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 article examines the relation among gender, social-emotional adjustment, and deviant behavior among serious juvenile offenders. A sample of 105 adolescent offenders completed questionnaires assessing social-emotional characteristics and self-reported involvement in deviant behaviors. Results indicate significant associations between distress and restraint in predicting deviance, a finding that was invariant across gender. Analysis of four distinct social-emotional profiles found that membership in the reactive group was associated with the greatest amount of deviant behavior. Results also indicate that not only do serious offending girls internalize more than serious offending boys, they appear equally likely to externalize. However, although boys exhibit less distress than girls, those boys who report high rates of deviance may exhibit internalizing and externalizing problems similar to girls. The use of social-emotional measures in general, and distinct profiles in particular, may aid in targeting specific programming and treatment in an effort to provide offenders with more effective interventions. 相似文献

Recent experimental evaluations have suggested little or no effect of batterer programs on reassault but are compromised by methodological and analytical issues. This study assesses program effect using propensity score analysis with a quasi-experimental sample in an attempt to address these issues. The sample consisted of 633 batterers and their partners from three geographically dispersed batterer programs and a 15-month follow-up with their female partners. Subclassification on propensity scores was used to balance program completers and program dropouts. The propensity score was estimated as the probability of completing the batterer program conditional on observable characteristics. Direct adjustment indicates that program completion reduced the probability of reassault during the 15-month follow-up by 33% for the full sample, and by nearly 50% for the court-ordered men. 相似文献

Grounded in Stephen Skowronek's typology of presidential leadership, this paper furthers our understanding of 'pre-emptive leadership' through a comparative analysis of the welfare and Social Security reforms pursued by US presidents Richard Nixon and Bill Clinton. Although not identical, their experience in these areas provides valuable insight into the difficulty of wielding power in an inhospitable political environment. The paper starts with a brief presentation of Skowronek's typology before discussing the electoral strategies employed by both presidents as they attempted to frame political identities that would allow them to compete successfully in unfavourable ideological and political circumstances. The paper then specifically focuses on the politics of welfare and Social Security reform as the two presidents used these issues as part of their efforts to craft distinctive political images and attract wider electoral support. This comparative analysis reinforces the concept of 'pre-emption' as a valuable tool in understanding presidential behaviour. However, it also underlines the limits of pre-emptive leadership. Pre-emptive strategies can be effective at election time, but they are less likely to succeed in the legislative arena. This reality complicates the presidential search for genuine policy legacies. 相似文献

This article examines four accepted wisdoms about HIV/AIDS andAfrican armies and in each case concludes that substantial revisionis necessary in the light of emerging evidence. First, it appearsthat military populations do not necessarily have a higher prevalenceof HIV than civilian populations. HIV levels in armies dependon many factors including the demographics of the army, itspattern of deployment, the nature and stage of the epidemicin the country concerned, and the measures taken to controlthe disease by the military authorities. Second, although theepidemic has the potential to undermine the functioning of nationalmilitaries, and may have done so in isolated instances, armiesin general are well placed to withstand the threat. Third, evidencethat war contributes to the spread of the virus is meagre andsuggests that we should be concerned primarily with specificrisks that conflict may entail including population mobilityand changing sexual networks. Lastly, the hypothesis that AIDShas the potential to disrupt national, regional, and internationalsecurity remains speculative.
