Foreign supply to Russia in the First World War is familiar terrain, but although the present paper engages to some degree with the military, diplomatic, and especially economic aspects of the subject, its primary affiliations lie elsewhere. Its principal purpose is to discuss the icebreakers on which it concentrates not only just before but also just after Russia's withdrawal from the First World War, with a view to contrasting the first phase of the ships' history with the second and so highlighting the perennially ambivalent character of the Anglo-Russian relationship. On the way, it touches on questions of geography, English local history, environmental history, the history of technology, and, even, towards the end, Russian literary history. 相似文献

In geography, a conversation around suicide survivors and their suicidal journeys has yet to happen. The current prioritisation of suicide as end points marked on maps and patterns of death in space and regions has obscured the lived experience of adults who attempt suicide and do not die. In an effort to reduce this invisibility, evidence derived from in-depth interviews with adults (18 years and over reported as missing) who freely delivered narratives of their attempts is employed to understand the complex spatiality of suicide in retrospect. Situating suicide survivors as knowledgeable about their feelings, beliefs and experiences, the paper encounters testimonies of intended death via a focus on spatialised journeys: physical routes, pathways and places of attempted suicide. Discussing these particular journeys as socio-spatial process represents the potential for geographical scholars to rework geographies of dying and (attempted) death as an active practice. 相似文献

Recovered and amplified ancient DNA (aDNA), from a historically documented 19th century Upper Canadian pioneer cemetery produced genotypes that were used to infer a past societal kinship system. While the results from multiplex short tandem repeat (STR) amplifications showed an unreliable polymerase chain reaction (PCR) product, a single locus HUMTH01 analysis yielded reproducible data and an allelic frequency pattern not statistically different from modern populations. Mitochondrial (mt) DNA HVR II data showed that a combined cemetery database exhibited reduced haplotype diversity indicators, as well as clusters of probable maternally related burials. The chronological persistence and replacement of mtDNA clusters approximately every two generations suggests a patrilineal/patrilocal kinship structure from a virilocal burial program for the Harmony Road cemetery. Through the integration of the aDNA analysis with archaeological material culture, historic records, and other ethnohistoric sources of information, this conclusion is supported. In this study persisting patrilineally inherited surnames act as a surrogate for aDNA Y‐chromosome haplotype analysis. These results suggest that aDNA applications on aggregate skeletal collections where sparse, or no ethnological or historical documentation exists, may result in incorrect population history inferences if the presence of a kinship interment bias is not considered.

Optical Coherence Tomography (OCT) is a non-invasive subsurface 3D imaging technique based on the Michelson interferometer. The non-invasive nature of OCT and its speed of acquisition makes it possible to image large volumes of intact objects to yield a complete overview of the microstructure. The production methods for ancient Egyptian faience were first investigated using scanning electron microscopy (SEM) imaging of the microstructure in polished sections and microprobe analysis of the composition of the glass phases. These studies were based on original Egyptian faience objects and laboratory reproductions of faience beads made using three different production methods. The microstructure of the same laboratory samples and the Egyptian faience objects from the British Museum Research Laboratory Collection are re-examined using OCT. It is found that OCT virtual cross-section images can be used to group ancient faience objects into three categories on the basis of the morphology of the surface glaze layer and the glaze/core interaction layer. The OCT images correspond well with SEM images of polished sections of ancient faience objects and laboratory reproductions. The virtual cross-sections produced by OCT are somewhat limited by the penetration depth, which is affected by the high absorption coefficient of the material and, therefore, cannot always provide information on the presence or absence of interparticle glass that binds together the quartz particles in the core. Nevertheless, the top two layers are well imaged and since OCT images can be obtained rapidly and without the necessity of removing a sample, the method can be applied to a very much wider range of ancient faience objects than is possible by SEM examination of polished cross-sections. In summary, this paper examines to what extent OCT can assist the investigation of the production techniques of ancient Egyptian faience. 相似文献

THE EXCAVATION of Anglo-Saxon structures below the W. end of the 11th to 12th-century nave of the church of St Augustine's Abbey, Canterbury, occupied three seasons between and 1957. Further, small-scale, excavation took place subsequently on the site of the pre-Conquest church of Sts Peter and Paul to test particular points. The need for the excavations in 1955 arose unexpectedly out of routine consolidation of the upstanding remains (which are in the care of what is now the Department of the Environment), when there were discovered by chance the voussoirs of an arch a few inches below ground level in the ill-defined mass of masonry at the extreme SW. corner of the Norman church. 相似文献

This paper explores some of the consequences of using archival materials produced by an anthropologist's informants. What happens when a resident from a rural area of Cuba is hired to write about the “world”, a term used by Carl L. Withers, in which he, his relatives and his neighbours live? By reading letters and other papers sent during the late 1940s, and kept by Withers for more than thirty years, my hypothesis is that his informants took seriously their capacity to create something other than a simple “testimony”. Withers's principal informant, created himself, his neighbours, strange beings and the world in which they cohabited as a certain type of artefact, as “data”. 相似文献
