Using a Filemaker-based database (DNA Pro-FILES, Synchrone Infosystème Inc.), we have conducted a large-scale study on 1000 sexual assault (SA) cases where a standardized kit was submitted to our laboratory alone or with other types of exhibits. We looked at the likelihood of obtaining good quality DNA evidence, allegedly from the assailant, according to a number of parameters.The overall proportion of SA cases with DNA evidence is nearly 50%. A little more than 30% of SA kits provided DNA evidence while for 16% of cases DNA evidence could be obtained only from other exhibits.The likelihood of obtaining DNA evidence is approximately 50% in teenager and adult SA cases, but much lower for children 10 years old or younger (15%). In children cases, profiles were found mostly on clothing or skin swabs.The likelihood of obtaining DNA evidence from vaginal swabs remains good for up to 3 days after the assault (from 35% on the first day to 23% on the third day). A DNA profile was obtained from approximately 22% of anal/rectal swabs and 41% of skin swabs taken less than 1 day after the assault. Less than 10% of oral washes provided DNA evidence, all having been collected within 24 h of the assault.We found that in bodily samples, a negative result for acid phosphate (AP) is a poor predictor of the likelihood of obtaining good quality DNA evidence. Approximately 15% of vaginal swabs and 8% of anal swabs negative for AP nevertheless provided good quality DNA evidence. 相似文献

This study provides evidence that changing and increasing expectations of university, of students, and of academics of themselves have had an impact upon the perceptions of well-being in the law teachers who responded to this survey. A total of 185 UK law teachers completed a large survey which included demographic questions (age, academic qualifications, and experience), four questionnaires and a series of open-ended questions. Although most reported depression, anxiety and stress levels within the normal range, those who reported high stress levels were significantly more likely to report lower hope scores and higher obstruction of values scores as well as significantly less environmental mastery and self-acceptance. The results reported here indicate the importance of autonomy to law teachers. It is suggested that this is an issue that requires further investigation because of the potential for levels of psychological distress to increase. 相似文献

Diatoms are a group of unicellular algae that have been recorded and classified for over 200 years and have been used in a range of applications in forensic science. We have developed a quantitative diatom-based reconstruction technique to confirm drowning as a cause of death and localize the site of drowning in two recent, high-profile, case studies. In both case studies we collected diatom samples from the local and/or regional area to act as a control in the examination of diatom assemblages associated with lungs and clothing. In Case Study 1 the modern analog technique suggested that all lung and clothing samples have statistically significant similarities to control samples from shallow water habitats. In Case Study 2, the analog matching suggested that the majority of lung samples show a statistically significant relationship to samples from a pond, indicating that this was the drowning medium. 相似文献
