AbstractIn this study, we compare the rates of New Zealand (NZ) and England and Wales (EW) police shootings from 1970 to 2020. Taking this long view lessens the stochastic effect of shootings over shorter time periods and reveals that the frequency of police shootings has increased in both jurisdictions over this period, despite police not being routinely armed with firearms. In EW, police shootings have increased from an average of 1.4 persons shot per annum for the decade ending 1980 to 4.3 per annum for the decade ending 2020. Similarly, NZ has seen an increase of 0.3 persons shot per annum (decade ending 1980) to 3.7 per annum (decade ending 2020). When comparing the rate of persons shot per million population in the past two decades, NZ has doubled the rate of shootings from 0.360 per million (2001–10) to 0.783 per million (2011–20). Such an increase has not occurred in EW as the number of persons shot has decreased from 0.080 per million (2001–10) to 0.074 per million (2011–20). We highlight the time-series trajectories with trend breakpoints at points of known policy implementations.

In commercial market research, "pulsing" advertising is found to be more cost-effective than placing advertisements continuously. However, the benefits of pulsing policy in social marketing have rarely been tested. This study explores the lingering effect of tobacco control advertising. If the effects of tobacco control advertisements linger beyond the time they are on-air, this would provide a theoretical basis for using pulsing policy in tobacco control campaigns. This study analyzed responses from two independent samples of smokers and recent quitters, where respondents reported whether they were exposed to any tobacco control advertising in the last week. Sample 1 was cross-sectional ( n = 3,106), and Sample 2 followed a self-refreshed panel methodology where 846 participants were interviewed for up to 6 times (3,120 interviews). Both studies used the same survey instrument and were in field concurrently. Eighty percent of Sample 1 reported recent exposure to advertising. This was strikingly similar to the response from Sample 2 recorded at their first interview (81%). However, panel members' self-reported exposure to campaigns decreased at each subsequent interview (approximately a fortnight apart) and eventually reached 56% at the sixth interview. Building on the premises of priming theory, the first response from each Sample 2 respondent represented his or her intuitive thought—a result of the lingering effect of advertising. The drop in recall over time could be due to respondents self-correcting their responses after being primed in the previous surveys. Our findings suggest the effects of tobacco control campaigns linger and support the use of pulsing policy in tobacco control advertising.
