Food Safety and Demand: Consumer Preferences for Imported Pork in Urban China

China’s transition into a developed economy is driving changes in consumer preferences and demand for foods. The objective of this study is to assess and measure consumers’ preferences for and attitudes toward imported pork in urban China. Estimated logit models based on a consumer survey conducted in 2008 reveal that individuals’ age, shopping location, and food safety concerns significantly influence their willingness to pay for U.S. pork. Factors affecting purchasing behavior of Western-style pork cuts versus traditional Chinese cuts are also evaluated. Consumers’ food safety concerns were linked to a previous lean-meat additive scare and a lack of confidence in the Chinese food inspection system.Consumer/Household Economics, Food Consumption/Nutrition/Food Safety, Livestock Production/Industries,

Relative periodic orbits in point vortex systems

We give a method to determine relative periodic orbits in point vortex systems: it consists mainly into perform a symplectic reduction on a fixed point submanifold in order to obtain a two-dimensional reduced phase space. The method is applied to point vortices systems on a sphere and on the plane, but works for other surfaces with isotropy (cylinder, ellipsoid, ...). The method permits also to determine some relative equilibria and heteroclinic cycles connecting these relative equilibria.Comment: 27 pages, 17 figure
