787 Research culture is far from monolithic. Systems that underpin scholarly communication will migrate to open access by fits and starts as discipline-appropriate options emerge. Meanwhile, experiments will be run, start-ups will flourish or perish, and new communication tools will emerge, because, as the Bethesda Open Access Statement puts it, “an old tradition and a new technology have conve...

It is possible to realize systems supporting cooperative work among users in distance location utilizing recent network technology. Most current computer supported cooperative work (CSCW) systems, however, offer identical display views to all the users through video in order to simulate real world. We use database functions and non-video based communication tools to realize such cooperative wor...

In landscape and urban planning, public participation and interactivity become more and more an issue. Real-time virtual 3D landscapes represent communication tools that allow experts as well as non-experts to use, explore, analyze, and understand landscape information. In our contribution, we describe the architecture and functionality of an interactive, participatory system, Lenné3D, which fa...

Based on the analysis of developer mailing lists of two large-scale open source projects, we argue that, in open source development, processes of knowledge making and sharing exploit the structuring properties of high density, massive interaction for evolutionary purposes. The mailing lists reveal patterns of activity and resource distribution that exhibit ecological features. A high number of ...

This dissertation addresses the combined use of asynchronous and synchronous communication in online computer-supported collaborative learning (CSCL) and the relation with students’ motivation. Previously, online communication had been asynchronous and text-based. Technological developments have recently made it possible to support online learning processes by the use of rich synchronous commun...
