* DISSERTATION DEFINED:
Longer academic documents come with different names:
Theses involve propositions or positions that are substantiated by argument or empirical research that could be gathered by qualitative, quantitative, or mixed methods;
Treatises are systematic, written expositions and arguments involving methodical discussion about the principles involved and conclusions reached about a topic;
Research projects require applying qualitative, quantitative, or mixed methods to gather empirical information about a topic; and
Dissertations are the extended, written treatment of a topic. The latter is the most general category, because theses, treatises, and research projects are all dissertations: Extended, systematic discussions about topics.
