Those people working with Chinese, Chinese-American, and/or Latino web users may take interest in a couple of recent studies that connect Geert Hofstede’s cultural dimensions to multi-ethnic web usability among these groups:
Usability for Latinos - - http://www.filippsapienza.com/blog1/2010/02/03/usability-for-latinos/
Cultural Dimensions of Chinese and Chinese-American Websites - - http://www.filippsapienza.com/blog1/2010/02/03/chiamer/
The studies are presented in English, Chinese, and Spanish and are entirely free. Feedback is of course appreciated.
