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

This paper presents the results of an evaluation of an early intervention, risk-reduction strategy versus a standard intervention approach in the treatment of inner-city youth at high risk of adopting a deviant lifestyle. It examines baseline and 1-year follow-up information provided by 408 youth admitted to 2 community-based Baltimore City Youth Bureaus offering counseling services for neighborhood youth referred for delinquent and other problematic behavior. In the study, one of these bureaus served as the experimental intervention clinic and the other as the control, or standard intervention, clinic. Outcome measures involved substance abuse; sexual activity; contact with juvenile authorities; and delinquent activity, including violence-related activity. Regression analyses of outcome measures revealed significant differential results for delinquent activity, which favored the experimental intervention. Relationships between risk/protective factors and outcome are discussed.  相似文献

Privately sold bond insurance is the most common form of credit enhancement for municipal bonds. Research generally finds that bond insurance reduces interest costs for lower rated, long–term debt issues. Researchers have concluded that these results are consistent with presumed investor risk aversion, as well as more "rational" risk management behaviors, and with theories concerning the efficiency–enhancing properties of financial intermediation in imperfect markets. We propose a research agenda based both on traditional theories and on additional hypotheses that seek to account for the observed use of bond insurance where net savings would not normally be predicted.  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
