Regression analysis is used to test the effects of funding source (and of various control variables) on the importance of the article, as measured by the number of citations that the article receives. Funding source is measured by the number of private and the number of government grants mentioned in the acknowledgements section. The importance of an article is measured by an “early” count (of citations through October 1992), and a “late” count (of citations through July 2002). Using either measure of article importance, the evidence suggests that private funders are more successful than the government at identifying important research. Jel classification D 780 . H 110 .

German administrative science is composed of different disciplines which combine to form a multi- rather than an interdisciplinary science. Its roots can be traced back to the integrated policy-science ( Policey-Wissenschaft ) of the eighteenth century, which went through a process of differentiation during the nineteenth century. In German universities today, teaching and research is divided into different departments, a main problem being the disproportionate nature of this multidisciplinary structure. In German administrative science, a legalistic approach still predominates, although, in the 1960s and 1970s, political scientists played an important role in empirical research and theoretical discussions. Looking ahead, however, there is now an excellent chance that with the rise of the governance approach this asymmetric multidisciplinarity can be turned into a more balanced administrative science, even if it will remain a composite discipline.  相似文献

In this paper, we address the often contentious debate over state and local recycling policy by carefully estimating the social net benefit of curbside recycling. Benefits are estimated using household survey data from over 4,000 households across 40 western U.S. cities. We calibrate household willingnesstopay for hypothetical bias using an innovative experimental design that contrasts stated and revealed preferences. Cost estimates are compiled from previous studies by the U.S. Environmental Protection Agency and the Institute for Local Self Reliance, and from indepth interviews with recycling coordinators in our sampled cities. Across our sample of cities, we find that the estimated mean social net benefit of curbside recycling is almost exactly zero. On a citybycity basis, however, our social netbenefit analysis often makes clear predictions about whether a curbside recycling program is an efficient use of resources. Surprisingly, several curbside recycling programs in our sample appear to be inefficient. © 2006 by the Association for Public Policy Analysis and Management.  相似文献

Accidental deaths by firearm injury were studied over 11 years, 1972–1982, in Metro-Dade County. A total of 54 cases were studied. After noting the percentage of the cases that occurred by year, the age, race, sex, of the victim were tabulated. Type of weapon, body part involved, whether self-inflicted or not, blood alcohol of victim were also studied along with scene circumstances. A final admonition to the reader on how to handle such cases is discussed.  相似文献
