Carbohydrate quality changes and concurrent changes in cardiovascular risk factors: a longitudinal analysis in the PREDIMED-Plus randomized trial.
2020
[Background]: Overall quality of dietary carbohydrate intake rather than total carbohydrate intake may determine the risk of cardiovascular disease (CVD).
Reliability and validity evidence of the early numeracy test for identifying children at risk for mathematical learning difficulties
2020
Abstract This study investigated reliability and validity evidence regarding the Early Numeracy test (EN-test) in a sample of 1139 Swedish-speaking children (587 girls) in kindergarten (n = 361), first grade (n = 321), and second grade (n = 457). Structural validity evidence was established through confirmatory factor analysis (CFA), which showed that a four-factor model fit the data significantly better than a one-factor or two-factor model. The known-group and cross-cultural validity were established through multigroup CFAs, finding that the four-factor model fit the gender, age and language groups equally well. Internal consistency for the test and sub-skills varied from good to excellen…
Longitudinal Relationships Between Job Satisfaction and Creative Performance: A Three-Wave Cross-Lagged Panel Design
2020
Despite the assumption about the positive relationship between wellbeing and performance within the happy and productive worker thesis (HPWT), the matter is still under discussion due to inconclusive results. To better understand the link between wellbeing and performance and delineate their possible causal relationships, it is necessary to conduct longitudinal studies with data collection at different moments, as well as broaden the focus by considering different types of wellbeing and performance. To achieve this, the authors of this study analyzed the relationship between intrinsic (IJS) and extrinsic job satisfaction (EJS) with creative performance. The design consisted of a three-time …
Trends of organochlorine compounds in Finnish inland waters
2001
Caged common lake mussels (Anodonta piscinalis) have been used in the monitoring of organochlorine compounds in pulp and paper mill recipient watercourses of Finland annually from 1984 to 1998. Statistically significant decreasing trends of chlorophenols and chloroguaiacols originating from chlorobleaching were observed in all recipients in parallel with the decreasing discharges from the mills. Metabolites of chlorophenols, chloroanisoles and chloroveratroles had no or slightly increasing trends. Elevated PCB concentrations were measured in four watercourses. In two areas, PCBs were found to be significantly increasing, in two other cases they showed no trend. A mill producing recycled pap…

Les parcours d'insertion des jeunes
2011
Cet article présente une méthode pour élaborer des typologies d'itinéraires individuels qui prenne en compte la dynamique longitudinale des parcours. Elle s'applique lorsque ces itinéraires sont décrits à partir de calendriers. L'originalité de cette méthode réside à la fois dans le mode de calcul de la distance entre trajectoires, et dans la procédure de classification basée sur les cartes d'auto-organisation de Kohonen. La propriété principale de la distance est de prendre en compte de la proximité entre les états et son évolution dans le temps. Cette méthode est appliquée ici à l'analyse des trajectoires professionnelles, à partir de données du Céreq permettant le suivi mensuel sur sept …
Changes in children's sleep domains between 2 and 3 years of age: the Ulm SPATZ Health Study
2017
Abstract Objective There is growing interest in the link between sleep habits and child health but reference values specific to toddlers as well as longitudinal data on sleep are scarce. We aimed to describe parent-reported child sleep habits and their intra-individual changes in 2- to 3-year-olds using data from a regional birth cohort study. Methods In the Ulm SPATZ Health Study, a birth cohort study conducted at Ulm, Southern Germany, with baseline examination from April 2012 to May 2013, the German version of the Children's Sleep Habits Questionnaire (CSHQ-DE) was used longitudinally at follow-ups at 2 and 3 years ( N = 615 children). Descriptive statistics including intra-individual di…
Parents' causal attributions concerning their children's academic achievement
2007
Katja Natale seurasi väitöstutkimuksessaan vanhempien lastensa koulumenestystä koskevien kausaaliattribuutioiden eli syyselitysten muotoutumista lasten siirtyessä esikoulusta kouluun. Hän tutki kuinka tärkeinä vanhemmat pitivät kykyä, yrityksen määrää, tehtävien vaikeustasoa ja lapsen saamaa ohjausta selittämässä lasten onnistumista ja epäonnistumista koulussa. - Koulunsa aloittavien lasten vanhempia voisi neuvoa viestimään lapsilleen, että heillä on kykyjä onnistua haastavissakin koulutehtävissä. Tällainen viesti vaikuttaa positiivisesti lasten koulutaitojen kehitykseen ja minäkuvan muuttumiseen realistisemmaksi, Natale suosittaa.Onnistuminen kyvykkyyttä, epäonnistuminen yrityksen puutetta…
Gender Inequalities and Social Sustainability. Can Modernization Diminish the Gender Gap in Political Knowledge?
2020
The gender gap in political knowledge is a classical problem of Western democracies. In the 21st century, political knowledge is still unequally distributed between men and women, as many cross-section studies have shown. This is an indicator of women’s disempowerment and the distance which remains to be covered to achieve an inclusive and sustainable society. Could public policies and gender equality laws change the situation? Using a longitudinal database in which 600,000 survey responses are analysed from 1996 to 2017, this case study of Spain aims to shed some light on this question. It combines sociological and political approaches in line with the development theory of the gender gap …
Rosenbluth Separation of the π^{0} Electroproduction Cross Section.
2016
We present deeply virtual $\pi^0$ electroproduction cross-section measurements at $x_B$=0.36 and three different $Q^2$--values ranging from 1.5 to 2 GeV$^2$, obtained from experiment E07-007 that ran in the Hall A at Jefferson Lab. The Rosenbluth technique was used to separate the longitudinal and transverse responses. Results demonstrate that the cross section is dominated by its transverse component, and thus is far from the asymptotic limit predicted by perturbative Quantum Chromodynamics. An indication of a non-zero longitudinal contribution is provided by the interference term $\sigma_{LT}$ also measured. Results are compared with several models based on the leading twist approach of G…
