Editorial Pointers

To put together this issue on collaborative technologies required a truly collaborative effort. The result, we contend, is an exceptional example of teamwork with 33 authors from around the world producing 16 articles that represent two special sections on the latest advancements in collaborative technologies, as well as the challenges and benefits of implementing them […]

News Track

Recently enacted U.S. counterterrorism legislation makes it easier for the federal government to track suspected terrorists by extending its reach into citizens’ private lives. The measure, called the Uniting and Strengthening America Act, allows investigators easy permission to look at parts of an email application that show recipient and sender fields. It also allows the […]

Forum

In their column "An Introduction to Software Stability" ("Thinking Objectively," Sept. 2001), Fayad and Altman briefly suggest that more complex (and granular) models more accurately describe problems, and that the model (and the consequent software) becomes more durable/stable. There is also a distinction between modeling the problem and modeling the solution; in the first example […]

Collaborative Virtual Design Environments: Introduction

Computer-generated animated and enhanced movies and training simulations are now commonplace because of an exponential increase in cost-effective computer power and software robustness. Today, pilots and astronauts routinely train and practice normal and emergency scenarios much as they would in a real vehicle in an operational environment. As entertainment-seeking consumers, we regularly find ourselves viewing movies, TV, and games containing imaginary dinosaurs, aircraft dogfights, monsters, and voyages to other planets and galaxies.

Design Engineering in Virtual Environments

The current Space Shuttle Orbital Maneuvering System (OMS) and the related Reaction Control System (RCS) make use of hydrazine as a propellant. Hydrazine, while high in energy content, is both corrosive and poisonous. As a result, its use in the OMS/RCS dictates that extreme caution be used in both the initial charging of the systems […]

Expert Finding For Collaborative Virtual Environments

While computer-supported collaborative virtual environments have been successfully applied to revolutionize distance learning, distributed design, and collaborative analysis and planning (see Ragusa and Bochenek’s introduction to this section), a fundamental challenge of these systems is establishing the right teams of individuals during interactive problem solving for consultation, coordination, or collaboration. Motivated by our use of […]

A Shared Virtual Environment For Exploring and Designing Molecules

Project ScienceSpace was conceived as an effort to design and evaluate immersive virtual environments for science education from the elementary school through the early years of college (see www.vmasc.odu.edu/vetl/html/ScienceSpace/Sciencepace.html and www.virtual.gmu.edu). PaulingWorld is the part of the ScienceSpace Project that deals with molecular display and manipulation. A feature that differentiates PaulingWorld from other ScienceSpace applications […]
Research and Advances Global Applications of Collaborative Technology

Global Applications of Collaborative Technology: Introduction

Collaborative technologies, sometimes referred to as "groupware applications" given their deployment to support groups of individuals engaging in collaborative tasks, have developed rapidly in the last few years. Much of this expansion has been fueled by the dramatic increases in Internet penetration in societies around the world, making it possible for globally distributed teams to work on projects. We see these technologies being applied in a variety of ways, ranging from organizational communication and decision making to distributed software inspections and development to virtual education initiatives. The systems themselves include an array of technologies that may include video- and audioconferencing, shared calendaring, (digital) document management systems, text-based group support systems, and many more.

Nonconsensual Negotiation in Distributed Collaboration

Distributed projects are not only more difficult to manage, but also involve problems never considered for traditional methodologies on single-site projects. The collaboration project described here involves the development and writing of a multipartner European Union grant proposal. The scope of the proposal was initially agreed upon by most partners in a brief face-to-face meeting. […]

Risks of National Identity Cards

In the wake of September 11th, the concept of a national identity (NID) card system has been getting considerable play, largely promoted by persons who might gain financially or politically from its implementation, or by individuals who simply do not understand the complex implications of such a plan. Authentic unique identifiers do have some potentially […]
