The chemical composition of fingermarks could potentially be important for determining investigative leads, placing individuals at the time of a crime, and has applications as biomarkers of disease. Fingermark samples containing triacylglycerols (TAGs) and other components were analyzed using laser desorption/ionization (LDI) time-of-flight mass spectrometry (TOF MS). Only LDI appeared to be useful for this application while conventional matrix-assisted LDI-TOF MS was not. Tandem MS was used to identify/confirm selected TAGs. A limited gender comparison, based on a simple t-distribution and peaks intensities, indicated that two TAGs showed gender specificity at the 95% confidence level and two others at 97.5% confidence. Because gender-related TAGs differences were most often close to the standard deviation of the measurements, the majority of the TAGs showed no gender specificity. Thus, LDI-TOF MS is not a reliable indicator of gender based on fingermark analysis. Cosmetic ingredients present in some samples were identified. 相似文献

Abstract: Effective removal of fingerprint deposits is crucial for experimentation related to the corrosion of metals by fingerprint deposits. Such removal is also necessary prior to deposition of test fingerprints. The effectiveness of four regimes in removing fingerprint deposits from brass is considered. Sustained wiping of the deposit with a tissue at applied pressures of up to c . 1430 Pa or rubbing while the brass was immersed in acetone both failed to remove completely all traces of fingerprint deposits. Heating the brass to 600°C was an effective remover; however, this also oxidized the surface of the metal except where inhibited by fingerprint deposits. The most effective regime, and the only one of the four that removed all traces of deposit without affecting the properties of the metal surface, was immersion in warm soapy water while rubbing with a tissue. We propose this as the preferred method for fingerprint removal. 相似文献

From ‘Doctor Knows Best’ to Dignity: Placing Adults Who Lack Capacity at the Centre of Decisions About Their Medical Treatment

In 1989, the House of Lords first derived a ‘best interests’ test for the medical treatment of adults who lack capacity from the doctrine of necessity and, now codified, the test continues to apply today. The Mental Capacity Act 2005 sets out a non‐exhaustive checklist of relevant considerations, but it gives no particular priority to the patient's wishes. There is also no formal expectation that the patient will participate directly in any court proceedings in which her best interests are to be determined. This article will consider the advantages and disadvantages of providing additional guidance to decision‐makers in order to help them navigate both taking seriously the wishes of people who lack capacity and, at the same time, not abandoning patients who need help and support. More specifically, this article advocates formalising current best practice in the Court of Protection through the introduction of a series of rebuttable presumptions, or starting points. 相似文献

Educational attainment is a fundamental cornerstone to success throughout the life-course. As a result, ensuring that young people remain in school and are not truant is critical. Although the importance of truancy as a risk factor for many adverse outcomes, including crime, has been well-documented, much less methodologically rigorous work has been undertaken to evaluate potentially promising prevention and intervention strategies. This paper uses a randomized field trial method to test how a partnership between police and schools targeting truancy impacts offending in a sample of high-risk truanting young people. We find that the truancy intervention reduces offending and we discuss the implications for practice and directions for future research. 相似文献

ABSTRACTChildren under 10 are increasingly being referred to services for concerning problematic or harmful sexual behaviour, but information about interventions to support these children and their families is limited. A 3-year pilot of a group cognitive–behavioural intervention for children and their parents/carers is described. Forty-nine children were referred to the programme with 27 completing the programme in this period. This is the first intervention of its kind to be delivered with a UK population and demographic information is provided about the children who have been assessed, including information about age, gender, family composition and abuse history. Outcome data from the Trauma Symptom Checklist for Children, Child Sexual Behaviour Inventory, Strengths and Difficulties Questionnaire and the Parental Stress and Social Support Scale is reported. The available outcome data indicates the group has been largely beneficial in reducing problematic sexual behaviour. Key learning and implications for practice are discussed. 相似文献

Through analyzing the various factors in R2P's genesis and expansion as an international norm, this article contends that the office of the UN Secretary-General has provided steady backing of R2P, allowing for its ongoing consideration within the UN bureaucracy and among member states. In this respect, R2P has been able to assert itself in a meaningful way, with member states compelled to revisit the central tenets of the norm within the General Assembly and special dialogues. The office of the Secretary-General has clearly interpreted R2P as a strong and effective reinforcement of Article 1 of the UN Charter and the overall UN mandate, using the norm to more strongly anchor existing UN principles and values. 相似文献
