Sections of human hair from naturally desiccated Sudanese Nubian mummies representing X-Group (AD 350-550) and Christian (AD 550-1300) periods in the Wadi Halfa area have been analysed for their isotope ratios. Because the carbon in hair represents food intake over the growth period of this tissue, analysis comparing segments taken next to the scalp with those further along the shaft can indicate diet just prior to death as well as any recent shift in food consumption. Modern populations in this area practise seasonal crop scheduling which involves the cultivation of C3 plants (wheat, barley and most fruits and vegetables) in the winter and the hardier C4 plants (sorghum and millet) in the summer. Shifting isotopic values along the length of hair strands of the ancient inhabitants of this area demonstrate that this practice has its roots at least as far back as the Initial Phase of Intensive Agriculture. The most common season of death appears to have been summer, the time of greatest climatic, nutritional and physiological stress for both ancient and modern inhabitants.  相似文献

The federal organisation of government in Australia is one of the least understood aspects of the Australian political system. Despite the durability of federal structures, federal theory in Australia remains largely underdeveloped. Aside from a few scholars who have persistently analysed the federal process, federalism in Australia has received attention as an outmoded system with little scope for distinguishing the benefits to be gained from understanding how government is organised. But where Australian federal theory has languished, American federal theory has flourished. This paper borrows some of the major ideas which have influenced analyses of government functions in the American ‘ system and posits them against analyses of Commonwealth and State government functions in Australia.  相似文献

We extend the impact decomposition proposed by LeSage and Thomas-Agnan (2015) in the spatial interaction model to a more general framework, where the sets of origins and destinations can be different, and where the relevant attributes characterizing the origins do not coincide with those of the destinations. These extensions result in three flow data configurations which we study extensively: the square, the rectangular, and the noncartesian cases. We propose numerical simplifications to compute the impacts, avoiding the inversion of a large filter matrix. These simplifications considerably reduce computation time; they can also be useful for prediction. Furthermore, we define local measures for the intra, origin, destination and network effects. Interestingly, these local measures can be aggregated at different levels of analysis. Finally, we illustrate our methodology in a case study using remittance flows all over the world.  相似文献

From a theoretical perspective, it is possible to enhance the innovation of firms and institutions by combining the analytic (scientific) knowledge base of research and development (R&D) institutions with the synthetic (practical) knowledge base of industries. Such combinations of knowledge are also believed to support regional development. One such initiative to bridge knowledge from the R&D sector and industry is the Norwegian Centre for Offshore Wind Energy (NORCOWE). However, as our case study shows, it is hard to bridge knowledge from these two partner groups. We found that this is mainly because of differences in the partners' timelines (long versus short), their attitudes toward knowledge (research based versus experience based), application of the knowledge (knowledge per se versus commercialization), and organizational dimensions (linear/closed process versus interactive/open process). These differences show that the knowledge bases of these two groups may not just be different; they can also be seen as discrepant. We also argue that the NORCOWE initiative is influenced by a “policy push” logic. This implies that the initiative was not properly embedded in the industrial or R&D institutions before being launched, but was instead driven by a political will to promote the development of a new renewable energy source.  相似文献

This article extends Billig's (1995) landmark thesis on banal nationalism by considering how processes of national deixis circumscribe the boundaries of citizenship and forms of belonging within nation-states. Drawing on critical analyses of sexual citizenship, the article provides a discursive analysis of the debate over civil union in the New Zealand mainstream press during 2004–2005. It argues that this mediated debate represented an historical moment where the routine deictic flagging of the nation, and the correlated flagging of the ‘banal citizen’, fundamentally broke down, thereby allowing this unmarked and ‘ordinary’ process to be systematically examined. Four major discourses are identified in press coverage: ‘Homosexual’ subjects as abnormal and disordered, tolerance, equality and human rights, the sanctity of marriage and the preservation of the family (and the social order). Although the passing of the Civil Union Act does mark a (faltering) step forward in sexual equality, we argue that the presence of these discourses suggests that forms of both ontological and cultural heterosexism persist in New Zealand society. Despite the Act conferring new legal rights, ultimately we conclude that the four discourses act to restrict the extent to which ‘homosexual’ subjects are considered ‘valid’ and ‘legitimate’ citizens. In continuing to structure the public politics of sexual citizenship in New Zealand, these discourses have influenced recent debates over legislative moves towards ‘marriage equality’ in ways that raise concerns over the continuation of heterosexist norms, as well as exclusionary forms of homo-nationalism. More generally, this research demonstrates the effectiveness of Billig's work as a valuable and productive analytic lens to explicate concerns over the exclusionary nature of citizenship itself.  相似文献

New Zealand is valuable as an extreme case in agricultural trade liberalisation and in market-oriented national biosecurity policy, for exploring the causes-of-effects of economic interests on national biosecurity policy. The article argues that the state is the best advocate of agro-economic interests and that international negotiations on trade liberalisation played a decisive role in the protectionist and economic orientation of New Zealand's biosecurity policies. The study contributes to improving theoretical work on the relationship between international cooperation and domestic reform politics. It suggests a historical-institutionalist and dynamic perspective which incorporates the role of institutionalised vested interests and effect of timing and sequencing. This perspective helps to explain why states' policy preferences originate from economic interests and why patterns of interaction between international and national processes have such a strong effect.

新西兰作为农业贸易自由化以及市场导向的 生物安全政策的一个极端案例,对探讨经济利益与国家生物安全政策的因果联系,是非常有价值的。作者认为,政府是农业经济利益的最佳辩护师,贸易自由化的国际协商对于新西兰生物安全政策的保护主义及经济的取向起了决定性作用。本研究致力于完善有关国际合作及国内改革政策之间关系的理论探讨。本文建议采用一种历史—制度主义以及动态的视角,将制度化的既得利益以及时间、时序的作用纳入视野。这样一种视角有助于解释为什么政府的政策倾向源自经济利益,为什么国际过程与国家过程的互动模式会有如此强烈的效果。  相似文献

Many connections have been made between the Great Depression and the current crisis in neoliberal capitalism, and many solutions proposed by the Left hearken to FDR’s New Deal programs. While New Deal policies had real benefits, assuming that they were uniformly beneficial to all lower class individuals is shortsighted. This is clear from the vantage point of our research in the Finger Lakes National Forest. The New Deal’s Resettlement Administration purchased these farms when implementing land-planning policies to move farmers off “sub-marginal” land to save families “stranded on sub-marginal farms.” Our research demonstrates that governmental land-use programs saved some farms by sacrificing others. This case makes it clear that solving current crises need more than nostalgic yearning for a mythic past. Solutions must come from a thorough examination of the “real concrete” past, not simply the past as imagined.  相似文献
