Examination of the doctoral level reveals two sorts of information. First, the vast
majority of authors (41) received their PhD in the USA (including several working in
other countries today), nine received them in Anglo-American countries (two in
Canada, Australia, England and New-Zealand, and one in South Africa), two in Israel
and one in Sweden. Four authors did not indicate the country of their doctoral studies.
The authors received their doctorates from 38 universities around the globe, including
Columbia, Harvard, Indiana, Michigan State, Technion, Alberta, Vanderbilt, and
Sussex to name just a few.
