AbstractThe fourth-century B.C. was a period during which a large number of Greek cities were affected by civil wars, military conquests, and destruction, with the displacement of large numbers of men, women and children as a result. This has implications for the modern debate on Athenian attitudes to immigration, which normally focuses on just two groups of free non-citizens: adult, able-bodied men who moved to Athens voluntarily to take advantage of the city’s economic opportunities and (more recently) on the free non-citizen population who had come to Athens as slaves and who stayed on after their manumission. This article argues that refugees were likely to have constituted a considerable component of the migration to Athens during certain troubled periods in the course of the fourth century. This means that the size of Athens’s immigrant population was likely to have fluctuated considerably, that many of the refugees would have been destitute, that women and children (sometimes unaccompanied by adult male relatives) may have made up an even greater proportion of the non-citizen population than normally assumed, and, thus, that a considerable number of these immigrants would not have been able to contribute substantially to Athens’s grain trade or military. The implications of this for our assessment of the Athenian motives for admitting groups of refugees are discussed, and it is argued that the requirement that all male and all unaccompanied female immigrants had to find an Athenian sponsor and pay a special metic tax may have constituted a certain level of control over immigrant numbers. 相似文献

During the past decade research into the German Final Paleolithic and Mesolithic has experienced an important revival. One clear sign of this renewed interest in the periods are the annual meetings of the Arbeitsgruppe Mesolithikum (Mesolithic Working Group) which have taken place every spring since 1992. At these meetings, which take place at changing venues, topical themes of Final Paleolithic and Mesolithic interest are presented by informal lectures and it is also possible to study regional collections (artifacts, raw materials) at first hand. Numerous contributions were subsequently published together in one volume (Conard and Kind (1998) Aktuelle Forschungen zum Mesolithikum/Current Mesolithic Research, Mo Vince, Tübingen). The present paper intends to complement that collection of papers with a synthesis of developments and perspectives and to present recent research highlights in the German Final Paleolithic and Mesolithic, together with a comprehensive bibliography, to a wider international audience. 相似文献

Knowledge intensive business services (KIBS) are believed to be one of the main drivers of technological change, innovation, and economic progress. Although firm foundations play a crucial role among KIBS, entrepreneurship research has hardly ever investigated the sector. As firm founders in early stages of their firms' development mostly draw on regional resources, and as the provision of the services is an interactive process, “proximity” between the different actors of the particular territorial innovation and production system clearly matters. This contribution analyses the interrelationships between KIBS foundations and their respective innovation and production systems by performing qualitative and conceptual in-depth studies of three German metropolitan regions. 相似文献

The violence of spectacle: Statist schemes to green the desert and constructing Astana and Ashgabat as urban oases 总被引:1,自引:0,他引:1

Kazakhstan and Turkmenistan have been home to the most impressive urban development projects in the entire post-Soviet world. Their capitals, Astana and Ashgabat, now boast uniquely monumental architecture and local leaders have invested heavily in ‘green belt’ projects to surround the cities with lush vegetation, as well as developing green and water-laden public spaces. In doing so, elites have drawn on Soviet-era ‘garden city’ idealism, as well as more recent environmental sustainability narratives. Yet these schemes are anything but sustainable. Unfolding on the arid Central Asian steppe, they depend on heavy irrigation, with water diverted from rivers that already fail to meet regional demands. Employing a comparative approach, I ask why and with what effect state planners have sought to craft Astana and Ashgabat as spectacularly green ‘urban oases,’ when their local climates should defy the logic of sustainability. In so doing, I consider urban greening in the two countries as part of a wider phenomenon of statist schemes to green the desert, which have a long and diverse history. Extending the literature on desert greening, I argue that the structural violence they manifest and perpetuate is best understood by attending to how they operate as a form of spectacle. 相似文献

ABSTRACTEvaluating the rate of deterioration at archaeological sites in the Arctic presents several challenges. In West Greenland, for example, increasing soil temperatures, perennial thaws, coastal erosion, storm surges, changing microbial communities, and pioneer plant species are observed as increasingly detrimental to the survival of organic archaeological deposits found scattered along the country’s littoral zones and extensive inner fjord systems. This article discusses recent efforts by the REMAINS of Greenland project for developing a standardised protocol that defines the archaeological state of preservation, the preservation conditions, and asset value of organic deposits. Special emphasis is given to the degradation of materials such as bone and wood that are historically observed to be well-preserved in Greenland but now currently at risk. The protocol provides a baseline for monitoring future changes and will assist archaeologists in Greenland with a procedure for documenting and predicting areas of increasing vulnerability due to a warming climate. 相似文献

Birch tar was the first adhesive produced by humans. Its study has consequences for our understanding of human evolution and the development of specialised craftsmanship. One of the better-documented birch tar making methods is the ‘double-pot’ technique, where two containers are used, one containing bark, the other collecting the tar. Birch tar made with double-pots has low viscosity and bad adhesive properties. To obtain a usable adhesive, it must be reduced in volume by cooking. We investigate the evolution of tar’s mechanical properties during cooking. We use lap-shear tests to investigate strength, stiffness and failure behaviour. We found that tar must be cooked for 90 min to acquire adhesive properties. When cooked for longer, strength and stiffness increase over a 30 min lasting time span. Cooking for even longer, beyond this 30 min window, produced a substance that could no longer be used as an adhesive. The implications are that tar cooking requires a high level of skill because specific signs indicating the desired properties must be recognised during the process. Tar cooking constitutes a supplementary investment in time and resources and appears to be associated with a certain degree of risk. 相似文献

ALOS/PALSAR L-band full polarimetric data have been used to detect and characterize a well-defined geometric target hidden under sand deposits in the Western Desert of Egypt. This buried object is rectangular in shape with very straight boundaries and encloses an area of 500 m2. Inside the rectangular area there is a perfectly circular feature of approximately 53 m2 area. High and medium resolution optical satellite images (WorldView-2, ALOS/AVNIR-2) and field investigation confirm that the topography of the study area is relatively flat and completely covered by dry sand. The electromagnetic wave scattering behavior of the detected buried object was measured by decomposing the scattering matrix of ALOS/PALSAR full polarimetric data into Entropy-Alpha (H/α) and Freeman and Durden decompositions. Furthermore, a combination of unsupervised classification algorithms and Constant False-Alarm Rate (CFAR) edge detection was performed on the polarimetric data which revealed a well-defined geometric shape with straight borders. These borders have high α angles with low entropy, which physically means double bounce scattering mechanism with low randomness and is very similar to that of an urban scatterer, indicating that the detected target might be a buried wall-like foundation of a man-made structure. Moreover, 28 ground penetrating radar (GPR) profiles were acquired using a 270 MHz shielded antenna to validate the satellite radar remote sensing results. The GPR profiles reveal very clear hyperbolic shapes at 1.5 m depth with one of them showing a large hyperbolic shape-like structure, which might indicate the presence of a buried foundation. Thus the site might have significance to archaeological studies of the Western Desert, particularly previous human occupation and the sources of water for such habitation. 相似文献
