A Large‐Sample Test of a Semi‐Automated Clavicle Search Engine to Assist Skeletal Identification by Radiograph Comparison 下载免费PDF全文
Susan S. D'Alonzo M.A. Pierre Guyomarc'h Ph.D. John E. Byrd Ph.D. Carl N. Stephan Ph.D. 《Journal of forensic sciences》2017,62(1):181-186
In 2014, a morphometric capability to search chest radiograph databases by quantified clavicle shape was published to assist skeletal identification. Here, we extend the validation tests conducted by increasing the search universe 18‐fold, from 409 to 7361 individuals to determine whether there is any associated decrease in performance under these more challenging circumstances. The number of trials and analysts were also increased, respectively, from 17 to 30 skeletons, and two to four examiners. Elliptical Fourier analysis was conducted on clavicles from each skeleton by each analyst (shadowgrams trimmed from scratch in every instance) and compared to the search universe. Correctly matching individuals were found in shortlists of 10% of the sample 70% of the time. This rate is similar to, although slightly lower than, rates previously found for much smaller samples (80%). Accuracy and reliability are thereby maintained, even when the comparison system is challenged by much larger search universes. 相似文献

Revolving Roles in Drug-Related Crime: The Cost of Chronic Drug Users as Victims and Perpetrators 总被引:1,自引:0,他引:1
Michael T. French Kathryn E. McCollister Pierre Kébreau Alexandre Dale D. Chitwood Clyde B. McCoy 《Journal of Quantitative Criminology》2004,20(3):217-241
Numerous studies have established a strong connection between the use of illicit drugs and the commission of other illegal activities, including both predatory and property crimes. No study, however, has examined the cost of crimes associated with drug users both as victims and as perpetrators. In the present study, recent data were analyzed from a targeted sample of chronic drug users (CDUs) and a matched sample of non-drug users (NDUs) in Miami-Dade County, Florida, to estimate the incremental cost of crime associated with CDU. Two separate models were employed to estimate (1) the probability of being a victim or a perpetrator of crime and (2) the cost of crime for both situations. The cost measures were transformed to reduce the influence of extreme outliers, and a smearing technique was used to compare the cost of crime for CDUs relative to NDUs. The findings illustrate that criminal activity among CDUs is circular, extensive, and costly. Implications for law enforcement, criminal justice policy, and substance abuse treatment are discussed. 相似文献
