Whole body postmortem magnetic resonance angiography

Computed tomography (CT) and magnetic resonance (MR) imaging have become important elements of forensic radiology. Whereas the feasibility and potential of CT angiography have long been explored, postmortem MR angiography (PMMRA) has so far been neglected. We tested the feasibility of PMMRA on four adult human cadavers. Technical quality of PMMRA was assessed relative to postmortem CT angiography (PMCTA), separately for each body region. Intra-aortic contrast volumes were calculated on PMCTA and PMMRA with segmentation software. The results showed that technical quality of PMMRA images was equal to PMCTA in 4/4 cases for the head, the heart, and the chest, and in 3/4 cases for the abdomen, and the pelvis. There was a mean decrease in intra-aortic contrast volume from PMCTA to PMMRA of 46%. PMMRA is technically feasible and allows combining the soft tissue detail provided by MR and the information afforded by angiography.     

A hopeless case?

In a hollow covered with earth, a herb gatherer discovered a severely decomposed corpse mutilated by scavenging animals. Only small areas of the skin had remained intact. A conspicuous tattoo could still be distinguished on the left upper arm. Despite concrete evidence of violence (fracture in the occipital bone, subdural hemorrhage with a volume of 20 ml), the exact cause of death could no longer be established. Police enquiries identified a person in whom such a conspicuous tattoo had been photographed in an earlier criminal case. Eventually, the deceased person could be identified by DNA analysis of a stored blood alcohol specimen. Considered together, the autopsy findings and the results of the investigation of traces of blood on the putative tool used in the crime indicated that the man had been struck dead and the body had afterwards been buried in the wood. Although the prospects of success had been initially slight, it was not only possible to identify the victim, but also to reconstruct the crime.     

How Exclusive is Assembly Democracy? Citizens' Assembly and Ballot Participation Compared

This paper analyses the difference between two specific forms of citizens’ involvements, namely whether a vote is cast by ballot or in a citizens’ assembly in which people gather in town halls to decide legislative questions in a deliberative manner. We show both theoretically and empirically how citizens’ assemblies and decisions at the ballot box substantially differ not only in terms of their underlying model of democracy, but also in their structural conditions and, thus, with respect to the social inequality of participation. We test our hypotheses in a Bayesian multilevel framework using real participation data collected from 15 political decisions made in a Swiss commune. Our results show that citizens’ assemblies are not only characterised by lower participation rates, but also by a particular composition of the electorate. While citizens’ assemblies are more equal regarding income groups, ballots favour a more equitable participation in terms of gender and age.     

Customizing a commercial laboratory information management system for a forensic genetic laboratory

The need for high-throughput laboratories to comply with regulatory requirements makes data management an important aspect of forensic genetics. A Laboratory Information Management System (LIMS) enables efficient workflows and ensures traceability if designed and implemented properly. We customized a commercial LIMS to support STR typing of reference samples according to in-house defined requirements. The customization focused on data validity, traceability and automated solutions.

Retelling the past,inspiring the future: Waffen-SS commemorations and the creation of a ‘European’ far-right counter-narrative

ABSTRACT

Heinrich Himmler created the Waffen-SS in part as a multinational force, willing to fight for a New Europe based on Germanic blood. After the war, many international Waffen-SS units formed veterans' associations (VAs). Like other VAs, these provided veterans with the chance to engage in ‘memory work’ and to keep alive a sense of comradeship and of valiant sacrifice, as well as an emotional commitment to the fallen. Waffen-SS veterans were, however, alone in celebrating their ‘sacrifices’. Others shunned them for their participation in atrocities. To defend themselves, they developed a counter-hegemonic Second World War narrative that presented the Waffen-SS as uniquely heroic ‘European’ volunteers' against Bolshevism. This counter-narrative, however, only gained resonance with the fall of the Berlin Wall. After 1989, in fact, veterans could seek out and establish sites of public commemoration, not in Western but in Eastern Europe. Hurd and Werther use veterans' journals and books to explore the redeployment of SS ideology in a revisionist version of history. They examine the resurrection of a mass Waffen-SS graveyard in East Ukraine as a telling case history, discussing, not least, the implications of a ‘reconciliation’ of the former German soldiers with both Ukrainian villagers and Red Army veterans. Finally, they explore the significance of the veterans' ‘European’ counter-history for a younger generation of neo-Nazis.
