Abstract: Blowfly larvae and porcine tissue contaminated with gunshot residue (GSR) were collected during summer and winter months, over a 37‐day and a 60‐day sampling period, respectively. Wound samples were microwave‐digested and analyzed by inductively coupled plasma mass spectrometry (ICP‐MS) for the detection of antimony, barium, and lead. During summer, the 37‐day sampling period encompassed all stages of decomposition, except skeletonization. The three elements were detected in larvae only on days 3 and 4 after death but were detected at significant levels in tissue samples throughout the entire sampling period. In winter, no significant decomposition was observed throughout the 60‐day sampling. Although temperatures were too low for blowfly activity, the three elements were detected in the tissue samples at relatively constant, significant levels. Hence, GSR determination in tissue was more dependent on decomposition stage rather than time since death. 相似文献

Abstract: The collection efficiency of two widely used gunshot residue (GSR) collection techniques—carbon‐coated adhesive stubs and alcohol swabs—has been compared by counting the number of characteristic GSR particles collected from the firing hand of a shooter after firing one round. Samples were analyzed with both scanning electron microscopy and energy dispersive X‐rays by an experienced GSR analyst, and the number of particles on each sample containing Pb, Ba, and Sb counted. The adhesive stubs showed a greater collection efficiency as all 24 samples gave positive results for GSR particles whereas the swabs gave only positive results for half of the 24 samples. Results showed a statistically significant collection efficiency for the stub collection method and likely reasons for this are considered. 相似文献

Abstract: Black powder substitutes containing ascorbic acid are a group of low explosives that utilize ascorbic acid as the fuel. The analysis of these powders is complicated by the degradation of ascorbic acid which occurs rapidly in solution and may also occur as the powder ages. Aqueous extracts of both intact powders and postblast residues were analyzed by an existing ion chromatography/mass spectrometry (IC/MS) method used at the Bureau of Alcohol, Tobacco, Firearms and Explosives. Results have shown that while ascorbic acid itself is not detected in this method, its diagnostic degradation products (threonic acid, monohydrated diketogulonic acid, and oxalic acid) can be identified. In addition, anions from the inorganic oxidizers (perchlorate and nitrate) and combustion products such as chloride, chlorate, and nitrite, can be identified within the same experiment. While this IC/MS method shows promise, future modifications are necessary because of limitations in identifying threonate in postblast residues, as well as coeluting compounds observed in postblast residues. 相似文献

Individuals with a disability who wish to use goods and services can have a variety of specific needs, ranging from accessible written information to standard products and services which have disability accessibility features built into them. In light thereof, this article focuses on the impact which Community law has had, and could potentially have, on ensuring an EU‐wide market in products and services which are accessible to consumers with a disability. The article examines the (possible) impact of a variety of provisions, including the rules relating to the free movement of goods and services (Articles 28 and 49 EC, respectively), the internal market (Articles 94 and 95 EC), non‐discrimination (Article 13 EC), EU citizenship provisions, and the work of the European standardisation bodies such as CEN. The central question throughout the article is does EC law allow for, or discourage, the establishment of mandatory disability accessibility standards at the national or EU level, and have the provisions been used to permit or establish such standards to date? 相似文献

Objectives. Few studies have examined the judgements made towards adolescent rape victims, and none have investigated attributions towards gay male or lesbian adolescents. The current study examined the effects victim gender, victim sexual orientation, victim response, and respondent gender, on attributions of blame in the depicted rape of a 15‐year old adolescent. Methods. A total of 164 respondents read details of this assault before completing 15 attribution judgments. Results. Respondents were expected to attribute more blame to a victim who was male, gay, and who failed to resist the perpetrator. Male respondents were also expected to be more blaming of the victim than females. Overall these hypotheses were supported. Conclusion. Results are discussed in relation to the role gender stereotypes and homophobia play within attributions blame in sexual assault cases. Specifically, it seems male adolescent rape victims are subjected to the same negative stereotypes as male adult victims. Implications and ideas for future research are considered. 相似文献

