Ballistic imaging databases allow law enforcement to link recovered cartridge cases to other crime scenes and to firearms. The success of these databases has led many to propose that all firearms in circulation be entered into a reference ballistic image database (RBID). To assess the performance of an RBID, we fired 4200 cartridge cases from 600 9 mm Para Sig Sauer model P226 series pistols. Each pistol fired two Remington cartridges, one of which was imaged in the RBID, and five additional cartridges, consisting of Federal, Speer, Winchester, Wolf, and CCI brands. Randomly selected samples from the second series of Remington cartridge cases and from the five additional brands were then correlated against the RBID. Of the 32 cartridges of the same make correlated against the RBID, 72% ranked in the top 10 positions. Likewise, of the 160 cartridges of the five different brands correlated against the database, 21% ranked in the top 10 positions. Generally, the ranking position increased as the size of the RBID increased. We obtained similar results when we expanded the RBID to include firearms with the same class characteristics for breech face marks, firing pin impressions, and extractor marks. The results of our six queries against the RBID indicate that a reference ballistics image database of new guns is currently fraught with too many difficulties to be an effective and efficient law enforcement tool. 相似文献

Children's psychological adjustment following stressors, such as sexual abuse, is impacted by environmental variables. One such factor is parental support, which can be hampered when a caregiver suffers from psychopathology. The purpose of this study was to determine whether maternal depression would impact the children's adjustment to sexual abuse. It was hypothesized that depressed mothers would report more behavior difficulties for their sexually abused children than nondepressed mothers. Participants were 58 children (and their mothers) who were referred for trauma symptoms related to sexual abuse. Mothers completed the Beck Depression Inventory as a measure of their depression and rated their children's behaviors on the Revised Behavior Problem Checklist. The children completed the Children's Depression Inventory and the Revised Children's Manifest Anxiety Scale. Results revealed that depressed mothers reported more conduct problems, inattention/immaturity, and psychotic behavior than nondepressed mothers. Differences were not observed for mothers' report of depressive or anxious behaviors across groups. The children of depressed mothers reported increased levels of depression, but not anxiety, when compared to children of nondepressed mothers. Although both groups of mothers reported symptoms to be clinically significant, the children did not endorse their symptoms in clinically significant ranges. 相似文献

In the last decade, reforms in the public sector have been implemented at an ever‐increasing pace. Hereby, organizations are repetitively subject to mergers, splits, absorptions, or secessions of units; the adoption of new tasks; changes in legal status; and other structural reforms. Although evidence is largely missing in the literature, there is a growing belief that such intense reform sequences may be damaging to organizations. This article aims to fill this gap in the literature by empirically examining the existence of such repetitive change injury for public organizations. To do so, we employ organizational absenteeism rates as an indicator for repetitive change injury and link this to the reform sequences an organization experienced. Results indicate that intense reform sequences disproportionally increase organizational absenteeism rates, supporting the existence of repetitive change injury and suggesting that reforms remain rooted in organizational memories for a longer time than is often assumed. 相似文献

A frequent lament among researchers is that public policy makers should pay more attention to scientific and technical information (STI). If there is any single area where one might expect STI to be used in public policy making and agenda setting it is in science and technology policy. Many of the policy makers in science and technology policy are themselves scientists or researchers and presumably would prove especially receptive to STI. However, STI is only one of many types of information used in policy making and policy actors often differ in the extent to which they view STI as credible, particularly compared to other types of potentially policy‐relevant information. Research on credibility (the believability of information, information types, and media) has shown variance and policy makers’ “credibility maps.” Thus, some policy makers have preference for formal information generally and STI specifically, but others privilege raw data, personal experience, authority, history and anecdote, analogical reasoning, or conformance to ideology, to name just a few of the information choices. Here, we build on the current researchers’ previous bibliometrics‐based work and use data from 41 semi‐structured elite interviews with National Research Council (NRC) executives and staff and NRC committee members concerning the use of STI in reports issued by the NRC. Findings show that the use of STI in NRC reports varies according to the nature of the inquiry and the sponsor. Information used in the reports is based on not only the assessed credibility of information but also its perceived direct relevance and the availability of STI as compared to other types of information. In general, the amount of STI in the NRC reports tends to have modest effects on the likelihood that reports will be used in policy making or by the mass media. More important factors include the timing of the report with respect to political agendas, the party requesting the report, and the enacted roles of NRC staff members and committee chairs. 相似文献

A key feature of psychopathy, a self-centered orientation towards others and a failure to truly connect, is poorly understood. The attachment framework can be used to examine underlying interpersonal mechanisms. Because of the overall failure to connect, we anticipated, and found, in a large undergraduate sample (n?=?1074) that both affective-interpersonal traits and impulsive-irresponsible psychopathy facets were positively related to attachment avoidance. Different dynamics may underlie this distancing from others, as evidenced by the fact that callous-unemotionality was negatively related to attachment anxiety, whereas grandiose-manipulative and impulsive-irresponsible traits were positively related to attachment anxiety. Although effect sizes were small and are of correlational nature, our results are in line with a dual deficit model that differential developmental trajectories, largely heritable callousness vs. neglecting and abusive parenting, may lead to adult psychopathy. The differentiating role of fear of rejection and abandonment for the psychopathy construct is discussed. 相似文献
