This article narrates the experiences of white English-speaking South African Prisoners-of-War in Dresden Work Camp 1169 during the Second World War. Work Camp 1169 was populated predominantly by South African servicemen, and the availability of their memoirs and diaries, as well as first-hand interviews with some of the former inmates of this camp, provide an opportunity to analyse their experiences in terms of national identity, how well they adapted to captivity and how they managed relationships between themselves, their captors and the German citizens with whom they came into contact.  相似文献

Numerous reports of successful radiocarbon dating of cremated bones have emerged during the last decade. The success of radiocarbon dating cremated bones depends on the temperature during burning and the degree of recrystallisation of the inorganic bone matrix. During cremation bones undergo major morphological and mineralogical changes which have raised some interesting questions and discussion on the origin of the carbon source in archaeologically cremated bones. Recent laboratory experiments reveal that the properties of the combustion atmosphere play a significant role regarding the source carbon in cremated bones. Thus radiocarbon dating cremated bones is potentially dating the wood used for the cremation fire. Here we compare a high precision radiocarbon dated human bone with an associated dendrochronological age from an oak coffin. We find that the age discrepancy between the dendrochronological age and the cremated bone of 73 ± 26 14C yr is best accounted for by the so called ‘old wood’ effect.  相似文献

The use of red pigments linked to burial practices is widely documented in the Iberian prehistoric record and very often it has been traditionally interpreted as a ritual practice entailing the utilisation of local raw materials (iron oxides). Some research works, nevertheless, have also detected the use of red pigments which can only be interpreted as allochthonous. The red pigments spread over a single inhumation in a monumental Megalithic tomb surrounding Valencina de la Concepción Copper Age settlement was studied by means of X-ray diffraction, field emission scanning electron microscopy with energy dispersive X-ray spectroscopy, X-ray microfluorescence, micro-Raman and Fourier transform infrared spectroscopies. This approach allowed characterising the red pigments as cinnabar, mixed with tiny amounts of iron oxides. The presence of cinnabar, a product that was necessarily imported, in a context of an exceptional set of grave goods, suggests that the use of cinnabar was linked not only to ritual but also to practices related to the display of social status.  相似文献

Zooarchaeological analyses often rely on bone fragmentation, cut marks, and other taphonomic indicators to bolster interpretations of resource intensification that are based on observed changes in prey types and frequencies. While these taphonomic indicators are assumed to be good proxy measures of processing effort, this assumption is based on inadequate actualistic data and analysts often conflate one or more taphonomic indicators as manifestations of the same process. In this paper, we present zooarchaeological data from two villages occupied by Central African forest foragers with very different foraging efficiencies. These data provide the first case where known disparities in diet breadth and foraging efficiency are matched with prey assemblages and taphonomic attributes. Observational and quantitative data show differences between the villages in diet breadth and access to high-ranked prey, but specific taphonomic indicators such as cut mark distribution and intensity do not match predictions generated from models of resource intensification. We propose that linking different taphonomic processes to resource scarcity and intensification can provide powerful adjunctive information. However, because different processing outcomes may be associated with different kinds of resource intensification in response to different kinds of scarcity, we need to strengthen the validity of purported taphonomic indicators with more rigorous independent studies.  相似文献

Numerous studies in the US Southwest suggest that prehistoric artiodactyl populations in areas of dense human settlement experienced population reductions which substantially reduced their availability to human hunters. Although most assemblages from villages in this region are dominated by lagomorphs, some settlements maintained greater access to artiodactyls. Factors influencing this variability include both local settlement history and settlement location relative to productive source areas for large game. In our study areas, source–sink dynamics likely contributed to the long-term resilience of hunted artiodactyl populations and allowed villagers continued access to animals moving in from source areas despite relatively rapid game depletion in heavily hunted areas immediately around villages.  相似文献

ABSTRACT

Developing modes of engagement in the construction of public heritage knowledge emphasize participatory media and active collaboration with citizens. The City of Edmonton created the first historian laureate position in Canada in 2010, and related programs are still rare. This article considers the interaction of narrative content with social and technological contexts of production, viewing the role of the historian laureate as amateur historian and professional storyteller. The historian laureate operates primarily in accessible contexts of leisure, mediated in part through digital technologies, and can respond relatively directly to community interests as a heritage coordinator rather than expert. Rather than representing oppositional or disruptive power to official heritage discourses, the project enables the production of ‘small heritages’ through a series of story episodes. These stories focus on events, people, places and artifacts that typically fall outside the meta-narratives and monuments of a city’s heritage landscape. The historian laureate, embodying or articulating local experience in ways amenable to leisure activity, demonstrates capacities to produce largely indeterminate, diverse and porous ideas of place and histories as part of a bottom-up social generation of knowledge.  相似文献

This paper charts the attempts to construct an international map of the world using a standard projection and common conventions and symbols. The first part of the paper discusses the original incarnation of this idea, the International (1:1 Million) Map of the World (IMW), initially proposed by the German geographer Albrecht Penck in the early 1890s. The IMW was designed to challenge the idea that cartography was an inherently national science undertaken by, and for, specific nation states. Despite endless negotiations, delays and compromises, two world wars and the withdrawal of American support, the IMW project continued through the early and middle decades of the twentieth century, initially at the British Ordnance Survey and subsequently at the United Nations, only to fizzle out in the 1970s. The second part of the paper examines the Global Mapping Project (GMP), the latest manifestation of the same idea. Global Map, the first version of which was released in 2000, is an attempt to construct a single world map for the digital age. Like the IMW before it, Global Map is designed to facilitate a common, trans-national understanding of global problems. However, the technical, institutional and application challenges facing the GMP are different from those that confronted the IMW. Whereas the primary purpose of the IMW was never consistently defined, Global Map has a clearer environmental and educational objective. But if Global Map is to become an effective tool for sustainable environmental management and development, its advocates will need to learn the lessons of the IMW's failure and secure renewed international commitment to the value of international mapping.  相似文献

Hotels and hotel chains are responding to globalization and increased competition through new marketing initiatives, employment practices, and restructuring decisions that are intensifying the work of cleaners. In this paper, we report on how such work intensification at two hotels in Montréal, Canada, is changing the nature of cleaners’ jobs. Specifically, we found that the numbers of operations to be completed, the numbers and weights of items to be cleaned, and the effort involved have all increased. “Flexible” employment relationships and outsourcing have also worsened cleaners’ workloads. In response to our research, the labour union representing cleaners has negotiated a lower number of room assignments per cleaner, as well as an improved way of taking into account the variability of work when determining the quota of rooms to be cleaned. Despite this, new marketing strategies continue to intensify work. We conclude that standards and regulation on a governmental level are a necessary complement to union actions.  相似文献

Trepanations have been described from various locations around the world leading to a suggestion that this is a cultural practice that has widely diffused from one or two centres ( 1 ). In the UAE the earliest trepanations date to the Neolithic, significantly earlier than trepanations in surrounding areas. The discovery of at least two crania in Oman, dating apparently to the early third millennium and resembling in technique and placement trepanations from north India may be evidence of the diffusion of a therapeutic practice from the Gulf to the subcontinent. However, the lack of any trepanation among the numerous contemporary skeletons from Bahrain suggests that any diffusion has distinct limits and that, as anthropological work from the South Pacific ( 2 ) indicates, practices like trepanation are often heavily embedded in broader, culturally located explanatory models.  相似文献
