This article addresses the question of understanding more about networked universities by looking at open source software developers working in academic contexts. It sketches their identities and work as an emerging professional community that both relies upon and develops digitally mediated networks and contributes to the progress of academic…

The "cyberinfrastucture" is a broad informational network that entails connections to real-time data sensors as well as tools that permit visualization and other forms of analysis, and that facilitates access to vast scientific databases. This multifaceted network, already a major boon to scientific discovery, now shows exceptional promise in…

Increasing instructor-student interactions and improving support personnel interventions with students positively affects their academic performance, retention, and graduation rates. This article discusses the Grade Performance Status (GPS) which is Northern Arizona University's new online, academic early alert tool for increasing instructor…

The nature of the multiuser object oriented (MOO) environment lends itself to flexible and rich interactive collaboration space providing interactive discussion, mail, mailing list, and news features to its virtual denizens. EdMOO (HREF1) was created in mid-1995 as an environment for teachers to experience the text based virtual reality…

Multicasting is a necessity for a broadband metro-area-network; however security problems exist with current multicast protocols. A stateful multicast access control mechanism, based on MAPE, is proposed. The architecture of MAPE is discussed, as well as the states maintained and messages exchanged. The scheme is flexible and scalable. (Author/AEF)

Integrated distributed learning environments (IDLEs) have emerged with the Internet and the World Wide Web. They are primarily based on a collaborative learning instructional paradigm rather than the self-instructional model of multimedia authoring systems. As such, they make extensive use of the asynchronous and synchronous collaborative tools…

Discusses the concept of the intranet, comparing and contrasting it with groupware, and presents an argument for its value based on technical and information management considerations. Presents an intranet development project for an academic organization and describes a portable, user-centered and team-based methodology for the design and…

Presents an overview of the security architecture of the IP multimedia core network subsystem (IMS) of the third generation mobile system, known in Europe as UMTS. Discusses IMS security requirements; IMS security architecture; authentication between IMS user and home network; integrity and confidentiality for IMS signalling; and future aspects of…

Reports on one of the first projects in the United Kingdom which used the Internet to link schools with their local career service. Results of evaluations by staff and pupils in four secondary schools are discussed in terms of design features, access and communication issues, and further recommendations for development. (Author/AEF)

With respect to the design of cooperative systems, issues related to the fundamental communication channels, sociotechnical factors, and task characteristics associated with collaborative work situations are reviewed. Research strategies incorporating theory-motivated design, ethnographic methods, and controlled testing methods are discussed as a…

This paper proposes a user-centered framework for intranet design that is based on an understanding of people, their typical problems, information behaviors, and situated contexts. It is argued that by adopting such an approach, intranets can be designed which facilitate organizational information access and use. The first section of the paper…

Reports on the results of a study of a community computing system, Prairienet. Examines characteristics of users and the extent to which Prairienet is serving its purpose as a community resource for networked communication and information access, through the analysis of usage patterns and logs. (Author/AEF)

This paper explores the viability of a new approach to intranet design, one that is based on an understanding of the organizational information environment and user information behavior. The approach was used by 11 project teams of graduate students to develop intranet designs for local organizations. The workbooks used by the project teams were…

Explores capabilities of extranets (collaborative information networks between partner institutions) from the perspective of the school and university environment. Introduces distinctive features. Presents strategies and techniques for facilitating the extranet design and implementation process and delineates tactics for safeguarding extranets…

Suggests a new infrastructure--the digital plant--for supporting flexible Web campus environments. Describes four categories which make up the infrastructure: personal communication tools and applications; network of networks for the Web campus; dedicated servers and software applications; software applications and services from external…
