who are special gifts in my life.iv ACKNOWLEDGMENTS Completing this dissertation is the fulfillment of a long-time personal dream and a goal I was not sure I would have the opportunity to accomplish. Many people offered support and played important roles in my life before and during-and hopefully afterthis process. Thank you to my family, friends, colleagues, and mentors from past and present who have given me so much to help me get here and to shape me not just into a better doctoral student but a better person.First thanks go to my wife, Gina, who made many sacrifices to go down this path with me. You make my life shine with meaning, and through you in so many ways God has made me a better person, husband, father than I believed possible. Thank you for sharing life with me and for being family, someone to whom and through whom I will always belong. Thank you for raising Noah and Alvin together with me. And I'm so thankful for Noah, how you give me reasons to laugh and smile and to work harder and better and more efficiently; in so many ways, having you during this time made life-and even my dissertation-better and more meaningful.I would also like to thank our family for all of their support.

Finally, I do not have sufficient words of gratitude for this, but I will try. Tim and Kim Landrum, you both have given so, so much kindness, support, wisdom, and friendship to me and my family. You've just embraced us, and you're family. I don't even know how to describe it, but I think you understand.
