Sozialindex für Grundschulen in Mülheim an der Ruhr

The German school system is socially highly unequal, as educational research criticized for a long time. While in some schools socially privileged pupils are the majority, other schools are composed by mostly poor pupils. The combination of socio-geographic and educational geographic considerations leads to a social school index, which clearly shows how strong schools are socially privileged or disadvantaged. The paper presents a practical example of building a social school index for cities and compares the results. The residence-based density index on grid data from German Social Code (book 2) is preferred because it is unproblematic in terms of data protection law and can be extended at the level of 100 × 100?m grids. Calculating detailed and differentiated social school indices with school enrollment data leads to very good results, but is much more work.     

Stadtgrün statt Stress

The study shows the relation between urban green and (urban) stress within the urban district Bonn, Germany. How do urban ecosystem services influence the subjective well-being? A triangulation of methods (site’s inspections, online survey) was applied to collect data on the availability and state of urban green spaces regarding the urban district of Bonn and by whom, why and how often they are visited. Of special interest could be the ecological state of the green space. The ecological state of green spaces in Bonn was assessed and connected to the results of the online survey. Thus, health effective potentials of urban green can be given. Main advantages were proved by an excellent network of green infrastructure as well as big green spaces or rather open catchment areas.     

Würzung Mit Feuer

According to the Homeric Hymn to Hermes, Hermes on the day of his birth met a tortoise, killed it and constructed the lyre from its shell. This became the orthodox version of the invention of the lyre. There are, however, some traces of another version as well, which can now be reconstructed with the help of an 11th‐century Persian verse‐romance. Here, Hermes is an adult, he finds a tortoise‐shell sounding in the wind, and then tries to imitate nature. Behind the two versions, each the creation of an individual author, one may discern the original myth.     

Grüne Infrastruktur –

Due to climate change, but also because of the demographic change and financial constraints in many municipalities, the future of cities is a currently much-discussed topic. Conflicts over land-use are inevitable: As densification is an essential principle in growing cities, the pressure on open (green) spaces rises. Climate Change and water-management as well as mobility-issues and air-quality confront municipalities with new challenges, in terms of open space planning and greenery in the city. It is necessary to save the existing green in these days of budget-shortage and other priorities in communities. Municipalities have to raise new strategies to strengthen the awareness of the value of green in public and in the local business.     

„Was für Grün in der Stadt?“

Urban green space is a key subject of actual urban negotiation processes on how the city shall develop. Visions of the ideal city are reflected in the meanings currently ascribed to urban gardening. Thereby the relation between human and nature as well as between build and natural environment in the city plays a central role. Results from different Swiss cities show that allotment gardens as well as newer forms of urban gardening are oscillating between a compensatory and a complementary understanding of nature, and they equally combine the desire for pristine nature with the demand for functional green space in the city.     

Glückliche Fügung: Experiments’ Potential to Integrate Disciplines**

This essay reviews the discipline-connecting potential of experimentation. Two examples are used to illustrate how researchers in the first half of the twentieth century profitably combined resources from different disciplines in their experiments. These experiments were designed to test mechanism models describing chemical processes underlying the behavior of biological systems. The researchers had clear expectations about how certain interventions should affect the behavior of the organisms studied, if that behavior was indeed based on the presumed chemical processes. They manipulated the organisms in the relevant ways and determined how the behavior of the organisms changed as a result.     

Martin Waldseemüller's Death Date

ABSTRACT

The subject of this article is the first extant topographical engraving of Meteora, the second largest monastic complex in Greece and one of the most spectacular landscapes in the world. This late eighteenth-century print combined cartographic principles with techniques traditionally used in Byzantine painting, which situates it within a broader vernacular Greek cartographic tradition. It can also be considered a mental map of the region as envisaged by eighteenth century monks, as well as a tool for advertising the region and its monasteries at a time of political and financial distress. As with any map, the engraving simultaneously concealed and revealed, masking difficult terrestrial conditions while showing pathways to heaven.
