When I did my Diploma in Binary University College, it was compulsory for Diploma student to do research paper in their third year.
I did my researh paper surrounding Public Relations. The title of my research paper was:
THE STUDY OF PUBLIC RELATIONS AND CUSTOMER SATISFACTION IN THE WIRELESS TELECOMMUNICATION INDUSTRY IN MALAYSIA
You can download the copy of my research paper as I believe it might give you some clue or idea if you ever come across requirement to do research paper and by any chance it is related to public relations.
