Scholarship concerning the lives of enslaved African Americans in southern New England has shifted rapidly from outdated models of acculturation to conflict-driven models of domination and resistance. With the assumption of conflict as the outcome of all power relations, both economic production and historical contextuality have been overlooked, with slavery systems in New England simply equated with other regions of the Atlantic world, rather than compared and contrasted. This essay reconsiders contests over power in seventeenth- and eighteenth-century New England. Drawing on the work of Greene (1966), Piersen (1988), and others, I argue that the system of slavery in the region may represent an anomalous case in terms of the means of control or the means of resistance. By examining demographic patterns, economic production, and agricultural landscapes in Rhode Island's East Bay, I argue that there may be more to be learned from William D. Piersen's (1988, p. 143) concept of resistant accommodation as a middle ground between the two extremes of the theoretical spectrum. The essay concludes with suggestions for further research on the archaeology of African-American lives in the region.  相似文献

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

Recent Paleolithic work along the middle Enisei River of central Siberia has revealed a long history of occupation that almost certainly begins in the Middle Pleistocene. Although the evidence for the Lower Paleolithic is somewhat tentative, there is good reason to believe that hunter-gatherers had periodically occupied the middle Enisei before the last interglacial. The steppe environment of the region during the Upper Pleistocene was relatively bountiful; more than 200 Upper Paleolithic sites, both before and after the Last Glacial Maximum, have been located. The region appears to have been abandoned during the Last Glacial Maximum. Most of Soviet and Russian archaeological work has been guided by a cultural–historical orientation, but recently there has been increased interest in developing adaptationist and ecological research strategies. The middle Enisei and the wider central Siberian region are key to understanding early adaptations to the north and the dimensions of Paleolithic population movements.  相似文献
