This is another in a series of technical articles describing Social Security Administration sample files and statistical systems. The focus of this article is the 10-percent sample file that provides program and demographic information on Social Security beneficiaries under the Old-Age, Survivors, and Disability Insurance program. The article explains the contents and availability of the 10-percent sample and presents several statistical tabulations as examples of the wide variety of data that can be developed from the file. 相似文献

This article employs the concept of rhetorical action in an analysis of the recent developments in Czech-Russian political relations. Through the discourse analysis of key Russian political speeches and official documents related to the Czech Republic, as well as Czech speeches tackling the same issues, we look at two different rhetorical actions employed by Russia to induce changes in Czech policy. The attempts to make Czech policy unacceptable in the wider community of European democracies were only partially successful. While the first rhetorical action aimed against Czech NATO membership failed, the new diplomatic strategy stressing the need for a “normalization” of relations was successful in transforming Czech policy towards Russia. 相似文献

During February and March 2000, human remains were recovered from the Holy Loch, Scotland. Police enquiries identified 13 males that had gone missing, presumed drowned in the Holy Loch or the adjoining lochs, over the previous 35 years. Osteological examination of the remains established they were from a male, aged between 15 and 23 and 168-174 cm tall. This information eliminated ten of the known missing persons. DNA profiles, both STR and mitochondrial were generated from the remains and compared to the profiles generated from relatives of the missing men. A positive match between the unidentified individual and one of the maternal relatives identified the remains as belonging to a US serviceman who had gone missing 35 years ago. The successful identification led to the repatriation of the serviceman's remains. 相似文献
