Abstract

The aim of this chapter is to appreciate the need for and propose some thoughts on modelling trust–control dynamics for communities that use grid technology. It takes the viewpoint that members within a grid-based community require a trust framework that brings together and takes into account both social and technological approaches to trust. It also emphasises the importance of the simultaneous analysis of trust and control in their co-development. In line with the duality perspective that considers trust and control as independent yet interrelated dimensions, trust is explored in its relation to control. Control is examined as a multi-dimensional phenomenon that includes personal, formal, and social scopes. The analysis of trust appeals to its cognitive and affective dimensions. The model introduced also takes into account the mediating role of psychological ownership in the trust–control dynamics. Specifically, shared psychological ownership is singled out as a new explanatory variable of this dynamic.

Background

Resource Discovery in Virtual Organisations

In many existing VOs, a centralised resource index provides the functionalities to publish and discover resources (Foster, Kesselman, & Tuecke, 2001; Winton, 2005). Using a centralised resource index, a resource can be quickly found and consumed. However, the centralisation of the resource index service raises the issues of scalability caused by the limitation of resources at the index node, such as network bandwidth, CPU capability and storage space. Moreover, the centralisation of the resource index also introduces a single-point-of-failure to the system. The index node centralises all responsibilities for publishing and handling enquiries about resources. Once the resource index fails, all the information about accessible resources will be unavailable.

To reduce the problem of single-point-of-failure, each network node should have the capability to efficiently discover desirable resources by interacting with connected nodes. In SWEVO, each Grid node does not rely on a centralised index to provide resource discovery service, which can support and co-operate with each other in a P2P manner to quickly discover accessible resources to support real-time decision making.
