Modeling and comovements of the Colombian exchange rate, 2011-2017 [Modelación y co-movimientos de la tasa de cambio Colombiana, 2011-2017]
The exchange rate is influenced by multiple national and international macroeconomic factors, which generates high levels of uncertainty. The objective of this research is the construction of ARIMA-GARCH and ARIMAX-GARCH ... -
Logistics education for business management students: A learning-doing and service-learning approach
This article develops a teaching methodology in logistics for students of business administration programs to solve real problems in companies and integrate the knowledge acquired in logistics management courses. The ... -
Memberships Networks for High-Dimensional Fuzzy Clustering Visualization
Visualizing the cluster structure of high-dimensional data is a non-trivial task that must be able to deal with the large dimensionality of the input data. Unlike hard clustering structures, visualization of fuzzy clusterings ... -
Learning based on educational games: Case University in Colombia [Aprendizaje basado en juegos formativos: Caso Universidad en Colombia]
New generations require a more dynamic learning process, that's why high education institutions have begun to articulate new pedagogical tools in the different areas of knowledge. The objective of this article is to design ... -
Lovemark effect: Analysis of the differences between students and graduates in a love brand study at a public university [L'effet « lovemark »: Une analyse des différences entre les étudiants et les diplômés dans une étude d'une « marque d'amour » dans une université publique] [Efeito lovemark: Análise das diferenças entre estudantes e graduados em um estudo de amor pelas marcas realizado em uma universidade pública] [Efecto lovemark: Análisis de las diferencias entre estudiantes y egresados en un estudio de marca de amor en una universidad pública]
The purpose of this paper is to consolidate the measurement of a lovemark and unify a set of elements that form a lovemark in university institutions by considering the differences between students and graduates. Based on ... -
Experimental and computational data set on adsorption of Cr (VI) from water using an activated carbon
Chromium (Cr) is a widely used metal in metallurgical and chemical industries, whose waste contaminates the surface and groundwater. Cr (VI) is toxic and produces carcinogenic effects owing to its high mobility in water ... -
