A range of force (F) and velocity (V) data obtained from functional movement tasks (e.g., running, jumping, throwing, lifting, cycling) performed under variety of external loads have typically revealed strong and approximately linear F–V relationships. The regression model parameters reveal the maximum F (F-intercept), V (V-intercept), and power (P) producing capacities of the tested muscles. The aim of the present study was to evaluate the level of agreement between the routinely used “multiple-load model” and a simple “two-load model” based on direct assessment of the F–V relationship from only 2 external loads applied. Twelve participants were tested on the maximum performance vertical jumps, cycling, bench press throws, and bench pull performed against a variety of different loads. All 4 tested tasks revealed both exceptionally strong relationships between the parameters of the 2 models (median R = 0.98) and a lack of meaningful differences between their magnitudes (fixed bias below 3.4%). Therefore, addition of another load to the standard tests of various functional tasks typically conducted under a single set of mechanical conditions could allow for the assessment of the muscle mechanical properties such as the muscle F, V, and P producing capacities. 相似文献

情感模型的建立可以使计算机具备基本的情感识别和表达能力,在和谐人机交互方面有着广泛的应用.文中借助于Picard教授关于情感计算的理论,将线性系统理论和数字信号处理方法应用到情感信号与系统建模上,用信号很好地表示了人类的内在情感和情绪,并通过MATLAB仿真实验分析证明了模型的正确性.最后结合情感的高层次认知推理机制,将情感模型应用到情感虚拟人当中,形象地实现了情感对人脸表情变化的控制. 相似文献

学生核心素养的发展是21世纪各国教育领域普遍关注的核心问题。2006年欧盟正式出台了《欧洲终身学习核心素养建议框架》。2018年,欧盟对2006版核心素养框架进行了重新修订。与旧版相比,新版核心素养框架呈现出四方面新动向:更新了核心素养表述;更加强调核心素养发展的支持体系;核心素养发展趋于纵深化发展;由"教育的欧洲维度"向"欧洲教育领域"嬗变。欧盟核心素养框架得以修订存在两方面的动因,表面上看是源于旧版框架需要与时俱进的理性选择,深层原因则是欧盟试图在教育领域增强其干预能力,从而深化欧洲公民的"欧洲认同",最终增强欧盟的存在合法性。 相似文献

This study contributes to proactivity theory and debate on how universities meet competing stakeholder demands in an increasingly marketized higher education environment. We explore how the interplay between the stable facet of proactive personality and the situated behaviour of personal initiative influence academic performance. We hypothesized and found that students high on both these facets of proactivity achieve better academic grades than those low on both, or high in just one. Unexpectedly, high proactive personality with low personal initiative behaviour was the worst combination. Proactivity can be a valuable employability asset, which alongside academic grades is important to some employers as well as students and universities. We argue that nurturing student proactivity can therefore produce multiple benefits but with focus on the more trainable dimension of personal initiative behaviour. To this end we provide practical guidance for university curriculum design to simultaneously enhance graduate employability and academic performance. 相似文献

欧盟于20世纪90年代末开始重视创业教育,为了应对创业教育全面推行所产生的师资缺口,欧盟提出培养“创业型教师”的目标,并且从职前教师教育、教师持续专业发展、国家(地区)支持体系和地方学校支持等四个方面展开行动,不论在理论方面还是实践方面都有开拓意义.借鉴欧盟“创业型教师”教育的发展经验,我们应高度重视高师院校的创业教育,构建“创业型教师”教育“生态系统”,鼓励和支持区域间建立伙伴合作,从而有效推动我国的创业教师教育. 相似文献

ABSTRACTLateral ankle stability and how it changes in different footwear has been investigated for years. Research, however, has shown a lack of reliability or sensitivity of available methodologies. This study aimed to evaluate the test-retest reliability and sensitivity of a novel lateral stability protocol, the Submaximal Lateral Shuffle Test (SLST). We recruited 11 and 40 participants to assess reliability and sensitivity of the SLST, respectively. Participants performed the SLST in footwear that differed in collar height and upper stiffness. ICC values showed good to excellent reliability in peak ankle angles and moments, ground reaction forces, impulses, stance time, and performance time. Significantly lower peak inversion and adduction angles and lower medio-lateral push off peak forces were found in the high cut shoes compared to the low cut shoes. The medio-lateral landing peak force showed lower forces in the high cut shoes. The smallest worthwhile change indicated meaningful differences in 70.0–82.5% of participants for inversion, adduction, medio-lateral landing peak, and push off peak forces. These results, however, were not systematic such that there was not a consistent direction of the difference for all participants. In conclusion, the SLST is a promising protocol to further investigate lateral stability in footwear. 相似文献

当前后发企业的技术寻求型的跨国并购发展迅速,然而并后成功实现整合并获得技术升级的企业并不多见,一直以来是困扰后发跨国企业的一大难题。本研究在二次创新理论的基础上构建了全球化进程中的动态演化模型,试图通过组织学习与组织合法性两个维度,解释后发跨国企业如何在跨国并购过程中实现技术能力的积累与提升。通过追踪研究中国民营车企吉利集团十余年内多次跨国并购行为,我们发现：吉利集团凭借三次螺旋上升的互补资产寻求型跨国并购,利用组织内外部合法性的杠杆效应,确保了并购后组织学习的有效性,正是通过这种全球二次创新的动态演进模式,吉利集团成功实现了后发者的追赶。 相似文献
