多义复合词的词义与语素义关系计量分析

通过计量的方式从微观层面来研究多义词,即多义复合词的词义与其构成成分——语素义之间的关系,结果表明:语素的多义性使复合词也具有多义性。或者说复合词的多义性来源于构词语素的多义性。由语素的多义性产生的多义复合词,其词义基本上可以由语素的字面意义获得。

Computation of the percentage points and the power for the two-sided Kolmogorov-Smirnov one sample test

Two recursive schemes are presented for the calculation of the probabilityP(g(x)≤S _n (x)≤h(x) for allx∈®), whereS _n is the empirical distribution function of a sample from a continuous distribution andh, g are continuous and isotone functions. The results are specialized for the calculation of the distribution and the corresponding percentage points of the test statistic of the two-sided Kolmogorov-Smirnov one sample test. The schemes allow the calculation of the power of the test too. Finally an extensive tabulation of percentage points for the Kolmogorov-Smirnov test is given.     

A semiparametric method of multiple imputation

In this paper, we describe how to use multiple imputation semiparametrically to obtain estimates of parameters and their standard errors when some individuals have missing data. The methods given require the investigator to know or be able to estimate the process generating the missing data but requires no full distributional form for the data. The method is especially useful for non-standard problems, such as estimating the median when data are missing.     

Properties of Bayes Factors Based on Test Statistics

Abstract.  This article examines the consistency, interpretation and application of Bayes factors constructed from standard test statistics. Primary conclusions are that Bayes factors based on multinomial and normal test statistics are consistent for suitable choices of the hyperparameters used to specify alternative hypotheses, and that such constructions can be extended to obtain consistent Bayes factors based on likelihood ratio statistics. A connection between Bayes factors based on likelihood ratio statistics and the Bayesian information criterion is exposed, as is a connection between Bayes factors based on F statistics and parametric Bayes factors based on normal-inverse gamma models. Similarly, Bayes factors based on chi-squared statistics for multinomial data are shown to provide accurate approximations to Bayes factors based on multinomial/Dirichlet models. An illustration of how the simple form of these Bayes factors can be exploited to generate easily interpretable summaries of the experimental 'weight of evidence' is provided.     

A randomized Baumgartner statistic for multivariate two-sample testing hypothesis

In this paper, multivariate two-sample testing problems were examined based on the Jure?ková–Kalina's ranks of distances. The multivariate two-sample rank test based on the modified Baumgartner statistic for the two-sided alternative was proposed. The proposed statistic was a randomized statistic. Simulations were used to investigate the power of the suggested statistic for various population distributions.     

The disagreeable behaviour of the kappa statistic

It is often of interest to measure the agreement between a number of raters when an outcome is nominal or ordinal. The kappa statistic is used as a measure of agreement. The statistic is highly sensitive to the distribution of the marginal totals and can produce unreliable results. Other statistics such as the proportion of concordance, maximum attainable kappa and prevalence and bias adjusted kappa should be considered to indicate how well the kappa statistic represents agreement in the data. Each kappa should be considered and interpreted based on the context of the data being analysed. Copyright © 2014 JohnWiley & Sons, Ltd.     

论钟评《刘文成公全集》

刘基诗文集版本较多,情况复杂,虽有人曾对此做过专门研究,但钟惺所评辑《刘文成公全集》一书,研究者却未能给予应有的重视①。钟、刘之文在思想情趣及表现形式上迥异,但钟惺在评点《刘文成公全集》时,不置一贬语、极端推崇刘基之文。通过对《刘文成公全集》一书评点内容与钟惺文论主张、思想观点之比较,同时对坊间托名钟惺情况之探讨,可以得出这样的结论题名钟惺评辑《刘文成公全集》一书,其评点者并非钟惺。     

浙江民营企业融资租赁调查

融资问题已成为民营企业发展的一个瓶颈。在国外,融资租赁是仅次于银行贷款的常用融资方式,对解决企业融资问题发挥了重要作用;但目前我国民营企业运用融资租赁方式进行筹资遇到了一定障碍。在此背景之下,本文基于问卷对浙江民营企业融资租赁现状进行调查,通过对资料和数据的整理,分析了民营企业运用融资租赁方式进行筹资的障碍及其原因;并据此提出了一些可行的对策与建议。     

充分就业状态及其发展陷阱

人力资源配置效率高低的根本标志就是就业或失业程度,国际主流经济学把充分就业定义为消灭了非自愿失业的就业状态。市场供求规律调节和市场经济所特有的人口规律发挥作用的必然结果,就是供过于求的劳动力作为失业人口而存在,这是一切市场经济的常态。失业人口流动是市场经济高效率运行的根本原因所在。充分就业作为当今世界各国普遍追求的最优发展状态,归根结底是有利于人的发展的。入世后并正处在社会转型期的现代中国,仍然存在传统非效率就业的巨大路径依赖性,因此应尽快走出"充分就业陷阱"。
