Improvements in communications technology enable consumers to receive information through diverse channels. In the case of avian influenza, information repeated by the mass media socially amplifies the consumer awareness of risks. Facing indeterminate risks, consumers may feel anxious and increase their risk perception. When consumers trust the information published by the media, their uncertainty toward avian influenza may decrease. Consumers might take some actions to reduce risk. Therefore, this study focuses on relationships among trust in messages, risk perception and risk reduction preferences. This study administered 525 random samples and consumer survey questionnaires in different city of Taiwan in 2007. Through statistical analysis, the results demonstrate: (1) the higher the trust consumers have in messages about avian influenza, the lower their risk perceptions are; (2) the higher the consumers’ risk perceptions are and, therefore, the higher their desired level of risk reductive, the more likely they are to accept risk reduction strategies; (3) consumer attributes such as age, education level, and marital status correlate with significant differences in risk perception and risk reduction preferences acceptance. Gender has significant differences only in risk reduction preferences and not in risk perception.

The main purpose in this study was to examine the correlations between knowledge-sharing motivation, willingness, and behavior of volunteers and paid staff in different types of social welfare nonprofit organizations. Statistical analysis of empirical data from 375 participants' questionnaires revealed the following results. Only one of the hygiene factors, extrinsic motivation, was found to be unrelated to willingness to share knowledge. All other hygiene factors were significantly related to knowledge-sharing willingness behavior, and the intrinsic motivation factor had the strongest influence on knowledge-sharing willingness and behavior.
