不确定性视阈下我国民办高等教育发展的政策调整     

周江林 《民办教育研究》2009,(7)

不确定性是客观世界的内在本性。不确定性问题是关于事物相互联系尤其是因果联系的一种哲学研究。近30年来,尽管我国民办高等教育实现了跨越式发展,但依然存在着生存基础的不稳定性、制度供给的非连续性和社会认知的模糊性等不确定性因素。因此,在不确定性视阈下,我国政府应该在稳固民办高等教育的生存基础、增加制度供给以及提高社会认同等方面作出相应的政策调整。  相似文献   

一维谐振子不确定关系的变分推导法     

罗凌霄  李汝恒 《天水师范学院学报》2005,25(2):29

用基于普遍形式的不确定关系之上的变分方法推出了一维谐振子的含有量子数的等式型不确定关系。给初学者介绍这样简单明了的东西,可以有效地加深他们对不确定关系的理解,并且避免形成不确定关系只能表述为不等式形式这种错误观念。  相似文献   

论近古汉语副词“忒煞”——兼与“忒”比较     

汤京普  商华 《衡水学院学报》2009,11(2)

副词"忒煞"在近古时期的文献中为"太甚"之词,通过对该时期的大量语料研究发现:一、近古时期"忒煞"主要集中使用于南方;二、近古时期"忒煞"使用频率远低于"忒",而造成现象二的主要原因是"忒煞"的不确定性.  相似文献   

Examining the moderating effect of individual-level cultural values on users’ acceptance of E-learning in developing countries: a structural equation modeling of an extended technology acceptance model     

Ali Tarhini  Kate Hone  Xiaohui Liu  Takwa Tarhini 《Interactive Learning Environments》2017,25(3):306-328

In this study, we examine the effects of individual-level culture on the adoption and acceptance of e-learning tools by students in Lebanon using a theoretical framework based on the Technology Acceptance Model (TAM). To overcome possible limitations of using TAM in developing countries, we extend TAM to include subjective norms (SN) and quality of work life constructs as additional constructs and a number of cultural variables as moderators. The four cultural dimensions of masculinity/femininity (MF), individualism/collectivism, power distance and uncertainty avoidance were measured at the individual level to enable them to be integrated into the extended TAM as moderators and a research model was developed based on previous literature. To test the hypothesised model, data were collected from 569 undergraduate and postgraduate students using e-learning tools in Lebanon via questionnaire. The collected data were analysed using the structural equation modelling technique in conjunction with multi-group analysis. As hypothesised, the results of the study revealed perceived usefulness (PU), perceived ease of use (PEOU), SN and quality of work life to be significant determinants of students’ behavioural intention (BI) towards e-learning. The empirical results also demonstrated that the relationship between SN and BI was particularly sensitive to differences in individual-cultural values, with significant moderating effects observed for all four of the cultural dimensions studied. Some moderating effects of culture were also found for both PU and PEOU, however, contrary to expectations the effect of quality of work life was not found to be moderated by MF as some previous authors have predicted. The implications of these results to both theory and practice are explored in the paper.  相似文献

中国高技术产业技术创新动态能力演化研究     

李志春  李海超 《科技管理研究》2019,39(9)

高技术产业的蓬勃发展过程中技术创新的作用至关重要,因此高技术产业技术创新成为全世界各国竞争的核心与学术研究的热门。为了探究高技术产业技术创新动态能力的演化过程,本文根据经典物理力学理论,构建中国高技术产业技术创新动态能力演化三维动态模型,从技术创新动态能力的主导逻辑思维出发,以能力广度、能力深度、能力的生命周期三个角度,对高技术产业技术创新动态能力演化模型进行维度分析。研究表明高技术产业技术创新动态能力演化过程在空间内形成类似于S型的曲面。  相似文献   

技术成果评价的社会学分析   总被引：8，自引：1，他引：8  

戴建生 《科学学研究》2001,19(1):70-77

随着科技的发展和知识经济社会的来临 ,同行评议在技术成果领域受到强有力的挑战 ,因此 ,我们是否应该寻求更为客观、公正与有效的评价模式 ?本文以社会学的视角 ,深入分析了同行评议内在的缺陷与不足、技术成果评价的原则和标准以及科学技术是第一生产力的社会学意涵。文章认为 ,同行评议已不适用于技术成果的评价 ,我们应当建立市场和社会相互结合的评价机制。评价不仅要考察技术成果的经济效益 ,还要评估其人文效应。  相似文献   

Battles for technological dominance: an integrative framework   总被引：3，自引：0，他引：3  

Fernando F. Suarez 《Research Policy》2004,33(2):271-286

This paper proposes an integrative framework for understanding the process by which a technology achieves dominance when “battling” against other technological designs. We focus on describing the different stages of a dominance battle and propose five battle milestones that in turn define five key phases in the process. We review the literature from several disciplines to identify the key firm- and environment-level factors that affect the outcome of a technology battle and posit that the relative importance of each factor will vary depending on the phase considered. Our framework complements and extends existing literature and has implications both for theory and for management practice.  相似文献   

不确定性条件下企业信息系统的云化决策方法     

苗虹  宋倩倩  孙金生  王念新  李鹏  葛世伦 《软科学》2016,(8):129-132

企业在决策本地化信息系统转换为云模式的软件即服务时面临着技术市场发展、云化收益、决策者风险偏好等诸多不确定性。针对该决策,引入前景理论考虑了维持现状偏好、追求管理时尚等心理行为,依据交易成本理论和技术组织环境理论提取了决策指标,以未来不同的软件即服务市场成熟度作为前景状态,计算各备选信息系统云化迁移的综合前景值,形成不确定性条件下企业信息系统的云化决策方法。同时,应用该方法实例分析了一家企业,并与基于期望值的灰色随机多准则决策方法进行了比较,说明了该方法的可行性和合理性。  相似文献   

Is the Internet a US invention?—an economic and technological history of computer networking     

David C. Mowery  Timothy Simcoe 《Research Policy》2002,31(8-9)

Although the inventions embodied in the Internet originated in a diverse set of industrial economies, the US was consistently the source of critical innovations and an early adopter of new applications. Why did other nations, including several that made important inventive contributions to the Internet, not play a larger role in its development, particularly in the creation of new business organizations, governance institutions, and applications? We argue that the role of the US “national innovation system” in the creation of the Internet echoes several key themes of US technological development before 1940. The presence of a large domestic market, a set of antitrust and regulatory policies that weakened the power of incumbent telecommunications firms, and a diverse private/public research community that was willing to work with both domestic and foreign inventions were important preconditions for US leadership in computer networking innovation.  相似文献
