The applicability of a post‐infrared infrared stimulated luminescence (pIRIR290) protocol and two different thermoluminescence (TL) protocols—a single aliquot regeneration (SAR) and a multiple aliquot additive dose (MAAD)—was tested on six polymineral fine‐grain (4–11 μm) samples extracted from the wall remains of a Roman lime kiln and a Roman roof tile. These remains had been excavated close to Bergisch Gladbach, which was at that time part of Germania magna. For the pIRIR290 measurements, no dependence of De on first‐stimulation temperature was detectable, and the standard first stimulation temperature at 50°C was adopted. Fading tests and dose‐recovery tests were made for all samples. Background subtracted glow curves were recorded up to 480°C for TL after a preheat of 220°C for 120 s. A‐values were determined for all TL and pIRIR measurements. The results for all three protocols were fairly consistent, and TL and pIRIR290 protocols are shown to be suitable to estimate reliable equivalent doses for the fired kiln walls. The resulting ages are in agreement with the expected time range—Roman Iron Age—and with independent age control provided by radiocarbon ages of animal bones and charcoal from the firing chamber.  相似文献

This study investigates the diet of the Roman and Late Roman population of Leptiminus on the Mediterranean coast of Tunisia. Stable carbon and nitrogen isotope analysis of human bone collagen and carbonate samples obtained from individuals buried in four cemeteries at Leptiminus was conducted in order to reconstruct the diet of the population, investigate the relative importance of marine vs. terrestrial resources, explore sex-, age-, and status-based variations in diet, examine temporal changes in the types of foods consumed, and compare the diet at Leptiminus with that of other Roman populations. The results of this study indicate that the residents of Leptiminus consumed a diet that was heavily reliant on terrestrial plant resources with the addition of a significant amount of marine resources. There were no significant sex differences in isotope values. In contrast, distinct dietary differences were seen between the adults and children. Nitrogen isotope values suggest that weaning began before the age of two and was completed by about 3 years of age, a finding consistent with previous isotopic studies of Roman samples. A temporal shift in diet is suggested by the nitrogen isotope values measured in samples from the most recent cemetery. A comparison of the data from Leptiminus with that derived from other Roman sites indicates that regional variability in diet existed within the Empire.  相似文献

This paper addresses two main debates: the recent geographical literature on trade union strategy and structure, and contemporary accounts of European labour market governance. Geographers have begun to take notice of organized labour just as it has faced a series of unprecedented challenges, which are partly derived from ongoing changes in the organization of production. In interpreting these debates I focus on the process of scaling – the ways in which the politics of labour market governance are constituted in, and are at the same time constitutive of, one geographical scale or another. These issues are explored through two key recent developments: the changing status of the European Trade Union Confederation, and the creation of European Works Councils. The ETUC and EWCs are particularly significant because they pose a challenge to existing arrangements, and potentially enable a re-configuration of the relation between capital and labour at different scales. I conclude that further exploration of European labour geography could re-connect the diversity of forms of organization of production with the scope and potential of trade union strategy; and that thinking in terms of scale is useful because it highlights the significance of both political and relational issues.  相似文献

Several funnel-shaped features of unknown function were discovered at excavations related to a new stretch of the highway E4 in middle Sweden during 2002–2003. These features could be sub classed into two categories: large funnel-shaped pits dated to 600–1100 AD (Vendel period – Viking Age) and small funnel-shaped pits dated to 240–540 AD (late Roman Iron Age – Migration period) respectively. Soil samples were analysed for diterpenoids derived from abietic acid (mainly retene, abietic acid, dehydroabietic acid and methyl dehydroabietate) by Gas Chromatography-Mass Spectrometry (GC-MS) in order to test the hypothesis that the features might be connected to pine tar manufacture. For comparison, samples from historically known pine tar and charcoal production features were analysed. The resinous fraction in the larger funnel-shaped features were very similar to those of the historical pine tar and charcoal production features, while the composition in the small funnel-shaped pits was dominated by retene and methyl dehydroabietate. The biomarker, methyl dehydroabietate, could be identified in several of the soil samples from the funnel-shaped pits. We suggest that both of these features have been used for pine tar production, which makes the smaller funnel-shaped features the oldest known tar production features in Europe.  相似文献

Methodological advancements in geoarchaeology and spatial and chronological modeling are opening new avenues to interpreting large coastal shell-bearing sites. We document the developmental histories of two such sites around Prince Rupert Harbour, Canada, using systematic percussion coring, intensive radiocarbon dating, and 3D surface mapping with Total Station and LiDAR. We also re-analyze a third site (Boardwalk/GbTo-31) excavated and radiocarbon dated in the 1960s, 1970s, and early 2000s using archival field notes, site maps, and stratigraphic profiles georectified using LiDAR. We map the natural landform beneath the sites and document the degree to which people physically modified landforms through the deposition of massive shell accumulations. We model site development through time and space and use accumulation rates and OxCal modeling to test for intentional deposition events. All three sites demonstrate complex and heterogeneous occupation histories. At each we identify instances of very rapid deposition that effectively terraced and extended parts of the natural landform to create places for constructing houses, though these episodes take place within longer histories of slower quotidian deposition. The anthropogenic modifications to the coastline in this area are the result of these mixed processes associated with long histories of occupation.  相似文献

