无尽的苍凉--浅淡张爱玲《倾城之恋》中的悲剧色彩

论《平凡的世界》的史诗性特征

重读《平凡的世界》,仍然有一种强烈的穿越感,作品所反映的社会生活内容依然能够唤醒我们沉睡的记忆,引发精神上的强烈震撼。《平凡的世界》之所以今天仍然能够力透纸背,层层扩散波光,让人读懂、读出社会历史内涵,其根本原因在于小说真正切入现实,以及作者的史诗性写作和作品的史诗性特征。小说书写的农村改革史、农民创业史和青年奋斗史正好体现了20世纪80年代社会、家庭、个人等层面的发展、成长的历史。作品由双水村、石圪节到黄原、铜城大牙湾,由农村到城市,反映出了一个时代整体的社会风貌,具有丰富的史诗性价值。     

增加值出口竞争力研究——基于新兴经济体样本

文章使用全球投入产出数据库(WIOD),对新兴经济体样本的增加值出口和新显示性比较优势指数进行测算和分析。研究发现,近年来新兴经济体相对于发达国家出口竞争力强劲,贸易实力提升显著。细分至行业,新兴经济体在第一产业中具有绝对优势,在第二产业的低端和中低端中具备竞争力,在第三产业方面,新兴经济体在传统服务业中具备一定的优势,但在高新技术服务业不具备竞争力。因此,在保留、强化和创新现有竞争优势的同时,新兴经济体仍需要大力发展高端制造业和新型服务业,增加产品科技含量。

Comparison of three web-scale discovery services for health sciences research

Objective

The purpose of this study was to investigate the relative effectiveness of three web-scale discovery (WSD) tools in answering health sciences search queries.

Methods

Simple keyword searches, based on topics from six health sciences disciplines, were run at multiple real-world implementations of EBSCO Discovery Service (EDS), Ex Libris''s Primo, and ProQuest''s Summon. Each WSD tool was evaluated in its ability to retrieve relevant results and in its coverage of MEDLINE content.

Results

All WSD tools returned between 50%–60% relevant results. Primo returned a higher number of duplicate results than the other 2 WSD products. Summon results were more relevant when search terms were automatically mapped to controlled vocabulary. EDS indexed the largest number of MEDLINE citations, followed closely by Summon. Additionally, keyword searches in all 3 WSD tools retrieved relevant material that was not found with precision (Medical Subject Headings) searches in MEDLINE.

Conclusions

None of the 3 WSD products studied was overwhelmingly more effective in returning relevant results. While difficult to place the figure of 50%–60% relevance in context, it implies a strong likelihood that the average user would be able to find satisfactory sources on the first page of search results using a rudimentary keyword search. The discovery of additional relevant material beyond that retrieved from MEDLINE indicates WSD tools'' value as a supplement to traditional resources for health sciences researchers.
