We present the results of instrumental neutron activation analysis of ceramics recovered from the Solomon Islands, associated with Alvaro de Mendaña y Neira's 16th century colonizing expedition to the region (c.1595–6). Based on the chemical and typological data and previously published petrological and geochronological research, this study assigns the provenance of the ceramics variously to Peru, Panama, Spain, China and Thailand. A comparison of the provenance results with historical records related to Mendaña's voyage also shows the value of the archaeological assemblage in providing a detailed picture of provisioned ceramic types and their provenance.  相似文献

The rise of social assistance in Brazil has been remarkable. The 1988 Constitution signalled a renewed ‘social contract’ leading to citizenship‐based social assistance providing guaranteed income to older and disabled people in poverty. Municipal activism in the 1990s extended the provision of direct transfers to all households in poverty through Bolsa Escola and other programmes later consolidated into Bolsa Família. This article studies the origins and evolution of social assistance institutions in Brazil, paying due attention to the role of ideas and politics.  相似文献

The sun, sea and sand model that has characterized the Spanish tourism sector and has caused Spain's tourist sector to become a world-class industry is actually undergoing drastic changes. This model is based on the existence of major tourism destinations characterized by high levels of industry specialisation, which makes them a target of analysis as tourism clusters in which the geographic concentration of synergies reinforces the competitive position. In this study, Spanish tourism clusters are identified using quantitative methods and the current validity of the economies of location that have made them possible are also analysed. Although all the identified clusters can be defined as mature and became less significant during the last decade in Spanish tourism, according to the results the creation of externalities measured in terms of higher generation of profit is higher in companies belonging to the tourism clusters than in those outside of them.  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

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

This paper assesses the impact of European ceramics on preexisting American potting technologies. Specifically we investigate the technological features of pigments used for production of colonial American majolica. In order to achieve this goal, majolica sherds from Puebla (4), and Oaxaca (2), both in Mexico, from Antigua (Guatemala) (2), from Panama (1), and from Mission San Luis (Florida) (5) were analyzed by synchrotron micro-X-ray diffraction (μ-XRD). Eleven out of these fourteen samples were also analyzed by scanning electron microscopy (SEM). The combination of micro-chemical and micro-structural techniques provides a cross sectional profile of the constituent minerals present ultimately providing information about the nature and distribution of the pigments used in their decorations, their dissolution in the glassy matrix, and the formation of crystalline compounds. Our results reveal significant differences among productions.  相似文献

Over more than a century, several proposals have been made on the composition and technical features of the pictorial recipes used by Levantine prehistoric painters. In this paper all these proposals are surveyed and tested through systematic experiments to determine the technical affordance of pigments and binders in different pictorial recipes. Experimental results were then used as independent analytical parameters employed as diagnostic criteria to systematically study an archaeological sample of nine sites located in the Maestrazgo region (Spain) and their surroundings. Results reveal that out of 112 experimental recipes, only 16 afforded the production of paintings technically similar to Levantine rock art.  相似文献
