南京市中学生自尊心调查与分析

对南京市中学生的235份有效调查问卷表明,目前中学生对自尊状况的体验多数趋于“一般化”,但都较普遍地存在对自尊的焦虑感、敏感性、渴求性、盲目性、积极性并存的特点也很明显。中学生自尊与自尊心理的发生机制源自于教师与伙伴的外部评价,又源自于自身生理状况、能力。气质与童年经历的影响,中学生自尊与自卑心理的平衡机制存在于对理想自我标准的坚持、修正或放弃选择。学校教育培养中学生自尊心的有效切入点是:提高知识水平、培养羞耻感、锻炼意志力、培养尊重他人的品质。     

学生为本--高校德育新观念

"学生为本"的观念认为,大学德育的目的是为学生服务的,内容是根据学生生存、发展和健康成长的需要而确定的,德育的过程不仅是教师教育学生的过程,更应该是在教师的组织和引导下,在参与各种教育和教学活动中自我教育和相互教育的过程;在德育评价中,学生不仅是评价中的对象,也应是这一评价的主体.     

Non uniform exponential bounds on normal approximation by Stein’s method and monotone size bias couplings

It is known that the normal approximation is applicable for sums of non negative random variables, W, with the commonly employed couplings. In this work, we use the Stein’s method to obtain a general theorem of non uniform exponential bound on normal approximation base on monotone size bias couplings of W. Applications of the main result to give the bound on normal approximation for binomial random variable, the number of bulbs on at the terminal time in the lightbulb process, and the number of m runs are also provided.     

Transformation using ( x + 0.5) to stabilize the variance of populations

Transformation is required to achieve homo-scedasticity when we perform ANOVA to test the effect of factors on population abundance. The effectiveness of transformations decreases when the data contain zeros. Especially, the logarithmic transformation or the Box–Cox transformation is not applicable in such a case. For the logarithmic transformation, 1 is traditionally added to avoid such problems. However, there is no concrete foundation as to why 1 is added rather than other constants, such as 0.5 or 2, although the result of ANOVA is much influenced by the added constant. In this paper, I suggest that 0.5 is preferable to 1 as an added constant, because a discrete distribution defined in {0, 1, 2, . . .} is approximately described by a corresponding continuous distribution defined in (0, ≧) if we add 0.5. Numerical investigation confirms this prediction. Received: October 16, 1998 / Accepted: June 10, 1999

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.     

我国股票市场指数及指数证券投资组合

运用主成分分析法分析我国上海和深圳两个交易所几个市场指数对市场变化的反应情 况, 结果表明两个股票市场的综合指数和A 股指数可以反应市场的变化, 而其他指数不能反 映各自代表的股票市场变化. 由于这4 个指数都不是一个好的投资组合, 要得到与指数一致的 投资收益需要构造指数投资组合. 本文利用多因子定价模型, 结合统计分析和优化方法, 从每 个股票市场上选取20 余支股票, 经过适当的组合就可以得到与指数一致的收益.     

An infinite class of PBIB designs

In this paper, an infinite class of partially balanced incomplete block (PBIB) designs of m+1 associate classes is constructed through the use of a series of row-orthogonal matrices known as partially balanced orthogonal designs (PBOD) of m-associate classes. For the purpose, a series of PBOD is obtained through a method described herein. An infinite class of regular GD designs is also reported.     

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.
