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。     

电子商务立法的国际比较及对我国的启示

电子商务的迅速发展实质性地改变了传统市场交易的形式。而作为法律调整和规范的主要对象之一，交易形式的变化要求有新的法律规定与之相适应。在国际上，关于电子商务的立法活动已经形成了一种浪潮。而我国的电子商务立法工作却一直进展缓慢。其中有认识上的问题，更主要的是立法经验的不足。借鉴有关国家电子商务立法的先进经验，我国应当尽快建立和完善电子商务法制，这其中包括应当建立关于电子签名、电子商务认证、电子合同、电子支付等方面的法律规则与制度。

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.

论行为管理手段的“四制”关系

管理行为不同层次的矛盾有其特殊性,可以选择不同的方法加以解决。制度在行为管理手段中有其适用范围,此外,机制、“人制”、自制也是行为管理的另外三种有效手段,这四种行为管理手段有着各自的特点和适用范围,有鉴别地应用好这四种行为管理手段,可以有效地解释行为管理的现象,并可指导行为管理实践。
