Archaeologists' reconstructions of paths to complexity have all too often excluded complex hunter-gatherers. However, recent theoretical contributions and long-term field research programs in several regions of the world have now significantly advanced our understanding of complex hunter-gatherers. A discussion of definitions of complexity and a review of current models of the emergence of complexity provide a framework for analyses of complex hunter-gatherers and important cultural phenomena such as sedentism, political integration, prestige economies, feasting, and ideology. 相似文献

The Revolution of 1959 brought forth changes in the mission, theoretical orientation, and organization of archaeology in Cuba and created a role for, and constraints on, the profession that are unique in the Western Hemisphere. This paper draws upon examples from substantive field and laboratory research to examine the methods and theoretical perspectives of Cuban archaeology since the Revolution, focusing on the period from 1962 until the collapse of the Soviet Union. Archaeological practice during the Revolutionary period in Cuba has reflected the aims of the Revolutionary government, the influence of Soviet archaeology, the legacy of pre-Revolutionary approaches in North American archaeology, and the Cuban sense ofpatria. 相似文献

Determination of the Fineness of Medieval Coins—Evaluation of Methods in a Case Study of a Medieval Pfennig

The original fineness of coins is very important information that can help us to understand the commercial situation in a wide historical context. This paper deals with a comparison of analytical methods suitable for the evaluation of the actual and original fineness of coins based on a detailed case study of a medieval coin sample. Both non‐destructive (i.e., scanning electron microscopy/energy‐dispersive X‐ray spectroscopy, X‐ray fluorescence, atomic force microscopy and hydrostatic weighing) and destructive (i.e., inductively coupled plasma – mass spectrometry and the Volhard titration method) techniques were used. The original fineness can be also deduced from knowledge of the internal structure of the coin (limited miscibility of copper and silver). A new analytical method based on a combination of a micrograph of the metallographic cross‐section with consequent image analysis was developed for determination of the original fineness. The proposed approach is relatively simple and provides reliable values. Sample heterogeneity and its impact on the determination of fineness are also discussed. 相似文献

We present a new curve of the directional secular variation of the geomagnetic field in Western Europe between 1500 bce and 200 ce . Its computation relies on a Bayesian framework. The fast secular variation during the Late Bronze and Early Iron Ages makes archaeomagnetic dating efficient with a respective precision of 150–200 and 60–100 years during these periods. The Bayesian method also provides posterior date distributions that refine the dating of reference data, especially during the period of the Hallstattian radiocarbon plateau. Archaeomagnetism becomes a valuable alternative to radiocarbon and will help to improve the archaeological chronologies. 相似文献

New technologies enable high‐resolution monitoring techniques and the generation of big data and have been heralded as increasing the depth of our understanding of geomorphic phenomena. These technologies, however, also provide us with a convenient entry point into the increasingly constraining political economy of geomorphology. Building on the work of Stuart Lane and of critical physical geographers, this paper traces and examines the multiple roles that new technologies have played in constraining research questions and directing resources. Using the activity sphere framework outlined by David Harvey, the influence of new technologies can be traced around the spheres and their constraining of existing relations within academia and explanation identified. 相似文献

British idealism has led an ambiguous existence in any overview of British historical and political thought in the twentieth century. Seen partly as an alien Continental intrusion into presumably typical British priorities of empiricism, positivism, and utilitarianism, it was badly damaged by its putative associations with the military enemy of two world wars. Admir Skodo's meticulous study of British “idealist revisionists” during the postwar period 1945–1980 repairs this damage by showing the extended influence of that idealism as funneled through the “new idealism” of the interwar period represented mainly by the philosophers R. G. Collingwood and Michael Oakeshott. Skodo demonstrates how these idealist revisionists deeply influenced postwar British historiography by underscoring qualities of humanism, pluralism, and variety not characteristically associated with idealism, reinterpreted a range of important topics in British history from the Tudors through the English civil wars to the Victorian period, and came up with political theorizing that celebrated the postwar welfare state while indicating its vulnerabilities to an increasingly technologized society. Just as Skodo's protagonists negotiated the 1970s transition in Britain's turn to Europe, so his account proves stimulating for contemporary concerns regarding a post‐Brexit Britain. The final part of the essay therefore looks at some suggested models, such as the “Anglosphere” or a “Singapore in the Atlantic” for Britain, before concluding with reflections on the importance according to a Hegelian reading of the modern “rational state” of the continued influence of Oxbridge intellectuals on the evolution of British directions and goals since the Victorian age. 相似文献

This article offers a re-contextualization of the Positivism Dispute between the Frankfurt School and advocates of empirical sociology in the German sociological profession between 1954 and 1970. Investigating the reasons why the German Sociological Association convened in Tübingen in October 1961, it assigns a more peripheral role to Karl Popper and this now famous seminar. Focusing instead on the debate among German sociologists from the mid-1950s which prompted the convention of the seminar and the invitation for Popper to speak, the article maintains that philosophy of history was the central concern of the Positivism Dispute. In this debate, members of the Frankfurt School emphasized contingency in history and society, while sociologists such as René König, Helmut Schelsky, Ralf Dahrendorf, and Arnold Gehlen advocated sociology as the empirical study of ‘given’ social facts. By doing so the article questions the narrative of the Positivism Dispute advanced by Karl Popper and some of his followers, as well as interpretations which have focused on debates during the aftermath of the Tübingen seminar in the 1960s. 相似文献
