We report the results of a test excavation of deposits in a limestone cave sub-chamber located beneath the main chamber of Liang Bua, Flores, Indonesia; the discovery site of the small hominin species, Homo floresiensis. Well-preserved remains of extinct Pleistocene fauna and stone artefacts have previously been identified on the surface of a sediment cone within the sub-chamber. Our excavation of the deposits, at the base of the sediment cone in the sub-chamber (to 130 cm depth) yielded only a few fragmentary bones of extant fauna. Uranium/Thorium (U-series or U/Th) dating of soda straw stalactites excavated from 20 to 130 cm in depth demonstrates that the excavated sediments were deposited during the Holocene. Red Thermoluminescence (TL) dating of the sediments at the base of the excavation (130 cm depth) indicates these sediments were last exposed to sunlight at 84 ± 15 ka (thousand years), similar to red TL ages of cave sediments from the main chamber. Together, these results indicate that the surface faunal remains, which are morphologically analogous to Pleistocene finds from the main chamber excavations, were transported to the sub-chamber relatively recently from the main chamber of Liang Bua and probably originated from conglomerate deposits at the rear of the cave and from deposits around the front entrance. There is no evidence for hominin occupation of the sub-chamber, instead it seems to have acted as a sink for cultural materials and fossil remains transported from the surface via sinkholes. Despite the small number of finds from the test excavation, it is possible that more extensive excavations may yield additional transported cultural and faunal evidence at greater depths. 相似文献

Abstract: In 2001, President Bush announced his intention to “end chronic homeless by the year 2012” as part of his broad “Compassion Agenda”. Since then, departmental consolidation, changes in funding allocation, and continued decentralization of services provision have dramatically reshaped the landscape of homeless service provision in the US. In this paper I examine how these roll‐out policies reify and re‐entrench liberal equations of property with rational self‐governance at the local scale. Particularly, I illustrate how tropes of homeless otherness work alongside and through federal neoliberal roll‐out policies to exclude homeless voices from the formation of local social policy. In doing so, I attempt to call attention to the mutually constitutive relationship between the spatial management of homeless bodies, tropes of homeless deviance and dependence, and limits to citizenship in the context of neoliberal urban governance. 相似文献

Lead concentrations were determined in ribs obtained from the Neolithic long barrow at Hazelton and compared with those in a series of modern bones. The mean lead concentration in the neolithic material was about two-and-a-half times less than the contemporary mean indicating that human activity has considerably increased the human body burden of lead. 相似文献

This article explores the nature, tactics and effectiveness of the vocal anti-Vietnam war movement in Britain. It focuses on the rhetoric and actions of a range of different groups, from the far-Left Vietnam Solidarity Campaign, to the broad-Left British Council for Peace in Vietnam and the labour movement. It asks how far the anti-war opposition was able to shape both government policy and public debate on the war, and positions the British opposition within its wider global anti-war context. It explores the meanings of solidarity (with the American, or global, anti-war movement or with the North Vietnamese) for the British movement, and it highlights the ultimately domestic focus of the campaign. 相似文献
