The Formal Delegation of Regulatory Decisions in the Telecommunication Sector: An Explanation Using Classification Trees

Research on regulation has traditionally focused on studying the delegation of regulatory competencies from political principals to an independent regulatory agency. In this article, we argue that this delegation is nuanced by different factors that affect whether a specific regulatory decision is formally delegated. We examine and explain formal delegation patterns at the level of individual regulatory decisions in twelve countries located in Europe, Latin America, and South Asia. The data were gathered by coding the twelve countries' telecommunications legislation. The data analysis was undertaken using a classification tree model—a nonparametric model. We found that the maturity of the market has the greatest effect on the formal delegation of regulatory decisions, but this effect is also influenced by the other theoretical factors considered, particularly the level of political constraints and the type of regulation.

猪生殖与呼吸综合征病毒CH-1a株GP5蛋白基因的表达及其单克隆抗体的制备

将猪生殖与呼吸综合征病毒(PRRSV)CH-1a株GP5蛋白基因信号肽部分删除后克隆于pGEX-6p-1载体上,并在大肠埃希氏菌中进行表达。经SDS-PAGE电泳分析发现,融合表达的rtGP5蛋白约42 ku,将融合蛋白rtGP5用PRRSV阳性血清进行Western-blotting分析,证实所表达的融合蛋白能被其特异性识别。收获融合表达产物rtGP5,按50μg/只的剂量与等量弗氏佐剂乳化,经腹腔免疫BALB/c小鼠3次后,取脾细胞与SP2/0骨髓瘤细胞进行融合,分别以融合蛋白rtGP5和GST蛋白为抗原,通过间接ELISA方法对融合细胞的上清液进行检测,筛选阳性克隆,结果得到了15株能稳定分泌抗rtGP5蛋白抗体的阳性细胞克隆株。经间接免疫荧光检测发现,获得的15株单克隆抗体都能与PRRSV感染细胞产生特异性荧光。15株单克隆抗体亚型鉴定结果显示均为IgG1型,且轻链均为κ链。     

美国法典1404(a)与非方便法院原则辨析

由于美国法典28卷1404（a）条款的立法规定在功能与措辞上均非常类似普通法上的非方便法院原则,因此很多学者误以为该立法规定与非方便法院原则之间并不存在实质性的差异。然而,这一看法并不正确。事实上,1404（a）条款立法在法律效果、证明标准以及具体适用方面均与非方便法院原则存在显著的区别。

中药外敷对哮喘豚鼠肺组织IL-5基因表达的影响

目的:探讨中药循经敷贴治疗哮喘的作用机制。方法:采用Hutson法复制豚鼠模型,治疗组隔日诱喘后用中药敷贴30 m in,对照组隔日诱喘后采用9.0 g/L氯化钠注射液浸润纱布敷贴,比较记录诱喘潜伏期时间。两周后处死豚鼠,取肺组织,用半定量RT-PCR法比较IL-5 mRNA的表达。结果:中药循经敷贴能显著延长豚鼠诱喘潜伏期,下调哮喘豚鼠肺组织IL-5 mRNA的表达。结论:抑制炎性细胞因子IL-5 mRNA的表达可能是中药循经敷贴治疗哮喘的重要机制之一。
