Summary.   Archaeologists have identified the adoption of new forms of cremation ritual during the early Roman period in south-east Britain. Cremation may have been widely used by communities in the Iron Age, but the distinctive nature of these new rites was their frequent placing of the dead within, and associated with, ceramic vessels. This paper suggests an interpretation for the social meaning of these cremation burial rites that involved the burial of ashes with and within pots as a means of commemoration. In this light, the link between cremation and pottery in early Roman Britain can be seen as a means of promoting the selective remembering and forgetting of the dead.  相似文献

Household CO2 emissions are a significant contributor to global greenhouse gas emissions and consequently climate warming. Despite this, there has been little consideration of how household CO2 emissions may be affected by changes in climate. The aim of the present study has been to investigate the way climate, as well as socio‐demographic characteristics, may affect household CO2 emissions produced from energy use. A national online survey was conducted to determine current household CO2 emissions in Australia as well as capture the ownership and use of household appliances and installations. Electricity and gas‐based emissions as well as the ownership of a variety of household appliances and installations were found to be strongly associated with temperature. Electricity and gas emissions were found to decrease as annual average temperatures increase. However, as temperatures continue to rise under climate change this pattern may be reversed owing to increased reliance on air conditioners. One option for preventing this from occurring is to encourage houses to adopt more solar‐passive installations. Although this may be expensive, households with higher emissions tend to have higher incomes, indicating that they may have the capacity to pay for such installations.  相似文献

It often goes unmentioned that one of the primary purposes of the famous circumnavigation of H.M.S. Beagle was foreign missions. Charles Darwin, the voyage's most famous participant, was at best noncommittal about the missionary activity surrounding him for most of the trip. He emerged from the voyage, however, as an enthusiastic and outspoken proponent of missions. The British missions at Tahiti prompted him to change his view. Sailing to Tahiti, he read several accounts about the South Sea missions, and had already begun making arrangements to publish his “Diary” as a travel journal. Darwin became convinced that missionaries helped “advance” the natives toward “civilization” and thereafter enthusiastically defended missionaries in an ongoing public debate.  相似文献

The UN is approaching its seventieth birthday in 2015. Kofi Annan, its seventh secretary general, and the only incumbent not to have come from a national government, has written the most honest and insightful memoir of any occupant of the thirty‐eighth floor, Interventions. Despite terrible setbacks in Bosnia and Rwanda, the United Nations remains the most representative and successful international organization in history. As Mark Mazower points out in his Governing the world, an acutely penetrating history of international governance, the successes of the UN are more than the founders of the ill‐fated League of Nations could have dreamt of. Mazower's tour de force combines a history of the intellectual ideas of the nineteenth and twentieth centuries and their eventual realization in the League of Nations and the UN. While his conclusions question whether faith in international institutions has been lost, the reality of universal membership of the UN and establishment of an International Criminal Court might suggest otherwise.  相似文献

EXCAVATIONS AT the castle complex of Cēsis, Latvia, uncovered an unusual find of large quantities of horse bones, some of which were partially articulated, along with equestrian equipment. These were associated with a destroyed building at the edge of the southern outer bailey. The horses included large males, most probably stallions, and pathology on several of the recovered vertebrae suggests these individuals had been used for riding. The size of the horses was within the range for medieval war horses, and the associated tack also pointed to prestigious riding animals. Radiocarbon dating of the bones placed them firmly within the Teutonic Order's period of rule. We conclude here that these horses fulfilled a military role in the final decades of the Teutonic Order’s rule in Livonia in the late 15th/early 16th century and that the better-known equestrian culture of late-medieval Prussia was comparable in character, if not in scale, to that in Livonia.  相似文献
