工程决策中的伦理问题及其对策

工程决策中的伦理问题是工程伦理学中最重要的问题.尽管工程决策所要考虑的伦理因素常常已经以不同的形式作为工程师的职业道德的一部分,在工程师协会章程或伦理规范里得到表达,但是仅此对于建造好的工程无济于事.如果没有合理的决策机制和决策程序,单靠工程师个人的力量,这些表达出来的要求是难以贯彻的.所以,什么人做决策和按什么程序决策就十分重要.建立"工程伦理委员会",按照民主程序,经过充分讨论协商,是正确处理工程决策中的伦理问题,最终作出最佳决策的切实可行的途径.     

Rapid contact call-driven induction of NR2A and NR2B NMDA subunit mRNAs in the auditory thalamus of the budgerigar (Melopsittacus undulatus)

In situ hybridization histochemistry was used to assess the effect of auditory stimulation with natural contact calls on expression of NR2A and NR2B NMDA subunit mRNAs in neurons of the thalamic auditory relay nucleus ovoidalis (Ov) of a vocal learning parrot species, the budgerigar (Melopsittacus undulatus). The results showed that both the core (Ov) and ventromedial shell subdivisions (Ovm) of ovoidalis contained neurons expressing NR2A and NR2B mRNA in no-stimulation control subjects and that the distributions of neurons expressing these subunit mRNAs were very similar in both the core and shell of Ov. Contact call stimulation (5, 30 and 180 min) resulted in substantial increases of 50-60% in the number of neurons expressing NR2A and NR2B mRNAs in both the core and shell. Staining intensity, as measured by the optical density of stained somata approximately doubled compared to controls for both NR2 subunits in the 5 and 30 min conditions, but declined from 30 to 180 min. In all conditions, the density, but not staining intensity, of neurons expressing NR2B exceeded NR2A expression. Furthermore, the density of neurons expressing both subunit mRNAs in call stimulation conditions was greater in the core than in the shell despite the fact that total neuronal density was approximately 20% higher in the shell. Previous experiments have shown that call stimulation is more effective at inducing expression of the immediate early gene zenk in the Ov shell than core; however the present results do not indicate that either NR2A or NR2B mRNA expression mediates this effect since neither subunit exhibits greater expression in Ovm. Ca(++) release is needed for immediate early gene expression, however and, notably, Ovm contains large numbers of neurons containing CGRP, a peptide which has been shown to increase cytosolic Ca(++) levels.     

句子阅读的内隐自尊研究

本研究尝试通过22名被试在阅读自我成败句子及他／她成败句子时的眼动数据来探讨内隐自尊,结果发现阅读主语人称为“我”的句子时．自我成功句子与自我失败句子的第二次注视时间及瞳孔大小存在差异,这提示内隐自尊存在,个体会无意识地对自我积极信息进行深度加工。     

组织认同的基础理论、测量及相关变量

组织认同是个体源于组织成员身份的一种自我构念,它与组织认定、组织承诺等概念存在显著差异。文章阐述了组织认同基础理论的三种主要观点,对比了差异论、资源论和信息论的研究视角和相互关系。文章着重说明了组织认同的测量工具,分析了组织层面和个人层面的前因变量,以及组织认同对离职意愿等结果变量的影响。文章最后指出今后有必要对扩展定义、影响因素和国家文化差异等方面进行探讨     

人类视空间工作记忆分离的证据与机制

视空间工作记忆系统是否可以分离及分离的内在机制是当前工作记忆研究中的一个热点问题,神经心理学、潜变量、双分离、发展以及脑机制的研究所提供的大量实验结果证明,人类的视空间工作记忆存在分离。一些研究进一步揭示,编码方式的不同和注意参与机制的差异可能是导致视空间工作记忆分离的两个主要原因。这篇文章对已往实验结果进行了论述、分析和评价,指出了以往研究尚未解决的问题以及未来研究应该关注的方向

Toward a Social Psychology of Culture and Globalization: Some Social Cognitive Consequences of Activating Two Cultures Simultaneously

Despite the increased attention given to cultural phenomena in social psychology, the field has neglected issues related to globalization's cultural impacts. Meanwhile, opinions in the debates over these issues are divided, polarized, and often motivated by political and ideological commitments. Globalization has brought symbols of diverse cultures together and provided ample opportunities for the simultaneous activation of two or more cultural representations. Using our research on the social cognitive consequences of activating two cultural representations simultaneously as an example, we argue for constructing a social psychology of globalization that offers nuanced understandings of people's psychological responses to globalization. Although simultaneous activation of cultural representations does not determine an individual's cultural identity, it enlarges the felt distinctions between different identity options and magnifies the effects of identity choice. Furthermore, in situations that emphasize appropriating intellectual resources from diverse cultures to foster creativity, simultaneous activation of cultural representations may facilitate creative performance.     

精神分裂症患者团体绘画艺术干预

探讨团体绘画艺术治疗对精神分裂症患者生理、心理和社会功能康复效果。86名精神分裂症住院患者被随机分配到干预组或对照组。干预组被试接受团体绘画艺术干预活动,对照组从事其他康复活动。结果发现,干预组被试阳性与阴性症状量表总分低于对照组被试,大体评定量表分数高于对照组被试,自我概念总分高于对照组被试,生活质量问卷的躯体功能、心理功能和社会功能维度高于对照组被试。团体绘画艺术干预可以缓解精神分裂症患者的精神症状,促进患者自我概念和生活质量的提升。
