本研究旨在探討網路信任問題，先從網路人類學研究方法開始，找出網路言論可信度的前置變數。根據質性研究結果，發現網站特質、發言人特質、言論內容為可能影響網路言論可信度之變數。並依據此結果進行初步的量化問卷調查，在380份有效樣本中找出明確的影響因素，再同時進行兩個實驗研究，以確認各主要變數間的關係。 研究發現，言論內容提供正面資訊或負面資訊、以及言論內容與發言網友之間熟識程度的交互作用將影響消費者對網路言論的信任程度；而產品特質之差異會干擾上述變數對網路言論信任的影響程度。 / In this research, we try to explore the determinants of online information trust and the relationships between information trust and product attitude. In Study 1, we explored the online information trust by a qualitative research method, Netnography, to understand and shape the basic rationale of the determinants of online information trust. Then we employed an empirical survey on consumers to examine the proposed determinants of online information trust. We ranked the relative trust levels of the determinants, and explored the moderating differences existing between experience goods and credence goods. In the last study, two experiments using 2 (message statements: positive vs. negative) × 2 (perceived social relationships: strong vs. weak) between group factorial design were conducted to examine the causal relations among determinants, online information trust, attitude, and purchase intention. The moderating effects of product categories were examined, too.

La diffusion de l’information sur internet est aujourd’hui assurée par une multiplicité d’acteurs avec en pointe des audiences les portails désignés aussi sous le concept flou d’infomédiaires. Leur émergence s’inscrit dans un mouvement de re-configuration de l’espace médiatique, impulsée par les Technologies de l’Information et de la Communication (TIC) (Internet et web2.0, particulièrement). La recherche présentée ici est partie d’un constat majeur concernant leur succès dès leur entrée en scène alors que les médias déjà établis peinent à établir des modèles éditoriaux et économiques viables sur Internet.Nous considérons que des stratégies d’acteurs sont observables au cœur de la filière en construction de l’information en ligne et qu’il existe une redéfinition des rôles autour de la production, de la diffusion et de la consommation de l’information accentuée par le phénomène de la convergence. L’étude envisage ces stratégies d’acteurs comme participant à une reconfiguration de l’espace médiatique numérique, dominé par les portails, dont la démarche consiste à s’appuyer de façon « stratégique », sur des contenus et des pratiques certifiés professionnels des éditeurs de presse, et de façon « tactique », sur les logiques marketing, afin de proposer de nouveaux modèles à la fois « éditorial et économique» assez innovants, adaptés aux mutations de la filière de la presse au prisme du numérique, aux besoins des internautes et relativement rentables.Le terrain investi est celui de l’Afrique de l’ouest francophone, il présente des spécificités parfois éloignées des références reconnues dans le domaine. Notre corpus est composé de trois portails, Seneweb.com (Sénégal), Lefasonet.net (Burkina Faso) et Abidjan.net (Côte d’Ivoire). / Information diffusion on the internet is now provided by a multiplicity of actors with, on the peak audiences, portals, also designated under the vague concept of Infomediaries. Their emergence is part of a re-configuration movement of the media space, driven by the Information Technology and Communication (ICT) (Internet and Web 2.0, specifically).The research presented here is part of a major observation regarding their success since their appearance while the already established media are struggling to establish viable editorial and economic models on the Internet.We consider that strategies of actors are observable in the heart of the industry under construction of online information and roles are redefined around the production, diffusion and consumption of information enhanced by the phenomenon of convergence.The study plans these strategies of actors as participating in a reconfiguration of the digital media space, dominated by the portals, whose approach relies in a "strategic" way on combining the content and practices certified professional by newspapers publishers, and in "tactical" way, based on marketing methods, in order to propose new models both "editorial and economic" fairly innovative, adapted to changes in the press sector vis-à-vis the digital, to the needs of users and relatively profitableThe area under study is that of Francophone West Africa, it presents some specificities sometimes away from references recognized in the field. Our corpus is composed of three portals, Seneweb.com (Senegal), Lefasonet.net (Burkina Faso) and Abidjan.net (Ivory Coast).

The transformation of a manual paper-based moderation process into an electronic moderation (eModeration) process poses unique challenges. These challenges concern academic processes, people and the user experience of interactive systems. eModeration can improve the user experience of assessment processes while lowering the risk of delaying the process or losing scripts. Despite the benefits associated with optimising assessment procedures, particularly examination procedures, the use of eModeration in South Africa is limited. There are several possible reasons for a lack of eModeration adoption ranging from infrastructure and technical issues through to organisational and human factors. The focus of this study is on the human factors involved in eModeration. Since no User Experience Evaluation Framework for eModeration existed at the time of this research, an in-depth study was conducted based on the experiences of eModeration users in the context of private higher education institutions. The study focused on identifying the most important user experience constructs for the evaluation of an eModerate system within the context of private higher education institutions in South Africa towards proposing a framework. The study was based in the fields of Information Systems and Human-Computer Interaction with eModeration being the application domain. The research used a Design Science Research methodology, which involved the development and testing of a User Experience Evaluation Framework for eModeration. The data generation methods included interviews with deans, eModerators and management, as well as a survey that included responses from both moderators and deans. The research was conducted at Midrand Graduate Institute and evaluated at Monash University. The study makes a validated contribution towards identifying the most important user experience constructs. The identified constructs were utilised in the design and development of the User Experience Evaluation Framework for eModeration, which can be used along with the evaluation criteria tool to evaluate eModerate systems. / Information Science / D.

