The accurate quantification of target DNA is an important step in the short tandem repeat analysis of forensic biological samples. By utilizing quantification data to control the amount of template DNA in the polymerase chain reaction (PCR), forensic scientists can optimize testing and minimize the consumption of limited samples. The ability to identify and quantify target DNA in mixed-species samples is crucial when it may be overwhelmed by nontarget DNA, as in cases of dog attack. We evaluated two quantitative real-time PCR assays for dynamic range, species specificity, and inhibition by humic acid. While both assays proved to be highly sensitive and discriminating, the Melanocortin-1 Receptor (MC1R) gene Taqman assay had the advantages of a shorter run time, greater efficiency, and safer reagents. In its application to forensic casework, the MC1R assay has been advantageous for quantifying dog DNA in a variety of mixed-species samples and facilitating the successful profiling of individual dogs. 相似文献

It is thought that deaf or hard of hearing individuals are at greater risk of abuse than the hearing population. The purpose of this paper is to systematically examine and integrate existing literature to determine the prevalence rates of neglect, emotional, physical and sexual abuse and intimate partner violence (IPV). A set of inclusion and exclusion criteria was determined. Following this a comprehensive search of numerous databases was conducted. Fourteen studies met the inclusion criteria. Eight studies reviewed the prevalence of sexual abuse, seven reviewed physical abuse, five reviewed emotional abuse, four reviewed neglect and six examined IPV. This exceeds 14 as numerous studies examined multiple types of abuse. Quality assessment indicated 12 studies were of ‘moderate’ quality and the remaining two were rated ‘good’ quality. Issues with similar samples, a tendency towards young, educated women within the IPV data, and small samples suggest caution is to be used when interpreting their results. The reliance on written measures and the absence of an interpreter or translation of materials in some studies further complicates the results. All types of abuse were found to be more prevalent within the deaf and hard of hearing population compared to the hearing population. 相似文献

The purpose of this study is to examine the permanency experiences of older youth, age 18–21 in out-of-home placements and placement characteristics that influence age of exit from child welfare. Findings suggest a difference between age groups with more 18-year old youth exiting to emancipation than youth who exit at age 21. A higher number of spells in care and a higher number of placement changes during the last spell were associated with exit to emancipation. Additional study findings suggests that youth who leave care before the age of 21 may be more vulnerable than youth who stay through age 21. Implications for practice are discussed. 相似文献

Parochial schools are assumed to provide better social and academic experiences; however, few studies account for selection bias when comparing with public schools. This study contrasted public versus parochial schools using propensity score matching across a range of outcomes (e.g., perceptions of school, emotional symptoms, substance use, bullying). Using a sample of 58 public and 5 parochial high schools, the nonmatched analyses suggested a significant advantage for parochial schools students (e.g., better on 23 of 32 indicators). However, the propensity score matched analyses revealed nine differences (e.g., weapon carrying, smoking), two of which (i.e., stress and cyberbullying) favored public schools. While at first glance parochial schools generally appear to be healthier and safer learning environments, accounting for selection bias, the gap was narrowed. Students in parochial schools may struggle with issues related to social, emotional, and behavioral health risk, and thus prevention programs should also be implemented in these settings. 相似文献

Posttraumatic stress disorder (PTSD) is arguably prone to malingering due to its subjective and heterogeneous nature. Various factors can influence PTSD symptom profiles including trauma type and trauma exposure. However, it is unknown whether trauma exposure influences malingered PTSD symptom profiles. We used a malingering simulation design with trauma type controlled to compare (1) PTSD symptom profiles (Posttraumatic Stress Checliklist-5; PCL-5) at the syndrome, symptom cluster, and individual symptom levels and (2) symptom validity profiles (Structured Inventory of Malingered Symptomatology; SIMS) at the overall and subscale level, as a function of direct and indirect trauma exposure. Seventy-three participants were randomly assigned to either the direct (“witnessed” trauma) or indirect (“learned about” trauma) condition. Participants were coached about symptoms and instructed to simulate PTSD. PCL-5 profile analyses revealed that simulators in the direct exposure group reported greater overall PTSD severity. Significant differences were found on cluster D (changes in cognition and mood) and individual symptoms including intrusive thoughts, amnesia, difficulty experiencing positive emotions, and risk-taking. No differences were identified for any other symptom scores nor for the symptom validity profile, except for the SIMS total score (direct: M?=?33.0, SD?=?12.8, indirect: M?=?26.5, SD?=?13.9, t(71)?=?2.06, p?=?.043, d?=?.48). These findings indicate that trauma exposure can influence malingered PTSD profiles at the syndrome, symptom cluster, and individual symptom levels (small effects), but, with one exception for a summary score, it does not produce a detectable difference on symptom validity testing. This study may provide insight for clinicians into the how malingered PTSD profiles can manifest as a result of direct and indirect trauma exposure; however, further research is strongly indicated. 相似文献

