Abstract: Pairs trading is a well-known and widely used strategy in the financial industry. Many academic papers have been published regarding to this topic, mainly applied over samples in the stock markets. This project attempted to analyze the application of a simple pairs trading rule in the Foreign Exchange Market, until now poorly approached. Therefore, our aim with this work was to address, through an empirical analysis, a market-neutral strategy that takes into account pairs of exchange rates that “move together” and exploits their plausible inefficiencies. Based on a co-integration model, we designed and tested the strategy, which surprisingly yielded valuable evidence of its potential scope. The sample employed for the development of this project included 9 of the most liquid currencies in the market, from 2010 until 2014, so it was possible to open and close positions at the right moment without delays. Resumen: El trading de pares es una estrategia bien conocida y ampliamente usada en la industria financiera. Muchos documentos académicos han sido publicados en relación a este tema, principalmente aplicado sobre muestras en el Mercado Accionario. Este proyecto buscó analizar la aplicación de una estrategia de trading de pares simple en el mercado de divisas, hasta ahora escasamente abordado. Por lo tanto, nuestra intención con este trabajo consistió en estudiar, a través de un análisis empírico, una estrategia de mercado neutral que toma pares de divisas que "se mueven juntas" y explota sus in-eficiencias plausibles. Basado en un modelo de cointegracion, se diseñó y probó la estrategia, que de manera sorprendente retornó evidencia valiosa de su alcance potencial. La muestra empleada para el desarrollo del proyecto incluyó nueve de las divisas más liquidas en el mercado, desde 2010 a 2014, para que fuese posible abrir y cerrar posiciones en el momento justo sin retrasos.

El conflicto cubano en el teatro español (1868-1902): ¡Libertat!, un estudio de caso = The cuban war in the spanish theater (1868-1902): ¡Libertat!, a case study

Por: Laura Daniela Buitrago Santana | Fecha: 2015

Durante el siglo XIX, el teatro fue uno de los productos culturales más importantes de España. La repentina aparición de espacios interpretativos así como la masiva producción de obras a partir de 1860 confirma el auge de una actividad teatral surgida en medio de una transformación sociopolítica definitiva para el país. Entre los géneros más representados se encuentra el teatro político-patriótico, que sirvió como elemento propagandístico de la ideología hegemónica para justificar guerras como las que por aquel entonces se libraban en África (1850-1860), Filipinas (1896-1898) y Cuba (1868-1898). En particular, los acontecimientos de ésta última fueron continuamente representados en los escenarios y abrieron candentes debates en torno a la libertad, la autonomía, la esclavitud y la independencia. Varios autores han estudiado el teatro que surgió durante el conflicto cubano, haciendo énfasis en el carácter nacionalista disfrazado en diversas alegorías o incluso directamente enunciado. No obstante, existe un misterioso silencio en torno a las consecuencias de lo que se conoce popularmente como el Desastre del 98, específicamente sobre lo que se refiere a la independencia de Cuba y la pérdida de las últimas posesiones ultramarinas. Ello supone un vacío investigativo del que si bien se habían percatado algunos investigadores, no parece haberse indagado en profundidad. Ante esta situación, el presente trabajo propone una perspectiva por medio de la cual se intenta exponer cómo el silencio resulta ser una poderosa herramienta de expresión, al analizar la traducción de la obra de Santiago Rusiñol, ¡Libertat!, realizada por Jacinto Benavente.

The modern intelligent investor: Can value and growth investing strategies evolve to maximize returns and reduce risk? = Colombia: pueden las estrategias de inversión por valor y por crecimiento evolucionar para aumentar los retornos y reducir el riesgo

Por: Elías Alberto Marun Helo | Fecha: 2013

This research explores the origin and evolution of value and growth investing strategies focusing on the principles that reduce risk and maximize the potential for future returns. These are contrasted with the theory and practice of efficient markets hypothesis which allows passive investors to achieve a respectable average return but discourages active portfolio management. Acknowledging the difficulty of outperforming the market by private investors, this research refers to the two drivers of successful stock picking: (i) the attitude of the investing community towards the market and/or the targeted stock at the time of purchase and, (ii) the value and growth potential of the underlying business. Concerning the first driver, asset overpricing and financial bubbles are analysed from the perspective of behavioural finance as a tool for timing the investing decision. Regarding the second driver, a framework for the quantitative and qualitative analysis of the underlying business is developed in order to provide the enterprising investor with the tools to reduce risk and maximize returns. To support these findings, a number of business cases are presented showing that consistent valuation of long Competitive Advantage Period (CAP ) companies, complemented with adequate market timing has the potential to outperform the market in the long run.

