基于技术环境论的技术扩散模型研究

本文从技术环境论的角度探讨技术扩散现象。技术扩散度受技术环境承载力的制约,并且与相关技术的相互作用有关。本文主要研究了特定环境下单技术扩散模型及具有替代型技术关系的“新”技术扩散模型。     

中国获取海外石油资源的战略博弈

在经济全球化的今天,石油作为具有战略意义的资源对于国家经济发展和安全起着举足轻重的作用,为保障我国石油的稳定供给,国家出台了一系列政策鼓励企业“走出去”获取海外的石油资源,在这种形势下,为获取稀缺的石油资源,我国不可避免的与各利益相关国展开复杂的战略博弈。因此,作为石油输入大国的中国,如何选择正确的能源战略进行博弈成为一个亟代解决的课题。本文于此提出了一种基于AHP的博弈模型,为中国获取海外石油资源的战略博弈提供一种全新的解决思路。接着,本文以近年来愈演愈烈的中国（石油输入国）、俄罗斯（石油输出国）双方的石油战略博弈作为实际案例,构建出中国的石油获取能力与俄罗斯利益最大化能力的指标体系;然后详细的分析了中国与俄罗斯的战略博弈过程;最终得出博弈结果：中、俄双方只有以”大合作小竞争”的战略思想作为理性的选择,方能使博弈的双方同时达到利益的最大化目的。同时,文章在最后对博弈模型尚需研究和完善的地方进行了相应探讨。     

高等教育机会与正义原则^[1]

本在理论层面分析了我国高等教育体制存在的效率至上的原则以及选优行能的精英主义倾向,这种从社会功利出发的高等教育体制是以牺牲社会公正为代价的,由于忽视了高等教育机会分配中的正义性,社会效率的实现也最终受到影响。在强调正义原则的基础上,本探讨了高等教育大众化中制度选择的一些实践性问题。     

Cushioning and lateral stability functions of cloth sport shoes

In this study, we evaluated the protective functions of cloth sport shoes, including cushioning and lateral stability. Twelve male students participated in the study (mean +/- s: age 12.7 +/- 0.4 years, mass 40.7 +/- 5.9kg, height 1.50 +/- 0.04m). Cloth sport shoes, running shoes, basketball shoes, crosstraining shoes, and barefoot conditions were investigated in random sequence. Human pendulum and cutting movement tests were used to assess cushioning performance and lateral stability, respectively. For cushioning, the running shoes (2.06 body weight, BW) performed the best, while the cross-training shoes (2.30 BW) and the basketball shoes (2.37 BW) both performed better than the cloth sport shoes (2.55 BW) and going barefoot (2.63 BW). For the lateral stability test, range of inversion--eversion was found to be from 3.6 to 4.9 degrees, which was far less than that for adult participants (> 20 degrees). No significant differences were found between conditions. All conditions showed prolonged durations from foot-strike to maximum inversion (66-95 ms), which was less vigorous than that for adult participants (< 40 ms) and was unlikely to evoke intrinsic stability failure. In conclusion, the cloth sport shoe showed inferior cushioning capability but the same lateral stability as the other sports shoes for children.     

Biomechanics of Tai Chi: a review

Tai Chi Chuan is a favourite form of exercise throughout the world and has drawn increasing research interest from international scientists. Biomechanical research into Tai Chi has grown substantially and has provided evidence of the beneficial effects of Tai Chi exercise on health, fitness, and prevention of falls. This paper reviews studies that have explored the biomechanical aspects of Tai Chi, such as balance, kinematics, kinetics, strength, and neuromuscular activities.
