Abstract.  The four theses of this paper are: (1) that an appropriate organizational form is used to design, define, and organize a functional unit of a legal system, (2) that the functional units of a legal system, contrary to the emphasis in Hart and Kelsen, consist of far more than rules, and include institutions, interpretive and other methodologies, sanctions and remedies, and more, (3) that frontal and systematic study of the forms of these units is a major avenue for advancing understanding of them as duly organized wholes, and, (4) that such study reveals that much credit is due these forms, along with complementary material or other components of the units, for values realized through law.  相似文献

The paper examines the airline industry ten years after the Airline Deregulation Act of 1978. A brief review of the historical background of regulation and the changes leading to the Airline Deregulation Act is presented. A number of studies are cited that conclude that airline perfor- mance has improved since the Civil Aeronautics Board days. The author agrees with these conclusions but goes on to suggest that it is time to begin comparing the airline industry today with the standards of performance associated with perfect competition instead of the previous regulatory period. A standard of competitive performance is suggested. The traditional p=mc=ac performance is complicated because mc and ac decline for any airline flight until the plane is full or has a 100% load factor. The author suggests p=acat load factors are not yet reaching loo%, it is suggested that some policy modifications might help improve performance further. An- titrust is examined and some other institutional policy changes are sug- gested.  相似文献

Congress and the Drug Enforcement Administration have assigned certain psychoactive substances to one of five schedules, based on assumed or demonstrated abuse potential. Although formidable difficulties exist in assessing the hazards of drug use, some of these assignments do not appear consistent with empirical estimates. This mismatch of assignment and abuse potential -possibly due to "radical" political ideology - obscures significant differences in drug effects, and therefore stifles meaningful public participation in evaluating the benefits, risks, and proper use (if any) of available psychoactive substances.  相似文献

Although past research has developed scales for the incidence, prevalence, and fear of student-on-student victimization (SSV), little is known about the scaling of perceived risk (i.e., the cognitive appraisal of the chances of experiencing SSV). Hence, this study examined self-report survey data for the perceived risk of SSV as measured in the Adolescent Index for School Safety (AISS). Children in grades 7 through 10 (n=337) in a single Florida public school completed the AISS. Factor analyses using Maximum Likelihood Estimation with Oblimin Rotation identified nine unique factors for perceived risk. Reliability analyses found standardized Cronbach Alphas that ranged from .64 to .91, and seven out of the nine identified scales were above .80, which suggested good to excellent internal consistency. Future research should examine the content validity, construct validity, and predictive validity for the AISS and other self-report surveys of SSV dynamics. This publication was made possible by a grant [#97-MU-FX-KO12 (S-l)] from the Office of Juvenile Justice and Delinquency Prevention (O.J.J.D.P.), United States Department of Justice (U.S.D.O.J.). This grant is administered through the Hamilton Fish National Institute on School and Community Violence at George Washington University. This specific study was developed and implemented by staff at: 1) East Carolina University’s Department of Criminal Justice; and 2) Florida State University’s Center for Educational Research and Policy Studies. All points of view and opinions in this paper are those of the authors and do not necessarily represent the official position or policies of East Carolina University, Florida State University, the Hamilton Fish National Institute on School and Community Violence, the O.J.J.D.P., or the U.S.D.OJ. The authors would also like to thank Dr. Bill Doerner and Jennifer Jolley for their support, editorial feedback, and insightful comments regarding earlier drafts of this paper.  相似文献