罗马教廷在对待伪满洲国的问题上采取了两手策略,一方面极力在外交和法理层面上回避与伪满洲国之间的关系问题,另一方面又在事实上承认了伪满洲国的存在。吉林教区主教高德惠作为罗马教延的实际代表与伪满当局合作,协助当局推行殖民主义政策,其在本质上已经成为日本殖民主义者的帮凶。  相似文献

As organic materials, fish and its derivative products are perishable and break down rapidly and ultimately disappear. Unless they include bones or scales, the only means of identifying them in the archaeological record is through the identification of the chemical constituents that are left behind after decomposition. Fish flesh mainly consists of proteins and lipids. Since these molecules are unstable they degrade irreversibly after death or discard, losing a significant part of the original chemical elements, consequently hampering or complicating their identification. In this paper, two main types of fish products are considered: raw, salted or cooked fish, and fermented fish-based products. In the first case, the degradation of the native markers results from chemical post-depositional degradation, and eventually thermal degradation during cooking. In the second case, the biochemical processes involve bacteria that cause the rapid decomposition of fish as part of the process of forming fish sauces, such as Roman garum. To detect and identify fish products we combined experimental archaeology and organic analyses. The identification of the degradation products of cholesterol appeared to provide a strong indicator for detecting the presence of fish sauces. Analysis of samples taken from fish-salting vats located along the Atlantic coast (Marsa, Baelo Claudia, Troia, Kerlaz, and Etel) with samples taken from actual experimental garum sauces made from mackerel (Scomber scombrus), sardines (Sardina pilchardus), and/or oysters (Ostreidae), revealed the presence of common markers of fermented fish-based products. The application of the analytical methodology described here to structures involved in ancient fish sauce manufacture and storage has enabled investigation of the production of the sauces by searching directly for the fish markers on the inner sides of the containers. For the first time the addition of molluscs and fruits in the fish product has been identified as part of the process of manufacturing garum.  相似文献

The detection of the waterlogged remains of massive oak foundation piles in the river Meuse near the Dutch city of Cuijk led to the discovery of a unique Late Roman site. The piles, driven into the river‐bed, had protected vast layers of organic material containing all kind of artefacts against erosion by the river. Increased erosion during recent decades has uncovered much of the structure and artefacts, which have been meticulously recorded and collected by divers of the Dutch foundation Mergor in Mosam. Analysis of all data retrieved over the past 20 years has provided much information about the environment and life in Ceuclum, the Roman city of Cuijk.  相似文献

The census is the traditional source of population figures at various levels. Census figures however are technically outdated immediately they are released because planners require figures for the present and possibly for future dates. In an attempt to meet this demand different organisations and researchers produce population estimates and projections. These estimates however are usually at higher geographical levels and often do not meet the planning needs of administrators at lower geographical levels. This study extends a top‐down estimation method to an African country by estimating the mid‐2014 population at ward level in South Africa. The study used the 2011 South Africa Census to estimate current levels of fertility, mortality as well as current trends in net migration at a higher geographical level. Historical trends in fertility and mortality were based on the 1996 Census, 1997 and 1998 October Household Surveys as well as the 2007 Community Survey data. The results indicate that that 20 of the largest wards as at mid‐2014 were located in South Africa's metropolitan areas. Nineteen of the 20 largest wards are currently growing at a rate of over 4% per annum and if this trend continues, eighteen of these wards will double their current population size in less than 15 years.  相似文献

The paper examines the historical and present-day role of the Royal Naval Dockyard, a globally motivated waterfront development of recurrent local dominance in the affairs of a small island community. Its historical role as a bastion of imperial naval defence, the Gibraltar of the West, is reviewed from the Victorian era until 1945; and its recent and continuing revitalisation, as heritage for tourist-leisure adaptive reuse, is discussed and illustrated. Its relationship to naval/waterfront heritage-oriented innovation elsewhere is considered; and the risks of such developments for the identity and tourist-historic economy of this and possibly other (ex)colonial naval outposts are queried.  相似文献

This paper attempts to demonstrate four things: (1) There is no adequate documentary basis for Petrie's ‘Northern’ system of lengths. (2) We do not know of any system into which Anglo-Saxon lengths were organized. (3) The perch of 5.03 m is the only Anglo-Saxon unit of which the length is known. (4) There is insufficient evidence to support the view that the Drusian foot of 33.3 cm was widely used by the Germanic tribes in general or in Anglo-Saxon England in particular. Conversely the modern English foot of 30.48 cm has more to recommend it as Anglo-Saxon than has previously been recognized.  相似文献
