The ever-growing amount of data available on the Internet
calls for personalization. Yet, the most effective personalization
schemes, such as those based on collaborative
filtering (CF), are notoriously resource greedy.
We argue that scalable infrastructures should rely on P2P design
to scale to that increasing number of users, data and dynamics.
I will present a novel scalable k-nearest neighbor protocol, which P2P flavor provides
scalability by design. This protocol provides each user with
an implicit social network composed of users with similar tastes in a given application.
This protocol has been instanciated in various settings:
(1) A P2P system, WhatsUp, a collaborative filtering system for disseminating
news items in a large-scale dynamic setting with no central authority;
(2) A hybrid recommendation infrastucture HyRec, an online cost-effective scalable
system for CF personalization, offloading CPU-intensive recommendation
tasks to front-end client browsers, while retaining storage
and orchestration tasks within back-end servers;
(3) A cloud-based centralized recommendation engine.
Experiment show that our solution outperforms alternatives with respect to cost
while maintening the quality of personalization. Mot(s) clés libre(s) : réseau social, P2P, internet du futur, infrastructure évolutive, gestion de ressources, personnalisation

Sans doute vous arrive-t-il fréquemment de vouloir obtenir quelque chose d'autrui. Vous voulez que votre voisin s'occupe de votre chien, que votre fille pratique votre sport favori, que vos amis viennent manifester avec vous, etc.Comment vous y prenez-vous ?Vous pouvez exercer votre pouvoir mais encore faut-il que vous en ayez.Vous pouvez convaincre, mais encore faut-il que vous soyez doué pour la persuasion.Vous pouvez aussi manipuler et cela ne demande que l'apprentissage de certaines techniques.Ces techniques, on les connaît, elles font l'objet, depuis plusieurs décennies, d'importantes recherches. On en parle peu en France, probablement par pure pudibonderie, à moins que ce ne soit pour mieux les réserver aux manipulateurs professionnels. Mot(s) clés libre(s) : influence, manipulation, persuasion, psychologie sociale

La modernisation du système de soin

Tous les acteurs du système de soin, pouvoirs publics, assurance maladie, soignants et assurés, ont pris conscience de l'obsolescence du système de soin tel qu'il a été essentiellement défini en 1930 pour la médecine libérale et en 1958 pour les soins hospitaliers. Sont en cause notamment le découpage entre ces segments de la chaîne de soins ainsi que le rôle que chacun exerce mais aussi les rapports entretenus avec les patients et la nature des prestations prises en charge. Le système du XXIème siècle, pour rester solidaire, devra être transparent, sélectif et permettre à l'individu - praticien ou patient - d'être responsable. Mot(s) clés libre(s) : coordination, internetsanté, relationnel, responsabilité, sécurité sociale, soin

L'individu a été longtemps encadré par des systèmes de valeurs qui donnaient du sens à sa vie. Il était inséré dans des groupes organisés : la famille, l’usine, le syndicat, le parti... Il était établi dans des lieux : le quartier, la commune, le village... Cela produisait un individu relativement sécurisé, disposant d’une place (pas toujours choisie) dans la société.Aujourd’hui, ce système s'est désagrégé. Les relations doivent obéir au principe de la satisfaction et du libre choix. Mais l'individu y a gagné en liberté et en autonomie. Mot(s) clés libre(s) : autonomie, diversité sociale, ENS Lyon, Gérard Wormser, groupes organisés, individu, insécurité, Les conférences du Grand Lyon 2006-2007, liberté, libre choix, Marie-Christine Jaillet, mixité, sécurité, ségrégation urbaine, système de valeurs, ville

Mixité, an urban and housing issue : introduction au colloque [version originale] / Marie-Christine Jaillet, Jean-Claude Driant. In "Mixité : an urban and housing issue? Mixing people, housing and activities as urban challenge of the future", 23ème colloque international de l'European Network for Housing Research (ENHR), organisé par le Laboratoire Interdisciplinaire Solidarités, Sociétés, Territoires (LISST) à l'Université Toulouse II-Le Mirail, 5-8 juillet 2011. 1. Debating around ‘Mixité’ in Toulouse: An appropriate place to speak of it / Marie-Christine Jaillet The term 'Mixité', most often qualified by either 'functional' or 'social', has taken on a prominent position in the field of public policies on housing. It has come to represent the antidote to social or ethnic segregation as well as the trend in urban zoning that has separated housing, work places, and shops and services. Though researchers are very hesitant on a form of ideal 'mixité', one that is supposed to remedy the ills of contemporary society (segregation, ghettoisation, the dislocation of social ties, matching with its peers), they are even more dubitative on the normative or prescriptive dimension of social mixity’s injunction, one that inspires a certain number of public policy’s dispositions. Nevertheless, in the name of mixity, myriad efforts are currently undertaken in urban contexts: for example, within urban renovation or regeneration policies, or in the framework of the redistribution of social housing. Though we can question the very pertinence of the notion of mixity and its ideological foundations, it is also interesting to consider what its implementation produces. Beyond its mobilizing effect, does it render the manner in which housing is organized more efficient and effective? What does it produce, 'side by side' situations or social interactions? Mobilizing in Toulouse academic debate from various European countries is all the more interesting Young metropolis, barely a millionaire city, with one of the highest rates of population growth in France, its urbain development is characterised by a more and more visible social space division. Toulouse embodies the paradox of metropolitan societies where the greater social diversity, a form of cosmopolitanism, generates distancing or avoidance attitudes or strategies rather than producing "friction" or interaction. In such a world, what could constitute a physical and metaphorical "common space"? It would have to be a space that allows cities to carry out their integrative functions, not through "fusion" or by overcoming differences, but rather through the emergence of a common identity and the capacity to live together. Metropolitan, social strategies of aggregation by affinity, whether territorial or reticular, do not necessarily oppose this process; but they do not really contribute to developing it either. How can public action help reestablish "convivienca" in our metropolitan era? By fighting against processes of self-segregation by imposing a "diversity" that is less and less accepted? Toulouse is attempting to address this question by struggling in the social housing neighborhoods against the processus of ghettoization and by developping solidarity policies that attempt to distribute social housing more evenly. The challenge for Toulouse is then to try to reduce the clubbization trends of the urban spaces and to produce, on a daily basis, if not a “mix” city at least a city that is socially "sustainable". 2. The housing situation in France: The main issues / Jean-Claude Driant The object of this opening presentation is the housing situation in France and the main issues of the current housing debate in France. With less than a year to go before the next presidential election, France is entering into an important political period and, judging from what party leaders have been saying so far, the housing crisis looks to be one of the main items on the agenda for this election year. We are going to try to understand why and pinpoint the principal subjects of the current housing debate. This presentation is in three parts: why has the issue of housing reemerged in the political debate?, why is the housing situation in France widely referred to as a crisis?, what are the most important issues to address in present and future housing policies? Those housing policy choices, in turn, involve answering four key questions: To what extent should efforts be made to promote owner-occupied housing? Is the French social housing model jeopardized by the pauperization of the population and by the right to housing now enshrined in French law? What policies might help regulate real estate prices and rents? To what extent should housing policies be decentralized in order to satisfy a very wide range of housing needs?
