论彼得·圣吉的管理哲学

彼得·圣吉是美国著名的管理学家。他的管理哲学从管理理论与管理实践、管理主体与管理客体、管理手段与管理目的、管理组织系统与管理环境之间的关系等四个维度全面揭示了管理科学的发展取向 ,深邃而富有内涵 ,值得我们研究和探讨     

5次交错群A_5的10阶子群的一个构造方法

A5的元最大阶数是5,使用有限群的Lagrange定理,A5的10阶子群元的阶只可能是2,5。但由于拉格朗日定理的逆不成立,因此是否存在A5的10阶子群仍是问题。该文通过对5-循环置换各次方幂的计算及其研究,找到A5的10阶子群元的构成规律,并使用构造性方法给出了5次交错群A5的6个10阶子群。     

RuCl2[P(C6H5)3]2(NH2CH2CH2NH2)催化苯乙酮加氢反应的研究

优化了以RuCl2[P(C6H5)3]2(NH2CH2CH2NH2)作催化剂催化苯乙酮加氢制备α-苯乙醇的反应条件,考察了反应温度、反应压力、碱的用量及不同的碱对反应的影响,得出了一个较好的反应条件.     

屈原与五月五日--端午的渊源及意义

春秋战国各国历法不一,五月五日禁忌原是北方晋、齐等国的习俗,后来才影响到全国,它原本与屈原没有关系.在汉末至南北朝时期,北方厌胜之术与南方救屈原结合起来,才形成了完整的端午节风俗.作为端午节重要内容之一的竞渡在唐代风行于南北,端午风俗在唐代才基本定型;端午使屈原永远活在民俗和民间文化中.     

AN ALGORITHM FOR THE CONSTRUCTION OF OPTIMAL OR NEAR-OPTIMAL CHANGE-OVER DESIGNS

This paper presents an algorithm for the construction of optimal or near optimal change-over designs for arbitrary numbers of treatments, periods and units. Previous research on optimality has been either theoretical or has resulted in limited tabulations of small optimal designs. The algorithm consists of a number of steps:first find an optimal direct treatment effects design, ignoring residual effects, and then optimise this class of designs with respect to residual effects. Poor designs are avoided by judicious application of the (M, S)-optimality criterion, and modifications of it, to appropriate matrices. The performance of the algorithm is illustrated by examples.     

天才的萨克雷与永恒的《名利场》

从介绍英国19世纪批判现实主义小说家萨克雷的生平入手,通过对其代表作《名利场》所完成“描写真实”、“宣扬仁爱”两大任务的深刻揭示,就这位“天才”所显示出来的一系列艺术创新手法进行了评析,并对其存在的历史局限性进行了披露,高度评价了其在英国现实主义小说发展史上坚持真实性原则、不落窠臼而独树一帜的艺术成就。     

A two phases queueing system with Bernoulli vacation schedule under multiple vacation policy

This paper deals with a single server Poisson arrival queue with two phases of heterogeneous service along with a Bernoulli schedule vacation model, where after two successive phases service the server either goes for a vacation with probability p (0≤p≤1) or may continue to serve the next unit, if any, with probability q(=1−p). Further the concept of multiple vacation policy is also introduced here. We obtained the queue size distributions at a departure epoch and at a random epoch, Laplace Stieltjes Transform of the waiting time distribution and busy period distribution along with some mean performance measures. Finally we discuss some statistical inference related issues.

Evaluating employee assistance programs. A review of methods, outcomes, and future directions

Renewed interest in assisting troubled employees has led to an upsurge in the development of employee assistance programs, coupled with demands for demonstrable effectiveness. This review examines the nature and scope of these programs, their administrative and methodological context, and the types and outcomes of evaluation studies conducted thus far. Proposals for improving future investigations through a number of different approaches and strategies are then made.     

价值哲学的认识论转换--乌尔班价值理论研究

从乌尔班的《评价 :其性质及其法则》开始 ,价值哲学的研究主题发生了一种根本性的转变 :由新世界图景的价值哲学建构 ,转向对价值哲学理论的研究。换言之 ,在此之后价值哲学研究结束了形而上学阶段 ,而进入了认识论阶段。在认识论阶段 ,评价问题成为最为重要的研究课题。在对评价问题的研究中 ,乌尔班开创了一种以心理学为基础的经验论研究理路。我国近 2 0年的价值哲学的研究范式与乌尔班开始的美国价值哲学的研究范式十分相似。
