Der hier berichtete Forschungsansatz kombiniert entwicklungs- und kognitionspsychologische Fragestellungen. Das entwicklungspsychologische Ziel war, Potential und Grenzen latenter kognitiver Leistungsreserven bei jungen und älteren Erwachsenen sichtbar zu machen. Eine systematische Heranführung an Leistungsgrenzen sollte außerdem die unterschiedliche Alterssensitivität kognitiver Prozesse verdeutlichen und zu einer Vergrößerung interindividueller Unterschiede führen. Das kognitionspsychologische Ziel war, die Genese kognitiver Expertise unter Laborbedingungen zu simulieren, wobei vor allem die Transformation von Laien- in Expertenwissen untersucht werden sollte. Diese Überlegungen wurden in einem Trainingsprogramm überprüft, in dessen Verlauf junge und ältere Erwachsene in einer Gedächtniskunst für das Behalten von Zufallszahlen und Wortlisten unterwiesen wurden. Die Brauchbarkeit dieses experimentellen Paradigmas für die Überprüfung der theoretischen Fragen wird durch Ergebnisse aus vier Einzelfallstudien belegt.
This research has three interrelated foci: (i) engineering and testing a cognitive model of expert memory, (ii) the study of intellectual reserve capacity and (iii) the use of a testing-the-limits methodology to magnify and delineate age differences in limits of reserve capacity. The assumption is that age differences are magnified if studied at high levels of expertise or task difficulty. Results from age-comparative point training studies in expert memory are reported. Both young and elderly subjects reached high levels of skilled memory, confirming the model. However, despite this sizeable reserve capacity, when compared to IQ-eguivalent young adults, superior elderly showed decline in upper limits of function.
Fluid intelligence belongs to that cluster of intellectual abilities evincing aging loss. To examine further the range of intellectual reserve available to aging individuals and the question of replicability in a new cultural and laboratory setting, 204 healthy older adults (mean age = 72 years; range = 60-86) participated in a short-term longitudinal training study. For experimental subjects, 10 sessions consisted of cognitive training involving two subability tests (Figural Relations, Induction) of fluid intelligence. The pattern of outcomes replicates and expands on earlier studies. Older adults have the reserve to evince substantial increases in levels of performance in fluid intelligence tests. Transfer of training, however, is narrow in scope. Training also increases accuracy of performance and the ability to solve more difficult test items. Difficulty level was estimated in a separate study, with a comparable sample of N = 112 elderly adults. Future research is suggested to examine whether intellectual reserve extends to near-maximum levels of performance.
This paper investigates speech styles and style-shifting in the speech of the moderator of a German radio participation programme. Style-shifting is shown to affect several distinct linguistic levels: phonetic, morphophonemic, syntactic, and lexical. The functions of style-shifting are related both to the discourse context and the broader institutional context. Relying on listeners' co-occurrence expectations with respect to language use in contexts and exploiting listeners' evaluations of processes of speech convergence and divergence, the moderator uses stereotypic markers at different style levels in locally strategic functions in discourse. On the one hand, thematic development is controlled by reinforcing obligations on the addressee. On the other hand, global social reciprocity patterns are constituted and secured. Patterns of reciprocity vary with different types of addressees. The conversational analysis of language variation shows that variation is not only a quantitative correlate of regional, social and contextual parameters as predominantly conceived of in sociolinguistics. Language variation is furthermore used as a means to signal social and interactive meaning in conversations.
Die Namen Gottes und der himmlischen Mächte : ihre Funktion und Bedeutung in der Hekhalot-Literatur
(1985)
Auszug: "Names and adjurations are the two main theurgic means found in the Hekhalot literature applied in connection with the descend to the Merkava and the invocation of angels to come down to earth and to reveal secrets" - so I. Grünwald in seinem Buch über die Merkava Literatur - er fährt sodann fort und stellt mit Gershom Scholem fest, "that that particular element in the Hekhalot literature actually belonged to its very heart and this almost from its beginning" . Diese zweifellos richtige und wichtige Feststellung verweist auf ein Element, das diese Literatur von der biblischen und rabbinischen gleichermaßen unterscheidet. Wenn dieses Charakteristikum der Namenfülle schon rein äußerliches Unterscheidungs- und Zuordnungskriterium sein kann und die Namen geradezu zur Mitte dieser Literatur gehören, liegt es nahe, vom Verständnis gerade dieses Phänomens eine tiefere Einsicht in das Wesen der Hekhalotliteratur und in das Denken ihrer 'Autoren' zu gewinnen.

Langmuir-Blodgett multilayers of polymerizable carboxylic acids with hydrocarbon or fluorocarbon chains were prepared. The multilayers were polymerized by UV light and the reactions were studied by UV/visible spectroscopy. The polyreactions strongly influence the multilayer structures which were investigated by X-ray small-angle scattering and scanning electron microscopy. The spreading behaviour of the monomers, the preparation of multilayers, their reactivities in multilayers and structural effects caused by the polyreactions are discussed with regard to the hydrophilic head groups, the polymerizable groups and the hydrophobic chains.
A variety of polymerizable lipids containing a hydrophilic spacer group between the reactive group and the main amphiphilic structure have been synthesized. They were investigated in monolayers, liposomes, and multilayers. When the spacer concept was used, efficient decoupling of the motions of the polymeric chain and the amphiphilic side groups is achieved. Thus, the often found loss of the important fluid phases by polymerization is avoided. Polymeric monolayers of the spacer lipid, prepared either by polymerization in the monolayer or by spreading of prepolymerized lipid, exhibit nearly identical surface pressure-area diagrams. Most distinctly, the successful decoupling of the motions of the polymer main chain and the membrane forming amphiphilic side groups is demonstrated by the self-organization of bulk polymerized spacer lipids to polymeric liposomes. In addition, spacer lipids are able to build polymeric Langmuir-Blodgett multilayers. The decoupling of the polymer main chain and the membrane-forming amphiphilic side groups enables the deposition of already polymeric monolayers onto supports to form defined multilayers. If, alternatively, monomeric monolayers are deposited and polymerized on the support, defects in the layers due to structural changes during the polymerization are avoided by the flexible spacer group.
Wir wollen mit der folgenden Analyse am Beispiel der Bürger-Verwaltungs-Kommunikation verdeutlichen, daß sich die Anwendung linguistischer Beschreibungsverfahren bei der Interpretation von Texten — in diesem Fall von gesprochenen Texten, die den Erfahrungsbereich der Schüler betreffen — als hilfreich erweisen kann. Sie kann dazu beitragen, in der Praxis immer wieder erlebte Kommunikationsprozesse und darin auftretende Verständigungsprobleme besser zu durchschauen und damit auf eigenes Handeln in diesen Prozessen vorzubereiten.
