Rapid Analysis Of Forensic-Related Samples Using Two Ambient Ionization Techniques Coupled To High-Resolution Mass Spectrometers, Eshwar Jagerdeo, Amanda Wriston

United States Department of Justice: Publications and Materials

RATIONALE: This paper highlights the versatility of interfacing two ambient ionization techniques, Laser Diode Thermal Desorption (LDTD) and Atmospheric Solids Analysis Probe (ASAP), to high-resolution mass spectrometers and demonstrate the method’s capability to rapidly generate high-quality data from multiple sample types with minimal, if any, sample preparation.

METHODS: For ASAP-MS analysis of solid and liquid samples, the material was transferred to a capillary surface before being introduced into the mass spectrometer. For LDTD-MS analysis, samples were solvent extracted, spotted in a 96-well plate, and the solvent was evaporated before being introduced into the mass spectrometer. All analyses were performed using …

The Criminalization Of Walking, Michael Lewyn

Scholarly Works

The simple act of walking is sometimes criminalized in the United States. Anti-jaywalking statutes and ordinances—originally motivated by auto-industry lobbyists in the 1920s—call for fines and, sometimes, imprisonment for crossing the street. Additionally, some localities have interpreted statutes against “child neglect” to encompass a parent’s decision to let their kid walk outside alone. The result of this criminalization? Such policies have reduced pedestrian liberty, increased automobile traffic and pollution, and created a disincentive for physical activity in the midst of an obesity and diabetes epidemic. In addition to discussing these effects, this Article argues that the purported safety benefits of …
