nd sexist structures and values of societies - as in left realisms and the
new criminologies of masculinities - the offender as object-of-knowledge ge
nerally emerges as young, impoverished, often black, usually male, and marg
inalised.The offender is portrayed as different, as Other.The article point

of justice. Some emergent theories and practices of justice are mentioned,
and it is argued that theories and institutions of justice need to bring to
