The application, called P3i, is designed for use by law enforcement officers. P3i pushes the location data to officers’ smartphones, tablets, and MDT (mobile display terminal)/laptops. A randomized evaluation was conducted with the Lincoln (Nebraska) Police Department (LPD). Officers (N = 90) were randomly assigned to one of five GPS-enabled devices or a no-P3i, control condition. Over a six-month period, 75 treatment officers were compared to the 15 control officers on a variety of productivity measures as well as to officers’ prior year’s performance. Measures included citation arrests, warrant arrests, and information reports. We also collected self-report data from surveys asking officers about the duration, frequency, and intensity of their use of the technology. Analyses provide some evidence that officers who used the P3i application on GPS-enabled devices were more productive than controls and more productive than they had been during the prior year. Follow-up analyses suggested a variety of individual difference factors (e.g., high performance officers in 2011, low performance officers in 2010, males) also were correlated with increases in productivity. In focus group discussions with a subset of the officers in the study, the officers expressed great enthusiasm for the P3i application and their use of new mobile technologies in general. The officers had many suggestions for improvements and provided insights into how they specifically used their devices and P3i. A cost-benefit analysis suggested that implementation of the device results in a savings of around800 per officer, assuming a five-year device life and 7% interest rate. Additional assumptions considering different economic and technical scenarios were also developed and reported, but the results remained basically positive except for iPads, only have positive net benefits when there are no usage costs, while other devices have positive net benefits in almost all cases. In order to better understand officer adoption of P3i as well as their use of smartphones and tablets for work purposes, the project also examined what might account for the use of technology. Consistent with other studies, we found performance expectancy, a belief that the application would aid the participant in the performance of his or her duties, had the primary, significant effect on P3i usage. Thus, this study supports the position that if technology is made available, and officers have a reasonable expectation that it will help them in their work, they will utilize the technology. Further, if that technology actually can help them in their efforts, it is likely that the increase in productivity can be measured and captured. Our project also shows, however, that it may be difficult to find sensitive measures that will capture increases in productivity. One problem that can be anticipated is that outcomes are multi-determined, and thus it can be difficult to find measures that will be sensitive to positive impacts because of the multiple causes for the effects in which we are interested.”  aINFORMAÇÃO GEOREFERENCIADA9347423  aSISTEMA DE INFORMAÇÃO GEOGRÁFICA9344179  aTECNOLOGIA9234237  aESTUDO DE CASOS9322367  aEQUIPAMENTO POLICIAL9329370  aESTADOS UNIDOS9334103  aA RANDOMIZED-TRIAL EVALUATION OF A LAW ENFORCEMENT APPLICATION FOR SMARTPHONES AND LAPTOPS THAT USES GIS AND LOCATION-BASED SERVICES’ TO PINPOINT PERSONS-OF-INTEREST9358025  xOferta  104PJCD_258_00000000000000052022-06-066PJCD2589426227aPJcPJfPJ1CD258_65kPJCD258n2022-06-06o0rMOxOferta
