Developing a theory of dynamic risk

ABSTRACT

The Propensities Model is now the dominant applied conceptualization of dynamic risk factors for sexual offending. In this paper five important limitations of this model are identified: it asserts causality but does not explain it; it does not represent human agency; it offers no account of what is involved in the development of propensities; it does not explain stable change in risk; and its account of the operation of static factors is a theoretical leap not supported by the evidence. A more elaborate theoretical framework is developed by integrating ideas from Ward's Good Lives model, Beck's account of schema modes, and Fishbein and Ajzen's Theory of Reasoned Action. This more elaborate framework incorporates the Propensities Model in a way that mitigates its limitations. Implications for research, assessment, and rehabilitation are explored.     

Perceived Social Support among Bullies,Victims, and Bully-Victims

Research indicates that social support plays a protective role among adolescents, but little research has explicitly evaluated its function among youth involved in bullying. Accordingly, this study examined relations among social support, bully/victim status, and psychological distress in a sample of 784 ethnically diverse youth. We assessed differences in perceived social support across bully/victim subtypes, and evaluated peer and maternal social support as protective factors among victims, bullies, and bully-victims. Youth were classified as uninvolved (61.6%), as bullies (14.3%), as victims (12.5%), and as bully-victims (11.6%). Uninvolved youth reported the most peer and maternal social support and the least anxiety/depression. Multivariate analyses revealed that there was a significant interaction between bully/victim groups and peer social support. Specifically, bullies, victims, and bully-victims who reported moderate peer social support also indicated the least anxiety/depression. Results highlight the importance of encouraging youth to develop and effectively use peer support networks as part of bullying intervention programs.

Methanol Detected in a Subdural Hematoma as an Embalming Artifact

Analysis of subdural hematomata has been used to suggest antemortem drug concentrations, with the assumption that materials within the hematoma are less subject to metabolism or degradation during any survival period and postmortem interval. We report the case of an 87‐year‐old woman whose death had not been reported to the coroner's office until postembalming. Autopsy revealed a traumatic brain injury with subdural hematoma causing a mass effect. Testing of the clot indicated a methanol concentration of 51.8 mg%. No additional analyses were detected. These findings suggest that methanol can be present in a postmortem hematoma sample, yet not represent a poisoning. Our findings also suggest that while the interior of hematomata do not necessarily represent completely “protected space” from postmortem diffusion of some blood constituents, such diffusion is not facile, and analysis may still provide useful indications of antemortem drugs present, if not actual concentrations.
