Wells ACKNOWLEDGMENTS I would like to thank Dr. Mihelcic for giving me the opportunity to participate in the Master’s International program and for providing needed guidance during my time on-campus and abroad. I would also like to thank committee members Dr. Arias and Dr. Whiteford for the support and knowledge you have shared with me throughout this experience. Thank you to Dr. Wells, Kevin Orner, Christine Prouty, and my wonderful MI group for your helpful thoughts which were essential in shaping my work. I would also like to thank the supportive in-country staff and volunteers of Peace Corps Cambodia as well as Ung Prahors, Sok Chantary, and Chantha Oeurng for all the help you provided me throughout my service. A special thank you goes to my counterpart and friend Lach Phors who worked tirelessly by my side for the two years in Cambodia. I could not have done it without you. To my family, thank you as always. My mom especially, you were my inspiration for making the journey back to your home country.

Finally, I would also like to take this opportunity to remember my closest friend, Chelsea Brown. You were the first on board to support this dream of mine. I will always have so much appreciation for you. And to her family, who have now become my family over the course of this experience.
