Lance Holbert, Ph.D. Professor in charge of thesis on behalf of the Advisory Committee Approved: __________________________________________________________ Elizabeth Perse, Ph.D. Chair of the Department of Communication Approved: __________________________________________________________ Tom Apple, Ph.D. Dean of the College of Arts and Sciences Approved: __________________________________________________________ Daniel Rich, Ph.D. Provost ACKNOWLEDGMENTS Words cannot express how grateful I am to Dr. Lance Holbert, whose contributions to this project are outweighed only by his commitment to providing an outstanding education to all of his students. Dr. Holbert has graciously shared with me his ability to think theoretically and empirically, and beyond demonstrating what it takes to be a good researcher, has shown me by example what it takes to be an exceptional teacher. For having faith in my abilities and constantly encouraging me, and for being the best mentor I could have asked for, I thank Dr. Holbert endlessly. I would like to express how much I appreciate the insight and guidance of my committee members, Drs. Elizabeth Perse and Jennifer Lambe. I also sincerely thank the faculty and staff of the Department of Communication at the University of Delaware, for providing a superior program of study and for making graduate school an enlightening and enjoyable experience. Thank you to Kurt Braddock, Andy High, Arianna Horry, Kate Mullen, Kevin Tressler, and Jackie Winslow, for being the best cohort ever. I extend heartfelt gratitude to my parents, David and Juanita Veselenak, for their love and support, and especially, for the countless sacrifices they have made to allow me to reach this point. iii
