A state law has placed an obligation on the criminal investigation laboratories to screen and quantitate all preparations, both pharmaceutical and illicit, that fall under the provisions of "Excepted Substances." Without complete screens on these preparations, there is room for erroneous indictments as well as possible acquittals on technicalities. 相似文献

While several studies have probed the determinants of public support for government funding of arts and culture in the United States, little work to date has addressed the question in Europe. Yet as private cultural funding increases in magnitude in most Western European countries, the answer to this question has policy implications. This article formalizes the theory of the determinants of this public support in a model, employs public opinion data from Spain to estimate this model, and compares the results with those from the U.S. I find that support in Spain increases strongly with age, but is insignificant in most other variables. The article's empirical results yield several lessons for cultural policy design. 相似文献

In comparative analysis of welfare states, there is a consensus that mature welfare state systems have been confronted, for some considerable time, with substantial pressure towards re-structuring and that, as a result, they actually have undertaken several and varied modifications. This articles aims at exploring and analysing these developments in Austria and Germany from a comparative point of view. The analysis concentrates on two vital fields of social policy: old-age insurance and unemployment insurance. Especially in respect of the development of social policy and regarding important characteristics of the two welfare state systems, both countries traditionally show a large degree of resemblance to each other. Many similarities remained to exist during the phase of growing pressures on the welfare state, whereas at the same time it is evident that differences between the two countries increased. The respective actual developments will be interpreted in the light of corresponding theories of comparative welfare state research and classified as gradual and structural changes. 相似文献

Administrative data from North Carolina are used to explore the extent to which that state's relatively sophisticated school‐based accountability system has exacerbated the challenges that schools serving low‐performing students face in retaining and attracting high‐quality teachers. Most clear are the adverse effects on retention rates, and hence on teacher turnover, in such schools. Less clear is the extent to which that higher turnover has translated into a decline in the average qualifications of the teachers in the low‐performing schools. Other states with more primitive accountability systems can expect even greater adverse effects on teacher turnover in low‐performing schools. © 2004 by the Association for Public Policy Analysis and Management. 相似文献

Advocates of regulatory relief propose a budget that would annually cap regulatory costs. But emulating fiscal budgeting would be much more difficult than they envision. An arbitrary macrobudgetary constraint would have to be selected, and the potential scope of the regulatory budget would be vast. The process of regulatory budgeting would be very-time consuming, and could increase micromanagement by the Congress. Estimating regulatory costs would be challenging, and ignoring regulatory benefits would be unfair and inefficient. A preferable alternative to regulatory budgeting would be to expand the Government Performance and Results Act to include cost-effectiveness reviews for regulations. 相似文献

Local Context and Democratization in Mexico 总被引:2,自引:0,他引:2
While democratization is often seen as a national-level process, we argue that there is important scope for local effects. Through analysis of Mexican public opinion data collected on the eve of that country's historic 2000 elections, we demonstrate that local context greatly affects evaluations of the legitimacy of the system, and these evaluations, in turn, help to shape the willingness of citizens to engage with the system. Citizens are more willing to participate in politics if they think the process is fair, and direct evidence of the fairness of the system is provided by the local political context. This local connection, then, becomes critical in the process of individuals becoming, in Almond and Verba's classic term, "participatory" citizens (1963). 相似文献

In 1989, the combination of art, religion, homosexuality, ana1 public dollars set off an explosive two-year battle and a decade of skirmishes over funding for the National Endowment for the Arts. To promote artistic freedom and to avoid political controversy, federal arts policy delegates specific funding decisions to private donors and arts professionals. In an era of morality politics—hot-button issues driven by deeply held beliefs rather than by expertise—that strategy no longer works. Artists, donors, and arts audiences diverge widely from the rest of the American public in their attitudes toward religion, sexual morality, and civil liberties, as General Social Survey data show. Delegating funding decisions to them has naturally led to some subsidies of art offensive to important segments of the population. 相似文献
