Influence of gender bias in the diagnosis of autism spectrum disorder: a review
2018
Resumen La prevalencia del trastorno de espectro autista (TEA) se ha incrementado en los últimos años, en parte debido a las mejoras de los métodos de detección y en parte a las modificaciones en la definición que se han ido incorporando a los manuales diagnósticos. Este incremento ha provocado que el índice de prevalencia por género sea en la actualidad de un 1,4/1, según algunos autores, o hasta de un 15,7/1 según otros, con un número muy superior de varones que reciben el diagnóstico en comparación con el número de mujeres que lo reciben. Las distintas explicaciones que se han dado a esta cuestión apuntan a unas determinadas diferencias de género en las manifestaciones sintomáticas del t…
Exploring Determinants of Early Retirement Among Saudi Medical Staff
2021
The aim of this research was to explore the relationship between the push, pull, anti-push, and anti-pull factors vs. early retirement intention among Saudi medical staff, and to investigate whether there are gender differences in the early retirement intention. To this end, we designed a correlational and cross-sectional study, for which data were collected through an online survey. A total of 680 responses were gathered, of which 221 valid responses constituted the final sample for the analysis. Logistics regression was used to test the hypotheses of the study. The results showed that approximately 58% of the respondents indicated early retirement intention. The significant factors in pre…
Economic experiments on gender behavior in financial decision making
2016
¿Son diferentes las decisiones económico-financieras de hombres y mujeres cuando se enfrentan a determinadas situaciones en entornos de riesgo y/o ambigüedad, o en entornos competitivos? En los últimos años, se ha utilizado la economía experimental para el estudio de las diferencias de género. La metodología experimental es especialmente adecuada para este tipo de análisis, puesto que permite al investigador aislar un factor de las decisiones (por ejemplo el género) y examinarlo separadamente de otros factores. Una parte de estos trabajos experimentales ha encontrado importantes diferencias de comportamiento entre hombres y mujeres (entre otros, Gneezy et al., 2003; Niederle y Vesterlund, 2…
La valorizzazione delle specificità femminili e maschili nelle pratiche scolastiche: problemi metodologico-didattici
2014
The need to partially distinguish a way to teach men and women is rooted in a philosophical anthropology that considers sex differences an enrichment. The strengthening of the sexual identity of the students and the acquisition of a proper gender identity, in a view of respecting people of the opposite sex and equal partnership, is one of the educational goals of the school. The school thus hypothesized becomes a laboratory in which everyone can build a personal identity.
Gender-related differences in men and women with ST-segment elevation myocardial infarction and incomplete infarct-related artery flow restoration: a…
2018
Introduction: Little is known about gender-related differences in ST-segment elevation myocardial infarction (STEMI) and incomplete infarct-related artery (IRA) reperfusion after primary percutaneous coronary intervention (pPCI). Aim: To evaluate gender-related differences in clinical characteristics and prognosis in patients with STEMI and incomplete IRA reperfusion after pPCI. Material and methods: From 42,752 STEMI patients hospitalized between 2009 and 2011 in Poland we analyzed a group of 984 (36%) females and 1,746 (64%) males with less than Thrombolysis in Myocardial Infarction (TIMI) grade 3 flow following pPCI. Results: Women were older than men (72.0 ±11.3 vs. 64.0 ±11.7 years; p …
Multispectral analysis and cone signal modelling of pseudoisochromatic test plates
2013
The aim of the study is to determine the consistency of the desired colour reproduction of the stimuli using calibrated printing technology available to anyone (EpsonStylus Pro 7800 printer was). 24 colour vision assessment plates created in the University of Latvia were analysed right after their fabrication on august 2012 and after intense use for 7 months (colour vision screening on 700 people). Multispectral imagery results indicate that the alignment of the samples after seven months of use has maintained on the CIExy confusion lines of deutan deficiency type, but the shift towards achromatic area in the diagram indicate decrease in the total colour difference (ΔE*ab) of test backgroun…
Estimation of the mechanical properties of the eye through the study of its vibrational modes.
2017
Measuring the eye's mechanical properties in vivo and with minimally invasive techniques can be the key for individualized solutions to a number of eye pathologies. The development of such techniques largely relies on a computational modelling of the eyeball and, it optimally requires the synergic interplay between experimentation and numerical simulation. In Astrophysics and Geophysics the remote measurement of structural properties of the systems of their realm is performed on the basis of (helio-)seismic techniques. As a biomechanical system, the eyeball possesses normal vibrational modes encompassing rich information about its structure and mechanical properties. However, the integral a…
Spectrophotometric evaluation of dental bleaching under orthodontic bracket in enamel and dentin
2013
Aware of the diffusion capacity of bleaching in the dental tissues, many orthodontists are subjecting their patients to dental bleaching during orthodontic treatment for esthetic purposes or to anticipate the exchange of esthetic restorations after the orthodontic treatment. For this purpose specific products have been developed in pre-loaded whitening trays designed to fit over and around brackets and wires, with clinical efficacy proven. Objective: The objective of this study was to evaluate, through spectrophotometric reflectance, the effectiveness of dental blea - ching under orthodontic bracket. Material and methods: Thirty-two bovine incisors crown blocks of 8 mm x 8 mm height lengths…
Temporal analysis of normalized difference vegetation index (NDVI) and land surface temperature (LST) parameters to detect changes in the Iberian lan…
2011
In past decades, the Iberian Peninsula has been shown to have suffered vegetation changes such as desertification and reforestation. Normalized difference vegetation index (NDVI) and land surface temperature (LST) parameters, estimated from data acquired by the Advanced Very High Resolution Radiometer (AVHRR) sensor onboard the National Oceanic and Atmospheric Administration (NOAA) satellite series, are particularly adapted to assess these changes. This work presents an application of the yearly land-cover dynamics (YLCD) methodology to analyse the behaviour of the vegetation, which consists of a combined multitemporal study of the NDVI and LST parameters on a yearly basis. Throughout the 1…
