论卢卡奇社会历史辩证法的总体性理论之困境

回顾西方马克思主义发展历程,可以看到,卢卡奇的总体性理论是以社会历史辩证法的反思方式,质疑和批判了庸俗“经济唯物主义”,从而引领了一大批蔑视第二国际教条主义传统的西方左派知识分子,走向反思的马克思主义。而卢卡奇的总体性理论通过社会历史分析方法出具了革命方案,其反思方式是社会历史辩证法的,其解决方式是社会历史分析方法的;前者是人本主义倾向的,后者是科学化的。因此,卢卡奇的总体性理论存在着根本的理论困境,即对问题的反思方式和解决方式之间的矛盾。这一困境也大体奠定了卢卡奇本人理论发展以及继后的整个西方马克思主义…     

试析明清之际天主教书籍传教兴起的原因

明清之际入华的天主教传教士处于一种对他们极为不利的文化、政治环境中,加之教会自身条件的不足,他们被迫通过著书立说来消除中国人加之于他们的蛮夷丑号、规避政府禁令、弥补人手之缺以及跨越语言障碍。与此同时,教会人士认识到书籍在中国社会中具有特殊的重要性,因时就势,把书籍作为了归化中国人的手段。此外,传教士的"西儒"身份也让他们走上了笔耕之路。     

王夫之“文明史观”探论

十七世纪的中国哲学家王夫之已经有了初步的现代文明史观。他的史学著作中出现的“文明”概念,已经具备了现代文明学的基本要素,即具有文化发展的进步意义、制度文明等内容,而且特别阐发了人类生存的自然环境与人类文明类型之间的密切关系。在王夫之的文明史观中,制度文明的观念十分清晰。他高度肯定中国传统社会郡县制自身所具有的文明意义,以及郡县制对于维护人类文明生活方式的积极意义。而郡县制的文明特质在于三大要素,即父子之亲、君臣之义、华夷之别。由于王夫之身处明清易代的特殊历史时期,他特别重视文野之分意义上的“华夷之别”,体现了王夫之文明史观鲜明的时代性特征。     

血管壁切应力的优与非优

在生理水平的血管壁切应力属于优性因子,能促进血管重建,抑制内皮细胞凋亡,调节内皮细胞分泌功能,使内皮细胞形态产生适应性变化;而显著升高或降低的血管壁切应力则属于非优因子,导致高血压恶性循环发生、促进动脉粥样硬化及动脉血栓形成。实现切应力非优向优转化的重要途径是降低高血压和选择性阻断切应力对基因表达的调节     

Analgesic effect of Facebook: Priming with online social networking may boost felt relatedness that buffers against physical pain

Social networking sites (SNSs) are extremely popular for providing users with a convenient platform for acquiring social connections and thereby feeling relatedness. Plenty of literature has shown that mental representations of social support can reduce the perception of physical pain. The current study tested whether thinking about SNS would interfere with users’ perceptions of experimentally induced pain. Ninety‐six undergraduate Facebook users were recruited to participate in a priming‐based experiment. They were randomly assigned to one of the three study conditions (SNS prime, neutral prime, or no prime) via rating the aesthetics of logos. The results showed that participants exposed to SNS primes reported less pain of immersion in hot water than did both control groups (neutral‐ and no‐prime). Felt relatedness mediated the link between SNS primes and diminished pain perceptions. This research provides the first demonstration that thinking about SNS can lower experienced physical pain among Facebook users. Online social networking may serve as an analgesic buffer against pain experience than previously thought. The SNS‐enabled analgesia has far reaching implications for pain relief applications and the enhancement of well‐being in human‐interaction techniques.     

Effects of product portfolios and recommendation timing in the efficiency of personalized recommendation

Personalized recommendation has important implications in raising online shopping efficiency and increasing product sales. There has been wide interest in finding ways to provide more efficient personalized recommendations. Most existing studies focus on how to improve the accuracy and efficiency of the recommendation algorithms or are more concerned on ways to reduce perceived risks and thus increase consumer satisfaction. Unlike these studies, our study begins from the decision‐making process of consumers, using consumers' two‐stage decision‐making system and preference inconsistency theory as a basis, to reveal the mechanisms involved in consumers' acceptance of recommendations. This paper analyzes the effect of personalized recommendations from two angles, recommendation timing and product portfolio, tries to point out differences in consumer preferences between similar products and related products, and verifies that consumers demand diversity in the recommended content. The study analyzes differences in the acceptance of personalized recommendations between practical products and hedonic products and discovers that recommendations of hedonic products are more effective than that of practical products. Based on the research earlier, the study provides suggestions on how to better plan and operate a personalized recommendation system. Copyright © 2016 John Wiley & Sons, Ltd.     

高压氧对小鼠学习记忆及脑细胞形态结构的影响

实验用两种行为模型（旷场行为模型和Ｙ－迷宫分辨学习模型）观察了幼龄小鼠在不同压力的高压氧处理后,对新异环境的探究行为和自发活动情况,以及学习记忆能力的变化;并用ＸＹ－生物医学电脑图像分析仪分析了与学习记忆相关的脑区（大脑皮层、海马）神经元密度,细胞核面积,胞核／胞浆比值的变化。结果表明：（１）与对照组相比,吸０.１ＭＰａ高压氧的幼鼠学习记忆能力明显提高,相关脑区的神经元密度、细胞核面积、胞核／浆比均显著增加。（２）吸０.２５ＭＰａ高压氧的幼鼠学习记忆能力与对照组相比无明显变化,但其在新异环境中的自发行为明显减少。提示：慢性吸入０.１ＭＰａ高压氧有利于促进幼鼠脑的生长发育,增强脑功能活动。     

Analog scale,magnitude estimation,and person trade‐off as measures of health utility: biases and their correction

Subjects judged the disutility of health conditions (e.g. blindness) using one of them (e.g. blindness+deafness) as a standard, using three elicitation methods: analog scale (AS, how bad is blindness compared to blindness+deafness?); magnitude estimation (ME, blindness+deafness is how many times as bad as blindness?); and person trade‐off (PTO, how many people cured of blindness is as good as 10 people cured of blindness+deafness?). ME disutilities of the less bad condition were smallest, and AS was highest. Interleaving PTO with ME made PTO more like ME. AS disutilities were inconsistent with direct judgments of differences between pairs of conditions. ME and PTO judgments were internally inconsistent: e.g. the disutility of one‐eye‐blindness relative to blindness+deafness was larger than predicted from comparison of each to blindness. Consistency training reduced inconsistency, increased agreement between AS and PTO, and transferred from one method to the other. The results support the use of consistency checks in utility elicitation. Copyright © 2001 John Wiley & Sons, Ltd.
