Die Wirkung der Variablen ‚Intelligenz‘ und ‚Geräuschintensität‘ auf die unmittelbare Lernleistung wurde mit zwei Tests untersucht. Dadurch sollten die „Stimulus trace"-Theorie (Ellis 1963) und die „neural theory" (Spitz 1963) bei 45 deutschen, lernbehinderten Kindern geprüft werden. Der „Stimulus trace"-Faktor ließ sich für Geräuschreize nicht bestätigen. Es gab keinen Beweis für die Gültigkeit der neuralen Theorie. Bei Erhöhung der Lautstärke sank die Lernleistung in beiden Tests.
The synthesis of galactose clusters that are linked to a steroid moiety by a peptide-like spacer unit is described. The galactose cluster is obtained by Koenigs-Knorr glycosylation of TRIS-Gly-Fmoc (2b) under Helferich conditions. Peptide and ester bonds are formed after activation of carboxylic acids as diphenylthiophene dioxide (TDO) esters. 6a is synthesized in a convergent way by coupling of (Ac4Gal)3-TRIS-Gly (3e) with cholesteryl TDO succinate (5b). Coupling of (Ac4Gal)3-TRIS-Gly hydrogen succinate (3f) with Gly-O-Chol (5d) by means of EEDQ yields 6d. Reaction of (Ac4Gal)3-TRIS-Gly-SUCC-O-TDO (3g) with 25-hydroxycholesterol leads in a linear sequence to the oxysterol derivative 6f. Selective cleavage of the acetyl groups from galactose units yields the known compound 6b and the new derivatives 6e and 6g.
In the earliest recorded poetry of the Insular Celtic literature, the occurrence intra-linear phoneme recurrences in addition to the rather common feature of alliteration suggest that they served an indexical motivation of the metrical constraints. This is in particular suggested by the indexical use of personal names. This practice may perhaps even reach back to Continental Celtic metrical practices which already seem to bear witness of the use of such language skills. It is particularly interesting to note that the initial mutations of the lexemes do not obstruct indexicality. It is suggested that the orally trained poets may perhaps have received specific grammatical instructions as part of their prolongued poetic education.
realisation in form of a retroflex is not only found in the English south West ('West Country burr'), but also across the English Channel in a well circumscribed area of Trégor in Brittany. Both areas also share other phonetic features such as sonorisation of word initial fricatives, epenthesis, surnames etc. How is this to be explained? Intensive mobility and trade across the sea suggest themselves as a possible answer. Travelling by sea, aided by expert knowledge of the seasonal currents and winds, was much quicker and efficient in former times than travelling across land. In this connection, the phenomenon of the "Johnnys de Roccoff" who traded Breton onions along the English coasts until very recently is pointed ou as a type of contact which may have transported phoneme realisations and lexis across the sea, forming a linguistic area with not much contact with their respective hinterlands in England and Brittany.
