This paper examines changes in the location of ore-based steel-makingcapacity in the U.S. over the period 1974 to 1991 using data on each of the 45 ore-based mills that were in operation in 1974. We find that the geographic ddistributions of demand and of competition from minimills and imports were important in determining where capacity reductions occurred and which plants were closed. Technology in use at the plant also affected capacity adjustment. However, we find that regional variation in prices of raw materials were notimportant factors in determining where steel-making capacity was reduced.  相似文献

Aboriginal people have occupied northern Alberta since the end of the last ice age. For most of that time they travelled across the land by foot, producing complex networks of trails, many of which may have great antiquity. Aboriginal people also modified the landscape extensively by the use of controlled burning. Lastly, they are immersed in and “read” the land as places with multiple cultural meanings, which in turn helped shape their cultures and identities. Together, these elements indicate the existence of a series of overlapping cultural landscapes for which the cross-country trails and waterways provide the grid. This article addresses the importance of traditional trails for identifying the cultural landscapes of northeastern Alberta and points to the rapid disappearance today of knowledge about such trails. It considers how archaeological investigations done in Alberta for Impact Assessment purposes fail to consider either trails or cultural landscapes in their surveys or to consult with Aboriginal people. As a result, government Review Panels making recommendations for whether or not an industrial project should be approved are basing their findings on incomplete information about Aboriginal land uses and meanings.  相似文献

Examining Charles II's changing posthumous reputation from his rumored deathbed conversion to Catholicism through the political upheaval of the late-seventeenth and early-eighteenth centuries demonstrates the profound effects affairs of state during the reigns of James II, William III, and Anne had on ideas of kingship. From elegists' depictions as the glory of the Stuart monarchy, Charles became James' feared counterpart during debates over the Copies of Two Papers Written by the Late King Charles II, and finally a distinctly human ruler. Published posthumous representations of Charles II suggest increasing willingness to consider kings as fallible men who made contestable decisions.  相似文献

In the central-southeastern area of Buenos Aires Province, Argentina, lies a mountainous area of low height in Tandilia that contains important outcrops of quartzite and granite. A large number of buildings are made of massive blocks of rock, some of them with a surface of over 1 ha. In addition to these completely artificial constructions are other structures that are semi-natural, having been made in places with special topographical characteristics and complemented with dry-stone walls. Scanty written documents allow us to attribute some of the constructions to an age before the permanent settlement of the Creole population. In the Tandilia Sierras these structures are commonly known as “corrales de indios” (Indian corrals). This designation involves a double prejudice with regard to function and cultural affiliation. Out of a total of 22 structures, we analyze a group of 4 that were excavated to use to review the written documents.  相似文献

This article reviews recent archaeological research on warfare in prestate societies of native North America. This survey comprises six regions: Arctic/Subarctic, Northwest Coast, California, Southwest/Great Basin, Great Plains, and Eastern Woodlands. Two lines of evidence, defensive settlement behavior and injuries in human skeletal remains, figure prominently in archaeological reconstructions of violence and warfare in these regions. Burning of sites and settlements also has been important for identifying the consequences of war and investigating more subtle aspects of strategy and directionality. Weaponry and iconography have to date provided important but more limited insights. Although considerable disparities exist between regions in the archaeological evidence for intra- and intergroup violence, all regions show a marked increase after A.D. 1000. These findings suggest that larger forces may have been responsible for escalating violence throughout North America at this time.  相似文献
