The calamitic LCs investigated were found to form monolayers which behave analogously to conventional amphiphiles such as fatty acids. The spreading of the discotic LCs produced monolayers as well, but with a behaviour different from classical amphiphiles. The areas occupied per molecule are too small to allow the contact of all hydrophilic groups with the water surface and the packing of all hydrophobic chains. Various molecular arrangements of the discotics at the water surface to fit the spreading data are discussed.}, language = {en} } @misc{BaltesDittmannKohliKliegl1986, author = {Baltes, Paul B. and Dittmann-Kohli, Freya and Kliegl, Reinhold}, title = {Reserve capacity of the elderly in aging-sensitive tests of fluid intelligence : replication and extension}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-39939}, year = {1986}, abstract = {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.}, language = {en} } @misc{BaltesKliegl1986, author = {Baltes, Paul B. and Kliegl, Reinhold}, title = {On the dynamics between growth and decline in the aging of intelligence and memory}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-41116}, year = {1986}, abstract = {Content: - Different Intellectual Abilities Age Differently - Cultural Change and Interindividual Variability in Aging - Cognitive Intervention Research on Plasticity in Old Age * Psychological Evidence * Brain-Physiological Evidence - Age Differences and Testing-the-Limits - Conclusions - Summary}, language = {en} } @misc{JacobiDittrich1986, author = {Jacobi-Dittrich, Juliane}, title = {Compulsory education for german immigrant children in the United States of America during the second half of the nineteenth century : the case of rural Wisconsin}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-47690}, year = {1986}, language = {en} } @misc{JacobiDittrich1986, author = {Jacobi-Dittrich, Juliane}, title = {The struggle for an identity}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-32369}, pages = {321 -- 345}, year = {1986}, abstract = {Contents: - Clara Mueller-Jahnke - Adelheid Popp - Marie Wegrainer}, language = {en} } @misc{KlieglSmithBaltes1986, author = {Kliegl, Reinhold and Smith, Jacqui and Baltes, Paul B.}, title = {Testing-the-limits, expertise, and memory in adulthood and old age}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-39063}, year = {1986}, abstract = {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 single-chain amphiphiles undergo dimerization to yield photoproducts with twice the molecular weight of the corresponding monomers in organized systems. The photoreaction of amphiphiles containing two cinnamic acid groups occurs via two mechanisms: The intramolecular dimerization produces bicycles, with retention of the molecular weight of the corresponding monomer. The intermolecular reaction leads to oligomeric and polymeric photoproducts.

Following an approach suggested by D. Magnusson and B. Ekehammer (1978, Journal of Research in Personality, 12, 41-48), individual correlations between self-reported behavior patterns and perceived similarity ratings across anxiety-provoking situations are obtained as measures of coherence. Unlike the Magnusson and Ekehammar study, the present measures of situation cognition and behavior are based on an idiographic sampling of anxiety-provoking situations. As a step toward concept-based measurement of situation cognition, further measures of perceived situational similarity are derived from the script, prototype, and social episodes models in social psychology and correlated with cross-situational similarity of behavioral profiles. It is demonstrated, in comparison with the findings of Magnusson and Ekehammar, that correlations between similarity ratings and behavior patterns increase substantially as a result of an idiographic sampling of situations. Moreover, it is shown that "script," "prototype," and "social episode" measures can be utilized to investigate the covariation between situation cognition and behavior, thus contributing to the clarification of the principles of cognitive representation of situational experience.}, language = {en} } @misc{LaschewskyRingsdorfSchneider1986, author = {Laschewsky, Andr{\´e} and Ringsdorf, H. and Schneider, J.}, title = {Oriented supramolecular systems-polymeric monolayers and multilayers from prepolymerized amphiphiles}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-17131}, year = {1986}, abstract = {Oriented polymeric membranes were originally prepared by polymerization or polycondensation of preoriented monomers. The introduction of hydrophilic spacer groups into the polymeric amphiphiles allowed the formation of highly ordered systems (monolayers, liposomes, multilayers) from prepolymerized amphiphiles: due to the partial decoupling of the different mobilities and orientation tendencies of the polymer chain and the amphiphilic side groups, these polymers are able to self-organize. In monolayer experiments the high order of these membranes could be demonstrated by their surface pressure area-diagrams. In addition the combination of order and mobility of these spacer groups containing polymeric amphiphiles allowed the formation of Langmuir-Blodgett-multilyers with a high layer correlation. Thus, disturbancies in highly oriented layers can be avoided normally taking place during the polymerization reaction (e.g. contractions) or oriented monomeric layers.}, language = {en} }
