This paper presents the results of stable isotope (carbon and nitrogen) analysis of human and faunal remains from the site of Aktoprakl?k, one of the earliest farming sites in the Eastern Marmara region of Northwest Anatolia. Excavations at this site have shown that occupation occurs from the middle of the 7th millennium BC through to the middle of the 6th millennium BC. The earliest Neolithic activity at this location occurs at the settlement site of Aktoprakl?k C. Since 2004 a number of Neolithic and Early Chalcolithic burials have been recovered from the settlement areas and an Early Chalcolithic cemetery (Aktoprakl?k B and A respectively). To date a total of 60 individuals have been recovered from Aktoprakl?k, 23 of which (20 adults [10 males, 8 females and 2 indet adults] and 3 children below ca. 12 years of age) form the basis of the current isotope study. In addition, 14 faunal samples from cattle, pig, sheep/goat and fallow deer are included in the analysis in order to facilitate a consideration of trophic level shifts and to interpret the 13C data. The data represents the first isotopic study of a farming community from this region of Anatolia. This region is important to our understanding of the north-westwards transmission of farming into Europe from the Near East, and as such Aktoprakl?k represents a key site for studying the diet of farmers at the transition to agriculture. The close clustering of isotope values overall indicates homogeneity in subsistence practices for this farming population. Interestingly, the isotope values indicate a general focus on C3 terrestrial resources at Aktoprakl?k, despite the close proximity of both freshwater and marine environments where alternative resources could have been procured.  相似文献

In this paper the results of use-wear analysis of an Amudian lithic assemblage recently discovered at Qesem Cave, Israel, are presented. Although very old, this assemblage maintains well-preserved traces of use that indicate that butchering activities and plants collecting were carried out at the site. Cut marks on faunal remains confirm the observations obtained by use-wear analysis.  相似文献

In recent years, following the lead of the US, several OECD countries have introduced 'workfare' policies that link receipt of unemployment and related social benefits to compulsory participation on state-administered work and training schemes. The UK's New Deal (Welfare-to-Work) for Young People is one of the largest and most developed of these workfare programmes. Official evaluations of the UK's New Deal for Young People claim that it has been a national success, but overlook local variations in its results. This paper uses the Government's own performance measures, data on local unemployment flows, numbers of New Deal participants recycled through the scheme as second starts, and interviews with both local policy managers and participants, to demonstrate that these local variations have been substantial. These different indicators suggest that the programme has been noticeably less effective in many inner urban and depressed industrial labour markets. In such areas the 'recycling and churning' of participants through the programme are more significant, and suggest that local labour market structures play a significant role in shaping policy outcomes. The paper argues that recent additions to the New Deal to improve job search and matching fail to address this local variation, and that a longer-term approach is required that seeks to improve not only the employability of individuals, but also the local employment opportunities open to them. One key implication is clear: that local labour market conditions can exert a significant influence on the outcomes of national workfare type policies, not only in terms of geographical variations in the problem to be solved, but also in shaping and constraining the local nature of policy outcomes.  相似文献

The Minnesota Population Center (MPC) has released linked datasets through its NAPP and IPUMS projects, making them readily accessible to researchers. Prior to the availability of complete count census microdata from the MPC, researchers applied various forms of record-linking software. This essay describes the techniques used in the MPC's linking program and briefly compares this technique with those used by other researchers. The key feature of the MPC linking method is the construction of cumulative name similarity scores, based on approximately 2.5 billion record comparisons; we also use support vector mechanics to classify potential links. This article explains modifications made for the final linked datasets and includes a discussion of the role of weighting variables when using linked data.  相似文献
