Abstract We wonder if there is a way to make all Schur functions in representations equal. This impossible for fixed value of time variables, but can be achieved averages. It appears that the corresponding measure just Gaussian times, which are independent. The generating function number Young diagrams does not straightforwardly appear as product, reproduced non-trivial way.

The trend of rising scores on intelligence tests raises important questions about the comparability of variation within and between time periods. Descriptions of the processes that mediate selection of item responses provide meaningful psychological criteria upon which to base such comparisons. In a recent paper, Fox and Mitchum presented and tested a cognitive theory of rising scores on analog...

Zusammenfassung Gemäß der Wahrnehmung insbesondere von Hochschullehrenden verringern sich die Fähigkeiten Abiturientinnen und Abiturienten im Fach Mathematik seit Jahrzehnten beständig. Allerdings liegen bisher kaum empirische Untersuchungen zur Trendentwicklung Mathematikleistungen in gymnasialen Oberstufe vor. Um Frage nachzugehen, ob vermutete negative empirisch nachweisen lässt, wurden Hess...
