We adopt the concepts of microstates and macrostates from statistical mechanics. The microstates are the detailed patterns of initial soil moisture that are inherently unknown, while the macrostates are specified by the statistical distributions of initial soil moisture that can be derived from the measurements typically available in field experiments. We use a physically based model and ensure that it closely represents the processes in the Weiherbach catchment, Germany. We then use the model to generate hydrologic response to hypothetical irrigation events and rainfall events for multiple realizations of initial soil moisture microstates that are all consistent with the same macrostate. As the measures of uncertainty at the plot scale we use the coefficient of variation and the scaled range of simulated vertical bromide transport distances between realizations. At the catchment scale we use similar statistics derived from simulated flood peak discharges. The simulations indicate that at both scales the predictability depends on the average initial soil moisture state and is at a minimum around the soil moisture value where the transition from matrix to macropore flow occurs. The predictability increases with rainfall intensity. The predictability increases with scale with maximum absolute errors of 90 and 32% at the plot scale and the catchment scale, respectively. It is argued that even if we assume perfect knowledge on the processes, the level of detail with which one can measure the initial conditions along with the nonlinearity of the system will set limits to the repeatability of experiments and limits to the predictability of models at the plot and catchment scales.

Relations between the two governments are progressing nicely. But public opinion and behaviour are still lagging behind. The author describes how thought and emotions on the Polish side are still influenced by memories of the past, especially of the German occupation during the Second World War, and the slow pace of progress in overcoming that memory. He shows that the "shadows of history" have strongly influenced Polish politics in the context of German reunification. Special emphasis is given to the role of the Catholic Church in the controversial debate on the relations towards Germany in the 1950s and 1960s.

Therefore, more effective inter- or transport layers are urgently required. To tackle these recombination losses, we introduce ortho-carborane as an interlayer material that has a spherical molecular structure and a three-dimensional aromaticity. Based on a variety of experimental techniques, we show that ortho-carborane decorated with phenylamino groups effectively passivates the perovskite surface and essentially eliminates the non-radiative recombination loss across the perovskite/C₆₀ interface with high thermal stability. We further demonstrate the potential of carborane as an electron transport material, facilitating electron extraction while blocking holes from the interface. The resulting inverted perovskite solar cells deliver a power conversion efficiency of over 23% with a low non-radiative voltage loss of 110 mV, and retain >97% of the initial efficiency after 400 h of maximum power point tracking. Overall, the designed carborane based interlayer simultaneously enables passivation, electron-transport and hole-blocking and paves the way toward more efficient and stable perovskite solar cells.

She argues that there is a set of historical and geopolitical reasons for doing so. But whilst the Polish aim is to normalise its relationship to its neighbours, the perception of Russians and Germans in Poland is rather different. On the one hand, in the Polish people opinion, Germany is the main promoter of their European institutional integration wishes. On the other, relatively aggressive attitude towards Russia can also be identified. The essay is a strong plea for mutual responsibility and co-operation in favour of peace and security in Europe. Additionally Russia is to be regarded as part of European history, and should thus be involved in the European political process.

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.

A1 - Kliegl, Reinhold A1 - DellaRosa, Denise T1 - Spectral efficiency of blackness induction N2 - The spectral efficiency of blackness induction was measured in three normal trichromatic observers and in one deuteranomalous observer. The psychophysical task was to adjust the radiance of a monochromatic 60–120′ annulus until a 45′ central broadband field just turned black and its contour became indiscriminable from a dark surrounding gap that separated it from the annulus. The reciprocal of the radiance required to induce blackness with annulus wavelengths between 420 and 680 nm was used to define a spectral-efficiency function for the blackness component of the achromatic process. For each observer, the shape of this blackness-sensitivity function agreed with the spectral-efficiency function based on heterochromatic flicker photometry when measured with the same 60–120′ annulus. Both of these functions matched the Commission Internationale de l'Eclairage Vλ function except at short wavelengths. Ancillary measurements showed that the latter difference in sensitivity can be ascribed to nonuniformities of preretinal absorption, since the annular field excluded the central 60′ of the fovea. Thus our evidence indicates that, at least to a good first approximation, induced blackness is inversely related to the spectral-luminosity function. These findings are consistent with a model that separates the achromatic and the chromatic pathways.

