Tests have determined that boots or shoes of individuals at a fire scene do not transport sufficient contaminants ("tracking") through the fire scene to produce a positive laboratory result for the presence of gasoline in a fire scene that was not present at the time of the fire. Questions about the validity of forensic laboratory results have been raised on the basis that low-level gasoline residues detected in the laboratory samples could have been the result of transporting the residue by footwear contaminated from the fire scene ("tracking"). The data collected in this study establish that "tracking" does not lead to false-positive laboratory results. Canines trained and experienced in the detection of trace ignitable liquid residues were also utilized in this study. The canine results confirmed that properly trained canines show a higher sensitivity than do standard ASTM laboratory techniques for fire debris analysis. In a few cases, canines responded to contamination, but laboratory testing (which is the definitive indicator) did not produce positive results.  相似文献

We report on a sample of 135 deliberate self-harm (DSH) patients who were assessed by a general hospital DSH service, and on those who were offered aftercare by, or telephone open access to, the service. Patients' satisfaction with assessment and treatment, and their outcome were investigated at follow-up 12-20 months later. Four-fifths of patients reported the assessment following DSH to have been helpful and the assessor sympathetic. Thirty-three (24%) of the 135 patients assessed were offered treatment by the DSH service but 13 declined or failed to attend. Of the 20 who engaged in treatment, 17 (94%) were satisfied with their care. Open access to the DSH service by telephone was offered to 53 (39%) patients, nine (22%) of whom reported at follow-up that they had used this facility. A specialist DSH service can effectively assess and treat patients following DSH. It is important that the service is accessible and acceptable to patients.  相似文献

States closely regulate the policies of their local units of government through the imposition of direct order mandates. The general literature on state as well as federal mandate activities suggests that such regulations seriously constrain local autonomy and add to local financial burdens. A case study of the application of California's planning mandates in a sample of small nonmetropolitan cities suggests that major programmatic mandates are not always restrictive; mandates can be beneficial by empowering local officials.  相似文献

The high social cost of domestic violence has caught the attention of lawmakers and criminal justice agency administrators across the country. As public awareness and concern over the incidence of domestic violence has risen, domestic violence legislation has focused on, among other things, the law enforcement response to domestic violence. The purpose of this study is to examine Florida law enforcement agency response to domestic violence by analyzing agency standard operating procedures (SOPs) across measures identified in the Florida Model Policy for Domestic Violence. Utilizing content analysis, the authors identify agency policy mandates including the number of officers responding to the scene, the use of specialized units, availability of victim advocates, and procedures for investigation.  相似文献
