Planning for the 1950 Censuses of Population and Agriculture

The change from the z of “Student's” 1908 paper to the t of present day statistical theory and practice is traced and documented. It is shown that the change was brought about by the extension of “Student's” approach, by R.A. Fisher, to a broader class of problems, in response to a direct appeal from “Student” for a solution to one of these problems.     

V aR 之下厚尾分布的最优资产组合的收敛性

主要研究在V aR 风险度量之下, 收益具有厚尾性质的资产的投资组合问题. 证明了基于 尾部分布二阶展开的最优投资组合收敛于基于尾部分布一阶展开的最优投资组合. 因此, 对于 V aR 风险度量之下的最优投资组合问题, 如果要求的风险承受水平充分低, 则只需要利用尾 部分布的一阶展开代替厚尾部分布进行近似计算, 就可以达到满意的精度, 从而不需要进行复 杂的高阶运算.     

虚企业与ERP 软件关系研究

简述国内外ERP 的发展过程, 提出虚企业的概念, 指出它与ERP 软件系统的关系, 揭示 ERP 软件中的模型与BPR 之间的内在联系, 探讨其结构的演变过程, 分析引入该概念的意义 和对信息系统研究的影响, 如独立于现有企业实体的企业理论模型的研究, 优化的企业流程、 企业构架的建立; 传统信息系统开发方式的改变, 不应仿照原企业的构架建立企业管理信息系 统; 企业管理信息系统实施方式的改变, 强调理论模型对信息化的企业管理及其实体结构的影 响; 最后指出虚企业发展的过程为软科学的研究提供了一条思路.     

概率准则下的两期投资决策问题

概率准则是以期望收益率为导向的, 是某些情况下投资者的投资决策准则, 它具有一定 的现实指导意义. 在一般情况下, 证券收益率在不同时期的概率分布会不同而且相关. 因此, 提 出了一类概率准则下的两期投资决策问题, 建立了其数学模型. 对于证券收益率为连续及离散 型随机变量这两种情况分别进行了讨论, 给出了求解最优策略的方法及投资决策的步骤, 并举 例予以了说明.     

政府主管部门与市政公用企业的博弈分析

市政公用设施具有公共性、福利性、外部性、垄断性、超余性和秩序性的经济学特征. 政府 主管部门与市政公用企业间存在着委托代理关系. 模型分析的结论证明了: 计划经济体制下市 政公用企业享受的“先用后算、多用多补”的补贴政策是导致激励弱化、成本失控、政府负担加 重的根本原因; 改革初期的“补贴包干”政策在调动企业积极性、减轻政府负担方面取得了一定 的成效, 但是这种做法仅局限于对企业的放权让利, 还存在很多缺陷; 建立现代企业制度及政 府主管部门与市政公用企业间的委托代理关系, 完善激励机制, 可以最大限度地     

基于价值管理的6 I’s 管理模式: 形成与结构

围绕价值管理,分析了基于职能管理的管理知识体系存在的问题,即忽视创新;对企业效用的存在假设越来越偏离实际,从而导致对企业组织中激励的认识偏差,甚至出现目的与手段的倒置;对信息的假设和运用有误;缺乏系统与综合,忽视整合的作用.在此基础上,提出了以价值管理为核心概念建立管理知识体系的观点,并建立了相应的6I's管理模式的框架,分析了有关要素的内涵.     

The Transport System and Society’s Metabolism in the UK

This paper analyses the interrelation between the transport system and measures of resource consumption such as material and energy consumption over a 60-year period (1937–1997) in the UK. Non-motorized transport and time consumption for mobility are estimated in addition to conventional measures of transport. During the period analyzed, the UK population grew by 20% while transport of goods and persons increased more than threefold and material and energy consumption almost doubled. The transport intensity of domestic material input (DMI) doubled to 300 ton-kilometers (tkm) per ton of DMI while the transport intensity of domestic energy consumption (DEC) doubled to 20 tkm per gigajoule (GJ) of DEC. Thus, while the material and energy intensity of GDP declined significantly, a well-established trend in many advanced countries, the transport intensity of materials and energy consumption rose. These findings suggest a close link between transport, economic development, and long-term structural transformations. In the case of personal transport, a rebound effect was also observed: whereas the average speed of transport has greatly increased, the average number of hours per day devoted to personal transport has not declined.     

The Impact of the Therapist's Curiosity on the Treatment Process of Children and Adolescents

Therapists bring their own initiative, interest, and wonder—their professional curiosity—into treatment sessions. Some children and adolescents pull away in reaction to this curiosity, bristling or withdrawing, if only for a moment. This can happen abruptly, even in response to the first hello, but most often it occurs subtly, over the course of treatment. These children and adolescents may be replaying the ruptures in relationships they experienced when they have expressed their own initiative and curiosity to important others in their lives. Therapists need to utilize opportunities to understand the dynamics, explore where the original ruptures may have occurred, and bring the experience into therapeutic focus. Case vignettes illustrate these dynamics.     

Qualitätsmanagement: Entwicklung,Problemfelder und ein integrativer Lösungsvorschlag

Quality Management: History, problems and an integrative modelStarting with a critical examination of the history and the commonly known concepts and systems of Quality Management, the paper discusses a broader understanding of quality in a genuinely managerial perspective. This is shown by generating and applying five basic dimensions of the quality concept. An integrative concept of Quality Management is presented.
