Blunt force cranial trauma in the Cambodian killing fields

In this paper we present a unique pattern of blunt force cranial trauma that was observed in 10 of a sample of 85 crania from a Cambodian skeletal collection comprised of Khmer Rouge victims. Initial examination of the trauma, which presents as substantial damage to the occipital with fractures extending to the cranial base, suggested the pattern was classifiable as a basilar or ring fracture. However, further investigation, including trauma analysis and historical research, revealed that this fracture type is distinctive from basilar and ring fractures. Historical data indicate that a particular execution method was the likely source of the trauma. Recognition of this trauma pattern is significant because it exemplifies the distinct fracture configuration resulting from an apparently categorical and methodical execution technique. Identification of this fracture type could potentially assist forensic investigators in the recognition of specific methods of murder or execution.     

Political Liberalism, Marriage and the Family

Can and should political liberals recognize and otherwise support legal marriage as a matter of basic justice? In this article, we offer a general account of how political liberals should evaluate the issue of whether the legal recognition of marriage is a matter of basic justice. And, we develop and examine some public reason arguments that, given the fundamental interests of citizens, could justify various forms of legal marriage in some contexts. In particular, in certain conditions, the recognition of some form of legal marriage may be the best way to protect the fundamental interests of women as citizens in freely chosen associations. Or, it may be that, in certain conditions, to secure the social conditions necessary for gays, lesbians and bisexuals to be free and equal citizens, some form of legal marriage can or should be recognized.     

Light as an Analogy for Cognition in Buddhist Idealism (Vijñānavāda)

In Sect. 1 an argument for Yogācāra Buddhist Idealism, here understood as the view that everything in the universe is of the nature of consciousness / cognition, is laid out. The prior history of the argument is also recounted. In Sect. 2 the role played in this argument by light as an analogy for cognition is analyzed. Four separate aspects of the light analogy are discerned. In Sect. 3, I argue that although light is in some ways a helpful analogy for the Buddhist Idealist, in other ways it is thoroughly inappropriate. At the end of the article I ask whether the lack of fit between light and cognition is unavoidable, or whether the Buddhist Idealists could have chosen a better analogy.     

Ballistic impact of hollow-point ammunition on porcine bone

Identifying failure mechanisms in skeletal tissue allows a deeper understanding of the effects of specific projectile impacts on bone. While ballistic trauma in flat bones is largely researched, knowledge of how long bones react to gunshot impacts is limited in the literature. The impacts of deforming ammunition appear to produce higher levels of fragmentation; however, these have not been studied in depth. This study compares the damage to femora bone by HP 0.357 and 9 mm projectiles constructed with both full and semi-metal jackets. Impact experiments were undertaken on a single-stage light gas gun involving the use of a high-speed video camera and full reconstruction of the bones to ascertain fracture patterns occurring in the femora. Higher degrees of fragmentation are likened to the presence of semi-jacketed HP projectiles than jacketed HP projectiles. The observations of external facing beveled edges are believed to be associated with the increased separation of the jacket and lead core of projectiles. Additionally, experimentation has shown that the amount of kinetic energy lost postimpact is likely related to the presence or the absence of a metal jacket on an HP projectile. The observed data, therefore, suggest that the composition, rather than the configuration, of a projectile affects the type and extent of the damage.
