Intimate partner violence (IPV), an international public health matter, is linked to psychological distress including suicidal behavior. Despite the noted sequelae associated with IPV, many individuals display resilience in the face of IPV exposure. This study examines two potential protective factors in the IPV-suicidal ideation link, namely existential and religious well-being, in a sample of African American women. Low-income, African American, female suicide attempters who were abused by a partner within the previous year (N?=?111) were administered the Conflicts Tactics Scale-2, Spiritual Well-Being Scale, and Beck Scale for Suicide Ideation. Mediational models testing indirect effects through the bootstrapping method revealed that the total effect of IPV on suicidal ideation was positive and significant, confirming suicidal ideation as a consequential outcome of IPV among African American women. This effect was mediated by existential well-being; however, religious well-being was not a significant mediator, suggesting that existential well-being serves a unique protective role in the IPV-suicidal ideation relation. The results provide additional support for the well-known positive effects of existential well-being on mental health among African American samples. Culturally-informed, meaning-making interventions to enhance existential well-being appear to be effective in reducing suicidal ideation in this population.  相似文献

The current meta-analysis compared younger and older adult eyewitness identification accuracy and includes analyses designed to determine what witness and event factors might moderate any differences found. Results showed that, regardless of lineup type and perpetrator age, older eyewitnesses are reliably worse at making correct lineup decisions than younger eyewitnesses whether they are identifying perpetrators or rejecting perpetrator-absent lineups. Discussion of possible causes for this difference in identification accuracy is drawn from cognitive and social psychology literatures, and possible implications for future research and public policy are put forth.  相似文献

Placement stability is of critical importance to the well-being of children in foster care and has an impact on other key outcomes. Placement decision-making that matches children with placement resources is often cited as a practice that impacts placement stability, but little research exists to inform this practice. The focus of this research is on a child assessment tool that was developed to determine the appropriate level of care, which serves as one component of a web-based matching system that pulls together child and placement information used to inform the placement decision. The research examines the relationship between the child assessment subscale domains and placement stability for first and subsequent placement decisions and evaluates the stability of placements made in and outside of the indicated level of care.  相似文献

This essay is concerned to trace a materialist current within the work of Peter Goodrich, with the aim of evaluating it in the light of the work of Deleuze and Guattari. The are two reasons for this: firstly, it serves to encourage the development of Deleuzean perspectives within critical legal studies, and secondly, it presents the potential of a re-invigoration of a branch of criticism based not only upon the problems raised by issues of meaning and representation, but one which is also sensitive to the conditions of the relations of production of both meaning and desire. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

Synthetic cannabinoids are sprayed onto plant material and smoked for their marijuana‐like effects. Clandestine manufacturers modify synthetic cannabinoid structures by creating closely related analogs. Forensic laboratories are tasked with detection of these analog compounds, but targeted analytical methods are often thwarted by the structural modifications. Here, direct analysis in real time coupled to accurate mass time‐of‐flight mass spectrometry (DART‐TOF‐MS) in combination with liquid chromatography quadruple time‐of‐flight mass spectrometry (LC‐QTOF‐MS) are presented as a screening and nontargeted confirmation method, respectively. Methanol extracts of herbal material were run using both methods. Spectral data from four different herbal products were evaluated by comparing fragmentation pattern, accurate mass and retention time to available reference standards. JWH‐018, JWH‐019, AM2201, JWH‐122, 5F‐AKB48, AKB48‐N‐(4‐pentenyl) analog, UR144, and XLR11 were identified in the products. Results demonstrate that DART‐TOF‐MS affords a useful approach for rapid screening of herbal products for the presence and identification of synthetic cannabinoids.  相似文献
