    Abstract: Cameleon# is a web data extraction and management tool that provides information aggregation with advanced capabilities that are useful for developing value-added applications and services for electronic business and electronic commerce. To illustrate its features, we use an airfare aggregation example that collects data from eight online sites, including Travelocity, Orbitz, and Expedia. This paper covers the integration of Cameleon# with commercial database management systems, such as MS SQL Server, and XML query languages, such as XQuery.

    Abstract: This empirical paper analyses the importance of information and communications technologies (ICT) in the technological diversification trend among the world’s largest manufacturing firms during the 1980s and 1990s. The objective of the research is twofold: firstly, to emphasise the emerging differences among technologies when companies from different industries patent outside their traditional technological capabilities; secondly, to investigate whether the tendency among large companies from all industries to patent in ICT is distinctive when compared with the tendency to patent in other technologies. We find that technological diversification in large companies has clearly occurred in ICTs. Non-ICT specialist industries increasingly develop, rather than just utilise, the cluster of ICT-related technologies. We conclude that the development of corporate capabilities in the key technologies of the emerging ICT paradigm is more widespread than previously emphasised in the literature. One implication of this observation is that technological diversification and the information revolution may be related phenomena.

    Abstract: In the first part of the paper, existing studies on consumer propensity to buy via the Internet are reviewed in an attempt to shed light on factors explaining consumer willingness to buy food via the Internet. Following a model by Sindhav and Balazs (1999), determinants relating to medium, product, consumer, firm and environment are distinguished. In order to draw the various results together and provide a coherent framework for future research, we then propose a model which combines the Theory of Planned Behaviour and the lifestyle construct. The model can be used to analyse how beliefs affecting consumers intention to buy food via the Internet are formed and changed due to experience with such shopping

    Abstract: IT Risk management is becoming increasingly important for CIOs and their executive counterparts. Educators and managers have materials they can use to discuss specific IT risks in project management, security and other risk-related topics, but they have few resources they can use to have a holistic discussion of enterprise-level IT risk management. This case is intended to address the gap. It describes the IT risks facing a large financial services firm, PFPC, as a result of rapid growth, a large merger and distributed management of the IT function. The firm€ٳ first enterprise-wide CIO, Martin Deere used risk management as a key pillar in a major revamp of the firm's applications and IT capabilities. The case is rich in detail on the firm's IT risks, the new risk management process, including examples of the firm's risk management tools. It also describes early lessons and outcomes in the implementation of risk management capabilities. The case has enough richness and potential controversy to engage students from the undergraduate through executive levels in an informative and interesting discussion of IT risk management.
