What does Dilulio say about the importation model?
It is inadequate as it ignores the role of prison officials and factors relating to the running of prisoners
What is the ACM?
States that poorly managed prisons are more likely to experience the most serious forms of inmate violence, including homicides and rioting
Poor management is characterised by several factors including weak leadership, a thriving culture of informal and unofficial rules, staff who remain distant from inmates, and few opportunities for education
These can act as triggers for aggression and increases the influence of dispositional factors
