We investigate a dynamic advertising model where product quality is endogenous. In the differential game between single-product firms, there exists a parameter range where the low-quality firm uses a more efficient advertising technology and earns higher profits than the rival. Moreover, we show that equilibrium qualities are the same under duopoly, multiproduct monopoly and social planning, th...

Functionalism, as generally understood, is not included in DSM-III-R. It differs from somatization and hysteria. Analysis of cases of functional overlay indicates the presence of a fixed attitude--depending on body-image distortion, feelings of injustice toward the existing medicolegal methodology, social and economic impairment, anger against legal delays, and a conviction of the futility of t...

Thls paper poses the question: How does the representation of the body in virtual environments affect the mind? This article considers how virtual reality interfaces are evolving to progressively embody the user. The effect of embodiment on the sensation of physical presence, social presence, and self presence in virtual environments is discussed. The effect of avatar representation on body ima...

This paper examines a steerable projection system, the everywhere displays projector (ED-projector), which transforms surfaces into interactive displays. In an ED-projector, the display image is directed onto a surface by a rotating mirror. Oblique projection distortion is removed by a computer-graphics reverse-distortion process and user interaction (pointing and clicking) is achieved by detec...

Manuscript under review. Please do not quote without permission. Information Distortion in Risky Decisions 2 Manuscript under review. Please do not quote without permission. ABSTRACT—Substantial evidence indicates that information is distorted during decision making. However, no studies have assessed the distortion of outcome and probability information in risky decisions or the effects of ambi...

Navigating in large geometric spaces-such as maps, social networks, or long documents-typically requires a sequence of pan and zoom actions. However, this strategy is often ineffective and cumbersome, especially when trying to study and compare several distant objects. We propose a new distortion technique that folds the intervening space to guarantee visibility of multiple focus regions. The f...
