Interplay of superexchange and orbital degeneracy in Cr-doped LaMnO3
We report on structural, magnetic and Electron Spin Resonance (ESR)
investigations in the manganite system LaMn_{1-x}Cr_{x}O_{3} (x<=0.5). Upon
Cr-doping we observe a reduction of the Jahn-Teller distortion yielding less
distorted orthorhombic structures. A transition from the Jahn-Teller distorted
O' to the pseudocubic O phase occurs between 0.3<x<0.4. A clear connection
between this transition and the doping dependence of the magnetic and ESR
properties has been observed. The effective moments determined by ESR seem
reduced with respect to the spin-only value of both Mn^{3+} and Cr^{3+} ions
On the nature of verb–noun dissociations in bilectal SLI: a psycholinguistic perspective from Greek
We report on object and action picture-naming accuracy in two groups of bilectal speakers in Cyprus, children with typical
language development (TLD) and children with specific language impairment (SLI). Object names were overall better
retrieved than action names by both groups. Given that comprehension for action names was relatively intact for all children,
this finding is taken to be the result of a breakdown at the interface of the semantic lexicon and phonological representations,
or access to them. The results complement similar research on English, a minimally inflected language in contrast to Greek.
Overall, cross-linguistic word class effects provide strong evidence for the hypothesis that grammatical category is an
organizing principle shared across languages. Finally, our results suggest that bilectal children with SLI present with general
lexical delay rather than a deficit in verb naming per se
