This book is the product of research that was possible because of two Australian Research Council (ARC) grants. The first was a Discovery Project (awarded together with an Australian Research Fellowship) which I attained with Professor Kathleen Daly and Dr Jackie Huggins, both of whom I owe a great deal of gratitude. They were both willing to become Chief Investigators on the grant application, despite the fact that they were already over-burdened with other work. They saw value in the research and agreed to participate in the project as needed. Without their guidance, mentorship, friendship and support, I may never have achieved what I was able to achieve. The second grant was an ARC Future Fellowship grant, which allowed me to further analyse the data from the first grant and to produce this book. Without both these grants, this book probably wouldn’t exist.
