Untangling the antecedents of initial trust in Web-based health information: The roles of argument quality, source expertise, and user perceptions of information quality and risk

As the Internet develops as a medium for disseminating health-related information, research on Web-based health information consumption grows increasingly important to academics and practitioners. Building on the current research in this area, our study proposes a model of initial trust formation in Web-based health information, rooted in the elaboration likelihood model (ELM) and Toulmins model of argumentation. The proposed model theorizes trust as a function of perceived information quality and perceived risk, which are in turn determined by the structural quality of the message (argument quality) and the expertise of the message source (source expertise). Testing of the research model was accomplished via a field experiment involving 300 online users who had searched for health information on the Web. Overall, the results largely support the proposed model, explaining substantial variance in trust and highlighting the important but distinct roles that argument quality, source expertise, and user perceptions of information quality and risk play in determining an individuals decision to trust health information online.

When users are IT experts too: the effects of joint IT competence and partnership on satisfaction with enterprise-level systems implementation

Enterprise-level information systems (IS) are fundamental to businesses. Unfortunately, implementing these large-scale systems is a complex and risky endeavor. As a result, these initiatives must tap the expertise and active involvement of both the IS department and the enterprises functional areas. Past studies focusing on IS implementation teams consistently identify the IS department as the source of technical expertise and leadership, while functional department team members are typically relegated to the role of business experts. However, unlike the past, many business professionals are knowledgeable about information technology (IT) and are increasingly capable of contributing to IS implementations from a technical perspective as well as a business perspective. This study examines how IT competence held by both the IS department and the user department stakeholders contributes to user satisfaction with the enterprise-level system implementation. Specifically, this research introduces a theoretically grounded construct, joint IT competence, which emerges when the IS department and user department stakeholders integrate their individually held IT competences. The studys results empirically demonstrate that joint IT competence is a key driver of user satisfaction in enterprise-level IS implementations. Although not as significant as joint IT competence, results show that partner-based leadership between the IS department and user stakeholders also influences user satisfaction with IS implementations.

A heuristic-systematic model of end-user information processing when encountering IS exceptions

IS exception management often relies on end-users for success. A key aspect of end-user management of IS exceptions is sufficient information processing before responding. However, end-users process information dynamically across different judgmental contexts and sometimes favor effort reduction over accuracy maximization. With todays IS tightly meshed with underlying organizational business processes, inappropriate end-user responses pose organizational risks. We therefore developed a theory-based research model which was designed to uncover the motivational mechanisms needed to provide effective information processing in this context. Empirical testing using 318 experienced users of Microsoft Excel supported our model.

The Roles of Psychological Climate, Information Management Capabilities, and IT Support on Knowledge-Sharing: An MOA Perspective

Leveraging the motivation-opportunity-ability (MOA) theoretical framework and past research on psychological climate, this study analyzes three antecedent factors driving an individual’s knowledge-sharing (KS) within organizations: knowledge-sharing psychological climate as motivation, information management capability as ability, and organizational information technology support as opportunity. An empirical examination reveals that a motivating psychological climate has a primary impact on KS behavior, and the impact of perceived information management capability on sharing is mediated by the psychological climate. Perceived organizational use of information technology to support knowledge work bears strong influence on information management capabilities but not on sharing, suggesting that investment in IT does have indirect payoffs. The study is the first to position the opportunity→ability→motivation causal network in an individual’s KS behavior. The findings suggest that managers need to consider the pre-requisite roles of IT-enabled opportunities and workers’ information management abilities when building an all-important motivating climate to share.

Leveraging the it Competence of Non-Is Workers: Social Exchange and the Good Corporate Citizen

Organizational IT competence is fundamental to achieving strategic value through technology investments. Importantly, as business users continually gain experience with enterprise systems and a new generation of tech-savvy workers enters the labour force, IT competence is increasingly distributed beyond the IS department. Despite its strategic potential however, IT competence residing within the functional areas of the firm is essentially untapped until it is volunteered by functional area knowledge workers. Addressing the changing landscape of IT competence across the enterprise, the current study examines factors that drive business professionals to volunteer their IT competences to the firm. This research introduces the concept of IT competence volunteering, which is conceptualized as a form of organizational citizenship behaviour that is not explicitly contracted by the firm and may not be directly rewarded. Guided by social exchange theory, a multi-foci model is introduced that positions IT competence as well as workplace exchange relationships as antecedents of IT competence volunteering intention. Overall, the studys results empirically demonstrate the important impacts that user-IS department exchange and perceived organizational support have on the business professionals intention to volunteer his/her IT competence to the firm.

User disposition and extent of Web utilization: A trait hierarchy approach

As it evolves, the World Wide Web (the Web) increasingly reveals the potential to enhance new aspects of our daily lives. While some take full advantage of the Webs diverse and cutting edge offerings, others choose to limit the extent of their utilization to a small subset of the Webs available functions. Recognizing this variation, a growing body of research investigates the drivers of usage behavior on the Web. Individual differences, namely broad personality and IT-specific traits, are highlighted within this stream as important predictors of Web use. Although substantial progress has been made, an important issue still facing trait research in this area is the absence of a theory-grounded basis for inter-relating broad personality and IT-specific traits. As a result, the accumulation of extant trait research is characterized by a disjointed assortment of trait constructs lacking clear theoretical linkages with one another. Additionally, while numerous studies have investigated isolated Web usage behaviors, an important outcome that remains under-investigated is the extent of an individuals utilization of the Web overall. Addressing these issues, the current study leverages the hierarchical view of traits to develop a theory-grounded, integrative model of broad personality and IT-specific traits. After developing the hierarchical model, the integrated network of traits is positioned as a direct antecedent of Web utilization and empirically tested via a two-stage field survey of 230 Web users. The results corroborate most of the hypotheses, providing support for the hierarchical view and extending the knowledge base on Web-user behavior. Overall, this study unifies disjointed personality and IT-specific trait constructs and offers theoretical guidance for future studies, introducing a much-needed ground for cumulative tradition within this stream.

Time‐User Preference and Technology Acceptance: Measure Development of Computer Polychronicity

Past research recognizes the important influence of individual beliefs on technology acceptance and use. This line of research has also identified a variety of factors that drive the formation of these beliefs. One category of variables that has received less attention in this research stream consists of individual preferences, in particular time-use preferences. In the current study we address the gap in the technology acceptance literature by introducing and empirically testing a new construct labeled computer polychronicity, which captures individuals’ time-use preferences regarding information technology. A new measure of computer polychronicity is developed and subsequently tested using partial least squares estimation. Computer polychronicity is then theorized as a key driver of perceived usefulness, linking computer anxiety and computer playfulness to perceived usefulness. Overall, the results of model testing support the notion that preferences play an important role in the formation of technology-related beliefs.

Cross-cultural influences on e-value creation in supply chains

Purpose – This paper seeks to report the results of an empirical study examining the influence of cross-cultural differences on the value creation process from e-business systems in the supply chain. Design/methodology/approach – A questionnaire was sent out to senior managers in companies operating in two culturally distinct national cultures. The effects of cross-cultural differences were examined by testing for between-group differences in the structural model using the multi-group partial least squares (PLS) statistical approach. Findings – Consistent with the resource-based view (RBV), contingency “fit” theory, and prior research, this study demonstrates that the value creation process from e-business systems is significantly enhanced in companies operating in national cultures that emphasize cooperation and interdependence, and promote group-level interests over individual interests. Originality/value – The mechanisms through which performance improvement is achieved from e-business systems are stil...
