Ítem Barriers and success factors in lean construction implementation-survey in pilot context(Lean Construction, 2015-07-31) Cano, Sandra; Botero- B, Luis-F; Delgado, Jonathan; RUBIANO, OSCAR; Universidad EAFIT. Departamento de Ingeniería Civil; Gestión de la ConstrucciónThe study identifies a set of barriers and critical success factors (CSF) involved in the implementation of Lean Construction (LC) through three phases: Literature's Collection, with analysis and obtained information processingÍtem Impacto de la producción de café en las condiciones de vida en los municipios del departamento de Antioquia en el periodo de tiempo de 2011-2017(Universidad Eafit, 2020) Saldarriaga Pareja, Juan Camilo; España Eljaiek, IrinaA panel database was used at the municipal level for the period 2011-2017, obtained from the Agronet and Terridata information sources from the Ministry of Agriculture and Rural Development (MADR) and the National Planning Department (DNP) respectively. With these data, synthetic indicators of living conditions were constructed from the factor analysis to evaluate the impact that coffee production had on the living conditions of coffee municipalities in the department of Antioquia. Through a fixed effects model, the estimation is made and positive evidence is found of the impact that coffee activity has on health and education conditions. The findings are subject to endogeneity due to variables omitted due to the lack of available information, however, they are in line with other studies developed on the subject.Ítem Implementación de Lean Manufacturing en el sector hotelero de la ciudad de Medellín(Universidad EAFIT, 2015) Arango Uribe, Juliana María; Arrieta Posada, Juan GregorioEl sector hotelero en la ciudad de Medellín ha tenido un crecimiento significativo en los últimos años, registrando uno de los mejores momentos históricos en ocupación hotelera, motivo por el cual surge el interés por evaluar el sector -- Este proyecto busca evaluar el grado de implementación de Lean Manufacturing en diferentes hoteles ubicados en la ciudad de Medellín, para la investigación se desarrolló un cuestionario, el cual fue aplicado a una muestra de hoteles -- Del cuestionario se obtienen los hoteles destacados en implementaciones Lean Manufacturing, posteriormente se analizan los mismos hoteles mediante un análisis envolvente de datos (DEA) con el fin de encontrar similitudes o disimilitudes entre ambos métodos de evaluaciónÍtem Invarianza del Cuestionario de Dependencia Emocional entre sexos y situación sentimental en universitarios(PONTIFICIA UNIV CATOLICA PERU, 2019-01-01) Lemos, M; Vasquez-Villegas, C; Roman-Calderon, JPThis work aimed to explore the factorial structure and the measurement invariance between groups of the emotional dependence questionnaire (EDQ). Participants included a random sample of 569 university students, 67.8% women and 51.2% had a romantic partner. The multigroup confirmatory factor analysis (MG-CFA) showed metric invariance for the EDQ. Particularly, the findings indicate that five of six scales of the questionnaire have an average variance extracted higher than 53% and a composite reliability of more than 0.75; the borderline expression scale was excluded. It was found that the EDQ has a strong measurement invariance degree between genders, ?2(365) = 750.14, p<.05; RMSEA= .07; CFI= .92; TLI= .92; and the presence of a partner, ?2(365) = 750.30, p<.05; RMSEA= .06; CFI= .92; TLI= .92. © 2019 Pontificia Universidad Catolica del Peru.

Although there are many models and definitions of UX, most of them have been proposed intuitively. From themes and elements previously identified as essential for an UX model, a study of exploratory factor analysis (EFA ) was performed. We found eight factors in Before-UX-stage, 7 in During-UX and 17 in After-UX stage. Similar UX aspects are expressed in different ways trough the different stages and factors. There are differences in terms of how a factor could weight and relate to others regarding the UX-stage. Moreover, while some factors are consistent with the literature, others are new. Most of the factors give us an idea about the articulation of variables and the way some factors relate to others.
