Presents an activity that begins with a discussion that leads into the rationale behind the techniques used in the Search for Extraterrestrial Intelligence (SETI) program. Students decode a message intended for extraterrestrials and consider a number of topics related to the possible existence of extraterrestrials. (DDR)

Describes information metering technology as a method that information providers use to provide information collections to users in encrypted form and charge them only for the parts actually used. Discusses how two current information metering systems (Wave Systems Corporation and CD-MAX) operate, the institutions using their systems, and the…

The accuracy of a subject-generated coding system for anonymous questionnaire responses was studied using a collateral, anonymous sticker identification system as a standard. Results with 745 middle school students who took pretests and posttests show the effectiveness of the subject-generated coding system. (SLD)

Describes the use of an outside graphic design firm to redesign the Yale University Library (New Haven, CT) Web site. Topics include division of labor; design principles and technical requirements; related Web sites at Yale; usability testing; coding that conformed to library standards; ease of use; and communication between the design firm and…

Reports results from a national study into the perceived variation reported by health information managers related to the relevance-efficiency trade-offs of information classification across regions and practice settings. Findings suggest that due to major regional variation, stringent national information standards may be counterproductive for…

Ten adults with mild mental retardation used color-coded food photographs and meal code cards to plan nutritionally balanced meals. Subjects spent an average of nine minutes to plan three meals. Errors, which were primarily omissions, occurred mostly in food groups requiring four servings daily. (JDD)

Discusses common error-detecting identification codes using linear algebra terminology to provide an interesting application of algebra. Presents examples from the International Standard Book Number, the Universal Product Code, bank identification numbers, and the ZIP code bar code. (YP)

Provides an overview of research on notetaking and two related learning strategies: outlining and concept maps. Examines the potential effectiveness of approaches to aid learning in encoding new information and current uses in interactive multimedia instruction. Offers suggestions for incorporating these strategies into future designs. (Author/AEF)

Discusses the importance of computer security and considers criminal, national security, and personal privacy threats posed by security breakdown. Several examples are given, including incidents involving computer viruses. Objectives, content, instructional strategies, resources, and a sample examination for an experimental undergraduate computer…

Presents a public-key cryptosystem application to introduce students to several topics in discrete mathematics. A computer algorithms using recursive methods is presented to solve a problem in which one person wants to send a coded message to a second person while keeping the message secret from a third person. (MDH)

Drummond and Hopper's article in this issue, "Back Channels Revisited," is argued to have decontextualized Jefferson's acknowledgement token phenomenon. The need for careful coding protocols for research on conversational practices is discussed. (eight references) (LB)

It is suggested that the conventional coding procedures of experimental social psychology miss critical (identifying, defining, or constitutive) features of conversation analysis' phenomena because the procedures present the analyst with two different sets of entities; i.e., they are incommensurable. (20 references) (LB)

Introduces computerized coding procedure that rates words and utterances in terms of emotion, cognition, and contract, as well as contingency method of analyzing verbal interactions. Rating procedure and contingency correlation analyses using transcripts of sessions conducted by three therapists with one client found that therapists' utterances…

Discusses computer conferencing in higher education, presents a community of inquiry model that includes benefits of computer conferencing, and discusses social presence, defined as the ability of learners to project themselves socially and affectively into a community of inquiry. Topics include teacher immediacy, coding, and content analysis of…

Purpose: To describe the open-source solution developed by Culturenet Cymru, for the Welsh Books Council, for presenting digitised books and other printed material online. Design/methodology/approach: The challenges faced in the implementation of a pilot e-book collection of nine out-of-print books is described. Findings: The adoption of a number…
