Systems and Scholarship: The Need to Do Better

Although conscious organized systems thinking stems only from the 1940s, and is hence a very young field, it is more primitive than it ought or needs to be. Evidence for this is given in three areas: the exposition of systems ideas; the relation between systems epistemology and ontology; and the style and tone of presentation of systems work. The first area can be improved rather easily; the second defines the work systems thinkers ought to be doing; the third will be improved only by the adoption of a more modest mien.     

Measurement of Length: The Need for a Better Approach to Teaching

Three hundred and eighty-three children in grades 1–5 were individually interviewed to find out at when they construct unit iteration out of transitive reasoning as described by Piaget, Inhelder, and Szeminska (1960) . The results indicated that most children (72%) construct transitive reasoning by second grade and that most (76%) construct unit iteration out of transitive reasoning by fourth grade. The article explains why traditional instruction produces the poor results revealed by the National Assessment of Educational Progress. It also suggests a better approach to the teaching of measurement that presents problems and encourages children to modify their ways of thinking.     

最小距离固定且优于Gilbert—Varshamov界的码

本文构造了一类GF(q)上的码,其中GF(q)为q个元素的有限域.这些码的冗余取到渐进界r(q,n,7) 4 m,此界优于Gilbert-Varshamov存在界r(q,n,7) 5m.     

The Minimal Requirements Approach to Policy Modelling in Public Planning

This paper argues that an approach to policy modelling in public planning must deal with the existence of conflicts between actors holding constraint sets, rather than players with strategies able to affect each other's payoffs. This approach builds on the policy level language proposed by Shiv K. Gupta and Laurence D. Richards. Operational definitions of modelling variables, conflict situations and potential pairwise coalitions are given. The approach is simple enough to allow manual calculation in small-scale problems and has a matrix notation which enables the use of computer programs for large-scale problems. A conceptual example which illustrates the features of the proposed modelling approach is presented and discussed.

磁浮轨道交通产业培育：技术、规划和全产业链的视角

磁浮轨道交通在建设成本等方面具有比较优势,在环保、安全等多方面具备突出特点.中国已经掌握磁浮轨道交通技术,长沙市和北京市已经取得磁浮轨道交通的建设和运营经验,国内发展磁浮轨道交通及其产业的条件已经形成.为了依托磁浮轨道交通培育磁浮产业,从技术、规划和全产业链等方面,需要采取的措施包括:进一步发展磁浮轨道交通技术并对技术实行专利利用和保护,在交通领域规划磁浮轨道交通,培育磁浮轨道交通产业链和产业集群并推动产业的国际化发展,发挥政府对产业的推动作用.湖南省还可以采取建设株洲"中国动力谷"和发展"长沙轨博会"等会展经济及观赏经济的特别措施.

电子政务系统中面向公众的个性化信息服务模型

电子政务作为Internet的主要应用领域，已受到世界各国的普遍关注。面对公众各种服务需求日趋个性化，如何打破政府职能机构的条块分割，构建一个一体化的虚拟政府，集成各类信息资源，为公众提供“一站式”的、个性化的服务，是当前电子政务理论和实践的热点课题。本文首先提出一个面向公众的“一站式”服务总体框架；其次，将个性化信息服务的概念引入到电子政务系统中，构建一个个性化信息服务模型；最后，运用数据挖掘技术对模型中的关键技术加以实现。     

基于灰色理论的因子分析模型在实际应用中的研究:以服务业发展为例

基于灰色理论的因子分析模型,应用于解决面板数据的因子分析和研究.以中国服务业发展为例建立模型,用每个省份每年的因子综合得分作为元素,构造1行10列的因子综合得分向量,通过灰色理论的技术方法,计算每个省份的因子综合得分向量与最优因子综合得分向量的接近程度,来刻画各省份的服务业发展情况.研究表明大部分省份服务业发展的最优因子灰关联度都还比较低.     

高校公共就业服务个人自愿供给对就业水平影响机理的实证研究

“多中心治理”框架下完善的公共就业服务体系应该是政府供给、市场供给和自愿供给的有效融合,公共就业服务自愿供给机制能否有效弥补政府供给和市场供给的相对不足。文章构建了公共就业服务个人自愿供给影响就业的逻辑回归模型,基于4所高校3336份问卷调查的实际数据进行了实证检验,实证结果表明,无论是基于个体自选择信息还是利用个体志愿者多维行为特征的整合来确定个体志愿者的身份,大学生公共就业服务自愿供给均对就业产生显著正向影响,而且不同类型的公共就业服务自愿供给对就业影响存在显著差异,提供就业信息、传授求职经验、介绍面试技巧3类自愿供给服务对就业影响最显著,而介绍简历制作技巧类自愿供给对提升就业无影响。

The Steady-State Behaviour of a Manpower Planning Model in Which Class Corresponds to Length of Service

We consider a discrete time Markov population model in which class corresponds to length of service. For this particular system it is shown that the steady state distributions of class sizes are independently Poisson. The model is applied to eight firms for which the steady state tenure distribution is evaluated.     

河北省基本公共服务质量测度研究

以河北省11个地级市为研究对象,选取集对分析模型对11地市的基本公共服务质量进行测评,以期为河北省推进基本公共服务均等化以及缩小与京津地区的公共服务差距等相关公共政策的制定提供参考依据.研究结论如下:基本公共服务属优的城市有石家庄、唐山和保定;属良的城市有邯郸和沧州;属中的城市有廊坊和张家口;属尚可的城市有承德、邢台和秦皇岛;属差的城市为衡水.     

A Production Planning and Stock Control Problem in the Textile Industry

This paper describes the techniques used in an enquiry into production planning and stock holding problems encountered by one of our member firms.The investigation of the problem falls into three parts:

1. i)
   The analysis of demand.
    
2. ii)
   The determination of optimum stock levels.
    
3. iii)
   The solution of the allocation problem which arises if the capacity available for the production of stock lines is not equal to the amount required to bring stocks back to the optimum levels. This problem has not been fully investigated, but a proposed method of solution is given in an appendix.
