The well known explosion of material on prosocial behaviour has come a long way, especially helped by the work of many economists writing in this field. This book is a relatively practical look at the motivation and the problems involved with actually implementing altruistic behaviour. It is intended for students and researchers of this topic, but is also accessible to a wide variety of clinical workers in the healthcare field. In particular, many of the chapters here deal directly with related medical applications. The work is intended as a step in the development and further implementation of what is being learned about why and how people behave altruistically, and how this knowledge can be further put to use for positive clinical applications.
