跨国证券投资的法律适用包括证券发行与交易中的法律适用规则。各国有关证券投资的立法存在着差异与冲突,证券投资关系的准据法确定取决于对证券的定性及其适用范围的划定,大致包括证券物权关系、证券合同关系和证券股权关系三方面。其法律适用不仅针对证券发行与交易中的私法关系,也涉及证券监管中的公法关系。因此,应对证券法律关系中的具体问题进行识别,区分其中的私法与公法不同属性,而采用不同的法律适用原则。跨国证券法律适用的发展,主要反映为证券法的直接适用及其域外适用性问题,尤其体现于美国扩大其证券法域外适用的相关立法与司法实践。  相似文献

对英语中“体名动词”进行了探讨 ,阐述了“体名动词”的词义、句型与修辞等内容。认为 :一个“体名动词”一旦和某个似乎没有逻辑的词语搭配起来使用 ,构成修辞语体时 ,便会产生浓烈的形象化比喻效应 ,使语言表达生动形象 ,新鲜活泼 ,产生言已尽而意无穷的美感。  相似文献

传统的教育模式长期以来都是应试教育,课堂教学也以讲授为主,已经不再能够满足社会对人才的需求。当前的英语教育要以提升学生的应用能力为目的进行,将传统的教学模式改变,形成新的英语教学模式,以适应社会对人才的需求,培养学生的语言应用能力为目标,进行新型英语教学模式的设计。下面本文就对以语言应用为目的的高校英语教学设计进行探讨。  相似文献

This article proposes a variables sampling plan that can be applied for sampling inspection of resubmitted lots when the quality characteristic of interest follows the normal distribution. Resubmission of lots for inspection is allowed in some situations where the original inspection results are suspected or when the supplier or producer is allowed to opt for resampling as per the provisions of the contract, etc. The advantages of this proposed variables sampling plan over the existing single sampling variables plan are discussed. Tables are also constructed for the selection of optimal parameters of known and unknown standard deviation variables resampling scheme for specified two points on the operating characteristic curve, namely, the acceptable quality level and the limiting quality level along with the producer and consumer's risks. The optimization problem is formulated as a nonlinear programming where the objective function to be minimized is the average sample number and the constraints are related to lot acceptance probabilities at acceptable quality level and limiting quality level under the operating characteristic curve.  相似文献

In this article, we propose a new mixed chain sampling plan based on the process capability index Cpk, where the quality characteristic of interest having double specification limits and follows the normal distribution with unknown mean and variance. In the proposed mixed plan, the chain sampling inspection plan is used for the inspection of attribute quality characteristics. The advantages of this proposed mixed sampling plan are also discussed. Tables are constructed to determine the optimal parameters for practical applications by formulating the problem as a non linear programming in which the objective function to be minimized is the average sample number and the constraints are related to lot acceptance probabilities at acceptable quality level and limiting quality level under the operating characteristic curve. The practical application of the proposed mixed sampling plan is explained with an illustrative example. Comparison of the proposed sampling plan is also made with other existing sampling plans.  相似文献

In this paper, we present a real-world case realized in Switzerland on behalf of the federal agency in charge of the waste policy. The incineration of urban wastes generates hazardous residues that need specific treatment and/or land-filling technologies. The variety of local situations and appraisals led to the choice of very different solutions. Moreover, proponents were keen to propose new technologies. The purpose of this study was to provide the background for a national policy that would apply to all future projects.  相似文献
