In this paper we present an architecture for an information container that can support complex eGovernment procedures. Based on basic trends and a eGovernment scenario, we apply the research results gained in a project on electronic contracting on this eGovernment scenario. We argue, that eGovernment and eBusiness have structural similarities, that allow us to apply a generic contracting contai...

As an emerging form of enabling technology, Web-based e-Health portals provide patients easier accesses to their healthcare information and services. We design and implement such an e-Health portal which can integrate many backend medical services effectively. A major challenge in designing such a system is to meet critical security requirements, such as the confidentiality of patient data, the...

Trading in electronic markets has been the focus of intense research over the last few years within the areas of Articial Intelligence and Economics. This paper discusses the need for tools to support the design and implementation of electronic market games. Such games simulating real life problems can be used in order to conduct research on mechanism design, markets and strategic behaviour. T...

An e-Transaction is one that executes exactly-once despite failures. This paper describes a distributed protocol that implements the abstraction of e-Transactions in three-tier architectures. Three-tier architectures are typically Internet-oriented architectures, where the end-user interacts with front-end clients (e.g., browsers) that invoke middle-tier application servers (e.g., web servers) ...

the infrastructures used for knowledge management in universities are important. nowadays, higher education institutions must be innovative and have appropriate capacity to change as well as adapting with constantly changing external conditions. therefore, the aim of the present study is to assess the relationship between infrastructures and organizational change capacity (occ) and study their ...

* This work draws extensively on the text of the authors’ research memorandum ‘Toward Institutional Infrastructures for e-Science: the Scope of the Challenge’, released in May 2004 as Oxford Internet Institute Research Report No 2 (hereafter ‘David and Spence’). That publication was derived from the OII’s (September 15, 2003) Final Report on the ‘The Institutional Infrastructure of e-Science: T...

The growing importance of eGoverment is putting pressure on authorities to provide services online and accessible to the citizen. In order to satisfy this necessity, Goverments have to develop high-cost infrastructures in a short period of time and with a diffuse specifications of the objectives and services. In the other hand, there are a large set of initiatives that have been launched for th...

This paper examines how service providers may resolve the trade-off between their personalization efforts and users’ individual privacy concerns. Finding that neither an optimized one-size-fits-all strategy, nor a market-driven specialization of providers or choices between different usage scenarios can solve the problem, we analyze how negotiation techniques can lead to efficient contracts and...

E-scientists want to run their scientific experiments on Distributed Computing Infrastructures (DCI) to be able to access large pools of resources and services. To run experiments on these infrastructures requires specific expertise that e-scientists may not have. Workflows can hide resources and services as a virtualization layer providing a user interface that e-scientists can use. There are ...
