The deposition of Early Neolithic material within tree-throw hollows in described, and the possible role of fallen trunks as places of occupation, settlement foci and landscape markers is discussed. Having implications for the interpretation of ubiquitous later Mesolithic pit dwellings, the evidence suggests a continuity of forest 'identity'. Accordingly, patterns of clearances are also explored in relationship to modes of occupation, and the employment of 'big wood' in Neolithic monuments discussed. 相似文献

Almost all of the obsidian used to craft stone tools in the Near East from the Palaeolithic onward originated from volcanoes in two geographic regions: Central Anatolia and Eastern Anatolia. Five decades of obsidian sourcing has led to the view that Central Anatolian obsidians largely followed the Mediterranean coast and rarely reached farther east than the Middle Euphrates, whereas Eastern Anatolian sources almost exclusively supplied sites east of the Euphrates. This paper discusses the identification of Central Anatolian obsidian artefacts at the Bronze-Age site of Tell Mozan (Urkesh) in northeastern Syria. Most of the obsidians at Tell Mozan (97%) came from the Eastern Anatolian sources, as expected from established distribution models. Artefacts of Central Anatolian obsidian, however, were excavated from one well-constrained context: the deposits on a palace courtyard that date to the height of the Akkadian empire's influence at this third-millennium Hurrian religious and political centre. In particular, the obsidian came from the Kömürcü source of Göllü Da?. Potential explanations for this exotic obsidian are discussed. This obsidian might have “piggybacked” on the distribution of Central Anatolian metals or arrived at this city as royal gifts or prestige items. Other discussed mechanisms include Akkadian-linked changes in either territoriality involving pastoral nomads responsible for the arrival of Eastern Anatolian obsidians or identity construction of elites based on involvement in Central Anatolian economic and political networks. 相似文献

The results obtained from the multi-analytic compositional characterization of ceramic pastes and paints of the Santa María style, from the El Bolsón valley (Belén Department, Catamarca Province, Argentina), are presented here. This pottery style had a wide regional distribution in Northwestern Argentina between ca. 1000 and1600 ce and is characterized by its complex iconography painted in black, cream and red. The analyses show that the containers correspond to the technical tradition of using grog temper and suggest that its manufacture involved a double firing process. This reveals a new practice for the time. 相似文献

Policies concerning undocumented immigrants are inevitably ambivalent, creating uncertainty and confusion in the implementation process. We identify a clear example of this ambivalence —U.S. law setting standards for determining the credibility of asylum seekers—that resulted in an increase in asylum grants despite policymakers' intention to make it harder for individuals to obtain the status. We argue that this law, The REAL ID Act of 2005, sent mixed messages to immigration judges (IJs), street-level bureaucrats who implement immigration policy. It increased IJ discretion, but set vague limits. We theorize that IJs, behaving in a bounded rationality framework, use their professional legal training as a short-cut and look primarily to the courts for guidance. Our evidence supports our argument. After the passage of the REAL ID Act, IJ decision-making is more closely aligned with the preferences of their political and legal principals, and, in the final score, the federal circuit courts are the winners. 相似文献

Archaeological evidence of ceramic production most commonly consists of locally procured raw materials. Excavations at Tell el-Timai in Lower Egypt recovered raw fine marl clay from two transport jars in the vicinity of pottery kilns dating to the 4th century b.c. Production wasters of small perfume bottles produced in the same fine marl clay were found inside the kilns. The marl clay inside the jars pointed to an origin outside of Lower Egypt. Samples of the clay and wasters, along with a confirmed locally sourced sample, were subjected to X-Ray Fluourescence (XRF) analysis, revealing significant differences in their chemical compositions. The results of the analysis are compared to published Egyptian data and an Upper Egyptian provenience is suggested because the raw clay is consistent with available comparative XRF data. 相似文献

ABSTRACTThe “Quartel das Esquadras” is an 18th century infantry barrack located within the limits of the bulwarked fortress of Almeida, in Portugal. An ongoing adaptive reuse project of the building aims to recover its full capacity and also its importance, by implementing a variety of new uses. The architectural intervention results in the need of the structure to withstand new and diverse imposed loads. As the current configuration of the structure will be altered, the main objective of this article is to evaluate the suitability of some of the proposed structural interventions. The current condition has been characterized following a multidisciplinary approach comprising historical research, visual inspection, non-destructive testing, and structural analysis to identify the possible sources of major structural problems. A portion of the building particularly affected by the alterations has been selected to carry out structural analysis. A comparative safety assessment of the selected area in both current and altered condition has been done through finite element modelling and nonlinear static analysis, resulting in an identification of the weaker points against the new implemented loads and alterations. Finally, proposals for the implementation of the studied intervention, as well as recommendations for future research and analyses, have been given. 相似文献

In recent decades in Europe, municipalities have promoted many poorly qualified and widespread industrial parks. These policies have caused various problems such as oversupply of industrial land, obsolescence and high vacancy rates. The future of these sites is uncertain and has become a key issue in planning. Nowadays, policies are focused on upgrading these sites and on implementing regional coordinated practices. This paper describes a methodological approach to identifying a subregional network of industrial parks in the Ave valley, Portugal. The network is based on the parks’ attractiveness and has the purpose of supporting planning policies in terms of upgrading and providing new sites. The approach was based on a multi-criteria analysis whereby the parks were ranked according to their attractiveness considering their coverage in terms of infrastructures, services and accessibility. Results show that the majority of the existing and planned parks, even if upgraded, will not be very attractive and will be limited to a municipal scale due to structural problems related to their location and poor coverage. Moreover, the paper also discusses the challenges in implementing this planning approach at a subregional level. Despite the specificities of the case study, this methodology could be adopted in similar studies. 相似文献
