生态危机与诗意拯救——《我,雪豹……——献给乔治·夏勒》的生态批评解读     

李梅 《蒙自师范高等专科学校学报》2015,(4):88-90

生态批评是当今世界上一个历久弥新的话题,它就是要"历史的揭示文化是如何影响地球生态的",而彝族诗人吉狄马加的《我,雪豹……——献给乔治.夏勒》就深刻的体现了他浓厚的生态意识,具有超越时代的历史意义。文章试图从生态批评的角度来解读这首诗歌,让诗人强烈的世界意识和生态伦理意识直观的呈现在读者面前,同时也让诗中对生态意识的思考和生态理想得到进一步升华。  相似文献   

Relationship between foot strike pattern,running speed,and footwear condition in recreational distance runners

Compared to competitive runners, recreational runners appear to be more prone to injuries, which have been associated with foot strike patterns. Surprisingly, only few studies had examined the foot strike patterns outside laboratories. Therefore, this study compared the foot strike patterns in recreational runners at outdoor tracks with previously reported data. We also investigated the relationship between foot strike pattern, speed, and footwear in this cohort. Among 434 recreational runners analysed, 89.6% of them landed with rearfoot strike (RFS). Only 6.9 and 3.5% landed with midfoot and forefoot, respectively. A significant shift towards non-RFS was observed in our cohort, when compared with previously reported data. When speed increased by 1 m/s, the odds of having forefoot strike and midfoot strike relative to RFS increased by 2.3 times and 2.6 times, respectively. Runners were 9.2 times more likely to run with a forefoot strike in minimalists compared to regular running shoes, although 70% of runners in minimalists continued to use a RFS. These findings suggest that foot strike pattern may differ across running conditions and runners should consider these factors in order to mitigate potential injury.  相似文献

Thermal mixing of two miscible fluids in a T-shaped microchannel     

Xu B  Wong TN  Nguyen NT  Che Z  Chai JC 《Biomicrofluidics》2010,4(4):44102

In this paper, thermal mixing characteristics of two miscible fluids in a T-shaped microchannel are investigated theoretically, experimentally, and numerically. Thermal mixing processes in a T-shaped microchannel are divided into two zones, consisting of a T-junction and a mixing channel. An analytical two-dimensional model was first built to describe the heat transfer processes in the mixing channel. In the experiments, de-ionized water was employed as the working fluid. Laser induced fluorescence method was used to measure the fluid temperature field in the microchannel. Different combinations of flow rate ratios were studied to investigate the thermal mixing characteristics in the microchannel. At the T-junction, thermal diffusion is found to be dominant in this area due to the striation in the temperature contours. In the mixing channel, heat transfer processes are found to be controlled by thermal diffusion and convection. Measured temperature profiles at the T-junction and mixing channel are compared with analytical model and numerical simulation, respectively.  相似文献

哈尔滨体育学院田径专修班学生皮纹特征的研究     

周洪超  李美 《哈尔滨体育学院学报》2010,28(1):124-126

对哈尔滨体育学院2007级运动系田径专修班学生皮纹进行了采集与分析。结果发现：田径专修班学生的atd角较小;t距比较小;双箕斗明显多,弓型纹较少;大、小鱼际真实花纹明显少。对这些皮纹特征进行统计分析,旨在为运动员选材提供一定参考,从而也为教练员指导教学训练提供辅助作用,同时也促进皮纹学在体育选材中的应用。  相似文献

降低未成年人刑事责任年龄问题的反思     

王艺  胡媚 《连云港职业技术学院学报》2019,(2):43-47

近年来,未成年人刑事犯罪案件时有发生,针对是否降低未成年人刑事责任年龄问题,一直是学界讨论的热点话题。针对这一问题,学界形成的学说主要有降低论、不变论和弹性论,但各个理论都有自己的侧重点,如降低论学说侧重于扩大刑罚的打击范围;不变论则侧重于犯罪的社会预防;弹性论侧重于赋予法官的裁量权去防范该类犯罪。但从刑法的正当性依据、社会责任及我国法律体系一致性的需要角度来看,目前我国仍应保持当前刑事责任年龄不变。  相似文献   

基于在线开放课程的大学英语教学模式在听障全纳学生中的应用     

闵笛  韩梅 《中国轻工教育》2019,(2):88-92

在"互联网+"的时代,在听障全纳专业大学生的大学英语教学过程中引入基于在线开放课程的教学模式具有重要的理论和现实意义。本论文是基于在线开放课程的大学英语教学模式在听障全纳学生中的课堂教学实践。实践表明,引入基于在线开放课程的教学模式后,提高了听障全纳学生学习的主动性,增加了教师的教学密度,使学生可以进行个性化学习,学生英语成绩显著提高,四六级通过率也大幅上升。在线开放课程在听障全纳学生的大学英语教学中的应用初见成效。  相似文献
