A consumer-demand or subjective-value approach to valuing government health activities is recommended. The human-capital valuations generally used in cost-benefit analysis are unrelated to peoples' preferences and, therefore, irrelevant to political decisions. A number of important policy conclusions emerge from applying the suggested principle that government activities be valued on the basis of what people would be willing to pay for them: Beyond programs to aid the poor, government health efforts should be restricted to overcoming deficiencies in the operations of the private marketplace; that is, to regulatory actions, control of infectious disease and environmental pollution, and aid to biomedical research. Free services provided to the poor should be justified by the willingness of the nonpoor to pay for them. Thus, the preferences of the nonpoor are important in designing optimal poverty programs. Under present circumstances, direct money transfers to the poor seem preferable to further increases in poverty medical programs. The value of existing programs could be increased by giving more weight to what the poor want instead of what medical experts say is most important for their health.The people who have assisted in the preparation of this paper are truly too numerous to mention in total. I am particularly indebted to Ed Park and Jim DeHaven of Rand for their helpful discussions, to Paul Feldman of the Institute for Defense Analysis for ideas, stimulation, and encouragement, and to Dick Zeckhauser of Harvard for his perceptive comments on an earlier draft. 相似文献

Rapid determination of ketamine in urine by liquid chromatography-tandem mass spectrometry for a high throughput laboratory 总被引:2,自引:0,他引:2
In recent years, the abuse of ketamine had gained popularity in rave parties in Hong Kong. The Urinalysis Unit of the Government Laboratory of Hong Kong faced a tremendous increase in workload for ketamine analysis. The number of tests performed rose from 10 in 1999 to 15,000 in 2002. As a fully validated immunoassay test for ketamine was not available in the market, most laboratories analyzed ketamine by chromatographic techniques after liquid-liquid extraction. However, these methods reported in the literature are not suitable for high throughput laboratories. Hence, a rapid screening/confirmation method for ketamine by liquid chromatography-tandem mass spectrometry (LC-MS-MS) with a detection limit of 5 ng/ml was developed. After automated solid-phase extraction (SPE), the urine extract was analyzed for ketamine by a 2.5-min chromatographic run, the estimated recovery was 89% and the precision was 11% R.S.D. at 20 ng/ml. With the aid of an in-house developed computer program, the results were presented in spreadsheet format for easy checking. The method has been applied to our laboratory for routine ketamine analysis and a maximum of 200 samples per day can be achieved. 相似文献

Gender Differences Among Adolescents in Family,and Peer Influences on Body Dissatisfaction,Weight Loss,and Binge Eating Behaviors 总被引:6,自引:0,他引:6
The present study examined perceived family and peer influences on body dissatisfaction, weight loss, and binge eating behaviors in adolescents. Three hundred and six girls aged 11 to 17 years (M = 13.66, SD = 1.12) and 297 boys aged 11 to 18 years (M = 13.89, SD = 1.13) completed a questionnaire that examined the direct influence and quality of family and peer relationships on body dissatisfaction and disordered eating. Direct influences of family and peers, rather than the quality of these relationships, predicted body dissatisfaction and disordered eating in adolescent boys and girls. Interesting differences were found between girls and boys in the nature of the influences and in the way they were expressed. In particular, parental and peer discussion and encouragement of weight loss predicted disordered eating behaviors in girls, while maternal and peer encouragement predicted binge eating and weight loss behaviors in boys. Fathers played a salient role in the expression of more severe forms of eating problems, while siblings played a small yet significant role in cognitive restraint among girls. The findings highlight gender differences in the importance of significant others in the expression of body dissatisfaction and disordered eating in adolescence. 相似文献

The identification of insects found on a dead body can lead to the estimation of the time of death (postmortem interval). We report an updated version of an established method based on sequence analysis of PCR products from a region of the cytochrome b oxidase subunit I mitochondrial gene of different members of the family Calliphoridae, by sequencing six European species: Lucilia sericata (Meigen), Lucilia caesar (Linné), Lucilia illustris (Meigen), Calliphora vicina (Robineau-Desvody), Calliphora vomitoria (Linné), Protophormia terraenovae (Robineau-Desvody) and one Guianese species: Cochliomyia macellaria (Fabricius). This technique provided clear results when applied to the larvae and we also report the identification of empty puparia. 相似文献

Sommaire: Depuis le milieu des années 70, au Québec, l'engorgement des services d'urgence est un problème qui refait surface de facon épisodique. En 1986, le gou-vernement québécois adopte un vaste plan visant à corriger la situation. En 1990, l'échec relatif de cette politique mène à I'adoption d'une nouvelle politique qui sera elle-même modifiée en 1993. Dans cet article, nous examinons les processus récur-rents d'émergence, de formulation et de mise en euvre de la politique québécoise de désengorgement des services d'urgence. Nous recourons, pour ce faire, à une version étendue du modèle proposé par Kingdon pour expliquer la mise à I'ordre du jour de certains problèmes publics par le gouvernement. Nous soutenons que le prolonge-ment donné au modèle de Kingdon permet de rendre compte des différentes phases de réalisation de la politique. Abstract: In the Province of Quebec, the overcrowding of hospital emergency wards has been a problem since the mid-seventies. In 1986, the Quebec government adopted a vast plan to correct the situation. The relative failure of the plan led to the adoption of a new policy in 1990, later modified in 1993. In this paper, we study the recurring emergence, formulation and implementation of Quebec policy towards emergency ward overcrowding. This study is based on an extended version of the model put forward by Kingdon to explain how some public problems appear on a government agenda while others are left aside. We contend that Kingdon's extended model is helpful to further our understanding of the policy process towards emergency wards in Quebec. 相似文献

This article examines productivity growth and effects of incentive payments on it in China's state‐owned enterprises. Data spanning the 1979–1993 period were taken from 20 large‐and medium‐scale state‐owned textile enterprises in Guangzhou. The empirical study finds that the sample enterprises experienced an average increase in total factor productivity growth by 1.8% annually. The analysis of the effects of incentive payments on productivity shows that total factor productivity growth is positively tied to increases in retained profits but it bears no significant relationship with increases in bonuses. Besides, the study suggests a positive time trend of total factor productivity growth by 0.8% per year. 相似文献

The author examines the sources and premises of the idea that free expression has value in part because of the function it performs in checking the abuse of official power (the "checking value") and explores how this checking value difyers from those values that have dominated First Amendment analysis since 1919. In addition, the author traces in some detail the uneven influence the checking value has had recently in three areas of First Amendment adjudication: civil actions f o r defamution; disputes arising from efforts by journalists to protect or establish relationships with news sources; and claims b y nonjournalists to a constitutional or statutory right to communicate directly to the public over major print or broadcast outlets. The author argues that the checking value must receive open, systematic consideration if it is to play a consistent part in adjudication and speculates on how such consideration of the checking value might help one think about a wide range of additional First Amendment questions. 相似文献
