Ley de Víctimas de Colombia y la responsabilidad de las personas jurídicas por violaciones de derechos humanos

En el año 2011, después de cuatro años de cabildeo y forcejeo político, Colombia aprobó la Ley 1448, más conocida como la Ley de Víctimas. Los objetivos perseguidos por esta ley son bastante amplios, en la medida en que pretende ser una regulación comprensiva para enfrentar los efectos que el conflicto armado ha infligido en la población civil. En este sentido, la ley incluye las reformas legales que fueron consideradascomo necesarias para restablecer el estado de derecho a través de la proteccióny cumplimiento de los derechos de las víctimas. Actualmente, el gobierno, la sociedad civil y la academia se han enfocado en el análisis de los dilemas y grandes temas dela ley. Sin embargo, esta nueva regulación, con sus 208 artículos, es más amplia y compleja, razón por la cual es indispensable hacer un análisis más detenido de sus múltiples provisiones. Una de estas, que parece no haber llamado la atención y que, por lo tanto, no ha sido objeto de estudio pormenorizado es el artículo 46. A primera vista, este parece estar encaminado a reforzar la investigación y juzgamiento de las personas jurídicas relacionadas con violaciones de derechos humanos y derecho internacional humanitario en el contexto colombiano. Este texto examina específicamente los alcances reales y dilemas del artículo, y propone algunas soluciones para llenar la laguna que existe actualmente en el país en la materia.

Neurobiology of expectancy effects and omission of reinforcement on behavior

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.

Through meditation, people become aware of what happens in the body and mind, accepting the present experiences as they are and getting a better understanding of the true nature of things. Meditation practices and its inclusion as an intervention technique, have generated great interest in identifying the brain mechanisms through which these practices operate. Different studies suggest that the practice of meditation is associated with the use of different neural networks as well as changes in brain structure and function, represented in higher concentration of gray matter structures at the hippocampus, the right anterior insula, orbital frontal cortex (OFC) and greater involvement of the anterior cingulate cortex (ACC). These and other unrelated studies, shows the multiple implications of the regular practice of mindfulness in the structures and functions of the brain and its relation to certain observable and subjective states in people who practice it. Such evidence enabling the inclusion of mindfulness in psychological therapy where multiple applications have been developed to prove its effectiveness in treating affective and emotional problems, crisis management, social skills, verbal creativity, addiction and craving management, family and caregivers stress of dementia patients and others. However, neuropsychological rehabilitation has no formal proposals for intervention from these findings. The aim of this paper is to propose use of Mindfulness in neuropsychological rehabilitation process, taking the positions and theory of A.R. Luria.
