Development and validation of the coach's task presentation scale: A quantitative self-report instrument
2016
Abstract Objective A major concern for coaches is the transmission of effective information in the moments before sport practice, when they communicate to players what they are supposed to do and how (Rink, 1994). The present study's main objective was to cover a gap in the sport psychology measurement field and to develop and validate a quantitative self-report instrument to measure the effectiveness of coaches' task presentation for athletes. The resulting instrument was the Escala de Presentacion de las Tareas por Parte del Entrenador (EPTE ) [Coach's Task Presentation Scale]. Design The two studies developed to validate the EPTE used a cross-sectional research design. Method Participant…

Psychometric evidence of a brief measure of resilience in non-institutionalized Peruvian older adults
2018
Resilience is understood as the domain of personal resources and contextual factors that allow for a successful coping and enhance positive adaptation to the different stressors during the lifespan, thereby being important for a healthy and successful aging. Nowadays, several brief instruments have been developed to measure resilience, such as the Brief Resilient Coping Scale (BRCS), an instrument that measures the ability of people to confront stress in an adaptive way. In this vein, the study provides evidence of the validity and reliability of the BRCS in non-institutionalized older adults in Peru. Two hundred thirty-six elderly people of both genders, 78.4% women and 21.6% men, with a m…

The Intimate Partner Violence Responsibility Attribution Scale (IPVRAS)
2014
The aim of this study is to present a psychometrically sound instrument to assess intimate partner violence offenders’ responsibility attributions: the Intimate Partner Violence Responsibility Attribution Scale. The scale was administrated to 423 adult male intimate partner violence offenders court-mandated to a community-based intervention program. A three factor structure (responsibility attribution to the legal system, responsibility attribution to the victim, and responsibility attribution to the offender personal context) was supported using confirmatory factor analysis. Reliability of the scales in this study was estimated using Cronbach’s alpha, ρ and greatest lower bound. The Intima…
The use of virtual reality as a potential restorative environment in school during recess
2020
Publisher Copyright: © 2020, Springer Nature Switzerland AG. Copyright: Copyright 2021 Elsevier B.V., All rights reserved. Previous research has found out that simulated, Virtual Reality (VR)-based forests can bring equal or even higher restorative effects than real forests. In this study, a Virtual Reality (VR)-based forest was created in order to compare whether VR-based forest can possess restorative effects in the context of primary school, and how the possible effects compare to restorative effects of a normal recess or to a situation when there is no recess at all. The effects were measured using Restorative Outcome Scale (ROS) and problem-solving tasks after the intervention. The res…
Images perceived after chromatic or achromatic contrast sensitivity losses.
2010
Purpose. We simulate how subjects with losses in chromatic and achromatic contrast sensitivity perceive colored images by using the spatiochromatic corresponding pair algorithm. Methods. This is a generalized version of the algorithm by Capilla et al. (J Opt Soc Am (A) 2004;21:176 –186) for simulating color perception of color deviant subjects, which incorporates a simple spatial vision model, consisting of a linear filtering stage, with a band-pass achromatic filter and two low-pass chromatic ones, for the red-green and blue-yellow mechanisms. These filters, except for the global scaling, are the subject’s contrast sensitivity functions measured along the cardinal directions of the color s…
Exudate Segmentation on Retinal Atlas Space
2013
International audience; Diabetic macular edema is characterized by hard exudates. Presence of such exudates cause vision loss in the affected areas. We present a novel approach of segmenting exudates for screening and follow-ups by building an ethnicity based statistical atlas. The chromatic distribution in such an atlas gives a good measure of probability of the pixels belonging to the healthy retinal pigments or to the abnormalities (like lesions, imaging artifacts etc.) in the retinal fundus image. Post-processing schemes are introduced in this paper for the enhancement of the edges of such exudates for final segmentation and to separate lesion from false positives. A sensitivity(recall)…
COVID-19 and the impact on the cranio-oro-facial trauma care in Italy:An epidemiological retrospective cohort study
2021
The coronavirus disease 2019 (COVID-19) has deeply modified the organization of hospitals, health care centers, and the patient’s behavior. The aim of this epidemiological retrospective cohort study is to evaluate if and how the COVID-19 pandemic has determined a modification in cranio-oro-facial traumatology service. Methods: The dataset included hospital emergency room access of a six-month pre-pandemic period and six months into pandemic outbreak. The variables collected were: patient age, gender, type of emergency access with relative color code, Glasgow Coma Scale Score, type of discharge. Results: 537 vs. 237 (pre-pandemic vs. pandemic) patients accessed the hospital emergency room an…
Multiscale Model Selection for High-Frequency Financial Data of a Large Tick Stock by Means of the Jensen–Shannon Metric
2014
Modeling financial time series at different time scales is still an open challenge. The choice of a suitable indicator quantifying the distance between the model and the data is therefore of fundamental importance for selecting models. In this paper, we propose a multiscale model selection method based on the Jensen–Shannon distance in order to select the model that is able to better reproduce the distribution of price changes at different time scales. Specifically, we consider the problem of modeling the ultra high frequency dynamics of an asset with a large tick-to-price ratio. We study the price process at different time scales and compute the Jensen–Shannon distance between the original…
