In higher education, student dropout is a relevant problem, not just in Latin America but also in developed countries. Although there is no consensus to measure the education quality, one of the ...important indicators of university success is the time to graduation (TTG), which is directly related to student dropout 1. Global estimates put this dropout rate at 42% 2. In the United States, this rate is around 30% and represents a loss of 9 billion dollars in the education of these students 3. However, desertion not only affects the quality of education and the economy of a country, but also has effects on the development of society, since society demands the contributions derived from the population with higher education such as: innovation, knowledge production and scientific discovery 4. Using basic statistical learning techniques, this paper presents a simple way to predict possible dropouts based on their demographic and academic characteristics.
Electricity distribution companies have been incorporating new technologies that allow them to obtain complete information in real time about their customers´ consumption. Thus, a new concept called ..."Smart Metering" has been adopted, giving way to new types of meters that interact in an interconnected system. This will allow to make data analysis, accurate forecasts and detecting consumption patterns that will be relevant for the decision-making process. This research focuses on discovering common patterns among customers from data collected by smart meters.

In recent years, many studies have emerged about regarding the topic of school failure, showing a growing interest in determining the multiple factors that may influence it 1. Most of the researches ...that attempt to solve this issue 2 are focused on determining the factors that most affect the performance of students (dropout and failure) at the different educational levels (basic, middle and higher education) through the use of the large amount of information that current computer equipment allows to store in databases. All these data constitute a real gold mine of valuable information about students. But, identifying and finding useful and hidden information in large databases is a difficult task 3. A very promising solution to achieve this goal is the use of knowledge mining techniques or data mining in education, which has resulted in so-called Educational Data Mining (EDM) 4. This new area of research is concerned with the development of methods for exploring data in education, as well as the use of these methods to better understand students and the contexts where they learn 5.
In the new global and local scenario, the advent of intelligent distribution networks or Smart Grids allows real-time collection of data on the operating status of the electricity grid. Based on this ...availability of data, it is feasible and convenient to predict consumption in the short term, from a few hours to a week. The hypothesis of the study is that the method used to present time variables to a prediction system of electricity consumption affects the results.

This article presents a bibliometric review on the researching topic "Contribution to the competitiveness of energy financing in the Colombian business sector", limited from 2011 to 2021. The review ...was carried out using the Scopus database, obtaining a set of 76 studies in Colombia within the 2609 documents analyzed. After having applied the different filters and search strategies, these studies were analyzed using the Bibliometrix package of the statistical software R. The results identified, for example, that the world production of publications shows an upward trend, with the largest number of scientific investigations presented in 2020. It was also found that one of the most relevant sources is the International Journal of Energy Economics and politics, with five published documents. On the other hand, the most cited local source is Energy Policy magazine, with 90 citations and that the most cited local authors are Cadavid L.
El objetivo de esta investigación es analizar el marco legal que se ha diseñado en Colombia para el emprendimiento, y observar cómo este impacta en la generación de empleo. La metodología utilizada ...fue de corte cualitativo con apoyo de la revisión documental, consultando y examinando diversos documentos y datos de corte científico como publicaciones, leyes, estudios de casos y artículos de revistas de corte académico. Para cumplir con los objetivos trazados se realizó una matriz de análisis bibliográfico que permitió filtrar los documentos seleccionados y extraer la información utilizada para este documento. Los resultados permiten visualizar los aspectos que son susceptibles de mejora y que pueden beneficiar el crecimiento del emprendimiento, renglón de vital importancia en el país, toda vez que genera el mayor número de empleos en la actualidad. La conclusión final sugiere oportunidades para el fortalecimiento del marco legal colombiano en lo relacionado con el emprendimiento, para así propiciar mayores oportunidades tanto en el ámbito social como económico.
