Social support, self-efficacy, trauma and well-being in emergency medical dispatchers

Emergency Medical Dispatchers (EMDs) respond to crisis calls for ambulance; they dispatch paramedics and provide emotional and medical assistance to callers. Despite the stressful nature and exposure to potentially traumatising events in this role, there has been no published research specifically investigating well-being or posttraumatic growth among EMDs. Extrapolating from research conducted among other emergency services workers (e. g., paramedics, police), literature attests to the importance of self efficacy and social support in promoting mental health in emergency service workers. Therefore, this study assessed the impact of self efficacy, and giving and receiving social support on psychological well-being, posttraumatic growth (PTG), and symptoms of posttraumatic stress disorder (PTSD). Sixty EMDs (50% response rate) completed an online questionnaire. Three hierarchical multiple regression analyses were conducted to ascertain predictors of well-being, PTG and PTSD. Receiving social support emerged as a significant positive predictor of well-being and PTG, and a significant negative predictor of PTSD. Self efficacy was found to significantly and positively predict well-being, and shift-work was found to significantly and negatively predict PTSD. These results highlight that self efficacy and receiving social support are likely to be important for enhancing well-being within this population, and that receiving social support is also likely to facilitate positive post-trauma responses. Such findings have implications for the way emergency service personnel are educated with reference to aspects of mental health and how best to support personnel in order to achieve optimal mental health outcomes for all.

The social foundations of risk

Ulrich Beck's argument about risk society emphasises, among other things, the pervasiveness of risk. As a feature of the human condition in the contemporary, globalised, world that distinguishes the present from the past, risk is widespread across society and affects all social strata. While Beck has gestured towards the irregular distribution of contemporary risks, nonetheless he has suggested that traditional structural entities – class and wealth – no longer provide the key interpretive frameworks for the calculation of susceptibility. In short, the tentacles of risk are long and almost no one is out of reach. Yet, while the risk society thesis has generated a large theoretical literature, there is very little in the way of research that marries theorising to original data collection. This paper represents an attempt to address this gap by using empirical data to investigate whether risk is more textured than Beck's account suggests. Focusing on health as a domain of risk, the paper uses data from a national sample survey of the Australian electorate to investigate the extent to which social divisions structure perceptions of risk within the general population. The findings suggest that various aspects of social stratification, such as income, occupation and education, do indeed play a role in shaping perceptions of risk.

Choice impulsivity: Definitions, measurement issues, and clinical implications

Background Impulsivity critically relates to many psychiatric disorders. Given the multifaceted construct that impulsivity represents, defining core aspects of impulsivity is vital for the assessment and understanding of clinical conditions. Choice impulsivity (CI), involving the preferential selection of smaller sooner rewards over larger later rewards, represents one important type of impulsivity. Method The International Society for Research on Impulsivity (InSRI) convened to discuss the definition and assessment of CI and provide recommendations regarding measurement across species. Results Commonly used preclinical and clinical CI behavioral tasks are described, and considerations for each task are provided to guide CI task selection. Differences in assessment of CI (self-report, behavioral) and calculating CI indices (e.g., area-under-the-curve, indifference point, steepness of discounting curve) are discussed along with properties of specific behavioral tasks used in preclinical and clinical settings. Conclusions The InSRI group recommends inclusion of measures of CI in human studies examining impulsivity. Animal studies examining impulsivity should also include assessments of CI and these measures should be harmonized in accordance with human studies of the disorders being modeled in the preclinical investigations. The choice of specific CI measures to be included should be based on the goals of the study and existing preclinical and clinical literature using established CI measures.

Maternal psychological distress mediates the relationship between asthma and physician visits in a population-based sample of adolescents

Objective This study examined whether maternal psychological distress mediates the relationship between presence of adolescent asthma and number of physician visits, and whether the association between maternal psychological distress and physician visits is moderated by adolescent general health. Methods Data were obtained from the Mater University Study of Pregnancy and included 4025 adolescents. Path analysis was used to examine mediating and moderating effects. Results Maternal psychological distress was found to partially mediate the relationship between adolescent asthma and number of physician visits, accounting for 25% of the effect of adolescent asthma on physician visits (p = .046). There was no evidence to suggest that adolescent general health moderated the association between maternal psychological distress and physician visits (p = .093). Conclusions The findings suggest that maternal psychological distress is associated with increased physician visits, regardless of adolescents' general health. Lowering maternal psychological distress may serve to reduce health care utilization and costs among adolescents with asthma.

