通信运营企业的质量管理的再提高

现在通信运营企业为了提高服务质量,不断的加强员工培训,制定客户服务规范,使出了浑身解数,但是仍不见服务质量有显著的提高,用户对企业服务质量的投诉仍居高不下。本文就针对通信运营企业再次提高服务质量的问题,提出了价值链质量管理,鼓励企业实行内部营销,以建立一个完整的质量体系,而不是仅仅关注企业中某一个直接面对客户的职能部门。     

Optimal pest control in agriculture

Based on economic methodology we model an ecosystem with two species in predator–prey relationship: mice feed on grain and grain feeds on a resource. With optimizing behavior of individual organisms a short-run ecosystem equilibrium is defined and characterized that depends on the farmer's use of fertilizer and pesticide and on the mice population which, in turn, is affected by pesticides. In that way, a microfounded agricultural production function is derived. Linking a sequence of short-run ecosystem equilibria yields the growth function of the mice population which is thus derived rather than assumed. In each period the farmer harvests all grain in excess of some given amount of seed. If she maximizes her present-value profits, optimal farming is characterized by either using no pesticide or a moderate amount of pesticide or by applying a chattering control. Pest eradication is never optimal. On the other hand, if the farmer takes into account steady-state mice populations only, it may be optimal to eradicate mice or to use no or a moderate amount of pesticide depending on prices as well as on the shape of the grain production function which is determined by microparameters of grain reproduction.

论质量道德建设

质量道德是调节人们质量行为的准则,可以起到抵制、反对、揭露、纠正损害质量的作用。本文分析了质量道德与一般道德的关系,并从心理学角度分析了质量道德的形成机制。     

西方管理控制理论比较与启示

管理控制理论的研究在西方国家已有200余年的历史，了解其发展历史并总结管理控制理论的研究趋势，对于我国发展管理控制理论、改进管理控制实践具有重要意义。本文在对管理控制思想的源起与发展脉络、不同学派管理控制概念的比较与差异以及管理控制系统框架的比较与差异进行探讨的基础上，得出了未来管理控制理论研究的发展趋势。     

Distribution-free tests for comparing several treatments with a control

Abstract  In this paper we propose distribution-free treatments versus control tests for the one- and two-way classifications. The null distribution properties are shown to be equivalent to those of well-known statistics for which critical values have been extensively tabled. Asymptotic relative efficiencies with respect to corresponding normal theory competitors are derived and optimal designs for the allocation of experimental units to the treatments and control are obtained.     

The housing question in Japan

This article first examines how bad housing conditions are in Japan based on international comparisons. The next question is whether the extremely high land prices in Japan can be explained by economic logic. We then turn to more specific housing policy questions that are peculiar to or important in Japan, such as the tax advantages of owning land that have caused under-utilization of land and the reasons why the average size of Japanese rental housing is so small.     

建筑外墙氟碳涂料施工的质量监控

建筑外墙氟碳涂料克服了以往氟碳涂料不能常温固化的缺点，能应用于混凝土等无机材质的表面。由于其具有超耐候性等卓越性能，已受到业主、设计的关注和市场的认可，在外墙饰面中将得到广泛应用。文章浅析了外墙氟碳涂料的材料特性，阐述了外墙氟碳涂料施工阶段的质量事前控制、事中控制和事后控制；对某工程外墙氟碳涂料施工质量缺陷产生的原因进行了分析，提出了相应的预控措施。     

最终控制人特征与上市公司现金股利政策

本文以2002年-2004年上市公司的股利分配数据,实证检验了最终控制人的特征对上市公司现金股利政策的影响.结果表明.上市公司现金股利政策与最终控制人的侵害动机成反比,现金股利的支付率随着最终控制人控制权比例的增加呈先减少后增加的U形变动;两权分离程度越小,派发现金股利的水平就越大,但这种影响主要来自于较高的现金流量权,现金流量权比例越大,派发现金股利的概率和水平也越大;最终控制人性质为政府尤其是地方政府时,上市公司派发现金股利的概率和水平更高.
