Y chromosome STR haplotypes of Tibetan Living Tibet Lassa

Allele frequencies and haplotypes of the 17 Y-chromosome STRs loci, namely DYS19, DYS385a/b, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635 (YGATA C4), and YGATA H4 were determined in a sample of 131 healthy unrelated males from the Lassa area of Tibet Autonomy Region of China (SW China). In 131 samples 106 different haplotypes were encountered, of which 105 were observed only once. The overall haplotype diversity was 0.9998. The results demonstrate that these loci will be very useful for human identification in forensic cases and paternity tests in the Lassa region.     

Y-chromosomal haplotypes for the AmpFlSTR Yfiler PCR Amplification Kit in a population sample from Central Poland

Haplotype and allele frequencies for 17 Y-STR loci (DYS456, DYS389I/II, DYS390, DYS458, DYS19, DYS385 I/II, Y GATA H4, DYS437, DYS438, DYS448, DYS393, DYS391, DYS439, Y GATA C4, DYS392) were determined in 255 unrelated males from central Poland using AmpFlSTR Yfiler PCR Amplification Kit. Two hundred and fifty-two different haplotypes were observed. The most common three haplotypes were shared by 0.8% of the sample, respectively. Two hundred and forty-nine haplotypes were encountered only once.     

人口出生性别比例问题研究

人口性别比例,关系人口安全乃至国家安全。人口普查资料显示,我国人口出生性别比已高达117,偏离正常标准10个百分点,其危害不仅涉及眼前,甚至会危及子孙。政府部门在矫正人口出生性别比方面要在制度安排、政策扶持、监管惩处方面综合治理,单凭宣传教育是不够的。     

从“两个实有”金覆盖管理工作谈政府实施人口综合服务和管理的对策——以上海市虹口区为例

上海市虹口区推行的“实有人口、实有房屋”全覆盖管理工作取得了较好的实效。为了加强上海市的人口综合服务与管理工作。相关职能部门应当进一步完善管理体系、建立评估机制、健全法律法规、加强社区综合协管队伍建设与完善数据库维护机制等。     

延边朝鲜族人口发展现状及民族教育对策

学习型组织理论问世以来,首先在企业管理中取得长足进展,继之被引入以政府机构为代表的组织管理过程。在步入新世纪的时刻,随着教育改革的不断深入,走向学习型组织将成为学校组织的必然选择。     

21世纪西欧国家养老金改革述评

近些年来,西欧各国纷纷进行养老金改革以缓解人口老龄化所可能带来的公共养老金体系的可持续性危机。中国与西欧国家在人口老龄化趋势上面临着类似的压力,本文从老龄经济的视角,以德国、法国、英国三个拥有不同模式养老金体系的国家为研究对象,详细介绍上述三国新世纪养老金体系改革的具体措施,分析改革的共同趋势;并展望中国未来养老金体系的发展方向,认为,以税收优惠和灵活制度安排鼓励第二和第三养老保障支柱的发展是德法英三国改革的共同趋势,也是中国未来养老金体系发展的重要方向。     

当前加强外来人口管理的探索与实践

在法制日益完善的新形势下,必须改变外来人口的传统管理模式。开辟租赁房屋市场化管理的新途径;用足法律,强化外来人口的“人头”管理;查询比对,掌握控制外来“高危人群”;各司其责,协调配合,落实对外来流浪乞讨人员的救助管理。     

Microgeographic variation of Y-chromosome haplotypes in Italy

Within an Italian collaborative exercise on the extended haplotype of the Y-chromosome, 1288 subjects were typed by the AmpFlSTR YFiler Amplification Kit (AB Applied Biosystems) and other 526 were typed by the PowerPlex Y^® System (Promega). The sampling scheme included either a “regional” or a “local” recruitment, the first referring to individuals born in the region of the participating lab, the second referring to individuals coming from small villages. Total sample sizes were N = 954 and 860, respectively. A significant decrease of haplotype diversity was found in the local samples. The results may be of interest in forensic applications of the Y-chromosome.     

Analysis of 8 Y-chromosome str loci in population from alicante (Spain)

The allelic frequencies and the haplotype distribution were studied in 8 Y-chromosome STR loci: DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, and DYS 385. Data was obtained from 104 unrelated autochthonous subjects from the province of Alicante, located in the Southeast of Spain. The obtained data will contribute to further progress in the studies on chromosome Y in Spain.     

Microgeographic genetic variation of Y chromosome in a population sample of Ravenna's area in the Emilia-Romagna region (North of Italy)

The analysis of the genetic structure of regions with a complex demographic history shed light on the various topographic, linguistic and historical influences which form the present genetic landscape of Europe. In the Emilia-Romagna region (North of Italy) Ravenna is a geographical area with a historical complex background: it was an important seaport on the Mediterranean sea, the capital of the Ostrogothic kingdom of Italy and the seat of the Byzantine governor of Italy. The purpose of this study was to investigate the microgeographic variation of Y chromosome haplotypes of the area of Ravenna by analyzing 17 Y-chromosome short tandem repeats (Y-STRs) in 122 unrelated males. 100% of all haplotypes were different. A comparison with neighbouring Italian as well as with European and Levante root populations was done by AMOVA and visualized by a phylogenetic tree. The two main haplogroups found in this area were R1b and E3b1. The results of the present study add to the data for the forensic databases and can be useful also for anthropological studies.
