In this paper, we propose a scalable and fault-tolerant job scheduling framework for grid computing. The proposed framework loosely couples a dynamic job scheduling approach with the hybrid replications approach to schedule jobs efficiently while at the same time providing fault-tolerance. The novelty of the proposed framework is that it uses passive replication approach under high system load and active replication approach under low system loads. The switch between these two replication methods is also done dynamically and transparently.

Autonomic middleware services will play an important role in the management of resources and distributed workloads in emerging distributed computing environments. In this paper, we address the problem of autonomic grid resource scheduling and propose a scheduling infrastructure that is capable of self-management in the face of dynamic behavior inherent to this kind of systems.

The growing computational power requirements of grand challenge applications has promoted the need for merging high throughput computing and grid computing principles to harness computational resources distributed across multiple organisations. This paper identifies the issues in resource management and scheduling in the emerging high throughput grid computing context. We also survey and study the performance of several space-sharing and time-sharing opportunistic scheduling policies that have been developed for high throughput computing.

Recent trends in grid computing development is moving towards a service-oriented architecture. With the momentum gaining for the service-oriented grid computing systems, the issue of deploying support for integrated scheduling and fault-tolerant approaches becomes paramount importance. To this end, we propose a scalable framework that loosely couples the dynamic job scheduling approach with the hybrid replications approach to schedule jobs efficiently while at the same time providing fault-tolerance. The novelty of the proposed framework is that it uses passive replication approach under high system load and active replication approach under low system loads. The switch between these two replication methods is also done dynamically and transparently.

Public relations educators perform an academic and vocational balancing act. Employers demand graduates with developed vocational skills. In the meantime, academics strive to provide students with work skills as well as solid theoretical base, and to also address emerging issues. This paper uses a case study in Geelong, Victoria to examine what Australian regional employers see as desirable attributes in public relations graduates. It then explores how educators address the needs of the employers as well as the needs of the public relations profession.

The enormous human and economic costs associated with occupational stress suggest that initiatives designed to prevent and/or reduce employee stress should be high on the agenda of workplace health promotion (WHP) programmes. Although employee stress is often the target of WHP, reviews of job stress interventions suggest that the common approach to combating job stress is to focus on the individual without due consideration of the direct impacts of working conditions on health as well as the effects of working conditions on employees' ability to adopt and sustain ‘healthy’ behaviours. The purpose of the first part of this paper is to highlight the criticisms of the individual approach to job stress and to examine the evidence for developing strategies that combine both individual and organizational-directed interventions (referred to as the comprehensive approach). There is a risk that WHP practitioners may lose sight of the role that they can play in developing and implementing the comprehensive approach, particularly in countries where occupational health and safety authorities are placing much more emphasis on identifying and addressing organizational sources of job stress. The aim of the second part of this paper is therefore to provide a detailed description of what the comprehensive approach to stress prevention/reduction looks like in practice and to examine the means by which WHP can help develop initiatives that address both the sources and the symptoms of job stress.

With organisational work increasingly performed by the collaboration of distributed groups, an improved understanding is needed of the co-creation of knowledge in emerging virtual structures. We explore the potential of the ubiquitous organisational tool, electronic mail (e-mail), for supporting collaborative knowledge creation in such settings. This research draws on a case study of knowledge creation occurring in e-mail conversations in a large Australian university and adopts a discourse analysis research approach. We describe a model of collaborative knowledge creation derived from the study and identify a preliminary set of key factors for organisational knowledge tools and their use by groups to support collaborative knowledge creation. The paper also provides insights into the role of e-mail in collaborative knowledge creation, not only in facilitating this process, but in shaping a participatory, multi-perspective, team-based approach to knowledge building. Organisational implications arising from this type of knowledge creation are also discussed in the paper.
