创业教育在高职教育中占有十分重要的地位。但是,高职院校创业教育的现状并不乐观,存在着认识不到位,教育水平低,组织创业实践活动困难大等问题。我们要采取积极措施,转变思想观念,提高思想认识,建立完整的创业教育体系,加强师资队伍建设,创业教育要做到既注重形式,又注重内容和效果,才能达到创业教育的目的。  相似文献   

基于SRPE竞速运动项目训练负荷评价方法的实证研究     

谢云  耿海峰  李赞 《中国体育科技》2020,(2):30-38

目的:基于自行车运动员的训练负荷实证评价,探讨竞速运动项目训练负荷主观感知疲劳评价(session rating of perceived exertion,SRPE)的有效性,并证明训练因素[心率(HR)、训练压力分数(TSS)、训练刺激量(TRIMP)、代谢当量(MET)、能量消耗(EE)]与非训练因素(自感疲劳、压力等级、睡眠质量、肌肉酸痛、训练积极性)对训练负荷量(SRPETL)的影响作用。方法:10名优秀职业自行车运动员(均为男性),测试开始前1周均未进行过大强度运动。运用SRPE、心率计(Garmin佳明HRM-tri)、码表(Garmin佳明edge 200)、身心恢复测试量表等对42天的高原训练负荷进行测试。内部负荷采用SRPE-TL、ETRIMP、ETRIMP、%HRmax表示,外部负荷采用TSS、MET、EE表示。结果:平均每周的SRPE-TL为5 300±1 512 AU。训练单调性(TM)为2.22±0.81 AU,训练应激(TS)为12 766±1 334 AU。SRPE-TL与各测试指标之间具有显著相关性(r=0.58~0.81)。逐步多元回归分析结果表明ETRIMP、TSS、自感疲劳、肌肉酸痛和压力等级可以解释SRPE-TL 71.8%的变异程度(Y=453.12+2.99 ETRIMP+1.20 TSS-114.81自感疲劳-111.30肌肉酸痛+85.81压力等级)。结论:SRPE是评价竞速项目训练负荷的一种有效手段,并且SRPETL是一个全域性指标,且训练因素与非训练因素均对运动员感知疲劳有影响作用。  相似文献   

Application of network meta-analysis in the field of physical activity and health promotion

Continued advancement in the field of physical activity and health promotion relies heavily on the synthesis of rigorous scientific evidence. As such, systematic reviews and meta-analyses of randomized controlled trials have led to a better understanding of which intervention strategies are superior (i.e., produce the greatest effects) in physical activity-based health behavior change interventions. Indeed, standard meta-analytic approaches have allowed researchers in the field to synthesize relevant experimental evidence using pairwise procedures that produce reliable estimates of the homogeneity, magnitude, and potential biases in the observed effects. However, pairwise meta-analytic procedures are only capable to discerning differences in effects between a select intervention strategy and a select comparison or control condition. In order to maximize the impact of physical activity interventions on health-related outcomes, it is necessary to establish evidence concerning the comparative efficacy of all relevant physical activity intervention strategies. The development of network meta-analysis (NMA)—most commonly used in medical-based clinical trials—has allowed for the quantification of indirect comparisons, even in the absence of direct, head-to-head trials. Thus, it stands to reason that NMA can be applied in physical activity and health promotion research to identify the best intervention strategies. Given that this analysis technique is novel and largely unexplored in the field of physical activity and health promotion, care must be taken in its application to ensure reliable estimates and discernment of the effect sizes among interventions. Therefore, the purpose of this review is to comment on the potential application and importance of NMA in the field of physical activity and health promotion, describe how to properly and effectively apply this technique, and suggest important considerations for its appropriate application in this field. In this paper, overviews of the foundations of NMA and commonly used approaches for conducting NMA are provided, followed by assumptions related to NMA, opportunities and challenges in NMA, and a step-by-step example of developing and conducting an NMA.  相似文献

FDI、产业集聚与全要素生产率增长—基于制造业行业的实证分析   总被引：2，自引：0，他引：2       下载免费PDF全文

张公嵬  陈翔  李赞 《科研管理》2013,34(9):114-122

我国的FDI与产业集聚在空间上的耦合决定了将二者割裂开来研究其对制造业行业TFP增长的影响有失偏颇。本文运用DEA-Malmpuist指数法测算了2000-2009年我国制造业28个行业的全要素生产率(TFP),并将FDI、产业集聚与TFP放在一个统一的框架下分析FDI与产业集聚对制造业TFP及其分解指标的影响。研究发现,制造业TFP年均增长9.6%,其中80%以上是技术进步贡献的;行业间的技术进步差距较小,技术效率变化差异较大,而后者是TFP增长差异的主要其原因。回归结果显示,总体上,FDI存在技术溢出效应,产业集聚发挥了正的外部效应,二者的交互作用对按要素密集度分类的四类型行业TFP增长的影响具有显著差异。  相似文献

Self-efficacy and outcome expectancy in beginning weight training class: their relations to students' behavioral intention and actual behavior     

Gao Z  Xiang P  Lee AM  Harrison L 《Research quarterly for exercise and sport》2008,79(1):92-100

This study was an initial attempt to investigate the relationships among self-efficacy, outcome expectancy, behavioral intention, and actual behavior over time in a beginning weight training class. A total of 109 participants completed questionnaires assessing their self-efficacy, outcome expectancy, and intentions for future weight training. Their attendance and workout logs were calculated as a measure of actual behavior. Correlation analyses revealed significant positive relationships among all the variables during both program periods. Multiple regression analyses indicated that outcome expectancy initially played a more important role than self-efficacy in predicting behavioral intention and actual behavior. However, self-efficacy appeared more influential at midprogram. Findings of this study can enhance our understanding of the determining factors for individuals' motivated behaviors in college physical activity classes.  相似文献
