Polymer meshes have recently attracted great attention due to their great variety of applications in fields such as tissue engineering and drug delivery. Poly(-caprolactone) nanofibers were prepared by electrospinning giving rise to porous meshes. However, for some applications in tissue engineering where, for instance, cell migration into the inner regions of the mesh is aimed, the pore size obtained by conventional techniques is too narrow. To improve the pore size, laser irradiation with femtosecond pulses (i.e., negligible heat diffusion into the polymer material and confined excitation energy) is performed. A detailed study of the influence of the pulse energy, pulse length, and number of pulses on the topography of electrospun fiber meshes has been carried out, and the irradiated areas have been studied by scanning electron microscopy, contact angle measurements and spectroscopic techniques. The results show that using the optimal laser parameters, micropores are formed and the nature of the fibers is preserved.
El trabajo propone un modelo para cultura organizacional con la inclusión de variables del salario emocional; para ello, se parte de la revisión de la literatura, se plantean las preguntas de investigación que derivan en un conjunto de hipótesis que contemplan la influencia de las variables: oportunidades de desarrollo, balance de vida, cultura laboral, beneficios psicológicos, entorno laboral sobre la cultura organizacional. Las relaciones de las hipótesis conforman un modelo de ecuaciones estructurales, el mismo que es sujeto a instancia de prueba con un tamaño muestral de 210 empleados del área administrativa de la Universidad Católica de Cuenca (UCACUE) en Ecuador. Los resultados demuestran la influencia sobre la cultura organizacional de las variables: bienestar psicológico y cultura laboral con alto grado de significancia, balance de vida con grado medio y con bajo nivel el entorno laboral y oportunidad de desarrollo. El instrumento aplicado es estadísticamente válido y confiable y las hipótesis son soportadas, por tanto, la Universidad Católica de Cuenca, manifiesta interés en el bienestar y satisfacción de su personal, para ello requiere mejorar sus estrategias de motivación a través de la implementación del salario emocional.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
