Death due to accidental primary hypothermia in cold climates is relatively common, with previous case series reflecting this. In contrast, hypothermia‐related death as a result of an underlying medical cause, such as a brain tumor, is rare. The literature clearly illustrates a theoretical causal relationship between brain neoplasms and hypothermia through the infiltration of the hypothalamus; however, the number of reported cases is minimal. Two cases are presented where autopsy confirmed hypothermia as the cause of death with both cases revealing widespread glioblastoma multiforme in the brain. Both decedents were elderly with a number of comorbidities identified during autopsy that could explain death; however, hypothermia was deemed the most likely cause. It is proposed that both decedents died of hypothermia as a result of the tumor's effect on thermoregulation. These cases underline the importance of forensic pathologists to be aware of the relationship between brain tumors and hypothermia and to not dismiss death as being due to other disease processes. 相似文献

Migration is as old as mankind. So are the fears and hopes attached to it by the different parties directly or indirectly concerned. Wars, poverty and humanitarian crises have been one steady producer of – mostly involuntary – migration. The pursuit of economic advantage has been another major driver of migration, by those who left their home in the hope of a better life elsewhere. Sometimes, immigrants met with a hearty welcome in the destination country, especially if they brought with them skills needed but in short supply in the destination country. Mostly, however, the reaction of those at the receiving end was at best mixed, and often outright hostile. Experts agree that the surprising thing about migration is not how often it occurs, but how rare it is. Up to now, human beings have shown a strong resistance to move away from their home ground. As long as conditions at home do not become absolutely unbearable, or the expected benefits of moving elsewhere are not extremely high, the human race seems to prefer to ‘stay put’. However, it must also be stressed that the movement pattern and distribution of millions of migrants are not evenly spread across the globe. European countries are amongst those with the highest share of foreign nationals. It is therefore perhaps better understandable that there is a major public debate about the pros and cons of migration in Europe. Copyright © 2016 John Wiley & Sons, Ltd. 相似文献

This paper explores the effectiveness of European Parliament candidates' campaigns. We analyze the relationship between candidates' spending and their likelihood of success, controlling for a range of relevant co-varying factors. We then investigate whether the effects of electoral spending are conditioned by two variables: ballot design and incumbency. We find that, ceteris paribus, spending was positively related to a candidate's likelihood of electoral success in the 2009 campaign, though this effect is small in scale. We also reveal that the electorally positive effects of spending are observable across both 'party-centered' and ‘candidate-centered’ ballot structures, and that there is some evidence that incumbent spending is less effective than challenger spending. 相似文献

In democracies, a constant tension exists between the stability and integrity of the community as a whole, and the desire to ensure minorities a voice in politics. Reserved seats and reduced thresholds are two common means by which ethnic minorities gain legislative seats, though little or no empirical work exists testing their efficacy in this regard. Combining multivariate analysis with in-depth case studies, this article shows that both reserved seats and lower thresholds increase minority representation, though reserved seats accomplish that goal more consistently. Reduced thresholds tend to increase the share of votes and seats won by ethnoregional parties but reserved seats do not. Additionally, Mauritius' unusual best-loser system aids both minorities and ethnoregional parties. 相似文献

This article discusses the important role that Signals Intelligence (Sigint) has played, and continues to play, in the war against international terrorism. It sets out what is known or can be authoritatively established about the role that Sigint played in the events leading up to the terrorist attacks on September 11, 2001, especially the performance of America's Sigint organization, the National Security Agency (NSA). The article also analyzes what the potential future role of Sigint may be in the war on terrorism given the ever changing nature of terrorist operations, the growing number of technological impediments to effective Sigint collection against terrorist targets, and shifting geostrategic considerations on the part of the nations engaged in the fight against the international terrorists. 相似文献

Although declining political engagement has been identified as a key problem for advanced liberal democracies, this article suggests that a more profound tension needs to be addressed. Specifically, it identifies interdependences between growing political pressures on national governments, and the tendency to delegate decisions away from control by elected politicians. These processes of “hyper-democracy” and “hyper-depoliticization” arguably create and re-enforce political tensions, magnifying a risk of central government “overload.” Through analyzing the arguments of prominent scholars of democracy, the article picks apart these interdependencies and argues for a more balanced approach to democratic governance. 相似文献
