Dancing on coke: smuggling cocaine dispersed in polyvinyl alcohol

Recent trends suggest that cocaine smugglers have become more and more inventive to avoid seizures of large amounts of cocaine transported between countries. We report a case of a mail parcel containing a dance pad which was seized at the Customs Department of Brussels Airport, Belgium. After investigation, the inside of the dance pad was found to contain a thick polymer, which tested positive for cocaine. Analysis was performed using a routine colorimetric swipe test, gas chromatography coupled with mass spectrometry and nuclear magnetic resonance spectroscopy. The polymer was identified as polyvinyl alcohol (PVA) and contained 18% cocaine, corresponding to a street value of € 20,000. Laboratory experiments showed that cocaine could be easily extracted from the PVA matrix. This case report reveals a new smuggling technique for the transportation of large amounts of cocaine from one country to another.     

Forensic identification of urine using the DMAC test: a method validation study

Forensic scientists may sometimes be asked to identify the presence of urine in cases such as harassment, rape or murder. One popular presumptive test method uses para-dimethylaminocinnamaldehyde (DMAC), favoured because it is simple, rapid and safe. This paper confirms that DMAC reacts with urea rather than creatinine, ammonia or uric acid. Sensitivity studies found that the 0.1% w/v DMAC solution currently used for urine identification detects levels of urea found in other body fluids, potentially resulting in false positives. A 0.05% w/v solution was found to be more appropriate in terms of sensitivity to urea however the test is still not specific for urine, giving positive reactions with a number of body fluids (saliva, semen, sweat and vaginal material) and other substances (foot lotion, hair removal cream and broccoli).     

Neighborhood Disadvantage and Neuropsychological Functioning as Part Mediators of the Race–Antisocial Relationship: A Serial Mediation Model

Objectives

We test a serial multiple mediation model in which the relationship between ethnicity and antisocial behavior is sequentially mediated by disadvantaged neighborhoods and impaired neuropsychological functioning.

Methods

Parental and self-report measures of antisocial behavior were assessed in a community sample of 341 adolescent males and females. Neighborhood disadvantage was assessed from census data. Neuropsychological functioning was evaluated using a computerized battery. Separate serial multiple mediation models were tested using non-executive functioning and executive functioning.

Results

The serial mediation model for executive functioning was supported, with the pathway from race to antisocial behavior through neighborhood disadvantage and executive functioning in serial accounting for 10.8% of the total effect of race on antisocial behavior.

Conclusions

Findings support social neurocriminology theory by integrating neighborhood disadvantage and executive functioning as sequential mediators of the race–antisocial relationship. To our knowledge, these are the first findings to explain the race–antisocial relationship in terms of connected social and neuropsychological processes. While this pathway is significant, the effect is still relatively small and thus should be understood as one of many mechanisms through which race may affect antisocial behavior. From a translational science standpoint, the identification of neurocognitive mechanisms by which neighborhood disadvantage predisposes to antisocial behavior suggests the potential benefits of cognitive enhancement techniques to remediate the negative effects of adverse neighborhoods on brain functioning in at-risk minority groups.

     

The Publius Paradox

At the Philadelphia convention assembled to draft a new Constitution, Alexander Hamilton argued ‘[e]stablish a weak government and you must at times overleap the bounds. Rome was obliged to create dictators’. Publius then expands upon this argument in several ways in the Federalist. I suggest that Publius identifies a dynamic or mechanism, the ‘Publius Paradox’, that warrants great attention: under particular conditions, excessive weakness of government may become excessive strength. If the bonds of constitutionalism are drawn too tightly, they will be thrown off altogether when circumstances warrant. After illustrating and then analysing this ‘Publius Paradox’, I turn briefly to its implications, the main one being that constitutional law should be cast as a loosely‐fitting garment – particularly the executive component of the constitution and the scope of executive powers.     

