OR-039 Normal-weight obesity and physical fitness in Chinese university students: an overlooked association
2018
Objective The primary aim of this study was to examine the associations of normal weight obesity with physical fitness in Chinese university students. As a secondary aim, we assessed whether possible differences in physical fitness between students classified as NWO and normal weight non-obese (NWNO) were mediated by skeletal muscles mass.
 Methods A total of 383 students (205 males and 178 females, aged 18–24 years) from two universities volunteered to participate in this study. Body height and weight were measured by standard procedures and body composition was assessed by a bio-impedance device (InBody 720). NWO was defined by a BMI of 18.5 - 23.9 kg/m2 and a body fat percentage of …
Employment Effects of Skills Around the World: Evidence from PIAAC
2017
Making use of an international survey that directly assesses participants’ cognitive skills, I study the effect of skills on workers’ employment in 32 countries. On average, a one-standard-deviation increase in numeracy skills is associated with a 7.6 percentage points increase in the probability of being employed. Controlling for years spent in education, the employment effect of numeracy skills falls to 4.8 percentage points. Numeracy skills account for 30 percent of the 2.7 percentage points employment effect that is associated with years of education. There is considerable heterogeneity across both subgroups and countries.
Seaweed fails to prevent ocean acidification impact on foraminifera along a shallow-water CO2 gradient
2015
Ocean acidification causes biodiversity loss, alters ecosystems, and may impact food security, as shells of small organisms dissolve easily in corrosive waters. There is a suggestion that photosynthetic organisms could mitigate ocean acidification on a local scale, through seagrass protection or seaweed cultivation, as net ecosystem organic production raises the saturation state of calcium carbonate making seawater less corrosive. Here, we used a natural gradient in calcium carbonate saturation, caused by shallow-water CO2 seeps in the Mediterranean Sea, to assess whether seaweed that is resistant to acidification (Padina pavonica) could prevent adverse effects of acidification on epiphytic…
Seawater carbonate chemistry and growth, physiological performance of the Manila clam Ruditapes philippinarum
2018
Ocean acidification may interfere with the calcifying physiology of marine bivalves. Therefore, understanding their capacity for acclimation and adaption to low pH over multiple generations is crucial to make predictions about the fate of this economically and ecologically important fauna in an acidifying ocean. Transgenerational exposure to an acidification scenario projected by the end of the century (i.e., pH 7.7) has been shown to confer resilience to juvenile offspring of the Manila clam, Ruditapes philippinarum. However, whether, and to what extent, this resilience can persist into adulthood are unknown and the mechanisms driving transgenerational acclimation remain poorly understood.…
Seawater carbonate chemistry and carbon sources of mussel shell carbonate
2018
Ocean acidification and warming is widely reported to affect the ability of marine bivalves to calcify, but little is known about the underlying mechanisms. In particular, the response of their calcifying fluid carbonate chemistry to changing seawater carbonate chemistry remains poorly understood. The present study deciphers sources of the dissolved inorganic carbon (DIC) in the calcifying fluid of the blue mussel (Mytilus edulis) reared at two pH (8.1 and 7.7) and temperature (16 and 22 °C) levels for five weeks. Stable carbon isotopic ratios of seawater DIC, mussel soft tissues and shells were measured to determine the relative contribution of seawater DIC and metabolically generated carb…
Employment effects of skills around the world: Evidence from the PIAAC
2020
Using an international survey that directly assesses the cognitive skills of participants, the author studies the effect of skills on employment in 32 countries. On average, a 1 standard deviation increase in numeracy is associated with an 8.4 percentage point increase in the probability of being employed, reducing the probability of being out of the labour force and unemployed by 6.4 and 2.1 percentage points, respectively. After controlling for numeracy, the estimated employment effect of years in education falls by one third, from 2.7 to 1.8 percentage points. Notably, the employment effect of skills is more pronounced in countries with higher unemployment.
Notional defined contribution pension schemes: Why does only Sweden distribute the survivor dividend?
2015
The aim of this paper is to analyse the role of the survivor dividend in notional defined contribution (NDC) pension schemes. At present, this feature can only be found in the Swedish defined contribution scheme. We develop a model that endorses the idea that the survivor dividend has a strong basis for enabling the NDC scheme to achieve financial equilibrium and that not including the dividend is a non-transparent way of compensating for increases in longevity and/or legacy costs from old pension systems. We also find that the average effect of the dividend remains unchanged for any constant annual rate of population growth, that contribu-tors who reach retirement age always get a higher r…
Test-retest reliability data of functional performance, strength, peak torque and body composition assessments in two different age groups of Kosovan…
2021
This article reports test-retest reliability data of laboratory- and field-based performance tests as well as body composition analyses of younger and older Kosovan adults. In total, 57 healthy young (18–35 years) and 61 older (>60 years) participants took part in two identical test sessions, with a median [25th – 75th percentile] of 14 [13–21] days in between. Functional performance tests included 30-s chair stand test (CST), 30-s arm curl test (ACT), six-minutes walking test (6MWT), sit and reach test, timed up and go test (TUG), as well as the assessment of gait speed (GS) at normal and fast pace. Isometric handgrip strength (HGS) was used to estimate strength of the dominant hand. Isoki…
<p>Circulating Irisin Levels as a Marker of Osteosarcopenic-Obesity in Cushing’s Disease</p>
2020
Purpose To evaluate circulating irisin levels in patients with active and controlled Cushing's disease (CD). Design Forty-four patients with CD evaluated during the active phase and after 12 months of biochemical remission and 40 controls were recruited. Methods Phenotypic, anthropometric, hormonal and metabolic parameters, including insulin sensitivity estimation by homeostatic model of insulin resistance, Matsuda index and oral disposition index and circulating irisin levels were evaluated. Results Patients with active CD showed lower irisin levels compared to controls (p<0.001) and controlled CD (p<0.001). The independent variables significantly associated with irisin were waist circumf…
A Monte Carlo-based dosimetric characterization of Esteya® , an electronic surface brachytherapy unit
2018
PURPOSE The purpose of this work is threefold: First, to obtain the phase space of an electronic brachytherapy (eBT) system designed for surface skin treatments. Second, to explore the use of some efficiency enhancing (EFEN) strategies in the determination of the phase space. Third, to use the phase space previously obtained to perform a dosimetric characterization of the Esteya eBT system. METHODS The Monte Carlo study of the 69.5 kVp x-ray beam of the Esteya® unit (Elekta Brachytherapy, Veenendaal, The Netherlands) was performed with PENELOPE2014. The EFEN strategies included the use of variance reduction techniques and mixed Class II simulations, where transport parameters were fine-tune…
