  abstract  = {The European potential for renewable electricity is sufficient to enable fully renewable supply on different scales, from self-sufficient, subnational regions to an interconnected continent. We not only show that a continental-scale system is the cheapest, but also that systems on the national scale and below are possible at cost penalties of 20\% or less. Transmission is key to low cost, but it is not necessary to vastly expand the transmission system. When electricity is transmitted only to balance fluctuations, the transmission grid size is comparable to today's, albeit with expanded cross-border capacities. The largest differences across scales concern land use and thus social acceptance: in the continental system, generation capacity is concentrated on the European periphery, where the best resources are. Regional systems, in contrast, have more dispersed generation. The key trade-off is therefore not between geographic scale and cost, but between scale and the spatial distribution of required generation and transmission infrastructure.},

  abstract  = {Schulische und vor allem unterrichtliche Implementationsprozesse zielen zumeist auf die Professionalisierung der Lehrkr{\"a}fte ab. Die intendierte Ver{\"a}nderung des Unterrichts beginnt dabei mit einer gew{\"u}nschten Ver{\"a}nderung von Einstellungen und Verhaltensweisen der Lehrkr{\"a}fte, welche erst zu einer ver{\"a}nderten Handlungsroutine in der Arbeitspraxis f{\"u}hren kann. Das Modell der Stages of Concern von Hall und Hord (2006) stellt eine der wenigen M{\"o}glichkeiten dar, die individuelle Perspektive der Lehrkr{\"a}fte im Implementationsprozess modellbasiert und standardisiert zu untersuchen. Der vorliegende Beitrag betrachtet anhand dieses Modells die affektiv-kognitive Auseinandersetzung der Beteiligten im Implementationsprozess sowie deren Zusammenh{\"a}nge mit verschiedenen Aspekten der Kommunikation und der wahrgenommenen Entwicklung. Auf Basis einer Stichprobe von N = 66 Lehrkr{\"a}ften kann dabei gezeigt werden, dass insbesondere die Aspekte H{\"a}ufigkeit der Kooperation, Kommunikation im Kollegium und Erfahrungen im Team die affektiv-kognitive Auseinandersetzung vorhersagen. Diese Auseinandersetzung - insbesondere mit den Konsequenzen der Neuerung - bedingt wiederum die wahrgenommene Entwicklung im Implementationsprozess.},

This article presents a comparison between subjects restricted to playing pure strategies and subjects allowed to play mixed strategies in a one-shot symmetric PD laboratory experiment. Subjects interact with 10 other subjects and take their decisions all at once. Because subjects in the mixed-strategy treatment group are allowed to condition their level of cooperation more precisely on their beliefs about their counterparts' level of cooperation, we predicted the cooperation rate in the mixed-strategy treatment group to be higher than in the pure-strategy control group. The results of our experiment reject our prediction: even after controlling for beliefs about the other subjects' level of cooperation, we find that cooperation in the mixed-strategy group is lower than in the pure-strategy group. We also find, however, that subjects in the mixedstrategy group condition their cooperative behaviour more closely on their beliefs than in the pure-strategy group. In the mixed-strategy group, most subjects choose intermediate levels of cooperation.},

  abstract  = {Public debate about energy relations between the EU and Russia is distorted. These distortions present considerable obstacles to the development of true partnership. At the core of the conflict is a struggle for resource rents between energy producing, energy consuming and transit countries. Supposed secondary aspects, however, are also of great importance. They comprise of geopolitics, market access, economic development and state sovereignty. The European Union, having engaged in energy market liberalisation, faces a widening gap between declining domestic resources and continuously growing energy demand. Diverse interests inside the EU prevent the definition of a coherent and respected energy policy. Russia, for its part, is no longer willing to subsidise its neighbouring economies by cheap energy exports. The Russian government engages in assertive policies pursuing Russian interests. In so far, it opts for a different globalisation approach, refusing the role of mere energy exporter. In view of the intensifying struggle for global resources, Russia, with its large energy potential, appears to be a very favourable option for European energy supplies, if not the best one. However, several outcomes of the strategic game between the two partners can be imagined. Engaging in non-cooperative strategies will in the end leave all stakeholders worse-off. The European Union should therefore concentrate on securing its partnership with Russia instead of damaging it. Stable cooperation would need the acceptance that the partner may pursue his own goals, which might be different from one's own interests. The question is, how can a sustainable compromise be found? This thesis finds that a mix of continued dialogue, a tit for tat approach bolstered by an international institutional framework and increased integration efforts appears as a preferable solution.},
