论所用权 --与民法所有权的比较分析

所有权是民法 (外 )物权的核心 ,而所用权则是经济法 (内 )物权的核心。创设所用权具有重大的理论意义和实践意义 ,因为这是在财富创造的竞争中赋予人们一种新的权利并使之得到法制的保障 ,这有利于我们坚持“发展才是硬道理”的原则 ,从而把我国的经济建设搞得更好     

西方服务营销研究的世纪回眸

自从营销学作为一门独立的学科以来 ,实体产品的营销一直作为主流学派主宰着理论界和实务界。但在 2 0世纪 80年代 ,服务营销走出了产品营销的窠臼 ,为营销学的发展开拓了新视野。本文借助UMI、EBSCD、ELSEVIER公司的电子文献库 ,对近 5 0年的服务营销研究进行了回顾 ,依各时期研究内容的不同 ,将这五十年的历程划分为四个阶段 ,并对各阶段研究的主要内容和特点作了简要评述

浅析黎巴嫩内乱的历史根源

教派隔阂和教派政治、列强的争夺和外部势力的插手、殖民者的"分而治之"政策、阿以冲突和巴勒斯坦问题是黎巴嫩内乱的四大历史根源.它们是在漫长的历史中逐步形成并发挥作用的,且呈现出积重难返的态势.要彻底结束黎巴嫩的内乱局面,只有逐步实现四个目标:教派利益服从民族国家利益;排除外部势力的恶性干扰;建立平等友好的黎叙关系;实现黎以关系正常化并最终公正地解决巴勒斯坦问题.     

完善公司治理，构建良好的内部控制环境

内部控制是解决当前我国一些企业内部管理松弛、制度弱化、会计信息失真以及从源头上治理腐败的重要手段之一。公司治理结构为内部控制提供了外部环境,内部控制为公司治理的有效运作和实施提供了制度保障,只有通过建立完善的公司治理结构,达到公司与所有利害相关者之间利益关系的制衡与协调,才能保证公司决策的科学化,最终维护公司各方面的利益,进而保证内部控制体系的建立及作用的有效发挥。     

Empirical Non-Parametric Control Charts: Estimation Effects and Corrections

Owing to the extreme quantiles involved, standard control charts are very sensitive to the effects of parameter estimation and non-normality. More general parametric charts have been devised to deal with the latter complication and corrections have been derived to compensate for the estimation step, both under normal and parametric models. The resulting procedures offer a satisfactory solution over a broad range of underlying distributions. However, situations do occur where even such a large model is inadequate and nothing remains but to consider non- parametric charts. In principle, these form ideal solutions, but the problem is that huge sample sizes are required for the estimation step. Otherwise the resulting stochastic error is so large that the chart is very unstable, a disadvantage that seems to outweigh the advantage of avoiding the model error from the parametric case. Here we analyse under what conditions non-parametric charts actually become feasible alternatives for their parametric counterparts. In particular, corrected versions are suggested for which a possible change point is reached at sample sizes that are markedly less huge (but still larger than the customary range). These corrections serve to control the behaviour during in-control (markedly wrong outcomes of the estimates only occur sufficiently rarely). The price for this protection will clearly be some loss of detection power during out-of-control. A change point comes in view as soon as this loss can be made sufficiently small.

Some remarks on the physical models concerning two different approaches to inference in statistical process control

Summary For technological applications it can be useful to identify some simple physical mechanisms, which, on the basis of the available knowledge of the production process, may suggest the most appropriate approach to statistical control of the random quantities of interest. For this purpose the notion of rupture point is introduced firstly. A rupture point is characterized bym randomly arising out of control states, assumed to be mutually exclusive and stochastically independent. Shewhart's control charts seem to represent the natural statistical tool for controlling a rupture point; however it is shown that they are fully justified only when the hazard rates attached to the causes of failure are constant. Otherwise, typically in the presence of time increasing hazard rates, Shewhart's control charts should be completed by a preventive intervention rule (preventive maintenance). In the second place, the notion of dynamic instability point is introduced, which is specifically characterized by assuming that the random quantity of interest is ruled by a stochastic differential equation with constant coefficients. By discretization, developed according to a possibly new approach, it is shown that the former model reduces to an equation error model, which is among the simplest used in adaptive control, and thus particularly easy to deal with in regard to parameter estimation and the definition of the optimum control rule.