Anatomical studies suggested a presinusoidal or an intrasinusoidal confluence in the first, second or even final third of the sinusoids. The objective of this investigation was to study the problem with functional biochemical techniques. Rat livers were perfused through the hepatic artery and simultaneously either in the orthograde direction from the portal vein to the hepatic vein or in the retrograde direction from the hepatic vein to the portal vein. Arterial how was linearly dependent on arterial pressure between 70 cm H2O and 120 cm H2O at a constant portal or hepatovenous pressure of 18 cm H2O. An arterial pressure of 100 cm H2O was required for the maintenance of a homogeneous orthograde perfusion of the whole parenchyma and of a physiologic ratio of arterial to portal how of about 1:3. Glucagon was infused either through the artery or the portal vein and hepatic vein, respectively, to a submaximally effective ''calculated'' sinusoidal concentration after mixing of 0.1 nmol/L. During orthograde perfusions, arterial and portal glucagon caused the same increases in glucose output. Yet during retrograde perfusions, hepatovenous glucagon elicited metabolic alterations equal to those in orthograde perfusions, whereas arterial glucagon effected changes strongly reduced to between 10% and 50%. Arterially infused trypan blue was distributed homogeneously in the parenchyma during orthograde perfusions, whereas it reached clearly smaller areas of parenchyma during retrograde perfusions. Finally, arterially applied acridine orange was taken up by all periportal hepatocytes in the proximal half of the acinus during orthograde perfusions but only by a much smaller portion of periportal cells in the proximal third of the acinus during retrograde perfusions. These findings suggest that in rat liver, the hepatic artery and the portal vein mix before and within the first third of the sinusoids, rather than in the middle or even last third.

The plant-animal interface is the most variable and least predictable of all levels in the food web. In order to study determinants of food quality in a large lake and to test the recently proposed central importance of the long-chained eicosapentaenoic acid (EPA) at the pelagic producer-grazer interface, we tested the importance of polyunsaturated fatty acids (PUFAs) at the pelagic producerconsumer interface by correlating sestonic food parameters with somatic growth rates of a clone of Daphnia galeata. Daphnia growth rates were obtained from standardized laboratory experiments spanning one season with Daphnia feeding on natural seston from Lake Constance, a large pre-alpine lake. Somatic growth rates were fitted to sestonic parameters by using a saturation function. A moderate amount of variation was explained when the model included the elemental parameters carbon (r2 = 0.6) and nitrogen (r2 = 0.71). A tighter fit was obtained when sestonic phosphorus was incorporated (r2 = 0.86). The nonlinear regression with EPA was relatively weak (r2 = 0.77), whereas the highest degree of variance was explained by three C18-PUFAs. The best (r2 = 0.95), and only significant, correlation of Daphnia's growth was found with the C18-PUFA α-linolenic acid (α-LA; C18:3n-3). This correlation was weakest in late August when C:P values increased to 300, suggesting that mineral and PUFA-limitation of Daphnia's growth changed seasonally. Sestonic phosphorus and some PUFAs showed not only tight correlations with growth, but also with sestonic α-LA content. We computed Monte Carlo simulations to test whether the observed effects of α-LA on growth could be accounted for by EPA, phosphorus, or one of the two C18-PUFAs, stearidonic acid (C18:4n-3) and linoleic acid (C18:2n-6). With >99 % probability, the correlation of growth with α-LA could not be explained by any of these parameters. In order to test for EPA limitation of Daphnia's growth, in parallel with experiments on pure seston, growth was determined on seston supplemented with chemostat-grown, P-limited Stephanodiscus hantzschii, which is rich in EPA. Although supplementation increased the EPA content 80-800x, no significant changes in the nonlinear regression of the growth rates with α-LA were found, indicating that growth of Daphnia on pure seston was not EPA limited. This indicates that the two fatty acids, EPA and α-LA, were not mutually substitutable biochemical resources and points to different physiological functions of these two PUFAs. These results support the PUFA-limitation hypothesis for sestonic C:P < 300 but are contrary to the hypothesis of a general importance of EPA, since no evidence for EPA limitation was found. It is suggested that the resource ratios of EPA and α-LA rather than the absolute concentrations determine which of the two resources is limiting growth.

