Laboratory procedures used in short tandem repeat (STR) analysis were subjected to various scenarios that assessed reliability and identified potential limitations. These validation studies were designed as recommended by the Technical Working Group on DNA Analysis Methods (TWGDAM) and the DNA Advisory Board (DAB) (17,18). Various DNA samples were amplified by the polymerase chain reaction (PCR) using AmpFlSTR PCR Amplification Kits (i.e., AmpFlSTR Green I, Profiler, Profiler Plus, and COfiler kits), detected with ABI Prism instrumentation, and analyzed using GeneScan and Genotyper software. Data acquired in these studies reinforced an existing body of knowledge and expertise regarding application and interpretation of STR typing in the forensic science community. Consistent STR genotypes were detected in various body tissues and fluids. Inter-laboratory comparisons produced concordant genotype results. Quantitative interpretational aids for DNA mixtures were characterized. Ability of the typing systems to type potentially compromised samples reliably was evaluated. Nonprobative case evidentiary DNA was successfully amplified, genotyped, and interpreted. Potential limitations or cautionary factors in the interpretation of minimal fluorescence intensity were demonstrated. Differential amplification between loci was observed when PCR was inhibited; preferential amplification typically was not. Single AmpFlSTR locus amplification did not offer consistent benefit over AmpFlSTR multiplexing, even in cases of DNA degradation or PCR inhibition. During rigorous evaluation, AmpFlSTR PCR Amplification Kits reproducibly yielded sensitive and locus-specific results, as required in routine forensic analyses. 相似文献

Grand Bank is a small fishing town on the southwest coast of Newfoundland, Canada. The oral history project, on which this paper is based, focussed on the “life stories” of women in three, four and sometimes five, different generations of families. My aim was twofold. First, I wanted to build a picture of the way to the economy, and the sexual division of labour has changed in the period 1890–present. Second, I wanted to see how, by focussing several accounts of the same family experience, I could break apart the ideological construction of the past. I could also use contrasting accounts of mothers and daughters to re-examine the role of “work” in the family and the construction of a sexual division of labour.This paper explores how women situate and construct both their past and present experience, and what the different accounts given by mothers and daughters and grandaughters tell us both about female family relationships and about the interaction of gender with economic, social and technological change. The paper also suggests why this particular oral history approach, using different generations of women in the same family, is especially relevant to feminist concerns. 相似文献

Several variant alleles of the HumD21S11 locus have only been reported in Australasian population samples. Fifteen such alleles were observed in Caucasian and Australian Aborigine sub-population databases compiled from residents of the state of Western Australia. Each variant was sequenced to authenticate the allelic designation and determine the structural conformation. Nine novel structural variants are described. The structure of the repeat region of these rare alleles combined with the STR designation brings aspects of the HumD21S11 nomenclature guidelines into question, in particular the designation of common incomplete repeats (or "0.2's"). The conformation of the sequences provides evidence in support of a genetic relationship between the Australian Aborigine and the Papuan people. 相似文献

Polygraph testing for deception in Australia: effective aid to crime investigation and adjudication?
McMahon M 《Journal of law and medicine》2003,11(1):24-47
Polygraph testing--or the monitoring and analysing of selected physiological measures of an individual who is being interviewed, for the purpose of detecting deception--is controversial in Australia. Considerable mythology surrounds this method of detecting deception. Embedded in popular perceptions of crime fighting and utilised in high-profile criminal cases in Western Australia, Victoria and Queensland, polygraph testing is also explicitly prohibited from being used in crime investigation in New South Wales. Unlike in the United States, polygraph testing has not hitherto routinely been used by government departments and authorities as a preemployment screening tool, but is increasingly being offered in the private sector in Australia. This article examines the current scope of polygraph testing in Australia, describes different approaches to testing, briefly reviews recent information relating to validity and evaluates State legislation prohibiting the use of polygraph testing for specified purposes in New South Wales. Consequent to the continuing controversy regarding the accuracy of polygraph testing in detecting deception (and, conversely, truth-telling), it is argued that the emerging use of polygraph testing is problematic and common law principles rendering the results of such testing inadmissible in court do not constitute sufficient safeguard against inappropriate and intrusive testing. Future research should identify specific polygraph testing techniques and consider the most socially beneficial way of regulating this emerging area of practice. 相似文献
