Combined Collection and Analysis of Inorganic and Organic Gunshot Residues

Gunshot residue (GSR) analysis and their interpretation provide crucial information on a criminal investigation involving the use of firearms. To date, several approaches have been proposed for the implementation of a combined sampling and analysis of inorganic (IGSR) and organic GSR (OGSR). However, it is not clear at this stage if concurrent analyses of both types of residue might be detrimental to the analysis of IGSR currently applied in forensic laboratories. Thus, this work aims to compare and evaluate three different protocols for the combined collection and analysis of IGSR and OGSR. These methods, respectively, involve the use of a modified stub (with two halves, one for the detection of IGSR and the other for the analysis of OGSR); the sequential recovery of GSR with two stubs mounted with different adhesives (double-sided carbon tape and Tesa® TACK) and the sequential analysis of IGSR and OGSR from a single carbon stub following carbon deposition. The detection of IGSR was carried out using SEM-EDX, while OGSR analysis was performed using ultra-high-performance liquid chromatography–tandem mass spectrometry (UHPLC-MS/MS). Obtained results for experiments performed using Geco Sinoxid^® ammunition indicated that sequential analysis was the most suitable protocol for the combined collection and analysis of both IGSR and OGSR. A higher number of inorganic (characteristic and consistent) particles and higher concentrations of ethylcentralite, N-nitrosodiphenylamine, diphenylamine, and nitroglycerin were recovered with this method.     

Rural artisans and peasant mobilisation in the socialist international: The fasci siciliani

This article explores the conditions under which peasant cultivators and rural artisans participate in movements of social transformation, a case in point being the Fascio movement of Sicily in the late nineteenth century. It analyses the reasons why artisans could play a critical role in politicising local protest and articulating it with pan‐European socialist movements, by describing their relations to other classes in a differentiated peasant community.     

Developing the meat grab

‘Meat grabbing’ describes actually existing land deals undertaken for industrial meat production, either directly in the form of animal housing and stocking (confined animal feeding operations, or CAFOs), or indirectly in the form of monocrop grain and oilseed production for livestock feed. Meat grabbing is also a concept for analyzing the relationships between industrial meat regimes, food security politics and the global land rush, relationships which have not yet been sufficiently considered in research or in policy. Using China's reform-era meat revolution as an analytical case, this paper proposes meat grabbing as a concept with three broad goals: (1) to show how industrial meat complicates notions of food security and of food security land grabs, (2) to incorporate social inequalities and environmental injustices into the conceptualization and measurement of land deals and (3) to expand dispossession's domain to include relationships between people and agroecosystems. This is an initial exploration of the content and framing of meat grabs, intended to synthesize its core features and raise questions for further study.     

Is a Federal European Constitution for an Enlarged European Union Necessary? Some Preliminary Suggestions using Public Choice Analysis

In order to guarantee a further successful functioning of the enlarged European Union a Federal European Constitution is proposed. Six basic elements of a future European federal constitution are developed: the European commission should be turned into a European government and the European legislation should consist of a two chamber system with full responsibility over all federal items. Three further key elements are the subsidiarity principle, federalism and the secession right, which are best suited to limiting the domain of the central European authority to which certain tasks are given, such as defense, foreign and environmental policy. Another important feature is direct democracy, which provides the possibility for European voters to participate actively in political decision making, to break political and interest group cartels, and to prevent an unwanted shifting of responsibilities from EU member states to the European federal level.     

GC/MS determination of zolpidem in postmortem specimens in a voluntary intoxication

An ingestion of an unknown quantity of Ivadal (zolpidem) tablets in a case of drug abuse is described. The authors report a new and fast method of analysing and determining the zolpidem concentration in postmortem specimens. Quantitation of zolpidem was performed by ethyl acetate extraction from alkalinized body fluids before GC/MS analysis. The analyses were performed without any complex sample clean-up steps and with little sample material. Postmortem concentrations of zolpidem in body fluids are given. The proposed method is a rapid procedure of analysis in cases of deliberate poisoning with the sedative-hypnotic drug, zolpidem.
