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.

再就业培训--成人教育的新市场

当前，随着我国国有企业改革的深化和产业结构调整力度的加大，职工的下岗和再就业问题成为日益突出的社会问题。为了解决这一问题，主要从以下四个方面来论述：更新观念，抓住机遇，寻找成人教育新市场；加快改革，调整教育结构，促进新市场的发展；更新培训内容，适应新的市场要求；终身教育，促进成人教育市场与再就业工程的长期协调发展。     

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。

金圣叹的小说结构技巧论初探

金圣叹在评点《水浒传》时，着力探讨了长篇小说的结构技巧。首先，小说结构应是一个有机的整体；其次，小说结构应具有形式美。我们对此进行了较详细的探讨，这对建构具有民族特色的小说美学，对当今的长篇小说创作都是十分有益的。     

试论歌唱艺术的再创作

音乐是一门表演艺术。在音乐表演中将作曲家的创作称为第一次创作，而表演者的表演则称作再创作。对于声乐演唱而言，具有高超的演唱技巧与技术是进行再创作的重要前提。只有二者共同存在着完美融合，才会产生令人心动的音乐，两者缺一不可。     

从学生就职谈能力培养的内容

从学生的就业市场分析中，我们认为，学生在大学期间应培养以下六种能力：一，适应社会能力；二，组织管理能力；三，学表达能力；四，人际交往能力，五，开拓创新能力；六，决策能力。

Beyond educational attainment: The importance of skills and lifelong learning for social outcomes. Evidence for Europe from PIAAC

Empirical evidence suggests that educational attainment nurtures people's social outcomes and promotes active participation in society and stability. However, it is unclear to what extent other types of human capital also correlate with social outcomes. Hence, we explored the opportunity offered by the PIAAC survey through its provision of information on educational attainment, observed individual key skills proficiency, and participation in adult education and training (adult lifelong learning). We therefore studied the association between these human capital variables and social outcomes, and more specifically interpersonal trust and participation in volunteering activities. Results revealed that these social outcomes were affected not only by the formal qualification obtained, determined by the education variable, but also throughout the life‐cycle. Indeed, education and training when undertaken during adult life have a significant impact, especially on volunteering. The fact that the skill proficiency also plays a significant role is extremely relevant, as skills are more likely to change over the life‐cycle, either in a positive or negative way. Whilst the formal education received is constant after exiting the educational system, skills reflect competences more accurately: first, because those with the same level of education may have different skill levels because of differences in the quality of education or ability; second, because skills can vary over time. For example, they may increase with work experience or informal education, or decrease as a result of depreciation and ageing. These findings suggest that social outcomes are prone to be affected by many factors other than formal education, suggesting that policy makers can implement recommendations even after formal education has been completed.
