李白《赠汪伦》考释 ——以踏歌和送行情境为中心

踏歌之俗由来久矣.在唐代,踏歌风俗较前代更为流行.唐代踏歌承担着庆典、娱乐、祭祀、祝寿、送行等重要功能,在社会生活中占据着重要位置.李白《赠汪伦》为唐人送别名篇,现今学界对汪伦为李白踏歌送行情境说法纷纭不一,汪伦为农人或县令的身份也备受争议.结合李白原诗与现有材料分析,汪伦的身份应为县令,其携村民或家乐给李白送行的说法并不可信,踏歌乃是汪伦即兴而为.

现代信息技术环境下的文献资源建设

现代信息技术的发展,必将提高文献资源的共享程度,从而在实践上实现从"图书馆藏书建设"到"文献资源建设"的转变.提出网络化、数字化环境下的文献资源建设,需建立适合我国国情的文献事业管理机构,打破现行的四大系统隶属制,按图书情报机构的级别(中央级、省级、地市级、部分县级)以学科分类为基础,考虑专业学科特色,统筹规划,分工协调,减少不必要的重复和浪费,同时提高我国文献资源的保障率.并指出电子载体将作为文献收藏的主要载体,纸质载体作为一种补充将与电子载体并存.

Narrative accounts of US teachers' collaborative curriculum making in a physical education department

Through the use of narrative inquiry, this research study explores the collaborative curriculum making experiences of six teachers (three males; three females) in one physical education (PE) department in an urban middle school in the U.S. Collaboration; as defined in this work, this has to do with teachers’ voluntary interactions and their shared decision making in support of common goals. Where curriculum making is concerned, it refers to interactions between and among the four commonplaces of curriculum (teacher, learner, subject matter, milieu). The paper features the perspectives of the department head (female), experienced teachers (male and female) and teachers new to the profession (male and female). The narrative accounts of the individual teachers are set against the backdrop of the PE department with which they identify and within the storied history of the school in which they work. The story constellations representational form conveys the interrelatedness of the narratives and instantiates the teachers’ experiences of collaborative curriculum making. In the final analysis, this research enterprise makes a major contribution to the study of PE as well as to education generally. To date, no inquiries have focused on the collaborative curriculum making of teachers lodged in a PE department in one school context, despite collaborative curriculum making most closely reflecting how PE teachers typically approach the teaching task due to shared classrooms/gymnasiums/fields and the communal use of equipment.     

基于证据推理的核心技术识别方法研究

通过对从美国专利商标局( The US Patent and Trademark Office,USPTO)网站中下载的某领域专利进行整理,得到初始统计数据。将USPTO专利子类作为技术节点,技术之间共现关系作为边,建立技术的共现网络,再利用复杂网络中的“k-核”分析方法对共现网络进行分析,进行技术筛选。提出技术识别的层次性评估指标,运用证据推理对筛选出的技术进行评估,选出核心技术。最后以激光切割技术为例,展示和验证了此方法。
