These are the latest batch of recent doctoral dissertations harvested from the issues 79-02 A and B of Dissertation Abstracts related to your subject area. Now that I have retired I have limited my dissertation harvesting to the last several years’ coverage-still plenty of items that may interest to you.
You will find some duplicate citations-the ProQuest database is including over 30% duplicate titles, sometimes in multiple months. I try and catch these duplicates but I am sure you will find that I missed some.
