It has been ten years since I last spoke to this group; long enough for you to have forgotten what I said at that time. As an expatriate from the profession I am delighted to have this opportunity to meet with you again. I am especially pleased that you have chosen to meet here and on behalf of Dean E. J. Kersting I extend a very sincere welcome and best wishes for a successful program.
