In preparing this dissertation, I acknowledge my indebtedness to the following: My supervisor Dr Katrin Voltmer for her invaluable guidance; to Ms Angharad Thomas without whose help it would have been very difficult to obtain data for the empirical study; to the respondents for bearing with me during the interview; to the staff of the Edward Boyle Library and the Brotherton Library for retrieving the relevant books for me; to my family members for their constant encouragement; to my friends for their support; and to numerous other people for helping me in their own ways from time to time.
