To systematically review the worldwide evidence on the prevalence of domestic violence against women, to evaluate the quality of studies, and to account for variation in prevalence between studies, using consistent definitions and explicit, rigorous methods. Systematic review of prevalence studies on domestic violence against women. Literature searches of 6 databases were undertaken for the period 1995 to 2006. Medline, Embase, Cinahl, ASSIA, ISI, and International Bibliography of the Social Sciences were searched, supplemented by hand searching of the reference lists from studies retrieved and specialized interdisciplinary journals on violence. A total of 134 studies in English on the prevalence of domestic violence against women, including women aged 18 to 65 years, but excluding women with specific disabilities or diseases, containing primary, empirical research data, were included in the systematic review. Studies were scored on eight pre-determined criteria and stratified according to the total quality score. The majority of the sudies were conducted in North America (41%), followed by Europe (20%). 56% of studies were population-based, and 17% were carried out either in primary or community health care settings. There was considerable heterogeneity both between and within geographical locations, health care settings, and study quality The prevalence of lifetime domestic violence varies from 1.9% in Washington, US, to 70% in Hispanic Latinas in Southeast US. Only 12% scored a maximum of 8 on our quality criteria, with 27% studies scored 7, and 17% scored 6. The mean lifetime prevalence of all types of violence was found to be highest in studies conducted in psychiatric and obstetric/gynecology clinics. Results of this review emphasize that violence against women has reached epidemic proportions in many societies. Accurate measurement of the prevalence of domestic violence remains problematic and further culturally sensitive research is required to develop more effective preventive policies and programs.  相似文献

Renal infarction is an uncommon finding at autopsy most often related to occlusive thromboembolism or to trauma. A 42-year-old woman is reported who presented with persistent right flank pain after an alleged assault with injury to the area 3 weeks previously. Renal infarction necessitated a right nephrectomy that was followed by multiorgan failure and death. Given the possible link between the assault and the renal pathology, a homicide investigation was initiated. Although renal infarction had been confirmed by hospital pathologists, microscopy with special staining of both kidneys and the heart after autopsy revealed multifocal areas of angioinvasion by fungi having morphologic characteristics of mucormycosis. The only other finding of significance was alcohol-related micronodular cirrhosis of the liver. Renal infarction had therefore been caused by an angioinvasive fungal infection predisposed to by immunocompromise associated with alcoholism and not by trauma-induced arterial dissection. This case demonstrates that careful histological assessment of tissues from medicolegal autopsies may occasionally identify unexpected and rare disorders that have been confused with the sequelae of inflicted injury.  相似文献

Although drowning in rainwater tanks is a generally rare phenomenon, this method for suicide has been observed in parts of Croatia. Review of autopsy records at the University of Rijeka, Croatia, was undertaken from 1987 to 2016 to examine this phenomenon. Of 469 drowning deaths, there were 35 suicides in rainwater tanks (7.5%). Overall drowning deaths showed no temporal trends. In contrast, suicidal drownings in rain water tanks showed a marked decline over the years, with 15 cases in 1987–1991, seven in 1992–1996, six in 1997–2001, six in 2002–2006, one in 2007–2011, and none in 2012–2016. Thus, suicidal drowning cases as a percentage of overall drownings dropped from 18% to zero (p<0.001). This study reports a very unusual method of suicide that may have occurred because of the ready availability of large water reservoirs in homes. The recent fall in numbers may relate to less reliance on domestic reservoirs of water.  相似文献

From 1982 to 1994, the balance of trade deficit for U.S. telecommunications services increased by tenfold. The Central and South American countries contributed greatly to this increase. Our analysis identifies partner reciprocity as a core issue of the international long-distance industry. We apply an economic anthropology perspective to suggest that the antecedent conditions of cultural distance, economic nearness and relative country-risk will affect a foreign partner's reciprocity and examine U.S.- Latin American contracts over 11 years to test our respective hypotheses.  相似文献

What if we viewed the history of human spaceflight somewhat less through the lens of Cold War politics, which admittedly was central to the race to the Moon, but more as an expression of what might be called a religion of spaceflight? There seems to be a deeply religious quality to advocacy for the investment in and support for human space exploration, lending to the endeavor of a “higher purpose” that helps to explain both the generous nature of the actual investment and the ultimate unwillingness of Americans to eviscerate space budgets despite less than full support for space exploration. This article examines religious conceptions as a means of analyzing what might be termed a “space gospel.” I lay out here the proposition that human spaceflight may be viewed as a religion with similar attributes to those present in mainstream religious denominations. This approach to exploring the history of human spaceflight offers a different and useful frame of understanding that broadens basic conceptions about this aspect of the human past.  相似文献

To date, only four paying space tourists have flown, and the prospect for broad, sustainable space tourism remains a dream. This article notes that there are two types of tourists conflated by the advocates of space tourism. The first are a tiny group of adventurers with significant wealth and other resources who seek thrills and bragging rights. They have enjoyed success in using government-owned resources for their extreme tourism experience by flying on Soyuz capsules operated by Russia, and the International Space Station owned and operated by a consortium of nations as a major research station. The second group seeks more modest excursions with a minimum of risk and a smaller price tag. Only the first group has much prospect for tourism in space in the foreseeable future, but the second group is the more important, and expanding its space tourism opportunities represents the primary means of achieving the goal of opening space to the public. This article also differentiates between private sector suborbital space tourism, which may achieve reality within the next five to seven years, and the prospects for orbital space tourism, which are at least an order of magnitude more difficult and will probably require at least another generation of technological work to achieve.  相似文献
