基于安全视角的上海人口发展问题研究

人口安全是关系到人口自身发展的关键问题,也是城市安全的重要基础。上海建成国际化大都市的发展目标,决定了人口安全管理必须纳入整个城市的发展规划。本文立足于上海人口发展的现实状况,对上海人口安全的影响要素及当前和未来发展过程中存在的突出人口安全隐患进行了系统分析,并在此基础上提出了相应的对策建议。     

STR data for the AmpFℓSTR Identifiler loci from Swedish population in comparison to European, as well as with non-European population

The modern Swedish population is a mixture of people that originate from different parts of the world. This is also the truth for the clients participating in the paternity cases investigated at the department. Calculations based on a Swedish frequency database only, could give us overestimated figures of probability and power of exclusion in cases including clients with a genetic background other than Swedish. Here, we describe allele frequencies regarding the markers in the Identifiler-kit. We have compared three sets of population samples; Swedish, European and non-European to investigate how these three groups of population samples differ. Also, all three population sets were compared to data reported from other European and non-European populations.Swedish allele frequencies for the 15 autosomal STRs included in the Identifiler kit were obtained from unrelated blood donors with Swedish names. The European and non-European frequencies were based on DNA-profiles of alleged fathers from our paternity cases in 2005 and 2006.     

赢多输少还是输多赢少?——WTO争端解决机制申诉方败诉案件解析

利用WTO争端解决机制处理的国际贸易纠纷中申诉方完全败诉的案件占专家组处理案件的10%强,主要原因是申诉方未能完成举证义务,申诉方没有正确提出诉请,被申诉方政府的声明使得专家组不支持诉请。     

Allele frequencies of six miniSTR loci in the population of Northern Portugal

A possible approach to try to recover information from degraded DNA is to reduce the size of the PCR products by designing primers that bind as close as possible to the STR repeat region, known as miniSTRs. Allele frequencies and forensic parameters for the six miniSTRs loci D1S1677, D2S441, D4S2364, D10S1248, D14S1434 and D22S1045 were investigated in a sample group consisting of 228 anonymous apparently healthy unrelated individuals living in North of Portugal. The results show that all loci were in Hardy–Weinberg equilibrium. The combined power of discrimination and power of exclusion for the six loci were 0.99999 and 0.9789, respectively. All but one (D4S2364) loci showed a moderate degree of polymorphism (observed heterozygosity >0.6). The allele sizes ranged between 66 and 118 bp in our population, which is beneficial for typing degraded samples than those of a commercial STR kit.     

天津市人口迁移情况的研究与思考

迁移加速是本世纪前半叶我国人口变动的突出特征。从迁移总量、迁移人口的自然构成和社会构成、迁移原因及迁入人口的来源等研究天津市的人口迁移状况,对于揭示天津人口流动规律、资源配置效果、社会管理水平等有积极的现实意义。     

Analysis of forensically used autosomal short tandem repeat markers in Polish and neighboring populations

The purpose of this study was to evaluate the homogeneity of Polish populations with respect to STRs chosen as core markers of the Polish Forensic National DNA Intelligence Database, and to provide reference allele frequencies and to explore the genetic interrelationship between Poland and neighboring countries. The allele frequency distribution of 10 STRs included in the SGMplus kit was analyzed among 2176 unrelated individuals from 6 regional Polish populations and among 4321 individuals from Germany (three samples), Austria, The Netherlands, Sweden, Czech Republic, Slovakia, Belarus, Ukraine and the Russian Federation (six samples). The statistical approach consisted of AMOVA, calculation of pairwise Rst values and analysis by multidimensional scaling. We found homogeneity of present day Poland and consistent differences between Polish and German populations which contrasted with relative similarities between Russian and German populations. These discrepancies between genetic and geographic distances were confirmed by analysis of an independent data set on Y chromosome STRs. Migrations of Goths, Viking influences, German settlements in the region of Volga river and/or forced population resettlements and other events related to World War II are the historic events which might have caused these finding.     

A database of mitochondrial DNA hypervariable regions I and II sequences of individuals from Slovakia

In order to identify polymorphic positions and to determine their frequencies and the frequency of haplotypes in the human mitochondrial control region, two hypervariable regions (HV1 and HV2) of the mitochondrial DNA (mtDNA) of 374 unrelated individuals from Slovakia were amplified and sequenced. Sequence comparison led to the identification of 284 mitochondrial lineages as defined by 163 variable sites. Genetic diversity (GD) was estimated at 0.997 and the probability of two randomly selected individuals from population having identical mtDNA types (random match probability, RMP) for the both regions is 0.60%.     

把握迁移机理拓展出入境管理空间

人口的变动和社会生产方式的变革是造成人口迁移的根本原因.制约迁移有宏观、中观和微观三层次机制.目前,我国的人口国际迁移存在相对优势和不足.所以,要创建更佳的宏观经济、社会和人文环境;完善人才政策和法规,提高系统性、权威性,确立人才的法制环境;转变体制,创新机制,营造良好的施才环境.     

Applications and extensions of subpopulation theory: a caseworkers guide

This paper extends the calculation of conditional probabilities from those given by Balding and Nichols to casework situations where a series of possible DNA types are possible. Such situations may occur when a sample is identified containing a mixture of DNA from two or more people or where extra information can be determined about the subpopulation under consideration by analysis of additional samples. Using this approach, the error in the estimated likelihood ratios is expected to reduce as the number of additional individuals typed from the subpopulation increases.
