根据中国汉族女性甲状软骨推算年龄的研究

目的 根据中国汉族女性甲状软骨推算年龄。方法 对69例已知年龄的中国汉族女性甲状软骨进行软X线摄片和(或)普通X线摄片,从甲状软骨的摄片上选择5个与年龄变化关系较为密切的观察部位,每个部位又划分成3至6个等级,然后采用多元线性回归分析法,建立其推算年龄的数学模型。结果运用该方法推算女性甲状软骨年龄,其标准差为1.969,复相关系数为0.984。结论 本方法适用于中国汉族女性甲状软骨年龄推算,其有效年龄范围为18～60岁。

Locking up my generation: Cohort differences in prison spells over the life course

Crime rates have dropped substantially in the United States, but incarceration rates have remained high. The standard explanation for the lasting trend in incarceration is that the policy choices from the 1980s and 1990s were part of a secular increase in punitiveness that has kept rates of incarceration high. Our study highlights a heretofore overlooked perspective: that the crime–punishment wave in the 1980s and 1990s created cohort differences in incarceration over the life course that changed the level of incarceration even decades after the wave. With individual-level longitudinal sentencing data from 1972 to 2016 in North Carolina, we show that cohort effects—the lingering impacts of having reached young adulthood at particular times in the history of crime and punishment—are at least as large (and likely much larger) than annual variation in incarceration rates attributable to period-specific events and proclivities. The birth cohorts that reach prime age of crime during the 1980s and 1990s crime–punishment wave have elevated rates of incarceration throughout their observed life course. The key mechanism for their elevated incarceration rates decades after the crime–punishment wave is the accumulation of extended criminal history under a sentencing structure that systematically escalates punishment for those with priors.     

Urea,Uric Acid,and Creatinine in Postmortem Blood,Vitreous Humor,and Synovial Fluid: A Comparative and Correlation Study,

Urea, uric acid, and creatinine have been demonstrated to be relatively stable in postmortem blood (BL), thus being useful for diagnostic purposes. However, no studies have explored their levels in BL, vitreous humor (VH), and synovial fluid (SF) concurrently. Therefore, we measured and compared their levels in these fluids. We also determined the effects of various factors on their levels. The results indicated that BL urea, uric acid, and creatinine levels were significantly higher than VH and SF levels. VH and SF urea levels and SF creatinine levels had a strong correlation with BL urea and creatinine levels, respectively. BL creatinine levels were higher in men than in women. BL and SF creatinine levels were negatively correlated with age. SF uric acid and BL, VH, and SF creatinine levels exhibited a positive correlation with weight. Only VH creatinine levels were positively correlated with body mass index. None of urea, uric acid, and creatinine levels were correlated with postmortem interval.     

Rib Variation at Multiple Locations and Implications for Histological Age Estimation*

Existing histological age estimation methods using the rib were developed mainly from the midshaft; however, in forensic practice, uncertainty of sampling location often arises due to fragmented or previously sampled ribs. The potential for error increases when sampling location is uncertain and utilizing a section beyond the midshaft (either anterior or posterior) may result in erroneous age estimates. Additionally, there is debate within the field regarding the minimum number of sections needed for accurate age estimation. The aim of this research is to determine the importance of the midshaft distinction for age-at-death assessment and the necessity of analyzing serial sections by evaluating histological variables at sampling locations along the length of the rib. Three seriated histological sections at three sampling locations (anterior, midshaft, and posterior) were obtained from sixth ribs of ten postmortem human subjects. Cortical area (Ct.Ar) and osteon population density (OPD) were collected from each section (n = 90). Significant differences were determined in Ct.Ar between sampling locations, demonstrating the variation present along the length of the rib. A comparison of OPD at sampling locations revealed significant differences, suggesting that sampling site is critical to accurate age estimates. When sampling location is uncertain, a more anterior section should be taken. Analysis of serial sections within locations revealed no significant differences in OPD or Ct.Ar, supporting the practice of collecting data from one section for age estimation. While an age estimate can be achieved through the analysis of one section, best practice suggests reading two sections to capture intraindividual variation.     

关于提高女性劳动者退休年龄的探讨

关于提高中国退休年龄问题,近来引发了社会各界的广泛关注。文章深入分析了广泛关注的几个因素:平均余命变化,世界的退休年龄变化趋势以及对于劳动力市场的影响,并进一步分析了当前制度规定下女性退休年龄偏低产生的低收益及退而不休现象及其影响。在此基础上,文章建议:中国应当提高女性退休年龄;结合劳动力人口变化趋势,采用小步渐进的方式进行调整。好处在于:在一定程度上解决女性退休后低收益问题,因而可以缓解退而不休现象;在一定程度上优化劳动力市场供给。     

Caveat: addressing public justification as an empirical phenomenon

ABSTRACT

Instead of a conclusion, this special issue ends with a discussion between Liah Greenfeld, on the one hand, and Uriel Abulof and Markus Kornprobst, on the other hand, about the merits of studying public justification and how best to do so. Greenfeld suggests that public justification is predicated on the autonomy of the political sphere, the importance ascribed to public views, and to the prevalence of justification. Seeing public justification as ultimately a cultural phenomenon, this caveat urges scholars to study it in only specific historical contexts, which are, for now, limited to predominantly ‘Western liberal democracies’.
