Although nuclear DNA-profiling of human hairs is a well-known technique in forensic investigations, its success rate is quite low. Because the extracted nuclear DNA (nuDNA) is scarce and often degraded, a simple and effective method was developed to estimate the number of cell nuclei in telogen roots. DAPI, a fluorescent, non-destructive DNA-stain, allows visualizing nuclear DNA and does not interfere with subsequent PCR analyses. After staining 3242 roots from 27 volunteers and subsequent STR-profiling of a selection of roots, we show that the amount of analysable nuDNA can be predicted. This screening method allows the genetic laboratory to analyse only the most promising hair roots. 相似文献

The number of older offenders is rapidly increasing in the United Kingdom and some older adults with mental health issues are referred to secure care services. It is therefore important to understand their unique characteristics in order to develop services based on their individual needs rather than chronological age. This study explored wellbeing and security needs of younger and older patients admitted to a secure psychiatric hospital. HoNOS-secure assessment at admission and discharge was extracted and used to build an anonymous data-set. Group comparison and score change during admission were conducted for six age groups: 18–24, 25–34, 35–44, 45–54, 55–64 and 65+. Younger patients improved on most measures whereas older patients aged 55–65+ showed little improvement or deterioration over time. This finding suggests that the subscales are sensitive to age difference although the needs measured by HoNOS-secure are less likely to inform the decision to discharge. 相似文献

Within a social learning model, family-of-origin violence places men at risk for developing negative communication in their adult relationships. Thirty young men exposed to family-of-origin violence (exposed group) and 30 unexposed young men were videotaped discussing a conflict topic with their female dating partners. Relative to the unexposed group, the exposed men and women reported higher relationship aggression and during discussion showed more negative communication, were more domineering, and the men reported more negative affect. There were no differences between the groups on cognition or heart rate. The conflict management deficits and aggression evident in the exposed group suggest that these partners are at high risk for future relationship aggression and distress. 相似文献

This article examines the claim that, by the late 1980s, the Welsh Office possessed sufficient autonomy to implement policies that diverged from those of the functional Whitehall ministries. Two case studies, housing and education, are examined as these are areas where institutional autonomy and distinctive needs might be expected to be most apparent in Wales. The conclusion of this article is that the claims of Welsh exceptionalism (certainly in terms of policies) have been much exaggerated and that the 'centre', Westminster and Whitehall, was able to impose its preferred policies in Wales, whatever appearances to the contrary. 相似文献

This study examines the conditions under which an intervening lineup affects identification accuracy on a subsequent lineup. One hundred and sixty adults observed a photograph of one target individual for 60 s. One week later, they viewed an intervening target-absent lineup and were asked to identify the target individual. Two days later, participants were shown one of three 6-person lineups that included a different photograph of the target face (present or absent), a foil face from the intervening lineup present or absent), plus additional foil faces. The hit rate was higher when the foil face from the intervening lineup was absent from the test lineup and the false alarm rate was greater when the target face was absent from the test lineup. The results suggest that simply being exposed to an innocent suspect in an intervening lineup, whether that innocent suspect is identified by the witness or not, increases the probability of misidentifying the innocent suspect and decreases the probability of correctly identifying the true perpetrator in a subsequent test lineup. The implications of these findings both for police lineup procedures and for the interpretation of lineup results in the courtroom are discussed. 相似文献
