Evaluating Consumer Health Information: What Fails to Harm Us Makes Us Smarter

Freely available health information on the Web often requires academic librarians to evaluate content on-the-fly. Studies indicated a significant number of health web sites do not measure up to research standards. Instruments that evaluate web sites have themselves performed unevenly and a standardized instrument has yet to be realized. Instruments for evaluating health information relatively quickly are presented so librarians can familiarize themselves with the process. The debate concerning whether health web sites possess harmful or potentially harmful content is reviewed. Librarians are encouraged to work with teaching faculty and urge students to look beyond currency, authority, and advertising and apply rigorous criteria.

Pakistani University Library Web Sites: Features,Contents, and Maintenance Issues

ABSTRACT

This study explores the current status and features of Pakistan's academic library Web sites. A checklist describing features and content was prepared based on a review of the literature related to academic libraries’ Web sites. Then, all 85 library Web sites of Pakistani universities and degree-awarding institutions recognized by the Higher Education Commission (HEC) of Pakistan were surveyed and analyzed using the checklist. Interviews with library professionals were conducted to learn more about the problems and issues with building and maintaining library Web sites. Results indicate that Pakistani academic library Web sites have effective features such as contrasting color schemes, easily readable text, minimal use of horizontal scrolling, and English-language text. Staff information, OPACs, and navigation features are also widely found on the Web sites. Features found less frequently include the use of Web 2.0 technologies, Web site aid tools, information about library buildings, and general library information. By offering information about the status of Pakistani academic library Web sites, the study can serve as a foundation for discussion between libraries and other parts of the university, as well as a benchmark for evaluating the progress of academic library Web sites in Pakistan

How global companies communicate in host country: a glocalization strategy in web space

Corporate web sites have significant roles in building a positive image with stakeholders, particularly in a host market environment with different cultural backgrounds and values. A content analysis was conducted to study the glocalization strategies of corporate web sites and depiction of cultural values of 47 international brands which were identified as having Indonesian web sites. The four types of glocalization strategies of corporate web site content differed in the depiction of cultural values on their web sites. The differences could be found in overall analysis and four of five cultural dimensions such as collectivism, uncertainty avoidance, power distance and high context communication. It integrates the theory of glocalization strategy and cultural values in the context of cyberspace, which represents a pioneering attempt in investigating the aforementioned issue.     

Examining the role of Web site information in facilitating different citizen–government relationships: A case study of state Chronic Wasting Disease Web sites

This paper develops a framework to assess the text-based public information provided on program level government agency Web sites. The framework informs the larger e-government question of how, or whether, state administrative agencies are using Web sites in a transformative capacity—to change relationships between citizens and government. It focuses on assessing the degree to which text information provided on government Web sites could facilitate various relationships between government agencies and citizens. The framework incorporates four views of government information obligations stemming from different assumptions about citizen–government relationships in a democracy: the private citizen view, the attentive citizen view, the deliberative citizen view, and the citizen–publisher view. Each view suggests inclusion of different types of information on government agency web sites. The framework is employed to assess state Web sites containing information about chronic wasting disease, a disease effecting deer and elk in numerous U.S. states and Canada.

EAD Encoding and Display: A Content Analysis

ABSTRACT

The study investigated implications of variations in EAD-encoded finding aids on the Web. A content analysis methodology was used to examine five different aspects of EAD finding aids: (1) data elements; (2) labeling terminology; (3) navigation; (4) browsing; (5) searching. Seventeen EAD finding aid web sites selected from 161 RLG member institution web sites, were examined. The results of the study showed that variations in EAD finding aids existed. These include inconsistency in the use of data elements, labeling terminology, and browsing attributes. In addition, some of the EAD finding aid web sites did not provide navigational aids within a finding aid or search functions for access to it. Findings suggest that increased navigational aids, as well as more browsing and search functions are needed to provide better access to EAD-encoded finding aids.

Services for Graduate Students: A Review of Academic Library Web Sites

A library's Web site is well recognized as the gateway to the library for the vast majority of users. Choosing the most user-friendly Web architecture to reflect the many services libraries offer is a complex process, and librarians are still experimenting to find what works best for their users. As part of a redesign of the Oregon State University Libraries’ Web site, entry points for specific user groups were created. One of these user groups was graduate students. The purpose of this study was to explore the ways other academic libraries design their Web sites for particular user groups, specifically graduate students, in order to determine how the Oregon State University Libraries Web site compared to peer institutions. This study analyzed 112 Association of Research Libraries’ Web sites and 26 Oregon academic libraries’ Web sites to determine the availability of resources and services specifically promoted to graduate students. Since graduate students may view the library Web site through the lens of new student, researcher, or instructor, Web sites were also examined to see if sites were created with any or all of these roles in mind. Nearly a quarter of Association of Research Libraries' Web sites that were examined contained a link on the homepage for graduate students, and another 20 percent provided graduate-student information at a lower level in their site hierarchy. A majority of sites had events, subject guides, or course guides for graduate students. Information for graduate students was typically framed in the context of graduate students as researchers. Ideas and examples are given for ways to improve Web site design to better serve this user group. In order to provide improved services to these students, future studies will explore what graduate students need from academic libraries and the ways these students conduct themselves in their various roles of researchers, instructors, and new students.     

Building the Seamless Web of Cultural Research Resources

Providing integrated access to research resources thatsupport teaching and learning in the humanities andsocial sciences has been a goal of the ResearchLibraries Group since its inception in 1975.
