Reduction of police vehicle accidents through mechaniically aided supervision

Tachograph recorders were installed in 224 vehicles of a metropolitan police department to monitor vehicle operation in an attempt to reduce the rate of accidents. Police sergeants reviewed each tachograph chart and provided feedback to officers regarding their driving performance. Reliability checks and additional feedback procedures were implemented so that upper level supervisors monitored and controlled the performance of field sergeants. The tachograph intervention and components of the feedback system nearly eliminated personal injury accidents and sharply reduced accidents caused by officer negligence. A cost-benefit analysis revealed that the savings in vehicle repair and injury claims outweighed the equipment and operating costs.     

LARGE-SCALE REDUCTIONS IN SPEEDING AND ACCIDENTS IN CANADA AND ISRAEL: A BEHAVIORAL ECOLOGICAL PERSPECTIVE

We assessed the effects of posted feedback and warning ticket programs on speeding and accidents in two cities. In Experiment 1, speeding feedback signs were effective even when 10 were used in Dartmouth, Nova Scotia, and reductions in speeding were associated with reductions in accidents. The effectiveness of the signs was correlated with the number of intersections and residences within 0.5 km beyond them, and the signs had no effect on untreated streets. In Experiment 2, posted feedback and a warning program reduced speeding and accidents on 14 streets in Haifa, Israel.     

Police responses to diversity: A social representational study of rural British policing in a changing representational context

In the first decade of the 21st century, British policing faced two new challenges in how it responded to social diversity: As well as instituting reforms in response to a highly publicized report describing the British police as ‘institutionally racist’ (Macpherson, 1999 ), they faced challenges associated with rapid increases in numbers of immigrants into the UK. Studying social representations at such times of change allows access into processes, themes and value systems that may otherwise remain hidden. This paper uses social representations theory to explore interview accounts provided by regular police officers of interactions with members of minority groups. Empirically, we focus on an area of diversity policing that has received relatively little previous attention: Police work in a rural context that has recently played host to large numbers of migrant workers. Our analysis shows that interviews operate as a site of resistance in which respondents attempt to rework hegemonic representations of the police as prejudiced and to re‐present themselves and their work as able to respond appropriately to diversity. Fairness as a defining characteristic of good police practice is a central representational theme that links identity construction processes to police work with minority groups. Recent immigrant groups are represented as both needing and deserving help to assimilate into British culture: Their lack of acculturation and language difficulties provide additional challenges to police work and to how this is judged as ‘fair’. We discuss the broader origins and implications of police officers' understandings of fairness and the use of social representations theory to study representational fields within organizational settings.

Misconduct in science and the german law

In the past, only norms and rules developed for other types of illegal activities could be applied to misconduct in science in Germany. But only particularly blatant cases of misconduct can be dealt with efficiently in this way. Nowadays, a couple of very important funding agencies and research institutions have enacted special procedures that apply in cases of suspected scientific misconduct. A strongly decentralised system of dealing with misconduct in science is being established in Germany. An earlier version of this paper was presented at a symposium, Scientific Misconduct. An International Perspective, organised by The Medical University of Warsaw, 16 November, 1998.     

On Ultrafilter Logic and Special Functions

Logics for generally were introduced for handling assertions with vague notions,such as generally, most, several, etc., by generalized quantifiers, ultrafilter logic being an interesting case. Here, we show that ultrafilter logic can be faithfully embedded into a first-order theory of certain functions, called coherent. We also use generic functions (akin to Skolem functions) to enable elimination of the generalized quantifier. These devices permit using methods for classical first-order logic to reason about consequence in ultrafilter logic.Presented by André Fuhrmann     

Pyramidal training for families of children with problem behavior

The pyramidal training model was extended to multiple family members of children with behavior disorders. Three primary caregivers were taught to implement individualized treatments for problem behavior. They were then taught how to use various instructional strategies (e.g., prompting, feedback) to teach 2 other family members to implement the treatment. Results showed that pyramidal training was effective in increasing caregiver implementation of treatments across three families.     

STIMULUS FADING AS TREATMENT FOR OBSCENITY IN A BRAIN-INJURED ADULT

Obscene verbalizations of a person with traumatic brain injury were treated using stimulus fading as the singular form of intervention. Results of a functional assessment revealed that obscenity was maintained by negative reinforcement. Stimulus fading (initial elimination of instructional demands followed by their gradual reintroduction) produced immediate and substantial reductions in obscenity that were maintained as the frequency of demands increased to baseline levels. Potential applications of the use of antecedent treatment strategies are discussed.     

SELECTING A COST-EFFECTIVE SCREENING MEASURE FOR THE ASSESSMENT OF PRESCHOOL SOCIAL WITHDRAWAL

The utility of teacher judgment (rankings, ratings) and peer judgment (sociometric ratings) were studied as screening variables for preschool social withdrawal/responsiveness. Observational measures of preschoolers' interaction were used as the validation criterion based upon theoretical, empirical, and practical considerations related to development of a multipurpose behavioral assessment system. Results indicated that teacher rankings of students' verbal interaction frequencies (1) were most highly correlated to interaction rate in two preschool settings, (2) had test-retest reliability consistently above Rho = .80, and (3) were useful in that 77% of teachers using this procedure could identify their least socially responsive student within five rankings. The peer nomination sociometric rating was the least reliable measure at retest (Rho = .35) and showed consistently the lowest correlation with observational indices of interaction partner preferences, e.g., reciprocal rate (Rho = .29 to .39). The tendency for relationships among screening measures and the criterion to increase at retest suggested a training effect on screening accuracy. The use of teacher rankings in combination with observational measures to confirm selection accuracy and for monitoring treatment progress is discussed as a cost-effective behavioral assessment procedure for preschool social withdrawal/responsiveness.     

A method for combining occurrence and nonoccurrence interobserver agreement scores

Various statistics have been proposed as standard methods for calculating and reporting interobserver agreement scores. The advantages and disadvantages of each have been discussed in this journal recently but without resolution. A formula is presented that combines separate measures of occurrence and nonoccurrence percentages of agreement, with weight assigned to each measure, varying according to the observed rate of behavior. This formula, which is a modification of a formula proposed by Clement (1976), appears to reduce distortions due to "chance" agreement encountered with very high or low observed rates of behavior while maintaining the mathematical and conceptual simplicity of the conventional method for calculating occurrence and nonoccurrence agreement.     

Patrol evaluation research: a multiple-baseline analysis of saturation police patrolling during day and night hours

The effects of a carefully monitored and increased police patrol on the report of crime were examined in four patrol zones. Overall patrol movement was increased to four times normal levels and slow patrol movement (under 20 mph) to around 30 times normal levels for 10 days. The patrol was active in two zones between 9:00 a.m. and 5:00 p.m. and in the other two zones between 7:00 p.m. and 3:00 a.m. A multiple-baseline design and time-series statistical analyses showed statistically reliable changes in reported levels of Part I crime (such as robbery, burglary, and aggravated assault) during both night patrols, but not in the day patrols. In both night-patrol zones, there were also reliable increases from saturation patrol to postsaturation patrol in report of Part I crime after the night patrol was terminated. Neither of the day patrols showed significant crime report changes on termination. Despite statistically reliable decreases in report of crime during nighttime hours, the value of saturation patrolling as a crime-prevention technique was questioned on cost/benefit grounds.
