The tsunami catastrophe of December 2004 left more than 200,000 dead. Disaster victim identification (DVI) teams were presented with the unprecedented challenge of identifying thousands of mostly markedly putrefied and partially skeletised bodies. To this end, an adequate body tagging method is essential. Conventional body bag tagging in terms of writing on body bags and placing of tags inside body bags proved unsatisfactory and problem prone due to consequences of cold storage, formalin (formaldehyde) embalming and body numbers inside storage facilities. The placement of radio frequency identification device (RFID) microchips inside victim bodies provided a practical solution to problems of body tagging and attribution in the DVI setting encountered by the Austrian DVI team in Thailand in early 2005.  相似文献

Estimating the postmortem interval of skeletal remains is difficult, as few tools exist to do so. To address this problem, we conducted a field experiment to measure the chemistry of swine (Sus scrofa domesticus Linnaeus) gravesoil after 1 year and 3 years postmortem. Carcasses were placed on the soil surface of a pasture during June in a cold (Dfa) climate. Significant (p < 0.05) increases in ninhydrin‐reactive nitrogen, pH, total nitrogen, and nitrate in gravesoil were detected 1 year postmortem. Significant differences in gravesoil chemistry were not detected 3 years postmortem. These observations coincided with gaps in plant growth 1 year postmortem and the development of lush vegetation 3 years postmortem. We conclude that these phenomena can be used to assist the decision‐making process regarding the allocation of resources during the early stages of a death investigation.  相似文献

Contemporary us counterinsurgency doctrine in Iraq and Afghanistan requires junior leaders to engage in both combat and state-building activities. This study aims to explain the fundamental challenge in merging these. I argue that difficulty lies in separating insurgents from civilians, and translating doctrine from senior to junior officers. Junior officers consistently develop a similar ad hoc decision-making tool— role-switching—to simplify complex situations to a binary of “hostile or not.” They understand themselves to fill only two roles, the violent “on” role and the non-violent “off” role and develop several tools to minimize the difficulty of role-switching, help their subordinates switch, and signal switching to local populations. Ultimately, however, problems with role-switching—role stickiness, inappropriate switching, and role bias—can in some cases encourage indiscriminate and excessive violence, pointing to the fundamental failures of using military forces as a one-size-fits-all solution to state-building projects abroad.  相似文献

Existing research considers issue ownership to be a positive attribute of political parties, which are seen as ‘owning’ those policy areas where they are particularly competent and engaged. However, for some citizens a party may also be a negative issue owner if it has a particularly bad reputation for its handling of an issue. This article describes and explains aggregate and individual-level patterns of negative issue ownership using a survey-based measure of handling perceptions from the 2013 Austrian National Election Study (n = 3,266). Naming a particular party as a negative issue owner is affected by partisanship, but also by policy preferences and government performance evaluations. The effects of issue importance vary across issues. These findings lay the groundwork for more research on negative attributions of issue ownership and their empirical consequences on vote choice.  相似文献

This study describes the prevalence of adverse events and length of stay in forensic psychiatric patients with and without a restriction order. Detailed clinical and administrative information from medical records and written court decisions was gathered retrospectively from admission until discharge for a Swedish population-based, consecutive cohort of forensic psychiatric patients (n = 125). The median length of stay for the whole cohort was 951 days, but patients with a restriction order stayed in hospital almost five times as long as patients without. Restriction orders were related to convictions for violent crime, but not for any other differences in demographic or clinical variables. The majority of the patients (60%) were involved in adverse events (violence, threats, substance abuse, or absconding) at some time during their treatment. Patients with restriction orders were overrepresented in violent and threat events. Previous contact with child and adolescence psychiatric services, current violent index crime, psychotic disorders, a history of substance, and absconding during treatment predicted longer length of stay. Being a parent, high current Global Assessment of Functioning scores, and mood disorders were all significantly related to earlier discharge. In a stepwise Cox regression analysis current violent index crime and absconding remained risk factors for a longer hospital stay, while a diagnosis of mood disorder was significantly related to a shorter length of stay.  相似文献
