ABSTRACTThis article examines changing representations of women of colour within the realm of the visual arts and considers the aesthetic qualities, historical significance and cultural impacts of a diverse body of image-making spanning several centuries. The research focuses on selected works from the portfolios of the following four, early to midcareer artists of Caribbean heritage, whose nuanced depictions of black and brown womanhood in the twenty-first century have achieved international acclaim: American interdisciplinary artist Aisha Tandiwe Bell; American collagist Andrea Chung; French figurative painter Elizabeth Colomba; Danish photographer, video artist and performance installationist Jeannette Ehlers. The complex diasporic identities and imagery reflected in the oeuvres of these four contemporary artists are contrasted with fine art from earlier eras. The compositional, technical and social modalities of a number of notable works are assessed to determine why some have become celebrated images within the international canon and others have been deemed problematic. 相似文献

Prior research indicates that adolescent offenders transferred to adult court are more likely to recidivate than those retained
in the juvenile system. The studies supporting this conclusion, however, are limited in addressing the issue of heterogeneity
among transferred adolescents. This study estimates the effect of transfer on later crime using a sample of 654 serious juvenile
offenders, 29% of whom were transferred. We use propensity score matching to reduce potential selection bias, and we partition
the sample on legal characteristics to examine subgroup effects. We find an overall null effect of transfer on re-arrest,
but evidence of differential effects of transfer for adolescents with different offending histories. These results suggest
that evaluating the effects of transfer for all transferred adolescents together may lead to misguided policy conclusions. 相似文献

Mediation of medical malpractice lawsuits provides savings for the parties by shortening the litigation process. In theory, information that aids emotional healing and improves patient care can also surface through mediation. The study discussed in this article used structured interviews of participants and mediators in thirty-one mediated malpractice lawsuits involving eleven nonprofit hospitals. The study measured perceptions of the process and mediation's effects on settlement, expenses, apology, satisfaction, and information exchange. Defense lawyers were less likely than plaintiff attorneys to mediate. Both plaintiff and defense attorneys were satisfied with the process, as were plaintiffs, hospital representatives, and insurers. Changes in hospitals' practices or policies to improve patient safety were identified. This study demonstrates that major challenges stand in the way of achieving mediation's full benefits. Absence of physician participation minimizes the chances that mediated discussion of adverse events and medical errors can lead to improved quality of care. Change will require medical leaders, hospital administrators, and malpractice insurers to temper their suspicion of the tort system sufficiently to approach medical errors and adverse events as learning opportunities, and to retain lawyers who embrace mediation as an opportunity to solve problems, show compassion, and improve care. 相似文献

This study assesses the relative influence of various SES measures on the probability of intimate partner violence (IPV) among a national sample of White, Black, and Hispanic married and cohabiting couples. Participants were interviewed in conjunction with the 1995 National Alcohol Survey. Sociodemographic, psychosocial, and alcohol consumption data were obtained from both members of the couple. IPV was measured through the Conflict Tactics Scale, Form R. Bivariate tests were employed to investigate the association between SES and IPV. Deviance statistics, based on contrasting transformed likelihood measures obtained through multivariate logistic regression models, were computed to assess the relative influence of SES on the probability of IPV. Results indicate that annual household income had the greatest relative influence on the probability of partner violence. Future research is needed to explore the pathways by which SES contributes to the risk of partner violence. 相似文献

An extremely sensitive species-specific ARMS PCR test for the presence of tiger bone DNA 总被引:7,自引:0,他引:7
The survival of the tiger (Panthera tigris) is seriously threatened by poaching to provide raw materials for traditional Chinese medicines (TCMs). Most highly prized are the tiger's bones, which are used in combination with other animal and plant derivatives in pills and plasters for the treatment of rheumatism and other ailments. Hundreds of patent remedies have been produced which claim to contain tiger bone, but proof of its presence is needed if legislation prohibiting the trade in endangered species is to be enforced.A highly sensitive tiger-specific real-time PCR assay has been developed to address this problem. Using primers specific to the tiger mitochondrial cytochrome b gene, successful amplification has been reliably achieved from blood, hair and bone as well as from a range of TCMs spiked with 0.5% tiger bone. Although capable of detecting fewer than 10 substrate molecules, the seven varieties of TCM pills and plasters tested showed no detectable trace of tiger DNA before spiking. Furthermore, sequencing several "tiger bone" fragments seized from TCM shops has shown that they actually originated from cattle and pigs. The potential effects of traditional bone preparation methods, evidence that much lower concentrations are used than alleged on TCM packaging, and substitution of bones from other species all suggest a low likelihood of detecting tiger DNA in patent medicines. Despite this, the basic methods have been thoroughly proven and can be readily applied to derivatives from other Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) protected species, providing a rapid and highly sensitive forensic test for species of origin. Potential applications to the monitoring of wild populations are demonstrated by the successful identification of shed hairs and faecal samples. 相似文献
