Resistance to British control of Ireland’s maritime landscape under the United Kingdom of Great Britain and Ireland (1800–1922) was highly localized, enacted in part through Irish choices in boat construction and patterns of movement at sea. British naval authorities overseeing Achill Island in County Mayo used both coercive and conciliatory means to replace Irish subsistence fishing from regional vernacular boats with commercial fishing from larger non-local vessels reliant upon piers and dredged harbors. These changes encouraged islanders’ dependency upon imported food and wage-based employment performed under Protestant surveillance. Indigenous boats including curraghs and yawls played central roles in Irish resistance to these changes, through the assertion of traditional lifeways and practices. 相似文献

An assessment of the luminescence sensitivity of Australian quartz with respect to sediment history 总被引:2,自引:0,他引:2
Kathryn E. Fitzsimmons 《Geochronometria》2011,38(3):199-208
This study provides a preliminary systematic characterisation of OSL sensitivity, with respect to sediment history, of single
grains of Australian quartz from a variety of source rocks and depositional contexts. Samples from two distinct lithologies
and with relatively short modern sedimentary histories were compared in an examination of the influence of rock type on OSL
sensitivity. Sediments derived from weathered sandstone were found to be brighter than those from metamorphosed schists, suggesting
that sensitivity may be inherited from the source rock and its earlier sedimentary history. Secondly, quartz from the same
source, but different modes of deposition, was compared to assess the effect on sensitivity of nature of exposure to light
during the most recent bleaching event. Quartz grain sensitivity appears not to vary depending on the mode of sediment deposition,
suggesting that the nature of exposure to light during deposition is less important in the sensitisation process. This study
highlights the complexity and variety of natural sedimentary quartz, demonstrating the limitations of an investigation based
solely on OSL sensitivity. Further systematic investigation into the physical, geological and geomorphological characteristics
of sediments is proposed to better understand the mechanisms of luminescence sensitisation in quartz. 相似文献

Stone tools were knapped, not built. This truism means that tools were reduced from larger pieces in the production process. But many tools were further reduced in use, to repair damage or as edges dulled. Reduction reduced size (trivially), but also changed the proportions among tools' elements or dimensions. Such allometric variation (change in proportion as a function of change in size) is useful to estimate the degree of reduction that tools experienced. Reduction itself is a measure of curation, a theoretical concept of great interest in lithic studies and Paleolithic archaeology. To determine the reduction that archaeological tools experienced, we must compare their size and proportions at first use to the same properties at discard that we directly measure. By now many size estimates can be made from discarded tools. Some are experimentally tested but few are validated using direct ethnoarchaeological controls. We validate two allometric reduction measures—ratios of plan area to thickness and of an estimate of original to discarded volume—against direct measures of use and reduction in ethnographic Gamo hidescrapers from Ethiopia. 相似文献

Considered one of the world’s earliest examples of a pristine state, the ancient Egyptian state arose by ca. 3000 BC. State formation in Egypt became a focus of much research in the 1970s and 1980s, as investigations of the Predynastic period in Egypt, when complex society arose there, began to uncover new evidence of the indigenous roots of this phenomenon. More recently, archaeological investigations in the Delta as well as continued work in southern Egypt have provided new evidence for the changes that took place in the fourth millennium BC. But the specific events and processes involved in this major sociopolitical and economic transformation and the resultant state still remain incompletely understood. To better understand the problem in Egypt, this study looks at the contrasting polities in fourth millennium BC Egypt and Nubia from the perspective of the political economy and the strategies to power proposed by the dual-processual theory, which also helps elucidate processes of state formation and the type of early state that developed there. The territorial expansionist model helps explain where and when this state first emerged. 相似文献

Employing and extending Hans-Jörg Rheinberger's analytical concept of epistemic things, this essay proposes one reason why squid giant axons, unusually large invertebrate nerve fibers, had such great impacts on twentieth-century neurobiology. The 1930s characterizations of these axons by John Zachary Young reshaped prevailing assumptions about nerve cells as epistemic things, I argue. Specifically, Young's preparations of these axons, which consisted of fibers attached to laboratory technologies, highlighted similarities between giant axons and more familiar ones via lines of comparative study common to aquatic biology. Young's work convinced other biologists that the squid giant fibers were, in fact, axons, despite their unusual fused (syncytial) structures, thereby promoting further studies, such as intracellular measurements, made possible by the fiber's size. Tracing direct relations between preparations of squid axons and broader interpretations of neurons as epistemic things, this paper renders an actors’ category, “preparations,” into an analytical one. In turn, it offers glimpses into how aquatic organisms shaped twentieth-century neurobiology and how local experiments can drive broader, disciplinary changes. 相似文献

National sentiments have historically overwhelmed global ones in the modern era. Archaeology was born in the service of the nation-state, as a technical means for engaging with the past within a specific calculus of territory, sovereignty, and nationhood. Significant shifts are currently underway, however, towards transnational modes and mechanisms of governance that have arisen in the wake of international dysfunction and neoliberal reforms. Within this emerging field of action it is development, rather than conservation, that shapes the diverse work of archaeological practice in the world. Transnational sociopolitical contexts for archaeological practice most visibly gained traction with multilateral development banks’ turn to heritage development in the 1990s, built around the tenets of participation, capacity-building, and sustainability. From these roots a second generation of concerns has emerged—transnational communities, heritage rights, and global climate change—for archaeological practice attuned to a “politics of engagement” (Mullins 2011) in a transnational key. 相似文献

During the first four decades of the 19th century carrier services in the northeast of Scotland developed rapidly. Most were centred on Aberdeen, the main city and port of the region, but local networks also existed, focused on other towns in the region. Improved road facilities throughout the region, particularly those formed by turnpike trusts, enabled an increasing number of locations to be served in this way. The rapid economic development that took place in the area at this time led to, and was fostered by, an increasing frequency of service.. The arrival of the railway in the region in the middle of the 19th century, and its gradual extension north and west of Aberdeen, had a major effect on the road‐based carrier network. Long‐distance routes centred on Aberdeen declined rapidly, there was rationalisation within the services provided, new services grew up centred on railway facilities, and the number of short‐distance carriers increased. The flexibility inherent in carrier services, however, ensured that they continued to remain relevant to customers in the 20th century. 相似文献
