Information consumption in China occurs in a rapidly shifting social and political environment. Understanding this group of information consumers is likely to play an important role in business and political decision making globally for the foreseeable future. Ratings of the importance of the dimensions of information quality and the way in which these ratings have shifted over time shed light on the beliefs of this group of information consumers. This study reports the results of a nonpanel longitudinal study involving two surveys conducted in China over a five year period examining information consumer ratings of the importance of the dimensions of information quality. Results show that Chinese information consumers rate the information quality dimensions of believability, reputation, and value-added as less important at the end of the five year period than at the beginning and rate representational consistency and concise representation as more important at the end of the five year period than at the beginning.

Gesture in multimodal researches has been studied widely recently, and how gesture interacts with speech in communication is the focus in most researches. Some hypotheses or models about production and interaction between gesture and speech are introduced and compared in this paper. We find that it is generally agreed that speech production mechanism can be explained based on Levelt's Model; while there is no consistency about gesture production and the interaction between gesture and speech. Most of theories argue that gesture stems from the visual-spatial images in working memory; some models approve of the interactive relationship while others consider no interaction between gesture and speech. Further research will be made in the areas of theoretical and applicative aspects.
