Since only a single page is allowed, the persons of most recent memory are highlighted below but by no means or measure represents everyone that deserves thanks. To those persons, too numerous to mention, a heart felt thank you for your efforts in bringing me through the preparation of this work. First and foremost, I thank my advisor Dr. Maya Trotz for giving me the opportunity to work alongside her as we both set forth on a quest to learn the ins and out of academia through teaching together and also by her guiding my work through a myriad of changes and obstacles. I’m forever in your debt Dr. Trotz for the valuable lessons working with you has led me to learn. I also thank all my committee members for their valuable insights and advice and Dr. Sylvia Thomas for being not just my Committee Chairperson but also for being constant source of inspiration to get this work done. For their support and encouragement during the many times of despair and despondency I thank my friends and pillars of strength: Estrella Jackson, Andrew Mellaneo, Dr. Dino Jameson, Dr. Monica Gray, Joniqua Howard, Erlande Omisca, Dr. Helen Muga, Ryan Michael, Larry Abraham, Candice Ramsaran and Myrnelle Sylvester. Thank you all. To my family – the constant source of motivation – thank you for the support through the good and many rough times. Thank you, thank you, thank you. A special thank you to my paternal grandmother, Dora Thomas, who from as far I could remember would tell me every time she saw me “open yuh head, open yuh head”. Well Mama, it has been opened somewhat and without your push I doubt it would have been opened this much. Thank you Mama.
