The measurement of the fineness of debased ancient silver coins has proven to be a very difficult issue, which has been studied for a long time. In this paper, this subject is analysed, and the various consequences of the silver surface enrichment (SSE) are discussed exploiting the most recent investigations. A new model is proposed for the complex object that is an ancient-debased silver coin, based on the silver profiles measured on some sectioned specimens. The model is applied to a sample of 43 coins, mainly Roman victoriati, Cisalpine and Illyrian drachms (from late III to I century B.C.). The coins are investigated in two different ways: neutron diffraction (ND) and specific gravity (SG). The results of the two measurements are combined via the proposed model to provide a more complete numismatic information of the original fineness of the monetary alloy. As a result, a relation between SSE thickness and SG is derived, which, for these coinages, allows to estimate the original alloy silver content from a simple SG measurement; the same method can be used to study other debased coinages, provided that all the procedure (ND and SG) is applied.  相似文献

We present the detailed analysis of a cervical vertebra from a cave bear, found at Pe?turina cave, Serbia, in a Mousterian archaeological level dated by radiocarbon at 43.5–44.6 kyr cal BP, and by ESR to between 93.5 and 102.5 kyr BP. Identified as a portion of the cranial articular facet, the fragment displays ten subparallel grooves. The microscopic study of these grooves and other surface modification present on the bone fragment, conducted with multifocus optical and confocal microscopes and complemented by a taphonomic analysis of the associated faunal assemblage, supports the hypothesis that the incisions were made by humans. Results are used to critically examine ambiguities implicit in the analysis and interpretation of early engravings, a category of material culture that has been playing a key role in the identification of early instances of symbolically mediated behavior.  相似文献

The article focuses on the Italian general election held on 4 March 2018, which was notable for the surprising results in southern Italy. These results will be analysed by looking at two dimensions of electoral behaviour: on one hand, participation and volatility, on the other the success of the protest parties, the Five Star Movement (M.5.S.) and the League. These features will be considered in relation to the territorial distribution of the vote. More specifically, in the 2018 election participation was exceptionally high, especially in the south which in some regions saw electors returning to the polls. But electoral volatility is still high. Both factors affected the extraordinary success of new protest parties and collapse of the traditional parties. Traditionally in the south the vote has gone to moderate and pro-government parties, but this time in all constituencies the M.5.S., an ‘eccentric’, protest or populist party-movement, which in many cases took over 40 per cent of the votes, with a peak of 50 per cent in Campania and Sicily. Further, the wave of protest votes favoured another party with no previous support in this geographical area, the League. It may be too soon to say whether these changes in the form and dynamics of the party system are long-lasting and able to achieve a lasting change in the political spectrum, but so far the outcome of election has given a further push to the radicalization of both electoral demand and supply.  相似文献

Radiocarbon and U-series methods (230Th/U and 231Pa/235U) for absolute age determination have been applied to some fossil samples from Grotta Juntu, in North Eastern Sardinia (Italy). The remains belong to the endemic deer species Praemegaceros cazioti, which is here represented by an almost complete skeleton. The three dating methods lead to concordant ages of about 7500 years BP, indicating that the skeleton was maintained as closed system after burial. Taking into consideration these results, Praemegaceros cazioti from Grotta Juntu is now the youngest representative of this species in Sardinia.  相似文献

