Sharp force trauma analysis without animal bones: A proposal for sustainable and ethical bone proxies

Journal of Forensic Sciences, Volume 71, Issue 5, Page 2334-2344, September 2026.
Abstract Sharp force trauma has been the leading cause of homicide in England and Wales for more than a decade. Experimental research on sharp force trauma frequently relies on animal bone as a substitute for human remains, yet their ethical acceptability and comparability to human bone remain contested.

Between Hedging and Bandwagoning: E3 and Iran's Nuclear Program From the JCPOA to the 2026 “Ramadan War”

Global Policy, Volume 17, Issue 4, Page 658-669, September 2026.
ABSTRACT This article examines the evolution of the European Troika's narratives on Iran's nuclear program, from the aftermath of the JCPOA to the 2026 “Ramadan War.” Drawing on an analysis of 55 official statements by E3 leaders and diplomats, the study traces how the E3 shifted between a posture of normative hedging and one of bandwagoning.
