The long arm of time pressure at work: Cognitive failure and commuting near-accidents

This study tests whether cognitive failures mediate effects of work-related time pressure and time control on commuting accidents and near-accidents. Participants were 83 employees (56% female) who each commuted between their regular place of residence and place of work using vehicles. The Workplace Cognitive Failure Scale (WCFS) asked for the frequency of failure in memory function, failure in attention regulation, and failure in action execution. Time pressure and time control at work were assessed by the Instrument for Stress Oriented Task Analysis (ISTA). Commuting accidents in the last 12 months were reported by 10% of participants, and half of the sample reported commuting near-accidents in the last 4 weeks. Cognitive failure significantly mediated the influence of time pressure at work on near-accidents even when age, gender, neuroticism, conscientiousness, commuting duration, commuting distance, and time pressure during commuting were controlled for. Time control was negatively related to cognitive failure and neuroticism, but no association with commuting accidents or near-accidents was found. Time pressure at work is likely to increase cognitive load. Time pressure might, therefore, increase cognitive failures during work and also during commuting. Hence, time pressure at work can decrease commuting safety. The result suggests a reduction of time pressure at work should improve commuting safety.     

心力衰竭的药物及非药物治疗

神经内分泌激活、心室重构是收缩性心力衰竭进展的关键机制,针对上述机制的生物学治疗包括血管紧张素转换酶抑制剂、β受体阻滞剂、盐皮质激素受体拮抗剂等可显著改善心力衰竭患者预后,利尿剂、洋地黄等常规药物治疗可改善心力衰竭症状、降低心力衰竭住院风险,为神经内分泌拮抗剂的应用奠定基础;近年来,从阻断心力衰竭发生机制方面研发了很多新药,但尚没有一种能对长期生存率有显著改善.器械治疗(植入型心脏复律除颤器、心室再同步和心室再同步心脏复律除颤器)可降低特定心力衰竭患者病死风险,预防猝死发生,显著改善预后;心室辅助装置及干细胞治疗则为心力衰竭治疗带来新的曙光.     

慢性心力衰竭的病因学演变

慢性心力衰竭(CHF)是一个发病率不断增加且具有高病死率的临床症候群.尽管几十年来,药物及器械治疗取得了较大的进展,预后有所改善,但病因学组成一直发生着变化.冠心痛及高血压病成为中老年人CHF的主要病因.贫血、肾功能不全、慢性阻塞性肺疾病及糖尿病常与CHF并存并加重其预后.CHF的各种指南不断为心力衰竭的诊治提供新的信息并使预后进一步改善.     

《孟子》对戴震《原善》的影响

《孟子》在义理和话语两方面深深影响到戴震的《原善》。戴震将《易传》的“继善成性”与孟子的性善论区别为两个问题,前者是泛论,后者专论人性。受孟子断言“天之生物使之一本”的鼓舞,戴震严厉批评宋儒所谓性分义理、气质两种的学说犯了“二本”的错误。《原善》关于心的论述,关于“仁义礼智圣”和“条理”话语的使用,都鲜明表现出《孟子》的启发和影响。     

The perils of intimacy: Closeness and distance in feeding and weaning

This paper is based on work in the baby clinic of a general practice, with examples from infant observation, and ideas from recent research. It is something of an interdisciplinary paper.     

Near-term fetal response to maternal spoken voice

Knowledge about prenatal learning has been largely predicated on the observation that newborns appear to recognize the maternal voice. Few studies have examined the process underlying this phenomenon; that is, whether and how the fetus responds to maternal voice in situ. Fetal heart rate and motor activity were recorded at 36 weeks gestation (n = 69) while pregnant women read aloud from a neutral passage. Compared to a baseline period, fetuses responded with a decrease in motor activity in the 10 s following onset of maternal speech and a trend level decelerative heart rate response, consistent with an orienting response. Subsequent analyses revealed that the fetal response was modified by both maternal and fetal factors. Fetuses of women who were previously awake and talking (n = 40) showed an orienting response to onset of maternal reading aloud, while fetuses of mothers who had previously been resting and silent (n = 29) responded with elevated heart rate and increased movement. The magnitude of the fetal response was further dependent on baseline fetal heart rate variability such that largest response was demonstrated by fetuses with low variability of mothers who were previously resting and silent. Results indicate that fetal responsivity is affected by both maternal and fetal state and have implications for understanding fetal learning of the maternal voice under naturalistic conditions.     

