Assessing Model Similarity in Structural Equation Modeling

Two models can be nonequivalent, but fit very similarly across a wide range of data sets. These near-equivalent models, like equivalent models, should be considered rival explanations for results of a study if they represent plausible explanations for the phenomenon of interest. Prior to conducting a study, researchers should evaluate plausible models that are alternatives to those hypothesized to evaluate whether they are near-equivalent or equivalent and, in so doing, address the adequacy of the study’s methodology. To assess the extent to which alternative models for a study are empirically distinguishable, we propose 5 indexes that quantify the degree of similarity in fit between 2 models across a specified universe of data sets. These indexes compare either the maximum likelihood fit function values or the residual covariance matrices of models. Illustrations are provided to support interpretations of these similarity indexes.     

英国共识政治述评

在战后英国政治发展中 ,英国两大政党保守党和工党形成过两次共识 ,即社会民主主义共识和新自由主义共识。两党共识政治的主要特征是政策的共性与差异性并存 ,其中 ,差异不是根本性的 ,共性是共识政治的主要方面。两党共识的根源在于对某一共同的政治框架的接受 ,两党差异的根源在于政党性质、传统的不同及出于对执政未来的考虑。

企业职工创造发明教育内容初探

在企业职工教育中,开设创造发明课程是提高职工创造力的最佳途径。该课程涉及的内容应包括:树立创新意识,培养创造精神;培养发明技巧,传授创造技法;选择发明课题,实践发明技法;讲授知识产权常识,鼓励职工申请专利。     

《合汗衫》元本与臧本异同论

元人张国宾所作《公孙汗衫记》与臧懋循收入《元曲选》的《合汗衫》在情节内容上大体一致,但在科白的有无及详略上却截然不同。差异的产生,与元人重曲轻白,以曲为剧,而明人曲白兼取,重案头之剧的戏剧观念有着密切关系。     

高光谱遥感影像中光谱向量编码方法的研究

Taking into account the demands of hyperspectral remote sensing (RS) image retrieval and processing, some encoding methods of spectral vector including direct encoding, feature-based encoding and tree-based encoding methods are proposed and compared. In direct encoding, based on the analysis of binary encoding and quad-value encoding, decimal encoding is proposed. It is proved that quad-value encoding and decimal encoding are suitable to fast processing and retrieval. In absorption feature-based encoding method, five common metrics are compared. Because locations of reflection/absorption features are sensitive to noise, this method is not very effective in retrieval. In tree-based encoding methods, bitree, quadtree, octree and hextree are proposed and discussed. It is proved that 2-level octree and 2-level hextree are more effective than bitree and quadtree. Finally, quad-value encoding, decimal encoding, 2-level octree and 2-level hextree are proposed in spectral vectors encoding, similarity measure and hyperspectral RS image retrieval.
