Ronce and Kirkpatrick (2001) derived the model on which our first model (eqq. [1], [2]) is based, and our equation for evolution is identical to theirs. Our ecological model differs because we include nonlinear density dependence and mortality due to predation. It is useful to express the ecological model in terms of more familiar ecological and evolutionary parameters to point out a difference...

BACKGROUND There are several evaluation models that can be used to evaluate the effect of in-service training; one of them is the Kirkpatrick model. The aim of the present study is to assess the in-service training of cardiopulmonary resuscitation (CPR) for nurses based on the Kirkpatrick's model. MATERIALS AND METHODS This study is a cross-sectional study based on the Kirkpatrick's model in ...

Abstract. We introduce a Sherrington-Kirkpatrick spin-glass model with the addition of elastic degrees of freedom. The problem is formulated in terms of an effective four-spin Hamiltonian in the pressure ensemble, which can be treated by the replica method. In the replica-symmetric approximation, we analyze the pressuretemperature phase diagram, and obtain expressions for the critical boundarie...
