The PowerPlex 16 BIO multiplex short tandem repeat (STR) system contains the 13 CODIS loci (FGA, TPOX, D8S1179, vWA, D18S51, D21S11, TH01, D3S1358, CSF1PO, D16S539, D7S820, D13S317, and DS5S818), plus two pentanucleotide repeat loci (Penta D and Penta E) and the sex-identifying locus. Amelogenin. The PowerPlex 16 BIO System is optimized for use with the Hitachi FMBIO gel imaging systems. A consortium of seven independent laboratories collaborated to perform the studies defined by the FBI standards for performing a developmental validation, including the evaluation of sample concordance, percent stutter determination, nonprobative casework, precision, sensitivity, mixture determination, effect of substrates, the impact of environmental insults, and species specificity. All samples tested for concordance were consistent except for one sample from the Virginia Division of Forensic Science database that displayed discordance at D13S317, a locus whose primer sequence was altered. Stutter values were comparable to those of other STR multiplex systems, the precision was comparable to other multiplexes analyzed by gel electrophoresis, the DNA profiles were unchanged by the substrate upon which the blood samples were placed, and the nonprobative casework samples re-typed for the PowerPlex 16 BIO System were consistent with previous typing results. When greater than 0.125 ng of DNA was placed into the PowerPlex 16 BIO System amplification reaction, a full profile was generated by all laboratories. The mixture study results were comparable to those reported for other multiplex systems, the environmental study demonstrated a loss of larger molecular weight loci when samples were incubated at elevated temperatures for a prolonged period of time, and the only notable cross species hybridization was observed with primate DNA samples. This extensive validation work performed demonstrates that the PowerPlex 16 BIO System provides STR data of a quality comparable with other PowerPlex STR multiplex kits as well as other widely used STR multiplexes and is thus suitable for evidentiary casework analysis as well as database sample profiling. 相似文献

This study examined the impact of the September 11 terrorist attacks on graduate and undergraduate students and the role of optimism in posttraumatic distress. A sample of 457 students who attended courses at three schools of social work (Nevada, Pennsylvania, and Washington) participated in the study. A quarter of them had a known person as an immediate victim of the attacks. Multivariate analysis showed that posttraumatic stress disorder symptom scores were positively related to personal loss and two types of previous trauma reactivated by the attacks, and levels of initial negative emotional response. Optimism and its interaction with personal loss were inversely associated with posttraumatic stress disorder symptom scores. 相似文献

Allele and haplotype frequencies of 17 chromosome STR loci, 15 of them included in the kit PowerPlex 16 System from Promega, were determined in a sample of unrelated males from Madeira and Porto Santo Islands. PowerPlex 16 includes STRs not studied before in the Madeira population. The-kit includes two new allele markers (Penta D and Penta E), which proved to be extremely useful for paternity testing (PD = 0.952 and 0.977, respectively). The study revealed that the Madeira population does not differ from that of the north Portugal. Nevertheless, some loci presented alleles found in sub-Saharan and North European populations which were not reported so far in Portugal. 相似文献

Allele and haplotype frequencies for nine Y-specific STR loci (DYS19, DYS389-I, DYS389-II, DYS390, DYS391, DYS393, DYS434, DYS437, and DYS439) were obtained from a sample of 57 males from Guinea Equatorial. 相似文献

Allele and haplotype frequencies of 16 chromosome STR loci, 15 of them included in the Kit PowerPlex16 System from Promega were determined in a sample of unrelated males from the A?ores Archipelago. All subjects were subjected to an interview in order to make sure that their ancestors belonged to the same island at least back to three generations. This way we intended to look for possible inter-islands differences. PowerPlex16 includes STRs not studied before in the A?ores population. The Kit includes two new allele markers (Penta D and Penta E), which proved to be extremely useful for paternity testing (PD=0.921 and 0.971, respectively). The study revealed that the A?ores population is considerable different from the previous studied Madeira population, but does not differ from that of the north Portugal. Nevertheless, some loci presented alleles not previously reported for Portugal. 相似文献

Stigma as a barrier to employment: mental disability and the Americans with Disabilities Act 总被引:1,自引:0,他引:1
Scheid TL 《International journal of law and psychiatry》2005,28(6):670-690
In a controversial expansion of workplace civil rights, the 1990 Americans with Disability Act (ADA) extended anti-discrimination protection to individuals with "mental impairments." One of the most critical barriers to the employment of individuals with mental disabilities is the degree of social stigma such disabilities incur, and there is compelling evidence that employers have stigmatizing attitudes and have discriminated against those with mental disabilities. This study examines the role played by stigma in employers' response to the 1990 Americans with Disability Act (ADA). A stratified sample of one hundred ninety employers were surveyed in 1996-1997 in a major Southern metropolitan area. Telephone interviews were completed with one hundred seventeen employers (response rate of 61.6%). The article describes employers' experiences with employees with mental disabilities and accommodations, specific employment practices, and attitudes towards those with mental disabilities. Stigma played an important role in conformity to the ADA (operationalized as either hiring or having specific recruiting policies for hiring individuals with mental disabilities). Furthermore, employers expressing coercive (fear of a lawsuit) as opposed to normative (belief that it is the right thing to do) rationales for compliance were more likely to hold stigmatized attitudes. Employers' beliefs about mental disability form a crucial foundation for truly supportive work environments (those that value difference and diversity), and further research is needed to determine if over time the ADA is successful in changing attitudes as well as behavior. 相似文献

Positive psychologists found the increase of seven character strengths that encompass the so-called theological virtues, including hope and spirituality, in Americans after the September 11, 2001, attacks. Little is known about how they may affect post-September 11, 2001, mental health. Using multivariate analysis, this study investigated the relationship of hope and spiritual meaning with depression and anxiety in a sample of 457 students 3 months after September 11, 2001. Both characters contributed to lower levels of symptoms. In qualitative analysis, of 313 answers to an open-ended question regarding personal change, four categories emerged. The first three were consonant with other studies on posttraumatic growth (PTG), including changes in the self or behavior, relationships, and worldviews. The fourth category unique to September 11, 2001, was changes in political views. These findings offer further credence to the study of positive aspects resulting from violence-related trauma and highlight the needs for addressing the nature of traumatic events and PTG. 相似文献
