English Question or Union Question? Neither has Easy Answers

While devolution has provided a stronger political voice for Scotland, Wales and Northern Ireland since the late 1990s, it is only in the past few years that English public opinion appears to have become exercised by the lack of similar arrangements for England. The renewed debates over the character of the Union after the Scottish independence referendum reveal a desire for ‘fair treatment’ of England within a Union conceived as a partnership of equals. At the same time, numerous proposals have been made for devolution of power within England, reflecting long‐held concerns about the territorial hegemony of London. Solutions to the former issue include English votes for English laws and an English Parliament. Solutions to the latter include city‐regions, strengthened local government, the first of these appears to be the government's preferred route, in the light of the recent ‘Greater Manchester Agreement’. However, none of these ‘solutions’ can count on being implemented.     

What Actually Matters? Understanding Attitudes toward Immigration in Switzerland

On 9 February 2014, the Swiss people accepted the popular initiative “against mass immigration” launched by the national‐conservative Swiss People's Party (SVP). This voting outcome has triggered wide‐ranging debates about both the policy on immigrants as well as the future of Switzerland within the European context. Against this background, we evaluate attitudes toward immigration in Switzerland. Using hitherto unexplored survey data of MOSAiCH, our empirical analyses show that already in the year 2013, before the debate about the initiative on mass immigration was in full swing, roughly 53 percent of the 1011 interviewed Swiss citizens stated that immigration should be reduced. Moreover, our estimations indicate that the threats and fears induced by immigration and the will to maintain sovereignty and autonomy are particularly relevant for attitudes toward immigration. By contrast, education and national or personal economic conditions are only weakly related to the immigration issue.     

Development of Forensic Assay Signatures for Ebolaviruses

Ebolaviruses are a diverse group of RNA viruses comprising five different species, four of which cause fatal hemorrhagic fever in humans. Because of their high infectivity and lethality, ebolaviruses are considered major biothreat agents. Although detection assays exist, no forensic assays are currently available. Here, we report the development of forensic assays that differentiate ebolaviruses. We performed phylogenetic analyses and identified canonical SNPs for all species, major clades and isolates. TaqMan‐MGB allelic discrimination assays based on these SNPs were designed, screened against synthetic RNA templates, and validated against ebolavirus genomic RNAs. A total of 45 assays were validated to provide 100% coverage of the species and variants with additional resolution at the isolate level. These assays enabled accurate forensic analysis on 4 “unknown” ebolaviruses. Unknowns were correctly classified to species and variant. A goal of providing resolution below the isolate level was not successful. These high‐resolution forensic assays allow rapid and accurate genotyping of ebolaviruses for forensic investigations.     

Sex Classification Using the Three‐Dimensional Tibia Form or Shape Including Population Specificity Approach

The aims of this study were to enable geometric morphometric sex classification using tibial proximal and distal sexual dimorphism and to evaluate the secular trend of tibial shape/form from the early 20th century to the present day. The study samples consisted of 61 adult tibias from an early 20th‐century Czech population and 57 three‐dimensional tibias from a 21st‐century population. Discriminant function analysis with cross‐validation was carried out to assess the accuracy of sex classification. Shape analysis revealed significant sex differences in both tibial extremities of the 21st‐century sample and in the proximal tibia of the 20th‐century population. Sex‐based divergence varied between the analyzed samples, raising the issues of population specificity and diachronic change. Classification using tibial form was more successful than using tibial shape. The highest values of correct assignment (91.80% and 88.52%) were found using the form from the early 20th Czech population.     

Optimization of a Statistical Algorithm for Objective Comparison of Toolmarks

Due to historical legal challenges, there is a driving force for the development of objective methods of forensic toolmark identification. This study utilizes an algorithm to separate matching and nonmatching shear cut toolmarks created using fifty sequentially manufactured pliers. Unlike previously analyzed striated screwdriver marks, shear cut marks contain discontinuous groups of striations, posing a more difficult test of algorithm applicability. The algorithm compares correlation between optical 3D toolmark topography data, producing a Wilcoxon rank sum test statistic. Relative magnitude of this metric separates the matching and nonmatching toolmarks. Results show a high degree of statistical separation between matching and nonmatching distributions. Further separation is achieved with optimized input parameters and implementation of a “leash” preventing a previous source of outliers—however complete statistical separation was not achieved. This paper represents further development of objective methods of toolmark identification and further validation of the assumption that toolmarks are identifiably unique.     