Vom Extremtyp zum Normalfall? Die schweizerische Konsensusdemokratie im Wandel: Eine Re‐Analyse von Lijpharts Studie für die Schweiz von 1997 bis 2007

Can Switzerland still be seen as an extreme case of federal consensus democracy, as illustrated by Arend Lijphart (1999)? A reanalysis of Lijphart's study of the Swiss political system from 1997 to 2007 clearly demonstrates that a consensus democracy has emerged that bears strong tendencies toward adjustment and normalization of the original exceptional Swiss case to the rest of the continental European consensus democracies. Switzerland can be considered a typical, rather than extreme, case of consensus democracy.     

Bestimmungsgründe der Parteienvielfalt in den deutschen Bundesländern

Which factors are decisive for the extent of the legislative party fragmentation in the German Laender? While the institutional approach stresses the importance of the electoral design, the sociological theory considers the degree of heterogeneity within a society and the resulting cleavages the determining factors. In this article hypotheses are derived from both theories. The analysis of these hypotheses is based on aggregate data. It is shown that religious heterogeneity exerts the greatest influence on party fragmentation. Besides, factors of socio-economic modernisation matter while the only institutional variable of relevance is district magnitude.     

Is the Treatment of Economic Loss by the Australian Courts in Torts Cases Anomalous?

The well developed economic theory of tort liability has never been able to comfortably accommodate negligence cases causing pure economic loss as opposed to physical damage or injury. In fact, contrary to received opinion, Australian Courts at least, are increasingly allocating pure economic losses to achieve predominantly an efficiency objective, with corrective justice notions relegated into the background. Consequently, it is difficult to classify these cases as anomalous in the sense of falling outside the efficiency paradigm.JEL Classification: K13     

Impulsivity in Juvenile Delinquency: Differences Among Early-Onset, Late-Onset, and Non-Offenders

The present research investigated differences in levels of impulsivity among early-onset, late-onset, and non-offending adolescents. 129 adolescents (114 males, 15 females), of whom 86 were institutionalised (M age=15.52 years) and 43 were regular school students (M age=15.40 years) participated. Each participant completed the Adapted Self-Report Delinquency Scale, Stroop Colour and Word Test, Time Perception task, Accuracy Game, Risk-Taking Game, and the Eysenck Impulsiveness Questionnaire. Results suggest that adolescents who display rapid cognitive tempo, poor mental inhibitory control, and high impulsivity are more likely to be early-onset offenders. Offender and non-offender groups showed significant differences on several measures of impulsivity, which may suggest that late-onset offenders acquire or exacerbate impulse-related problems through social mimicry of early-onset offender peers. Potentially important implications for our understanding of delinquency and the design and provision of prevention programs are highlighted.Senior Lecturer in Educational Psychology at the School of Education, The University of Queensland, Brisbane, Australia.

A highly polymorphic STR locus in Cannabis sativa

We report on the first short tandem repeat (STR) locus to be isolated from the plant Cannabis sativa. The STR locus, isolated by a hybrid-capture enrichment procedure, was found to contain a simple sequence repeat motif of 6 bp. This 6 bp repeat motif showed no variation in repeat length but with minor variations in repeat unit sequences. The data show the locus to be highly polymorphic with the number of repeat units ranging from 3 to 40 in 108 screened samples. The observed heterozygosity was approximately 87.04%. The forward and reverse primers (CS1F and CS1R) produced no PCR products in cross-reaction study from 20 species of plants, including highly related species such as Humulus japonicus and Nicotiana tabacum. This hexanucleotide repeat DNA locus could be used to identify cannabis samples and predict their genetic relationship as the test is specific to C. sativa and is highly reproducible.     

Monarchy and Democracy: A Progressive Agenda

The Blair governments since 1997 have seen the single most significant period of constitutional reform in Britain for over a century. However, they leave the monarchy, the institution at the apex of the unwritten constitution, untouched. It is argued that neither inaction nor abolition is advisable, but that reform should be undertaken, with particular attention to the rules of succession and to the royal prerogative powers, notable examples being the powers to declare war, to dismiss parliament, to assent to legislation and to appoint the Prime Minister. Those powers now exercised by the executive should be formally and linguistically separated from the office of head of state, and put on a statutory basis. The achievement of these reforms depends, however, on political will and cannot be initiated by the monarchy itself.
