Civic engagement and collaborative public management are concepts that are defined broadly, making theoretical explication challenging and practical application of empirical research difficult. In this article, the authors adopt definitions of civic engagement and collaborative public management that are centered on the citizen and the potential for active citizenship. Following a historical review of civic engagement in the United States, a conceptual model of five approaches to civic engagement is offered. Citizen-centered collaborative public management is enhanced through these approaches. The authors suggest the need for further empirical research on collaborative public management that is grounded in citizenship action.  相似文献

The United States Postal Service is considering methods such as electron beam irradiation to neutralize biological agents sent through the mail. While this is proven to reduce/eliminate pathogenic organisms, it may also degrade human genomic DNA and therefore hinder the ability to garner forensically informative genetic profiles. To determine the effects of electron beam irradiation on DNA typing, 16 white, standard letter-sized envelopes were licked. Half of the envelopes served as nonirradiated controls while the other half underwent irradiation at dosages sufficient to kill anthrax spores (29.3 and 51.6 kGy). Total cellular DNA was extracted from all envelopes; nuclear short tandem repeat loci, as well as the hypervariable region I from mitochondrial DNA, were amplified by means of the polymerase chain reaction. Short tandem repeat profiles and mitochondrial DNA sequence haplotypes were acquired on an ABI Prism 310 Genetic Analyzer platform. Analysis of data from irradiated samples revealed evidence of DNA degradation; however, the ability to construct full genetic profiles from both nuclear and mitochondrial DNA remained largely unaffected. The use of the polymerase chain reaction, coupled with florescent fragment analysis and mitochondrial DNA sequencing, should be considered to profile biological material from evidence enduring irradiation to inactivate infectious agents.  相似文献

Abstract Despite considerable interest in comparative fiscal policy in general, and the high salience of tax policy and tax reform in the industrialized democracies, there are relatively few cross–national studies of the economic and political correlates of revenues over time. We undertake a cross–national time series study of revenue growth in fourteen OECD countries between 1958 and 1990.We test a number of political and economic hypotheses about revenue change, including political business cycle, 'fiscal illusion', elasticity, and ideological theories. For the 1958—1990 period, we find that all countries, regardless of revenue structure, experience higher real revenue growth as a result of inflation, but that revenue growth is more responsive to unemployment in countries that rely more on direct taxes compared to countries with less direct–tax reliance. We find that this effect is most pronounced in the post–1972 period. We also find that revenue tends to increase in the years following elections, consistent with the idea that governments try to minimize the political fallout from tax increases by separating them as much as possible from election campaign periods; this effect, too, is most pronounced in the post–1972 period. We find no support for 'fiscal illusion' and ideological theories of revenue growth.  相似文献

State legislatures in the United States engage in a substantialamount of international activity. In the 2001-2002 legislativesessions, some 886 bills and resolutions with significant internationalimplications were introduced. Approximately 306 of these wereadopted. This level of international activity has increasedsubstantially since 1991, and the substantive focus has changedover time. In addition, about half of all state legislaturesreceived at least one foreign delegation and sent at least onedelegation of members abroad in the last session. As in mostareas of state policy, there is considerable interstate variationin legislatures' international activities. Some states had virtuallyno international legislative activity, whereas others were veryactive. The principal factors explaining this variation werethe degree of state involvement in the international economy,as measured by the level of state exports, and party controlof the legislature.  相似文献
