The incidence of drugs of impairment in oral fluid from random roadside testing

Oral fluid (OF) has become a popular specimen to test for presence of drugs, particularly in regards to road safety. In Victoria, OF specimens from drivers have been used to test for the presence of methylamphetamine (MA) and Δ(9)-tetrahydrocannabinol (THC) since 2003 and 3,4-methylenedioxy-N-methylamphetamine (MDMA) since 2006. LC-MS/MS has been used to test the most recent 853 submitted OF specimens from Victoria Police for 31 drugs of abuse including those listed in the Australian Standard AS4760-2006. At least one proscribed drug was detected in 96% of drivers, of which MA was the most common (77%), followed by THC (42%), MDMA (17%) and the combination of all three (3.9%). Opioids were detected in 14% of drivers of which 4.8% were positive for 6-acetylmorphine and 3.3% for methadone. The incidence of the opioids tramadol (1.2%) and oxycodone (1.1%) were relatively low. Cocaine (8.0%) was as commonly detected as benzodiazepines (8.0%), and was almost always found in combination with MA (7.9%). Samples positive to benzodiazepines were largely due to diazepam (3.5%) and alprazolam (3.4%), with only 0.2% of drivers combining the two. Ketamine was also detected in 1.5% of cases. While the incidences of the proscribed drugs itself are concerning, it is clear that many drivers are also using other drugs capable of causing impairment.     

The prevalence of drugs in injured drivers

In mid 2009 Victoria introduced compulsory drug testing of blood taken from all injured drivers taken to hospital. Δ(9)-Tetrahydrocannabinol (THC), methylamphetamine (MA) and 3,4-methylenedioxy-methylamphetamine (MDMA) are prohibited and if drivers are positive to any amount an automatic penalty is enforced. Laboratory screens were conducted on preserved blood using ELISA testing for cannabis metabolite and methylamphetamines and a fully validated LC-MS/MS method for 105 drugs including THC, amphetamines, opioids, benzodiazepines, antidepressants and antipsychotics and a number of other psychoactive substances using a minimum of two transitions per drug. Conventional GC-testing for ethanol was used to screen and quantify the presence of alcohol. 1714 drivers were tested and showed alcohol in 29% (≥ 0.01 g/100mL) and drugs in 35%. The positive rate for the three drugs prohibited by legislation was 12.5%. The prevalence of THC, MA and MDMA was 9.8%, 3.1%, and 0.8%, respectively. The range of THC concentrations in blood was 2-42 ng/mL (median 7) of which 70% had a concentration of 10 ng/mL or higher. The range of concentrations for MA and MDMA was 0.02-0.4 and 0.03-0.3mg/L (median for both drugs was 0.05 mg/L). Drugs of any type were detected in 35% of cases. The other drugs were largely prescribed drugs such as the antidepressants (9.3%) and benzodiazepines (8.9%). Neither 6-acetylmorphine nor cocaine (or benzoylecgonine) was detected in these cases.     

A versatile technique for the investigation of gunshot residue patterns on fabrics and other surfaces: m-XRF

With heavy-metal-free ammunitions becoming more and more popular, it is necessary to find methods to visualize patterns of those elements in gunshot residues (GSRs) that are not accessible by chemographic coloring tests. The recently introduced millimeter-X-ray fluorescence analysis (m-XRF) spectrometer Spectro Midex M offers an easy way to record mappings of GSRs containing such elements in order to determine shooting distances as well as the general composition of these particles. A motorized stage enables samples of a maximum size of 20 x 20 cm to be investigated, like fabric, clothes, adhesive tapes (Filmolux films), and polyvinylalcohol gloves of shooter's hands. Human tissues can be measured using a Peltier-cooled specimen holder that is mounted onto the stage. As the spot size of the exiting X-rays lies in the millimeter range, which is adequate for the assessment of the residue patterns for shooting distance determination, a significant reduction in measurement time is achieved compared with mu-XRF methods. Test shots with heavy-metal-free ammunitions were performed on different target materials, like pork skin and fabric, and the elemental distributions of Ti, K, and Ga were determined. In order to show the capability of the spectrometer for conventional lead ammunitions as well, a shot series of 5-100 cm shooting distance and an adhesive tape of a shooter's hand were investigated analogously. A comparison of several methods applied in GSR investigation shows the advantages of the m-XRF method.

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.     

Do leadership-dominated parties change more?

It is often assumed that political parties have more fluid party platforms than in the past because internal veto players – like party activists – have lost the power to restrain the office-seeking party elite. Several case studies subscribe to this view. However, there is no systematic assessment of this relationship. Using new data this research note investigates this relationship and finds a clear positive effect of leadership domination on party platform change. With leadership domination increasing over time, our model predicts increasing fluidity in party platforms. This note provides a motivational and a numerical argument in favor of this hypothesis, considers alternative hypotheses and provides empirical evidence for the claim using two different datasets.     

Soziale Ungleichheit in der Informations- und Wissensgesellschaft

Ein zentrales Deutungsangebot angesichts gegenwärtiger — vor allem sozioökonomischer — Wandlungsprozesse ist das Konzept der Informations- und Wissensgesellschaft, das einen signifikanten Bruch mit den Verhältnissen der Industriegesellschaft markieren soll. Wenn sich in diesem Sinne die Konturen eines neuartigen Gesellschaftstyps abzeichnen, so stellt sich die Frage, welche Bedeutung dieser Wandel für die soziale Ungleichheit als einem grundlegenden sozialwissenschaftlichen Forschungsbereich hat. Anhand der einschlägigen Ansätze von Peter Drucker, Daniel Bell und Manuel Castells geht der vorliegende Beitrag dieser Frage nach. Es soll geklärt werden, welche Perspektiven die drei Autoren für die Entwicklung sozialer Ungleichheit aufzeigen und inwieweit sich neue Impulse für die soziale Ungleichheitsforschung ergeben.
