This study investigates the optimisation of peroxidase based enhancement techniques for footwear impressions made in blood on various fabric surfaces. Four different haem reagents: leuco crystal violet (LCV), leuco malachite green (LMG), fluorescein and luminol were used to enhance the blood contaminated impressions.The enhancement techniques in this study were used successfully to enhance the impressions in blood on light coloured surfaces, however, only fluorescent and/or chemiluminescent techniques allowed visualisation on dark coloured fabrics, denim and leather. Luminol was the only technique to enhance footwear impressions made in blood on all the fabrics investigated in this study. 相似文献

Individuals with severe mental illness (SMI) are at risk for HIV/AIDS. Despite the availability of supportive community programs for those with SMI, there have been no published evaluations of community-level HIV prevention trials among this population. A pilot intervention trial was conducted to determine the feasibility of such an intervention in supportive housing programs (SHPs). A multi-component community-level trial was implemented in two SHPs with a total of 28 residents. Participants completed assessments at three time points: prior to the intervention (baseline), following skills training (post-assessment), and following the 4-month community intervention (follow- up). Results demonstrated significant improvements in psychosocial risk factors at both post- and follow-up assessments, with indications of sexual behavior change at follow-up. The community-level intervention appeared to reduce the risk of HIV among persons with SMI living in SHPs, and supports the importance of conducting larger scale intervention trials. 相似文献

Recent U.S. cases of murders by children below age 11 have captured national headlines. A review of the literature reveals that little is known about this population of juvenile homicide offenders (JHOs). Most studies on juvenile murderers have used small clinical samples, focused on adolescents, and concentrated on male offenders. Studies that have used Supplementary Homicide Report (SHR) data have found significant gender differences among juveniles below 18 years arrested for murder. This study investigated gender differences among 226 juvenile murderers ages 6 through 10 involved in single-victim incidents using bivariate and multivariate statistical techniques. Consistent with previous research, bivariate analyses revealed gender differences with respect to the type of weapon used, age of the victim, relationship to the victim, and circumstances of the crime. Logistic regression analysis identified female JHOs as more likely to use a knife, kill a family member, and kill a victim below age 5, when compared with male JHOs. From these findings, profiles of young male and female JHOs can be drawn. The article concludes with a discussion of the study's implications for prevention and treatment. The authors recommend that future research in gender differences among young children focus on examining psychological, neurological, and sociological variables not included in the SHR data set. 相似文献

Footwear impression lifting and enhancement techniques may be affected by several variables introduced during the production of test footwear impressions, thus limiting the usefulness of enhancement technique comparisons and the results obtained. One such variable is the force applied when the impressed mark is being made. Producing consistent test impressions for research into footwear enhancement techniques would therefore be beneficial. This study was designed to control pressure in the production of test footwear impressions when mimicking a stamping action. Twenty-seven volunteers were asked to stamp on two different surfaces and the average stamping force was recorded. Information from the data obtained was used to design and build a mechanical device which could be calibrated to consistently deliver footwear impressions with the same force onto a receiving surface. Preliminary experiments using this device and different contaminants on the footwear sole have yielded consistent and repeatable impressions. Controlling the variable of pressure for the production of test impressions in this study demonstrated that the differences observed were visual (due to the amount of contaminant transferred and subsequent enhancement) and did not affect the replication of outer sole characteristics. This paper reports the development of the device and illustrates the quality of the impressions produced. 相似文献

When confronted with coercive threats, targets often stand firm rather than back down. We identify one important yet unrecognized factor that causes actors to resist threats: psychological reactance. Reactance theory explains that when someone perceives a threat to their freedom to make choices, they attempt to restore their autonomy by refusing to capitulate. The result is unwillingness to concede to coercion that extends beyond rational incentives. We test for reactance as a cause of coercion failure with two novel experiments. Each experiment pairs a coercive threat treatment with a matched “natural costs” counterpart that imposes the same choice on the target without intentional action by a coercer. Controlling for prominent alternative explanations, including costs, benefits, power, credibility, and reputation, we find that the targets of threats capitulate less frequently and more often support aggression against their opponents. 相似文献

AbstractThree decades ago, a civic movement arose in the USSR around commemorating Stalin’s victims. Yet only in 2017, following President Vladimir Putin’s approbation, was a central monument to victims of repression constructed. Analysis of the genesis and results of the design process for the new monument shows that memory discourses in Russia have been harnessed to a form that allows civic activists and state officials to express a limited consensus. The truncated nature of the competition and the jury’s safe choice, however, produced a monument unlikely to become a locus for popular or official remembrance. 相似文献

This article draws on ethnographic research into a state-funded homecare service in rural Russia. The article discusses intersections between care, work and kinship in the relationships between homecare workers and their elderly wards and explores the ways in which references to kinship, as a means of authenticating paid care and explaining its emotional content, reinforce public and private oppositions while doing little to relieve the tensions and conflicts of care work. The discussion brings together detailed empirical insights into local ideologies and practices as a way of generating new theoretical perspectives, which will be of relevance beyond the particular context of study. 相似文献

This commentary discusses and expands upon Mosten and Traumm's extraordinary work on interdisciplinary teams. Focusing on the continuum between independence and interdependence in team formation, we explore the benefits of team members' shared responsibility and highlight potential challenges. We emphasize that regardless of where a team may fall on the continuum, establishing and adhering to a strong structure results in increased practitioner satisfaction and better client outcomes. This commentary identifies five best practices that promote highly functioning teams and urges family law practitioners to seek more advanced interdisciplinary team training opportunities. 相似文献
