On the accuracy of regulatory cost estimates

This study compares ex ante estimates of the direct costs of individual regulations to ex post assessments of the same regulations. For total costs the results support conventional wisdom, namely that the costs of regulations tend to be overestimated. This is true for 14 of the 28 rules in the data set discussed, while for only 3 rules were the ex ante estimates too low. For unit costs, however, the story is quite different. At least for EPA and OSHA rules, unit cost estimates are often accurate, and even when they are not, overestimation of abatement costs occurs about as often as underestimation. In contrast, for those rules that use economic incentives, unit costs are consistently overestimated. The difference between the total‐cost and the unit‐cost results is caused by frequent errors in estimates of the effects of individual rules, which suggests, in turn, that the rule's benefits may also be overestimated. The quantity errors are driven both by difficulties in determining the baseline and by incomplete compliance. In cases of unit‐cost overestimation, unanticipated technological innovation appears to be an important factor — especially for economic incentive rules, although procedural and methodological explanations may also apply. © 2000 by the Association for Public Policy and Management.     

Female prisoners' understanding of ‘bullying’ and their methods of coping: a multinational perspective

Abstract

Whilst prison bullying is a well-researched form of aggressive behaviour, recent studies have suggested that there may be discrepancy between how prisoners and researchers understand the term ‘bullying’. Interviews with 26 female prisoners were subject to constant comparison framework analysis. More than 150 themes were identified. These suggested that whilst there is overall agreement between prisoners and researchers as to what behaviours constitute bullying, a consensus does not exist within the prisoner population. Behaviours identified as bullying behaviours by prisoners are also reported as methods of coping. Cultural differences in behaviour and how these relate to perceptions of aggression were identified by the women prisoners. The findings of this study have implications for researching bullying in institutions such as prisons, and for managing and intervening with bullies in prisons.     

Designating the official opposition in a Westminster parliamentary system

Of all Westminster‐type representative assemblies, Canada's presents an unusually high number of cases where parties rank equal in second place, disputing the role of official opposition, both in the aftermath of an election or during a parliamentary session when party fortunes change. Although exceptional, the phenomenon is not at all uncommon; however, the uncertainty that characterises each of its occurrences indicates that no general rule has ever been drawn from doctrine or jurisprudence, as attested by the latest (1999) decision rendered by Speaker Scott in Nova Scotia. Thus, speculation persists whenever the situation presents itself. This paper attempts some rulings based on the distinction of context proper to 12 historical cases studied. It may help remove the uncertainty that plagues democratic systems in Canada as well as in any other Westminster‐type legislatures around the world.     

A new type of shotgun ammunition produces unique wound characteristics

The Tucson Police Department, Tucson, AZ, has begun using the Polyshok Impact Reactive Projectile (IRP), a new type of shotgun ammunition that includes a lead bead core that travels within single, plastic-encased projectile. On impact, the core is released to distribute over a small area, thereby disintegrating on impact to reduce the likelihood of exit or collateral damage on missed shots. After a brief review of shotgun slug ballistics and wound characteristics and a discussion of the mechanism of the Polyshok IRP, we report the first death in the United States from this ammunition. Findings included a single entrance wound with plastic ammunition components and small lead particles recovered from the body, the combination of which normally would suggest a close-range shooting with birdshot. However, the characteristics of this ammunition create different patterns than are found with slugs or shot, so that a medical examiner unfamiliar with the Polyshok IRP could draw inaccurate conclusions about ammunition and range of fire. Because the single projectile fired from this ammunition is composed of both plastic and lead, plastic components are likely to be found within the wound at any range of fire, unlike traditional shot or slug ammunition. Also, the small size of lead particles found spread through the wound cavity would ordinarily suggest a small-size shot, whereas the external appearance of the wound (a single entrance with no dispersion of shot) and the pattern of tissue destruction are more consistent with the patterns of injury associated with shotgun slugs.     

The role of community in facilitating service utilization

Guided by an integrated theory of parent participation, this study examines the role community characteristics play in influencing a parent's decision to use voluntary child abuse prevention programs. Multiple regression techniques were used to determine if different community characteristics, such as neighborhood distress and the community's ratio of caregivers to those in need of care, predict service utilization levels in a widely available home visiting program. Our findings suggest that certain community characteristics are significant predictors of the extent to which families utilize voluntary family supports over and above the proportion of variance explained by personal characteristics and program experiences. Contrary to our initial assumptions, however, new parents living in the most disorganized communities received more home visits than program participants living in more organized communities. The article concludes with recommendations on how community capacity building might be used to improve participant retention.
