The history of the black German minority, now estimated at around 500,000, goes back several centuries. It is only since the twentieth century, however, that Germans of African descent have been perceived as a group. This did not lead to their recognition as a national minority, but rather, from the 1910s to the 1960s, they were defined as a collective threat to Germany's racial and cultural ‘purity’. When a sense of identity emerged among Afro‐Germans themselves in the 1980s, the majority population continued to deny the existence of ethnic diversity within German society. At the turn of the twenty‐first century, Afro‐Germans seemingly suddenly appeared as a new, ‘hip’ minority. This appearance was largely focused on the immense public success of the Hip Hop collective ‘Brothers Keepers’, conceived as an anti‐racist, explicitly Afro‐German intervention into German debates around national identity and racist violence. This article explains the success of ‘Brothers Keepers’ by contextualising it within the tradition of two decades of Afro‐ German feminist activism and the transnational Hip Hop movement of European youth of colour.  相似文献

Between 2800 and 2400 cal BC pastoralists from Central Europe migrated into the eastern Baltic paving the way for the Corded Ware Culture (CWC), and a new type of economy, animal husbandry. Traditionally the CWC people were viewed as highly mobile due to the lack of substantial traces of dwellings and material culture at settlement sites; they were reliant on an economy based on animal husbandry as demonstrated by zooarchaeological and stable isotopic evidence. However, this paradigm is beginning to shift. Here, we present new AMS radiocarbon (14C) measurements, pollen and macrobotanical data from sediment samples and a portable fish screen, as well as technological, molecular and isotopic data obtained from ceramic vessels from three CWC sites in the eastern Baltic. Overall, our results indicate a de-Neolithisation process undergone by some CWC groups, particularly in lacustrine and coastal ecotones, and a shift to hunting, gathering and fishing.  相似文献

Contemporary seismic design is based on dissipating earthquake energy through significant inelastic deformations. This study aims at developing an understanding of the inelastic behavior of braced frames of modular steel buildings (MSBs) and assessing their seismic demands and capacities. Incremental dynamic analysis is performed on typical MSB frames. The analysis accounts for their unique detailing requirements. Maximum inter-story drift and peak global roof drift were adopted as critical response parameters. The study revealed significant global seismic capacity and a satisfactory performance at design intensity levels. High concentration of inelasticity due to limited redistribution of internal forces was observed.  相似文献

Old mining and smelting features in the Abu Gerida area have been studied using field observations, microscopy and SEM–EDS to detect the ores that were exploited in antiquity. There are two groups of shafts in the area. The first group encloses secondary copper minerals and is associated with glassy slags containing copper prills. The other group is associated with hematite that was extracted and transferred to a smelting station to the west of the mining site, where iron slags and charcoal fragments are found. These slags are composed mainly of wüstite, fayalite–kirschsteinite and traces of metallic iron. Pottery fragments from this area were dated to the Ptolemaic Period, which may be the age of iron exploitation. Copper might have been exploited earlier.  相似文献

El Zakiab site yielded the earliest evidence of lungfish to be recorded from the excavated prehistoric settlements in the region of the Nile valley. The study of the osteological remains of the fish, its behaviour in the absence of water, and its ecological requirements offer evidence concerning the status of the site and its surroundings with reference to human seasonal adaptation.  相似文献
