Models of traditional boats stitched together with thread or cane from different parts of the world are commonly found in museum collections. They are often highly detailed and assembled in a way that is characteristic of a particular region. Through the presentation of a range of sewn‐boat models, particularly focusing on those from Sri Lanka, this paper considers how representative models are of full‐size boats, and if they can tell us about boat types and construction techniques. It provides guidance on using and interpreting models and aims to promote the use of these objects to further understand sewn boats. 相似文献

Flodoard of Rheims is one of the most important authors of tenth‐century Europe, and the only contemporary historian to document the momentous struggles between kings and nobles in Francia in the wake of the demise of the Carolingian Empire. Flodoard's era stands at the center of major historiographical debates concerning the nature of political and social change and the origins of European institutions. Yet, despite his singularity, his substantial histories have received little attention from scholars examining the profound transformations of the period. Exploring this discrepancy, this article offers an overview of Flodoard's career and reviews how his histories have been invoked in some of the great scholarly debates about tenth‐century Europe. It further proposes to recontextualize Flodoard and to reread his histories from the bottom up in order to gain a subtler understanding of how one contemporary perceived and represented the dramatic events and changes taking place around him. 相似文献

In 2010–11 a pedestrian survey of the western end of Wadi al‐Hijr in northern Oman identified 1507 archaeological features in a 124 km2 area. Data were collected on each feature's architectural characteristics, associated artefact assemblages, topographic and environmental locations, condition of remains, and relations to other archaeological features. The majority of datable features belong to the third millennium BC and divide unequally between the Hafit and Umm an‐Nar periods. While the majority of these third‐millennium BC features were tombs, other feature types were identified, including towers, settlements, quarries, dams, enclosures, and possible platforms. Third‐millennium BC features were organised into clusters and ranged considerably in size, from a few features to several hundred. All of the clusters established during the Hafit period were maintained in the Umm an‐Nar period, suggesting a continuity throughout the third millennium. Some preliminary hypotheses regarding settlement patterns are suggested. 相似文献

Marine resources were an integral and consistent component of subsistence strategies employed in south‐eastern Arabia throughout late prehistory. Of particular interest is the movement of these resources from the coast to interior sites and the implications of this movement for transhumance and trade in the region during this period. Marine species were frequently identified in the faunal assemblage from the inland site of Saruq al‐Hadid, dating from the Bronze Age to Early Iron Age (c.2000–c.800 BCE). This included marine fish species, along with two cormorant species (Phalacrocorax sp.) and several fragments of dugong (Dugong dugon). Twenty‐seven families of marine shell were also identified in the remains recovered from the site. The presence of these remains at this inland site demonstrates that resources were frequently moved from the coast to the interior throughout Saruq al‐Hadid’s occupation, indicative of their enduring significance in subsistence strategies employed at the site. This paper presents the results of zooarchaeological analysis of these remains and discusses the significance of their presence at Saruq al‐Hadid, with reference to subsistence, craft production and intra‐regional exchange during the Bronze and Iron Ages. 相似文献

This article is an exploration of concept of monks as “soldiers of Christ” in Byzantine Anatolia during the late sixth and early seventh centuries CE. Through a case study of Theodore of Sykeon, this article will explore monks as agents of continuity in the Byzantine Anatolia of the late sixth and early seventh centuries through Theodore's conflicts with the emperors, imperial authorities, and the regional episcopal hierarchy. The conflicts Theodore had with various authority figures of his time were about helping them see the right path of supporting Catholic orthodoxy as the normative belief system of Byzantine society and integrating his rural community of Sykeon into the wider web of imperial and episcopal urban patronage. Thus, conflict in this context was a catalyst for social order and stability rather than a symptom of social collapse. This article also fits into the historiography of the holy man as local patron in Late Antiquity, suggesting an alternate interpretation of this phenomenon as first put forward in Peter Brown's seminal works on this subject. 相似文献

Understanding cooperation among authoritarian regimes remains a puzzle for researchers; in particular, those working in post-Soviet Eurasia. Research suggests that autocrats are becoming increasingly coordinated in their efforts to thwart democracy, with authoritarian-led regional organizations offering an effective vehicle to extend autocrat time horizons. In contrast, older studies, including insights from failed regional integration among former Soviet states, suggest that the absence of democracy limits cooperation, although in both cases there is a lack of detail on the mechanisms enabling or constraining relations between autocrats. This article addresses this shortcoming by developing a theoretical framework based around autocrat survivability or “regime security” and applying it to the important case of the newly formed Eurasian Economic Union (EAEU), drawing on original interview data with experts and stake-holders in Belarus, Kazakhstan, and Russia. The argument forwarded in this article is that concerns over regime security create antagonistic cooperation drivers. In the case of the EAEU, regime security provides a strong explanation for the inability of member states to coordinate policy. The implication is that future studies should pay close attention to the way the material and ideational aspects of authoritarian rule combine to drive, but also limit relations between autocrats. 相似文献

This paper presents the findings arising from neutron activation analysis (NAA) of northern Chilean domestic ceramic samples from Caleta Vitor (n = 38) and clay samples (n = 15) from nearby valley, coast and highland contexts. This study presents the first NAA data set of ceramics spanning a temporal period of 1500 years (c.2000 to c.476 bp ) from the Vitor Valley as well as the first attempt to use NAA to characterize potential clay sources in the region. On the basis of this study, we argue that the majority of domestic ceramics from Caleta Vitor share compositional similarities with clay samples collected from nearby valleys, allowing us to infer that the Caleta Vitor populations primarily procured their clay for domestic ceramics from local sources throughout a 1500‐year period. Thus, despite the fact that there were inter‐regional interactions during this period that included the influence of powerful Andean polities, it would appear that domestic ceramics continued to be produced locally, and by implication it can be argued that such interactions did not substantially affect this sphere of material culture production. Further, the apparent continuities in domestic ceramic production allow us to reflect on local decision‐making processes throughout the cultural phases considered in this research. 相似文献

As the sobriquet «Zweistein» suggests, within the theoretical physics community Wolfgang Pauli came to be regarded as second in eminence only to Albert Einstein. Over a period of thirty-five years, they interacted both intellectually and personally. This paper focuses on four interrelated topics of their discussions. 1) The theory of relativity: at the age of twenty, Pauli prepared the definitive survey of relativity, a survey which he revised near the end of his life and which remains invaluable to physicists and historians of physics. 2) Unified field theories: although initially sympathetic to Einstein's search for a unified theory of electromagnetism and gravitation, and having made important contributions to the subject, Pauli came to regard such efforts as fruitless. 3) Foundations of quantum mechanics: Pauli's negative evaluation of Einstein's program grew out of their sharply differing evaluations of the role that quantum mechanics would play in the future, development of theoretical physics. 4) Quantum gravity: Pauli recognized that, until the achievement of a successful reconciliation of quantum mechanics and general relativity — an achievement that still eludes us — Einstein's challenge to quantum mechanics could not be laid to rest. 相似文献
