The Detroit Hearings are an effort at developing an additional method of collaboration between the city and the university. The aim is to develop an environment of collaboration around major areas of concern out of which a wide range of collaborative efforts could develop. It is both a complement and supplement to the traditional methods of consultations, grants, contracts, and joint institutions. The Hearings method is based on a collaborative-consortial arrangement, where the partners have a broad general concern and where neither the specific needs nor capability of responding are clearly defined. The Hearings were one of four elements funded through a National Science Foundation grant given jointly to the City of Detroit, the University of Michigan, and Wayne State University, for the purpose of developing consortial means of collaboration in dealing with city problems and making available scientific knowledge and personnel for that purpose. This report describes how the hearings were organized, what happened at them, and what is coming out of that experience. A brief description is also included of collaborative projects resulting from the hearings that will need funding support. (LBH)
