Short-term scholar is by definition someone who is coming to Michigan State University (MSU) for a period not to exceed six months. For a scholar who is subject to it, the 12-month bar does not apply when he/she comes for short-term visits. Still a short-term scholar must satisfy all the requirements pertaining to all Visiting Scholars (including proof of adequate financial support). Also, if the visit is for a few weeks, such a scholar should check with the immigration officer in his/her country to see whether one can come on a tourist visa so that there is no need to complete the J-1 Scholar DS-2019 Request form. Any period longer than a few weeks would require the DS-2019 Request form which solicits information on what is required to be accepted as a Visiting Scholar: http://www.oiss.msu.edu/documents/scholars/DS2019_Scholar_Initial.pdf (http://www.oiss.msu.edu/documents/scholars/DS2019_Scholar_Initial.pdf).
Regardless of whether they come for a few weeks or a longer period, advance communication with the African Studies Center and any other MSU academic units of interest must be made and the agreement to come obtained.
