Formation of virtual organizations in grids: a game-theoretic approach

Thomas E. Carroll
Abstract Applications require the composition of resources to execute in a grid computing environment. The grid service providers (GSPs), the owners of the computational resources, must form virtual organizations (VOs) to be able to provide the composite resource. We consider grids as self-organizing systems composed of autonomous, self-interested GSPs that will organize themselves into VOs with every GSP having the objective of maximizing its profit. Using game theory, we formulate the resource composition among GSPs as a coalition formation problem and propose a framework to model and solve it. Using this framework, we propose a resource management system that supports the VO formation among GSPs in a grid computing system. Copyright © 2008 John Wiley & Sons, Ltd. [source]

Features of the Java Commodity Grid Kit

Gregor von Laszewski
Abstract In this paper we report on the features of the Java Commodity Grid Kit (Java CoG Kit). The Java CoG Kit provides middleware for accessing Grid functionality from the Java framework. Java CoG Kit middleware is general enough to design a variety of advanced Grid applications with quite different user requirements. Access to the Grid is established via Globus Toolkit protocols, allowing the Java CoG Kit to also communicate with the services distributed as part of the C Globus Toolkit reference implementation. Thus, the Java CoG Kit provides Grid developers with the ability to utilize the Grid, as well as numerous additional libraries and frameworks developed by the Java community to enable network, Internet, enterprise and peer-to-peer computing. A variety of projects have successfully used the client libraries of the Java CoG Kit to access Grids driven by the C Globus Toolkit software. In this paper we also report on the efforts to develop serverside Java CoG Kit components. As part of this research we have implemented a prototype pure Java resource management system that enables one to run Grid jobs on platforms on which a Java virtual machine is supported, including Windows NT machines.

Smart Labels for Waste and Resource Management

An Integrated Assessment
Summary This article explores the potential of RFID (radio frequency identification device) for improving the current waste and resource management system in Switzerland. It presents the following three possible options for utilizing RFID tags to support waste management processes: "at source automation" (using a "smart" trash can), "end of pipe I" (combination of the current system with an additional separation of recyclables before incineration), and "end of pipe II" (replacement of the current recycling infrastructure by sorting at the incineration plant). These options tackle the waste and resource management chain during different processes (i.e., waste generation, waste separation, and treatment). Based on an MFA (material flow analysis), we performed a multicriteria assessment of these options with experts from the waste management sector. The assessment of ten experts in the waste management field regarding the proposed options for batteries and electrical appliances showed that, from an ecological perspective, the implementation of RFID in waste management would be desirable and would lead to an improvement in the current recycling rate in Switzerland for the goods studied. From an economic perspective, new investments would be required in the range of 1 to 5 times the maintenance costs of the current separate collection system. From a social perspective, the utilization of RFID tags in the waste management process was ambiguous. In particular, the end of pipe II option would, on the one hand, significantly improve convenience for consumers. On the other hand, experts see privacy and, what is more, social responsibility as being under threat. The experts considered the ecological and social aspects to be more relevant than the economic ones, preferring the end of pipe I option over the other options and the status quo. [source]

Decolonising, Multiplicities and Mining in the Eastern Goldfields, Western Australia

Leah M. Gibbs
In this ,postcolonial' era, peoples and places around the globe continue to face ongoing colonisation. Indigenous peoples in particular experience colonisation in numerous forms. Despite recent attempts to ,decolonise' indigenous spaces, hegemonic systems of production, governance and thinking often perpetuate colonial structures and relationships, resulting in further entrenched colonisation or ,deep colonising' (Rose, 1999). The interface between indigenous communities and the mining industry provides fertile ground for the tensions emerging between decolonising and deep colonising. Gold mining operations at Placer Dome's Granny Smith mine in the Eastern Goldfields of Western Australia present a valuable case study for examining this tension. Changes taking place at the mine site are decolonising in intent, though outcomes may be deep colonising in effect. Recent discussions among cultural geographers over meanings of place, Ollman's (1993) notion of vantage point and a broadly postcolonial literature inform consideration of this tension. Acknowledgment and incorporation of multiple vantage points into new resource management systems allows current hegemonic approaches to be rethought, and provides insights for the shift towards genuinely decolonising processes.

The perplexing role of learner control in e-learning: will learning and transfer benefit or suffer?

Benjamin P. Granger
The appeal of e-learning is not surprising given its many proposed advantages (e.g. flexibility, responsiveness to trainees' individual needs, potential cost-effectiveness). However, as pointed out by RuŽl et al., academic research in support of the proposed advantages of electronic human resource management systems is scarce. Although this is generally the case for technologically mediated training, the extant research on e-learning actually questions many of its proposed advantages. In this conceptual piece we (1) establish the link between e-learning and learner control, (2) summarize the advantages and disadvantages of learner-controlled e-learning, (3) briefly present the results of a recent study conducted in our research lab that addresses the disadvantages of learner-controlled e-learning for the training of complex material, and (4) discuss research-based recommendations for the application of learner-controlled e-learning in organizational settings.

The Phenomenon of Collective Action: Modeling Institutions as Structures of Care

Raul Lejano
This essay develops a theory of how institutions can work through the web of social relationships that exist in a place rather than through formal, bureaucratic lines of authority. In contrast to models that characterize institutions as organizational structures, roles, and patterns of exchange, this model depicts institutions as constituted primarily through the active working and reworking of relationships. Rather than adopt the network literature's focus on the overall pattern of relationships and exchanges carried out between policy actors, the author focuses directly on the nature of the relationships themselves and portrays the institution as the playing out of these relationships, employing Carol Gilligan's notion of care. The model of care is used to analyze the evolution, unraveling, and restoration of resource management systems on the Turtle Islands in Southeast Asia. The model provides lessons for institution building, especially for community-centered governance. [source]
