Ahlfors-regular distances on the Heisenberg group without biLipschitz pieces

2015

We show that the Heisenberg group is not minimal in looking down. This answers Problem 11.15 in `Fractured fractals and broken dreams' by David and Semmes, or equivalently, Question 22 and hence also Question 24 in `Thirty-three yes or no questions about mappings, measures, and metrics' by Heinonen and Semmes. The non-minimality of the Heisenberg group is shown by giving an example of an Ahlfors $4$-regular metric space $X$ having big pieces of itself such that no Lipschitz map from a subset of $X$ to the Heisenberg group has image with positive measure, and by providing a Lipschitz map from the Heisenberg group to the space $X$ having as image the whole $X$. As part of proving the above re…

The WHO-5 Well-Being Index – Validation based on item response theory and the analysis of measurement invariance across 35 countries.

2020

Abstract Background The five-item World Health Organization Well-Being Index (WHO-5) is a frequently used brief standard measure in large-scale cross-cultural clinical studies. Despite its frequent use, some psychometric questions remain that concern the choice of an adequate item response theory (IRT) model, the evaluation of reliability at important cutoff points, and most importantly the assessment of measurement invariance across countries. Methods Data from the 6th European Working Condition survey (2015) were used that collected nationally representative samples of employed and self-employed individuals (N = 43,469) via computer-aided personal interviews across 35 European countries. …

2021

Antecedentes El envejecimiento de la población mundial es reconocido por la Organización Mundial de la Salud (OMS) como un problema principal debido a las discapacidades y comorbilidades relacionadas con este proceso, siendo las mujeres el género más afectado. Debido al deterioro y las consecuencias asociadas al envejecimiento, la actividad física y el ejercicio han demostrado ser estrategias eficaces para reducir el impacto del envejecimiento. Sin embargo, todavía se desconoce qué tipo de programa de entrenamiento podría ser el más eficaz para revertir los cambios deletéreos relacionados con la edad en mujeres mayores. En este sentido, el tipo de intensidad del entrenamiento y la modalidad…

Creencias y convencionalismos relacionados con el consumo de tabaco en preadolescentes

2003

Con el fin de conocer las características del alumnado de 11-14 años (1°-2° ESO) participante en un Programa de Prevención de Drogodependencias y con el fin de ajustar las propuestas preventivas a las necesidades de los alumnos, se seleccionó una muestra de 5.066 escolares de ambos sexos participantes en dicho programa. Los sujetos fueron valorados en el área de consumo, en la intención de consumir, en algu¬nas creencias y convicciones respecto al consumo.Los resultados indican que si bien son los varones preadolescentes los que se inician antes y consumen más que las mujeres, sin embargo en creencias relacionadas con el consumo las diferencias, en función del sexo, tienden a disminuir y a …

Efficacy of an internet-based psychological intervention for problem gambling and gambling disorder: study protocol for a randomized controlled trial

2021

Gambling Disorder is a prevalent non-substance use disorder, which contrasts with the low number of people requesting treatment. Information and Communication Technologies (ICT) could help to enhance the dissemination of evidence-based treatments and considerably reduce the costs. The current study seeks to assess the efficacy of an online psychological intervention for people suffering from gambling problems in Spain. The proposed study will be a two-arm, parallel-group, randomized controlled trial. A total of 134 participants (problem and pathological gamblers) will be randomly allocated to a waiting list control group (N = 67) or an intervention group (N = 67). The intervention program i…

UV variability and accretion dynamics in the young open cluster NGC 2264

2015

We explore UV and optical variability signatures for several hundred members of NGC 2264 (3 Myr). We performed simultaneous u- and r-band monitoring over two full weeks with CFHT/MegaCam. About 750 young stars are probed; 40% of them are accreting. Statistically distinct variability properties are observed for accreting and non-accreting cluster members. The accretors exhibit a significantly higher level of variability than the non-accretors, especially in the UV. The amount of u-band variability correlates statistically with UV excess in disk-bearing objects, which suggests that accretion and star-disk interaction are the main sources of variability. Cool magnetic spots, several hundred de…

UV And X-Ray Emission from Impacts of Fragmented Accretion Streams on Classical T Tauri Stars

2016

According to the magnetoshperic accretion scenario, during their evo- lution, Classical T Tauri stars accrete material from their circumstellar disk. The accretion process is regulated by the stellar magnetic eld and produces hot and dense post-shocks on the stellar surface as a result of impacts of the downfalling material. The impact regions are expected to strongly radiate in UV and X-rays. Several lines of evidence support the magnetospheric accretion scenario, especially in optical and infrared bands. However several points still remain unclear as, for instance,where the complex-pro le UV lines originate, or whether and how UV and X-ray emission is produced in the same shock region. Th…
