Evolution of the Psychological Autopsy: Fifty Years of Experience at the Los Angeles County Chief Medical Examiner‐Coroner's Office

The origin of the psychological autopsy was in the late 1950s and the result of a collaboration between the Los Angeles County Chief Medical Examiner‐Coroner's Office and the Los Angeles Suicide Prevention Center. It was conceptualized as a thorough retrospective analysis of the decedent's state of mind and intention at the time of death. It was used initially in “equivocal” deaths where the manner of death was possibly either suicide or accident. Later, it was used in cases where a party (primarily family members) protested the Medical Examiner‐Coroner's suicide determination. Over the past 25 years, the University of Southern California Institute of Psychiatry, Law, and Behavioral Science has served as the psychiatric/psychological consultants to the Coroner's Department. Research findings, the use of this approach in high‐profile cases, and the most recent manner in which the psychological autopsy is conducted are discussed.     

Trace analysis of urea nitrate by liquid chromatography-UV/fluorescence

In this paper we have adapted a technique, previously used to determine the presence of urea in aqueous samples of wine and urine, to detect trace levels of urea nitrate explosives. The procedure involves the reaction of the uronium ion (protonated urea) with a fluorophore, xanthydrol. By modification of the procedure to utilize non-aqueous reagents, in neutral conditions, it can be made specific to the presence of the urea nitrate ion pair. The procedure includes selective detection of derivatization products by UV and fluorescence following separation by High-Performance Liquid Chromatography (HPLC). Analytical method development included optimization of HPLC conditions (solvent, gradient), UV and fluorescence wavelengths, and derivatization parameters (xanthydrol amount, reaction times, temperature). The extraction of urea nitrate from surfaces was also investigated and optimized. For best quantification, it was shown that an internal standard was required; this resulted in a quantification limit around 0.17mM (21mg/L). The entire procedure could be performed in less than 30min per sample and potential interferences such as ammonium, nitrate, and urea did not produce a response under standard conditions.     

Reflections on the Spirit and Work of the U.S. Advisory Commission on Intergovernmental Relations

What did the U.S. Advisory Commission on Intergovernmental Relations (ACIR) accomplish before it was disbanded in 1996? Were its accomplishments sufficiently valuable to justify reestablishing the organization? This article reviews the commission’s origins, history, and accomplishments, and addresses future intergovernmental needs. The ACIR’s accomplishments were substantial, but are largely unavailable today. Lessons learned from the ACIR suggest the need to (1) recreate a network of intergovernmental advocates within the legislative and executive branches of the federal government; (2) restart the information flows and high‐level federal, state, and local policy dialogues that withered after the ACIR’s demise; (3) strengthen boundary‐crossing institutions capable of addressing metropolitan and multistate problems; and (4) develop new opportunities to achieve public policy outcomes that can be attained only by the cumulative efforts of federal, state, and local governments working together—often with private parties as well.
