4 pages., Via online journal., Transformation process to Audience-centered Communication Theory is introduced, as well as the basic idea of the theory in China. It is believed that using Audience-centered Communication theory can help to consolidate the theoretical basis of participatory agricultural extension. The communication essence of agricultural extension activity is studied, which is spreaders send information to farmers; then, farmers filter and process the information, transform it into their own experiences and feed back on time. Internet logical relationship between audience-centered communication and participatory agricultural extension is studied. Effects of Audience-centered Communication Theory on participatory agricultural extension are analyzed. One is that the Audience-centered Communication Theory defines the guidance and implementation basis of agricultural extension activities; the other is that bringing Audience-centered Communication Theory into agricultural extension research can help to expend the agricultural extension. Several enlightenments of the theory to participatory agricultural extension are obtained. Firstly, take audience as the orientation and focus on the needs of the audience. Secondly, advocate the participatory approach of process; and emphasize the importance of internal audience participation. Thirdly, establish two-way interaction mechanism; and make the promoters understand the implementation and performance status on time.
12 pages., via online journal, We examined how information from multiple communication channels can inform social norms about local food purchasing. The concept of social exposure was used as a guide. Social exposure articulates how information in social, symbolic, and physical environments contributes to normative perceptions. Data was collected from a sample in Wisconsin. Results indicated that information from communication channels representing symbolic, social, and physical environments all contributed to normative perceptions. We also found that for individuals who frequent farmers’ markets, information from some communication channels was relatively less strongly associated with injunctive norms. It may be that when first-hand, experiential information is available to inform norms, individuals rely less on information available through other communication channels. Future work might further explore how farmers’ markets foster information sharing in communities, as such information may contribute to normative perceptions.
