A Preliminary Validation of the Brief Spousal Assault Form for the Evaluation of Risk (B-SAFER) in Hong Kong

The present study attempted a preliminary validation of the Brief Spousal Assault Form for the Evaluation of Risk (B-SAFER) in Hong Kong. In-depth assessment was conducted on 43 identified batterers and 46 control male subjects. Results suggested that the B-SAFER could correctly classify 95% of the cases. Scores relating to the current situation were found to be particularly important in predicting intimate partner violence. The concurrent validity of the B-SAFER was demonstrated by its correlation with the Conflict Tactics Scale scores. Findings were discussed in the context of developing screening tool in the community setting with the guided clinical approach.     

The Unanimous Voting Rule is not the Political Equivalent to Market Exchange

The unanimous voting rule is often viewed as analogous tovoluntary market exchange. This paper demonstrates that whenthird-party pecuniary effects exist, this analogy breaks downbecause unlike markets, unanimous voting requires compensationfor these effects. Thus, efficient market outcomes typically willbe rejected by the unanimous voting rule. Even when transactionscosts are low enough to make compensation feasible, the political outcome under unanimity will differ from the market outcome. The distributional effects of unanimityprovide the incentive for people to substitute rent-seekingbehavior for productive activity, and reduce the incentive forproductive change, providing additional reasons why a less-than-unanimous voting rule may be optimal when resources are to beallocated politically.     

Differentiation of methylenedioxybenzylpiperazines (MDBPs) and methoxymethylbenzylpiperazines (MMBPs) By GC-IRD and GC-MS

The substituted benzylpiperazines, 3,4-methylenedioxybenzylpiperazine (3,4-MDBP), its regioisomer 2,3-methylenedioxybenzylpiperazine (2,3-MDBP) and four isobaric ring substituted methoxymethylbenzylpiperazines (MMBP) have almost identical mass spectra. Perfluoroacylation of the secondary amine nitrogen of these isomeric piperazines gave mass spectra with differences in relative abundance of some fragment ions. However, the spectra did not yield any unique fragments for specific identification of one isomer to the exclusion of the other compounds. Gas chromatography coupled with infrared detection (GC-IRD) provides direct confirmatory data for the structural differentiation between the six isomers. The mass spectra in combination with the vapor phase infrared spectra provide for specific confirmation of each of the isomeric piperazines. The underivatized and perfluoroacyl derivative forms of the ring substituted benzylpiperazines were resolved on the polar stationary phase Rtx-200.     

Mental sets in conduct problem youth with psychopathic features: Entity versus incremental theories of intelligence

The purpose of the current study was to examine the effect of a motivational intervention on conduct problem youth with psychopathic features. Specifically, the current study examined conduct problem youths' mental set (or theory) regarding intelligence (entity vs. incremental) upon task performance. We assessed 36 juvenile offenders with psychopathic features and tested whether providing them with two different messages regarding intelligence would affect their functioning on a task related to academic performance. The study employed a MANOVA design with two motivational conditions and three outcomes including fluency, flexibility, and originality. Results showed that youth with psychopathic features who were given a message that intelligence grows over time, were more fluent and flexible than youth who were informed that intelligence is static. There were no significant differences between the groups in terms of originality. The implications of these findings are discussed including the possible benefits of interventions for adolescent offenders with conduct problems and psychopathic features.
