T1 - Binding and degradation of juvenile hormone III by haemolymph proteins of the Colorado potato beetle: a re-examination N2 - The haemolymph of the adult Colorado potato beetle, Lepinotarsa decemlineata Say, contains a high molecular weight (MW > 200,000) JH-III specific binding protein. The Kd value of the protein for racemic JH-III is 1.3 ± 0.2 × 10−7 M. It has a lower affinity for racemic JH-I and it does not bind JH-III-diol or JH-III-acid. The binding protein does discriminate between the enantiomers of synthetic, racemic JH-III as was determined by stereochemical anaysis of the bound and the free JH-III. Incubation of racemic JH-III with crude haemolymph results in preferential formation of (10S)-JH-III-acid, the unnatural configuration. The JH-esterase present in L. decemlineata haemolymph is not enantioselective. It is concluded that the most important function of the binding protein is that of a specific carrier, protecting the natural hormone against degradation by esterases. The carrier does not protect JH-I as efficiently as the lower homologue.

Für den Bildungspraktiker ergeben sich Gründe vor allem aus der wiederholten Erfahrung von Diskrepanzen. Erstens die Diskrepanzen, die zwischen der Definition von Lehrzielen und ihrem Erreichen in der Erwachsenenbildung bestehen. Zweitens die Diskrepanzen, die zwischen dem tatsächlich erlernten Wissen und seiner Umsetzung und Anwendung in der Praxis sich auftun.

Fujimori was one of the more autocratic Latin American leaders of the 1990s, he is being the only regime formally to break with pre-existing constitutional rules. Closely tied to the military and intelligence apparatus, his government involved a concentration of political power that reduced the scope and autonomy of other branches of the state. But, unlike previous Latin American military dictatorships, Fujimori’s government enjoyed a considerable popularity, born out of disaffection for representative institutions. The article argues, however, that these characteristics of apparent strength carried within them the seeds of their own destruction. Far from establishing lasting political stability, the regime was weakly based. Within six weeks of his inauguration for a third term in July 2000, Fujimori was obliged to announce his intention to withdraw from politics. Two months later, he was ousted altogether.

Whereas legal and constitutional theory take more and more bold views concerning integrating structures of checks and balances and division of powers into the legal system, urging for statutory control of the ruling party, for reforming the National People’s Congress into a responsible legislative body based on real representation of the people, providing for constitutionality of legal norms by a system of judicial review etc., legislation has started to deal with certain aspects of the Rechtsstaat in fields as administrative, criminal and criminal procedure law. In view of grave problems of implementation, this legislation may partly be regarded more to be an expression of intention to develop gradually a new ideal and a new legitimation for the political system than well established actual practice.

The interaction is supposed to be small in the norm ||.||∞ but otherwise is very general, being possibly non-regular and non-Markovian. Our method consists in using the characterization of such diffusions as space-time Gibbs fields so that we construct them by space-time cluster expansions in the small coupling parameter.

N2 - The "Forum" of WeltTrends No. 32 assembles sixteen analyses of the aftermath of the September 2001 terrorist attacks on the United States, written by distinguished scholars from Germany, Britain, France, the U.S., the Czech Republic, Russia and China. The contributions deal with topics such as international and domestic security, the social and political causes of terrorism, international law, asylum policy, the classification of the attacks as crimes or acts of war, implications for international bodies such as NATO and the UN, and the effect of the attacks on the relationship between the U.S., Europe, Russia, and Asia, in particular Japan and China. The authors counsel strongly against scare mongering and short-term symbolic politics. Any attempt to deal with the complex problem of terrorism has to include long-term political and social policies aimed at the reduction of conflict and sources of political extremism in the Middle Eastern region. There is no reason for panic according to the authors but international politics after September 11th cannot go on like before.

A1 - Kliegl, Reinhold T1 - Aging and human macular pigment density : appended with translations from the work of Max Schultze and Ewald Hering N2 - The optical density of human macular pigment was measured for 50 observers ranging in age from 10 to 90 years. The psychophysical method required adjusting the radiance of a 1°, monochromatic light (400–550 nm) to minimize flicker (15 Hz) when presented in counterphase with a 460 nm standard. This test stimulus was presented superimposed on a broad-band, short-wave background. Macular pigment density was determined by comparing sensitivity under these conditions for the fovea, where macular pigment is maximal, and 5° temporally. This difference spectrum, measured for 12 observers, matched Wyszecki and Stiles's standard density spectrum for macular pigment. To study variation in macular pigment density for a larger group of observers, measurements were made at only selected spectral points (460, 500 and 550 nm). The mean optical density at 460 nm for the complete sample of 50 subjects was 0.39. Substantial individual differences in density were found (ca. 0.10–0.80), but this variation was not systematically related to age.

Akan has two types of wh-question structures (wh-in-situ and wh-ex-situ questions), which allows an investigation of children’s acquisition of these two question structures and their preferences for one or the other. Our results show that adults prefer to use wh-ex-situ questions over wh-in-situ questions. The results from the children show that both age groups have the two question structures in their linguistic repertoire. However, they differ in their preferences in usage in the elicited production task: while the 5-year-olds preferred the wh-in-situ structure over the wh-ex-situ structure, the 4-year-olds showed a selective preference for the wh-in-situ structure in who-questions. These findings suggest a developmental change in wh-question preferences in Akan-learning children between 4 and 5 years of age with a so far unobserved u-shaped developmental pattern. In the elicited imitation task, all groups showed a strong tendency to maintain the structure of in-situ and ex-situ questions in repeating grammatical questions. When repairing ungrammatical ex-situ questions, structural changes to grammatical in-situ questions were hardly observed but the insertion of missing morphemes while keeping the ex-situ structure. Together, our findings provide only partial support for the Derivational Complexity Hypothesis.
