As explained in the Preface, this book draws on an AHRC Speculative Research

Project, and hence follows a structure to some extent dictated by the investiga-

tion. As such it is strongly research-based, but also – importantly – is specula-

tive in its approach, specifically seen as a scoping exercise, and thus does not

claim to be a final definitive treatment of the subject but aims to add to our

existing knowledge and propose a conceptual framework for subsequent activ-

ity (research and practice) which is seen as rather weak to date in this subject

area. While seen primarily as inductive in that it seeks to identify key concepts

and an appropriate analytical basis derived from these concepts for further

application, it is inevitably based on an existing set of concepts and issues

largely drawn from the experience of the main investigators and book editors.
