Dear Alan, Good question. I feel the answer is not so straightforward - it's part of the broader picture of career development through doctoral education. Phil Agre's classic resource on developing a career via doctoral education provides lots of info and analyses in this context see , "Networking on the Network" - http://dlis.gseis.ucla.edu/people/pagre/network.html There was also a recent set of articles in New Scientist that goes over some of this ground and might be useful, If you are interest is in engineering design, in the UK the professional doctoratye, the DEng, is a much higher status than a PhD and for that it doesn't matter where your first degree was undertaken. Best regards, Terry ===
