Analytical studies on some nitrogenous hallucinogens

Detection and identification of six members of the nitrogenous hallucinogens (glycolates, benzilates and phenyl acetamides) using thin-layer and gas-liquid chromatography and mass spectrometry were attempted. The methods used are sensitive, valuable and applicable in routine forensic analyses.     

Police supervision on the street: An analysis of supervisor/officer interaction during the shift

This article examines a major assumption of street supervisors in police agencies—that control of police officer behavior is dependent on strict hierarchical organization. The intellectual roots of this assumption are examined, and an emerging perspective developed from direct observation of patrol operations is presented. The research questions are addresses with data that were collected from observations of patrol activities in 60 residential neighborhoods in 24 agencies. The analysis, which is referenced to officers' shifts of duty, shows that the effect of supervision is in the direction posited by the authors of traditional police administration texts, but the magnitude of the effect is not overly strong. The findings are used to inform the evaluation of a common policy option directed at improving officer performance through supervision.
