Women's experience of brain injury: An interpretative phenomenological analysis

Acquired traumatic brain injury (TBI) can leave the survivor with a complex range of psychological sequalae. This study aims to investigate the experience from the perspective of women with acquired TBI. Using a qualitative research method, six women with a TBI were interviewed about their experience, and the interviews were transcribed verbatim and analysed according to Interpretative Phenomenological Analysis (IPA). The major themes that emerged were: awareness of change; the emotional reaction; struggling to make sense; adaptation and acceptance. This article describes the process of adaptation, and the implications for rehabilitation are discussed. It is suggested that an intervention based on these themes might be an effective tool in rehabilitation.     

Executive function outcomes of children with traumatic brain injury sustained before three years

Traumatic brain injury (TBI) is a common cause of disability in childhood. While the outcomes of TBI sustained in school years has been heavily researched, very little is known about the impact of TBI in infants and young children. The aim of this study was to investigate the impact of TBI on executive function (EF) in children who sustained a TBI before 3 years of age. A group of 55 children, 19 with a mild TBI, 16 children with a moderate-severe TBI, and 20 uninjured comparison children participated. The EF of children aged 3 to 6 years were compared using child-based measures of attentional control and information processing. Parents completed questionnaires rating their child's EF. Severity groups differed on the child-based EF measure of attentional control with children with TBI performing below the control group. There were no significant group differences for information processing or parent-rated EF. It appears that children who sustain a TBI before the age of 3 years display impairments in some areas of attentional control 3–4 years postinjury. The findings fit with the existing EF literature for older children.     

Partitioning and segregation of trace element Sn in a low-alloy steel

The partitioning of the trace element Sn into Cu-rich precipitates in a low-alloy pressure-vessel steel has been characterized using the three-dimensional atom probe (3DAP) technique. This investigation has revealed for the first time that the trace element Sn, present at only 0.007?at.% in the steel, partitions strongly to both small spherical precipitates (<4?nm in diameter) and to large non-spherical precipitates (largest dimension 10–50?nm) during thermal ageing. Sn was also seen to segregate strongly to the precipitate/matrix interface of a large Cu precipitate and particularly in the region where a dislocation appears to intersect the precipitate. The strong attraction of large solute atoms to special sites probably drives the interfacial segregation of Sn. This is consistent with the observation of stronger segregation of Sn to the interface of large precipitates than to the coherent interface of smaller precipitates.     

Electrical conductivity of Nd and Ce co-doped Gd2Zr2O7 ceramics

In this study, (Gd_{1? x} Nd _x )₂(Zr_{1? x} Ce _x )₂O₇ (0 ≤ x ≤ 0.5) ceramics have been prepared by pressureless sintering at 1973 K to investigate the influence of Nd and Ce co-doping on their electrical conductivity. The electrical conductivity of the ceramics was investigated by impedance spectroscopy measurements from 723 to 1173 K over the frequency range of 20 Hz to 2 MHz in air. The measured values obey the Arrhenius relation. For each composition, the grain conductivity gradually increases with increasing temperature from 723 to 1173 K. At a given temperature, it gradually decreases with increasing neodymium and cerium contents from x = 0 to 0.3; thereafter, the grain conductivity exhibits a slight increase with further increasing neodymium and cerium contents up to x = 0.5.     

Electropulsing-induced strengthening of steel at high temperature

Electropulsing usually promotes a metastable phase to evolve towards its equilibrium state. This work reports an alternative case, where electropulsing promotes the decomposition of the stable δ-phase in duplex stainless steel at high temperature. This decomposition enables both the γ-phase and the σ-phase in the steel to survive and hence to strengthen it at high temperature. The hardness of the quenched sample with electropulsing treatment is 49.4% higher than that without electropulsing treatment. A fundamental understanding of the observation is developed.     

