Structural equation modeling (SEM) has dominated causal analysis in the social and behavioral sciences since the 1960s. Currently, many SEM practitioners are having diiculty articulating the causal content of SEM and are seeking foundational answers. Recent developments in the areas of graphical models and the logic of causality show potential for alleviating such diiculties and thus for revita...

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 ...

Meeting satisfaction is an important construct to the field of research on group support systems (GSS). This is because unless the use of GSS technology produces an increase in meeting satisfaction, it is unlikely that users will seek to adopt the technology, regardless of any productivity gains that might be realized. If the underlying causes of meeting satisfaction can be identified, then res...

In the behavioral and social sciences, structural equation models (SEMs) have become widely accepted as a modeling tool for the relation between latent and observed variables. SEMs can be seen as a unification of several multivariate analysis techniques. SEM Trees combine the strengths of SEMs and the decision tree paradigm by building tree structures that separate a data set recursively into s...

The probabilistic approach to the evaluation of fire hazard and the effectiveness of fire-precaution measures enables a rational response to the randomness of fire outbreaks. This article employs the statistical analysis methods to elucidate the causes for the ignition of fire on a random sample of industrial buildings in the Republic of Slovenia. The analyses are based on the Structural Equati...

Despite the popularity of online auctions as a new e-commerce operating model, few studies have explored why sellers intend to pay for the services of particular auction sites, especially while other free auction services exist. Developed on the basis of the theory of perceived value, this study includes network externalities in seller perceptions and explores why sellers intend to pay for thes...

The present study tested a causal model of Internet piracy among university’s students using a structural equation modeling (SEM) procedure. Using a sample of 116 university students, the relationships among habit, affect, intention, and actual behavior towards Internet piracy were tested. The results showed that habit has a strong effect on Internet piracy behavior. The results also revealed t...
