A skeletonized body, wearing a black leather bondage mask, was found in a Revolutionary War smokehouse cave with two bullet holes in the back of the head. The body was skeletonized up to the maxillary area but the head region under the mask was well preserved and permitted a positive visual identification. There was evidence that the body had been eaten by small animals and subsequently burned. Investigations into this brutal murder revealed a tale of a bizarre sadomasochistic ritual that attained national prominence.  相似文献

Relatively little is known about rural women's intimate violence experiences in comparison to urban women's experiences, partly because of the difficulty in accessing rural women. This pilot study used a protective order sample of 23 women (15 urban and 8 rural), which provides an access point that is relatively similar for comparisons across rural and urban areas. The number of participants is low and, therefore, results are preliminary. However, several significant findings emerged. Rural women reported significantly less social support, less education, less income, more physical abuse in the preceding year, more childhood physical and sexual abuse, and worse overall health and mental health, as well as encountering abuse earlier in the relationship. Both groups reported higher rates of illegal drug and cigarette use than those among the general population. The findings highlight some overall important themes in examining rural and urban intimate violence victims by suggesting that rural and urban intimate violence victims have different victimization experiences and service needs. Implications for further research and intervention are discussed.  相似文献

Recently, attention was again drawn to the use of microspectrophotometry to distinguish between fibres dyed with indigo and seven derivative dyes. Under normal circumstances, fibres dyed with indigo (Vat Blue 1 or CI Number 73000) are not included in fibre-transfer examinations as, being ubiquitous, they do not usually have any evidential value. Indigo substitutes are used for fashion dyeing. If their use is widespread, the assumption that all denim material is dyed with Vat Blue 1 may need revising. A positive finding might make it necessary to reconsider the use of certain denim fabrics as capable of providing target fibres. Fibres from 160 samples of denim articles in current use were examined by microspectrophotometry to determine whether either indigo derivative dyes, or other dyes, had been used instead of the traditional indigo.  相似文献

过去30年来,台湾民众的民族认同和台湾政府的国家认同危机的发展、台独势力的扩张以及民主的进程,虽促进了台湾社会的发展,同时也加剧了海峡两岸的矛盾和对立,并可能把台湾推向战争的灾难。台湾民众和台湾政府对面临的现实和可能要作出选择,最终解决台湾的认同危机。  相似文献

The United States prison population is becoming more diverse and comprised of increasingly more violent inmates. Although race has been cited as a risk factor for inmate violence, most prior research had narrowly investigated White/Black differences in inmate misconduct. Using a sample of 1,005 inmates from the southwestern U.S., the current study explored racial, ethnic, and citizenship correlates among male and female prisoners. Negative binomial regression models indicated that net of controls, Hispanics and Native Americans were the most violent male prisoners, while African Americans and Native Americans were the most violent female inmates. The current study was admittedly modest in scope; however, the findings were couched within a broader, imperative sociological framework that lamented the increasing interplay between communities and prison and the role of prison as a social institution.  相似文献

Allele frequencies for six tetrameric short tandem repeat (STR) loci CSF1PO, TPOX, THO1, D3S1358, VWA, and FGA were determined in a Black African sample population from Zimbabwe. All loci are highly polymorphic and meet Hardy-Weinberg expectations. An inter-class correlation test analysis detected only one departure from independence out of 15 pair-wise comparisons of the six loci (i.e., CSF1PO/VWA loci, P=0.026). The allele frequency data at four of the six STR loci in the Black African sample population are similar to African American data.  相似文献