The Illness/Injury Sensitivity Index: Validation of a German Version of the ISI-R

Three fundamental fears—anxiety sensitivity, fear of negative evaluation, and illness/injury sensitivity—are considered integral components of anxiety-related psychopathology and also bear connections with chronic pain. Scales measuring the first two fears, the Anxiety Sensitivity Index and the Fear of Negative Evaluation Scale, have been translated into German; however, the nine-item Illness/Injury Sensitivity Index-Revised (ISI-R) that measures fears of injury and illness has not been available in German language yet. The aim of this study therefore was a translation of the ISI-R into German language and an initial validation of the translated scale in two different samples. The German ISI-R was translated by both professionals and laypersons, and a final version was decided on by consensus. In Study 1, participants included 96 undergraduate students (85% women) who completed the German version of the ISI as part of a larger study. An exploratory factor analysis with oblique rotation was conducted and suggested a two-factor-solution with one factor representing fears of illness and the other fears of injury. This factor structure was confirmed via a confirmatory factor analysis (CFA) in Study 2. Participants included 117 community members (79% women). Convergent validity was supported using a visual analogue scale for fear of illness in both samples and the German translation of the Whiteley Index in Study. Overall, the results supported the German translation of the ISI-R. Comprehensive results, limitations, and directions for future research are discussed.     

心理负荷的评估:基于神经人因学的视角

心理负荷的评估正经历着从传统工效学向神经人因学的变革.EEG、ERPs、fMRI、fNIRS和TCD等神经科学研究技术为这场变革提供了有力的工具.研究发现:在单任务情境下,随着操作者心理负荷的增加,脑电α波活动减弱,θ波活动增强,并且前额皮层血流、左侧额下回血液氧合血红蛋白浓度变化均增加,大脑动脉血流速度也增快;在双任务情境下,随着操作者主任务心理负荷的增加,次任务的N1、新异P3和P3b等ERPs成分波幅降低.依据这些研究成果,学者们利用人工神经网络、支持向量机等模式分类算法实现了对心理负荷的实时在线评估.但是,各种研究技术在敏感性、诊断力、主任务干扰、实施需求、可接受性和信度等方面各有优势与不足.在未来研究中,要注意促进相关技术的融合、提高其可接受性,并充分利用模式识别算法提高其诊断力和敏感性.     

Sport,moral interpretivism,and football's voluntary suspension of play norm

In recent years it has become increasingly the norm in football1 1. For North American readers, football here equals soccer. to kick the ball out of play when a player is, or appears to be, inadvertently injured. Kicking the ball out of play in football represents a particular instantiation of a generally understood fair play norm, the voluntary suspension of play (VSP). In the philosophical literature, support for the VSP norm is provided by John Russell (2007 Russell, J. S. 2007. “Broad internalism and the moral foundations of sport”. In Ethics in Sport, 2nd edn, Edited by: Morgan, W. J. Champaign, IL: Human Kinetics.  [Google Scholar]) who claims that his interpretivist account of sport is helpful for evaluating complex moral issues in sport in general and issues related to injury in football in particular. This paper examines whether Russell's interpretivist-backed account of autonomy can adequately inform football players as to the nuanced and ambiguous moral considerations that arise in relation to the VSP norm. The paper goes on to identify the highly complex dynamic circumstances football players need to consider in order to better discharge their moral responsibilities when faced with inadvertent injuries.     

Personality Disorders and Spinal Cord Injury: A Pilot Study

A substantial body of research has found that spinal cord injury (SCI) patients have relatively high degrees of energy, impulsivity, and risk-taking (W. Fordyce, 1964; G. P. Taylor, 1970; B. Woodbury, 1978). The present study endeavors to extend our knowledge to the personality disorder (PD) domain. Forty SCI participants and 40 matched controls were given a semistructured diagnostic interview and a self-report personality disorder instrument. Findings indicated that 27.5% of SCI patients, and a similar number of controls, have PDs. Unexpectedly, impulsive/externalizing disorders (histrionic, narcissistic, antisocial, and borderline) were not unusually high in SCI patients, and were not higher than controls. Avoidant and depressive disorders were unexpectedly high.     

Crisis Support and Coping as Mediators of Well-Being in Persons with Spinal Cord Lesion

This study aims to investigate whether crisis support and coping mediate symptoms of posttraumatic stress disorder (PTSD) in individuals with spinal cord lesions (SCL). PTSD, crisis support, and coping were assessed an average of 83 days after the injury (T1), at discharge from the rehabilitation center (T2), and an average of 121 days following discharge (T3). Sixty-nine newly injured paraplegics and tetraplegics completed the questionnaire at T1, 40 (58%) at T2, and 38 (55%) at T3. Individuals with PTSD experienced significantly lower levels of social support, and used more emotional coping than did those without PTSD. On the basis of logistic regression analyses, emotional coping and the interaction between negative response and emotional coping predicted PTSD. Emotional coping is a strong predictor of PTSD in persons with new SCL.
