组织文化度量:本土模型的构建与实证研究

本文旨在构建本土化的组织文化度量模型,并检验模型的有效性.作者在质性研究的基础上,从"组织对利益相关者的价值判断"与"组织对管理行为的价值判断"两个角度来构建我国组织文化度量模型.前者由组织对股东、客户、员工、社会大众等组织利益相关者价值判断维度构成,后者由组织文化动力特征、效率特征、秩序特征与和谐特征四个子模块构成.在验证性因子分析中,假设模型得到了很好的验证.本文最后比较了本土化模型与国外已有的重要模型在研究逻辑和方法上的差异,并对我国企业文化建设实践提出了若干建议.

草地早熟禾主要经济性状间的灰色关联分析

应用灰色关联分析方法研究了坪用草地早熟禾地上生物量、生殖枝数、生殖枝高、穗长、穗粒数、结实率等6个主要经济性状与种子产量以及各性状之间的关联程度。结果表明,各性状与种子产量之间的关联度大小依次为单位面积生殖枝数＞单位面积地上生物量＞生殖技高＞穗长＞结实率＞穗粒数。地上生物量对生殖校高、生殖枝数和穗长的影响较大。     

地方政府土地管理模式更新——农民参与的视角

土地可持续发展是科学发展观的一项重要内容.作为与土地有着最为直接利益关系的农民,其参与土地管理决策不仅合情合理,而且对于维护自身利益和土地可持续发展具有双重意义.然而,当前地方政府土地管理模式中却存在着农民参与有效性不高的问题,这既损害了农民的合法权益,也对土地可持续发展造成负面影响.这一问题的解决需要地方政府进行土地管理模式的更新,即通过制度创新吸纳农民参与到土地管理决策中来.     

民国时期上海对私立学校的管理模式

民国时期上海私立学校特别繁盛。城市教育行政对此采取间接管理的模式,尤其注重借助立案管理的基本手段,规范和引导其办学行为,同时给予适当的经费扶持、公平待遇和充分信任,在经济和办学等环节进行必要的干预。对众多私立学校的间接管理模式大大减轻了上海城市公共教育财政负担,也为城市教育行政集中精力办理宏观教育管理创造了重要的前提。

Testing Inference in Inflated Beta Regressions under Model Misspecification

We consider testing inference in inflated beta regressions subject to model misspecification. In particular, quasi-z tests based on sandwich covariance matrix estimators are described and their finite sample behavior is investigated via Monte Carlo simulations. The numerical evidence shows that quasi-z testing inference can be considerably more accurate than inference made through the usual z tests, especially when there is model misspecification. Interval estimation is also considered. We also present an empirical application that uses real (not simulated) data.     

休谟与启蒙运动——基于《人性论》引言的思想史考察

当前对休谟的研究常把他和启蒙运动相隔裂.通过对休谟代表性著作《人性论》引言的分析,可以发现他和法国启蒙思想家共享认识世界的“力学模式”和实验方法,都试图将当时在英格兰兴起的“自然哲学”应用于人类境况,都致力于用对人类生活有用的经验研究所产生的新理论代替传统形而上学.同时,休谟对经验主义方法自身的局限有着更为健全的认识,主张在经验和可观察现象范围内的实验方法.这一认识在我们反思启蒙时极富价值.     

On the statistical computation of the sample multiple correlation moefficient

Based on the recursive formulas of Lee (1988) and Singh and Relyea (1992) for computing the noncentral F distribution, a numerical algorithm for evaluating the distributional values of the sample squared multiple correlation coefficient is proposed. The distributional function of this statistic is usually represented as an infinite weighted sum of the iterative form of incomplete beta integral. So an effective algorithm for the incomplete beta integral is crucial to the numerical evaluation of various distribution values. Let a and b denote two shape parameters shown in the incomplete beta integral and hence formed in the sampling distribution functionn be the sample size, and p be the number of random variates. Then both 2a = p - 1 and 2b = n - p are positive integers in sampling situations so that the proposed numerical procedures in this paper are greatly simplified by recursively formulating the incomplete beta integral. By doing this, it can jointly compute the distributional values of probability dens function (pdf) and cumulative distribution function (cdf) for which the distributional value of quantile can be more efficiently obtained by Newton's method. In addition, computer codes in C are developed for demonstration and performance evaluation. For the less precision required, the implemented method can achieve the exact value with respect to the jnite significant digit desired. In general, the numerical results are apparently better than those by various approximations and interpolations of Gurland and Asiribo (1991),Gurland and Milton (1970), and Lee (1971, 1972). When b = (1/2)(n -p) is an integer in particular, the finite series formulation of Gurland (1968) is used to evaluate the pdf/cdf values without truncation errors, which are served as the pivotal one. By setting the implemented codes with double precisions, the infinite series form of derived method can achieve the pivotal values for almost all cases under study.
