面向新世纪 ,史学家要以更为开放和健康的心态迎接史学面临的机遇和挑战。史学的繁荣与发展在某种意义上取决于它满足时代和社会发展的需求程度 ,史学要发展就必须“与时俱进”。中、外史学史都证明 ,史学的发展不是简单的史料积累 ,它首先需要的是史学家的观念更新和在此基础上的理论创新。近二十年来中国史学的发展历程也是不断改革开放和理论创新的过程。史学理论对史学研究的重要性已逐渐为国内史学工作者所认识 ,这使我们作为国内惟一的史学理论杂志的编辑深感责任的重大 ,我们只有认真地思考如何办好这份刊物 ,才不辜负新世纪史学工作者对我们的期望。为此 ,我们以“面向新世纪的中国史学理论研究”为题组织了这次笔谈。笔谈文章分两次刊出 ,希望引起史学界同仁对理论问题更多的关注和更深入的探讨  相似文献

In Homeric studies, the evidence of metrics has often been overlooked. The authors argue that the hexameter must be a recent development, closely bound up with the transition from an Aeolic to a Ionic phase in the development of the epic diction. The Ionic phase must have been very short, and the rise of the Iliad is probably also to be situated at the very moment of change in meter and dialect.  相似文献

In this work we present data obtained from experiments with wild brown bears from the Cantabrian Mountains in northern Spain. Our results show that wild brown bears do not take carcasses to their dens, but can displace them by tens of meters before eating them, and the remains can become dispersed some meters around the place where the carcass is consumed. The long bones of large-sized carcasses show no fractures, but they do show tooth marks (scores, pitting, punctures and furrowing) especially on the cancellous bone of the epiphyses. Ribs and vertebrae show fractures and furrowing. The innominate also shows furrowing on cancellous bone of the ilium and ischium. The results of this study are in agreement with previous work and also shed some light on the behavior of this carnivore in the wild. The data gathered are of great importance when interpreting paleontological and archaeological sites where the bear is a likely taphonomic agent.  相似文献

Although landscape research has not been set apart formally as a distinctive branch of geography in the West, the methods used in certain research programs in the United States and in Australia come close to the integrated areal approach to the study of the physical environment characteristic of Soviet landscape science. In the United States, landscape-like methods are used by the Soil Survey staff of the Department of Agriculture in its soil surveys of counties. In Australia, the landscape approach is used by the Division of Land Research of the Commonwealth Scientific and Industrial Research Organization in its reports on Australia's land systems.  相似文献

Roman millstones of assumed Eifel origin were produced and exported in huge quantities to many parts of Roman Europe and can be used as tracers for trade patterns in Roman times. This study presents for the first time a raw-material centred geochemical definition of the 13 well-known Roman basaltic lava quarries in the Quaternary East and West Eifel volcanic fields. The aim is to find a way to characterize the individual exploitation sites precisely by means of their geochemical composition and to recommend a standard procedure for further millstone provenance analysis. Based on major and trace element composition analyses by XRF, a differentiation of each quarry is achieved by using a combination of geochemical discrimination and cluster and discriminant analysis. Therefore, for provenance analysis of a unknown millstone sample the following procedure is recommended: (1) geochemical discrimination to check if it actually belongs to the volcanic Eifel quarries; (2) cluster analysis to check to which quarry or cluster of quarries the millstone can be affiliated; and (3) discriminant analysis to assign the sample to its quarry of origin with a certain confidence.  相似文献

The first case of synesthesia was reported in 1812 ( Jewanski, Day, & Ward, 2009 ). However, it took almost seven decades before the idea of synesthesia entered the mainstream of science and, subsequently, art. There are no known new cases described between 1812 and 1848, but in the following three decades there are at least 11 reported cases of synesthesia and many reviews of these cases. This comes at an important period in the history of the neurosciences, and for sensory physiology in particular. However, the literature that describes synesthesia during this period is largely unknown to contemporary researchers and historians. The aim of this review is to discuss the reports of synesthesia during this period, providing translations of some key passages, and to place these reports within the contextual framework of nineteenth-century neuroscience.  相似文献

Three rock samples and associated underlying surface (floor) soils of geoarchaeological significance from Greece, Sweden and a modern surface stone-sample from a Danish site were investigated using OSL dating. Thin slice, sub-samples, from drilled core surfaces were prepared. A single-aliquot regenerative-dose (SAR) protocol was used on whole rock slices to estimate the laboratory equivalent dose. Laboratory tests showed that the SAR protocol successfully corrected for sensitivity changes and that a known laboratory dose could be measured accurately.  相似文献

This article suggests that President Obama's consistent references to the extremist Sunni group as ‘ISIL’ (Islamic State of Iraq and the Levant) is not a trivial matter of nomenclature. Instead, the Obama administration's deliberate usage of the ISIL acronym (as opposed to other commonly‐used terms such as ‘Islamic State of Iraq and Syria’ or ‘ISIS’, ‘Islamic State’, ‘IS’, ‘so‐called Islamic State’ and ‘Daesh’) frames the public perception of the threat to avoid engagement with the requirements of strategy and operations. Both the labelling and the approach could be defended as a response to the unique challenge of a transnational group claiming religious and political legitimacy. However, we suggest that the labelling is an evasion of the necessary response, reflecting instead a lack of coherence in strategy and operations—in particular after the Islamic State's lightning offensive in Iraq and expansion in Syria in mid‐2014. This tension between rhetoric, strategy and operations means that ‘ISIL’ does not provide a stable depiction of the Islamic State. While it may draw upon the post‐9/11 depiction of ‘terrorism’, the tag leads to dissonance between official and media representations. The administration's depiction of a considered approach leading to victory has been undermined by the abstraction of ‘ISIL’, which in turn produced strategic ambiguity about the prospect of any political, economic or military challenge to the Islamic State.  相似文献
