A mixed DNA profile controversy revisited

Semaan et al. (J Forensic Res, 2020, 11, 453) discuss a mock case “where eight different individuals [P₁ through P₈] could not be excluded in a mixed DNA analysis. Even though … expert DNA mixture analysis software was used.” Two of these are the true donors. The LRs reported are incorrect due to the incorrect entry of propositions into LRmix Studio. This forced the software to account for most of the alleles as drop-in, resulting in LRs 60–70 orders of magnitude larger than expected. P₁, P₂, P₄, P₅, and P₈ can be manually excluded using peak heights. This has relevance when using LRmix which does not use peak heights. We extend the work using the same two reference genotypes who were the true contributors as Semaan et al. (J Forensic Res, 2020, 11, 453). We simulate three two-donor mixtures with peak heights using these two genotypes and analyze using STRmix?. For the simulated 1:1 mixture, one of the non-donors’ LRs supported him being a contributor when no conditioning was used. When considered in combination with any other potential donors (i.e., with conditioning), this non-donor was correctly eliminated. For the 3:1 mixture, all results correctly supported that the non-donors were not contributors. The low-template 4:1 mixture LRs with no conditioning showed support for all eight profiles as donors. However, the results from pair-wise conditioning showed that only the two ground truth donors had LRs supporting that they were contributors to the mixture. We recommend the use of peak heights and conditioning profiles, as this allows better sensitivity and specificity even when the persons share many alleles.     

加入WTO与中国内外资企业法律制度分析

审视我国现行的内外资企业法律制度,其与市场经济法治要求有一定的距离,并且存在着诸多与 WTO 规则相背离的地方。我们应本着经济立法是对客观经济规律地正确反映的指导思想,制定反映我国社会主义市场经济要求的内外资企业法律制度。     

单一大关节判定男性青少年骨龄可靠性的比较研究

通过男性青少年单一关节X线片判定年龄是快速、简便的一种方法,但这些方法哪一种更准确尚无系统研究。本文研究了100例正常男性青少年X线片(13~18岁)对单一大关节判断年龄的结果进行了初步比较,结果发现在不同年龄段每种方法的准确性是不同的。在15~16岁之前,百分位数法、CHN法、肩关节法、肘关节法和腕关节法准确性更高些。在15~16岁之后,六大关节法、膝关节法、踝关节法和髋关节法的准确性更好。

贵州资源环境与人口的协调发展

贵州的自然环境及丰富的地产资源是发展经济的优势。但是人口的增长及封闭传统文化限制了经济的发展,经济的落后又导致了人口的增长。因此,加快经济建设的步伐,首先必须加强人口的控制。有效地利用和保护资源环境使其得以合理的综合利用,是贵州民族经济可持续发展的重要课题。     

Influence of electricity on post-mortal body temperature

In a case of suicidal application of electricity differences between the rectal temperature of the body and the suspected time of death were observed.In order to answer the question whether an electric current from hand to hand over >30 min led to a rise in body temperature FEM-based computer simulations and animal experiments were carried out. Both resulted in a warming of the soft parts in the arm without warming the body core. Thus a temperature-based estimation of the time since death can also be used in cases with electricity as the cause of death. Besides, in the animal experiment we found a spontaneous rise in the body core temperature even without application of electricity which may be a reason for the typical temperature plateau after death.

撒哈拉以南非洲的人口问题与可持续发展

在非洲人口与经济发展关系的研究中,世界最不发达的撒哈拉以南非洲具有其典型性,深入研究其人口增长与经济发展的严重失衡、人口的科学文化素质低下特别是高文盲率和人口健康素质低劣特别是因艾兹病泛滥而导致的人口高死亡率及其它一系列问题,可以明显地看到这些问题对经济发展产生的诸多不利影响,以及它们对该地区的可持续发展带来的严峻挑战。
