Interpersonal Environment Effects on Political Preferences: The “Middle Path” for Conceptualizing Social Structure in New Zealand and Japan

The effect of interpersonal environment, as measured by the degree of heterogeneity or homogeneity of political party preferences among important others in an individual's social network, was investigated using a national probability sample in Japan and regional sample in New Zealand. In both cultures, the interpersonal environment exerted significant and consistent effects on individual voting preferences. Those who reported inhabiting relatively homogeneous interpersonal political environments (IPEs) displayed a strong tendency to vote for the same political party as the important others in their social network. This effect was robust even after controlling for party identification, attitudes, media exposure, and objectively defined group memberships. Importantly, this tendency was not predicated on the frequency of talk about politics with significant others. Implications are discussed for both micro-level and macro-level theories of social structure and political behavior; an argument is made for the importance of a middle path—the psychology of enduring relationships between people.     

Enhancing Efficiency or Crying over Spilled Milk: The Benefits of Reform

We analyze the welfare gains from the reform of existinggovernment-induced distortions. Our results provide support forpolicies aimed at eliminating monopoly and other types of economicdistortion. Welfare gains over the status quo exist wheneverderegulation occurs. The threat of deregulation can induce amonopoly or cartel to modify its behavior, so a reform policy canprove beneficial even if reform does not actually occur. Optimalpolicy with commitment in fact allows a monopoly to deterderegulation. The possibility of reregulation does not reverse ourresults; the per period welfare gain from reform remainsundiminished.     

Party Competition and Government Formation in Germany: Business as Usual or New Patterns?

The process of coalition formation following the 2017 Bundestag election was the most difficult in German post-war history. For the first time, Germany saw negotiations fail, a minority government being discussed as a real possibility, and the federal president involved as formateur in coalition politics. The aim of this contribution is to explain why government formation was so intricate after the 2017 election. To this end, we trace patterns of party politics and the development of the German party system since 2013. We then study general patterns of government formation at the regional and national levels since the 1990s and evaluate whether these have changed with the advent of the right-wing populist party, Alternative for Germany. Our analysis of the 2017–2018 government formation is based on a novel expert survey of the policy profiles of German parties on various issue dimensions, conducted in 2017. The results show that the continuation of the incumbent coalition government of Christian and Social Democrats was the most likely outcome, and that the Social Democrats were indeed able to enforce a surpassing share of their policy positions in the final negotiation rounds.     

Potency of delta 9-THC and other cannabinoids in cannabis in England in 2005: implications for psychoactivity and pharmacology

Gas chromatography was used to study the cannabinoid content ("potency") of illicit cannabis seized by police in England in 2004/5. Of the four hundred and fifty two samples, indoor-grown unpollinated female cannabis ("sinsemilla") was the most frequent form, followed by resin (hashish) and imported outdoor-grown herbal cannabis (marijuana). The content of the psychoactive cannabinoid delta 9-tetrahydrocannabinol (THC) varied widely. The median THC content of herbal cannabis and resin was 2.1% and 3.5%, respectively. The median 13.9% THC content of sinsemilla was significantly higher than that recorded in the UK in 1996/8. In sinsemilla and imported herbal cannabis, the content of the antipsychotic cannabinoid cannabidiol (CBD) was extremely low. In resin, however, the average CBD content exceeded that of THC, and the relative proportions of the two cannabinoids varied widely between samples. The increases in average THC content and relative popularity of sinsemilla cannabis, combined with the absence of the anti-psychotic cannabinoid CBD, suggest that the current trends in cannabis use pose an increasing risk to those users susceptible to the harmful psychological effects associated with high doses of THC.     

Headspace solid-phase microextraction (HS-SPME) and liquid-liquid extraction (LLE): comparison of the performance in classification of ecstasy tablets. Part 2

Headspace solid-phase microextraction (HS-SPME) is assessed as an alternative to liquid-liquid extraction (LLE) currently used for 3,4-methylenedioxymethampethamine (MDMA) profiling. Both methods were compared evaluating their performance in discriminating and classifying samples. For this purpose 62 different seizures were analysed using both extraction techniques followed by gas chromatography-mass spectroscopy (GC-MS). A previously validated method provided data for HS-SPME, whereas LLE data were collected applying a harmonized methodology developed and used in the European project CHAMP. After suitable pre-treatment, similarities between sample pairs were studied using the Pearson correlation. Both methods enable to distinguish between samples coming from the same pre-tabletting batches and samples coming from different pre-tabletting batches. This finding emphasizes the use of HS-SPME as an effective alternative to LLE, with additional advantages such as sample preparation and a solvent-free process.     

