I could not have written this dissertation. My sincere gratitude goes out to Prof. Sebastian Sobecki for offering me the opportunity to pursue my own research interests, and to Dr. Kees Dekker for his guidance and unwavering patience during the writing process. This dissertation has also greatly benefited from the support of my fantastic PhD colleagues at the University of Groningen, who cheered me on until the very final stages of the project. I particularly want to thank Pieter Boonstra and Theo Lap for taking the time to proofread my dissertation in spite of their own busy schedules. I also want to thank Hiske Feenstra, for proofreading nearly everything I wrote during my undergraduate, graduate, and doctoral studies. There is not enough space here to express my gratitude to thank my friends and family individually, but please know that your support has been vital to the process. Since the start of my PhD project the world lost three brave women. This book is dedicated to them.
