Abstract:
There are a number of people without whom this thesis might not have been written, and to whom I am greatly indebted. My beloved father, who always had confidence in me and offered me encouragement and support in all my endeavors. You are profoundly appreciated for your unflinching commitment to my career pursuit. To my mother, who continues to learn, grow and develop and who has been a source of encouragement and inspiration to me throughout my life, and for nurturing me. And also for the myriad of ways in which, throughout my life, you have actively supported me in my determination to find and realize my potential, and to make this contribution to our world. She taught me to persevere and prepared me to face the challenges with faith and humility.
