Lipoinyección laríngea en el tratamiento de parálisis vocal

Introducción. La parálisis de pliegue vocal unilateral constituye una de las causas de incompetencia glótica, presentando síntomas como disfonía, tos crónica, aspiración y fonastenia, afectando de forma significativa el desempeño y calidad de vida del paciente. Según las diversas corrientes de trabajo se ha manejado esta patología con terapia vocal como coadyuvante en opciones quirúrgicas como la laringoplastia de inyección. Objetivo. Realizar seguimiento clínico de pacientes con parálisis vocal unilateral que consultan al Hospital Universitario de la Samaritana centro de referencia de III nivel de Cundinamarca. Materiales y Métodos. Se toma una población de 36 pacientes aleatorizados en dos grupos cuyas intervenciones son manejo con terapia vocal (conservador) y laringoplastia de inyección con grasa. Resultados. Cierre glótico postratamiento mayor en el grupo de intervención médica con terapia vocal ( promedio 10-20 sesiones ) donde se logró un cierre completo en el 77,8% de los pacientes comparado con 33,3% en el grupo de intervención quirúrgico . Conclusión. Es preciso realizar detección temprana, establecer la etiología en nuestra población e instauración de una terapéutica oportuna como el manejo conservador con terapia vocal para disminuir los malos hábitos fonatorios adoptados por estos pacientes, establecer un manejo adecuado para mejorar los síntomas clínicos y generar políticas preventivas para minimizar las complicaciones inherentes a la patología.

The effect of the occupational mortality over the economy. Magdalena’s Fevers and tobacco farming in Colombia in XIX century

It is aimed at reviewing the effect reflected in the quality and quantity of tobacco exportation with the appearance of Magdalena Fevers in the Ambalema zone (Colombia), between 1856 and 1870. The research explores the effect of labor over health and the effect of health over labor in this stage of the Colombian export development. By formulating an econometric model it is possible to establish whether the epidemic outbreaks of fevers were a relevant factor in explaining the behavior of tobacco exports from Ambalema to the outside. The analysis of the empirical data shows that it is possible that a fall on the exports in about 72,000 tobacco sacks per year caused by the fevers in the studied region, as well as a negative effect of the disease on the tobacco prices.

Política africana de China: una manifestación de la real economy de corte chino

Desde el año 2000 el idilio China-África está marcado principalmente por un foro de cooperación, mecanismo de diálogo y cooperación colectiva ideado por China. Sin embargo, destaca que esta relación ha evolucionado en función de los intereses estratégicos de los chinos. China se inserta en los circuitos económico-comerciales africanos de manera metódica y decidida. A diferencia de sus competidores (Estados Unidos, Unión Europea, Canadá, Japón, etc.), que actúan en África de manera preferencial, China invierte en todos los países africanos sin ninguna excepción, sin importar su régimen político, su situación económico-financiera o su ubicación geográfica. Sin embargo, la voracidad energética china se ha vuelto objeto de preocupación en el Consejo de Seguridad de Naciones Unidas, sobre todo por su ofensiva por acaparar el mercado petrolero africano. Puede afirmarse que el actuar chino en África es una expresión de su pragmatismo económico-comercial, con efectos colaterales negativos para la integración y el desarrollo de África.-----Since 2000, the relationship between China and Africa is growing up because of the Forum on China-Africa Cooperation (FOCAC) which is a collective mechanism of dialogue and cooperation. Meanwhile, it’s important to mention that this relationship has increased regarding the Chinese strategic interests in Africa. China is getting inside the African economic and trade networks in a methodic and aggressive way. Differently from his competitors (USA, EU, Canada, Japan...) which only seem to use Africa, China invests in all the African countries without looking at their economical or financial situation, neither their geographical location. The energetical voracity of China has become a real issue at the United Nations Security Council, especially for the Chinese strike in the African petroleum market. For many reasons, we can affirm that the way China is acting in Africa is only the expression of its economical and trade pragmatism, which also has got negative results in the african development and integration process.

Efectos en las cualidades de la voz posteriores a la intervención con fonoterapia y lipoinyección en parálisis de pliegue vocal unilateral paramediana. Comparación de dos casos.

La temática del presente proyecto de investigación se centra en la descripción de los efectos en las cualidades de la voz, analizadas por el Multidimensional Voice Program (MDVP) de Kay - Elemetrics Corp. y el análisis de la estructura y dinámica de las cuerdas vocales a partir de la Videoestroboscopia Laríngea Computarizada (VELC), luego de la intervención en la Parálisis de Pliegue Vocal Unilateral en posición Paramediana (PPVUP), realizada a dos usuarios que consultaron la unidad de Laringe y Voz de la Clínica Avellaneda entre los años 2000 y 2003. En uno de los casos se utilizó la infiltración paracordal de grasa o lipoinyección y en el otro la fonoterapia o terapia vocal.