This article describes, and explains the rationales for, the establishment of an innovative program in which a law school and two social services agencies are collaborating in a mediation clinic that uses the transformative model of mediation to serve clients in cases that seem ideally suited to benefit from this approach to practice—so-called "PINS" (persons in need of supervision) cases involving conflict within families, between parents and their adolescent children. The article first describes the evolution of the PINS system and the changing views of its purpose, especially in New York State. It then offers a brief introduction to the unique features of the transformative approach to mediation and explains why that approach in particular is likely to mesh with current understandings of the needs of the families involved in these cases. Finally, the article describes the innovative "Family Solutions Program" and how it uses transformative mediation to help these families and suggests that experience of this program shows how use of the transformative model, in particular, could be valuable not only for clinical education but also for effective volunteer training and supervision in mediation programs generally. 相似文献

Legal education is in a period of rapid development driven by changing industry demands and developing technologies. This paper will describe an innovative pilot study which utilises new technologies to provide an alternative mode of teaching and learning to meet growing industry demands for graduates who are technologically savvy and have strong communication and collaboration skills. The pilot study redesigns a law unit combining a more traditional approach with an approach in which online collaboration is critical to student learning as a teaching and assessment tool. After completing an online collaborative activity as part of their assessment for the unit, students completed an online survey to identify their perspectives of the online collaborative experience. The online survey data was analysed to identify common themes and the experiences of students are shared in this paper. The paper provides an example of how instructors might take advantage of a learning design process, online tools and infrastructure to develop educational experiences which promote communication and collaboration within the law discipline. It will also include five recommendations to consider when including online collaboration in unit design for law students. 相似文献

Environmental surface sampling is crucial in determining the zones of contamination and overall threat assessment. Viability retention of sampled material is central to such assessments. A systematic study was completed to determine viability of vegetative cells under nonpermissive storage conditions. Despite major gains in nucleic acid sequencing technologies, initial positive identification of threats must be made through direct culture of the sampled material using classical microbiological methods. Solutions have been developed to preserve the viability of pathogens contained within clinical samples, but many have not been examined for their ability to preserve biological agents. The purpose of this study was to systematically examine existing preservation materials that can retain the viability of Bacillus anthracis vegetative cells stored under nonpermissive temperatures. The results show effectiveness of five of seventeen solutions, which are capable of retaining viability of a sporulation deficient strain of B. anthracis Sterne when stored under nonrefrigerated conditions. 相似文献

The number of U.S. states with criminal libel laws has been steadily declining since the 1960s, and the offense has been struck down in the United Kingdom and several former British colonies. In Canada, however, criminal libel not only continues to exist, but appears to be enjoying a resurgence, albeit one that has flown beneath the radar of Canadian lawyers, judges, and journalists, who frequently assert that criminal libel prosecutions are rare. The research reported in this article found more than 400 prosecutions since the beginning of the twenty-first century. While many of these cases were brought against people who disseminated sexual slurs against former romantic partners, in a substantial number of cases criminal libel law was used to punish citizens’ political speech, particularly speech critical of police or other justice system officials, a use wholly inconsistent with the Canadian Charter of Rights and Freedoms. 相似文献

Community-oriented social capital strategies and punitive-oriented policing approaches conflict. Establishing local networking initiatives with community-oriented policing at the centre lends itself to an assets-based policing approach, based on honouring, mobilizing and extending the assets of community members. Scholars argue about the need for comparative research on convergences and divergencies across subcultures on the streets and communities. Based on qualitative data gathered from working class communities in Scotland and Denmark in 2014, the article draws inspiration from community-generated theory of social capital to explore the micro-sociology of experiences and understandings about community–police integration policy initiatives. We use this perspective to argue that the building of positive inter-generational and police–community relationships is the result of social exchanges and officers’ use of what we call ‘constructive investment strategies’. Ironically, our insights from Scotland to Denmark also suggest what appear as positive achievements of community policing may instead intensify residents’ negative perceptions of police officers and organizations. In this way, the article illuminates the tangled and conflicted nature of these embedded symbolic interactions, social capital formations and the latter’s form as a potential positional and ‘tribal’ commodity. 相似文献
