In this study we applied a multidisciplinary approach, coupling geophysical and geochemical measurements, to unveil the provenance of 170 obsidian flakes, collected on the volcanic island of Ustica (Sicily). On this island there are some prehistoric settlements dated from the Neolithic to the Middle Bronze Age. Despite not having geological outcrops of obsidian rocks, the countryside of Ustica is rich in fragments of this volcanic glass, imported from other source areas. The study of obsidian findings was carried out first through visual observations and density measurements. At least two different obsidian families have been distinguished, probably imported from Lipari and Pantelleria islands. Analysing the magnetic properties of the samples, these two main sources were confirmed, but the possibility of other provenances was inferred. Finally, we characterized the geochemical signature of the Ustica obsidians by performing microchemical analyses through electron microprobe (EMPA) and laser ablation (LA–ICP–MS). The results were compared with literature data, confirming the presence of the Lipari and Pantelleria sources (Sicily) and indicating for the first time in this part of Italy a third provenance from Palmarola island (Latium). Our results shed new light on the commercial exchanges in the peri‐Tyrrhenian area during the prehistoric age.  相似文献

Archaeomagnetic dating based on the full geomagnetic field vector was carried out on a limekiln excavated at Pinilla del Valle archaeological site (Madrid, Spain). The limekiln tradition in this area is largely documented by historical sources for recent centuries but the date of the studied kiln's last use was unknown. The combination of mean archaeomagnetic directional and absolute archaeointensity results shows that the kiln was last used between ad 1296 and 1413, in good agreement with two independent radiocarbon dates. This study provides the first archaeomagnetic evidence that the local limekiln tradition dates back to at least late medieval times. Furthermore, the inclusion of these data in the Iberian secular variation curve and geomagnetic field models will help to improve the archaeomagnetic dating technique.  相似文献

Accurate interpretation of the cause and timing of bone breakage is essential for understanding the archaeological record. However, many variables potentially influencing break morphology have yet to be systematically explored. Focusing primarily on hammerstone breakage, we introduce new analytical methods for comparing fracture angles using the absolute values of the angle from 90°. We systematically control for intrinsic variables such as taxon, skeletal element, limb portion and skeletal age. We also compare experimental assemblages of femora broken by hammerstone and spotted hyena (Crocuta crocuta). We show that fracture angles are influenced by breakage plane, skeletal element and limb portion. While the latter two have been suggested before, this is the first time the differences have been quantified. We suggest that researchers stratify their assemblages by these variables if they are using fracture angles in analyses. At the assemblage level, hyenas created more oblique fracture angles on oblique breaks than did hammerstones.  相似文献

ABSTRACT

Since the early modern era, following the abolishment of the imperial civil service exam and the rise of modern schools, the subject of history was included in education at all levels, from primary to tertiary. However, in comparison with traditional society, the degree of attention devoted to historical knowledge has in fact declined rather than improved. In the 1920s, many contemporaries vocally criticized and pondered the low level of historical knowledge among primary and secondary school students, and occasionally voiced dissatisfaction with history education at the university level as well. Critics primarily focused their discussions on the insufficient attention for history classes, imperfect standards formulated for history classes, poor history teaching materials, and lack of qualified, specialized teachers, forming a universal consensus among contemporaries on the failure of history education. However, the widespread opprobrium attached to history education was closely tied to two facts: first, the historians of early modern China had as yet failed to compile a general history of China acceptable to the majority, greatly disappointing many educators; second, historical resources failed to exercise the mobilizing effect on early modern Chinese society that contemporaries had hoped for, and history thus often became the scapegoat paying the price for practical setbacks and failures in the political arena.  相似文献

Contemporary theorists of international relations and historians of empire have found utility in the spatial theory of “Grossraum,” or “great space,” that Carl Schmitt developed in the 1930s and 40s. This article asks whether Schmitt's concept of Grossraum can be fully disentangled from its German history—from the Nazi pursuit of Lebensraum in which it eventually culminated, but with which it is not identical either. I argue that Schmitt's Grossraum theory is neither merely a symptomatic reflection of the Third Reich's objectives, nor a free‐floating theory with strong potential for critiquing imperialism, but is best approached as an important moment in the transatlantic conversation among empires that unfolded between 1890 and 1945 about the sources, methods, and prerogatives of global power. It compares Schmitt with other figures in German geopolitics such as Friedrich Ratzel and Karl Haushofer in order to establish a genealogy of the distinction between land and sea powers, arguing that Schmitt's writings on Grossraum modernize and transmit to the twentieth century the most influential theories of political geography and geopolitics developed in the Atlantic world between 1890 and 1930.  相似文献

