The statistical correlation between the chance of paternity exclusion and paternity index is explored to derive a new criterion of judging the efficiency of an array of genetic determinations for parentage diagnosis. The theoretical basis is illustrated with allele frequency data on genetic markers used in a paternity testing protocol to examine the possible effects of changing the genetic systems on the prospect of identifying fathers by genetic markers. 相似文献

DNA-based analysis is integral to missing person identification cases. When direct references are not available, indirect relative references can be used to identify missing persons by kinship analysis. Generally, more reference relatives render greater accuracy of identification. However, it is costly to type multiple references. Thus, at times, decisions may need to be made on which relatives to type. In this study, pedigrees for 37 common reference scenarios with 13 CODIS STRs were simulated to rank the information content of different combinations of relatives. The results confirm that first-order relatives (parents and fullsibs) are the most preferred relatives to identify missing persons; fullsibs are also informative. Less genetic dependence between references provides a higher on average likelihood ratio. Distant relatives may not be helpful solely by autosomal markers. But lineage-based Y chromosome and mitochondrial DNA markers can increase the likelihood ratio or serve as filters to exclude putative relationships. 相似文献

This work describes the statistical features of a database for two Brazilian populations (one from the Rio de Janeiro State (southeast region), and one from the Mato Grosso do Sul State (central western region) using fourteen short tandem repeat loci (STR). 相似文献

The Y-PLEX 6 and Y-PLEX 5 systems enable analysis for 11 Y-STR loci. We present here the utility of these systems in forensic casework. A total of 188 samples, including 127 evidence samples, were analyzed using either or both of the systems. The evidence sample types included fingernail scrapings, sperm or seminal fluid, epithelial cells, blood and other tissues. The Y-STR typing systems provided useful probative results in difficult cases. A reference database for Caucasian (n = 517), African American (n = 535), and Hispanic (n = 245) population groups within the United States was generated for estimating the haplotype frequency in forensic casework. Among the individuals profiled, 311 Caucasians, 412 African Americans, and 194 Hispanics provided unique profiles in their respective population datasets. This is the first report describing the haplotype database for the set of 11 Y-STR loci recommended by the Scientific Working Group on DNA Analysis Methods (SWGDAM). Linkage analysis reveals that the frequencies from forensically important autosomal loci can be multiplied with the Y-STR haplotype frequency. The results from Y-PLEX systems have been accepted in courts in the United States. 相似文献

Agriculture in the Himalayas has witnessed dynamic shifts and acute crises over the last decade. This viewpoint identifies and discusses the factors leading to de-agrarianisation and land abandonment in the western Himalayas. Data on farming preferences and bottlenecks for agricultural production were also gathered through a short survey with farmers. Escalating male out-migration, land fragmentation and heightened exposure to uncertain environmental conditions have transformed agriculture into a liability for the farmers. The viewpoint suggests that effective implementation of land consolidation reforms in the region would enhance agricultural production, curtail mass migration, and potentially insulate farmers from the ongoing agrarian crisis. 相似文献

Trade and investment are crucial drivers of economic growth. Successful execution of trade and investment policy can elevate a developing country to a sustained growth path and make it self-reliant. Bangladesh implemented a trade liberalization policy in the 1980s, deviating much from its conservative trade policy. This article assesses the impacts of trade, investment in physical as well as human capital, and a few trade policy variables on income surge for the liberalized regime. The econometric analysis finds that export, import, and domestic investment stimulate income. The impact of foreign investment is not conducive. Public spending on education also contributes to the income surge. Among the policy variables, trade openness and currency depreciation produce a beneficial impact. Population growth retards economic growth. The baseline results hold in the estimations involving several specifications of variables and testified as robust. The article views that a comprehensive approach to trade and investment policy would ensure the comparative advantage of trade and the well-being of Bangladesh. 相似文献
