A systematic analysis of stakeholders could enrich the systems thinking and modelling methodology. Among the five phases of the systems thinking and modelling framework, namely, problem structuring, causal loop modelling, dynamic modelling, scenario planning & modelling, and implementation & organisational learning, the importance of stakeholder analysis in the problem structuring and scenario ...

In this paper we examine the requirements of large scale cooperative applications, namely those alternating multi-part synchronous work sessions with variable periods of asynchronous interactions and disconnected work. We discuss the topological organization of the large scale cooperative space and the materialization of an integrated generic platform to support those requirements. Our approach...

This research proposes and empirically tests a model of post adoption process improvements realized through use of partners’ Internet-based e-business applications. We identify constructs proposed within adoption and post-adoption use theoretical models as well as presented in existing inter-organizational systems research. Our analysis reveals purely organization-based factors; namely, informa...

Quality of service (QoS) differentiation within the optical infrastructure is under constant development due to the direct impact of the ever-rising demand for time-critical and multimedia applications in the Internet. In this paper, we propose an efficient prioritized hybrid model based on two eminent approaches namely, resource-reservation and extra offset-time based QoS that have already bee...

We present a new approach for routing in multi-tier heterogeneous wireless mobile ad hoc networks. This protocol, namely multi-virtual backbone protocol (MVP), naturally addresses key challenges arising from multi-tier wireless networks such as the coverage asymmetry and node heterogeneity. It also supports various QoS needs by constructing and maintaining QoS-specific virtual backbone infrastr...

In this paper, we give a brief introduction of the HTRDP Chinese Information Retrieval Evaluation, which is sponsored by HTRDP (High Technology Research and Development Program of China, namely 863 Program). The web data collection, query design, evaluation metrics, and the evaluation procedures will presents in detail. Like TREC, NTCIR and CLEF, its purpose is to provide the infrastructure nec...

In the last eighteen months, a consensus has emerged from researchers in various disciplines that a vital piece of research infrastructure is lacking in Australia, namely, a substantial collection of computerised language data. A result of this consensus is an initiative aimed at the establishment of an Australian National Corpus. The progress of this initiative is presented in this paper, alon...

Autonomic computing is gradually becoming accepted as a viable approach to achieving self-management in systems and networks, with the goal of lessening the impact of the complexity crisis on the computing industry. The authors propose the integration of high level selforganisation features into an Application Directed Adaptive Framework (ADAF), an autonomic-oriented software development proces...

The choice of suitable high-level communication primitives for wide area network programming languages remains an open problem. This paper is driven by the practical consideration of providing an efficient and secure communication infrastructure for mobile agent systems. This has led us to formalise the Lime coordination middleware and propose a simplified model, which we call CoreLime, that ad...

The turning point has been sealed with World Development Report 1997 by the World Bank, where, following the approach of the new institutional economy, government effectiveness and other dimensions of good governance are recognised as premises for better development outcomes: “the state is essential for putting in place the appropriate institutional foundations for markets”2. The attention is t...
