Exploitation of the Ultraviolet Properties and Machine Cut Edges of Paper to Associate and Sequence Sheets in a Ream 下载免费PDF全文
Nicola R. Musgrave B.Sc. M.Sc. Oliver T. S. Thorne B.Sc. 《Journal of forensic sciences》2018,63(5):1450-1456
Previously unreported line patterns visible under ultraviolet light were observed on a proportion of plain white A4 printer/copier paper from different manufacturers. These Ultraviolet Line Patterns (UVLPs) usually appear as stripes down the vertical length of the paper. Typically, the UVLPs were found to “repeat” through the ream in a predictable way, while also changing. It is postulated that the repeating nature of the UVLPs is a result of the way that paper is manufactured. This leads to the ability to sequence the sheets compared to their original source paper. Even in the absence of UVLPs, it is possible to use our observation of the manufacturing process to anticipate the order of several sheets of paper and conclusively associate them, in some cases, by physically fitting their machine cut edges and crossing paper fibers. Such a novel approach to examining questioned documents would be highly useful in forensic casework. 相似文献

ABSTRACTIn the context of the UK Government’s Offender Personality Disorder (OPD) Strategy, large numbers of high-risk young adult sexual offenders with emerging personality disorders are being screened for inclusion onto specialist intervention pathways (the OPD Pathway). However, little is currently known about the clinical and offence-related needs of this population or their impact on treatment engagement. The current study investigated the developmental, personality and offence-related characteristics of 87 incarcerated young adult sexual offenders, comparing those screened in to the pathway and those not screened in. Fifty per cent of the sample were potentially eligible for the OPD pathway. OPD eligible cases were found to have significantly higher rates of parental difficulties, developmental trauma, and childhood behavioural difficulties and to present with significantly higher rates of previous violent and sexual offences, previous allegations of sexual offences, and to have used physical coercion in their offences. The OPD sample was also significantly less likely to have pre-pubescent victims and more likely to refuse treatment, with over 70% failing to engage with the Sex Offender Treatment Programme (SOTP). SOTP non-engagement among OPD cases was most strongly predicted by categorical offence denial. Comparisons are made with the broader adolescent sexual offender literature. 相似文献

This article contributes to the literature on aid and economic growth. We posit that uncertainty, measured as the instability of aid receipts, will influence the relationship between aid and investment, how recipient governments respond to aid, and will capture the fact that some countries are especially vulnerable to shocks. When we account for uncertainty (which is negative and significant), we find that aid has a significant positive effect on growth, largely due to its effect on the volume of investment. The finding that uncertainty of aid receipts reduces the effectiveness of aid is robust. When the regression is estimated for the sub‐sample of African countries these findings hold, although the effectiveness of aid appears weaker than for the full sample. 相似文献

This article addresses three issues. First, it argues that the use of trade related investment measures (TRIMs) by LDCs can only be analysed in the context of their dealings with transnational corporations (TNCs). Second, it considers the applicability of existing GATT rules to TRIMs and shows that they are inadequate and can pose difficulties for LDCs seeking foreign direct investment by TNCs. Third, it suggests a framework for regulating TRIMs as one element of host‐TNC relations. The article concludes with proposals for enhancing the capacity of LDCs in their dealings with TNCs. 相似文献

Interventions aimed at increasing the supply and representativeness of elected officials range from facilitative to the formally authorised. This paper reports on a field experiment aimed at testing the effect of facilitative approaches at the local level based on a collaboration between parish councils and the research team. We randomly allocated 818 parish council clerks across five counties in Southern England, either to receive information and the opportunity for member training for recruitment, or not to receive this contact. We investigated the effect of this intervention on political recruitment. Despite evidence of an effect on use of social media, our results suggest that there are significant institutional and structural barriers to participation in local politics that cannot easily be overcome using facilitative measures. 相似文献
