Descripción: la reflexión nace de la investigación que realiza la autora en su tesis doctoral y de los trabajos en formación universitaria, extensión e investigación en economía social y solidaria.</p> <p>Está dirigida a los investigadores, en general, y a los educadores de la economía social solidaria, en particular. Punto de vista: la incorporación a la vida cotidiana comunitaria de las experiencias en todos los niveles y carreras de grado, pregrado y posgrado, relacionados con la economía social solidaria, es una condición indispensable para el desarrollo endógeno, dado que no se puede transformar aquello que no se conoce.</p> <p>Conclusiones: los saberes del territorio en la economía solidaria requieren nuevos aprendizajes en espacios-foros, los cuales permiten la construcción social y colectiva de nuevas epistemologías del conocimiento que, en vez de reproducir la hegemonía y actitud monocultural, propician un crecimiento conjunto de procesos de coconstrucción de conocimientos de beneficio mutuo.</p> Mónica Lizeth Sánchez-Arévalo Luisa Fernanda Cruz-Hueso Roberto Ferro-Escobar ##submission.copyrightStatement## 2018-12-12 2018-12-12 14 26 10.16925/in.v14i26.2433 Maturity Level Model for Entrepreneurship Processes in Colombian smes <p style="margin-bottom: 0.14in; line-height: 115%;">Introduction: This research, conducted in 2017 at the Universidad Distrital Francisco José de Caldas, presents a proposed maturity model applied to entrepreneurial processes in Colombian smes. Its aim is to diagnose the entrepreneurial action in these organizations by assessing five factors: entrepreneur profile, economic and financial aspects, market conditions, knowledge creation and dissemination, and ict solutions, and relate them to various maturity levels proposed by the cmmi (Capability Maturity Model Integration) method. Methods: a) Literature referring to entrepreneurship and maturity models is reviewed; b) the main factors for entrepreneurship processes are identified; c) the maturity model is designed; d) the model is validated by means of the Delphi method and expert judgment; e) the statistical analysis of tests results is carried out; and f) conclusions and improvement actions are proposed to increase the maturity level of the “market conditions” factor, which is elaborated throughout the document. Results: The validated maturity model shows an experts’ acceptance percentage of 83.75%, suggesting some improvements to the proposed levels. Conclusion: This model shows the situation of entrepreneurship processes for already incorporated companies and, through its implementation by an expert, intends to create improvement actions and make entrepreneurship a tool for the organization’s economic growth. Limitations: The proposed model has not been tested in an sme and is currently in its conceptual construction. Originality: A similar model has not been established to assess entrepreneurial processes in companies using the cmmi method.</p> Laura Camila Ñungo Pinzón Brayan Torres González José Ignacio Palacios Osma ##submission.copyrightStatement## 2018-12-12 2018-12-12 14 26 1 17 Early Warning System for Rain-Induced Mass Movement for Ciudad Bolívar (Colombia) <p>Introduction: This research article introduces an early warning system for rain-induced mass movement for the district of Ciudad Bolívar, in Bogotá, Colombia, developed at the Universidad Distrital Francisco José de Caldas in 2018. Methods: A sensor network was developed by means of a base station, which is responsible for issuing a warning if there is a risk of landslide. Results: The data provided by the sensor network, such as humidity and temperature, issue warnings to increase the possibility of saving the lives of vulnerable population in the district. Conclusion: This project seeks to save the most important thing a human being has: his life. In addition to raising awareness among individuals of the danger of building houses in places with a high risk of landslides, the aim is to show that through technology we could save lives, warning about natural<br>disasters such as landslides. Originality: In this work, a previous soil survey was conducted in Ciudad Bolívar and a warning scale was created for the system, implementing the Risk Management and Climate Change Information System ( sire ) in the district. Limitations: Scarce development of rain-induced landslide warning systems in Colombia.</p> David Esneider Gutiérrez Alvis Leydy Stefany Bornachera Zarate Darin Jairo Mosquera Palacios ##submission.copyrightStatement## 2018-09-03 2018-09-03 14 26 Methodology to Update Flood Risk Areas in the Municipality of Florencia (Caquetá) Through Overflights of Remotely Piloted Aircraft <p>Introduction: This article derives from the research conducted as a graduation option in the internship at the Agustín Codazzi Geographical Institute, Caquetá office, Colombia, during the second half of 2017, supported by the Systems Engineering program at the Universidad de la Amazonia.<br>Aim: To design a methodology to update cadastral information of risk areas using a remotely piloted aircraft in the Colombian Amazonian piedmont to determine the impact caused by the phenomenon of floods.<br>Materials and methods: Two research methods were used: the first one was exploratory, based on which the sources and theoretical references for the methodology design were established.
