Bruhn. A special thank-you goes to my chair, Dr. Mary Cohen, who has supported and assisted me throughout my degree, especially in these final stages of completing my dissertation. I also extend my appreciation to Dr. Don Coffman for his early support of my degree. A special thank-you to my family and friends who have encouraged me throughout this process. I am grateful to Dr. Don Healy, for all of his expertise and support throughout my master's and now Ph.D. degree. A special thank-you to my mother-in-law, Alice Davila, who on countless occasions babysat my two daughters and gave me endless support. I am thankful for my parents, Gary and Judith Dalmasso, who instilled in me the importance of education and of following my dreams. And most of all, I am thankful for my loving husband Dan and our two beautiful daughters Olivia and Adelia for their continued support and willingness for me to spend time away from them so I could achieve my dream.
