Perception of trust and commitment in the financial sector in Bogota (Colombia)

This study aims to determine the variables through which financial sector entities can establish retention processes and create long-term and quality relationships with Bogota's financial consumers. This was done by applying a survey to a sample of 384 people. The perception of trust and commitment of financialconsumers is between regular and non-conforming however, it was possible to establish significant variations between such perception associated with age groups, number of years linked to the financial institution, marital status, type of economic activity and the number of financial products

Prediction rules in e-learning systems using genetic programming

This paper describes the use of Data Mining Techniques to improve teaching–learning processes in the linear programming course offered at the Engineering Faculty at Mumbai University, India. The proposed approach seeks to model the student’s interaction with the study material using prediction rules whose interpretation will allow to detect the weaknesses of the educational process and evaluate the quality of the study material. The proposed rule discovery method is the Evolutionary Algorithms and particularly the Grammar-Based Genetic Programming (GB-GP), which is compared to association rules and decision tree construction for discovering prediction rules

Association rule mining for customer segmentation in the SMEs sector using the apriori algorithm

Customer´s segmentation is used as a marketing differentiation tool which allows organizations to understand their customers and build differentiated strategies. This research focuses on a database from the SMEs sector in Colombia, the CRISP-DM methodology was applied for the Data Mining process. The analysis was made based on the PFM model (Presence, Frequency, Monetary Value), and the following grouping algorithms were applied on this model: k -means, k-medoids, and Self-Organizing Maps (SOM). For validating the result of the grouping algorithms and selecting the one that provides the best quality groups, the cascade evaluation technique has been used applying a classification algorithm. Finally, the Apriori algorithm was used to find associations between products for each group of customers, so determining association according to loyalty

Socialization Competitiveness factors that impact business efficiency: a study in Latin America and Europe

La información empleada fue obtenida del Reporte Global de Competitividad (en inglés, Global Competitiveness Report) entre los años 2007 y 2020 para los países pertenecientes a América y Europa. En este reporte se expone el Índice Global de Competitividad (GCI, por sus siglas en inglés). Este índice fue establecido en 1979 por el Foro Económico Mundial para determinar la competitividad de los países, sobre la base de criterios seleccionados y se actualiza periódicamente. El último reporte se calculó para 152 países en 2020. Los datos utilizados en el cálculo se obtienen de fuentes como los ministerios cada país, instituciones estadísticas, colaboradores del Foro Económico Mundial, Economist Intelligence Unit y el Fondo Monetario Internacional, entre otras. Así mismo, se obtiene información por medio de la encuesta del Foro Económico Mundial.The information used was obtained from the Global Competitiveness Report between 2007 and 2020 for countries in the Americas and Europe.

Overcrowding in prisons of Colombia (1991-2016)

The purpose of this document is to answer: what is the panorama of prison overcrowding in Colombia between 1991 and 2016? This document facilitates the understanding of the prison crisis that crosses the country and emphasizes in a phenomenon rarely seen. It was evidenced that since 1991 there is an increasing attendance of the PPL in the case of women with a growth of 444% compared to 2016 and in the men of 305%. There is overpopulation with a continuous upward trend since 1991, housing in recent years more than double the population that could be given the installed capacity

Comprehensive system of management of the quality, environment and occupational risks in the health sector

Integrated management systems (SIG) arise as an improvement alternative that allows health sector companies to achieve their objectives in line with the expectations and needs in terms of quality, safety and health at work (TSS) and medium environment, its internal and external stakeholders. The present study tries to reveal how these companies have carried out the process of incorporating SIG, what their conception about the benefits of the same and also, reveals if at present these companies carry out integrated audits to guarantee the effectiveness of the system. Among the findings is that if the SIG is not incorporated in the appropriate way can generate contradictory effects in health companies as there may be incompatibilities between the requirements of quality, TSS and environmental management
