沈从文的时间意识     

覃新菊 《信阳师范学院学报(哲学社会科学版)》2006,26(6):1-5

沈从文的时间意识与死亡意识相生相成,构成沈从文“生命哲学”的重要而又特殊的组成部分。他认为时间的魔力巨大,能消融生命,能治疗痛苦,还能造就创作;他的时间意识停留在“过去”,具有“过去式”、“静态化”与“突变性”的特点。  相似文献   

论创新观念的实现机制     

夏莉 《巢湖学院学报》2003,5(2):13-18

实践的辨证本性是创新观念产生发展的动力机制；理性因素和直觉、非理性因素构成了创新观念运行的思维机制；合规律性合目的性是创新观念转化的内在约束机制；而社会的经济条件、政治条件、精神条件则是创新观念实现的外部环境机制。  相似文献   

民族因素与渤海政权的建立     

杨秀祖 《通化师范学院学报》2007,28(6):19-21

在渤海政权建立的过程中,民族因素发挥了不可替代的作用,高句丽文化特别是中原先进文化的强烈影响、契丹贵族发动的营州之乱、黑水靺鞨扩张势头的受挫、后突厥汗国崛起后对辽西走廊交通的控制,为渤海政权的建立创造了有利条件并提供了机会。  相似文献   

影响大学生篮球裁判员临场判罚的因素与对策研究     

王安大川  张健  王厚雷 《湖北体育科技》2016,(3):233-235

主要采用文献资料法、访谈法、观察法,对影响我校篮球裁判临场判罚的因素进行了以下具体的分析认为:在篮球比赛中裁判临场判罚时容易出现的问题是理论知识不熟、临场实践少、基本功不扎实、临场心理因素不稳定、体能欠缺、思想因素等方面有关系,解决问题的关键是加强我校篮球裁判对篮球规则和裁判法的理解,通过不断的实践,逐步提高自身的执裁水平;通过学习理论然后结合实践,不断积累临场经验,通过参执裁不同层次比赛的,在实践中不断增强自身的执裁能力,增强自信心;加强心理素质的培养和身体素质的锻炼。  相似文献   

Inter-participant variability in daily physical activity and sedentary time among male youth sport footballers: independent associations with indicators of adiposity and cardiorespiratory fitness     

Sally A. M. Fenton  Joan L. Duda  Timothy Barrett 《Journal of sports sciences》2016,34(3):239-251

Participation in youth sport is assumed to promote and contribute towards more physically active lifestyles among children and adolescents. The aim of this study was to examine inter-participant variability in objectively measured habitual physical activity (PA) behaviours and sedentary time among youth sport participants and their implications for health. One-hundred-and-eighteen male youth sport footballers (Mean ± s = 11.72 ± 1.60) wore a GT3X accelerometer for 7 days. Average daily PA [min · day^?1, in light (LPA), moderate (MPA), vigorous (VPA) and combined moderate-to-vigorous (MVPA)] and sedentary time were calculated. Participants’ body mass index adjusted for age and sex (BMI–standard deviation score), per cent body fat (BF%), waist circumference and cardiorespiratory fitness were assessed. Results revealed that variability in daily PA behaviours and sedentary time (min · day^?1) was associated with BMI–standard deviation score [VPA (?), MVPA (?)], BF% [sedentary time (+), VPA (?), MVPA (?)], waist circumference [sedentary time (+), LPA (?)] and cardiorespiratory fitness [sedentary time (?), MPA (+), VPA (+), MVPA (+)]. Whilst sedentary time and MVPA were not related to health outcomes independent of one another, associations with markers of adiposity and cardiorespiratory fitness were stronger for sedentary time. Sedentary time was also significantly positively related to waist circumference independent of VPA. Results demonstrate inter-participant variability in habitual PA and sedentary time among youth sport participants which holds implications for their health. Thus, promoting PA and, in particular, reducing sedentary time may contribute towards the prevention of adverse health consequences associated with a physically inactive lifestyle for children and adolescents active in the youth sport context.  相似文献   

Accelerometer data requirements for reliable estimation of habitual physical activity and sedentary time of children during the early years - a worked example following a stepped approach

This study presents a worked example of a stepped process to reliably estimate the habitual physical activity and sedentary time of a sample of young children. A total of 299 children (2.9 ± 0.6 years) were recruited. Outcome variables were daily minutes of total physical activity, sedentary time, moderate to vigorous physical activity and proportional values of each variable. In total, 282 (94%) provided 3 h of accelerometer data on ≥1 day and were included in a 6-step process: Step-1: determine minimum wear-time; Step-2: process 7-day-data; Step-3: determine the inclusion of a weekend day; Step-4: examine day-to-day variability; Step-5: calculate single day intraclass correlation (ICC) (2,1); Step-6: calculate number of days required to reach reliability. Following the process the results were, Step-1: 6 h was estimated as minimum wear-time of a standard day. Step-2: 98 (32%) children had ≥6 h wear on 7 days. Step-3: no differences were found between weekdays and weekend days (P ≥ 0.05). Step-4: no differences were found between day-to-day variability (P ≥ 0.05). Step-5: single day ICC’s (2,1) ranged from 0.48 (total physical activity and sedentary time) to 0.53 (proportion of moderate to vigorous physical activity). Step-6: to reach reliability (ICC = 0.7), 3 days were required for all outcomes. In conclusion following a 7 day wear protocol, ≥6 h on any 3 days was found to have acceptable reliability. The stepped-process offers researchers a method to derive sample-specific wear-time criterion.  相似文献

9.11事件后地缘政治观的反思   总被引：1，自引：0，他引：1  

赵为民 《洛阳师范学院学报》2002,21(6):26-28

地缘政治这一传统观念在经济全球化、政治趋向多极化的背景下,遇到了强有力的挑战。9.11事件后美国政府正在重构其地缘逻辑思维。适时提出“时缘政治”和“人缘政治”概念,全面审视世界政治格局。我国应从国家利益出发,积极重构地缘战略格局。  相似文献
