This paper provides a contemporary example of the disruptive impact of new technology upon industry structure, through investigation into the ongoing viability of retail travel agents in an industry where technology is a key driver of change. The Internet has provided opportunities for major...

Empirical studies on information communication technologies (ICT) typically aggregate the “information” and “communication” components together. We show theoretically and empirically that these have very different effects on the empowerment of employees, and by extension on wage...

Johnson's SB and the logit-logistic are four-parameter distribution models that may be obtained from the standard normal and logistic distributions by a four-parameter transformation. For relatively small data sets, such as diameter at breast height measurements obtained from typical sample...

The research explores ways of making the information systems development process more effective. The thesis documents an original design method. This is the method of incorporating Systems thinking into Information Systems Design (MoIST). The thesis demonstrates that MoIST improves information...

At the beginning of the new century, Information Technologies had become basic and indispensable constituents of the production and preparation processes for all kinds of goods and services and with that are largely influencing both the working and private life of nearly every citizen. This...

EXECUTIVE SUMMARY Undergraduate computing students often produce high quality final-year projects with a software product that has the potential to become commercially viable. It is feasible to identify such projects by enterprise-aware academic staff during the projects' development. The...

Purpose – This paper aims to describe a bilateral symmetric approach to authorization, privacy protection and obligation enforcement in distributed transactions. The authors introduce the concept of the obligation of trust (OoT) protocol as a privacy assurance and authorization mechanism that...

We study variants of the classical stable marriage problem in which the preferences of the men or the women, or both, are derived from a master preference list. This models real-world matching problems in which participants are ranked according to some objective criteria. The master list(s) may...

e-Science and e-Research is about supporting collaborations especially those that cross administrative boundaries. Typically this is achieved through establishing virtual organizations (VOs) where several institutions and individuals wish to contribute resources for their mutual interest, e.g....

We introduce and create a framework for deriving probabilistic models of Information Retrieval. The models are nonparametric models of IR obtained in the language model approach. We derive term-weighting models by measuring the divergence of the actual term distribution from that obtained under...
