“Truncated” society: The eastern European cases

The multicultural experience of the author inspires a reflection on the persistence of certain negative features in several societies despite profound transformations not only outside and even also inside them. In the post-communist reality of eastern Europe, the national reconstruction meets obstacles originating not only from the rigid nature of the Soviet style state socialism and the one party rule, but also from the pre-communist heritage. The inability to deal with the past and take a constructive approach to the present and to the future is behind the phenomenon of truncation, preventing the given society to enter the road of a substantial reconstruction in the conditions of free market economy of the Western style democracy.     

Natural advantages and contractual justice

Anthony Kronman has argued that libertarians cannot distinguish non-arbitrarily between legitimate and illegitimate advantage-taking in contractual relations except by reference to a liberal, wealth-redistributive standard Kronman calls paretianism. We argue to the contrary that libertarians need not concede that any advantage-taking in contracts is legitimate and thus need not be liberal paretians with respect to advantage-taking.     

Practical benzylation of N,N-substituted ethanolamines related to chemical warfare agents for analysis and detection by electron ionization gas chromatography–mass spectrometry

The benzylation of three low molecular weight N,N-disubstituted ethanolamines related to chemical warfare agents (CWAs) to furnish derivatives with improved gas chromatography-mass spectrometry (GC-MS) profiles is described. Due to their low molecular weight and polar nature, N,N-disubstituted ethanolamines are notoriously difficult to detect by routine GC-MS analyses during Organisation for the Prohibition of Chemical Weapons (OPCW) proficiency tests (PTs), particularly in scenarios when they are present at low levels (~1–10 ppm) amidst more abundant interferences. Our studies revealed that the optimal derivatization conditions involved the treatment of the ethanolamine with benzyl bromide in the presence of an inorganic base (e.g., Na₂CO₃) in dichloromethane at 55°C for 2 h. This optimized set of conditions was then successfully applied to the derivatization of N,N-dimethylethanolamine, N,N-diethylethanolamine and N,N-diisopropylethanolamine present separately at 1 and 10 μg/mL concentrations in a glycerol-rich matrix sample featured in the 48th OPCW PT. The benzylated derivatives of the three ethanolamines possessed retention times long enough to clear the massive glycerol-containing matrix interferences. The protocol herein is introduced as an alternative method for derivatization of these CWA and pharmaceutically important species and should find broad applicability in laboratories where routine forensic analysis is carried out.     

Form follows function: Applying photographic content analysis to forensic firearm identification

Drawing forensic conclusions from an image or a video is known as “photographic content analysis.” It involves the analysis of an image, as well as objects, actions, and events depicted in images or video. In recent years, photographic depictions of objects suspected as illegal firearms have substantially increased, appearing on CCTV surveillance footage, captured by mobile phones and shared on social media. However, the law in Israel states that a person can be charged with illegally possessing a firearm only if it can be proven that the object is capable of shooting with lethal bullet energy. This becomes more challenging in cases where the firearm was not physically seized, and the evidence exclusively consists of images and video. In this study, photographic content analysis was applied to images and video where objects suspected as commercial or improvised firearms had been depicted. An image and event sequence reconstruction video databases of both firearms and replicas were created in order to better define firearm-specific functional morphological features. We demonstrate that it is possible to classify an object as a firearm by analyzing the functional, and not only the esthetic, morphology in images and video. It is also shown that event sequence reconstruction in video may be used to infer that an object suspected as a firearm has the capacity to shoot by confirming the occurrence of a shooting act or shooting process. Thus, photographic content analysis may be used to forensically establish that an object depicted in an image or a video is a firearm by ruling out other known scenarios, and without physically seizing it.     

Adolescent Health Risk Profiles: The Co-Occurrence of Health Risks among Females and Males

This analysis examines the complexity of adolescent health risk behaviors using data from the National Longitudinal Study of Adolescent Health (Add Health), a nationally representative study of students. The current sample includes 12,955 students (6,626 females and 6,329 males) in grades 9 through 12. Cluster analysis was conducted separately by gender to examine the interrelationships among eight health risk behaviors: sexual activity, general alcohol use, binge drinking, cigarette use, marijuana use, other illicit drug use, fighting, and suicide. Four distinct clusters for females and males were identified based on their profiles of risk-taking behavior. Females and males both report low- and high-risk profiles, and a risk profile with high alcohol use and sexual activity. Females have two distinct risk profiles, one that is highest on every measure of risk compared to others and one that has high levels of fighting and suicide with little participation in substance use or sexual activity. Males have a distinct risk profile with particularly high rates of marijuana use and suicidal behaviors. Few distinctions exist between profiles based on sociodemographic characteristics.

A DNA-based approach for the forensic identification of Asiatic black bear (Ursus thibetanus) in a traditional Asian medicine

Attempts to prevent illegal trade in bile and gallbladders from Asiatic black bears, Ursus thibetanus, are hampered by difficulties associated with identifying such items. We extracted DNA from bile crystals of unknown species origin and generated partial cytochrome b (cyt b) sequences using either universal primers (positioned in conserved regions of cyt b), or primers designed on existing U. thibetanus sequences (UT). Species origin was determined by aligning resolved sequences to reference sequence data. The universal primers were unsuitable for U. thibetanus identification when multiple species templates were present in the samples. The UT primers amplified U. thibetanus DNA from all sample extracts, including those containing mixed species templates. The amplified fragment can distinguish U. thibetanus from the most closely related species, U. americanus, a distinct advantage of DNA sequencing over the methods currently used to analyze suspected U. thibetanus bile.
