A test aquarium containing water and waterlogged historical wooden material was observed during a three-year period at Vänernmuseum, Sweden, to test the feasibility of preserving and exhibiting archaeological wood or shipwrecks in a way accessible to the public. Experiments were also set up in a laboratory environment, to provide information on single factors that could influence the long-term preservation state of wood, and other processes that may occur in the water. 相似文献

AbstractThis article analyses Sonya Kelly’s How to Keep an Alien (Dublin Tiger Fringe, 2014) and ANU Production’s Vardo (Dublin Theatre Festival, 2014) in relationship to the performative backdrop of the Irish Decade of Centenaries (2012–22) and a series of key extra-theatrical political events have that featured asylum seekers and migrants prominently in Ireland and to a limited extent in Europe at large from 2012 to 2015. Both theatrical productions centrally engage tropes of Irish national memory vis-à-vis engagement with migration through a primary focus on women’s stories and premiered against the backdrop of the Decade of Centenaries. How to Keep an Alien and Vardo’s embrace of what M. Jacqui Alexander terms “palimpsestic time” and their critical focus on gender during this moment of the Decade of Centenaries models a theatrical dramaturgy that aids in reading key theatrical and extra-theatrical events featuring asylum seekers and migrants against one another. These works reveal the relationship between these events and the ongoing redefinition of Irish national memory and political community, a process thrown into sharp relief by the present commemorative mode. They insist that a turn to the past is inseparable from querying the lived political structures of the present, structures that have repeatedly displaced as well as instrumentalised the bodies of migrant women from the post-inward migration of the mid-1990s onwards. 相似文献

We explore the standards of research and reporting needed to justify the destructive analysis of archaeological human bone for biomolecular studies of ancient tuberculosis (TB). Acceptable standards in osteological interpretation have been met in some biomolecular papers, but there are also cases where insufficient care has been taken in distinguishing between pathognomonic lesions and those that are ‘consistent with’ a diagnosis of TB. Some biomolecular studies have failed to recognize that archaeological bones might be contaminated with environmental mycobacteria whose DNA could give rise to false positives in polymerase chain reactions directed at members of the Mycobacterium tuberculosis complex. The difficulties of applying spoligotyping to ancient DNA have also been underestimated and conclusions drawn from such analyses are often weakly supported. Assumptions that mycobacterial DNA preserves better than human DNA, and that contamination with modern DNA is less of a problem, has led in some cases to a laxity in research standards with insufficient attention paid to the need to authenticate ancient DNA results. We illustrate our concerns by reference to a recent paper reporting biomolecular detection of ancient TB DNA in skeletons from the eastern Mediterranean Neolithic settlement of Atlit-Yam. We are unconvinced that the skeletal evidence presented in this paper gives sufficient indication of TB to warrant destructive analysis, and we are concerned that during the biomolecular part of the project inadequate attention was paid to the possibility that results might be due to laboratory cross-contamination or to amplification of environmental mycobacterial DNA present in the bones. 相似文献

Central place foraging models are used to investigate assemblage variability at two Paleoarchaic (terminal Pleistocene/early Holocene) dacite quarries in the central and eastern Great Basin. Our analyses focus specifically on biface reduction and how varying degrees of reduction relate to the costs of transporting the resulting products upon departing the quarry. Our results suggest that when the distance to be traveled to a residential base is great, reduction will proceed further at the quarry than if the residential base is fairly close. Further, a residential site assemblage will consist of bifaces at later stages of reduction than its associated quarry. 相似文献
