This research-based book is aimed at a wide range of different readerships globally. The book addresses issues of concern for those engaged in debates about the provision of health and social welfare services, the case for collective responsibilities, and the public service ethos more generally. Our focus is particularly upon the role of social and cultural factors in the creation and re- creation of categories of exclusion and inclusion; this finds relevance in a wide range of fields (health sciences, public health, health promotion, occupational therapy, disability studies, social work and social policy). The exploration of implications for policy and practice will make the book of relevance to a practitioner audience as well to academics.
