While I cannot answer your question myself, I may be able to refer you
to someone who can.  Dr. Stephen Bitgood is a very prolific member of
the Visitor Studies Association and the Center for Social Design.  He
has been most helpful to me in the past and will no doubt be able to
answer your questions.  I do not have an email address but his postal
address is as follows:
 
                        Dr. Stephen Bitgood
                        Vistior Studies Association
                        P.O. Box 1111
                        Jacksonville, AL 36265
                        (205)782-5640  FAX: 205-782-5640
 
Hope that this helps somewhat.
