A 2‐Year Study of Δ 9‐tetrahydrocannabinol Concentrations in Drivers: Examining Driving and Field Sobriety Test Performance,,

From November 1, 2010 through November 30, 2012, 1204 whole‐blood samples were confirmed to contain THC alone or in combination with other drugs out of nearly 5000 Orange County, California, drivers suspected of driving under the influence of drugs. The goal of this study was to examine police reports and drug recognition expert evaluations of THC‐positive samples within this 2‐year time frame to determine whether there is a correlation between whole‐blood THC concentrations and field sobriety tests performance on DRE and non‐DRE evaluations. The FSTs prove to be sensitive to impairment by marijuana although as suspected, the findings of this study did not find a correlation between performance on field sobriety tests and the concentration of THC tested in whole‐blood samples. Driving behaviors were also examined and found to be similar to those seen in alcohol impairment. Future studies examining DRE findings are needed to confirm the results.     

A Two‐Year Study of Δ 9 Tetrahydrocannabinol Concentrations in Drivers; Part 2: Physiological Signs on Drug Recognition Expert (DRE) and non‐DRE Examinations,,

Whole blood samples were examined for ?⁹‐Tetrahydrocannabinol (THC) over 2 years in drivers suspected of driving under the influence. Part one of the study examined the link between [THC] and performance on field sobriety tests. This portion examined objective signs, eye examinations and physiological indicators; and their relationship to the presence of THC. Several objective signs were excellent indicators of the presence of THC: red eyes (94%), droopy eyelids (85.6%), affected speech (87.6%), tongue coating (96.2%), and odor of marijuana (82.4%). About 63.6% of THC positive subjects had dialted pupils (room light). THC positive subjects had either rebound dilation or hippus in 88.8% of cases. Pulse and blood pressure (BP) were evaluated to determine any correlation with [THC]. An increased pulse rate correlated well to the presence of THC (88.5%), but not [THC]. BP did not correlate to [THC] and was also a poor indicator of THC in the blood (50% high).     

Risk communication surrounding the Fukushima nuclear disaster: an anthropological approach

The Fukushima nuclear disaster highlighted the relevance of effective risk communication strategies for nuclear accidents. Poor risk communication was evidenced during the crisis and its aftermath. The government’s mishandling of radiation issues generated concern in international nuclear agencies as well as widespread anxiety among Japanese citizens. Based on anthropological research, I will argue that among the negative consequences of the government’s inability to deal with public fears are the citizens’ uncertainty and ongoing distrust toward the government, the safety regulators, and the nuclear industry. I will also suggest that such harmful effects can be mitigated by enhancing transparency of the decision-making process and by implementing participative programs where policy makers, stakeholders, and representatives of the local communities can jointly discuss energy production schemes.     

Place of residence and registration: problems and comparability in the classification of births

In 1973, the classification method for births in Mexico was changed from place of registration to place of mother's residence. "The objective of this work is to analyze how the place of 'customary residence of the mother' has been registered and to determine if the change of classification has some effect [on] the comparability of the information about births in different states. The information analyzed is divided into two periods, according to the way in which it was obtained and processed and the institution responsible for its publication." (SUMMARY IN ENG)     

FIFA’s Hegemony: Examples from World Cup Hosting Countries

The hegemonic power of FIFA over countries hosting its capstone World Cup tournament is worth examining in the context of hegemony theory in International Relations literature. To understand FIFA’s hegemonic role on the global stage, it is best to place it within the context of two major shifts in the international system—power transition and diffusion. This study provides an insight into the dispute between transnational and national law in sports, which FIFA has used to strengthen its hegemony. This has empirical support as seen in four World Cup cases: previous Cups in Brazil (2014) and South Africa (2010) and the forthcoming tournaments in Russia (2018) and Qatar (2022). These cases reveal FIFA’s hegemonic power both through the overruling of national law in favour of transnational law, and by the questionable bidding processes to host the games in Qatar and the Russian Federation. In addition, this study examines whether Switzerland is capable of regulating or restricting FIFA’s hegemonic power. While removing FIFA’s legal status as a non-profit organisation seems not to be an option, the executed amendment of the Swiss anti-corruption law is a step forward. Furthermore, FIFA needs to continue its recently initiated internal reforms.     

Testing Reliability of the Computational Age‐At‐Death Estimation Methods between Five Observers Using Three‐Dimensional Image Data of the Pubic Symphysis,

In an effort to standardize data collection and analysis in age estimation, a series of computational methods utilizing high‐dimensional image data of the age indicator have recently been proposed as an alternative to subjective visual, trait‐to‐phase matching techniques. To systematically quantify the reproducibility of such methods, we investigate the intrascan variability and within‐ and between‐observer reliability in initial scan data capturing and editing using 3D laser scans of the Suchey–Brooks pubic symphysis casts and five shape‐based computational methods. Our results show that (i) five observers with various training background and experience levels edited the scans consistently for all three trials and the derived shape measures and age estimates were in excellent agreement among observers, and (ii) the computational methods are robust to a measured degree of scan trimming error. This study supports the application of computational methods to 3D laser scanned images for reliable age‐at‐death estimation, with reduced subjectivity.     

Psychedelic fungus (Psilocybe sp.) authentication in a case of illegal drug traffic: sporological,molecular analysis and identification of the psychoactive substance

In nature, there are >200 species of fungi with hallucinogenic properties. These fungi are classified as Psilocybe, Gymnopilus, and Panaeolus which contain active principles with hallucinogenic properties such as ibotenic acid, psilocybin, psilocin, or baeocystin. In Chile, fungi seizures are mainly of mature specimens or spores. However, clandestine laboratories have been found that process fungus samples at the mycelium stage. In this transient stage of growth (mycelium), traditional taxonomic identification is not feasible, making it necessary to develop a new method of study.Currently, DNA analysis is the only reliable method that can be used as an identification tool for the purposes of supporting evidence, due to the high variability of DNA between species. One way to identify the species of a distinctive DNA fragment is to study PCR products analyzed by real time PCR and sequencing. One of the most popular sequencing methods of forensic interest at the generic and intra-generic levels in plants is internal transcribed spacer (ITS). With real time PCR it is possible to distinguish PCR products by differential analysis of their melting temperature (Tm) curves.This paper describes morphological, chemical, and genetic analysis of mycelia of psychedelic fungi collected from a clandestine laboratory. The fungus species were identified using scanning electron microscopy (SEM), mass spectrometry, HRM analysis, and ITS sequencing. The sporological studies showed a generally smooth surface and oval shape, with maximum length 10.1?μm and width 6.4?μm. The alkaloid Psilocyn was identified by mass spectrometry, while HRM analysis and ITS sequencing identified the species as Psilocybe cubensis. A genetic match was confirmed between the HRM curves obtained from the mycelia (evidence) and biological tissue extracted from the fruiting bodies. Mycelia recovered from the evidence and fruiting bodies (control) were genetically indistinguishable.
