Validation of LUCIO-Direct-ELISA kits for the detection of drugs of abuse in urine: application to the new German driving licence re-granting guidelines

LUCIO-Direct-enzyme linked immunosorbent assay (ELISA) tests were validated for the screening of drugs of abuse cannabis, opiates, amphetamines and cocaine in urine for the new German medical and psychological assessment (MPA) guidelines with subsequent gas chromatographic-mass spectrometric (GC-MS) confirmation. The screening cut-offs corresponding to 10 ng/mL 11-nor-delta-9-tetrahydrocannabinol-9-carboxylic acid (THC-COOH), 50 ng/mL amphetamine, 25 ng/mL morphine and codeine and 30 ng/mL benzoylecgonine were chosen at the point where the number of false negatives was lower than 1%. Due to their accuracy, ease of use and rapid analysis, these ELISA tests are very promising for cases where a large proportion of the tests are expected to be negative such as for abstinence monitoring as part of the driving licence re-granting process.     

Does the truth come out in the writing? Scan as a lie detection tool

We tested the accuracy of Scientific Content Analysis (SCAN), a verbal lie detection tool that is used world-wide by federal law enforcement and military agencies. Sixty-one participants were requested to write down the truth, an outright lie or a concealment lie about activities they had just completed. The statements were coded with SCAN and with another verbal lie detection tool, Reality Monitoring (RM). RM discriminated significantly between truth tellers and outright liars and between truth tellers and concealment liars, whereas SCAN did not discriminate between truth tellers and either kind of liar. Implications of the findings for the suitability of SCAN as a lie detection tool are discussed.     

Parental warmth amplifies the negative effect of parental hostility on dating violence

Past research has documented the positive association between parental hostility and offspring involvement in intimate partner violence. Researchers, practitioners, and parents typically adopt the standpoint that parental warmth may counter these negative lessons. However, Straus and colleagues argue that parents foster IPV to the extent that they teach their child that verbal and physical aggression are a normal and legitimate component of loving relationships. A strict interpretation of social learning theory would suggest that these lessons are more, not less, likely to occur when parental hostility is interspersed with displays of affection. The present study tests this idea using data from 2,088 undergraduate students from a large university in the Southeast. Consistent with Straus' arguments, findings suggest that, rather than attenuating the negative effects of hostility, supportive interactions seem to amplify the probability that offspring will emulate aggressive behaviors in their own romantic relationships. The same is true for the effects of harsh parenting for women. It seems that the best way parents can avoid contributing to their child's chances of being in a violent dating relationship is to eschew family interaction involving verbal and physical aggression.     

Improved budgeting and financial management as a tool for enhancing the performance of local government in developing countries

Rapid economic and social changes in developing countries are impacting on their governments' ability to manage those changes, and local governments in these countries are becoming the core of decentralization experiments. This article examines the problems local governments face in meeting the challenges of rapid transformation and change. This paper suggests that budgeting be used as a means for strengthening local governments' abilities to deal with such changes. Until now, budgeting has not been used as a key intervention tool for strengthening local governments. A working model to assess the state of financial and related management conditions of local governments is provided. This model can serve as a useful point of reference for change agents involved in the strengthening of local governments.     

The Trouble with Targeted Killing

Students of comparative military organizations have advanced three hypotheses to explain when armed forces adopt more liberal manpower policies: when a major security threat looms, when the military professionalizes, or when the surrounding society grows more tolerant of difference. This article argues that all three are theoretically and empirically problematic: they potentially have much to contribute, but only in conjunction with a perspective that is more appreciative of the centrality of political processes. Enduring reform of the military's participation policies is more productively viewed through the lens of the struggle over national and communal identity. To illustrate the power of this alternative approach, this article reconsiders cases commonly cited in support of the existing hypotheses: the racial desegregation of the U.S. military, the integration of the Druze into the Israel Defense Forces, and the imperial and independent Indian armies' policies with respect to what the British termed “class.”
