从一般条款的争论着手,对比中德侵权法一般条款的立法模式、所保护权益范围、侵权责任的过错和违法性要件,可知中国侵权法所设立的大小搭配的一般条款模式所保护的民事权益过于宽泛,限制了人们的自由发展,故在法律使用上应借鉴德国的模式作目的性限缩。在侵权责任的构成要件上也可借鉴德国的规定。 相似文献

文章引入了对产品质量的分析,将产品质量和数量作为并列的因素进行考察,着重分析了产品质量的内部性问题,并进一步提出了单纯的较大的交易成本和单纯的不对称信息,都不能解释产品质量内部性问题产生的根源,与信息不对称紧密联系的较大的交易成本才是其根源。如何降低这种交易成本就成为政府对产品质量内部性进行管制,提高消费者福利水平的管制重点。 相似文献

Milestone or deadline driven production management is predominant in most manufacturing companies. Problems and other disturbing occurrences tend to see their first daylight during phases where plans are implemented into reality, for example, when production commences, prototypes enter manufacturing and deliveries are expected. Conventional control routines fail to depict the true progress and procedures of the company on an on-line basis, which means that instead of being proactive they serve as means to react to already existing problems. This paper studies the application of advanced visualization techniques to the already existing information embedded in a comany's information infrastructure, and how it can help management to anticipate probable near future pitfalls. By studying those daily operations of a company which share a document relationship with the true manufacturing process, that is, the meta-manufacturing processes, a completely new perspective on the company's value-adding activities is drawn. By mining the existing data reservoirs of a company traditionally difficult management processes, such as product development, vendor integration, production planning, can be analysed and the problems identified in a novel way to react in advance. The paper displays several empirical examples from bulk to one-of-a-kind production where the method has been successfully implemented. 相似文献

This article uses panel data to analyse the effect of domestic credit on the diversification of manufactured exports from developing countries. Given the evidence that export variety of manufactured goods affects productivity positively, the results imply that policy reforms that improve access to domestic credit for firms can raise productivity and hence economic growth in many poor countries. In addition, the results also show that building infrastructure and implementing reforms in governance that improve the quality of government regulations are important for encouraging diversification of manufactured export products in developing countries. 相似文献

In 2001, the National Center for Research Resources (NCRR) directed the 78 General Clinical Research Centers (GCRC) to develop a Research Subject Advocate (RSA) position. The RSA would report directly to the Principal Investigator (PI) of each GCRC and assure compliance of studies conducted on the GCRC with federal regulations and policies. Seven RSAs agreed to be interviewed about their new role. Website documents, electronic correspondence, and presentations at the first annual national meeting of RSAs were scrutinized using discursive analysis to shed light on this new organizational form and its potential for increased protection of human research participants. The RSA role actualizes the ethical principles of respect for persons, justice, and beneficence that are the foundation of the protection of research participants. The results also reveal the regulatory, institutional, collegial, and personal resources and barriers that assist the RSA in the successful implementation of the RSA role. In addition, issues important to the RSAs are described. 相似文献

Canonical correlation has been little used and little understood, even by otherwise sophisticated analysts. An alternative approach to canonical correlation, based on a general linear multivariate model, is presented. Properties of principal component analysis are used to help explain the method. Standard computational methods for full rank canonical correlation, techniques for canonical correlation on component scores, and canonical correlation with less than full rank are discussed. They are seen to be essentially equivalent when the model equation for canonical correlation on component scores is presented. The two approaches to less than full rank situations are equivalent in some senses, but quite different in usefulness, depending on the application. An example dataset is analyzed in detail to help demonstrate the conclusions. 相似文献

For the linear-exponential distribution with increasing hazard rate, exact and explicit expressions for means, product moments and percentage points of order statistics are obtained. Some recurrence relations for both single and product moments of order statistics are also derived. These recurrence relations would enable one to obtain all the higher order moments of order statistics for all sample sizes from those of the lower order 相似文献

Abstract It is important for judges to accurately convey what they intend when speaking to litigants involved in domestic violence. Language has idiosyncratic meaning to perpetrators and to victims. Therefore, it is imperative that judges know and understand the language of domestic violence and use it properly. This editorial comments on some of the pitfalls of improper use of language, its impact, and suggests some solutions. 相似文献
