This volume features the complete text of the material presented at the Twenty-Fifth Annual Conference of the Cognitive Science Society. As in previous years, the symposium included an interesting mixture of papers on many topics from researchers with diverse backgrounds and different goals, presenting a multifaceted view of cognitive science. This volume includes all papers, posters, and summaries of symposia presented at the leading conference that brings cognitive scientists together. The theme of this year's conference was the social, cultural, and contextual elements of cognition, including topics on collaboration, cultural learning, distributed cognition, and interaction.

Chaired by K Wüthrich (Nobel Laureate in Chemistry, 2002) and co-chaired by B Weckhuysen, this by-invitation-only conference has gathered 39 participants — who are leaders in the field of computational modeling and its applications in Chemistry, Material Sciences and Biology. Highlights of the Conference Proceedings are short, prepared statements by all the participants and the records of lively discussions on the current and future perspectives in the field of computational modeling, from chemistry to materials to biology.

Around the Sacred Fire is a compelling cultural history of intertribal activism centered on the Indian Ecumenical Conference, an influential movement among native people in Canada and the U.S. during the Red Power era. Founded in 1969, the Conference began as an attempt at organizing grassroots spiritual leaders who were concerned about the conflict between tribal and Christian traditions throughout Indian country. By the mid-seventies thousands of people were gathering each summer in the foothills of the Rockies, where they participated in weeklong encampments promoting spiritual revitalization and religious self-determination. Most historical overviews of native affairs in the sixties and seventies emphasize the prominence of the American Indian Movement and the impact of highly publicized confrontations such as the Northwest Coast fish-ins, the Alcatraz occupation, and events at Wounded Knee. The Indian Ecumenical Conference played a central role in stimulating cultural revival among native people, partly because Conference leaders strategized for social change in ways that differed from the militant groups. Drawing on archival records, published accounts, oral histories, and field research, James Treat has written the first comprehensive study of this important but overlooked effort at postcolonial interreligious dialogue.
