For My Father and Mother And to

This thesis would not have been completed without the assistance and support of many individuals and organisations. First of all, I am indebted to my principal supervisor Professor Anona Armstrong AM. I wish to express my appreciation to Professor Armstrong, to whom no acknowledgement can give full credit for her valuable guidance and support throughout my doctoral program. My thanks also go to Mr. Don Armstrong AM for his encouragement. For subsequent overall guidance, I am grateful to my co-supervisor Professor Andrew Clarke who, with his rich knowledge on a wide spectrum of regulatory policies, perceived my endeavour to capture a rather neglected legal perspective as being worthy of effort. I thank my wife Miaoli Du for her help, guidance, patience and support throughout my life‟s journey. Your belief in me gave me much comfort during the times of doubt. To my wonderful sons, Rui and Min, I thank you for your patience and understanding especially when dad was “always doing ” his PhD. The picture of the three of you, Miaoli, Rui and Min, in the back of my mind was always a great source of inspiration. I thank my mum, Gaie Zhang, and dad, Yanhuai Li, for supporting me throughout my life. Mama, your benevolence with the community, your stubbornness about life, your eagerness with better education, your encouragement and immense stamina always inspire me. Dad for inspiring me with your work ethic, great manners and persistent stimulation of me to become a healthy and useful person to the world granted me enormous power
