ABSTRACTThis paper employs δ13C and δ15N analysis of bone collagen to explore animal management at large Norse settlement sites in the liminal environments of the Scottish North Atlantic Islands. The Norse period was a time of social, cultural and economic change; the need to feed an expanding population and the demand for trade meant that domestic stock were a crucial resource. Our results indicate that rearing animals in these challenging insular environments required careful management. At all sites, the diet and movement of domestic cattle and sheep were highly similar and carefully controlled and, despite many of the analysed settlements lying close to the coast, there was no use of shorefront grazing or fodder resources. In contrast, pig rearing strategies varied across the island groups. In the Western Isles pig diets were diverse, indicative of household or ad hoc management, whilst on Orkney all pigs consumed a more restricted diet based primarily on terrestrial protein. A comparison of red deer with domestic stock on the Western Isles indicates that both groups were exploiting similar grazing niches. 相似文献

Measuring the pace of cultural change, and understanding its determinants is a fundamental goal of anthropological research. The archaeological record is the main source of information about the pace of cultural change, but it is an imperfect one, as taphonomic loss and mixing distort rate measurements. Here, I focus on the impact of time-averaging on rate measurements. Time-averaging arises when archaeological materials associated with activities and events that took place at different points in time are mixed into the same unit, whether because of depositional processes, disturbance factors, or because archaeologists lump together archaeological contexts when creating analytical units. I use analytical models to show how time-averaging can slow down the observed rates of change under two general modes of cultural change: random drift and directional change. I test this prediction using empirical rates of change from the archaeological record of North America. I show that empirical rates of change are indeed inversely correlated with the duration of time-averaging and provide a range estimate for this correlation. 相似文献

In Australia, e-government is continuously re-defining service boundaries. While this may be good in the case of transactional interactions, for example the online submission of tax returns, it is less clear that interpersonal services, such as working closely with the long-term unemployed, are best delivered digitally. We consider the impact of social services digitisation on vulnerable communities drawing on an analysis of remote Aboriginal communities. Digital uptake affords great opportunities, but it also carries risks. Some communities have no digital infrastructure and in certain cases traditional face-to-face services have been curtailed, leaving those not online with reduced assistance. We find that concerns about the ‘digital divide’ are well founded. Problems generated by e-government flow across boundaries and appear left to the third sector to resolve with the state playing an even more diminished role in the lives of disadvantaged citizens. 相似文献

This symposium draws attention to innovative and emerging research in Australian public policy exploring the interplay of governance, public policy and boundary-making. Conceptually and substantively, boundaries are fundamental to understanding policy outcomes, yet remain overlooked and undertheorised. We aim to contribute to public policy debates, in Australia and beyond, by provoking further reflection on this theme, in particular, the distributive effects of boundaries in policy-making; the blurring of boundaries implicit to governance frameworks; the crossing of boundaries, especially by policy-officials within and between institutions; the construction of boundaries to separate and marginalise; and the existence of temporal–spatial boundaries that demarcate jurisdiction and authority. In short, the study of governance and public policy-making is marked by multiple different types of boundaries but the way in which boundaries get drawn and redrawn is also suffuse with political contestation meaning they raise crucial questions about the exercise of power. 相似文献

ABSTRACTAmongst Britain's former colonies the independent countries of the Commonwealth Caribbean represent something of an anomaly in so far as the majority of them remain constitutional monarchies and continue to retain the Judicial Committee of the Privy Council (JCPC) as their final appellate court, even though the region has had its own final appellate court – the Caribbean Court of Justice – since 2006. This is in marked contrast to Britain's former colonies in Africa and South Asia, the majority of which switched to republicanism soon after independence and at the same time abolished rights of appeal to the JCPC. This paper seeks to uncover the reasons for this anomaly by examining how the path that led to independence was shaped by a particular conception of Dominion status and by the willingness of nationalist leaders to embrace a dual identity: equal parts West Indian nationalist and Empire loyalist. It will also examine the phenomenon of the ‘postcolony’; being the persistence of the colonial order following the acquisition of constitutional independence. The paper has three aims. Firstly, to contribute to a better understanding of the impact of Dominion status and all that it symbolised in a region which is often overlooked in the scholarly literature on this topic. Secondly, better to understand the competing political forces that led three countries in the region to adopt republicanism, but inhibited its adoption elsewhere in the region. Thirdly, and finally, to enhance discussion of the complex nexus between republicanism and the abolition of rights of appeal to the JCPC where political and juridical considerations do not neatly align. 相似文献

There is much evidence for the parliamentary organisation of the whig junto in Queen Anne's reign, but little for its extra‐parliamentary organisation. This note gives evidence for such extra‐parliamentary organisation late in the reign of William III from letters by both James Vernon and Robert Harley, which describe meetings of the junto and some of its supporters in the country houses of followers in the summers of 1698, 1699 and 1700. 相似文献

The Hui-style residence is an important architectural heritage of China. The hollow wall structures are widely used to build its exterior wall system. However, the thermal performance of the hollow wall is no longer able to meet the new energy-saving and environmental requirement. This article describes a laboratory study of the development of foamed mortar (FM), with the potential for use in thermal upgrading of the Hui-style hollow wall system without dramatically changing its traditional structure. The key early age, physical, mechanical and thermal properties were systematically measured. Two extended models were respectively developed to calculate compressive strength and thermal conductivity, as a function of porosity. Environment chamber test was also employed to investigate the effectiveness of this novel thermal upgrading approach and the results show that filling the voids with FM can effectively improve the overall thermal resistance of the hollow wall system by 44%, which is almost equal to the overall thermal resistance when using the more expensive commercial inorganic stucco system. In addition, the combination of these two methods yielded an overall thermal resistance of 0.701 m2·K/W, which is even higher than 0.67 m2·K/W for the code required in the hot summer/cold winter climate zone. 相似文献
