a and b, check. It sounds fascinating, especially the last bit (although I've found that those sorts of arguments are tough to pull off, so I hope it works out).
As for c, one thing that threw me was that you refer to your work first as a "dissertation" and second as a "book". Maybe your intended audience assumes that dissertations are books? Another thing is the phrase "draw a ... connotation" - I understand what you mean, but it doesn't sound like standard usage. I also think I agree with ladybird97 here.
As for the hair, that's where mine is now too (well, depending on my posture). My ponytail tends to alternate between 1.5 inches and 10 inches (approximately), and it definitely gets shorter in the summer. But that mostly has to do with the way I like it to look, and the ways I wear it. My general rule of thumb is to let it grow until I find myself getting frustrated with it - I personally don't view the extra length as being worth the bother.
