单板滑雪U型场地技巧优秀运动员落地稳定性研究

近年来,随着单板滑雪U型场地技巧项目的快速发展及国际运动成绩的快速提升,我国运动员在训练方面遇到了很多问题,如运动员在完成高难度的空中技术动作后,在落地时总是出现失误,直接影响运动员在比赛中的成绩.本文采用文献资料、专家访谈、录像分析等研究方法,对黑龙江省单板滑雪U型场地技巧优秀运动员的落地稳定性进行了分析,具体涉及运动员成套动作落点分析、滑行路线分析和运动员平衡能力,研究结果认为,运动员的平衡能力差和落点区域的不同选择是导致落地稳定性差的主要原因.为帮助单板滑雪U型场地技巧项目备战2018年平昌冬奥会提供了一定的理论依据.     

网络信息资源著作权风险规避中的委托代理关系

[目的/意义]通过对网络信息资源著作权风险中著作权人与网络服务提供者的博弈分析,在利益均衡的基础上提出著作权风险规避的策略。[方法/过程]运用委托代理理论的基本原理,分析著作权人与网络服务提供者的委托代理关系,构建信息不对称条件下著作权人为风险中性和风险规避时的委托代理模型,并进一步对两种情况下的各绩效指标进行探讨。[结果/结论]在委托代理机制下,著作权人与网络服务提供者在风险规避上的利益具有一致性;在两种不同情况下著作权人的激励程度、网络服务提供者的努力程度以及总的期望收益均有显著变化;著作权人的激励程度以及双方的最终收益与网络服务提供者的努力程度、努力成效、风险规避程度、项目完成能力等因素密切相关。基于此,可以通过健全奖惩激励机制、完善利益补偿机制、强化监督管理机制来规避网络信息资源著作权中的风险问题,实现委托代理双方收益的帕累托最优。     

我国传统养生理论中的经络学说

根据我国传统养生理论的观点,结合人体运动及针灸、气功修炼实践,对经络学说作了全面的剖析,提出:人体运动,经络通畅;经络既通,其形乃彰;经络失常,人体衰老;疏通经络,延年益寿等观点,为人们的运动健身和养生保健提供有益的借鉴。     

浅谈色彩在版面设计应用中的误区及对策

版面改革,即着重从版面设计和色彩,线条等运用上着手,加强报纸的视觉冲击力,力显除新闻价值以外能吸引受众的因素。因此．色彩运用成为了“版面改革”的重头之戏。很多报纸将“改革”重点放在了色彩如何运用上。

THE MEDIA AND ENVIRONMENTAL ISSUES IN HONG KONG 1983-95

This study tests the agenda-setting hypothesis for the environmentalissue in Hong Kong from 1983 to 1995. It was found that theagenda-setting hypothesis was supported for the initial periodof five and a half years. In the subsequent period of sevenand a half years, despite the increased media coverage of theissues, there was a significant drop in the perceived salienceof the environmental problem. This may be due to the dilutionof public attention as a result of diversity in the news agendaand reporting of local environmental problems as ‘soft’news. It was also found that the environmental issue failedto compete with other prominent issues directly affecting thepublic. The mass media played a much less important role inkeeping the environmental issue on the public agenda at thelater stage.     

Undergraduates’ learning experience and learning process: quantitative evidence from the East

This article examines the construct validity of the Course Experience Questionnaire (CEQ) in Hong Kong and investigates the similarities and differences in the process of learning among students in different disciplinary studies. It is based on a survey of 1,563 undergraduate students in two disciplines, humanities and sciences, and of principally Chinese ethnicity. Findings from exploratory and confirmatory factor analyses support the scale structure of the four subscales of a modified version of the CEQ (good teaching, clear goals and standards, appropriate work, and appropriate assessment) in a non-Western context and could provide a basis for cross cultural research and international benchmarking. While there was variation across subgroups, there was a genuine pattern of relationships between the perceptions of learning environment and learning strategies shown by structural modeling. This information could be used to inform the design of discipline-specific programs in the new curriculum.     

Feedback complexity and corrective efficiency

College undergraduates read a 2400-word passage, responded to 16 multiple-choice questions, and received one of four types of feedback following their responses. Complexity of feedback was inversely related to both error correctability and criterion efficiency taken as a ratio of feedback study time to post-test corrects. The results were discussed in terms of depth of processing and instructional comprehension.
