Many abused women use professional and community services and begin to talk to professionals about the abuse they have endured. This article presents and discusses results of a study of 270 abused women who used the services of professionals and service agencies. The article presents information on the frequency of contact and the perceived helpfulness of different professions. Also presented are the types of responses which were considered to be useful and ineffective. This study revealed that the most frequently contacted professions were not necessarily perceived to be the most helpful. Further, certain responses of the service providers were more frequently reported to have value. 相似文献

The Green River Murder Investigation in King County, Washington, is currently the longest active serial murder investigation in U.S. history. During its course, over 26 separate scenes with from one to five victims each have been processed. The experience of the authors is presented in order to acquaint other agencies with techniques of outdoor scene processing that have evolved during recovery of remains from Green River and other skeletal cases. 相似文献

The population-adjusted rate of teenage suicide in King County, Washington, was reviewed for the 26 years from 1959 to 1984. For the entire period, the rate did not change significantly. An abrupt change did occur during the middle of this period, but, for reasons discussed in the text, this may well represent a change in procedures and philosophy of death certification rather than a real change in rate. Reasons for the apparent discrepancy with national statistics are discussed. 相似文献

The effectiveness of harsher sanctions for domestic violence offenders is an important topic given legislative trends in “getting tough” with these offenders. This article takes a rare look at felony domestic violence, specifically felony assaults on female intimates, with an analysis of whether conviction, jail, and imprisonment are related to the odds of subsequent charges among 353 male defendants from twenty-four Ohio trial courts of general jurisdiction. Each defendant was followed up for two years after his original case was closed and his sentence (if any) was served. Conviction and jail sentences were both related to significantly lower likelihoods of recharging for intimate assault, but prison sentences were not related to these odds. These findings are discussed in relation to the potential importance of reducing short-term opportunities for violence in order to prevent future harm. 相似文献

In the statistical interpretation of forensic glass evidence it is standard practice to make the assumption of homogeneity of the refractive index (RI) of the source glass, or of localized homogeneity. However, the work of Locke and Hayes showed that, for toughened windscreen glass, this assumption might not be true. This work is well cited, but there appears to have been little follow-on published research. Furthermore, the toughening process is something known to affect the refractive index, and is a process that float glass does not undergo. Float glass is a major component of casework in New Zealand and for that reason it would be interesting to know whether the findings of Locke and Hayes apply when dealing with float glass. In this paper we describe an experiment similar to that of Locke and Hayes, systematically examining the variation of RI in a pane of float window glass. It was found that, although there were no systematic differences in refractive index, there were observable differences across the pane. 相似文献

Report of an unusual finding of bones on the shore of the Baltic Sea. Although the morphological findings appeared similar to a human foot skeleton, a quick identification as sea dog bone was possible. 相似文献
