A unique leaded‐gunmetal disc decorated with iconic Portuguese markings was recovered in 2014 during archaeological excavations at the Sodré shipwreck site in Al Hallaniyah, Oman. Initially the identity and function of the disc was unknown, although it did possess characteristics suggesting it could be an astrolabe. Laser imaging of the disc post conservation revealed regular scale marks on the limb of its upper right quadrant. Accurate digital measurements of the marks show them to be graded at close to 5‐degree intervals, thus confirming the identity of the disc as a mariner's astrolabe and the earliest known example discovered to date.  相似文献

Despite making modest progress on challenging management and security issues common to their shared border, the United States and Canada have, in recent years, slipped behind on advancing a progressive border agenda. The momentum unleashed under the 30-point Smart Border Action Plan, signed in late 2001, has slowed in the face of new regulations at the border, many of which were initiated by the United States. These include significant changes in US admission procedures under the Western Hemisphere Travel Initiative (WHTI), new border policing resources and protocols, as well as new customs and inspection fees. The much-heralded Security and Prosperity Partnership of North America (SPP), designed to facilitate both trade and security between the two countries, has also lost momentum, with the last trilateral meeting of leaders resulting in little more than a press release. As a result of these and other developments, it appears that rather than “thinning,” the US–Canada border is “thickening” at precisely the time when greater economic and security cooperation is necessary to bolster North American competitiveness in an increasingly globalized economy and complex security environment. This article will investigate some of the key reasons behind these policy developments, exploring some of the early positions that frame approaches to border management in the Obama administration. It will also offer some thoughts on opportunities for improved border management policies by providing some specific recommendations, which may help advance solutions to pressing – and festering – bilateral security and trade issues.  相似文献

This paper examines a group of Aboriginal bark-paintings featuring Macassan prau s that were collected in 1948 during the American-Australian Scientific Expedition to Arnhem Land. These paintings were studied in an effort to understand issues related to Aboriginal and Macassan cross-cultural interaction, stylistic adaptation and change, and maritime technologies. Furthermore it is one example in which the collaborative efforts of maritime and Indigenous archaeologies can achieve a more holistic technological and stylistic cross-analysis of watercraft imagery.

The intensification of fieldwork in northern Mesopotamia, the upper region of the Tigris-Euphrates basin, has revealed two cycles of expansion and reduction in social complexity between 4400 and 2000 BC. These cycles include developments in social inequality, political centralization, craft production and economic specialization, agropastoral land use, and urbanization. Contrary to earlier assessments, many of these developments proceeded independently from the polities in southern Mesopotamia, although not in isolation. This review considers recent data from excavations and surveys in northern Iraq, northeastern Syria, and southeastern Turkey with particular attention to how they are used to construct models of early urban polities.  相似文献

Recent geographical interventions have begun to question the power relations among lesbian, gay, bisexual and trans people, challenging assumptions that LGBT communities have homogeneous needs or are not characterised by hierarchies of power. Such interventions have included examinations of LGBT scenes as sites of exclusion for trans people. This article augments academic explorations of trans lives by focusing on ‘the gay capital’ of the UK, Brighton & Hove, a city that is notably absent from academic discussions of gay urbanities in the UK, despite its wider acclaim. The article draws upon Count Me In Too (CMIT), a participatory action research project that seeks to progress social change for LGBT people in Brighton & Hove. Rather than focusing on LGBT scenes, the article addresses broader experiences of the city, including those relating to the city as a political entity that seeks to be ‘LGBT inclusive’ and those relating to the geographies of medical ‘treatment’ that relocate trans people outside the boundaries of the city, specifically to the gender identity clinic at Charing Cross Hospital in London. It argues that trans lives are both excluded from and inextricably linked to geographical imaginings of the ‘gay capital’, including LGBT spaces, scenes and activism, such that complex sexual and gender solidarities are simultaneously created and contested. In this way, the article recognises the paradoxes of the hopes and solidarities that co-exist – and should be held in tension – with experiences of marginalisation.  相似文献

20世纪六七十年代,新西兰在英国回归欧洲并最终加入欧共体后陷入了严重的困境.由于没有充分认识到传统市场结构性断裂的不可逆转性,新西兰不仅未能及时从摆脱依附、变革自身经济方面寻求突破,更将主要的资源集中于围绕英国市场进行博弈,结果在传统市场变化、依附导致的产业结构失衡及石油危机打击下,陷入了较其他发达国家更为严重的综合性危机之中.  相似文献