Trade Liberalization and Food Security: The Case of Bolivia after the Structural Reforms of 1985 = Liberalización comercial y seguridad alimentaria: el caso de Bolivia luego de las reformas estructurales de 1985

Por: Mauricio Giovanni Valencia Amaya | Fecha: 2009

This research shows the relationship between trade liberalization and food security for the Bolivian case. As a result of the severe economic crisis of the early-1980s, Bolivia adopted a series of market-oriented reforms in 1985. The reforms included the liberalization of the trade regime and the promotion of non-traditional exports. The trade liberalization had an important effect on the performance of cash crops, especially in the development of the soybeans industry. However, food crops did not have such a great dynamics. Vegetables and starchy roots declined in per capita terms and the increase in imports were not enough to compensate the decline. Trade reforms mostly favor a small group of large-scale farmers in the lowlands, who had historically been granted land in the region. In this sense, Bolivia’s involvement in a trade liberalization process has not been reflected in an overall improvement of the country’s food security.

Une théorie physicaliste de la conscience phénoménale

Por: Reinaldo José Bernal Velásquez | Fecha: 2011

Cette thèse propose une théorie métaphysique de la conscience phénoménale, que j'appelle « ephysicalisme ». Elle part d'une attitude réaliste face à l'expérience subjective: il y a des entités telles qu'il y a quelque chose comme l'effet que ça fait, intrinsèquement, d'être l'une d'elles (Nagel 1974). En premier lieu, je défends une métaphysique physicaliste. Deuxièmement, je rejette l'idée selon laquelle la conscience est une propriété survenante et en particulier l'intelligence artificielle forte et le fonctionnalisme computationnel. Troisièmement, je critique les théories de la conscience « d'ordre supérieur » (HOT), et j'analyse « l'unité de la conscience » ainsi que ce qu'on appelle le « fossé explicatif » (Levine 1983). Quatrièmement, je défends la thèse selon laquelle la conscience est une propriété émergente des entités conscientes: elle est, par rapport aux micro-constituants de la base d'émergence, une propriété ontologiquement nouvelle qui possède des pouvoirs causaux originaux. Cinquièmement, je critique « l'argument du zombies"" de Chalmers (1996) et “l'argument de la survenance” de Kim (2005). Finalement, je défends la thèse selon laquelle les contenus phénoménaux sont des propriétés physiques, et je discute «l'argument de la connaissance» de Jackson (1982).

Social housing as a strategy for strengthening inclusion in a post-conflict scenario: The case of Colombia’s 100 thousand free houses

Por: Nathalia Mosquera Palomeque | Fecha: 2015

Colombian cities have been for over 60 years witnesses of the internal conflict that through time morphed into a heterogeneous war, causing the forced displacement of approximately 6.3 million people during the period between 1985 and 2015. The lack of instruments able to benefit this population, triggered the issuance of two statements of the Constitutional court forcing the national government to take action towards their repair and integration. With the aim of building sustainable and inclusive cities through social housing and at the same time reducing quantitative housing deficits, the national government set the goal of building 100.000 free housing solutions. Over 90.000 housing units were built across the national territory, keeping the promise made, but raising questions about the quality of social housing and the impacts these projects are having on Colombian cities built environment. This dissertation will analyse the degree to which this programme can provide an effective basis for creating inclusive housing processes in post-conflict Colombian cities. The first chapter will try to understand the meaning of the word inclusion, and will conclude with an applicable analytical framework that will set the basis and a set of lenses to understand and analyse how the projects are conceived, built and delivered. The second part will explain the characteristics of the Colombian conflict, its effects on the urbanization patterns of cities and the way in which housing policy has developed in parallel to it. Additionally, the third chapter will try to confront the analytical framework with the 100.000 free houses program. The expected outcome of this analysis is to open a discussion on the role of social housing and the challenges it faces in the task of transforming Colombian cities into inclusive centres in which to acquire a tangible peace.

Suction and volume changes of Compacted sand-bentonite mixtures = Cambios volumétricos y de succión en muestras compactadas de arena-bentonita

Por: Julio Esteban Colmenares Montañez | Fecha: 2002

Engineered barriers are used in the containment of hazardous materials and are usually a composite of compacted clayey soil and a synthetic membrane. Containment elements such as landfill liners should be designed to control or prevent leachate migration or groundwater ingress. Engineering specifications for a compacted clay liner are based mainly in a hydraulic conductivity less than 10-9 m/s and the need for stability during construction and operation of the landfill. Sandbentonite mixtures are often used as a barrier material. The addition of relatively small amounts of bentonite (5-15%) can improve the performance of a granular material providing both a low permeability and an enhanced mechanical stability. However not all the possible compaction conditions produce a low permeability and mechanically stable material. Changes in water content after compaction can cause swelling or collapse depending on the stress and suction conditions before the water content change occurs. A laboratory investigation of the swelling-collapse behaviour of compacted mixtures of Sand-bentonite has been undertaken. Compaction and suction characteristics were established. The suction and volume change characteristics were investigated through a series of oedometer tests. The central part of the experimental programme focused on the detailed investigation of the processes of swelling and collapse during controlled wetting.To do this, a significant number of modifications were required to the existing apparatus. Fabric studies including Environmental Scanning Electron Microscopy and Mercury Intrusion Porosimetry were also undertaken. Intrinsic behaviour and the relationship between suction and water content were comprehensively studied. A parametric study of the influence of bentonite content and sand grading was also undertaken. The results are presented and analysed. Recommendations for future research are made.

