Through the analysis of a wide range of Italian mass-market magazines and a selection of public opinion surveys, this essay investigates widespread images and perceptions about nuclear issues in Italy during the Sixties. It considers the views of Italians about nuclear weapons within foreign policy debates, as well as the wide range of fears expressed about the atomic bomb. The article also analyses the image of anti-nuclear movements, as well as Italians’ views on disarmament and the easing of international relations after 1962. Deeply influenced by ideological divides and filtered through the mechanisms of mass culture – which tended to trivialise the bomb – these widespread representations of nuclear issues offer a unique perspective on Italians’ beliefs, fears, and hopes during a time of deep socio-economic change and shifting political equilibriums in the country.  相似文献

Charcoal and charred seeds at five Bronze Age archaeological sites discern ancient land use in the eastern Mediterranean. Seed frequencies of orchard crops, annual cereals and pulses, and wild or weedy plants are used to characterize plant utilization at different archaeological sites on the island of Cyprus, in the Rift Valley of Jordan, and in the Jabbul Plain and along the upper Euphrates River valley in Syria. Seed to charcoal ratios provide proxies to determine the relative usage of dung versus wood for fuel across the ancient Mediterranean landscape. Greater charcoal and lower charred seed values are interpreted to represent a wooded environment, while higher amounts of charred seeds and minimal wood charcoal suggest a much great use of dung as a fuel source. Interestingly, Politiko-Troullia (Cyprus, Cypriot archaeological sites are, by convention, named for the nearest modern village (Politiko), followed by an italicized toponym (Troullia) referring to the plot of land that incorporates the site) has the lowest seed to charcoal ratio, suggesting its residents primarily burned wood and that the landscape surrounding Troullia remained relatively wooded during the Bronze Age. In contrast, villagers at Tell el-Hayyat (Jordan) utilized a mixture of wood and dung, in contrast to Tell Abu en-Ni’aj (Jordan), and especially Umm el-Marra and Tell es-Sweyhat (Syria), where inhabitants relied solely on dung fuel. Comparative analysis and interpretation of seed and charcoal evidence thus illustrates the variety of fuel use strategies necessitated by the dynamic and diverse Bronze Age landscapes of the Eastern Mediterranean.  相似文献

An absence of settlement features during the Central European Corded Ware period (Late Eneolithic, 2900–2300 BC) has been interpreted as a reflection of mobile pastoral subsistence. Recent analyses of the Late Eneolithic archeological context reveal that the Late Eneolithic exhibit evidence of sedentary agricultural activities similar to the Early Bronze Age. Since the archeological analyses are not clear cut, we tested mobility pattern differences between the Late Eneolithic and Early Bronze Age using biomechanical analysis of the tibial midshaft cross-sections. The total sample of the 130 tibiae representing five archaeological cultures was used. The results of the tibial midshaft geometry do not support the hypothesis about different mobility in the Late Eneolithic and Early Bronze Age. This conclusion is supported by nonsignificant differences between the Corded Ware females and the Early Bronze Age females. Higher absolute values for the Corded Ware males should be explained either by stochastic variation or by differing amounts of physical demands despite a generally similar pattern of subsistence of the Late Eneolithic and Early Bronze Age. One of the Early Bronze Age samples, the Wieselburger group, is an exception because the individuals show both reduced overall size and bending resistance of the tibial parameters not only in comparison with the Late Eneolithic but also to the rest of the Early Bronze Age. The results suggest that the behavioral processes which affected the tibial midshaft biology operated during the Late Eneolithic and Early Bronze Age as a mosaic across time and between/within cultures.  相似文献

Natron deposits, the best known of which being those at Wadi Natrun in Egypt, have been used as the flux in the production of vitreous materials from the early 4th millennium BC onwards. In the present paper, the history of the use of natron as a flux is traced from its beginnings in the glaze of Badarian steatite beads, through its use in glass production starting in the 1st millennium BC, until its apparent shortage during the 7th to 9th centuries AD, and its subsequent replacement by plant ash during the 9th century AD. Documentary evidence for possible natron sources in Egypt, including the Wadi Natrun, and around the eastern Mediterranean is summarised, and the results of recent fieldwork at the Wadi Natrun and at al-Barnuj in the Western Nile Delta are presented. The possible reasons for the apparent shortage of natron from 7th to 9th centuries AD and its subsequent replacement by plant ash as the flux used in glass production during the 9th century AD are then considered. These include the possibility that, because of the massive scale of glass production, the demand for natron exceeded its supply; the possible effect of climatic changes; and the potentially disruptive role of political events in the Wadi Natrun–Delta region.  相似文献

