Google Scholar's Coverage of the Engineering Literature 10 years Later

In 2008 Meier and Conkling first tested Google Scholar's coverage of the engineering literature against citations gathered from the Compendex database. Since that time, other studies have used the same methodology and found improvement in Google Scholar's coverage. This study uses engineering dissertations from Proquest Dissertations & Theses to create a data set of citations for the comparison of fee-based databases, Compendex and Scopus, against Google Scholar. From 1950 to 2017 Google Scholar outperformed both Compendex and Scopus in discoverability of citations in nine engineering subjects. These results have implications for collection management and information literacy program planning for librarians.     

Google Scholar and Web of Science: Examining gender differences in citation coverage across five scientific disciplines

Many studies demonstrate differences in the coverage of citing publications in Google Scholar (GS) and Web of Science (WoS). Here, we examine to what extent citation data from the two databases reflect the scholarly impact of women and men differently. Our conjecture is that WoS carries an indirect gender bias in its selection criteria for citation sources that GS avoids due to criteria that are more inclusive. Using a sample of 1250 U.S. researchers in Sociology, Political Science, Economics, Cardiology and Chemistry, we examine gender differences in the average citation coverage of the two databases. We also calculate database-specific h-indices for all authors in the sample. In repeated simulations of hiring scenarios, we use these indices to examine whether women's appointment rates increase if hiring decisions rely on data from GS in lieu of WoS. We find no systematic gender differences in the citation coverage of the two databases. Further, our results indicate marginal to non-existing effects of database selection on women's success-rates in the simulations. In line with the existing literature, we find the citation coverage in WoS to be largest in Cardiology and Chemistry and smallest in Political Science and Sociology. The concordance between author-based h-indices measured by GS and WoS is largest for Chemistry followed by Cardiology, Political Science, Sociology and Economics.

Using a concept mapping strategy to improve the motivation of EFL students in Google Hangouts Peer-Tutoring Sessions with native speakers

This study examines four elements of learner motivation, attention, relevance, confidence, and satisfaction, in an EFL speaking course that uses the computer mediated communication (CMC) tool Google Hangouts. The study found that a preparatory concept mapping task before the CMC sessions improved students’ perceived attention, relevance, confidence, and satisfaction. However, follow-up reflective worksheets had no effect on perceived attention, relevance, confidence, or satisfaction. Instructors should use concept mapping in a pre-task to support learners engaged in CMC-based speaking activities with native and non-native speakers. When the students used concept mapping to prepare for the CMC-based speaking activities, they exhibited higher confidence in their oral practice activities with a native speaker.     

“谷歌模式”冲击下的传统出版业创新策略

传统出版业在数字化的过程中,充当着内容提供商的角色,然而＂谷歌模式＂虽然不拥有＂内容＂,但拥有捕捉内容的能力、技术和配套的商业模式,让传统出版业受到了前所未有的冲击。传统出版业必须要在创新中求得发展：从内容提供商转向全方位数字出版服务商,确立内容资源优势,实现产品创新和技术创新;加快推动数字化转型,制订行业统一的技术标准;把握数字出版版权,打造数字出版资源平台,成立第三方监管机构改变利润分配主导权。
