‘But Suppose Everyone Did the Same’1 — The Case of the Danish Utopian Micro‐Society of Christiania

abstract The paper considers what (if anything) can justify that a utopian community or a micro‐society makes an exception to the general rules of society for itself. The discussion evolves around the Danish case of Christiania. Three moral theories, to wit Kantian constructivism, rule‐consequentialism and act‐consequentialism, are applied to the case at hand. The aim is to test whether the exceptions in question are unjust or in other ways morally problematic. The two former theories appear to deny the justice of Christiania. The relevant exceptions are unacceptable according to those two moral perspectives. Act‐consequentialism, however, seems to endorse the case of Christiania, including the exceptions pertaining to it. While the latter theory is often thought to conflict with widely shared reflective moral convictions, in this case it might square with at least an important pragmatic layer of Danish public culture.     

Family Environments and Children's Executive Function: The Mediating Role of Children's Affective State and Stress

There is increasing evidence that inadequate family environments (family material environment and family psychosocial environment) are not only social problems but also factors contributing to adverse neurocognitive outcomes. In the present study, the authors investigated the relationship among family environments, children's naturalistic affective state, self-reported stress, and executive functions in a sample of 157 Chinese families. These findings revealed that in inadequate family material environments, reduced children's cognitive flexibility is associated with increased naturalistic negative affectivity and self-reported stress. In addition, naturalistic negative affectivity mediated the association between family expressiveness and children's cognitive flexibility. The authors used a structural equation model to examine the mediation model hypothesis, and the results confirmed the mediating roles of naturalistic negative affectivity and self-reported stress between family environments and the cognitive flexibility of Chinese children. These findings indicate the importance of reducing stress and negative emotional state for improving cognitive functions in children of low socioeconomic status.     

Investigating the face inversion effect in a deaf population using the Dimensions Tasks

Early experience can change the way people process faces. Early deafness provides deaf children with the opportunity to learn sign language, which is likely to alter their face processing strategy. The goal of the current study was to investigate whether early deafness, combined with the sign language experience, was able to change the face processing strategy using the Dimensions Task. In the Face Dimensions Task, configural and featural information were parametrically and independently manipulated in the eye and mouth region of the face. The manipulations for configural information involved changing the distance between the eyes or the distance between the mouth and the nose. The manipulations for featural information involved changing the size of the eyes or the size of the mouth. Similar manipulations were applied in the House Dimensions Task, with top and bottom windows treated as eyes and mouth. In the Face Dimensions Task, both the signing deaf and hearing participants showed a larger inversion effect in the mouth condition than the eye condition. However, as compared to hearing participants, deaf participants showed smaller inversion effect in the mouth condition, because their performance in the inverted mouth condition was not compromised by inversion to the same extent as the hearing participants. In the House Dimensions Task, this effect was not present, suggesting that it was face specific. This effect could be explained by the redistributed attentional resources from the centre to peripheral visual fields of deaf participants.     

Influence of bidirectional perspective on learning routes and spatial layout

The capacity to remain spatially oriented is an essential function in our day to day lives and it seems that the form in which we acquire the spatial information affects the way in which the spatial knowledge is represented in our memory. The goal of this research was to investigate whether the acquisition of spatial information through the learning of three routes within an immersive environment was improved or impaired when participants have access to the backward perspective in addition to the forward perspective. Results, both in reproduction and drawing tasks, showed a poorer performance of the bidirectional group maybe due to the extra-effort involved in updating the spatial information trial by trial. However it seems that the experience enhanced the performance of the bidirectional group in one respect, as they were able to reduce significantly the number of error directions in the last path.

生存加工的编码和提取双重优势效应:ERP证据

生存加工比控制条件有更好的记忆表现,产生稳定的记忆优势,这就是记忆生存优势.已有研究多采用行为学实验验证了此现象的存在,但没有确定该优势发生在记忆的何种阶段.本研究采用ERP技术和“间接学习-再认”实验范式,比较被试在生存情境、迁徙情境和愉悦判断中对词汇编码和提取过程的记忆加工,结果发现:在500-700ms时间段,生存情境的相继记忆效应显著大于迁徙情境和愉悦判断:在400-600ms时间段,生存情境的新旧效应显著大于迁徙情境和愉悦判断.表明生存加工具有编码和提取双重优势.     

Effect of strain rate on the compressive behaviour of a Zr56Al10.9Ni4.6Cu27.8Nb0.7 bulk metallic glass

We report the study of the effect of strain rate on the compressive behaviour of a Zr₅₆Al_10.9Ni_4.6Cu_27.8Nb_0.7 bulk metallic glass. The results indicated that both the strength and plasticity of the glass increase with increasing the strain rate up to 10^?5 s^?1, above which the strength and plasticity start to decrease. The enhanced mechanical properties under a strain rate of 10^?5 s^?1 are due to the emission/propagation rate of the shear bands being consistent with the strain rate.     

基于多层验证性因素分析的各种信度系数方法

近年来,心理学研究的复现性受到广泛关注,许多实证研究难以重复验证,信度较低。大量研究使用多层技术,但只报告整体信度,导致研究可重复危机。基于各种信度系数和验证性因素分析的理论,以二层模型为例,总结多层信度计算方法,通过文献综述检索应用情况,并用MPLUS进行实例演示,最后讨论单层信度估计存在的偏差及分层估计的好处。总之,对多层数据进行分层信度估计是很有必要的,可消除因测量工具缺乏信度而导致的研究不可重复。     

论卡西尔的符号形式哲学

卡西尔文化哲学的创立是对传统哲学展开的一次整体性的批判,是以文化哲学的方式解答康德的哲学问题,构建起来的一种新的哲学.这一哲学以符号功能为核心概念,把人的文化创造活动、意义的表达作为哲学的最高存在,在此基础上改造了近代理性主义哲学的思维方式和提问方式,实现了哲学从理性批判到文化批判的转向.与其他的文化哲学家相比,卡西尔文化哲学的根本特点是:理性主义+生命哲学和哲学人类学.
