This research attempts to fill this gap by conceptualising trust across three dimensions: competence, integrity, and benevolence; testing hypotheses as to the effect of these facets of trust on knowledge sharing by surveying a virtual community of systems thinking practitioners within a global organisation that engages in information systems integration and IT outsourcing. The results indicate that all three dimensions of trust are positively related to knowledge sharing behaviour. The findings suggest that the dimensions of trust buttress each other. However, we highlight that further research is required to better understand the dynamics of trust within online communities. Nonetheless, this research challenges system developers to integrate trust-building functionality to enable history and transparency of data which provides confidence in future behaviours. Knowledge management practitioners also have to encourage competence, integrity and benevolence in employees, who are potential members of on-line communities of practice. http://hdl.handle.net/10397/1453 Title: A Two-Tier Approach to Elicit Enterprise Portal User Requirements<br/><br/>Authors: Tsui, Eric; Yu, Calvin; Lau, Sau-mui Adela<br/><br/>Abstract: Organizations are increasingly turning to enterprise portals to support knowledge work. Portal deployment can be intradepartmental across several business units in one organization or even inter-organizational. Currently in the industry, most of these portals are purchased solutions (e.g., collaboration and smart enterprise suites) and many of these purchasing and selection decisions are primarily driven by the interest of a small group of stakeholders with strong influence from IT vendors. The true requirements for the portal as well as the strategy for its medium- to long-term phased deployment are, in general, poorly addressed. This, together with other reasons, has lead to many failures or to a low adoption rate of the enterprise portal by staff at various levels of an organization. Common problems that hinder portal adoption include lack of an overall governance model, mis-alignment with business processes, poor or non-existent content management (process,tools, and governance), and technical problems associated with the development and configuration of portlets. This article focuses on one critical issue that directly influences the success of an enterprise portal deployment, namely the correct elicitation of user requirements (which in turn lead to the chosen portal’s features and to the style of the portal interface). Taking into consideration the advancement and landscape of commercial portal vendors in the market, this article discusses a bottom-up approach to the identification of high-level drivers for portal usages for its users. http://hdl.handle.net/10397/1452 Title: Application of Web 2.0 Technology for Clinical Training<br/><br/>Authors: Lau, Sau-mui Adela; Tsui, Eric<br/><br/>Abstract: In clinical training, students plan, implement and evaluate their learning activities by themselves. They apply theories and concepts in a real clinical environment and learn through social interaction and reflective thinking to experience, conceptualize, apply and create new knowledge to solve clinical problems. Since students are sent to different clinical locations for training and are mentored on a one-to-one basis, it is difficult for students to share their knowledge, make enquiries or interact with their peers and mentors for social and reflective learning. Web 2.0 provides a collaborative and social interactiveplatform that allows learners to exchange, share, acquire, codify, distribute, and disseminate knowledge. Its functions and features are able to construct a virtual and distributed environment for learners to gather, filter and update the knowledge over different Internet sources. This chapter thus aims to discuss the functions and features of Web 2.0 technology and its applications to clinical training.
