Cardiac fibromas are benign conditions; however, their location and size may cause ventricular arrhythmias and sudden cardiac death. We report a case of a 68‐year‐old female who died suddenly. Postmortem investigation detected a huge cardiac fibroma in the pars muscularis of the interventricular septum, occupying almost the entire muscular septum, and restricting the volume of left ventricular chamber. Histological examination revealed numerous foci of calcification in the alternating complex interlacing or strictly parallel collagenous fiber mass. Tumor mass was mainly demarcated, but in some places, fibrous infiltration of surrounding working cardiac muscle was found. We present a case when direct tumor involvement in the descending left bundle branches was evidenced. Mainly, the branches of septal fascicle were disrupted, entrapped, and degenerated by the tumor mass. This case report emphasizes that postmortem histological examination of conduction system in all sudden cardiac death cases may substantially improve the accuracy of postmortem diagnosis. 相似文献
<正> 国家对民事合同履行的干预是美国法律中的一个老问题。作为历史惯例,合同法把这种干预归入不能履行(Impossibility of performance)或非法合同之列,其结果是受到干预影响的一方可被免除合同规定的义务。近来,国家干预问题则以新的面目出现于法庭,其中心问题已不再是传统的合同问题。本文的目的在于简略地回顾历史上存在的难题,然后展示那些伴随国家干预的不断增长而出现的新问题。 相似文献
In a review of five recent works on Scandinavian politics and public policy, it is shown that the basis for talking about a Scandinavian model is unfounded. Politics and policies diverge from country to country and within each country from sector to sector as a result of institutional variation. This variation is embedded in institutional history which accounts for strong national path dependency in public policies. However, the institutional set-up at a given point in time also provides political actors with incentives for change. Two of the works reviewed take up this lead as they argue for institutional reform, in one case to protect the welfare state against political erosion, in the other case to facilitate renewed economic growth and improved living standards. The review concludes by arguing for the positive prospects for systematic comparative analysis of Scandinavian politics, providing a mixture of institutional and political similarities combined with theoretically relevant variation. 相似文献
Citizens are increasingly concerned with environmental issues and some of them take contentious political actions or adapt their lifestyles to reduce their environmental footprint. Research finds that there is an eco-gender gap in everyday environmental behaviours, with women more active than men. However, studies of the eco-gender gap have infrequently looked at other forms of pro-environmental political behaviours and focused mostly on young people. We contribute to the literature by examining to what extent older women and men differ in a range of pro-environmental political behaviours, using a unique dataset based on a survey of individuals 64 years and older. We find strong evidence of a gender gap in everyday behaviours and political consumerism, but not in relation to contentious forms of political participation. This gender gap in relation to everyday behaviours and political consumerism diminishes with age. 相似文献
Rapid growth in internationalization of corporate R&D has spurred considerable interest since the 1990s. Foreign R&D is still
mainly driven by the expansion of international production, but technology sourcing has become an increasingly important driver
of dispersion. Actually, differences across sectors and companies tend to obscure the mix of motivations behind the development
of global innovation networks. This paper distinguishes the various drivers of the international dispersion of corporate R&D
in order to elaborate a typology of foreign R&D units, including in emerging countries. This typology is used to discuss the
emergence of differentiated global innovation networks and the location choices by type of R&D unit. It is applied to foreign
R&D projects in Europe in high and low cost countries between 2002 and 2005. It is then used to discuss the weakening attractiveness
of the European Union for R&D activities and the relevant policies that countries can design to attract different types of
units.

Abstract Within the context of the debates on the worldwide rise of populism, this article aims to uncover factors that may reduce the vulnerability of a system to populist challenges. Based on existing theories, Hungary, Latvia and Romania are all susceptible to populism but authoritarian populism has emerged only in Hungary. This puzzle is addressed through examining the process of financial crisis management in the three cases and its impact on the political system. Comparative analysis shows that paternalistic expectations of the state and the government’s willingness to accept Russian support distinguish Hungary from Latvia and Romania. 相似文献
To date, there has been surprisingly little research on separate opinions in legal linguistics literature. Scarce attention has been paid to the linguistic and communicative aspects of how judges frame their disagreements. This paper serves as one of the early attempts to examine the institution of votum separatum, or separate opinion, from a comparative, cross-language perspective using a linguistic methodology. The evidence indicates a clear similarity in terms of how separate opinions are integrated within the respective macrostructures of the US SC opinions and the Constitutional Tribunal judgments. This study demonstrates how judges tend to employ highly formulaic expressions to signal their disagreement despite the absence of clear guidelines to communicate such stances. The analysis of their frequent phraseology demonstrates that declaring votum separatum and providing its justification are two different acts, not only legally but also linguistically, especially in terms of their formulaicity. The Polish and American justifications differ in the degree to which the frequent phraseology reveals peculiarities of judicial argumentation in addition to the presence of strong evaluative concerns.