Health,Healing and Wholeness in Frail Elderly People

ABSTRACT

This article explores the relationship between health, healing and wholeness in a group of twenty frail older residents of nursing homes, using in-depth interviews. While the participants in this study were all frail and lived with a number of disabilities, they demonstrated signs of transcendence in their responses to their disabilities. While independent living older adults in a previous study had all expressed fears of future vulnerability, only 45% of these nursing home residents said they had fears. Failure to thrive is discussed as one area of concern for frail older people, noting that this may stem from a lack of nourishment of the soul. Pastoral care is described as a multidisciplinary intervention for these residents, forming part of their wholistic care.     

Heart failure patients’ desires for spiritual care,perceived constraints,and unmet spiritual needs: relations with well-being and health-related quality of life

Little information is available about HF patients’ desires regarding having their healthcare providers address their spiritual concerns, feeling constrained in doing so, and the extent to which their spiritual needs go unmet. Nearly half of our sample reported high levels of unmet spiritual needs and reported moderately strong desires to have their doctor or other healthcare professional attend to their spiritual needs, and moderately strong feelings of constraint in doing so. Spiritual constraint and unmet spiritual needs were associated with poorer spiritual, psychological and physical well-being, but these effects varied, depending on patients’ desire to discuss spiritual needs. These findings have important implications for clinical management of HF patients.     

社会距离对成败行为性别归因偏差的影响

在陌生人和熟人两种社会距离下,让被试对同、异性成败行为进行归因,考查性别归因偏差现象(对异性美化、对同性贬损的归因)在社会距离上的变化。结果发现:(1)对于成功行为:被试对陌生异性做出的美化归因(能力-运气)显著高于陌生同性,出现性别归因偏差;被试对同、异性好友做出的美化归因差异不显著。(2)对于失败行为:被试对陌生同、异性做出的美化归因(运气-能力)差异不显著;被试对异性好友做出的美化归因显著高于同性,出现性别归因偏差。结论:性别归因偏差,在远社会距离他人表现成功时出现,表现失败时消失;在近社会距离他人表现成功时消失,表现失败时出现。结合相关研究和进化理论对结果进行了讨论。     

Adverse childhood experiences and autonomic regulation in response to acute stress: the role of the sympathetic and parasympathetic nervous systems

Background and objectives: After a previous report demonstrated blunted heart rate (HR) reactivity in association with adverse childhood experiences (ACEs) [Voellmin, A., Winzeler, K., Hug, E., Wilhelm, F. H., Schaefer, V., Gaab, J.,?…?Bader, K. (2015). Blunted endocrine and cardiovascular reactivity in young healthy women reporting a history of childhood adversity. Psychoneuroendocrinology, 51, 58–67. doi:10.1016/j.psyneuen.2014.09.008], the present analysis aimed at clarifying the role of the sympathetic and parasympathetic branches of the autonomic nervous system in this relationship.

Design and Methods: One hundred eighteen healthy young women provided data on ACEs and underwent psychosocial stress testing. Systolic blood pressure (SBP) and respiratory sinus arrhythmia (RSA, quantified by high-frequency HR variability) were assessed as measures of sympathetic and parasympathetic cardiovascular activity, respectively. A mediation model was calculated to test the indirect effects of ACEs on HR via SBP and RSA.

Results: The effect of ACEs on HR reactivity was mediated by SBP reactivity but not by RSA reactivity. ACEs were associated with reduced SBP at rest.

Conclusions: ACEs were associated with down-regulation in a measure of sympathetic but no alteration in a measure of parasympathetic cardiovascular stress reactivity in adulthood. Future research will need to clarify whether this indicates risk or resilience.
