The Y-PLEX 6 and Y-PLEX 5 systems enable analysis for 11 Y-STR loci. We present here the utility of these systems in forensic casework. A total of 188 samples, including 127 evidence samples, were analyzed using either or both of the systems. The evidence sample types included fingernail scrapings, sperm or seminal fluid, epithelial cells, blood and other tissues. The Y-STR typing systems provided useful probative results in difficult cases. A reference database for Caucasian (n = 517), African American (n = 535), and Hispanic (n = 245) population groups within the United States was generated for estimating the haplotype frequency in forensic casework. Among the individuals profiled, 311 Caucasians, 412 African Americans, and 194 Hispanics provided unique profiles in their respective population datasets. This is the first report describing the haplotype database for the set of 11 Y-STR loci recommended by the Scientific Working Group on DNA Analysis Methods (SWGDAM). Linkage analysis reveals that the frequencies from forensically important autosomal loci can be multiplied with the Y-STR haplotype frequency. The results from Y-PLEX systems have been accepted in courts in the United States. 相似文献

Negotiation teachers encourage their students to be inventive,improve agreements, and push outward on the "pareto" frontier.Likewise, teachers can improve their practice by seeking value, sometimesin other disciplines. In general, negotiation is taught through acombination of lectures with simulation exercises and debriefings. Feministpedagogy enhances this normative model of teaching negotiation. Thisarticle links the traditional method of teaching negotiation with four keyprinciples of feminist pedagogy. 相似文献

Pregnant and parenting adolescents often cope with a lack of resources as they struggle to negotiate the tasks of motherhood and adolescence. Previous research has determined that young mothers have an increased rate of depression when compared to older mothers. In this study, self-perceived resource adequacy, education, income, age, and environment (urban vs. non-urban) were investigated as predictors of depression at approximately 14 and 36 months after birth in adolescent mothers (N=523). Self-perceived resources accounted for significant variance in depression at 14 and 36 months while controlling for education and income. However, education and income were not significant predictors while controlling for self-perceived resources. Age and environment did not predict depression. Researchers would be wise to focus on a young woman’s view of her situation, as it appears that self-perceived resources play an important role in predicting depression.Post-Doctoral Research Associate at Juniper Gardens Children’s Project, University of Kansas.

The role of the intellectual is traditionally gendered masculine, and women are excluded from consideration. Contemporary discussions of the 'death of the intellectual' noticeably make no reference to feminist intellectuals. On the other hand, women in academia have been reluctant to adopt the role of public intellectual as conventionally defined. There is an anxiety about the contemporary place of the intellectual, and about the necessity for the distinction made by some feminists between theory and practice, the intellectual and the activist, and where this might lead. In exploring the role of feminist intellectuals over the last two centuries, three paradigms of the feminist intellectual are proposed for consideration: Cassandra (the prophetess cursed with disbelief), for example Florence Nightingale; the feminist Messiah (the exceptional female saviour who would sacrifice herself to change women's lives), for whom the exemplar is Margaret Fuller; and the Dark Lady (the token woman in a community of men), such as de Beauvoir, Mary McCarthy and Susan Sontag. Indeed, Camille Paglia's rivalry with Sontag lends itself to being interpreted as evidence of her current desire to occupy this 'dark lady' role. In conclusion, after discussing contemporary, late twentieth-century feminism (Natasha Walter, Elizabeth Wurtzel, gurrl power, 'women behaving badly'), the role of Margaret Thatcher in changing perceptions of women's capacity for political power is proposed for celebration. Finally, there is Cixous's image of the feminist intellectual as the laughing Medusa, who turns men to stone, but turns laughter on herself. 相似文献
