Sexual dimorphism in the humerus: a comparative analysis of Chinese, Japanese and Thais

Determination of sex from the skeleton is vital to medicolegal investigations. There is no longer any question that populations differ in size and proportions and these differences affect the metric assessment of sex. The extent of variation in sexual dimorphism among Asian Mongoloids within and between regions has not been quantified by discriminant function analysis, nor have standards for most groups been introduced for the humerus. Therefore, the purpose of this research is to establish metric standards for sex determination from the humerus of Chinese, Japanese and Thais, as well as to compare size and sexual dimorphism in these Asian Mongoloid populations. The database for this study consisted of documented skeletal samples from China (N = 87), Japan (N = 90), and Thailand (N = 104). Six standard dimensions, including maximum length, vertical head diameter, minimum midshaft diameter, maximum midshaft diameter, midshaft circumference, and epicondylar breadth were taken and subjected to stepwise and direct discriminant function analysis. Of dimensions selected by the stepwise function, vertical head diameter and epicondylar breadth were the only elements common to all three groups. Overall, mean accuracies were highest using formulae produced by the stepwise procedure and ranged from 86.8% in the Chinese to 92.4% in the Japanese to 97.1% in the Thais. Group comparisons also revealed that while the Chinese had the largest measurements, they were the least dimorphic. The reverse was true for the Thais and the Japanese were intermediate on both counts. In cross validation tests, classification accuracy decreased in all cases where a formula from one group was applied to another. It was therefore concluded even though all individuals were Asian Mongoloids, these regionally diverse populations exhibited significant metric differences that affect sex determination from the skeleton. These findings confirm those of previous studies that there is a need for group specific metric standards of assessment.     

解困行政审批改革的新路径

新一轮如火如荼开展的行政审批改革,并没有呈现出摆脱运动化、形式化痼疾的明显迹象,行政审批边减边增、明减暗增问题依然严重。行政许可法集中收拢设定权、加强公众参与、提供自由主义标准以及明确事后跟踪评价等规制方案,无力使行政审批改革脱困于结构性制约。克服困境的思路之一,是关注行政体系和过程内部的结构设计,以及这种内部结构嵌入外部结构的整个系统,通过专门的行政改革委员会、开放的研究计划和议程设置、公众和专家充分参与的民主商议、年度和专题的行政改革研究报告以及试验改革的授权制度等机制,使行政审批改革常态化、持续化、规范化。
