CAD-R. Cuestionario de afrontamiento al dolor crónico: análisis factorial confirmatorio. ¿Hay diferencias individuales en sexo, edad y tipo de dolor?
2017
espanolRESUMEN Introduccion: Se presenta una revision del CAD-R (Cuestionario de afrontamiento al dolor reducido) (1) en una muestra de 4.389 pacientes diagnosticados con dolor cronico derivada de un estudio multicentrico de toda Espana (2). Material y metodo: Se analiza la estructura factorial mediante analisis factorial exploratorio (AFE) y confirmatorio (AFC), asi como la fiabilidad (consistencia interna y test retest a los tres meses, esta ultima sobre 2.825 pacientes). Se ponen a prueba cuatro modelos constatando que las estrategias de primer orden correlacionadas son las que aportan mejores indices de ajuste. Resultados: Tanto los indices de consistencia interna como los test-retest r…
Contributo para o estudo psicométrico da versão portuguesa do Cuestionario de Satisfacción Laboral S20/23
2010
Job satisfaction is understood through its dual role on organization productivity and employees achievement (Smith, 1998). The use of instruments to measure it in Portugal, has been the subject of several studies, such as the adaptation of the Cuestionario de Satisfacción Laboral S20/23 (Meliá & Peiró, 1989) to Portuguese population carried out by Pocinho and García (2008). This study is a further contribution to the study of the psychometric qualities of this instrument. The results on a sample of 136 Portuguese employees show that the questionnaire presents the adequate requirements of internal consistency (.95), test-retest reliability, and convergent validity (correlation of .84 with th…
Comparison of the planimetry and point-counting methods for the assessment of the size of the mandible cysts on orthopantomograms
2011
Sahin, Bunyamin/0000-0001-8538-8443 WOS: 000304343300015 PubMed: 22143725 Objective: The purpose of this study is to compare the computer-assisted planimetry and point-counting methods in evaluating the sizes of the mandibular cysts with respect to their agreement and the time required to analyze. Study Design: The surface areas of 46 mandibular cyst lesions on orthopantomograms were estimated using the point-counting and computer-assisted planimetry methods. Three observers evaluated the outlined areas twice, using the point-counting (PC) and computer-assisted planimetry (CAP) methods with an interval of two weeks. In the planimetry technique, digitalized images and ImageJ software were us…
Macroscopic expressions of molecular adiabatic compressibility of methyl and ethyl caprate under high pressure and high temperature
2014
The molecular compressibility, which is a macroscopic quantity to reveal the microcompressibility by additivity of molecular constitutions, is considered as a fixed value for specific organic liquids. In this study, we introduced two calculated expressions of molecular adiabatic compressibility to demonstrate its pressure and temperature dependency. The first one was developed from Wada’s constant expression based on experimental data of density and sound velocity. Secondly, by introducing the 2D fitting expressions and their partial derivative of pressure and temperature, molecular compressibility dependency was analyzed further, and a 3D fitting expression was obtained from the calculated…
Consistency between GRUAN sondes, LBLRTM and IASI
2017
Abstract. Radiosonde soundings from the GCOS Reference Upper-Air Network (GRUAN) data record are shown to be consistent with Infrared Atmospheric Sounding Instrument (IASI)-measured radiances via LBLRTM (Line-By-Line Radiative Transfer Model) in the part of the spectrum that is mostly affected by water vapour absorption in the upper troposphere (from 700 hPa up). This result is key for climate data records, since GRUAN, IASI and LBLRTM constitute reference measurements or a reference radiative transfer model in each of their fields. This is specially the case for night-time radiosonde measurements. Although the sample size is small (16 cases), daytime GRUAN radiosonde measurements seem to h…
Multitemporal Mosaicing for Sentinel-3/FLEX Derived Level-2 Product Composites
2020
The increasing availability of remote sensing data raises important challenges in terms of operational data provision and spatial coverage for conducting global studies and analyses. In this regard, existing multitemporal mosaicing techniques are generally limited to producing spectral image composites without considering the particular features of higher-level biophysical and other derived products, such as those provided by the Sentinel-3 (S3) and Fluorescence Explorer (FLEX) tandem missions. To relieve these limitations, this article proposes a novel multitemporal mosaicing algorithm specially designed for operational S3-derived products and also studies its applicability within the FLEX…
PATRONES DIFERENCIALES ENTRE PADRES Y PROFESORADO EN LA DETECCIÓN DE TDAH
2015
INTRODUCTION . The diagnosis of Attention Deficit Disorder with Hyperactivity (ADHD) has increased in recent years. The criteria for ADHD have become clearer in the scientific community. However, it is a complex disorder that requires the participation of a multidisciplinary team for an appropriate diagnosis. METHOD . Taking as a sample (N = 331) 6 to 9 year-old students from Cuenca, this study analyzed the existence of differential patterns between the two ratings, using the EMA-D.D.A. Scales (Garcia-Perez y Magaz, 2006). Different approaches to hypothesis testing are used, and the internal consistency of the scales is valued. RESULTS . The differences observed suggest differential influen…
Actitudes hacia el alumnado con discapacidad en educación física: validación de la EAADEF-EP a la etapa de educación primaria
2020
La investigación que aborda la inclusión del alumnado con discapacidad en educación física (EF) se presenta como un reto educativo en la actualidad. El objetivo de este estudio fue validar la Escala de Actitud hacia el Alumnado con Discapacidad en Educación Física (EAADEF) de Íñiguez-Santiago et al. (2017) a la etapa de educación primaria (EAADEF-EP). Participaron 465 estudiantes (rango 9-13 años) que cursaban 4º, 5º y 6º curso de la etapa de educación primaria obligatoria (EPO). Se confirmaron unos índices de ajuste adecuados para la adaptación de la EAADEF a EPO, mostrándose la estructura factorial invariante respecto al curso, género, el contacto previo con familiares o amigos con discap…
Internal consistency predicts attractiveness in biological motion walkers
2016
Abstract Why do some people appear attractive to us while others don't? Evolutionary psychology states that sexual attractiveness has evolved to assess the reproductive qualities of a potential mate. Past research in the field has identified a number of traits that can be linked directly to qualities such as immuno-competence, developmental stability, and fertility. The current study is motivated by the hypothesis that attractiveness is determined not just by individual, independent traits, but also by whether their pattern is internally consistent. Exploiting the domain of biological motion, we manipulated internal consistency between anthropometry and kinematics of a moving body. In two e…
Autocorrelation Metrics to Estimate Soil Moisture Persistence From Satellite Time Series: Application to Semiarid Regions
2021
Satellite-derived soil moisture (SM) products have become an important information source for the study of land surface processes in hydrology and land monitoring. Characterizing and estimating soil memory and persistence from satellite observations is of paramount relevance, and has deep implications in ecology, water management, and climate modeling. In this work, we address the problem of SM persistence estimation from microwave sensors using several autocorrelation metrics that, unlike traditional approaches, build on accurate estimates of the autocorrelation function from nonuniformly sampled time series. We show how the choice of the autocorrelation estimator can have a dramatic impac…
