High-resolution stable oxygen isotope analysis of the bivalve Saxidomus gigantea from shell midden sites was applied to identify seasonal patterns of resource procurement on the central coast of British Columbia, Canada. A total of 90 archaeological shells were examined from eight distinct sites spanning a 4500-year period. Combining micro-growth pattern analysis with high-resolution stable oxygen isotope sampling allows for a precise season of collection to be determined in estuarine bivalves recovered from archaeological sites. The results of the stable oxygen isotope analysis provide insights into seasonally structured harvest of S. gigantea (butter clam), which is associated with different types of sites. The results show a variety of patterns, including multi-seasonal collection, intensive seasonal harvesting and casual, supplemental use of butter clams at different locations. 相似文献

Abstract Theory is not a goal in itself but a means of enriching the history of cartography by stimulating new research questions and objectives. In this paper the concept of ‘transparent maps’ (carriers of an image of the external reality of the world) and ‘opaque maps’ is introduced. The notion is approached structurally (standards of graphical representation, drawing, geometry, text); through the sociology of the map (map makers, institutions, the public); and through seeing maps in their cultural and historical context (an approach which raises issues of the definitional boundaries of the history of cartography and which is arguably one of the most stimulating perspectives today as fostered by, in particular, contributors to the History of Cartography). Finally, attention is drawn to three important topics for the research agenda: the links between maps and culture; maps as a language of communication and as instruments of power; and the links between perception, logic and mnemonics. 相似文献

Seven selachian scale types are described from the middle Cenomanian Moonkinu Formation, outcropping on the southern shores of Bathurst Island in northern Australia. The scales are classified in accordance with previously published scale morphologies of Cretaceous and modern sharks, and are representative of the Orders Squatiniformes (Family Squatinidae), Carcharhiniformes (Family Scyliorhinidae), and Lamniformes (Family Odontaspididae). The presence of typically bottom-dwelling, shallow-water angelsharks (squatinids), catsharks (scyliorhinids), and sand tiger sharks (odontaspidids) within the Moonkinu Formation support an inner neritic depositional environment interpretation for the unit, previously determined from foraminiferal biofacies and lithology. The biostratigraphic potential of these scales can only be assessed after scales from more Cretaceous localities are described and documented. 相似文献

Many believe that Amazonian communities could benefit from the growing market for timber through self‐governed approaches to forest management. However, there is no clear understanding of how communities are to develop such approaches given logging frontiers that are characterized by informal negotiations with loggers and community forestry initiatives that are promoted by development agents. This article reports on research from four study areas in Bolivia, Brazil and Peru which reveals that external players exercise considerable power over communities. First, loggers and development agents impose forest management schemes directly on communities, hindering them from developing their own approaches. Second, paternalistic relationships with loggers and development agents prevent communities from identifying common interests and expressing these through their representative organizations. Finally, loggers and development agents use powerful discourses to shape acceptable schemes in forest management, silencing communities’ voices in debates. Through these different power mechanisms, external agents thwart the emergence of self‐governed community management approaches. 相似文献

In order to accommodate the recent enlargements of the European Union (EU) there has been considerable changes to the operation of EU regional policy which means that Scotland along with other regions in the EU-15 will receive considerably less money from the Structural Funds in the future. This article discusses the extent to which the reduction in EU funding for economic development will impact on the Scottish economy. The issue is explored by considering the contribution, which Structural Funds have made in the past to economic development in Western Scotland, which has received the lion's share of the money allocated to Scotland. It is suggested that whilst the amount of economic development in Scotland will not be significantly reduced as a result of the decline in EU funds the types of projects and organizations receiving funding will alter because of changes made to the way in which the funds are administered in Scotland. 相似文献
