In situ transformation from P phase to μ phase in rhenium-containing single-crystal superalloy during thermal exposure

An in situ phase transformation from P to μ in a rhenium-containing superalloy during high-temperature exposure has been investigated by transmission electron microscopy. The orientation relationship between the phases is found as (1–12)_μ // (1?0?0)_P and [2?4?1]_μ // [0?1?1]_P. An atomic model of the μ/P interface was built to reveal a perfectly coherent interface with lattice misfits of only 0.421 and 1.098%. Considering the small lattice distortions and the similar elemental composition of the phases, it is concluded that the phase transformation from P to μ is favourable.     

积极心理学研究综述--心理学研究的一个新思潮

中国人的人格特点(II):善良

该研究的目的是探讨不同性别、年龄、职业和婚姻状况的被试在善良人格维度上的特点。1276名被试在中国人人格量表(QZPS)的善良维度上的分数存在不同程度的性别、年龄、职业和婚姻状况差异,其中尤以性别和年龄的影响最大,年龄和职业的交互作用明显,而且婚姻状况会明显影响个体1的重感情倾向。文中还讨论了善良人格维度差异的意义以及将来研究的方向。     

抑郁症早醒对事件相关电位的关系研究

本研究旨在探讨抑郁症睡眠障碍早醒与事件相关电位P300的关系。 通过对22例抑郁症早醒病人、20例抑郁症非早醒病人及20例健康自愿者进行事件相关电位P300和汉密尔顿抑郁量表检测,结果发现,早醒组与对照组比较P2、N2、P3潜伏期与反应时间明显延长(P＜0.05),P2、N2、P3波幅明显降低;非早醒组与对照组比较N2、P3潜伏期与反应时间明显延长(P＜0.05),N2、P3波幅明显降低;早醒组与非早醒组比较P2、N2、P3潜伏期与反应时间明显延长(P＜0.05),N2、P3波幅明显降低。早醒组HAMD评分明显高于非早醒组(P＜0.05)。研究表明抑郁症早醒与非早醒病人均存在认知功能的损害,损害程度早醒病人比非早醒病人更为严重。     

刍议医德迷失与重塑

在我国的医疗行政界、医务界、医学教育界以及临床医者中出现了医德迷失现象.社会发展模式,道德激励游戏化,败德激励机制的精细化,个人生存压力,专业知识垄断等原因共同导致医德迷失.医德境界的提升应从教育做起,完善政策引导机制、社会监督评价机制,做好医务人员的岗前培训,提倡医者的自我修养.     

网络成瘾对青少年的社会性发展影响研究

本研究旨在探讨网络成瘾青少年与非成瘾青少年社会性发展的差异。结果表明:(1)网络成瘾青少年与非成瘾青少年在社会交往方面,如社会退缩等方面没有显著性差异;(2)在生活事件、网络使用时间、主观幸福感、社会支持、攻击性、无序感、自我和谐等方面都存在显著性差异。     

刻板印象威胁对城市出生流动儿童认知表现的积极效应及机制

本研究通过两个子研究考察刻板印象威胁对城市出生流动儿童认知任务表现的影响及其机制。研究1考察刻板印象威对城市出生流动儿童认知任务表现的影响。研究2考察专注与自尊在刻板印象威胁影响认知任务表现中的作用。结果发现,刻板印象威胁正向预测认知任务表现,而自尊调节专注在其中的中介效应：刻板印象威胁通过提升专注促进低自尊儿童认知任务的表现;专注的中介作用在高自尊儿童中不显著。     

Category norms as a function of culture and age: comparisons of item responses to 105 categories by american and chinese adults

Understanding how aging influences cognition across different cultures has been hindered by a lack of standardized, cross-referenced verbal stimuli. This study introduces a database of such item-level stimuli for both younger and older adults, in China and the United States, and makes 3 distinct contributions. First, the authors specify which item categories generalize across age and/or cultural groups, rigorously quantifying differences among them. Second, they introduce novel, powerful methods to measure between-group differences in freely generated ranked data, the rank-ordered logit model and Hellinger Affinity. Finally, a broad archive of tested, cross-linguistic stimuli is now freely available to researchers: data, similarity measures, and all stimulus materials for 105 categories and 4 culture-by-age groups, comprising over 10,000 fully translated unique item responses.
