Development and test of a model linking safety-specific transformational leadership and occupational safety

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.     

Relationship between heart rate variability and cognitive function during threat of shock

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.     

Perseverative Thinking and Health: Neurovisceral Concomitants

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.     

Resilience is associated with better recovery in Chinese people diagnosed with coronary heart disease

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.     

Wiederkehrende,primäre Kopfschmerzen im Jugendalter

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.

     

The Innate Bases of Fear

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.     

‘No entry’, an invitation to intrude,or both? Reflections on a group of anorexic patients

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.     

Philosophical Autobiography

An examination of the genre of philosophical autobiography sheds light on the role of personal judgment alongside objective rationality in philosophy. Building on Monk's conception of philosophical biography, philosophical autobiography can be seen as any autobiography that reveals some interplay between life and thought. It is argued that almost all autobiographies by philosophers are philosophical because the recounting of one's own life is almost invariably a form of extended speech act of self-revelation. When a philosopher is the autobiographer, this self-revelation illuminates the interplay between thought, life, and personality. Understanding how this works allows us to address three problems of biography raised by Honderich: how to give an account of something as large and complex as a human life; how a life-story is also a judgment; and how we can justify identifying one part of a causal circumstance as 'the cause'. There is also a new ethical problem raised about the autobiographer's right to make public details of a shared private life.     

Why computational models are better than verbal theories: the case of nonword repetition

Tests of nonword repetition (NWR) have often been used to examine children's phonological knowledge and word learning abilities. However, theories of NWR primarily explain performance either in terms of phonological working memory or long‐term knowledge, with little consideration of how these processes interact. One theoretical account that focuses specifically on the interaction between short‐term and long‐term memory is the chunking hypothesis. Chunking occurs because of repeated exposure to meaningful stimulus items, resulting in the items becoming grouped (or chunked); once chunked, the items can be represented in short‐term memory using one chunk rather than one chunk per item. We tested several predictions of the chunking hypothesis by presenting 5–6‐year‐old children with three tests of NWR that were either high, medium, or low in wordlikeness. The results did not show strong support for the chunking hypothesis, suggesting that chunking fails to fully explain children's NWR behavior. However, simulations using a computational implementation of chunking (namely CLASSIC, or Chunking Lexical And Sub‐lexical Sequences In Children) show that, when the linguistic input to 5–6‐year‐old children is estimated in a reasonable way, the children's data are matched across all three NWR tests. These results have three implications for the field: (a) a chunking account can explain key NWR phenomena in 5–6‐year‐old children; (b) tests of chunking accounts require a detailed specification both of the chunking mechanism itself and of the input on which the chunking mechanism operates; and (c) verbal theories emphasizing the role of long‐term knowledge (such as chunking) are not precise enough to make detailed predictions about experimental data, but computational implementations of the theories can bridge the gap.
