LEADER CHARACTERISTICS AND CORE SELF-EVALUATION iii Acknowledgements First and foremost, I am grateful to Dr. Paul R. Yost, for his mentorship, support, and guidance throughout my time in graduate school. Thank you for letting me explore a topic of personal interest! A hearty thank you to the rest of my committee, Dr. Lynette Bikos and Dr. Robert Lewis, for enthusiastically signing on to the journey and helping me along the way. I really enjoyed working with all three of you! Despite being 2,800 miles away, my family supported me with love and encouragement that was constantly felt across the continent. Mom, Dad, Connie, Erica, Alana, and Grandma Carole: Thank you for supporting me! I know it wasn’t always easy to have the distance and time zones between us. I’m grateful for your visits to Seattle, for being sounding boards, steady rocks, and sources of humor and big laughs when I needed it, for your snail mail cards with words of encouragement, and for your endless patience. I love you all so much. To the family I chose, who moved to Seattle to be with me through graduate school, Jason, Calum, and Kona: I owe you a debt of gratitude for being my faithful companions and a wellspring of love. Jason, you have been the lion’s share of my support network through graduate school and the dissertation process. There are not enough words to convey my gratitude and awe at your strength and resiliency in supporting me through the last six years. Calum and Kona, I appreciate the two of you keeping me company as I worked on this thesis. 1434.
