Body mass index as a standard of living measure: a different interpretation for the case of Colombia

We analyze the Body Mass Index (BMI) in a distinct way of its traditional use and it lets us use it as a proxy of standard of living for the case of Colombia. Our approach is focused on studying how far the people are from the normal range and not on the score of each one and this lets us to treat equally extreme cases as severe thinness and obesity. We use a probabilistic model (Ordered Probit) that evaluates the probability of being within the normal range or another level. We found that socioeconomic variables have a significant effect on the dependent variable and that there are no linear effects. Besides, people with difficulties for walking and adults have less probability of having a normal BMI.

The impact of the direct foreign investment in Colombia

La inversión extranjera directa en Colombia es un asunto que particularmente desde 1990 ha venido tomando fuerza y que a su vez genera múltiples cuestiones. Para abordar el impacto que la IED ha tenido en Colombia se hace necesario hacer un acercamiento teórico para comprender el concepto, pasando por el estudio del caso latinoamericano para después seleccionar los principales sectores de la economía colombiana y en los cuales la IED ha jugado un rol destacado, como es el caso del sector financiero, la industria manufacturera, el sector de electricidad, gas y agua, el sector de transporte, almacenamiento y comunicaciones y el sector petróleo. Con ello en mente será posible establecer y medir el impacto económico de la IED, tomando como principal indicador la correlación entre la IED y PIB por sector y otros aspectos como el impacto en el empleo y la transferencia de conocimiento y tecnología. Igualmente es necesario abordar la perspectiva del inversionista y los riesgos y beneficios que corre al invertir en Colombia, esto permitirá ampliar el campo de análisis y establecer otras relaciones e impactos conexos de la IED en los aspectos sociales y culturales del país. Gracias a estos análisis será posible emitir un juicio de valor sustentado en un análisis científico detallado sobre el verdadero impacto de la IED y extendiéndose más allá del campo económico.

Dilemmas in Regards to the Restitution of Lands in Colombia

The text argues that, even if different sectors of society have some strategic points of agreement on the issue of land, which converge on the specific issue of restitution, they strongly disagree on various other points. On one side are some who advocate “pure restitution” and consequently support a restitution policy that focuses on correcting the illegal dispossession and clarifying land titles and individual rights to property, which would serve to boost the land market and allow for rural development policies that modernize agricultural production, fundamentally based on large, corporate ownership. On the other end of the spectrum are advocates of what we call “comprehensive restitution,” who promote adopting a restitution policy that meets the requirements not only of corrective justice but also of recognition and redistribution, advancing the interest of peasant, indigenous, and afro-Colombian communities.

Contribution from neuropsychology to the study of semantic memory

Semantic memory has been studied from various fields. The first models emerged from cognitive psychology from the hand of the division proposed by Tulving between semantic and episodic memory. Over the past thirty years there have been parallel developments in the fields of psycholinguistics, cognitive psychology and cognitive neuropsychology. The present work is to review the contributions that have emerged within the neuropsychology to the study of semantic memory and to present an updated overview of the points of consensus. First, it is defined the term "semantics" conceptually within the field of neuropsychology. Then, there is a dichotomy that passes through both psychological and neuropsychological models on semantic memory: the existence of modals versus amodal representations. Third, there are  developed the main theoretical models in neuropsychology that emerged in an attempt to explain categoryspecific semantic deficits. Finally, more robust contributions and points that still generate some discussion are reviewed.

The determinants of the health status in a developing country: results from the Colombian case

El artículo busca encontrar evidencia empírica de los determinantes de la salud, como una medición de capital salud en un país en desarrollo después de una profunda reforma en el sector salud. Siguiendo el modelo de Grossman (1972) y tomando factores institucionales, además de las variables individuales y socioeconómicas. Se usaron las encuestas de 1997 y 2000 donde se responde subjetivamente sobre el estado de salud y tipo de afiliación al sistema de salud. El proceso de estimación usado es un probit ordenado. Los resultados muestran una importante conexión entre las variables individuales, institucionales y socioeconómicas con el estado de salud. El efecto de tipo de acceso al sistema de salud presiona las inequidades en salud.
