AbstractI first read about you and your book, The Woman Warrior, in the book review sections of several magazines and Sunday newspapers. I read Susan Brownmiller's interview with you in “Mademoiselle” magazine, Jane Kramer's review of your book in the New York Times, and Nan Robertson's interview with you, also in the Times. In addition, several white feminist friends were telling me I should read your book “because it is a powerful, feminist story by a Chinese American woman.” So I read your book. 相似文献

The investigation of samples with low amounts of template DNA remains at the forefront of forensic DNA research and technology as it becomes increasingly important to gain DNA profile information from exceedingly trace levels of DNA. Previous studies have demonstrated that it is possible to obtain short tandem repeat (STR) profiles from <100 pg of template DNA by increasing the number of amplification cycles from 28 to 34, a modification often referred to as “low copy number” or LCN analysis. In this study, we have optimised post-PCR purification techniques applied after only 28 cycles of PCR, as well as using modified capillary electrophoresis injection conditions and have investigated the progressive application of these enhanced approaches. This paper reviews the characteristics of the profiles obtained by these methods compared with those obtained on the same samples after 34-cycle PCR. We observed comparable sensitivity to 34-cycle PCR in terms of the number of profiles with evidence of DNA and the number of allelic peaks per profile and we noted improved peak height and area magnitude with some sample types. Certain parameters reported to be adversely affected in 34-cycle LCN investigations, such as non-donor allele peaks and increased stutter peak ratio, were reduced by this approach. There are a number of advantages for trace samples in progressing from the standard 28-cycle process to the post-PCR processing method as compared to 34-cycle PCR method, including reduced sample consumption, reduced number of PCR amplifications required, and a staged approach to sample processing and profile interpretation. 相似文献

Valuing indigeneity is a recent phenomenon despite a long tradition in Aotearoa New Zealand of mechanisms that recognize Māori rights and interests. Political pressure to acknowledge indigeneity has been a prerequisite to greater recognition of Māori rights and interests in environmental policy. Māori involvement is now a feature of the state resource management system; however, more substantive forms of power-sharing is sought to secure tribal authority, to reaffirm Māori culture, and to ensure that land continues to shape the identity of Māori people. 相似文献

Abstract: Analyses of saw marks in bone may yield important information about the class characteristics of saws used in postmortem dismemberments, yet little research has been directed at identifying saws’ individualizing characteristics. This study adds to existing saw mark analysis methodologies by examining wear‐related features of kerf walls using light‐ and environmental scanning electron microscopy. A crosscut saw and hacksaw were used to create sequences of 30 cuts in bone; these sequences reveal patterns of progressive loss of fine details of kerf wall morphology with increasing saw blade wear, because of the rounding of sharp points and edges. Nevertheless, diagnostic kerf wall features used to establish class characteristics persist despite these wear‐related changes. Unsuccessful attempts at statistical analysis of wear‐related changes, based on striae width and density, suggest these patterns are not readily quantifiable. Additionally, despite the scanning electron microscope’s superior imaging capabilities, it provided few practical, methodological gains over traditional light microscopy. 相似文献
