A Solution to the Disconnect between Country Risk and Business Cycle Theories

We propose a model that solves the crucial disconnect between business cycle models that treat default risk as an exogenous interest rate on working capital, and sovereign default models that treat output fluctuations as an exogenous process with ad-hoc default costs. The model explains observed output dynamics around defaults, countercyclical spreads, high debt ratios, and key business cycle moments. Three features of the model are central for these results: working capital loans pay for imported inputs; default triggers an efficiency loss as imported inputs are replaced by imperfect domestic substitutes; and default on public and private foreign obligations occurs simultaneously.

A General Equilibrium Model of Sovereign Default and Business Cycles

Emerging markets business cycle models treat default risk as part of an exogenous interest rate on working capital, while sovereign default models treat income fluctuations as an exogenous endowment process with ad-hoc default costs. We propose instead a general equilibrium model of both sovereign default and business cycles. In the model, some imported inputs require working capital financing; default triggers an efficiency loss as these inputs are replaced by imperfect substitutes; and default on public and private obligations occurs simultaneously. The model explains several features of cyclical dynamics around defaults, countercyclical spreads, high debt ratios, and key business cycle moments.

Arte

El Departamento de Arte presenta en esta edición de UNIVERSITAS HUMANÍSTICA, un cuento de Mario Mendoza, escritor y catedrático. El relato moderno, a partir de Edgar Allan Poe, ha involucrado un alto nivel de "pathos", producto de una introspección muy aguda en el narrador, que busca atrapar y problematizar al lector. El crítico Jaime Alazraki ha utilizado el concepto de lo "neo-fantástico" para referirse a los trabajos de Julio Cortázar y Jorge Luis Borges, procurando definir esa manera de introducir el misterio, la alogicidad y la irracionaldad en la cotidianidad. Los relatos de Mario Mendoza, en su gran mayoría están inscritos en esta corriente de la literatura latinoamericana.Carolina IriarteDirectora Departamento de Art

Medical residents’ consumption of psychoactive substances, bogotá, 2001

A cross-sectional study was carried out to establish the prevalence of both legal and illegal psychoactive substance consumption in a population of medical and surgical resident students (193 subjects), from a university in Bogotá, and relate this to macro and micro social environmental factors. The instruments for data collection employed were the Epidemiological Surveillance System for Inadequate Use of Psychoactive Substances' (VESPA) questionnaire 1, and the alcohol consumption assessment scale (CAGE) to establish alcoholism and its risk. A 1% prevalence of illegal psychoactive substances was found and alcohol, coffee and cigarette consumption prevalence was 86.5%, 71.5% and 24.4%, respectively, which is similar to that found in the general population. The percentage of alcoholic students identified, according to the CAGE scale, was 5.2%, a much lower figure than that reported in other studies. The exploratory bi variable analysis was carried out by prevalence ratio; i.e. being aged between 24 and 28 years, being economically dependent on other people such as wife or husband, parents and/or brothers, having friends and relatives who get drunk and studying as a surgical resident were identified as risk factors for alcohol consumption to the point of drunkenness.Se realizó un estudio de corte transversal, con el fin de establecer la prevalencia de consumo de sustancias psicoactivas legales e ilegales en la población de estudiantes de especialidades medico quirúrgicas (193 sujetos) de una institución universitaria de Bogotá y relacionarla con factores del entorno macro y microsocial. Se utilizó como instrumento para recolectar la información el formulario uno del Sistema de Vigilancia Epidemiológica para Uso Indebido de Sustancias Psicoactivas-VESPA, y la escala de evaluación de consumo de alcohol-CAGE, para establecer alcoholismo y riesgo de alcoholismo. Se encontró que existe una prevalencia de consumo de psicoactivos ilegales del 1%, y prevalencias de consumo de alcohol, café y cigarrillo similares a los de la población general con prevalencias anuales de 86,5 %, 71,5 % y 24,4 % respectivamente. El porcentaje de estudiantes alcohólicos identificados según la CAGE fue del 5,2 %, cifra mucho menor a la encontrada en otros estudios. El análisis exploratorio bivariado se realizó por medio de razones de prevalencia y se identificaron como probables factores de riesgo para el consumo de alcohol hasta la embriaguez, las edades entre 24-28 y 29-38 años, la dependencia económica de otras personas como el esposa(o), los padres y/o hermanos, tener amigos y familiares que consumen  alcohol hasta la embriaguez y, pertenecer a una especialidad quirúrgica

OPT3 is a component of the iron-signaling network between leaves and roots and misregulation of OPT3 leads to an over-accumulation of cadmium in seeds.

Plants and seeds are the main dietary sources of zinc, iron, manganese, and copper, but are also the main entry point for toxic elements such as cadmium into the food chain. We report here that an Arabidopsis oligopeptide transporter mutant, opt3-2, over-accumulates cadmium (Cd) in seeds and roots but, unexpectedly, under-accumulates Cd in leaves. The cadmium distribution in opt3-2 differs from iron, zinc, and manganese, suggesting a metal-specific mechanism for metal partitioning within the plant. The opt3-2 mutant constitutively up-regulates the Fe/Zn/Cd transporter IRT1 and FRO2 in roots, indicative of an iron-deficiency response. No genetic mutants that impair the shoot-to-root signaling of iron status in leaves have been identified. Interestingly, shoot-specific expression of OPT3 rescues the Cd sensitivity and complements the aberrant expression of IRT1 in opt3-2 roots, suggesting that OPT3 is required to relay the iron status from leaves to roots. OPT3 expression was found in the vasculature with preferential expression in the phloem at the plasma membrane. Using radioisotope experiments, we found that mobilization of Fe from leaves is severely affected in opt3-2, suggesting that Fe mobilization out of leaves is required for proper trace-metal homeostasis. When expressed in yeast, OPT3 does not localize to the plasma membrane, precluding the identification of the OPT3 substrate. Our in planta results show that OPT3 is important for leaf phloem-loading of iron and plays a key role regulating Fe, Zn, and Cd distribution within the plant. Furthermore, ferric chelate reductase activity analyses provide evidence that iron is not the sole signal transferred from leaves to roots in leaf iron status signaling

Simulation of Flow of Mixtures Through Anisotropic Porous Media using a Lattice Boltzmann Model

We propose a description for transient penetration simulations of miscible and immiscible fluid mixtures into anisotropic porous media, using the lattice Boltzmann (LB) method. Our model incorporates hydrodynamic flow, diffusion, surface tension, and the possibility for global and local viscosity variations to consider various types of hardening fluids. The miscible mixture consists of two fluids, one governed by the hydrodynamic equations and one by diffusion equations. We validate our model on standard problems like Poiseuille flow, the collision of a drop with an impermeable, hydrophobic interface and the deformation of the fluid due to surface tension forces. To demonstrate the applicability to complex geometries, we simulate the invasion process of mixtures into wood spruce samples.Comment: Submitted to EPJ
