转折类关联词在对外汉语教学中的研究——基于韩国留学生转折类关联词使用情况的调查

转折类关联词是对外汉语教学中的难点之一,通过考察和分析韩国留学生学习和使用的情况,提出将转折词分为“直转、让步、假转”三种类型进行教学的建议,以达到促进对外汉语教学的目的。

政策偏差研究:回顾与展望

政策执行与预期的不一致长期以来吸引了大量研究。文章对关于中国当下政策偏差的研究进行总结,区分为宏观结构和微观行动两个层面,分别进行评述。从宏观层面看,中央—地方、国家—民众关系是最主要的分析框架,条块分割、考核困境、政策适用和民意传导四个问题成为解释政策偏差的基本出发点。从微观层面看,基于不同的行动者假设,如追逐私利、推卸责任和关系先在,出现了利益分化、监督不足和网络匹配三种解释理论。最后本文认为未来可能的研究生长点在于引入历史维度,将文化因素纳入分析之中。     

An adjusted friedman test for the nested design

As far as is known, no distribution-free test for treatment effects in the presence of nested column effects, is available, Therefore anadjusted Friedman-type test is derived, which is asymptotically the same as the Friedman-type test of Mack and Skillings (1980). If the assumption of commensurability holds, the adjustment is made by means of the renumbering of the cells within rows.     

Testable hypotheses in singular fixed linear models

Hypotheses that restrict nonestimable parameters in singular (or overparameterized) fixed linear models are considered nontes table by most aothors and are not allowed by most computer packages. In this article, a different approach is taken and hypotheses are classified as completely testable, partially testable, or nontestable on the basis of the number of degrees of freedom associated with them. The convenience of this approach is illustrated with examples and by developing a related general theory of equivalent hypotheses, reparameterizations, and restrictions. A method of transforming partially testable hypotheses into equivalent completely testable hypotheses is described.     

Manova double linear hypothesis with double linear restrictions

Given the usual normal multivariate linear regression model Y = BX + E, with B subjected to double linear restrictions GBF' = T, a likelihood ratio test criterion for testing the composite linear null hypothesis HBJ' = U; G, F, T, H, J, U specified, is provided. The applications of such tests are discussed by Timm (1980).     

对当代新型组织模式的几点思考

归纳了传统和当代组织模式的分类、特点与缺陷;针对组织模式的先验假设该如何看待的问题,从对传统组织模式和当代新型组织模式的分析中提出了刚性组织模式和弹性组织模式两个模式假说,并构建了相应哲学层面上的新组织模式框架图,阐述了其推动力量和实现构支柱。其推动力量为:与组织生存的空间和时间的匹配;与环境互适;组织能动性得到发挥;对组织未来发展起重要作用的潜因素的适度掌控。实现构架的支柱,即合作中的竞争;沟通;协商;适度平等的文化氛围。     

On the first order regression procedure of estimation for incomplete regression models

This article discusses some properties of the first order regression method for imputation of missing values on an explanatory variable in linear regression model and presents an estimation strategy based on hypothesis testing. This work was carried out before Professor V.K. Srivastava passed away in 2001. The author is grateful to the referees for their illuminating comments on an earlier draft of this paper.     

Contemporaneous and Intertemporal Relationship Between the Consumption of Licit and Illicit Substances by Youth

Using a representative sample of the 1999 National School-based Youth Risk Behavior Survey, this study investigated the risky behavior of cigarette, alcohol, and marijuana consumption by underage students. The research analyzes the contemporaneous and intertemporal relationship between the use of these licit and illicit substances. Evidence of a gateway from cigarettes to marijuana was found; however, prior use of alcohol does not significantly increase the likelihood of currently using marijuana.     

新型职业农民就业能力实证研究——基于7省679个样本数据

就业能力是新型职业农民培育的核心内容.文章首先运用层次分析法构建新型职业农民就业能力评价指标体系,直观地展现出新型职业农民就业能力的构成.然后,基于7省新型职业农民的调研数据采用因子分析法提取了新型职业农民九大就业能力公共因子并得到各自的表达式,实际测度、比较了各省新型职业农民就业能力差异并分析了原因.最后,从个人、省际及政府三方面分别对加强新型职业农民就业能力培育提出了相应的对策建议.
