The international conference "Group Decision and Negotiation (GDN) 2006" aims at bringing together researchers in the areas of Group Decisions, Negotiations, and Negotiation Support Systems. Participants share a common research focus on complex decision problems, which involve multiple...

The importance of broadening community participation in environmental decision-making is widely recognized and lack of participation in this process appears to be a perennial problem. In this context, there have been calls from some academics for the more extensive use of geographic information...

The use of computing to support environmental planning and the development of land use models dates back to the late 1950s. The main thrust of computing applications, which by the early 1980s increasingly included the use of geospatial technologies, is their contribution to better planning and...

The reality of pervasive computing has nearly been realized, if it has not already. Pervasive computing environments promise ubiquitous connectivity, a plethora of information, and seamless computing support. Despite the advances in infrastructure to deliver on Weiser's original vision for...
