Investigations of perinatal deaths often result in discrepancies between autopsy findings and witness accounts. The mechanism by which the umbilical cord is severed after delivery is a common quandary. Confirming or refuting the mother's stated method frequently has significant investigative importance; however, a surprising paucity of data currently exists to allow an objective opinion about the likely mechanism. Ninety-nine placentas with umbilical cords were examined. By random selection, each cord was severed by one of the following tools or mechanisms: knives, scissors, traction, or crush. Each break was examined and photographed, and a tissue section from the broken end examined microscopically. Differentiation of mechanism was best done grossly based on specific pattern recognition. Umbilical cords severed by blunt force have distinctly different morphology from those severed by sharp force. Even similar-appearing sharp force transections frequently have mechanism-specific distinctive patterns of injury. 相似文献

Recent British Election Studies have asked respondents to nominate ‘the most important issue’. Responses to this question have been used to explain individual vote decisions and characterise the issue-component of those elections. This paper, however, finds limited evidence that individuals place more weight on those issues that they report as ‘most important’ when they vote. It also finds that aggregate responses to the MII question broadly match the estimated ‘average’ impact of those issues on voters. This suggests that even if voters have a limited understanding of what issues matter to themselves they have some understanding of what makes their fellow voters tick. 相似文献

Auricular Surface Aging: Comparing Two Methods that Assess Morphological Change in the Ilium with Bayesian Analyses 下载免费PDF全文
Modern standards in forensic anthropology require rigorous testing and evaluation of methods used for aging skeletal remains. Age estimation has been criticized for bias, inaccuracy, and population specificity; issues which are minimized by the application of Bayesian methodology. Using Bayesian statistics, we compare the Lovejoy et al. (Am J Phys Anthropol, 68, 1985, 15) (original) and Buckberry and Chamberlain (Am J Phys Anthropol, 119, 2002, 231) (revised) auricular surface aging methods. Transition analysis parameters derived from American males (n = 372), in combination with a Thai male (N = 37) informative prior, statistically model age in Portuguese males (n = 221). Cumulative binomial tests assess the accuracy of the generated age ranges. Overall, the application of transition analysis and Bayesian statistics significantly improved age estimation with both methods (also outperforming Suchey‐Brooks pubic symphysis aging). Moreover, the accuracy of the original method was low without statistical modeling, whereas the revised method can be applied accurately without further statistical analysis. Additionally, reference tables for aging Portuguese males are provided. 相似文献

Abstract This research investigates the where and when of sexual assaults to determine what types of sexual crimes are committed at different time and place classifications. Exhaustive CHAID (chi-squared automatic interaction detection) analyses are conducted, examining factors associated with crimes that were committed indoors or outdoors, in private or public places, during the day or at night, and during the week or on the weekend. These methods are applied to a sample of 361 sexual crime events committed by 72 serial sex offenders. The results are strikingly different dependent on which spatial or temporal aspect of the crime is examined, which implies the complexity of sexual crime events and their situational components. This research brings to light possible policy implications with respect to situational crime prevention. 相似文献

Evidence suggests sanitation development is more effective when women are involved. The purpose of this study was to provide women with an opportunity to share their perspectives and solutions to sanitation in informal settlements. Data were collected through 55 in-depth interviews with women in Mathare Valley informal settlement in Nairobi, Kenya. The most common solution was to build more toilets, but women had a variety of suggestions – including gender-specific solutions. Findings from this study suggest that it is imperative to start addressing women-specific burdens associated with sanitation in informal settlements. 相似文献
