As part of an ongoing project at the World Heritage Site of Bukhara, we investigated the glue used in the construction of the Khoja Zaynuddin mosque. Analysis by a range of techniques confirmed that it consisted of a collagen‐based glue. However, the glue contained many non‐protein constituents. The presence of lipid material suggests that the glue was produced by a relatively unsophisticated process. More surprisingly, various marker compounds of urine were found. Study of the viscosity of a mixture of a modern collagen‐based glue and urea showed that the presence of urea at a concentration typical of human urine reduced the viscosity of the glue, thus improving its spreading characteristics and enabling its use at a lower temperature. Whilst the advantages of adding urea to glue were known to craftsmen in Europe and America in the 19th century, it would appear that the builders of Bukhara were aware of the technique, using less pure components, at a significantly earlier date.  相似文献

This paper discusses the problems with sampling materials and sampled contexts in the framework of radiocarbon dating of Mesolithic sites situated in generally dry, acid and bioturbated coversand deposits within north‐western Europe. The case studies presented all relate to the coversand regions of northern Belgium and the Netherlands, two areas for which very large sets of radiocarbon dates performed on different organic components are currently available. The study points out that charred hazelnut shells from surface hearths and charcoal from hearth pits guarantee the most secure dating results, while the dating of calcined bones and food crusts from Final Mesolithic pottery so far remains problematic.  相似文献

This paper presents a case study, based on the experiences of two senior Aboriginal traditional owners who were engaged in negotiations surrounding the establishment of a Regional Forest Agreement (RFA) in southeast Queensland. This case is notable as an illustration of the capacity of natural resource management planning, through negotiation within a formal process, to extinguish native title. Importantly, the personal experiences of two senior Aboriginal people provide an insight into a situation designed to enhance interactions between government and community, with the overt intention of improving natural resource management. However, the record of this personal experience indicates that the communication was less than satisfactory and that the outcomes, at least in terms of the experiences recorded here, of the individual senior Aboriginal community members, was less than satisfactory. We conclude that, despite best intentions, there is an important lack of provision for community influence or power, including any legal or administrative institutional framework. We also conclude that there are important institutional and social processes of engagement still to be developed, including ways of engaging the community more widely that has conventionally been the case.  相似文献

Explanatory pluralism has been defended by several philosophers of history and social science, recently, for example, by Tor Egil Førland in this journal. In this article, we provide a better argument for explanatory pluralism, based on the pragmatist idea of epistemic interests. Second, we show that there are three quite different senses in which one can be an explanatory pluralist: one can be a pluralist about questions, a pluralist about answers to questions, and a pluralist about both. We defend the last position. Finally, our third aim is to argue that pluralism should not be equated with “anything goes”: we will argue for non‐relativistic explanatory pluralism. This pluralism will be illustrated by examples from history and social science in which different forms of explanation (for example, structural, functional, and intentional explanations) are discussed, and the fruitfulness of our framework for understanding explanatory pluralism is shown.  相似文献

This article takes the Nietzschean dictum that history must “serve life” as a point of departure for an analysis of the American institution of Black History Month. Many continue to place great faith in the power of historical education to solve problems of race in America. Against this common‐sense view, this article argues that the excessive historicization of the problem of racism is at least as oppressive as forgetting. The black history propagated during this month has mostly been a celebration that it is history and thus a thing of the past. The article makes the claim that it is precisely a surfeit of black history that has encouraged the view that racism is vanishing in the river of time. The constant demand to view American racism through a historical frame has led to the perception that racism is a problem that must be historically transcended rather than solved. In other words, it is through the widespread dissemination of black history during Black History Month and elsewhere that the historical category of the post‐racial era has been constituted. The postracial era is not, as is so often claimed, a denial of historical context. On the contrary, it is an assertion that the horrors of racist discrimination were once real but are now over and done with.  相似文献

Frank Ankersmit is often perceived as a postmodern thinker, as a European Hayden White, or as an author whose work in political philosophy can safely be ignored by those interested only in his philosophy of history. Although none of these perceptions is entirely wrong, they are of little help in understanding the nature of Ankersmit's work and the sources on which it draws. Specifically, they do not elucidate the extent to which Ankersmit raises questions different from White's, finds himself inspired by continental European traditions, responds to specifically Dutch concerns, and is as active as a public intellectual as he has been prolific in philosophy of history. In order to propose a more comprehensive and balanced interpretation of Ankersmit's work, this article offers a contextual reading based largely on Dutch‐language sources, some of which are unknown even in the Netherlands. The thesis advanced is that Ankersmit draws consistently on nineteenth‐century German historicism as interpreted by Friedrich Meinecke and advocated by his Groningen teacher, Ernst Kossmann. Without forcing each and every element of Ankersmit's oeuvre into a historicist mold, the article demonstrates that some of its most salient aspects can profitably be read as attempts at translating and modifying historicist key notions into late twentieth‐century categories. Also, without creating a father myth of the sort that White helped create around his teacher William Bossenbrook, the article argues that Ankersmit at crucial moments in his intellectual trajectory draws on texts and authors central to Kossmann's research interests.  相似文献
