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...

introduction: conflict is inevitable in intimate relationship in the form of disagreements, dislikes, arguments and tensions. it may result in the renovation if handled properly or deterioration of relationship if managed poorly. the aim of this descriptive- correlation study was to investigate the effects of marital coping strategies, personality and self-control on the marital conflict in a p...

Sediment flushing of reservoirs is an operational technique, whereby previously accumulated sediments in the reservoirs are hydraulically removed by accelerated flow when the bottom desiltingoutlets of the dam are opened. In this research, the process of sediment flushing is simulated by a three dimensional numerical model in which sediment and flow interaction are reflected in the reservoirs. ...

This study developed a structural equation model that investigates the hierarchical relationships among Big Five factors, impulsive buying and compulsive buying. It identified positive relationships between impulsive buying and compulsive buying, between emotional instability and the two traits, and between impulsive buying and two other personality traits (openness and extraversion).

Despite their popularity, many questions about the algebraic constraints imposed by linear structural equation models remain open problems. For causal discovery, two of these problems are especially important: the enumeration of the constraints imposed by a model, and deciding whether two graphs define the same statistical model. We show how the half-trek criterion can be used to make progress ...
