The impact of immediate test score reporting on university students' achievement emotions in the context of computer-based multiple-choice exams     

《Learning and Instruction》2017

Test-taking is an emotion-laden event for many students. Typically, negative emotions are highest at the start of an examination and are replaced by positive emotions as the exam progresses. The impact of computer-based testing and immediate score reporting on students' emotions has not been examined. In Study 1, we evaluated university students’ emotions at the end of a computer-based exam and found positive emotions more strongly endorsed than negative. In Study 2, we replicated this finding and used a quasi-experimental pre-post design to examine how emotions changed in response to real examination scores. Exam scores presented immediately had significant positive effects on relief, pride, and hope and negative effects on anxiety and shame even after controlling for the corresponding emotion at the end of the exam. The one exception was anger, which was not impacted by examination score. No interaction effects were found.  相似文献

一种基于任意长离散余弦变换的并行递归算法     

沈宏君 《宁夏师范学院学报》2007,28(6):28-32

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.  相似文献   

小波变换在信号奇异性检测中的应用     

孙成祥  晁勤 《科技广场》2006,(11):11-13

小波变换突破了传统傅里叶变换等信号处理方法的限制,在时域和频域上可同时对信号实现局部化处理,这更符合信号非平稳的变频带结构特征,因而在信号检测奇异性等方面具有广泛的应用价值。本文简要地介绍了小波应用在信号奇异性检测方面变换的基本原理,并通过仿真实验进行了验证。  相似文献   

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

《Sport Management Review》2019,22(4):502-512

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.  相似文献   

Broadway productions and the value of a Tony Award     

Melissa Boyle  Lesley Chiou 《Journal of Cultural Economics》2009,33(1):49-68

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.
