Acknowledgments

We would like to thank each of the contributing authors for taking the time to write their chapters. Their insights and practical experiences have made the book much richer.

Thanks also to Nick Wallwork and Ms. Gemma Rosey of John Wiley for getting the book into shape and guiding us through the publishing process.

Finally, we are indebted to our families, who have been a great source of encouragement and support in every step of the way.
