International audience; L’arrivée massive des technologies de l’information et de la communication et la démocratisation d’Internet dans la vie quotidienne ont restructuré notre société. La relation aux autres se trouve reconfigurée par l’émergence de nouvelles formes de communication interpersonnelle et communautaire, désormais fréquemment « assistée par ordinateur ». La différence réside dans l’échelle des valeurs engendrées (nombre d’individus en contact, pluralité des individus, nature des informations…) et particulièrement dans la puissance du canal de communication qui brouille les frontières de l’espace public, modifie les temporalités et réinterroge la participation politique et cit…

Le Réseau de pépinières de revues scientifiques REPÈRES : un révélateur de la complémentarité des métiers de l'infodoc et de l'édition

2020

The professional network "REPÈRES", created in 2018, aims at federating the open access scientific journals incubators and strengthening best practices around open access publishing in accordance with national policies promoting open access to science. The network shows evidence of convergence of practices from documentation and publishing professionals, resulting from the stimulus created by open access.

Knowledge engineering and semantic formalism of symbolic relations. From medieval network to web 3.0

2020

A search has always been at the center of human concerns, the one of conditions and means to represent, to control well, and to communicate effectively with his environment. While technological advances and electronic gadgets such as smartphones, the Web, and online social networks currently allow addressing this concern, it has not always been the case. Our works in this thesis treat medieval documents considered as a medium of communication and as a model of the social network in the Middle Ages. These documents are called medieval illuminations. They were luxurious paintings used in that time to represent the environment and ideal world for elites such as prince, duke, etc. Those paintin…

Découverte et analyse des communautés implicites par une approche sémantique en ligne : l'outil WebTribe

2012

With the rise of Web 2.0 and collaborative technologies that are attached to,the Web has now become a broad platform of exchanges between users. The majorityof websites is now dedicated to social interactions of their users, or offerstools to develop these interactions. Our work focuses on the understanding of theseexchanges, as well as emerging community structures arising, through a semanticapproach. To meet the needs of web analysts, we analyze these community structuresto identify their essential characteristics as their thematic centers and centralcontributors. Our semantic analysis is mainly based on reference light ontologiesto define several new metrics such as the temporal semantic…

Digital socialization in a Territorial Intelligence case: The Fontaine d'Ouche area in Dijon (Burgundy, France).

2013

How to mobilize citizens around eco-responsible conducts? With the "Transition Towns MOVIDA" project (http://programme-movida.fr), we wish to identify levers related to a most sustainable consumption, in reference to the Transition initiated by Rob Hopkins. The present proposal consider all possible "socio-technical communicational" devices that can support the socio-ecological transition in a local area such as Fontaine d'Ouche in Dijon: reflexivity spaces (fear and hopes, actions and attitude) in a dialogical base for decisionmaking (at individual and collective level). What kind of ICT devices should allows inhabitants of the Fontaine D'ouche area to be more resilient? In this case, how …

Émergence d’un réseau de recherche au service de la Transition en Bourgogne

2016

National audience; Au sein du programme Movida, l’ambition du projet « Fontaine d’Ouche en transition » était d’identifier les leviers d’une consommation plus durable en articulant plusieurs approches disciplinaires qui entendaient éclairer les dimensions psycho-sociologiques et communicationnelles de la consommation sans négliger les aspects géographiques et économiques.Le projet « Ville en Transition MOVIDA » (V(e)T) a été à l’origine d’une véritable dynamique de recherche et d’innovation qui s’est constituée en Bourgogne sur le thème de la transition socio-écologique. Souhaitée par l’ADEME Bourgogne dans un souci d’accompagnement de l’innovation sociale durable sur le territoire bourguig…

Signaux qualitatifs et phénomène de star

2000

The superstar phenomenon describes a situation wherein few artists dominate the activity in which they engage and earn significant amounts of money. Most of models, trying to explain this phenomenon, take place clearly on the product market where artists provide ultimate and consumers. We adopt here a different approach by taking place on the labour market regrouping artists (whose the services are production factors) and employers (the producers of cultural products) and we demonstrate that die strategies, consisting in minimizing search costs under contraint of quality maximisation, can work towards explaining the emergence of a very unequal distribution of artistic incomes. In order to m…

The vehicle as a source and consumer of information : collection, dissemination and data processing for sustainable mobility

2014

Today, vehicles have become more sophisticated, intelligent and connected. Indeed, they are equipped with sensors, radars, GPS, communication interfaces and high processing and storage capacities. They can collect, process and communicate information related to their working conditions and their environment forming a vehicular network. The incorporation of communication technologies on vehicles garnered a huge attention of industry, government authorities and standardizations organizations and opened the way for innovative applications that revolutionized the automotive market with the main goals to ensure safety on roads, increase transport efficiency and provide comfort to drivers and pas…

Classification of spectra and search for biomarkers in prostate tumours from proton nuclear magnetic resonance spectroscopy

2010

Prostate cancer is the most common cancer in men over 50 years. Current detection methods either lack sensitivity or specificity or are unpleasant for the patient. Magnetic resonance spectroscopy allows the study of metabolism in vivo. The use of a high field machine (≥3T) has allowed us to dispense with the use of an endorectal coil, which is particularly uncomfortable for the patient. The objective of this thesis is to create an automatic method to detect cancer by processing data obtained through magnetic resonance spectroscopy MRS is a complex phenomenon, very sensitive to acquisition conditions. Firstly, we have studied how to improve and optimise signal acquisition. However, even with…
