Recent scholarship has demonstrated that the Supreme Court of the United States has defined poorly and inconsistently applied two core First Amendment concepts-content and viewpoint discrimination. This article systematically explores the malleability of the Court's speech discrimination principles. Using data from The Supreme Court Compendium that categorize the ideological voting behavior of justices on the Court, the article studies decisions in three socially divisive areas of law in which content and viewpoint discrimination have been central issues of significant cases. Analysis shows that the Court's weak definitions and inconsistent applications leave the content and viewpoint concepts especially ripe for manipulation. The article concludes, therefore, by suggesting a new method of analysis that would offer more consistency.  相似文献

知识产权保护是推动文化产业发展的重要保障。目前,我国文化产业领域知识产权保护现状不容乐观,著作权保护进程缓慢,商标保护和品牌意识落后,地理标志保护严重滞后,专利权保护的瓶颈有待突破,商业秘密保护意识缺乏,民族传统文化保护遭遇海外挑战。因此,我国文化产业领域知识产权法律保护必须加强版权立法与执法,重视商标保护,实施品牌战略,创新地理标志保护,强化申请资格审查,全方位保护商业秘密,不断加强传统文化的源头保护,唯此,才能不断推进社会主义文化强国建设。  相似文献

A key concern among policymakers and community developers in recent years has been the extent to which lender-owned homes, often called real estate owned or “REO” properties, accumulate in different local housing markets during the mortgage crisis. This paper describes the accumulation of REO properties in 356 metropolitan statistical areas (MSAs) from August 2006 to August 2008. It examines differences in both changes and static levels of REO activity across MSAs and compares changes in REO levels to changes in home values over the same period. Special attention is paid to 12 large MSAs with substantial levels of REO as of August 2008. A model of REO volume at the metropolitan level is estimated that includes differences in state foreclosure legal processes and timing among the independent variables. Finally, cluster analysis is used to identify a simple typology of MSAs based on REO levels and home price changes.  相似文献

根据GenBank中的鸭疫里氏杆菌(RA)外膜磷酸盐选择性微孔蛋白(Porin)基因序列设计特异性引物,以血清1、2、6、10、11、13、14和17型RA菌株的基因组DNA为模板均扩增出大小为1 212bp的目的片段,序列比对显示该基因在8种血清型菌株间同源性均大于99.6%。针对保守性最高的357bp片段设计特异性引物,建立了PCR检测方法,对鸭致病性大肠杆菌、鼠伤寒沙门菌、鸭巴氏杆菌及鸭肝炎病毒均未扩增出目的条带,表明该方法具有较高的特异性;敏感性试验显示最小检出量为73.96pg的基因组。应用建立的PCR方法对分离自吉林、河北及北京的8个菌株进行扩增,均在357bp处扩增出清晰的目的条带,与细菌分离鉴定的符合率达100%。本研究为RA的鉴定提供了新方法,为RA外膜微孔蛋白的后续研究提供了理论依据。  相似文献

While the U.S. struggled to quickly mobilize a coordinated national homeland security office after the September 11 attacks, the National Security Council (NSC) has been responsible for monitoring security in the Republic of China since the Nationalists moved to Taiwan in 1949. Although its primary mission has been to prevent Taiwan from being invaded by Mainland China, recent world events have awakened us to a need for security, a need that seemed to have faded away after the end of the Cold War. Although not a strong probability, Taiwan is still a possible target of terrorism because of its close relationship with the U.S. Thus, it is worthwhile to explore the role of NSC in antiterrorist efforts. The NSC plays a vital role in coordinating executive agencies in antiterrorism efforts. The NSC's antiterrorist measures cover the whole spectrum of the executive branch ranging from law enforcement to non‐law enforcement efforts. The tradition of collaboration among the military, police, and private security in Taiwan may help the NSC to smoothly coordinate these three parties.  相似文献

When people wish to take legal action in relation to damage suffered due to medical procedures carried out overseas, they are faced with complex issues. First, in which country can they sue? Second, which country’s laws will govern the dispute? And third, where can a potential favourable judgment be enforced?

This article examines these private international law issues in the context of medical tourism. In doing so, particular emphasis is placed on investigating the private international law issues that would arise if an Australian citizen wanted to take action against a foreign provider of medical services, in relation to services rendered overseas.  相似文献

After proposing an alternative definition of what “law” (jurisprudential concept) is, this article demonstrates the impossibility of identifying “the law” (what law‐makers announce, relative to a particular jurisdiction) as something that is in a particular way. Rather, the law is a more or less abstract range of options. Drawing upon this conclusion, the article calls for a reassessment of how we view the role of law‐makers. We need to remove the mystery that surrounds the law so as to provide for greater transparency. This transparency can be gained by requiring law‐makers to declare their inescapable biases where they influence their lawmaking.  相似文献

目的寻找SCN2B、SCN4B基因的变异位点,探讨其与青壮年不明原因夜间睡眠中猝死(SMDS)的关系。方法提取SMDS病例组及健康对照组的基因组DNA,采用聚合酶链式反应(PCR)方法扩增SCN2B、SCN4B基因编码区外显子、外显子-内含子交界区以及3'侧翼区序列,直接行DNA测序以明确遗传变异类型。结果在病例组中共检测到4个变异位点,c.237+27AG,c.*38CT,c.174CT(p.C58C)和c.*7CT。结论本研究首次对中国人SMDS病例进行了SCN2B、SCN4B基因的检测,上述基因是否为中国人SMDS的易感基因尚有待进一步研究证实。  相似文献