Educational attainment is a fundamental cornerstone to success throughout the life-course. As a result, ensuring that young people remain in school and are not truant is critical. Although the importance of truancy as a risk factor for many adverse outcomes, including crime, has been well-documented, much less methodologically rigorous work has been undertaken to evaluate potentially promising prevention and intervention strategies. This paper uses a randomized field trial method to test how a partnership between police and schools targeting truancy impacts offending in a sample of high-risk truanting young people. We find that the truancy intervention reduces offending and we discuss the implications for practice and directions for future research. 相似文献

Objectives
To systematically review and quantitatively synthesize the evidence for the impact of parenting interventions for incarcerated parents on parenting knowledge and skills, parent well-being, and quality of the parent–child relationship.Methods
A systematic search of 19 published and unpublished literature sources was conducted between June and July 2015 (with no date, language, document type, or geographical restrictions). Studies were included if they: (a) utilized a sample of parents who completed a parenting intervention in an incarceration setting; (b) measured parenting knowledge and skills, parent well-being, or quality of the parent–child relationship as outcome measures; and (c) employed a randomized controlled trial or quasi-experimental design with no treatment, waitlist control, or treatment-as-usual as the comparison condition. Two review authors independently determined study eligibility and extracted data from eligible studies, which included rating the risk of bias for each eligible study. Meta-analysis was used to synthesize standardized effect sizes, and subgroup analyses were used to examine the moderating effect of parent gender, level of child involvement, and research design.Results
Twenty-two studies were eligible for inclusion in the review; however, only 16 studies (N = 2292) reported sufficient data for inclusion in the meta-analyses. Parenting interventions were more effective at post-intervention for improving parenting knowledge and skills than no treatment, waitlist control, or treatment-as-usual [standardized mean difference (SMD) = 0.68, 95% confidence interval (CI) 0.28, 1.06] and quality of the parent–child relationship (SMD = 0.27, 95% CI 0.02, 0.51), but not for improving parent well-being (SMD = 0.14, 95% CI ?0.03, 0.30). There was significant heterogeneity across effect sizes for both parenting knowledge and skills and quality of the parent–child relationship outcome domains. There were no statistically significant differences between subgroups, and the effectiveness of parenting interventions was not maintained at follow-up time-points.Conclusions
Existing evidence suggests small to moderate effectiveness for parenting interventions during incarceration at close to intervention completion. Further methodologically robust research is required to more confidently establish the effectiveness of parenting programs both in the short-term and in the post-release period.188.

A study is presented which investigated aspects of a specialist method for taking evidence from witnesses known as ‘Cognitive Interviewing’. Specifically, the study sought to evaluate four techniques used in this form of interviewing, namely the Report All, Reinstate Context, Change Order, and the Change Perspectives mnemonics. The findings suggest that while none of these mnemonics significantly increased inaccuracy, all but the Change Perspectives mnemonic facilitated recall of accurate information. The findings are discussed in terms of the applied functional utility of each of the mnemonics and the Cognitive Interview procedure in general. 相似文献

Abstract Prior to starting a pro-feminist domestic violence rehabilitation programme, 120 British male domestic violence offenders completed psychometric and attitudinal measures that assessed pro-domestic violence attitudes, anger, locus of control, self-reported emotional and psychological abuse of a partner, interpersonal dependency and social desirability. Offenders who completed the programme were compared to those who dropped out on these measures and demographic variables. Just under one-third (32.5%) of offenders failed to complete the programme. Of those variables that discriminated between completers and dropouts (age, previous custodial sentences, age at first conviction, marital status, self-reported abuse, and diagnosis of depression), only age (being young), having previously received a custodial sentence and self-reported low levels of physical abuse of a partner predicted attrition. These results are discussed with reference to probation supervision. 相似文献
