The relationship between education, experience, and police performance

This study used data from 299 police officers from 12 municipal police departments across the state of Virginia to determine the relationship between education and police performance. Performance was measured by supervisor evaluations of each officer's overall performance, communication skills, public relations skills, report writing skills, response to new training, decision making ability, and commitment to the police department. Significant correlations were found between education and most measures of performance. Most importantly, the results show a significant correlation between overall performance and education (r=24, p.<001). The only variables not proving to be significantly related to education were objective measures of the volume of arrests, number of times the officer required discipline, and number of accidents. Interestingly, the benefits of a college education do not become apparent until police officers gain experience. In addition, police, officers with only a high school diploma decreased in overall performance after five years of experience.     

Marketization, Managers and Moral Strain: Chairmen, Directors and Public Service Ethos in the National Health Service

Survival of the public service ethos in Britain has been called into question following introduction of the 'new public management' and marketizing reforms in much of the public sector. This article examines how these developments have occurred in the NHS, using survey data to analyse NHS board members' substantive ethical values. Unexpectedly the results suggest that NHS board members with a predominantly NHS background appear less ethically conservative, more flexible and less risk–averse than those recruited from non–NHS backgrounds; and that as yet the NHS management 'culture' is not very homogenous in respect of 'business ethics'. The NHS reforms also appear to accentuate the tensions between transparent public accountability in NHS management and incentives not to publicize certain types of information. Recent codification of NHS 'business ethics' can be understood as an attempt to buttress the public service ethos against the increased moral strains of a quasi–market.     

Traffic accidents and drivers suspected for drug influence

All records from the Danish Medicolegal Council concerning drivers suspected for drug influences were examined for the 5 year period 1981-1985. 461 records were included, 62 women and 399 men. In 250 cases drugs from more than one of ten groups had been taken thus making 786 combinations of drug/driving. The major drug group was benzodiazepines, accounting for 65% of all drug intake. Opioids also contributed substantially, found in 38% of the cases. A traffic accident had occurred in 180 (39%) of the records. Drivers who had been taking antidepressives were involved in an accident in 67%, significantly above the mean. For benzodiazepines, the corresponding percentage was 43%, while for opioids it was only 23%, significantly below the mean. This striking difference has been demonstrated in most of the studies concerning drugs in traffic. It may support the hypothesis that opioids do not necessarily make driving dangerous, as do antidepressives, barbiturates and especially benzodiazepines.     

Bounding the number of contributors to mixed DNA stains

We derive a simple inequality for the probability of observing a given DNA profile when assuming a fixed number of unknown persons have contributed to the mixed stain. We then show how this inequality can be used to obtain an upper bound for the number of unknown contributors needed to be considered.
