The rapid further development of computed tomography (CT) and magnetic resonance imaging (MRI) induced the idea to use these techniques for postmortem documentation of forensic findings. Until now, only a few institutes of forensic medicine have acquired experience in postmortem cross-sectional imaging. Protocols, image interpretation and visualization have to be adapted to the postmortem conditions. Especially, postmortem alterations, such as putrefaction and livores, different temperature of the corpse and the loss of the circulation are a challenge for the imaging process and interpretation. Advantages of postmortem imaging are the higher exposure and resolution available in CT when there is no concern for biologic effects of ionizing radiation, and the lack of cardiac motion artifacts during scanning. CT and MRI may become useful tools for postmortem documentation in forensic medicine. In Bern, 80 human corpses underwent postmortem imaging by CT and MRI prior to traditional autopsy until the month of August 2003. Here, we describe the imaging appearance of postmortem alterations--internal livores, putrefaction, postmortem clotting--and distinguish them from the forensic findings of the heart, such as calcification, endocarditis, myocardial infarction, myocardial scarring, injury and other morphological alterations. 相似文献

Steamer accidents, through contact with the bucket wheel, are very seldom today. No publication of such a kind of fatal accident could be found in literature. We present the case of a fatal steamer accident, in which the findings of a blunt traumatization of a person by the ship was completely documented by post-mortem combined multi-slice computed tomography (MSCT) and magnetic resonance imaging (MRI) examinations. A rupture of the aorta was detected using both radiological methods without use of radiopaque material. Radiological examination revealed a comminuted fracture of the thorax vertebrae at the same level as the aortic rupture. Injuries of the soft tissues of the back, caused by the bucket wheel of the steamer, were also diagnosed. In addition to the signs of blunt force trauma the findings of drowning such as an over inflation of the lungs, fluid in the stomach and duodenum were revealed. Furthermore, algological analysis detected diatoms in the lung tissue and blood from the left heart. Therefore, the cause of death was considered being a combination of fatal hemorrhage, caused by the aortic rupture, and drowning. We conclude that virtual autopsy using combined post-mortem MSCT and MRI is a useful tool for documentation, visualisation and analysis of the findings of blunt force trauma and drowning with a large potential in forensic medicine. 相似文献

Abstract: The numbers of elderly men in the prisons of England and Wales has grown significantly over the past decade, and they continue to rise. Based on intensive fieldwork in four English prisons, this article explores the prison experiences of men aged 65 years and over. Some of our interviewees had grown old in prison, some had served previous prison sentences and others (the majority) had been sentenced to a term of imprisonment in later life. These men had no prior experience of imprisonment. We are concerned in this article with the impacts of imprisonment on this prisoner group, and with the ‘hidden injuries’ generated by the prison regime and environment. Prisoners in this age group have to date received little research attention, and scant acknowledgement in policy debates in the United Kingdom. We will argue that those impacts may be magnified, in practical ways, by this inattention. 相似文献

Since the creation of the United Nations in 1945, a dramatic increase has occurred in the volume of international law, particularly in the area of human rights. Today, there are dozens of UN sponsored human rights conventions, and most have been widely ratified. We examine how effective these treaties have been in protecting individual rights and liberties. Specifically, we hypothesize that a positive correlation exists between aggregate human rights treaty ratification over time and an improving global human rights record. We also test whether an observed improvement in a country's human rights record correlates positively to recent human rights treaty ratification. Our results support our hypotheses. 相似文献

The authors examined whether negotiators are prone to an illusion of transparency, or the belief that their private thoughts and feelings are more discernible to their negotiation partners than they actually are. In Study One, negotiators who were trying to conceal their preferences thought that their preferences had leaked out more than they actually did. In Study Two, experienced negotiators who were trying to convey information about some of their preferences overestimated their partners' ability to discern them. The results of Study Three rule out the possibility that the findings are simply the result of the curse of knowledge, or the projection of one's own knowledge onto others. Discussion explores how the illusion of transparency might impede negotiators' success. 相似文献

High public interest today in political communications such as ‘spin’ and in political participation such as electoral turnout suggests that there may be value in exploring the processes by which political messages are produced and consumed, and their inter‐relationship with participation. It may be that what citizen‐voters think of message production influences how they consume political news and publicity (through observing and evaluating), and that the propensity to political participation is subsequently affected. This paper offers a model which traces the production of political communications, starting at their origins in the political class, and flowing via traditional political journalism or controlled media and new media to citizen‐voters who both observe and evaluate them (ie consume them) before, during and after making any political choices. It is hypothesised that the observation and evaluation of message production and content by political consumers influences both their types and levels of participation. Research of this nature into political organisations is relatively rare. Similarly, there is little evidence of investigations into other aspects highlighted in the model: attitudes of the political class towards political communications, the production of political communications before they reach the media and how they are received by the media, and their consumption by citizen‐voters in relation to the propensity to participate in politics.

This paper presents findings from a national survey of ‘potential’ first time voters at the 2001 British general election. It investigates these young people's awareness of the advertising used by the main political parties during this election. Overall what emerges is a young electorate aware of the advertising, who were interested in the election itself and nearly half of whom say they voted in it. Consequently the findings reject the notion that young people are generically unaware of and disinterested in party political messages. In addition the findings indicate that the political parties' print advertisements—to some degree—are penetrating the first layer of young people's message processing, suggesting they are a useful aid in capturing the youth vote.
