A total of 150 intricately carved bone slips were uncovered at the Loughcrew H passage tomb in Co. Meath, Ireland, during excavations between 1865 and 1943. Studies of the carvings identified La Tène motifs suggesting that the slips may have been Middle to Late Iron Age in date. Joseph Raftery even went so far as to argue that the megalithic tomb itself was an Iron Age construction. His theory has since been debunked, but absolute dates have not been forthcoming for either these finds or the tomb. The following Middle Iron Age results presented here are slightly earlier than the dates that had hitherto been anticipated and they help to shed light on the subsequent interactions with this tomb.  相似文献

This paper investigates how the overall impact of the European Cohesion Policy depends on the composition of the regional investment in Hard (infrastructure) and Soft (business and technical support) projects. The study employs a generalized propensity score (GPS) analysis in a multidimensional treatment context. In particular, the two dimensions considered are given by the Hard and Soft investments. The GPS estimation is based on a set of relevant idiosyncratic features of the regions. The second step estimates a dose–response function in a two-dimensional setting. The results confirm the existence of nonlinearities in the effect of different amounts of funds, but more importantly, show a degree of complementarity between Hard and Soft investment and that for policymakers, it is crucial to exploit such features to achieve more significant impact. The EU's more developed regions could have achieved a doubled GDP p.c. growth rate by pursuing a policy mix where Hard investments are reduced in favor of Soft investments. This improvement is comparable to the one obtained by at least doubling the available resources. The findings add to the evidence collected on the impact of the Cohesion Policy, suggesting a shift of the debate from the quantity to the quality of the expenditure pursued under the umbrella of territorial policies.  相似文献

Weimar Germany's economic plight has oftentimes been blamed on reparations in simplistic fashion. Alternative interpretations ignored reparations entirely, instead emphasizing gold standard constraints or wage increases in excess of productivity growth. This paper argues for a strong but subtle link between Germany's slump and these policies. Based on sovereign debt theory, it provides an incentive-based interpretation of the transfer problem, the compensation of reparations by counteracting capital inflows. I argue that the German transfer problem resulted from transfer protection under the Dawes Plan, which gave commercial credits seniority over reparations. This gave Germany a strategic incentive to drive out reparations through foreign borrowing. The Young Plan of 1929 implied a reversal of this seniority scheme, causing a sudden stop in the balance of payments that lasted to the late 1930s. The Young Plan could only have worked in the absence of an international recession; attempts to salvage it in 1931 were necessarily futile.  相似文献

This paper presents a geochemical analysis of fragments of bituminous amalgam from H3, As‐Sabiyah (Kuwait), and RJ‐2, Ra's al‐Jinz (Oman). The fragments bear barnacles on one side and reed impressions on the other, and are thought to have been part of the coating of reed‐bundle boats. The material from H3 dates to between 5300–4900 BC, while that of RJ‐2 dates to 2500–2100 BC. Samples from both sites were geochemically compared to archaeological and ethnographic material from Kosak Shamali (northern Syria, c.5000–4400 BC), RH‐5 (Oman, 4400–3500 BC) and Baghdad (central Iraq, 1900 AD). The composition of the bituminous amalgams was studied in detail. Rock‐Eval Pyrolysis gave a measure of Total Organic Carbon in the samples, and allowed an initial comparison of the data sets using various parameters. Examination of the proportions of soluble and insoluble organic matter allowed an assessment of the quantity of vegetal matter added to the bitumen to make the bituminous amalgam. The composition of the Ra's al‐Jinz material was studied using X‐Ray Diffraction analysis and thin‐section petrography, in order to assess the proportions of various minerals in the bituminous amalgams. It was concluded that the recipe for the bituminous mixture used to coat reed‐bundle and wooden boats did not differ significantly from that commonly used to make ‘mortar’ for architectural purposes in Mesopotamia. Traces of animal fats or fish oils were not found in the analysed Ra's al‐Jinz material, in contrast to previous hypotheses regarding the composition of the mixture. Comparison of the gross composition of extractable organic matter (the constituents of pure bitumen, soluble in chloroform or dichloromethane) showed the progressive effects of weathering on the samples. The isotopic composition of the bituminous material from H3 and the other sites was then compared to that of bitumen seeps and crude oils from Mesopotamia, Iran and Oman. The most significant result is that the material from As‐Sabiyah originated in Kuwait, at a surface seep at Burgan, while the material from Ra's al‐Jinz had a source in northern Mesopotamia.  相似文献

In later pre‐Columbian prehistory (post AD 1000), the adaptation and intensification of maize agriculture and its correlate of aggregate village settlement (i.e. Mississippianization) is temporally and geographically variable. In the Midwest, consequential to the florescence of the major ceremonial centre of Cahokia (AD 1050–1300), the Mississippi River Valley alluvial plain in Illinois, known as the American Bottom, became a core area of this subsistence‐settlement change. Much archaeological research has traced aspects of this transition in the Lower and Middle Illinois River Valley, but little is known outside of these areas. A skeletal sample from the remote hinterland area of the Upper Mississippi River in west‐central Illinois was examined for arguable paleopathological correlates of sedentism (treponemal disease) and Mississippianization (tuberculosis). The Schroeder Mounds (AD 900–1100) adult skeletal sample (N = 53) exhibited a high frequency of treponemal disease (13.2–15.1%). This result is consistent with paleopathological literature linking a 9+ % pre‐Columbian North American prevalence with sedentism, challenging archaeologically based inferences that the hinterland was occupied by mobile forager‐horticulturalists. A hallmark of Mississippianization is the presence of diagnostic cases of tuberculosis. No cases were observed in the Schroeder sample, suggesting a pre‐Mississippian subsistence‐settlement pattern.
