The article describes characteristics of pregnant women presenting to the Emergency Department (ED) who are experiencing current violence and presented a screening tool to identify pregnant women experiencing violence. Women completed an in-person interview regarding violence, sociodemo-graphic factors, health status, and drug use. Fifteen percent of women reported at least one episode of violence during the pregnancy. Young age (OR = 3.37, 95% CI: 1.79-6.36), current alcohol use (OR = 1.53, 95% CI: 1.06-2.19), current marijuana use (OR = 1.96, 95% CI: 1.32-2.92), less than a high school education (OR = 1.46, 95% CI: 1.01-2.12), and a prior diagnosis of trichomonas (OR = 1.81, 95% CI: 1.20-2.72) were significantly related to experiencing current violence. Screening patients using these five characteristics identified 8 out of 10 women reporting violence (sensitivity = 75.6%). These results identify a set of predictors that may be helpful in identifying pregnant women who are experiencing current domestic violence.  相似文献

Prior event-based research regarding the relationship between alcohol and violence suffers from important limitations, including the absence of a comparison group, an inappropriate comparison group, or a comparison group that could be considered appropriate but does not control for potential confounders. To overcome such limitations, we use a matched pair design. Drawing on interviews with men imprisoned for an aggravated assault or homicide committed in response to a conflict with another man, we examine matched pairs of violent and nonviolent conflicts nested within respondents. The results suggest that guns mediate the relationship between alcohol and lethal male-male violence.  相似文献

The expansion of indigenous art and the interest it has generated both at a domestic and international level means large monetary transactions are taking place between art galleries or centers and purchasers. As such, an accurate and conclusive method for provenance determination of traditional indigenous artistic materials must be established that can, if necessary, be used to assist in authentication of artworks. Laser ablation inductively coupled plasma mass spectrometry was utilized for elemental differentiation and provenance establishment of ocher samples. This research was used to develop a robust scientific protocol which facilitates definitive and accurate determination of provenance of Australian ochers and the artworks created using them. Analysis of the results obtained through this study show that the trace metal distribution patterns alone appear to be sufficient evidence to establish provenance of specific ochers, although additional differentiation between ocher samples, using major element distribution patterns, was achieved through the utilization of X-ray analytical techniques.  相似文献

We tested the hypothesis that beliefs in the purported attributes of recovered memories of child sexual abuse (CSA) are associated with knowledge of the "recovered/false memory debate", and that such beliefs will be related to assessments of the credibility of statements made by participants in a vignette about CSA. Participants from five countries (the United States, Canada, New Zealand, the United Kingdom and Israel) responded to a questionnaire regarding beliefs about recovered memory as well as self-reported exposure to and knowledge of the debate. In addition, they assessed the credibility of statements made by a daughter (reporting recovery of memories of sexual abuse by her father), her father (denying the allegation and accusing the daughter's therapist of implanting in her false "memories" of abuse), and two experts (each supporting one of the two protagonists). We found that prior knowledge of the debate across countries was linked to beliefs in specific attributes of recovered memories and to a subset of the credibility assessments of statements made by the protagonists and their experts. For individuals, however, credibility assessments were unrelated to knowledge of the debate, but they were related to beliefs about memory recovery. Finally, credibility of the protagonists' statements was differentially associated with those made by the daughter's and the father's experts. The results suggest that whereas familiarity with the debate does not affect the credibility of the statements made by the complainant and the accused, expert testimony does, as has been found in prior research. The psycholegal implications of this conclusion are discussed.  相似文献

Drug screening methods were developed to detect alprazolam, clobazam, clonazepam, diazepam, midazolam, oxazepam, temazepam, triazolam, zopiclone, and selected metabolites in human hair and nail samples employing liquid-liquid extraction and tandem liquid chromatography-mass spectrometry (LC-MS-MS). Hair and nail samples were obtained from patients who had recently discontinued or were currently prescribed one or more of the targeted drugs. Prazepam was used as the internal standard for all compounds. Some components in the hair matrix gave the same transitions as some of the analytes but did not compromise the analyses because their retention times differed from those for the target compounds. The analytical run time was 8-10min. Results of the hair analysis of a DFSA victim are also presented.  相似文献

Using the case of education, we consider how global cultural and economic forces affect national education spending policies. Our analysis includes both an historical analysis of the construction and transformation of ideas about education at the global level and a statistical assessment of the implementation of conflicting approaches to state education funding within countries. In the historical analysis, we show how the idea of free education, although institutionalized in international law, was subject to powerful challenges from international financial institutions, which advocated user fees for public services, including education. Ultimately, the principle of free education prevailed despite the financial clout behind the opposing view. Using data from poor‐ and middle‐income countries from 1983 to 2004, we also show that the presence of international nongovernmental organizations (INGOs) advocating child rights was linked to an increase in the levels of state funding for education. This suggests that embeddedness in global discourses, as evidenced by country‐specific linkages to INGOs, is critical in making governments more accountable for supporting institutionalized ideas concerning education.  相似文献

Betrayal trauma, or trauma perpetrated by someone with whom a victim is close, is strongly associated with a range of negative psychological and physical health outcomes. However, few studies have examined associations between different forms of trauma and emotional and physical symptoms. The present study compared betrayal trauma to other forms of trauma as predictors of young adults' psychological and physical symptoms, and explored potential mediators. A total of 185 university undergraduate students completed the Brief Betrayal Trauma Survey, the Trauma Symptom Checklist, the Toronto Alexithymia Scale, and the Pennebaker Inventory of Limbic Languidness. For each set of symptoms, simultaneous multiple regressions assessed the relative contributions of low versus high betrayal trauma to psychological and physical health reports. Structural equation models examined traumatic stress symptoms and alexithymia as mediators of the relationship between betrayal trauma and physical health symptoms. A total of 151 participants (82%) reported exposure to at least 1 of 11 forms of trauma queried (M = 2.08, SD = 1.94); 96 participants (51.9%) reported at least 1 betrayal trauma. Traumas characterized by high betrayal predicted alexithymia, anxiety, depression, dissociation, physical health complaints, and the number of days students reported being sick during the past month, whereas other traumas did not. Structural equation modeling revealed that traumatic stress symptoms and alexithymia mediated the association between betrayal trauma and physical health complaints. These results indicate that betrayal trauma is associated with young adults' physical and mental health difficulties to a greater extent than are other forms of trauma. Results may inform assessment, intervention, and prevention efforts.  相似文献

Very little attention has been paid to both partners beliefs about why violence in their previously abusive relationship has stopped or significantly reduced despite well-documented details in the research literature outlining the characteristics of both victims and perpetrators. This study aimed to provide some understanding of how each partner believed that the violence has ended. However their answers often were not definitive; instead, they uncovered the complexities in their relationship and their struggle to overcome the uncertainty they have to achieve and maintain successful remediation. The article is based on a qualitative Interpretative Phenomenological Analysis (IPA) study that explored the nature of the relationship between six heterosexual couples before and after a therapeutic intervention for the men perpetrators, which followed the Duluth Model. The study included how they both understood the violence and how they maintained nonviolence in their relationship. The men were notably still in the process of reprocessing their understanding of why they were violent and they needed to further understand their reactions to maintain their nonviolence. The IPA themes provided some understanding of how the participants thought they had a better understanding of the factors that had maintained their relationship since the termination of the intervention. The themes, generated from the interviews provided by the perpetrators and their victims, are explored and some explanations for the successful continuation of their relationship following treatment are suggested. Implications for widening the treatment options for men perpetrators are suggested in addition to providing treatment options for couples who wish to remain within their relationships and need help to identify unhelpful and dangerous patterns of interaction.  相似文献
