This paper addresses the changing role of the Portuguese state, the present priority assigned to the process of reform and the new challenges to be overcome by public administration. Such processes are demanding a new agenda for education and research in public administration sciences, shifting from the public law paradigm to an interdisciplinary problem‐solving approach and giving special attention to 10 key areas of study, which we describe in the final section of the paper. It should be noted here that the opinions expressed in this paper do not necessarily reflect the position of their institutions. 相似文献

Modern antitrust policy has a love hate relationshipwith non-standard contracts that can overcome market failure.On the one hand, courts have abandoned various per se rulesthat once condemned such agreements outright, concluding thatmany non-standard contracts may produce benefits that are cognizableunder the antitrust laws.1 The prospect of such benefits, itis said, compels courts to analyze these agreements under theRule of Reason, under which the tribunal determines whethera given restraint enhances or destroys competition.2 At thesame time, courts, scholars, and the enforcement agencies haveembraced methods of rule of reason analysis that are undulyhostile to such agreements.3 In particular, courts and othersare too quick to view such agreements and the market outcomesthey produce as manifestations of market power. This articleseeks to explain why these agreements are still the object ofundue hostility. 相似文献

Is medical care different? Old questions, new answers 总被引:3,自引:0,他引:3
M V Pauly 《Journal of health politics, policy and law》1988,13(2):227-237
This paper examines whether changes in medical markets may be making them more like other markets. The emergence of HMOs and other managed care systems appears to have increased the consumer's potential ability to make better comparative judgments about the price and quality of medical care, and also seems to have made medical care more like other goods. However, the evidence that medical care is a "reputation good" suggests that it is, in this respect, different from other goods. Finally, the social concerns about medical care use necessarily make medical care different. 相似文献

Effects of positional restraint on oxygen saturation and heart rate following exercise 总被引:1,自引:0,他引:1
D T Reay J D Howard C L Fligner R J Ward 《The American journal of forensic medicine and pathology》1988,9(1):16-18
This report assesses the effects on peripheral oxygen saturation and heart rate that positional restraint induces when a person is prone, handcuffed, and "hog-tied." Peripheral oxygen saturation and heart rate were monitored at rest, during exercise, and during recovery from exercise for 10 adult subjects. The effects of positional restraint produced a mean recovery time that was significantly prolonged. Consequently, the physiological effects produced by positional restraint should be recognized in deaths where such measures are used. 相似文献
