Genetically informative samples can address hereditary and experiential influences on suicide‐related behaviors. The frequency of suicide‐related behaviors was compared in twins from two survivor groups: (1) those whose co‐twins' deaths were suicides (monozygotic [MZ]: n = 47; dizygotic [DZ]: n = 31), and (2) those whose co‐twins' deaths were nonsuicides (MZ: n = 347; DZ: n = 170). The frequency of suicide attempts among suicide survivors was significantly higher in MZ than DZ twins, while the frequency of suicide attempts among nonsuicide twin survivors did not differ between MZ and DZ twins. Twin concordance for suicide attempts more likely reflects a genetic predisposition than a behavioral reaction to the loss.  相似文献

The Cognitive‐Emotional Theory of Esteem Support Messages posits that messages intended to enhance recipients' state self‐esteem focus on cognitions and/or behaviors. In the current studies, problem‐focused message content (i.e., content focused on enacting behavior to alleviate the esteem threat) was of particular interest. College students (Study 1, n= 227) applying for postgraduation jobs and unemployed, underemployed, and/or displaced workers recruited from a government one‐stop career center (Study 2, n = 292) rated esteem support messages varying in degree of focus on behaviors vs. cognitions relevant to the job search process. Messages focused on behavior were rated as less effective than those focusing on cognitions relevant to the esteem threat, although support for this result was stronger in Study 2.  相似文献

Adolescents experiencing social anxiety often engage in safety behaviors―covert avoidance strategies for managing distress (e.g., avoiding eye contact)―that factor into the development and maintenance of their concerns. Prior work supports the psychometric properties of the Subtle Avoidance Frequency Examination (SAFE), a self-report survey of safety behaviors. Yet, we need complementary methods for assessing these behaviors within contexts where adolescents often experience concerns, namely, interactions with unfamiliar peers. Recent work indicates that, based on short, direct social interactions with adolescents, individuals posing as unfamiliar peers (i.e., peer confederates) and without assessment training can capably report about adolescent social anxiety. We built on prior work by testing whether we could gather valid SAFE reports from unfamiliar untrained observers (UUOs), who observed adolescents within archived recordings of these short social interactions. A mixed clinical/community sample of 105 adolescents self-reported on their functioning and participated in a series of social interaction tasks with peer confederates, who also provided social anxiety reports about the adolescent. Based on video recordings of these tasks, trained independent observers rated adolescents’ observed social skills, and an additional set of UUOs completed SAFE reports of these same adolescents. Unfamiliar untrained observers’ SAFE reports (a) related to adolescents’ SAFE self-reports, (b) distinguished adolescents on clinically elevated social anxiety concerns, (c) related to trained independent observers’ ratings of adolescent social skills within interactions with peer confederates, and (d) related to adolescents’ self-reported arousal within these same interactions. Our findings support use of unfamiliar observers’ perspectives to understand socially anxious adolescents’ interpersonal functioning.  相似文献

Serious academic reflection and scholarship on the Fresh Expressions of Church (FXoC) movement in the United Kingdom is developing significantly, but there exists almost no such work in South Africa. What has been produced deals with scholars reflecting on their experiences of Fresh Expressions in the United Kingdom (Ian Nell and Rudolph Grobler, “An Exploration of Fresh Expressions as Missional Church: Some Practical-Theological Perspectives,” NGTT DEEL 55:3–4 (2017), 747–68). This is an unfortunate situation. While there has been a generous response by many churches, there has been little interest, by and large, from the Anglican Church of Southern Africa (ACSA). FXoC is, then, an under-researched entity in South Africa. This article, part of a larger study, seeks to ask questions about how liturgy might develop from below in a new ecclesial community of marginalized people.  相似文献

In jurisdictions throughout the United States, thousands of sexual assault kits (SAKs; also known as a “rape kits”) have not been submitted by the police for forensic DNA testing. DNA evidence may be helpful to sexual assault investigations and prosecutions by identifying perpetrators, revealing serial offenders through DNA matches across cases, and exonerating those who have been wrongly accused. This paper describes a longitudinal action research project conducted in Detroit, Michigan after that city discovered approximately 11,000 untested sexual assault kits in a police department storage facility. We conducted a root cause analysis to examine individual, organizational, community, and societal factors that contributed to the development of the rape kit backlog in Detroit. Based on those findings, we implemented and evaluated structural changes to increase staffing, promote kit testing, and retrain police and prosecutors so that cases could be reopened for investigation and prosecution. As we conducted this work, we also studied how this action research project impacted the Detroit criminal justice system. Participating in this project changed stakeholders’ attitudes about the utility of research to address community problems, the usefulness of DNA evidence in sexual assault cases, and the impact of trauma on survivors. The results led to new protocols for SAK testing and police investigations, and new state legislation mandating SAK forensic DNA testing.  相似文献
