In a situation where different cultures with different traditions are being observed, do I say:<br/><br/>We're conducting a research to evaluate different traditions <i><b>amongst</b></i> the different cultures based on common ethical standards.<br/><br/>Or,<br/><br/>We're conducting a research to evaluate different traditions <i><b>accross</b></i> the different cultures based on common ethical standards.<br/><br/>Are they both correct? How does the meaning differ changing (switching?) between the two words?<br/><br/>Thank you for your time.
