Automated Classification to Improve the Efficiency of Weeding Library Collections

Previous studies have shown that weeding a library collection benefits patrons and increases circulation rates. However, the time required to review the collection and make weeding decisions presents a formidable obstacle. This study empirically evaluated methods for automatically classifying weeding candidates. A data set containing 80,346 items from a large-scale weeding project running from 2011 to 2014 at Wesleyan University was used to train six machine learning classifiers to predict a weeding decision of either ‘Keep’ or ‘Weed’ for each candidate. The study found statistically significant agreement (p?=?0.001) between classifier predictions and librarian judgments for all classifier types. The naive Bayes and linear support vector machine classifiers had the highest recall (fraction of items weeded by librarians that were identified by the algorithm), while the k-nearest-neighbor classifier had the highest precision (fraction of recommended candidates that librarians had chosen to weed). The variables found to be most relevant were: librarian and faculty votes for retention, item age, and the presence of copies in other libraries.     

基于用户馆体验视角的图书馆服务平台选择思考

[目的/意义] 传统的集成图书馆系统（ILS）正在被图书馆服务平台（LSP）所取代,国内许多高校图书馆致力于对ILS的评估和对LSP的考察。然而,LSP的产品多种多样,图书馆很难决定哪种LSP最适合他们。对目前LSP主流产品的市场格局、发展情况进行分析,旨在为计划由ILS转向LSP的高校图书馆决策提供参考。[方法/过程] 基于国外高校图书馆使用LSP的体验和感知,对市场上主要的图书馆服务平台进行分析、评估和总结。[结果/结论]由于ILS/LSP市场的整合,LSP供应商数量正在缩减,目前只有Alma、Sierra和OCLC WMS得到充分实施。此外,开源项目FOLIO的推出为图书馆提供了另外一种思路。但目前这种单一的整合性图书馆服务平台不是解决方案,基于平台由若干松散耦合的组件构成的图书馆生态系统,才是图书馆真正的下一代服务平台,自主创新,研发适合国内图书馆环境的下一代开放服务平台迫在眉睫。     

创客时代高校图书馆读者创客素养培育探究

[目的/意义]培育读者的创客素养是发展读者核心素养的关键之一,通过提出培育创客素养的有效途径,为在创客时代提升读者创客的创客素养提供借鉴。[方法/过程]基于创客素养教育涵义的分析,对创客素养包含的创客意识、创客道德、创客能力、创客技术和创客精神5个方面内容进行阐述,提出图书馆应通过采取转变思维观念、打造创客环境、渲染创客空间范式、培育不同创客DNA、支持组建创客团队等8种培育创客素养的途径。[结果/结论]图书馆应把握好双创教育的发展态势,正确实行空间再造,积极开展创客活动并实施创客素养教育,真正担当起双创教育的职责,为构建良好的校园创客文化做出贡献。     

Sampling Methods and Sample Populations in Quantitative Mass Communication Research Studies: A 15-Year Census of Six Journals

This study evaluated the sampling methods and sample populations used in all U.S.-based survey and experimental mass communication studies published between 2000 and 2014 in six major journals (N = 1,173). Most studies used nonprobability samples, and more than half used student samples. Experiments used more nonprobability and student samples than surveys. Funded studies used more probability and nonstudent samples than nonfunded studies. Implications of results pertaining to population validity and interpretations of findings for mass communication research are discussed.

High-entropy-alloy nanoparticles with 21 ultra-mixed elements for efficient photothermal conversionOA

Multi-metallic nanoparticles have been proven to be an efficient photothermal conversion material, for which the optical absorption can be broadened through the interband transitions(IBTs), but it remains a challenge due to the strong immiscibility among the repelling combinations. Here, assisted by an extremely high evaporation temperature, ultra-fast cooling and vapor-pressure strategy, the arc-discharged plasma method was employed to synthesize ultra-mixed multi-metallic nanoparticles compose...
