Learning is a socially embedded design process. But most of today's hypermedia systems fail to properly support both the design-related and the social aspects of learning. Authoring and web-publishing systems aim ...

We present a strategy, called recursive prismatic time skewing, that increase temporal reuse at all memory hierarchy levels, thus improving the performance of scientific codes that use iterative methods. Prismatic tim...

Tools for computersupported collaborative work offer many advantages for their users. Some developments in this field have included agent-based approaches for CSCW. Many challenges face the development and application of distributed, agent-based solutions for CSCW. A concern often overlooked is the acceptability and social impact of these technologies. In particular, the management of the privacy of collaborators is a paramount issue that must be accommodated. Included and related to the privacy of user information and interactions are assurances of integrity, certification, validation, ownership, non-repudiation, and authentication of individuals and software systems operating on disparate computers and operating systems, communicating over heterogeneous networks. We outline our early work on an approach for accountable privacy that may be applied to distributed computersupportedcooperativework (CSCW) environments. Particular challenges for the issue of privacy associated with the CSCW application scenario are discussed.

This paper introduces a further study towards telematic systems, especially in relation to their importance for telework. With respect to this issue, the paper considers the role of telematic applications in support of telework. In particular, it investigates telework support brokerage systems, which turn out to be crucial for the spread of telework among broad social circles. As a possible infrastructure for such systems, the paper considers telecenters. It is shown how such a brokerage system could be practically implemented, providing ideas about the system architecture. Finally, attention is paid also to some social issues, discussing the great importance of modern information and communication technologies (including telework as one of the best examples of successful mass application of these technologies with great benefits for society) for the human prosperity of tomorrow.

This paper describes the design, setup and evaluation of an educational project in computer architecture studies. Its design through the educational-telematic framework DELFOS, proposed by the authors' research group, aims to employ computersupported collaborative learning in computer engineering studies. Its main objective is to integrate lectures, simple assignments and laboratory work through projects and case studies in computer architecture design and evaluation. Experimental studies were carried out during two academic years with very encouraging results. At least three student groups in each session dealt with one out of 5 distinct case studies. Students assumed the roles of consulting firm and computer manufacturer, who try to give an answer to a specific customer/market sector. cooperative learning was carried out through synchronous guided discussions within the class in key dates, asynchronous document sharing and discussions, as well as collaborative edition of the final project report. Analysis of the experimental work was performed on both ethnographic data and computer transcriptions, while current studies deal with student interactions with social network analysis methods.

In this paper, we describe our experience with the longterm, widespread use of CoWeb, an asynchronous collaborative tool that is mostly used to complement existing face-to-face groups (such as classes). The CoWeb is an open-ended tool that does not enforce or explicitly support specific roles or usage, yet several well-defined uses and roles have emerged over time. In our design methodology, we recognize these roles and refine our collaboration environment to better support them.

This paper presents analyses of calls to a bank's telephone call centre decumenting the way calls are opened, closed, and how financial services are actioned. Throughout, how the social interaction between caller and operator is interleaved with the human-computer interaction between operator and the bank's accounts database is attended to. We show participants varying in their orientation to each other and to providing and receiving database information, and how these matters are influenced by the recent introduction of more 'active', 'intelligent' technology. Implications for design of interactive technology in such settings and for the study of organisations in CSCW are offered.

In the past, most collaboration support systems have focused on either automating fixed work processes or simply supporting communication in ad-hoc processes. This results in systems that are usually inflexible and difficult to change or that provide no specific support to help users decide what to do next. This paper describes a new kind of tool that bridges the gap between these two approaches by flexibly supporting processes at many points along the spectrum: from highly specified to highly unspecified. The development of this approach was strongly based on social science theory about collaborative work.
