Phosphoglucomutase (PGM) grouping of bloodstains on silver.

This paper describes a case involving alteration of phosphoglucomutase (PGM) isoenzyme patterns in bloodstains present on silver. The effect could be produced by treating blood samples with silver nitrate solution.     

Why Not Invade North Korea? Threats, Language Games, and U.S. Foreign Policy

International relations theory has difficulty explaining how similar policies produce different outcomes. Iraq and North Korea have been identified as members of the "axis of evil" with weapons of mass destruction programs that threaten the United States. Yet in late 2002, the United States prepared to attack Iraq whereas it chose to negotiate with North Korea, even after North Korea admitted to a secret nuclear program in direct violation of its 1994 agreement with the United States. Moreover, a direct comparison with Iraq shows North Korea to possess the greater material capability to threaten the United States. I argue that a language-based constructivist approach can explain these differences in U.S. foreign policy where other theoretical approaches cannot. By examining the U.S. entanglement in intersected language games—the implementation of the 1994 Agreed Framework with North Korea and the enforcement of United Nations Resolutions in Iraq—it becomes possible to show how the United States could construct North Korea's nuclear program as a manageable threat that could be dealt with diplomatically.     

Is delusional ideation a critical link in the nexus between personality disorder and violent offending?

Evidence suggests that consideration of personality disorder (PD) severity, incorporating both externalising and internalising features of PD, might help to clarify the PD – violence relationship; moreover, that separate developmental pathways might link externalising and internalising personality pathology with criminal violence. This study of 96 forensic patients with confirmed PD and a history of violent offending addressed the question of whether delusional ideation, measured by the Peters Delusions Inventory, might play a significant role in the link between severe PD and criminal violence. Severe PD, defined by summing scores across DSM-IV PD criteria, was significantly associated with delusional thinking, with violence, and with high levels of both externalising and internalising personality features. Delusional thinking was associated with violence via internalising but not externalising PD features, suggesting that the link between severe PD and violence may be partly mediated by delusional thinking.
