Source: (2002) In, Measuring the Impact of Imprisonment: papers from a roundtable held in London on 9 November 2001. London: International Centre for Prison Studies. Kings College. Pp. 9-15.In this paper, Sue Rex notes that participants in the roundtable brought a wide range of ideas to an open discussion of a number of issues concerning measurement of the impact of imprisonment. She summarizes the issues and discussion according to four key themes: (1) prison should be used as the last resort; (2) specific issues of measurement of imprisonment – such as the necessity and risk in measurements, the question of what should be measured, and measuring the social impact of imprisonment; (3) measuring pubic opinion about imprisonment and alternatives to incarceration; and (4) restorative processes in the prison setting.
