The probative value of animal forensic genetic evidence relies on laboratory accuracy and reliability. Inter-laboratory comparisons allow laboratories to evaluate their performance on specific tests and analyses and to continue to monitor their output. The International Society for Animal Genetics (ISAG) administered animal forensic comparison tests (AFCTs) in 2016 and 2018 to assess the limitations and capabilities of laboratories offering forensic identification, parentage and species determination services. The AFCTs revealed that analyses of low DNA template concentrations (≤300 pg/µL) constitute a significant challenge that has prevented many laboratories from reporting correct identification and parentage results. Moreover, a lack of familiarity with species testing protocols, interpretation guidelines and representative databases prevented over a quarter of the participating laboratories from submitting correct species determination results. Several laboratories showed improvement in their genotyping accuracy over time. However, the use of forensically validated standards, such as a standard forensic short tandem repeat (STR) kit, preferably with an allelic ladder, and stricter guidelines for STR typing, may have prevented some common issues from occurring, such as genotyping inaccuracies, missing data, elevated stutter products and loading errors. The AFCTs underscore the importance of conducting routine forensic comparison tests to allow laboratories to compare results from each other. Laboratories should keep improving their scientific and technical capabilities and continuously evaluate their personnel’s proficiency in critical techniques such as low copy number (LCN) analysis and species testing. Although this is the first time that the ISAG has conducted comparison tests for forensic testing, findings from these AFCTs may serve as the foundation for continuous improvements of the overall quality of animal forensic genetic testing. 相似文献

In this article the authors investigate the impact of the choice of time series method, the length of the data stream used to estimate the model, and the frequency of the data on forecasting accuracy for own source, non-tax general fund revenue for six Connecticut municipalities. The authors find that exponential smoothing models are generally the most accurate. They also conclude that local government officials should rely on bimonthly rather than monthly or quarterly data and retain, in a readily usable format, more than three years of data. 相似文献

The 15 AmpFlSTR Identifiler loci D8S1179, D21S11, D7S820, CSF1PO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, vWA, TPOX, D18S51, D5S818 and FGA were analyzed in a sample of 378 unrelated individuals from Mexico City, Mexico. Significant deviations from HW equilibrium in 14/15 STR loci alleles were not detected. The D18S51 locus had the highest power of discrimination (0.970). Genetic admixture estimations revealed a 69% of Amerindian, 26% of European and 5% of African contribution. Comparative analyses between Mexicans and other neighboring populations reveal significant differences in genetic diversity. Our results are important for future comparative genetic studies in different Latin American ethnic groups, particularly Mexican Mestizos and Amerindians. They should also be helpful in genetics, population evolution, forensic and paternity testing. 相似文献

A total of 272 males from Greenland were typed for 11 Y-chromosome STRs DYS19, DYS385a/b, DYS389-I, DYS389-II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438 and DYS439 with the PowerPlex® Y System (Promega). A total of 146 different haplotypes were observed and the haplotype diversity was 0.9887. The number of haplotypes seen once was 108 and the most common haplotype was observed in 12 males. A significant FST value was observed (FST = 0.012, P < 0.00001) when comparing the population of 15 locations in Greenland assigned to 7 groups. The significance could mainly be attributed to the subpopulation of males from Tasiilaq (East of Greenland). The RST value was not statistically significant (RST = 0.016, P = 0.15). 相似文献

National-anthem-related protests among NFL players have revealed complexities associated with symbolic counter-speech tied to American symbols of patriotism. For public-college officials and coaches, who are bound by the First Amendment, the handling of game-time anthem protests may reverberate beyond the court of public opinion. Because uniformed collegiate student-athletes occupy a constitutional limbo-land in which they are distinguishable both from members of the general adult population and their non-athlete student peers, the traditional framework for evaluating limits on their game-time political counter-speech may prove unwieldy. This article presents an alternative constitutional-analytical approach that contemplates the unique status of collegiate student-athletes and the nature of competitive teams. Within this potential framework, administrator-imposed limits on anthem protests would be reviewed strictly. Courts considering coach-imposed limits on anthem protests, however, might opt for a less rigid form of review that allows for a more direct balancing of interests. 相似文献
