中国足球超级联赛U23新政何以有效?——基于“足协-俱乐部”的博弈     

花楷  刘晓宇  胡凯  隆丽珊 《武汉体育学院学报》2020,54(8):72-80

中超联赛自2017赛季推出U23新政以来备受争议。在"上有政策下有对策"的非合作博弈下，U23新政如何才能实现政策初衷?该文首次采用不完全信息静态博弈模型分析了U23新政下足协与俱乐部的博弈均衡。研究表明：（1）足协推行新政的最优概率为俱乐部采取积极策略给足协带来的净收益与消极策略带来的净收益之比，实质上取决于俱乐部的遵从度。（2）在缺乏讨价还价权时，俱乐部对新政采取消极应对策略是为了减少净损失。俱乐部积极应对的最优概率为消极应对的净损失占其与积极应对的加成即期收益损失之和的比值，实为两害相权取其轻。为激励俱乐部采取积极策略，应降低俱乐部消极应对策略的净收益或积极应对策略的加成即期收益。（3）提高U23新政有效性的治标之策是减少U23政策对中下游球队的冲击，实行有差别的U23政策；对U23球员上场时间低于均值的俱乐部，实行等额或超额递减分成机制。治本之策是培育一个可预期、可持续、可盈利的足球市场，俱乐部能够内生出建立百年基业的长效机制；继续深化足协的去行政化改革，使之向完全社团法人转型。  相似文献

Fair student assessment: A phenomenographic study on teachers’ conceptions     

《Studies in Educational Evaluation》2020

This research focuses on understanding teachers’ conceptions of what constitutes a fair assessment. In recent decades the number of studies seeking to learn about teachers’ conceptions on assessment has multiplied. The idea is simple, and involves the extent to which conceptions have an effect on what happens in practice. With this aim, a phenomenographic study was carried out to understand what is a fair assessment from teachers’ perspectives. Despite the importance of conducting phenomenographic studies in education, in Spain hardly any studies have used this methodology. Participants were 30 teachers at primary/secondary schools in Spain. The results show that teachers' conceptions of fair assessment were divided, some being more closely related to the principle of equality and others to equity. The conclusion of this study highlights the influence of the school context on teachers’ conceptions of what constitutes fair assessment (in the research, there were 15 teachers who worked in schools located in low socioeconomic status contexts and 15 who were in high socioeconomic status environments).  相似文献   

“一带一路”体育赛事交流构想与策略——以英联邦运动会为参照     

王子朴  陈秉信  马家鑫  刘冬磊 《上海体育学院学报》2020,(4):61-69,94

体育是“一带一路”倡议人文交流的重要依托,体育赛事对实现民心相通发挥积极作用。英联邦运动会的长期举办推动了英联邦国家的整体发展,是体育赛事交流的典型案例。通过对英联邦运动会与“一带一路”体育赛事的对比,分析其对“一带一路”体育赛事的借鉴作用,并探讨“一带一路”体育赛事交流的构想与策略。认为:开展“一带一路”体育赛事交流应建立“一带一路”体育组织,组建相应的工作机构,举办“一带一路”国家运动会;构建“多边体育合作机制”,不断扩大“一带一路”体育赛事的覆盖面,重视赛事风险并避免负面影响,鼓励、支持多国举办“一带一路”体育赛事。  相似文献   

Application of velocity loss thresholds during free-weight resistance training: Responses and reproducibility of perceptual,metabolic, and neuromuscular outcomes

ABSTRACT

The aim of this study was to investigate the differences and long-term reliability in perceptual, metabolic, and neuromuscular responses to velocity loss resistance training protocols. Using a repeated, counterbalanced, crossover design, twelve team-sport athletes completed 5-sets of barbell back-squats at a load corresponding to a mean concentric velocity of ~0.70 m·s^?1. On different days, repetitions were performed until a 10%, 20% or 30% velocity loss was attained, with outcome measures collected after each set. Sessions were repeated after four-weeks. There were substantial between-protocol differences in post-set differential ratings of perceived exertion (dRPE, i.e., breathlessness and leg muscles, AU) and blood lactate concentration (B[La], mmol·L^?1), such that 30%>20%>10% by small to large magnitudes. Differences in post-set countermovement jump (CMJ) variables were small for most variables, such that 30%<20%<10%. Standard deviations representing four-week variability of post-set responses to each protocol were: dRPE, 8–11; B[La], 0.8–1.0; CMJ height, 1.6–2.0; CMJ PPO, 1.0–1.8; CMJ PCV, 0.04–0.06; CMJ 100ms-Impulse, 5.7–11.9. Velocity loss thresholds control the magnitude of perceptual, metabolic, and neuromuscular responses to resistance training. For practitioners wanting to reliably prescribe training that can induce a given perceptual, metabolic, or neuromuscular response, it is strongly advised that velocity-based thresholds are implemented.  相似文献   

高校外聘人员有效激励管理方式研究     

周培根 《科教文汇》2020,(6):10-11

随着我国社会经济的快速发展,以多元化教育为代表的行业发展理念正在逐步地形成,各种不同规模、不同办学形式的高校开始尝试引入外聘人员,并结合高校自身的实际情况,采取固定编制人员与外聘人员相结合的管理模式,然而外聘人员数量的不断扩大虽然为我国高校增强了师资力量,但同时也在一定程度上增加了外聘人员的管理难度。本文针对高校外聘人员有效激励管理方式开展深入的探究。  相似文献   

The impact of workplace information literacy on organizational innovation: An empirical study     

《International Journal of Information Management》2020

The present study investigates the relationship between CEO’s information literacy and innovation in small and medium-sized enterprises (SMEs). Even if information literacy’s business value has been recognized in recent literature, its impact on organizational innovation, a critical and strongly information intensive process, has never been studied before. Structural equation modeling based analysis of data collected from 184 company CEOs in Finland revealed that CEOs’ information literacy has a positive impact on the development of exploratory and exploitative innovations in SMEs. Additionally, opportunity recognition mediates the relationship between information literacy and innovation. Overall, the influence of information literacy is slightly stronger on exploitation than exploration. Nevertheless, the mutual positive effect suggests that information literacy enhances innovation ambidexterity in organizations. Based on these findings, we discuss theoretical and practical implications as well as future research opportunities in workplace information literacy research.  相似文献
