We wish to express our appreciation to a number of individuals and entities for providing us with the support and resources that were needed to complete this volume. In particular, Richard Lariviere, former Dean of the College of Lib- eral Arts at the University of Texas at Austin, provided the initial funding and support for the conference that stimulated this volume; we gratefully acknowl- edge his enthusiastic support. Jenny Trinitapoli, now an assistant professor of sociology at the Pennsylvania State University, and Mary De La Garza of the Pop- ulation Research Center at the University of Texas at Austin were instrumental in helping.
