Population drug use in Australia: a wastewater analysis 总被引:1,自引:0,他引:1

Accurate information on drug use in communities is essential if health, social and economic harms associated with illicit drug use are to be addressed efficiently. In most countries population drug use is estimated indirectly via surveys, medical presentations and police and custom seizures. All of these methods have at least some problems due to bias, small samples and/or long time delays between collecting the information and analysing the results. Recently the direct quantification of drug residues in wastewater has shown promise as a means of monitoring drug use in defined geographical areas. In this study we measured 3,4-methylenedioxymethamphetamine (MDMA), methamphetamine and benzoylecgonine in sewage inflows in metropolitan and regional areas of Australia and compared these data with published European data. Cocaine use was small compared to European cities (p<0.001) but was compensated for by much greater consumption of methamphetamine (p<0.001) and MDMA (p<0.05). MDMA was more popular in regional areas (p<0.05) whereas methamphetamine and cocaine were mainly consumed in the city (p<0.05). Greater than 5-fold increases in MDMA use were detected on weekends (p<0.001). This approach has the potential to improve our understanding of drug use in populations and should be further developed to improve prevention and treatment programs. 相似文献

This article traces the development of approaches to outsourcing by successive Australian governments from 1995. The analysis focuses on strategies initially adopted for the outsourcing of government information technology (IT) services and, subsequently, includes the market testing approach adopted for the outsourcing of both IT and corporate services. The framework for analysis has been based on theories of privatisation developed by Feigenbaum, Henig and Hamnett (1999). This framework offers insights into the goals and strategies employed by commonwealth government that underpin their approaches to sourcing of services for their public sector. The article concludes by discussing some of the unresolved issues associated with the failure of government to formally evaluate the impact of their outsourcing policies. 相似文献

The role of institutions as determinants ofrent seeking success is well established. In this paper, we focus on institutionsthat have received little attention in theliterature, namely electoral institutions. We examine three measures of electoralinstitutional structure that arehypothesized to be instrumental indetermining the level of rent seekingsuccess. These are the type of electoralsystem, pluralistic or proportional; methodof selection of the chief executive,presidential or parliamentary; and thenumber of electoral districts. An index ofeconomic freedom is used as the metric forrent seeking opportunities created bygovernments. Theoretical implications ofvariation in these electoral institutionsare developed. These implications areempirically tested employing data from 29countries classified as having emergingmarket economies. Countries with emergingeconomies are expected to exhibit moreinstitutional flexibility that moredeveloped countries whose property rightsare well established and defended. Theempirical results are controlled fordifferences in a number of demographic andhistorical factors. Plurality electoralsystems are more resistant to the politicaldemands of rent seeking than proportionalsystems. Fewer election districts seem toreduce rent seeking opportunities. However, conditional on the type ofelectoral system, presidential systems arefound to be no more resistant to rentseeking than parliamentary systems. Finally, we find strong control effects. Literacy increases a country's resistanceto rent seeking while military spending andyears of institutional entrenchment reduceit. 相似文献
