- Generating and Visualizing a Soccer Knowledge Base (2006)
- This demo abstract describes the SmartWeb Ontology-based Information Extraction System (SOBIE). A key feature of SOBIE is that all information is extracted and stored with respect to the SmartWeb ontology. In this way, other components of the systems, which use the same ontology, can access this information in a straightforward way. We will show how information extracted by SOBIE is visualized within its original context, thus enhancing the browsing experience of the end user.
- Price stability, inflation convergence and diversity in EMU : does one size fit all? (2005)
- Using a unique data set of regional inflation rates we are examining the extent and dynamics of inflation dispersion in major EMU countries before and after the introduction of the euro. For both periods, we find strong evidence in favor of mean reversion (ß-convergence) in inflation rates. However, half-lives to convergence are considerable and seem to have increased after 1999. The results indicate that the convergence process is nonlinear in the sense that its speed becomes smaller the further convergence has proceeded. An examination of the dynamics of overall inflation dispersion (ó-convergence) shows that there has been a decline in dispersion in the first half of the 1990s. For the second half of the 1990s, no further decline can be observed. At the end of the sample period, dispersion has even increased. The existence of large persistence in European inflation rates is confirmed when distribution dynamics methodology is applied. At the end of the paper we present evidence for the sustainability of the ECB's inflation target of an EMU-wide average inflation rate of less than but close to 2%. Klassifikation: E31, E52, E58
- Inflation rate dispersion and convergence in monetary and economic unions : lessons for the ECB (2005)
- Using a set of regional inflation rates we examine the dynamics of inflation dispersion within the U.S.A., Japan and across U.S. and Canadian regions. We find that inflation rate dispersion is significant throughout the sample period in all three samples. Based on methods applied in the empirical growth literature, we provide evidence in favor of significant mean reversion (ß-convergence) in inflation rates in all considered samples. The evidence on ó-convergence is mixed, however. Observed declines in dispersion are usually associated with decreasing overall inflation levels which indicates a positive relationship between mean inflation and overall inflation rate dispersion. Our findings for the within-distribution dynamics of regional inflation rates show that dynamics are largest for Japanese prefectures, followed by U.S. metropolitan areas. For the combined U.S.-Canadian sample, we find a pattern of within-distribution dynamics that is comparable to that found for regions within the European Monetary Union (EMU). In line with findings in the so-called 'border literature' these results suggest that frictions across European markets are at least as large as they are, e.g., across North American markets.

- How wide are European borders? : new evidence on the integration effects of monetary unions (2001)
- We use consumer price data for 81 European cities (in Germany, Austria, Switzerland, Italy, Spain and Portugal) to study deviations from the law-of-one-price before and during the European Economic and Monetary Union (EMU) by analysing both aggregate and disaggregate CPI data for 7 categories of goods we find that the distance between cities explains a significant amount of the variation in the prices of similar goods in different locations. We also find that the variation of the relative price is much higher for two cities located in different countries than for two equidistant cities in the same country. Under EMU, the elimination of nominal exchange rate volatility has largely reduced these border effects, but distance and border still matter for intra-European relative price volatility.

- Economic integration and the exchange rate regime : how damaging are currency crises? (2001)
- We use consumer price data for 205 cities/regions in 21 countries to study deviations from the law-of-one-price before, during and after the major currency crises of the 1990s. We combine data from industrialised nations in North America (Unites States, Canada, Mexico), Europe (Germany, Italy, Spain and Portugal) and Asia (Japan, Korea, New Zealand, Australia) with corresponding data from emerging market economies in the South America (Argentine, Bolivia, Brazil, Columbia) and Asia (India, Indonesia, Malaysia, Philippines, Taiwan, Thailand). We confirm previous results that both distance and border explain a significant amount of relative price variation across different locations. We also find that currency attacks had major disintegration effects by significantly increasing these border effects, and by raising within country relative price dispersion in emerging market economies. These effects are found to be quite persistent since relative price volatility across emerging markets today is still significantly larger than a decade ago.

- Measurements of proton-induced reactions on ruthenium-96 in the ESR at GSI (2011)
- 8th International Conference on Nuclear Physics at Storage Rings Stori11, October 9-14, 2011 Laboratori Nazionale di Frascati, Italy. Storage rings offer the possibility of measuring proton- and alpha-induced reactions in inverse kinematics. The combination of this approachwith a radioactive beamfacility allows, in principle, the determination of the respective cross sections for radioactive isotopes. Such data are highly desired for a better understanding of astrophysical nucleosynthesis processes like the p-process. A pioneering experiment has been performed at the Experimental Storage Ring (ESR) at GSI using a stable 96Ru beam at 9-11 AMeV and a hydrogen target. Monte-Carlo simulations of the experiment were made using the Geant4 code. In these simulations, the experimental setup is described in detail and all reaction channels can be investigated. Based on the Geant4 simulations, a prediction of the shape of different spectral components can be performed. A comparison of simulated predictions with the experimental results shows a good agreement and allows the extraction of the cross section.

- Economic integration and the exchange rate regime : how damaging are currency crises? (2003)
- We use consumer price data for 205 cities/regions in 21 countries to study PPP deviations before, during and after the major currency crises of the 1990s. We combine data from industrialized nations in North America (Unites States, Canada and Mexico), Europe (Germany, Italy, Spain and Portugal), Asia (Japan and South Korea), and Oceania (Australia and New Zealand) with corresponding data from emerging market economies in South America (Argentina, Bolivia, Brazil, Columbia) and Asia (India, Indonesia, Malaysia, Philippines, Taiwan, Thailand). By doing so, we confirm previous results that both distance and border explain a significant amount of relative price variation across different locations. We also find that currency attacks had major disintegration effects by considerably increasing these border effects and by raising within-country relative price dispersion in emerging market economies. These effects are found to be quite persistent since relative price volatility across emerging markets today is still significantly larger than a decade ago.

- Die Säuger (1993)
- Die stark strukturierte Niederungslandschaft des Drömlings bietet über 40 Säugetierarten Lebensraum. In der Roten Liste der Säugetiere des Landes Sachsen-Anhalt (Stand: Mai 1992) sind 21 der bisher festgestellten Arten als gefährdet. stark gefährdet bzw. vom Aussterben bedroht geführt. Charakteristisch für das Gebiet ist das Vorkommen des Fischotters (Lutra lutra). Zum Schutz dieser vom Aussterben bedrohten Art wurde 1979 im Drömling eine Fläche von 1917 ha als Fischotterschongebiet ausgewiesen (338 WEBER). Heute wird der Otterbestand im Naturpark auf der Grundlage der Verteilung aktueller Nachweise auf 2-3 Reviere geschätzt.
