论交通肇事犯罪人的特点及刑事责任

交通肇事犯罪人属于一般自然人主体,具有与传统犯罪人不同的性格特征,交通肇事犯罪人在主观上是过失心态。行为人交通肇事后逃逸是我国刑法规定的加重处罚情形,交通肇事犯罪人的共犯是我国刑法规定的特殊处罚情形,交通肇事后行为人遗弃被害人的,应当按故意杀人罪或故意伤害罪处罚。应当从刑事立法、刑事政策、犯罪学理论三方面入手,加强对交通肇事犯罪人的预防和惩处,有效防止交通肇事罪的发生。     

Genetic polymorphism of 17 STR loci for forensic use in Chinese population from Shanghai in East China

Allele frequencies for 17 STR loci found in Identifier kit and PowerPlex^®16 Monoplex System were determined in a sample of 1000 unrelated individuals living in Shanghai in East China. The values of observed heterozygosity (Ho), power of discrimination (PD), probability of paternity exclusion (PE) and polymorphism information content (PIC) were calculated. All loci were in accordance with Hardy–Weinberg equilibrium (p < 0.05). The obtained frequency distributions were compared with other previously reported population data.     

ABO genotyping by duplex amplification and oligonucleotide arrays assay

Objective

Research on the application feasibility of ABO genotyping for forensic identification by oligonucleotide arrays assay.

Methods

Oligonucleotide microarrays which detect three different SNPs in exon 6 and exon 7 for ABO genotyping were used. After hybridization wash, the arrays were scanned and fluorescence intensities were analyzed using microarray population studies on ABO was carried out in a sample of 115 unrelated Chinese Han individuals oligonucleotide arrays for genotype detection. The method was also applied to cases.

Results

Technique could identify six genotypes of ABO system and the results of GeneChip analyses confirmed by PCR–RFLP. According to the results of population studies, no significant deviations Hardy–Weinberg equilibrium could be found. The observed heterozygosity (H-obs) was 0.591. Expected heterozygosity (H-exp) was 0.616. The polymorphic information content (PIC) was the average exclusion probability in paternity testing for duos (PE (1)) was 0.188. The average exclusion probability in paternity testing for trios (PE(2)) was 0.344. The discrimination power 0.777.

Conclusion

The data and case application demonstrated that ABO typing by oligonucleotide probe arrays was a useful technique for paternity testing and individual identification.     

对实用艺术作品著作权保护之法律探析——完善我国《著作权法》立法建议

我国《著作权法》及《著作权法实施条例》中,对实用艺术作品均没有任何明确的规定,实用艺术作品的法律保护至今仍为空白。我国应结合国际公约、条约和国外一些国家的法律规定,在《著作权法》中应明确规定对实用艺术作品的著作权保护的具体措施。     

收费权质押法律问题辨析

当前,我国银行越来越多地开展以各种收费权为质押担保的融资业务,但包括新近出台的《物权法》在内的相关法律法规均未对收费权质押作出明确而系统的规定,导致收费权质押这种担保方式面临诸多法律风险。在对我国现有收费权质押相关法规作梳理总结的基础上,重点探讨收费权质押的法律特征,有助于理清收费权质押的独立价值,并进而提出相关立法建议。

Haplotype of 12 Y-STR loci of the PowerPlex Y-system in Sichuan Han ethnic group in west China

Haplotypes and allele frequencies for 12 Y-STR loci were determined in Sichuan Han ethnic population samples of 237 unrelated males living in west China. Only one haplotype was encountered in triple. Twelve of the haplotypes were encountered in duplicate, while 210 haplotypes were unique. The gene diversity was 0.9952. This study provides an essential precondition for identification of male DNA and tracing of paternal lineages.     

Genetic analysis of 17 Y-chromosomal STRs haplotypes of Chinese Tibetan ethnic group residing in Qinghai province of China

We have co-amplified and analyzed 17 Y-chromosomal STRs loci including European 'extended haplotypes' (DYS19, DYS389 I, DYS389 II, DYS390, DYS391, DYS392, DYS393, DYS385a,b, DYS438, and DYS439) and also six additional loci DYS437, DYS448, DYS456, DYS458, DYS635 and YGATA H4 in a population sample of 167 healthy unrelated autochthonous male individuals of Chinese Tibetan ethnic minority group residing in Qinghai province of China using a multiplex PCR system. The gene diversity values for the Y-STRs loci ranged from a minimum 0.3581 for DYS391 locus to a maximum of 0.8702 for DYS385a,b loci in Tibetan population. A total of 163 haplotypes were identified in the set of Y-STR loci, of which 159 were unique and 4 found in two individuals. The overall haplotype diversity for the set of Y-STRs loci was 0.9998, and the discrimination capacity was 0.9938. Research results will be valuable for human identification and paternity tests in the region and for Chinese population genetic study in the future.
