I would like to take a moment to thank the following people whose help made the completion of this thesis possible: Professor Merish, for her helpful suggestions as an engaged and active member of my exam committee. Professor Mitchell, for her constant support of my work, her enlightening ideas, and her steady hand as my advisor. Katie, whose love made the good days great and the bad days better. And finally, my parents. This thesis is dedicated to you. Your constant love and support (and copy-editing skills!) helped me at every step along the way. I choose to live, and not just to survive, because of you
