The relationship between education level and performance ratings of campus police officers

Data from 165 campus police officers at 16 campus police departments were used to investigate the relationship between educational level and performance of campus police officers. The results of the study indicated that education was significantly related to supervisor ratings of report writing proficiency (r=.29) and communication skills (r=20) but not discipline problems (r=−.01) or overall performance (r=.10). The relationship between education and report writing proficiency was moderated by years of police experience as education predicted performance in officers with five or more years experience but not those with less than five years experience.     

Exploratory trial of schema-focussed therapy in a forensic personality disordered population

The management of needs and risks in personality disordered offender populations has become a focus for health and criminal justice services in the UK. Recent studies demonstrate the effectiveness of schema focussed therapy (SFT) for patients with borderline personality disorder. This study was an exploratory trial of the feasibility of implementing SFT in a population of patients with personality disorder in a high secure hospital in England. Preliminary evaluations of the effects of SFT were conducted to investigate whether those receiving SFT demonstrated significant improvements on measures of anger, impulsiveness, schemata and interpersonal style. No significant effects were evident although there was a significant increase in defectiveness/shame schema in the SFT group. Lack of effectiveness of SFT is likely due to the preliminary nature of this study. Future trials of SFT need to ensure comprehensive therapist preparation, control of TAU, bigger samples, address attrition and provide more intensive therapy.     

Conclusions from the history of research into the effects of police force size on crime—1968 through 2013: a historical systematic review

Objectives

We describe and explain how the findings from nonexperimental studies of the relationship between police force size and crime have changed over time.

Methods

We conduct a systematic review of 62 studies and 229 findings of police force size and crime, from 1971 through 2013. Only studies of U.S. policing and containing standard errors of estimates were included. Using the robust variance estimation technique for meta-analysis, we show the history of study findings and effect sizes. We look at the influence of statistical methods and units of analysis, and time period of studies’ data, as well as variation in police force size over time.

Results

Findings vary considerably over time. However, compared to research standards and in comparison to effect sizes calculated for police practices in other meta-analyses, the overall effect size for police force size on crime is negative, small, and not statistically significant. Changes in research methods and units of analysis cannot account for fluctuations in findings. Finally, there is extremely little variation in police force size per capita over time, making it difficult to estimate the relationship with reliability.

Conclusions

This line of research has exhausted its utility. Changing policing strategy is likely to have a greater impact on crime than adding more police.
