Problems of sampling carbonized plant material are discussed. Firstly, the problem of actually selecting a sample in the laboratory is considered, and some experiments which investigate various procedures are described. Secondly, the statistical aspects of determining optimal sample sizes are considered. Formulae are given for calculating optimal sample sizes and confidence intervals. Upper bounds, which are independent of the total population size, are provided for the sample size required to achieve any desired accuracy. 相似文献

The historical Norberg mining district in central Sweden with its shallow, easily accessible iron ores figures prominently in the earliest documents from the 14th century concerning mining or metallurgy. This 1000-km2 district is considered to be one of the first areas in Sweden exploited for iron ores and, in fact, Europe’s oldest known blast furnace, Lapphyttan, is located in the Norberg district about 10 km from the mines in the village of Norberg (Norbergsby). Earlier archaeological excavations suggest the furnace was in operation as early as the 11th or 12th century (870 and 930 14C yr BP), and a number of other sites in the district have been dated to the 13th–15th centuries. Here, we have analyzed two lake sediment records (Kalven and Noren) from the village of Norberg and a peat record from Lapphyttan. The Lapphyttan peat record was radiocarbon dated, whereas the sediment from Kalven is annually laminated, which provides a fairly precise chronology. Our pollen data indicate that land use in the area began gradually as forest grazing by at least c. AD 1050, with indications of more widespread forest disturbance and cultivation from c. 1180 at Lapphyttan and 1250 at Kalven. Based on 206Pb/207Pb isotope ratios in Kalven’s varved sediment record, there is an indication of mining or metallurgy in the area c. 960, but likely not in immediate connection to our sites. Evidence of mining and metallurgy increases gradually from c. 1180 when there is a decline in 206Pb/207Pb ratios and an increase in charcoal particles at Lapphyttan, followed by increasing inputs of lithogenic elements in Noren’s sediment record indicating soil disturbance, which we attribute to the onset of mining the iron ore bodies surrounding Noren. From AD 1295 onwards evidence of mining and metallurgy are ubiquitous, and activities accelerate especially during the late 15th century; the maximum influence of Bergslagen ore lead (i.e., the minimum in 206Pb/207Pb isotope ratios) in both Kalven and Noren occurs c. 1490–1500, when also varve properties change in Kalven and in Noren sharp increases occur in the concentrations of a range of other ore-related metals (e.g., arsenic, cadmium, copper, iron, lead, mercury and zinc). From the 15th century onwards mining and metallurgy are the dominant feature of the sediment records. 相似文献

In this article it is argued that between 1870 and 1910 the Swedish social liberal state used economic grants as a political tool in order to govern parts of the sector of social movements. State grants given to non-formal education, folk high schools, organizations that held lectures for the working class, and organizations that set up libraries are the point of departure for the analysis. The specific governing measure consisted of making the sector flourish in a ‘state of autonomy’, a state in which their conduct was influenced by the need to fulfil certain demands in order to receive funding. The requirements included, for instance, that the organizations were governed by a specific form, that they were in liaison with the local government, and that they did not wander outside the ideological demarcations set up by the government. In conclusion, the article shows how the state tried to govern the conduct of non-formal education. 相似文献

AbstractBased on an overview of feminist and gender research over two decades, this article reflects on feminist geographies in Norway within a wider political and social context. We identify eight broad, partly overlapping themes of feminist geography: rurality; development policies and practices; entrepreneurship and economic change; migration and mobility; children and youth; sexuality and health; landscape and place; and emotions and autobiography. We find that much of the research has been collaborative, interdisciplinary, multicultural, and transnational. Feminist geographies in Norway are characterized by increasing emphasis on multiple realities and situatedness, and focus on rights and power relations among men and women in all spheres of society, including academia. Yet the gender dimension has tended to focus on geographies of women, with few studies of masculinity. Inspired in part through feminist critiques of research practices in social sciences, a recent development has been autobiographical approaches examining the significance of personal lives and emotions for the research process. We conclude that feminist geographies in Norway are diverse, empirically and contextually informed, and have become embedded within several fields of human geography. 相似文献

ABSTRACTThis viewpoints paper reflects upon the journey youth geographies have travelled over the last 20 years and highlights some thoughts on where directions for new research might be best placed in the coming decades. In particular, the paper draws attention to the growing numbers of youth in the Global South and especially in the African continent where youth populations are set to continue to rise. The paper identifies some of the potential challenges faced by the majority of youth in coming years in particular the need to decolonise thinking around youth geographies while also considering the importance of economic, social and political contexts in shaping debates. The paper charts some potential new directions while also suggesting that youth’s own perspectives need to receive greater prominence in theory and outcomes. 相似文献
