The reinforcement omission effects have been traditionally interpreted in terms of: behavioral facilitation after reinforcement omission induced by primary frustration or behavioral suppression after reinforcement delivery induced by postconsummatory states. The studies reviewed here indicate that amygdala is involved in modulation of these effects. However, the fact that amygdala lesions, extensive or selective, can eliminate, reduce and enhance the omission effects makes it difficult to understand how it is the exact nature of their involvement. The amygdala is related to several functions that depend on its connections with other brain systems. Thus, it is necessary to consider the involvement of a more complex neural network in the modulation of the reinforcement omission effects. The connection of amygdala subareas to cortical and subcortical structures may be involved in this modulation since they also are linked to processes related to reward and expectancy.

El nacimiento de un hijo o una hija constituye un momento transcendental en la vida personal y familiar, en el que se desarticulan o consolidan aspectos de la feminidad y la masculinidad. Objetivo: desde esta perspectiva se realizó una investigación con el fin de comprender la formacomo influyen la representación de la maternidad, el sistema médico en el que se inserta la atención al parto y las legislaciones relacionadas con la maternidad en la concepción y en el ejercicio de la maternidad y la paternidad durante el embarazo, el parto y el puerperio. Metodología: se utilizaron varias técnicas cualitativas de investigación (entrevistas y observación participante) a mujeres atendidas en tres hospitales de maternidad de La Habana y sus compañeros (esposos legales o consensuales). Resultados: los hallazgos develan roles de género en los cuales la mujeres la cuidadora por excelencia y la responsable de la reproducción y los hombres son relegados de ella; se refuerzan y consolidan institucionalmente desde lo legislado y desde la atención médica al proceso. Paralelo a esto, deja al descubierto la emergencia de una nueva masculinidad mediante la mayor implicación de los hombres en este proceso, de su mayor inserción en el espacio privado y de la exteriorización de sentimientos asociados con el nacimiento de su bebé. Conclusión: surge la necesidad de generar políticas orientadas a desmontar la cultura patriarcal en aras de construir relaciones de pareja más igualitarias y democráticas en la sociedad cubana.

The urban growth in Latino American cities, in a neoliberal context, has led to several population groups to having no possibilities to the access to urban land. Informal and irregular urban settlements increase, requiring attention from local governments, with actions and strategies in order to achieve both the regularization of such situation and further prevention. In the city of Córdoba different informal and irregular operations have taken place promoted by different actors. Furthermore, policies focused on regularization which have been promoted, have few intervention mechanisms, a fact that becomes critical, especially for the urban problems it causes. The main aim of this article is to present a classification over different modes of urban land acquirement taking place out of both urban and civil legislations. Afterwards, different informal settlement typologies are described, as well as the policies focused on them, together with their respective effects and impacts.
