This paper presents and interprets two data sets from Vestfold, Southeast Norway: the pollen record is from a small lake basin, isolated from the sea in Mid Mesolithic (8100–6400 cal BC), and with a record of sediment deposition up to recent time. Charred plant remains from six settlement sites ranging in date from the Late Neolithic (2400–1800 cal BC) to the Merovingian Period (cal AD 570–800). Soil from archaeological contexts that was recovered from several prehistoric settlement features (two- and three-aisled houses, a rock shelter and a pit) has also been investigated. The number and concentrations of identifiable charred macro remains are low from all features except one, but the records contribute to the interpretation of agriculture and wild plant use. Carbonised cereals dated to the Late Neolithic/Early Bronze Age are reported from a two-aisled house. Naked barley was the main cereal identified and a few weed seeds were found with the cereal grains. In a rock shelter nearby, cereals and seeds of flax were found, demonstrating cultivation in the Late Bronze Age. Pollen of ribwort plantain recorded in lake deposits in Nordbytjern, 0·5?km to the southwest, also indicates agricultural activity in the southern part of Vestfold during the Late Bronze Age. Archaeobotanical samples from Early Iron Age houses contained low concentrations of carbonised cereal remains, mainly hulled barley, but also wheat and oat. Seeds/fruits of weeds, plants of moist/wet habitats and grasses increase in abundance from the end of Roman Period. The high concentration of hulled barley found in a pit at the site of Ringdal 13 confirms that hulled barley was a cereal used in the Iron Age. Throughout the Iron Age, cereal pollen has a continuous curve in the Nordbytjern pollen diagram, demonstrating the significance of cereal cultivation in Vestfold. Flax was also cultivated in the vicinity of and probably processed in Nordbytjern. Large numbers of rush seeds and sedge nutlets indicate a possible involvement in basketry and cordage making and/or as animal fodder.  相似文献

Two Norwegian researchers examine the forces alternatively driving and hindering offshore hydrocarbon development in the Russian sector of the Barents Sea. The paper describes exploration activities beginning during the Soviet period and extending to the present, the status of the major development projects financed in part with foreign capital, and conflicting regional and central government interests involved in such development. Coverage includes the emergence of Rosshelf, an oil/gas conglomerate formed to facilitate defense conversion activities of major naval shipyards. Critical to analysis of the projects' potential is assessment of alternative gas supplies and energy development strategies.

Higher values in pollen diagrams from Hardangervidda of, e. g. Plantago lanceolata and Artemisia, above their altitudinal limits are caused by endo‐and epizoochory of pollen and seeds. The continuous traffic across the northern part of the mountain plateau is dated back to A.D. 550.  相似文献

The former agricultural use of two sites located in the boreal forest of eastern Norway is investigated through pollen analysis. A peat profile was taken from the vicinity in each of two clearance cairn fields where several cairns were analysed for pollen. The pollen samples from the peat profiles give an environmental context for the pollen samples from the clearance cairns, and this combination of samples assists in evaluating the management practices that were in place on the cairn fields during different time periods. In both study areas cultivation layers under the clearance cairns are dated to the Late Roman Iron Age (cal. AD 200–400), while the oldest clearance cairns are dated to the Migration period (cal. AD 400–570), and a second phase of clearance cairn establishment is dated to the Medieval period (cal. AD 1030–1537). Abandonment of the two cairn fields is dated to c. AD 1700. Pioneer trees were a feature on or around the clearance cairn fields during most of the Iron Age, whereas the cairn fields were more open in medieval times. The investigation suggests that cereal cultivation on the clearance cairn fields is difficult to detect in local peat deposits, and that caution is needed when interpreting lack of Cerealia pollen. Management practices on the cairn fields are discussed and a change in management practice is indicated in association with medieval intensification.  相似文献

There are roughly 70 secessionist movements around the world, and all of them advance arguments for why they deserve independence. These include restorative rights, remedial rights, primary rights, a history of conflict and functionality-based arguments. However, no one has conducted a comprehensive analysis to see how these arguments (or grievances) match reality. That is, are secessionists making the right arguments given their context? To answer this question, we utilise a data set of potential secessionist grievances to determine what normative arguments each secessionist movement ought to make given their setting. We conduct a content analysis of the normative appeals/grievances that have actually been made by specific secessionist movements since 2000. We then compare the predicted grievances against the actual grievances and summarise the patterns. The results matched our predictions where restorative rights, remedial rights and functionality-based arguments are concerned. Our analysis returned a positive and statistically significant relationship. However, we found no evidence that those making conflict-related arguments were more likely to exist in conflict settings. Interestingly, the findings for primary rights were the opposite of our expectations; it is the secessionists with the most political voice, not the least, that are the keenest to stress primary rights.  相似文献

The Thabeikkyin earthquake (moment magnitude scale of 6.8) occurred on November 11, 2012; its epicenter was located 25 km from Thabeikkyin Township, Mandalay Region, Myanmar. Many buildings were damaged severely during the earthquake. In this study, damage patterns of brick-nogging buildings were firstly developed, and damage grades were characterized to allow for easy classification of the damaged buildings. The damaged data of all building types in the surveyed areas were collected by classifying the four damage levels as no damage, slight damage, moderate damage, and heavy damage. To develop the damage patterns of brick-nogging buildings, damage categories were arranged into three damage grades (slight, moderate, and heavy damage). Secondly, a questionnaire survey was conducted to calculate the seismic intensities of the affected areas. Medvedev–Sponheuer–Karnik (MSK) seismic intensities for the surveyed areas were estimated by analyzing the questionnaire survey responses. Finally, fragility curves for brick-nogging buildings were constructed using the estimated seismic intensities from the survey responses combined with the damage levels. These fragility curves may be useful to assess damage to brick-nogging buildings and to predict the number of damaged buildings in future earthquakes.  相似文献

This paper assesses the prospects for Soviet gas exports to Western Europe, analyzing both supply (domestic) factors, such as gas production, consumption, and transportation, and demand (foreign) factors such as gas demand and market share. This is done using a network allocation model of the Soviet gas pipeline network (for 1985, 1990, and 1995) and a country-by-country analysis of the gas market in Western Europe. In general, the outlook for increased gas exports to Western Europe, at least to the turn of the century, is rather bleak. This is mainly due to a relatively slower rate of growth of gas demand in Western Europe than projected earlier, coupled with overcontracting of gas supplies, because the USSR has enormous gas reserves, ample production, and no major pipeline bottlenecks restricting export volumes. Its huge pipeline construction program allows both domestic consumption and exports to be comfortably accommodated  相似文献
