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

The chronology of the period is briefly considered in the light of the dendrochronological results which have appeared in recent years. Patterns of settlement history in different parts of the area are then examined, and it is suggested that in some of them the late fourth millennium was a period of population decline which was not reversed until the Early Bronze Age, 1000 years later. Detailed information about specific local occupation patterns is provided by recent work on the circum-Alpine lake villages. Changes in cultural patterns during the period, especially the appearance of the Corded Ware, are discussed and explanations of them reviewed. It is argued that changing patterns of gender relations were a major feature of the period, linked to processes which eventually led to the development of small-scale chiefdoms. The development of copper and bronze metallurgy and its connection to these processes are discussed.  相似文献

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

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

This paper examines the diversity of uses of Adam Smith’s ideas in nineteenth-century American debates about the tariff. Legislative debates about American trade policy ran almost uninterrupted from the 1820s to the end of the century; as a result, they provide an abundance of examples of the ways in which legislators marshaled economic ideas to shape political discourse and influence policy. Smith’s causal ideas about free trade and its effects were referenced in policymaking, and Smith’s intellectual authority was often invoked as a legitimating device for partisan ideology. These uses, I argue, contributed to the sloganizing of Smith as the ‘apostle of free trade’ and his enduring popularity as a political icon in American politics.  相似文献

A millennium ago in Northern Song (960–1127) China, Emperor Huizong initiated the “Eight Virtues of Conduct” in order to recruit morally upright officials. In place of the candidates’ skills in literary composition and understanding of the Confucian classics, this scheme adopted candidates’ moral virtues as their major criterion of selection. This paper analyzes how this scheme was implemented. It also shows that the rejection of certain genuinely virtuous nominees and the recruitment of some candidates who had exhibited objectionable conduct somehow compromised the emperor’s ideal. This analysis is followed by a discussion of the political and social implications of the scheme. Instead of perceiving this promotion channel as a means for Huizong and Chief Councilor Cai Jing to eliminate dissidents and install ideological conformity, the author argues that the scheme was an initiative of the emperor to counter the chief councilor’s dominance and alleviate factional conflicts. The final section examines the extent to which this scheme facilitated social mobility in the Song dynasty.  相似文献
