    • Gender Disparity in Third World Technological, Social, and Economic Development 

      Akubue, Anthony I. (Epsilon Pi Tau and Virginia Tech Libraries, 2001)
      Despite their seemingly intractable problems, Third World countries have made remarkable progress in improving the well-being of their people in recent decades… A troubling concern, however, is the notion that gains from ...
    • Saving a river: Why do local governments matter? 

      Rola, Agnes C.; Tabien, C. (College, Laguna, Philippines: University of the Philippines Los Baños. School of Environmental Science and Management, 2001)

    • Making design work: Sustainability, Product Design and Social Equity 

      Walker, Stuart; Dorsa, Edward A. (Kluwer, 2001)
      This paper discusses the relationship between the product designer, sustainability and the creation of good quality work within the manufacturing sector. When the principles of sustainability are applied to the nature of ...
    • Usability Evaluation in Virtual Environments: Classification and Comparison of Methods 

      Bowman, Douglas A.; Gabbard, Joseph L.; Hix, Deborah (Department of Computer Science, Virginia Polytechnic Institute & State University, 2001), TR-01-17
      Virtual environments (VEs) are a relatively new type of human-computer interface in which users perceive and act in a three-dimensional world. The designers of such systems cannot rely solely on design guidelines for ...
    • Pinch Keyboard: Natural Text Input for Immersive Virtual Environments
