Bezogen auf das Bruttoinlandsprodukt ist China eine wichtige regionale Wirtschaftsmacht, aber keine Supermacht. Doch das Wachstumspotential zehrt sich auf, auch weil die Investitionsdynamik der Unternehmen und der Bankensektor härteren Kreditrestriktionen unterworfen werden. Chinas bislang geschütztes Finanzsystem, das von der Globalisierung untergraben wird, ist die Achillesferse für das hohe Wachstum.
Mit dem Vertrag von Lissabon verbinden sich hohe Erwartungen hinsichtlich der Effektivität zukünftiger Regelungen zum auswärtigen Handeln der Union. In der Gestaltung dieser Bestimmungen unterliegen die Mitgliedstaaten konstitutionellen Dilemmata, die eine Lösung erschweren. Obwohl im Detail durchaus Verbesserungen erkennbar sind, werden insgesamt zunehmende Konflikte und mangelnde Kohärenz erwartet.
Werden im 21. Jahrhundert die Kriege um Wasser geführt? Von dieser Frage ausgehend diskutiert der Artikel das Konflikt- und Kooperationspotenzial an grenzüberschreitenden Flüssen. Welche Anreize gibt es für Kooperation und was führt zu Konflikten? Den theoretischen Überlegungen werden Erfahrungen an der Elbe sowie am Jordan gegenübergestellt.
Krise in Pakistan

A multitype Dawson-Watanabe process is conditioned, in subcritical and critical cases, on non-extinction in the remote future. On every finite time interval, its distribution is absolutely continuous with respect to the law of the unconditioned process. A martingale problem characterization is also given. Several results on the long time behavior of the conditioned mass process - the conditioned multitype Feller branching diffusion - are then proved. The general case is first considered, where the mutation matrix which models the interaction between the types, is irreducible. Several two-type models with decomposable mutation matrices are analyzed too .
Lithuania and Poland had cooperated for centuries and even created a political union. The pacts had been very useful for both sides and consequently, the peoples and especially the Lithuanian elite was ready to absorb parts of the Polish culture. Lithuania broke with this tradition dating back to the Middle Ages only after the first division of Poland. During 1944- 1990, the so-called "Soviet period in Lithuania", two different processes could be observed: Russification and Lithuanification. Although dependent on Moscow, the leading Lithuanian politicians never forgot Lithuanian interests and supported the national conscience. After Lithuania gained independence in 1990, a huge wave of national enthusiasm swapped over the country. In the meantime, politicians came back to reality: The independence of Lithuania seems consolidated and the old tradition to re-establish the Polish-Lithuanian cooperation seems to be on the run since Aleksander Kwasniewski had visited Lithuania in January 1996.
The authors used the frameworks of reciprocal determinism and occupational socialization to study the effects of work characteristics (consisting of control and complexity of work) on personal initiative (PI)--mediated by control orientation (a 2nd-order factor consisting of control aspiration, perceived opportunity for control, and self-efficacy) and the reciprocal effects of PI on changes in work characteristics. They applied structural equation modeling to a longitudinal study with 4 measurement waves (N = 268) in a transitional economy: East Germany. Results confirm the model plus 1 additional, nonhypothesized effect. Work characteristics had a synchronous effect on PI via control orientation (full mediation). There were also effects of control orientation and of PI on later changes in work characteristics: As predicted, PI functioned as partial mediator, changing work characteristics in the long term (reciprocal effect); unexpectedly, there was a 2nd reciprocal effect of an additional lagged partial mediation of control orientation on later work characteristics.
This article investigates the fictional narratives written by „Sub-commandante Marcos“ of the Zapatista movement EZLN. It is shown that Marcos uses three distinct frames of reference in his fictional account of the Zapatista guerrilla: an ethnic, a national and a post-national one. Contrary to other studies that emphasize the harmony between the three levels, it can be argued that there exists a fundamental tension between them. There is a tension between the ethnic discourse and the Mexican nationalist discourse which envisions a nation rather than a nation dominated by a single ethno-cultural group. Finally, it can be deduced from these tensions that the EZLN guerrilla is subject to divergent pressures.
It has recently been demonstrated that the presentation of a rare target in a visual oddball paradigm induces a prolonged inhibition of microsaccades. In the field of electrophysiology, the amplitude of the P300 component in event-related potentials (ERP) has been shown to be sensitive to the stimulus category (target vs. non target) of the eliciting stimulus, its overall probability, and the preceding stimulus sequence. In the present study we further specify the functional underpinnings of the prolonged microsaccadic inhibition in the visual oddball task, showing that the stimulus category, the frequency of a stimulus and the preceding stimulus sequence influence microsaccade rate. Furthermore, by co-recording ERPs and eye-movements, we were able to demonstrate that, despite being largely sensitive to the same experimental manipulation, the amplitude of P300 and the microsaccadic inhibition predict each other very weakly, and thus constitute two independent measures of the brain’s response to rare targets in the visual oddball paradigm.

