《西州使程记》中的北宋初期高昌回鹘体育研究——兼论“一带一路”倡议下新疆体育文化的发展启示

《西州使程记》是记录北宋初期高昌回鹘社会文化风貌的重要史料。通过对历史文献和文物古迹的双向考证,对《西州使程记》中记载的体育娱乐活动进行研究,在此基础上提出“一带一路”倡议下新疆体育文化的发展启示。结果表明：《西州使程记中》所记载的体育娱乐活动有骑射、射物禳灾、苏幕遮以及优戏。《西州使程记》中的体育娱乐活动,反映出北宋初期高昌回鹘社会具有一定的经济发展水平、体现多元的文化形态以及深受宗教思想影响等特征。研究《西州使程记》中的北宋初期高昌回鹘体育,得到的启示是：“一带一路”倡议背景下,新疆体育文化的发展应避免宗教的干扰;应加强对外沟通和交流;新疆体育文化应当引起学界的更多关注;新疆体育文化的研究需注重文物保护和宣传工作。     

A comparison of methods to determine bilateral asymmetries in vertical leg stiffness

Whilst the measurement and quantification of vertical leg stiffness (K_vert) asymmetry is of important practical relevance to athletic performance, literature investigating bilateral asymmetry in K_vert is limited. Moreover, how the type of task used to assess K_vert may affect the expression of asymmetry has not been properly determined. Twelve healthy males performed three types of performance tasks on a dual force plate system to determine K_vert asymmetries; the tasks were (a) bilateral hopping, (b) bilateral drop jumping and (c) unilateral drop jumping. Across all the three methods, K_vert was significantly different between compliant and stiff limbs (P < 0.001) with a significant interaction effect between limb and method (P = 0.005). Differences in K_vert between compliant and stiff limbs were ?5.3% (P < 0.001), ?21.8% (P = 0.007) and ?15.1% (P < 0.001) for the bilateral hopping, bilateral drop jumping and unilateral drop jumping methods, respectively. All the three methods were able to detect significant differences between compliant and stiff limbs, and could be used as a diagnostic tool to assess K_vert asymmetry. Drop jumping tasks detected larger K_vert asymmetries than hopping, suggesting that asymmetries may be expressed to a greater extent in acyclic, maximal performance tasks.     

Positional group significantly influences the offensive and defensive skill involvements of junior representative rugby league players during match play

This study examined the skill involvements of three positional groups across a junior representative rugby league season. Data were collected from 45 rugby league players (mean ± SD; age = 16.5 ± 1.0 years) currently participating in the Harold Matthews and SG Ball Cup. Players were subdivided into hit-up forwards, adjustables and outside backs. The frequency (n · min^?1) of offensive, defensive and overall involvements was coded for each group using a notation system and a practical coach skill analysis tool. Multivariate analysis of variance (MANOVA) revealed a significant effect of playing position on skill involvements (F = 9.06; P < 0.001; ES = 0.41). Hit-up forwards performed a significantly greater frequency of offensive (0.31 ± 0.10), defensive (0.42 ± 0.15) and overall involvements (0.74 ± 0.19) when compared to adjustables (0.20 ± 0.08, 0.28 ± 0.08 and 0.52 ± 0.15, respectively) and outside backs (0.20 ± 0.12, 0.11 ± 0.07 and ± 0.31 ± 0.17, respectively). Further, adjustables performed a significantly greater number of defensive (0.28 ± 0.08) and overall involvements (0.52 ± 0.15) when compared to outside backs (0.11 ± 0.07 and 0.31 ± 0.17, respectively). The findings of this study suggest that it is important to consider a junior player’s positional group when analysing their skill involvements. Information gained from this study could assist in the design of specific training methodologies for junior rugby league players in high-level talent development programmes.

College selectivity and young adult health behaviors

Large literatures have shown important links between the quantity of completed education and health outcomes on one hand and the quality or selectivity of schooling on a host of adult outcomes, such as wages, on the other hand. However, little research attempts to produce evidence of the link between school quality and health. The paper presents the first evidence in the literature on the potential short and intermediate term effects of attending a selective college on health behaviors during and following college attendance. Using a variety of empirical methods, this paper shows strong evidence that college selectivity reduces tobacco and marijuana use but has small and possibly positive effects on binge drinking. The effects on weight behaviors are suggestive of reduced weight, potentially through diet, but not exercise change.     

Education recoded: policy mobilities in the international ‘learning to code’ agenda

Abstract

Education policy increasingly takes place across borders and sectors, involving a variety of both human and nonhuman actors. This comparative policy paper traces the ‘policy mobilities,’ ‘fast policy’ processes and distributed ‘policy assemblages’ that have led to the introduction of new computer programming practices into schools and curricula in England, Sweden and Australia. Across the three contexts, government advisors and ministers, venture capital firms, think tanks and philanthropic foundations, non-profit organizations and commercial companies alike have promoted computer programming in schools according to a variety of purposes, aspirations, and commitments. This paper maps and traces the evolution of the organizational networks in each country in order to provide a comparative analysis of computing in schools as an exemplar of accelerated, transnationalizing policy mobility. The analysis demonstrates how computing in schools policy has been assembled through considerable effort to create alignments between diverse actors, the production and circulation of material objects, significant cross-border movement of ideas, people and devices, and the creation of strategic partnerships between government centres and commercial vendors. Computing in schools exemplifies how modern education policy and governance is accomplished through sprawling assemblages of actors, events, materials, money and technologies that move across social, governmental and geographical boundaries.     

Adaptive neural design frame for uncertain stochastic nonlinear non-lower triangular pure-feedback systems with input constraint

This paper dedicates to dealing with the adaptive neural design problem for uncertain stochastic nonlinear systems with non-lower triangular pure-feedback form and input constraint. On the basis of the mean-value theorem, the pure-feedback structure is first transformed into the desired affine structure, and then the well-known backstepping technology is applied to construct the actual input signal of the controller. Although the considered system has a fairly complex structure, a new adaptive neural tracking controller design frame is established via the flexible application of radial basis function (RBF) neural networks’ (NNs’) structural characteristics. The proposed design frame guarantees the control objective of this paper can be achieved. Finally, a simulation example is given to further illustrate the availability of the proposed control scheme.
