G. W. Pasdirtz: I use my blogs to make informal comments on policy topics related to my research interests in the World-System, computer simulation of the US Health Care System, the US Economy, the US Stock Market, and the US Financial System. I am retired from the University of Wisconsin -- Madison. I have taught Statistics and Computer Science and also served on the UW's HIPAA Task Force and the Bioterrorism Task Force. I have also been a member of my local planning commission, a jazz guitarist and a golfer, so some of that may find its way into the blogs.
