Cultural resource management (CRM) work accounts for most of the archaeology conducted in the United States. A diverse and
somewhat fragmented field, CRM has nonetheless achieved a degree of institutional and organizational maturity. CRM archaeology
has produced important contributions to archaeological methodology and has established and refined knowledge of regional cultural-historical
sequences and settlement and subsistence patterns. The current florescence of historical archaeology is attributable to CRM.
Yet the maintenance of high quality in CRM is a pervasive and enduring problem. Academic institutions need to reestablish
alliances with the CRM community. The future viability of CRM archaeology depends on factors both internal and external to
the discipline: regulatory and statutory “reform,” agency funding levels, looting and other destructive forces, and Native
American and other public involvement. 相似文献

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

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

In the last decade, conversations around queering of GIScience emerged. Drawing on literature from feminist and queer critical GIS, with special attention to the under‐examined political economy of GIS, I suggest that the critical project of queering all of GIS, both GIScience and GISystems, requires not just recognition of the labour and lives of queers and research in geographies of sexualities. Based upon a queer feminist political economic critique and evidenced in my teaching critical GIS at two elite liberal arts colleges, I argue that the “status quo” between ESRI and geography as a field must be interrupted. Extending a critical GIS focus beyond data structures and data ethics, I argue that geographic researchers and instructors have a responsibility in queering our choice and production of software, algorithms, and code alike. I call this production and choice of democratic, accessible, and useful software by, for, and about the needs of its users, good enough software. 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
