Research shows that urban residents obtain information on food safety through TV programs and newspaper and there are a great of problems in food. 55. 43% of the consumers consider that the name-brand livestock and poultry products are safer than ordinary livestock and poultry products. The result of the model shows that food safety awareness about the name-brand livestock and poultry products has dramatically affected urban residents' purchasing decisions of livestock and poultry products. The biggest effect is on the brand of eggs and pork as the major daily consumer goods. Furthermore,income and prices are still the determining factors affecting the consumers' purchasing decisions of the name-brand livestock and poultry products. And the features of livestock and poultry products( nutrition,taste) significantly affect the name-brand livestock and poultry products.展开更多

Data for this study were collected through the distribution of 247 well-structured questionnaires. Likert Scale was adopted for the analysis of the respondents. The results revealed that awareness is critically low. Though the respondents have concern for their environment in various degrees, majority dispose their e-waste alongside municipal wastes without knowing the implications. Awareness strategy was designed for sensitization campaign.展开更多

Wireless mesh network （WMN） as a relative static multi-hop wireless network which is extended from Ad-Hoc networks, has become one of the key technologies for providing increased network coverage of Internet infrastructures. This paper investigates the problem of enabling P2P file sharing in WMNs. A special chord algorithm--spiralchord is proposed to address the major problem in wireless file sharing system how to efficiently find resources currently available. Spiralchord put forward an identifier （ID） assignment technique based on spiral space-filling curve to integrate location-awareness with cross-layering. Location awareness aims at alleviating the mismatch of physical network topology and overlay network topology, and requires close-by IDs in logical ring of neighboring peers, while cross-layering aims at speeding up resource lookup operations, requires faraway IDs of neighboring peers. Spiralchord uses spiral curve to assign peers＇ IDs which meet the contradictory requirements of location-awareness and cross-layering. The simulation results show spiralchord is effective in reducing message overhead, and increasing lookup performance with respect to basic chord.展开更多
