Este estudio tuvo como objetivo determinar el efecto del tipo de violencia de que son víctimas las mujeres por parte de su pareja y sus esquemas cognitivos en el nivel del cortisol. Para ello se aplicó una versión traducida de la Encuesta de Severidad de Violencia en contra de la Mujer, la forma corta del Cuestionario de Esquemas Cognitivos de Young y se extrajeron muestras de cortisol plasmático diurno a 43 mujeres participantes en un programa de intervención. Se estructuró un modelo de regresión el cual confirmó que las amenazas, las agresiones sexuales y esquemas cognitivos como Abandono, Aislamiento social, Apego, Fracaso, Vulnerabilidad al Daño, Subyugación y Estándares Inflexibles, afectaron el nivel del cortisol de esta población.

A scheduling problem commonly observed in the metal working industry has been studied in this research effort. A job shop equipped with one batch processing machine (BPM) and several unit-capacity machines has been considered. Given a set of jobs, their process routes, processing requirements, and size, the objective is to schedule the jobs such that the makespan is minimized. The BPM can process a batch of jobs as long as its capacity is not exceeded. The batch processing time is equal to the longest processing job in the batch. If no batches were to be formed, the scheduling problem under study reduces to the classical job shop problem with makespan objective, which is known to be nondeterministic polynomial time-hard. A network representation of the problem using disjunctive and conjunctive arcs, and a simulated annealing (SA) algorithm are proposed to solve the problem. The solution quality and run time of SA are compared with CPLEX, a commercial solver used to solve the mathematical formulation and with four dispatching rules. Experimental study clearly highlights the advantages, in terms of solution quality and run time, of using SA to solve large-scale problems.
