Anderson's classification statistic based on a post-stratified training sample

The performance of Anderson's classification statistic based on a post-stratified random sample is examined. It is assumed that the training sample is a random sample from a stratified population consisting of two strata with unknown stratum weights. The sample is first segregated into the two strata by post-stratification. The unknown parameters for each of the two populations are then estimated and used in the construction of the plug-in discriminant. Under this procedure, it is shown that additional estimation of the stratum weight will not seriously affect the performance of Anderson's classification statistic. Furthermore, our discriminant enjoys a much higher efficiency than the procedure based on an unclassified sample from a mixture of normals investigated by Ganesalingam and McLachlan (1978).     

The duration of unemployment in Russia

This paper uses longitudinal survey data to assess factors affecting the duration of unemployment in Russia. We examine four types of marginalised labour force participants, according to ILO guidelines and survey responses, and we estimate duration models for each type. It turns out that the sets of characteristics with the strongest effects on the duration are remarkably similar across the different unemployment definitions and model specifications. Therefore, despite the formidable practical measurement problems, problematic groups of individuals can actually be identified. Received: 27 January 1999/Accepted: 27 January 2000     

The Dutch people and the euro: A structural equations analysis relating national identity and economic expectations to attitude towards the euro

National identity, macro and micro economic expectations affect the attitude toward the euro. In a study in The Netherlands, data were collected and relationships between the latent concepts were modelled with LISREL. In the best fitting model, national identity has a direct and an indirect effect on attitude, respectively, an unstructured and a structured effect. The indirect effect is mediated by macro and micro expectations. Macro expectations also have a direct and an indirect effect. The indirect effect is mediated by micro expectations. On one hand, macro expectations form a strong link between national identity and attitude. On the other hand, macro expectations have a strong direct effect on attitudes. The euro is mainly perceived and evaluated in a macro-economic perspective.PsycINFO classification: 2229; 3920

我国中小企业研究理论中存在的偏差——兼论将微型企业从小企业中独立出来的意义

在企业研究理论中,由于缺乏对企业性质的真实把握,忽视了对经微型企业的研究,使得我国对中小企业研究得出的结论的可信度缺乏说服力,表现在对企业性质的理解把握不准确;对中小企业划分标准的合理性缺乏理论依据;对中小企业生存机理缺乏说服力;对中小型企业的社会经济功能的理解把握不准;理论界与区域政府相比,对中小企业的重视程度不够。因此,在我国中小企业研究中,应增加对微型企业的深入探讨。     

论毛泽东诗词的用典特色

运用典故,是我国古典诗词的传统表现手法,毛泽东同志继承和发扬了这一传统,在诗词创作中从不同角度以不同方式遣词造句、传情达意表现现实生活,大大增强了作品形象性和艺术感染力。探讨毛泽东用典特色,化用诗句、神话入诗和民谚民谣的使用。毛泽东的诗词用词风格与曹操、辛弃疾进行纵向比较,彰显出毛泽东使用典故的豪迈气魄。     

试论教育公平与社会分层

改革开放以来，我国的社会分层结构越来越复杂，以先赋地位为主的社会分层模式逐渐被以自致地位为主的分层模式所取代，分层的标准多元化和人格化改变了传统的“世袭”身份的保守倾向，特别是社会成员的权力、收入、声望和机会越来越取决于个人的受教育程度，这使人们对教育公平有了新的追求，即充分实现教育机会均等。文章重点分析了教育与社会分层之间的互动关系，并对如何实现城乡教育公平进行了探讨。

关于汉语熟语问题的讨论

俄国科学院语言研究所维特罗夫·巴维尔·巴夫罗维奇(Vetrov Pavel Pavlovich)先生来信询问汉语熟语各个类别的定义及划分标准问题,本文结合具体例子,提出熟语类别的划分应该采用基于原型的范畴理论,而不是经典的范畴化理论;并指出熟语的分类采用的并不是一维标准,而是多维标准.很多熟语的类别归属不是非此即彼,而是亦此亦彼.     

湖南省城市等级体系分析

在一个国家或者区域，因城市所处的内外条件不同会形成城市间不同的职能分工，同时也形成不同的城市规模。利用湖南各市的人口数据，讨论湖南省的城市人口规模体系及分布特征，表明湖南省城市规模呈现相对均衡的等级分布，并分析其首位度不高的形成原因。为了提高城市体系的整体实力，湖南提出了长株潭一体化和“3＋5”城市群的发展策略。
