The highest platforms of As Laias, a settlement located in northwest Iberia, were used for storage during the Iron Age and until the turn of the Era. In this time-span, the whole hilltop – the croa – was a walled enclosure mostly used for storage and due to recurrent fires affecting the settlement's terraces, abundant plant remains were preserved in overlying wattle and daub storage structures. 相似文献

Palynofloras from an outlier of Tertiary sediments in the One Tree Hill area north of Adelaide are nonmarine and correlate with similar assemblages from Middle Eocene North Maslin Sands from Maslin Bay and Golden Grove. Although there are similarities with time-equivalent Lower Nothofagidites asperus Zone palynofloras in the Gippsland Basin, a number of species in the South Australian palynofloras do not extend below the Late Eocene in the Gippsland sequences. This indicates earlier appearances for these species in southcentral Australia. The sediments overlie a highly weathered bedrock palaeosurface, indicating that a phase of significant weathering occurred prior to the Middle Eocene. A number of selected taxa are illustrated and their distribution in the palynofloras is discussed. Two new species, Proteacidites mildenhallii and Proteacidites parrawirrensis, are described and one species, Rhoipites byfieldensis, is emended. 相似文献

In addition to being the object of policy and legal initiatives, families of migrant origin have become a focus of debate concerning differences and its limits. Migrants themselves, however, are also reflecting on how to manage family relationships in a changing world in which migration is mostly transnational. This article aims to discuss the influence of religious participation on the reconfiguration of processes of family dynamics promoted by three groups of migrant women who, while settled in Lisbon, maintain transnational ties with their countries of origin and with various diasporic spaces. Guiding research questions are: to what extent does religious participation provide migrant women with connections, networks and other intangible resources? How are these resources mobilised as ‘bonding' and ‘bridging' social capitals? Can such capitals become a conduit for the redefinition of family relations and female self-narratives? Comparative analysis confirms that the three groups discussed not only mobilise religious belonging and ties to generate resources, but also convert these connections into social (and other forms of) capital, thus triggering desired changes that affect the lives of their children and families in both the short and long term. While migration does not alter long-standing patterns provided by their own respective sociocultural frames of belonging, our findings reveal that the three groups of interlocutors use religious participation to explore tactics, social capitals and mobility spaces and, further, to negotiate, without subverting, specific family inequality dynamics. 相似文献

Moisture transfer in the walls in direct contact with the ground leads to the migration of soluble salts, which are responsible for many building pathologies. The treatment of rising damp in historical heritage walls is a very complex procedure. The traditional techniques currently used to minimize rising damp are, in most cases, slight effective or too expensive, especially when dealing with walls of considerable thickness and/or heterogeneous materials such as the historical monuments. The main purpose of this work is to present the experimental results of the rising damp treatment conducted, over 3 years, in the Vilar de Frades Church, in northern Portugal, using the wall-base ventilation technology. The results showed that, for this particular climate conditions, the best solution is to operate seasonally, with outside air admitted to the system during summer months and inside air admitted to the system during winter months. 相似文献

ABSTRACTDespite the high vulnerability of historic structures to earthquakes, the approaches for evaluating seismic demand and capacity still appear inadequate and there is little consensus on the most appropriate assessment methods to use. To develop an improved knowledge on the seismic behavior of masonry structures and the reliability of analysis tools, two real-scale specimens were tested on a shake table, and several experts were invited to foresee failure mechanism and seismic capacity within a blind prediction test. Once unveiled, experimental results were simulated using multi-block dynamics, finite elements, or discrete elements. This article gathers the lessons learned and identifies issues requiring further attention. A combination of engineering judgment and numerical models may help to identify the collapse mechanism, which is as essential as it is challenging for the seismic assessment. To this purpose, discrete modeling approaches may lead to more reliable results than continuous ones. Even when the correct mechanism is identified, estimating the seismic capacity remains difficult, due to the complexity and randomness of the seismic response, and to the sensitivity of numerical tools to input variables. Simplified approaches based on rigid body dynamics, despite the considerable experience and engineering judgment required, provide as good results as do advanced simulations. 相似文献

A human femur diaphysis in the form of a burin was excavated from a secondary burial context containing osteological remains and industry in the Archaeological Complex of Perdigões (Portugal). The majority of these evidences are thermo‐altered and highly fragmented. Radiocarbon dates for this context place it in the middle 3rd millennium BC. Typological analyses indicate that the human femur fragment is a burin, and use‐wear comparisons suggest that it was used to drill hide. Copyright © 2016 John Wiley & Sons, Ltd. 相似文献

We apply Eco-Cultural Niche Modeling (ECNM), using the Genetic Algorithm for Rule-Set Prediction, to reconstruct the ecological niches exploited by Middle Solutrean and Upper Solutrean populations during the latter stages of Heinrich Event 2 and the early part of the Last Glacial Maximum, respectively. We focus on the Upper Solutrean technocomplex and its regionally distinct styles of hunting weaponry to investigate whether regional cultural variability reflects a link between material culture and ecology. Our analytical approach uses archaeological and geographic data in conjunction with high-resolution paleoclimatic simulations and vegetation reconstructions for the two climatic phases in question. Our results indicate that cultural choices behind the production of specific projectile point types have at some level an ecological basis and are linked to particular environments. We also find that the identified pattern of Upper Solutrean territoriality has an ecological foundation, but that its stylistic expression in the variation of diagnostic armature types is likely a byproduct of cultural drift. We argue that ECNM is an effective means with which to evaluate the paleoecological pertinence of archaeologically defined artifact types and to identify the ecological and cultural mechanisms underlying material culture variability. 相似文献

We have sought to identify an aspect of the repression of Enlightenment cosmopolitanism complementary to the creation of national identities in XIXth-century Europe and the intervening war period. The idea of a common civilization would be maintained by the reciprocal capacity of translating national languages, because of their Indo-European common origins. The utopia of the language would replace the material route of the Enlightenment. It is the failure of the construction of European Indianist myth and not its success which explains the ideological diverting of the relations between language and nation. The missed promotion of the Gypsy language in the academic world illustrates this failure perfectly. After the First World War, the transformation of the principle of nationalities in ethnopolitics removed even the memory of this common ambition. 相似文献
