Ítem Análisis departamental de los factores productivos y su influencia en los cultivos transitorios en Colombia para el 2022(Universidad EAFIT, 2024) García Guette, David Mauricio; Chacón Indaburo, María Fernanda; Zuluaga Orrego, Juan FernandoThis research determines the main productive factors that influenced the production of transitional crops in the departments of Colombia for 2022. We establish the importance of these to improve the conditions of Colombian agriculture through the prioritization of the most important productive factors in this type of crops, contributing to analytical mechanisms that allow a better articulation of the actors in the territories where transitional crops predominate. The analytical development made it possible to establish through a mixed methodology within which the sequential use of statistical techniques such as the Lasso regression model, Stepwise Regression and Random Forest stands out that access to land and financing were the most significant elements in the production of transitional crops for 2022 with 75.2% 15.4% respectively. The study suggests that these factors be prioritized for the articulation of actors and the prioritization of public goods for productivity and territorial development in the departments of Colombia.Ítem Diseño de un mecanismo alternativo de subasta en mercados oligopólicos para el proceso de negociación de medicamentos de alto costo(Universidad EAFIT, 2024) Castrillón Sosa, Fabricio Esteban; Chaparro Cardona, Juan CamiloÍtem Ecuación de salarios del mercado laboral del sector TIC y análisis de su brecha salarial internacional, durante el periodo 2017 - 2023(Universidad EAFIT, 2024) Quinchía Vásquez, Eliana María; Chaparro Cardona, Juan CamiloÍtem Transferencias monetarias y acceso a crédito : el caso del programa Ingreso Solidario en Colombia(Universidad EAFIT, 2024) Betancur Téllez, Sebastián; Álvarez Franco, Pilar Beatriz; Cruz Castañeda, VivianÍtem Capacidades de gestión en relación con la innovación y productividad total de los factores en el sector manufacturero en Colombia(Universidad EAFIT, 2024) González Grajales , Samfir; Gómez Sánchez, Diego FernandoÍtem Evaluación de impacto del programa Juventud Manizaleña 2022-2023, en el rendimiento académico de estudiantes de noveno grado de diferentes instituciones educativas públicas de Manizales y Caldas(Universidad EAFIT, 2024) Camargo Amezquita, Ricardo Andrés; Hernández Flórez, MónicaÍtem Concentración de mercado en el sector retail y análisis situacional de los supermercados independientes en Pereira y Dosquebradas(Universidad EAFIT, 2024) Quintero Varela, Santiago; Atis Ortega, Karen LisethÍtem La accidentalidad vial permeada por el auge de la construcción habitacional(Universidad EAFIT, 2023) Robledo Sánchez, Leonardo; Ceballos Arias, Luz Maribel; Sánchez Saldarriaga, Andrés FelipeÍtem Análisis de los programas de adulto mayor en Sabaneta y sus beneficios en la salud física, cognitiva y psicológica(Universidad EAFIT, 2023) Sánchez Henao, Natalia; Jiménez Londoño, Laura María; Ceballos García, Grey YulietÍtem Implementación de la Unidad Municipal de Atención y Acceso a la Justicia(Universidad EAFIT, 2023) Piedrahita Londoñoño, Wilfer Alonso; Atehortua Osorio, Mariano de Jesús; Murcia Sánchez , David RicardoÍtem Trading for a Cleaner Future : Carbon Markets and Colombia’s Pursuit of NDC Goals(Universidad EAFIT, 2023) Múnera-Alzate, Carlos Felipe; González-Pérez, María AlejandraÍtem Evaluación de impacto a la estrategia "Computadores futuro" en la tasa de reprobación de estudiantes de instituciones educativas oficiales de Medellín beneficiados con un computador en 2022(Universidad EAFIT, 2023) Martínez Puerta, Jhon Esteban; Puerta Álvarez, Henry Daniel"Computadores Futuro” is a program by the Medellín City Hall aimed at enhancing educational persistence by providing technological devices to students from official educational institutions in Medellín. The goal is to equip them with relevant skills for the Fourth Industrial Revolution. The primary research question was: What is the impact of the “Computadores Futuro” policy on the failure rate of Medellín students during the year 2022? Using the Propensity Score Matching methodology, the impact of this policy was assessed under four different sample restrictions. The findings indicate that, across all considered models, the policy effectively contributed to a reduction in failure rates, with observed effects ranging between 1.3% and 3.8%, depending on the specific characteristics of each sample restriction. That is, students who received a computer in 2022 exhibited up to a 3.8% reduction in the likelihood of failing compared to the hypothetical situation of not having received such computing equipment. It's important to note that, across all models, the observed impact was statistically significant at the 1% level, confirming the effect of the intervention concerning the repetition rate of the benefited students. An additional and relevant finding is the relationship between connectivity and academic performance. In Model 3, it was observed that having internet access reduces the probability of failure; similarly, in Model 4, lacking connectivity increases this probability, underscoring the importance of connectivity in students' academic outcomes.