I would like to take this opportunity to express my immense gratitude to the many wonderful people who have given their invaluable support and assistance during the preparation of this work.

First and foremost, I am profoundly indebted to my supervisor and mentor, A/ Prof Khurshid Alam who has provided unalloyed support and guide for me during my study at Murdoch University. His enthusiasm and encouragement are instrumental to the success of this work.

I am deeply grateful to Ms. Sandra Crewes for painstakingly reviewing and editing this work, even at a very short notice.

I owe a special debt of gratitude to my darling wife, Abimbola Odunyemi and my daughters, Adebola Odunyemi and Adebusola Odunyemi for being always there for me through thick and thin.

I would like to thank the Australian Government, the Department of Foreign Affair and Trade that provided me the scholarship that allowed me to obtain this lifetime opportunity to acquire first-class learning experience in Australia.

Finally, my profound gratitude goes to God Almighty who is the ultimate source of wisdom and knowledge.
