Finally, thank you to Timothy Caspar and Ellen Johnson, who, in addition to being my loving parents, are singularly intelligent people who put up with their daughter's foray into the social sciences for four years and contributed to every draft of this work. I didn't forget you, Hannah-thanks for telling me I could do it. You're up now! I look forward to reading your thesis in four years-I'm sure it'll make me proud to be your sister. This thesis is dedicated to the memory of Keith Johnson, who made it possible for me to come to Wesleyan in the first place.