The Aboriginal people of the Upper Finke River in central Australia have followed a literacy tradition for over 130 years. When the first Lutheran missionaries arrived, they immediately started to study the local Arandic language and were teaching reading and writing by 1879. Despite this long exposure to literacy and the Lutheran influence on it, the issue of the right orthography for this Arandic language variety is emotionally charged and politically very contested. In this post‐colonial context, orthography has become a sociocultural and symbolic, rather than a phonemic, matter.  相似文献

Isaac Newton, like many of his contemporaries, appears to have distinguished between the practice of divinity, founded on divine revelation, and philosophical considerations of God derived from the study of nature. This article evaluates these distinct modes of divine discourse through a close reading of the chymical content of Newton’s optical writings and his correspondence with Thomas Burnet regarding Genesis. Newton’s chymical exploration of divine activity in the natural world in Query 31 to the Opticks (1704) seems independent from Scripture in its physico-theological demonstration of God from natural phenomena and its divine metaphysical reliance on a priori concepts of God to establish principles of nature. Nonetheless, the sensorium analogy by which he explored divine agency in nature drew directly from the biblical doctrine of the imago Dei. Moreover, Newton used his chymical understanding of nature to access the natural-philosophical realities behind the accommodated words of the Mosaic creation account.  相似文献

ABSTRACT

This paper traces the engagement of Graham Greene's novel A Burnt-Out Case with traditional discourses of leprosy (the biblical ‘leper’ as a sinner, missionary care, tropical medicine, Albert Schweitzer's hospital in Lambaréné, germ theory), and shows how it suggests an ethics of care which highlights the psychosocial aspects of disease and healing. The paper argues that the reception of the novel opened a discursive space for the re-negotiation of images of leprosy after empire, making visible the structures and agents of global public health communication and their diverging conceptions of explanatory authority, scientific accuracy and the relation of science and literature. The article incorporates archival sources from press reviews to draft versions of the novel and the author's correspondence with prominent leprosy experts. It draws on media and science communication studies, disability studies and on contributions to the sociology of knowledge by Ludwik Fleck, Thomas Kuhn and Bruno Latour.  相似文献

In 2014, the Vienna Convention on Diplomatic Relations celebrated its fiftieth anniversary since its coming into force in 1964. Setting out the privileges and immunities accorded to diplomats and diplomatic missions, the negotiations of this convention were part of the United Nations' plan to strengthen the international rule of law. This article analyses the role of Britain, one of the major actors in the negotiation process. It explores how Britain's negotiation position was shaped by diplomatic realities of the 1950s, and the strategies used to ensure Britain's interests being reflected in the final convention. The focus will be on the overall political pressure that underlined Britain's negotiation position, in order to reveal the general UK position on the codification of diplomatic privileges and immunities. Despite the remarkably friendly atmosphere at the 1961 Vienna conference, Britain could not press through all its amendments which, through the concluding legislation process, protracted Britain's ratification process. The article shows while London was supporting the codification of international law, codification by convention was not its ultimate choice. Therefore, the subsequent legislation process was marked by an inter-departmental dispute between the Foreign Office and Treasury, inter alia, on the exemption of Scotch whisky from excise duties.  相似文献

This article explores the nature of security training chiefly associated with MI5. It shows that, akin to the security training implemented throughout the colonies, policy-makers in London hoped to strengthen Middle Eastern security services via British training, which would safeguard British interests in the region. This article argues that an unintended consequence was that strengthening Middle Eastern security services became part of the problem rather than the solution. The policy served mainly to bolster increasingly unpopular, authoritarian regimes against a rising tide of anti-British sentiment. Thus, British foreign, more specifically anti-Communist, policy in the Middle East was short-sighted and a failure.  相似文献
