I wish to express my appreciation to several colleagues and members of my family for assisting me in completing this thesis.First and foremost, I am infinitely grateful to my husband, Lucio Brunale, my lovely partner.Despite the demands of his own PhD studies, he has sustained me through both the ups and downs of the winding path that led to this thesis with love and generosity of spirit. Furthermore, my son and daughter, Rodrigo and Marina, the roots of my heart, must be sincerely thanked for their ongoing support throughout the entire process of leaving Brazil to start a new life in Australia, and also for their enormous patience, encouragement and understanding in hard times. I am very grateful to my mother, bothers, sisters and nephews for their affection, encouragement and emotional support during the PhD process. I wish to express my deep gratitude to my supervisor, Professor Brad Sherman, for enthusiastically sharing his knowledge with me and for his patient and unstinting support and encouragement throughout my PhD candidature. His knowledge and insight in the field of intellectual property rights have enhanced my thesis immensely. I also acknowledge the contributions of my associate supervisor, Dr. Jennifer Corrin Care, for her advice and assistance during the latter part of my doctoral research. I could not have hoped for more supportive academic supervision.