Preliminary Validation of Handheld X‐Ray Fluorescence Spectrometry: Distinguishing Osseous and Dental Tissue from Nonbone Material of Similar Chemical Composition

One of the tasks of a forensic anthropologist is to sort human bone fragments from other materials, which can be difficult when dealing with highly fragmented and taphonomically modified material. The purpose of this research is to develop a method using handheld X‐ray fluorescence (HHXRF) spectrometry to distinguish human and nonhuman bone/teeth from nonbone materials of similar chemical composition using multivariate statistical analyses. The sample materials were derived primarily from previous studies: human bone and teeth, nonhuman bone, nonbiological materials, nonbone biological materials, and taphonomically modified materials. The testing included two phases, testing both the reliability of the instrument and the accuracy of the technique. The results indicate that osseous and dental tissue can be distinguished from nonbone material of similar chemical composition with a high degree of accuracy (94%). While it was not possible to discriminate rock apatite and synthetic hydroxyapatite from bone/teeth, this technique successfully discriminated ivory and octocoral.     

Better than Fuller: A Two Interests Model of Remedies for Breach of Contract

The attempt to combine the contractual interests properly so‐called with the restitution interest in the Fuller and Purdue three interests model of remedies for breach of contract is ineradicably incoherent. Stimulated by reflection on contemporary restitution doctrine's understanding of the quasi‐contractual remedies of recovery and quantum meruit, this paper argues that the complete elimination from the law of contract of the restitution interest, which incorporates those remedies into the three interests model, would improve both the coherence of the model of contractual interests and the substantive law of remedies for breach.     

Distribution of ∆9‐Tetrahydrocannabinol and 11‐Nor‐9‐Carboxy‐∆9‐Tetrahydrocannabinol Acid in Postmortem Biological Fluids and Tissues From Pilots Fatally Injured in Aviation Accidents

Little is known of the postmortem distribution of ?⁹‐tetrahydrocannabinol (THC) and its major metabolite, 11‐nor‐9‐carboxy‐?⁹‐tetrahydrocannabinol (THCCOOH). Data from 55 pilots involved in fatal aviation accidents are presented in this study. Gas chromatography/mass spectrometry analysis obtained mean THC concentrations in blood from multiple sites, liver, lung, and kidney of 15.6 ng/mL, 92.4 ng/g, 766.0 ng/g, 44.1 ng/g and mean THCCOOH concentrations of 35.9 ng/mL, 322.4 ng/g, 42.6 ng/g, 138.5 ng/g, respectively. Heart THC concentrations (two cases) were 184.4 and 759.3 ng/g, and corresponding THCCOOH measured 11.0 and 95.9 ng/g, respectively. Muscle concentrations for THC (two cases) were 16.6 and 2.5 ng/g; corresponding THCCOOH, “confirmed positive” and 1.4 ng/g. The only brain tested in this study showed no THC detected and 2.9 ng/g THCCOOH, low concentrations that correlated with low values in other specimens from this case. This research emphasizes the need for postmortem cannabinoid testing and demonstrates the usefulness of a number of tissues, most notably lung, for these analyses.     

Quantitative Phase Analysis by the Rietveld Method for Forensic Science

Quantitative phase analysis (QPA) is helpful to determine the type attribute of the object because it could present the content of the constituents. QPA by Rietveld method requires neither measurement of calibration data nor the use of an internal standard; however, the approximate crystal structure of each phase in a mixture is necessary. In this study, 8 synthetic mixtures composed of potassium nitrate and sulfur were analyzed by Rietveld QPA method. The Rietveld refinement was accomplished with a material analysis using diffraction program and evaluated by three agreement indices. Results showed that Rietveld QPA yielded precise results, with errors generally less than 2.0% absolute. In addition, a criminal case which was broken successfully with the help of Rietveld QPA method was also introduced. This method will allow forensic investigators to acquire detailed information of the material evidence, which could point out the direction for case detection and court proceedings.     

Elemental Analysis of Variably Contaminated Cremains Using X‐ray Fluorescence Spectrometry

Analyzing and identifying skeletal remains becomes increasingly difficult when remains have been cremated, especially in cases where the cremated material may have been intentionally contaminated with nonskeletal material. This study examined the potential of X‐ray fluorescence spectrometry (XRF) to detect the presence of nonskeletal contaminants in samples of cremains. Eleven samples of cremains were variably combined with concrete mix and analyzed using XRF. Photon counts of elements in each sample were analyzed, and the coefficient of determination (R²) using unweighted linear regression as a function of percent cremains was calculated. Results showed that with changes in the proportion of skeletal material and contaminant, there were significant (R² > 0.90) changes in detected levels of phosphorus, potassium, zinc, aluminum, and sulfur. The use of XRF is concluded to be a valid approach in the identification of the presence of nonskeletal material in potentially contaminated cremains.
