虚拟与虚拟实在

虚拟是这个时代的热门词,也是当下文化的关键词.在三亿多的网民中,很多人见面时的问候语从吃过没有变为魔兽了吗抑或摘菜了没有,网络虚拟生活已经成为国人乃至世人一种必不可少的生活方式.二十年前美国学者迈克海姆写过一本关于虚拟实在的书,大约十年前引入国内,引发了国内学者关于虚拟实在的研究和讨论.但由于当时国内的信息技术尚未普及,网民数量稀少,所以他的书和这场讨论未能引起社会轰动并深入持久下去.如今恰逢读网时代,我们重拾虚拟实在,重新探讨它的形而上以及与虚拟的区别与联系,因为它是我们在谈及当下文化时绝不能回避和忽略的问题.     

Spatial Conceptions in Chinese and Canadian Children

Four-, five-, and six-year-old Chinese and Canadian boys and girls were presented a series of 11 graphic models and were asked to draw them. Supporting Piaget's theory, the data indicated that drawing performance on the topological dimension was better than the performance on the Euclidean dimension, and that there were neither gender nor cultural differences in performance. The research offers strong support for a main effect of biological or maturational factors as the foundation for the developmental influences in the acquisition of spatial conceptions.     

Amorphization of TiNi induced by high-pressure torsion

Using high-resolution electron microscopy, we investigated the initial stages of high-pressure-torsion-induced crystalline-to-amorphous transformation of TiNi. It is found that the deformation-induced amorphization initiated from dislocation core regions in the interior of grains and from grain boundaries. It is believed that both the energy stored in the dislocations and the energy stored in the grain boundaries contribute significantly to driving the crystalline-to-amorphous transformation.     

Electron microscopy of grain boundaries: An application to RE-Fe-B (RE = Pr or Nd) magnetic materials

Abstract

To study the grain boundaries of the technologically important RE_13.75Fe_80.25B₆ (RE = Pr or Nd) permanent magnets, we developed a new method using small-angle dark-field imaging based on inner-potential differences at the grain boundaries, combined with high-resolution electron microscopy and nanoscale chemical analysis. In both the Pr- and Nd-based melt-quenched die-upset magnets we consistently observed a very thin Fe-rich amorphized intergranular phase at the boundaries, and this finding may have an impact on our understanding of the coercivity mechanism of these materials. Although the value of the method was demonstrated for transition metal-rare earth intermetallics, it may also be applied to grain-boundary studies in other materials.     

学习困难儿童的注意、行为特性及同伴关系的研究

本文对学习困难儿童的注意、行为特性及同伴关系进行了研究.516名四、五、六年级的、学参加了本研究,有效被试505人.研究结果表明,学习困难儿童与学习优秀、学习一般儿童相,其注意力更不集中,更容易分心;他们更多动,冲动性更强,行为问题更多;他们的同伴关系更糟糕,在同伴中的地位更低.     

分配注意与发音抑制对视觉工作记忆的影响

本研究通过两个实验考察了分配注意与发音抑制对视觉工作记忆再认能力的影响.结果表明,保持阶段的分配注意与编码阶段的分配注意相比,对视觉工作记忆成绩影响更大;双任务条件下,被试正确回忆言语刺激时,视觉作业的正确率高,而错误回忆言语刺激时,视觉作业的正确率会降低;发音抑制与视觉工作记忆成绩无关.     

贵州省道教协会成立

2007年11月21日,贵州省道教第一次代表会议在贵阳举行.贵州省人大常委会副主任杨序颐、政协副主席唐世礼出席会议并讲话.会议审议并通过了<贵州省道教协会章程>,选举产生了贵州省道教协会第一届理事会和领导班子,张崇新当选为省道教协会会长,徐达双、唐至宗、邓信德、令狐昌乾等4人当选为副会长.     

字形信息在藏——汉双语者汉字词识别中的作用

采用启动范式下的真假字词判断任务,在两种SOA(60ms、100ms)条件下,考察字形信息在藏-汉双语者汉字识别中的作用。结果表明:(1)字形信息促进了语音信息的激活,字形信息影响了汉字识别的相对时间进程。(2)在汉字识别过程中,藏-汉双语者亚词汇单元的语音信息没有得到激活。(3)对于藏-汉双语者来说,语音信息的激活早于字形信息的激活。研究结果对我国少数民族学生的汉语教学具有重要的参考价值。     

国外社会心理学领域中主观幸福感的研究进展

社会心理学领域扩展与深化了现代主观幸福感的研究。本文介绍了国外社会心理学领域中有关主观幸福感研究的5个方面的新进展：适应与主观幸福感、记忆与主观幸福感、消极因素与主观幸福感、友好关系与主观幸福感、文化与主观幸福感,勾画出了幸福感的完整风貌,增进了心理学对主观幸福感的理解。
