基于数据融合的自来水浊度检测方法

为了提高流动电流仪(SCM)对自来水浊度检测的精度,文章提出了一种基于神经网络数据融合技术的数据处理方法。该方法可以消除测量中的原水流量、供电电源波动、絮凝剂浓度、温度等干扰量对流动电流仪的影响,提高了测量的精度。     

团队合作中的利益分配机制及其调整过程探讨

本文主要探讨团队合作这种新兴工作机制的利益分配机制,首先提出了两种方法:其一,权的最小平方法,建立在专家评分基础之上,具有一定的主观性;其二,在合作博弈框架之上运用Shapley定理确定分配方案,具有较好的客观性、公正性。本文后一部分主要讨论在使用Shapley定理确定分配方案之后的团队博弈,即一旦团队由合作博弈进入非合作博弈后,团队利益分配是如何进行调整的,以及调整过程中博弈双方的策略变化和这种调整产生的内在机理。

The relationship between major-league sports’ official sponsorship announcements and the stock prices of sponsoring firms

This study presents analysis of the impact of “official product” sports sponsorships with the National Football League (NFL), Major League Baseball (MLB), the National Hockey League (NHL), the National Basketball Association (NBA), and the Professional Golfers Association (PGA) on the stock prices of sponsoring firms. The primary finding of the study is that, in the main, announcements were accompanied by increases in shareholder wealth. The 53 sponsors analyzed experienced mean increases in stock valuations of about $257 million. A multiple regression analysis of firm-specific stock price changes and selected corporate and sponsorship attributes indicates that official product sponsorships with the NBA, NHL, and PGA and those with smaller market shares were associated with the largest gains in share prices. Although corporate cashflow (a proxy for agency conflicts) is statistically unrelated to shareholder approval, sponsorships by high-technology companies were associated with stronger stock price reactions than otherwise. Finally, product congruence with the sponsored sport was positively related to changes in stock prices. T.
