Particle Analysis for the Detection of Gunshot Residue (GSR) in Nasal Samples Using Scanning Laser Ablation and Inductively Coupled Plasma-Mass Spectrometry (SLA-ICPMS)

Currently, aluminum stub with carbon adhesive devices are used to collect inorganic gunshot residues (GSR) from the hands of a shooter. In an ideal shooting case, the gunshot particles do not persist for more than 2 h in the hands of the shooter, provided that the hands have not been washed. However, for forensic analysis and inference, the extended persistence of GSR would be desirable. This study investigates a novel GSR sampling and detection protocol. Sampling was performed in the nostrils using swab devices impregnated in ethylenediaminetetraacetic acid (EDTA). The GSRs persisted for longer periods in nasal mucus than on the hands, and particles were detected 6 h after shooting occurred. The analytical determination was conducted by scanning laser ablation-inductively coupled plasma-mass spectrometry (SLA-ICPMS) which enable the identification of the number of particles and their elemental composition. Seventeen isotope signals corresponding to ¹³C, ²⁰⁵Tl and 15 analytes that are usually associated with the composition of GSR residues were monitored: ²⁷Al, ²⁹Si, ³¹P, ³³S, ³⁵Cl, ³⁹K, ⁴⁴Ca, ⁵⁷Fe, ⁶⁰Ni, ⁶³Cu, ⁶⁶Zn, ¹¹⁸Sn, ¹²¹Sb, ¹³⁷Ba, and ²⁰⁸Pb. The SLA technique enabled the reduction of the swab analysis time to 40 min. The effectiveness of this methodology was evaluated with two types of firearms: a pistol and a shotgun. The results indicated that the methodology proposed for the analysis of the nasal GSR was effective and that it can improve or complement the forensic analyses and inferences presented in a court.

Outsourcing,bureaucratic personnel quality and citizen satisfaction with public services

This article investigates the relationships between outsourcing, bureaucratic personnel quality (BPQ) and citizen satisfaction with public services. Our baseline expectation is of a negative association between outsourcing and service quality; however, we argue that this tendency can be counteracted when the government buyer has a more competent and motivated personnel, not only in managerial positions, but across the board. Better‐educated and paid public employees are likely to have an important moderating effect on service quality through their input into quality specifications, their ability to recognize the provider's consummate or perfunctory behaviour, and their willingness to act on the observed performance. Using data from a cross‐section of Sweden's municipalities, our analysis reveals a robust association between higher levels of outsourcing and lower levels of citizen satisfaction, but the data do not provide unambiguous support for the hypothesis that the strength of this association diminishes when BPQ is higher.     

The Kremlin and the Government Do Not Agree with the Duma

At the last session of the Duma, the deputies adopted amendments to the law on local self-government, allowing the reform, against which the governors have as a body been actively speaking out recently, to be "forgotten" for a time by the regions.     

Networked Cooperation: How the European Union Mobilizes Peacekeeping Forces to Project Power Abroad

Abstract

How does the European Union (EU) recruit troops and police to serve in EU peacekeeping missions? This article suggests that pivotal EU member states and EU officials make strategic use of the social and institutional networks within which they are embedded to bargain reluctant states into providing these forces. These networks offer information on deployment preferences, facilitate side-payments and issue-linkages, and provide for credible commitments. EU operations are consequently not necessarily dependent on intra-EU preference convergence—as is often suggested in the existing literature. Rather, EU force recruitment hinges on highly proactive EU actors, which use social and institutional ties to negotiate fellow states into serving in an EU missions.     

Gender inequality in Russia's rural formal economy

Gender inequality in Russia's rural formal economy is examined using quantitative and qualitative data. Rural women continue to be underrepresented in farm managerial positions, and gendered income differences remain the norm. Rural women are underrepresented because they continue to have responsibility for most of the housework and child care. The traditional division of labor inside the household continues to dominate, thereby affecting women's career trajectories and earning potential. Value change about gendered roles in the formal economy has been minimal.     

A Multidimensional Approach to Ascertaining Individual Differentiation and Consistency in Serial Sexual Assault: Is It Time to Redefine and Refine?

Whilst investigative use of behavioural evidence to help link and solve serial offences has long been in use, the empirical and theoretical grounds for whether and how to use this evidence effectively have begun to emerge only in recent decades. The present study empirically tested (a) the potential for effectively differentiating between rape offence crime scenes using quantitative and qualitative distinctions within the behavioural dimensions of control, violence, and sexual activity, and (b) the extent to which redefining behavioural consistency more broadly to include dynamic trajectories of behavioural change may be more effective than limiting this definition to behavioural stability. Results confirmed that sexual offences can be successfully differentiated based on the specific degree and subtype of these behavioural dimensions present in each crime scene. The analysis of consistency and behavioural trajectories showed that whilst none of the offenders exhibited complete consistency across behavioural dimensions, a subsample of offenders remained fully consistent in at least one. Furthermore, of those who were not consistent, the vast majority followed an identifiable trajectory of change. Findings are discussed in the context of psychological theories of behavioural consistency as well as practical aspects of advancing the utility of behavioural linkage.     

Social Media as a Leverage Strategy for Open Government: An Exploratory Study

Social media are regarded to be a cornerstone for addressing the open government challenge that public administration faces. However, scientific knowledge about how social media can leverage open government is limited. Therefore, this study applies a mixed-methods research proceeding to develop a conceptual framework for the strategic use of social media concerning open government initiatives. The study concludes that social media applications can be strategically applied to foster open government and to improve citizen–government interaction. From the findings, strategic recommendations for open government-related social media adoption are developed and practical advice for responsible public managers is given.     

Diatoms in forensic expertise of drowning--a Macedonian experience

Results obtained by examination of 22 human cases suspected for drowning, one human case of death other than drowning and several tests on laboratory rats were used as a basis for evaluation of diatom method as supportive in forensic expertise of drowning. The recovery of diatoms from various examined organs, their qualitative and quantitative composition, if properly treated without the possibility of contamination, can be a reliable proof of the time and place of drowning. The priority of organ examination (external microflora determination, lungs, brain, heart (and/or blood), stomach, liver and kidney, and finally bone marrow) is discussed and established as well as the basic future research on cases suspected of drowning, but also on non-drowned victims and laboratory animals.
