Expand your body when you look at yourself: The role of the posture in a mirror exposure task

2018

Mirror exposure (ME) is one of the main components of the treatment of patients with eating disorders symptomatology and it has shown its effectiveness in improving several outcomes (e.g., body dissatisfaction). However, the study as to what body posture should be adopted to maximize its effectiveness has been neglected. From embodied cognition and emotion theories, the adoption of an expansive (vs. contractive) body posture has been associated with positive changes in cognitive and emotional responses. The objective of this study was to analyze the effect of adopting an expansive (vs. contractive) posture before an ME task on body-related emotions and cognitions, as well as to analyze the …

Residential Exposure to Outdoor Air Pollution during Pregnancy and Anthropometric Measures at Birth in a Multicenter Cohort in Spain

2011

Background: A growing body of research suggests that prenatal exposure to air pollution may be harmful to fetal development. We assessed the association between exposure to air pollution during pregnancy and anthropometric measures at birth in four areas within the Spanish Children’s Health and Environment (INMA) mother and child cohort study. Methods: Exposure to ambient nitrogen dioxide (NO2) and benzene was estimated for the residence of each woman (n = 2,337) for each trimester and for the entire pregnancy. Outcomes included birth weight, length, and head circumference. The association between residential outdoor air pollution exposure and birth outcomes was assessed with linear regress…

Psychometric properties, validity and insights of the School Bullying Questionnaire (CIE-A) in secondary schools of the Valencian Community (Spain)

2021

Besides its several threats to health, welfare, social and academic development and performance of kids and teenagers, school bullying remains highlighted as one of the most relevant related challenges for educational, behavioral and legal sciences worldwide. Moreover, the lack of research on the field and the crucial but unattended need to count on psychometrically suitable and valid tools to detect school bullying make difficult understanding its contexts, dynamics and possible solutions. Objective The aim of this study was to thoroughly present in detail the psychometric properties and validity issues of the School Bullying Questionnaire (CIE-A) among secondary students.

Towards a cross-cultural assessment of binge-watching : Psychometric evaluation of the “watching TV series motives” and “binge-watching engagement an…

2020

International audience; In view of the growing interest regarding binge-watching (i.e., watching multiple episodes of television (TV) series in a single sitting) research, two measures were developed and validated to assess binge-watching involvement (``Binge-Watching Engagement and Symptoms Questionnaire'', BWESQ) and related motivations (``Watching TV Series Motives Questionnaire'', WTSMQ). To promote international and cross-cultural binge-watching research, the present article reports on the validation of these questionnaires in nine languages (English, French, Spanish, Italian, German, Hungarian, Persian, Arabic, Chinese). Both questionnaires were disseminated, together with additional …

How to Become a Pediatric Surgeon?

2020

As the title of this chapter already suggests, in this chapter the path of how become a pediatric surgeon is described and important question on this issue are answered. These questions are all dealing with the process and the structure of pediatric surgery training and the requirements which are necessary to become a pediatric surgeon. In preparation of this book chapter, we performed an online survey about the organization and structure of pediatric surgery training around the world. The survey was sent to all official national admissions departments and organizations of pediatric surgery. Thus, data from 28 different countries were compiled. They serve as the basis of some of the questio…

Irradiation effects on the absorption edge of silica glass

2007

Abstract Vacuum ultraviolet absorption experiments were carried out on a variety of specimens of amorphous silica β-irradiated at different doses from ∼103 to 5 × 106 kGy. Changes in the width of the absorption (Urbach) edge were investigated. These changes strongly depend on the kind of silica considered: in particular the Urbach energy of silica of industrial manufacture increases in the irradiated samples, whereas in sol–gel silica it is poorly influenced by the irradiation. The fictive temperature of the different materials before and after irradiation was also monitored. The changes of the Urbach energy and of the fictive temperature are tentatively discussed considering the disorder d…

Accuracy of 210Pb dating in two annually laminated lake sediments with high Cs background

1997

Abstract A low-background gamma ray spectroscopy system has been used for nondestructive determination of 210Pb, 226Ra, 134Cs and 137Cs in lake sediment samples. Two Finnish sediment cores with high 137Cs activity originating from the Chernobyl accident have been analysed and dated using 210Pb. The accuracy of the 210Pb dating method was checked by varve counting of replicate samples. In one lake the 210Pb method gave similar dating results as varves, but in the other lake significant differences were detected. It was found that a high Cs concentration significantly impairs the accuracy of the 210Pb activity measurement. However, tha reliability of the dating result depends mostly on the co…

Calculated helium-broadened line parameters in the nu4 band of 13CH4

1998

International audience; Helium line-broadening coefficients for transitions in the nu4 band of 13CH4 have been calculated using a semi-classical model. This model is analogous to the one that we have used in a previous study on argon line-broadening coefficients for transitions in the nu3 band of 12CH4. For the present study, over 270 room temperature measurements were considered. The J, symmetry and fine structure dependences of the data are satisfactorily reproduced, although deficiencies of the semi-classical model are evidenced.