Diet quality, which varies temporally and spatially in freshwater habitats, has been suggested as a significant factor influencing life history and development of freshwater invertebrates. Accordingly, experiments were conducted with field-collected larvae to test the hypothesis that diet quality can determine planktonic larval growth rates, size at settlement and subsequent post-metamorphic growth rates. Larvae were fed one of two diets or starved. One diet was composed of cyanobacterial cells which are deficient in polyunsaturated fatty acids (PUFAs), and the other was a mixed diet rich in PUFAs. Freshly metamorphosed animals from the starvation treatment had a carbon content per individual 70% lower than that of larvae fed the mixed diet. This apparent exhaustion of larval internal reserves resulted in a 50% reduction of the postmetamorphic growth rates. Growth was also reduced in animals previously fed the cyanobacterial diet. Hence, low food quantity or low food quality during the larval stage of D. polymorpha lead to irreversible effects for postmetamorphic animals, and is related to inferior competitive abilities.

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.

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.

T1 - Hegemonialmächte im Vorderen und Mittleren Orient : die Dritte Partei in internationalen Konflikten T1 - Hegemons in the Near and Middle East : the Third Party in International Conflicts N2 - During the last five decades hegemons played an important role in de-escalating international conflicts in the subregion defined as the core of Oriens Islamicus. Statistical analysis of large datasets shows that half of all conflicts remained without any interference from the hegemonial powers at all - both on global scale and in the subregion. In all other cases however, hegemons (especially super-powers in the role of patrons) tended more often to act as (power-) mediators when their client-state was engaged in conflict with a client of the opposing superpower in Oriens Islamicus than they did on global scale. They did this in their own interest in order to avoid direct involvement, i.e. possible danger of a nuclear escalation. In contrast to conventional mediation theory they were more effective in conflict de-escalation than other mediators, especially in conflicts between Israel and its Arab neighbours. The end of bipolarity in the international system also brought this mechanism of de-escalation to an end. It leaves the hegemon(s) as a potentially powerful third party on the one hand, but on the other their inclination to become involved in regional conflict remains rather diminished as long as the basic national interests in the area are not at stake.

Ulbricht demanded full support for the sovereignty of the GDR and tried to prevent any independent Polish moves to come to terms with the Federal Republic. The Polish leadership strived towards a closer economic integration with the GDR and Czechoslovakia to foster industrial development in Poland and to bind the East German state more closely into the "socialist camp". These ideas were flatly rejected by the GDR. The level of economic interdependence between the two German states and the advantages of the GDR resulting from the "intra-German" status of trade and transfer of technologies provoked Gomułka’s distrust. Relations worsened even more when, towards the end of his time in power, Ulbricht moved towards a rapprochement with the FRG and showed some readiness to question the Görlitz treaty on the German-Polish border line.

BT - Insights from four European countries T2 - Zweitveröffentlichungen der Universität Potsdam : Wirtschafts- und Sozialwissenschaftliche Reihe N2 - We investigate whether political ideology has an observable effect on decarbonization ambition, renewable power aims, and preferences for power system balancing technologies in four European countries. Based on the Energy Logics framework, we identify ideologically different transition strategies (state-centered, market-centered, grassroots-centered) contained in government policies and opposition party programs valid in 2019. We compare these policies and programs with citizen poll data. We find that ideology has a small effect: governments and political parties across the spectrum have similar, and relatively ambitious, decarbonization and renewables targets. This mirrors citizens' strong support for ambitious action regardless of their ideological self-description. However, whereas political positions on phasing out fossil fuel power are clear across the policy space, positions on phasing in new flexibility options to balance intermittent renewables are vague or non-existent. As parties and citizens agree on strong climate and renewable power aims, the policy ambition is likely to remain high, even if governments change.

