Bureaucratic Job Mobility and The Diffusion of Innovations   总被引:1,自引:0,他引:1  
In studies of innovation, policy entrepreneurs recognize latent demand for new policies and then expend resources to promote them. But studies of policy entrepreneurs have generally focused on the demand for innovation, while neglecting the supply side of policy entrepreneurship. This article argues that bureaucratic labor markets affect the emergence of policy entrepreneurs, and so affect the diffusion of policy innovations across local governments in the United States. Analysis of a survey of municipal police chiefs and water utility managers relates governments' hiring and promotion policies to their adoption of professionally fashionable innovations. Agency heads who advanced to their current positions diagonally (arriving from another organization) are more likely to initiate these innovations than are agency heads who were promoted from within. Bureaucratic policy entrepreneurs emerge where government demand for innovation meets a supply of mobile administrators, who carry the priorities of their professions into the agencies that they serve.  相似文献

A stratified random sample of thirty-three female robbers incarcerated at the Florida Correctional Institute at Lowell was selected and interviewed. The findings indicated that the majority of the sample was black, under thirty, of average intelligence, and single. The female robber was typically found to operate with an accomplice, use a firearm, and be motivated by a desire for financial gain. A preliminary typology that included two major categories, situational robbers and career robbers, was developed.  相似文献

In this article the authors present some preliminary findings from a comparative study of police recorded violent crimes in Stockholm and Basel. They present the first results from a comparative analysis of the situational context, the ecology of crime, and of offender residences in these cities. There is impressive evidence of basic similarities in the situational context of violent crime and the residential distribution of violent offenders. Yet there are also significant differences, some of which may have interesting implications for crime prevention. Firstly, violent crime seems to be more highly concentrated during weekend nights in Stockholm than in Basel. Secondly, they find evidence that the presence of weapons in a community increases the risk of more serious outcomes of violent events. Efforts to reduce the availability of weapons may thus have significant effects on the outcomes of violence, but not necessarily on its frequency. Thirdly, they show that offenders in both cities are highly concentrated in socially disorganised communities with few economic and social resources.  相似文献

Haplotype data were obtained from a sample of 777 unrelated male individuals from Antioquia Department (Colombia), for eight Y-chromosome STRs (DYS19, DYS385, DYS389 I, DYS389 II, DYS390, DYS391, DYS392 and DYS393). A total of 442 different haplotypes were identified of which 334 were represented only once in the database and the most frequent haplotype was found in 32 individuals. A high haplotype diversity was found (99.45%). Genetic distances were calculated using previously published haplotype data and the lowest values were found for the comparisons with samples of lberian origin.  相似文献
