The continuous sample of working lives: Improving its representativeness
2017
This paper studies the representativeness of the Continuous Sample of Working Lives (CSWL), a set of anonymized microdata containing information on individuals from Spanish Social Security records. We examine several CSWL waves (2005–2013) and show that it is not representative for the population with a pension income. We then develop a methodology to draw a large dataset from the CSWL that is much more representative of the retired population in terms of pension type, gender and age. This procedure also makes it possible for users to choose between goodness of fit and subsample size. In order to illustrate the practical significance of our methodology, the paper also contains an applicatio…
Anodic Electro Deposition of CeO2 and Co-Doped CeO2 Thin Films
2013
CeO2 and Co containing CeO2 thin films were deposited on indium tin oxide and stainless steel by anodic electrodeposition. Scanning electron microscopy showed that the films are flat and show globular morphology and cracks resulting from volume shrinking. According to XRD and Raman Spectroscopy pure ceria layers are crystalline, while the presence of Co induces the formation of amorphous films. The good adhesion and the compactness allowed the photoelectrochemical characterization of the films. A band gap value of 2.9 eV was estimated for CeO2, while slightly higher values (̃3.0 eV) were estimated for Co containing films. A mechanism for ceria anodic electrodeposition is proposed and discus…
Band Gap Modeling of Different Ternary and Quaternary Alumina Garnet Phases Y3(AlXGa1-X)5O12 (YAGG) and Lu3(AlXGa1-X)5O12 (LuAGG). A Semiempirical Ap…
2022
A further generalization to quaternary oxide systems of the modeling equation of optical band gap values, based on the semiempirical correlation between the differences in the electronegativity of oxygen and the average cationic electronegativity, proposed some years ago, has been carried out by expanding the approach recently employed for ternary mixed oxides. The choice of oxide polymorphs and their influence on the fitting procedure of an experimental data set is evidenced by a detailed discussion of the fitting process of the literature's experimental band gap data pertaining two quaternary oxide systems of the garnet family, namely, Y3(AlxGa1-x)5O12 (YAGG) and Lu3(AlxGa1-x)5O12 (LuAGG)…
Fallacies about p-Value Shared by Professors and University Students
2017
Resumen La “Práctica Basada en la Evidencia” requiere a los profesionales valorar de forma crítica los resultados de las investigaciones psicológicas. Sin embargo, las interpretaciones incorrectas de los valores p de probabilidad son abundantes y repetitivas. Estas interpretaciones incorrectas pueden afectar las decisiones profesionales y poner en riesgo la calidad de las intervenciones y la acumulación de un conocimiento científico válido. Por lo tanto, identificar el tipo de falacia que subyace a las decisiones estadísticas es fundamental para abordar y planificar estrategias de educación estadística dirigidas a intervenir sobre las interpretaciones incorrectas. En consecuencia, el objeti…
Valor da relação, compromisso, TIC e lealdade no canal de comercialização
2009
En el actual contexto empresarial altamente competitivo, gran número de organizaciones tienden a reducir el número de proveedores para centrarse en establecer relaciones estrechas y duraderas con un número reducido de ellos. Si bien las tecnologías de la información y la comunicación (TIC) ofrecen grandes ventajas en las relaciones entre empresas, el vínculo entre la inversión en dichas tecnologías y el valor de la relación no es claro. En el presente trabajo pretendemos analizar la influencia del uso de diversas aplicaciones tecnológicas del proveedor sobre el valor de la relación, el compromiso y la lealtad hacia el mismo desde el punto de vista de la empresa cliente. A través de la estim…
