The authors wish to thank Christina Norman for the conscientious detail with which she assisted us on various administrative tasks during the beginning phases of this book project. The authors also wish to thank Sharon Panulla and Anna Tobias at Springer for their helpfulness and responsiveness throughout the process. Thanks also to Steven Rogelberg (University of North Carolina at Charlotte) for putting us in touch with Sharon. Finally, Doug Maynard would like to thank Amanda Maynard for her continued support and insights, beginning with the lunch date in graduate school in 1997 that initially inspired my interest in the topic.