Poverty impacts of agricultural policy adjustments in an opening economy: the case of Colombia

We aim to contribute to the assessment of poverty impacts on the rural sector arising from agricultural policy adjustments in Colombia. For this we use an agriculture specialized static CGE model, jointly (sequentially) with a microsimulation model that allows for effective job relocation. Results indicate that the sectoral impact of the program implemented tends to be small and has considerable variability across crops. They also show that the highest impacts come from the irrigation and land improvements component of the program. Lastly, although it reduces poverty, poverty impacts are small and tend to concentrate in rural households toward the middle of the income distribution ladder.

Poverty impacts of increased openness and fiscal policies in a dollarized economy: a CGE-micro approach for Ecuador

We quantify the effects on poverty and income distribution in Ecuador of bilateral trade liberalization with the US and a budget-neutral value added tax increase which seeks to compensate tariff revenue losses. We stress the study of fiscal policies that the government could tap in order to compensate for tariff revenue loss. This is a very important issue for Ecuador because this country adopted the US dollar as its currency in 2000, forgiving the use of important policy instruments. To study these issues we combine a reduced-form micro household income and occupational choice model (using 2005/6 data from the Ecuadorian LSMS) with a standard single-country computable general equilibrium model (employing a 2004 SAM). We follow a sequential approach that simulates the full distributional impact of trade and tax policies. We find that the impact of these policy changes on extreme poverty and income distribution is small but positive.

Testing for Stock Market Integration in a Developing Economy: Colombia

This paper examines the linkage between two parallel stock exchanges trading the same shares in Colombia, namely the Bogotá Stock Exchange and the Medellín Stock Exchange. We provide empirical evidence to support the hypothesis that these two markets can be best described as fully integrated over a period of almost four decades, which is consistent with the view that arbitrage opportunities are only possible in the short but not in the long run. In addition, we find evide

The cyclical behavior of bank capital buffers in an emerging economy: size do matters

Using a panel of Colombian banks and quarterly data between 1996:1 and 2010:3, we study the relationship between short-run adjustemnts in bank capital buffers and the business cycle. We follow a partial adjustment framework and control for several variables that have been identified as important determinants of bank capital buffers in previous studies, and find that bank capital buffers vary over the business cycle. We are able to identify a negative co-movement of capital buffers and and the business cycle. However, we also find that capital buffers of small and large banks behave asymmetrically during the business cycle. While the former appear to be constant over time, once the appropriate set of control variables is used, the latter present a countercyclical behavior. Our results suggest the possible need of the implementation of regulatory policy measures in developing countries

The international economic crisis and the colombian economy

The purpose of this research is to provide an approximation to the likely effects of the crisis on the Colombian economy and to the effectiveness of policy response. For this, the most relevant transmission channels and policy measures are simulated in the setting of a static computable general equilibrium model (CGE). The results obtained are interesting in their own right and are in line with what could be expected given the information available on the behavior of the Colombian economy. Furthermore, they call into question the effectiveness of governmental intervention as judged by its intended countercyclical effects.

An artificial economy based on reinforcement learning and agent based modeling

In this paper, we employ techniques from artificial intelligence such as reinforcement learning and agent based modeling as building blocks of a computational model for an economy based on conventions. First we model the interaction among firms in the private sector. These firms behave in an information environment based on conventions, meaning that a firm is likely to behave as its neighbors if it observes that their actions lead to a good pay off. On the other hand, we propose the use of reinforcement learning as a computational model for the role of the government in the economy, as the agent that determines the fiscal policy, and whose objective is to maximize the growth of the economy. We present the implementation of a simulator of the proposed model based on SWARM, that employs the SARSA(λ) algorithm combined with a multilayer perceptron as the function approximation for the action value function.

A firm-level analysis of ICT adoption in an emerging economy: evidence from the colombian manufacturing industries

This study examines ICT adoption among 3,759 Colombian manufacturing firms, and attempts to identify the factors that are conducive to the adoption and usage of ICT at the firm level. Our major findings are (i) that the adoption of a given information and communication technology is better facilitated when a firm is relatively large, has large human capital, engages in more innovative activities, and when a firm’s organizational structure is better aligned with the given technology; (ii) that positive associations between the key determinants and ICT adoptions are more pronounced for small and medium-sized firms than for large ones, and (iii) that information spillovers within industries is also a determinant of ICT adoptions by the firms.

An Empirical Examination of the Determinants of Foreign Direct Investment: A Firm-Level Analysis for the Colombian Economy

We use a large firm level data set to investigate the determinants of foreign direct investment(FDI) in Colombia. We estimate econometric models for the determinants of the probabilitythat a firm receives FDI, as well as for the factors that help to explain the foreign share in afirm’s capital. The results show that firms listed on the stock market, involved in foreign tradeactivities, and operating in sectors with greater capital intensity are more likely to be recipientsof FDI. Also, the probability of a firm receiving FDI is directly related to its size.
