PRÁCTICAS DEL ANÁLISIS FACTORIAL EXPLORATORIO (AFE) EN LA INVESTIGACIÓN SOBRE CONDUCTA DEL CONSUMIDORY MARKETING
2012
El Análisis Factorial Exploratorio (AFE) es una de las técnicas estadísticas más utilizadas en la investigación social. El principal objetivo de este trabajo es describir las prácticas más utilizadas por los investigadores en el área de la conducta del consumidor y el marketing. Mediante una metodología de revisión documental se analizan las prácticas de AFE en cinco revistas españolas dedicadas a dicha temática (2000-2010). Se analizan las elecciones de los investigadores relacionadas con el modelo factorial, el criterio de retención, la rotación, la interpretación de los factores y otras cuestiones relevantes para el análisis factorial. Los resultados sugieren que los investigadores ejecu…
Self-consistent GW calculations of electronic transport in thiol- and amine-linked molecular junctions
2011
The electronic conductance of a benzene molecule connected to gold electrodes via thiol, thiolate, or amino anchoring groups is calculated using nonequilibrium Green functions in combination with the fully self-consistent GW approximation for exchange and correlation. The calculated conductance of benzenedithiol and benzenediamine is one-fifth that predicted by standard density functional theory (DFT), in very good agreement with experiments. In contrast, the widely studied benzenedithiolate structure is found to have a significantly higher conductance due to the unsaturated sulfur bonds. These findings suggest that more complex gold-thiolate structures where the thiolate anchors are chemic…
Anticipatory autonomic response to a public speaking task in women
2002
The aim of this research was to study anticipatory autonomic responses their relationship to trait anxiety. Twenty-three women prepared an evaluated speech (S-condition) and 22 women an evaluated essay (W-condition). Heart rate (HR), finger pulse volume (FPV) and skin conductance were recorded before, during and after preparation of the task and during task performance; state-anxiety was evaluated before and after the task. In the total sample, state-anxiety was higher in the S- than in W-condition and this anxiety increase was accompanied by FPV reductions. However, when the sample was split according to trait anxiety scores, HR during preparation and increases of state-anxiety were greate…
A novel approach to CFTR mutation testing by pyrosequencing-based assay panels adapted to ethnicities.
2009
Abstract Background: Cystic fibrosis (CF) is a common autosomal recessive genetic disorder caused by a variety of sequence alterations in the CFTR gene [cystic fibrosis transmembrane conductance regulator (ATP-binding cassette sub-family C, member 7)]. Because the relative prevalence of mutations strongly depends on the ethnic background, first-level testing of CF as defined by recent consensus recommendations ought to be adaptable to the ethnicity of patients. Methods: We therefore developed and implemented a diagnostic approach to first-level testing for CF based on published mutation frequencies and Pyrosequencing (PSQ) technology that we complemented with standard procedures of mutation…
A high dietary glycemic index increases total mortality in a Mediterranean population at high cardiovascular risk
2014
© 2014 Castro-Quezada et al. Objective: Different types of carbohydrates have diverse glycemic response, thus glycemic index (GI) and glycemic load (GL) are used to assess this variation. The impact of dietary GI and GL in all-cause mortality is unknown. The objective of this study was to estimate the association between dietary GI and GL and risk of all-cause mortality in the PREDIMED study. Material and Methods: The PREDIMED study is a randomized nutritional intervention trial for primary cardiovascular prevention based on community-dwelling men and women at high risk of cardiovascular disease. Dietary information was collected at baseline and yearly using a validated 137-item food freque…
A 14-item Mediterranean diet assessment tool and obesity indexes among high-risk subjects: the PREDIMED trial
2012
Objective Independently of total caloric intake, a better quality of the diet (for example, conformity to the Mediterranean diet) is associated with lower obesity risk. It is unclear whether a brief dietary assessment tool, instead of full-length comprehensive methods, can also capture this association. In addition to reduced costs, a brief tool has the interesting advantage of allowing immediate feedback to participants in interventional studies. Another relevant question is which individual items of such a brief tool are responsible for this association. We examined these associations using a 14-item tool of adherence to the Mediterranean diet as exposure and body mass index, waist circum…
Letras de cine : tipografía queer para formar a docentes en diversidad y cultura visual
2021
En este trabajo presentamos una serie de propuestas para innovar en el ámbito de la formación de docentes desde una perspectiva crítica. Basándonos en el arte y el diseño incorporamos aspectos creativos que van desde los discursos textuales de la cultura visual (cine) o el diseño (tipografías) hasta cuestiones de diversidad sexual y disidencias queer. Impulsamos experiencias creativas introduciendo como elemento de referencia el estudio de las tipografías diseñadas para películas de temática LGTB. Revisamos la tradición tipográfica de los elementos gráficos vinculados al cine como los carteles o las cabeceras de películas. Abordamos cuestiones transversales desde una óptica multidisciplinar…

Validez estructural de un cuestionario para medir comportamientos eficaces en los equipos de trabajo
2015
Se presenta un estudio de la validez estructural del cuestionario planteado por Philip R. Harris (1995; traducción al castellano realizada por el Centro de Estudios Ramón Areces, 2001) orientado a evaluar la eficacia del comportamiento individual de las personas que trabajan en un equipo. El instrumento se aplicó a una muestra compuesta por 771 empleados pertenecientes a distintos equipos de trabajo existentes en diversas organizaciones dedicadas a la atención a la dependencia. La realización del análisis factorial exploratorio reveló una estructura factorial de tres dimensiones, etiquetadas como 'habilidades comunicativas', 'expresión emocional' y 'aceptación', que explicaba el 63.2% de la…
Enhancing mental health literacy in obsessive-compulsive disorder and reducing stigma via smartphone: A randomized controlled trial protocol.
2022
Obsessive-compulsive disorder (OCD) is a disabling disorder that can be successfully treated. However, individuals with OCD do not seek or delay seeking treatment. This delay may be explained by poor mental health literacy and stigmatizing attitudes toward OCD in community. In order to work on these variables, a gamified mental health mobile application (app) called esTOCma has been developed. The purpose of this study is to describe the protocol for a study to test the efficacy of esTOCma, increasing mental health literacy and help-seeking intention, reducing the stigmatizing attitudes and social distance suffered by people with OCD, as well as the distress associated with obsessive-compul…
