I would very much appreciate suggestions for lecturers to approach regarding the two questions I posted as these days I am on a committee for the University of Michigan's Osher Lifelong Learing Institute's Distinguished Lectures Committee, and have found that my first dozen likely candidates at University of Michigan and Michigan State University have not been responding. I have found Dr. Victor Montori, MD, MSc. head of www.patientrevolution.org, and must find others, and especially need lecturers for the change in communication question. Have had little to no response from communication and linguistics departments for that question. Thanks for your kind attention.
