Thermal persistence and physicochemical modification of inorganic gunshot residue (IGSR)

Journal of Forensic Sciences, EarlyView.
Abstract In the medicolegal context, GSR analysis plays a key role in clarifying the dynamics of firearm‐related deaths, including lesion identification and firing distance determination. However, postmortem alterations of the body, such as thermal exposure, may influence the analysis of lesions and complicate interpretation.

Credibility–Constraint Decoupling and South Korea's Nuclear Option: Explaining Salience and Policy Conversion

Pacific Focus, EarlyView.
ABSTRACT South Korea presents a puzzle for threat‐centered accounts of allied nuclear politics. Why did South Korea advance into covert state‐directed exploration of a nuclear weapons option before North Korea possessed nuclear weapons, yet refrain from renewed state‐directed pursuit after North Korea built a substantial nuclear arsenal and posed a ...
