Hi Sonia
As (Cite Contribution) mentioned you could go through hofstede's site, I felt the page below to be useful as well.
"http://www.geert-hofstede.com/hofstede_dimensions.php"
You may want to also look at other models of intercultural management/ communication. Trompenars etc....It would provide your study more universality.
Do let me know if you need any further inputs.
Regards,
Rohan
