Cluster hanging suicides in the young in South Australia

Retrospective review of hanging suicides in individuals aged ≤ 17 years was undertaken at Forensic Science South Australia, Australia, over two 5-year periods: 1995-1999 and 2005-2009. Seven cases of hanging suicides were identified from 1995 to 1999, with a further 14 cases from 2005 to 2009, an increase of 100% (p < 0.001). Hanging accounted for 33.3% of all suicides in this age group (7/21) from 1995 to 1999, compared with 93.3% of the total number of suicides (14/15) in the second 5-year period. In contrast, Australian national data from 1998 and 2008 showed a 30% decrease in hanging suicides in the young, from one case/100,000 population in 1998 to 0.7 in 2008. Cluster suicides occur in the young and are often initiated by direct communication. As it is possible that Internet-based social sites may facilitate this phenomenon, investigations should include an evaluation of the victim's Internet access given the potential risk of similar actions by peers.     

Lethal manifestations of systemic lupus erythematosus in a forensic context

Systemic lupus erythematosus is an autoimmune connective tissue disorder that affects multiple organs. While the clinical manifestations may vary in intensity over time and be associated with chronic disease, occasional cases occur where sudden and unexpected death has occurred. Cardiovascular disease is common, with accelerated atherosclerosis, intravascular thrombosis associated with antiphospholipid syndrome, and hypertensive cardiomegaly. Vasculitis with superimposed thrombosis may result in critical reduction in blood to vital organs, such as the heart and brain with infarction. Mesenteric ischemia may be caused by vasculitis, thrombosis, and accelerated atherosclerosis and may result in lethal intestinal infarction. Other diverse causes of sudden death include myocarditis, epilepsy, pulmonary hypertension, pulmonary thromboembolism, and sepsis. The autopsy evaluation of such cases requires careful examination of all organs with extensive histological sampling to include blood vessels, and microbiological sampling for bacteria, viruses, and fungi.     

Vitreous humor sodium levels in immersion deaths

To determine whether vitreous humor sodium levels might be of use in evaluating deaths associated with immersion, samples of vitreous humor were prospectively evaluated at autopsy over a 4-year period from 2006 to 2009. There were 19 cases of saltwater immersion (age range 9-76 years; mean age 44 years; M:F, 2.8:1) and 16 freshwater immersions (age range 2-81 years; mean age 27 years; M:F, 2.2:1). In the group of saltwater drownings, vitreous humor sodium levels were elevated, ranging from 145 to 184 mM (mean = 160.2 ± 9.9 mM), and in the cases of freshwater drowning, the levels were reduced, ranging from 73 to 148 mM (mean = 129.8 ± 17 mM; p < 0.0001). Alterations in electrolyte levels may have been because of hemoconcentration or dilution from electrolyte fluxes in the lungs, or from passive diffusion during immersion. This study has demonstrated that vitreous sodium level is an easily performed test that may be a useful adjunct to the investigation of possible immersion deaths.     

How Useful is Basal Renal Tubular Epithelial Cell Vacuolization as a Marker for Significant Hyperglycemia at Autopsy?

Basal vacuolization of renal tubular epithelial cells (so-called Armanni-Ebstein phenomenon) has been attributed to hyperglycemia causing accumulation of cytoplasmic glycogen. Review of 34 autopsy cases with significant hyperglycemia (vitreous glucose ≥ 15 mmol/L/270 mg/dL) was undertaken to determine whether there was any significant association between the degree of hyperglycemia and the severity of this morphological change (graded as 0, 1+, 2+, and 3+). No association was demonstrated. Review of the subgroup of 14 cases with terminal hyperglycemia without ketoacidosis was then undertaken to assess the effect of hyperglycemia in isolation on renal tubular epithelial cells. Vitreous glucose levels in these 14 cases ranged from 17 to 49.7 mmol/L (306-894.6 mg/dL) with a mean of 26.25 mmol/L (472.5 mg/dL) and β-hydroxybutyrate levels ranged from 0.02 to 2.55 mmol/L (0.36-45.9 mg/dL) with a mean 0.79 mmol/L (14.22 mg/dL). Not one of the latter cases displayed basal vacuolization. No relationship between basal vacuolization of renal tubular epithelial cells at autopsy and terminal hyperglycemia could, therefore, be demonstrated.     

The constitutional political economy of Gordon Tullock

This paper surveys Gordon Tullock’s contributions to constitutional political economy. His first major contribution was his joint project with James Buchanan on liberal constitutional design. The explicitly constitutional analysis of The Calculus was followed by a series of papers and books that focused on the use of resources in conflict, including Tullock’s contributions to the anarchy and rent-seeking literatures. Tullock also pioneered the rational choice-based analysis of dictatorships and the relative merits of alternative legal systems, topics that has been neglected until fairly recently by most scholars working in the CPE tradition.     

On the political economy and limits of crisis insurance: the case of the 2008–11 bailouts

The bailouts of 2008–10 are the most recent in a long series of insurance-like policies designed to limit the losses of those harmed by a crisis of some kind—but enacted after a crisis is under way. This paper analyzes the economics and politics of “crisis insurance” programs. The analysis helps explain why ex-post insurance is popular, why it tends to be undersupplied by private markets, and why governments may be better able to provide it. The analysis also points out that there are limits to what losses can be covered. The routine adoption of new programs to limit losses from crises tends to require greater expenditures through time because of moral hazard problems and the nature of crises. Eventually, this trend may produce “uninsurable” crises. The analysis of this paper suggests that such problems can be moderated, although not eliminated, through appropriate standing polices for ex-post funding of crisis insurance.     

Still three Wales? Social location and electoral behaviour in contemporary Wales

Wales provides a notable exception to the contemporary academic consensus that electoral behaviour is best studied via choice-based approaches. In Wales, the orthodoxy remains that of the Three-Wales Model, an approach formulated in the 1980s which saw voting behaviour as defined by class, language and national identity. This article submits the Three-Wales Model to detailed scrutiny for the first time. The model is argued to have been constructed on a very narrow theoretical basis, and on flawed measurements. Most importantly, however, the Three-Wales Model is shown to have little empirical leverage on voting behaviour in Wales – either for the period when it was formulated or for more recent elections. Factors associated with ‘valence politics’ theories are shown to provide far greater insight into voting behaviour in contemporary Wales.
