Ground-edged artifacts were an important part of the Australian Aboriginal toolkit. They had practical day-to-day uses, but some had symbolic and social values that led to their movement across great distances. Australian provenance studies document long-distance Aboriginal exchange systems extending over hundreds of kilometers. The size and complexity of exchange systems and social networks were contingent upon resources and the productivity of a region's environment. Along the fertile, well-watered lands east of the Great Dividing Range, movement of objects may have been geographically more circumscribed than in drier areas to the west. One hundred and twenty-one mafic, ground-edged artifacts from the New South Wales (NSW) Central Coast and 368 geological specimens from potential sources were non-destructively analyzed by portable X-Ray fluorescence spectrometry. Results indicate the existence of a well-used basalt source within the region at Peats Ridge-Popran Creek as well as multiple local and non-local sources up to 430?km from Mangrove Mountain on the NSW Central Coast.  相似文献

Despite the amplitude with which Prime Minister W. M. Hughes voiced Australian claims during the First World War, his conduct in the immediate postwar years shows that his nationalism remained consistent with an imperial and British standpoint. This proposition is illustrated with reference to Hughes' role in the 1921 imperial conference, the Chanak crisis, and his post-prime ministerial memoir. While obsessed with expedients to improve the speed and scope of intra-imperial communications and thus facilitate consultation, Hughes was concerned to ensure that Australia played a proper role in arriving at a consensus on the deep common interest that unified Britain and the Dominions. His lack of concern for extending the scope for independent action won by the Dominions during the war, his dismissive remarks regarding the British role in the League of Nations, and the vehemence of his communications with London in 1922, must all be seen within the context of an imperial loyalty that survived the war undiminished.  相似文献

Abstract

Using complementary behavioural and population ecological models, we explore the role of production risk, normal surplus and inter-annual food storage in the adaptations of societies dependent on seasonal agriculture. We find that (a) household-level, risk-sensitive adaption to unpredictable environmental variation in annual agricultural yields is a sufficient explanation for the origins of normal agrarian surplus and, consequently, of household-level incentives for inter-annual food storage; and, (b) at the population level, density-dependent Malthusian processes tightly constrain the circumstances under which this same mechanism can be effective in smoothing inter-annual fluctuations in household food availability. Greater environmental variation and higher levels of fixed set-asides such as seed requirements or transfer obligations to political authorities lead to more severe, periodic famines; however, outside of famine events, these same factors improve average population welfare by suppressing population density to levels at which Malthusian constraints have lessened impact. The combination of behavioural and population ecological modelling methods has broad and complementary potential for illustrating the dynamic properties of complex, coupled human–natural systems.  相似文献

In recent years there has been increasing use of the term ‘empire’ to describe US primacy in world affairs. This should not be viewed merely as an indictment of US power: there are genuine insights to be gained from the study of imperial formations in contemporary politics. Yet there remains confusion and disagreement over the true meaning of ‘empire’. Progressive schools of thought in the academic discipline of international relations can facilitate a fresh understanding of ‘empire’—one that is suited to the complexities of the contemporary global scene.  相似文献

Rock art researchers throughout the world have explicitly or implicitly invoked ritual as an activity associated with the production of rock art but the articulation between the structure and composition of rock art assemblages and ritual behaviour remains poorly understood. Anthropologist, Roy Rappaport (1999) argued that all ritual, whatever the content or focus, has a universal structure. We review this proposition in the context of ritual studies and propose a method aimed at assessing the potential for identifying ritual structure in rock art assemblages. We discuss an archaeological analysis undertaken on the rock art assemblages in arid Central Australia, which aimed at distinguishing such a ritual structure among engraved assemblages, likely to have a Pleistocene origin, as well as more recent painted, stencilled and drawn assemblages. This analysis, despite its limitations, provides the foundation for developing a model, which will enhance the understanding of the relationship between the production of rock art and ritual.  相似文献

Sawankhalok, located in north central Thailand, was an early stoneware ceramic production site where the first kilns were dug cave-like into the natural ground, a method used in China for thousands of years. After a century or so, kilns at Sawankhalok began to be constructed of brick. It is suggested that if the bricks were pre-fired then an external influence may have been responsible. To the contrary, if raw unfired clay was used in the construction of the kilns the evolution was more likely a consequence of conceptual continuity.With the aid of chemical and mineralogical analyses it is shown that the kiln bricks were unfired at the time of kiln construction thereby suggesting that traditional conservatism, apparent in many aspects of the industry, caused processes to remain unaltered in the absence of a persuasive reason for change. These conclusions reflect on the degree of indigenous technology and artistic development associated with Sawankhalok ceramics as opposed to external influence.  相似文献

"A Nigerian case study illustrates how local understandings of health influence perceptions of infant survival in ways that may juxtapose indigenous interpretations to other 'objective' data. Evidence from two extended field investigations of a Hausa-Fulani village, set 12 years apart, suggests a decline in childhood mortality rates attendant upon the increasing availability of biomedicines. We note, however, that local perceptions are that mortality risks are now greater for those less than five years old. Our discussion focuses on the circumstances that inform this ethnodemography and its applicability to other population studies." (SUMMARY IN FRE)  相似文献
