Since the anthrax attacks of 2001 the need for methods to trace the origins of microbial agents has become urgent. The stable isotope ratios of bacteria record information from both the nutrients and the water used to make their culture media and could potentially be used to provide information about their growth environment. We present a survey of carbon (C), nitrogen (N), and hydrogen (H) stable isotope ratios in 516 samples of bacteriological culture media. The observed variation was consistent with expected isotopic variation in the plant and animal products upon which the media are based. The variation is sufficient to translate into substantial isotope variation in cultures grown on different batches of media, and thus to allow investigators to determine whether seized media could have been used to produce seized bioweapons agents.  相似文献

This study presents interview and statistical data from a telephone and fax survey of state agency officials and statistical data from the Centers for Medicare & Medicaid Services' Online Survey Certification and Reporting (OSCAR) system. State survey activities for nursing facilities were reviewed and the number and types of intermediate sanctions issued by states in 1999 were reported, along with barriers to the use of such sanctions. Using five selected enforcement measures to create a summary score, states were classified by quartiles based on the stringency of their nursing facility enforcement activities. Controlling for the number of complaints as a proxy for quality, the predictors of a summary of state enforcement actions were: percentage of population at age eighty-five and above. Democratic governors, higher percentages of chain facilities, and lower facility occupancy rates. Regional differences in enforcement patterns also were shown. Many federal policies and resource constraints were identitied as barriers to effective regulation. The findings identified nursing facility survey and enforcement issues that need to be addressed by policy makers.  相似文献

Previously developed histological age-estimating methods have been based on samples lacking interpopulation variability. A comparison of age-associated rib histomorphometrics between an European-American sample and an African-American sample indicates that ethnicity can have a significant effect on osteon population density (OPD), osteon cross-sectional area (On.Ar), and relative cortical area (Ct.Ar/Tt.Ar). Based upon these findings, new histological age-predicting formulae are presented that are recommended when estimating age for African-American or European-American skeletal remains. A general formula that is applicable to remains of unknown ethnicity is also provided.  相似文献

Performance information is crucial to effective management. Computer-based information systems (CBIS) now play a significant role in the effective delivery of information to senior managers. Executive information systems (EIS) are emerging as popular tools to assist organisations in their strategic decision-making processes. This trend has spread from the private to the public sector, and is now evident in Australian government organizations
This article draws on the findings of a survey into the uses and benefits of CBIS and EIS, from a sample of Australian local government organisations. The study shows that lessons from the private sector are being heeded by system developers in public organisations, leading to successful EIS projects, or at least improved CBIS. The study indicates that EIS, which were originally developed for profit-oriented private companies, are now seen as appropriate for many public sector organisations, providing effective delivery of information to senior managers. Survey results indicate that improved information systems give executives a more accurate picture of their organisation's performance and so provide support for improved strategic decision-making. In addition, EIS are seen by respondents as offering significant benefits not only to managers but also to the rest of the organization.  相似文献

Outsourcing of IT services is being undertaken at a rapid rate within the public sector in Australia. This paper investigates the adoption of this practice by a sample of state government enterprises and departments from South Australia, Victoria and New South Wales which have tendered long-term IT outsourcing contracts.
The motivation, decision-making process and extent of outsourcing are examined in further detail. In addition, the tendering process, contract and risk management are investigated to determine whether consideration has been given to the full economic costs involved in entering into longer term contracts.  相似文献

Governments, as well as the community at large, need disinterested analysis and advice. It is important that governments are advised on the options for and against intervention in what some perceive as wrongs, and the potential and likely costs as well as the benefits to the whole community of such interventions. When the Royal Commission on Australian Government Administration (RCAGA) was set up, most of this advice came from 'official sources': principally the Commonwealth Public Service, supplemented by official bodies such as the Tariff Board and the Bureau of Agricultural Economics. RCAGA was concerned about the narrowness of Australian policy discourse (especially in relation to economic policy), and explored several avenues for widening it. Ironically, these possibilities did not include what has turned out to be a very significant alternative to official sources: the use of outside consultants. This paper reviews the growing use of consultants in government, starting from the concerns of RCAGA, and exploring the institutionalisation of 'outside' advice, and the impact of this on the capacity of the public service to advise.  相似文献