Uneducated : play becomes artwork, artwork becomes play

Over the past twenty years the contemporary art world has seen a significant shift in the modes and structures of connection between work and its audiences. This shift is termed by Irit Rogoff, amongst others, as an ‘educational turn’. The turn has been described as the eruption of discussions and investigations, inside and outside of institutions, that interrupt the presumed power hierarchies and bureaucratised systems of both art and education. This essay was written to accompany artist/curator Kym Maxwell's exhibition project, 'Uneducated', exploring these ideas. It was held at the Counihan Gallery in Melbourne, 2014.

The psychological and economic factors that influence energy consumption habits of low-income earners

Social marketers and governments have often targeted hard to reach or vulnerable groups (Gordon et al., 2006) such as young adults and low income earners. Past research has shown that low-income earners are often at risk of poor health outcomes and diminished lifestyle (Hampson et al., 2009; Scott et al., 2012). Young adults (aged 18 to 35) are in a transition phase of their life where lifestyle preferences are still being formed and are thus a useful target for long-term sustainable change. An area of focus for all levels of government is the use of energy with an aim to reduce consumption. There is little research to date that combines both of these groups and in particular in the context of household energy usage. Research into financially disadvantaged consumers is challenging the notion that that low income consumer purchasing and usage of products and services is based upon economic status (Sharma et al., 2012). Prior research shows higher income earners view items such as televisions and computers as necessities rather than non-essential (Karlsson et al., 2004). Consistent with this is growing evidence that low income earners purchase non-essential, energy intensive electronic appliances such as multiple big screen TV sets and additional refrigerators. With this in mind, there is a need for knowledge about how psychological and economic factors influence the energy consumption habits (e.g. appliances on standby power, leaving appliances turned on, running multiple devices at one time) of low income earners. Thus, our study sought to address the research question of: What are the factors that influence young adult low-income earners energy habits?

Regulatory focus moderates the relationship between task control and physiological and psychological markers of stress : a work simulation study

This experiment examined whether trait regulatory focus moderates the effects of task control on stress reactions during a demanding work simulation. Regulatory focus describes two ways in which individuals self-regulate toward desired goals: promotion and prevention. As highly promotion-focused individuals are oriented toward growth and challenge, it was expected that they would show better adaptation to demanding work under high task control. In contrast, as highly prevention-focused individuals are oriented toward safety and responsibility they were expected to show better adaptation under low task control. Participants (N = 110) completed a measure of trait regulatory focus and then three trials of a demanding inbox activity under either low, neutral, or high task control. Heart rate variability (HRV), affective reactions (anxiety & task dissatisfaction), and task performance were measured at each trial. As predicted, highly promotion-focused individuals found high (compared to neutral) task control stress-buffering for performance. Moreover, highly prevention-focused individuals found high (compared to low) task control stress-exacerbating for dissatisfaction. In addition, highly prevention-focused individuals found low task control stress-buffering for dissatisfaction, performance, and HRV. However, these effects of low task control for highly prevention-focused individuals depended on their promotion focus.

Longing band play at beautiful hope

This article enquires into the contextual dimensions of Indonesian consumerism by presenting the rise to national fame of provincial boy band, Kangen (Longing) Band. The case of Kangen Band suggests that Indonesian consumerism entails new ways of heralding the masses that rely on and play with old generic terms, kampungan (hick-ish) and ‘Melayu’ (Malay). It also reveals some of the specificities of the Indonesian consumerist environment, in which ring back tones, pirate recordings and corporatized fandom are important resources in the formation of consumer subjectivities.

The current state of play in human neural stem cell models : what we have learnt from the rodent

Rodent (mouse and rat) models have been crucial in developing our understanding of human neurogenesis and neural stem cell (NSC) biology. The study of neurogenesis in rodents has allowed us to begin to understand adult human neurogenesis and in particular, protocols established for isolation and in vitro propagation of rodent NSCs have successfully been applied to the expansion of human NSCs. Furthermore, rodent models have played a central role in studying NSC function in vivo and in the development of NSC transplantation strategies for cell therapy applications. Rodents and humans share many similarities in the process of neurogenesis and NSC biology however distinct species differences are important considerations for the development of more efficient human NSC therapeutic applications. Here we review the important contributions rodent studies have had to our understanding of human neurogenesis and to the development of in vitro and in vivo NSC research. Species differences will be discussed to identify key areas in need of further development for human NSC therapy applications.

