Earth scientists are often asked to establish or constrain the likely provenance of very small quantities of earth-related material as part of a forensic investigation. We tested the independent and collective interpretations of four experts with differing analytical skills in the prediction of sample provenance for three samples from different environmental settings. The methods used were X-ray diffraction, scanning electron microscopy, the assessment of pollen assemblages, and structural characterization of organic matter at the molecular level. Independent interpretations were less accurate than those where multiple techniques were combined. Collective interpretation was very effective in the assessment of provenance for two of the three sites where the mineralogy and plant communities were distinctive. At the other site, although the mineralogical analysis correctly identified the Triassic mudstone soil parent material, Carboniferous spores from domestic coal were initially interpreted as deriving directly from bedrock. Such an interpretation could be a common pitfall owing to anthropogenic redistribution of material such as coal. 相似文献
Economic investment and the growing immigration of Han Chinese from other parts of China to the Xinjiang Uyghur Autonomous Region over the last three decades have increased the presence of eastern Chinese architecture in the urban built environment. This paper refers to the making of, residing in and speaking about the materiality of urban architecture by Turkic-speaking Muslim Uyghur middle-class actors. Besides creating personal comfort through Uyghur elements they draw ethnic boundaries to the Han Chinese. In highlighting the materiality of architecture, the analysis expands beyond the individual house by investigating the ways in which urban architecture offers spaces of meaning for social and ethnic communities. Based on ethnographic data, this paper argues that due to the political context and the state-controlled urban development with Chinese characteristics, urban Uyghur architecture was relegated from the outside of houses to an emphasis on interior decoration. 相似文献
Australian scholars are now familiar with the tropes of the Anzac legend. This narrative describes the realisation of an Australian masculine identity, whose characteristics were forged on the Australian frontier and validated through the ordeal of battle. Though many writers contributed to this narrative, C.E.W. Bean, the official historian of the Australian Imperial Force during the First World War, is most closely associated with the popularisation of this myth, which fused frontier and martial masculinity into a national archetype.
This article will examine the role of the slouch hat as a material and visual device that helped communicate the Anzac legend. While most of the scholarship that examines the construction of this narrative focuses on its articulation in prose, this narrative was also popularised through other media. Artists drew symbols of the frontier into their paintings while museum directors arranged their artefacts to support this narrative. This article will argue that the slouch hat provided an essential visual device to connect the narratives of frontier and martial masculinity through the image of the Australian soldier. 相似文献
