The display and regulation of child anger in family interaction was coded in a sample of 240 boys and girls at child age 6, and coded using the Specific Affect Coding System. Child antisocial behavior was longitudinally assessed, beginning in kindergarten. Pooled‐ and family‐level analyses were used to assess hazard rates for child anger. Parents’ ability to modulate their own emotions and negative behavior, and children's ability to down‐regulate anger were associated with increased latency for child anger. Hazard for child anger increased as parents’ insensitive and negative responses toward the child cumulated during family interaction. Macro‐level, non‐hazard analyses indicated that chronic levels of child antisocial behavior were associated with the frequency of parental negative behavior, but not with the frequency of child anger. Micro‐level hazard analyses indicated that children's ability to regulate anger was related to chronic levels of child covert but not overt antisocial behavior.  相似文献

Previous research has identified methodological problems in the design and conduct of randomized trials that could, if left unaddressed, lead to biased results. In this report we discuss one such problem, inadequate control intervention, and argue that it can be by far the most important design characteristic of randomized trials in overestimating the effect of new treatments. Current guidelines for the design and reporting of randomized trials, such as the Consolidated Standards of Reporting Trials (CONSORT) statement, do not address the choice of the comparator intervention. We argue that an adequate control intervention can be selected if people designing a trial explicitly take into consideration the ethical principle of equipoise, also known as "the uncertainty principle."  相似文献

Two approaches have been used for designing spatial surveys to detect a target. The classical approach controls the probability of missing a target that exists; a Bayesian approach controls the probability that a target exists given that none was seen. In both cases, information about the likely size of the target can reduce sampling requirements. In this paper, previous results are summarized and then used to assess the risk that Roman remains could be present at sites scheduled for development in Greater London.  相似文献

Encouraging students to self-regulate their learning in relationto ‘race’ issues would appear to be pertinent toa profession that promotes life-long learning and holds valuesof self-determination and respect for the individual at itscore. This study examined the written feedback students receivedin relation to key assignments in years two and three of a socialwork degree programme. The findings suggest that feedback isseldom used in a way that might enhance students understandingof ‘race’ issues. If students are developing anunderstanding of racism and anti-racist practice, then it doesnot appear to be a result of the written feedback from tutorsand practice teachers. Given the importance of feedback in helpingstudents to self-regulate and develop their learning, it maybe useful to adopt a more principled approach.  相似文献

With large numbers of GPs due to retire by 2007, the recruitment and retention crisis in UK general practice is likely to get worse before it gets better. Urgent measures are now required. Policies such as offering doctors financial incentives to enter general practice or delay retirement, while increasing the number of medical school places, may, for a variety of reasons, be likely to enjoy only limited success. In this article, a more radical solution is proposed: the creation of an intermediate medical practitioner role, along the lines of the physician assistant in the USA. The establishment of such a role may go some way to resolving the workforce crisis that currently besets general practice and ensure that medical needs, especially in deprived areas, are adequately met. A number of specific occupational groups who may find the PA role attractive are identified. It is suggested that refugee doctors, unable to practise in the UK, may find PA training particularly attractive, especially if it could serve as a stepping-stone to GMC registration.  相似文献

I evaluate the effects of prevailing wage laws using a unique data set that shows the wages paid to workers on prevailing wage projects and the wages paid to the same workers during the same time period for work on projects not covered by prevailing wage regulations. The wage comparison shows that workers are generally paid more for work on prevailing wage projects than they are for work on nonprevailing wage projects. Thus, prevailing wage laws likely do increase the cost of public construction. In addition, to the extent that the quality of construction is improved, prevailing wage laws appear to be an inefficient mechanism by which to achieve additional quality, as the regulations often result in workers being paid more than they earn in the private market. This research was done originally for the Program Review and Investigations Committee of the Kentucky State Legislature. I thank the staff of the Program Review and Investigations Committee and the Legisla-tive Research Commission for assistance with data collection and Mark Berger for helpful comments. Due to confidentiality requirements, the data cannot be made available.  相似文献
