Family violence risk assessment: A predictive cross-validation study of the Domestic Violence Screening Instrument-Revised (DVSI-R)

This research was a cross-validation study of the Domestic Violence Screening Instrument-Revised (DVSI-R), using a diverse, statewide sample of 3,569 family violence perpetrators in Connecticut, assessed in February and March of 2007. It analyzed re-arrest data collected during an 18-month period post assessment. Three issues were central, which have been ignored in previous research on family violence risk assessment: (1) analyzing five refined measures of behavioral recidivism, (2) determining whether perpetrator characteristics and types of family and household relationships (beyond just heterosexual intimate partners) moderate the empirical relations between the DVSI-R and the behavioral recidivism measures, and (3) determining whether structured clinical judgment about the imminent risk of future violence to the victim or to others corresponds with recidivism predicted by the DVSI-R total numeric risk scores. The empirical findings showed that the DVSI-R had significant predictive accuracy across all five measures of recidivism. With one exception, these relations did not vary by gender, age, or ethnicity; and again with one exception, no significant evidence was found that types of family or household relationships moderated those empirical relations. In short, the evidence suggested that the DVSI-R was a robust risk assessment instrument, having applicability across different types of perpetrators and different types of family and household relationships. Finally, the empirical findings showed that structured clinical judgment about imminent risk-to-victim and risk-to-others corresponded with the prediction of recidivism by the DVSI-R total numeric risk scores, but the effects of those scores were significantly stronger than the perceived risk-to-victim or the perceived risk-to-others.     

Assessing the Impact of the 1996 Thai Prostitution Law: A Study of Police Arrest Data

The purpose of this paper was to evaluate the impact of the Thai Prevention and Suppression of Prostitution Act of 1996 in ten geographical regions of the country. This paper also addresses law enforcement approaches in controlling prostitution. Data for prostitution arrests from 1995 to 1998 were obtained from official police sources (Statistics of Reported Crimes of Thailand). ARIMA intervention analysis was employed; revealing the arrest rates of prostitutes between pre- and post-enactment of the present Prostitution Act did not differ statistically within the regions except for Region 8 (Phuket). The paper reaches two general conclusions: (1) the 1996 Thai prostitution law did not significantly reduce the arrest rate for prostitution across the country; and (2) further consideration must be given to the idea of decriminalizing prostitution, which might allow for licensure, improving health and living conditions as well as potentially limiting exploitation and impact crimes associated with the prostitution industry.     

Group-Based Dominance and Opposition to Equality Correspond to Different Psychological Motives

Social Dominance Orientation, one of the most popular individual differences measures in the study of generalized prejudice, can be understood as having two components: Opposition to Equality (OEQ) and support for Group-Based Dominance (GBD). We consider these components in terms of system justification theory and social identity theory. We find that each component best explains different kinds of political views, consistent with the theory that they arise from different motivations. OEQ reflects system justification motives. It better predicts attitudes towards redistributive social policy, political conservatism, and a lack of humanitarian compassion for the disadvantaged. GBD reflects social identity motives. It is more associated with hostility toward outgroups and concerns about intergroup competition. GBD and OEQ have different personality and demographic correlates, exhibit distinctive relations with explicit and implicit attitudinal preferences, and differentially predict a variety of policy attitudes. Use of GBD and OEQ as separate constructs enriches the understanding of prejudice, policy attitudes, and political ideology.     

Necessary and Universal Truths about Law?

Prominent analytical jurisprudents assert that a theory of law consists of necessary, universal truths about the nature of law. This often‐repeated claim, which has not been systematically established, is critically examined in this essay. I begin with the distinction between natural kinds and social artifacts, drawing on the philosophy of society to show that necessity claims about law require a fundamental reworking of basic understandings of ontology and epistemology, which legal philosophers have not undertaken. I show law is a poor fit for a priori and a posteriori knowledge. I distinguish between universal application and universal truth, showing the former is sound while the latter is not. I expose the implications that follow from the initial selection of the central case of law, demonstrating that this choice must be justified, and I reveal two ways analytical jurisprudents shield their theories of law from refutation. This analysis raises significant doubts about the claim by analytical jurisprudents that they are identifying necessary, universal truths about the nature of law.     

The Promise and Problems of Universal,General Theories of Contract Law

There are a growing number of general theories of contract law and of other doctrinal areas. These theories are vastly ambitious in their aims. This article explores the nature of these claims, and the motivations for offering such theories, while considering the challenges to success. It is in the nature of theorizing to seek general categories, including doctrinal categories, and to try to discover insights that hold across those categories. However, differences both within a doctrinal area and across legal systems undermine the case for universal and general theories. Also, unjustifiably general theories may distract us from developing properly contextual legal rules, and might even have the unintended effect of legitimating unjust rules.     

An Optimized Centrifugal Method for Separation of Semen from Superabsorbent Polymers for Forensic Analysis

Connection of a perpetrator to a sexual assault is best performed through the confirmed presence of semen, thereby proving sexual contact. Evidentiary items can include sanitary napkins or diapers containing superabsorbent polymers (SAPs), complicating spermatozoa visualization and DNA analysis. In this report, we evaluated the impact of SAPS on the current forensic DNA workflow, developing an efficient centrifugal protocol for separating spermatozoa from SAP material. The optimized filtration method was compared to common practices of excising the top layer only, resulting in significantly higher sperm yields when a core sample of the substrate was taken. Direct isolation of the SAP‐containing materials without filtering resulted in 20% sample failure; additionally, SAP material was observed in the final eluted DNA samples, causing physical interference. Thus, use of the described centrifugal‐filtering method is a simple preliminary step that improves spermatozoa visualization and enables more consistent DNA yields, while also avoiding SAP interference.
