Pitfalls of Computed Tomography 3D Reconstruction Models in Cranial Nonmetric Analysis*

Many studies in the literature have highlighted the utility of virtual 3D databanks as a substitute for real skeletal collections and the important application of radiological records in personal identification. However, none have investigated the accuracy of virtual material compared to skeletal remains in nonmetric variant analysis using 3D models. The present study investigates the accuracy of 20 computed tomography (CT) 3D reconstruction models compared to the real crania, focusing on the quality of the reproduction of the real crania and the possibility to detect 29 dental/cranial morphological variations in 3D images. An interobserver analysis was performed to evaluate trait identification, number, position, and shape. Results demonstrate a false bone loss in 3D models in some cranial regions, specifically the maxillary and occipital bones in 85% and 20% of the samples. Additional analyses revealed several difficulties in the detection of cranial nonmetric traits in 3D models, resulting in incorrect identification in circa 70% of the traits. In particular, pitfalls included the detection of erroneous position, error in presence/absence rates, in number, and in shape. The lowest percentages of correct evaluations were found in traits localized in the lateral side of the cranium and for the infraorbital suture, mastoid foramen, and crenulation. The present study highlights important pitfalls in CT scan when compared with the real crania for nonmetric analysis. This may have crucial consequences in cases where 3D databanks are used as a source of reference population data for nonmetric traits and pathologies and during bone-CT comparisons for identification purposes.     

Do Civil Wars,Coups and Riots Have the Same Structural Determinants?

The literature on political instability focuses on institutional and leader survival or outcomes like civil wars and coups. We suggest that this approach overlooks lower levels of instability and that isolating outcomes understates the likelihood that they are manifestations of similar structural determinants. We extend the notion of instability to encompass jointly but distinctly civil wars, coups, and riots. Our explanation focuses on the role of political institutions and the related ethnopolitical strife over state power. Using data from 1950 to 2007, we find that the three outcomes share some determinants such as a factional partial democracy and the exclusion from power of a large proportion of the population; the inverted U-shaped effect of political institutions is driven by a subset of semidemocracies; and there is a substitution relationship between civil wars and coups emerging from the composition of governing coalitions.     

Skull and Encephalic Injuries Caused by Beach Umbrellas: Case Reports and Review of Literature

This study reports two unusual cases of skull‐encephalic injuries in bathers that were caused by violent impacts with beach umbrellas. The first case concerned a 36‐year‐old man who, while lying on a sun bed, was struck on his left temple by a beach umbrella, which had been blown away by a gust of wind. The second case concerned a six‐year‐old child who was struck on the right temporal region while he was playing on the sand. Both subjects died. A review of the literature was carried out. Various skull and brain injuries caused by several objects were found, but no injuries caused by beach umbrellas were detected. There were only cases of injuries caused by normal umbrellas. These cases showed that several objects can be responsible for traumas causing skull and brain injuries, therefore forensic investigation must be supplemented by circumstantial data.     

Counterfeit Adderall Containing Aceclofenac from Internet Pharmacies

A nontargeted approach based on liquid chromatography equipped with a quadrupole time‐of‐flight mass detector (LC‐MS Q‐TOF) joined to nuclear magnetic resonance (NMR) analysis allowed rapid identification and quantification of the anti‐inflammatory drug aceclofenac in illegal Adderall tablets. The largest chromatographic peak had m/z = 354.030 and m/z = 376.012 matching, respectively, the ionic structures (M + H)⁺ and (M + Na)⁺ of a molecule M. The accurate mass data generated the molecular formula C₁₆H₁₃Cl₂NO₄. A screening of the pharmaceutical active substances having that molecular formula together with the MS/MS fragmentation pattern suggested aceclofenac. Aceclofenac structure was unambiguously confirmed by ¹H and ¹³C NMR experiments. The aceclofenac content was 90 mg/tablet (RSD 2%) as detected by quantitative NMR. Information on the identity and content of illegal drugs is required for legal purposes; it supports in evaluating the effective impact on users safety, and it is useful for control laboratories using a targeted approach in their analytical activities.     

East Side Story: How Transnational Coalitions Contested EU Conditionality

The literature on Europeanisation in relation to Eastern Europe has posited the material incentives of EU membership as the main driver of domestic reforms aimed at adopting EU rules and norms (conditionality). But this fails to explain puzzling instances where no EU rule exists yet domestic change happens under European influence, or where the rule is a condition yet has little impact. As repositories of (dis)information, transnational networks can embolden a candidate country to breach the rules or influence it to comply with the ‘extra-conditionality’ the networks themselves create out of their own agendas.     

Tacticians,Stewards, and Professionals: The Politics of Publishing Select Committee Legal Advice

At Westminster, there are increasing pressures on select committees to publish in‐house legal advice. We suggest that examining the process of deciding to publish provides useful insights into the provision, reception, and use of legal advice, and the dynamics of select committees generally. We argue that the autonomy of select committees to decide what use they make of evidence and advice they receive is, in practice, constrained by the intra‐institutional dynamics and practices of select committees. Committee actors – parliamentarians, clerks, and parliamentary lawyers – each have overlapping, sometimes competing, roles. Most of the time, these roles and the responsibilities they encompass coincide, but the prospect of publication reveals clear tensions between the different actors. This is the politics of publication: the tactical approach of politicians is in tension with the stewardship of clerks and the professional norms of parliamentary lawyers. We suggest this tension will only increase in the near future.     

An Assessment of How Facial Mimicry Can Change Facial Morphology: Implications for Identification

The assessment of facial mimicry is important in forensic anthropology; in addition, the application of modern 3D image acquisition systems may help for the analysis of facial surfaces. This study aimed at exposing a novel method for comparing 3D profiles in different facial expressions. Ten male adults, aged between 30 and 40 years, underwent acquisitions by stereophotogrammetry (VECTRA‐3D ^® ) with different expressions (neutral, happy, sad, angry, surprised). The acquisition of each individual was then superimposed on the neutral one according to nine landmarks, and the root mean square (RMS) value between the two expressions was calculated. The highest difference in comparison with the neutral standard was shown by the happy expression (RMS 4.11 mm), followed by the surprised (RMS 2.74 mm), sad (RMS 1.3 mm), and angry ones (RMS 1.21 mm). This pilot study shows that the 3D–3D superimposition may provide reliable results concerning facial alteration due to mimicry.
