International audienceThis study develops a conceptual framework for measuring the effectiveness of Internet-based 3D advertisements. The study uses an interdisciplinary literature review (marketing, information systems, and human-computer interaction) to enhance the understanding of the impact of using 3D visualisation in online advertisements, and to identify the most relevant conditions for application. The findings demonstrate the effectiveness of such ads in the case of a geometric product, as well as in the case of a material product. This study's results highlight the significance of telepresence as a mediator. The findings reveal that telepresence determines how ad format (2D versus 3D) influences the range of variables used to measure advertising effectiveness
This study proposes a conceptual model for understanding the impact of telepresence in an online ad on the process of forming attitudes towards the product. The model takes the traditional experiential approach as its frame of reference. It formulates two interdependent attitude formation processes in a telepresence situation: the first cognitive, the second affective. The model is tested by means of a quasi-experiment. The results confirm the hypotheses of direct and indirect causality among the variables comprising the two processes. This causal analysis allows us to carry out a conceptual diagnosis and to make various recommendations.
La recherche d’efficience reste une condition importante du succès des SI et de bonne gouvernance des TI liées à la performance individuelle, collective et organisationnelle. Son évaluation n’est pas simple et souffre d’une absence de consensus dans sa conceptualisation et sa mesure. Cet article contribue à l’étude de deux perspectives complémentaires, cognitive et affective, en relation avec la qualité des services SI perçus par les utilisateurs et leur satisfaction. Il propose un modèle conceptuel, extrait du méta-modèle de Delone et McLean (2003), qui postule l’influence des attentes individuelles (de services SI) sur les croyances (satisfaction). Ce modèle est confronté à une organisation ayant eu un fort développement de son infrastructure SI, et à l’ensemble des utilisateurs équipés d’un poste de travail avec de nombreuses applications (bureautiques et métiers). Les données, recueillies auprès de 495 individus, ont été traitées par une Modélisation en Equations Structurelles (MES) pour, en premier lieu, valider la structure des construits des deux niveaux conceptuels et, en second lieu, valider l’hypothèse générale de dépendance entre les variables endogènes de satisfaction et les variables exogènes de qualité des services. Les résultats restituent les dimensions postulées conceptuellement pour chacun des construits des deux échelles de qualité des services et de satisfaction. Ils vérifient l’hypothèse générale de causalités directes entre les variables des deux niveaux conceptuels, et valident, simultanément, le sens supposé de la causalité et le déterminisme postulé, mais jamais établi, de certaines dimensions de la qualité des services.
The success of wikis on Internet has led the organizations to introduce wikis within corporate settings for multiple purpose. However, despite the popularity of wikis in public and subsequently in the corporate environment, an empirical investigation of their benefits within organizations is still lacking. This study performs an empirical investigation with 177 corporate wiki end-users to evaluate their performance after wiki use. Enterprise wiki end-user performance is evaluated by measuring user's efficiency, effectiveness and capacity development. PROCESS macro in SPSS is used to empirically test specific indirect effects via mediation. The findings suggest that the collaboration quality, information quality, and system quality of enterprise wikis help its users in increased efficiency, effectiveness, and their capacity development.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