Climate deterioration at around the time of the Bronze Age/Iron Age transition has for long been argued to have resulted in upland abandonment in northern and western Britain, and recent research has provided evidence that a major climate downturn from 850 cal BC caused settlement abandonment in western Europe and potentially worldwide. It is, however, unclear to what extent only ‘marginal’ sites were affected, due to the lack of any systematic attempt to view the evidence for settlement and land-use change across a range of landscape types with differing sensitivities to environmental change. This paper addresses this issue by an evaluation of 75 pollen sequences spanning the late Bronze Age and early Iron Age in Britain to assess whether climatic deterioration was sufficient to cause widespread land abandonment. The results provide no evidence for wholesale land-use change at this time; the overall picture is one of continuity of land use or even increased agricultural activity. There are, however, hints of regional variability, with a greater tendency to abandonment of upland areas in Wales, and signs of woodland regeneration in agriculturally productive areas of lowland central southern England. The latter pattern may reflect a combination of rising ground-water levels affecting local land-use in the immediate vicinity of the mires which provide the source of the pollen data, against a backdrop of regional-scale social and economic changes at the Bronze Age-Iron Age transition.  相似文献

In this study, arsenic, copper and lead content of a group of human and animal bones recovered from the Early Bronze Age ?kiztepe site have been analyzed using ICP-MS method. Average arsenic value of 90 femur bones of a human was found to be 15.0 ± 5.79 ppm which was varied among age and sex groups, and among species. Origin of arsenic accumulation in bones was diagenetic because overall the groups were highly variable. The distribution of metallic items among the burials had a big affect on the arsenic uptake of the bones. Copper and lead values supported the diagenetic arsenic accumulation in the bones as well. Their values on the bones were not as high as those for the individuals involved in metal working activities in the ancient world. Judging from these data, it is concluded that ?kiztepe people did not produce the manufactured metallic items using arsenical copper but might have been imported from the other sites.  相似文献

Two types of electrical conductivity sensors were evaluated to prospect circular ditches surrounding former Bronze Age burial mounds, complementing aerial photography. The first sensor was based on the electrical resistivity (ER) method, while the second sensor was based on frequency-domain electromagnetic induction (FDEM). Both sensors were designed with multiple receivers, which measure several depth sensitivities simultaneously. First, the sensors were tested on an experimental site where a rectangular structure with limited dimensions was dug in a sandy soil. The structure appeared as a higher conductivity anomaly in the low-conductivity sand. Then, both methods were applied on two Bronze Age sites with different soil properties, which were discovered by aerial photography. The first site, in a sandy soil, gave only very weak anomalies. Soil augering revealed that the ditch filling consisted of the same sandy material as the surrounding, therefore this filling was not able to cause a high-conductivity contrast. Due to its lower sensitivity to noise in the low-conductive range, the ER-sensor produced a more pronounced anomaly than the FDEM-sensor. The second site was located on top of a ridge with a shallow substrate of Tertiary, coastal sediments. The ditch was very clearly visible on the sensor maps as a conductive low. At this location, the soil augering revealed that the ditch was dug through an alternating clay-sand layer and subsequently filled up with silty material from the topsoil. Overall, the shallow receiver separation produced anomalies that were both stronger and that corresponded better to the geometry of the ditches. The other receiver separations provided more information on the natural soil layering, and in the case of the ER-array they could be used to obtain a cross-section of the actual electrical conductivity with 2-D inversion modelling. The results of this study proofed that conductivity sensors can detect Bronze Age ditches, with varying contrast depending on the soil geomorphology. Moreover, the sensor maps combined with soil observations by coring provided insight in the environmental conditions that influence the contrast of the anomalies seen on the aerial photographs and the sensor maps.  相似文献

A collection of 54 bronze artefacts recovered from the inland settlement of Castro dos Ratinhos (Portugal) and belonging mainly to the 9th–8th centuries BC, was studied by the use of non-invasive and micro analytical techniques. EDXRF, Micro-EDXRF, SEM-EDS and Optical Microscopy were used to determine the alloy composition and to identify the different thermo mechanical operations applied in the production of the artefacts. Results show that the collection is entirely composed of good quality binary bronzes (with an average tin content of 10.1 ± 2.5%). Alloys with higher tin contents were kept in as-cast condition and used in the making of ornaments, while tools were often finished with forging and annealing operations. Despite the existence of some Orientalising features in the Castro dos Ratinhos, e.g. rectangular habitat structures, wheel-turned ware and amphorae, the exclusive use of binary alloys with a narrow range of tin content seems to be associated with an indigenous metallurgical tradition inherited from the Late Bronze Age. This may indicate that the Phoenician interaction within the inland indigenous communities was a slow and selective process, probably dependant on the social-economic and cultural development of local communities.  相似文献
