The following people deserve special mention for their contribution to the creation of this book:

To each of the authors for so generously sharing their experiences and insights in the chapters, and for their patience as we dealt with earthquakes, illness and political uncertainty to finally get to publication.

Dr Ronnie Davey for assisting us above and beyond the call of duty with the final proofing and editing.

Laura Dixon for her imagination and creativity in the design and desktop publishing.
Our sincere thanks to each of you,

Vince and Derek
