My aim in this paper is to propose a reflection on the position and the importance that the constitutional judge has in the legal systems of contemporary constitutionalism. The figure of the judge responsible of protecting the Constitution is a key institution, without which we cannot understand the laws of constitutional democracies, their current lines of development, and the guarantee of rights and freedoms that constitute the normative core of these systems. Moreover, the reflection on the exercise of the powers of the judge, its scope and its justification is an important part of contemporary legal discussion, still relevant, albeit not exclusively - in the field of legal philosophy. The object of attention of my reflection is the judge who has the power of judicial review, in a scheme of defense of the Constitution, regardless the specific ways of this defense.

Esta monografía tiene como objetivo analizar los efectos de la transferencia de ayuda internacional para el desarrollo en el proceso de consolidación de Somalia. Dicha ayuda surgió como política pública en el contexto de la Guerra Fría y su instrumentalización dependió de los conflictos e intereses de las potencias de la época. En la década de los 60, Somalia fue receptora de millones de dólares en ayuda, que minaron el proceso de state-building dado que las transferencias no dependieron del desempeño económico, social ni político del Estado. El cual, dirigido por el General Barre, se convirtió en un ente cuyo único fin era la captación de la ayuda y cuyo control era la única forma de asegurar la supervivencia física. Los enfrentamientos entre clanes por el poder llevaron no sólo al colapso del Estado, sino también al surgimiento del período de anarquía más largo conocido por un Estado moderno.

La presente monografía tiene como objetivo explicar el papel de las sanciones y discursos de Estados Unidos, la Unión Europea e Israel frente al Programa Nuclear Iraní en la redefinición de la identidad de la República Islámica. En este sentido, se defenderá que las acciones punitivas emprendidas por las potencias mencionadas, han incidido en la auto-comprensión de la identidad nacional de Irán al reafirmar su carácter revisionista con la identificación por parte de las potencias, de los valores de la República Islámica con una amenaza para la seguridad regional e internacional. Para comprobarlo, se utilizará el concepto de identidad y de proceso de interacción simbólica, propios del enfoque constructivista. Así mismo, será necesario realizar un diseño documental e histórico, realizando de esta manera un análisis explicativo y analítico de los discursos de los líderes tanto de las potencias que se oponen al Programa Nuclear como de la controversial República Islámica.

La Justicia Penal Militar es el privilegio histórico más importante que ha sido concedido a las Fuerzas Militares colombianas debido a la función pública que desempeñan. De allí, que la presente investigación esté dirigida a comprender las causas que han conducido a que el Fuero Militar sea una figura cada vez más restringida no sólo en el mundo, sino en Colombia. Así mismo, el papel de las víctimas será transcendental en el trabajo para comprender un proceso de deslegitimación de la institución marcial traducido en la generación de un debate nacional en torno a la conveniencia de la ampliación de las competencias judiciales de su jurisdicción especial. Finalmente, se planteará una posible alternativa a partir de la conceptualización sobre la Justicia elaborada por John Rawls en el siglo XX, con miras solventar este fenómeno político, jurídico y social.

Este trabajo es una revisión de literatura que abarca una serie de artículos disponibles en la base de datos de la Universidad del Rosario, publicados entre los años 2006- 2016. En total se revisaron 52 artículos. Se presenta el concepto de sublimación según el psicoanálisis, el cual ha sido investigado en áreas como la religión, la filosofía, el arte, la cultura y en algunos casos en donde este se evidencia; finalmente se presentan conclusiones sobre dicho concepto durante últimos 10 años.

We analyze the effect of a parametric reform of the fully-funded pension regime in Colombia on the intensive margin of the labor supply. We take advantage of a threshold defined by law in order to identify the causal effect using a regression discontinuity design. We find that a pension system that increases retirement age and the minimum weeks during which workers must contribute to claim pension benefits causes an increase of around 2 hours on the number of weekly worked hours; this corresponds to 4% of the average number of weekly worked hours or around 14% of a standard deviation of weekly worked hours. The effect is robust to different specifications, polynomial orders and sample sizes.

The purpose of this article is to analyze the coverage made by CNN and Al Jazeera (in Arabic) to operation Caste Lead and the Goldstone Report during 2008 and 2009. This investigation is based in the theory of Qualitative Analysis of Content, by Wildemuth and Zhang. The methodology follows up with the one proposed by the authors in the main theory, complementing it with the Gamson and Modigliani´s Framing theory. The methodology mention above display the different in the coverage development, determined by the geopolitical influences; being CNN more influenced by a Western pro USA and pro Israeli speech, while Al Jazeera is more prone to support the Palestinian cause, this is the thesis of this article. During the development of the investigation, the thesis was demonstrated to be only partially accurate as CNN was not completely supportive to the Israeli arguments during the coverage, but Al Jazeera did have preferential speech for the Palestinian cause.

Dengue and Chikungunya viruses cause the most important arthropod-borne viral infections for humans. These viruses are predominant in tropical and subtropical regions. In addition, these viruses are predominant in tropical and subtropical regions. Dengue mortality rate is around 1.2 to 3.5% and deaths due to chikungunya fever are around 1 in 1000; however, half of chikungunya-infected patients evolve into a chronic state that can persist for months up to years. There are no antiviral drugs available for DENV and CHIKV treatment and prevention. Moreover, vector control strategies have failed so far. Thus, the development of potent inhibitors for a broad spectrum of RNA viruses is urgently needed. We established and characterized a new embryonic insect cell line from Culex quinquefasciatus mosquito. Also we established the flaviviruses and alphavirus replication, both in C6/36 and Lulo insect cell lines, as well as in Vero cell line. In addition we carried out a reference compound library and reference panel of assays and data for DENV, which provides a benchmark for further studies. During this study, a panel of 9 antiviral molecules, with proven in vitro anti-dengue virus activity and that act at different stages of the DENV life cycle, was selected. Finally, Favipiravir or T-705, was identified as inhibitor in vitro and in vivo of alphaviruses and the mutation K291R in nsP4, which is responsible of the polymerase activity, was found as the mode of action in CHIKV. Interestingly, lysine in motif F1 is also highly conserved in positive-stranded RNA viruses and this might explain the broad spectrum of T-705 antiviral activity.

In this paper we use the most representative models that exist in the literature on term structure of interest rates. In particular, we explore affine one factor models and polynomial-type approximations such as Nelson and Siegel. Our empirical application considers monthly data of USA and Colombia for estimation and forecasting. We find that affine models do not provide adequate performance either in-sample or out-of-sample. On the contrary, parsimonious models such as Nelson and Siegel have adequate results in-sample, however out-of-sample they are not able to systematically improve upon random walk base forecast.
