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

Abstract

How does a small community college library, without marketing experience or budget, advocate for its value to a campus community and its administrators? We did so by creating an engaging, bright, and easy-to-read “pocket-graphic.” In this column, we reflect on the process of shaping a multi-use product out of a mountain of data. Through research in design practices, field observations of popular information tools, and an uncomfortable step into braggadocio, we learned to articulate the successes of our library. Our “pocket-graphic” told our story, yes – but it also provoked surprise, questions (“you really have all that?”) and delight in the lesser known successes (“you really DO all that!”). In the process, we connected our students more deeply to helpful services and resources, faculty to supportive instruction, and positively changed the tone of conversation with all our stakeholders. By turning data points into selling points, we found insights and a focus that moved our own development forward, helping ourselves to define improved priorities for advancing our critical role in student success.  相似文献

《Sport Management Review》2020,23(2):315-329
In many countries, voluntary sports clubs are the main recipients of public subsidies regarding the provision of recreational sport, and the economically most important level of government is usually the local government (i.e. the municipalities). The purpose of this article is to examine whether and how municipal framework conditions matter for sports clubs. Inspired by previous studies, we examine the role of direct and indirect public subsidies as well as facility coverage. The authors conduct analyses on a general level (for all sports) and specifically for five sports (badminton, football, gymnastics, handball and swimming). The differentiation between sports allows us to examine how municipal framework conditions might be associated differently with density and participation across sports. In the statistical analyses, the authors apply data collected among all 98 Danish municipalities. The results show that the municipal levels of direct and indirect subsidies are weakly correlated with both the density of and participation in sports clubs, while stronger correlations can be identified with regard to facility coverage. The analyses for the five sports reveal that the supply of relevant facility types is – with few exceptions – positively correlated with sports club density and participation levels within each sport. Thus, facility coverage seems to play a more important role for sports clubs than the levels of indirect and particularly direct subsidies.  相似文献

This article explores the language used to defend reputation in instances of defamation, debt and theft presented before the ecclesiastical courts of the Archbishopric of York in the latter part of the medieval period. Finding a circulating language of trust and household credibility in the court papers, the argument concludes that the commodification of reputation was not a phenomenon brought about by the Reformation but that a reputation mechanism was intrinsic to the medieval market embedded in informal institutions, social norms and cultural dictates and enforced in the courts.  相似文献

ABSTRACT

In highland Papua New Guinea wealth distribution after a windfall is typically concealed by the donor. This trend was made easier by the introduction of state-issued currency, such that wealth reckoning and especially distribution preferences are often shrouded in mystery. The researcher set out to learn how denomination structures those money transfers by employing a semi-structured interview method centered around hypothetical distributions based on everyday encounters. Across four tailored ‘scenarios,’ fifteen Papua New Guinean participants dwelt on who to give money to, why, and under what conditions. Observations are made about the driving forces in distribution practices, the pecuniary conception of certain relationships’ importance, and relationships that turn on local conceptions of how to capitalize on the way money operates, thus demonstrating the utility of a culturally sensitive quantitative methodology.  相似文献

ABSTRACT

This paper proposes a novel approach for understanding money users’ relation to monetary governance institutions. It first describes the stakes involved in monetary governance from a neo-chartalist/MMT perspective. In a second step, it discusses existing contributions on the relation between money issuer and money users, highlighting the literatures on central bank legitimacy and the social construction of money. It argues that neither allows for an analysis of the relation between monetary institutions and money users that takes the latter’s knowledge seriously. It then argues that the concept of moral economy can enrich scholarly analysis. Moral economies of money are defined as collective practices in which money users articulate demands as part of an understanding of money as a public good. Finally, the paper deploys the moral economy of money perspective to reconstruct the changing relation between institutions of monetary governance and money users since the Great Depression in the U.S. It shows how New Dealers silenced a moral economy of money, discusses fragmented moral economies after World War II, and the partial reemergence of such moral economies after the Great Financial Crisis. The paper concludes by discussing political implications and suggestions for further research.  相似文献

Abstract

This study examined a project that delivered social work services to homeless individuals. A mixed-methods case study was conducted using quantitative and qualitative data from 93 library employees and the project’s Homelessness Prevention Outreach Worker (HPOW). There was an increase in the number of clients accessing community supports during the project, and the HPOW was integral to the provision of support and resources to homeless individuals. Staff training was associated with significantly greater knowledge, comfort, and skills in working with homeless individuals. These findings can inform the delivery and implementation of similar programs for homeless individuals.  相似文献
