Virtopsy,a new imaging horizon in forensic pathology: virtual autopsy by postmortem multislice computed tomography (MSCT) and magnetic resonance imaging (MRI)--a feasibility study

Using postmortem multislice computed tomography (MSCT) and magnetic resonance imaging (MRI), 40 forensic cases were examined and findings were verified by subsequent autopsy. Results were classified as follows: (I) cause of death, (II) relevant traumatological and pathological findings, (III) vital reactions, (IV) reconstruction of injuries, (V) visualization. In these 40 forensic cases, 47 partly combined causes of death were diagnosed at autopsy, 26 (55%) causes of death were found independently using only radiological image data. Radiology was superior to autopsy in revealing certain cases of cranial, skeletal, or tissue trauma. Some forensic vital reactions were diagnosed equally well or better using MSCT/MRI. Radiological imaging techniques are particularly beneficial for reconstruction and visualization of forensic cases, including the opportunity to use the data for expert witness reports, teaching, quality control, and telemedical consultation. These preliminary results, based on the concept of "virtopsy," are promising enough to introduce and evaluate these radiological techniques in forensic medicine.     

Adipocere in postmortem imaging using multislice computed tomography (MSCT) and magnetic resonance imaging (MRI)

A body was found in a local river almost completely converted into adipocere. The corpse was identified as a 78-year-old male who was missed for 13 months. It was assumed that he committed suicide by drowning. The postmortem imaging findings utilizing multislice computed tomography (MSCT) and magnetic resonance imaging (MRI) in this virtopsy case are presented with special focus on the radiologic appearance of adipocere. The loss of signal in MRI and hyperdensities in MSCT up to 1000 Hounsfield units, as well as the increased assessment of the intracranial structures compared with traditional autopsy, are presented.     

Individual Differences and Political Contexts –The Role of Personality Traits and Direct Democracy in Explaining Political Protest

Building on a growing literature concerned with the link between psychological dispositions and political protest behavior, we argue that this relationship is not universal, but rather depends on contextual factors. Political context factors are able to alter the meaning and understanding of participatory repertoires. This, in turn, leads to differential effects of personality on participation. We argue that direct democracy constitutes such a political context that can act as moderating factor with regard to protest participation. In order to test this interaction between person and situation empirically, we conduct a subnational comparative analysis of the Swiss cantons. Hierarchical regression models reveal that the personality traits openness to experience and extraversion affect protest behavior directly. Most importantly, however, the link between openness to experience and protest participation is significantly moderated by direct democracy. This provides evidence for variance in the situational expression of personality traits.
