西安方言轻声的语音图谱探析

普通话中的轻声是一种变调情况。它由于读得轻而短,所以就失去了原先的调子。语音学家研究得出普通话中的轻声由于前面字的声调不同,后边轻声的音高也有所区别。从西安方言具体的语音图谱中观察分析得出:普通话四声后的轻声在西安方言中音高也有所区别,大概排列的顺序为:阳平(35-24)——高;阴平(55-21)——中;去声(51-55)——半低;上声(214-53)——低。

农村幼儿园户外游戏活动的现状与对策研究

<正>《幼儿园教育指导纲要》明确指出,教师要“以多种有趣的体育活动,特别是户外和大自然中的活动来吸引幼儿,培养幼儿积极参加体育锻炼的积极性,并提高其对环境的适应能力”。幼儿园是幼儿最早接受集体教育和参与集体活动的重要场所,幼儿园教育对幼儿的健康成长发挥着重要作用。特别是幼儿园户外活动可培养幼儿的交际能力和语言表达能力,增强幼儿的体质,丰富幼儿的认知,发展幼儿的综合素养。农村幼儿园地处农村,这为幼儿户外活动提供了广阔的空间,     

The influence of achievement motivation and chess-specific motivation on deliberate practice

Although the importance of high motivation to engage in deliberate practice has been acknowledged, no research has directly tested this hypothesis. Therefore, the present study examined this relation in adolescent elite chess players by means of a questionnaire. In addition, to provide an explanation for dropout among promising chess players, differences in motivation between persistent and dropout chess players were analyzed. Competitiveness and the will to excel proved to be predictors of investments in deliberate practice. Moreover, achievement motivation and chess-specific motivation differed to a certain extent between persisters and dropouts. Our results suggest that motivation to engage in deliberate practice not only contains elements of the will to improve performance, but also of the will to attain exceptional levels of performance.     

探析小学数学深度学习策略

随着新课程改革的步骤在不断加快,国家也越来越重视对学生学习素养的培养,小学数学的教学方式也应朝着多元化的方向前进,这对我们小学数学老师的课堂教学的要求又提出新的标准。特别是在新的课程改革推动的浪潮下,学生核心素养的培养成为了当下教育的热门关切点,教师们应当顺应新课改的要求,充分利用政策优势和技术手段,将小学数学教学相融合,创建更加充满创作力、有趣味性的课程学习氛围,充分调动学生们学习数学的积极性和热情,提升学习水平。小学数学老师不仅要注重对学生数学素养能力的培养,同时还要教会学生更多的方法和思路,培养学生的数学核心素养能力。

Epidemiology of insertional and midportion Achilles tendinopathy in runners:A prospective cohort study

Background:Achilles tendinopathy(AT) is a common problem among runners.There is only limited evidence for risk factors for AT,and most studies have not defined the AT subcategories.No study has compared the incidence and risk factors between insertional AT and midportion AT,though they are considered distinct.This study aimed to assess incidence and risk factors of AT based on data from a large prospective cohort.The secondary aim was to explore differences in risk factors between insertional an...

Purpose:This meta-analytical study aimed to explore the effects of resistance training(RT) volume on body adiposity,metabolic risk,and inflammation in postmenopausal and older females.Methods:A systematic search was performed for randomized controlled trials in PubMed,Scopus,Web of Science,and SciELO.Randomized controlled trials with postmenopausal and older females that compared RT effects on body adiposity,metabolic risk,and inflammation with a control group(CG) were included.Independent revie...     

Does eccentric exercise stimulate sarcomerogenesis?

Eccentric exercise has been associated with an increase in serial sarcomere number in some studies,1 but not in others.2 Similarly,increasing excursion of muscles resulted in sarcomerogenesis in some studies using growing animals,3 but not in others using skeletally mature animals.4 However,chronic elongation and chronic shortening appears to be a strong regulator of sarcomere number increase5,6 and decrease,5,7 respectively,in animal models.Despite an abundance of research on the regulation of sarcomerogenesis under a variety of conditions,the mechanisms underlying in series sarcomere number adaptations in skeletal muscles remain a puzzle,especially in non-invasive human studies where measurements of sarcomerogenesis following interventions have not been possible to date.
