Spatial Aspects of Capacity Change by U.S. Integrated Steel Producers

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.     

Die zweite Welle der Wiederaneignung des Corpus Aristotelicum in der frühen Neuzeit: die ethische und politische Tradition. Ein Forschungsbericht

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 16^th century are known.
