Using historical and numerical analysis and the five-part schema, this study finds that over the past 50 years structural modifications and adaptations by American cities have generally followed the standard S curve of the diffusion of innovation. In tests of Kaufman's and Hirshman's theories of epochs of change from representativeness to administrative efficiency, this study determines that mayor-council cities have, in a standard innovation diffusion S curve, adopted many of the key features of council-manager cities, increasing their administrative efficiency. At the same time, council-manager cities, again in an S curve, have adopted many of the key features of mayor-council cities, increasing their political responsiveness. Fewer cities are now either distinctly mayor-council or council-manager in form, and most cities are structurally less distinct, constituting a newly merged or hybrid model of local government—the type III city.  相似文献

Crime and security are major issues on a number of college campuses in the United States, yet little criminology research has been aimed at the campus setting. This article explores whixh aspects of the campus profile seem to contribute, or at least relate, to high levels of campus crime. A regression of crime rates on dimensions of the campus profile uncovered a number of correlates (specifically, measures of campus size and scholastic quality) in our sample of 222 colleges and universities. Somewhat surprisingly, the location of a campus—be it in an urban or a rural setting—had no impact on the level of its crime problem, though a slight influence on crime mix (proportion of crimes that are violent) was found.  相似文献

Twelve months ago the suggestion that Australia needed a Dictator was received with a tolerant smile. A Mussolini might suit the Latin psychology but the Australian sentiment would not stand for one. Today a large number of persons representing every side of our civic and commercial life agree that the suggestion is a sound one. The only question is “Who is the man?‘  相似文献
