The construction industry and its resources: a research agenda

The desirable coverage of the journal is considered including the need to focus on research which can lead to positive action. Criteria for establishing the desirability of research projects are proposed and these are then applied first, to four broad issues and, secondly, to the inputs and other requirements for a well functioning industry. Some conclusions are drawn as to the research most likely to enable action to be taken to improve the industry. It is found that certain other difficulties can sometimes be dealt with by experimentation with actual projects or, where there is consensus on desirable action, by bringing pressure to bear on those able to initiate change.

Second language listening strategy research: methodological challenges and perspectives

This paper explores methodological issues related to research into second language listening strategies. We argue that a number of central questions regarding research methodology in this line of enquiry are underexamined, and we engage in the discussion of three key methodological questions: (1) To what extent is a verbal report a valid and reliable way of eliciting information about strategies? (2) Should we control for learners' level of linguistic knowledge when examining their listening strategy use? and (3) What are the problems surrounding the analysis of data gained through verbal reports? We discuss each of these three methodological issues within the framework of a research project investigating listening strategies deployed by learners of French in secondary schools in England. Implications from these findings for future research are discussed.

Semantic organization to enhance active learning based on distributed multimedia educational resources

In order to organize distributed educational resources efficiently, to provide active learners an integrated, extendible and cohesive interface to share the dynamically growing multimedia learning materials on the Internet, this paper proposes a generic resource organization model with semantic structures to improve expressiveness, scalability and cohesiveness. We developed an active learning system with semantic support for learners to access and navigate through efficient and flexible manner. We learning resources in an efficient and flexible manner. We provide facilities for instructors to manipulate the structured educational resources via a convenient visual interface. We also developed a resource discovering and gathering engine based on complex semantic associations for several specific topics.

A flexible monitoring and notification system for distributed resources

Resource monitoring in distributed systems is required to understand the 'health' of the overall system and to help identify particular problems, such as dysfunctional hardware, a faulty, system or application software. Desirable characteristics for monitoring systems are the ability to connect to any number of different types of monitoring agents and to provide different views of the system, based on a client's particular preferences. This paper outlines and discusses the ongoing activities within the GridRM wide-area resource-monitoring project.

Swarms of computational resources and swarms of tasks for building reliable systems

Space applications demand the need for building reliable systems. Autonomic computing defines such reliable systems as self-managing systems. The work reported in this paper combines agent based and swarm robotic approaches leading to swarm-array computing, a novel technique to achieve autonomy for distributed parallel computing systems. Two swarm-array computing approaches based on swarms of computational resources and swarms of tasks are explored. FPGA is considered as the computing system. The feasibility of the two proposed approaches that binds the computing system and the task together is simulated on the SeSAm multi-agent simulator.