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.

Since then the federal minister for development cooperation – Heidemarie Wieczorek- Zeul – presented some interesting strategic papers under the label "aid as a global policy to overcome structural blockades to social progress and development". Special emphasis was put on the Program of Action for Poverty Reduction and on the strategy paper of a new Africa policy, but neither are concrete results yet in sight nor is an answer to the burning question of what to do with half of all African countries not having a long-term perspective for development at all (the "failing states" etc.). The article shows the great discrepancy between the impressive political rhetoric and the meager budget to cope with the many challenges of the poor developing countries in Africa. The new concept of the enlarged security intends to stabilize the structural conditions for social and economic development. In order to realize this aim, the article proposes a link between public expenditures on military measures for security and such on civil measures for structural security. Finally the article asks how development cooperation can influence the political attitudes of state and society in Africa in the direction of good governance and structural reforms.

Encountering unexpected words could therefore be expected to trigger costlier shifts in these representations than expected words. However, psycholinguistic measures commonly used to study probabilistic processing, such as the N400 event-related potential (ERP) component, are sensitive to word predictability but not to contextual constraint. Some research suggests that constraint-related processing cost may be measurable via an ERP positivity following the N400, known as the anterior post-N400 positivity (PNP). The PNP is argued to reflect update of a sentence representation and to be distinct from the posterior P600, which reflects conflict detection and reanalysis. However, constraint-related PNP findings are inconsistent. We sought to conceptually replicate Federmeier et al. (2007) and Kuperberg et al. (2020), who observed that the PNP, but not the N400 or the P600, was affected by constraint at unexpected but plausible words. Using a pre-registered design and statistical approach maximising power, we demonstrated a dissociated effect of predictability and constraint: strong evidence for predictability but not constraint in the N400 window, and strong evidence for constraint but not predictability in the later window. However, the constraint effect was consistent with a P600 and not a PNP, suggesting increased conflict between a strong representation and unexpected input rather than greater update of the representation. We conclude that either a simple strong/weak constraint design is not always sufficient to elicit the PNP, or that previous PNP constraint findings could be an artifact of smaller sample size.

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.

While many studies have demonstrated the influence of personality traits on behavioral patterns, its quantification, especially in wild animal populations, remains a challenge. Only a few studies have established a link between personality and recurring movements within home ranges, although these small-scale movements are of key importance for identifying ecological interactions and forming individual niches. In this regard, differences in space use among individuals might reflect different exploration styles between behavioral types along the shy-bold continuum. Methods We assessed among-individual differences in behavior in the European hare (Lepus europaeus), a characteristic mammalian herbivore in agricultural landscapes using a standardized box emergence test for captive and wild hares. We determined an individuals’ degree of boldness by measuring the latencies of behavioral responses in repeated emergence tests in captivity. During capture events of wild hares, we conducted a single emergence test and recorded behavioral responses proven to be stable over time in captive hares. Applying repeated novel environment tests in a near-natural enclosure, we further quantified aspects of exploration and activity in captive hares. Finally, we investigated whether and how this among-individual behavioral variation is related to general activity and space use in a wild hare population. Wild and captive hares were treated similarly and GPS-collared with internal accelerometers prior to release to the wild or the outdoor enclosure, respectively. General activity was quantified as overall dynamic body acceleration (ODBA) obtained from accelerometers. Finally, we tested whether boldness explained variation in (i) ODBA in both settings and (ii) variation in home ranges and core areas across different time scales of GPS-collared hares in a wild population. Results We found three behavioral responses to be consistent over time in captive hares. ODBA was positively related to boldness (i.e., short latencies to make first contact with the new environment) in both captive and wild hares. Space use in wild hares also varied with boldness, with shy individuals having smaller core areas and larger home ranges than bold conspecifics (yet in some of the parameter space, this association was just marginally significant). Conclusions Against our prediction, shy individuals occupied relatively large home ranges but with small core areas. We suggest that this space use pattern is due to them avoiding risky, and energy-demanding competition for valuable resources. Carefully validated, activity measurements (ODBA) from accelerometers provide a valuable tool to quantify aspects of animal personality along the shy-bold continuum remotely. Without directly observing—and possibly disturbing—focal individuals, this approach allows measuring variability in animal personality, especially in species that are difficult to assess with experiments. Considering that accelerometers are often already built into GPS units, we recommend activating them at least during the initial days of tracking to estimate individual variation in general activity and, if possible, match them with a simple novelty experiment. Furthermore, information on individual behavioral types will help to facilitate mechanistic understanding of processes that drive spatial and ecological dynamics in heterogeneous landscapes.

