Islamophobia is more strongly developed in East Germany compared to the western part of the country. Given the lack of personal contact with Muslims in East Germany, islamophobia is probably strongly influenced by media coverage. For this reason, the coverage of two East German regional newspapers, Nordkurier and Volksstimme, is analyzed against the theoretical background of a conjunction of the social-psychological stereotype content model with the communication-scientific concept of framing. Using content analysis and latent class analysis, two so-called stereotype frames were identified. Two thirds of all Islam-related articles use the ??cold and harm frame??. Here, Muslims are often blamed for the lethal consequences of terrorist action, their behaviour is evaluated as cold or immoral, and military interventions against them are discussed. On the other hand, one third of all Islam-related articles belongs to the ??competence and cooperation frame??. Competence is ascribed to Muslims as their success in artistic, athletic or political activities is recognized and other actors?? interest in cooperation in these areas is emphasized. Whereas the ??cold and harm frame?? probably promotes medial segregation, the ??competence and cooperation frame?? is representing an assimilative model of media integration.  相似文献

Facing the challenge of climate change, innovations that imply environmental benefits create business opportunities for entrepreneurs. This paper analyzes innovation capabilities of startups in Cleantech and how the innovation outcomes of those startups develop over time. Based on the Mannheim Foundation Panel and applying propensity score matching, a cohort of 567 Cleantech startups is analyzed and compared with a control cohort of non‐Cleantech startups. We find that startups in Cleantech have, on average, higher technological capabilities compared with all other startups. Our econometric evidence shows that Cleantech startups are more likely to combine existing technology in a novel way. Finally, we find that Cleantech startups develop more market novelties in subsequent years when compared with their control group peers.  相似文献

Abstract. We analyze the relationship between per capita income and foreign aid. We employ annual data and five‐year averages and carefully examine the time‐series properties of the data. Panel estimations with dynamic feasible generalized least‐squares (DFGLS) show that aid generally has an insignificant or minute negative significant impact on per capita income (particularly in highly aid‐dependent countries). This holds true for countries with different levels of human development and income, as well as for different regions. We also find that aid has a small positive impact on investment, but a significant negative impact on domestic savings (crowding out) and the real exchange rate (appreciation).

The liberalization of ground handling in Europe forces airports to assess their performance relative to their competitors in order to remain competitive and sustain long-term competitive advantage. Together with main EU hub airports, action research was conducted for one year to develop a holistic performance measurement system (PMS) for ramp services. The resulting PMS entails a process-based perspective and reflects the supply chain of airport logistics. As the findings of an ex-post validation suggest, the system represents a suitable basis for competitive benchmarking activities.  相似文献

Experiments conducted in the US and France were used to study how individuals make trade-offs between health and taste for themselves and others. When someone receives a choice made for them that differs from their preference, they experience a welfare loss; at least in the short-term. We measure the empirical magnitude of this loss, and suggest it play a role in assessing the desirability of paternalistic policies motivated by behavioural economics. We show that the welfare loss changes with the provision of new information and the impact of this information differs for the two countries.  相似文献

We analyze the drivers of audience size and the number of questions asked in parallel sessions at the annual conference of the German Economics Association. We find that the location of the presentation is at least as important for the number of academics attending a talk as the combined effect of the person presenting and the paper presented. Being a presenter in a late morning session on the second day of a conference, close to the place where coffee is served, significantly increases the size of the audience. When it comes to asking questions, location becomes less important, but smaller rooms lead to more questions being asked. Younger researchers and very senior researchers attract more questions and comments. There are also interesting gender effects. Women attend research sessions more diligently than men, but seem to ask fewer questions than men. Men are less likely to attend presentations on health, education, welfare and development economics than women. Our findings suggest that strategic scheduling of sessions could ensure better participation at conferences. Moreover, different behaviors of men and women at conferences might also contribute to the lack of women in senior scientist positions.  相似文献

Using time-series cross-section data from the manufacturing sector of the 11 West German 'Bundesländer' (Federal States) from 1970 to 1996, I examine the impact of public capital on private production. My econometric analysis explicitly takes into account four of the most frequent specification issues in the context of time-series crosssection data analysis: serial correlation, groupwise heteroscedasticity, cross-sectional correlation and non-stationarity of data. For all approaches and tested specifications, I find that public capital is a significant input for production in the manufacturing sector. Moreover, I find that differences in public capital endowment can explain long-term differences in productivity across the Bundesländer. One tentative conclusion that can be drawn from this finding is that differences in public capital endowment might also explain a part of the still-existing productivity gap between manufacturing in East and West Germany. However, I emphasise that the existence of positive effects of public capital on private production is a necessary, but not a sufficient condition for concluding that public investments should be boosted in the future.  相似文献

The paper discusses global current account imbalances in the context of an asymmetric world monetary system. It identifies the USA and Germany as center countries with rising/high current account deficits (USA) and surpluses (Germany). These are matched by current account surpluses of countries stabilizing their exchange rates against the dollar (dollar periphery) and current account deficits of countries stabilizing their exchange rates against the euro or members of the euro area (euro periphery). The paper finds that changes of world current account positions are closely linked to the monetary policy decision patterns both in the centers and peripheries. Whereas in the centers current account positions are affected by monetary policies, in the peripheries exchange rate stabilization cum sterilization matters. In specific, monetary expansion in the USA as well as exchange rate stabilization and sterilization policies in the dollar periphery are found to have contributed to global imbalances.  相似文献
