浅析颜色词的实用效应

颜色词在人们的日常生活中起到至关重要的作用,因而早期就在中国和西方国家受到了关注。然而以前关注的多是中西方文化中颜色词的差异,本文从另一个角度来讨论颜色词的实用效应,这也是近年来,西方国家对颜色词研究的一个趋势。本文基于以下三个方面来展开讨论：（1）颜色词的命名;（2）颜色词的实用效应;（3）影响基本颜色词感知的因素。本文旨在从认知的角度让读者对颜色词有个更为深刻的理解。     

超等长练习对提高运动员弹跳力效果的生物力学研究

跳深练习作为一种提高弹跳力的方法被田径以及其他项目广泛采用,但在最佳跳深高度、跳深形式和负荷等方面存在着一定争议,因此,本文采用问卷调查、实验对比及数理统计等方法探讨跳深练习对提高弹跳力的影响效果,同时研究跳深练习与连续跳跃练习对提运动员弹跳力效果的优劣。结果显示:跳深练习在缩短男运动员起跳时间上优于连续跳跃练习;其他方面跳深练习都不优于连续跳跃练习效果。本文为提高运动员弹跳力训练效果练习手段的选择提供理论依据。     

英国体育文化创意业发展及对中国体育产业的启示

摘要：以英国体育文化创意业作为研究对象。通过文献研究法,收集相关权威经济数据,以英国创意产业的“三分法”对体育文化创意业的概念进行厘清和辨识;运用产业经济学中主导产业扩散效应理论,采用综合分析法进行实证研究,分别从该产业发展对周边相关行业所产生3种扩散效应——前向效应、旁侧效应、后向效应,通过3种扩散效应的组合,获得新的生产函数,使各个产业间的融合化发展趋势不断地走向深化,并不断推进英国体育产业结构的优化和国民经济的快速协调增长,全面论述英国体育文化创意业近20年来飞速发展对该国体育产业乃至其国民经济发展中所起的积极驱动作用;指出体育文化创意业将成为未来体育产业新的经济增长点、新的发展路径、产业结构优化升级的新动力;研究结果为正处于新一轮世界经济结构调整周期中的我国体育产业科学发展和转型升级提供借鉴与指引。

When the crowd evaluates soccer players’ market values: Accuracy and evaluation attributes of an online community

Evaluating the value of athletes to determine whether they should be transferred from one club to another has become a major challenge for managers of sports teams. In the context of German soccer, aficionados have built a large online community that evaluates professional soccer players’ market values. The community has become the main source for reporting market values in the media and has a strong impact on sports economy: it is used in real market transactions and wage negotiations, indicating the power of crowd wisdom in the sports management context.This research describes the evaluation process of the community, investigates the accuracy of its estimated market values, and shows which attributes are most important for market-value evaluations. After demonstrating that the community's market-value estimates can predict actual transfer fees, we show that community evaluations can largely be explained by an econometric model that contains two blocks of determinants: variables that are directly related to players’ talent and variables that result from judgments by external sources (e.g., journalists). Reorganizing variables that were used in previous studies into two blocks (talent vs. external determinants) provides a more differentiated look at the popularity of players than recent literature on the “superstar phenomenon.”     

Labor market conditions and college graduation: Evidence from Brazil

College students graduating in a recession have been shown to face large and persistent negative effects on their earnings, health, and other outcomes. This paper investigates whether students delay graduation to avoid these effects. Using data on the universe of students in higher education in Brazil and leveraging variation in labor market conditions across time, space, and chosen majors, the paper finds that students in public institutions delay graduation to avoid entering depressed labor markets. A typical recession causes the on-time graduation rate to fall by 6.5% in public universities and there is no effect on private institutions. The induced delaying increases average graduation by 0.11 semesters, consistent with 1 out of 18 students delaying graduation by one year in public universities. The delaying effect is larger for students with higher scores, in higher-earnings majors, and from more advantaged backgrounds. This has important implications for the distributional impact of recessions.     

一般选择效果功能理论的困境及其解决

为了实现选择功能对发育功能现象的解释,参照选择功能的解释策略,一般选择效果功能理论认为凡是能产生差别繁殖特征或差别维系特征的选择过程都能赋予生物性状功能。上述两个特征分别由进化时间范畴和发育时间范畴决定,意指同一生物种群中的一些实体因其自身特点比其他实体具有更高的繁殖/生存可能性。其中,差别维系特征既是该理论的创新点,也是其非历史解释困境的来源。对此,文章的解决方案如下:依托于布沙德的生物功能多元论,消解困境。参照沃尔什的关系性生物功能理论,转向更简洁的新关系性生物功能理论。     

高校文化资本对区域经济发展的影响研究

高校作为高等教育的重要载体,是高素质人才的聚集地,其文化资本水平会直接影响教育质量,关系到教育对经济社会发展的贡献程度。文章基于文化资本理论,构建衡量省域内高校文化资本的指标评价体系,运用我国30个省份2009-2018年面板数据计算其存量并采用空间杜宾模型将高校文化资本对区域经济的影响进行实证研究。结果表明:我国高校文化资本存量呈逐年上升趋势,省域间文化资本存在不平衡现象;高校文化资本对区域经济发展存在正向直接效应和间接效应,其不仅能够推动本地区经济发展,还能通过空间溢出效应推动相邻地区经济发展。

Explaining Internet Connectivity

This article provides a framework by which rival firms' incentives for interconnection in unregulated telecommunications markets may be analyzed and argues that the widespread voluntary interconnection observed among Internet service providers (ISPs) is anomalous when compared with examples of other similar markets from U.S. industrial history. However, the fact that it is anomalous provides an opportunity to test common explanations and to explore new explanations for the remarkable connectivity observed among ISPs through a comparative analysis. The comparative analysis reveals that (1) network effects and competitive forces in telecommunications markets will not necessarily drive firms to interconnect their networks voluntarily as there are other options to them, and (2) government actions played an important role in shaping the interconnection behavior competing firms in telecommunications markets. The article then explores some of the implications of these findings for telecommunications policy, and interconnection regulation in particular.
