二审和解撤诉後当事人反悔，一审法院的判决书能否强制执行

民事二审和解撤诉之後，一方当事人反悔，另一方当事人能否向法院申请强制执行一审判决？中国的《民事诉讼法》和《民诉意见》对此问题并没有规定，实践中法院、当事人、检察院对此问题的处理方式五花八门。笔者以为：一审法院判决效力的认定是解决该类争议的关键。对此，笔者首先厘清了撤回起诉和撤回上诉的区别，然後又从绝对无效和相对无效角度层层推进，最後得出只有双方当事人在和解协议中明确约定反悔後执行一审判决，此时的一审判决才是有效的，其他情况均为无效。     

Rapid direct PCR for ABO blood typing

Many different molecular typing methods have been reported to complement routine serological ABO blood typing in forensics. However, these ABO genotyping methods are often time-consuming and call for an initial DNA isolation step that requires the use of expensive kits or reagents. We report here a rapid direct ABO genotyping method that eliminates the need for DNA extraction from fresh blood, hair, and body fluid stains before PCR. Using a fast PCR instrument and an optimized polymerase, the genotyping method-which employs a multiplex allele-specific primer set for the simultaneous detection of three single-nucleotide polymorphism (SNP) sites (nucleotides 261, 526, and 803)-identifies A, B, O01/O02, O03, and cis-AB01 alleles in around 70 min from sample collection to electropherogram. Not only will this ABO genotyping method be efficiently used in forensic practice for rapid screening of samples before full-blown multilocus short tandem repeat profiling, but it will also demonstrate an example of rapid direct genotyping of SNPs that offers the advantages of time- and cost-efficiency, convenience, and reduced contamination during DNA analysis.     

A Y‐Chromosomal Haplotype with Two Short Tandem Repeat Mutations*

Abstract:  The male‐specific Y‐chromosomal short tandem repeat (STR) is a useful tool in forensic casework. The Y haplotype comprised of 16 loci, which is amplified simultaneously by AmpFlSTR^® Yfiler^TM PCR kit and provides strong exculpatory evidence in individual identification. We reported a rare Y‐STR profile with a null allele at the DYS448 locus and an off‐ladder allele at the DYS456 locus, when genotyping material from a vaginal swab in an alleged rape case. Sequence analysis revealed that the DYS448 null allele was a true type of null allele because of a total deletion of 11 upstream repeats and 9 bp of the N₄₂ region, and there were numerous primer binding site mutations as well. The amplicon of the DYS456 locus was a small 92‐bp fragment that was off‐ladder, and sequencing analysis showed that there were only 10 repeats (AGAT)₁₀. This Y chromosome haplotype that was comprised of two variations provided helpful evidence for personal identification.     

Evaluation of 96 SNPs in 14 populations for worldwide individual identification

Great advances have been made recently in searching for individual identification single-nucleotide polymorphisms (IISNPs or IDSNPs). Such SNPs as suggested by SNPforID scientists and by Pakstis et al., are promising, although they were selected from older or smaller databases rather than the most recent database. Here, we describe a new computational strategy for developing IDSNPs based on HapMap. We searched through HapMap r27 for SNPs having minor allele frequencies ≥0.30 in all its 11 populations and found more than 1881 qualified SNPs. We examined 96 of them with 183 DNA samples from three Chinese populations using Illumina arrays. The average allele frequency for these 96 SNPs among the three populations was 0.495/0.505, the average number of identical SNP genotypes shared by two individuals among the 14 populations (three Chinese and 11 HapMap) was 37.9, and the random matching probability for two unrelated Hans to match in all 96 genotypes was 9.793 × 10(-39). Thus, most of these 96 SNPs are universally applicable.     

PowerPlex^TM16体系OL等位基因序列分析及命名探讨

目的观察中国汉族人群PowerPlexTM16体系STR基因座分型标准物外等位基因(OL等位基因)的序列组成,探讨其类型及命名。方法应用PowerPlexTM16体系和ABI377或3100遗传分析仪,对10071名中国汉族无关个体的血样DNA进行15个STR基因座的分型,筛选出OL等位基因样本;对该样本进行单基因座扩增、聚丙稀酰胺凝胶电泳、银染显色,获取等位基因条带并再次扩增和测序。结果在11个基因座检见OL等位基因,共32个,频率0.05‰￣4.02‰,各基因座OL等位基因数目1￣9个不等。按其组成分为四类:(1)重复单位完整重复,但重复次数在ladder范围外;(2)不完整重复;(3)侧翼序列个别碱基的插入或缺失;(4)较大片断的缺失。结论OL等位基因类型不一,既有重复次数的变化,也有侧翼序列或核心序列的变化,现有命名原则尚不能反映其组成类型。

Protesting with the ballot: Diffusion of methods of electoral protest in Spain

This paper shows the pattern of diffusion of a tool of protest – blank and null voting (BNV)– in the context of Spanish national elections. It shows how the 2004 protest mobilization by Batasuna (a Basque nationalist party) predicts null voting by identifying the relationship of this form of protest with both the level of grievance of the population and the political resources of the mobilizers. The paper then demonstrates that this large and visible use of a protest tactic is followed by a heterogeneous diffusion process after the main mobilized protest event and beyond the supporters of the original mobilizer. In the 2008 national election, across Spain, citizens with grievances toward the political system and, most importantly, with political affinity with the initiators were the ones to update their individual protest repertoire with this electoral protest tool.
