The population of children around the world who require alternative care outside of the natural family is staggeringly large. This presents fundamental dilemmas and challenges for every nation. This article notes how the United Kingdom's (UK's) response has evolved from that of a non-interventionist state to one that claims an interest in “Every Child”. Attention is drawn to the way in which the State's “Third Way: What matters is what works” ideology has led to radical reform of public sector services and the widespread sub-contracting of alternative care for children to the independent sector.

The article presents rare data on the relative performance of children in public sector as opposed to costly independent foster care. Contrary to expectations the data reveal minimal differences between the two groups. The data offer no justification, on the grounds of efficacy, for the use of independent sector provision as opposed to public sector provision.  相似文献

Observers argue that the business of news is responsible for worsening the coverage of terrorism, but exactly how economic considerations influence coverage is controversial. Based on an analysis of over 1600 articles from The Washington Post and USA Today, we find that concerns about the effects of economic pressures on terrorism reporting are exaggerated. The business climate affects coverage, but the long-term impact of market pressures on coverage is modest. Articles about terrorist violence are increasingly prominent, but coverage of counterterrorism remains robust. Efforts to inoculate the press against the worst excesses of the market are unnecessary.  相似文献

The move to ordain women as priests and bishops in the Church of England has taken nearly 40?years of campaigning in General Synod and almost 100 years of discussion and debate more widely in the Church. Christina Rees, a member of the Church of England's ruling body, the General Synod, considers why there has been such a long struggle, especially after agreeing that women can be ordained as priests, and therefore are suitable for Holy Orders. Over the past 25?years she has uncovered disturbing evidence that the insidious ideology of patriarchy has distorted theology in ways that has contributed to entrenched discrimination against women in the Church.  相似文献

The in vitro stability of cocaine in horse blood, sheep vitreous humour (VH) and homogenised deer muscle is described. The stability of cocaine in horse blood was of interest because many toxicology laboratories utilise horse blood for the preparation of calibration and check standards and the latter are typically stored during routine use. The storage stability of cocaine in human VH and muscle has not been previously reported. In the absence of blank human VH and muscle, cocaine stability under varying conditions was demonstrated in animal tissues. Blood and VH were stored with and without addition of NaF at room temperature (RT), 4°C and -18°C for 84 days. Muscle homogenates were prepared in water, water/2% NaF, and phosphate buffer (pH 6.0)/2% NaF, and stored for 31 days at RT, 4°C and -18°C. Cocaine stability in human muscle obtained from cocaine positive forensic cases was assessed following storage at -18°C for 13 months. Cocaine and benzoylecgonine (BZE) were extracted using SPE and quantified by GC-MS/MS. Cocaine was stable for 7 days in refrigerated (4°C) horse blood fortified with 1 and 2% NaF. In the absence of NaF, cocaine was not detectable by day 7 in blood stored at RT and 4°C and had declined by 81% following storage at -18°C. At 4°C the rate of cocaine degradation in blood preserved with 2% NaF was significantly slower than with 1% NaF. The stability of cocaine in horse blood appeared to be less than that reported for human blood, probably attributable to the presence of carboxylesterase in horse plasma. Cocaine stored in VH at -18°C was essentially stable for the study period whereas at 4°C concentrations decreased by >50% in preserved and unpreserved VH stored for longer than 14 days. Fluoride did not significantly affect cocaine stability in VH. The stability of cocaine in muscle tissue homogenates significantly exceeded that in blood and VH at every temperature. In preserved and unpreserved samples stored at 4°C and below, cocaine loss did not exceed 2%. The increased stability of cocaine in muscle was attributed to the low initial pH of post-mortem muscle. In tissue from one human case stored for 13 months at -18°C the muscle cocaine concentration declined by only 15% (range: 5-22%). These findings promote the use of human muscle as a toxicological specimen in which cocaine may be detected for longer compared with blood or VH.  相似文献

This article investigates the determinants of criminal activityamong juveniles in the United States. It uses a survey of U.S.high school students conducted in 1995, which provides detailedinformation on offenses; personal, family, and neighborhoodcharacteristics; as well as deterrence measures. The determinantsof selling drugs and committing assault, robbery, burglary,and theft are analyzed separately for males and females. Theresults provide some evidence that juveniles respond to incentivesand sanctions. Employment opportunities and policies designedto increase the probability of arrest may be effective toolsfor reducing juvenile crime.  相似文献
