The purpose of this study was to identify reactive bacterial aDNA in archaeological human dental calculus. Dental calculus was collected from a middle/late Neolithic human skull from Hulbjerg passage grave, Langeland, Denmark and prepared for transmission electron microscopy (TEM) or gold-labeled antibody TEM. TEM showed calcified, as well as non-calcified bacteria. Immunogold labeling occurred over the cytoplasmic portions of the sectioned bacteria. The result demonstrated that it is possible to identify aDNA sequences from bacteria in archaeological material of considerable age by this technique. 相似文献

AbstractFor more than a decade, tourist destinations in Denmark have experienced decreasing market shares and numbers of international visitors in comparison with the early 1990s. Despite this stagnation, destination development initiatives and national tourism policies have continued largely unaltered, relying on traditional efforts like collective marketing and local visitor information services, while giving limited priority to innovation-oriented measures that could improve the international attractiveness of Danish destinations by renewing the tourist experiences available. The article argues (1) that important reasons for the slow adoption of new destination development strategies can be found in the domination of tourism-related policy networks by short-term sectoral and localist interests, and (2) that recent reforms of subnational and sectoral governance have only improved the prospects of introduction of more innovation-oriented destination development policies to a limited extent. 相似文献

Provincializing Urban Political Ecology: Towards a Situated UPE Through African Urbanism 总被引:4,自引:0,他引:4
Urban political ecology (UPE) has provided critical insights into the sociomaterial construction of urban environments, their unequal distribution of resources, and contestation over power and resources. Most of this work is rooted in Marxist urban geographical theory, which provides a useful but limited analysis. Such works typically begin with a historical‐materialist theory of power, then examine particular artifacts and infrastructure to provide a critique of society. We argue that there are multiple ways of expanding this framing, including through political ecology or wider currents of Marxism. Here, we demonstrate one possibility: starting from theory and empirics in the South, specifically, African urbanism. We show how African urbanism can inform UPE and the associated research methods, theory and practice to create a more situated UPE. We begin suggesting what a situated UPE might entail: starting with everyday practices, examining diffuse forms of power, and opening the scope for radical incrementalism. © 2013 The Author.

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

Abstract: Taking our reference point from the French cultural sociologist Pierre Bourdieu's idea of the Social field, in this paper we will seek to identify and discuss a number of characteristics which define the public library. As changes within the public library system are often instigated by external factors we will place special emphasis on an analysis of the status, which the library holds in society. On the basis of the above we will, while concluding, put forward our idea of strategies needed to make the public library visible in the 21st century. 相似文献

As a result of metal detector surveys over several years, a unique find of gold figurines and gold foil figures from the 6th century AD has come to light at a locality known as Guldhullet (‘the gold hole’). Geomagnetic surveys and a subsequent excavation in 2017 revealed a large number of ‘cooking pits’ close to the present‐day damp area where the finds were made. The pits are roughly contemporary with the gold finds, which suggests that the location was both a sacrificial site and an important communal meeting place. 相似文献

The perennial issue of the relations between science and technology and society is a backdrop to this study of material, symbolic and economic foundations of engineering science in Sweden. It analyzes three cases of institutional reform from the first half of the twentieth century that were essential to the formation of engineering research as a distinct and respected scientific field. Taking the intersection of institutional and linguistic analysis as a starting point, two intertwined processes are followed: the drawing of boundaries by different actors that delineated the new kind of research, and the struggle over resources for the institutions that could enable this research. The institutional reforms are placed in context, relating arguments by the proponents of engineering research to the politicians and university academics who were in control of various resources. It is suggested that an institutionalist perspective enunciated in terms of form and content is a productive interpretive possibility. 相似文献
