大学自由教育的生成逻辑与实践路径探析

自由教育时常被冠以自由主义教育的标签,但其精神实质与当前我国倡导的“学生发展核心素养”教育异曲同工,应该得以澄清。自由教育在国家层面上与社会主义本质及核心价值观的全面发展一致,在社会层面上与科教强国的创新驱动一致,在个人层面上与人才培养的人文关怀一致。因此,高校应该把自由教育与人才培养相结合、把自由教育与创新教育相结合、把自由教育与个人成长相结合。

我国艺术立法原则和研究要点思考

艺术法不是一部单行法规，而是相关法规的总称。由于艺术的外延很大，其所涉及的社会关系也是多种多样，而不仅仅是有关版权的问题，因此，有必要从宏观上把握艺术发生过程中所涉及的一些重要关系。     

The influence of heterogeneous exposure and pre-deliberation queries on pretrial publicity effects

Prior research on pretrial publicity has produced mixed results and a roughly equal number of studies show an effect, show no effect, or show mixed results. We explored the effects of (a) homogenous vs. heterogeneous exposure (whether deliberating jurors were all exposed to the same publicity or not) and (b) pre-deliberation queries as potential contributors to mixed results. We found an effect for positive but not negative publicity on conviction rates but not evidence ratings. Exposure heterogeneity appears to explain these differences and pre-deliberation queries did appear to play some role in the obtained outcomes. Overall these findings do not replicate a robust publicity effect and future research should consider how homogeneous exposure and pre-deliberation opinion queries influence results.

Neuromuscular and technical abilities related to age in water-polo players

Testing is one of the important tasks in any multi-step sport programme. In most ball games, coaches assess motor, physical and technical skills on a regular basis in early stages of talent identification in order to further athletes’ development. The purpose of the study was to investigate anthropometric variables and vertical jump heights as a free throw effectiveness predictor in water-polo players of different age groups. Two hundred and thirty-six young (10–18 years) male water-polo players partitioned into three age groups underwent anthropometric variables’ measures and squat- and countermovement-jump tests, and performed water-polo free throws. Anthropometric variables, vertical jump heights and throw speed – as a proxy for free throw effectiveness – resulted different over age groups. Particularly, throw speed changed from 9.28 to 13.70 m · s^?1 (+48%) from younger to older players. A multiple-regression model indicated that body height, squat-jump height and throw time together explain 52% of variance of throw speed. In conclusion, tall height, high lower limb power and throwing quickness appeared to be relevant determinants for effective free throws. Such indications can help coaches during talent identification and development processes, even by means of novel training strategies. Further research is needed over different maturity statuses.     

A topography of free kicks in soccer

ABSTRACT

This study investigates the spatial relationship of performance variables for soccer free kicks. In order to suggest ways in which players might optimise their performance, we collected data from free kicks (<35 m to goal line) of two German Bundesliga seasons (2013/14, 2014/15) (n = 1624). In the analysis, we applied the ISO-map approach using colour gradients to visualise the mean values of a variable on a 2D-map of the pitch. Additionally, variograms were used to describe the degree of spatial dependence of the free kick variables. Results show that DENSITY, TYPE OF PLAY, PLAYERS IN WALL, DISTANCE TO WALL and RULE VIOLATION were strongly spatially dependent. Centrality and proximity to the goal increased the variables PLAYERS IN WALL, RULE VIOLATIONS and INTERRUPTION TIME, and the ratio of goals scored increased from 5.9% (central far) to 10.9% (central near). In 70.9% of the shots, players preferred a switched laterality, which did not result in a higher success rate. Furthermore, there was no statistical advantage for the defensive team when DISTANCE TO WALL was below 9.15 m or when there was a RULE VIOLATION. Crosses had a success rate (i.e., first controlled ball contact after the cross) of 20.8%. Played with natural laterality, they were 5% more successful than with switched laterality. Crosses from the right side outside the penalty box were 10% more successful than from the left side. Therefore, it might be worthwhile practising the defence of balls coming from this side.     

八段锦竞赛功法对大学生机体自由基代谢和身体形态影响的研究

目的:探索健身气功·八段锦(竞赛功法)对大学生机体自由基代谢和身体形态的影响。方法:主要采用实验法,随机抽取2014级康保系男生和女生各20人,持续进行4个月的功法习练,观察血脂和生理机能的变化。结果:大学生经过4个月的功法习练后,3个时间点测试SOD、CAT和大腿围指标呈上升趋势,MDA、XOD和腰臀比指标呈下降趋势,差异具有统计学意义;测试体重、体重指数和大臂围3项指标没有显著性差异。结论:健身气功·八段锦(竞赛功法)对大学生机体脏腑、固肾壮腰、提振精神、防治疲劳、改善血液循环、提高腰腹柔韧和腿部力量等方面有重要帮助。
