Die Entwicklung der Sozialgeschichte der modernen Mathematik und Naturwissenschaft und die Frage nach dem sozialen Raum zwischen Disziplin und Wissenschaftler

The use of the concept of social history of science is sketched in the Anglo‐American and the German discussions from the mid 1970s up to recent work. By presenting a ‘social map’ of a selected scientific community it is argued that between the categories of discipline and single scientist there exists a wide ‘social space’ of groups within which science is pursued. In adopting a milieu theoretic approach an ecology of science is proposed as a suitable extension of the social history of science.     

A Multi‐Method Database of the Black and White Marbles of Göktepe (Aphrodisias), Including Isotopic,EPR, Trace and Petrographic Data

A database of the ancient marbles of Göktepe near Aphrodisias is reported, and includes 160 white, black and bichrome samples from 13 quarries and two waste deposits. The quarries are grouped into four districts. Districts 1 and 2, to the north, produced exclusively black or dark grey marbles (nero antico). Districts 3 and 4 produced white statuary marble. Nero antico and a black and white stone were also quarried in district 4, where the black marble surfaces again. The samples were characterized using petrography, isotopic analysis, EPR spectroscopy and trace analysis. The Göktepe white exhibits an unparalleled combination of fine grain, low EPR intensity and high strontium concentration that often allows easy identification. The isotopic values are less distinctive and similar to those for Carrara. In most cases, however, they are tightly grouped and also quite indicative. The black marbles exhibit a much weaker metamorphic overprint. With respect to the white marbles, they show analytical similarities but also notable differences. Therefore, establishing their provenance can be more difficult and may require the support of petrographic analysis. The results suggest that the Göktepe marbles were among the most prized and widespread statuary marbles used in Roman times, particularly from the early second century ad onwards.     

Präzision versus Exaktheit: Konfligierende Ideale der angewandten mathematischen Forschung: Das Beispiel der Tragflügeltheorie

It is often supposed that mathematical argument provides a model of precision for the sciences. In contrast to this view, the present article proposes to distinguish between mathematical exactness as a (historically variable) ideal regulating the inner standards of mathematical argumentation and precision as a (historically variable) norm governing the relation between products of mathematical reasoning in scientific contexts and empirical or practical data. By discussing a major achievement in the mathematization of flight, Ludwig Prandtl's lifting line theory of wings, it is shown that exact reasoning does not necessarily lead to scientific precision, and that the achievement of precision may even require to loosen existing standards of exactness. It is argued that the main contribution of mathematical argument to generating precision in science lies in its capacity to provide sophisticated tools for the production of data, rather than in its adherence to an ideal of exactness.     

Mössbauer Spectroscopic and Chromaticity Analysis on the Colourative Mechanism of Ancient Goryeo Celadon from GangJin and Buan

In ancient Goryeo celadon excavated from the kiln sites in the GangJin and Buan areas, the effect of the chemical composition and ionic state of Fe on the colour was evaluated by Mössbauer spectroscopy and chromaticity analysis. According to chromaticity analysis, the L* value (brightness) of the glaze was shown to be affected more by TiO₂ and MnO than by Fe₂O₃, and the body was affected more by Fe₂O₃ than by TiO₂. The a* value was found to be affected by Fe₂O₃ and TiO₂ in the glaze, whereas there was hardly any change in the body according to the composition. As for the b* value, changes due to the composition were shown to be smaller than those for the L* and a* values. According to the Mössbauer spectroscopy results, as the quantities of TiO₂ and Fe₂O₃ are increased, Fe²⁺/Fe³⁺ decreases; while the changes in Fe²⁺/Fe³⁺ with MnO and P₂O₅ are negligible. As the quantity of Fe²⁺/Fe³⁺ increases, the a* and b* values decrease, which results in the change of colour from red–yellow to blue–green. The characteristic green colour can be attributed to increased L* (brightness) and decreased a* and b* values (blue–green shift) due to the reduced Fe ion, which is mainly determined by the TiO₂ and Fe₂O₃ contents.     

