This article offers insights into the complexity of assessing the performance of public networks. We have identified three so-called exogenous factors: form of the network, type of inception—whether the network was initially formed as voluntary or mandated—and developmental stage of the network. We argue that where a network stands on each of these factors will determine the appropriateness of specific criteria for assessing the performance of the network.  相似文献

Many public agencies now face dual pressures to meet external accountability demands on one hand, and improve their internal performance on the other. This begs the question whether the demands that are made on public agencies to externally report on their performance have a limited or wide ranging impact on the utilization of performance indicators (PIs) for internal improvements. This article addresses this question via a small group of public agencies and public accountability authorities in Australia. It also examines the main factors that affect the use of PIs for decision making. The evidence suggests that the agencies use PIs more for meeting external reporting requirements than for achieving internal improvements. Various constraints on the use of PIs were identified, mainly technical problems, and to a lesser extent, political and organizational issues.  相似文献

We investigate links between ecological changes and changes in violence in Baltimore neighborhoods in the 1970's The two most salient ecological changes during the decade were (1) the emergence of a large number of gentrifying neighborhoods and (2) the further absorption of several older, minority neighborhoods into an “underclass” status Relative deprivation and social disorganization each predict increasing violence in gentrifying and emerging underclass neighborhoods. But, relative deprivation theory highlights the role of changes in economic status, whereas social disorganization highlights the role of changes in stability or family status. We further suggest that connections between ecological change and changes in disorder are contingent not only on historical context, but also on overall neighborhood structure at the beginning of the period. We hypothesize: (a) neighborhoods becoming more solidly “underclass” will experience increasing violence as status and stability decline and (b) emerging gentrifying neighborhoods will experience increasing violence as status and stability increase. Controlling for spatial autocorrelation, results support these hypotheses In emerging underclass neighborhoods status changes are most clearly linked to violence changes, whereas in gentrifying neighborhoods violence shifts are most closely tied to changing stability.  相似文献

This paper challenges the popular claim that police labor shortages existed in large American cities during the late 1960s and early 1970s. Empirical tests of a police salary determination model reveal that police managers and public officials possess only limited direct control over police wges. Hence, manipulation of police manpower utilization practices (and, more basically, labor supply to police departments) is the principal way of overcoming “labor shortages.” In recent years, this has included substitution of clerical for sworn personnel, elimination of non-job-related entry requirements, and expansion of auxilhry police forces.  相似文献

Policing tactics that are proactive, focused on small places or groups of people in small places, and tailor specific solutions to problems using careful analysis of local conditions seem to be effective at reducing violent crime. But which tactics are most effective when applied at hot spots remains unknown. This article documents the design and implementation of a randomized controlled field experiment to test three policing tactics applied to small, high‐crime places: 1) foot patrol, 2) problem‐oriented policing, and 3) offender‐focused policing. A total of 81 experimental places were identified from the highest violent crime areas in Philadelphia (27 areas were judged amenable to each policing tactic). Within each group of 27 areas, 20 places were randomly assigned to receive treatment and 7 places acted as controls. Offender‐focused sites experienced a 42 percent reduction in all violent crime and a 50 percent reduction in violent felonies compared with their control places. Problem‐oriented policing and foot patrol did not significantly reduce violent crime or violent felonies. Potential explanations of these findings are discussed in the contexts of dosage, implementation, and hot spot stability over time.  相似文献

Recent work (Cook and Ludwig, 2003) has linked local firearm density to increased burglary victimization risk. The current work investigates within‐household gun density or household firearm collection size. Previous work has suggested two subcultures of gun owners: protection‐minded and sport‐ or hunting‐minded. It also has identified gender gaps in reporting any household guns and in the number reported. None of the earlier work, however, has controlled for selection into gun‐owning household status. This limitation raises potential questions about earlier findings. The current research controls for selection. If the two subcultures thesis is correct, protection‐minded owners should report smaller household firearm collections. The expected impact is observed in one national survey and is partially replicated in a second. Gender gaps seemed more independent than previously suggested. This study is the first to provide evidence of two partially overlapping subcultures of gun owners even after controlling for selection into gun‐owning household status. Practical implications for burglary risk may exist.  相似文献
