电子书用户使用意愿影响模型构建与实证

[目的/意义] 探究用户使用电子书意愿的影响因素，以有助于电子书产业走出缓慢的发展困境。[方法/过程] 以UTAUT2、使用满足理论为基础，从需求满足和外部情景因素两个层面构建影响因素模型，并将需求满足细化为内容需求、社交互动需求和休闲娱乐需求3个测量变量。采用问卷调查方法收集有效样本1 013份，使用AMOS21软件对模型进行验证。[结果/结论] 研究发现，需求满足、阅读习惯、价格价值、社会影响对使用意愿有正向影响作用，而激励措施对使用意愿有负向影响作用，努力期望对使用意愿的影响不显著，并依据研究结果提出促进电子书产业发展的建议。     

Influence of Process Parameters on Chlorinated Biocide Decontamination by li-CO2 on Artificially Contaminated Model Materials

ABSTRACT

Previously, heavy use of biocides for the treatment of objects made of organic materials in museum collections (e.g. ethnographic, historical collections) was very common. Now suitable decontamination methods/technologies are being sought. A decontamination treatment by li-CO₂ was optimized that considered the specific requirements of museum objects. The treatment was tested on model materials artificially contaminated with biocide solutions containing dichlorodiphenyltrichloroethane (DDT), pentachlorophenol (PCP), lindane, and permethrin or cypermethrin. High decontamination was achieved for DDT, lindane, PCP, and permethrin on artificially biocide loaded wool and wood model materials. Optimal process parameter settings for li-CO₂ decontamination include a single 30?min cycle for woolen materials and three sequential 30?min cycles each for wood. These methods allow a reduction of at least 90% of all biocides for wool and between 70% and 85% for wood. Decontamination of the latter was more effective for less polar biocides as DDT and permethrin. Despite a significant improvement in decontamination for wood using co-solvents such as acetone, ethanol, and methyl tertiary-butyl ether (MTBE), their use is not recommended due to the increased risk of damage to the objects, in particular if a surface coating is present.     

MARC to BIBFRAME: Converting the PCC to Linked Data

Abstract

The Program for Cooperative Cataloging (PCC) has formal relationships with the Library of Congress (LC), Share-VDE, and Linked Data for Production Phase 2 (LD4P2) for work on Bibliographic Framework (BIBFRAME), and PCC institutions have been very active in the exploration of MARC to BIBFRAME conversion processes. This article will review the involvement of PCC in the development of BIBFRAME and examine the work of LC, Share-VDE, and LD4P2 on MARC to BIBFRAME conversion. It will conclude with a discussion of areas for further exploration by the PCC leading up to the creation of PCC conversion specifications and PCC BIBFRAME data.     

Behavioral Intention to Adopt Digital Library by the Undergraduates

The purpose of this research is to investigate the factors that affect undergraduates' behavioral intention to use digital library among the private universities in Malaysia. The target respondents are undergraduates from Malaysian private universities. Questionnaires were distributed among 500 undergraduates through either online or face-to-face method. Reliability test, normality test, Pearson Correlation Coefficient analysis, and Multiple Linear Regression (MLR) were carried out for data analysis. Performance expectancy, social influence, facilitating conditions, hedonic motivation, habit, and information quality had a positive and significant association with behavioral intention to adopt a digital library except for effort expectancy. This research successfully reinforced that the inspiration to ameliorate Unified Theory of Acceptance and Use of Technology 2 (UTAUT 2) by synthesis of Information Systems Success Model (ISSM). This proposed framework with a combination of ISSM and UTAUT 2 has enhanced the fitness of UTAUT 2. Universities that have yet to implement digital library can comprehend undergraduates' needs better by considering all the significant factors to develop a digital library. The universities with the digital library may also notice the important features of the existing digital library that should be maintained and upgraded constantly so that they can fulfil undergraduates' requirements.

一个学科内“小同行”数量和质量是衡量学科发展水平的重要指标。论文对我国高校LIS学科高级专家群体CSSCI来源期刊论文的统计分析,初步区分出61位高产专家中的14个“小同行”群体。并对我国LIS学科“小同行”群体发育水平较低的原因进行剖析。     

利用D2R实现关系数据库与关联数据的语义模式映射

关系型数据库和关联数据的概念模型都基于现实世界的实体、属性及其关系而构建,具备建立映射和实现转换的可能性。两者语义模式映射的重点是关联关系的构建与表达。开源软件D2R的映射语言,通过核心要素ClassMap、PropertyBridge及其属性,支持关系数据库的SQL实现,支持将关系数据库不同实体之间、同一实体内部及与外部数据的关联关系构建为RDF链接。     

语义Web模式下综合科技资源的关联策略研究

在开发综合科技资源集成登记系统的实践基础上,研究综合科技资源的关联策略,针对其在语义化方面的局限性,提出一种利用D2RQ组件将综合科技资源的关系数据源公开为RDF接口,进而利用SPARQL端点查询技术将RDF接口公开为W eb服务的优化方案。试验证明,该方案合理可行,可为综合数字资源体系建设的未来发展提供思路。