Between the Mediterranean and the Atlantic: nautical iconography in the south‐west Iberian Peninsula

This study presents two new representations of ships, recently found in Casas del Turuñuelo, Spain, and dated to the end of the 5th century BC. They depict river barges, which supports the importance of river navigation in structuring the central Guadiana region in the Tartessian era. The systematization of all known ship iconography found in the area from the Early Iron Age makes it possible to highlight their homogeneity, and their Mediterranean hallmark. This serves to emphasize the interconnectivity that existed in Iberia's south‐west, fostering a process of cultural hybridization of which the vessels were both result and vehicle.     

Riding Routes and Itinerant Borders: Autonomy of Migration and Border Externalization

Despite technological upgrading of borders at the edges of Europe, “Fortress Europe” continues to fail as an effective means of controlling irregular migration. As a consequence, European states are restructuring their border regimes by externalizing migration management to non‐EU countries beyond the border and creating new programs and policies to do so. Autonomy of Migration (AoM) offers a distinct way for thinking about border control mechanisms and goals of managing mobility. AoM does not read this off‐shoring of borders through the lens of centralized and coordinated state powers, but develops an autonomous gaze that supplements these institutional readings of apparatuses of capture with a view that takes as its starting point the ways in which border architectures, institutions, and policies interact with and react to the turbulence of migrant mobilities. By engaging current EU externalization policies, this paper illustrates the shifting relationship between border control and mobility.     

Disziplinerneuerung und Universitätsreform: Das Ius publicum Romano Germanicum

What caused the reforms which permitted the universities in the Holy Roman Empire to become leading places of scientific communication and mental orientation for centuries? In most cases, outside influences - pressures from governments, princes, scholars, councillors, consistories, or, as we would say today, state and churches - were decisive. But some reforms were the consequences of paradigm-changes within the universities themselves. Such shifts were less likely to originate with faculties concerned with medicine or the natural sciences than with those which were concerned directly with the political community or human societies. This changed only in the nineteenth century, which cannot be dealt with here.     

“Aufrechterhaltung der gemeinsamen Kultur”. Die Deutsche Forschungsgemeinschaft und die Österreichisch‐Deutsche Wissenschaftshilfe in der Zwischenkriegszeit

“Maintaining a Common Culture” – The German Research Foundation and the Austrian‐German Scientific Aid in the Interbellum. After the end of the Great War, private as well as public research funding in Austria was anaemic and slow to develop. Whereas the German state‐funded Deutsche Forschungsgemeinschaft (DFG) was established as early as 1920, first steps in that direction were only taken in Austria in the late 1920s. In 1929, the Österreichisch‐deutsche Wissenschaftshilfe (ÖDW) was founded under the auspices of the Austrian Academy of Sciences and the DFG. Although prima facie on an equal footing, the new research funding organisation was in fact highly dependent on its German cooperation partner. The article explores for the first time ÖDW's position within the German and Austrian science and foreign policies, which aimed to promote the idea of unification of both states within the German Reich. A quantitative analysis of the subsidies policy in the first five years of existence shows that the ÖDW gave financial aid primarily to conservative research fields‘ affecting the intellectual balance of power in the First Austrian Republic. Policy continuities and discontinuities of the organisation in the course of the national‐socialist rise to power in Germany after 1933 are examined in the second part of the article. The article thus both increases our knowledge about the most important German research funding organisation DFG‘ and identifies some of the fundamental structural features of Austrian science policy in the interwar years.     

