Ethanol formation in unadulterated postmortem tissues

During the investigation of aviation accidents, postmortem samples obtained from fatal accident victims are submitted to the FAA's Civil Aerospace Medical Institute (CAMI) for toxicological analysis. During toxicological evaluations, ethanol analysis is performed on all cases. Many species of bacteria, yeast, and fungi have the ability to produce ethanol and other volatile organic compounds in postmortem specimens. The potential for postmortem ethanol formation complicates the interpretation of ethanol-positive results from accident victims. Therefore, the prevention of ethanol formation at all steps following specimen collection is a priority. Sodium fluoride is the most commonly used preservative for postmortem specimens. Several studies have been published detailing the effectiveness of sodium fluoride for the prevention of ethanol formation in blood and urine specimens; however, our laboratory receives blood or urine in approximately 70% of cases. Thus, we frequently rely on tissue specimens for ethanol analysis. The postmortem tissue specimens received by our laboratory have generally been subjected to severe trauma and may have been exposed to numerous microbial species capable of ethanol production. With this in mind, we designed an experiment utilizing unadulterated tissue specimens obtained from aviation accident victims to determine the effectiveness of sodium fluoride at various storage temperatures for the prevention of microbial ethanol formation. We found that without preservative, specimens stored at 4 degrees C for 96 h showed an increase in ethanol concentration ranging from 22 to 75 mg/hg (average 42 +/- 15 mg/hg). At 25 degrees C, these same specimens showed an increase ranging from 19 to 84 mg/hg (average 45 +/- 22 mg/hg). With the addition of 1.00% sodium fluoride, there was no significant increase in ethanol concentration at either temperature.     

Funding,capabilities and the use of child soldiers

Recent years have seen increased scholarly attention given to the issue of child soldiering. Primarily dedicated to the decision-making calculus of rebel groups, this body of work has generally emphasised supply-side versus demand-side arguments. We contribute to this growing literature by explicitly investigating a previously untested aspect of the latter. Prior scholarship has made vague references to a potential association between economic endowments and child soldiering, including natural resource wealth, but scant empirical attention has been given. We argue that the specific type of endowment has important consequences for the decision to utilise child soldiers. We argue access to and exploitation of lootable natural resources (e.g. gemstones) to be especially likely to promote the use of child soldiers due to their ease of access, the low skills required to harness them and the heightened likelihood that groups will become more profit-oriented. A systematic cross-national investigation of rebel groups provides robust evidence that lootable resources such as diamonds and gemstones are strongly associated with the use of children, while non-lootable resources such as oil are not.     

Missed Opportunities and New Risks: Penal Policy in England and Wales in the Past Twenty‐Five Years

This paper discusses trends in criminal justice and penal policy over the past twenty‐five years. This period has been characterised as a time of penal populism, which originated in the failure of the 1991 Criminal Justice Act, and the competition between the main political parties to be ‘tough on crime’. However, this is not the only trend to be found in penal policy. There has continued to be a strong undertow of support for rehabilitation and community penalties, including restorative justice. There has been pressure from the left as much as the right to take domestic violence, sexual offences against women and children, and hate crimes more seriously. There have been pressures to meet performance targets—which gradually transformed into calls to build the legitimacy of the justice system. Finally, there have been pressures to privatise criminal justice agencies. These various impulses have sometimes amplified and sometimes counteracted the pressures towards tough penal policy. If the period of intense penal populism ran from 1993 to 2007, inertia in the system has ensured that there have been no significant attempts to row back from tough policies, and to reassert the values of penal parsimony. Given that money has been tight since 2007 and crime has continued to fall, this must amount to a lost opportunity of significant proportions.     

Give them toys? Military allocations and regime stability in transitional democracies

In contrast to the conventional wisdom that democratization reduces coups, 46% of coups targeted democracies from 2000–2009, twice the rate seen in the prior half-century. Efforts to explain coups have arrived at wildly varied conclusions regarding the vulnerability of democracies. We argue that this is attributable to regime type acting as a conditional influence. We theorize that democratization incentivizes old elites to veto the process, and these vetoes are more likely to occur when the new regime cannot credibly commit to the military’s corporate interests. Using cross-national data for 172 states for the years 1952–2009, we find that though young democracies are more vulnerable to coups than either civilian authoritarian regimes or older democracies, this vulnerability is mitigated when military expenditures are near or above the sample mean. We also find that commonly argued determinants of coups appear to be driven by their influence in democracies, suggesting the need for scholars to revisit commonly held assumptions regarding autocratic survival.
