In the context of the present study, we have conducted chemical and lead isotope analyses on twelve ancient glass samples unearthed from Chu tombs in Changde City, Hunan Province. The results of the chemical analysis of these samples show that all samples are PbO–BaO–SiO2 glasses, thus indicating that they are all traditional ancient Chinese glasses. The chemical results also suggest that all Bi wares may either share a common source or were produced according to similar recipes. In turn, the eye beads are different from the Bi wares for their distinct chemical composition. The chemical results indicate that silica, lead-bearing material, barium-bearing material, and sodium/lime-bearing material are the main independent components of the raw materials employed in the production of these glass wares. 相似文献
Excavation of the Micoquian site Inden-Altdorf (Weisweiler-124) near the former German capital Bonn in western Germany has revealed the first valid open-site habitation features with hut-like structures and associated hearths for the Middle Palaeolithic in Central Europe. It has been dated to the Eemian interglacial (OIS 5e), a warm interglacial between 128 and 115 ka BP. Various wear traces and especially organic residues have been detected on a large number of stone tools using microscopic use-wear analysis of lithics recovered from the site. A multi-level analysis developed through an experimental framework and archaeological study using optical light microscopes, scanning electron microscopes and energy-dispersive X-ray microprobes identified the adhering residues as birch pitch. Birch pitch is the oldest synthetically produced material and was used as an adhesive to attach lithic implements to wooden shafts. While such hafting technology is commonly associated with modern humans in the Upper Palaeolithic, the birch pitch residues found on the Micoquian tools of Inden-Altdorf suggest that hafting technologies and the frequent use of multi-component tools already existed in the Middle Palaeolithic, c. 120 ka BP in central Europe. 相似文献
Abstract: In contrast to assertions that the capitalist state is either losing control or that it has returned, this article argues that during the last two decades the state itself has been reshaped. To understand the processes that the capitalist state is exposed to it is necessary to conceive of it as a series of form‐specific practices. Which practices form “the state” is not a result of pre‐given institutions but of conflicts and struggles. The capitalist state, separated as it is from the relations of production, must not be made synonymous with the national state. Only as a result of certain relations of force does bourgeois rule acquire the form of the national state. These relations between classes are currently being dissolved by the ruling classes. The capitalist state is being reorganized and is constructing new elements of a transnational network state, whilst the state itself is governed through new techniques—that is, those of governance. 相似文献
AbstractThis paper presents the results of research carried out for more than a decade at Vuelta de Obligado, San Pedro, north-east of Buenos Aires province. The objectives were to understand the dynamics of the strategy followed on the 1845 battlefield by the two groups who fought (Anglo-French and Argentine), and to assess the impact of formation processes on the results produced. This has been achieved through the use of several sources of information: the archaeological record, written documents, Argentine and European plans and sketches, as well as data provided by the current population. 相似文献
During the Cold War, a number of societies established stable democracies despite having low levels of modernisation and relatively few democratic neighbours. Threshold levels of modernisation and neighbouring democratic societies are consistently related to the endurance of democracy. Meanwhile, the Cold War superpowers often supported autocracies, making it even more difficult to maintain democracy. Analysing these stable but ‘deviant’ democracies provides an opportunity to examine how domestic factors influence regime stability. In particular, such historical cases advance understanding of contemporary patterns of democratic stability. Previous research has not systematically identified deviant democracies before 1989. This research note does so using a large-N analysis of 125 societies during the first phase of the third wave of democratisation, from 1975 to 1988. It identifies 11 deviant democracies, including Bolivia, Botswana, Colombia, Costa Rica, the Dominican Republic, Honduras, India, Jamaica, Mauritius, Trinidad and Tobago, and Turkey.
Given their precarious position within larger states, national minorities cannot rely on federal governments to affirm their nationhood. Moreover, insofar as nationhood is predicated on a shared history, language and culture, immigrants place additional strains on the maintenance of national distinctiveness and the political claims that derive from it. In 2006–2007, following a series of confrontations over religious practices in the public sphere, Québec's provincial government appointed the Bouchard–Taylor Commission to investigate avenues for the accommodation of immigrant‐related cultural and religious differences. While it failed to generate policy, the commission did provide a discursive space for the (re)assertion of Québécois nationhood. Analysing the production of national identity in newspaper debates of the Bouchard–Taylor report, we offer an alternative to the ethnic–civic paradigm in nationalism theory. Rather than treat ethnic and civic as two separate ends of a single continuum, we conceptualise a relationship between two dimensions: one of culture and one of politics. We show that in contemporary articulations of Québec national identity, the prerequisites of political membership derive their meaning from a productive tension between blood‐based and adoptive conceptions of national culture. 相似文献
Researchers are increasingly aware that nonlinear perspectives of the transition into adulthood and non-economic motives, such as family and friends, may help to improve our understanding of young adults' migration decisions. This paper combines these new insights with the traditional economic success–failure arguments in order to explain young adults' return migration to their rural home region. We present four orientations in return motives: the social, family, functional and partner orientation. They consist of different combinations of the stereotypical success–failure arguments with non-serial transitional stages, and with different attachments to the home region. They also show that in some cases, return migration should actually be interpreted as staying in the home region, because the young adult returnees had not mentally left the region. We therefore state that our results provide a solid argument for reinterpreting the out-migration of young people from rural areas. 相似文献
This paper is a preliminary overview of the main characteristics of the archaeological resource of Oman from a management perspective. It looks at the resource in terms of form, space and time. It covers a pilot statistical analysis of the archaeological data so far input into the proposed National Archaeological Database of Oman (NADO). The main findings of this analysis show that the management of Omani archaeological resource lacks a well‐defined strategic research plan, and that there are large research gaps in many geographical and chronological areas. It also shows that the governmental organisations responsible for the management of the country's archaeological resource are not taking into consideration the potential benefits of archaeological records in their management practices. 相似文献
The emergence of neurology as a separate specialty from internal medicine and psychiatry took several decades, starting at the end of the nineteenth century. This can be adequately reconstructed by focusing on the establishment of specialized journals, societies, university chairs, the invention and application of specific instruments, medical practices, and certainly also the publication of pivotal textbooks in the field. Particularly around 1900, the German-speaking countries played an integral role in this process. In this article, one aspect is extensively explored, notably the publication (in the twentieth century) of three comprehensive and influential multivolume and multiauthor handbooks entirely devoted to neurology. All available volumes of Max Lewandowsky's Handbuch der Neurologie (1910–1914) and the Handbuch der Neurologie (1935–1937) of Oswald Bumke and Otfrid Foerster were analyzed. The handbooks were then compared with Pierre Vinken's and George Bruyn's Handbook of Clinical Neurology (1968–2002).
Over the span of nearly a century these publications became ever more comprehensive and developed into a global, encompassing project as is reflected in the increasing number of foreign authors. Whereas the first two handbooks were published mainly in German, “Vinken & Bruyn” was eventually published entirely in English, indicating the general changes in the scientific language of neurology after World War II. Distinctions include the uniformity of the series, manner of editorial involvement, thematic comprehensiveness, inclusion of volume editors in “Vinken & Bruyn,” and the provision of index volumes. The increasing use of authorities in various neurological subspecialties is an important factor by which these handbooks contrast with many compact neurological textbooks that were available at the time.
For historiographical purposes, the three neurological handbooks considered here were important sources for the general study of the history of medicine and science and the history of neurology in particular. Moreover, they served as important catalyzers of the emergence of neurology as a new clinical specialty during the first decades of the twentieth century. 相似文献
