I'm asked by all of my doctoral students at some point during their writing to give them good dissertation examples.  I'm not complaining, it's a fair question, to help them improve the quality of their dissertation.  Over the last few years, I have asked permission of students to use their dissertation as an example.  

Here are a few examples.  Use them as you will  -- just remember that your dissertation is unique - just as the following dissertations are unique. Is one dissertation better for you to look at?  The best analogy is: Which is better vanilla or chocolate ice cream?  It depends on your preference in ice cream!
