Aproximaciones a la medición de confianza MIGUEL DAVID ROJAS LOPEZ SANDRA PATRICIA MARIN Ingeniería Confianza Capital social Este trabajo muestra una forma de medir una variable cualitativa como es la confianza en términoscuantitativos para encontrar la relación con la construcción del capital social en la Facultad de Minas de laUniversidad Nacional de Colombia.Inicialmente se diseñó una encuesta para observar la relación de confianza entre compañeros, estudiantesprofesory alumnos con la institución. La información recopilada se analizó y se obtuvo las conclusiones queaparecen al final de este documento. 2006 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49615016 es http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.150 Vol.73
