Hi Fran, 

We work with simulations and have experience in telematic simulations in which participants from all over the world interact. There' s plenty of research available. Take a look at Crookall, García-Carbonell, Watts' or my profile.

Also, visit Icons Project from University of Maryland. 

Hope it helps

 Hi Laura

Thanks for your response and info to follow up. I am familiar with simulation games as a pedagogical tool. The links seem to be mostly for the context of learning a language in order to communicate across cultures. This is an interesting dimension, but I am working on a project that is about intercultural interaction between those who speak English, but different Englishes (e.g. Canadian English, Chinese English etc). So the focus is the relationship between language and culture, and how deeply held different ways of being affect how we 'translate' each other, even when speaking apparently the same language. This is why I am not just focusing on communicative competence, but cultural 'competence' (for want of a better work) as well.

Yes, there are some. I'll give you a qualitative one: the interview of a German Magazine with a writer from Kenya on understanding Africa and refugees.

The interview is funny, surprising, inspiring.

And it's dialogue, not aggregared data and binary questions like the World Value Survey (WVS).

If we had four or five interviews like this one in every country we would face less war and conflicts.

I include a great English essay of the author (link).

Thank you Alexander - I have a copy of his book, but have not seen the interview before.
