Using data describing the historical distribution of county seats in the United States, we (1) replicate the traditional ratio-variable test of the size-density law, (2) test a new multivariate, nonratio form of the law, and (3) introduce an alternative method of testing, one which avoids three possible problems in traditional analyses: ratio-variables, multicollinearity, and logarithmic transformation. 相似文献

Edward T. Linenthal 《The Historian; a journal of history》1995,57(4):687-694
Born in Boston, Massachusetts, in 1947, Linenthal earned his bachelor's degree in religious studies at Western Michigan University, his master's degree in divinity at the Pacific School of Religion, and his Ph.D. in religious studies at the University of California, Santa Barbara. He is Professor of Religion and American Culture at the University of Wisconsin, Oshkosh. His books include: Symbolic Defense: The Cultural Significance of the Strategic Defense Initiative (1989); Sacred Ground: Americans and their Battlefields (2nd edition, 1993); Preserving Memory: The Struggle to Create America's Holocaust Museum (1995); American Sacred Space (co-editor, 1995). He is writing a history of the A-Bomb controversy that will appear in a book to be published in 1996. Linenthal has often lectured about controversial historic sites for National Park Service staff. At the USS Arizona Memorial, Linenthal delivered a commemorative address on 7 December 1994, on the 53rd anniversary of the attack on Pearl Harbor. Linenthal and his wife, with their two sons, reside in Oshkosh, Wisconsin. Linenthal was the only historian to testify before the Senate Committee on Rules and Administration about the National Air and Space Museum's ill-fated exhibit, “The Last Act: The Atomic Bomb and the End of World War II.” What follows is Linenthal's Senate statement and comments he has written for The Historian. 相似文献

The need for experiments to study physical aspects of craft of the past is stated, as well as the necessity for them to have clear aims and to follow the established principles of scientific enquiry. These principles are discussed in this joint paper by ten maritime archaeologists and others, together with methods and some points of management critical to their application in this field. 相似文献

In the last two decades, many states established rail promotion programs in an effort to limit the contraction of their railroad networks. Now federal funds for rail projects are nearly exhausted, and states must decide whether to expand considerably their levels of internal funding for short line investments. Such a decision requires a careful articulation of policy goals, combined with sound cost-benefit techniques. Research shows, however, that states often fail to evaluate the full range of costs and benefits when considering rail investments. Instead, the economic development benefits of local rail service frequently are overstated, while the potential for rail investments to meet broader transportation planning needs is neglected. This paper evaluates the rationale behind state intervention in the rail industry, discusses the tendency of states to focus on economic development to the exclusion of other benefit categories, and presents summary results from an analysis of an investment project in North Carolina. The paper suggests that state funding for rail projects is more likely to be justified based on intermodal substitution benefits generated by local rail service, rather than the railroads' potential to increase jobs. 相似文献
