Improvements in detection limits/sensitivity and lower sample consumption are potential benefits of reducing PCR reaction volumes used in forensic DNA typing of crime scene samples. This premise was studied first with experimental mixtures and a nine-loci megaplex, which demonstrated stochiometric amplification and accurate detection. Next, adjudicated casework samples were subjected to amplification under 15 different template DNA to PCR reaction volume ratios. Reduction of PCR reaction volume and DNA down to 10 microL and 0.500 ng, respectively, produced identical profiles with the same signal intensity and heterozygous allele peak height ratio (HR). Reduction to 5 microL and 0.063 ng yielded HR values that were slightly affected in one to three STR loci. PCR reaction volume reduction can enhance detection and sensitivity while reducing the consumption of irreplaceable crime scene samples. 相似文献

In this article, we identify legal knowledge as a key difference between workers who desire workplace change and those who do not. Based on surveys with 121 day laborers, we find that not all day laborers are equally dissatisfied with their jobs, despite uniformly difficult working conditions. Some day laborers do not want to make any real changes to the day labor industry, while others desire a range of industry changes, from higher wages to greater government regulation and unionization. A key difference between these workers is their knowledge of employment law: Those who know the law are more likely to desire workplace change. 相似文献

At least one‐quarter of covered workplaces violated the parental leave requirements of the Family and Medical Leave Act of 1993 (FMLA) when surveyed in 1997. What explains this noncompliance? Using a survey of 389 U.S. workplaces and qualitative interviews with managers in 40 organizations, I demonstrate that noncompliance comes in distinct forms. Some forms of noncompliance result from a failure to update institutionalized—and gendered—policies, practices, and norms. This form of noncompliance (indicated by illegally short leaves) is better explained by the institutional perspective, while outright noncompliance (as evidenced by a lack of leaves) is best explained by rational choice and deviant culture theories. 相似文献

IMPLEMENTING COMPARABLE WORTH IN THE PUBLIC SECTOR: THEORY AND PRACTICE AT THE STATE AND LOCAL LEVEL
This paper defines comparable worth as part of the pay equity movement, given an overview of the reasons for its development in the 1980s.and identifies objections to its implementation. It also articulates the political and implementation challenges comparable worth presents and specifies the purpose of this special symposium. 相似文献

We measured stable hydrogen isotope ratios in the primary feathers of two subspecies of goldfinches, confiscated by the Police and the Royal Society for the Prevention of Cruelty to Animals (RSPCA) on suspicion that they had been illegally taken from the wild. We found significant differences in the delta2H values of the two subspecies indicating that they were sourced from different geographical regions. Our results correlated with isotopic precipitation maps and with the known distribution of the two subspecies of goldfinch. We believe that this technique could be used by law enforcement agencies to determine the origin of birds in cases where the species or subspecies involved are geographically distinct. 相似文献
