Marco de Buenas Prácticas para la Iniciación y Planeación en Gestión de Proyectos de viviendas de interés social en Corvivienda, Cartagena de Indias D.T y C

This research contributes to the solution of the evaluation of the management of projects in the Housing Fund for Social Interest and District Urban Reform (Corvivienda), of the city of Cartagena de Indias D.T. and C., determining the level of use and application of techniques and tools in the processes of initiation and planning of projects, identifying their strengths and weaknesses that serve as a starting point for the subsequent improvement of the construction of social housing in managing your projects. It is stated that one of the possible reasons for the non-compliance with the goals in the construction of affordable housing in the programs of the municipal administration of Cartagena de Indias, and a high rate of failed projects in Corvivienda, is due to the low level of application of good practices in project management. Finally, a didactic guide is prepared of the main recommendations to improve the initiation and planning processes of their projects, based on the deficiencies of the project management processes detected in the findings and based on the literary revie

A comprehensive risk management review for financial instruments using different value at risk approaches: which methodology improves market risk valuation?

Trabajo Fin de Grado en Economía y Finanzas . Curso Académico 2019-2020In recent years, there has been an incrementing need within the financial industry to make use of more sophisticated models to quantify the associated risk in any investment or financial activity, with the goal of achieving an adequate risk management and control in decision-making processes. Accordingly, throughout this academic research project, we present a review of the different methodologies surrounding the Value at Risk framework, one of the most common tools in financial risk analysis and quantification. We perform a deep analysis from standard approaches for measuring VaR to the more complex techniques. We will also review some backtesting procedures used to evaluate VaR models. Therefore, the main focus of this research will be to implement a theoretical and practical analysis of several value at risk methodologies and discuss their respective behaviour under real life scenarios including low but also high volatility periods, such as the one fostered by the recent Covid-19 pandemic. To carry out the investigation, historic data from the daily log returns of the Dow Jones Index will exploited through the open-source software R. Results in this paper suggest that the GARCH (1,1) model parametric approach to VaR is the best method for forecasting VaR, especially under the Student-T distribution assumption of returns. The Historical Simulation non-parametric approach, as well as the Moving Average Volatility model, also had promising results under relatively stable circumstances, but showed their weaknesses when the situation changed and volatility in financial markets dramatically increased as a consequence of the current health crisis. For its part, empirical literature highlights the lack of accuracy of the traditional Riskmetrics methodology, fact that was also observed here, where we obtained very discouraging results under such approach. Lastly, it seems that the Extreme Value Theory significantly underestimated risk, resulting in a surprisingly bad performanc

Diseño de un modelo de gobierno para una fase especifica de los proyectos en el sector de refinación y petroquímica en Cartagena-Colombia

This document proposes a governance model for one of the most critical phases of the life cycle of the refining and petrochemical sector projects, taking as a reference the best practices from the technical point of view raised by industrial referents worldwide, such as UOP and the PDO and NORSOK, this latest reference of standards and standards in the oil and gas industry worldwide. The most relevant topics will be discussed and recommendations will be made by approaching the local industry. © 2022 Latin American and Caribbean Consortium of Engineering Institutions.

La política monetaria única y sus efectos regionales.

El interés por el estudio de los efectos asimétricos que puede tener la política monetaria única (PMU) en los países integrantes de la eurozona ha dado origen a una ingente literatura, fundamentalmente de carácter empírico, que se ha ocupado de analizar las respuestas del output y los precios de los países europeos ante los supuestos shocks monetarios ocasionados por las decisiones de política monetaria adoptadas por el Banco Central Europeo (BCE). Buena parte de ella revela la existencia de importantes diferencias no sólo en el impacto total que los shocks monetarios ocasionaban en el output y los precios de distintos países, sino también en sus trayectorias temporales, lo cual era interpretado como un indicio de las asimetrías regionales que ocasionaría la puesta en marcha de la PMU en la eurozona. En este trabajo se realiza una síntesis del debate en torno a las asimetrías regionales de la PMU teniendo en cuenta la experiencia y la documentación empírica que se ha ido generando en estos casi quince años de trayectoria de la eurozona, con la doble intención de: propiciar una reflexión crítica al respecto de los resultados empíricos obtenidos hasta la fecha y apuntar algunos cambios que habría que introducir en el actual marco operativo de la PMU.Increasing interest in exploring the possible asymmetric effects of Single Monetary Policy (SMP) on euro zone countries has resulted in a great deal of research, most of it empirical in nature, into the response of GDP and prices in European countries in the face of the monetary shocks caused by the monetary policy measures adopted by the ECB. Much of this research points to the existence of major differences not just in the overall impact of monetary shocks on growth and prices in different countries but also in their timing. This has been interpreted as a sign of regional asymmetries that could be caused by implementing the SMP in the euro zone. Taking into account the experience and empirical evidence built up over the almost-fifteen-year history of the euro zone, proposals are made for changes that should be introduced in the current operational framework of the SMP with a view to palliating those asymmetries

Aporte al conocimiento de la biología de Cissites maculata (Coleoptera: Meloidae) en Venezuela

Se aportan material fotográfico y descripciones de Cissites maculata (Swederus, 1787) basadas en observaciones de adultos, huevos y larvas en primer estadio, encontrados en una viga de madera cerca de la entrada de un nido de Xylocopa sp., en Venezuela. Se caracterizó la masa de huevos y las eclosiones en el tiempo y se realizaron algunas mediciones en los huevos, larvas y adultos utilizando una técnica digital con herramientas de diseño gráfico. La masa de huevos consistía en ≈ 23400 huevos y una hembra no contribuyó con la postura. El tamaño de los huevos fue mayor que los documentados para Cissites auriculata (Champion, 1892). Este trabajo complementa lo descrito para la especie y amplía la escasa información sobre su presencia en Venezuela, incluyendo aspectos que no han sido documentados en el país
