Modeling Concordance Correlation Coefficient for Longitudinal Study Data

Measures of agreement are used in a wide range of behavioral, biomedical, psychosocial, and health-care related research to assess reliability of diagnostic test, psychometric properties of instrument, fidelity of psychosocial intervention, and accuracy of proxy outcome. The concordance correlation coefficient (CCC) is a popular measure of agreement for continuous outcomes. In modern-day applications, data are often clustered, making inference difficult to perform using existing methods. In addition, as longitudinal study designs become increasingly popular, missing data have become a serious issue, and the lack of methods to systematically address this problem has hampered the progress of research in the aforementioned fields. In this paper, we develop a novel approach to tackle the complexities involved in addressing missing data and other related issues for performing CCC analysis within a longitudinal data setting. The approach is illustrated with both real and simulated data.     

视觉的伦理关涉和悖论

视觉的悖论是由"看"与"被看"、权力和权利、形式设计与意义关怀等相反相成的关涉组成的混合体."看"与"被看"既反映出一种主客体之间的张力关系,也逐渐表现出其权力变化的趋向.通过权力和权利作为视觉伦理关系的两极,可以清晰地看到隐藏在视觉背后的意识形态性.视觉的形式设计与意义关怀的失衡必然带来视觉互动过程中的伦理偏差,过度强调视觉的形式设计必然会影响到视觉本身的传达效果,消解视觉的意义关怀所在,也会误导人们的价值观念.在视觉的伦理关涉和悖论后面,我们更需要寻找到实质为人与自然、人与自身、人与人、人与社会之间关系的平衡.     

Chronic administration of troxerutin protects mouse brain against d-galactose-induced impairment of cholinergic system

Previous evidence showed that administration of d-galactose (d-gal) increased ROS production and resulted in impairment of cholinergic system. Troxerutin, a natural bioflavonoid, has been reported to have many benefits and medicinal properties. In this study, we evaluated the protective effect of troxerutin against d-gal-induced impairment of cholinergic system, and explored the potential mechanism of its action. Our results displayed that troxerutin administration significantly improved behavioral performance of d-gal-treated mice in step-through test and morris water maze task. One of the potential mechanisms of this action was decreased AGEs, ROS and protein carbonyl levels in the basal forebrain, hippocampus and front cortex of d-gal-treated mice. Furthermore, our results also showed that troxerutin significantly inhibited cholinesterase (AchE) activity, increased the expression of nicotinic acetylcholine receptor alpha 7 (nAchRα7) and enhanced interactions between nAchRα7 and either postsynaptic density protein 95 (PSD95) or N-methyl-d-aspartate receptors subunit 1 (NMDAR1) in the basal forebrain, hippocampus and front cortex of d-gal-treated mice, which could help restore impairment of brain function.     

Linking Emotion to the Conflict Face‐Negotiation Theory: A U.S.–China Investigation of the Mediating Effects of Anger,Compassion, and Guilt in Interpersonal Conflict

This study linked emotion to the theoretical assumptions of the face‐negotiation theory and probed the critical role of anger, compassion, and guilt in understanding the complex pathways of their relationships with self‐construal, face concerns, and conflict styles in U.S. and Chinese cultures. Results showed that anger was associated positively with independent self‐construal, self‐face concern, and the competing style, and compassion was associated positively with interdependent self‐construal, other‐face concern, and the integrating, compromising, and obliging styles. Guilt was related positively with interdependent self‐construal and the obliging style in the United States, and with interdependent self‐construal and the avoiding style in China. Overall, emotion mediated the effects of self‐construal and face concerns on conflict styles in both cultures, but cultural differences also emerged.     

我国农村地区婴幼儿的喂养问题与对策

喂养不当是导致婴幼儿生长发育不良及营养障碍性疾病的主要原因。婴幼儿的喂养问题在我国农村地区尤为突出,主要表现在喂养方式、添加辅食和喂养行为等方面。文章重点围绕上述3个方面展开分析、提出对策,以期为政府决策、儿童保健人员及喂养者提供参考。     

国内心理治疗和咨询专业人员及工作状况调查

本研究的主要目的是考察国内目前心理治疗和咨询的人员及专业工作方面的地区差异,并做出比较.调查包括全国29个省、市、自治区的1543名被试.按照行政区域分为华北、东北、华东、中南、西南和西北六个地区.本研究采用自编的调查表对心理治疗师/咨询师个人情况和专业工作情况进行了调查.结果发现各地区发展确实存在不均衡的状况,华北、华东地区的相关人员专业水平较高,专职工作比较完善;而西北地区则相对比较落后,体现在治疗师倍询师专职化、专业化程度较低等方面.     

儿童基本心理需要满足对上网行为和上网情感的影响：一项追踪研究

在自我决定理论的框架下,对467名3~5年级小学生进行为期12个月的追踪调查,以探讨儿童基本心理需要满足对其上网行为和上网情感发展的影响。结果发现：（1）3~5年级儿童的上网时间、上网积极情感和上网消极情感在一年间存在着显著减少的发展趋势;（2）基本心理需要满足能够预测上网积极情感的增加和上网消极情感的减少,对上网时间发展的预测不显著;（3）自主、胜任和关系这三个维度对儿童上网情感的发展都起着重要作用。     

记忆编码中目标与背景的情绪一致性对记忆提取的影响

摘 要 本研究将经典情绪启动范式和学习-再认范式相结合,探讨学习时启动与目标的情绪一致性对目标再认的影响。在记忆编码阶段,以情绪面孔图片为启动刺激、一般情绪图片为目标刺激,要求被试对目标图片的效价进行判断;在提取阶段向被试呈现一般情绪图片,要求被试判断是否在前一阶段见过。结果表明,编码阶段的加工背景对记忆提取产生了显著影响。一致启动促进了认知加工与记忆编码,提高了再认正确率。ERP结果也表明,在目标刺激呈现后300-500ms,编码时的情绪一致性对再认阶段消极目标诱发的ERP产生了显著影响。

自传记忆线索提取发展的实验研究

自传记忆是关于个人生活的记忆。发展心理学家以生命历程的视野来研究自传记忆的发生、发展、变化是自传记忆研究的重要组成部分。自传记忆的形成和发展可分为三个阶段 :即童年期遗忘、回忆高峰、自传记忆近因期。本实验采用 2 (提取方式 :顺时、自由回忆 )× 2 (性别 :男、女 )× 8(年龄 :8个年龄组 )混合设计 ,结果发现 :(1 )顺时提取与自由提取两种提取方式对自传记忆的提取存在年龄差异 ,不仅有提取速度的差异 ,也存在提取内容的差异。 (2 ) 8个年龄段两种提取条件下的平均提取速度具有一致的趋同性 ,呈U型曲线 ,存在自传记忆的回忆高峰。 (3)自传记忆的跨生命历程提取不存在性别差异 ,年龄、性别、提取方式间不存在交互作用。 (4) 8个年龄段自传记忆的提取速度、提取内容与个人各年龄的生活主题存在内在关联。 (5)从提取机制支持Conway关于生命历程自传记忆发展的三阶段假设
