从职业网球运动看超小周期“多课次”的训练模式

本文通过查阅大量文献资料,结合当前职业网球运动员训练及参赛周期特征与传统大周期训练模式产生的冲突,对新周期形态与训练定式——超小周期＂多课次＂训练模式进行探讨,以便于能给教练员和运动员提供实质性的建议和思考。     

我国房地产市场泡沫之测度及风险预防

房地产业是一国的支柱产业,但是随着我国经济的发展,人民币的升值,资产价格的虚增,房地产投资已经过热。多国的经验证明,房地产泡沫一旦爆裂,对一国的经济而言将会是致命的打击。本文在分析现阶段房地产泡沫的成因后,针对性地提出抑制房地产泡沫的有效措施:为了防止泡沫破裂引起的经济重创,应采用挤压、引导等温和手段来治理房地产泡沫。     

当前房地产人才培养存在的问题与对策

房地产人才培养要适应房地产行业的发展和用人单位及社会的需求。面对新的行业环境和用人需求规格,高校房地产人才培养需要调整与完善。本文从当前我国房地产人才培养存在的一些问题谈起,对新形势下房地产人才培养如何适应行业和社会的需求作初步的探讨与思考。     

我国房地产泡沫的原因分析

近年来我国房地产价格节节攀升,房地产泡沫引起了广泛关注。造成房地产泡沫的主要原因包括改革惯性作用、土地资源稀缺性、商业银行过度信货、开发商炒作及市场预期等。房地产泡沫治理应从房地产泡沫产生的原因出发。     

关汉卿杂剧的叙事品格

近几年来，传统戏剧的叙事品格已为研究者所重视。关汉卿杂剧是我国古代叙事艺术中的瑰宝，它在叙事时间、叙事视角、叙事话话等方面所作的探索，表征了我国古代戏曲发展至元初已臻成熟，具有深远的历史意义。     

The influence of an afternoon nap on the endurance performance of trained runners

The effectiveness of a nap as a recovery strategy for endurance exercise is unknown and therefore the present study investigated the effect of napping on endurance exercise performance. Eleven trained male runners completed this randomised crossover study. On two occasions, runners completed treadmill running for 30?min at 75% ?O_2max in the morning, returning that evening to run for 20?min at 60% ?O_2max, and then to exhaustion at 90% ?O_2max. On one trial, runners had an afternoon nap approximately 90?min before the evening exercise (NAP) whilst on the other, runners did not (CON). All runners napped (20?±?10?min), but time to exhaustion (TTE) was not improved in all runners (NAP 596?±?148?s vs. CON 589?±?216?s, P?=?.83). Runners that improved TTE after the nap slept less at night than those that did not improve TTE (night-time sleep 6.4?±?0.7?h vs. 7.5?±?0.4?h, P?r^{2 ?} =??0.76, P?=?.001). In runners that improved TTE, ratings of perceived exertion (RPE) were lower during the TTE on NAP than CON compared to runners that did not improve (?0.4?±?0.6 vs. 0?±?0, P?=?.05). Reduced exercising sense of effort (RPE) may account for the improved TTE after the nap. In conclusion, a short afternoon nap improves endurance performance in runners that obtain less than 7?h night-time sleep.     

原地连续纵跳的运动生物力学特征研究

为研究原地连续纵跳的运动生物力学特征,运用录像拍摄与三维测力同步测试的方法对其研究发现,不同频率作用下的时间参数存在一定差异,随着纵跳频率的增加,时间参数都表现出逐渐减小的趋贽.同一频率作用下随着运动时间的延长,支撑时间逐渐增人.蹬伸力峰值随着连续纵跳运动时间的延长呈现明显逐渐减小的趋势,不同频率原地连续纵跳蹬伸力峰值对起跳效果的影响程度是不同的;缓冲冲量和蹬伸冲量随运动时间的延长,也都呈现出明显的逐渐减小的趋势,并且运动前期的恢复系数人于1.     

金融科技概念辨析、发展历程梳理及前景展望

运用比较分析、抽象概括的方法,深入辨析金融科技、科技金融和互联网金融等相关概念的异同及与实体经济的关系,在此基础上以主要支撑技术及其典型应用为划分依据分析金融科技的发展历程,得出的结论是:金融科技先后经历了电子化金融、互联网金融和场景化金融等发展阶段,金融与科技的融合逐渐加深。随着人工智能、5G、区块链等前沿技术的应用和监管的完善,金融科技产业将迎来新一轮重大发展机遇,金融科技创新在促进实体经济高质量发展方面有望发挥更大的作用。     

Ethnographical mapping of thick places – teaching and learning practices in teacher training schools

The aim of this study is to use an ethnographic method in order to map where understandings of teaching and learning practices (TaLP) are being discussed in three schools. The questions posed are: what are the relations between thick places, meaning, affect, and TaLP? This study uses an ethnographic method outside the classroom and in between different activities as a starting point for understanding TaLP and where many students at the same school produce thick places of affect and meaning. The main conclusion from this study is that matters of where, what, and who are shaping TaLP. Another important conclusion from this study is that training schools offer new conditions for teacher students, but also offer new opportunities for ethnographic studies that aim at understanding these school environments with a range of new questions.     

《金瓶梅词话》“四季词”的解释与金学中的重大问题

《新刻金瓶梅词话》卷首有四首[行香子]词（有学称之为“四季词”），论曾用这四首[行香子]来论证金学上重要的问题，包括写作时间、写作地点、作的身份等。笔对诸家之说提出质疑，并追溯四首词的真正作和时代，指出四词来源甚早，研究时应区分隐含作（implied author）和历史作。本的结论是四首词的作权并不能拨归《金瓶梅》的作，以前各家基于四首词得出的推论，值得存疑；他们在诠释上的失误，更值得后学警诫。
