STR analysis of artificially degraded DNA-results of a collaborative European exercise

Degradation of human DNA extracted from forensic stains is, in most cases, the result of a natural process due to the exposure of the stain samples to the environment. Experiences with degraded DNA from casework samples show that every sample may exhibit different properties in this respect, and that it is difficult to systematically assess the performance of routinely used typing systems for the analysis of degraded DNA samples. Using a batch of artificially degraded DNA with an average fragment size of approx. 200 bp a collaborative exercise was carried out among 38 forensic laboratories from 17 European countries. The results were assessed according to correct allele detection, peak height and balance as well as the occurrence of artefacts. A number of common problems were identified based on these results such as strong peak imbalance in heterozygous genotypes for the larger short tandem repeat (STR) fragments after increased PCR cycle numbers, artefact signals and allelic drop-out. Based on the observations, strategies are discussed to overcome these problems. The strategies include careful balancing of the amount of template DNA and the PCR cycle numbers, the reaction volume and the amount of Taq polymerase. Furthermore, a careful evaluation of the results of the fragment analysis and of automated allele calling is necessary to identify the correct alleles and avoid artefacts.     

论WTO法下的中国法制变化

中国入世后在WTO法的约束下,较快地完成了将WTO法转化为大量国内法的艰巨任务。中国入世所引起的国内法制的直接变化和法治观念的间接变化,不亚于30多年前中国法制的重建。WTO法所包括的协定尚无具有国际法效力的中文本,对于国内实施带来诸多困难,但是,中国依然通过对应式、归纳式和分散式三种国内立法转化WTO法而履行了实施义务,并由此促进了中国法制透明度的增强与法治观念的变化。诚然,就国际法与国内法的关系而言,为了进一步适应WTO法,中国《宪法》的缔约规定亟待修改,WTO法在国内的司法解释应予进一步规范,立法解释与司法解释的关系应予理顺。     

司法成本与司法效率——中国法院的财政保障与法官激励

我国司法改革进程中,法院的财政保障构成了司法成本的主要问题。从长远的观点看应建立中央统一的司法财政与决算制度。此外,为了有效遏制司法腐败和从根本上提高司法公信力,通过渐进和配套的制度改革,将法官从一般公务员系列里独立出来并给予相对高的报酬仍应作为司法改革的一个努力方向。     

网络时代的资本市场及监管法制之重塑

互联网技术正日益渗透于资本市场各个环节,并深刻影响着资本市场的结构和运行模式。网络技术与资本市场的高度融合预示着一个资本市场网络时代的到来,这需要我们重新审视已有的监管理念和监管规则,以更加从容的心态加以应对,改变以简单控制为主的监管思路和监管策略,采取积极引导、强化监管的指导思想,在发挥技术革新优势和有效监管之间积极地寻求平衡,以推动我国资本市场的成功转型。
