This paper presents a coherent probabilistic framework for taking account of allelic dropout, stutter bands and silent alleles when interpreting STR DNA profiles from a mixture sample using peak size information arising from a PCR analysis. This information can be exploited for evaluating the evidential strength for a hypothesis that DNA from a particular person is present in the mixture. It extends an earlier Bayesian network approach that ignored such artifacts. We illustrate the use of the extended network on a published casework example. 相似文献

农村基层组织职务犯罪的上升趋势,反映出农村基层社会管理出现了一些问题。基层干部人员素质较低,监管力度不够,财务管理混乱等主客观因素是犯罪率上升的直接原因。因此。必须加大社会管理创新力度,认真贯彻落实修订后的《中华人民共和国村民委员会组织法》和中共中央办公厅、国务院办公厅《关于在农村普遍实行村务公开和民主管理制度的通知》,形成全方位预防“村官”职务犯罪的监督体系。 相似文献

在女性群体中有一个特殊的人群--农村水库移民女性.从对移民家庭发展历程中经历的搬迁、建房和土地利用这三个生活场景变迁的描述中可以看出,作为妻子和母亲双重角色的移民女性群体的社会适应过程,及其对抗危机策略中所表现的灵活实用和开放发展的特质. 相似文献

我国农村环境污染日趋严重,对农民的生命健康权和财产权造成了较严重损害,但农民对环境污染的救济却存在多重困难,应从价值层面强化维护农民生存权的法治理念,并从制度层面强化政府的环保职责和提高农民的救济能力。 相似文献

Estimation of age in individuals has received considerable attention in forensic science, in which it is a widely used method for individual identification, together with paleo-demographic analyses to establish mortality patterns in past populations. The present investigation, which is a continuation of a previously published pilot study, was conducted to examine the possible application of the pulp/tooth area ratio by peri-apical images as an indicator of age at death. A total of 200 peri-apical X-rays of upper and lower canines were assembled from 57 male and 43 female skeletons of Caucasian origin, aged between 20 and 79 years. They belong to the Frassetto osteological collection of Sassari (Sardinia) and are housed in the Museum of Anthropology, Department of Experimental and Evolutionistic Biology, University of Bologna. For each skeleton, dental maturity was evaluated by measuring the pulp/tooth area ratio on upper (x(1)) and lower (x(2)) canines. Very good agreement was found between intraobserver measurements. Statistical analysis was performed in order to obtain multiple regression formulae for dental age calculation, with chronological age as dependent variable, and gender, and upper and lower canines as independent variables. Stepwise regression analysis showed that gender did not contribute significantly to the fit (p=0.881) whereas variables x(1) and x(2) and the first-order interaction between them did. These two variables explained 92.5% of variations in estimated chronological age and the residual standard error was 4.06 years. Lastly, two simple linear regression equations were obtained for age estimation using canines from the maxilla and mandible separately. Both models explained 86% of variations in estimated chronological age and allowed an age-at-death estimate with a residual standard error of about 5.4 years. 相似文献

Changes in the size of the pulp canal, caused by apposition of secondary dentine, are the best morphometric parameters for estimating age by X-rays. The apposition of secondary dentine is the most frequently used method for age estimation in adult subjects. In two previous papers, we studied the application of the pulp/tooth area ratio by peri-apical X-rays as an indicator of age at death. The aim of the present study was to test the accuracy of age evaluation by combined analysis of labio-lingual and mesial peri-apical X-rays of lower and upper canines. A total of 200 such X-rays were assembled from 57 male and 43 female skeletons of Caucasian origin, aged between 20 and 79 years. For each skeleton, dental maturity was evaluated by measuring the pulp/tooth area ratio according to labio-lingual and mesial X-rays on upper (x(1), x(2)) and lower (x(3), x(4)) canines. Very good agreement was found between intra-observer measurements. Statistical analysis showed that all variables x(1), x(2), x(3), and x(4) and the first-order interaction between x(1) and x(3) contributed significantly to the fit, so that they were included in the regression model, yielding the following regression formula: Age = 120.737 - 337.112x(1) - 79.709x(2) - 364.534x(3) - 65.655x(4) + 1531.918x(1)x(3) . The residual standard error of estimated ages was 3.62 years, with 94 degrees of freedom, and the median of the residuals was -0.155 years, with an interquartile range of 4.96 years. The accuracy of the method was ME = 2.8 years, where ME is the mean prediction error. The model also explained 94% of total variance (R(2) = 0.94). 相似文献

As the policy discussions of historic preservation have become complicated in recent years, the advocacy for the use of heritage is now even more important, and the number of coalitions for promoting the economic value of heritage has been on the rise. This research provides a historical view of the development of advocacy coalition networks that actively pursue the benefits of heritage resources. Through this context, the article then examines a case study of the Wheeling National Heritage Area. The case exemplifies the framework of how coalition networks can provide the structure necessary to push preservation policy in government. 相似文献