Although 'lake-dwellings' existed from the middle of the fifth millennium to the eighth century BC, the entire phenomenon was not a continuous one. There are several periods when the lake shores were abandoned and subsequently reoccupied. The pattern of occupation depends on cultural as well as environmental factors, amongst them the topography and the climate.
Unlike the southern part of the Alps, which seems to have had a more regular occupational pattern throughout the Neolithic and the Bronze Age, the northern Alpine region shows a marked discontinuity along most of the lake shores. Two relevant breaks in lake-shore occupation are known within the northern Alpine region Bronze Age. The first occurred between the 24th and the 20th centuries BC, and the second from the 15th to the middle of the 12th century BC.
The Early Bronze Age site of ZH-Mozartstrasse, situated on the western extreme of Lake Zurich (Switzerland), was abandoned immediately before the beginning of the second major occupational gap in 1503 BC. Two other Early Bronze Age sites namely Bodman-Schachen 1 on Lake Constance, and Arbon-Bleiche 2 on the Swiss part (the southern shore) of the same lake, follow a similar chronology in occupation; and they were both abandoned in the last decade of the 16th century BC.
A possible cause of abandonment is discussed in this paper using an environmental approach related to an abrupt change of climatic conditions which resulted in an increase of the lake levels which forced those prehistoric populations to leave the proximity of the lake shores. Following the implications of pollen and sedimental analyses, the transformation of the Bronze Age landscape caused by the lake water invasion will be simulated with the help of CAD and GIS computer programs.  相似文献

In the 1960s, a reduction in the time spent at work promised an increase in leisure time. Architects and planners thought that the effects of this could lead to a new form of city. Nowadays, new changes in production, technology and gender relationships de-synchronize the time regime and have fundamentally changed life in cities. Tourism and globalization exchange across the world different cultures of time. In France, the UK, and other European countries time policy is dealing with the problems arising from these changes. This article presents a short overview of time planning in Italy in two main domains: time for care, and city time. It focuses on issues such as the social demand for new shops's and services' opening hours, or how the life cycles of individuals and populations are accommodated in urban spaces. Other problems, usually not thought of in terms of time concerns, such as rehabilitation of blighted areas, historic preservation and traffic flow control, may also be treated through a time approach. Two models of planning process are presented at the end of the paper.  相似文献

This paper introduces a new methodology to identify space-time patterns of regional resilience using a micro-level approach. The novel empirical tool combines geographically weighted regression with panel stochastic frontier analysis with endogenous covariates. The analysis is implemented on a panel of farm holdings operating in the Italian wine industry, focusing on the impact of a major institutional change. The results show the effectiveness of the new procedure in identifying geographical clusters of wine producers who reacted to the shock in similar ways. The responses are found to be homogeneous within specific territories and heterogeneous between regions.  相似文献

This study details an application of eco-cultural niche modeling (ECNM) using two modeling architectures—a genetic algorithm (GARP) and maximum entropy (Maxent)—aimed at examining the ecological context of sites with archaeological remains attributed to the culture termed the Badegoulian (ca. 22–20 k cal BP), which dates to the middle part of the Last Glacial Maximum (ca. 23–19 k cal BP). We reconstructed the ecological niche of the Badegoulian and assessed whether eco-cultural niche variability existed within this technocomplex. We identified two broad but distinct spatial entities in the distribution of Badegoulian sites based on lithic raw material sources and circulation, and found that these spatial units share a similar ecological niche. We discuss the implications of territorial differentiation within this niche in light of research on land use by culturally affiliated groups within a broad cultural entity. We propose that Badegoulian circulation networks reflect distinct social territories associated with particular conditions within a single ecological niche. This study illustrates the utility of combining ecological niche reconstructions with archaeological data to identify and evaluate diachronic trends in cultural continuity for situations where such patterns may be missed when the focus of study is restricted solely to lithic technology and typology.  相似文献

The Mediterranean region has been increasingly receiving attention in recent years. This is due to the heterogeneity of the countries composing it, which raises several problems in business collaborations, but also unfolds several cross-national economic opportunities among Mediterranean countries. The analysis of cultural and creative industries can be useful to show that this area has many similarities, making intercultural exchange and cross-national economic development possible. This research starts from the comparison of three main Mediterranean countries situated both in Europe and outside, Italy, Spain and Turkey, and aims at highlighting the most striking similarities and differences of their features. The creativity specialization found in this region is alike, which allows us to begin to discuss the idea of a Mediterranean creativity.  相似文献
