I would like to express my most sincere and warmest appreciation to my supervisors, Associate Professor Guillermo Aranda-Mena and Adjunct Professor Peter Edwards, for their guidance, insight and expertise. I am particularly indebted to Adjunct Professor Peter Edwards for his ongoing support and for pushing me that bit harder when it needed to happen. I am grateful for the time and commitment of all participants involved in this research; both whom agreed to take part in interviews and the focus group, and those who offered valuable contributions off the record. Thank you. I would also like to thank my wife Caroline, and my children Emma and Hugo, for believing in me during this journey. Your love and patience has meant so much.
