We report a case where an alleged father (AF) attempted to substitute someone else's saliva sample for his reference sample in a paternity analysis. Buccal cells were collected from the AF and the child, and DNA analysis was performed using an autosomal STR loci (Identifiler). The profile from the AF showed extra peaks in some loci, as well as a much higher "X" allele peak relative to the "Y" allele peak at the amelogenin locus. After conducting reanalysis by another technician with another set of positive and negative controls, it was concluded that the only source of the mixed profile was by intentional introduction by the AF, at the time of sampling, of some foreign human biological material, most likely saliva from a woman. Owing to the inconclusive results, when the AF was called back to the lab and the peculiar results were explained to him, he admitted that he had introduced into his mouth saliva from another person in an attempt to be excluded as the father of the child. Although tampering with DNA reference samples is not common, some individuals may attempt to contaminate or otherwise adulterate specimens before DNA tests. Personnel responsible for sampling should be aware of this possibility and should try to establish procedures to avoid the problem. 相似文献

Abstract: An online forensic dental identification exercise was conducted involving 24 antemortem–postmortem (AM–PM) dental radiograph pairs from actual forensic identification cases. Images had been digitally cropped to remove coronal tooth structure and dental restorations. Volunteer forensic odontologists were passively recruited to compare the AM–PM dental radiographs online and conclude identification status using the guidelines for identification from the American Board of Forensic Odontology. The mean accuracy rate for identification was 86.0% (standard deviation 9.2%). The same radiograph pairs were compared using a digital imaging software algorithm, which generated a normalized coefficient of similarity for each pair. Twenty of the radiograph pairs generated a mean accuracy of 85.0%. Four of the pairs could not be used to generate a coefficient of similarity. Receiver operator curve and area under the curve statistical analysis confirmed good discrimination abilities of both methods (online exercise = 0.978; UT‐ID index = 0.923) and Spearman’s rank correlation coefficient analysis (0.683) indicated good correlation between the results of both methods. Computer‐aided dental identification allows for an objective comparison of AM–PM radiographs and can be a useful tool to support a forensic dental identification conclusion. 相似文献

Abstract: An LC–MS method was developed for benzylpiperazine (BZP) and trifluoromethylphenylpiperazine (TFMPP), constituents of “party pills” or “legal herbal highs,” and their metabolites in human blood plasma. Compounds were resolved using a mixture of ammonium formate (pH 4.5, 0.01 M) and acetonitrile (flow rate of 1.0 mL/min) with a C18 column. Calibration curves were linear from 1 to 50 ng/mL (R2 > 0.99); the lower limit of quantification (LLOQ) was 5 ng/mL; the accuracy was >90%; the intra‐ and interday relative standard deviations (R.S.D) were <5% and <10%, respectively. Human plasma concentrations of TFMPP were measured in blood samples taken from healthy adults (n = 6) over 24 h following a 60‐mg oral dose of TFMPP: these peaked at 24.10 ng/mL (±1.8 ng/mL) (Cmax) after 90 min (Tmax). Plasma concentrations of 1‐(3‐trifluoromethyl‐4‐hydroxyphenyl) piperazine peaked at 20.2 ng/mL (±4.6 ng/mL) after 90 min. TFMPP had two disposition phases (t½ = 2.04 h (±0.19 h) and 5.95 h (±1.63 h). Apparent clearance (Cl/F) was 384 L/h (±45 L/h). 相似文献

