This article analyzes the constitutional role of the High Courtof Australia during its first hundred years and the effect ofthat role on the Australian federation. The High Court has acceptedas axiomatic that part of its function is the judicial reviewof legislation of both the federal and state legislatures. Itsapproach is relatively modest and "textualist." That approachhas been affected by historical changes, including Australia'sindependence from Great Britain. The decisions of the High Courthave provided a framework for the development of the Australianfederation over the last century in increasing the relativeimportance of the federal government at the cost of the stategovernments. However, those decisions are probably best viewedas reflecting, rather than creating, the changes and developmentsin the federation. 相似文献

There is a great deal of variation in the methods and wording used by medical examiners in the medicolegal investigation and certification of infant deaths. This paper was created by the NAME Ad Hoc Committee on Sudden Unexplained Infant Death to address several specific issues, namely: * To establish a functional approach to the investigation of sudden unexplained infant deaths; * To outline a "bare minimum" set of recommendations to define the scope of investigation required; * To recommend methods and wording to be used when certifying infant deaths; * To develop a list of potential stressors or possible external causes of death that should be identified and reported on the death certificate and/or within a medical examiner/coroner office database. This paper was electronically posted for NAME member review and comment for a period of 30 days. The paper was further revised based on member comments and then submitted to the NAME board of directors in the fall of 2005 prior to the annual meeting. This text of this paper was officially approved and endorsed by the NAME board of directors on October 14, 2005, at the annual meeting in Los Angeles, CA. 相似文献

It is a requirement that forensic DNA profiling evidence be accompanied by an estimation of its weight, in order that the court can assign an appropriate probative value to the evidence during legal proceedings. There are various models by which this estimation can be made, but each relies on approximations of the allele frequencies in the relevant population. It is also important to assess relevant population genetic features of the available data. This report provides allele frequencies and estimates of common population genetic parameters for the major sub-populations of the Northern Territory of Australia genotyped at 15 autosomal short tandem repeat (STR) loci. 相似文献

This article investigates the implementation of key performance indicators (KPIs) in Western Australia's public mental health system. A nationally agreed performance measurement framework forms part of the much needed reform now taking place within Australia. However, progress in the effective monitoring and reporting of KPIs is slow in most states, including Western Australia. The authors report on the results of a selective case study involving semi‐structured interviews with mental health administrators and offer a more nuanced insight into the intricacies and difficulties involved in performance measurement reform. The principal finding is that effective performance measurement and reporting can be internally problematic, particularly within a fragmented and networked system. This tends to give rise to a conformance‐only approach to performance measurement. 相似文献

In a recent incarnation of the public–private partnership, state or city governments agree to lease revenue‐producing assets to a private operator for a lengthy period, up to 99 years. The government receives an up‐front payment, allowing it to collect many years of future revenue at once. This article evaluates the distributional consequences across time of one asset lease, the Indiana Toll Road. The analysis finds that the majority of benefits, in the form of road construction, are enjoyed in the early part of the lease, while the bulk of the costs fall late in the lease, raising important questions about intergenerational fairness. 相似文献

Despite limited government control over the pre-1914 economy, opposition politicians were enthusiastic in blaming bad economic news on the incumbent. In a study of 458 by-elections between 1857 and 1914, we find that voters typically gave new governments a 'honeymoon' but thereafter held them responsible for high unemployment and high prices. Each 1% rise in the price level, on average, brought about a 0.21% swing against the government of the day, while each one-point rise in the percentage unemployed had double this effect. However, when we split the electorate into borough and county constituencies, economic voting appears to be confined to the former. 相似文献

How can we determine which arguments in a referendum are most persuasive? We show that the Bradley–Terry model has several features that make it well-suited to this task, and thus preferable to other, more conventional approaches. Using a survey experiment conducted during an electoral reform referendum in Ontario, Canada in October 2007, we demonstrate how unstructured and structured Bradley–Terry models can be straightforwardly fitted and interpreted. In doing so, we gain insight into the factors which determine support for electoral reform. We identify a status quo bias and find that power varies with mention of fairness, local control over candidate selection, and the role of political parties. We conclude by discussing the limits, extensions and further applications of such models in electoral studies and political science more broadly. 相似文献

Quartz sand surface texture analysis has been automated for the first time for forensic application. The derived Basic Image Features (BIFs) provide computer-generated texture recognition from preexisting data sets. The technique was applied to two distinct classification problems; first, the ability of the system to discriminate between (quartz) sand grains with upturned plate features (indicative of eolian, global sand sea environments) and grains that do not exhibit these features. A success rate of grain classification of 98.8% was achieved. Second, to test the ability of the computer recognition system to identify specific energy levels of formation of the upturned plate surface texture features. Such recognition ability has to date been beyond manual geological interpretation. The discrimination performance was enhanced to an exact classification success rate of 81%. The enhanced potential for routine forensic investigation of the provenance of common quartz sand is indicated. 相似文献
