The writing of this book would not have been achieved without the help of many people, who in different ways supported me and made themselves and their resources available to me during my doctorate research and the writing of the PhD thesis which form the basis for this book.My profound gratitude goes to Professor Dr Peter Scholliers, my PhD academic supervisor, who despite my shortcomings and challenges never gave up on me. I sincerely thank him for taking out time to read the manuscript again, make comments, advice and support me throughout this process.I thank the members of the Nigerian community who agreed to be interviewed, provided needed information and supported me during my PhD research. Although I cannot mention you all, I appreciate your support. I couldn't have done this without your help especially Chief and
