I thank all the professors at the University of Maryland, College Park, with whom I interacted. On some level, each and every one of them is somewhere in this.
I owe my greatest debt to my advisor, Professor Don C. Piper, for all his ideas, assistance, friendship, and what must have been incredible forbearance in the face of my incessant worrying. He would have every right to get an unlisted phone number after this experience. But for some reason, lie keeps on providing me with a support system--thanks.
I also thank Professors Richard P. Claude, Earllean McCarrick, Larman Wilson, and David Segal, for serving on my committee. Their time and efforts on my behalf are greatly appreciated. I also extend my gratitude to James R. Ice, Liz Murphy, Dina K. Rubin, and Kathleen Taylor at the Greenwood Publishing Group, for all their work on shepherding this project through to completion. By now, probably no one's time and effort on this manuscript has exceeded that of Sharon Furman--it's a shame that this herculean word- processing chore had to come at the expense of her sanity.
I would finally like to thank my wife, Sharon A. Sykora. It takes plenty of patience to put up with me in normal times. It took all the patience of the gods to put up with me while writing this. Her editing and suggestions made this work better, Her love makes me better.
