Preservation in situ and the monitoring of archaeological sites have become important themes since the acceptance and implementation of the Valletta Treaty. In the last few decades, our knowledge of degradation processes has increased manyfold, and a range of techniques have been tested and applied for use in both assessment and monitoring. Despite these successes, all is not well. First, we have little notion of the speed of the decay processes involved. This makes it difficult to distinguish between acute and protracted degradation. Apart from that, many assessments and subsequent monitoring projects rely (too?) heavily on complex and costly specialist technology. For any future preservation — in situ — projects low-tech observations together with best estimates of decay rates and archaeological site information should be combined to make an accurate assessment of the effects of decay on the archaeological record. Monitoring for preservation purposes is only appropriate if (1) decay processes occur within a relevant and measurable time scale, and (2) if mitigating actions can be taken or preservation ex situ can be performed (i.e. a rescue excavation) if significant degradation takes place.  相似文献

In southwestern Louisiana, the public sphere is dominated by the image of the Cajuns, presented as a hardy, likable people who have overcome significant obstacles since their arrival as Acadians in the late eighteenth century. Across the cultural region designated “Acadiana,” which comprises 22 counties, nearly 30% of the population is black (or Creole, mixed-race peoples generally identifying as black). Contributions of non-whites to the region’s history are usually not incorporated into the public historical narrative, and the erasure of these groups’ influences on the state’s cultural “gumbo” has profound symbolic and material consequences. Black/Creole residents note that much of their culture – primarily music and foodways – has been repackaged as Cajun or subsumed under the Cajun label and that they are unable to take advantage of the benefits that Creole-oriented tourism could bring to a region in which half of the counties are designated “black high poverty parishes.” Using mixed methods, including interviews, archival analysis, and census data, this paper explores the social, political, and economic consequences of the domination of Cajuns in the south Louisiana memorial and representational landscape and argues that commemorative silences in what Alderman et al. have called the “memorial arena” perpetuate a hegemonic social order.  相似文献

In May 1985, two years after he had returned to the back benches, Francis Pym launched the first organised display of dissent within the parliamentary Conservative Party against Margaret Thatcher's leadership: Conservative Centre Forward. Those Conservative MPs who joined the group were very much believers in One Nation Conservatism. Conservative Centre Forward survived for barely a week after going public; it rapidly collapsed amid accusations of disloyalty and inept leadership. The group proved to be a short-lived experiment which achieved little of note and exposed those who were involved to widespread ridicule. Yet, it was precisely because Conservative Centre Forward collapsed so quickly and achieved so little that it was significant. In its own way, the short life of the group provided a revealing commentary upon the character of the mid-1980s Conservative Party. It was a party which, on the one hand, was moving inexorably to the right and therefore ever further away from the values of One Nation Conservatism which Conservative Centre Forward espoused. On the other hand, it was a party which was still traditional enough to view open displays of dissent, of whatever magnitude, as a threat to the unity upon which its continued electoral success depended.  相似文献
