Natural disasters and clientelism: the case of floods and landslides in Colombia

What are the effects of natural disasters on electoral results? Some authors claim that catastrophes have a negative effect on the survival of leaders in a democracy because voters have a propensity to punish politicians for not preventing or poorly handling a crisis. In contrast, this paper finds that these events might be beneficial for leaders. Disasters are linked to leader survival through clientelism: they generate an in-flow of resources in the form of aid, which increase money for buying votes. Analyzing the rainy season of 2010-2011 in Colombia, considered its worst disaster in history, I use a difference-in-differences strategy to show that in the local election incumbent parties benefited from the disaster. The result is robust to different specifications and alternative explanations. Moreover, places receiving more aid and those with judicial evidence of vote-buying irregularities, are more likely to reelect the incumbent, supporting the mechanism proposed by this paper.

Perfil acido-base de pacientes con cirrosis descompensada por hemorragia digestiva alta en el departamento de emergencias: serie de casos

Introducción: La hemorragia digestiva (HVDA) es la principal causa de descompensación en pacientes con cirrosis. Caracterizar el estado ácido-base de estos pacientes sería útil para reflejar la severidad del sangrado e identificar pacientes con alto riesgo de complicación. Objetivo: Describir el estado ácido-base de los pacientes que consultaron a urgencias con cirrosis descompensada por HVDA y posteriormente fueron manejados en la unidad de cuidado intensivo (UCI) o fallecieron. Métodos: Se realizó el análisis del estado ácido-base a 10 pacientes con estas características, utilizando tres métodos distintos. Resultados: El perfil ácido-base encontrado fue: acidosis metabólica por iones no medidos, acidosis láctica, alcalosis por hipoalbuminemia y anión gap elevado en la mayoría de pacientes. Conclusiones: La teoría de Henderson-Hasselbach no fue suficiente para identificar pacientes con alto riesgo, debería implementarse concomitantemente el análisis anión gap, base déficit y el método físico–químico, para entender los fenómenos acido base de estos pacientes.

C. Wright Mils revisited: Society and Power

C. Wright Mills has been forgotten by sociological theories however there is no doubt about how much he contributed to the field of Epistemology. He successfully participated in the American Sociology of Knowledge and, at the same time, he  upheld the tradition of the Conflict Theory, including the sociological dimension into one of the most questioned political subjects of his period. Undoubtedly,  Wright Mills was morally committed to the value of reason and freedom. His central issue was to analyse the real possibilities for a particular individual within  a particular social order to become a free man capable of reasoning. He wondered how someone could be able to transcend his daily nature through reason and  experience and to act accordingly to his power. The power and political processes were constant in his works, since he claimed that any political process was a  struggle for power and prestige, for authoritative positions, both within each nation  and among the different states. On the other hand, he  bserved that the social  structure in the United States of America was not completely democratic, since the  course of action depended on the decision of a small group of wealthy, powerful individuals. These concentrating spaces of power amongst some economic, military  and political corporations were supported by their underlying ideology, a fact that became clearer when referring to international affairs. Nowadays, in a world of  structural antagonisms, wars and rebellions, the need for looking at the work  of intellectuals like Mills re-emerges. Mills showed us a way in which a complex entity as power can be understood, and, at the same time, the need to consider the  course of history, its mechanics and process.

Comparación de cambios clínicos y hemodinámicos en pacientes con insuficiencia venosa mixta según tipo de manejo.

Existen varias causas de la insuficiencia venosa profunda, la insuficiencia venosa superficial es una de ellas; por tal motivo, una intervención activa de la insuficiencia superficial ya sea cirugía convencional, esclerosis o radiofrecuencia mejora el reflujo del sistema venoso profundo. En nuestro medio no se acostumbra a intervenir los pacientes con insuficiencia venosa mixta bajo la creencia de exacerbar la enfermedad o generar complicaciones. Se pretende documentar los cambios clínicos y hemodinámicos en pacientes con insuficiencia venosa mixta según tipo de manejo, médico vs quirúrgico
