Since their creation under the auspices of the United Nations Educational, Scientific and Cultural Organization (UNESCO) Man and the Biosphere (MAB) Program in 1976, biosphere reserves have provided an international framework for linking protected areas with their associated working landscapes. In Australia, twelve biosphere reserves were added to the World Network between 1977 and 1982. That initial flurry of activity has been followed by twenty-five years of limited interest and development in biosphere reserves in this country, although evidence suggests that new energies are being directed to it. After sketching the origins of the biosphere reserve concept and its central tenets, we explore those environmental, cultural and institutional factors that may be promoting renewed interest in the program. We then review the initial implementation and current status of the Australian Biosphere Reserve Program. Factors supporting the limited success that exists in the program in Australia are highlighted, and the new form of biosphere reserve is illustrated with reference to Australia's recent and only urban biosphere reserve, at the Mornington Peninsula, in the state of Victoria. We speculate that prospects for biosphere reserves in Australia are brighter because of the provision for biosphere reserves under the Commonwealth of Australia's Environment Protection and Biodiversity Conservation Act (DEH 1999), the conceptual relevance of the biosphere reserve to bioregional and catchment management more generally and the continued success of existing model biosphere reserves.  相似文献

In order to investigate replicability in scoring linear enamel hypoplasias 59 anterior teeth were evaluated by three observers. Hypoplasias were identified with low-power microscopy and by the unaided eye. Location on the tooth was determined through caliper and micrometer measurement as well as assignment to tooth ‘thirds’. Hypoplasia size was determined through measurement of episode width and comparison with a cast designed to categorize types of hypoplasia severity. Intra-observer analysis showed consistent scoring of about 65 per cent of individual hypoplasias between rounds, with high replicability in episode location, size and severity using all methods tested. Inter-observer error was similarly low for episode size and location, but consistent scoring of individual hypoplasias between observer pairs ranged between 21 and 39 per cent. It is likely that the most important factor in the low level of replicability is the slight size of the majority of hypoplasias involved. Thus, the results suggest that further work should be directed toward developing the minimum threshold for scoring episodes. Other issues include measures to control ‘drift’ in scoring procedures over time, and procedures to score large cervical hypoplasias in canines, which can appear as multiple episodes with magnification. Among the various scoring methods tested, determination of episode location was highly replicable using all three techniques. Episode width was also highly replicable using the micrometer, but the cast association proved less successful.  相似文献

Starting from questions about the nature of cultural diversity, this paper examines the pace and tempo of change and the relative importance of continuity and discontinuity. To unravel the cultural project of the past, we apply chronological modelling of radiocarbon dates within a Bayesian statistical framework, to interrogate the Neolithic cultural sequence in Lower Alsace, in the upper Rhine valley, in broad terms from the later sixth to the end of the fifth millennium cal BC. Detailed formal estimates are provided for the long succession of cultural groups, from the early Neolithic Linear Pottery culture (LBK) to the Bischheim Occidental du Rhin Supérieur (BORS) groups at the end of the Middle Neolithic, using seriation and typology of pottery as the starting point in modelling. The rate of ceramic change, as well as frequent shifts in the nature, location and density of settlements, are documented in detail, down to lifetime and generational timescales. This reveals a Neolithic world in Lower Alsace busy with comings and goings, tinkerings and adjustments, and relocations and realignments. A significant hiatus is identified between the end of the LBK and the start of the Hinkelstein group, in the early part of the fifth millennium cal BC. On the basis of modelling of existing dates for other parts of the Rhineland, this appears to be a wider phenomenon, and possible explanations are discussed; full reoccupation of the landscape is only seen in the Grossgartach phase. Radical shifts are also proposed at the end of the Middle Neolithic.  相似文献

THE PLEASANCE AT Kenilworth Castle was a ‘vividarium’, or pleasure garden, constructed by Henry V in the early 15th century. Despite academic recognition and the survival of well-preserved earthwork remains, the Pleasance has never previously been subjected to a programme of detailed archaeological survey and investigation. This article discusses the results of a new analytical earthwork survey undertaken by staff from English Heritage in 2012. It considers the contribution that these new findings make to wider debates on medieval designed landscapes, with a particular focus on mobility and its role in unlocking the meaning and symbolism embedded in elite landscapes.  相似文献
