The Iron Age cemetery of Münsingen in Switzerland with 220 abundantly equipped burials marked a milestone for Iron Age research. The horizontal spread throughout the time of its occupancy laid the foundation for the chronology system of the Late Iron Age. Today, skulls of 77 individuals and some postcranial bones are still preserved. The aim of the study was to obtain information about diet, mobility and social stratification of the individuals. Stable isotope ratios of carbon, nitrogen and sulphur were analysed for 63 individuals. For all of them, C3 plants were found to be the staple food. There are significant differences between males and females in δ13C and δ15N values. This points to a gender restriction in the access to animal protein with males probably having more access to meat and dairy products. Differences in δ15N values were also observed for different age classes. δ34S values indicate a terrestrial-based diet with no significant intake of marine or freshwater fish. Seven adults with enriched δ34S values might have immigrated to Münsingen, four of which were found in the oldest part of the cemetery. Furthermore, possible changes of the vegetation are indicated by the more positive stable carbon ratios in the later phases. The results lead to the suggestion that especially males buried with weapons might have played a special role in the Iron Age society. 相似文献

Boundary spanning in social and cultural geography 总被引:1,自引:0,他引:1
This article situates interactions between German- and English-language social and cultural geographies since the mid-twentieth century within their wider intellectual, political and socio-economic contexts. Based on case study examples, we outline main challenges of international knowledge transfer due to nationally and linguistically structured publication cultures, differing academic paradigms and varying promotion criteria. We argue that such transfer requires formal and informal platforms for academic debate, the commitment of boundary spanners and supportive peer groups. In German-language social and cultural geography, these three aspects induced a shift from a prevalent applied research tradition in the context of the modern welfare state towards a deeper engagement with Anglophone debates about critical and post-structuralist approaches that have helped to critique the rise of neoliberal governance since the 1990s. Anglophone and especially British social and cultural geography, firmly grounded in critical and post-structuralist thought since the 1980s, are increasingly pressurized through the neoliberal corporatization of the university to develop more applied features such as research impact and students’ employability. 相似文献

Nondestructive analyses of medieval reverse paintings on glass revealed the same dyes and pigments customarily used in panel
paintings. However, there is one exception: the black colorant is not a carbon-based pigment, but black enamel. In this respect,
the stylistic as well as the technical influence of stained glass artwork can clearly be seen on reverse paintings on glass.
However, there is a crucial difference: in reverse paintings, the black enamel is not fired onto the glass but painted (cold
painting). Additional analyses confirmed these findings. Based on these results, the art form “reverse painting on glass”
has technically to be characterized as a mixture of “stained glass” and “panel painting” that nonetheless develops into a
genre of its own. 相似文献

How are we to understand and analyse the constitutional tension in Turkey between the judiciary and the political sphere? In this article the issue is mirrored in the political crisis which started in April 2007 with the nomination of Abdullah Gül as presidential candidate by the moderate Islamist Justice and Development Party (AKP). The more detailed empirical background consists primarily of the dress code problematics including the matter of party closure. Theoretically, the “hegemonic preservation” thesis elaborated by Ran Hirschl turned out to be a useful instrument when it comes to explaining this political crisis as well as the origin of the so-called new constitutionalism. This is illustrated by the judicial activism in the headscarf affair as well as by the eagerness of the Republican People's Party (CHP), as the political representative of the secular establishment, to play the ‘Atatürk card’ and to submit the protection of their interest to an independent judiciary and not to the uncertainties of the mechanisms of majoritarian democracy. However, with regard to the current Turkish case my analysis also shows that Hirschl's thesis is too static and should be complemented with a more dynamic perspective of constitutional politics as a repeated game. One example of this is that even if the Turkish Constitutional Court (TCC) had declared the constitutional amendment on the headscarf invalid and voted for economic sanctions against the AKP, it did not close the party down. 相似文献

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 相似文献
