国外大学知识转移治理研究述评     

李勤  姚笑秋  朱太球 《科技管理研究》2015,(7)

知识转移已成为一个战略性问题,大学在推动并促成学术研究商业化中的作用千差万别,大学与产业之间互动明确的管理模式以及知识转移过程的识别都不是一件简单的事情。通过对现有关于大学知识转移治理的文献进行归纳和整理,分别从大学知识转移的模式和机构、知识转移机构中的知识转移治理、知识转移制度以及知识转移的绩效和激励等方面,对国外大学知识转移治理研究进行综述,在此基础上提出大学知识转移治理的研究局限以及未来展望,明确大学知识转移治理的进一步研究方向。  相似文献   

一叶兰的组织培养和快速繁殖     

周勇  雷强军  刘良宏 《科协论坛》2008,(7)

作者以根状茎为起始外植体,采用常规手段对一叶兰的快繁技术的研究.结果表明,以MS为基本培养基,附加一定浓度的BA,根状茎中的顶芽和腋芽都有较好的分化效果,诱导率可达75%;诱导出的顶芽或腋芽仍转入以MS为基本培养基,并添加适量浓度的CPPU、KT和NAA,增值系数可达2.5左右;所得增值芽在Ms Ac 1g/L的培养基中诱导生根,生根率达到了92%.  相似文献   

石斛兰组培快繁研究初探     

黄萍萍  潘伟彬  张永柏  廖福琴 《闽西职业技术学院学报》2003,5(3):85-86

在石斛兰组培快繁过程中,6-BA和NAA对类原球茎的诱导有重要作用。6-BA、KT和NAA的合理组配对类原球茎的增殖和苗的分化有促进作用。IBA和添加物香蕉是石斛兰的生根和壮苗的关键。  相似文献   

不确定性规避与员工创新绩效——知识转移的中介作用     

刘追  郑倩  孔令英 《软科学》2016,(10):113-117

以科技型企业员工为研究对象,基于收集到的370份有效样本,采用层次回归的分析方法,分析了不确定性规避对员工创新绩效的影响,探讨了知识转移在两者之间的作用机理。结果发现:不确定性规避对员工创新绩效和知识转移均有显著的负向影响,知识转移对员工创新绩效有显著的正向影响,知识转移在不确定性规避与员工创新绩效的关系中起着部分中介作用。  相似文献   

Soccer

Female athletes are at least twice as likely to sustain an anterior cruciate ligament injury than male athletes. The underlying cause of ACL injury is multifactorial. However, several researchers have identified knee joint laxity as a possible contributing factor. The purpose of this study was to provide a comparison of knee joint laxity between male and female collegiate soccer players and male and female non‐athletes. Thirty‐nine (19 male, 20 female) apparently healthy, collegiate athletes from the University of Texas at El Paso's 2001‐2002 women's intercollegiate soccer team and men's club soccer team, and forty (20 male, 20 female) non‐athletic students volunteered to participate. All participants were tested bilaterally using the KT‐1000 MEDmetric knee joint ligament arthrometer. Three tests were used to determine anterior laxity: passive displacement, active displacement, and the Lachman test. The mean passive displacement, mean active displacement, and Lachman (only for the left leg) were significantly lower for the athletic group than for the non‐athletic group. There were no significant differences found between males and females for the passive and active drawer tests. However, females had significantly more laxity than males in the Lachman test. These findings suggest that strength and conditioning may play a more significant role in knee joint laxity than the sex of the individual.  相似文献
