Two equid species have been documented in the Pleistocene of the Iberian Peninsula, the horse Equus caballus, and the Eurasian hemione Equus hydruntinus. While the former survived the Holocene–Pleistocene until now, the timing for the extinction of the latter is unclear. Scarce, fragmented archaeological remains assess the presence of small equids living in the Holocene of Iberia. Those could possibly correspond to the Eurasian hemione although unambiguous morphological identification is often not possible. With the find of an equid tooth from Leceia, a Chalcolithic fortified site in Portugal, and using both morphological and mitochondrial genome analyses, we demonstrate for the first time the presence of a new equid species in Holocene Iberia, namely a donkey (Equus asinus). Radiocarbon dating of the tooth to Cal 2340–2130, and 2080–2060 BC with 95% probability, demonstrates that donkeys were present in Iberia well before the arrival of Phoenicians in the first quarter of the first millennium BC (900–750 years BC), which were considered so far as the first who introduced donkeys in the region. 相似文献

The East African coast is a rich domain for underwater cultural heritage, whose archaeological remains are only beginning to reveal the extent of indigenous nautical technology, regional and international social contacts, and far-reaching maritime trade routes sailed for millennia. The diversity of remains found under water range from cultures up and down the East African coastline to further afield: from China, points surrounding the Indian Ocean, to the Persian Gulf, Middle East and Europe. In Mozambique, important steps to investigate and preserve this heritage have been taken over the last 20?years by several groups of local scholars in collaboration with international research institutions. However, this heritage, especially that which lies along the northern Mozambique coast, has also been subjected to extensive and serious disturbance by commercially-oriented salvage programs. These salvage activities have not only had a very negative impact on the state of the cultural resources themselves, but have also prevented the access of legitimate scholars to these resources??particularly grave is the intervention at Mozambique Island, a UNESCO World Heritage Site. Among the meritorious efforts to mitigate this situation, in Mozambique and world-wide, the 2001 UNESCO Convention for the Protection of the Underwater Cultural Heritage is an outstanding initiative and needs to be ratified by Mozambique and other East African states. 相似文献

Some researchers detected a new-found subsidiarity in rural policy after England’s 2001 Foot and Mouth Disease epidemic, with regional and sub-regional institutions working together to implement an economic recovery strategy. While such research began to link debates on the new regionalism and the rescaling of agro-food governance, its conception of the latter focused too narrowly on the ‘turn to quality’, thereby overlooking other important aspects of food relocalisation. Based on interviews conducted in England’s South West and West Midlands regions, this paper examines whether the attitudes of key actors from regional and sub-regional governance institutions provided a sound basis for partnership working on the food relocalisation policies recommended in the Government’s Strategy for Sustainable Farming and Food. It finds different attitudes on the part of regional and sub-regional actors, with the former favouring regional foods and the latter local foods. Despite scepticism from both groups about the ability of the England Rural Development Programme (2000–2006) to promote food relocalisation, grants were awarded to both regional and local food entrepreneurs, suggesting that the programme contributed more to food relocalisation than previously thought. 相似文献

This article describes the dynamical behavior of free-standing block structures under seismic loading. A comprehensive experimental investigation has been carried out to study the rocking response of four single blocks of different geometry and associations of two and three blocks. The blocks, which are large stones of high strength blue granite, were subjected to free vibration, and harmonic and random motions of the base. In total, 379 tests on a shaking table were carried out in order to address the issues of repeatability of the results and stability of the rocking motion response. Significant understanding of the rocking motion mechanism is possible from the high quality experimental data. Extensive experimental measurements allowed to discuss the impulsive forces acting in the blocks and the three-dimensional effects presented in the response. 相似文献

Performance-based earthquake engineering methodologies often require a probabilistic model of structural demand. Since observations masking the probability distribution of the majority of the data are frequently found, robust estimation methods are proposed to estimate the probabilistic model parameters (i.e., central value and dispersion). The performance of thirty-three robust dispersion estimators is evaluated, for different sample sizes, using the chord rotation, curvature, shear force, and inter-story drift demands obtained after analyzing five reinforced concrete structures under real earthquake records scaled to several intensities. Based on the results, combinations involving dispersion and central value (defined in a companion article) estimators are proposed. 相似文献

In the last few decades many studies have underlined the role of philhellenism in shaping the Risorgimento as a transnational movement. But philhellenism also had a significant impact in embodying the pre-unification Italian state in a new imaginative framework, marked by the binary oppositions of civilized/barbarian, liberal/despotic and north/south. This article analyses the influence of philhellenism in shaping the imagery of the Kingdom of Sardinia in the eighteenth and nineteenth centuries and the role played by this local imagery in promoting opposing patriotisms within the national political sphere in the years leading up to the unification of Italy. Cavour’s moderate party stressed the positive impact of the Piedmontese domination over the island of Sardinia in order to underline Piedmont's image as a force of modernization of a land strongly marked by feudal despotism and pastoral violence. By contrast, Mazzini and the democrats also deployed a philhellenic narrative scheme to explain the backwardness of Sardinia with reference to the despotic and ‘oriental’ character of the Piedmontese domination in an attempt to encourage opposition to unification under the leadership of the subalpine government. 相似文献

Landscapes of the Ghost Dance: A Cartography of Numic Ritual 总被引:1,自引:0,他引:1

Recent historical and ethnographic research indicates that the study of ritual behavior could be greatly enhanced by combining parameters of place and landscape use with interpretation of material culture. This strategy is especially useful for identifying the archaeological record of ritual among societies that incorporated topographic features and natural resources into their liturgical order. In this article we apply a behavioral framework to the study of Numic ritual technologies. By intergrating ethnographic and historic data on the geography, practice, and material culture of the nineteenth-century Nevada Ghost Dance, we demonstrate how this framework helps to determine the configuration of a ritual place and its position relative to other ritual and nonritual places. 相似文献

This study examines the potential socio-spatial impacts of a new series of marine protected areas (MPAs) on fishers in Moorea, French Polynesia. The establishment of the MPAs is contextualized within recent and historical processes of economic development and theories of women in development and gender, culture and development. Seventy adults from three neighborhoods in Moorea were interviewed. Analysis of the data provides new information about the characteristics of fishing in Moorea. Unlike most fishing cultures and communities throughout the Pacific Islands, men and women in Moorea have similar, as opposed to segregated, spatial patterns of fishing activities and fishing methods. The study also points out the potential negative impacts of the MPAs on both men and women, particularly younger and lower-income fishers. 相似文献
