论武术与小康社会

武术是中华民族传统体育项目，而小康社会是我国社会主义现代化建设中一个重要的历程。本通过对武术与小康社会的关系，武术对全面建设小康社会的作用和社会价值等论述，说明了武术的开展和小康社会的建设具有相互融合，相互促进的功效。     

Rationalising for and against a policy of school-led careers guidance in STEM in the U.K.: a teacher perspective

This paper reports on teacher attitudes to changes in the provision of careers guidance in the U.K., particularly as it relates to Science, Technology, Engineering and Mathematics (STEM). It draws on survey data of n?=?94 secondary-school teachers operating in STEM domains and their attitudes towards a U.K. and devolved policy of internalising careers guidance within schools. The survey presents a mixed message of teachers recognising the significance of their unique position in providing learners with careers guidance yet concern that their ‘relational proximity’ to students and ‘informational distance’ from higher education and STEM industry may produce bias and misinformation that is harmful to their educational and occupational futures.     

浅谈英语口语学习的情感障碍

情感因素对第二语言学习具有极其重要的影响.在听、说、读、写四项技能中,"说"受情感的影响最大.作者认为积极的情感因素可以促进口语的学习过程,提高学习者的学习效果,消极的情感因素则会对口语的学习产生障碍,影响学习者学习潜力的发挥.本文探讨了消极的情感因素,如焦虑,低自尊心,紧张的课堂气氛等对口语学习产生的障碍.在此基础上作者提出了一些相关性的建议.     

高师小教专业学生成绩的影响因素研究

随机抽取陇东学院教育系278名小教专业大学生，进行问卷调查，探究高师小教专业大学生学业成绩的影响因素。研究发现，高师小教专业大学生虽然具有较高的社会支持和学业抱负水平，但对所学专业课程兴趣不浓厚．内在学习动机不强。因此，高师小教专业大学生表现出“高学业抱负水平与低学习行为质量”相矛盾的特点。此外，教师自身以及在教学方面所存在的问题、学生学习方法的不科学性均是高师小教专业大学生学业成绩不良的主要制约因素．     

谈美国实用主义的形成对建设社会主义核心价值体系路径选择的启示

实用主义是"美国精神".美国实用主义的形成,对于我国核心价值体系建设的路径选择所提供的启示是:以民族振兴为路径前提,以人本主义为路径基础,以解放思想为路径依靠,以循序渐进为路径进程.     

FRFT-OFDM系统联合同步算法

研究OFDM系统中的同步问题. 通过对LFM信号在分数阶傅里叶域能量汇聚性的分析,提出一种基于FRFT的具有较低复杂度的联合载波频率、采样频率以及符号定时的同步算法.该算法在分数阶傅里叶域对由插入到OFDM符号中的LFM信号所产生的对称点进行搜索,结合FRFT的时移、相移以及分数阶卷积等性质,对3种偏差进行估计.仿真结果表明,该算法的性能随LFM信号长度的增加而提高,且优于其他同类算法.     

Heart rate prescribed walking training improves cardiorespiratory fitness but not glycaemic control in people with type 2 diabetes

Abstract

In this study, we examined the effects of a supervised, heart rate intensity prescribed walking training programme on cardiorespiratory fitness and glycaemic control in people with type 2 diabetes mellitus. After receiving local ethics approval, 27 individuals (21 males, 6 females) with type 2 diabetes were randomly assigned to an experimental (“walking”) or control group. Participants completed a Balke-Ware test to determine peak heart rate, peak oxygen consumption ([Vdot]O_2peak), and peak gradient. The walking group then completed a 7-week (four sessions a week) supervised, heart rate prescribed walking training programme, whereas the control group continued daily life. After training, participants completed another Balke-Ware test. Fasting blood glucose and glycosylated haemoglobin were measured at rest. The results showed that walking training elicited 80% (s = 2) of peak heart rate and a rating of perceived exertion of 11 (s = 1). Peak heart rate and [Vdot]O_2peak were higher in the walking than in the control group after training (P < 0.05). Based on the peak gradient before training, the respiratory exchange ratio was significantly lower (P < 0.05) and there was a strong trend for [Vdot]O₂ (P = 0.09) and heart rate (P = 0.09) to be lower after training at the same gradient in the walking compared with the control group. These improvements increased walking peak gradient by 5 min (s = 4 min) compared with the control (P < 0.05). There was no change in fasting blood glucose or glycosylated haemoglobin after training. Despite no change in glycaemic control, heart rate prescribed walking improved peak and sub-maximal cardiorespiratory responses. The beneficial adaptations support the use of heart rate monitoring during walking in people with type 2 diabetes mellitus.     

Interactions among Dietary Pattern,Physical Activity and Skinfold Thickness

Abstract

This study was designed to assess the effects of a specifically designed perceptual-motor training program on the level of perceptual-motor development, self-concept, and academic ability of kindergarten children. Subjects for the study were 40 kindergarten children randomly assigned to 1 of 2 groups. Each group received the same kindergarten program with one exception, the experimental group was exposed to a specifically designed perceptual-motor program 30 min daily for 5 mo, while the control group received a free play period for 30 min daily. Results of the study indicated that the data tended to support the specificity of training concept. The variables showing the greatest change were the perceptual-motor tests which measured changes on specific aspects of the training program. There appeared to be some immediate transfer to academic abilities but this was not pronounced enough to suggest that perceptual-motor training was of real benefit in developing academic abilities for normal kindergarten children. In addition the follow-up test indicated no long term effects on academic performance.
