The rock art in Altamira Cave was the first ensemble of Palaeolithic parietal art to be identified scientifically (Sautuola, 1880). Due to the great thematic, technical and stylistic variety of the art in the cave, which constitutes one of the most complete Palaeolithic art ensembles, Altamira was listed as World Heritage by UNESCO in 1985. Uranium-series dating has recently been applied to figures on the decorated ceiling in the cave. Several motifs are partly covered by thin layers of calcite precipitates, whose formation process is datable by this method. The results provide the date when the calcite formed, which gives a minimum age for the underlying depictions. These results confirm that the parietal art at Altamira was produced during a prolonged period of time, at least 20,000 years (between 35,000 and 15,200 years ago), and that part of the ensemble corresponds to the Aurignacian period.  相似文献

In the year 1900, Sweden probably had the oldest population in the contemporary world. It was also the first nation to implement a universal pension system in 1913. The universal character in early social legislation has certainly been decisive for the development of the Swedish welfare state. This alternative has not been self-evident. Why did the reforms turn universal, when the continental model, the Bismarck social security system, was exclusively directed at industrial workers? Research has concentrated on demographic factors and growing demands for social security, or on the fact that Sweden was still a predominantly rural society with about 2,400 local authorities. This article examines the development of social legislation in the light of local government expenditures and incomes, and suggests an overlooked possibility: the formulation of the first universal national social security reform was a redistributional response to uneven distribution of incomes and general expenditures among the rural districts in Sweden.  相似文献

Sustainable development as a process towards sustainability requires collaboration among societal actors and stakeholders at multiple levels. A key issue is to provide them with that they have comprehensive and transparent knowledge base representing the state and trends of different dimensions of sustainability. This study addresses the need to analyse and present data of sustainability as a foundation for the sustainable development process within municipalities, and among them. As a case study, we focus on 18 municipalities in the crisis-struck Bergslagen region in Sweden and compare them with 101 surrounding municipalities. Data from 2001 and 2006 on 15 indicators representing ecological, economic and social sustainability criteria were transformed to a common scale through normalization around the median, and summarized. Bergslagen region municipalities performed poorer than the surrounding ones for all dimensions in 2006. The change from 2001 to 2006 was positive for economic and social criteria, while the ecological dimension developed negatively in all municipalities. We stress the need for municipalities to collaborate with each other and other actors both at municipal and regional levels, and to use sustainability indicators as a base for informed planning processes. We propose visualization of indicators using maps to support decision-making and social learning.  相似文献

Osteoporosis is a prevalent condition in Norway, as evidenced by the fact that this country has the highest reported incidences of hip and distal forearm fractures. Because recent studies suggest a higher bone density in rural populations compared with urban ones, increased physical activity is believed to be an important factor in reducing fracture incidence. In the present investigation, 185 femoral necks from the Schreiner Collection in Oslo were measured by means of a bone‐mass scanner. The bones, anthropological specimens ranging from the Stone Age to the Middle Ages, were separated into three groups: prehistoric (n = 36), Viking Age (n = 38) and medieval (n = 111). The medieval group was further separated into urban, rural and monastic populations. The examination showed that: (a) there was no significant difference at a 5% level in average bone mineral density (BMD) between the male and female material; (b) there was no significant difference in average BMD among the prehistoric, Viking Age, and medieval periods (P = 0.151); (c) there was no significant difference in average BMD between the rural and urban medieval material; (d) there was a significant difference in average BMD only between the monastic and the rural medieval material; (e) only the medieval material showed a significantly higher average BMD than that of today (P = 0.001). These findings may indicate that factors in addition to physical activity are important for normal BMD maintenance. Copyright © 2006 John Wiley & Sons, Ltd.  相似文献

In this article, I discuss the role of the three Scandinavian central banks in the establishment of the Bank for International Settlements (BIS) in 1930, and in the international lender of last resort operation towards Austria in 1931. I argue that small central banks were reluctant supporters in the establishment of the BIS and free riders in the Austrian crisis, even though there were marked differences in their attitude to international cooperation. These results run counter to the views of those International Political Economy (IPE) theorists who argue that small states should be in favour of international cooperation. On the other hand, the evidence seems to confirm Kindleberger's hypothesis that small countries were free riding during the international financial crisis of 1931, and that therefore there is a need for some coordinating mechanism, or a hegemon, in such crises.  相似文献

Despite vibrant paradigmatic shifts in archaeological thought, Norwegian heritage legislation remains unchanged since the 1970s and is anchored in a traditional identity ideology assuming continuous links between contemporary populations and ancient societies. In the context of current and expected major demographic changes as a result of global migration, policy-makers and developers of alternative frameworks face the challenge of epistemic standstill and recycling of ideas. This article examines and seeks insights into causes for the current status, focusing on tensions between paradigms of value and between various levels of heritage management in and around Oslo, one of the fastest growing urban areas in Europe. Combining the discourse theoretical concept of nodal points with the method of qualitative coding analysis, we study responses by heritage management to perceived challenges of globalisation and demographic changes in all available official white papers produced after the year 2000. By reflecting on present narratives, our discussion relates to struggles over defining ‘Norwegianness’ and criticism of such notions. The identification of four levels of tension allows us to centre attention on key issues of importance to the societal aim of including and engaging an increasingly heterogeneous population, and to argue for a bottom-up and recursive approach.  相似文献

Although the productive fishing grounds had long attracted the Crown and the Church to northern Sweden, it was not until the sixteenth century that the judicial and fiscal powers of the Swedish Crown were exercised in full. Records show that the regular fishing in interior lakes formed a prominent enterprise among coastal farmer communities. This paper examines the social and economic context of farmers engaged in interior fishing with respect to the internal organization of village communities, principles of private and collective ownership, land-use strategies and inter-community relations. There are no a-priori assumptions about the coastal population being “Swedish”. Instead of applying ethnonyms, the terms “farmer” and “coastal” are used throughout the paper. The main area of investigation includes the coastal area of northernmost Sweden and the western parts of Finnish Lapland. The study shows that interior lakes fitted into village resource areas, long sanctioned by usage, and that usufruct belonged to village members collectively. A large part of the fishing lakes are situated in interior Sámi territory. Fishermen were internalizing Sámi place names, implying close relations between the groups. Archeological investigations point to subsistence strategies including systemic interior lake fishing being established before AD 1200. The authors propose that coastal and interior communities should be perceived as two economic strategies representing indigenous and pre-colonial land-use schemes.  相似文献
