客家艺术的乡土情缘与文化传承

客家艺术是特定地域文化长期积淀的产物,是适应环境逐步个性化的结果,它具有独特的地方文化内涵。乡土作为重要的文化资源和创作源泉,使客家艺术更具深厚的个性文化底蕴。文章在现实境遇下,从乡土情缘与文化传承两个层面对客家艺术进行了探讨。     

Measurement properties and feasibility of the Loughborough soccer passing test: A systematic review

The purpose of this paper was to systematically review the literature and examine the research methodological quality, measurement properties and feasibility of the Loughborough Soccer Passing Test (LSPT). Databases were searched up to June 2017. Twenty five studies fulfilled the eligibility criteria. The main methodological limitations of the studies were the small sample size and the lack of information on participants and eligibility criteria. Results showed that test-retest reliability of the LSPT was moderate to excellent. Good discriminative validity was found between playing levels and ages. The LSPT was positively correlated with sprint, dribbling, and agility test; however, a weak correlation was established with in-game performance. Test responsiveness (an ability to detect change over time) to some external interventions was observed in studies. Adjusted Cronbach’s alpha (α = 0.67), smallest worthwhile change (SWC = 0.8–3.8) and minimal detectable change (MDC₅₀ = 1.9–11.3) were calculated based on available data. The findings indicate that the LSPT has acceptable test-retest reliability and discriminative validity. However, it may not be a feasible and effective way to interpret the intra-individual change of skill performance in practice. Future work should be undertaken to establish additional measurement properties of the LSPT, and to improve its practical feasibility.     

功能性训练在羽毛球运动员力量训练中的应用研究

通过文献资料并结合训练实践,探讨功能性力量训练对羽毛球运动员力量发展的意义与应用价值;研究认为,功能性力量训练对羽毛球运动员专项体能的发展及运动损伤的防治有着积极的作用,尤其腰腹功能性力量训练及上肢神经肌肉控制训练对羽毛球运动员专项技能发挥有着不可替代的优势。未来除了进一步完善功能性力量训练体系外,也应加强功能性训练其他方面在羽毛球运动中的应用实践研究。     

三种99mTc-HSA生物性能的比较

本制备了三种标记率在90％以上的^99mTc-HSA(^99mTc标记的人血清白蛋白）：^99mTc标记未修饰的HSA，699mTc标记二氯亚锡预还原的HSA及FAS（甲眯基亚磺酸）预还原的HSA，然后在小鼠体内进行了生物分布实验，结果表明：^99mTc标记二氯亚锡预还原的HSA在血中的摄取和滞留均优于第一种标记物，而^99mTc标记FSA预还原的HSA在血中的滞留也强于未修饰的标记物。这说明^99mTc标记预还原后的HSA比未修饰HSA的配合的牢固性确实有所提高，标记物的生物性能也得到改善，从而为这类药物在实际中更好地应用做了有益的探索性工作。     

Individual and collective agencies in China's curriculum reform: A case of physics teachers

This study explores how physics teachers in a high school negotiate the relationships between individual and collective agencies in the context of the on-going curriculum reform in China. Drawing on Bandura's social cognitive theory, the study employs ethnographical methods including observation, interviewing, and the researcher's and teachers’ reflective journaling through the researcher's involvement with various school activities. The findings indicate that collective teacher agency creates a platform for individual teachers’ professional development, a conducive culture for teacher collaboration, and provides concrete examples that individual teachers can constantly refer to, reflect upon, and learn from for reform implementation. The results offer an understanding of the influences underlying physics teachers’ agency deployment as they engage with curriculum reform processes, especially the negotiation between individual and collective agencies. The findings justify a case for preparing physics teachers on how to deploy both individual and collective agencies in the face of the complicated social structures and ultimately shed light on the desired curriculum decentralization in the Chinese school system.
