As growing numbers of local authorities in England are facing up to funding challenges, many of them are looking to commercialising services to increase revenue and to balance their budgets. This commentary paper outlines the characteristics of commercialisation and the drivers for it, reviews the commercial strategies being introduced by a number of local authorities, and offers some general reflections on commercialisation within local government. Although local authorities have created their own individual commercialisation strategies, a number of general themes can be identified within these strategies. These common themes include the drivers for commercialisation; the vision, aims, and objectives of commercialisation strategies; delivery plans and priorities; measurement; and risk management. In reflecting on local authority commercialisation strategies, the authors highlight the importance of developing both a communications plan and new skills and knowledge bases for employees, and they link their findings to the privatisation of public sector services and to neoliberal models of local service provision. 相似文献

In February 2009, the National Academy of Sciences published a report entitled "Strengthening Forensic Science in the United States: A Path Forward." The report notes research studies must be performed to "…understand the reliability and repeatability…" of comparison methods commonly used in forensic science. Numerical classification methods have the ability to assign objective quantitative measures to these words. In this study, reproducible sets of ideal striation patterns were made with nine slotted screwdrivers, encoded into high-dimensional feature vectors, and subjected to multiple statistical pattern recognition methods. The specific methods employed were chosen because of their long peer-reviewed track records, widespread successful use for both industry and academic applications, rely on few assumptions on the data's underlying distribution, can be accompanied by standard confidence levels, and are falsifiable. For PLS-DA, correct classification rates of 97% or higher were achieved by retaining only eight dimensions (8D) of data. PCA-SVM required even fewer dimensions, 4D, for the same level of performance. Finally, for the first time in forensic science, it is shown how to use conformal prediction theory to compute identifications of striation patterns at a given level of confidence. 相似文献

The concentrations of zolpidem and zopiclone were determined in peripheral blood samples in two forensic materials collected over a 10-year period (2001-2010). The z-hypnotics were determined in venous blood from living subjects (impaired drivers) and in femoral blood from deceased persons (forensic autopsies), with the latter classified as intoxication or other causes of death. The z-hypnotics were determined in blood by capillary column gas chromatography (GC) with a nitrogen-phosphorous (N-P) detector after solvent extraction with n-butyl acetate. The analytical limit of quantitation (LOQ) was 0.02mg/L for zopiclone and 0.05mg/L for zolpidem and these have remained unchanged throughout the study. When death was attributed to drug intoxication (N=918), the median concentration of zopiclone in blood was 0.20mg/L compared with 0.06mg/L for other causes of death (N=1215) and 0.07mg/L in traffic offenders (N=691) (p<0.001). Likewise, a higher median concentration (0.30mg/L) was found in intoxication deaths involving zolpidem (N=357) compared with 0.13mg/L for other causes of death (N=397) or 0.19mg/L in impaired drivers (N=837) (p<0.001). Median concentration in blood of both z-hypnotics were appreciably higher in intoxication deaths when no other substances were identified; 0 70mg/L (N=12) for zopiclone and 1.35mg/L (N=12) for zolpidem. The median concentrations of z-hypnotics in blood decreased as the number of co-ingested substances increased for intoxication deaths but not other causes of death. The most prevalent co-ingested substances were ethanol in autopsy cases and diazepam in the motorists. This large compilation of forensic cases should prove useful when toxicologists are required to interpret concentrations of z-hypnotics in blood samples in relation to cause of death. 相似文献

Empirical studies of violence and mental illness have used many different methods. Current state-of-the-art methods gather
information from both subject and collateral interviews as well as official records. Typically these sources are treated as
additive. Any report of a violent incident from any source is treated as true and all reported incidents are added to generate
estimates of frequency. This paper presents a new statistical technique that uses the level of agreement between the sources
of data to adjust those estimates. The evidence suggests that, although the additive technique for using multiple sources
correctly estimates how many people are involved, it substantially underestimates the number of incidents. The new technique
substantially reduces both false negatives and false positives. 相似文献

Environmental regulatory design addresses scientific uncertaintythrough a range of regulatory design tools. The seven approachesidentified and considered in this article are termed (1) theacknowledgement of scientific uncertainty (2) the burden shiftingapproach (3) the sound science approach (4) theconsequences approach (5) the consensus approach (6) the estimationapproach and (7) the adaptive management approach. Analysisof some common environmental legislative frameworks suggeststhat, rather than occurring in isolation, these seven approachesare frequently incorporated into legislative regimes in a multitudeof combinations. The article also highlights the implicationsof expressly embedding a precautionary approach within pre-existingenvironmental regulatory frameworks, such as has occurred withinAustralian environmental regimes. Finally, the article exploresthe advantages and disadvantages of each approach and the variouscircumstances that favour the adoption of a particular regulatoryapproach to scientific uncertainty. In doing so, it suggestsan agenda for future empirical research on approaches to regulatorydesign for scientific uncertainty. 相似文献
