Motivation for Protecting Selfish Vehicles' Location Privacy in Vehicular Networks

Abstract: Location privacy is an important issue in vehicular networks since knowledge of a vehicle's location can result in leakage of sensitive information. A way to protect vehicles' location privacy is to have them change their pseudonyms in predetermined regions known as mix zones. However, selfish vehicles may not change their pseudonyms because of limited resources (such as pseudonyms and bandwidth). This could jeopardize the location privacy of those vehicles that are in need of changing their pseudonyms. To encourage vehicles to cooperate in changing their pseudonyms, we propose a method called Motivation for Protecting Selfish Vehicles' Location Privacy (MPSVLP). In MPSVLP, vehicles can form a mix zone dynamically when their pseudonyms are close to expiration and can also earn reputation “credit” by implementing a pseudonym change. The simulations show that MPSVLP motivates more selfish vehicles to cooperate with each other while maintaining a high level of location privacy. In addition, MPSVLP can reduce communication overhead in comparison with the existing methods.

Effects of chitosan nanoparticles on survival, growth and meat quality of tilapia, Oreochromis nilotica

Abstract: To evaluate the effect of dietary chitosan and chitosan nanoparticles on survival rate, growth performance and meat quality of tilapia (Oreochromis nilotica) under laboratory conditions, fish were fed with these compounds both at 5.0 g kg(-1) of diet for a period of 60 days. The addition of chitosan nanoparticles (T-2) significantly improved (P < 0.05) final weight, daily weight gain (DWG) and feed conversion ratio (FCR) compared to fish fed chitosan containing diet (T-1) and basal diet (control). However, there were no significant differences in final weight, DWG and FCR between T-1 and control. As for crude fat, the lowest content (P < 0.05) was found in T-2. In addition, a significant increase (P < 0.05) in inosinic acid content was found in T-2 compared with T-1 and control. These results indicate that dietary chitosan nanoparticles supplementation improved the growth performance and meat quality status of tilapia.

The Contribution of Local Cuisine to Destination Attractiveness: An Analysis Involving Chinese Tourists' Heterogeneous Preferences

Abstract: A model incorporating Chinese tourists' heterogeneous preferences of local cuisine, perceptions of local cuisine attractiveness, and destination attractiveness was investigated using the survey data collected from two cities in China and partial least-squares structural equation modeling. Local cuisine attractiveness significantly contributes to tourists' perceptions of destination attractiveness. Among the three dimensions that profile tourists' heterogeneous preferences of local cuisine, tourists' involvement and knowledge of local cuisine have significant correlations with their perceptions of local cuisine and the destination, while past experience of local cuisine does not have influence. The findings have implications for developing and promoting local cuisine-related tourism products to Chinese tourists.
