There is increasing evidence that some individuals actively seek to bring about their own deaths by provoking armed police officers to shoot them. The current paper examines 22 police shooting incidents, nine fatal, between 1998 and 2001, to assess the likelihood of suicidal motivation in each of these cases. All 22 individuals shot were male, 18 were white, three black and one Asian and ages ranged from 18 to 51. Around half of the shootings examined have some evidence indicating a suicidal motive in those shot, with further indications of irrational behaviour in a number of the other cases. This has clear implications for the choice of police strategy in responding to such incidents and an imperative to develop ‘less lethal’ options to minimise the risk to such vulnerable populations. 相似文献

To explore the impact of the press in Britain during the first New Labour administration, we used aggregate-level analysis to assess the relationship between the economic content of press and changes in the public's political and economic attitudes. We examine the effects on attitudes of economic coverage in the broadsheets, 'black top' and tabloid newspapers. The results suggest that the broadsheets and 'black tops' do exert an influence on voters' views, whereas the tabloids do not. The impact is, however, not global, but confined to particular segments of the population. The modest effects we have charted, nevertheless have important cumulative political significance in the medium- to long-term, and they put press influence into sharper and more realistic perspective than many current accounts. Methodologically our results suggest the need for further work to focus on press effects on specific groups of voters. 相似文献

Conventional Gas Chromatography‐Mass Spectrometry (GC‐MS) methods for the analysis of ignitable liquids (ILs) are usually time‐consuming, and the data produced are difficult to interpret. A fast IL screening method using direct analysis in real time mass spectrometry (DART‐MS) is proposed in this study. GC‐MS, QuickStrip DART‐MS, and thermal desorption DART‐MS methods were used to analyze neat ILs and thermal desorption DART‐MS without extraction was used to analyze ILs on five substrates (e.g., carpet, wood, cloth, sand, and paper). Compared to GC‐MS, DART‐MS methods generated different spectral profiles for neat ILs with more peaks in the higher mass range and also provided better detection of less volatile compounds. ILs on substrates were successfully classified (98 ± 1%) using partial least squares discriminant analysis (PLS‐DA) models based on thermal desorption DART‐MS data. This study shows that DART‐MS has great potential for the high‐throughput screening of ILs on substrates. 相似文献

ABSTRACTThis mixed methods study describes attributions for improvement following reductions in victimization for children who were bullied at school. It also tests hypotheses from attribution theory about attributions associated with improvements. The sample was a subset of families who participated in an RCT of a family cognitive-behavioral program to reduce victimization; to be included, both the parent and child needed to report reductions in child victimization at 9 months. Attributions were compared across conditions, respondents (parents versus children) and time. Both parents and children attributed improvements most often to actions by the target child. Intervention families were more likely than control families to attribute changes to their own efforts than to external factors. The relevance of internal attributions for the success of interventions is discussed. 相似文献

This paper describes the process of change in attitudes of male social workers’ towards themselves and towards their clients who are male perpetrators of partner violence (PV). The process reveals a reconstruction of the therapist’s beliefs concerning key elements in their work related being, such as masculinity, aggression, perception of their clients and their own male identities. The sample includes 15 male social workers that worked with battering men in social services. Data collection was performed through semi-structured interviews. The therapists’ process of questioning the popular and accepted demonization of violent men clarifies what differentiates them from their clients, but also opens an authentic pathway to examining similarities they share as men, without the need to be politically correct or to conform. The implications for practitioners working in batterers’ intervention programs are addressed. 相似文献

Taking the reforms of child protection legislation that have occurred since the 1980s as a backdrop, this paper considers young people’s perspectives on the factors that facilitated their engagement with child protection services and the barriers they perceived to effective service delivery. Drawing on findings from a New Zealand study of young people’s experience of multiple service use (child protection, mental health, youth justice and remedial education), the paper identifies that that rather than being ‘resistant’ or ‘hostile’ to statutory child protection intervention, young people reported a ‘conditional openness’. This conditional openness was characterised by three themes: communication; continuity and consistency; and contextual and cultural responsiveness. Interventions with these characteristics activated this conditional openness allowing effective interventions to occur. Using a series of case studies, comprising interviews and agency case file records; the paper considers the experiences of 109 young people (12–17 years) as well as those of the ‘person most knowledgeable;’ an adult nominated by young people because they knew the young person’s situation well. 相似文献

An Optimized Centrifugal Method for Separation of Semen from Superabsorbent Polymers for Forensic Analysis 下载免费PDF全文

Connection of a perpetrator to a sexual assault is best performed through the confirmed presence of semen, thereby proving sexual contact. Evidentiary items can include sanitary napkins or diapers containing superabsorbent polymers (SAPs), complicating spermatozoa visualization and DNA analysis. In this report, we evaluated the impact of SAPS on the current forensic DNA workflow, developing an efficient centrifugal protocol for separating spermatozoa from SAP material. The optimized filtration method was compared to common practices of excising the top layer only, resulting in significantly higher sperm yields when a core sample of the substrate was taken. Direct isolation of the SAP‐containing materials without filtering resulted in 20% sample failure; additionally, SAP material was observed in the final eluted DNA samples, causing physical interference. Thus, use of the described centrifugal‐filtering method is a simple preliminary step that improves spermatozoa visualization and enables more consistent DNA yields, while also avoiding SAP interference. 相似文献
