importance of education and the necessity of keeping one's mind sharp and always open to knowledge and experience. To my wife, Cavell Walcott, words are insufficient to express the sacrifice, patience, and support you have provided during the many years and life stages, including the birth of our first son, in the pursuit of this academic accomplishment. Without your support, this journey could not have been successful nor would I have had the strength to endure it. Liam, one day you may remove the dust from this manuscript and read its contents, and I hope you learn that perseverance, scholarship, service, and empowerment will overcome all of life's obstacles. Finally, thank you to the community that stands alongside me-for without you there would be no me.
