Ed., MPhil) A THESIS SUBMITTED FOR THE DEGREE OF DOCTOR OF PHILOSOPHY DEPARTMENT OF ENGLISH LANGUAGE AND LITERATURE NATIONAL UNIVERSITY OF SINGAPORE 2005 ACKNOWLEDGEMENT I am very grateful to many people from diverse backgrounds for their invaluable contributions in several forms towards the completion of this work. First, I owe a great debt of gratitude to Dr. Sunita Anne Abraham, who has been helpful as principal supervisor and inspiring with her invaluable guidance, able supervision, and unflagging interest in my research. I would also like to express my profound gratitude to Associate Professor Christopher Stroud and Dr. Peter Tan Kok Wan, the other members of my thesis committee, for their encouragement, which has made the completion of this work possible. I have greatly benefited from discussions with Professor Desmond Allison, Associate Professor Paul Matsuda, Professor Ken Hyland, Professor Tony Silva, Dr. Paul Bruthiaux, Dr Lawe-Davies, and Ms. Juno Price during the initial stages of the work, while shaping the research proposal. Their suggestions were very helpful in guiding me to current literature in the area of study. I am indebted to the National University of Singapore (NUS) for offering me both admission and a research scholarship to enable me to conduct the study. I am thankful to my mates in the Department of English Language and Literature – Ms. Anggara Mah and Ms. Jennifer Tan – and fellow students from other departments in NUS – Mr. Edward Bannerman-Wood, Mr. Ajibade Aibinu, and Mr. Issahaq Umar – for providing different forms of assistance (rating of textual data, analysis of the data, word processing, and statistical assistance) and crucial social support during the different stages of the research and throughout the entire period of my candidature. ii I also extend my deep appreciation to the University of Cape Coast (UCC) for granting me study leave. Special thanks go to Associate Professor Jane Naana Opoku- Agyemang, then Head of the English Department, who provided access to materials for my preliminary analysis. To Associate Professor L. K. Owusu-Ansah and Associate Professor E. K Yankson, I say thanks for putting at my disposal relevant PhD theses. My appreciation also goes to the heads of department, deans, lecturers, and second-year students at UCC who participated in this research; and, Mr. Philip Gborsong and Mr. Nartey, my Research Assistants, as well as the departmental administrative clerks who helped in the data collection. Finally, I am indebted greatly to my wife, Joy, for her perseverance, understanding, and constant support. My three lovely daughters – Josephine, Marilyn, and Priscilla – have had to spend all these years without me, when they needed me most. I hope they realize what their patience, perseverance, and understanding has done for me. I would also like to express my heartfelt gratitude to my mother and siblings for their constant encouragement and continual prayer. Ultimately, I thank God for strength and comfort during times of difficulty and for allowing me to accomplish my goal. iii TABLE OF CONTENTS CHAPTER PAGE Acknowledgement…………………………………………………………….... ii
