Du "non-public" d’un Centre de culture scientifique aux appropriations des sciences et techniques
2011
National audience; Dans le cadre d'une recherche de doctorat, nous abordons la place et l'image du musée parmi d'autres pratiques culturelles consacrées aux sciences et tech- niques, dans le quotidien des publics et des « non-publics » de la structure. En proposant une analyse centrée sur les publics individuels des expositions mais aussi des manifestations hors-les-murs, nous nous interrogeons sur les formes d'appropriations non-formelles et informelles des sciences et techniques, et sur la mise en perspective de la visite de ce type d'institution muséale, en mobilisant de façon complémentaire des techniques d'enquêtes quantitatives (question- naires, statistiques) et qualitatives (entreti…
« Quelle exposition, quel média, et pour quel public ? »
2003
L'article revient sur la question de la mise en exposition différenciée selon les acteurs qui les mettent en oeuvre et leur représentation des finalités d'une exposition

Memories of video gaming culture on YouTube
2016
Within the patrimonialization of video gaming, the status of memory representations is still unknown. On YouTube, amateur video makers present games from the 1970s through to the 1990s, combining voice and screencast. By reviewing these low audience channels and interviewing their creators, we have tried to understand the current trends in amateur videos. The ensuing results highlight the diversity of the relationship to memory. Productions are supported by a seminal viewer practice (Web, TV), and a diversified frame: recreational computing, conservation, web archives, emulation. The momentum provided by this nostalgia interfaces with a critical discourse; Becoming a video maker generates a…

La selección de las noticias en el entorno de un centro de documentación de información de actualidad
2002
In information retrieval systems operation, lack of adequate selection criteria originates information overload and has negative consequences in relevance judgments. In the context of a news reference service, three leveis in the selection process are proposed. The first one relates to the type of sources covered by the system, the second set of criteria determines which publications are included in the process of document analysis. The last one applies to the selection of individual documents based on their informative content. La falta de criterios idóneos de selección puede provocar un grave problema de saturación informativa, lo que repercute negativamente en la búsqueda posterior de in…
Very narrow quantum OBDDs and width hierarchies for classical OBDDs
2014
In the paper we investigate a model for computing of Boolean functions - Ordered Binary Decision Diagrams (OBDDs), which is a restricted version of Branching Programs. We present several results on the comparative complexity for several variants of OBDD models. - We present some results on the comparative complexity of classical and quantum OBDDs. We consider a partial function depending on a parameter k such that for any k > 0 this function is computed by an exact quantum OBDD of width 2, but any classical OBDD (deterministic or stable bounded-error probabilistic) needs width 2 k+1. - We consider quantum and classical nondeterminism. We show that quantum nondeterminism can be more efficien…
IT engagement as a blessing and a curse? Examining its antecedents and outcomes in organizations
2020
Information technology (IT) engagement is defined as a need to spend more time using IT. Practice-based examples show that IT engagement can have adverse effects in organizations. Although users can potentially get more work done through IT engagement, observations show that the users might jeopardize their well-being and hamper their work performance. We aimed to investigate this complexity in the research on IT engagement by examining its potential antecedents and outcomes in organizations. Considering the potentially mixed outcomes, we developed a model to examine the effects of IT engagement on personal productivity and strain. We also aimed to explain the antecedents of IT engagement b…
Arts et créations au prisme des TIC
2015
International audience; Les noces entre l'art et la technique sont anciennes et la technique apparait tour a tour objet, sujet et support de la creation, mais aussi de diffusion et de circulation sociale de l'art. Les approches esthetiques et semiologiques ont rarement pris la mesure de la dimension communicationnelle de cette rencontre. Au-dela des objets-oeuvres ainsi produits, cet ouvrage presente les recherches sur les reconfigurations que le numerique apporte a ces pratiques creatives.
