Sex determination is a key analysis that forensic anthropologists perform in order to construct a biological profile of human remains. The techniques used in forensic investigations must meet the Mohan or Daubert criteria, for admissibility in a court of law. In this study, the precision and accuracy of 21 morphological characteristics of the skull were tested on a modern sample of 50 adult crania of European White ancestry. The following craniofacial features are identified as high-quality traits, defined by intraobserver error or=80%: mastoid size, supraorbital ridge size, general size and architecture, rugosity of the zygomatic extension, size and shape of the nasal aperture, and gonial angle. Ninety-six percent accuracy and 92% precision were achieved using 20 traits in combination. Fisher's exact probability tests revealed no significant differences (p=0.05) in the levels of precision or accuracy between age categories. Sex-related bias in accuracy was found for the following cranial features: ramus symphysis (p=0.009), zygomatic extension (p=0.0016), and occipital markings (p=0.0013). These traits demonstrated a greater tendency to be scored male than female. 相似文献

Helping women victimized by intimate partner violence (IPV) is a challenge, particularly when the women belong to diverse ethnic groups. The objective of our study was to collect information on perceptions of coping with IPV from the perspective of a specific immigrant group of women. Sixty-three women from the Tamil community in Toronto representing different generations and experiences of IPV were interviewed in focus group settings about their views of coping with IPV. Study findings suggested that their views were deeply embedded in their sociocultural context and influenced by the gender-role expectations from the community. The women showed a marked preference for “passive” modes of coping rather than “active.” Study findings have implications for the development of alternative approaches to helping ethnically diverse women deal with IPV. 相似文献

Matching dental antemortem (AM) and postmortem (PM) data for human identification is especially challenging when the workforce is limited. Dental hygienists have served mass fatality incidents (MFIs) due to dental-related expertise. However, forensics within dental hygiene education and research on transferable skills is limited. This qualitative balance design study assessed senior dental hygiene students' match accuracy of simulated cases varying in dental identifiers based on AM full mouth series (FMS) radiographs and oral photographs to PM WinID3® odontograms to demonstrate possible disaster victim identification (DVI) transferable skills gained during formal education. A convenience sample of senior dental hygiene students (n = 31) was presented information on WinID3® interpretation, then presented with 5 mismatched cases and asked to visually interpret each to make 10 total matches; five based on AM FMS with simulated PM WinID3® odontograms and five based on AM photographs with PM WinID3® odontograms. Match accuracy scores ranged from 41.9% to 58.1% for cases with 1–10 identifiers, and 77.4% to 93.5% for cases with 11–40 identifiers. Accuracy when matching AM radiographs to PM odontograms versus AM photographs to PM odontograms was compared and revealed no statistical differences in match accuracy depending on image type (p = 0.388 to 1.000). Results of this pilot study suggests transferable match accuracy skills resulted from the participants' dental hygiene formal education. These baseline skills with additional specialized training support the rationale for dental hygienists serving on DVI teams. More research is needed in education and practice when preparing dental hygienists for forensic-based service. 相似文献

The importance of social media for election campaigning has received a lot of attention recently. Using data from the 2011 New Zealand general election and the size of candidates’ social media networks on Facebook and Twitter, we investigate whether social media is associated with election votes and probability of election success. Overall, our results suggest that there is a statistically significant relationship between the size of online social networks and election voting and election results. However, the size of the effect is small and it appears that social media presence is therefore only predictive in closely contested elections. 相似文献

Norm Diffusion and Reputation: The Rise of the Extractive Industries Transparency Initiative 下载免费PDF全文
Transparency in the extractives sector is widely seen as an important tool for improving accountability and deterring corruption. Yet for those very reasons, it is a puzzle that so many governments in corruption‐prone countries have voluntarily signed up to greater scrutiny in this area by joining the Extractive Industries Transparency Initiative (EITI). We argue that EITI serves as a reputational intermediary, whereby reformers can signal good intentions and international actors can reward achievement. International and domestic actors thus utilize EITI to diffuse the norm of resource transparency and to advance reformist aims in a highly problematic policy area. 相似文献
