Selected AbstractsDie Zweckentfremdung des kommunalen Kassenkredits , eine rechtlich-ökonomische AnalysePERSPEKTIVEN DER WIRTSCHAFTSPOLITIK, Issue 2 2010Christoph Gröpl This development suggests that this debt instrument has been diverted from its original purpose, namely as an instrument of bridging short-run liquidity shortfalls. In this paper we analyze the reasons for this development , from a legal and institutional perspective on the one hand, and from an economic perspective on the other hand. One key result of the analysis is that this development is partly due to the lacking intervention of municipal supervision institutions from the Länder (German Federal States). Obviously, the Länder tolerate the abuse of the Kassenkredit in order to avoid more open types of debt. In addition, we investigate how the introduction of the doubly-entry bookkeeping in the municipalities affects the (improper) use of short-term liquidity credits. Finally, we point to the potential of the municipal Kassenkredit as a loophole in the new German constitutional debt brake. [source] Balances of phosphorus and nitrogen in carp pondsFISHERIES MANAGEMENT & ECOLOGY, Issue 1-2 2000R. Knösche The impact of carp pond effluents on natural waters was investigated in the German federal states of Brandenburg, Saxony and Bavaria, and in Hungary. Data from 38 ponds (size = 0.25,122 ha) were available for the calculation of inlet,outlet differences. An average difference of 0.51 kg phosphorus (P) ha,1 year,1 was obtained. This means that every hectare of pond surface releases 510 g P less than it receives from the incoming water. This result was independent of the amount of fish harvested (, 1500 ha,1 year,1). The average retention of P (P-balance) was 5.71 kg P ha,1 year,1. Phosphorus retention increased with increasing intensity of production. Nitrogen (N) retention increased with production intensity from 78.5 kg ha,1 year,1 in German standard ponds to >,290 kg N ha,1 year,1in pig-cum-fish ponds in Hungary. A predominantly mineralized sludge suspension is released during harvesting at loads below 1% of the retention capacity of the pond. Under usual pond management regimes, the sludge load during harvesting ranged from 50 to 200 L ha,1, equivalent to 0.3,9.3 g dry matter ha,1. The present study suggests that ponds are not a burden on the environment. By contrast, these water bodies improve water quality. Therefore, pressures to reduce the intensity of pond production cannot be justified on the basis of supposed impacts on water quality. However, even if loads during harvesting are low compared with the retention capacity of the pond, more effort should be carried out to reduce the pollution of streams by pond outlets downstream. This can be done by limiting pond drainage to periods when the suspended material has settled or by short-term sedimentation of the sludge in a settling pond downstream of the rearing facility. [source] Educational Federalism in Germany: Foundations of Social Inequality in EducationGOVERNANCE, Issue 1 2009MARKUS FREITAG This article applies Fuzzy Set Qualitative Comparative Analysis to examine how sub-national education systems affect the extent of social inequality in education within the German federal states. Variations in educational outcomes between the federal states can be primarily attributed to the strict educational decentralization in Germany. We examine four conditions of regional education systems presumed to be relevant for the extent of social inequality in education: the availability of early childhood education, the development of all-day schools, the onset of tracking to different school types, and the degree of tripartition in secondary education. Altogether, we find systematic relationships between the variation of sub-national education systems and the extent of social inequality in education. The results indicate that well-developed early childhood education is necessary for a low degree of educational inequality. However, educational inequality is not directly related to partisan and socioeconomic determinants. [source] Predicting habitat distribution and frequency from plant species co-occurrence dataJOURNAL OF BIOGEOGRAPHY, Issue 6 2007Christine Römermann Abstract Aim, Species frequency data have been widely used in nature conservation to aid management decisions. To determine species frequencies, information on habitat occurrence is important: a species with a low frequency is not necessarily rare if it occupies all suitable habitats. Often, information on habitat distribution is available for small geographic areas only. We aim to predict grid-based habitat occurrence from grid-based plant species distribution data in a meso-scale analysis. Location, The study was carried out over two spatial extents: Germany and Bavaria. Methods, Two simple models were set up to examine the number of characteristic plant species needed per grid cell to predict the occurrence of four selected habitats (species data from FlorKart, http://www.floraweb.de). Both models were calibrated in Bavaria using available information on habitat distribution, validated for other federal states, and applied to Germany. First, a spatially explicit regression model (generalized linear model (GLM) with assumed binomial error distribution of response variable) was obtained. Second, a spatially independent optimization model was derived that estimated species numbers without using spatial information on habitat distribution. Finally, an additional uncalibrated model was derived that calculated the frequencies of 24 habitats. It was validated using NATURA2000 habitat maps. Results, Using the Bavarian models it was possible to predict habitat distribution and frequency from the co-occurrence of habitat-specific species per grid cell. As the model validations for other German federal states were successful, the models were applied to all of Germany, and habitat distribution and frequencies could be retrieved for the national scale on the basis of habitat-specific species co-occurrences per grid cell. Using the third, uncalibrated model, which includes species distribution data only, it was possible to predict the frequencies of 24 habitats based on the co-occurrence of 24% of formation-specific species per grid cell. Predicted habitat frequencies deduced from this third model were strongly related to frequencies of NATURA2000 habitat maps. Main conclusions, It was concluded that it is possible to deduce habitat distributions and frequencies from the co-occurrence of habitat-specific species. For areas partly covered by habitat mappings, calibrated models can be developed and extrapolated to larger areas. If information on habitat distribution is completely lacking, uncalibrated models can still be applied, providing coarse information on habitat frequencies. Predicted habitat distributions and frequencies can be used as a tool in nature conservation, for example as correction factors for species frequencies, as long as the species of interest is not included in the model set-up.
