The utility of oral history has always seemed most evident whengreat change occurs. Political, social, and cultural upheavalscall for documentation of the direct participants, and the printedarchives inevitably reflect the viewpoint of the old regime.Nowhere has such change been more dramatic and breathtakingthan in South Africa since the 1990s, when decades of strictapartheid collapsed into a multiracial, multicultural societythat is now ruled by its former political prisoners.

Lithic artifacts from the lowest strata of the Debra L. Friedkin site, located on Buttermilk Creek in central Texas, have been interpreted as an undisturbed pre-Clovis assemblage (Waters et al., 2011a). Stone tools and debitage were recovered from sediments stratified just below diagnostic Clovis artifacts and dated by OSL to between 13.2 and >15.5 cal kya. Invoking commonly observed cultural and natural site formation processes, we offer an alternative explanation of the “Buttermilk Creek Complex” as a Clovis assemblage in secondary association with the dated sediments. 相似文献

On the 25th Anniversary of the founding of the first Industrial Estate in Dundee this article reviews the industrial development of the city in the post‐war period and identifies the problems of two sectors of the city's industry, the traditional Jute industry and the modern estate based industries. The friction between the two in their post‐war development, and the effects of the change of emphasis in the city's industrial structure during that period, on the demographic and social geography of the city are also discussed. The article concludes with an outline of the possible lines of development for industry in Dundee, with reference being made to present Government economic planning policies for Scotland. 相似文献

Soil investigations have been carried out at an Iron Age farm site lying under natural vegetation. The soils of the area were mapped and described, and soil samples analysed for pH, organic carbon, total nitrogen, acid‐soluble phosphorus, and available sodium, potassium, calcium and magnesium. Two soil types were distinguished on the mineral soils ‐ Brown Podzolic Soils and Iron Humus Podzols. The former are associated with a higher pH, higher phosphorus contents, and a lower carbon‐nitrogen ratio. These differences arc difficult to explain by natural causes, and arc ascribed to cultivation and manuring of the soil during the occupation of the site. 相似文献

In the Cantigas de Santa María, King Alfonso X unveils an intricate cultural, political, and economic system that defines the relationship between Christian society and religious minorities. This article illustrates that the Cantigas must be understood as an ideological instrument of cultural codification that reaffirms the established Christian social order in relation to three principal groups: heretics, Jews, and Muslims. 相似文献

Resort-hotel location has diffused from the Northeast and Midwest to the Sunbelt and West. In 1985 there were approximately 834 resort hotels and 295,617 resort-hotel rooms in the United States. More than half of these rooms were located in just three states: Florida, Nevada, and Hawaii. The present distribution of resort-hotel rooms has been influenced by three periods in resort-hotel evolution. Until the early 20th century, resort hotels were in the tradition of the “Grand Hotel,” oriented toward natural resources in the East and Midwest and serving an elite clientele. Later in this period, elite resorts were also developed in the coastal Southeast and in the Southwest. A second, transitional period beginning in the 1920s accelerated construction of resort hotels in the Southwest and along the Southeastern coast. In the third period, post World War II mobility and affluence led to a revolution in resorthotel location and function. Resort hotels are now found in urban and suburban locations and have expanded the resort concept by linking it to meetings, conventions, and business travel. This has allowed resort hotels to adapt to changing market conditions and to achieve economies of scale by spreading demand throughout the year. 相似文献
