In the third book of Otia Imperialia (c. 1211), Gervase of Tilbury describes numerous wonders, among them an English belief regarding the Grant, a sparkling-eyed entity shaped like a bipedal foal, whose appearance racing through the streets forewarns of fire. This creature, attested to nowhere but in Gervase’s work, is something of a mystery for folklorists, who have tried to draw connections to other supernatural beings based on its name and its appearance. What has gone overlooked is the fact that the same elements of the Grant’s fire-omen belief existed well into the twentieth century in parts of England, albeit applied to hares. This article suggests that the Grant is an exaggerated hare, while exploring the larger topic of why it is that hares are so often associated with fire in European folklore. 相似文献

The long‐held redistributive function of agricultural cooperatives — one of moral economy and poverty alleviation — has changed dramatically as they emerge as core brokers for agro‐industrial development in the so‐called ‘green economy’. This article examines the changing role of cooperatives involved in brokering oil palm production and its impact upon the food security and livelihoods of smallholders who labour in plantation regimes situated in historically uneven agrarian political economies. Findings show how, increasingly, cooperatives reinforce uneven agrarian social relations of production and exchange in which indigenous smallholders experience loss of land, poor wage labour conditions tinged with insecurity and prejudice, and mounting debt in an expanding oil palm complex. The article suggests that these changes in agrarian social relations negatively influence indigenous farmers’ food security pathways, with their access to and use of appropriate foods diminishing. It asserts that understanding the impacts of cooperatives on food security pathways requires a relational and situated analysis of livelihood change and agrarian relations in extractive frontiers. 相似文献

This paper presents a review of the antiquity of periodontal disease, discussing past aetiological concepts in comparison to current research on the causes of this condition. As periodontal disease is analysable on dry bone specimens, it is possible to document its natural history. To date, little work has been done on an actual system of measurement for periodontal disease in such specimens. A new system of measurement is proposed, which is confined to evaluating the periodontal status of post-mortem skulls. The system is a modification of the Ramfjord index for periodontal disease (PDI) and can be adapted for both individual specimen measurement and for population studies. Seven skulls, ca. AD 500–700, from the Varden Site at Long Point, Ontario, were examined using the proposed system. Mean attachment loss was computed for each of the seven specimens. The results revealed one specimen with early periodontitis, four with moderate periodontitis and two with advanced periodontitis. This system provides a concise method for classification of the severity of periodontal disease in dry bone specimens that will be useful in documenting the history of this disease. 相似文献
