资本主义研究在马克思社会形态理论中的地位

<正>社会形态理论是马克思主义的研究者最为重视的马克思历史理论之一,甚至被看作历史唯物主义的核心部分,但同时也是引起最多争议和质疑的部分。然而,无论是关于社会形态演进序列之"五形态"与"三形态"的争论,还是关于社会形态的依次演进是否具有历史必然性的争论,抑或关于     

青年情绪智力与主观幸福感的关系

以444名青年为研究对象,采用Schutte编制的《情绪智力量表》、艾森克人格问卷和Diener等人编制的《国际大学调查》为研究工具,调查青年各群体的主观幸福感水平,并对情绪智力和主观幸福感的关系进行了研究。结果发现,青年不同群体之间存在显著的主观幸福感差异,本科生群体的主观幸福感水平最高;在控制了人口学变量和人格变量之后,情绪智力能独立预测主观幸福感各维度的变异。     

Role of the NO/sGC/PKG signaling pathway of hippocampal CA1 in morphine-induced reward memory

Evidence suggests that the nitric oxide (NO)/soluble guanylyl cyclase (sGC)/cGMP dependent protein kinase (PKG) signaling pathway plays a key role in memory processing, but the actual participation of this signaling cascade in the hippocampal CA1 during morphine-induced reward memory remains unknown. In this study, we investigated the role of the NO/sGC/PKG signaling pathway in the CA1 on morphine-induced reward memory using a conditioned place preference (CPP) paradigm. We found that rats receiving an intraperitoneal (i.p.) injection of 4mg/kg morphine exhibited CPP, whereas rats treated with only 0.2mg/kg morphine failed to produce CPP. Intra-CA1 injection of the neuronal NO synthase (nNOS) inhibitor 7-NI, the sGC inhibitor ODQ or the PKG inhibitor Rp-8-Br-PET-cGMPS had no effect on the acquisition of CPP by 4mg/kg morphine. Intra-CA1 injection of 7-NI blocked the consolidation of CPP induced by 4mg/kg morphine, and this amnesic effect of 7-NI was mimicked by ODQ and Rp-8-Br-PET-cGMPS. Intra-CA1 injection of the NOS substrate L-arg or the sGC activator YC-1 with an ineffective dose of morphine (0.2mg/kg, i.p.) elicited CPP. This response induced by L-arg or YC-1 was reversed by pre-microinjection of Rp-8-Br-PET-cGMPS in the CA1. These results indicated that the activation of the NO/sGC/PKG signaling pathway in the CA1 is necessary for the consolidation of morphine-related reward memory.     

背景性质对7-10岁自闭症谱系障碍儿童面孔搜索与加工的作用

为了考察背景性质对ASD者搜索面孔的影响,设计两个眼动实验任务,要求14名7~10岁ASD儿童和20名同年龄正常儿童观看图片。实验一采用将面孔嵌入风景图片中引起语义不一致的刺激;实验二采用含有面孔的无意义背景乱序图片刺激。结果发现：（1）面孔与背景语义不一致并不能促进ASD儿童对面孔的搜索;（2）乱序背景对ASD儿童面孔搜索与加工没有产生干扰作用,但使正常儿童的搜索时间变长;（3）一旦觉察到面孔后,ASD儿童对面孔的注视时间少于正常儿童。表明正常儿童对面孔的搜索与加工受背景性质的影响,而ASD儿童不受背景性质的影响;一旦发现面孔,ASD儿童的注意维持较短,但面孔加工模式与正常儿童相似。

Shear band evolution during large plastic deformation of brittle and ductile metallic glasses

Four monolithic metallic glasses (MMGs) with different plasticities varying from brittle to ductile behavior under unconstrained loading were subjected to small punch testing. All specimens undergo large plastic deformation with multiple cobweb-like shear bands under these conditions. The process of shear band evolution was carefully controlled and investigated. Plasticity of MMGs is characterized by equivalent plastic strain ε* (product of shear band density and critical shear offset). Thus, this article provides an experimental basis for a better understanding of the shear band evolution during plastic deformation of MMGs.     

Surface effect on the screw dislocation mobility over the Peierls barrier

The effect of the image force on the Peierls stress (τ _p ) of a screw dislocation below a free surface is studied via a self-consistent semidiscrete variational Peierls–Nabarro model. The consequence of reduction in elastic energy and increase in stacking fault energy by the presence of the free surface is found to additively increase the Peierls stress (τ _p ). This model gives a physical interpretation of the same tend observed in a recent molecular dynamic study, while previous continuum analysis predicted the opposite.     

Stair-rod dislocations in perovskite films on LaAlO3 substrates

Two types of stair-rod dislocation formed at junctions of {111} stacking faults in SrTiO₃-SrRuO₃ two-layer films on LaAlO₃ substrates have been studied by high-resolution transmission electron microscopy. The first type, formed by the interaction of two stacking faults situated at the flat SrRuO₃-LaAlO₃ interface without any step, has a Burgers vector (a/3)<110>. The other type, formed by the interaction of two stacking faults, of which one starts from the SrRuO₃-LaAlO₃interface area involving an interface step, has a Burgers vector (a/3)<120>. The formation mechanism of the stair-rod dislocations and the effect of the step are discussed.     

A Model of Chinese Adolescents' Creative Personality

Since the 1950s, there has been a systemic development of research on creative personality. Three themes are apparent in this literature: individual differences of creative people, the construct of creative personality, and longitudinal studies about creative personality. However, little research has been conducted in any of these areas with Chinese samples, and the purpose of this study is to study the construct of Chinese adolescents' creative personality. Confirmatory factor analyses were conducted with data from 1,300 Chinese adolescents. The results provide evidence that adolescents' creative personality consists of three largely independent dimensions: Internal, External, and Self. The internal factor includes self-confidence, norm-doubt, internal motivation, and persistence; the external factor includes curiosity, risk-taking, openness and independence; the self factor pertains to self-acceptance.     

Right Hemispheric Dominance of Creative Insight: An Event-Related Potential Study

The purpose of this study was to investigate the hemispheric effect of creative insight. This study used high-density ERPs to record participants' brain activity while they performed an insight task. Results showed that both insight solutions and incomprehension solutions elicited a more negative ERP deflection (N320～550) than noninsight solutions in the time window of 320～550 msec. Scalp ERPs and topographical maps revealed that the insight N320～550 exhibited a relative RH dominance, whereas the incomprehension N320～550 exhibited a relative midline dominance. Dipole source analysis showed that the generator of N320～550 elicited by insight and incomprehension solutions was localized in the right middle frontal gyrus and the right parahippocampus gyrus, respectively. These distinct spatiotemporal patterns involved in insight processing and incomprehension processing suggest that the observed N320～550 might reflect the processing of set-shift and the formation of novel associations. Moreover, the spatiotemporal pattern of brain activation associated with insight solutions supported the idea that the right hemispheric dominance theory of creative thinking also applies to creative insight.
