Symposium Format

Twenty-one presentations, grouped into two sections, will be presented throughout the day. Each speaker will have 15 minutes to present the key points outlined in his or her position paper (see Schedule) and answer any questions. Discussion periods at the end of each section will be used to provide a forum for all participants to pose questions, issues, and points of interest related to the more general issues addressed in the presentations of each Section.

The room has approximately 50 seats together with a computer projector and audio-visual equipment. Slides and overhead projectors are available upon request.

(Note: The presentation times listed in the schedule should be considered conditional on the attendance of the scheduled speakers. If openings in the schedule do occur, presentations will be shifted to earlier time slots and the section discussion periods extended accordingly. Each Section will begin promptly at the times indicated in the schedule.)
