The small mineral-binding bone protein, osteocalcin, has been applied in a number of studies on ancient bone due to predictions of its long-term stability. However, the intact protein has not been shown to survive in ancient bone devoid of DNA, which is a much more phylogenetically informative biomolecule. In this investigation, the survival of osteocalcin is directly compared to the amplification of mtDNA in a set of 34 archaeological samples from four sites throughout Europe. We also present unpublished osteocalcin sequences of seven mammalian species in addition to the 19 published sequences to highlight phylogenetic limitations of this protein. The results indicate that the intact osteocalcin molecule survives less in archaeological samples than mtDNA and is more subject to the temperature of the archaeological site. Amino acid analyses show the persistence of the dominant protein collagen in samples that failed both osteocalcin and mtDNA analyses. The implications these findings present for biomolecular species identification in archaeological and palaeontological material are that, although proteins do survive beyond ancient DNA, osteocalcin does not appear to be the most ideal target.  相似文献

The centenary of the Easter Rising in 2016 and the 150th anniversary of James Connolly’s birth in 2018 afford an ideal opportunity to reappraise this unique figure. Rightly renowned for his polemical journalism and political theory, Connolly is less celebrated for his creative writing. His 1916 play, Under Which Flag?, long considered lost, resurfaced fifty years ago without causing significant ripples in Irish literary circles, but interest in Connolly’s role in the struggle for Irish independence continues to grow, and critics are becoming increasingly aware of the fusion of feminist and socialist thought that shaped his particular anti-imperialist agenda. In this context his creative writing takes on new significance. A second lost play of Connolly’s, The Agitator’s Wife, has never been found, but its discovery would surely deepen our understanding of this gifted radical thinker. In this essay we suggest that an anonymous short story bearing that very title, published in a short-lived Christian socialist journal of the 1890s, may be a crucial missing piece in solving the puzzle of Connolly’s forgotten drama.  相似文献

The 11,000-year old lake edge archaeological site of Star Carr in the Vale of Pickering of North Yorkshire is one of the most famous Mesolithic sites in Europe, and one of the earliest, dated to the period of climatic warming that immediately followed the final termination of the last ice age. One of the main reasons for this international importance is the richness of its organic artefacts, faunal assemblage and environmental data. However, recent investigations have demonstrated that these organic remains have severely deteriorated over the last 60 years due to the decay and acidification of the surrounding peat. This paper presents research into the effects on the bone (histological analysis using light and polarising microscopy, and Transmission Electron Microscopy, bulk collagen analysis, and amino acid analysis), antler (visual and metrical analysis, loss on ignition and Scanning Electron Microscopy) and wood (visual analysis, decay assessment tests and Scanning Electron Microscopy).  相似文献

In March 2011, a conference was held at the University of Aberdeen, Scotland, focusing on the possibilities and potentials of combining quantitative spatial studies with more human-centred and theoretically explicit approaches to past landscapes. This short introduction outlines the main themes and goals of the conference and the resultant papers, published here as a special issue.  相似文献

This article explores a protracted dispute in the exchequer of receipt that initiated lasting procedural reform. The argument revolved around contested narratives of exchequer history which had direct implications for officers’ fees, rights and status. The ferocity of the dispute has rendered it one of the most-studied episodes in exchequer history, yet historians have largely focused on procedural reform and dismissed the ardour of the protagonists. This article recontextualises the dispute within its political and physical context in the Palace of Westminster to argue that the feud was not merely personal but political. By drawing together officers’ personal papers with exchequer records and architectural records of the palace, this article demonstrates the agency of individuals in influencing institutional reform. The protagonists operated within webs of overlapping loyalties between crown, institution and patrons which reflects the place of the Receipt in central government. Consideration of the warring officers in this context reveals that the outcome of the dispute was not in spite of their passions, but a product of them.  相似文献
