HiTrust: building cross-organizational trust relationship based on a hybrid negotiation tree

Small-world phenomena have been observed in existing peer-to-peer (P2P) networks which has proved useful in the design of P2P file-sharing systems. Most studies of constructing small world behaviours on P2P are based on the concept of clustering peer nodes into groups, communities, or clusters. However, managing additional multilayer topology increases maintenance overhead, especially in highly dynamic environments. In this paper, we present Social-like P2P systems (Social-P2Ps) for object discovery by self-managing P2P topology with human tactics in social networks. In Social-P2Ps, queries are routed intelligently even with limited cached knowledge and node connections. Unlike community-based P2P file-sharing systems, we do not intend to create and maintain peer groups or communities consciously. In contrast, each node connects to other peer nodes with the same interests spontaneously by the result of daily searches

Perspectives of Integrated “Next Industrial Revolution” Clusters in Poland and Siberia

Rozdział z: Functioning of the Local Production Systems in Central and Eastern European Countries and Siberia. Case Studies and Comparative Studies, ed. Mariusz E. Sokołowicz.The paper presents the mapping of potential next industrial revolution clusters in Poland and Siberia. Deindustrialization of the cities and struggles with its consequences are one of the fundamental economic problems in current global economy. Some hope to find an answer to that problem is associated with the idea of next industrial revolution and reindustrialization initiatives. In the paper, projects aimed at developing next industrial revolution clusters are analyzed. The objective of the research was to examine new industrial revolution paradigm as a platform for establishing university-based trans-border industry clusters in Poland and Siberia47 and to raise awareness of next industry revolution initiatives.Monograph financed under a contract of execution of the international scientific project within 7th Framework Programme of the European Union, co-financed by Polish Ministry of Science and Higher Education (title: “Functioning of the Local Production Systems in the Conditions of Economic Crisis (Comparative Analysis and Benchmarking for the EU and Beyond”)).

Collaboration and the Ecology of Democracy

This Kettering Foundation report explores the features and implications of citizen-driven, multi-party collaboration. Kettering has called the spaces and opportunities where this type of collaboration takes place the "political wetlands." Kemmis and McKinney embrace this ecological metaphor, seeing the emergence of democracy as similar to the self-organizing phenomena that arise in the natural realm. As democracy has evolved and matured over the millennia, it has become more bureaucratic and structured. Toward the end of the 20th century, citizens' desire for a more authentically engaged and constructive kind of involvement has produced new, less structured forms of deliberative and collaborative democracy.Several case studies of collaboration revolving around natural resources and governing public land are provided. In Idaho, for example, the Henry's Fork Watershed Council brings together competing interests -- farmers, ranchers, anglers, outfitters, guides, and environmentalists -- and provides a forum where they can address challenges that arise along the watershed. For nearly two decades, this group of people, who often stand on opposite sides of the political divide, has resolved problems by tapping into the collective intelligence of its members.The authors suggest that such place-based, collaborative initiatives may evolve into new forms of democratic governance

The OMII Software – Demonstrations and Comparisons between two different deployments for Client-Server Distributed Systems

This paper describes the key elements of the OMII software and the scenarios which OMII software can be deployed to achieve distributed computing in the UK e-Science Community, where two different deployments for Client-Server distributed systems are demonstrated. Scenarios and experiments for each deployment have been described, with its advantages and disadvantages compared and analyzed. We conclude that our first deployment is more relevant for system administrators or developers, and the second deployment is more suitable for users’ perspective which they can send and check job status for hundred job submissions

Secure, performance-oriented data management for nanoCMOS electronics

The EPSRC pilot project Meeting the Design Challenges of nanoCMOS Electronics (nanoCMOS) is focused upon delivering a production level e-Infrastructure to meet the challenges facing the semiconductor industry in dealing with the next generation of ‘atomic-scale’ transistor devices. This scale means that previous assumptions on the uniformity of transistor devices in electronics circuit and systems design are no longer valid, and the industry as a whole must deal with variability throughout the design process. Infrastructures to tackle this problem must provide seamless access to very large HPC resources for computationally expensive simulation of statistic ensembles of microscopically varying physical devices, and manage the many hundreds of thousands of files and meta-data associated with these simulations. A key challenge in undertaking this is in protecting the intellectual property associated with the data, simulations and design process as a whole. In this paper we present the nanoCMOS infrastructure and outline an evaluation undertaken on the Storage Resource Broker (SRB) and the Andrew File System (AFS) considering in particular the extent that they meet the performance and security requirements of the nanoCMOS domain. We also describe how metadata management is supported and linked to simulations and results in a scalable and secure manner

Analysis of recreational land using Skylab data

The author has identified the following significant results. S192 data collected on 5 August 1973 were processed by computer to produce a classification map of a part of the Gratiot-Saginaw State Game Area in south central Michigan. A 10-category map was prepared of an area consisting of diverse terrain types, including forests, wetlands, brush, and herbaceous vegetation. An accuracy check indicated that 54% of the pixels were correctly recognized. When these ten scene classes were consolidated to a 5-category map, the accuracy increased to 72%. S190 A, S190 B, and S192 data can be used for regional surveys of existing and potential recreation sites, for delineation of open space, and for preliminary evaluation of geographically extensive sites

Key skills by design: Adapting a central Web resource to departmental contexts

Web‐based delivery of support materials for students has proved to be a popular way of helping small teams to implement key skills policies within universities. The development of ‘key’ or ‘transferable’ skills is now encouraged throughout education, but resources (both in terms of staffing and budget) tend to be limited. It is difficult for key skills teams to see learners face to face, and not feasible to print or distribute large amounts of paper‐based material. Web‐based delivery presents a means of overcoming these problems but it can result in generic study skills material simply being published online without due consideration of the needs of different groups of learners within different subject disciplines. Therefore, although a centralized Website for skills provision can overcome logistical problems, it may be perceived as irrelevant or unusable by the student population. This paper presents a model for Web‐based delivery of support for key skills which incorporates two separate approaches to the design of these resources. The model was implemented as part of a wider key skills pilot project at University College London, over a period of one year. It includes a ‘core’ Website, containing information and resources for staff and students. These can also be accessed via customized, departmental key skills homepages. This paper presents the basis for the design choices made in preparing these materials, and the evaluation of some of the pilot departments using them. It then draws some wider conclusions about the effectiveness of this design for supporting skills development