Notre recherche porte sur le rôle de la crédibilité des offres dans les sites d’e-commerce et les facteurs qui la déterminent. 294 personnes ont été interrogées à exprimer leur perception sur la crédibilité des offres de livres qui ont été composées en variant la source et les signes de leur réputation. La recherche s’inscrit dans une approche quasi-expérimentale qui vise à mesurer l’impact de ces facteurs sur la crédibilité perçue mais aussi à mesurer l’influence de cette dernière sur l’intérêt accordé à l’offre et en conséquence sur l’intention d’achat. Les analyses sont faites en se basant sur un modèle d’équation structurelle (SEM). Les résultats témoignent le rôle pivot de la crédibilité qui médiatise l’effet des signaux de la qualité de l’offre mis sur l’intérêt qu’elle soulève. Cet intérêt, à son tour, convoie l’impact de la crédibilité sur l’intention d’achat. Dans ses relations de cause, la crédibilité reconnaît ces signaux comme ses déterminants importants dont les poids sont de même ampleur et dont les effets sont additifs. Nous trouvons également l’effet significatif de la confiance dans la source ainsi que l’intérêt à la catégorie sur la crédibilité. L’effet de la confiance est positif et remarquable tandis que celui de l’intérêt à la catégorie reste négatif. Enfin, ces résultats nous permettent de conclure l’importance de la crédibilité : soigner la crédibilité de l’offre est le chemin au renforcement de l’intérêt du consommateur ainsi qu’aux performances des ventes. / Our research examines the role of online offers credibility in the customer judgment process and its determinants. 294 persons were requested to express their perception of online book offers credibility which were composed varying on their source and also on a number of reputation signals. This quasi-experiment aims for measuring impact of these factors on offer credibility but also for investigating influence of this one on consumer interest in offer and consequently on his purchase intention. Statistical analysis bases on a SEM model. The most important research finding shows that credibility mediates effects of reputation signals on consumer interest in offer. This element of interest, in turn, executes mediating effect on the causal relationship between credibility and purchase intention. Other results indicate that all the 4 reputation signals are positively associated, at the same amplitude, with perceived offer credibility. These effects are additive, which suggests that multiply these signals must be essential way for improving credibility. We found otherwise that credibility is also affected by consumer trust on the source and his interest manifested on the product category. Effect of trust is positive and remarkable while interest in the category effect is negative, which reveals that people with better knowledge level may be more skeptic than others in judgment process. According to these results, our proposal on the importance of credibility element in e-commerce activities is clear: look after the offer credibility is the nexus of merchants selling performance.

The nature of Internet and Intranet Web applications has changed from a static content-distribution medium into an interactive, dynamic medium, often used to serve multimedia from back-end object-relational databases to Web-enabled clients. Consequently, developers need to make an informed technological choice for developing software that supports a Web-based application for distributing multimedia over networks. This decision is based on several factors. Among the factors are ease of programming, richness of features, scalability, and performance. The research focuses on these key factors when distributing images from an Oracle9i database using Java Servlets, JSP, ASP, and ASP.NET as the server-side development technologies. Prototype applications are developed and tested within each technology: one for single image serving and the other for multiple image serving. A matrix of recommendations is provided to distinguish which technology, or combination of technologies, provides the best performance and development platform for image serving within the studied envirorunent. / KMBT_363 / Adobe Acrobat 9.54 Paper Capture Plug-in

The rise of social media platforms has had a significant impact on the conventional model of gatekeeping. With increased access to information--as well as the ability to contribute to the public discourse--individuals no longer need to rely on the mass media for news. These realities have led to increased conversations surrounding credibility in the digital age. Although not a new concept, fake news has become increasingly common in recent years. The web--particularly social media outlets, like Twitter--have enhanced the spread of misinformation. To combat this, social media platforms have introduced gatekeeping features like verification marks and warning labels. However, questions remain regarding the credibility and effectiveness of these features. Furthermore, little information exists regarding the perceptions of these features. For this study, the researcher examined the perceptions of fake news, verification, and Notices (i.e., warning labels) as they relate to Twitter. These perceptions were captured through a survey that was distributed to Twitter users through MTurk. Results were examined generally as well as in the light of political orientation, ranging from very liberal to very conservative on a 4-point scale. Within the scope and limitations of this study, results indicate that the majority of Twitter users believe that fake news on the platform is a major problem. Additionally, results show that there is no significant difference between the effectiveness of verification and the effectiveness of Notices in slowing the spread of fake news, and neither feature is perceived as strongly credible or effective.
