做好高职院校新生入馆教育的思考

针对高职院校图书馆存在的对入馆教育不够重视、入馆教育内容太理论化、参观图书馆走过场、读者手册内容简单等问题,阐述开展新生入馆教育的有效途径:重视入馆教育,寻求读者自觉利用图书馆的激情,编发《图书馆使用手册》,以电化教学激发新生兴趣,开设文献检索必修课等。     

Relationship between hyperuricemia and metabolic syndrome

Objective: To investigate the relationship between metabolic syndrome and hyperuricemia. Methods: A total of 2 374 subjects who received health examination in our hospital from Jan. 2004 to Dec. 2006 were enrolled in our study. Hyperuricemia is defined as ≥7 mg/dl (in men) or ≥6.0 mg/dl (in women). Metabolic syndrome was defined using AHA/NHLBI (American Heart Association/National Heart, Lung, and Blood Institute) criteria. Results: (1) The overall prevalence of hyperuricemia was 13.10%. The condition was more common in men than in women (19.07% vs 3.42%). (2) Among men, uric acid concentration is statistically significantly positively correlated with waist circumference, blood pressure, and triglyceride. Uric acid is negatively correlated with serum high-density lipoprotein-cholesterol (HDL-C). Uric acid concentration is most strongly correlated with serum triglyceride (r=0.379) and waist circumference (r=0.297). Among women, statistically significant positive correlations were noted for the serum uric acid concentrations with waist circumference, triglyceride and fasting plasma glucose. Serum triglyceride (r=0.329) and waist circumference (r=0.234) are most strongly correlated with uric acid concentrations. (3) Men with hyperuricemia had a 1.634-fold increased risk of metabolic syndrome as compared with those without hyperuricemia odds ratio (OR)=1.634, P=0.000. Women with hyperuricemia had a 1.626-fold increased risk of metabolic syndrome (OR=1.626, P=0.000) as compared with those without hyperuricemia. Conclusion: Hyperuricemia is prevalent among Chinese population. Additionally, serum uric acid is positively associated with metabolic syndrome.     

逻辑抽象思维与创造性思维--兼谈逻辑抽象思维能力的培养

人类思维的发展历程说明,有创造的出现就有逻辑抽象的出现.而真正的逻辑抽象思维是以概念思维为标志的.创造性想象是概念的联想和思维模式的转换;创造性直觉是逻辑抽象思维基础上的一种思维跳跃.创造性思维中的逻辑抽象表现为一种目的性、收敛性和程序性.培养逻辑抽象思维和提高创造能力要注意将逻辑抽象由经验型向理性型发展,自发型向自控型发展,简单型向辩证型发展.     

以优化环境推进数字经济的健康快速发展

当前我国数字经济的增长势头强劲,在国民经济中的地位显著提升。数字经济的发展依赖于良好的政务环境、营商环境、科创环境,因此地方政府要从软环境和硬环境两个方面优化数字经济发展环境,促进数字经济健康快速发展。     

湖南省永州市中小学学生家长对“体育艺术2+1项目”需求度研究

对永州市中小学学生家长进行问卷调查,结果显示;永州市中小学学生家长文化层次偏低、对"体育、艺术2+1项目"了解程度不高,但非常支持和需要"体育、艺术2+1项目",家长将学校、家庭和社会相结合作为学生接受"体育、艺术2+1项目"的重要手段;家长最想让孩子参加的体育项目是球类项目、艺术项目是绘画类项目。     

美国体育黄金时代“赞美派”与“讽刺派”的新闻写作风格及深远影响

19世纪20年代是美国体育的黄金时代,体育明星、体育记者和营销专家共同缔造了这个时代的辉煌。在这个过程中,体育新闻写作诞生了两种截然不同的流派———“赞美派”与“讽刺派”,他们在主题选择、修辞手法等方面均有鲜明的特点。两个流派不仅在当时推进了美国体育娱乐业的建立和壮大,还发挥着持久的影响力。现在,不论是美国本土,还是中国当下的体育新闻写作均可窥见两种流派的风格遗存。     

人本关怀理念下普通高校体育课程改革探究

在升学与就业的双重压力下,无论学校、教师还是大学生本人都对普通高校体育课程存在不同程度的忽视心理与忽视行为。从体育课程的教学形式、教学内容、教学时长来看,并没有起到促进大学生综合素质提升的作用,也没有对高等教育体系完善做出应有的贡献。而在教学过程中,大学生的个人意愿、学习的主观能动性也没有得到挖掘与激发。可以说,大学体育课程缺乏以人为本的教学理念。这些问题成为大学体育课程亟待改革的弊端。     

论散打运动员的运动智能及训练方法

散打比赛是同场格斗对抗性项目,对运动员的技术、体能、心理、智能都有很高要求.在基层训练中,很多教练过分重视技术和体能的训练,而忽视了对运动员智能的培养和训练.在技术和体能同等的情况下,运动员的心理和智能往往容易左右比赛的胜负.文章运用文献资料法、逻辑分析法对散打运动特点、散打运动智能的构成、运动智能在散打比赛中的重要性、散打运动智能的训练方法进行了论述,希望通过本研究为散打训练提供一定的借鉴,为散打理论的完善起到一定的帮助.     

湖南省中小学“体育艺术2+1项目”体育技能类项目优化研究

基于优化湖南中小学"体育艺术2+1项目"体育技能类项目的目的,运用问卷调查和专家访谈以及不同学段和项群训练理论两种视角,研究发现湖南中小学生可以选择体育舞蹈、篮球、游泳、足球、乒乓球、羽毛球、形体操和跳山羊等项目,可以选择技能主导类表现难美型项群、技战能主导类隔网对抗型项群和技战能主导类同场对抗型项群中的体育项目;同时建议对体育技能类项目的选择和优化要因地制宜,符合地域特色。     

Repeated exercise stress impairs volitional but not magnetically evoked electromechanical delay of the knee flexors

The effects of serial episodes of fatigue and recovery on volitional and magnetically evoked neuromuscular performance of the knee flexors were assessed in 20 female soccer players during: (i) an intervention comprising 4 × 35 s maximal static exercise, and (ii) a control condition. Volitional peak force was impaired progressively (-16% vs. baseline: 235.3 ± 54.7 to 198.1 ± 38.5 N) by the fatiguing exercise and recovered to within -97% of baseline values following 6 min of rest. Evoked peak twitch force was diminished subsequent to the fourth episode of exercise (23.3%: 21.4 ± 13.8 vs. 16.4 ± 14.6 N) and remained impaired at this level throughout the recovery. Impairment of volitional electromechanical delay performance following the first episode of exercise (25.5%: 55.3 ± 11.9 vs. 69.5 ± 24.5 ms) contrasted with concurrent improvement (10.0%: 24.5 ± 4.7 vs. 22.1 ± 5.0 ms) in evoked electromechanical delay (P < 0.05), and this increased disparity between evoked and volitional electromechanical delay remained during subsequent periods of intervention and recovery. The fatiguing exercise provoked substantial impairments to volitional strength and volitional electromechanical delay that showed differential patterns of recovery. However, improved evoked electromechanical delay performance might identify a dormant capability for optimal muscle responses during acute stressful exercise and an improved capacity to maintain dynamic joint stability during critical episodes of loading.
