An analysis of the learning objectives of "written communication" using rubrics: a preliminary review of the macroeconomic theory i course
(Linda G. Snetselaar - PhD, RDN, LD, FAND, 2014-01-01) Alonso Cifuentes, Julio César; Alonso Cifuentes, Julio Cesar
This paper discusses one of the peculiarities of information collected by rubrics, i.e. the qualitative nature of the categorical variables gathered. The qualitative nature of this data does not allow using conventional univariate statistical techniques such as, for example, calculating means and variances, or multivariate statistical techniques such as correlation or regression analysis. To address this issue, we turned to latent variable models and item response theory (e.g. a Rasch-family model). We apply this methodology to asses the "Written Communication " learning goal in a Macroeconomic Theory course.
Assessing the Forecasting Performance of Structural Models for the Nominal Exchange Rate : The Colombian Case *
(Researchgate, 2005-06-27) Alonso Cifuentes, Julio Cesar
This paper analyses the out-of-sample forecasting performance of three models for the USD/COP nominal exchange rate during the period 1984:I – 2004:I. The sticky price monetary (Dornbusch (1976) – Frankel (1979)) and the Balassa–Samuelson (which gives a central role to the productivity differentials) approaches are used. Additionally, the Purchasing Power Par ity condition (PPP) is analyzed. The forecasting ability of these models is comp ared using a random walk as a benchmark model. The metrics employed in evalua ting the forecasting performance are RMS, MAE, MAPE and U-Theil. It is found that despite the great ability to predict, no model outperforms the random walk. This conclusion strengthens the previous results in the nominal exchange rate modeling literature.

Ante la transición de Santiago de Cali a Distrito Especial, Deportivo, Cultural, Turístico, Empresarial y de Servicios en agosto de 2018 a través de la Ley 1933, surgen oportunidades y retos para la ciudad y su administración en términos del fortalecimiento institucional en el territorio, el desarrollo de nuevas funciones para niveles locales de gobierno, el enfoque mismo de las problemáticas que entrarían a ser parte del campo de acción del Alcalde Mayor y la relación del Distrito frente al Gobierno Nacional en torno a las temáticas que impulsarán la transformación a su nueva condición [Propacífico]. Las grandes metrópolis latinoamericanas en su proceso de crecimiento han adoptado diferentes estructuras administrativas buscando responder tanto a su relacionamiento con otros entes territoriales adyacentes como a su estrategia interna y a su modelo de relacionamiento con el ciudadano. Santiago de Cali, capital del Valle del Cauca y núcleo de desarrollo del Suroccidente colombiano ha experimentado un rápido proceso de crecimiento que ha redundado en una ciudad (y una región metropolitana) de cerca de dos millones de habitantes, compleja, extensa y con una conformación sociodemográfica diversa y multicultural [Enrique Rodríguez Caporalli y Pablo Sanabria Pulido].
Clustering dynamics within the cultural industries: the case of Cali - Colombia.
(Universidad Icesi., 2017-01-01) Alonso Cifuentes, Julio Cesar; Rios, Ana María
The primary objective of this paper is to provide relevant information, from a microeconomic perspective, for the decision-making process followed by entrepreneurs interested in being part of the cultural industries (IC) in the city of Cali, Colombia. To that end, we will make use of a data clustering technique and the Herfindahl Index, to measure the dynamics of agglomeration within the IC, according to their absolute and average sales volume, the concentration of market power and the number of employees hired in average by each cultural subsector. We found that there is a strong asymmetry in the distribution of market share within the majority of cultural activities and a clear division of clusters of cultural subsectors whose behavior is similar for each variable analyzed.
Una mirada descriptiva a las comunas de Cali
(Universidad Icesi, 2007-12-01) Universidad Icesi, Centro de Investigaciones en Economía y Finanzas
En la actualidad el municipio de Santiago de Cali cuenta con un sistema de información que ha permitido al Departamento Administrativo de Planeación Municipal (DAPM) recopilar un conjunto de información por comunas que constituye el primer paso para la construcción de un sistema local que permita la planeación y seguimiento de políticas públicas. El DAPM, con la publicación Cali en Cifras, ha venido recogiendo información de las comunas desde el 2001, lo cual ha permitido por primera vez en la ciudad tener una fuente de información confiable y continua de la vida en las comunas. En el último año, la disponibilidad de nuevas bases de datos permite complementar esta información que tradicionalmente recopila el DAPM. Estas bases de datos son: el Censo de población del 2005, el Censo económico del 2005, y la información de las encuestas de clasificación del SISBEN. Esta nueva información y la anteriormente disponible nos permite presentar en este volumen un primer intento por caracterizar demográfica, económica y socialmente las 22 comunas del municipio de Cali. Este análisis permitirá entender de manera rápida las características de cada una de las comunas de Cali y esperamos que esto facilite el proceso de planificación local.
TEST: Serious games for radio communications learning
(Ieee, 2013-12-19) Pradilla, Juan Vicente
The game industry has suffered an impressive explosion of popularity, becoming the largest entertainment industry in the world. Games have become a sophisticated extension of the reality and an interesting way for complementing human mind utopias. Training software allows the trainee to immerse in quasi-real controlled situations that could be measured by trainers. In this work we discuss the duality existing between the training based on a serious game and a simple game, based on state of the art technologies. Then we show a training system for telecommunications technicians based on a combination between serious games and "traditional" e-learning platform. We show results for a trial made with a group of students from different disciplines (not only engineering) in order to evaluate learning outcomes using serious games versus other learning approaches. In this paper we discuss such results and make a descriptive statistical analysis of the results
Una propuesta para la construcción de rankings de programas de pregrado en Colombia: los casos de ingeniería industrial y de sistemas
(Asociacion Colombiana de Facultades de Ingeniería ACOFI, 2015-12-01) Ulloa Villegas, Gonzalo Vicente
This document presents a proposal for using Standardized-exit exams to rank undergraduate programs. The proposed takes into account each program's mean score, volatility, students' proportion with scores above the national mean, and the number of students taking the exam. The document presents an application of the suggested index for two different programs in Colombia: Software Engineering and Industrial Engineering. The results show that five out of the top ten Industrial Engineering and Industrial Engineering programs are located in Bogota (the capital). On the other hand, 40% of the top ten Industrial Engineering and Software Engineering programs are offered by public schools. Finally, 60% of the top twenty Software Engineering programs hold a high quality accreditation. For Industrial Engineering programs 70% of the top twenty programs have the high quality accreditation. Future studies will determine the robustness of the proposed indicator to changes in its weights and its application to other professional programs and topics in standardized tests. However, this proposal represents an effort to process the results of standardized exams to provide information that can be used to compare educational programs and hence, for the assessment and formulation of educational policy.
