Volume 25, Number 4 Fourth Quarter 2005 RISKnewsletter Published by the SOCIETY for RISK ANALYSIS Specialty Group Leaders Provide Reports from the Field Adam M. Finkel As the new chair of the Society for Risk Analysis (SRA) Specialty Groups Committee, I asked the chair of each group to take a stab at an end-of-the-year “report from the field”—to give SRA members unable to keep up with developments outside their own area of special interest a brief sense of what might be new and exciting in other specialties. I appreciate the thoughtful submissions and hope they will spur interest in related sessions that the groups are sponsoring at the 2005 SRA Annual Meeting in Orlando, 4-7 December.
