Abstract: Tool mark identification relies on the premise that microscopic imperfections on a tool’s working surface are sufficiently unique and faithfully transferred to enable a one‐to‐one association between a tool and the tool marks it creates. This paper presents a study undertaken to assess the validity of this premise. As part of this study sets of striated tool marks were created under different conditions and on different media. The topography of these tool marks was acquired and the degree of similarity between them was quantified using well‐defined metrics. An analysis of the resulting matching and nonmatching similarity distributions shows nearly error‐free identification under most conditions. These results provide substantial support for the validity of the premise of tool mark identification. Because the approach taken in this study relies on a quantifiable similarity metric, the results have greater repeatability and objectivity than those obtained using less precise measures of similarity.  相似文献

Historically, fatal injury monitoring and surveillance have relied on mortality data derived from death certificates (DC). However, problems associated with utilizing DC have been well documented. Recently, access to and utilization of hospital discharge data (HDD) have offered a new and important secondary source of data regarding in-hospital deaths. However, studies have shown that discrepancies between the HDD and the corresponding DC often exist. This discrepancy was especially evident when comparing HDD to the vital statistics data (VSD) for deaths by falls among those aged 65 and over in 19 states.This was a retrospective forensic review of elderly (age 65 and over) fall-associated fatalities (E880-E888) identified from HDD and VSD in Allegheny County, Pennsylvania, between 1997 and 1998. Seventy-seven cases were identified, with the original manner of death listed as natural (34), suicide (1), and accidental (42) on the DC. Following a forensic review of the cases, the manner of the death on the DC should have been changed from natural to accidental in 28% (n = 12) of the cases, representing an undercount in the VSD. Undercounts were due to a failure of clinicians to account for the significance of a fall event that contributed to subsequent pathology and death. In addition, in that 22% (n = 17) of the HDD fall-associated deaths, the fall did not contribute directly or sequentially to the underlying cause of death, thereby representing an overcount in the HDD.Based on these findings we recommend (1) elderly fall surveillance systems should only count HDD E-coded falls that demonstrate a serious traumatic injury which directly or subsequently results in death, (2) all in-hospital fall-associated deaths should be reported to and reviewed by coroner/Medical Examiner offices for determination of the cause and manner of death, and (3) physicians should be better educated in properly completing death certificates.  相似文献

Estimates indicate hate crimes are a growing concern in the United States. This paper addresses how criminal justice students perceive victims of hate crimes. Survey findings show subjects are less likely to define certain groups of people as victims of hate crimes. Suggestions are made as to how criminal justice departments can heighten awareness of hate crime victims, multiculturalism, and gender diversity among criminal justice students.  相似文献

Purpose

To assess differences in victimization risk between African American and white, non-Latino inmates, and to estimate race group differences in the correlates of victimization.

Methods

Random samples totaling 2,403 African Americans and 3,150 whites were drawn from all state prisons in Ohio and Kentucky and all private prisons in Ohio (n = 46). Race-specific bi-level models of physical assaults and property thefts were estimated. Differences between race-specific models in the magnitude of regression coefficients for the same predictors and outcomes were compared.

Results

The odds of victimization by physical assault and by theft were significantly higher among whites compared to African Americans. Race group differences in the magnitude of several inmate level effects (e.g., age, sex, education, family status, officer “legitimacy”, custody score, visitation) were also significant, yet facility effects were similar for both groups.

Conclusions

Assessing differences in the victimization experiences of African American and white inmates is important for developing effective crime prevention strategies in prison. We examined the most comprehensive models of inmate victimization (including inmate socio-demographics, activities during confinement, perceptions of officers, facility characteristics, and officer perceptions of rule enforcement) for one of the largest samples of prisons to date.  相似文献
