近年来我国医药工业取得了突出成绩,但医药企业面临复杂的内外部环境,需尽快打破同质化严重、竞争力不足的格局,向创新驱动转型。创新管理的理论观点对于创新型医药企业有借鉴意义,分析了尚处于发展阶段的创新型医药企业在文化、组织和创新能力建设等方面的一些问题,参考创新理论的一些观点,认为创新型医药企业可在不断追求技术、产品创新的同时,思考对企业文化、组织管理、创新能力方面的变革,从而有效地推进创新战略实施。

第二次认知革命与社会建构论的产生   总被引:28,自引:0,他引:28  
第二次认知革命是后现代主义的革命。它的直接结果是促进了社会建构论的产生。社会建构论主张(1)知识是建构的,建构是社会的建构,而不是个体的建构。(2)人格、态度、情绪等心理现象并不存在于人的的内部,而是存在于人与人之间,是文化历史的产物。(3)语言并非是具有确定意义的透明的媒介,语言是先在的,规定了思维的方式。(4)没有超越历史和文化的普遍性知识,我们对于心理现象的理解是受时间、地域、历史、文化和社会风俗等制约的。(5)心理学家应该关注话语的作用,话语分析是心理学的基本研究方法。  相似文献

未成年人归因的内隐特征与攻击行为   总被引:9,自引:0,他引:9  
叶茂林  杨治良 《心理科学》2004,27(4):821-823
本研究使用投射法这一内隐社会认知的研究方法,考察了朱成年人罪犯群体与正常群体的攻击行为内隐社会认知过程的特征,结果表明:整体上而言,未成年人罪犯群体与正常群体的内隐归因方式存在显著差异,罪犯的内控程度要低于常人的内控程度。从而得出罪犯产生攻击性犯罪行为的原因之一是他们的归因存在偏差,支持了攻击行为成因的归因模型。未成年人男女两性在内隐的内外控方面不存在显著差异,且结果提示归因方式与女性罪犯的攻击行为没有必然联系。  相似文献

In metal–matrix composites (MMCs), interfacial bonding between the metal matrix and the ceramic reinforcement plays a crucial role in their mechanical performance. In the present study, B4C particles were cryomilled with an Al alloy to produce a composite powder, in which the B4C was uniformly distributed in nanocrystalline Al. The cryomilling developed a strong bond between the B4C and the Al, allowing the nanocrystalline Al to act as a coating with a strong ceramic–metal interface. This cryomilled composite powder was then introduced, as a reinforcement, into a conventional Al alloy to strengthen the material. After consolidation, the result was a bulk Al–matrix composite reinforced with B4C particles encapsulated in nanocrystalline Al. This composite exhibits greatly improved strength and stiffness.  相似文献

126 leaders and 624 employees were sampled to test the relationship between sources of motivation and conflict management styles of leaders and how these variables influence effectiveness of leadership. Five sources of motivation measured by the Motivation Sources Inventory were tested-intrinsic process, instrumental, self-concept external, self-concept internal, and goal internalization. These sources of work motivation were associated with Rahim's modes of interpersonal conflict management-dominating, avoiding, obliging, complying, and integrating-and to perceived leadership effectiveness. A structural equation model tested leaders' conflict management styles and leadership effectiveness based upon different sources of work motivation. The model explained variance for obliging (65%), dominating (79%), avoiding (76%), and compromising (68%), but explained little variance for integrating (7%). The model explained only 28% of the variance in leader effectiveness.  相似文献

The authors investigated the post-traumatic stress disorder (PTSD) symptoms of young adolescents who had been directly involved in a disaster in Tehran. The participants were 19 chlidren who had survived a boat sinking in Tehran's city park in 2002. By using the Post-Traumatic Stress Disorder Symptom Scale (PSS; E. B. Foa, D. S. Riggs, C. V. Dancu, & B. O. Rothbaum, 1993) as well as a clinical interview based on the definition cited in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV; American Psychiatric Association, 1994, p. 424), 16 participants (84.2%) were diagnosed with PTSD using the PSS and 17 (89.5%) were diagnosed with PTSD using the psychiatric interview.  相似文献

We present an analysis and results on the homogeneous nucleation of a dislocation loop under stress in a perfect crystal. By using a variational boundary integral method in the Peierls-Nabarro framework, we have determined the saddle-point configurations of embryonic dislocation loops and their associated activation energies under stress levels up to the ideal shear strength. The high-energy barriers under the usual levels of applied shear stresses, differing markedly from the ideal shear strength, confirm the widely held view that thermal motion should play no role in such nucleation. The result provides means for more definitive solutions of fundamental problems involving homogeneous nucleation of dislocation loops and has significant implications for models based on the mechanism of nucleation of dislocations from a perfect crystal.  相似文献

理论思维是人们在认识心理与行为的过程中,借助于概念、判断、推理等思维形式,运用比较、分析、综合、抽象、概括等思维方法,能动地反映客观现实的理性认识过程。心理学史课程的理论性很强,是当前中国高校所开设的心理学专业课程中,最适于培养学生理论思维的课程之一。教师可以在心理学史的教学过程中,利用比较列表法、范畴分析法以及主题式讨论等方法,来培养学生的理论思维。  相似文献

Nostalgic experience evokes emotions and activates the cognitive process of recalling and reconstructing information in memory. This study investigated the effects of nostalgia on creativity using experiments and questionnaires. Two-hundred-and-eighty university students were randomly assigned to experimental and control groups, in which participants received and completed different writing tasks (nostalgic experience vs. common life experience). They also responded to questionnaires measuring personality, nostalgia proneness, and creativity. Results showed that participants who were primed with nostalgic experience demonstrated higher creativity than the control group. In both groups, women demonstrated higher creativity than men. When specific aspects of the nostalgic experience were used to predict creativity, results showed that: (a) nostalgia triggered by social interaction and negative affect was positively related to creativity; (b) nostalgic experience containing tangibles positively predicted creativity; (c) the total number of triggers and the amount of, but not the positivity or salience of self in, nostalgia narrative contributed positively to creativity; and (d) higher agreeableness and openness, but not nostalgia proneness or other personality traits, were associated with higher creativity. Implications for both research and practice are discussed.  相似文献
