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…
Impurity analysis of JET DiMPle pulses
2021
Divertor monitoring pulses (DiMPle) have been run in JET from the C35 campaign onwards. They provide an opportunity to study the impurity contamination of the plasma when it is limited by different surfaces within the machine, as well as the longer term behaviour of the impurities. In these discharges the plasma is first limited on the outer wall, then on the inner wall and, subsequently, in the X-point configuration the outer strike point is positioned on the horizontal tile 5 of the machine followed by tile 6 and then the vertical tile 7. The present study details the impurity behaviour in the DiMPle pulses from JET-ILW campaigns C35 to C38, which ran from 2015 to 2019. The impurities can…

The phylogeny of (Gentianaceae) and its colonization of the southern hemisphere as revealed by nuclear and chloroplast DNA sequence variation
2001
Abstract The generic circumscription and infrageneric phylogeny of Gentianella was analysed based on matK and ITS sequence variation. Our results suggested that Gentianella is polyphyletic and should be limited to species with only one nectary per petal lobe. Gentianella in such a circumscription is most closely related to one part of a highly polyphyletic Swertia. within uninectariate Gentianella two major groups could be recognized: 1) northern hemispheric species with vascularized fimbriae at the base of the corolla lobes, and 2) northern hemispheric, South American, and Austrlia/New Zealand species without vascularized fimbriae. When fimbriae are present in this latter group, they are n…

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 …
Constraining the nonstandard interaction parameters in long baseline neutrino experiments
2016
In this article we investigate the prospects for probing the strength of the possible non-standard neutrino interactions (NSI) in long baseline neutrino oscillation experiments. We find that these experiments are sensitive to NSI couplings down to the level of 0.01-0.1 depending on the oscillation channel and the baseline length, as well as on the detector's fiducial mass. We also investigate the interference of the leptonic CP angle $\delta_{CP}$ with the constraining of the NSI couplings. It is found that the interference is strong in the case of the $\nu_{e}\leftrightarrow\nu_{\mu}$ and $\nu_{e}\leftrightarrow\nu_{\tau}$ transitions but not significant in other transitions. In our numeri…
