Evaluating free school fruit: results from a natural experiment in Norway with representative data
2014
AbstractObjectiveTo assess impacts of the nationwide Norwegian School Fruit Scheme (NSFS) using nationally representative data.DesignThe NSFS is organized such that primary-school children (grades 1–7) are randomly assigned to one of three school fruit arrangements: (i) the child receives one free fruit or vegetable per day; (ii) the child is given the option to subscribe to one fruit or vegetable per day at a subsidized price; and (iii) the child attends a school that has no school fruit arrangement.SettingData from an Internet survey are used to compare child and parental fruit and vegetable intakes across the three NSFS groups focusing mainly on groups (i) and (iii). The analysis was con…
Validation and reproducibility of dietary assessment methods in adolescents: a systematic literature review.
2013
AbstractObjectiveThe aim of the present work was to determine what dietary assessment method can provide a valid and accurate estimate of nutrient intake by comparison with the gold standard.DesignA MEDLINE, EMBASE, ISI Web of Science, Cochrane and related references literature review was conducted on dietary assessment methods for adolescents reporting the validity and/or reproducibility values. A study quality assessment on the retrieved FFQ was carried out according to two different scoring systems, judging respectively the quality of FFQ nutrition information and of FFQ validation and calibration.SettingThe present review considered adolescents attending high schools and recruited in ho…
Persistence of symptoms in primary somatoform vertigo and dizziness: a disorder "lost" in health care?
2013
The aim of this study was to perform a 3-year follow-up of primary somatoform vertigo and dizziness (SVD) regarding health care use and treatment. Ninety-two patients with dizziness underwent detailed vestibular neurophysiological testing and a Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. Psychometric assessments comprised the Vertigo Symptom Scale, the Vertigo Handicap Questionnaire, the SCL-90-R, and the Short-Form-36 Health Survey. At the 3-year follow-up, 65 patients with primary SVD (anxiety, n = 29; depression, n = 14; somatoform disorders, n = 22) were reassessed (70.7% response). The patients improved in symptom severity (p…
A Study of Gravitational Lens Chromaticity with the Hubble Space Telescope
2011
We report Hubble Space Telescope observations of 6 gravitational lenses with the Advanced Camera for Surveys. We measured the flux ratios between the lensed images in 6 filters from 8140\AA\ to 2200\AA. In 3 of the systems, HE0512$-$3329, B1600+434, and H1413+117, we were able to construct UV extinction curves partially overlapping the 2175\AA\ feature and characterize the properties of the dust relative to the Galaxy and the Magellanic Clouds. In HE1104$-$1804 we detect chromatic microlensing and use it to study the physical properties of the quasar accretion disk. For a Gaussian model of the disk $\exp(-r^2/2 r_s^2)$, scaling with wavelength as $r_s \propto \lambda^p$, we estimate $r_s(\l…
The Chandra COSMOS Survey, I: Overview and Point Source Catalog
2009
The Chandra COSMOS Survey (C-COSMOS) is a large, 1.8 Ms, Chandra} program that has imaged the central 0.5 sq.deg of the COSMOS field (centered at 10h, +02deg) with an effective exposure of ~160ksec, and an outer 0.4sq.deg. area with an effective exposure of ~80ksec. The limiting source detection depths are 1.9e-16 erg cm(-2) s(-1) in the Soft (0.5-2 keV) band, 7.3e(-16) erg cm^-2 s^-1 in the Hard (2-10 keV) band, and 5.7e(-16) erg cm(-2) s(-1) in the Full (0.5-10 keV) band. Here we describe the strategy, design and execution of the C-COSMOS survey, and present the catalog of 1761 point sources detected at a probability of being spurious of <2e(-5) (1655 in the Full, 1340 in the Soft, and…
Management and Outcome of Mucosal Injury During Pyloromyotomy--An Analytical Survey Study.
2015
Different approaches of dealing with mucosal injury during pyloromyotomy for hypertrophic pyloric stenosis have been described. There is, however, no consensus on the best technique to use. We conducted a survey among International Pediatric Endosurgery Group (IPEG) members on their experience of mucosal injuries during pyloromyotomy, the way in which these were handled, any modification in subsequent postoperative care, and impact on outcome.A confidential survey was sent to IPEG members querying demographic data, number of pyloromyotomies performed, operative approach, incidence of mucosal injury, intraoperative management, and postoperative consequences. Statistical analysis was performe…
Modern health worries and idiopathic environmental intolerance.
2008
Abstract Objective We conducted two studies to test whether modern health worries (MHWs) were associated with central features of a condition called idiopathic environmental intolerance (IEI) and medical care utilization. Methods In Study 1, 474 Internet users completed an Internet-based questionnaire that assessed MHWs, IEI features, and medical care utilization. In Study 2, the diagnostic specificity of MHWs was investigated by comparing the level of MHWs of three diagnostic groups: 46 people with IEI, 38 people with somatoform disorder but without IEI, and 46 people with neither IEI nor somatoform disorder. Results The good psychometric properties of the MHW scale were confirmed. MHWs we…
Evolution et structure des compétences des élèves à l'école élémentaire et au collège : une analyse empirique des évaluations nationales
2006
Il s'agit de la synthèse du rapport final en réponse à l'appel d'offres : Maîtrise du langage, diversité des pratiques pédagogiques et socle commun de compétences, pour le Centre Henri Aigueperse, UNSA-Education. La recherche, basée en grande partie sur l'analyse des résultats des élèves aux évaluations nationales, a pour objectif principal de mieux comprendre comment les acquisitions scolaires se structurent dans une double perspective : transversale (à un moment donné de la scolarité) et longitudinale (au cours des cycles d'enseignement). Dans cette optique, des données ont été collectées sur un échantillon d'environ 700 élèves originaires d'une même circonscription scolaire à différents …
Integrating Virtual Realities and Psychotherapy: SWOT Analysis on VR and MR Based Treatments of Anxiety and Stress-related Disorders
2021
© 2021 The Author(s). Published by Informa UK Limited, trading as Taylor & Francis Group.The use of virtual reality (VR) and mixed reality (MR) technology in clinical psychology is growing. Efficacious VR-based treatments for a variety of disorders have been developed. However, the field of technology-assisted psychotherapy is constantly changing with the advancement in technology. Factors such as interdisciplinary collaboration, consumer familiarity and adoption of VR products, and progress in clinical science all need to be taken into consideration when integrating virtual technologies into psychotherapies. We aim to present an overview of current expert opinions on the use of virtual…
