This paper develops a ridge procedure for structural equation modelling (SEM) with ordinal and continuous data by modelling the polychoric/polyserial/product-moment correlation matrix R. Rather than directly fitting R, the procedure fits a structural model to R(a) =R+aI by minimizing the normal distribution-based discrepancy function, where a > 0. Statistical properties of the parameter estimat...

In this paper we give worked examples of adding national data to international datasets in order to add value to the secondary analysis of this data. We also show how more sophisticated techniques, including multilevel modelling and structural equation modelling, can be applied to such enhanced data to go beyond the potentially misleading simple correlational analysis. The paper is illustrated ...

As a service organization, for an academic institution, knowledge sharing is a critical process that needed to be done and developed always in order to achieve sustainable advantage, emphasizing its role as center of excellence. The research objection was to explore the relationship between the three constructs: Knowledge Sharing, Absorptive Capacity and Channel Richness. The conceptual and str...

The impact assessment method seeks to bring about a more ecologically, socio-culturally and economically sustainable and equitable environment. Determining the main factors affecting the attitudes of stakeholders is crucial for understanding the impacts of development plans. This approach helps planners and decision makers to identify the values and traits of stakeholders and accelerate the dif...

Introduction. This study examines the structure of Web space in the field of library and information science using multivariate analysis of social tags from the Website, Delicious.com. A few studies have examined mathematical modelling of tags, mainly examining tagging in terms of tripartite graphs, pattern tracing and descriptive statistics. This study is one of the few studies to employ multi...

The factor structure and construct validity of a Spanish version of Spector, Carey, and Steinberg's Sexual Desire Inventory was examined with structural equation modelling and a nonclinical sample (N = 608). Confirmatory factor analysis indicated that Dyadic and Solitary sexual desire scales measured two factorially distinct constructs. Their internal consistency reliabilities were .87 and .88,...
