Estimation of generalized linear latent variable models

Summary.  Generalized linear latent variable models (GLLVMs), as defined by Bartholomew and Knott, enable modelling of relationships between manifest and latent variables. They extend structural equation modelling techniques, which are powerful tools in the social sciences. However, because of the complexity of the log-likelihood function of a GLLVM, an approximation such as numerical integration must be used for inference. This can limit drastically the number of variables in the model and can lead to biased estimators. We propose a new estimator for the parameters of a GLLVM, based on a Laplace approximation to the likelihood function and which can be computed even for models with a large number of variables. The new estimator can be viewed as an M -estimator, leading to readily available asymptotic properties and correct inference. A simulation study shows its excellent finite sample properties, in particular when compared with a well-established approach such as LISREL. A real data example on the measurement of wealth for the computation of multidimensional inequality is analysed to highlight the importance of the methodology.     

LISREL与PLS路径建模原理分析与比较

1LISR EL建模原理分析狭义上讲,结构方程建模(SEM)多指线性结构关系模型LISREL(linear Structural R ELationship)。LISR EL这个名称有两个含义,一是由JO¨reskog熏提出的线性结构方程式模型,它是协方差结构模型分析的典型代表;二是表示由JO¨reskog和其合作者SO¨rbom共同开发     

EXPLORING LINKAGES BETWEEN MANUFACTURING STRATEGY,BUSINESS STRATEGY,AND ORGANIZATIONAL STRATEGY

In recent years there has been an increased emphasis on the development of manufacturing and business strategies. In spite of that high level of emphasis, limited empirical research has been published on the linkage between manufacturing strategy, business strategy, and organizational performance. Our study examines that linkage. Our main contribution lies in (i) building constructs for some important elements of manufacturing strategy and business strategy and (ii) testing the impact of linkage between manufacturing strategy and business strategy on organizational performance. The study is based on 175 responses from senior executives in manufacturing organizations.     

线性结构方程模型的原理及其实际应用

线性结构方程模型（ＬＩＳＲＥＬ）是近几十年来新发展的一种统计方法,并广泛地应用于社会科学研究的各个领域。文章阐述了这种统计方法的基本原理及其在实际中的应用,并详尽地介绍了与其他常用的统计方法比较这种方法的主要优点。     

关于顾客满意度指数的若干问题研究

GDP指标在为人们提供衡量经济发展数量的客观手段的同时 ,也逐渐淡化了经济发展是为人类生活更加幸福的初衷。然而人类幸福本身终究是社会进步的驱动因素和终极目的 ,当人们重新审视这一简单的哲学命题的时候 ,再也不能容忍GDP独自垄断经济评价的发言权 ,必须有一个令人信服的声音 ,来评价经济资源的产出质量。顾客满意 (CS .CustomerSatisfaction) ,是指顾客通过对一个产品或服务的感知效果 /结果与其期望值相比较后 ,所形成的愉悦或失望的感觉状态。顾客满意度就是顾客满意水平的量化 ,正是从人作为消费者的角度 ,来衡量产出质量的。…     

基于LISREL的社区服务公众满意度测评研究

社区服务是在改革开放中发展起来的新兴产业,随着城市建设的发展和城市管理体制的改革,社区在城市建设中的基础地位愈益显著,社区功能明显增强,社区服务日益成为公众关注的焦点。提高社区服务公众的满意度,对于提高社区居民生活质量、化解社会矛盾、促进和谐社会建设都具有重要意义。本文即以顾客满意理论为基础,构建了社区服务公众满意度指数模型,并以实证研究验证了模型的合理性。     

物流绩效的衡量方法

1物流绩效衡量主要指标物流控制的目标是跟踪作业计划与实绩之差,以识别提高效率和效益的机会。尽管传统的物流衡量在功能领域仍有应用前景,但在今日的竞争环境中,有一个方向正在越来越受到人们的重视。这个方向是考虑完成客户订单所需的总成本,从而可以更有效地识别和评估代价     

Reflexivity in the Research Process: Psychoanalytic Observations

This paper highlights what psychoanalysis can add to discussions of reflexivity, by specifically describing how reflexivity is conceptualized and fostered on psychoanalytic observation methods courses at the Tavistock Clinic, London. It is demonstrated that this psychological form of reflexivity is relevant to empirical and conceptual work and shown that it shares interesting parallels with debates about reflexivity in social research methods, while also being able to contribute to discussions of what constitutes reflexivity and what kinds of methods course might facilitate it. Reflexivity is often discussed in relation to a researcher’s empirical work, but this paper argues that reflexivity is equally needed in relation to the academic context in which most research and learning takes place. This paper demonstrates how psychoanalytic approaches to learning stimulate a reflexive relation to empirical and conceptual work and it provides examples of reflexivity from a two‐year infant observation and a research project on romantic love (involving conceptual and biographical research).     

Accounting and Market-Value Measures of Profitability: Consistency,Determinants, and Uses

This study examines the relationship between accounting and market-value measures of profitability for individual firms. Differences in measures of profitability are observed both between and within industry groups and thus cannot be explained by differences in uncontrolled industry-specific influences. We suggest that both accounting and market can be used as unique but imperfect indicators of profitability. Using a LISREL model approach, we find R & D intensity, television advertising intensity, leverage, and industry growth to be important determinants of firm profits.     

华人文化与团队领导的管理认知--一项基于线性结构方程模型的实证研究

在相关研究的基础上,利用因素分析方法,研究了华人组织中团队领导的文化结构及其组织管理认知结构;同时,利用线性结构化相关分析(LISREL)的建模方法,实证了文化对团队领导管理认知结构的影响及组织管理认知各因素间的相关关系.认为,在华人组织中,文化是影响团队领导者管理认知的重要因素,基层团队领导的和谐倾向和群体倾向,是团队管理者内部控制的主要正向解释因素,而华人文化中的等级倾向,则对团队领导者的外部协作倾向有一定的负面影响.另外,企业层领导的文化倾向和管理认知与基层团队领导的文化与管理认知存在相似性的实证结果,也是华人企业中,家族主义文化倾向是存在的证据之一.
