Psychometric properties of the Barratt Impulsiveness Scale version 11 among a Portuguese sample of incarcerated juvenile offenders

The aim of the present study was to examine the psychometric properties of the Barratt Impulsiveness Scale version 11 (BIS-11) among a forensic sample of incarcerated male juvenile offenders (N?=?221). Principal Component Analysis with Promax rotation revealed the expected 6-factor structure, but Confirmatory Factor Analysis of the 6-factor first-order and the 3-factor second-order factorial structures did not present sufficiently good fits. Despite that, the Portuguese adaptation of the BIS-11 demonstrated generally acceptable psychometric properties in terms of internal consistency, mean inter-item correlation, convergent validity, discriminant validity, and concurrent validity that justifies its use among the youth forensic population. Statistically significant associations were found with age of crime onset, conduct disorder, crime seriousness, alcohol use and drug use.     

Shift patterns and hardiness: Police use of lethal force during simulated incidents

In the present experiment, utilizing the Film Fire' shooting simulation system, the effects of shift patterns and hardiness on police officers' judgments (decisions to (i) shoot at a suspect and (ii) taking cover during the confrontation) were examined. Sixty-one Authorised Firearms Officers were briefed on two “incidents” they would be asked to attend. The experiment took place at three different times, each time one hour before completion of the shift: at 1 p.m. (early day shift), 9 p.m. (late day shift), or 5 a.m. (night shift). In one incident the officer would be justified in shooting the suspect, whereas in the other incident it would be difficult for the officer to justify having shot the suspect. Because in both incidents the suspects were threatening the police officer, taking cover during both incidents would be desirable. Results revealed that most erroneous decisions occurred during the early shift, and that officers low in hardiness made more incorrect judgments than officers high in hardiness. Implications of the findings are discussed. Authors' Note: This study has been sponsored by the Economic and Social Research Council (ESRC), studentship award given to the first author.     

Monitoring Single-Source Revenue Funds throughout the Budgeting Process

Unexpected revenue shortfalls that occur during budget execution create serious problems for public agencies and programs. This is especially true for agencies and programs that rely upon a single source of revenue. This article implements a revenue monitoring process that combines ideas from statistical process control and exploratory data analysis into a spreadsheet environment. The methodology builds on principles used to monitor manufacturing processes. This simple application helps public managers detect revenue surpluses and deficits early enough in the budget execution process to take corrective action. The methodology also adapts to the data problems and avoids many of the pitfalls that arise when using "real world" budget data. An example of the benefits of this methodology is offered using an example of a state agency funded by a single revenue source.
