To my wife (Shalom Obi), thank you for being by my side all through this work. To my project students at the undergraduate programme especially Izuchukuwu Alaine, I want to appreciate you all for your immense contributions to this work. To my other colleagues in the YATRAP program thank you for being a big family to me here. I would like to acknowledge and appreciate my parents Mr Christopher and Mrs Ada Emebo, for investing their lives and resources to providing me quality moral, formal education and spiritual upbringing, also for all their parental support, encouragement and belief in me. To my siblings (Uchenna, Ada, and Ifeoma), I thank you all for your believing in me as well and for the prayers rendered ceaselessly in seeing to it that this work is completed.