Ítem Evaluación de impacto del Programa de Alimentación Escolar – PAE del municipio de Sabaneta en el período de 2020 - 2023(Universidad EAFIT, 2023) Cuartas Ochoa, Deisy Alexandra; Trujilo Gil, Johny Alexander; Ríos Agudelo, Yohan SebastianÍtem Exploración previa de los posibles efectos de la modernización del sistema de videovigilancia de Sabaneta, Antioquia(Universidad EAFIT, 2023) Montoya Montoya, Santiago; Naranjo Velásquez, María Paulina; Vasco Montoya, Nelson Leonardo; Herrera de la Hoz, César EnriqueÍtem Análisis del mercado turístico en Medellín: una aproximación desde el análisis descriptivo(Universidad EAFIT, 2023) Mesa García, Esteban; Jaramillo Vélez, Ricardo; Ospina Londoño, MónicaThe tourism market in Medellín has undergone significant changes in recent years. It is possible to observe a considerable increase in tourist demand, which in turn has been accompanied by a shift in supply, as the market seeks to respond to the new characteristics of the demand. This paper provides an overview of the tourism market, evaluating variations in supply and demand based on the descriptive analysis of available data on foreign arrivals, hotel occupancy, the Airbnb market, digital nomads, employment, rental prices, and other relevant factors to understand the change in behavior of this market. We find that there has been a shock in demand post-pandemic, which results in a shift in the demand curve due to changes in tourist preferences, partly due to the devaluation of the peso, which favors the arrival of foreign tourists. As for the supply, we find that there was an increase in registrations in the National Tourism Registry in the city, the number of available beds increased, and the income from Airbnb increased significantly.Ítem Trust in police, the relationship with victimization, the Latin American case(Universidad EAFIT, 2023) Chinkousky Giraldo, María Antonia; Sangnier, Marc; Gómez Toro, CatalinaÍtem Los efectos del saneamiento básico en el desarrollo local de las comunidades : un metaanálisis para comprender las realidades de nuestro país y territorios(Universidad EAFIT, 2023) Banguero Moreno, Carlos Alberto; Cantet, María NataliaIs there a correlation between basic sanitation and community development? A general perception is that basic sanitation is related to community development; However, there is still insufficient quantitative information to support this hypothesis and to allow considerations of the true effects of sanitation on the development of communities, so the objective of the work is to determine if there is a direct relationship between basic sanitation and community development, through a quantitative review – meta-analysis at the global level. R² determination coefficients were collected along with scale moderators, population, zone type and control type. After the review of 3003 articles, about 63 data were obtained from 15 sources. Most of them are scientific articles, with the theme occupational environmental public health and the United States being the country with the most publications. Statistical analyses determined that basic sanitation and community development are positively correlated in the world's population centers, indicating that advances or setbacks in sanitation processes such as drinking water, sewerage influence the development of communities. The great variability between studies is mainly explained by the scale (local, regional and local) which means that the level of connection between these two variables may be stronger or weaker if the evaluation changes the spatial scale. On the other hand, to materialize the positive impacts of sanitation in the municipality of Apartadó, a strategy must be generated that allows the updating of the municipal structure that responds to the new dynamics of development. In general, we can affirm that sanitation has a fundamental impact on development, since it generates an impact on environmental, economic and social aspects, and is a political challenge since it depends on the decisions and public policies that are designed in local, regional and national governments and administrations. Keywords: Sanitation, basic sanitation, drinking water, wastewater management, wastewater disposal, solid waste management, solid waste disposal.Ítem Mecanismos para la remuneración de los Recursos Energéticos Distribuidos (DER) para su incorporación en el mercado eléctrico colombiano(Universidad EAFIT, 2023) Pérez Orozco, Diana María; García Rendón, John JairoÍtem Impacto de la construcción de vivienda en la demanda del cemento en Colombia (2010 – 2022)(Universidad EAFIT, 2023) Builes Aristizábal, Laura; Puerta Álvarez, Henry Daniel; Romero Rios, NataliaÍtem Importancia del uso del e-commerce para el desempeño de los micronegocios en las principales ciudades de Colombia(Universidad EAFIT, 2023) Gómez De Las Salas, Andrea Carolina; Cao, Qiuyi; Acosta Mejía, Camilo AndrésThis paper analyzes the relationship between the use of E-Commerce by Colombian microbusinesses and their performance , especially in the main cities of the country. We use Data from DANE's Emicron for 2019 and 2021, which is a nationally representative survey about microbusinesses among 24 main cities in the country. This survey covers 86,969 microbusinesses for the year 2019 and 77,156 for 2021, which is equivalent to 11,654,842 observations when using the sample expansion factors. The results of the estimated regressions confirm the positive correlation between the use of E-Commerce and the sales and profits of microbusinesses in Colombia. Among all the companies in our study, the use of E-Commerce is associated with higher sales and profits of the previous year on average of 19.5%.