Mirror neuron activation is associated with facial emotion processing

Theoretical accounts suggest that mirror neurons play a crucial role in social cognition. The current study used transcranial-magnetic stimulation (TMS) to investigate the association between mirror neuron activation and facialemotion processing, a fundamental aspect of social cognition, among healthy adults (n = 20). Facial emotion processing of static (but not dynamic) images correlated significantly with an enhanced motor response, proposed to reflect mirror neuron activation. These correlations did not appear to reflect general facial processing or pattern recognition, and provide support to current theoretical accounts linking the mirror neuron system to aspects of social cognition. We discuss the mechanism by which mirror neurons might facilitate facial emotion recognition.

Rupturing otherness : becoming Estonian in the context of contemporary Britain

While identity construction continues to be a widely discussed and researched area in contemporary social sciences, the existing theories have overlooked the importance of understanding why and how identities as semiotic constructions emerge in individuals' consciousness in the flow of their everyday functioning. This article seeks to address this limitation in the theorizing by proposing an alternative conceptualization of identity, according to which identity construction is triggered by rupturing life-experience, which surfaces another perspective and makes the person aware of a possibility to be otherwise or of the reality of being different. Theoretical claims put forward in the paper are drawn from data gathered in a recent study, which explored lived-through experiences of young Estonians, who made study-visits to the United Kingdom. The discussed data will also highlight some interesting aspects in Estonians' self-definition as it is constructed in relation to Eastern-European identity in the context of contemporary Britain.

Gold nanospikes based microsensor as a highly accurate mercury emission monitoring system

Anthropogenic elemental mercury (Hg0) emission is a serious worldwide environmental problem due to the extreme toxicity of the heavy metal to humans, plants and wildlife. Development of an accurate and cheap microsensor based online monitoring system which can be integrated as part of Hg0 removal and control processes in industry is still a major challenge. Here, we demonstrate that forming Au nanospike structures directly onto the electrodes of a quartz crystal microbalance (QCM) using a novel electrochemical route results in a self-regenerating, highly robust, stable, sensitive and selective Hg0 vapor sensor. The data from a 127 day continuous test performed in the presence of volatile organic compounds and high humidity levels, showed that the sensor with an electrodeposted sensitive layer had 260% higher response magnitude, 3.4 times lower detection limit (,22 mg/m3 or ,2.46 ppbv) and higher accuracy (98% Vs 35%) over a Au control based QCM (unmodified) when exposed to a Hg0 vapor concentration of 10.55 mg/m3 at 1016C. Statistical analysis of the long term data showed that the nano-engineered Hg0 sorption sites on the developed Au nanospikes sensitive layer play a critical role in the enhanced sensitivity and selectivity of the developed sensor towards Hg0 vapor.

Development of an online role-play assessment initiative for nursing students in their bioscience studies

Devising assessment tasks for large units that embrace academic goals of authenticity and assessment variety can be a challenge. We developed an online Role-Play Assessment Initiative for first year nursing students in bioscience. Students responded to a case study by preparing two role-play dialogues: as a nurse with the patient, and between two nurses. The aims were to assess whether the students could: 1) understand the underlying disease process (pathophysiology) and relate it to clinical practice; 2) use language appropriate for lay and medical conversation; and 3) apply information using active learning. We conducted a student survey using quantitative questions (Likert scale: 1=strongly disagree to 5=strongly agree), and qualitative questions. 65 completed surveys were received. 80% of respondents agreed (includes agree or strongly agree) that it was a useful way to learn and understand pathophysiology of the case study. 86% agreed that it was useful to apply pathophysiology from lectures to a clinical setting. Overall, students found it enjoyable, which is beneficial for enhanced student engagement, and agreed that it allowed them to work well in a group (74% and 85%, respectively). Most qualitative suggestions for improvement related to group work, despite the encouraging response to group work in quantitative questions. Most positive comments surrounded different communication with a nurse compared with a patient. These results demonstrate that students developed deeper understanding of pathophysiology through active learning and were able to expand their nursing career skills during the role-play. Learning using role-play to simulate the workforce has fostered active learning.

Toward a model for forming psychological safety climate in construction project management

The nature of construction projects and their delivery exposes participants to accidents and dangers. Safety climate serves as a frame of reference for employees to make sense of safety measures in the workplace and adapt their behaviors. Though safety climate research abounds, fewer efforts are made to investigate the formation of a safety climate. An effort to explore forming psychological safety climate, an operationalization of safety climate at the individual level, is an appropriate starting point. Taking the view that projects are social processes, this paper develops a conceptual framework of forming the psychological safety climate, and provides a preliminary validation. The model suggests that management can create the desired psychological safety climate by efforts from structural, perceptual, interactive, and cultural perspectives. Future empirical research can be built on the model to provide a more comprehensive and coherent picture of the determinants of safety climate.
