李斯特交响诗《匈奴之战》中的音乐叙事模式探究

李斯特不仅在交响诗中创造出“音乐文学化”的叙事模式,即借助戏剧、诗歌等文学题材来结构音乐,还借助绘画题材开辟出一条“音乐图像叙事”路径,其第十一首交响诗《匈奴之战》即为实践范例。从音乐叙事理论视角来看,作曲家在构建与绘画形象、色彩相一致的音乐主题动机基础上,具体通过主题变形、技法处理、结构布局、音色组合等技术形式,来营造绘画颜色与音色色彩之间的通感效果,从而达到音乐材料与标题文本的契合。     

Structure of fractional spaces generated by second order difference operators

A second order difference operator with nonlocal boundary conditions is considered. The positivity of this operator in Banach spaces is proved. Moreover, the structure of the fractional spaces generated by this operator is investigated. Furthermore, the positivity of this operator in Hölder spaces is proved.     

REACTION TIME AND INTELLIGENCE

The limited capacity theory is often cited to account for negative correlations between choice reaction time and different IQ measures. It is claimed, since working memory has strictly limited capacity to process a great amount of vital information and STM information decays if not rehearsed, that speed is an indispensable condition of efficient dealing with cognitive tasks. It ensures good performance before important information is forgotten. In the present experiment a special kind of task was applied‐one which supposedly puts a substantial load on the system of working memory. It was hypothesized that subjects dealing well with this task would also obtain high scores on general ability tests. The data obtained from 48 psychology students in the self‐paced, computer assisted study did not confirm this hypothesis. The data are interpreted as posing a challenge for the limited capacity theory, which must either be reformulated or replaced by better elaborated theoretical constructions.
