We studied and established a database and some parameters of forensic importance were calculated of 16 Y-STR (DYS19, DYS385, DYS389I/II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS460, DYS461, GATA-A10, GATA-H4 and DYS635) in a population of 298 unrelated males of African descent of Chocó (Colombia) and a total of 257 haplotypes were identified using the present set of Y-STR markers, of which 224 were represented only once in the database. Twenty-six haplotypes were presents two times, six haplotypes were presents in three individuals and one haplotype in four men. The haplotype diversity was 0.9987 ± 0.0004. By combining the allelic states of the 16 Y-chromosomal STRs we could construct highly informative haplotypes that allowed the discrimination of 86.2% of the samples tested. With this work we established a database of Y-STR and some parameters of forensic importance. This approach represents a very powerful tool for individual identification and paternity testing in forensic genetic. 相似文献

David Luban identifies a tension between Arendt's conception of ethnic identification in a context of persecution and her conception of humanity. That tension pertains to the reality—or realities—that Arendt addresses: the moral reality of her Bildung that appears throughout her work, and is centered on the “dignity of man,” on the one hand, and the divisive, “political” reality that she was forced to face when “attacked as a Jew,” on the other. By implicitly accepting that in a context of persecution one cannot escape the framing relevance of the “political” —an idea that is also present in her imaginary condemnation speech of Eichmann—Arendt betrays a fundamental theme of her work: “forgiveness” and the inherent possibility of a “new beginning.” 相似文献

This paper describes the gross domestic product and hydrological environment service method for assessing the socio-economic consequences of implementing necessary measures for safeguarding the quality of groundwater for human consumption and eliminating the risk of pollution. This method assesses the positive and negative impacts of designations of protected areas. Economic assets and social goods are the two integrated variables used in analysing the method. The first includes economic impacts on the local gross domestic product of defining protected areas, and the second considers the benefits of this designation in the conservation of water resources, assigning a monetary value to the preserved resources. In addition, tools have been incorporated, such as payment for hydrological services and generation of permissible activities, which reduce negative social impacts through positive economic impacts. These tools can only be used when compliance with conservation requirements for protected areas is demonstrated. The conclusions of this study include an application of the proposed methodology and provide essential and specific assessments that show that this methodology fulfils the requirements of the European Water Framework Directive requirements and that it is an effective tool in the implementation and development of strategies for hydrological planning processes. 相似文献
