数字经济下智能化关键技术创新是离散制造企业向智能化转型的必然要求。本文基于离散制造特点与智能化技术应用，首先从需求设计、生产管理、信息管理和知识管理四个方面制定离散制造企业的智能化方案，并构建离散制造的智能化关键技术协同创新体系。其次以中国23个离散型智能制造企业为研究对象，建立智能化关键技术协同创新影响因素指标体系，并用熵权法和灰色关联分析法进行实证研究。实证结果表明：企业创新能力、企业智造潜力、企业协同动力、区域创新能力和外部环境支持对智能化关键技术协同创新起促进作用；在二级指标中，企业知识存量与政府补贴是智能化关键技术协同创新的主要影响因素。  相似文献   

Audience management,online turbulence and lurking in social networking services: A transactional process of stress perspective     

《International Journal of Information Management》2021

In social networking services (SNSs), users’ unclear understanding of the large and invisible audience increases the chances of online turbulence, which is a key source of SNS-induced stress. This growing phenomenon has gained increasing attention in academia and industry due to the undesirable consequences for users and SNS platforms. In this study, we draw from the transactional model of stress to examine how audience management strategies impact online turbulence and lead to neglected unintended audience concern and lurking. We also investigate the role of self-monitoring as a stress inhibitor. We test our model with data collected from 301 SNS users. The results show that the four types of audience management strategies have different effects on online turbulence, which significantly impacts neglected unintended audience concern especially when users have high self-monitoring skills. We believe that this work contributes, both from scientific and practical standpoints, to the understanding of the interventions and stressful responses of online turbulence in SNSs.  相似文献

“体育强则中国强”,体育在国家建设、人才培养、社会发展中具有举足轻重的重要作用。进入“新时代”,在复杂的国际形势下,在中华民族迈向伟大复兴“中国梦”的征程中,“以体育人”已成为社会的迫切需求。体育蕴含的自信自强、不畏强敌,顽强拼搏、永不言弃,团结协作、爱国奉献,德艺双修等精神,以及历代先贤对“武”的重视、国家领导人有关体育的论述等已为体育课程思政建设指明了方向、提供了活水源头。  相似文献   

Effects of an aerobic fitness test on short- and long-term memory in elementary-aged children

ABSTRACT

Meta-analytic evidence supports that exercise has benefits for short-term memory (STM) and long-term memory (LTM). However, only three studies with children have tested the differential effects of exercise on STM and LTM. The purpose of this study was to examine the effects of an aerobic fitness test on STM and LTM and to consider the moderating effects of grade level. Children (7–13 years of age) were randomly assigned to either perform an aerobic fitness test before (exercise prior) or after (exercise post) performing the Rey Auditory Verbal Learning Test (RAVLT) to assess memory. Memory was tested again after approximately 24 hours. There were significant differences in memory performance as a function of grade with 4^th and 6^th graders consistently outperforming 2^nd graders. For learning, Day 1 Retention, 24-hr recall, and Day 2 Retention, the exercise prior group performed better than the exercise post group. It is concluded that an aerobic fitness test performed prior to a declarative memory test benefits LTM as compared to when the aerobic fitness test is performed after the memory test.  相似文献   

Positivity and quality of college life of business students: The mediating role of learning approaches     

《Studies in Educational Evaluation》2020

Drawing upon the causal agency theory, this study examined the direct and indirect (via learning approaches) links between positivity and quality of college life (QCL) of business students in a transitioning market, Vietnam. Two studies were conducted to test these relationships using structural equation modeling. Findings from study 1, based on a sample of 428 business students, showed that positivity was positively related to QCL. Further, deep learning approaches mediated the relationship between positivity and QCL. Findings from study 2, based on a sample of 416 business students, reconfirmed the role of positivity in QCL. However, the indirect relationship between positivity and QCL was not significant, demonstrating that surface learning approaches did not mediate the relationship between positivity and QCL. The findings contribute to the literature on positivity in higher education by confirming the overarching role that positivity plays, directly and indirectly (via deep learning approaches), in QCL.  相似文献

体育产业供给侧改革:投入要素、行动逻辑与实施路径——基于社会主要矛盾转化研究视角     

沈克印  吕万刚 《中国体育科技》2020,(4):44-51,F0003

通过文献资料调研、实地考察、专家访谈等方法,基于社会主要矛盾转化视角,对体育产业供给侧改革的投入要素、行动逻辑与实施路径进行研究。研究认为:1)中国特色社会主义步入新时代,社会主要矛盾的转化对体育产业供给侧改革提出了新要求,而体育产业供给侧改革可以有效破解体育产业中不平衡和不充分的发展问题;2)推进体育产业供给侧改革的核心工作是通过改革与创新,优化产业结构,提高劳动力、土地、资本、制度等要素的投入力度,提高全要素生产率;3)行动逻辑是构建“强政府-强市场”结合模式,不仅要用好政府“有形之手”,也要放开市场“无形之手”,发挥市场在体育资源配置中的决定性作用。具体实践中,通过深化体制机制改革、促进产业跨界融合、实施产业创新驱动、补齐产业发展短板等途径推进体育产业供给侧改革。  相似文献
