This book would not be in your hands without the help, guidance, and encouragement of many collaborators, reviewers, and supporters. First, we would like to thank our superb co-authors on the numerous research projects that comprise the book’s foundation. Shuili Du has been with us since the beginning of this research journey, and she has our gratitude and admiration in equal measure. The contributions of our other collaborators have also been valuable. Our research has also benefited immensely from the feedback we have received at innumerable conferences, seminars, and corporate presentations, and from the reviewers and editors of the journals it has appeared in. They helped ensure both the rigor and relevance of our work and
to all these individuals, both academics and practitioners, we are grateful.
