Acknowledgments from Ben Rosenzweig

I would like to thank my coauthor Elena Silvestrova for being a wonderful and knowledgeable colleague to work with. I would also like to thank Douglas Scherer for giving me the opportunity to work on this book as well as for providing constant support and assistance through the entire writing process. I am indebted to Carol Brennan for her technical edits; she saved me from errors in every chapter. I would like to thank Kathryn Castelle, who did a great job reading over the manuscript and making suggestions. Finally, I would like to thank the many friends and family, especially Edward Clarin and Edward Knopping, for helping me through the long process of putting the whole book together, which included many late nights and weekends.
