The Relationship Between the Burnout Syndrome Dimensions and Body Mass Index as a Moderator Variable on Obese Managers in the Mexican Maquiladora Ind…
2021
Burnout syndrome (BS) and obesity are two growing conditions that affect employees’ health and company productivity. Recently, several studies have pointed to a possible relationship between both phenomena. However, such a relationship has not been clearly defined. This research analyzes the relationship between BS dimensions and body mass index (BMI), the latter being treated as a moderator variable among obese senior and middle managers in the Mexican maquiladora industry through a structural equation model. A total of 361 senior and middle managers (124 of them classified as obese under the World Health Organization’s criteria) completed both the Maslach Burnout Inventory-General Survey …
Melatonin Concentrations and Sleep Quality in Patients with Type 2 Diabetes and Obesity
2019
Abstract There is a close relationship between melatonin as a circadian regulator and insulin, glucagon and somatostatin production. This study aimed to describe subgroups of type 2 diabetes mellitus (T2DM) patients that may benefit from melatonin clock-targeting properties. The study involved 38 participants: 26 T2DM patients, and 12 participants without diabetes in the control group. Subjects were asked to complete the questionnaire of Pittsburgh Sleep Quality Index (PSQI). Standard biochemical venous sample testing was performed, and a sample of saliva was collected for melatonin testing. Melatonin concentration in participants without obesity (body mass index (BMI) < 30 kg/m2) was si…
Fundamental movement skill proficiency and body composition measured by dual energy X-ray absorptiometry in eight-year-old children
2014
Objective: The main aim was to examine the association between fundamental movement skills (FMS) and objectively measured body composition using dual energy X-ray absorptiometry (DXA). Methods: Study of 304 eight-year-old children in Finland. FMS were assessed with the Test of Gross Motor Development, 2nd ed. (TGMD-2). Total body fat percentage (BF%), abdominal region fat percentage (AF%), and fat-free mass (FFM) were assessed by DXA. Waist circumference, height and weight were measured and International Obesity Task Force (IOTF) cut-off values for BMI were used for the definition of healthy weight and overweight/obesity. Results: Better FMS proficiency (object-control, locomotor, total FMS…
The Effectiveness of Physical Activity-Promoting Web- and Mobile-Based Distance Weight Loss Interventions on Body Composition in Rehabilitation Setti…
2022
Background: Overweight and obesity are major problems worldwide, and they lead to an increased risk for several diseases. The use of technology in the treatment of obesity is promising, but in the existing literature, there is considerable uncertainty regarding its efficacy. In this review, we included web- and mobile-based weight loss interventions that were implemented remotely in rehabilitation settings. Objective: The aim of this systematic review is to study the effectiveness of physical activity-promoting web- and mobile-based distance weight loss interventions in rehabilitation settings on body composition in comparison with control groups that did not use technology. Methods: Studie…
Gaia-ESO Survey: Cha I members
2017
Investigating the physical mechanisms driving the dynamical evolution of young star clusters is fundamental to our understanding of the star formation process and the properties of the Galactic field stars. The young (~2Myr) and partially embedded cluster Chamaeleon I is one of the closest laboratories to study the early stages of star cluster dynamics in a low-density environment. The aim of this work is to study the structural and kinematical properties of this cluster combining parameters from the high-resolution spectroscopic observations of the Gaia-ESO Survey with data from the literature. Our main result is the evidence of a large discrepancy between the velocity dispersion ({sigma}_…
The odour of human milk: Its chemical variability and detection by newborns
2019
International audience; Human milk odour has for long elicited research interest with regard to its function in breastfeeding initiation. The present review aims to provide an overview of the behavioural effects of human milk odour in the human neonate, considering different types of response measures in a feeding or non-feeding context. Further, an overview of the current knowledge of odorant composition and factors influencing milk odour is provided by summarizing results from analytical studies using olfactometry, and addressing changes in milk odour due to storage, lactational stage, and maternal dietary intake of odorous substances. We finally highlight some issues for future research.
Sistemi di tariffe di cubatura per le fustaie di pino d'Aleppo, pino laricio e pino domestico della Sicilia
2009
Obiettivo del presente lavoro e la messa a punto di sistemi di tariffe validi per la cubatura delle masse legnose dei principali soprassuoli di conifere della Sicilia: in particolare, i sistemi proposti si basano sull’elaborazione delle serie di inquadramento delle relazioni ipsodiametriche per il pino domestico, il pino d’Aleppo e il pino laricio. Per ciascuna specie e stato studiato l’andamento della distribuzione dei valori ipsodiametrici, risultato ben rappresentato da una forma funzionale di tipo semilogaritmico utilizzabile come «curva guida» delle serie di inquadramento delle relazioni ipsodiametriche. Adottando l’inclinazione stimata in base alla curva guida e adattando le singole s…
Editorial: New Forms of Media Work and Its Organizational and Institutional Conditions
2022
This thematic issue explores the widening scope of media work and the institutional and organizational conditions that support new forms of media work. The media industry has undergone significant economic, structural, and technological changes during the past few decades, including changing patterns of ownership and digitalization of media production, distribution, and consumption. Simultaneously, practices of media work are adopted also in other industries. The 10 articles in the issue not only focus on the new professional roles and responsibilities emerging in the news media industry but also study the practices of media work in organizations in other fields, such as the music industry …
The strong coupling constant: State of the art and the decade ahead
2022
This document provides a comprehensive summary of the state-of-the-art, challenges, and prospects in the experimental and theoretical study of the strong coupling $\alpha_s$. The current status of the seven methods presently used to determine $\alpha_s$ based on: (i) lattice QCD, (ii) hadronic $\tau$ decays, (iii) deep-inelastic scattering and parton distribution functions fits, (iv) electroweak boson decays, hadronic final-states in (v) e+e-, (vi) e-p, and (vii) p-p collisions, and (viii) quarkonia decays and masses, are reviewed. Novel $\alpha_s$ determinations are discussed, as well as the averaging method used to obtain the PDG world-average value at the reference Z boson mass scale, $\…
