论韦庄词的情感特质

晚唐词人韦庄以直抒胸臆的创作手法和表现视域的宽阔、题材的多样性，直接开启了宋代婉约词的先风。他的歌词再现了自己双重人格和双重情感特质，充溢着对生命短暂的感叹、壮志难酬的忧虑，历尽磨难渴望和平的理性向往，以及扬弃正统思想的等级观念之后，对下层民众深表同情的人主义情结。同时也反映了晚唐及时行乐消沉颓废的时代风尚在他思想和灵魂深处留下的点点痕迹。     

一种基于任意长离散余弦变换的并行递归算法

基于Clenshaw递归公式以及离散余弦自身的对称性提出任意长离散余弦变换(DCT)的一种并行递归快速算法,给出了算法的滤波器实现结构;与现有的其它递归算法进行了计算复杂度的比较分析,结果表明我们的算法运算量大大减少且计算的滤波器结构使算法非常适合大规模集成电路(VLSI)的实现.     

Using a discrete choice experiment to estimate spectators’ willingness to pay for professional baseball park sportscape

The physical environment of sport facilities, referred to as the sportscape, has a substantial influence on the extent to which sport fans attend sporting events and revisit the facilities. Accordingly, professional franchises make efforts to construct new stadiums with different sportscape elements, which serve as important factors that determine spectators’ levels of attendance satisfaction. With a sample of South Korean baseball fans, the authors examine which sportscape components of professional ballparks are considered most important by spectators, as well as how baseball attendees indicate their willingness to pay for particular sportscape attributes. Based on a discrete choice experimental approach, results indicate that spectators place the greatest importance on fast access to ballparks largely dependent upon the location. Results also suggest that respondents are willing to pay KR₩4102 for one more subway line. Different strategies for developing successful sportscape components are discussed.     

Broadway productions and the value of a Tony Award

This article investigates the effect of a Tony nomination or win on the demand facing a Broadway production using a panel of weekly revenues for Broadway productions from 1996 to 2007. Our results indicate that the effect of a nomination or win is positive in the week of the announcement and gradually increases in successive weeks, presumably due to publicity and word-of-mouth. Winners experience an increase in demand as late as 1 year later when awards are publicized for the following season. Moreover, nominees that do not win the award are penalized heavily in the weeks following the Award announcements. We find that winning a Tony Award increases a production’s revenues by 12% in the week immediately following the Awards.

Emotions correlate with perceived mental effort and concentration disruption in adult sport performers

Abstract

Two studies explored the relationship between emotions, perceived mental effort and concentration disruption in adult sport performers. In Study 1, semi-professional association football players completed questionnaire measures before and after a competitive match. In Study 2, student athletes completed questionnaire measures for two performance scenarios: one in which they were performing above their normal level and one in which they were performing below their normal level. Findings demonstrated that cognitive trait anxiety was associated with greater disruptions in concentration but was unrelated to mental effort. For state measures, athletes reported greater levels of concentration disruption when experiencing high levels of anxiety or high levels of happiness, and fewer disruptions in concentration when experiencing high levels of excitement. Findings also showed that excitement was associated with low levels of mental effort during good performances and high levels of mental effort during poor performances; anxiety and happiness were associated with high levels of mental effort during good performances and low levels of mental effort during poor performances. Taken together, these studies point towards potential benefits accompanying high levels of excitement and potential disadvantages accompanying high levels of anxiety and happiness.
