Detection of blood on dark materials is difficult for crime scene examiners so presumptive tests are used to assist. This study compared the ability of luminol, leuko crystal violet, tetramethylbenzidine, and Combur Test®E to detect whole, diluted blood (1:100) and a key‐shaped blood transfer stain (1:10), on dark cotton sheeting, tea towel, socks, synthetic carpet, and car mats. Powdered bleach was used to evaluate specificity of the blood detection tests. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and overall misclassification rate (OMR) assessed the quality of the blood tests. Luminol was the preferred test for diluted blood having the highest sensitivity (79%–96%), NPV (66%–93%), and the lowest OMR (3%–15%). Luminol was also found to be most efficient with a testing time on 25 items of 2 h 50 min compared with up to 8 h. Overall, luminol was the most effective method, also providing information on bloodstain patterns.  相似文献

This summary relates to the consultation held at St George's House, in Windsor, England, on February 2018. The attendees came from across Europe and from the United States, and they discussed a range of initiatives designed to address the challenges in modern family justice and the changes in the social, political, and economic environments that are impacting family life across the globe. Although the challenges are very similar, the approach to resolving them varies from jurisdiction to jurisdiction. The attendees concluded that there is much we can learn from each other, and that greater cooperation between family justice professionals across geographic boundaries would be highly beneficial.  相似文献

Early sexual behaviors during adolescence have the potential to lead to unhealthy outcomes. This study explored the association between specific dimensions of maternal relationship quality and adolescent sexual debut by age 15. We hypothesized that adolescents who have poor maternal relationships are at greater risk of early sexual debut than those who have a more supportive relationship. These hypotheses were examined using both adolescents’ perception of their maternal relationship quality and observed relationship quality. A sample of 268 adolescents (142 girls; 90% European American) were followed longitudinally from age 13 to age 15. The results indicate that adolescents with sexual debut by age 15 report significantly worse relationships with their mothers compared with other adolescents. Furthermore, behavioral observations of lower maternal support and higher observed displays of externalizing affect towards the mother also were related to early sexual debut. The significance of maternal relationship quality remained after controlling for family structure, race, and socioeconomic status. These findings suggest that mothers have a significant role in the timing of their adolescents’ sexual debut.  相似文献

This paper describes the multidisciplinary project Founders and Survivors: Australian Life Courses in Historical Context. Individual life courses, families and generations through the nineteenth and twentieth centuries are being reconstituted from a wide range of data including convict records; birth, death and marriage registrations; and World War I service records. The project will result in a longitudinal study of Australian settlement, the long-run effects of forced labour and emigration on health and survival, family formation, intergenerational morbidity and mortality, and social and geographic mobility.  相似文献

This study examined individual and work-level factors that impact job stress and satisfaction for correctional officers. Existing research has explored officer job stress and satisfaction, but very few studies have focused specifically on fear of contracting an infectious disease while at work (HIV/AIDS, hepatitis, and tuberculosis), and the impact fear of and exposure to infectious disease have on correctional officer job stress and satisfaction. Random sample data were collected from 2,999 male and female officers from across the state of Texas to assess job stress, satisfaction, personal safety, and exposure to infectious disease. Ordinary Least Squares analyses indicated that fear of disease was positively correlated with job stress, and inversely correlated with job satisfaction. Exposure to disease however, failed to yield any significant effects on job stress or satisfaction. Officers who felt that their supervisors were supportive of them on the job reported less stress and higher satisfaction levels, while perceived dangerousness of the job was positively correlated with job stress. These findings highlight the importance of supervisory support as well as continuous, in-depth education and training on infectious diseases for officers.  相似文献

We compare results of several large‐scale survey studies of whistle‐blowing by public sector employees, from samples in Australia, Norway, and the United States. Specifically, we review incidence rates of wrongdoing, whistle‐blowing and retaliation, as perceived by thousands of respondents employed by many government agencies in these countries. Despite differences in measurement in the studies and variation in results, findings suggest that wrongdoing was quite frequently observed and was reported in many cases. Retaliation resulted for far fewer than half of the whistle‐blowers, in all three nations. We also compare findings from the various studies concerning variables that predicted retaliation against whistle‐blowers in the different samples. Differences in results across the three countries add to existing evidence that country and workplace cultures can affect the whistle‐blowing process.  相似文献

This introduction reviews the contributions this collection of articles makes to understanding migration, social reproduction and social protection. Migration necessarily involves reconfigurations of family relations and these entail changes in the patterning of social (in)security. Our expansive interpretation of the concepts of social reproduction and social protection situate the reorganisation of gendered family lives as integral to the migration–development nexus. Life-course thinking informs analysis of how migrants ‘do family’ and what this means for gender, identity and (in)security. The collection explores how ‘care deficits’ are managed, both discursively through the negotiation of gendered ideologies about gender identity and the family, and through the everyday practice of social reproduction. The resulting reorganisation of social security involves taking on new risks and vulnerabilities for migrants and their families. For both internal and international migrants the challenges involved in securing social reproduction are powerfully shaped by welfare and migratory regimes and raise important questions about the relationship between social protection and broader social policy and citizenship issues.  相似文献
