The remains of a ditched field system dating from the late Iron Age to the early post-Roman period, and two associated corn drying ovens (dating to the 5th–6th centuries AD) were revealed during archaeological excavations at Goldthorpe, South Yorkshire. The site was excavated during 2012 and 2013, during which bulk environmental samples were taken in order to retrieve any surviving botanical remains from deposits associated with the corn drying ovens, and other features across the excavated area. Early post-Roman occupation is under-represented in the archaeological record, especially in northern England, as such human activity and subsistence during this period are currently not well understood. This paper combines evidence for the field system, the physical remains of the corn drying ovens and their associated botanical remains to further understand early post-Roman change and continuity in landscape use and crop production and processing practices. 相似文献

Few Indigenous peoples have control over their heritage, despite international recognition of this right in the United Nations Declaration on the Rights of Indigenous Peoples, adopted by the UN General Assembly in 2007. In Ontario, Canada, the Ontario Heritage Act, R.S.O. 1990 regulates archaeology and grants licences to archaeologists to investigate archaeological heritage. Indigenous people want more control of their archaeological heritage in Ontario. To uphold Indigenous rights to archaeological heritage in Ontario, heritage legislation and policy needs to be revised and site protection increased. This paper recommends that Indigenous archaeological heritage in Ontario would be best protected by strengthening Ontario government land development policy and legislation to require the free, prior, and informed consent from affected Indigenous communities before removal of significant archaeological sites and remains from their ancestral territories. 相似文献

On 13 March 1979, the first unconstitutional change of power in the Eastern Caribbean occurred in Grenada, a member of the Commonwealth, when the radical New Jewel Movement overthrew Prime Minister Eric Gairy. This article examines the policy of the British government towards the new People's Revolutionary Government (PRG) during the first month of the ‘revolution’. It demonstrates that in contrast to the alarmist reactions of some of Grenada's neighbours, and the United States' intense concern about the PRG's pro-Cuban leanings, British policy was more optimistic and relaxed and designed to ‘keep a line open’ to Grenada. 相似文献

Scholars agree that postreform House majority leadership strategies distinguish contemporary leaders from their predecessors. One such strategy is leaders' use of media to fulfill personal and member goals. Commonly presented evidence of this strategy is the increase in the number of times leaders appear in national evening newscasts. Yet most studies do not investigate the kind of media coverage leaders receive over time. Hence they do not show whether leaders have been successful in generating the sort of television attention consistent with the incentives that the literature identifies as driving them to adopt a media-oriented strategy. This article begins to address this gap in our understanding. Conducting a content analysis of network news accounts, we find that while postreform leaders have received more attention than their predecessors, coverage of them declined and leveled off in the 1990s. We also find that despite the drop in levels of attention accorded House majority-party leaders, they have maintained a plateau of higher news visibility relative to their primary competitors in the House, committee chairs, though there have been some recent exceptions to this trend that are highly suggestive. 相似文献
