The occurrence of secondary DNA transfer has been previously established. However, the transfer of DNA through an intermediary has not been revisited with more sensitive current technologies implemented to increase the likelihood of obtaining results from low‐template/low‐quality samples. This study evaluated whether this increased sensitivity could lead to the detection of interpretable secondary DNA transfer profiles. After two minutes of hand to hand contact, participants immediately handled assigned knives. Swabbings of the knives with detectable amounts of DNA were amplified with the Identifiler® Plus Amplification Kit and injected on a 3130xl. DNA typing results indicated that secondary DNA transfer was detected in 85% of the samples. In five samples, the secondary contributor was either the only contributor or the major contributor identified despite never coming into direct contact with the knife. This study demonstrates the risk of assuming that DNA recovered from an object resulted from direct contact. 相似文献

Intimate partner violence (IPV) is a prevalent problem associated with multiple negative outcomes for survivors’ well-being. Coping has emerged as an important construct in understanding the association between IPV and survivors’ well-being. Research is needed to better understand the contextual complexity of IPV as a stressor, determine if IPV is a unique stressor, and document survivors’ coping experiences. This article reports findings of a qualitative study with 25 female survivors and 6 service providers. Analysis of interview data shows 3 key themes: (a) coping strategies used by survivors; (b) challenges and barriers to coping with IPV; and (c) IPV as a unique stressor. Despite multiple challenges and barriers to coping with IPV, survivors use multiple, varied strategies to cope with their experiences of abuse. However, given the context and nature of IPV, violent victimization is a distinct stressor with unique barriers that often require IPV-specific coping strategies. 相似文献

This article reports findings from a qualitative follow-up investigation of a mandated parenting and safety program for system-involved female IPV survivors. Participants were contacted 12 months or more after program completion and invited to participate in individual interviews. The interviews focused on the longer-term life changes survivors attributed to the program. Data were collected from 38 survivors. Qualitative analysis determined 4 key themes: relationship changes (e.g., most women were no longer with abusive partners), parenting changes (e.g., improved communication and discipline strategies), personal life changes (e.g., improved help-seeking and self-esteem), and new or ongoing challenges (e.g., financial stress). Overall, findings suggest that tailored, mandated programming — when positive and empowering — may lead to some longer-term beneficial outcomes. 相似文献

Spectator violence has long been associated with professional football in Europe. This article examines the issue of spectator violence from a North American perspective. We begin by noting that there is little systematic research into the scope of spectator disorder in North America. Perhaps for this reason there is little consensus about the true scale of the problem on this side of the Atlantic. It does seem clear at least that there is less spectator violence associated with professional sports in North America. After reviewing a number of explanations for this finding, we conclude that it has less to do with criminal justice policies or practices, than the social context surrounding the 'spectatorship' of sports in North America. Perhaps the most important explanation for the variance in crowd behaviour concerns the demographic profiles of sports spectators in European football and North American sports. 相似文献

Abstract: The quality and efficiency of a standard organic DNA isolation method and a silica‐based method using the QIAGEN Blood Maxi Kit were compared to obtain human DNA and short tandem repeats (STRs) profiles from 39 exhumed bone samples for paternity testing. DNA samples were quantified by real‐time PCR, and STR profiles were obtained using the AmpFlSTR® Identifiler® PCR amplification kit. Overall, the silica‐based method recovered less DNA ranging from 0 to 147.7 ng/g (average 7.57 ng/g, median = 1.3 ng/g) than did the organic method ranging from 0 to 605 ng/g (average 44.27 ng/g, median = 5.8 ng/g). Complete profiles (16/16 loci tested) were obtained from 37/39 samples (95%) using the organic method and from 9/39 samples (23%) with the silica‐based method. Compared with a standard organic DNA isolation method, our results indicate that the published silica‐based method does not improve neither the quality nor the quantity of DNA for STR profiling. 相似文献

Use of an Automated Nested Multiplex Respiratory Pathogen PCR Panel Postmortem in the Pediatric Forensic Setting 下载免费PDF全文
Tiffany Baker M.D. Ph.D. Cynthia Schandl M.D. Ph.D. Susan Erin Presnell M.D. James Madory D.O. Frederick S. Nolte Ph.D. Nicholas Batalis M.D. 《Journal of forensic sciences》2017,62(5):1223-1228
Respiratory pathogens have been detected in forensic investigations using multiple techniques; however, no study has examined the use of automated, nested, multiplex polymerase chain reaction (ANM‐PCR), commonly used in living patients, in the forensic setting. This retrospective study assessed the utility of ANM‐PCR in detecting respiratory pathogens in the pediatric forensic setting. Respiratory samples from 35 cases were tested for up to 20 respiratory pathogens. 51.4% of these cases yielded a positive ANM‐PCR result, 20% of which were considered the cause of or contributory to death. The most commonly detected pathogens were rhinovirus/enterovirus and respiratory syncytial virus, and these were the only pathogens determined to play a significant role in cause of death. The sampled sites and postmortem intervals tested did not affect the likelihood of a positive or negative test. ANM‐PCR panels are effective, affordable, and rapid ancillary tools in evaluating cause of death in the forensic pediatric population. 相似文献
