Osorio, Nestor L. (2001). "Web Sites of Science-Engineering Libraries: An Analysis of Content and Design" [Artículo]. Issues in Science and Technology Librarianship, Winter2001, ():.

Resumen:

"Forty-five web sites from Science- Engineering Libraries of universities in the USA and Canada are analyzed according their design characteristics and hypertext links. The most common elements are then incorporated into a model home page that visually shows the predominant design characteristics and hypertext links on this type of web site. The results show that in general the current design of home pages for Science-Engineering Libraries contain many of the elements found in home pages of academic libraries. Among the characteristics found are images, screen lengths, colors, number and types of links, and link headings. The content of these web sites is also analyzed and summarized."

Resumen:

"A citation analysis of undergraduate term papers in microeconomics revealed a significant decrease in the frequency of scholarly resources cited between 1996 and 1999. Book citations decreased from 30% to 19%, newspaper citations increased from 7% to 19%, and Web citations increased from 9% to 21%. Web citations checked in 2000 revealed that only 18% of URLs cited in 1996 led to the correct Internet document. For 1999 bibliographies, only 55% of URLs led to the correct document. The authors recommend 1) setting stricter guidelines for acceptable citations in course assignments; 2) creating and maintaining scholarly portals for authoritative Web sites with a commitment to long term access; and 3) continuing to instruct students how to critically evaluate resources."

Resumen:

"Using a combination of domain names and user counts, this paper provides an assessment of the global distribution of Internet content creation at the national and urban level and the structure of the supply and demand for this content at the national level. Theories of export based development are used to assess the strengths and weaknesses of countries Internet presence and the ramifications of this for future development."

Resumen:

"This paper presents the principles for constructing high quality science and technology roadmaps. It provides illustrative examples from both governemnt and industrial practice. It is the first paper that presents road-mapping as a unified discipline."

Resumen:

"Research on Web searching is at an incipient stage. This aspect provides a unique opportunity to review the current state of research in the field, identify common trends, develop a methodological framework, and define terminology for future Web searching studies. In this article, the results from published studies of Web searching are reviewed to present the current state of research. The analysis of the limited Web searching studies available indicates that research methods and terminology are already diverging. A framework is proposed for future studies that will facilitate comparison of results. The advantages of such a framework are presented, and the implications for the design of Web information retrieval systems studies are discussed. Additionally, the searching characteristics of Web users are compared and contrasted with users of traditional information retrieval and online public access systems to discover if there is a need for more studies that focus predominantly or exclusively on Web searching. The comparison indicates that Web searching differs from searching in other environments."
