This paper explores cognitively realistic social simulations by deploying the CLARION cognitive architecture in a simple organizational simulation, which involves the interaction of multiple cognitive agents. It argues for an integration of the two separate strands of research: cognitive modeling and social simulation. Such an integration could, on the one hand, enhance the accuracy of social s...

At present the agent paradigm is often used for computational modeling of human behavior in an organizational setting. However, in many developed models only a limited number of (unrelated) organizational aspects are represented. Furthermore, some of these models make little use of a rich theoretical basis developed in social science. This may undermine the practical feasibility of such models....

This paper presents architecture of a collaborative computation environment based on a Grid infrastructure, used as a support for large scientific virtual organizations. The environment consists primarily of a collaborationsupporting user interface, workflow system capable of submission of jobs to the Grid and a Grid-based data management suite. A prototype of such an environment is deployed an...

Received: 26 July 2001 Revised: 21 February 2002 : 10 July 2002 Accepted: 23 August 2002 Abstract Existing competence systems are based on a rationalistic view of competence. While these competence systems might work in job-based organizations, we argue that in more dynamic settings, such as in knowledge-based organizations, the interest-informed actions that capture the emergent competencies o...

This chapter provides a comprehensive basis for understanding the role of trust in knowledge management and systems in organizations. The point of departure is the resource and knowledge-based theories of an enterprise that place knowledge generation as the primary source of wealth and social well-being. The authors show the crucial role of the intangible factors of trust, knowledge and informa...

Each organization exists for the achievement of certain goals. To ensure continued success, the organization should monitor its performance w.r.t. these goals. Performance is often evaluated by estimating performance indicators (PIs). In most existing organization modeling approaches the relation between PIs and goals is implicit. This paper proposes a formal approach for modeling goals based o...

The characteristics of virtual organizations present significant challenges to both distributed data mining methods within a metalearning framework and statistical multi-level models. Using hierarchical models, this paper explicitly address the context heterogeneity existing across the partners of virtual organizations. Two new approaches of context-based distributed data mining are analyzed an...

Waste management is on top of the political agenda globally as a high priority environmental issue, with billions spent on it each year. This paper proposes an approach for the disposal, transportation, recycling and reuse of waste. This approach incorporates the notion of Request Based Virtual Organizations (RBVOs) using a Service Oriented Architecture (SOA) and an ontology that serves the def...

This paper investigates an approach to the use of fractals in architectural design. Two major aspects are discussed. First, the effect of the direction of the line segments on the generated fractal, as well as, the proportions between the generator and the initiator. Secondly, the meanings attached to the lines segments that constitute the fractal are based on some known architectural organizat...
