1H nuclear magnetic resonance of heroin's D ring

The 1H nuclear magnetic resonance (NMR) chemical shifts and coupling constants of heroin's D ring H-15 alpha, H-15 beta, and H-16 alpha, and H-16 beta are presented. These assignments were accessible through the introduction of a double bond (delta 15,16) in heroin. The resulting compound, delta 15,16 didehydroheroin, was subjected to deuterium exchange or stereoselective reduction or both. Reduced products d1-16 alpha heroin d2-15 alpha, 15 beta-heroin, and d3-15 alpha, 15 beta, 16 alpha-heroin are presented. Heroin with deuterated acetyls is also presented for 1H NMR spectral clarity in the D ring area.     

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.     

Evidence for the role of the justice motive in status generalization processes

Status generalization refers to the capacity of status characteristics, such as race, gender, or occupation, to become the basis of social inequality even when such characteristics are not directly relevant to the immediate social interaction. For instance, individuals with positively valued status characteristics are more likely to assume positions of power and prestige than those of lower standing. To date, status generalization has been assumed to arise from stereotyped beliefs that associate positive standing on a status characteristic with positively valued personal attributes. Findings from two studies indicate that the capacity for status characteristics to produce power and prestige orders may also depend on people's need to believe in a just world. In the first study, participants were fortuitously granted a position of either superior or equal power and prestige to another person. Consistent with just world predictions, participants portrayed themselves more positively relative to the other on assessments of personal attributes when they occupied a superior position than when they occupied a position of equal power and prestige. Results from a second study showed that the tendency to link personal attributes with power and prestige standing was strongest for participants who scored high on the Just World Scale. Thus, just world beliefs appear to play a role in status generalization processes.
