Since its beginnings, zoning has been at its core a tool for achieving exclusionary objectives. Judge Westenhaver, who wrote the lower court decision in Ambler Realty Co. u. Village of Euclid, 297 Fed. 307, 316 (N.D. Ohio 1924) invalidating the village's zoning ordinance, observed that its purpose “is really to regulate the mode of Living of persons who may here-after inhabit [the village]. In the last analysis, the result to be accomplished is to classify the population and segregate them according to their income or station in life.” In reversing his decision, Justice Sutherland classified apartments as “mere parasites … which would deprive children of the privilege of quiet and open spaces for play, enjoyed by those in more favored localities,” In effect, he held that the state's police power could be used to create different levels of health, safety and genera1 welfare for different classes of people. One level was adequate for the poor and another level could be enforced at the behest of the rich who could afford to buy homes in single-family, low-density districts. Even Justice Douglas, a most unlikely bedmate for Justice Sutherland, reflected the same attitude when he wrote recently.  相似文献

Recent decades have seen growing historical interest in “second rank” officials who, whilst they do not play a leading role in government or political movements, can influence the way decisions are shaped and executed. At the same time, the interest of scholars in American policy during the Vietnam War shows no signs of abating. This article investigates the experience of one second rank official during the war, David Bruce, who was Ambassador to London during 1961–1969. Making particular use of Bruce's extensive diaries, it traces his shifting views on the war, looks at the extent to which he shared the outlook of other official,s and asks what influence, if any, he had on events. It argues that, whilst he always remained loyal to his own government and often mirrored the outlook of the Johnson Administration, Bruce had his own perspective on events, was consistently critical of American tactics on the ground, and, in Spring 1967, influenced by Robert McNamara, became an early advocate of retrenchment.  相似文献

In this article, we present findings from a grant-funded initiative to replace traditional, proprietary textbooks with an open content textbook under a Creative Commons license in the introductory American government course (POLS 1101) at Middle Georgia State University. We find that the use of an open content textbook led to somewhat negative effects on student learning outcomes and student course satisfaction, although the associated lower textbook cost increased textbook accessibility to students. We conclude with some suggestions to those adopting textbooks in this course and to the wider discipline regarding measures that may lead to more unequivocally positive outcomes than those experienced in this study.  相似文献
