Applying the 16 Y-chromosome STRs in the population of central Poland

Haplotype and allele frequencies for the panel of 16 Y-chromosome STR loci, namely DYS19, DYS385, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635 and Y GATA-H4 were determined in a population sample of 200 unrelated males from the central region of Poland. The 191 different haplotypes were identified, of which 182 haplotypes were unique and 9 were duplicated. None of observed haplotypes appears more than twice in the investigated population. The haplotype discrimination capacity was 0.955, and combined gene diversity was 0.9999. The analysed set of 16 Y-STRs is very useful in forensic practise to identify males and trace paternal lineages.     

Autosomal microsatellite data from Northwestern Colombia

Allele frequencies and some forensic parameters for 12 autosomal microsatellites (CSF1PO, TPOX, THO1, VWA, D16S539, D7S820, D13S317, D5S818, F13A1, FESFPS, F13B, LPL) were estimated from three departments from Northwestern Colombia. The total number of samples analysed was 1045 individuals.Comparative analysis among the three studied departments and with other published Colombian populations were also performed and discussed.     

The Knowledge-Based Economy: Conceptual Framework or Buzzword?

In the last two decades, concepts have appeared that have influenced and even defined entire science and technology policies in Western countries: high technology, national system of innovation, information economy, knowledge-based economy, and the new economy. In all these policy developments, the OECD, acting as a think tank for its member countries, has been an important promoter of these concepts, turning them into buzzwords. This article looks at the concept of knowledge-based economy in order to explore the crucial role of the OECD in its dissemination and, above all, the role statistics have played in shaping policy discourses.     

试论人口萎缩对国家安全的影响

从国家安全的角度来看,一个国家必须保持一个适度的人口规模,不仅是因为民族及文化得以延续的需要,也是正常进行社会分工的最起码的条件。而人口的过度萎缩会给工业国家带来国家和民族的“集体自杀”、人口的过度老龄化以及民族结构的改变等对国家安全的不利影响。对中国而言,适度的人口萎缩并不会对中国的文化和种族的延续构成威胁,反而有利于缓解在资源和环境方面所承受的巨大压力,但是过快、过急的人口萎缩会改变中国合理的人口结构,从而引发社会、经济和政治问题,并对国家安全构成威胁。     

Population data of Y-chromosomal STRs in lithuanian, latvian and estonian males

Data of nine Y-chromosomal STRs, the so called “extended core set”, were obtained from 152 unrelated males from Lithuania, 145 from Latvia and 133 from Estonia. The haplotype data reported here have been included into the Y-STR database maintained at the Institute of Legal Medicine, Humboldt-University, Berlin.     

基于相对资源承载力的广东省区域人口问题研究

相对资源人口承载力的测算,能够比较科学地分析研究区相对于参照区的人口发展状态,为研究区制定人口战略、政策提供参考。对相对资源人口承载力测算模型进行改进,引入相对资源人口承载压力指数。选取1997-2007年广东省及21个地级以上区域相对资源人口承载力数据,运用改进后的相对资源人口承载力几何模型和优化的指标,对广东省21个地级以上区域相对资源人口承载力进行分析。结果显示,对于相对资源人口承载力及承载压力的测算,指标匹配的全面性、复合性、协调性,模型的客观程度决定测算的科学与否。广东省21个地级以上区域,人口承载压力总体比较大,珠三角、东翼多数区域人口承载压力呈增大趋势;西翼、粤北山区人口承载压力呈减弱趋势;除广州外,其它区域人口承载压力,相对广东远小于相对全国。     

当前户籍制度改革面临的难点与动力基础分析

近年来,要求改革户籍制度的呼声不断。户籍制度改革面临的难点:1.从资源分配上,统一城乡户口并不意味着相关社会问题会随之解决;2.对于大城市户籍改革成本的认识难以统一;3.统一城乡户口意味着流动的双向性。动力基础:1.城市拉力不断提升;2.农村推力经济的持续发展;3.实现比较利润的平衡化。     

Human Y-specific STR haplotypes in a Slovenian population sample

The allele distribution of the systems DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385 and YCAII were investigated in a sample of 121 unrelated males from Slovenia     

Progress Toward the Determination of Correct Classification Rates in Fire Debris Analysis,,

Principal components analysis (PCA), linear discriminant analysis (LDA), and quadratic discriminant analysis (QDA) were used to develop a multistep classification procedure for determining the presence of ignitable liquid residue in fire debris and assigning any ignitable liquid residue present into the classes defined under the American Society for Testing and Materials (ASTM) E 1618‐10 standard method. A multistep classification procedure was tested by cross‐validation based on model data sets comprised of the time‐averaged mass spectra (also referred to as total ion spectra) of commercial ignitable liquids and pyrolysis products from common building materials and household furnishings (referred to simply as substrates). Fire debris samples from laboratory‐scale and field test burns were also used to test the model. The optimal model's true‐positive rate was 81.3% for cross‐validation samples and 70.9% for fire debris samples. The false‐positive rate was 9.9% for cross‐validation samples and 8.9% for fire debris samples.
