The contributions of many people made this book possible. The support and contributions of the editorial staff of Kris Ellis-Levy, Sarah Holle, and Bernard Ollila made a tremendous difference.

The production and manufacturing teams at Pearson Education also deserve special mention. Project Managers Meghan DeMaio and Karalyn Holland handled the details, scheduling, and management of this project with grace and aplomb. Many thanks also to Judy Leale. Without their assistance, many visuals and text items would never have made their way into this book.

Our experience in working with everyone at Pearson Education has been superb. Everyone at Pearson approached this book with commitment and enthusiasm. We were partners with the Pearson staff and feel that we are part of a high-performance team. We appreciate the commitment they displayed and would like to thank them for the experience. The authors would like to acknowledge the following contributors, for writing assessment questions for the new MyLab activities: Erikson Daniel Conkling, Ivy Tech Community College - Northeast, Gordon Schmidt, Indiana University-Purdue University Fort Wayne.

We would also like to thank the many colleagues who have reviewed both the past editions as well as the current edition and have offered valuable feedback.