Evaluating the economic feasibility of biochar production as a means of carbon capture and storage = Evaluación de factibilidad de la producción de biochar como método de captura y almacenamiento de dióxido de carbono

Por: David Echeverry Gómez | Fecha: 2014

Carbon Capture and Storage (CCS) is an emerging technology designed to tackle climate change by making processes more sustainable. This work gives a technical review of the current status of this process in order to compare it with the production of biochar. The latter is a carbon-rich material obtained when biomass is heated in the absence of oxygen. Although this production technique, which is called pyrolysis, has been known for centuries, there is little information regarding its process at an industrial level. As a result, this dissertation presents a study of the feasibility of biochar production as a means of carbon capture and storage. In other words, this research generates an approach to provide a preliminary estimate of the potential of large-scale biochar production to reduce atmospheric CO2. In this context, it is important to consider that pyrolysis-based biochar could be valuable in terms of soil improvement, crop yield increase, bioenergy generation and greenhouse gas (GHG) offsets. In this perspective, there are two categories of pyrolysis: fast and slow. Fast pyrolysis produces biochar in a matter of seconds, whereas slow pyrolysis produces a higher conversion to biochar but in a matter of hours. Generally speaking, the pyrolysis-based process is considered to be carbon-negative, because biochar production could reduce the amount of carbon in the atmosphere. In terms of the data analysis, several factors were considered and some assumptions were made. These assumptions are based on the literature because biochar production is not yet available at a commercial scale. According to the results, the cost to capture a tonne of carbon dioxide is $6.47 and $32.49 for fast and slow pyrolysis respectively. Therefore, although it is not a profitable technology, it could be cost competitive compared with CCS projects.

Life cycle assessment and carbon footprint for the production of biochar as an alternative of soil remediation = Análisis del ciclo de vida y huella de carbono para la producción de biocarbón como alternativa de remediación de suelos

Por: Alfonso Rolando Rodríguez Pinilla | Fecha: 2013

The use of biochar such as a “gentle” in situ soil remediation technique has received attention in recent years. The production and characteristic of biochar are influenced mainly by the operating conditions of conversion process and feedstock composition. Although the commercialization of biochar as a soil amendment is still in its infancy, some companies in the UK have ventured into the production and development of biochar products with very good results in the management of contaminants in soils. The environmental benefits and impacts of biochar produced by fast pyrolysis were modelled and compared with carbon footprint and life cycle assessment (LCA) methodologies. Four different kinds of feedstocks were selected. These were two kinds of straw (barley and wheat) and two kinds of wood chips (pine and beech). Pine wood reported the highest net emission with 4.9 1 t CO2 eqt-1 biochar while wheat straw was the lowest with 1.6 t CO2 eqt-1 biochar. This difference was correlated with the composition of lining in the feedstock. At the same time, the major contribution of GHG emission to the system boundary is for the pyrolysis process with the 99% for all feedstocks others aspects also were evaluated. Nine of fourteen impact categories selected were analysed for the LCA methodology. However, absolute values of this assessment remain difficult to interpret, and for that reason a normalisation with European and global loads step was applied. The biggest demonstrable impact from wheat straw charring is on ecotoxicity for aquatic fresh water. It was found that many factors, specially the selection of the type of feedstock in the production of biochar by fast pyrolysis, affect not only the characteristic of the product but also its environmental impacts in a significant level.

Evaluation of the programme early childhood develop in Colombia. Looking to improve the human capital = Evaluación del programa primera infancia en Colombia. Buscando un mejora en el capital humano

Por: Carolina Ramírez Borrero | Fecha: 2012

This paper studied the impact of a programme of Early Childhood Development that is giving nutritional supplements and home stimulation to children in four regions of Colombia during 2011. The aim of this study was to evaluate the improvement on anthropometric measures, haemoglobin and anaemia as a way to increase the human capital. It was found that the baseline data has similar characteristics of programmes such as Demography and Health Survey and Familias en Acción. It was found a high incidence of age and gender on growth and reducing stunting. Likewise, it was found significant increase in haemoglobin and reducing anaemia, which is mainly a result of age, concentration of haemoglobin itself and evaluated region. The study was not able to find significant effects of the intervention compared to the control group, possibly because the incidence of other explanatory variables.
