跨国企业集团是由在各国成立的不同法律实体以某种形式的控制权或所有权相互连结而形成的经济组织。在欧盟破产法中,跨国企业集团破产管辖权可以分成两个层次:一是基于债务人主要利益中心地的管辖;二是基于债务人营业所所在地的管辖。  相似文献

Psychostimulant use is associated with increased stroke risk. To determine the proportion of psychostimulant users among fatal strokes in young adults (15–44 years), all cases were retrieved from the National Coronial Information System (1/1/2009–31/12/2016). A total of 279 cases were identified: hemorrhagic (259), ischemic (8), thrombotic (8), and mycotic (4). Fifty (17.9%) were identified as psychostimulant users. Psychostimulants in blood were detected in 37/45 where toxicology was available, predominantly methamphetamine (32/45). Hemorrhagic strokes in the psychostimulant group were more likely to be intraparenchymal (OR 2.33). Psychostimulant users were less likely to be obese (OR 0.31), but more likely to have a history of tobacco use (OR 2.64). No psychostimulant user had a previous stroke history, was gravid/postpartum, or diagnosed with cerebral vasculitis or endocarditis. The work illustrates the substantial role of psychostimulant use in fatal strokes among young adults. In cases of hemorrhagic stroke among young adults, psychostimulant use should be considered.  相似文献

Facial approximations based on facial soft tissue depth measurement tables often utilize the arithmetic mean as a central tendency estimator. Stephan et al. (J Forensic Sci 2013;58:1439) suggest that the shorth and 75‐shormax statistics are better suited to describe the central tendency of non‐normal soft tissue depth data, while also accommodating normal distributions. The shorth, 75‐shormax, arithmetic mean, and other central tendency estimators were evaluated using a CT ‐derived facial soft tissue depth dataset. Differences between arithmetic mean and shorth mean for the tissue depths examined ranged from 0 mm to +2.3 mm (average 0.6 mm). Differences between the arithmetic mean plus one standard deviation (to approximate the same data points covered by the 75‐shormax) and 75‐shormax values ranged from ?0.8 mm to +0.7 mm (average 0.2 mm). The results of this research suggest that few practical differences exist across the central tendency point estimators for the evaluated soft tissue depth dataset.  相似文献

目的探讨汉族人上颌中切牙牙根直径及根管管径与年龄的关系。方法 2014年11月~2015年11月间,在一家三甲医院数据库中选择420例汉族人的口腔锥形束CT资料,根据年龄将所有研究对象分为6个组别(8~12岁、13~17岁、18~22岁、23~27岁、28~32岁、33~37岁,每组70例,男女各15例。对所有研究对象上颌中切牙牙根直径及根管管径进行测量,取釉牙骨质界距根尖3/4处,分析上颌中切牙牙根直径及根管管径与年龄的关系,比较男女上颌中切牙牙根直径。结果男性与女性上颌中切牙牙根直径比较具有差异显著性(P0.05);男性与女性上颌中切牙牙根管径比较具有差异显著性(P0.05);男性与女性上颌中切牙牙根直径与牙根管径之比比较具有差异显著性(P0.05);不同性别间上颌中切牙牙根直径与牙根管径之比与年龄具有一定的相关性(R~2=0.623,P0.05)。结论汉族人上颌中切牙牙根直径及根管管径与年龄的变化具有相关性,且男性根管管径减小趋势比女性更高。  相似文献

中央权威是指中央权力在国家权力结构中所享有的独占性威望和最高强制力。中央权威的宪政之道是对国家法治战略之中央权力宪法安排的解读。社会主义法治意识形态是我国宪法精神的集中表达,是央地权力共同的价值基础和信仰支撑;从政策治国向依法治国转变是宪法之依法治国战略的基本要求,它为中央权威提供了更具连续性和公正性的合法性基础;落实全国人大及其常委会的最高监督权和加强中央司法权威的控制力,是宪法国家权力结构的内在需求,也是加强中央权威的根本宪政途径;宪法意义上的地方分权是地方权力对中央权威的一种回应性诉求,也是宪政权力纵向配置的一种内在机理。  相似文献

构建中央与地方纠纷的协商解决模式具有极大的可行性,但是同时又面临着极大的理论和实践阻力。尤为要注意的是,学界将这种协商与政治协商作等同的倾向是存在误区的。同时,在法制化的语境中,在“协商之后的法制化”与“法制框架下的协商”之间也体现出了更多的外在制度区别与内在理念融合并存的特点。  相似文献

ABSTRACT

A diverse group of over 30 countries located all over the world—such as the UK, Colombia, and Ghana—introduced inflation targeting, which is a monetary policy that seeks to control inflation through a pre-announced target. Fully institutionalized democracies adopted the policy first because the core features of inflation targeting are consistent with the principles of a liberal democracy. But why was inflation targeting also introduced by less-democratic countries? This article develops the argument that decision makers of less-democratic countries became more likely to adopt inflation targeting when they observed that nearby countries increased the flexibility of the policy. The statistical analysis of data from 76 countries between 1989 and 2013 supports this hypothesis. The finding that the change of a policy toward a more flexible framework drives its global spread addresses a blind spot in the more recent policy diffusion literature.  相似文献

The study aimed to determine the clinical characteristics of fatal methamphetamine‐related stroke in Australia, 2009–2015. There were 38 cases, 60.5% male, with a mean age of 40.3 years. In no case was there evidence that this was the first time methamphetamine had been used by the decedent, and 52.6% had known histories of injecting drug use. The stroke was hemorrhagic in 37 of 38 cases. In 21.1% of cases, the stroke was purely parenchymal and, in 18.4%, involved purely the subarachnoid space. A ruptured berry aneurysm was present in 31.6% and in 68.8% of initial subarachnoid hemorrhages. There was evidence of systemic hypertension in 8 of 25 cases in which full autopsy findings were available. With increased use of methamphetamine, there is a high probability of increased hemorrhagic stroke incidence among young people. In cases of fatal hemorrhagic stroke among young cases presenting to autopsy, the possibility of methamphetamine use should be borne in mind.  相似文献

全面建成小康社会离不开政府引导、保护、协调等功能的有效发挥,而引导功能无疑是首要之需,作为两大主体的中央政府、地方政府,既具有相向的表达、又具有紧密的关联。中央政府的引导功能主要通过规范授权、财政控制、政策工具、指标考核等方式实现,地方政府的引导功能作用主要通过实际设计、规划布局、理性选择等方式实现。准确把握两者之间的内在统一性、不可替代性,进一步优化宏观层面的整合设计,加强中观层面的统筹推进,有助于从根本上保证全面建成小康社会的质量和水平。  相似文献
