| To my family and friends ii ACKNOWLEDGEMENTS I would like to thank many people who were instrumental in helping me finish my Ph.D. My advisors John Hayes and Igor Markov provided me with excellent ideas to pur-sue, offered endless advice and comments on every publication we worked on together, and pushed me to do a great deal of solid research over the years. Maintaining one’s sanity is also a key part of surviving graduate school, and my friends at Michigan played a major role in that regard. In no particular order, I deeply thank David | |||||||||||||||
