Health claims and consumer skepticism: The influencing effects of information type, sponsor reputation, and information channel
… interaction between the credibility of a set of information and consumers' skepticism toward a health claim nestled within that information set. Two research streams posit different types of consumer behavior. One stream of research suggests that consumers respond with skepticism to health …

Essays on Macroeconomic Shocks and the Business Cycle
… The effect that would prevail under symmetric information between the central bank and the private sector, and the `information channel'. Using a stylized model, we demonstrate that the information channel weakens the response of monetary shocks because a monetary contraction can signal …

Gatekeeping in agriculture publications: agriculture editors' uses of information sources and channels
… trade publications, turning to these sources for information that is used to make decisions in their production management, in turn affecting the entire multi-billion dollar industry in the United States. Editors of these trade publications act as gatekeepers of the information that is published, …

ms-Scale temporal coding in the thalamus predicted by whisker dispersive vibrational transduction
Whether stimulus information is encoded in the whisker system has been a question of debate. Considering the remarkable temporal precision in the whisker system with spike timing as small as 10μs, there is potential for ultrahigh capacity information channel in kb/s. To study temporal structures in …

Eustressed or Distressed? Combining Physiology with Observation in Stress Studies
… of a physiological and an observational information channel. The method enables the quantification of aroused emotional states and their disambiguation into positive or negative instances. The physiological channel targets sympathetic responses and is materialized as a perspiratory signal …

Slow frequency and time hopping in wireless communication
… We find, for the finite-state block-fading channel model, that when the receiver (but not the transmitter) has perfect side information on the channel state, diversity can only improve performance. In the absence of such side information, channel capacity decreases with diversity because of …

Multi-signal gesture recognition using body and hand poses
… gesture recognition system that integrates information from body and hand poses. Unlike previous approaches to gesture recognition, which concentrated mainly on making it a signal signal, our system allows a richer gesture vocabulary and more natural human-computer interaction. The system …

Adaptive MMSE multiuser receivers in MIMO OFDM wireless communication systems
… that is robust against slow and fast fading channel scenarios, in comparison to the conventional individual parameter estimation by E. Teletar in his famous paper of 1999. Implementing the Adaptive MMSE Receivers in MIMO OFDM systems which I refer to (AMUD MIMO OFDM), combines the adaptive …

Artificial Language Evolution on a Dynamical Interaction Network
… between the agents' hypothesis space and an information channel. We introduce a new ""language game"" which we call the classification game. We show that the population, through playing the classification game, converges to a representation which is simple, but not too simple, by balancing …
