Screening of gunshot residues using desorption electrospray ionisation-mass spectrometry (DESI-MS)

Several studies have indicated that there are potential environmental sources of particles resembling inorganic primer found in gunshot residues (GSR); as a consequence examiners are reluctant to unambiguously assign the origin of inorganic particles. If organic gunshot residues (OGSR) were found in combination with inorganic particles, the possibility of environmental sources could be potentially eliminated, thereby significantly enhancing the strength of the evidence. Methods have been previously described whereby GSR specimens can be analysed for the presence of OGSR or inorganic GRS (IGSR). However, no methods have been reported that allow the analysis of both OGSR and IGSR on the same specimen. Described in this article is a direct method using desorption electrospray ionisation-mass spectrometry (DESI-MS) for the detection of methyl centralite (MC), ethyl centralite (EC) and diphenylamine (DPA) on adhesive tape GSR stubs typically used for scanning electron microscopy-energy-dispersive X-ray (SEM-EDX) analysis. The optimisation of numerous parameters was conducted using an experimental design. The results indicate that direct analysis of these organic components of GSR is possible although some limitations were also identified. This initial investigation has also indicated that subjecting stubs to DESI analysis does not interfere with subsequent SEM-EDX analysis of primer residues; therefore the technique described herein allows a comprehensive examination of GSR that would be highly probative in the event that both OGSR and IGSR are detected in the same specimen.     

Share and Share Alike? Hedge Funds,Human Rights,and Owning Enterprise in Britain

This article explores the meanings of ownership and shareholding in the context of the 2007 run on Northern Rock, its subsequent nationalization in 2008, and the resulting legal challenge brought by former shareholders. Drawing on evidence from a range of sources outside traditional legal and official doctrine, and from original empirical research, it focuses on the perspective and voices of local small individual shareholders in relation to shareholding, bank failure, and government responses to financial crisis. It tells the story of these individual shareholders against differing conceptions of share ownership rights and responsibilities, and from various angles, to show the many different subjectivities of corporate shareholding and ownership of enterprise of which orthodox legal and economic models take scant account. It concludes on a note of historic persistence in demand for proprietary shares in banking institutions, despite the differing levels of understanding and tolerance of equity risk among shareholders that our research reveals.     

The life conditions of Australian ex-prisoners: an analysis of intrapersonal, subsistence, and support conditions

Successful reintegration of ex-prisoners into the community is multifaceted. The life conditions of 36 adult Australian ex-prisoners (20 male and 16 female) were examined via a questionnaire administered at 1 to 4 weeks post release, and a subset of 19 of the original respondents were interviewed again at 3 to 4 months post release. Interviews focused on intrapersonal conditions (physical and psychological health and substance use), subsistence conditions (housing, employment, and finance), and support conditions (social support, support services/program participation, and criminal justice support). The majority of ex-prisoners self-reported chronic physical and mental health problems as well as a history of substance use and/or current substance use. Although the housing conditions of ex-prisoners were largely favourable and constant, the employment and financial conditions of this group were generally unfavourable. Level of social support was variable. Theoretical implications and practical applications of the present investigation for reintegration theory are discussed.

Utility of dorsal pits and pubic tubercle height in parity assessment

Parity indicators in human skeletal material are highly desirable yet elusive. In this study, the relationships of dorsal pits and pubic tubercle elongation to parity are investigated in a sample of 148 modern female sets of pubic bones with associated birth information. The elongation of the pubic tubercle shows no significant correlation with number of births, but instead is associated with the distance this feature is from the pubic symphysis (p < 0.01) and the size of the arcuate angle (p < 0.05). Dorsal pits show a strong association with increasing numbers of births (p < 0.01), especially in younger women. However, in women over 50 years old, dorsal pitting is correlated with BMI (p < 0.05) and is not significantly correlated with number of births. While this study lends support to the correlation of dorsal pitting and parity, it currently does not reach the level of accuracy needed for forensic applications at the level of the individual.     

ENVIRONMENTAL MONITORING; A CASE OF LEARNING THROUGH EVALUATION?

The aim of environmental monitoring programs is to provide information useful in enforcing existing environmental statutes and helping to detect and prevent future problems. Despite the considerable number of monitoring programs being conducted, information on the quality of the nation's environment remains poor and of little use in supporting environmental policymaking. This paper examines the role evaluation has played in developing an effective nationwide environmental monitoring system. Background information on environmental monitoring programs is provided, followed by a discussion of the evaluations of past programs and recommendations made for improvement. One program in particular, the "Status and Trends" program administered by the National Oceanic and ATmospheric Administration, is examined to explore whether environmental monitoring demonstrates a case of learning through evaluation. "Status and Trends" is based on the experience gained during several of the previous monitoring programs and incorporates many of the recommendations spawned from earlier environmental programs. Whether the program demonstrates a case of learning through evaluation will depend on the ability of the program to evolve as we learn more about environmental quality and out ability to measure it.     

Human rights is not enough: The need for demonstrating efficacy of an ethical approach to interviewing in India

Purpose. The present study compared attitudes about Human Rights (HR) and the advocation of coercive interviewing practices amongst Indian Police Officers, Offenders and a sample from the General Public. Method. 100 Police Officers, 50 Offenders and 50 members of the General Public completed a questionnaire that assessed their attitudes about the Human Rights of suspects and the use of coercion in suspect interviews. Results. Police Officers and the Public accepted both custodial violence and the use of intimidating interrogation strategies more readily than Offenders. They were also more prepared to suspend Suspects' Human Rights. Further, individuals who scored high on a coercive belief scale (CBS) were particularly inclined to favour custodial violence and suspend Human Rights. In addition, the self‐reported frequency with which Police Officers used intimidating and non‐intimidating interviewing techniques was related to their beliefs about Suspects' Human Rights and the extent to which they perceived intimidating interviewing methods to be useful. Conclusion. Attitudes about effective interviewing strategies may well be embedded within a broad social context. The effectiveness of a Human Rights Agenda requires that officers in India are informed of the effectiveness of ethical interviewing standards and the practical and legal dangers of using inappropriate methods.
