The current version of the IP protocol, IPv4, is the most widely used protocol in computer networks. This article describes mechanisms that can be used to facilitate the transition to the new version of the IP protocol, IPv6, and examines usability, usefulness and manageability. Describes how some of these mechanisms were applied to the Greek…

Delivering content to distant users located in dispersed networks, separated by firewalls and different web domains requires extensive customization and integration. This article outlines some of the problems of implementing the Sharable Content Object Reference Model (SCORM) in the Marine Corps' Distance Learning System (MarineNet) and extends…

Describes the layered model of Open Systems Interconnection (OSI); summarizes the three upper and lower layers; and discusses data communications standards associated with specific layers. Architectural concepts are explored, including hierarchy and abstraction, levels of dialogue, internetworking, and end-to-end communication. OSI is compared…

Describes Project THEORIA, which was developed at Carnegie Mellon University to design interactive simulation environments for testing hypotheses and theories of the arts and human morals. Three projects in various stages of design and development are described: (1) "A Right to Die?; (2) "Art or Forgery?"; and (3) "Birth or…

Reviews the development process of the TouchSource authoring system, which has been designed for use in developing touchscreen information directories using interactive videodisc. Topics discussed include authoring languages; the compatibility of interactive videodisc systems; hardware considerations; menu creation and design; database functions;…

Discusses the issues influencing the design, implementation, and promotion of the Towers Perrin in-house text retrieval system. The discussion of factors influencing system design includes the organizational culture, the existing computer and communications network, and the availability of text retrieval software. Suggestions for in-house systems…

These two articles discuss the contributions of behavioral and cognitive psychology to the design of computer-based instruction (CBI) and describe an integrated meta-model for use with instructional systems design (ISD) called ROPES + (Retrieving, Orienting, Presenting, Encoding, and Sequencing). Highlights include motivation, information…

Describes study that was conducted to investigate the relationship between locus of control and user attitude toward computer based information systems (CBIS) used at work. The impact of user involvement is examined, the hypotheses tested are described, and implications for introducing CBIS into organizations are discussed. (14 references) (LRW)

The Structured Sound Function (SSF) Model is proposed as a method for adding audio to educational computer programs. Topics include the background of the SSF Model; educational hypermedia computing; the two approaches (structure-before-function and function-before-structure) of applying the SSF Model; and recent applications. (57 references)…

Discusses a user interface that simplifies NF Squared (non-first-normal-form) relational query formulation in which query specification remains compact and straightforward. This interface allows for nesting and general hierarchical structures and restructuring which provides for more effective retrieval and query formulation. (Author/JKP)

Discusses computer software and system design in the information industry and provides an annotated bibliography of 31 resources that address the issue of design. Highlights include competition, color use, hardware and presentation design, content and packaging, screen design, graphics, and interactive multimedia. A sidebar reviews and rates seven…

Examines potential solutions to the problem of personal computer cabling and configuration and serial port performance, namely "FireWire" (P1394) and "Universal Serial Bus" (USB). Discusses interface design, technical capabilities, user friendliness, compatibility, costs, and future perspectives. (AEF)

Proposes a unifying framework based on speech act theory, which reconciliates the representation and communication roles of information systems. Focuses on how communication can be modeled by means of discourses, which are viewed as sequences of events; discusses implications for future research. (Author/AEF)

Describes a study that was conducted to determine how error patterns and a clinical approach to assessing third grade students' mathematical knowledge interrelate to design a computer diagnostic system for subtraction. Error patterns are examined, and computer diagnostic systems and analytical testing are discussed. (34 references) (LRW)

Reports on a pilot study in which a proposed design model was developed to characterize intergroup communication among designers, developers, and users. Design roles, themes, and networks based on two histories of design situations are described for several design phases; and future work is suggested. (24 references) (LRW)
