Does a Place of Last Drink (POLD) Initiative Affect Alcohol Serving Staff Attitudes and Perceptions Related to Overservice of Alcohol?

Background: One enforcement strategy used to address illegal sales of alcohol to intoxicated patrons (i.e., overservice) is Place of Last Drink (POLD). When law enforcement responds to an alcohol-related incident, they ask persons involved in the incident where they had their last drink; POLD data can then be used to track patterns of overservice.Methods: We evaluated potential effects of a POLD initiative in one state (USA) on the attitudes and perceptions of serving staff (i.e., bartenders and servers) about their experiences in refusing sales to intoxicated customers. We conducted interviews with 44 serving staff across 24 communities (14 communities that participated in the POLD initiative and 10 comparison communities). We analyzed the interview transcripts using a qualitative matrix to identify major themes.Results: We found few differences across the two study conditions, with interview participants having no apparent awareness of POLD and many stating that overservice occurs frequently without law enforcement getting involved. One difference we identified was serving staff from communities in the POLD initiative reporting generally positive experiences with their managers when refusing sales to intoxicated patrons, whereas serving staff in comparison communities more commonly saying they were overruled by their managers. It is possible that these differences are the result of the POLD initiative; however, more research is needed.Conclusions: In general, serving staff across communities share many similar perceptions and attitudes around overservice. These findings can inform future implementation of POLD and other strategies to reduce overservice of alcohol.

Redundancy gain in visual search of simulated X-ray images.

Cancer diagnosis frequently relies on the interpretation of medical images such as chest X-rays and mammography. This process is error prone; misdiagnoses can reach a rate of 15% or higher. Of particular interest are false negatives-tumors that are present but missed. Previous research has identified several perceptual and attentional problems underlying inaccurate perception of these images. But how might these problems be reduced? The psychological literature has shown that presenting multiple, duplicate images can improve performance. Here we explored whether redundant image presentation can improve target detection in simulated X-ray images, by presenting four identical or similar images concurrently. Displays with redundant images, including duplicates of the same image, showed reduced false-negative rates, compared with displays with a single image. This effect held both when the target's prevalence rate was high and when it was low. Eye tracking showed that fixating on two or more images in the redundant condition speeded target detection and prolonged search, and that the latter effect was the key to reducing false negatives. The redundancy gain may result from both perceptual enhancement and an increase in the search quitting threshold.
