A final course, or project is a standard requirement in Master of Public Administration (MPA) programs. This requirement is intended to permit the student to demonstrate advanced ability in the discipline. This article examines one such course at Florida State University. The course included readings, exercises, oral presentations, and a written report. This author assesses the merits and drawbacks of the course as well as notes the unintended consequences that resulted. In concluding the article, the author makes several recommendations for future courses based on the experiences gained in the Florida state model. 相似文献

Abstract
The author presents a relatively formal theory of the rule of law which includes three basic components: conceptual, institutional and axiological. He then emphasizes the differences between a formal and a substantive theory of the rule of law and highlights the advantages and limits of the former. Finally, the author indicates the importance of this type of theory, namely the values it implies such as predictability, justified reliance, autonomous choice, minimization of disputes and legitimacy.** 相似文献

The manner in which agenda change occurs demonstrates how institutional arrangements influence agenda priorities in the Supreme Court and Courts of Appeals. A neo-institutional theoretic perspective is employed to examine the dynamics of agenda formation in these courts. The article finds that the Supreme Court's agenda choices influence the decisions of litigants, interest groups, and lawyers to appeal certain cases to the Courts of Appeals. While the Supreme Court's agenda primarily is influenced by internal factors, it is constrained by agenda changes in the appeals courts. Critically, it is shown that these federal appellate courts exist within an endogenous system with respect to agenda formation, as both courts respond to agenda changes made in the other over time. 相似文献

Abstract: Taxes on betting are a major source of revenue for Australian state governments. Specific taxes on the racing industry date from 1915. However, the revenue potential has only been tapped in all the states since the legalisation in the past 30 years of off-course betting through the state-run totalisator (TAB). The introduction of the TAB followed a long period when various states adopted different policies towards off-course betting, ranging from legalisation of bookmakers' betting shops to attempts at complete suppression. In tracing the history of these policies, the focus is on "implementation failure", or the many administrative pitfalls and obstacles that were experienced. These include insurmountable tax evasion by bookmakers, regulatory capture of betting boards by bookmakers and corruption of the law enforcement agencies. State governments also had to accommodate a range of conflicting interests, including the interests of the racing industry itself and the demands of the anti-gambling lobby. The TAB is shown to be a happy and convenient resolution of most, but not all, of these administrative and political dilemmas. 相似文献

A report of an international collaborative experiment to demonstrate the uniformity obtainable using DNA profiling techniques. 总被引:2,自引:0,他引:2

This paper describes a collaborative exercise intended to demonstrate whether uniformity of DNA profile results could be achieved between different European laboratories. It was shown that this goal can be obtained provided that a common protocol is followed (specifically the use of a common electrophoretic buffer as being the most important parameter). Generally, lower molecular weight loci (with lower molecular weight fragments) such as YNH24 perform better than higher molecular weight loci such as MS43a. The results of the exercise are discussed in relation to the objectives of the European DNA profiling group (EDNAP). 相似文献

In the forensic science laboratory, the recovery of spermatozoa from vaginal swabs, or vaginal cells from penile swabs, can help determine if sexual intercourse may have taken place. There are several methods used to recover spermatozoa and cells from the swabs before visualisation on a microscope slide and most of these methods use water. Phosphate buffered saline (PBS) is a non-toxic solution used in many biological laboratories. Unlike water, PBS prevents cells rupturing or shrivelling up due to osmosis. This study demonstrates that PBS can be used for the extraction of spermatozoa and cells from swabs and that PBS does not affect subsequent DNA profiling. 相似文献

This article examines the extent to which changes in distributional benefits influence congressional election outcomes. Although conventional wisdom holds that a direct link exists between distributional benefits and electoral outcomes (Mayhew 1974b), recent evidence suggests that this link only exists under certain circumstances (Stein and Bickers 1994). In this article, I use 1995 military base closures to test the nature of the relationship. Contrary to recent research on the politics of pork barreling, my findings indicate support for a direct relationship between major base realignments and closures and House electoral outcomes. Specifically, major realignments and closures significantly decreased first‐year Democrats' vote margins in the 1996 House elections. 相似文献
