This paper presents the argument that the use of wikis in a learning environment involves a different way of thinking, learning and knowing than perhaps many practitioners are familiar with. In particular, wikis foster collaborative, egalitarian learning that is designed to foster group interaction instead of just individual performance. Moreover, wiki based learning involves community ideals and challenging modes of interaction for both learners and instructors. The paper begins by summarising the wiki way of learning. It presents a recent study conducted in a classroom environment into how students conceptualised wiki use and uses a case study of a course in mobile workforce technologies to present the basis for a wiki pedagogy. The paper concludes with a discussion on the both the practical and theoretical implications of using wikis in a tertiary education environment.

Purpose: Some 40 years ago Horst Rittel and Melvin Webber published a seminal paper in which they discussed the "wicked problems" facing those who sought to develop solutions to urban planning challenges. Their work recognised that many of the decisions faced by modern management are multi-faceted, and involve a plethora of stakeholders each with a diverse view of what good might look like. The aim of this paper is to consider how the ensuing rich vein of literature relating to the management of such problems might be applied to the logistic challenges of preparing for and responding to a disaster.Design/Methodology/Approach: This paper first examines the issues, dilemmas and decisions facing the humanitarian logistician, as a key component of the preparation and response to a disaster, and concludes that they fall firmly into the ambit of a wicked problem. The paper then reviews the literature that proposes methods for management of such problems, and applies it to the humanitarian logistics field. Findings:The paper concludes that further research is needed to understand the ways in which the three primary approaches of employing authoritative, competitive and collaborative strategies might be best evaluated and employed. In doing so, it recognises that it is essential to engage with the broader disaster management and humanitarian logistic communities in order to help operationalise this theoretical approach.Originality/Value: Whilst the concept of a wicked problem and the associated broad spectrum of literature has developed over a considerable period of time, this has not previously been applied to the challenge of humanitarian logistics which, it is argued, meets all the criteria to be considered as a truly wicked problem. CategorizationThis is a conceptual paper.

Mobile commerce is an emerging trend with the potential to generate new streams of revenue for many established organizations. The paper invokes an exploratory qualitative study into mobile commerce adoption practice in Saudi banks and telecoms with a view to pave the way to the eventual generalization of the finding across Saudi organizations. Organizations in both sectors were approached and interviews carried out with key individuals in order to establish emergent themes believed to be related to the adoption of mobile commerce. The findings revealed that themes related to policy and legal environment, information and communication technology infrastructure, and security, affect organizational mobile commerce adoption in Saudi organizations significantly. Overall 15 adoption themes were identified and organized into three categories namely, environmental/organizational, technological, and miscellaneous factors to form a preliminary conceptual mobile Commerce adoption model.
