In this paper I examine the development of a particular kind of grey stoneware called kamuiyaki which was produced and traded within the Ryukyu Islands, southwestern Japan, in the eleventh to fourteenth centuries. The wares themselves, their chronology, and archaeological context are discussed. The kilns represent the first enterprise in the islands in which a commodity was made for exchange on a substantial scale. The establishment of the kilns in a remote area, with technological borrowing from both Japan and Korea, reflects social and economic trends of the beginning of the Medieval Period in Japan. Greyware production, circulation, and consumption, reconstructed from recent excavations, shows a political economy capable of fostering the development of small states on the island of Okinawa in the thirteenth and fourteenth centuries.  相似文献

The quick and accurate identification of post-earthquake rescue objects can minimize the casualties and property loss caused by earthquakes. With the rapid development of remote sensing technology, rescue objects can be identified through high-resolution remote sensing images. There are two main categories of approaches to identify rescue object through high-resolution images: automatic extraction by a computer and visual judgment by professionals. Although results can be obtained quickly by using automatic extraction, the accuracy of the results is unacceptably low. For visual judgment, the large demands for time and professionals restrict its wide practical application. In this study, we introduce crowdsourcing into the identification of post-earthquake rescue objects. First, we integrate the advantages of the computer and crowdsourcing, which means that the computer takes advantage of the speed of information processing, while crowdsourcing makes full use of human recognition capabilities. Second, we take visual judgment tasks out of the hands of professionals and entrust the tasks to workers in a crowdsourcing platform. Not only are the human resources infinite, but we can also improve the efficiency of identifying rescue objects. Third, we propose a crowdsourcing model that improves the quality of the results and saves human resources. Finally, experimental results demonstrate that our solution is feasible.  相似文献

East Africa is home to a rich array of stone-tool traditions that span human prehistory. It is unsurprising, therefore, that the region attracted pioneer prehistorians in the early twentieth century, including L. S. B. Leakey, E. J. Wayland and T. P. O’Brien, who created the first cultural framework for East African prehistory during the 1930s. Although aspects of this framework remain relevant today, others have become misunderstood relics of an old classification system that hinders current research. This is particularly evident in the classification of a Later Stone Age (LSA) culture – the Kenya (East African) Aurignacian, later known as Kenya (East African) Capsian. Although this cultural entity was redressed during the 1970s and 1980s and redefined as the Eburran industry, there is still mystique surrounding the current status of the Kenya Capsian, its original scope and definition, the relationship with the Eburran and its position within a modern understanding of the East African LSA. This is largely due to paradigmatic shifts in researcher attitudes, leading to the use of the Eburran as a false proxy. It is necessary now to completely remove the term Kenya Capsian as an indication of similarity among the different LSA technologies. However, there also needs to be less emphasis on the importance of the Eburran and recognition that it is just one example of a multitude of diverse localised LSA industries. This will open the way for future research into the LSA and facilitate our greater understanding of recent prehistory in East Africa.  相似文献

This article considers the mid to late nineteenth-century world of the Fremantle Lunatic Asylum, Western Australia. By examining the built environment of the asylum and the uses of spaces within its walls, it is possible to understand not just the experiences of the inmates, but to highlight attitudes towards the insane. The asylum was built under authority of the British Government, and later transferred to the Western Australian Government’s care. Reflecting on this volume’s theme of colonial institutions, this article will highlight the effects of center and periphery relationships on life within the asylum.  相似文献

Navigation implies a deep knowledge of the environment in which it is practised as well as the development of correlated technologies and techniques. In fact, sailing in lakes, rivers, along coasts or in high seas requires specific skills. This is why watercraft reflect the specific expertise of cultures in relation to the available resources and materials. Navigation as a means of movement and boats as modes of transportation is a well-documented topic in Europe, Asia and the Pacific Ocean, whether focusing on antiquity or the present. Nonetheless, in the New World, especially in Mesoamerica where the Aztec, Tarascan and Mayan Empires flourished, indigenous maritime history has been thoroughly under-investigated. This article explores the first prehispanic dugout canoes of the region, based on a multidisciplinary approach for the Mexico and Pátzcuaro Basins, in the Late Postclassic period (AD 1325-1521). For the first time, a typology of these dugout types is proposed, with a discussion of the importance of dugout canoes as a means of transportation in Mesoamerican civilizations, where wheels and draught animals did not exist.  相似文献

Archaeologists often discuss the First People of the Western Hemisphere (the Americas) and their descendants, as Immigrants from Asia or Solutreans from France. In this paper, I discuss how archaeologists as handmaidens of the late modern state control the past in the present. This control keeps Indigenous people of the Western Hemisphere as recent migrants on a global history time scale. Arguing against recent initial migration time frames to the Western Hemisphere, I discuss the Indigenous Palaeolithic of the Americas; and what an acknowledgement of the ancient past may bring to contemporary Indigenous communities.  相似文献

Middle Egypt provides a unique insight into the organization of power, politics, economy, and culture at the turn of the third millennium BC. The apparently easy integration of this region into the reunified monarchy of king Mentuhotep II (2055–2004 BC) was possible because the interests and the local lineages of potentates were preserved. Trade and access and/or control of international exchange networks were important sources of wealth and power then. And Middle Egypt appears as a crossroads of diverse populations, as a hub of political and economic power, as a crucial node of exchanges through the Nile Valley, and as a power center whose rulers provided support to the monarchy in exchange of local autonomy and considerable political influence at the Court. In the new conditions of early second millennium, potentates from Middle Egypt succeeded in occupying a unique advantageous position, not matched elsewhere in Egypt, because of the concentration of wealth, trade routes, new technologies, political power, and autonomy in the territories they ruled.  相似文献
