Chang'an (now Xi'an) was the capital of the Western Han Dynasty and the starting point of the Silk Road. In the light of the importance of Chang'an as the centre of politics, economy and cultural interaction, the overarching question proposed in this paper is focused on its role in the mirror production and distribution network during Han period. On the basis of chemical and lead isotopic analyses of 34 Han mirrors, this paper discusses the potential existence of a mirror production centre in Chang'an. Meanwhile, a comparative study with mirrors uncovered from the south‐western frontier and from Central Asian and North‐East Asian countries offers new insight into these related issues. 相似文献

The governance of Antarctica has re-emerged as a geopolitical issue in the past decade due to the increased presence of China, India and Russia; the continent's importance in understanding global climate change; and its economic potential as a source of marine, genetic and mineral resources. This article examines the challenges for the Antarctic Treaty System (ATS) in this context and the consequences for Australia's foreign policy in its dual role as both a territorial claimant and supporter of ATS norms of cooperative science and environmental protection. The central argument is that Antarctic ‘bifocalism’ is under pressure as increased commercial activity and problematic jurisdictional interfaces with other regimes create difficult regulatory challenges for the ATS and encourage assertions of sovereignty that cannot be resolved within the existing regime. Consequently, the author argues that it is vitally important for Australia to preserve the legitimacy of the ATS through a policy framework of ‘strategic denial’ that aims to prevent all states from acquiring sovereignty over Antarctic territory. Australia should therefore reject recent proposals to securitise Antarctic policy or pursue World Heritage listing because they involve assertions of sovereignty that risk fracturing the ATS and thus compromise Australia's enduring interest in keeping Antarctica as ‘a continent of international cooperation and peace’. 相似文献

This paper examines the determinants of early school leaving (ESL) in a panel of 371 regions of OECD countries observed between 1998 and 2019. The empirical analysis includes both local factors previously emphasized by micro-economic studies and national-level factors such as education policies. We find that labor market opportunities for young people, as captured by the youth unemployment rate or the size of low-skill sectors, can pull students out of school. Conversely, late access to a large number of vocational education tracks, high preprimary enrollment and continuous training for teachers are strongly and negatively correlated with ESL rates. 相似文献