Previous hydrometric studies demonstrated the prevalence of overland flow as a hydrological pathway in the tropical rain forest catchment of South Creek, northeast Queensland. The purpose of this study was to consider this information in a mixing analysis with the aim of identifying sources of, and of estimating their contribution to, storm flow during two events in February 1993. K and acid-neutralizing capacity (ANC) were used as tracers because they provided the best separation of the potential sources, saturation overland flow, soil water from depths of 0.3, 0.6, and 1.2 m, and hillslope groundwater in a two-dimensional mixing plot. It was necessary to distinguish between saturation overland flow, generated at the soil surface and following unchanneled pathways, and overland flow in incised pathways. This latter type of overland flow was a mixture of saturation overland flow (event water) with high concentrations of K and a low ANC, soil water (preevent water) with low concentrations of K and a low ANC, and groundwater (preevent water) with low concentrations of K and a high ANC. The same sources explained the streamwater chemistry during the two events with strongly differing rainfall and antecedent moisture conditions. The contribution of saturation overland flow dominated the storm flow during the first, high-intensity, 178-mm event, while the contribution of soil water reached 50% during peak flow of the second, low-intensity, 44-mm event 5 days later. This latter result is remarkably similar to soil water contributions to storm flow in mountainous forested catchments of the southeastern United States. In terms of event and preevent water the storm flow hydrograph of the high-intensity event is dominated by event water and that of the low-intensity event by preevent water. This study highlights the problems of applying mixing analyses to overland flow-dominated catchments and soil environments with a poorly developed vertical chemical zonation and emphasizes the need for independent hydrometric information for a complete characterization of watershed hydrology and chemistry.
The requirements of modern e-learning techniques change. Aspects such as community interaction, flexibility, pervasive learning and increasing mobility in communication habits become more important. To meet these challenges e-learning platforms must provide support on mobile learning. Most approaches try to adopt centralised and static e-learning mechanisms to mobile devices. However, often technically it is not possible for all kinds of devices to be connected to a central server. Therefore we introduce an application of a mobile e-learning network which operates totally decentralised with the help of an underlying ad hoc network architecture. Furthermore the concept of ad hoc messaging network (AMNET) is used as basis system architecture for our approach to implement a platform for pervasive mobile e-learning.
Monolayers of rod-shaped and disc-shaped liquid crystalline compounds at the air-water interface
(1986)
Calamitic (rod-shaped) and discotic (disc-shaped) thermotropic liquid crystalline (LC) compounds were spread at the air-water interface, and their ability to form monolayers was studied. 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.
Since 1989 the German-Czech relationship has been burdened by the problem of a just assessment of World War II and the following forced transfer of the Sudeten Germans. Why are democrats on both sides who acknowledge the same values and principles unable to reach an agreement about crucial events in the past? The political and legal differences imply a moral dissent which is not being discussed systematically. The article tries to investigate the deficits of the moral arguments on both sides.
Ghana’s local government system has been subject to various reform attempts which all involved some sort of decentralisation. This article tries to link decentralisation to changing national policy frames and the various governments’ need to maintain political control. Consequently, decentralisation becomes a dependent variable of the so called bureaucratic development state. After a brief discussion of the colonial and post-colonial local government system in Ghana, emphasis is placed on the crisis of the post colonial state and the emergence of a new local government system in 1988 - which was successfully transformed into the administrative system of Ghana’s 4th republic after 1992. Local participation has been substantially improved an sustained by the introduction of the District Assemblies Common Fund in 1993 which transfers 5% of the national tax income to the districts.
Neue Akzente statt Neubeginn

Two examples of our biophotonic research utilizing nanoparticles are presented, namely laser-based fluoroimmuno analysis and in-vivo optical oxygen monitoring. Results of the work include significantly enhanced sensitivity of a homogeneous fluorescence immunoassay and markedly improved spatial resolution of oxygen gradients in root nodules of a legume species.
This introduction provides an overview of feminist approaches to International Relations. The authors compare the Anglo-American debate with the Germanspeaking discussion in order to reveal similarities and differences. They identify three particular areas of research that characterize the German-speaking feminist debate in International Relations: (1) works evolving out of peace studies; (2) research on globalization and international economic institutions; (3) studies focusing on women’s movements together with most current works centering around international norms. They argue that feminist approaches to norms constitute a particularly promising research area which provides new "tools" to account for international, regional or domestic policy-change. Gender-sensitive research on norms also allows to address ethical questions that are vital for feminist understandings of science. Moreover, this new focus on norms enables bridge-building between feminism and the mainstream.
The authors analyse different Gibbsian properties of interactive Brownian diffusions X indexed by the d-dimensional lattice. In the first part of the paper, these processes are characterized as Gibbs states on path spaces. In the second part of the paper, they study the Gibbsian character on R^{Z^d} of the law at time t of the infinite-dimensional diffusion X(t), when the initial law is Gibbsian.
