There is currently no published empirical evidence‐base demonstrating 3D printing to be an accurate and reliable tool in forensic anthropology, despite 3D printed replicas being exhibited as demonstrative evidence in court. In this study, human bones (n = 3) scanned using computed tomography were reconstructed as virtual 3D models (n = 6), and 3D printed using six commercially available printers, with osteometric data recorded at each stage. Virtual models and 3D prints were on average accurate to the source bones, with mean differences from ?0.4 to 1.2 mm (?0.4% to 12.0%). Interobserver differences ranged from ?5.1 to 0.7 mm (?5.3% to 0.7%). Reconstruction and modeling parameters influenced accuracy, and prints produced using selective laser sintering (SLS) were most consistently accurate. This preliminary investigation into virtual modeling and 3D printer capability provides a novel insight into the accuracy of 3D printing osteological samples and begins to establish an evidence‐base for validating 3D printed bones as demonstrative evidence.  相似文献

A 19-year-old G1P0 Caucasian woman died 8 days postpartum because of the subinvolution of the uteroplacental arteries. Microscopic examination of the placental implantation site revealed large, dilated spiral arteries containing partially occluding thrombi in the superficial myometrium. The presence of cytotrophoblasts within and surrounding the spiral arteries was confirmed by low molecular weight cytokeratin immunohistochemistry. Infection of the Cesarean section incision site was demonstrated by the growth of Staphylococcus aureus and Streptococcus agalactiae Group B in the wound as well as the intrauterine blood clot. Although subinvolution of the placental site may be a cause of delayed postpartum hemorrhage and significant morbidity, the underlying pathophysiologic mechanism is unknown.  相似文献

Suicide by asphyxiation using helium is the most widely-promoted method of "self-deliverance" by right-to-die advocates. However, little is known about persons committing such suicides or the circumstances and manner in which they are completed. Prior reports of suicides by asphyxiation involving helium were reviewed and deaths determined by the North Carolina Office of the Chief Medical Examiner to be helium-associated asphyxial suicides occurring between January 1, 2000 and December 31, 2008 were included in a new case series examined in this article. The 10 asphyxial suicides involving helium identified in North Carolina tended to occur almost exclusively in non-Hispanic, white men who were relatively young (M age = 41.1 T 11.6). In 6 of 10 cases, decedents suffered from significant psychiatric dysfunction; in 3 of these 6 cases, psychiatric disorders were present comorbidly with substance abuse. In none of these cases were decedents suffering from terminal illness. Most persons committing suicide with helium were free of terminal illness but suffered from psychiatric and/or substance use disorders.  相似文献

Actuarial risk assessment instruments for sexual offenders are often used in high-stakes decision making and therefore should be subject to stringent reliability and validity testing. Furthermore, those involved in the risk assessment of sexual offenders should be aware of the factors that may affect the reliability of these instruments. The present study examined the interrater reliability of the Risk Matrix 2000/s between one field rater and one independent rater with a sample of more than 100 sexual offenders. The results indicated good interrater reliability of the tool, although reliability varies from item to item. A number of factors were identified that seem to reduce the reliability of scoring. The present findings are strengthened by examining interrater reliability of the tool in the usual practitioner context and by calculating a range of reliability statistics. Strategies are suggested to increase reliability in the use of actuarial tools in routine practice.  相似文献

A recent case from the English Court of Appeal (R (on the application of Condliff) v North Staffordshire Primary Care Trust [2011] EWCA Civ 910, concerning denial by a regional health care rationing committee of laparoscopic gastric bypass surgery for morbid obesity) demonstrates the problems of attempting to rely post hoc on human rights protections to ameliorate inequities in health care reforms that emphasise institutional budgets rather than universal access. This column analyses the complexities of such an approach in relation to recent policy debates and legislative reform of the health systems in the United Kingdom and Australia. Enforceable human rights, such as those available in the United Kingdom to the patient Tom Condliff, appear insufficient to adequately redress issues of inequity promoted by such "reforms". Equity may fare even worse under Australian cost-containment health care reforms, given the absence of relevant enforceable human rights in that jurisdiction.  相似文献

Reparations for victims of gross human rights violations arebecoming an increasingly acknowledged feature in post-authoritarianand post-conflict societies coping with the legacy of a violentpast. Despite some recent progress much more work needs to bedone for massive reparations programs to respond better to theneeds of women. This article, resting as it does on a comprehensiveconception of reparations, outlines both the procedural andsubstantive components of reparations programs necessary forthe programs to fulfill the goal of providing (partial) justiceto women.  相似文献
