论古代文人的号、自况、自题像赞的文化内涵

本文论证了中国古代文人的“号”、“自况”、“自题像赞”的文化内涵，往往与当时社会历史、政治气候、民族传统、文化心理等有着非常紧密的联系；浓缩着广阔的社会生活，积淀了深厚的历史文化内容；是作家志趣、爱好、德行、情操、经历，以及审美倾向的全息摄影，具有不可替代的认识意义和审美意义。     

汉代画像中的“事死如事生”观念与孝道思想探讨

汉代画像是埋入地下的一种特殊的画作,是两汉时期厚葬之风的产物。这种性质决定了它的特殊性,从图像内容到表现形式都服务于墓主人,与丧葬礼俗有着密切的关系。对幽冥世界的关怀与想象,始终是汉代画像着意表现的一个非常重要的主题。这个主题有着丰富多彩的内容,譬如由体现孝道思想而产生的“事死如事生”观念,在汉代画像里便有生动而深刻的反映。     

… I ever loved thee,lady mine,and yet my love increases: Rhodian Portrait Ceramics and Cultural Dialogue in the Mediterranean

The medieval city of Rhodes kept a secure position as artistic and commercial crossroads, where pottery was the most intensely traded commodity. Here, I focus on a group of fifteenth-century ceramics decorated with profile busts of men and women excavated there, near the Orthodox Church of St. Spyridon. Used in a culturally complex urban centre, these vessels borrowed elements of design, and the concept of portrait-ceramics and love pots from Italy, where spouses and lovers exchanged such objects as ritual gifts. I explore the patronage, production, and function of these ceramics within the specifics of Rhodes, to see how they were suited to serve this cosmopolitan society governed by the Hospitaller Knights of St. John of Jerusalem, while displaying comparable feelings of power and (romantic) character common in Italian portraiture.     

历史镜像与墓中祈福:汉代“泗水捞鼎”画像意义再探

"泗水捞鼎"故事在早期文献中本身带有扑朔迷离的色彩,而汉代依据该故事创作的画像则更使该题材的图像意义具有多元化的特征。在学界研究汉代"泗水捞鼎"画像意义的基础上,重点对"楼阁人物"式"泗水捞鼎"画像意义进行考证,尤其注意到这类画像实含有为死者及其家人共同祈福的含义。反映了汉魏晋时代一些墓葬中具有祈福、喜庆等信念共同特征。     

汉代的冶铁技术与画像石

画像石是一种独特的墓室墙壁装饰艺术,可以称之为"石刻的壁画"。汉画像石作为汉代别具特色的重要体现,既受当时经济、政治、文化、科技、思想等各方面的影响,又反映着这些问题,特别是汉代冶铁技术和铁器生产无论从数量上还是从质量上都获得长足发展。我国古代的冶炼技术绝大部分在此时已达到成熟程度,这些在汉画像石中有着明显的体现,这也让我们从一个侧面了解到汉代的冶铁技术发展状况。     

Portraits of resilience: headteachers in two different cultures

This article provides two ‘portraits’ of headteachers in primary schools in England and Hong Kong, derived from semi-structured interviews with these individuals. Contrary to some claims that such a small sample is worthless, this article argues that what is most meaningful is sometimes derived from the singular and unique; that generalisations in education are as likely to be useful if they are ‘fuzzy’ generalisations as if they are from scientific or statistical generalisations; and that the individual case can strip away the clutter of large contexts and allow recognition of a common shared humanity. What these portraits also show is that responses to larger contexts are heavily dependent on personality and local context, and that if policy implementation and professional development are to have impact, then an attention to the personal and the local are going to be critical factors in any success in these areas.     

“互联网+教育”的课程智能适配

新冠疫情背景下在线教育成为全球共同选择。随着在线教育资源的极大丰富以及教师和学生时空上的隔离,如何实时了解学生学习状态以便为教师提供有效教学反馈,如何为学生提供合适在线教育资源以满足差异化需求,成为在线教育亟待解决的问题与挑战。围绕网络课程智能适配方案,构建学生标签大数据平台,重点分析用户数据分类、获取方式及完整学生画像体系设计方法;结合多属性决策模型,探讨网络课程评级与分类方法;基于协同过滤匹配度算法,探讨实现学生和课程的精确推荐方法。网络课推荐方法不仅有助于提高网络课程利用率,也有助于根据学习者个人特征开展更加灵活有效的网络课程教学。
