Why Users Share the News: A Theory of Reasoned Action-Based Study on the Antecedents of News-Sharing Behavior

Social media have become an integral part of online news use, affecting how individuals find, consume, and share news. By applying the Theory of Reasoned Action (TRA), this study investigates the effects of motives, attitude, and intention on news-sharing behavior among German social media users (n = 333). Findings show that news-sharing attitude and subjective norms have a positive effect on news-sharing intention, which in turn has a positive effect on actual news-sharing behavior. Taken together, we see that a new media behavior in the early phases of its societal diffusion—like social media news sharing in Germany in 2015—can mainly be explained by a rational choice logic and is rooted in the motives of socializing and information seeking. This finding thus reflects the double nature of social media as a means for both information retrieval and social grooming.     

上海图书馆藏四册抄本《松隐文集》卷十四辨伪——兼考《全宋诗》曹勋卷重出诗歌之归属

上海图书馆藏四册抄本《松隐文集》为弥补原第十四卷散佚的缺憾,从《宋诗抄》中抄录杨万里、许月卿、方岳、林景熙、文天祥、郑震的诗歌共28首,拼凑成第十四卷,其为伪作无疑。《全宋诗》所收录的该卷诗歌当剔除。同时上海图书馆将该书著录为明抄本,当改为清抄本。     

历史地理信息的获取与标准化——以上海交通大学馆藏地方历史文献为例

上海交通大学图书馆针对近年来收集的地方历史文献开展了数字化加工工作。如何有效地提取文献蕴含的地理信息并使其标准化,最终实现数字化的展示、利用与分析是工作的难点之一。地理信息经由人工获取,根据研究需求按照分段揭示的原则著录到地域相关的元数据字段中。基于可统计的文献来源,分布集中的文献优先编写代码转换规则,可机读代码避免了语义识别等程序的繁冗。鉴于明清时期行政区划的特点,代码采用"省-县-都-图-村"五级格式,遵照标准化、兼容性、求同性与扩展性的编制原则,以期实现文献关联聚类、信息自动获取与空间可视化等数据化效果,还原地域视角下的历史原貌。     

Managing a Biomedical Library’s Instruction Program: Redefining Scope

The National Institutes of Health (NIH) library instruction program provides training services to staff, clinicians, and researchers across NIH and several Department of Health and Human Services (HHS) operating divisions. The audience, training needs, and training topics are diverse and constantly changing. The NIH library has developed several new services and class topics to meet the needs of its NIH and HHS communities. Context, strategies, and future directions for the NIH library instruction program are described.     

信息科学研究中档案研究的边缘化问题及其突破——基于对iConference2017的分析与思考

2017年3月22日至25日,iConference在中国武汉召开。以此次实际参会经验和会议文本分析为基础,本文提出,在信息社会,档案研究在信息科学研究中正在呈现日趋明显的边缘化发展态势,这将不利于档案研究自身的健康发展以及其与相关学科展开有效对话。在对突破这种边缘化的契机进行分析的基础上,本文对档案研究的未来发展提出了建议,即强调档案研究应该重新找准定位,拓宽研究领域和研究范围,最终建立其在信息科学研究中的话语空间。     

基于文件连续体理论模型的“第五维度理论”

从文件生命周期理论到文件连续体理论,档案界对文件运动形式的理解从线性向多维转变。在后现代主义档案观的影响和跨界合作的时代背景下,四维的文件连续体理论模型逐渐向五维演变。本文以加拿大档案学者勒梅教授及其团队提出的“第五维度理论”为基础,认为应该充分考虑利用者在档案工作流程中的作用,同时将对档案的“探索”性开发看成是对文件连续体理论模型的第五个维度。     

王阳明著述的两个版本略考

王阳明之所"立言",版本甚多,然有明隆庆谢氏刻本《王文成公全书》和明崇祯施氏刻本《阳明先生集要》乃为显本,两本各有殊同,皆为读研阳明思想学说最重要的文献资料。     

Forward view: advancing health library and knowledge services in England

This article is the fourth in a series on New Directions. The National Health Service is under pressure, challenged to meet the needs of an ageing population, whilst striving to improve standards and ensure decision making is underpinned by evidence. Health Education England is steering a new course for NHS library and knowledge services in England to ensure access to knowledge and evidence for all decision makers. Knowledge for Healthcare calls for service transformation, role redesign, greater coordination and collaboration. To meet user expectations, health libraries must achieve sustainable, affordable access to digital content. Traditional tasks will progressively become mechanised. Alongside supporting learners, NHS librarians and knowledge specialists will take a greater role as knowledge brokers, delivering business critical services. They will support the NHS workforce to signpost patients and the public to high‐quality information. There is a need for greater efficiency and effectiveness through greater co‐operation and service mergers. Evaluation of service quality will focus more on outcomes, less on counting. These changes require an agile workforce, fit for the future. There is a bright future in which librarians’ expertise is used to mobilise evidence, manage and share knowledge, support patients, carers and families, optimise technology and social media and provide a keystone for improved patient care and safety.
