Development and test of a model linking safety-specific transformational leadership and occupational safety 总被引:13,自引:0,他引:13
The authors developed, tested, and replicated a model in which safety-specific transformational leadership predicted occupational injuries in 2 separate studies. Data from 174 restaurant workers (M age = 26.75 years, range = 15-64) were analyzed using structural equation modeling (LISREL 8; K. G. J?reskog & D. S?rbom, 1993) and provided strong support for a model whereby safety-specific transformational leadership predicted occupational injuries through the effects of perceived safety climate, safety consciousness, and safety-related events. Study 2 replicated and extended this model with data from 164 young workers from diverse jobs (M age = 19.54 years, range = 14-24). Safety-specific transformational leadership and role overload were related to occupational injuries through the effects of perceived safety climate, safety consciousness, and safety-related events. 相似文献

Abstract The aim of the present study was to investigate the relationship between resting heart rate variability (HRV) and cognitive functions during threat of shock. A Continuous Performance Task and a Working Memory Task were used to measure cognitive functions. Sixty-five male participants from the Royal Norwegian Navy participated. HRV was measured during baseline, test conditions and recovery. Participants were randomly assigned into non-threat and threat groups. Based on the median split of the high frequency (HF) spectral power, groups were divided into two additional groups. Overall, the high HRV participants showed superior performance on cognitive tasks independent of non-threat or threat conditions. During threat condition the low HRV group showed improved performance. Thus, individuals with high HRV were more stress tolerant and resilient in the face of environmental changes. The results from the study might have implications with regard to performance in operational settings, but also for other fields of psychological research such as individual differences, anxiety and coping. 相似文献

In the present paper we present the outlines of a model that may help to guide us in our understanding of the relationship between perseverative thinking and health. We will emphasize the relationship between perseverative thinking and vagal cardiac control and propose a group of underlying neural structures that serve to integrate these functions in the service of self-regulation and adaptability of the organism. We will attempt to place this network in the context of systems models which involve feedback and feedforward circuits with special attention to negative feedback mechanisms and inhibitory processes. From a systems perspective, inhibitory processes can be viewed as negative feedback circuits that allow for the interruption of ongoing behavior and the re-deployment of resources to other tasks. When these negative feedback mechanisms are compromised, positive feedback loops may develop as a result of dis-inhibition. From this perspective, the relative sympathetic activation seen in perseverative thinking may represent dis-inhibition due to faulty inhibitory mechanisms. 相似文献

This study investigated the impact of personal resilience (a composite measure of optimism, perceived control and self-esteem) on outcome measures in 67 Chinese coronary heart disease patients in response to an 8-week rehabilitation programme. The effect of personal resilience on posttraumatic growth attributed to the onset of heart disease was also examined. Results indicated that coronary heart disease patients high in personal resilience achieved better outcomes than those low in personal resilience, as indicated by higher physical and mental summary measures in SF-36, lower cholesterol levels and better performance on the 6?min walk test. Moreover, personal resilience was demonstrated to be a significant predictor of the level of posttraumatic growth although the rehabilitation programme exerted a weak mediating effect on the link between personal resilience and posttraumatic growth. Findings were discussed in relation to clinical implications of the construct of personal resilience and the intervention programme. 相似文献

Background
Recurrent pain, especially primary headache, is a serious health problem in adolescents. Music therapy in the treatment of children with migraine has already been evaluated. The aim of this pilot study was to adopt this treatment manual for adolescent patients with recurrent primary headache in preparation for the main randomized controlled trial.Patients and methods
In this pilot study two different modes of treatment (standard and compact treatment) were tested in an outpatient setting with 19 patients. Frequency and intensity of headache symptoms were evaluated using pain diaries for 8 weeks in a pre-post design.Results
The pilot study showed good feasibility of both treatment conditions in outpatient practice. Patients reported a reduction of pain frequency and intensity in both groups. The evaluation of the clinical relevance of these effects remains the objective for the main trial.Conclusions
The music therapeutic treatment plan for children with migraine is even feasible in the treatment of adolescents with recurrent, primary headache. Further evidence questioning the effectiveness of the treatment under controlled conditions is needed.497.
Changes in choices of preferred playmates by 3- and 4-year-old children were observed over the course of a school year. All of the children in this study participated in planned, fully mainstreamed, same-age preschool classes. Sociometric assessments were obtained from all children without disabilities in October, February, and May of the school year; peer nominations of three “best friends” were obtained at the beginning and end of the school year. The 3-year-old children showed a general decline in the ratings given to all of their peers over the course of the school year. Four-year-old children showed significant preferences for same-sex peers without disabilities as playmates. The implications of these findings for integrated programs are discussed. 相似文献

This study addressed the effects of children's understanding of social learning principles on divergent areas of behavior: two indices of self-control, grade scores, personality and conduct problems, immaturity, and subcultural delinquency. Using an orthogonal 2 × 2 (Understanding of Social Learning Principles × Age) multivariate analysis of variance on 44 children, we found no significant interaction or a knowledge of social learning principles main effect. 相似文献

This paper describes the twice‐weekly psychoanalytic psychotherapy of a young woman who had undergone major bowel surgery in her early 20s, with no clear medical indication for the surgery. Whilst the concept of ‘No Entry’ described by Williams ( 1997a , b ) aptly describes many features of more ‘typical’ anorexic patients, this paper describes a particular group of anorexic patients, referred by their physicians for multiple medical procedures; and proposes there is a group of anorexic patients, repeatedly referred for medical investigations, into whom particular types of entries occur. These are entries into the body ‘legitimized’ as medical, with a trajectory towards multiple procedures, examinations and surgical operations. Other entries (outside the medical setting) may occur in a state of altered consciousness, under the influence of alcohol or drugs, such that any wish for intrusion is disowned and denied. In both sets of events, intrusion is both invited, and consciously denied. The case example illuminates some of these features, and aspects of the countertransference are also described. Attention is drawn to relevant research focusing on surgical intrusion. Finally, there is an exploration as to how such patients may invite intrusions into the body through surgery and medical procedures. 相似文献
