Association between phenotypic familial hypercholesterolaemia and telomere length in US adults: results from a multi-ethnic survey

2018

Aims: Familial hypercholesterolaemia (FH) accelerates atherosclerotic cardiovascular disease (ASCVD) and accordingly is the most potent hereditary cause of premature coronary heart disease. The association between telomere length (TL), a biological index of ageing, and FH has not been hitherto investigated. We addressed this question using data from the US National Health and Education National Surveys (NHANES, 1999-2002).Methods and results: We included individuals, who had TL measurements (with quantitative polymerase chain reaction method) and a phenotypic diagnosis of FH based on the Dutch Lipid Clinic Network (DLCN) criteria. Sample weights were applied for unequal probabilities of sel…

Abstract In an ever-evolving technological landscape that challenges teaching professionals' digital competence, this study complements previous studies by providing an overall picture of teaching professionals' digital competence. We employed regression models on two large-scale assessment data sets on teachers from 11 countries—namely, the Teaching and Learning International Survey (TALIS; n = 50,800) and the Programme for the International Assessment of Adult Competencies (PIAAC; n = 2590)—to investigate through the theoretical lens of digital competence how teaching professionals' skills, attitudes and knowledge distribute and relate, and how they are associated with personal and contex…

Quelques réflexions méthodologiques à propos des enquêtes internationales dans le domaine de l'éducation

2004

This article aims to show by means of three examples taken from the analysis of the results of the OECD Programme de Suivi des Acquis des Elèves (PISA 2000) the impact of certain methodological choices on the results obtained. More precisely, we shall deal with the consequences of i) the form of the answers (open or closed) on the boys' and girls' success rates, ii) the definition of the targeted populations (one given year of study vs the pupils of a given age) on the differences observed between the educational institutions and iii) the way of defining the concept of "immigrant" on the resultts of pupils who were born of not born in the country where they were tested.

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.

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.

De l'école unifiée aux écoles plurielles. Évaluation internationale des politiques de différenciation et de diversification de l'offre éducative

2004

The last two decades have been marked in many developed and emerging countries by major educational reforms, around special themes: decentralization, the differentiation of courses and school content and the free choice of school. These three education policies, which aim to differentiate and diversify the educational offer, call into question the traditional organization of modern educational systems. This study seeks to evaluate the effects of these reforms on the performance of education systems, thanks to an econometric analysis based, on the one hand, on the results of the PISA 2000 international evaluation and, on the other, on a a fine description of the institutional characteristics…

Imaging of hepatocellular carcinoma: a pilot international survey