3D numerical modeling of hydrothermal processes during the lifetime of a deep geothermal reservoir

Understanding hydrothermal processes during production is critical to optimal geothermal reservoir management and sustainable utilization. This study addresses the hydrothermal (HT) processes in a geothermal research doublet consisting of the injection well E GrSk3/90 and production well Gt GrSk4/05 at the deep geothermal reservoir of Groß Schönebeck (north of Berlin, Germany) during geothermal power production. The reservoir is located between ?4050 to ?4250 m depth in the Lower Permian of the Northeast German Basin. Operational activities such as hydraulic stimulation, production (T = 150°C; Q = ?75 m³ h^?1; C = 265 g l^?1) and injection (T = 70°C; Q = 75 m³ h^?1; C = 265 g l^?1) change the HT conditions of the geothermal reservoir. The most significant changes affect temperature, mass concentration and pore pressure. These changes influence fluid density and viscosity as well as rock properties such as porosity, permeability, thermal conductivity and heat capacity. In addition, the geometry and hydraulic properties of hydraulically induced fractures vary during the lifetime of the reservoir. A three‐dimensional reservoir model was developed based on a structural geological model to simulate and understand the complex interaction of such processes. This model includes a full HT coupling of various petrophysical parameters. Specifically, temperature‐dependent thermal conductivity and heat capacity as well as the pressure‐, temperature‐ and mass concentration‐dependent fluid density and viscosity are considered. These parameters were determined by laboratory and field experiments. The effective pressure dependence of matrix permeability is less than 2.3% at our reservoir conditions and therefore can be neglected. The results of a three‐dimensional thermohaline finite‐element simulation of the life cycle performance of this geothermal well doublet indicate the beginning of thermal breakthrough after 3.6 years of utilization. This result is crucial for optimizing reservoir management. Geofluids (2010) 10 , 406–421     

“GREEN FIX” AS CRISIS MANAGEMENT. OR,IN WHICH WORLD IS MALMÖ THE WORLD'S GREENEST CITY?

As economic and ecological crises evolve in combination, some policy strategies might aim at killing the two birds with one stone. One recent example can be found in Malmö, Sweden, where crisis management has operated, we propose, as a green fix. The district of Västra hamnen (Western Harbour) is at the centre of the reinvention of the city: once the home of a world‐leading shipyard, it is now a no less prominent neighbourhood of ecological virtues. Through outlining the history of Malmö in general and the Western Harbour in particular, we identify how the municipality and local capital in concert increasingly used “green” strategies in the urban policies that started as crisis management in the 1990s. Today Malmö is reckoned to be among the world's greenest cities, and we reflect on the importance of this international recognition for the city. Finally, we develop a critique of the green fix as concealing crucial factors of scale, and hence running the risk of myopia.     

Österreichische Ärzteemigration 1934-1945 - Zwischen neuem Tätigkeitsgebiet und organisierten Rückkehrplänen

Information on emigrant doctors and university teachers of medicine from Austria is rather poor up to now. This article is a preliminary sketch to give a first impression of the problems, quantity and quality of the doctors' emigration. First, there is made a distinction between different groups of emigrants, who emigrated at different times owing to the political changes in Austria (civil war and ?Anschluß”?). Then the emigration prior to the political set-ups during the thirties is discussed. The assertion is made, that the reasons for emigrating during the twenties are very much the same than in later years. Hostility against Jews, socialists, democrats and foreigners made living and working conditions increasingly unbearable. Concerning the influence of emigrated scientists on science and learning in immigration countries some theoretical and clinical sub-specialties of medicine are examined, e.g. social medicine, internal medicine, pharmacology, orthopedic surgery and child psychiatry. Whereas in some cases the influence is minimal, e.g. social medicine, other disciplines have been influenced enormously, e.g. child psychiatry. Finally there follows a short examination of the organisations of Austrian doctors and medical scientists in the United States and Great Britain.     

The Edesö Wreck: the hull of a small,armed ship wrecked in the Stockholm archipelago in the latter half of the 17th century

In 2003 a well‐preserved shipwreck was found north of Dalarö in the Stockholm archipelago. In 2007 and 2008 the site was surveyed jointly by archaeologists from the Swedish National Maritime Museum, Södertörn University and the University of Southampton. The surface finds were inventoried and drawings produced of the hull structure, which measures 20 m between the posts. This paper presents the results of recording the hull. The original name of the ship, as well as the precise history of its demise, are unknown, but it appears to have been a small man‐of‐war, built and probably sunk in the late 17th century. It was possibly built in England, or at least in the English fashion of that time.
