Studies examining how culture shapes CMC usage patterns have become increasingly prominent. These studies consistently show that differences exist, but no clear, underlying explanation has been offered which can account for results across studies. Such a predictive pattern is needed in order to work toward understanding, and overcoming, difficulties in cross-cultural CMC-based collaborations on more than a case-by-case basis. In this thesis, I first use interviews to call out areas of collaboration which are particularly challenging to members of different cultures. I then utilize a vignette survey study to evaluate how one particular challenge , imposition management, which incorporates both media and culturally-bound variability, may be viewed.
