This article explores theoretical and empirical issues in the application of clinical neuropsychological evidence to forensic issues in the criminal law. The nature of forensic neuropsychological evaluations is discussed with reference to issues of competency to stand trial, criminal responsibility, and other competencies in the criminal process. Examples of specific disorders relevant to criminal law standards are presented, together with data estimating the prevalence of brain dysfunction in criminal and forensic populations. Research is also reviewed on the role of neuropsychological brain dysfunction in the etiology of violence and criminally relevant behavior. Finally, empirical and ethical issues concerning the applicability and admissibility of forensic neuropsychological data in the criminal context are discussed. 相似文献

Survival of the public service ethos in Britain has been called into question following introduction of the 'new public management' and marketizing reforms in much of the public sector. This article examines how these developments have occurred in the NHS, using survey data to analyse NHS board members' substantive ethical values. Unexpectedly the results suggest that NHS board members with a predominantly NHS background appear less ethically conservative, more flexible and less risk–averse than those recruited from non–NHS backgrounds; and that as yet the NHS management 'culture' is not very homogenous in respect of 'business ethics'. The NHS reforms also appear to accentuate the tensions between transparent public accountability in NHS management and incentives not to publicize certain types of information. Recent codification of NHS 'business ethics' can be understood as an attempt to buttress the public service ethos against the increased moral strains of a quasi–market. 相似文献

Using merged administrative data from welfare reform evaluations in three states, we estimate the effects of child care subsidy use on the length of time it takes for a welfare applicant to move into substantial employment. Findings show that the use of a child care subsidy during an unemployed or marginally employed spell of welfare receipt is associated with between a 0.6 and 1.7 quarter (or 11% to 34%) reduction in the time to substantial employment in two of the three state samples. The positive influence of subsidy use on transitions to substantial employment is strongest for those welfare applicants with the lowest earnings who are mixing welfare and work prior to subsidy receipt. 相似文献
