The World Wide Web o ers a great deal of potential in supporting cross-platform cooperative work within locally dispersed working groups. GMD has developed the BSCW System, a Web based groupware tool using the metaphor of shared virtual workspaces. The system is particularly useful { and already used by a large community { for cooperation between researchers in distributed environments. This pa...

Hitchhiker organisms have been known since the earliest days of international travel, but changes in global trade mean that there are more now than ever before. They include a number of serious invasive species and are among the most difficult of quarantine problems to manage. Invasive animals transported as hitchhikers, other than plant pests, fall largely outside the international frameworks ...

This paper proposes the application of a new actor-based extension of Nelson's ZigZag model in humanities, in order to create graph-centric browsing tools for Electronic Editions of multidimensional documents. The combination of the ZigZag model and of cooperation activities of different actor classes allows our model to create innovative, graph-centric browsing perspectives for the user and to...

This -paper d~scribes the architecture of a new large multiprocessor computer system being built at Carnegie-Mellon University. The system allows close cooperation between large numbers of inexpensive processors. All processors share access to a single virtual memory address space. There are no arbitrary limits on the number of processors, amount of memory or communication bandwidth in the syst...

This article presents a brief overview of the meaning of technical cooperation within the United Nations, underscoring the political dimension, i.e. the relationship among States. It also emphasizes the importance of health in this context, using the Americas and Brazil as a benchmark. It illustrates the new paradigm called South-South Cooperation by analyzing an experience in the health field,...

Reciprocity stabilizes cooperation from the level of microbes all the way up to humans interacting in small groups, but does reciprocity also underlie stable cooperation between larger human agglomerations, such as nation states? Famously, evolutionary models show that reciprocity could emerge as a widespread strategy for achieving international cooperation. However, existing studies have only ...

in recent years, virtual communities have been significantly popular and almost all of them are targeted for business profitability. in our study, the profitability of these communities for businesses has been analyzed from a commercial perspective. the study considers virtual community as a business model which can have a great impact on consumer purchase decision process. with respect to refe...

The BSCW system is a Web based groupware tool for asynchronous and synchronous cooperation. We describe the system and the experiences we made with it serving as the backbone of a virtual learning environment for students. The field study took place in summer 1998. It demonstrated the usefulness of the system for students and teachers as well as the need for further research and socio-technical...

This paper describes the architecture of a new large multiprocessor computer system being built at CarnegieMellon University. The system allows close cooperation between large numbers of Inexpensive processors. All processors share access to a single virtual memory address space. There are no arbitrary limits on the number of processors, amount of memory or communication bandwidth in the system...
