Rupture of a splenic artery aneurysm is a rare and usually catastrophic event, most commonly associated with pregnancy. In spite of increasingly common reliance on abdominal angiography, magnetic resonance imaging, and computerized tomography during the past quarter century, clinicians uncommonly recognize any of the various splanchnic arterial aneurysms absent premonitory signs or symptoms. Accordingly, rupture of a visceral aneurysm, including splenic artery aneurysm, typically presents as sudden, unexpected obtundation or death. As a consequence, the initial recognition and diagnosis of splenic artery aneurysm rupture take place only at autopsy. This report presents two such cases of sudden death resulting from splenic artery aneurysm in a pregnant woman and a postpartum woman, respectively.  相似文献

Campaign finance contributions may influence policy by affecting elections or influencing the choices of politicians once in office. To study the trade‐offs between these two paths to influence, we use a game in which contributions may affect electoral outcomes and signal policy‐relevant information to politicians. In the model, a campaign donor and two politicians each possess private information correlated with a policy‐relevant state of the world. The donor may allocate his or her budget to either an ally candidate who has relatively similar preferences or a moderate candidate whose preferences are relatively divergent from the donor's preferred policy. Contributions that increase the likelihood of the moderate being elected can signal good news about the donor's preferred policy and influence the moderate's policy choice. However, when the electoral effect of contributions is too small to demand sufficiently high costs to deter imitation by groups with negative information, this informational effect breaks down.  相似文献

While protests and acts of resistance are central to democracy and the potential for social change, what is often ignored is the usurping of resistance through commodification and consumption. Here we argue that it is important to remember that even acts of resistance, such as we have witnessed since the election of Donald Trump to the Presidency of the United States, that speak out against inequality and social harm are commodified and consumed within the spectacular domination of the State and capital, making resistance part and parcel of the neoliberal system that commoditizes in totality.  相似文献

The aim of this study was to analyze the relevance of callous–unemotional (CU) traits in incarcerated juvenile delinquents. A sample of 160 incarcerated male youths was used. Results showed that youths with high CU traits had an earlier age of crime onset and of trouble with the law, and also had higher levels of conduct disorder. When controlling for age of crime onset, youths with high CU traits showed higher levels of general psychopathic traits and of psychopathy taxon membership as well as lower levels of prosocial behavior, but no differences were found for self-reported delinquency, crime seriousness, impulsivity-conduct problems, and general conduct problems. Also, no significant associations of CU traits with self-reported delinquency and crime seriousness were found when controlling for age of crime onset. Future studies of CU traits should take into account the specific importance of age of onset.  相似文献
