This article presents results from a survey designed to assess the relevance of library and information science (LIS) expertise—here defined as those topics typically, but not exclusively, taught in LIS programs—for museum professionals. The topics covered in this article are information representation, information organization and access, information management, computer technologies, digitization technologies, interactive technologies, information policy, evaluation methods, and collaboration initiatives. An online survey assessed the degree to which museum professionals possess skills in these topics, perform work in these topics, and consider these topics important for future study. The article examines the relative value of each topic for museum professionals and discusses the importance of strengthening relationships between LIS and museum studies by better understanding the relevance of LIS expertise in museums.  相似文献

Whilst great emphasis has rightly been placed on the increased availability and use of health information, little research has been undertaken into the non use of such material, particularly with regard to electronic sources. Computer transactional log data from health information touch screen kiosks, collected as part of an ongoing Department of Health-funded study being carried out by City University, showed that females in the 55-74 age group were particularly under-represented as users. To explore reasons for this, in-depth interviews were carried out with 13 non-kiosk-using, primary-care out-patients fitting this profile, at a surgery which had a kiosk that was being monitored. Subjects were interviewed at length about their information needs and information-seeking behaviour, to determine reasons (if any) they might have had for non-kiosk use. The study utilized an interview schedule and technique loosely based on the 'Sense-Making' methodology of Brenda Dervin (Talk Presented at the International Communication Association Annual Meeting, May 1983, Dallas, Texas, USA. Available from: http://communicationsbsohio-stateedu/sense-making/art/artdervin83html.). Findings elicited many factors accounting for non use of the system. The first and major source of information remained the doctor, with written or other sources only being consulted where recommended or provided. There was evidence that patients wanted little more than the minimum information or instructions required to deal with their condition. Many appeared unaware of the presence of the kiosk and others assumed either that it was not for patient use or that it would not serve their needs. The methodology proved itself, with certain caveats, to be an appropriate vehicle for this kind of exploratory work.  相似文献

This paper describes the highlights of an exploratory deep log analysis of journal usage on OhioLINK, conducted as part of the MaxData project. OhioLINK, the original ‘Big Deal’, provides a single digital platform of nearly 6,000 full‐text journals for more than 600,000 people in Ohio and the investigation aimed to assess it after approximately 10 years. The data was generated from an SPSS analysis of the raw (unprocessed) server logs for June 2004 to December 2004. Approximately 1,215,000 items were viewed on campus in October 2004 and 1,894,000 items viewed off campus between June and December 2004. There are a number of usage analyses including: demand and activity; number and name of journal; date of publication; subject/discipline of journal and method of searching/navigating.  相似文献

In the United States, a number of federal laws establish requirements that electronic government (e-government) information and services be accessible to individuals with disabilities. These laws affect e-government Web sites at the federal, state, and local levels. To this point, research about the accessibility of e-government Web sites has tended to focus on compliance with Section 508 of the Rehabilitation Act. Though Section 508 has the most specific guidelines regarding Web site accessibility, it is hardly the only law establishing accessibility requirements for e-government Web sites, and Section 508 does not apply to many sites that may be required to be accessible by other laws. Until assessment of the accessibility of e-government Web sites accounts for all of the relevant laws, the understanding of levels of accessibility and compliance will be incomplete. This article examines the entire spectrum of federal laws that create legal requirements for accessible e-government Web sites, analyzing the accessibility requirements that the laws establish and the ways in which each of the laws applies to an e-government Web site. This article also suggests research areas that should be included in future assessments to address the entire range of laws related to the accessibility of e-government Web sites. The issues raised in this article have significant relevance to the design and development of e-government, to the assessment of e-government information and services, and to the inclusion in e-government of the 54 million individuals in the United States with disabilities.  相似文献

The Institution of Electrical Engineers (IEE) has changed its approach to member publications over a two‐year period with an increased focus on understanding the needs of its broad membership and structuring its portfolio of magazines and websites to meet members' needs and complement the organization's research publications. The process of market research and product development is outlined in this article and the resulting combination of online and print products described. The products have been well received by IEE members and the wider community and have been recognized within the publishing industry with important awards in the business‐to‐business and not‐for‐profit sectors.  相似文献
