Article Synopsis
  • Finding an unfamiliar person in crowds is challenging for police and security, with low accuracy reported in identifying suspects or missing individuals.
  • Two visual-search experiments were conducted to assess whether showing participants four images of a target person improves accuracy compared to just one image, with varied video angles simulating CCTV and body camera footage.
  • The results indicated that presenting four images significantly improved identification accuracy in one experiment, and participants tended to be more conservative in claiming a person wasn't present when only one image was available, supporting the use of multiple images in visual searches.

Purpose: The aim of this study is to examine small area variation in crime trajectories during the COVID-19 pandemic in England and Wales. While we know how police-recorded crime responded to lockdown policies at the 'macro' level, less is known about the extent to which these trends were experienced uniformly at localized spatial scales.

Methods: Longitudinal k-means clustering is used to unpick local area variation in police notifiable offences across England and Wales.

An entrustable professional activity (EPA) model was used to assess the anesthesia and surgery competence of year 4 students during elective neutering procedures over 3 academic years (cohort A, cohort B, and cohort C). Two competence thresholds were defined by an expert panel, the minimum acceptable standard (MAS) and the standard expected at the start of final-year rotations (SFR). The assessment scheme performed as expected, and the median level of supervision achieved by students either matched or exceeded the SFR for all EPAs except one, which matched the MAS.
