This volume both problematizes and renders visible conceptions and norms regarding male behaviour and masculinities, showing how these affect the criminological field through providing a theoretically sound and clear gender perspective to this field of research. With sections based around the following three themes: negotiations of masculinity in institutional settings; vulnerable masculinities; and risk-taking and masculinities, this volume will be of interest to scholars of criminology, sociology, social work and gender studies, as well as policy-makers, and law enforcement professionals.
