We investigate the importance of geo‐strategic and commercial motives for the allocation of German aid to 138 countries over the 1973–2010 period. We find that geo‐strategic and commercial motives matter. When we relate them to the political color of the German government in general, and the Ministry for Economic Cooperation and Development and the Federal Foreign Office in particular, we find their importance to be at least as strong under the socialist leadership. Socialist leadership decreases the amount of aid commitments, controlled for other factors. 相似文献

The European Commission follows a harmonized approach for calculating structural (potential) output for EU member states that takes into account labour as an important ingredient. This article shows how the recent huge migrants’ inflow to Europe affects trend output. Due to the fact that the immigrants immediately increase the working population but effectively do not enter the labour market, we illustrate that the potential output is potentially upward biased without any corrections. Taking Germany as an example, we find that the average medium-term potential growth rate is lower if the migration flow is modelled adequately compared to results based on the unadjusted European Commission procedure. 相似文献

Experience has shown that both the assessment and implementation of new technologies in food production are challenged by negative assessments of the technologies by the public. This article seeks to deepen our understanding of the concerns that may underlie negative attitudes to various kinds of risk reduction strategy in meat production, with the aim of distinguishing between forms of risk reduction in terms of their acceptability. The paper reports the result of a focus-group study. Six focus groups with Danish citizens (N: 5–9) were conducted during May 2006. The design of the groups took a bottom-up approach and included elements of meat quality, meat safety and risk reduction strategies. The study shows the dilemma risk reduction presents to members of the public. On the one hand, people want safe meat; on the other, the study showed that with the exception of hygiene practices, people generally have an aversion to risk reduction strategies. Some variation was found, however, in the rejection of the strategies. Thus, more acceptable strategies are characterised by a low degree of technological interference, and by being close to the consumer’s experience in everyday life and/or familiar to the participants’ picture of meat production. It is also important that the strategy does not alter the quality of the end-product (meat) in an unfavourable way. The implications of the results and the inherent dilemma for meat safety policy formation are discussed. 相似文献

The “military shooter” (MS) video game is the latest in a long line of video games that immerse the player in a fantasy world. Although the MS video game was once regarded as excessively violent, it has now become socially acceptable, as the virtues of military life have become incorporated in popular culture. That transition has taken place in part because the military has begun to work closely with the producers of MS video games, such as the “Call of Duty” series, to imagine and prepare for future military threats, both on virtual battlefields and on actual terrain. The increasing use of highly paid corporate mercenaries in actual war zones has also influenced game play by introducing players to the potential for large financial rewards by becoming experts in virtual combat. Thus, MS video games incorporate players not only into the technological domain of modern warfare but also into the economic domain of fighting war for profit. In the post 9/11 era, warfare has increasingly become a strategy of risk management, in which the battlefield is less a physical space than a semiotic landscape of conflicting loyalties and financial incentives. The MS shooter game is conditioning the soldiers of the future to fight in this shadowy world that lies between the virtual and the real. All of these changes have political ramifications. In the long run, constant exposure to these games is creating a subculture that is not only immersed in an armament culture but also increasingly allied with current patterns of geopolitical domination and subordination. 相似文献

Making architectural decisions in long lifecycle systems is challenging because the time between system definition and end of operations can span multiple decades, resulting in shifts in stakeholder needs and major advances in technologies. Space-based communications using relay satellite constellations is one such example, requiring substantial up-front planning to define capabilities and size capacity due to the large investment of time and resources. Additionally, there are numerous viable system architectures. In this paper, we build on existing methods to develop a graph-based decision method to assess and explore architectural flexibility in the future evolution of long lifecycle systems. The tradespace graph defines edges between similar architectures, quantifies the switching cost between architectures, using graphs to analyse the potential system evolution pathways. In a test case on NASA communication satellites, we find that hosting government communications payloads, in particular optical payloads, on commercial satellites could reduce cost and increase flexibility of the NASA network. 相似文献

In a field experiment investigating age discrimination, pairs of men, aged 27 and 47, inquired about employment as waiters in towns across England, France, Germany and Spain. Statistically significant discrimination against the older waiter was found in all four countries, but it was considerably higher in France and Spain than in England and Germany. 相似文献
