矛盾分析方法与系统分析方法的辩证思考

矛盾分析方法与系统分析方法之间具有辩证统一性,矛盾是有系统性的矛盾体,而系统则是包含着矛盾的系统。矛盾分析方法为系统分析方法提供指导,为系统分析方法的具体实施提供可能;系统分析方法是矛盾分析方法的丰富发展,为矛盾分析方法的运用作进一步的补充;矛盾分析方法与系统分析方法在实践中达到真正的统一。正确分析二者之间的内在联系,为我们进一步研究事物提供了新的视角。     

PLECS在电路分析中的应用

The analysis of negotiation of common ground in CSCL

CSCL research has given rise to a plethora of analysis methods, all with specific analysis goals, units of analysis, and for specific types of data (chat, threaded discussions, etc.). This article describes some challenges of CSCL-analysis. The development of an analysis method for negotiation processes in multidisciplinary teams serves as an example of how these challenges occur in practice. Results reveal a number of tensions with regard to establishing reliable coding procedures without compromising validity, such as how to define codes, and rules for applying codes. The discussion offers some guidelines for content analysis of CSCL-data.     

Analyzing Mixed-Dyadic Data Using Structural Equation Models

Mixed-dyadic data, collected from distinguishable (nonexchangeable) or indistinguishable (exchangeable) dyads, require statistical analysis techniques that model the variation within dyads and between dyads appropriately. The purpose of this article is to provide a tutorial for performing structural equation modeling analyses of cross-sectional and longitudinal models for mixed independent variable dyadic data, and to clarify questions regarding various dyadic data analysis specifications that have not been addressed elsewhere. Artificially generated data similar to the Newlywed Project and the Swedish Adoption Twin Study on Aging were used to illustrate analysis models for distinguishable and indistinguishable dyads, respectively. Due to their widespread use among applied researchers, the AMOS and Mplus statistical analysis software packages were used to analyze the dyadic data structural equation models illustrated here. These analysis models are presented in sufficient detail to allow researchers to perform these analyses using their preferred statistical analysis software package.     

A Tutorial in Bayesian Potential Outcomes Mediation Analysis

Statistical mediation analysis is used to investigate intermediate variables in the relation between independent and dependent variables. Causal interpretation of mediation analyses is challenging because randomization of subjects to levels of the independent variable does not rule out the possibility of unmeasured confounders of the mediator to outcome relation. Furthermore, commonly used frequentist methods for mediation analysis compute the probability of the data given the null hypothesis, which is not the probability of a hypothesis given the data as in Bayesian analysis. Under certain assumptions, applying the potential outcomes framework to mediation analysis allows for the computation of causal effects, and statistical mediation in the Bayesian framework gives indirect effects probabilistic interpretations. This tutorial combines causal inference and Bayesian methods for mediation analysis so the indirect and direct effects have both causal and probabilistic interpretations. Steps in Bayesian causal mediation analysis are shown in the application to an empirical example.

Rhetorical analysis in critical policy research

Rhetorical analysis, an approach to critical discourse analysis, is presented as a useful method for critical policy analysis and its effort to understand the role policies play in perpetuating inequality. A rhetorical analysis of Character Matters!, the character education policy of a school board in Ontario, Canada, provides an illustrative example of the method’s contributions to the field. I identify rhetorical appeals of Character Matters! texts that aim to persuade the policy’s audience to support a predominantly traditional approach to character education. I then present contributions of rhetorical analysis for critical policy research and possibilities of rhetorical analysis for democratizing policy processes. I conclude by considering possible implications for York Region if the rhetoric of Character Matters! successfully convinces its audience to support the traditional approach to character education it advocates.     

Exploring and testing cluster analysis

Academic deans annually negotiate for a fair share of university resources. Without quantitative accreditation standards to serve as minimum guidelines, the competition is more difficult. Peer institution comparison, derived from the analysis of quantitative data on resource and productivity variables, assists by providing less biased justification for budget requests. In this study, data from a national study of doctoral-granting teacher education programs was used for a factor analysis of key resource and productivity variables. Seven alternative cluster analysis methods were used and compared. Three follow-up procedures (analysis of variance, discriminant analysis, and classification analysis) tested the cluster analysis results to verify the differences between clusters and their internal homogeneity on three different cluster solutions. The classification analysis showed that 88.2% of the 76 programs were correctly classified on the five-cluster solution produced using Ward's minimum variance method. The practical use of such data suggests that Cattell's pattern of profile similarly is a useful beginning to compare programs on factor scores; following that, raw data on each key variable might be used to prepare individual program profiles for more specific comparison.
