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

The Southern Indian Neolithic-Iron Age transition demonstrates considerable regional variability in settlement location, density, and size. While researchers have shown that the region around the Tungabhadra and Krishna River basins displays significant subsistence and demographic continuity, and intensification, from the Neolithic into the Iron Age ca. 1200 cal. BC, archaeological and chronometric records in the Sanganakallu region point to hilltop village expansion during the Late Neolithic and ‘Megalithic’ transition period (ca. 1400–1200 cal. BC) prior to apparent abandonment ca. 1200 cal. BC, with little evidence for the introduction of iron technology into the region. We suggest that the difference in these settlement histories is a result of differential access to stable water resources during a period of weakening and fluctuating monsoon across a generally arid landscape. Here, we describe well-dated, integrated chronological, archaeobotanical, archaeozoological and archaeological survey datasets from the Sanganakallu-Kupgal site complex that together demonstrate an intensification of settlement, subsistence and craft production on local hilltops prior to almost complete abandonment ca. 1200 cal. BC. Although the southern Deccan region as a whole may have witnessed demographic increase, as well as subsistence and cultural continuity, at this time, this broader pattern of continuity and resilience is punctuated by local examples of abandonment and mobility driven by an increasing practical and political concern with water. 相似文献

This paper presents a general view over the second reception of Aristotle's writings beginning after the first invasion of Western crusaders in Constantinople in 1204 and enforced after the fall of the Byzantine capital in 1453. After the turn of the century we observe a widespread commentary tradition of Aristotle's writings, particularily of his Ethics and Politics. Philipp Melanchthon became the leading figure in these ethical and political discussions. More than 53 of his works relating this which were printed within the 16th century are known. 相似文献

In 2006 a cast-iron coffin was discovered in an unmarked burial plot in Lexington, Missouri. A multifaceted investigation
was conducted to provide historical documentation and possible identification of the individual. The coffin is an early Fisk
Patent Metallic Burial Case. Osteological analyses indicate that the skeletal remains belong to a 20 to 30 year old white
female who consistently ate an omnivorous diet with significant amounts of C4 plants or seafood. Rib morphology and her burial
garments suggest she frequently wore restrictive clothing. No gross skeletal pathological lesions or trauma were observed
except for a patch of reactive bone and an atypical pattern of bone remodeling on the visceral surface of the sixth rib. Subsequent
bacterial DNA analysis of the ribs and sternum indicate the presence of tuberculosis infection. Although not conclusive, multiple
lines of evidence are consistent with the skeletal remains representing Elizabeth (Triplett) Stewart who died in 1854 of pulmonary
tuberculosis. This multidisciplinary research significantly contributes to the local history of Lexington, Missouri and provides
a likely identification of the deceased individual for the Stewart Family. 相似文献
