The constructive replication of a prespecified, cognitively mediated model of rape’s impact on psychosocial health is reported using longitudinal data (see Koss, Figueredo, & Prince, 2002, for a summary of model development). Rape survivors (n = 59) were assessed four times, 3 to 24 months postrape. Structural equations modeling of baseline data (intercepts) and rate of change over time (slopes...

We study a nonlinear, unsteady, moving boundary, fluid–structure interaction (FSI) problem in which the structure is composed of two layers: a thick layer, and a thin layer which serves as a fluid–structure interface with mass. The fluid flow, which is driven by the time-dependent dynamic pressure data, is modeled by the Navier–Stokes equations for an incompressible, viscous fluid, defined on a...

We look more carefully at the modeling of causality using structural equations. It is clear that the structural equations can have a major impact on the conclusions we draw about causality. In particular, the choice of variables and their values can also have a significant impact on causality. These choices are, to some extent, subjective. We consider what counts as an appropriate choice. More ...

some believe that there is always a link between happiness and an individual health. this paper addresses a research question as: how does a leader’s spiritual beliefs and spiritual practices affects on happiness as perceived by ones followers. in this study, it was constructed an original model to carry out a research analysis at some universities in isfahan. the main objective of the research...

In a simple model composed of a structural equation and identity, the finite sample distribution of the IV/LIML estimator is always bimodal and this is most apparent when the concentration parameter is small. Weak instrumentation is the energy that feeds the secondary mode and the coefficient in the structural identity provides a point of compression in the density that gives rise to it. The IV...