Genetic and metabolic information of the RILs served as predictors. Feature selection reduced the number of variables (genetic and metabolic markers) in the models by more than 80% without impairing the predictive power. Thus, potential biomarkers have been revealed. Metabolites were shown to bear information on inherited macroscopic phenotypes. This proof of concept could be interesting for breeders. The example population exhibits substantial mid-parent biomass heterosis. The results of feature selection could therefore be used to shed light on the origin of heterosis. In this respect, mainly dominance effects were detected.

The principle of prohibition of retroactive laws, fixed in the 1990 German Unification Treaty and in the Constitution, had been broken in the trials against the "Mauerschützen" (border guards) in German criminal courts since 1990. There is an artificially constructed past which does not correspond to the reality of the border regime before 1989.

For Hellmann this transformation indicates "the deepest crisis of German foreign policy" ever. Hellmann proposes a rehabilitation of the tradition of the Bonner Republik and an active Idealpolitik. This summer issue of WeltTrends features eleven articles written in response to Hellmann by International Relations scholars. The debate focuses on analytical as well as normative aspects of current German foreign policy. The authors discuss the context of the European Common Foreign and Security Policy, the international system and the United Nations, historical aspects of German foreign policy and the German foreign policy discourse. While some contributors share Hellmann's idealist position, most challenge his plea from a more realist perspective. In the upcoming fall issue, this debate will be continued with contributions by German foreign policy makers. A final reply by Hellmann will complete the debate in the winter issue of WeltTrends.

Although the civil war in Aceh – a region in the north of Sumatra – has claimed thousands of victims, the incidents have not yet been adequately dealt with – neither in the public domain nor within the scientific community. In May 2003, the Indonesian president, Megawati Sukarnoputri, imposed material law on the Aceh region in order to crack down on the separatist movement Gerakan Aceh Merdeka (GAM). This step does not seem to be in line with serious concepts of democracy and is threatening the consolidation of the transformation process.

The West embraced the illusion to provide the Kosovo-Albanians with conditions for a substantial autonomy under the umbrella of an international protectorate. The Kosovo-Albanians considered the substantial autonomy as a milestone on their way to independence, while a new Yugoslav-Serbian administration counted on regaining sovereign rights in Kosovo. The escalation of the crisis provided a fresh impetus for new expectations regarding the national question. The claim to separate Kosovo from Yugoslavia had been strengthened. The Albanian role in this process remained ambiguous. Albania has to be considered as an actor and an object, and it perceives its national geopolitical and security interests as affected by the process in Kosovo. Tirana's political orientation is strongly moving towards the Euro-Atlantic community, yet hegemonic interests vis-à-vis Kosovo might play an important role besides Tirana's own limited political influence over the developments in Kosovo.

Unfortunately, the effective collective measures to prevent and to remove threats to peace and international security as laid down in the Charter of the United Nations prove to be an unreliable promise. Ever since India carried out its first nuclear tests in 1974, Pakistan has been forced into a race to catch up with the capabilities if its neighbor. Nevertheless, Pakistan chose a minimalist approach and refrained from converting its nuclear capabilities into weapon systems. Pakistan is against an arms race in the South Asian region, and opposes the concept of first use of nuclear weapons. To ensure lasting peace, a common vision on disarmament is necessary.
