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

Extraction and analysis of human nuclear and mitochondrial DNA from electron beam irradiated envelopes 总被引:1,自引:0,他引:1
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

European parliamentary committee systems play an important role in organising the work of legislatures so as to assure the parliamentary leadership of its agenda. At the same time, the strategic positioning of committees in the legislative process provides opportunities for chairs to potentially undo the will of the leadership. We consider the degree to which committees in the Lithuanian legislature serve the private interests of legislators or those of the parliamentary leadership. We argue that while committees most often assist the leadership in obtaining preferred legislative outcomes, chairs on occasion have been able to change proposals or even frustrate the parliamentary leadership of governing coalitions. 相似文献

Police organizations function in a dynamic environment that requires management to make adjustments to constant changes. The
focus of this paper is on entry-level uncorrected vision entry standards that are being affected by recent technological advancements
in the optical field. Extreme policy variances exist relative to - these requirements and many of the more rigid policies
are grounded in unrealistic foundations. Many of these foundations relate to problems relevant to spectacles. Additionally,
these standards are based on very remote events. An analysis of these policies and policy recommendations are presented in
this paper. 相似文献
