宋词中的长安意象

长安在中国历史上有着非常重要的地位,尤其是在盛唐,对中国乃至世界都产生了深远的影响。长安已经成为一个文化符号,在不同的时期,长安意象又表现出不同的文化意蕴。宋词中的长安意象,更显得萧索冷清、哀婉凄凉,从而反映出宋代的社会状况和宋人的精神风貌,寄寓词人政治失意的苦闷和对都城的怀念以及对收复失地的渴望,在一定程度上也反映了长安在宋代经济、政治地位的下降。以及宋人对国家、社会的某些寄托和希望。     

The effect of image quality,repeated study,and assessment method on anatomy learning

The use of two‐dimensional (2D) images is consistently used to prepare anatomy students for handling real specimen. This study examined whether the quality of 2D images is a critical component in anatomy learning. The visual clarity and consistency of 2D anatomical images was systematically manipulated to produce low‐quality and high‐quality images of the human hand and human eye. On day 0, participants learned about each anatomical specimen from paper booklets using either low‐quality or high‐quality images, and then completed a comprehension test using either 2D images or three‐dimensional (3D) cadaveric specimens. On day 1, participants relearned each booklet, and on day 2 participants completed a final comprehension test using either 2D images or 3D cadaveric specimens. The effect of image quality on learning varied according to anatomical content, with high‐quality images having a greater effect on improving learning of hand anatomy than eye anatomy (high‐quality vs. low‐quality for hand anatomy P = 0.018; high‐quality vs. low‐quality for eye anatomy P = 0.247). Also, the benefit of high‐quality images on hand anatomy learning was restricted to performance on short‐answer (SA) questions immediately after learning (high‐quality vs. low‐quality on SA questions P = 0.018), but did not apply to performance on multiple‐choice (MC) questions (high‐quality vs. low‐quality on MC questions P = 0.109) or after participants had an additional learning opportunity (24 hours later) with anatomy content (high vs. low on SA questions P = 0.643). This study underscores the limited impact of image quality on anatomy learning, and questions whether investment in enhancing image quality of learning aids significantly promotes knowledge development.

续写的传奇——中国现代小说传奇特征略论

若将传奇小说视为一种文言创作的小说体裁,它在五四前后可以说已基本消亡,然而它所蕴涵的许多审美风格、母题原型和叙事模式,结构框架等则仍然留存在中国现代小说中,从这个意义上说,传奇作为一种风格和内在叙事要素,是依然留存在现代小说当中并得到了新生。     

The effect of short-term educational travel programs on environmental citizenship

Short-term study abroad is the fastest growing area of international education and there is increasing interest in the role of modified applications of this form (e.g. faculty-led, field/environmental, and/or educational travel) in influencing global citizenship. Using an empirical database of over 650 students registered for a study abroad course in sustainable development offered in Australia and New Zealand, we explore the effect of short-term educational travel programs on environmental citizenship. We also identify differences among key student characteristics (past study abroad experience, gender, and program destination) in influencing citizenry. Results show that participation in the educational travel program significantly moderates (decreases) the difference in environmental citizenship scores for first-timers (vs. those with past experience in study abroad) and program destination, but increases the difference in environmental citizenship for males vs. females. Implications for destination image and national brand marketing of environmental-oriented educational travel programs are discussed.     

纹理谱直方图与潜在语义标引在图像检索中的应用

提出一种新的描述局域像素灰度变化的纹理谱方法,并将该方法抽取出的纹理谱直方图特征用于图像检索。实验表明该特征计算简单,检索结果较好,是一种适于图像检索的底层特征。同时将应用于文本检索领域的潜在语义标引方法用于图像检索,并提出了一种计算近似矩阵秩的方法。实验结果显示使用该方法可以分析图像中存在的隐含语义结构,并提高检索效率。

QuickBird全色与多光谱影像融合方法比较研究

自从高分辨率卫星影像出现以来,遥感影像的融合一直是一个重要的研究领域。随着遥感影像获取手段的增加和分辨率的提高,影像的融合不仅仅要求增加空间信息而且在原始多光谱波段的光谱保持方面也有越来越高的要求。目前图像融合已研究出多种方法,如主成分变换法(PCA)、乘积法、Brovey变换法、IHS变换法、SVR变换法以及小波变换法等。这些方法在中低分辨率影像融合时效果较好但却不一定适用于像QuickBird、IKONOS等高分辨遥感影像的融合。本文应用Pansharp变换法和Gram-Schmidt变换法两种融合方法,对QuickBird影像进行融合试验,并与Brovey变换法、IHS变换法、PCA变换法的融合效果进行比较,以评价各算法的优缺点。研究结果表明,Gram-Schmidt变换和Pansharp变换在QuickBird影像融合时不仅能增加空间信息而且还能较好地保持原多光谱波段的光谱信息,其中以Gram-Schmidt变换法所获得的效果最好。     

基于直方图相交匹配函数的图像压缩评测准则

常用的基于均方根误差（RMSE）图像保真度准则不能准确地放映一些灰度图像主要敏感细节。本文提出了利用灰度直方图的相似度作为评价重建图像质量的准则。利用JPEG方法对图像进行压缩,并采用直方图相交匹配函数求得图像灰度级的匹配程度。实验结果表明,直方图相交匹配函数是一种有效的图像压缩评测准则。     

论民主政治在加速中国和平崛起中的十大作用

＂和平崛起＂是中国人选择的一条强国之路,也是一项现代化的系统工程。在这项系统工程中民主政治具有最核心的价值和最决定性的力量,它将对中国社会的历史进程产生其它任何力量难以匹敌的推动力。文章认为民主政治对中国和平崛起的巨大作用有：一、能有效地选拔陶造卓越领袖——权力代理人;二、能有效地防止权力腐败和权力庸渎;三、能有效地保障公民权利、实现社会公平正义;四、能有效地良化法制结构实行法的治理;五、能有效地促进经济健康持续发展;六、能更大限度地开发国民智力、提高国民素质;七、能有力地促进科学文化繁荣;八、能更多地提高国民幸福指数;九、能有效保障国家和谐稳定、长治久安;十、能更好地提升国家形象、增加民族美誉度。
