The recent re‐analysis of the Maglemosian faunal assemblages from Mullerup and Lundby Mose (Sjælland) has led to the discovery of new hunting injuries in the Danish Early Mesolithic. In total, including the two cases already published, two examples come from the Lundby Mose site, and seven from Mullerup, including embedded flint fragments and perforations. Such new data emphasise the need for meticulous re‐analysis of bone assemblages, relying on experimental work on projectile impacts, in order to increase the number of such discoveries. The link with weapons and hunting techniques and the question of the frequency of projectile impacts during the Danish Mesolithic are discussed, as well as their significance in terms of mobility of human groups, particularly in the case of healed wounds.

This article aims to challenge the widespread consensus that Rio de Janeiro is a divided city by deploying two concepts in critical cartography: cartographic silences and cartographic calculations. As a kind of unconquered territory, a terrae incognitae, favelas were silenced on many of Rio de Janerio's maps over the last century. When these places began to be mapped, and converted to terrae cognitae, power relations often become even more apparent because of the intention to make it legible for purposes of intervention. By analyzing maps published in the mainstream Brazilian press throughout the last century, this article explores how national press often portrays Rio de Janeiro as a city divided between formal neighborhoods, where the state apparatus can ensure the rule of law, and favelas, where parallel politics enforce local forms of governance. In order to disseminate this image of the city, maps can play an important role, locating different urban zones and reinforcing old stereotypes. Despite many studies that focused on both material and embodied forms of state presence within favelas, maps can be an important source of information to understand persistant representations of favelas as excluded and divided places. 相似文献

ABSTRACTWhile studies on recovery bias are numerous in the literature, the current research focuses on defining best practices in field collection techniques to provide a more accurate representative of site constituents, particularly fish remains. Methods to determine best practices included use of 1/4-inch, 1/8-inch, and 1/16-inch mesh to process excavated material from 10 × 10?cm and 40 × 40 cm-sized bulk column samples and from a 1 × 1 m test unit. Fish remains were compared to determine density and diversity differences between the samples and how these different data sets may impact cultural interpretations. This research shows that while collection of larger column samples processed using a smaller mesh size provides a more robust data set, the taxonomic richness present in a 1 × 1 m test unit provides complimentary data that are critical to understanding subsistence trends as a whole. 相似文献

汉代的铸钱遗址中出土了大量铸造铸钱金属范的阳文陶范,阳文陶范既反映出了铸造金属范时的铸型,又可看出所铸造的铸钱金属范的铸型.为揭示铸钱金属范的铸造工艺及变迁,本工作从铸造工艺角度对阳文陶范进行分析,通过对汉代阳文陶范出土概况的统计,了解了阳文陶范铸型的变迁.以西安相家巷和窝头寨铸钱遗址采集的阳文陶范为基础,对陶范的面层与背层进行了X射线荧光成分分析,在电子探针下对型腔面进行了形貌和成分分析.分析结果表明,阳文陶范分层制作的原因是为了将模上的钱币铭文和形状清晰地复印到陶范上,型腔面的检测不能表明是否使用了表面涂料. 相似文献

Prehistoric reduction sequences of proboscidean ivory have been described and discussed within the Russian and European Upper Paleolithic archaeological literature. A culturally modified proboscidean tusk (Mammuthus sp.) in Seward Peninsula, northwestern Alaska, displays longitudinal grooving, providing an insight into a reduction technique rarely described within North American archaeological literature. Similar reduction sequences have been described for the production of bone, antler and walrus ivory artifacts in the North American prehistoric record; however, examples on proboscidean ivory are extremely rare. 相似文献

ABSTRACTFire is one of the most severe threats to stone applied in civil engineering and architecture. In most cases, its effects are irreversible and have long-lasting repercussions. In addition to aesthetic alterations, fire can also induce important mineral-chemical, physical, and mechanical changes in stone. Research concerning the effects of fire on stone materials in recent decades has been providing valuable knowledge to inform present and future conservation and restoration actions. In this literature review, the properties and techniques used for studying the effects of fire on stone materials are appraised, summarized, and compiled. A comprehensive and practical overview of those effects is also given. Open porosity and P-wave ultrasonic velocity are the physical and mechanical properties that have been studied most. Other frequently researched areas include chemical-mineralogical changes, color, density, water absorption, uniaxial compressive strength, and modulus of elasticity are also very frequently investigated. 相似文献

The article deals with the use of metal ties in an ancient and stratified urban context, the city of Genoa, starting from the notarial documents preserved in its State Archives. The work has different objectives: to show the results that can be obtained, on an urban scale, thanks to a research path that compares indirect sources of different types with the observation of historical buildings; to highlight the “weight” and the role that the ties, often hidden, had in buildings, and not only the monumental ones; to increase knowledge of the production process of this constructive element. The wide and diversified use of metal ties found in Genoa seems to proceed in parallel, in the 15th century, with the development of a flourishing productive and mercantile business based on the commercial monopoly of the hematite of the island of Elba by the city oligarchy and, between the 16th and 17th centuries, with the huge investments in the construction sector highlighted by the abundant documentary sources. 相似文献

The aim of this study was to research transborder openness of companies in the divided city Zgorzelec/Görlitz on the Polish‐German border in the context of the advancement of integration processes on a local scale. The analysis has been done from the point of view of the everyday life of its inhabitants. Polish and German economic entities providing chosen services were researched. The study aimed to show the level of openness of these institutions to clients from the other side of the border. The integration of business landscapes may lead to the formation of a common public space and strong functional connections between two parts of the divided city. Analysis has shown a significantly varying level of openness of companies depending on the type of activity. Moreover, an asymmetry was observed in the scope of the influence of Polish and German business landscape. 相似文献
