Between 2005 and 2009 a deep‐water shipwreck was located, mapped, and partially excavated by a joint team from RPM Nautical Foundation and the office of the Soprintendenza del Mare, Sicily. Located off Levanzo Island, one of the Egadi Islands off north‐west Sicily, this wrecked merchantman revealed a mixed cargo of foodstuffs, coarseware, glass, and construction materials. The nature of the wreck‐site, its cargo, operational date, and find‐location indicate its likely association with the annona service which supplied Rome. © 2012 The Authors 相似文献

Since 2005, a burgeoning wave of Chinese investments has set off a new ‘minerals boom’ in the Australian iron ore and coal mining sectors. While normally a welcome development, the state-owned and strategic nature of the investors has raised concerns in Australia about how these should be regulated. As a result, in February 2008 the Australian government declared an intention to more closely screen foreign direct investment (FDI) from state-owned sources, which both supporters and detractors alike have claimed is evidence of ‘resource nationalism’ in Australia's approach towards its trade and investment relationships with China. This article challenges this understanding through an examination of the characteristics of Chinese mining FDI, the dilemmas these present to the Australian government, and the relatively restrained nature of its response. Through this, Australia's FDI policy is explained as a defensive move against the potential for strategic behaviour by Chinese investors resulting from their state ownership, rather than any national program to subject minerals trade and investment to political control. On this basis, the article argues that Australian government policy instead evidences a ‘resource liberalism’ approach, which intends to ensure that the governance of Australia's minerals trade and investment with China remain market-based processes. 相似文献

The thermoluminescence phenomenon has been used for pottery dating and radiation dosimetry for sixty years and for forty years
has been applied to the study of meteorites, being successful in quantifying metamorphic histories and providing new insights
into terrestrial age and orbits. Here we review some of the fundamental properties of thermoluminescence with particular focus
on the study of small extraterrestrial particles. We suggest that natural TL data can be used to identify the burial and release
history of cometary particles and that induced TL measurements can provide in-sights into the mineralogy of particles (even
when largely amorphous) and the metamorphic history of those particles. We illustrate the use of TL to study small particles
by describing recent studies on micrometeorites and 10–100 μm fragments taken from the matrix of a meteorite Semarkona which
is type 3.0 ordinary chondrite. 相似文献

Primary sources from the end of the Bronze Age have long been read as suggesting a time of chaotic transition, particularly with regard to threats from the sea that the established powers had no means of combatting. While the scale and severity of seaborne attacks seems to have increased in the late 13th century, these were not in themselves new phenomena, as a state of maritime threat seems to have been a constant for coastal polities and mariners in the Late Bronze Age eastern Mediterranean. However, a combination of internal and external factors in the late 13th and early 12th centuries combined to make these attacks more effective than they had been in the past, and polities more vulnerable to them. These included the rapid spread of improvements in maritime technology, particularly from the Aegean and the Levant, via high–intensity ‘zones of transference’, as well as an increase in the scale of ship–based combat operations, due in part to the displacement of people during the Late Bronze Age collapse. This paper addresses this in two parts, beginning with the ‘background’ evidence for a constant state of maritime threat in the centuries leading up to the end of the Bronze Age, and concluding with the ‘foreground’ evidence for zones of transference and the transmission of groundbreaking elements of naval technology in the years surrounding the Late Bronze–Early Iron Age transition. 相似文献
