Stature estimation using foot dimensions via 3D scanning in Taiwanese male adults

In forensic identification, the use of foot dimensions to predict stature is a requisite. For Taiwanese male stature prediction, available information about stature estimation using foot dimensions is still lacking. Therefore, the primary purpose of this study was to establish Taiwanese adult male stature prediction models for various foot dimensions. A total of 2,072 male 3D foot models were collected and the subjects' ages ranged from 18 to 59 years old. Thirteen foot dimensions for each foot were utilized in this study. Bilateral differences were tested using paired t-tests. Stature predictions based on different foot dimensions were conducted using simple linear and stepwise regression methods. The results showed significant bilateral differences in the majority of the selected foot dimensions (p < 0.001). Foot length had the highest positive correlation with stature in the right and left foot. Using length-related dimensions generated better prediction accuracy (0.356 < R² < 0.533, 4.193 < SEE < 4.928), whereas the worst accuracy was observed with angle-related dimensions (0.001 < R² < 0.023; 6.072 < SEE < 6.137) when employing a single foot dimension to estimate Taiwanese male stature. Stepwise regression analysis results indicated that the coefficient of determination was improved to 0.590 and 0.593 by applying five and six foot parameters to predict stature, respectively. The findings of the present study suggest that these stature estimation equations can be applied to predict Taiwanese male stature in the forensic science field.     

大数据时代下的主动型侦查模式研究

侦查模式是侦查的最一般路由,侦查人员借助其对案件侦查形成基本的工作思路.当前犯罪出现了动态化、智能化、组织化的异化现象,处于基础性地位的反应型侦查模式在应对犯罪异化时遇到了困难.本文研究反应型侦查向主动型侦查转型的相关问题,借助了大数据对于行为、事件的预测功能扩展了原有的主动型侦查模式适用的外延范围并厘清了其在适用时所要解决的与反应型侦查所不同的法律问题.     

对信息化时代女性话语仍被“消音“的再思考

网络的出现为两性的平等提供了潜力,但在父权制的社会里,这一新事物仍使女性处于“话语权”被消音的状况中。尽管现状并不很乐观,但还是存在着改变的潜力和希望的。     

大鼠皮肤挫伤修复过程中NF_κB P65表达的研究

目的探讨皮肤挫伤修复过程中,核转录因子(NFkB)P65在挫伤区不同时间表达的变化规律。方法 应用免疫组化技术对挫伤后0h、3h、6h、9h、12h、1d、3d、5d、7d、10d的大鼠皮肤挫伤组织中NFkB P65的表达进行研究。结果伤后3h,挫伤区内浸润的少量多核粒细胞的胞质中NFkB P65呈弱阳性表达,阳性率为(3.20％±0.15％);伤后6h,阳性表达增强,阳性率为(11.33％±0.88％);伤后12h,表达继续增强,阳性率(75.67％±0.82％);伤后1d,在浸润的几乎所有单核细胞和多核粒细胞的胞质和胞核中均可见NFkB P65呈强阳性表达,阳性率为(97.33％±0.88％),表达达高峰,以后逐渐下降。结论 大鼠皮肤挫伤修复过程中,NFkB P65在挫伤后的炎症反应中发挥重要作用;同时,NFkB P65在挫伤区内多核粒细胞,单核细胞及成纤维细胞中的表达呈规律性变化,可对挫伤时间的推断提供参考。     

创缘周围血管生成在皮肤损伤时间推断中的应用

皮肤损伤时间推断一直以来都是法医病理学者所需解决的重要问题,免疫组织化学技术具有方便、敏感的特性,它的应用大大提高了皮肤损伤时间推断研究的发展。然而,有效指标的缺乏却限制了免疫组织化学技术的应用。血管生成在皮肤损伤愈合过程中发挥着非常重要的作用,因此,血管生成相关因子可能在皮肤损伤时间推断方面具有重要价值。

刑事责任年龄认定存在的问题及对策研究

由于立法上缺乏刑事责任年龄认定标准;司法实践中户籍资料、被告人供述和辩解、证人陈述和骨龄鉴定认定依据均存在问题;刑事证据采纳标准和司法成本影响刑事责任年龄的认定,从而导致犯罪嫌疑人尤其是未成年人刑事责任年龄的认定处于不确定状态。对此,立法上应明确规定认定刑事责任年龄的法律依据;司法实践中,严格户籍管理,适当运用骨龄鉴定,严格遵守证据的采信规则,合理规划司法成本。

Cross-national comparison of homicide: Age/sex-adjusted rates using the 1980 U.S. homicide experience as a standard

Cross-sectional studies of crime have typically relied on crude crime rates when making comparisons between countries. Crude rates control for population size but implicitly assume that all members of the population are equally at risk. Empirical studies have shown that, cross-nationally, risk varies by age and sex. Standardization of crime rates removes the confounding effects of variable age and sex population distributions. Since age/sex-specific crime rates are generally unavailable for many countries, the method of indirect standardization is the most desirable technique. Age/sex-adjusted homicide rates for 76 countries are presented, and two comparative measures are suggested. It is shown that while the United States has a higher homicide rate than all but 15 countries; in most cases, the magnitude of the difference, not controlling for age/sex differences, is overestimated. Crude rates underestimate differences between the United States and countries with higher rates of homicide.
