组织文化对ERP系统消化吸收阶段知识共享作用机理的实证研究

在竞争价值模型和知识共享理论的基础上,建立组织文化对ERP知识共享的影响模型,分别探索了企业内部的发展文化、组文化、等级文化和理性文化对ERP系统消化吸收阶段显性和隐性知识共享的作用机理。基于来自115家企业的343份调查问卷,采用结构方程模型对组织文化的作用机理进行了实证分析。分析结果表明:强调信任与参与的组文化有利于ERP隐性知识的共享;而强调内部稳定的等级文化和强调生产率的理性文化既有利于ERP显性知识的共享,又有利于ERP隐性知识的共享。

Features of intervertebral disc degeneration in rat’s aging process

Objective: The age-related change is important part of degenerative disc disease. However, no appropriate animal model or objective evaluation index is available. This study aimed to investigate the features of intervertebral disc degeneration in aging process of rats. Methods: 22-month-old Sprague-Dawley (SD) rats were used as spontaneously occurring intervertebral disc degeneration models and 6-month-old rats as young controls. Expression of collagen types II and X was measured by immunohistochemistry. Degenerations of intervertebral discs were scored according to Miyamoto’s method. Numbers and areas of afferent vascular buds were measured. The thicknesses of non-calcified and calcified layers were measured and statistically analyzed. Results: There were less collagen type II expression and more collagen type X expression in the calcified layer of the cartilage endplates and nucleus pulposus in the rats of the aged group than in the young control. There were fewer and smaller afferent vascular buds in the rats of the aged group than in the young control group. The ratio of the non-calcified to the calcified layers in the rats of the aged group significantly decreased, compared with that of the young control group (P<0.01). Conclusion: Rats can spontaneously establish intervertebral disc age-related degeneration. The expression of collagen types II and X, numbers and areas of afferent vascular buds, the ratio of the non-calcified to the calcified layers, and water and glycosaminoglycan contents in the nucleus pulposus are sensitive indexes of intervertebral disc degeneration.

情感表达的跨文化多模态感知研究

视频和音频2个模态的信息在交际过程中起着至关重要的作用,该文研究关注的问题是情感表达中不同文化背景的听者对情感的感知(解码)与这2个模态(面部表情和情感声音)的关系。发音人为中国人,录制她的5个语句的7种情感(6种基本情感+中性情感)的音频和面部表情,制作3类刺激:只有音频信息(A-only)、只有面部视频信息(V-only)以及视频和音频同步信息(AV-Congruent)。听辨人为10名不会日语的中国人和10名不会汉语的日本人。对听辨结果分析发现,面部视频信息的加入有益于情感的感知,视频和音频信息在跨文化的情感解码中起着不同的作用,与情感的唤醒度有密切的关系,相关距离空间分布模式说明听辨结果具有稳定性,跨文化的情感感知存在普遍的心理基础。     

论邓小平对马克思社会进步评价标准的继承和发展

马克思认为，生产力的发展与人的发展是社会进步的评价尺度。这两种尺度同时也是我国社会主义现代化建设的价值取向。社会主义现代化建设，既是生产力发展的过程，也是人的全面发展的过程。邓小平继承和发展了这一思想，把发展生产力作为社会主义的根本任务，把人的全面发展作为社会主义建设的最终目的，并通过改革开放这一根本途径来促进生产力发展和人的发展。
