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.

One or two arenas? The break-up between national and regional elections

ABSTRACT

This paper shows that the role of national electoral dynamics on regional elections is highly mediated by institutional and electoral constraints at the regional level. Using data on statewide parties’ electoral competition in regional and national elections in Spain and Italy, results show that the contamination of regional elections is lower in regions where decentralization has travelled further and where strong regionalist parties dominate electoral competition. The paper also shows that these two channels -more regional authority and more regionalist competition- shape the regional manifestos of statewide parties by increasing their pro-regional positions. These findings represent a contribution to a better understanding of the extent to which regional elections are a separate electoral arena from the national one.     

Does regulating remuneration affect the market value of European Union banks? Large versus small/medium sized banks

The aim of this paper was to analyze equity market reactions to the mandatory European Union regulation of remuneration policies in financial institutions. Using event study methodology, we investigated market reactions to the first European Directive on compensation policies after the financial crisis using a sample of 124 banks operating in the European Union. We divided the sample into two groups according to bank size considering four criteria: the US Dodd‐Frank Act 2010, the Liikanen Report 2012, Global Systemically Important Banks 2011, and the European Central Bank 2014. We found strong evidence of an average negative market reaction to compensation regulation. Moreover, this negative reaction is stronger for large banks than for small/medium sized banks.

Capable,splendorous and unequal: international media portrayals of Brazil during the 2014 World Cup

This article examines how Brazil was perceived internationally during the 2014 World Cup (2014WC), for which one of Brazil’s perceived objectives was to enhance its international image to play a more significant role on the world stage. Nine media outlets’ coverage of the 2014WC was analysed using the website Alexa. These outlets published 699 articles about diverse themes relating to Brazilian society. The outlets studied considered the event a success overall and emphasised Brazil’s natural beauty, but raised concerns about social problems such as inequality. We conclude that the 2014WC updated but did not fundamentally alter Brazil’s international image.
