Polydimethylsiloxane (PDMS) is commonly used to lubricate condoms. The detection of PDMS on swabs from complainants can be used to support an allegation of sexual assault. Previous research has focused on establishing analytical techniques for detecting PDMS. This research examined the persistence of PDMS on the penis, in the vagina, in the mouth, and on skin. The longest PDMS detection times were 20 h on the penis, 35 h in the vagina, and 52 h on skin. PDMS was detected up to 4 h in the mouth if the participant did not eat or drink and up to 9 h if the participant slept. PDMS was not detected in the mouth after eating or drinking. The presence of biological fluids had no detrimental effect on the analysis. Aqueous extraction of swabs for DNA did not remove any significant amount of PDMS; hence, swab remains could be subsequently analyzed for PDMS. 相似文献

This study examined the self-regulatory process of moral disengagement in adolescent social bullying. Moral disengagement was assessed at the individual level, as well as within reciprocated very best friendships. At the dyadic level, this study investigated the role of friendship quality in moderating the influence of a very best friend’s moral disengagement on adolescents’ social bullying. The sample consisted of 710 mainly White students (306 males, 12–17 years). Results showed adolescents’ proneness to moral disengagement was associated with increased social bullying. Further, a very best friend’s moral disengagement was associated with higher social bullying for those who perceived positive qualities in their friendship. The findings highlight the importance of close friends in fostering adolescents’ social bullying. 相似文献

The provision of forensic science services in volume crime investigations works most successfully as a partnership between police agencies and external forensic laboratories as opposed to a client/provider model where unlimited demand ignores finite resources. The principles of Lean Six Sigma have been applied in various laboratories to improve workflow through identification of wasteful work practices. These strategies are aimed at process optimisation through the application of triaging, a concept that has rarely been studied yet referenced strongly in the literature. The South Australia End to End 90-Day Trial: facilitating quicker justice through timely evidence processing, is a collaborative approach between South Australia Police and Forensic Science South Australia. This trial applied evidence-based policing principles, a law enforcement philosophy that uses research undertaken with scientific processes to inform law-enforcement decision-making. The results demonstrate how a review of processes and the removal of non-value adding activities can improve service delivery while not exhausting those ‘finite resources’. 相似文献

To test the hypothesis that adolescent females who are high in ego identity have high interests in religious and political values, the relationship between the ego identity status of 80 senior high school females and their response to the Allport-Vernon-Lindzey Study of Values was examined. Participants classified as being identity achievements, moratoriums, and foreclosures had higher religious value scores than did diffusions; however, the expected differences on political value scores were not found. Two-thirds of the identity achievers came from homes disrupted by divorce or death of one parent, while less than 20% of the members of the other three statuses came from broken homes.This report is based on the first author's M.A. thesis, which was submitted to the Graduate School, Texas Woman's University, 1978.Received her M.A. from Texas Woman's University. Major interests are ego identity formation and female adolescent development.Received Ph.D. from Louisiana State University, Baton Rouge. Major interests are developmental effects of stress and neurophysiology. 相似文献
