Frequency and Severity Approaches to Indexing Exposure to Trauma: The Critical Incident History Questionnaire for Police Officers

The Critical Incident History Questionnaire indexes cumulative exposure to traumatic incidents in police by examining incident frequency and rated severity. In over 700 officers, event severity was negatively correlated (rs = -61) with frequency of exposure. Cumulative exposure indices that varied emphasis on frequency and severity-using both nomothetic and idiographic methods-all showed satisfactory psychometric properties and similar correlates. All indices were only modestly related to posttraumatic stress disorder (PTSD) symptoms. Ratings of incident severity were not influenced by whether officers had ever experienced the incident. Because no index summarizing cumulative exposure to trauma had superior validity, our findings suggest that precision is not increased if frequency is weighted by severity

Formality and informality in the summative assessment of motor vehicle apprentices: a case study

This article explores the interaction of formal and informal attributes of competence‐based assessment. Specifically, it presents evidence from a small qualitative case study of summative assessment practices for competence‐based qualifications within apprenticeships in the motor industry in England. The data are analysed through applying an adaptation of a framework for exploring the interplay of formality and informality in learning. This analysis reveals informal mentoring as a significant element which influences not only the process of assessment, but also its outcomes. We offer different possible interpretations of the data and their analysis, and conclude that, whichever interpretation is adopted, there appears to be a need for greater capacity‐building for assessors at a local level. This could acknowledge a more holistic role for assessors; recognise the importance of assessors’ informal practices in the formal retention and achievement of apprentices; and enhance awareness of inequalities that may be reinforced by both informal and formal attributes of assessment practices

Kidnapping and Mental Health in Iraqi Refugees: The Role of Resilience

Although kidnapping is common in war-torn countries, there is little research examining its psychological effects. Iraqi refugees (N = 298) were assessed upon arrival to the U.S. and 1 year later. At arrival, refugees were asked about prior trauma exposure, including kidnapping. One year later refugees were assessed for posttraumatic stress disorder (PTSD) and major depression disorder (MDD) using the SCID-I. Individual resilience and narratives of the kidnapping were also assessed. Twenty-six refugees (9 %) reported being kidnapped. Compared to those not kidnapped, those who were had a higher prevalence of PTSD, but not MDD, diagnoses. Analyses examining kidnapping victims revealed that higher resilience was associated with lower rates of PTSD. Narratives of the kidnapping were also discussed. This study suggests kidnapping is associated with PTSD, but not MDD. Additionally, kidnapping victims without PTSD reported higher individual resilience. Future studies should further elucidate risk and resilience mechanisms

Perceptions of the mental health impact of intimate partner violence and health service responses in Malawi

Background and objectives: This study explores the perceptions of a wide range of stakeholders in Malawi towards the mental health impact of intimate partner violence (IPV) and the capacity of health services for addressing these. Design: In-depth interviews (IDIs) and focus group discussions (FGDs) were conducted in three areas of Blantyre district, and in two additional districts. A total of 10 FGDs, 1 small group, and 14 IDIs with health care providers; 18 FGDs and 1 small group with male and female, urban and rural community members; 7 IDIs with female survivors; and 26 key informant interviews and 1 small group with government ministry staff, donors, gender-based violence service providers, religious institutions, and police were conducted. A thematic framework analysis method was applied to emerging themes. Results: The significant mental health impact of IPV was mentioned by all participants and formal care seeking was thought to be impeded by social pressures to resolve conflict, and fear of judgemental attitudes. Providers felt inadequately prepared to handle the psychosocial and mental health consequences of IPV; this was complicated by staff shortages, a lack of clarity on the mandate of the health sector, as well as confusion over the definition and need for ‘counselling’. Referral options to other sectors for mental health support were perceived as limited but the restructuring of the Ministry of Health to cover violence prevention, mental health, and alcohol and drug misuse under a single unit provides an opportunity. Conclusion: Despite widespread recognition of the burden of IPV-associated mental health problems in Malawi, there is limited capacity to support affected individuals at community or health sector level. Participants highlighted potential entry points to health services as well as local and national opportunities for interventions that are culturally appropriate and are built on local structures and resilience

Online Political Communication Strategies: MEPs, E-Representation, and Self-Representation

Research into the communication strategies of legislators has a long history. The European Parliament offers an opportunity to add to understanding of how legislators prioritize styles of communication, with a comparative perspective across 27 nations. Through content analysis of online communication, we investigate how the Internet is used by members of the European Parliament. Our analysis assesses three communication strategies: homestyle, impression management, and participatory. We find that a homestyle strategy predominates, followed by impression management. Participatory communication is emergent, but may earn legislators political capital, as it appears that proactive communicators who offer participatory opportunities are more likely to build an online following

Equilibrium configurations of two charged masses in General Relativity

An asymptotically flat static solution of Einstein-Maxwell equations which describes the field of two non-extreme Reissner - Nordstr\"om sources in equilibrium is presented. It is expressed in terms of physical parameters of the sources (their masses, charges and separating distance). Very simple analytical forms were found for the solution as well as for the equilibrium condition which guarantees the absence of any struts on the symmetry axis. This condition shows that the equilibrium is not possible for two black holes or for two naked singularities. However, in the case when one of the sources is a black hole and another one is a naked singularity, the equilibrium is possible at some distance separating the sources. It is interesting that for appropriately chosen parameters even a Schwarzschild black hole together with a naked singularity can be "suspended" freely in the superposition of their fields.Comment: 4 pages; accepted for publication in Phys.

Loss, Bereavement and Creativity: Meanings and Uses

Within the field of death and bereavement studies, the assumption that loss and bereavement provide the spur to creativity has become so widespread as to assume the status of a conventional wisdom. With this in mind, this article surveys the literature on the topic, extant, and contemporary, revealing its diffuseness as well as the multidisciplinary synergies produced by those working in disparate academic and clinical fields of practice. In so doing, the article explores what it means to be creative in the context of loss and bereavement, the potential for self-development and personal growth offered by creativity and loss, the theoretical premises linking creativity and loss, and the application and challenges for creative therapies in the institutional context of hospice and palliative car
