Abstract: In present paper a novel approach to on-line payment is presented that tackles some issues of digital cash that have, in the author's opinion, contributed to the fact that despite the availability of the technology for more than a decade, it has not achieved even a fraction of the anticipated popularity. The basic assumptions and requirements for such a system are revisited, clear (economic) objectives are formulated and cryptographic techniques to achieve them are proposed.

Title: Using Agent Technology to Overcome Project Failure in Distributed Organizations
Authors: Holly Parsons - Hann and Kecheng Liu
Abstract: As organisations become more global and interest groups more widely distributed reaching a consensus among stakeholders when conducting a global spanning project becomes increasingly harder to achieve. Many software projects have failed because their requirements were poorly negotiated among stakeholders and this problem must be solved if project failure is to decrease. Although many stakeholder negotiation methods have been suggested, validated and employed in projects across the globe, project success rates are still very low, suggesting that there is still work to be done in the distributed organisational domain to increase the probability of project success. This paper will highlight the current project management problems in distributed organisations and suggest a new agent based method of solving them.
Title: A Normative Approach to Capture and Analyze Quality of Service Requirements of Distributed Multimedia Systems
Authors: Mangtang Chan and Kecheng Liu
Abstract: With the availability of powerful hardware, it is now possible to manipulate multimedia data with normal desk top computers. Further enhanced by the World Wide Web, the Internet serves as a platform for truly distributed multimedia systems (DMS). Non-functional requirements play an important role in the analysis and design of DMS and one of them is quality of service (QoS). This paper proposed a methodology to integrate QoS modeling under a semiotic framework which can then be used to analysis both the functional and non-functional requirements of DMS. The semiotic framework is agentoriented. QoS characteristics and requirement for agents would first be defined, a normative approach would then be used for static model checking, admission test as well as run-time QoS monitoring and policing. The methodology is demonstrated by examples of some common DMS and related work in QoS modeling and specification will also be reviewed.
Title: An Empirical Study into Governance Requirements for Autonomic E-Health Clinical Care Path Systems
Authors: Mr. Philip Miseldine and Prof. Azzelarabe Taleb-Bendiab
Abstract: Information technology has been widely recognized as a key building block to the Government modernization agenda for the NHS, and a vital component to assisting continuous improvement in clinical practice, patient safety and standard of care. Medicine is far from a static field, and this is especially true for research into the prevention and treatment of breast cancer, which is thankfully ever changing and advancing towards more comprehensive care and therapy for the condition. With such a fluid and fluctuating set of requirements, software that aids in the delivery and prognosis of therapy faces real challenges in its design so that it can adapt successfully as and when required to new requirements in the field. This paper will discuss the challenges that designers of such software must solve, and highlights the issues facing current state-of-the-art solutions in the domain of breast cancer prognosis. The paper then introduces the notion of system self-governance to produce a rigid yet highly dynamic system that is evaluated through a case study involving several leading UK cancer hospitals. The paper concludes with analysis of how the principals introduced in the paper can be applied to the wider domain of eHealthcare.
Title: A Practical Approach to Goal Modelling for Time-Constrained Projects
Authors: Kenneth Boness, Marc Bartsch, Stephen Cook and Rachel Harrison
Abstract: Goal modelling is a well known rigorous method for analysing problem rationale and developing requirements. Under the pressures typical of time-constrained projects its benefits are not accessible. This is because of the effort and time needed to create the graph and because reading the results can be difficult owing to the effects of crosscutting concerns. Here we introduce an adaptation of KAOS to meet the needs of rapid turn around and clarity. The main aim is to help the stakeholders gain an insight into the larger issues that might be overlooked if they make a premature start into implementation. The method emphasises the use of obstacles, accepts under-refined goals and has new methods for managing crosscutting concerns and strategic decision making. It is expected to be of value to agile as well as traditional processes.
Title: An Isomorphic Architecture for Enterprise Information Systems Integration
Authors: Mingxin Gan, Lily Sun and Botang Han
Abstract: Enterprise information systems often face difficulties in linking various components and external systems. Interoperability among collaborating participants is hard to tackle in both business and IT domains. These call for effective architectural solutions that coordinate powerful technologies with business applications to enable seamless inter-organizational integration. The inter-organizational integration of information systems needs to be considered from an architectural point of view on issues around business, organization and information technology. In this paper, an isomorphic architecture for systems integration (IASI) is proposed with a focus on supply chain management systems. This architecture allows integrating the business agility and IT infrastructure by consolidating processes between these two domains, and facilitates business changes with simultaneous evolution of the IT infrastructure.
Title: Modelling the role of e-learning in developing collaborative skills
Authors: David King, Sharon Cox and Richard Midgley
Abstract: This paper presents a model to assist in planning the use of e learning to support the teaching and learning of transferable skills needed to support collaboration. The model is derived from the practical experience of tutors teaching technical undergraduates in a UK university. The findings suggest a three stage model taking a student through participation and collaborative engagement in the teaching material, learning by reflection upon its content in groups, and finally an innovative method of supporting their comprehension of the skills being taught.
Title: Towards Purposeful Collaboration in E-Business:  A Case of Industry and Academia
Authors: John Perkins and Sharon Cox
Abstract: Information and Communication Technology (ICT) helps to remove barriers and improve mechanisms that support collaboration in e-business. This paper proposes a model of purposeful collaboration analysis that helps identify the extent to which ICT supports collaboration. It is argued that the ICT components of e-business are necessary to support collaboration but in themselves are often insufficient as enablers of collaboration. The model encourages the examination of issues left unsupported by ICT and allows more focused consideration of further initiatives that might be applied to improve purposefulness of the collaboration task. The case of a retail manufacturer in a long term e-business collaborative exercise with an academic institution is used to illustrate the model. Concepts from the social practice literature are identified that might contribute to a hybrid approach to addressing the gap resulting between generic technology and situated business applications.
