This book is for anyone interested in research involving humans, such as researchers, potential participants, ethics committees and institutional review boards, university educators and students, and policy makers. It analyses the limitations of respect for autonomy that lead to under-research of vulnerable groups, and explores new ethical approaches. 'The strength of this volume is its timeliness and humanistic core, as manifested in the deep concern for the good of humankind, which must serve, the authors agree, as the goal of human research. This book is recommended for scholars and practitioners interested in bioethics, legal studies, and research methodologies and regulation.' M. Uebel, Choice
