从色彩的递变窥探李煜词的艺术自述性

南唐后主李煜被誉为“千古词帝”。他的词由心而作,缘情而胜,洋溢着一往而深的真诚和毫不矫饰的纯情,在这些毫无矫饰的词作中充斥着大量斑斓的色彩意象。李煜一生也如色彩意象一般,从未平淡。笔者在对后主词进行了梳理性的分析后,力图通过对这些色彩意象的解读,探究后主词中色彩意象的特征、成因,及其背后藏匿的情感内涵等等。

国家级文科综合实验教学示范中心的组织架构——基于协同论的思考

系统的组织架构为系统的功能所决定,关乎系统的产生、发展和效率。从协同论视角分析,作为文科高等教育实验教学科研组织形式的国家级文科综合实验教学示范中心,其组织架构建立的基本规则是支撑和实现中心承载的功能,因而其必须是独立的教学科研机构。其组织架构的基本特征是建立学习型组织的扁平化结构。     

ENSO and Southeast Asian biomass burning modulate subtropical trans-Pacific ozone transport

Trans-Pacific transport of enhanced ozone plumes has been mainly attributed to fossil fuel combustion in Asia in spring, but less attention has been paid to vegetation fires in Asia. Here we show that the El Niño-Southern Oscillation (ENSO)-modulated fires in Southeast Asia, rather than Asian fossil fuel plumes, dominate the interannual variability of springtime trans-Pacific transport of ozone across the entire North Pacific Ocean. During El Niño springs, the intensified fires from both the Indochinese Peninsula and Indonesia, together with large-scale circulation anomalies, result in enhanced ozone plumes that stretch over 15 000 km in both the lower-middle and upper troposphere. This enhancement is also observed in the in situ measurements of ozone concentration, with an almost 10% increase at Mauna Loa Observatory, Hawaii, a unique site to monitor the long-distance transport over the North Pacific. This study reports an unexpectedly strong influence of vegetation fires, linked with climate variability, on global tropospheric chemistry and proves once more how complex the interactions in the climate system are.     

EFFECTS OF AGING ON SELECTED ACOUSTIC VOICE PARAMETERS: PRELIMINARY NORMATIVE DATA AND EDUCATIONAL IMPLICATIONS

The study reported in this article attempted to obtain normative acoustic data of voice for elderly male and female speakers and to explore the educational implications of the effects of aging on those selected acoustic parameters. Voice samples from 21 male and 23 female elderly speakers aged 70 to 80 years were obtained on measures of 15 selected Multi-Dimensional Voice Program acoustic parameters. These data then were compared with the published norms for young and middle-aged adults. The results showed that, compared with young and middle-aged adults, elderly speakers had significantly different (usually poorer) vocal output on all of the selected acoustic parameters of voice. These findings illustrate the importance of establishing acoustic norms and thresholds for elderly men and women and stress the necessity of using discretion in making dragnostic measurements of elderly speakers' acoustic parameters of voice. This article also highlights the educational implications of such aging voice changes.
