EF sind bereichs{\"u}bergreifende Pr{\"a}diktoren schulischer Leistungen. Verschiedene Operationalisierungen derselben Komponente, z.B. Performanztests und Elterneinsch{\"a}tzungen, zeigen h{\"a}ufig nur geringe Interkorrelationen. Die Methoden scheinen unterschiedliche Aspekte einer Komponente zu erfassen, daher k{\"o}nnte eine Kombination zur Vorhersage schulischer Leistungen sinnvoll sein. Methode: N = 96 Erst- und Zweitkl{\"a}ssler_innen mit und ohne Entwicklungsauff{\"a}lligkeiten wurden mittels EF-Performanztests und Schulleistungstests zu Mathematik und Lesen untersucht. Per Fragebogen wurden elternbeurteilte EF und als Kontrollvariablen der sozio{\"o}konomische Status (S{\"O}S) und das Vorliegen von Merkmalen einer Aufmerksamkeitsdefizit-Hyperaktivit{\"a}tsst{\"o}rung (ADHS) erfasst. Ergebnisse: Elternbeurteilungen hatten {\"u}ber die Performanztests hinaus einen bedeutsamen Vorhersagewert f{\"u}r die Mathematik- und Leseleistung. Der Einfluss von Alter, S{\"O}S und ADHS-Merkmalen wurde kontrolliert. Diskussion: Die kombinierte Anwendung beider Erfassungsmethoden scheint somit vorteilhaft f{\"u}r die Prognose schulischer Leistungen und die Pr{\"a}vention von Schulleistungsproblemen.}, language = {de} } @article{KalousekMitraSchloemerkemper2021, author = {Kalousek, Martin and Mitra, Sourav and Schl{\"o}merkemper, Anja}, title = {Existence of weak solutions of diffuse interface models for magnetic fluids}, series = {Proceedings in Applied Mathematics and Mechanics}, volume = {21}, journal = {Proceedings in Applied Mathematics and Mechanics}, number = {1}, doi = {10.1002/pamm.202100205}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-257642}, year = {2021}, abstract = {In this article we collect some recent results on the global existence of weak solutions for diffuse interface models involving incompressible magnetic fluids.

Although heritability estimates suggest a genetic contribution, no previous study has conclusively identified a genetic risk variant for mathematical performance. Research has shown that the prevalence of mathematical disabilities is increased in children with dyslexia. We therefore correlated genome-wide data of 200 German children with spelling disability, with available quantitative data on mathematic ability. Replication of the top findings in additional dyslexia samples revealed that rs133885 was a genome-wide significant marker for mathematical abilities\((P_{comb}=7.71 x 10^{-10}, n=699)\), with an effect size of 4.87\%. This association was also found in a sample from the general population (P=0.048, n=1080), albeit with a lower effect size. The identified variant encodes an amino-acid substitution in MYO18B, a protein with as yet unknown functions in the brain. As areas of the parietal cortex, in particular the intraparietal sulcus (IPS), are involved in numerical processing in humans, we investigated whether rs133885 was associated with IPS morphology using structural magnetic resonance imaging data from 79 neuropsychiatrically healthy adults. Carriers of the MYO18B risk-genotype displayed a significantly lower depth of the right IPS. This validates the identified association between rs133885 and mathematical disability at the level of a specific intermediate phenotype.}, language = {en} }
