高校外聘人员有效激励管理方式研究     

周培根 《科教文汇》2020,(6):10-11

随着我国社会经济的快速发展,以多元化教育为代表的行业发展理念正在逐步地形成,各种不同规模、不同办学形式的高校开始尝试引入外聘人员,并结合高校自身的实际情况,采取固定编制人员与外聘人员相结合的管理模式,然而外聘人员数量的不断扩大虽然为我国高校增强了师资力量,但同时也在一定程度上增加了外聘人员的管理难度。本文针对高校外聘人员有效激励管理方式开展深入的探究。  相似文献   

Efficacy of using non-linear pedagogy to support attacking players’ individual learning objectives in elite-youth football: A randomised cross-over trial

ABSTRACT

The present study examined the efficacy of a coaching curriculum, based on non-linear pedagogy, on improving attacking players’ individual learning objectives (ILOs) in elite-youth football. Participants included 22 attacking players (i.e., centre-forwards, wide-players and attacking midfield players) from a professional football academy in England. The players were randomly appointed to both control (CON) and intervention (INT) periods following baseline measures. The INT (non-linear) and CON (linear) periods were both designed to support the ILOs provided to each player as part of the elite player performance plan. The study adopted a randomised cross-over design and ILOs considered important for attacking players (i.e., strong foot finishing, weak foot finishing, 1-v-1 and decision-making) were evaluated using the Loughborough Shooting Skill Test. The results showed significant differences for INT in 1-v-1 (P< 0.02) and decision-making (P< 0.01). However, there were no significant differences for strong foot finishing, weak foot finishing or time taken. These results support non-linear pedagogy in developing 1-v-1 game play and decision-making but not for technical shooting proficiency.  相似文献   

Individual and cultural factors in teachers’ attitudes towards inclusion: A meta-analysis     

《Teaching and Teacher Education》2020

The success of inclusive education is dependent upon classroom teachers implementing adaptations for children with disabilities. Given that willingness to make such adaptations is influenced by teacher attitudes, the current study examined teachers’ attitudes towards inclusive education through a meta-analysis of 64 samples that were found via a systematic literature search. The results indicated that teachers hold a positive attitude towards inclusion of children with disabilities in mainstream schools and that these attitudes are moderated by an interplay of cultural and demographical factors. The findings offer a renewed basis for intervention research into improving educational opportunities for children around the world.  相似文献   

视力康复背景下体育锻炼与儿童动态视力关系研究及启示          下载免费PDF全文

潘景玲  蔡赓  殷荣宾  孙雷  王国祥 《体育科研》2019,(1):90-95

目的：探讨动态视力在不同类型体育项目间的发展特征，为体育锻炼改善视力的应用研究提供依据。方法：选取6~10岁无专门体育训练经历的在校学生和参加足球、乒乓球、跆拳道、空手道、游泳、体操等项目的俱乐部或体校学生，共603名。使用动态视力检测仪和标准对数视力灯箱测量动态视力和静态视力。计算动静比（动态视力/静态视力），并将其作为衡量动态视力发展水平的指标。结果：6~7岁是动态视力发展的敏感期（P＜0.05），8岁、10岁男性儿童的动静比高于女性儿童，且差异有统计学意义（P＜0.05）。校外体育练习组的动静比高于普通在校学生组（P＜0.05），开放性运动项目的动静比高于闭锁性运动项目（P＜0.05）。结论：参加体育锻炼对动态视力的发展有积极的影响，且不同运动项目的影响效果不同。  相似文献   

Acute effects of different warm-up protocols on highly skilled golfers’ drive performance     

Ben L. Langdown  Jack E.T. Wells  Sean Graham  Matt W. Bridge 《Journal of sports sciences》2019,37(6):656-664

Previous research has highlighted the positive effect that different warm-up protocols have on golf performance (e.g. Sorbie et al., 2016; Tilley & Macfarlane, 2012) with the design of warm-ups and programmes targeting and improving golf performance through the activation and development of specific muscle groups. This study aimed to examine the acute effects of two warm-up protocols on golf drive performance in comparison to a control condition. Using a randomised counterbalanced design over three testing sessions, twenty-three highly skilled golfers completed the control, dynamic and resistance-band warm-up conditions. Following each condition, a GC2 launch monitor was used to record ball velocity and other launch parameters of ten shots hit with the participants’ own driver. A repeated-measures ANOVA found significant increases in ball velocity (η_p² = .217) between the control and both the dynamic and resistance-band warm-up conditions but no difference between these latter two, and a reduction in launch angle between control and dynamic conditions. The use of either a dynamic stretching or resistance-band warm-up can have acute benefits on ball velocity but golfers should liaise with a PGA Professional golf coach to effectively integrate this into their golf driving performance.  相似文献   

Examining the influence of grip type on wrist and club head kinematics during the golf swing: Benefits of a local co-ordinate system     

Howie J. Carson  Jim Richards  Bruno Mazuquin 《European Journal of Sport Science》2019,19(3):327-335

Wrist movements have been identified as an important factor in producing a successful golf swing, with their complex motion influencing both club head velocity and orientation. However, a detailed analysis of wrist angles is lacking in the literature. The purpose of this study was to determine kinematics across wrists and club head characteristics during the golf swing under weak, neutral and strong grip conditions. Twelve professional male golfers executed 24 shots using a driver under three grip conditions. A six degrees of freedom analysis of the hand with respect to the distal forearm was performed using a 10-camera three-dimensional motion capture system. Differences in joint angles were explored using repeated measures ANOVAs at key swing events (onset, top of backswing and impact), in addition club head velocity and clubface angle at impact were also explored. Main findings revealed significant differences in flexion/extension and internal/external rotation for both wrists at all swing events, whereas fewer significant interactions were found in ulnar/radial deviation across grips for both wrists at all events. Clubface angle only differed significantly between the weak and the strong and neural grips, presenting a more ‘open’ clubface to the intended hitting direction. This study is the first to explore tri-planar wrist movement and the effect of different grips, such analysis has implications for coaching knowledge and practice and should inform future research into different aspects of skill, technique analysis and may inform injury mechanisms/prevention.  相似文献

基于动态分阶势场法的船舶自动避碰系统     

罗贤程  尹建川  李宏宾 《上海海事大学学报》2020,41(1):1-7

为使船舶在多船避让环境下适应航行环境的变化并自动复航,提出基于动态分阶势场法的船舶自动避碰系统。该系统基于动态势场避障规划算法,利用模糊综合评价法量化船舶碰撞危险度;依据《国际海上避碰规则》确定本船在不同会遇局面下的避让行动,并据此对斥力势函数进行调整。该系统将本船的避碰过程划分为航迹保持、避让和复航3个阶段,根据不同阶段的要求构建动态分阶势场;利用动态分阶势场法对船舶的航行环境进行建模,进而生成恰当的航向指令;利用自动舵产生舵角指令控制船舶完成避让、复航和航迹保持。仿真结果表明:该自动避碰系统可以引导船舶完成既定的避让行动,并能使船舶在安全会遇距离上驶过;该系统可以适应航行环境的变化,且具备航迹保持能力。  相似文献