High-Risk Interrogation: Using the “Mr. Big Technique” to Elicit Confessions

Kassin et al. (Police-Induced Confessions: Risk Factors and Recommendation, 2009) provide a detailed and thoughtful analysis of how police interrogation practices might elicit false confessions from innocent suspects. The purpose of this commentary is to provide a brief review of a relatively recent development in Canadian police investigation practice and discuss how this procedure may increase the likelihood of police-induced false confessions. The so-called “Mr. Big Technique” is a non-custodial interrogation tactic wherein suspects are drawn into a supposed criminal organization (actually an elaborate police sting) and subsequently told that to move up in the organization, they must confess to a crime. In this article, we describe this remarkable interrogation technique and discuss issues relevant to the potential induction of false confessions.     

The EDNAP mitochondrial DNA population database (EMPOP) collaborative exercises: organisation, results and perspectives

This paper presents an overview of the organisation and the results of the collaborative exercises (CE) of the European DNA Profiling (EDNAP) Group's mitochondrial DNA population database project (EMPOP). The aim of the collaborative exercises was to determine whether uniformity of mtDNA sequencing results could be achieved among different laboratories. These were asked to sequence either the complete mtDNA control region or the two hypervariable regions HVI (16024-16365) and HVII (73-340) from DNA extracts, buccal swabs or bloodstains, proceeding in accordance with the protocol and strategies used in each individual laboratory. The results of the collaborative exercises were employed to identify possible sources of errors that could arise during the analysis and interpretation of mtDNA profiles. These findings were taken as a basis to tentatively make suitable arrangements for the construction of a high quality mtDNA database. One hundred fifty mtDNA profiles were submitted to the evaluating laboratory, and disaccording profiles were classified into four groups corresponding to the source of error: clerical errors, sample mix-ups, contaminations and discrepancies with respect to the mtDNA nomenclature. Overall, 14 disaccording haplotypes (16 individual errors) were observed. The errors included 10 clerical errors, 3 interpretation problems, 2 cases of sample mix-up and 1 case of point heteroplasmic mixture, where the 2 sequencing reactions brought inconsistent base calls. This corresponds to an error rate of 10.7% in a virtual mtDNA database consisting of the collaborative exercise results. However, this estimate is still conservative compared to conclusions drawn by authors of meanwhile numerous publications critically reviewing published mtDNA population databases. Our results and earlier published concerns strongly emphasize the need for appropriate safety regulations when mtDNA profiles are compiled for database purposes in order to accomplish the high standard required for mtDNA databases that are used in the forensic context.     

Involvement of Amphetamines in Sudden and Unexpected Death

Abstract:  In the present study, the effects of amphetamine-class drugs were examined in cases reported to the Victorian coroner from 2001 to 2005 to determine if death can occur from the use of amphetamine-class drugs alone. A total of 169 cases were reviewed where a forensic autopsy detected amphetamine(s) in the blood. Pathology, toxicology, and police reports were analyzed in all cases to ascertain the involvement of amphetamine-class drugs in these deaths. In Victoria, methamphetamine (MA) is the principal abused amphetamine-class followed by methylenedioxymethamphetamine (MDMA). There were six cases in which a cerebral hemorrhage caused death and three cases in which serotonin syndrome was established as being caused by the interaction of MDMA and moclobemide. There were 19 cases in which long-term use of amphetamines was associated with heart disease. There were three cases where amphetamine-class drugs alone were regarded as the cause of death, of which two cases exhibited high levels of MDMA and lesser amounts of MA and/or amphetamine. There were no cases in which significant natural disease was absent and death was regarded as caused by the use of MA. There was no correlation between blood concentration of drug and outcome.
