西部大开发战略的经济学思考

西部大开发战略的提出标志着我国经济发展战略的重大转变,也是实现经济均衡发展的重要举措,如何实现西部经济快速起飞,关键在于实现三个转变：经济发展战略从“梯度推移论”到西部跳跃发展;经济发展环境从偏向沿海地区向西部地区转移;经济发展重点从城市偏向改革到注重农村市场开拓。

Mediating effects of resistance training skill competency on health-related fitness and physical activity: the ATLAS cluster randomised controlled trial

The purpose of this study was to examine the mediating effect of resistance training skill competency on percentage of body fat, muscular fitness and physical activity among a sample of adolescent boys participating in a school-based obesity prevention intervention. Participants were 361 adolescent boys taking part in the Active Teen Leaders Avoiding Screen-time (ATLAS) cluster randomised controlled trial: a school-based program targeting the health behaviours of economically disadvantaged adolescent males considered “at-risk” of obesity. Body fat percentage (bioelectrical impedance), muscular fitness (hand grip dynamometry and push-ups), physical activity (accelerometry) and resistance training skill competency were assessed at baseline and post-intervention (i.e., 8 months). Three separate multi-level mediation models were analysed to investigate the potential mediating effects of resistance training skill competency on each of the study outcomes using a product-of-coefficients test. Analyses followed the intention-to-treat principle. The intervention had a significant impact on the resistance training skill competency of the boys, and improvements in skill competency significantly mediated the effect of the intervention on percentage of body fat and the combined muscular fitness score. No significant mediated effects were found for physical activity. Improving resistance training skill competency may be an effective strategy for achieving improvements in body composition and muscular fitness in adolescent boys.     

Dribbling determinants in sub-elite youth soccer players

Dribbling speed in soccer is considered critical to the outcome of the game and can assist in the talent identification process. However, little is known about the biomechanics of this skill. By means of a motion capture system, we aimed to quantitatively investigate the determinants of effective dribbling skill in a group of 10 Under-13 sub-elite players, divided by the median-split technique according to their dribbling test time (faster and slower groups). Foot-ball contacts cadence, centre of mass (CoM), ranges of motion (RoM), velocity and acceleration, as well as stride length, cadence and variability were computed. Hip and knee joint RoMs were also considered. Faster players, as compared to slower players, showed a 30% higher foot-ball cadence (3.0 ± 0.1 vs. 2.3 ± 0.2 contacts · s^?1, P < 0.01); reduced CoM mediolateral (0.91 ± 0.05 vs. 1.14 ± 0.16 m, P < 0.05) and vertical (0.19 ± 0.01 vs. 0.25 ± 0.03 m, P < 0.05) RoMs; higher right stride cadence (+20%, P < 0.05) with lower variability (P < 0.05); reduced hip and knee flexion RoMs (P < 0.05). In conclusion, faster players are able to run with the ball through a shorter path in a more economical way. To effectively develop dribbling skill, coaches are encouraged to design specific practices where high stride frequency and narrow run trajectories are required.

高职市场营销专业职业技能培养的思考

高职市场营销专业职业技能培养目标应体现出实用性，职业技能教学要突出训练性，职业技能考核要体现开放性，这样才能更好地体现出高职的教育特色，有利于学生职业技能的形成。     

言语技能的掌握与外语基本能力的培养

掌握外语不仅要掌握关于外语的知识,重要是熟练运用外语的各种言语技能。外语的各种技能之间有着不同程度的依存关系,或相互影响,或相互补充,对一种技能的掌握有利于另一种技能的发展。从学习者的心理特点上看,掌握外语言语技能可以分为三个层级。提高外语教学质量的关键就在于如何有效地推动和加速三个掌握层级上的发展和变化,而加速三个掌握层级的发展变化的基本途径就是要培养学习者的基本外语能力。
