The traditional histology method typically employed by forensic anthropologists involves plastic embedding of undecalcified bone. The embedded sample is then cut by a diamond blade saw and ground to the required thickness of ~50–100 microns using a grinder. There are several limitations to this method: Cement lines may be blurred; depth‐of‐field artifacts may result from viewing thick sections; and medicolegal offices with limited budgets may not be able to invest in additional equipment or training for this method. A silver nitrate stain modification of the standard histology preparation technique of decalcified bone is presented. The benefits of this technique are that: Cement lines are viewed clearly; no depth‐of‐field artifacts are present; and because this is a modification of the standard technique used by histology laboratories typically employed by medicolegal offices, no additional equipment or training is required. 相似文献

Presence of diatoms in tissues has been considered as a significant sign of drowning. However, there are limitations in the present extraction methods. We developed a new digestion method using the Lefort aqua regia solution (3:1 nitric acid to hydrochloric acid) for diatom extraction and evaluated the digestive capability, diatom destruction, and diatoms' recovery of this new method. The kidney tissues from rabbit mixed with water rich in diatoms were treated by the Lefort aqua regia digestion method (n = 10) and the conventional acid digestion method (n = 10). The results showed that the digestive capability of Lefort aqua regia digestion method was superior to conventional acid digestion method (p < 0.01); the structure of diatom remained almost intact; and the recovery of diatom was comparable to the conventional acid digestion method (p > 0.05). The Lefort aqua regia reagent is an improvement over the conventional acid digestion for recovery of diatoms from tissue samples. 相似文献

This article investigates marital patterns in the urban town of Vila do Conde, northwest Portugal, during the 19th century. The analysis, which is based on the application of the family reconstitution method, reveals differences in marital patterns between rural and urban settlements. It was observed that Vila do Conde displayed different patterns of marriage than those that have often been described for the northwestern region of Portugal, with an emphasis on lower levels of celibacy, as well as lower fertility rates. It was discovered that migration played a very important role in these dynamics. It is a fact that the increasing outflow of male emigrants had a distortion effect on the marriage market. Nevertheless, the influx of in-migrants to the town contributed to alleviate the adult male shortage and resulting gender imbalance, generating lower proportions of celibacy and higher levels of total fertility. Although several important publications have already identified demographic trends in many parishes of the region in focus, few have been concerned with urban parishes. This research aims to contribute to a better understanding of the population dynamics of urban centres in northwest Portugal when set within the context of a number of the structural changes specific to that region and Portugal as a whole in the 19th century. 相似文献

Anyone who attempts to understand and reverse the major defeat suffered by Labour in the December 2019 general election needs first to appreciate why comparisons with the defeats of the 1980s are so unhelpful. In 1983 Labour was all but wiped out across southern England, but held on comfortably across the ‘red wall’. By contrast, in 2019 Labour did well in cities and university towns across the south, and appears to have solved its historic problem with the southern, educated middle class. However, this has been at the expense of alienating working class voters across the country, not just in its former industrial heartlands. But this is not inevitable. A reanalysis of testimony from hundreds of interviews with working people across England from the 1940s onwards allows insights into attitudes and values that are often obscured by survey techniques. Crucially, it points to a broad-based vernacular liberalism at odds with the culture wars model of a terminal crisis for social democracy. 相似文献

随着当前对天然药物开发研究的不断深入,天然药物化学课程的重要性也越来越受到重视。而传统的天然药物化学教学方式多为教师讲授,学生被动地听、甚至靠死记硬背,学生的学习兴趣没有得到激发,效率不高,普遍反映枯燥难学。因而全面提高天然药物化学的学习水平和教学质量具有重要意义。为此,作者结合自己的教学经验谈一些感受。 相似文献

纯理性的、纯思辨的分析在法学研究中的局限性越来越明显,司法实践越来越需要实证分析的方法.实证分析的方法,就是如何获得知识的知识,怎样获得一个研究成果的过程和方法.实证分析强调三个意识:样本意识、量化意识、半知意识,还必需具备三个条件:理论资源、案例资源、量化分析手段. 相似文献

就业协议是我国高等院校要求应届毕业生与用人单位签订的有关毕业生工作的协议,可以作为统计就业率,确定毕业生就业单位的依据.但实践中对就业协议的性质不清、内容存在问题,导致就业协议存在虚假签约、毁约现象比较严重,有必要对就业协议进行改革,用法律手段调整毕业生与用人单位的关系. 相似文献

人们对刑法的解释不应当仅仅关注刑法解释的结论,而应当更多地关注刑法解释过程中的指导思想和原则。学界对刑法解释的规则多有分歧。这些分歧体现了学者们在刑法解释的哲理层面的对立与分歧。它们中的每一种观点的哲理基础都有一定的合理性,然而又都并非无懈可击。刑法解释的规则应当是一种多层次的顺次检讨规则。 相似文献
