民间精神与荒诞的权力运作机制——论刘震云《我不是潘金莲》的叙事伦理     

汪树东 《海南师范大学学报(社会科学版)》2013,(8):74-78,133

刘震云持之以恒地关注权力对人性、对社会生活的深刻影响。他最新的长篇小说《我不是潘金莲》中,被权力挟持的荒诞生活更是被他提升到一种寓言化、传奇化的境界。在游刃有余、幽默迭出、清简传神的明清话本风格般的叙述中,刘震云展示了敢于担当的民间精神对荒诞社会的不公不义的反抗,暴露出了社会的权力运作机制的荒诞性,从而逼迫人们深入反思当今社会的可能出路。这无疑是富有启示性的叙事伦理指向。  相似文献   

Accuracy of Estimates and Statistical Power for Testing Meditation in Latent Growth Curve Modeling     

JeeWon Cheong 《Structural equation modeling》2013,20(2):195-211

The latent growth curve modeling (LGCM) approach has been increasingly utilized to investigate longitudinal mediation. However, little is known about the accuracy of the estimates and statistical power when mediation is evaluated in the LGCM framework. A simulation study was conducted to address these issues under various conditions including sample size, effect size of mediated effect, number of measurement occasions, and R ₂ of measured variables. In general, the results showed that relatively large samples were needed to accurately estimate the mediated effects and to have adequate statistical power, when testing mediation in the LGCM framework. Guidelines for designing studies to examine longitudinal mediation and ways to improve the accuracy of the estimates and statistical power were discussed.  相似文献   

Evaluation of a New Mean Scaled and Moment Adjusted Test Statistic for SEM     

Xiaoxiao Tong  Peter M. Bentler 《Structural equation modeling》2013,20(1):148-156

Recently a new mean scaled and skewness adjusted test statistic was developed for evaluating structural equation models in small samples and with potentially nonnormal data, but this statistic has received only limited evaluation. The performance of this statistic is compared to normal theory maximum likelihood and 2 well-known robust test statistics. A modification to the Satorra–Bentler scaled statistic is developed for the condition that sample size is smaller than degrees of freedom. The behavior of the 4 test statistics is evaluated with a Monte Carlo confirmatory factor analysis study that varies 7 sample sizes and 3 distributional conditions obtained using Headrick's fifth-order transformation to nonnormality. The new statistic performs badly in most conditions except under the normal distribution. The goodness-of-fit χ² test based on maximum-likelihood estimation performed well under normal distributions as well as under a condition of asymptotic robustness. The Satorra–Bentler scaled test statistic performed best overall, whereas the mean scaled and variance adjusted test statistic outperformed the others at small and moderate sample sizes under certain distributional conditions.  相似文献   

Graphical Extension of Sample Size Planning With AIPE on RMSEA Using R     

Tzu-Yao Lin 《Structural equation modeling》2013,20(3):482-490

Kelley and Lai (2011) recently proposed the use of accuracy in parameter estimation (AIPE) for sample size planning in structural equation modeling. The sample size that reaches the desired width for the confidence interval of root mean square error of approximation (RMSEA) is suggested. This study proposes a graphical extension with the AIPE approach, abbreviated as GAIPE, on RMSEA to facilitate sample size planning in structural equation modeling. GAIPE simultaneously displays the expected width of a confidence interval of RMSEA, the necessary sample size to reach the desired width, and the RMSEA values covered in the confidence interval. Power analysis for hypothesis tests related to RMSEA can also be integrated into the GAIPE framework to allow for a concurrent consideration of accuracy in estimation and statistical power to plan sample sizes. A package written in R has been developed to implement GAIPE. Examples and instructions for using the GAIPE package are presented to help readers make use of this flexible framework. With the capacity of incorporating information on accuracy in RMSEA estimation, values of RMSEA, and power for hypothesis testing on RMSEA in a single graphical representation, the GAIPE extension offers an informative and practical approach for sample size planning in structural equation modeling.  相似文献

关系的应用非常广泛.在数学领域对关系的研究主要集中在关系的性质上,很少有人研究关系的存储结构和算法.本文主要论述了二元关系的邻接矩阵存储结构和在此结构之上的关系的创建和合成运算.并利用C语言实现了该算法.最后分析了算法的复杂性.  相似文献   

村民自治制度运行中的路径依赖问题分析     

杨刚 《大理师专学报》2013,(7):94-97

村民委员会自治制度是与我国依法治国战略的实施和市场经济体制的改革相适应的农村基层管理制度。村民自治制度30多年的实践已经取得了一些成效,在农村基层民主政治建设方面有了新的发展。但在该制度的现实运行中,原有制度惯性的影响是村民自治制度健康持续发展中一个不容忽视的问题。  相似文献
