Iona, Welcome to the forum, your dissertation topic is very interesting. You've mentioned your Master's thesis, I would be very interested in reading that, do you have it on a PDF file or other online source that would be available for viewing? And, if you wouldn't mind, how about sending me in a PM your real name and contact information so I can verify it. As you said, it is difficult to just assume that someone writing on a forum is really who they say they are. Thanks.
