A project of this magnitude would not be possible without the assistance of many individuals. I would like to offer my thanks to Lynn Taylor and Megan Peckman of Bergin & Garvey. Both Lynn and Megan provided valuable editorial advice and a genuine understanding of this subject. To Tyler Collins, my graduate assistant, who spent countless hours in the library and on-line locating references and resources and who constructed both appendices, Figure 1.1, and Table 2.1, I would also like to offer my sincere thank you. And, to Bridget McKeon and Dorian Tinaro, two additional graduate assistants, I owe my thanks for preparation of camera-ready artwork. To Crystal Thacker, I owe a thank you for hours spent creating the index. Finally, to the many parents who shared their experiences and “stories” with me, I would like to offer a humble thank you. We have a unique bond and a compelling mission.
