Shells and Bones: A Forensic Medicine Study of the Association of Terrestrial Snail Allopeas micra with Buried Human Remains in Brazil

Little is known regarding the scavenger fauna associated with buried human corpses, particularly in clandestine burials. We report the presence of 20 shells of the terrestrial snail Allopeas micra, within hollow bones of human remains buried for 5 years, during the process of collecting DNA material. The fact that a large number of shells of A. micra had been found in the corpse and in the crime scene supports the assumption that there was no attempt to remove the corpse from the area where the crime occurred. Despite this, our observations cannot be used to estimate the postmortem interval because there is no precise knowledge about the development of this species. This is the first record of a terrestrial snail associated with a human corpse and its role in this forensic medicine case.     

Location Efficiency and Mortgage Risks for Low-Income Households

Abstract

Household energy expenditures, especially for transportation, are fairly inelastic. Their effects on low-income households may be significant, due to the potential for energy consumption to displace other types of consumption when energy prices rise. Using accessibility as a proxy for lower transportation costs, we test the hypothesis that low- and moderate-income residents are less likely default when they are located in more accessible places. We find that regional accessibility has almost no effect on risks of default, but local job diversity has moderate mitigating effect.     

Linking ammonium nitrate-aluminum (AN-AL) post-blast residues to pre-blast explosive materials using isotope ratio and trace elemental analysis for source attribution

Forensic science practitioners are often called upon to attribute crimes using trace evidence, such as explosive remnants, with the ultimate goal of associating a crime with a suspect or suspects in order to prevent further attacks. The explosive charge is an attractive component for attribution in crimes involving explosives as there are limited pathways for acquisition. However, there is currently no capability to link an explosive charge to its source via post-blast trace residues using isotope ratios or trace elements. Here, we sought to determine if pre-blast attribution signatures are preserved after detonation and can be subsequently recovered and detected. A field study was conducted to recover samples of post-blast explosives from controlled detonations of ammonium nitrate-aluminum (AN-Al), which were then analyzed via isotope ratio mass spectrometry (IRMS) and inductively coupled plasma-mass spectrometry (ICP-MS) for quantitation and profiling of isotopes ratio and trace element signatures, respectively. Oxygen and nitrogen isotope ratios from AN-Al yielded some of the most promising results with considerable overlap within one standard deviation of the reference between the spreads of pre- and post-blast data. Trace element results from AN-Al support the findings in the isotope ratio data, with 26 elements detected in both pre- and post-blast samples, and several elements including B, Cd, Cr, Ni, Sn, V, and Zn showing considerable overlap. These preliminary results provide a proof-of-concept for the development of forensic examinations that can attribute signatures from post-blast debris to signatures in pre-blast explosive materials for use in future investigations.     

Coups d’état and defense spending: a counterfactual analysis

We explore how institutional set-ups, in particular changes in political institutions through coups d’état, can affect the way military expenditures are determined. We use a counterfactual approach, the synthetic control method, and compare the evolution of the military burden for 40 countries affected by coups with the evolution of a synthetic counterfactual that replicates the initial conditions and the potential outcomes of the countries of interest before exposure to coups. Our case studies suggest that successful coups result in a large increase in the military burden. However, when no effects or a decrease in the defense burden are found, it is often the consequence of a democratization process triggered by the coup. These results are in keeping with recent theoretical developments on the bargaining power of the military in authoritarian regimes. Failed coups, by contrast, produce a smaller, and mostly positive, effect on the military burden, possibly as a result of the incumbent’s strategy to avert further challenges to the stability of the regime by buying off the military.     

The East African community and Europe

The European Union and Russia are preparing to negotiate a new comprehensive agreement at a time when their bilateral relations have become increasingly prickly. On the one hand, Vladimir Putin's Russia is perceived as having gone undesirably far in reverting to a semi-authoritarian state and in exerting economic and political pressures on some pro-Western, former Soviet states. On the other hand, the EU's Russia policy remains ambivalent because of the continuing deference towards Moscow of a number of large European countries and the confrontational posture of some new EU member states. Other factors add to this deteriorating state of affairs. For one, there are a number of legal complications coming from the shape and scope of the new agreement. Perhaps more importantly, there are several political uncertainties, first and foremost the definition of those “common values” upon which the new treaty should be based. To get out of this quandary, the two sides will have to scale down their ambitions on the new agreement. A mutually acceptable formula might imply the negotiation of a concise “framework” treaty, accompanied in due time by sector-specific agreements.
