丘处机与全真道在燕京的发展

全真道何时传入燕京①,已无确切资料可考,但全真道著名人物至燕京活动,始于金世宗召见七真之一的王处一。大定二十七年(1187年),七真中最以神异著称的王处一奉诏赴京,世宗亲问以养生之道,并命居天长观②。次年二月,七真之一的丘处机也奉诏赴京③。王处一和丘处机先后被召至燕京     

大鼠作业成绩与脑内亮氨酸脑啡肽含量变化的相关性研究

本工作采用穿梭式电击回避反应法和脑啡肽的放射免疫测定法,分析比较了大鼠作业成绩与脑内壳氨酸脑啡肽(Leu-enkephalin,LEK)含量的关系,在本实验条件下,观察到作业成绩不良组纹状体内LEK含量显著高于成绩优良组和对照组,并由实验证明,它们之间的差异不是由于在实验中接受电击的次数或电击总量不同造成的。这一结果提示,内源性亮氨酸脑啡肽可能参与记忆获得的调制。     

杏仁复合体损毁对大鼠空间认知能力的影响

杏仁复合体损毁大鼠Ｍｏｒｒｉｓ迷宫作业学习成绩显著低于控制组,记忆成绩较显著低于控制组。其搜索目标时主要采用与控制组的图式策略相异的趋向式策略。策略差异提示：杏仁复合体参与大鼠空间认知的辅助加工。     

龚道长慷慨解囊资助后学

应韩国国际仙道交流振兴院的邀请,中国道教协会张继禹副会长等2人于10月7日至12日赴韩国参加了首届中韩仙道文化交流学术研讨会。同时参加研讨会的中国学者还有陕西省社科院的两位道教研究专家。这是继任法融会长于去年6月率团访问韩国后,又一次高规格的中韩道教文化交流活动。     

社会认识的悖论分析

本文论为社会认识是一种特殊的认识,其特殊性表现为它是一种自认识,或者说是“悖论式”的认识,本文提出“双重角色悖论”、“视交叉悖论”、“纽康悖论”和“价值关涉悖论”,就社会认识的悖论现象作哲学分析,试图揭示社会认识活动的特殊性和规律性。     

Are Decisions Made by Group Representatives More Risk Averse? The Effect of Sense of Responsibility

We tested the hypothesis that a sense of responsibility drives group representatives' decisions to be more risk averse compared with decisions made by individuals. The hypothesis was supported when the monetary considerations (i.e., payoff inequality and the magnitude effect) were controlled for in the potential gain domain as well as in the potential loss domain. Evidence showed that this is because the group representatives were concerned about how they would view themselves (e.g., guilt and self‐blame) and also how they would be viewed by others (i.e., to avoid being blamed and looked down upon by others). This study provided new insights into understanding group representatives' decision making under risk. Copyright © 2017 John Wiley & Sons, Ltd.     

农村留守儿童焦虑情绪的异质性:基于潜在剖面分析

采用中学生心理健康诊断量表（MHT）对湖南省1292名留守儿童的焦虑情绪进行施测,并用潜在剖面分析方法探究留守儿童的焦虑情绪问题是否存在异质性,以及留守儿童相关的人口学因素对焦虑情绪异质性的作用机制。结果发现,留守儿童的焦虑情绪存在明显的异质性,可以分为三种潜在类别：“严重焦虑情绪型”、“中等程度焦虑情绪型”和“低焦虑情绪型”;留守男生、小学五年级、高中二年级、留守时间越长、留守初始年龄越小的留守儿童更容易焦虑情绪严重;无论是父亲外出、母亲外出还是双亲外出对留守儿童的焦虑情绪严重性的影响是一致的。由此,应根据留守儿童的性别、年级、留守时长和留守的初始年龄等情况特点,开展针对性的预防和干预措施,缓解留守儿童焦虑。     

学术界不应该吹捧风水术

1月27日,中国无神论学会和本刊编辑部邀请部分建筑、地质和传统文化研究的专家,召开了关于风水迷信问题的学术研讨会。研讨会上,有关专家对于风水迷信近年来的沉渣泛起表示了深深的忧虑。我们选编了他们的一些发言,并希望这个问题能够引起有关部门的高度重视。在这些忧虑之中,对某些所谓专家、学者行为的忧虑,是重要的内涵。因为正是某些专家、学者,把风水说成是建筑上的环境科学,是优秀的传统文化。这就给腐败的官员、行骗的风水先生提供了所谓理论根据。二十多年前特异功能兴起的时候,也是先有一帮所谓专家学者作出理论论证,一些官员表示支持。历史是何其相似,风水看来就要热到社会上层了。为了说明风水到底是什么,会后我们又组织有关学者,标点、翻译了古代有关风水迷信的代表性文献。这些文献告诉我们,如今被某些人鼓吹的“风水”,是一个有特定含义的概念。其特定含义就是讲葬地决定活人吉凶祸福。这里的“风水”,根本不是什么背风向阳,依山傍水之类的风水。某些人故意扩大风水的内容,只是为了给风水迷信披上科学的、合法的外衣。我们希望这里的文章和材料能够帮助某些人清醒一些。     

Impulsivity as a precedent factor for problematic Internet use: How can we be sure?

Previous research has suggested that problematic Internet use (PIU) is associated with impulse control disorder. Although researchers have suggested that impulsivity is a risk factor for PIU, the literature lacks longitudinal evidence on the relationship between impulsivity and PIU. We aimed to use a cross‐lagged analytic framework to identify temporal order effects and hypothesised that impulsivity was the precedent factor for PIU. In a panel sample of college students (N = 367), trait impulsivity and PIU were measured in the spring of freshman year and in their junior year. The measures included a self‐developed PIU Scale and the revised Impulsiveness Scale based on Barratt's concept. We found that “non‐planning impulsivity” was not associated with PIU. The “motor impulsivity” subfactor was thus adopted in the cross‐lagged model. The results suggest that motor impulsivity and PIU were stable across time. Motor impulsivity at Time 1 positively predicted PIU at Time 2, but PIU at Time 1 did not predict motor impulsivity at Time 2. A further investigation using gender as a moderator found a gender difference in the temporal relationship. Because motor impulsivity is a risk factor for PIU, potential prevention strategies based on this result are suggested.     

Dendrite growth velocity in the undercooled melt of glass forming Ni50Zr50 compound

Glass-forming Ni₅₀Zr₅₀ intermetallic compound is containerless undercooled and solidified using electrostatic levitation. Large undercoolings up to ?T = 300 K are achieved. The dendrite growth velocity of the congruently melting alloy is measured as a function of undercooling using a high-speed camera technique. The experimental data is analysed within a sharp interface theory. It is found that the driving force of crystallisation is controlling the growth kinetics at ?T < 250 K but at larger undercoolings the growth kinetics is progressively controlled by atomic diffusion. This leads to a slowing down of the growth velocity. The maximum velocity and the temperature at which the maximum occurs (T_max) are inferred from the dendrite growth velocity – undercooling relation. The relation of the temperature T_max and the glass temperature fits into a general classification scheme for glass-forming systems. The kinetic and thermal undercooling terms are calculated within dendrite growth theory as a function of the total undercooling. At ?T > 126 K, the kinetic undercooling dominates and increases rapidly with the undercooling ?T. The maximum prefactor of the kinetic undercooling is plotted vs. the reciprocal temperature. Its temperature dependence is discussed.
