Acknowledgements

No intellectual journey is taken alone and I have had the great good fortune to be have been accompanied by some wonderful people. These people have made the journey less lonely because of their willingness to engage in conversations that have challenged my views and who have provided me with a great deal of very good advice and much needed assistance. Marion Bannister and Sue Clancy travelled the road with me, not only giving me the courage to undertake this journey but also the benefit of their wisdom about the task of writing. Marion Bannister provided research and editorial assistance and I am forever grateful to her.

Various colleagues read chapters of the text as it was in preparation and I thank them from taking the time. Finally, my family is acknowledged with great love and thanks for giving me the time to undertake this work.
