Effects of self evaluation on late ERP components

High-density event-related potentials (ERPs) were measured when participants were required to evaluate oneself, significant others (father and mother) and the most familiar public figures (Lei Feng and Jiang Qing) based on trait adjectives. There were three referential conditions and a non-referential control condition including self-evaluation (SE), significant other-evaluation (SOE), general other-evaluation (GOE), and semantic positivity-evaluation (SPE). The behavioral data showed that RTs to GOE condition were longer than the other three conditions. Scalp ERP analysis revealed that (1) SPE condition elicited a more negative N2 than SE condition, which was associated with inhibition of responses; (2) SE condition elicited a more positive P300 than SPE condition, which was an index of attention to self-relevant stimuli; (3) there was no difference on the amplitude and latency of P300 between SE and SOE conditions, which reflected that the concept of “self” included intimate others (e.g., father and mother) in Chinese culture.

小麦群体连续选择效应的综合分析

本试验对由信谷核不育基因构成的异效群体内４个性状进行连续两轮歧化选择，并将所得数据进行群体综合分析。结果表明：整个群体的平均表现和变异程度未发明显变化；但群体分布状况有一定改变，尤其是每穗粒数的分布数化较为明显；株高和千粒重的有效因子数估计基本符合小麦遗传实际表现，每穗粒数的有效有效因子数估计略低，说明此性状遗传背景较为简单。     

PbI_2－PbBr_2－KCl系统玻璃的形成及其析晶行为

ＰｂＩ_２可以单独形成玻璃。ＰｂＩ_２－ＰｂＢｒ_２－ＫＣｌ三元系统玻璃具有良好的玻璃形成能力。通过恰当的热处理，不仅可获得透红外性能与原始玻璃一致的微晶玻璃，同时还可克服自发析晶倾向和大幅度地提高玻璃的显微硬度。以此三元系统为基础，有望开发出一类具有实用前景的透红外玻璃材料。

人的全面发展观与学生党支部建设

“人的全面发展”观是马克思主义人学理论中的一个基本观点。全面发展的人是社会现代化的构成和目标，促进人的全面发展是社会主义现代化事业的目标和任务。高校学生党支部要按照人的全面发展的观点，调整党支部的工作思路，改进党支部的内部管理，形成充满活力的运行机制，使学生党支部真正成为高校学生中党的工作的主阵地。     

Electrochemical studies of glutathione monolayer assembled on a polycrystalline gold electrode

The glutathione (GSH) monolayer and complex monolayer of GSH-metallic ion on polycrystalline gold electrode were studied by using K₃Fe(CN)₆ as the redox probe. As for the GSH monolayer, it was found that the metallic ions could open the ion-gate in the monolayer dramatically in the order La³⁺> Pb²⁺>>Ba²⁺>Ca²⁺ whereas Zn²⁺ ion closed the ion-gate. The complexes of GSH-metallic ions were capable of self-assembling the different kind of monolayer. All the differences were related to the structural configuration of the anchored GSH molecule, which changed with different metallic ions or pH. Biography:Fang Cheng (1971-) male, Ph.
