On the same page in sporting dyads: does dissimilarity on 2 x 2 achievement goal constructs impair relationship functioning?

This study examined the extent to which 2 x 2 achievement goal constructs (Elliot, 1999) were associated with key relational perceptions (i.e., relationship commitment, relationship satisfaction) for members of athlete-athlete dyads. Both members from 82 regional-level partnerships (mean age = 22.72, SD = 3.83) were recruited from a variety of dyadic sports (e.g., tennis, badminton, rowing). Actor-partner interdependence model analyses revealed that greater dissimilarity between partners on mastery-approach and performance-approach goals was associated with lower commitment and satisfaction. Mastery goals displayed positive actor effects with respect to both relationship perceptions, whereas performance-avoidance goals were negatively related to commitment (i.e., actor and partner effects) and satisfaction (i.e., partner effect). These results indicate that achievement goal constructs may align with important interpersonal perceptions in athlete dyads.     

基于协同学的生态工业园不稳定现象的解释与对策

针对生态工业园中出现的不稳定现象,从协同学的涨落、不稳定模、序参量三个角度,具体分析物质链接困难阻碍产业链网络化、生产环境变化触发原料隐性危害、管理模式变动迫使产业链重组这三种不稳定形式,提出了生态工业园经营者需要积累前人经验、全面采取预防和应对措施以避免园区中巨涨落的出现,结点企业任何变动需要从全局考虑、保持园区环境协调统一以抑制新的不稳定模的产生,前后两任管理者需要加强沟通、确保新旧管理模式方向一致以增强新旧序参量的兼容性这三项解决对策。

《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。     

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.

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.
