Abstract: This paper examines policy arguments for further restricting supply to the Australian General Practice profession by immigration and medical school policies. It uses economic analysis to assess the costs and benefits of supply restrictions. The effects of Medicare and GP income-targeting on policy design are analysed. Restrictions are shown to impose net costs on the community as a whole and on government. Even with Medicare subsidies, the inefficiency costs of the current health system are minimised with liberal policies for accepting foreign- trained GPs.  相似文献

There is a growing awareness of the complex and largely negative attitudes many girls in the UK hold towards physical activity in general and Physical Education (PE) in particular. This research in the UK involves a qualitative study of six Year 9 girls' experiences and motivations in PE.Reflexive interpretation and biographical analysis of in-depth interviews are utilized to explore the themes of the relationship between “sportiness” and heterosexual desirability; and the polarized images of “tomboy” and “girlie.” Work by Connell [Connell, R.W. (1987). Gender and power. Cambridge: Polity Press.] on the gender order, and theories arising from the cultural analysis tradition on teenage girls' subcultures and identity formation are drawn on in order to make sense of the girls' narratives.The findings of this research reveal that images of teenage girls and young women being physically active are non-congruous with the traditional ideologies of acceptable femininity. This paper describes how these girls negotiate the contradictions and the tensions caused by the “femininity deficit” incurred in PE by creating “double identities” and living “split lives.”  相似文献

One aspect of the multifaceted controversy on value change in advanced industrial societies concerns the measurement of values. Analyses of 1976–86 Euro-Barometer data have indicated that responses to the four-item “materialist-postmaterialist” values index are very sensitive to current economic conditions, especially inflation and unemployment rates and, hence, much of the recorded increase in postmaterialism in eight Western European countries since the mid-1970s is artifactual. Although it has been claimed these findings disappear if more recent data are considered, time series analyses reveal that responses to the values measure are strongly affected by prevailing economic conditions throughout the entire 1976–92 period. These aggregate-level findings are buttressed by individual-level analyses of 1989 Euro-Barometer data.  相似文献

Eighteen external quality assessment (proficiency testing) samples were prepared from client specimens collected with the Intercept oral fluid collection device and by spiking drug-free oral fluid. Samples were circulated in pairs at quarterly intervals to 13 UK and USA based laboratories for analysis by a panel of OraSure micro-plate Intercept enzyme immunoassay kits and hyphenated mass spectrophotometric techniques. During the survey, there was a single case of non-specificity in a false report for methadone. The major errors were of lack of sensitivity relative to the concentration thresholds specified for the immunoassays. The sensitivity for overall "present"/"not found" reports calculated as true positives/(true positives+false negatives) were for the amphetamine specific assay 50%, methyl-amphetamines 93%, barbiturates 64%, cannabinoids 73%, cocaine and metabolites 100%, benzodiazepines 69%, methadone 95%, opiates 79% (opiates excluding oxycodone 93%), phencyclidine 93% and human gamma-globulin 97%. A small number of the sensitivity errors were attributable to errors in chromatographic confirmation techniques.  相似文献
