Recent archaeological studies of human diet have used stable nitrogen isotope ratios (δ15N) from human bone collagen to infer the relative importance of terrestrial plant and animal foods. This approach is based on widely observed enrichment of δ15N up the food chain, plants having distinctly lower values than the herbivores that consume them. Studies of early farming diets in Britain, Denmark and Germany have tended to detect relatively high δ15N values (e.g. c. +9‰), interpreted as evidence of a diet largely based on animal products, though archaeobotanical evidence for crop cultivation (e.g. carbonised cereal grain and chaff) is widespread. This paper investigates the impact of manuring on δ15N values in modern cereals, and of charring on these cereal values. The results from two long-term experiments demonstrate that manuring significantly raises δ15N in cereal grain and chaff. Depending on manuring levels and frequency, it appears that human diets with a major component of such grain would conventionally be interpreted as indicating a largely animal-based diet or a mixed plant/animal diet. Moreover, preliminary analyses of experimentally charred grain and chaff from manured and unmanured conditions are promising for the extraction of reliable ancient δ15N values from archaeobotanical cereal remains. The wider implications of these results, and the need for further work, are discussed. 相似文献

Geoarchaeology represents crossdisciplinary research focused on environmental issues and human activities, and directed primarily to social scientists. Site micro-studies are central to the enterprise, emphasizing cultural sediments and the taphonomic record of site formation, preservation, or destruction. But when expanded to include off-site investigation and watershed studies, geoarchaeology can go well beyond stratigraphy and context, to address human impacts on the environment or long-term sustainability. This paper articulates a research agenda to evaluate the largely anecdotal premise that the island of Cyprus has been degraded by millennia of improvident land use. First, it outlines Holocene settlement, land use and forest histories, as a differentiated model against which to apply specific types of investigation, and in conjunction with other archaeological sciences. Second, it applies Quaternary-style watershed study to confront commonplace misunderstandings about possible degradation, to show that most of the slope and stream deposits on Cyprus are of Pleistocene age. Third, it switches to examples of site micro-geoarchaeology to illustrate the possibilities of understanding detailed change. The purpose is heuristic, in the absence of many more site and off-site studies that incorporate bioarchaeology. Provisional inferences suggest that environmental damage may be limited, that even with heavy land-use stress, climatic triggers were critical to inaugurate change, and that the system may be more resilient than anticipated. Such caveats may encourage greater attention to environmental research design in ongoing and future excavation projects. 相似文献

This article focuses on two Ottoman silk flags and discusses not only their original contexts of production but also traces their biographies until their reception as booty items and their further use after the Siege of Vienna in 1683. Banners and standards were symbolically charged signs used for military organisation. The higher the rank of a flag, the more coveted it was as booty. It was not so much their material value, which was in fact negligible, but rather their symbolic worth that made them so desirable. In their new context in the hands of the enemy they could be used for propaganda purposes, as indeed they were during and after the second siege of Vienna in 1683. This article investigates the trajectories of two flags captured at the siege and a year after its end and explores the intentions behind their use for propaganda purposes. It thus attempts to untangle the political rivalries, imperial vanities and cultural misunderstandings underlying their complex biographies. 相似文献

Classical diffusion research, both in geography and sociology, received considerable criticism in the 1970s and 1980s, but after that the diffusion debate has faded away. At the same time, one of the earliest contributors to diffusion research, Gabriel Tarde, is now attracting the attention of both geographers and sociologists. Drawing on earlier experiences with agricultural extension and the Green Revolution, this Tarde‐inspired article aims to revitalize the diffusion debate through an ethnographic case study of extension practices in Hambantota District, Sri Lanka. The study is based on field material collected between 2009 and 2011, which includes semi‐structured interviews with representatives from various spread agencies – government agricultural instructors, NGOs, social enterprises, and the inorganic industry – as well as with farmers and other key informants. Following the recent work of Nigel Thrift, it is argued that such an approach to the study of innovation diffusion can be a way of uncovering “the political economy of propensity”. The article suggests that a return to Tarde should not lead researchers back into naïve diffusionism, or towards a position that blames traditionalist farmers for non‐diffusion. Non‐human actors can also exhibit resistance and sociality: innovations travel through a landscape which is both human and non‐human, and the spread of organic farming practices is configured by both bonds of trust among farmers and bonds of chemicals in the soil. Furthermore, it contends that future research may interrogate the ways in which the very medium of diffusion is being reconfigured, following actors' institutionalization of innovation diffusion methods. 相似文献

The eruption of Eyjafjallajökull in Iceland in 2010 caused havoc to global air traffic. This article examines that event by looking at theories of risk and culture. We demonstrate the fragility of today's mobilities, which depend on unpredictable nature as well as complex technological systems. A new type of risk was revealed by the eruption, which has since become a feature of cultural risk portfolios in contemporary society. 相似文献
