In March 2012 the Ministry of Justice published two consultations: Punishment and reform: effective probation services and Punishment and reform: effective community sentences. Taken together, the two documents have the potential to impose wholesale reform on the work of Probation Trusts in England and Wales, primarily through the privatisation of considerable sections of Trusts’ work. 相似文献

The nature and role of political parties is changing in contemporary Britain. There has been a decline of both party identification among voters and of ideological commitment linked to class, coupled with the growth of alternative political agenda. But government in Britain is dependent on success in an electoral system which relies heavily not only on a party's general level of support but also on the geography of that support. Voters have to be mobilized locally, by party organizations run by activists. The Conservative Party appears to have increasing problems doing this. 相似文献

Ensuring the safety of staff and patients has become a major problem for hospitals in China. This article examines whether one of the reasons for this violence may be the emerging injustice and inequality that have manifested in the Chinese health care system as a result of privatisation reforms since the early 1980s. It considers approaches to these issues that may assist the Chinese Government, and other nations contemplating similar policy changes, to create efficient but equity-based health care systems that minimise collateral trauma to patients and their families. 相似文献

Identification of 6-acetylmorphine, a specific metabolite of heroin, is considered to be definitive evidence of heroin use. Although 6-acetylmorphine has been identified in oral fluid following controlled heroin administration, no prevalence data is available for oral fluid specimens collected in the workplace. We evaluated the prevalence of positive test results for 6-acetylmorphine in 77,218 oral fluid specimens collected over a 10-month period (January-October 2001) from private workplace testing programs. Specimens were analyzed by Intercept immunoassay (cutoff concentration=30 ng/ml) and confirmed by GC-MS-MS (cutoff concentrations=30 ng/ml for morphine and codeine, and 3 ng/ml for 6-acetylmorphine). Only morphine-positive oral fluid specimens were tested by GC-MS-MS for 6-acetylmorphine. A total of 48 confirmed positive morphine results were identified. An additional 107 specimens were confirmed for codeine only. Of the 48 morphine-positive specimens, 32 (66.7%) specimens were positive for 6-acetylmorphine. Mean concentrations (+/-S.E.M.) of morphine, 6-acetylmorphine and codeine in the 32 specimens were 755+/-201, 416+/-168 and 196+/-36 ng/ml, respectively. Concentrations of 6-acetylmorphine in oral fluid ranged from 3 to 4095 ng/ml. The mean ratio (+/-S.E.M.) of 6-acetylmorphine/morphine was 0.33+/-0.06. It is suggested that, based on controlled dose studies of heroin administration, ratios >1 of 6-acetylmorphine/morphine in oral fluid are consistent with heroin use within the last hour before specimen collection. The confirmation of 6-acetylmorphine in 66.7% of morphine-positive oral fluid specimens indicates that oral fluid testing for opioids may offer advantages over urine in workplace drug testing programs and in testing drugged drivers for recent heroin use. 相似文献

The concept of party identification is widely used in British electoral studies, but its value as a measure of underlying links between voters and parties, irrespective of short-term fluctuations in partisan popularity, has come under increased scrutiny recently. Data from the first four waves of a longitudinal study provide evidence of substantial variability in the strength of voters' identification with the three main British political parties, suggesting the need for research into the causes of, and meanings associated with, such fluctuations. 相似文献
