Metodología de la Investigación Cualitativa

López-Belmonte, Jesús

Este material ofrece una introducción sistemática y aplicada a la metodología de la investigación cualitativa, entendida como un enfoque orientado a comprender experiencias, significados, prácticas, procesos y contextos sociales complejos. Presenta sus fundamentos epistemológicos, las diferencias respecto a la investig...

Empowering Rural Women for Food Security: Evidence from Pig Production in Post-Conflict Colombia

Leidy Ortiz-Araque · Ingrid Quintana-Leal · Sandra Montesino-Rincón · Ana Salazar-Beleño · y 1 más

Female empowerment in post-conflict rural contexts is strategic for food security and socioeconomic resilience. This study analyzed the relationship between women’s productive empowerment and food security in 40 rural women involved in pig production in Santa Rosa del Sur, Bolívar, Colombia. A mixed approach with a des...

The shape of evolution: persistent homology of genetic-distance data as an observable of reticulate processes in pathogen and plant genomes

Alejandro Feged-Rivadeneira · Felipe González-Casabianca · Pablo Cárdenas Ramírez · Andrés Ángel · y 1 más

Abstract Evolutionary biology has long theorized processes—recombination, lineage divergence, drug-resistance sweeps, introgression, refugial persistence—whose signatures in genomic data are incompatible with tree structure. We argue that the shape of genetic-distance data, formalized through simplicial complexes and q...

Hybrid Ant Lion Optimization Methodology for Network Reconfiguration and Optimal Placement of Distributed Generation Considering Short-Circuit Constraints

Andrés Fernando Torres-Valenzuela · Edgar E. Tibaduiza-Rincón · Jesús M. López-Lezama

The increasing penetration of distributed generation (DG) in distribution systems poses significant operational challenges, including increased power losses, voltage profile deviations, and variations in short-circuit currents. These issues may compromise network safety, reliability, and the selectivity of protection s...

Comparative Life Cycle Assessment of Physical and Chemical Activation Routes for Oil Palm Shell-Derived Activated Carbon in Lufenuron 50-EC Pesticide Adsorption

David Nuñez-Vargas · Juan Barraza-Burgos · Luis Díaz · Ajay K. Dalai · y 2 más

This study evaluates the life cycle assessment (LCA) of Lufenuron 50-EC pesticide adsorption from aqueous solution using oil palm shell (OPS)-derived activated carbon produced through two activation routes: physical and chemical. The assessment covers environmental impacts associated with feedstock collection, transpor...

Multi-Element Exposure in a High-Altitude Páramo Mining District and Oxidative Stress Biomarkers in Gold Miners

Lyda Espitia-Pérez · Luz Helena Sánchez Rodríguez · Hugo Brango · Pedro Espitia-Pérez · y 3 más

Artisanal and small-scale gold mining (ASGM) generates complex metal mixtures, yet their biological effects remain poorly characterized in high-altitude populations, where occupational exposure occurs against a hypoxic environmental background. This study evaluated 49 occupationally exposed gold miners from the Vetas–C...

Exploring the Self-Perception of Complex Thinking Among International Master’s Students at a Japanese University

José Carlos Vázquez-Parra · Chris Blakely · Jenny Paola Lis-Gutiérrez · Arantxa Lucero Ramos-Huerta · y 1 más

This study examines complex thinking as a higher-order cognitive competence in international graduate education. Drawing on Edgar Morin’s theoretical perspective, it analyzes how master’s students perceive this competence through four interrelated dimensions: systemic, scientific, critical, and innovative thinking. A t...
