“Beggar thy Neighbor:” Testing for Free Riding in State-Level Endangered Species Expenditures 总被引:1,自引:0,他引:1
An important public policy question that remains unresolved iswhether devolution will enhance sensible policy making byexploiting informational asymmetries or, instead, trigger a``beggar thy neighbor'' response and stimulate free ridingamongst localities. We analyze this question within theframework of U.S. environmental policymaking by scrutinizing aunique panel data set on state-level endangered speciesexpenditure patterns. Our empirical estimates are consistentwith the notion that states free ride, which may lead to anexpenditure equilibrium that is not Pareto efficient. 相似文献

An Empirical Study on the Relation Between the Critical Angle for Bullet Ricochet and the Properties of Wood 下载免费PDF全文
Wim Kerkhoff Ivo Alberink Ph.D. Erwin J.A.T. Mattijssen M.Sc. 《Journal of forensic sciences》2015,60(3):605-610
The properties of a bullet, an object, and the incidence angle determine whether the bullet will penetrate, perforate, or ricochet. In this study, the critical angle for ricochet was established for .32 Auto and 9 mm Luger bullets on Abachi, Southern Yellow Pine, Beech, and Ipe wooden boards. Results show that the critical angle differs depending on caliber and wood type. The critical angle is higher for .32 Auto bullets than for 9 mm Luger bullets and increases with increasing wood density and Janka hardness. The established critical angles for ricochet on the lightest and softest wood (Abachi) are 10.4° and 10.3° for .32 Auto and 9 mm Luger, respectively. For the heaviest and hardest wood (Ipe), the angles were 45.0° and 33.4°, respectively. The combined results on the four tested woods show a strong linear relationship between both the density and the hardness and the critical angle for both calibers. 相似文献

Erwin C. Hargrove 《Policy Sciences》1971,2(3):229-247
New kinds of policy analysts and policy scientists are being trained in university graduate programs but the outlines of this new profession remain fuzzy. A comparative analysis of other professionals in government advisory roles may provide touchstones by which to develop the new profession. The article reports interviews with urban planners, lawyers, economists and political scientists about their experience in government. Propositions are developed about characteristic modes of thought and problem-solving styles of each profession and conclusions drawn about the relative effectiveness of each set of professional skills in a policymaking process. It is then suggested that the new policy scientist profession should develop some of the positive skills of the other fields in order to enhance effectiveness. 相似文献
