Several authors have expressed concern regarding the use of youth psychopathy assessments in determinations of risk for general and violent offending. The Psychopathy Checklist: Youth Version (PCL:YV) was completed with 182 male adolescent offenders in this prospective study (average 14.5 month follow-up) of general and violent recidivism. Both a two-factor and three-factor model of the PCL:YV significantly predicted general and violent recidivism at a predictive accuracy ranging from 68 to 63%. However, regression analyses indicated these associations were explained primarily by behavioral psychopathic symptoms, rather than interpersonal or affective traits. Implications for the use of psychopathy assessments for risk during adolescence are discussed.

of the Los Alamos Scientific Laboratory has just been received which makes the same analysis as does Professor Halliwell (the misleading extension of a valid thermodynamic rule in cases where it is not valid). To further illustrate the fact that series of related E°'s fall on lines which intersect rather than have a common slope they supply a graph which strikingly demonstrates the relationship between the potentials of the plutonium oxidation states.

Five models of sentencing were assessed with respect to their impact on the decisions of young offenders to recidivate. The five sentencing models tested were fairness, deterrence, chronic offender lifestyle, special needs, and procedural rights. A sample of 400 incarcerated young offenders from the Vancouver, British Columbia, metropolitan area were asked questions regarding their attitudes toward these sentencing models and their intentions to recidivate after serving a period of incarceration. Principal components analyses suggested that although these models do not function independently, two composite models do shed some light on the issues that young offenders consider when contemplating their decisions and intentions to recidivate. Despite the ability of these models to predict half of the explained variance in young offenders’ decisions regarding recidivism, a majority of the sample appeared to not be affected exclusively by cost-benefit analysis, punishment, or reintegrative motivations. The authors conclude that without additional variables and even higher predictive validity, it is premature for policy makers to focus on any single model of sentencing in constructing juvenile justice laws.
