✦ Synopsis

We briefly analyze some characteristics of the behavior in very shallow waters i.e. near the shoreline of high-order (dispersive-nonlinear) Boussinesq-type equations. By using the Carrier and Greenspan (1958) solution as test flow conditions we illustrate the behavior of both purely dispersive and dispersive-nonlinear contributions near the shoreline. It is also shown that Boussinesq-type equations can be more usefully handled in the swash zone if written in terms of the total water depth.

In this paper, we consider the two-dimensional Newton-Boussinesq equations with the incompressibility condition. We obtain a regularity criterion for the Newton-Boussinesq equations by virtue of the commutator estimate.

## Abstract The goal of Consumer Psychology is to use manipulations and measures in order to make inferences as to the psychological processes that underlie consumer behavior. A statistical tool available to do so is Structural Equation Modeling (SEM). Recent issues of this journal have provided pr
