CONTENTdm Digital Collection Management Software and End-User Efficacy     

《Journal of Web Librarianship》2013,7(2-3):339-379

ABSTRACT

Digital libraries and collections are a growing facet of today's traditional library. Digital library technologies have become increasingly more sophisticated in the effort to provide more and better access to the collections they contain. The evaluation of the usability of these technologies has not kept pace with technological developments, however, and the end-user has in some cases been left behind. This research study evaluates the usability of digital collections created using the CONTENTdm Digital Collection Management System, a software system used by the University of North Carolina at Chapel Hill. Specifically, this study addresses the following questions: Does CONTENTdm meet users' needs? Is the interface sufficiently intuitive for them to use it? Is the experience of exploring digital collections using CONTENTdm satisfying to users? Employing usability testing techniques with actual-end users, this study attempts to assess the efficacy of the CONTENTdm public interface as well as user attitudes toward it. Ten participants from three user groups—faculty, library science graduate students, and the general public—performed eleven tasks designed to test the key functions of CONTENTdm-created collections and then answered a series of questions about their experiences. Key findings from this study indicate that while the included digital collections are useful and desirable to end-users, the interface generated by CONTENTdm can be confusing even for those who have considerable experience using the Internet. Results from this study may be used to improve this software system and add to the literature surrounding the usability of digital libraries in general.  相似文献   

An Exploration of Indexed and Non-Indexed Open Access Journals: Identifying Metadata Coding Variations     

《Journal of Web Librarianship》2013,7(2-3):65-84

The intent of this investigation was to learn what factors may have contributed to low usage of a small set of reputable open access scholarly journals, as evidenced in graduate student reference lists. Inquiry into differences among open access sources referenced between 2005 and 2014 revealed that non-indexed journals were being used notably fewer times than their commercially indexed counterparts. A comparison of HTML source code between indexed and non-indexed journals illustrated that certain metadata and other coding features may have affected the visibility of non-indexed journal content. The study suggests to librarians the presence of less visible empirical literature on the web and to smaller, independent academic publishers, the need to apply better quality metadata and optimization strategies to their open access journal content.  相似文献   

“雪中送炭”还是“锦上添花”——社会网络对消减数字化贫困的价值探究     

闫慧 《中国图书馆学报》2018,44(2):17-26

本文研究问题包括:多种数字化贫困现象如何在现实社会个体身上组合起来,社会网络对哪些数字化贫困者来说是雪中送炭,对哪些数字化贫困者来说是锦上添花。论文深入挖掘中国六个省市乡村田野研究搜集的117位数字化贫困者和47位非数字化贫困者的个案数据,客观评估其数字化贫困特征值,精确描述所涉个案的数字化贫困程度及类型;发现强关系和弱关系与现实中不同数字化贫困类型叠加后的个体的数字化求助行为之间的关联。研究发现:社会网络对消减数字化赤贫者的数字化贫困程度没有明显影响;个体数字化贫困类型叠加越多,他们获得社会网络的有效支持程度越小;个体数字化贫困类型叠加越少,他们获得社会网络有效支持的可能性就越大;强关系对脆弱的数字化贫困者、数字文盲、懒惰的数字化贫困者、孤独的数字化贫困者和徒劳无益者有价值;弱关系则仅对孤独的数字化贫困者有价值。图1。表3。参考文献20。  相似文献   

新型16位模/数转换器AD7715的应用数字电压表的设计     

黎晓贞  朱敏  舒洪 《科技广场》2008,(3):210-211

AD7715是美国Analog-Devices公司生产的高精度模/数转换芯片,片内含有可编程增益放大器、可编程数字滤波器和寄存器,采用Σ-Δ转换技术实现16位的精确测量。本电压表采用89C55单片机作为控制器,采用模拟开关进行多级切换对被测电压经过信号调理,采用新型16位模/数转换器AD7715对调理后的被测电压进行采样,采用128X64点阵式液晶显示屏作为显示器,实现波形和汉字显示。本文简明地介绍了应用AD7715芯片进行高精度电压表设计的方法。  相似文献

Taxonomy of e-readiness assessment measures   总被引：1，自引：0，他引：1  

Payam Hanafizadeh  Mohammad Reza Hanafizadeh  Mohsen Khodabakhshi 《International Journal of Information Management》2009

To benefit from the advantages of information society, on the one hand, and to be afraid of being left further behind by Global Society and the increase in the digital divide, on the other hand, stimulate countries to be part of Global Information Society. These issues have led policymakers to move towards such a society by identifying the objectives, goals and targets. Planning to achieve these objectives needs a real understanding of the current situation, which is obtained by e-readiness assessment measures. There has been a proliferation of e-readiness assessment measures in recent years that each one has a certain objective. This paper elaborates on and categorizes these measures that help scholars and policymakers to (1) select the measures that fit in with their objectives, (2) prevent the repetitive research, (3) identify the defects and flaws of previous measures and correct them in their own measures, and (4) use the experiences of previous measures to construct their own ones. Based on definitions, objectives, dimensions, methods and approaches, in this paper, the measures are categorized and finally, a measure for e-readiness assessment is presented. Since this measure is a convergence of e-readiness assessment measures, the experienced modelers have consensus on it and it is more suitable to measure e-readiness of countries. Also, it can be exploited as the basis and standard for internationally comparable information society statistics.  相似文献