In this study, we randomly assigned 123 sixth and seventh grade classrooms from seven middle schools in the greater Cleveland
area to one of two five-session curricula addressing gender violence/sexual harassment (GV/SH) or to a no-treatment control
group. A baseline survey and two follow-up surveys were administered immediately after the treatment (Wave 2) and about six
months post-treatment (Wave 3). In an earlier paper, we demonstrated the effectiveness of two approaches to youth GV/SH prevention
programming (a fact-based, law and justice curriculum and an interaction-based curriculum). In this paper, we explored whether
these largely positive findings remain for both girls and boys, including whether girls experience higher levels of GV/SH
than boys. Most of our statistical models proved to be non-statistically significant. However, in 2 of our 48 victimization/perpetration
(any violence, sexual violence and non-sexual violence) models (across two post-intervention follow-up points), we observed
that the interventions reduced peer (male or female, non-dating partner) sexual violence victimization and reduced peer perpetration,
but another outcome model indicated that the interventions increased dating perpetration. These mixed findings will need to
be explored further in future research. Regarding our primary research question, we observed no statistically significant
differences for the treatment multiplied by gender interaction terms for any of the perpetration or victimization outcome
models, suggesting that the treatment had similar effects on girls and boys. However, we did observe that boys are more involved
in violence than girls: both as victims and perpetrators. Boys experienced significantly more of three types of victimization
from peers and dating partners compared to what girls experienced at the hands of their peers and dating partners. As perpetrators,
boys committed more sexual victimization against peers (immediately post-intervention only) and more sexual victimization
against dating partners than girls. The implications of these results are discussed. 相似文献

The diagnosis of posttraumatic stress disorder (PTSD) was introduced in 1980 with the publication of the Diagnostic and Statistical Manual of the American Psychiatric Association, Third Edition (DSM-III). DSM-III put forward a novel syndrome consisting of intrusive, avoidance/numbing, and arousal symptoms as distinctive psychopathology following exposure to traumatic events. The traumatic stressors, although expanded in later editions published in 1987 (DSM-III-R) and 1994 (DSM-IV), focus on life-threatening events and situations. However, at least 12 studies, most of them recent, have found associations between the PTSD symptoms and the PTSD symptom syndrome with stressors, such as unemployment and divorce that would not qualify, even in the broadened DSM-IV diagnosis, as traumatic stressors. These findings challenge the basic assumption on which the PTSD diagnosis is based, the assumption that exposure to life-threatening stressors is the primary cause of a unique set of stress response symptoms. The purpose of this paper is to show how to confront this challenge by developing a typology of stressful situations and events that can be tested systematically for their relation to the PTSD symptom syndrome and other relevant variables. The typology includes but is not limited to the types of situations and events defined as "traumatic" in the DSMs. 相似文献

Although sanction threats promote fear, among committed offenders, that fear can become a resource with which to sculpt emerging crime preferences. In such cases, criminality is not deterred but channeled. We explore the channeling process here as it relates to auto theft and carjacking. Our qualitative findings reveal that auto thieves are reluctant to embrace the violence of carjacking due to concerns over sanction threat severity they attributed to carjacking—both formal (higher sentences) and informal (victim resistance and retaliation). Meanwhile, the carjackers are reticent to enact auto theft because of the more uncertain and putatively greater risk of being surprised by victims, a fear that appears to overcome the enhanced long-term formal penalty of taking a vehicle by force. We examine the implications of offenders’ decision-making for the analytic intersection of rational choice and deterrence, offering the notion of projective risk sensitivity to encapsulate the process. 相似文献

The movements of political protest, competitive elections and the installation of new regimes are widely regarded as the most significant political upheaval to shake Africa since political independence. The impression is often given that this transformation has also seen the sweeping away of the old guard of autocratic leaders. The image of renewed leadership does not however correspond with reality. Taking the leaders that were in office in 1990 at the beginning of the democratisation movement, the article traces their subsequent history. It finds that half still hold the highest office, having for the most part successfully transformed themselves into 'democratic' leaders. This remarkable success story is examined, for the purpose of this article, from a voluntarist perspective, that is, the tactics that the incumbents pursued so as to remain in office are the focus. Continuing in the tradition of Sandbrook, and Jackson and Rosberg's work on 'personal rule',1 it constitutes a primer on how to hang on to power against the odds. 相似文献

Abstract Despite its potential policy relevance, public opinion about homelessness has received little attention from researchers. This deficiency is addressed here by bringing together data obtained in four recent surveys. The survey results indicate that many Americans accurately perceive the characteristics of homeless people, consider homelessness a serious problem with structural roots, and support a variety of measures intended to solve it. Certain segments of the public— Democrats, liberals, blacks, and residents of communities that have homeless populations—are especially likely to hold these views. The extent to which the public's thoughts on homelessness have been shaped by the media is difficult to determine. However, an analysis of the volume and content of print and broadcast news coverage of the issue hints at a plausible causal connection. 相似文献
