基于日语专业四级考试的“基础日语”课程教学改革的思考

“基础日语”课程是高校日语专业低年级的核心课程,它涉及学生基本技能的培养与训练、知识体系的学习与构建,对学生综合能力的提高起着重要的奠基作用。日语专业四级考试是对高校日语教学情况的检测,同时也可以对教学起到及时有效的反馈作用。基于二者之间的这一关系,该文从日语专业四级考试的角度对“基础日语”课程教学进行思考,提出改革措施,以期促进日语教学质量的提高。

Effects of plyometric vs. resistance training on skeletal muscle hypertrophy: A review

ObjectiveIn this review, we critically evaluate studies directly comparing the effects of plyometric vs. resistance training on skeletal muscle hypertrophy.MethodsWe conducted electronic searches of PubMed/MEDLINE, Scopus, SPORTDiscus, and Web of Science to find studies that explored the effects of plyometric vs. resistance training on muscle hypertrophy.ResultsEight relevant studies were included in the review. Six studies compared the effects of plyometric vs. resistance training on muscle hypertrophy, while 2 studies explored the effects of combining plyometric and resistance training vs. isolated resistance training on acute anabolic signaling or muscle hypertrophy. Based on the results of these studies, we conclude that plyometric and resistance training may produce similar effects on whole muscle hypertrophy for the muscle groups of the lower extremities. Therefore, it seems that plyometric training has a greater potential for inducing increases in muscle size than previously thought. Despite the findings observed at the whole muscle level, the evidence for the effects of plyometric training on hypertrophy on the muscle fiber level is currently limited for drawing inferences. Compared to isolated resistance training, combining plyometric and resistance exercise does not seem to produce additive effects on anabolic signaling or muscle growth; however, this area requires future study. The limitations of the current body of evidence are that the findings are specific to (a) musculature of the lower extremities, (b) short-term training interventions that lasted up to 12 weeks, and (c) previously untrained or recreationally active participants.ConclusionThis review highlights that plyometric and resistance training interventions may produce similar effects on whole muscle hypertrophy, at least for the muscle groups of the lower extremities, in untrained and recreationally trained individuals, and over short-term (i.e., ≤12 weeks) intervention periods.

海归高管与企业创新效率:助力还是阻力？

以2008-2017年A股上市公司为研究对象,用三阶段DEA模型从技术研发和转化两个阶段测度企业创新效率并分析其与高管海外经历的关系。结果表明,高管海外经历能提高企业创新效率,且不同学历层次和专业背景对企业创新效率影响具有明显差异。进一步研究国有属性和风投注资视角下的影响差异,发现相较于非国有企业,具有海外经历的高管在国有企业任职更能发挥对技术创新的促进效应;在有风险投资进入时,具有经管专业背景的高管更能发挥自身优势,促进企业技术创新。
