Quantitative studies of relative dating parameters, including subsurface dolerite weathering rind thickness and weathering front penetration, permit the differentiation of three broad groupings of till deposits in several valleys in north-central, western, western-central and south-western Tasmania. An early cold climatic phase–the Linda Glacial Stage–is recognised on the basis of this weathering evidence which also indicates that there have been at least two more recent Glacial Stages of decreasing severity, termed here the Henty and Margaret Glacial Stages respectively. This three-fold model bears a striking similarity to that of Lewis (1945) which was rejected nearly three decades ago. However, whereas Lewis' model was founded upon erosional evidence, the present study is based entirely upon depositional and weathering evidence. 相似文献

With this paper, we address the culture of fear around youth violence in the US, and the way it is manifest in news media. We elaborate on the sexist, classist and racist biases in reporting and the ways violence is unequally commemorated and dismissed. We argue that place and, in particular, the myth of Middle America is a large player in selective memory. 相似文献
