采用文献资料法、专家访谈、逻辑分析等方法,探讨竞技体育跨项选材现实动因和一般规律,并针对目前竞技体育领域跨项选材存在问题进行理性反思。我国竞技体育领域跨项选材呈现以下规律:借助身体素质优势,由运动基础大项向其他项目流转;抓住关键技术环节,在奥运各大项之间高频互跨;依据项目特征和制胜规律,在同一项群互跨;依托综合竞技能力迁移,从早期专项化项目向晚期专项化项目流转。针对跨项选材中存在的理论与实践方面的问题,提出针对性建议:未来竞技体育跨项选材应精准把握项目特征,科学构建指标体系;深化跨项规律认识,准确捕捉跨项时机;科学划定选材范围,引导人才合理流动;加强跨项统筹管理,建立健全保障机制。 相似文献

The focus of this paper is on a group of pupils with reading and writing difficulties who have been participating in an intervention study using assistive technology. That intervention study contained supervised training sessions with reading and writing tasks using an iPad with special supportive applications. The current study is a qualitative investigation of whether there has been any transfer from the intervention, to the pupils’ everyday school activities. Interviews with pupils and their teachers and observations during classroom lectures have been used to collect data. The results show that the pupils were positive to the assistive technology (the applications on the iPads), they found the apps easy to learn how to use and they appreciated the benefits they could give. Even so, only a few of the pupils had found use for and continued to use the tools after the intervention period finished. Possible reasons are that when the novelty wore off, students reverted to their usual study habits and that older students with many teachers and different classrooms were less able to adapt to using the apps. To improve transfer, it is suggested to introduce assistive technology earlier to students, in the younger grades, before study habits have been formed and to inform teachers about the use of AT in the classroom, including what is available and how it can benefit students. 相似文献

在足球劳动合同到期后球员即可自由转会的现行转会制度下,球员转会协议在体育和经济层面仍存在充分的现实必要。由于规则层面的缺陷、实践层面的误解以及学理层面的不足,球员转会协议的法律性质仍然存在不明,甚至直接造成法律争议的发生。对涉事的两家俱乐部而言,球员转会协议并非所谓球员的“联盟权”或经济权的交易,而是为实现希望加盟新俱乐部的球员注册变更的重要先决条件,即主要通过支付转会费的方式换取原俱乐部解除未到期的足球劳动合同之同意;对球员与俱乐部而言,经球员确认的转会协议构成他们之间的劳动合同的附条件解除。现行转会制度层面下的足球劳动关系的人身隶属性与足球劳动合同的稳定性乃是球员转会协议存在的诱因,全面系统地分析俱乐部竞争性的平衡与球员劳动权益的保护有助于解决球员转会协议实践中发生的争议。 相似文献

引用许可的引入和推广对我国出版业的版权保护和期刊的健康发展具有重要的现实意义。基于文献调研和网站调研的分析结果表明,国内期刊尚未普遍引入和形成引用许可申请准则,对版权保护不够重视;而国外期刊的引用许可申请较为完善和规范,可适用于不同场景下的引用许可要求。对国内期刊而言,为建设世界一流期刊,各专业领域期刊需加强版权保护意识,率先形成本领域内的引用许可共识;并结合自身发展和国际成熟经验,推广切实可行的引用许可准则,有助于加快学术出版、促进学术交流、规范学术道德,提升国际影响力。 相似文献

为观察气膜厚度对反气泡稳定性的影响,通过加热反气泡内外溶液来加热气膜内气体从而改变气膜厚度。实验发现:在一定温度范围内,加热反气泡气膜可以延长其稳定时间,但是当加热反气泡气膜使其厚度超过其稳定存在的阈值时,反气泡的稳定性会急剧下降甚至无法产生反气泡;在一定温度范围内温度对溶液表面张力影响很小,这使得文中实验数据合理化。本文为反气泡稳定性的理论研究提供实验支持,并考虑到气膜厚度为微米级,可为微米级气膜传热提供实验素材。 相似文献

In this article, we draw on a survey conducted with elite upcoming lawyers from all around the world to shed new light on the ethical acceptability of file sharing practices. Although file sharing is typically illegal, our findings show that lawyers overwhelmingly perceive it as an acceptable social practice. The main criterion used by lawyers to decide on the ethical acceptability of file sharing is whether or not the infringer derives any monetary benefits from it. Further, our findings show that lawyers in the public sector (including judiciary and academia) are even more tolerant of online copyright infringement than those in the private sector. Interestingly, our data suggests that this is largely the result of self-selection: lawyers who lean more on the side of broad disclosure and social sharing tend to orient themselves toward the public sector. Implications for the current state of the debate on the reform of copyright law are discussed. 相似文献

Coopetition, i.e., cooperation between competing actors, has become a pervasive strategy for innovative firms. The primary focus of studies investigating coopetition centers on inter-firm relationships, highlighting the benefits, limits and configurational patterns of cooperative relationships between competing firms. Only a small, emerging group of studies seeks to extend the concept to the intra-firm level, stressing the existence and effects of competition and cooperation between units that are part of the same organization. This paper contributes to this latter group by investigating the effects of internal coopetition on knowledge and innovation sharing and highlighting the fundamental role of knowledge brokers in managing the resulting tensions. Based on a qualitative case study of the video game publisher Ubisoft, we stress how the tensions raised by internal coopetitive settings limit knowledge sharing between units, and we analyze the mechanisms through which the knowledge broker helps to overcome these limits. We identify three main functions of this knowledge broker that allow the promotion of knowledge and innovation transfer to occur between coopeting units: (1) protecting the unit’s competitive advantage by introducing a lagging principle in the transfer process, (2) reducing sharing costs by standardizing innovative solutions, and (3) enhancing awareness of and trust in innovative solutions by centralizing knowledge diffusion. 相似文献
