Direct identification of fodder provisioning in individual animals is a previously unexplored area that has important implications for determining animal husbandry strategies in prehistory. In this study, foddering practices are examined in modern domestic and wild caprines from Mongolia (Baga Gazar'in Chuluu) through carbon and nitrogen analyses of bulk sampled dentin collagen in molar teeth. Foddered caprines display significantly different δ13C values compared to non-provisioned caprines. This pattern reflects the consumption of C4 plants year-round by provisioned caprines while non-provisioned caprines ingest C4 plants only during the summer months. Provisioned caprines also display significantly different nitrogen isotopic values relative to non-provisioned animals. The difference in nitrogen isotopes between wild and foddered animals may be due to increased access in quality graze through foddering by domestic caprines, which results in improved nutrition and extended lactation periods, or enriched δ15N of fodder plants relative to background flora. Differences in tooth wear between sampled wild and foddered animals may also contribute to the observed δ15N differences.  相似文献

X-ray microtomographic imaging of charcoal   总被引:5,自引:0,他引:5  
We assess the potential of X-ray microtomography as a tool for the non-destructive, three-dimensional examination of the internal structure of charcoal. Microtomographic analysis of a series of charcoals produced by the experimental pyrolysis of pine wood at temperatures from 300 and 600 °C in nitrogen only and in nitrogen mixed with 2% oxygen indicates that, despite substantial shrinkage, observed porosity, pore size and pore connectivity are all increased by pyrolysis and also by chemical oxidation. Analysis of a number of altered and unaltered archaeological and geological charcoals has demonstrated the capacity of the technique to identify and map the distribution of authigenic mineral contamination within charcoal fragments. The results are of significance to radiocarbon dating in that they provide insights into the mechanisms by which charcoal can be contaminated by extraneous carbon in the natural environment.  相似文献

Popular representations of the fashionably dressed female body between 1914 and 1918 were highly contradictory and, as this essay will show, were sharply delineated in Home Chat, one of a growing number of relatively new women's magazines which addressed the needs of an expanding skilled working-class and lower-middle-class female readership. Aiming to provide women with practical advice about all aspects of their daily lives, from the traditional concerns of fashion and beauty, marriage and children, to the more contentious issue of women's aspirations beyond the home, Home Chat was uniquely placed to reflect shifting gender and class relations.  相似文献

The role of the private sector in international development is growing, supported by new and evolving official programmes, financing, partnerships and narratives. This article examines the place of the private sector in ‘community development’ in the global South. It situates corporate community development (CCD) conceptually in long‐standing debates within critical development studies to consider the distinct roles that corporations are playing and how they are responding to the challenges and contradictions entailed within ‘community development’. Drawing on field‐based research across three different contexts and sectors for CCD in Fiji, Papua New Guinea and South Africa, the article suggests that caution is required in assuming that corporations can succeed where governments, non‐governmental organizations (NGOs) and international development organizations have so often met with complex challenges and intractable difficulties. We argue that four specific problems confront CCD: (a) the problematic ways in which ‘communities’ are defined, delineated and constructed; (b) the disconnected nature of many CCD initiatives, and lack of alignment and integration with local and national development planning policies and processes; (c) top‐down governance, and the absence or erosion of participatory processes and empowerment objectives; (d) the tendency towards highly conservative development visions.  相似文献

Our investigations combine detailed identification and interpretation of plant remains and associated fauna and their mode of arrival in one of the rock-cut galleries, Cave 3, at the site of Mersa/Wadi Gawasis on Egypt’s Red Sea coast. The site served as a staging area and harbor from which Middle Kingdom pharaohs launched seafaring expeditions to the land of Punt in the early second millennium BC. Quantities of wood, including ship timbers, fastenings, debris related to ship dismantling and reworking, and charcoal were excavated and analyzed. Evidence of marine mollusk infestation (shipworm) was abundant in Cave 3, as were the remains of insect pests of stored foods. We also report on a unique find of a plaster “spill” that preserved the floor of Cave 3 as it was when people worked in the gallery ca. 3800 years ago. The plaster spill created a sealed deposit of plant and insect remains with a diagnostic ceramic fragment, allowing us to securely associate insect remains and “hollow” spikelets of emmer wheat (Triticum dicoccum) recovered from the gallery. An impression of the beetle Trachyderma hispida and its associated exoskeleton fragments provide new evidence of this species as a potential pest not yet reported from an archaeological grain storage site in Egypt. The finding of Tenebroides mauritanicus from the same deposit is the earliest known association of this pest with stored grains. These unique finds shed new light on the risks associated with preserving food supplies, combating pest infestation, and dealing with marine organisms on land and at sea in the pharaonic harbor.  相似文献

This paper draws on empirical research in South Africa to explore questions about the exclusionary nature of citizenship, the problems and possibilities of participatory citizenship and its potential reconceptualisation through the lens of gender. The paper examines some of the major debates and policies in South Africa around issues of citizenship, participation and gender and explores why the discursive accommodation of gender equity by the South African government is not fully realised in its attempts to construct substantive and participatory citizenship. It explores some of the emergent spaces of radical citizenship that marginalized groups and black women, in particular, are shaping in response. Findings suggest that whilst there are possibilities for creating alternative, more radical citizenship spaces, these can also be problematic and exclusionary. The paper draws on recent feminist writing to examine the possibilities for rethinking citizenship as an ethical, non-instrumental social status, distinct from both political participation and economic independence. This reframing of citizenship moves beyond notions of ‘impasse’ or ‘hollowness’, challenges the public/private distinction that still frames many debates about citizenship and considers the emancipatory potential of gendered subjectivity. The paper argues that citizenship is shaped by differing social, political and cultural contexts and this brings into sharp focus the problematic assumption of the universal applicability of western concepts and theories.  相似文献
