International audienceThe topic of trust in information technology (IT) artifacts has piqued interest among researchers, but studies of this form of trust are not definitive regarding which factors contribute to it the most. Our study empirically tests a model of trust in IT artifacts that increases our understanding in two ways. First, it sets forth two previously unexamined system quality constructs-navigational structure and visual appeal. We found that both of these system quality constructs significantly predict the extent to which users place trust in mobile commerce technologies. Second, our study considers the effect of culture by comparing the trust of French and American potential users in m- commerce technologies. We found that not only does culture directly affect user trust in IT artifacts but it also moderates the extent to which navigational structure affects this form of trust. These findings show that system quality and culture significantly affect trust in the IT artifact and point to rich possibilities for future research in these areas

National audienceIn this paper, we examine how public middle-managers exercise human agency during an information system (IS) implementation process and how this helps producing changes on the field. Drawing on strategic actor theory (Crozier et Friedberg 1977), we suggest system constraints emanate from middle-managers willingness to adopt "winning" scenarios for action, in which they would contribute to modernizing public administration. We then argue that these actions allow IT to be implemented in practically acceptable ways.Cet article traite des réponses de responsables d'unités locales d'une administration publique face au changement suivant l'implémentation d'un système d'information (SI) intégré. En nous fondant sur la théorie de l'acteur stratégique (Crozier et Friedberg 1977), nous soutenons que les contraintes du SI émanent de la volonté de ces responsables d'adopter des scénarios d'action de nature à leur permettre de contribuer à la modernisation de l'administration publique tout en renforçant leur rôle. En outre, nous montrons que ces actions permettent d'implémenter le SI de façon acceptable sur le terrain

Research in sociology of tourism indicate that people increasingly engage in cultural activities. They search for enjoyment and authentic experiences. Meanwhile, cultural places such as museums tend to rely on Information Technologies (IT) to support the exhibition of cultural artifacts and communications with the public. This research tries to fill in the gap by questionning the persistance of authenticity and its emotional benefits in IT-mediated environments, such as websites. Our research questions are the following: what role does authenticity play in online environment? What is the influence of website design on perceptions of authenticity? In order to test our eight hypotheses, a free simulation experiment was conducted on the website of a French art museum. Overall, 150 questionnaires were completed. The results of this research contribute to the Human-Computer Interaction field. We also offer practical guidance to museum website designers.
