The present study examined the processes by which children acquire pro‐environmental behaviours in different cultures. Our focus was on parental influence. Several studies have been conducted on adults' environmental behaviours; however, we know little about how children's environmental attitudes and behaviours are formed. We conducted a questionnaire survey with elementary school children and one of their parents in Germany and Japan. Two hundred and twenty‐one pairs participated in Germany and 365 in Japan. The results of structural equation modelling showed that parents' behaviours affected children's environmental behaviours directly and also via the subjective norm (the children's experienced expectations of their parents). A comparison of the two countries revealed that hypothesized cultural differences between the impact of personal norms and subjective norms were clearer for adults. The results also showed that the effects of subjective norms were stronger for children, indicating that children are more likely to be influenced by expectations of others. The results of the study suggest that for promoting children's environmental behaviours, showing the behaviours in daily life would be most effective.  相似文献

Coordination in health care action teams is an important factor in clinical performance and patient safety. Implementing a high-fidelity in situ simulation study, we investigated the performance-relevant effects of task distribution, provide information without request (PIWR) and closed-loop communication (CLC) in 68 medical emergency teams (METs) composed of fully qualified clinicians. We differentiated between two task types: algorithm-driven and knowledge-driven tasks. We assigned two different emergency tasks to each task type. We proposed not only a direct relationship between the three coordination behaviours and clinical performance, but also a moderating role for the type of task. Only CLC was related to performance and also moderated by task type. There was no relationship between the coordination behaviours task distribution and PIWR and performance. We discuss the differential effects of the three coordination behaviours on performance and emphasize the importance of the task in team research. In particular, we highlight theoretical and practical implications.  相似文献

For a little more than a decade, professional organizations and healthcare institutions have attempted to develop guidelines and policies to deal with seemingly intractable conflicts that arise between clinicians and patients (or their proxies) over appropriate use of aggressive life-sustaining therapies in the face of low expectations of medical benefit. This article suggests that, although such efforts at conflict resolution are commendable on many levels, inadequate attention has been given to their potential negative effects upon particular groups of patients/proxies. Based on the well-documented tendency among many African Americans to prefer more aggressive end-of-life medical interventions, it is proposed that the use of institutional policy to break decision making impasse in cases for which aggressive treatment is deemed "medically inappropriate" will fall disproportionately on that group. Finally, it is suggested that the development and application of institutional conflict-resolution policies should be evaluated in the context of historical and current experiences of marginalization and disempowerment, lest such policies exacerbate that experience.  相似文献

This study examined the role of perceived health in predicting theoretically-relevant aspects of smoking behavior among 161 young adult regular smokers (67 females; mean age = 21.9 years (SD = 7.2), cigarettes per day (M) = 12.2 (SD = 5.7)) recruited from the general community. Consistent with prediction, results indicated that relative to anxiety sensitivity, gender, number of cigarettes smoked per day and nicotine dependence, perceived physical health uniquely and significantly predicted expectancies for negative affect reduction and expectancies that smoking would lead to negative personal consequences. Additionally, perceived health incrementally predicted motivation to smoke to reduce negative affect. In contrast to expectation, perceived health was unrelated to motivation to quit smoking. Results are discussed in relation to the role of perceived health as a cognitive vulnerability factor for specific types of smoking patterns.  相似文献

In this study the detection of feigned memory impairments was investigated using a forced-choice task with Chinese words as stimuli. Task difficulty on accuracy and response time and the faking strategies employed were examined for 85 participants, 42 men and 43 women, who were administered the experimental task. Following a simulation design, all participants performed under control and faking conditions. Their accuracy of performance and response times were measured. Analysis indicated significant differences on both outcome measures for the two conditions. Further, a significant difference in accuracy, but not in response time, among levels of task difficulty was observed. For classification accuracy, using the cut-off score criterion seemed more effective than using the below-chance criterion or response time. Implications for relying on chance criterion to identify deception are discussed.  相似文献

The authors examined the temporal relation among posttraumatic stress disorder symptom clusters, using data derived from a longitudinal study of survivors of orofacial injury (N = 264). They conducted cross-lagged panel analyses, with self-reported symptom data collected at 1, 6, and 12 months postinjury. Results demonstrate that hyperarousal was a potent predictor of subsequent symptoms of reexperiencing and avoidance as well as hyperarousal. By contrast, neither reexperiencing nor avoidance was significantly related to other symptom clusters other than themselves over time. These findings underscore the distinctive nature of hyperarousal in the manifestation of posttraumatic psychological distress over time. Implications for theory, clinical intervention, and future research are discussed.  相似文献

The medical humanities are often implemented in the undergraduate medicine curriculum through injection of discrete option courses as compensation for an overdose of science. The medical humanities may be reformulated as process and perspective, rather than content, where the curriculum is viewed as an aesthetic text and learning as aesthetic and ethical identity formation. This article suggests that a "humanities" perspective may be inherent to the life sciences required for study of medicine. The medical humanities emerge as a revelation of value inherent to an aesthetic medicine taught and learned imaginatively.  相似文献
