I am writing a PhD dissertation that contains two main themes/topics. These topics are fairly different from each other, but they do have (some!) common threads.
Within each theme, I have two rather related sub-themes. Each sub-theme is substantial enough to form a chapter.
How should I structure the dissertation. I was thinking about having two parts, as follows:
Ch.1 - Introduction (discussing general structure & motivation) Part I - Theme 1 - Ch.2 - theme 1 - topic 1 - Ch.3 - theme 1 - topic 2 Part II - Theme 2 - Ch.4 - theme 2 - topic 1 - Ch.5 - theme 2 - topic 2 Ch.6 - Conclusion Appendices and References
The above structure seems a little odd to me, though. Are the purpose of parts to partition the paper completely? That is, should each chapter belong to a part? In the above structure, Ch.1 and Ch. 6 are not in any part.
In addition, would including an introduction and conclusion for each part be appropriate?
