    '-~~---------------------, tr'lMf /tJ66 d-LLf 2003-04 UNIVERSITY OF MINNESOTA FEBRUARY 12,2004 FACULTY SENATE MINUTES: No.3 The third meeting of the Faculty Senate for 2003-04 was convened in 25 Mondale Hall, Minneapolis campus, on Thursday, February 12,2004, at 2:06 p.m. Coordinate campuses were linked by telephone. Checking or signing the roll as present were 116 voting faculty/academic professional members. Vice Chair Carol Wells presided. 1. FACULTY CONSULTATIVE COMMITTEE REPORT Professor Judith Martin, Chair of the Faculty Consultative Committee (FCC), said that the committee has been working on several issues. The first issue is the budget and the University's capital request. The committee has been working with the legislative liaisons about what needs to be done to secure this request. FCC has also started talking about issues for next year's budget request. The second issue is a proposed Regents policy on the commercialization of technology. It is important to have faculty input on this issue since pressure on the University increased with the approval of federal legislation. FCC is talking with the administration and Regents about how the process will work here. Since this is a complex issue, material has been posted on the web and a reminder will be sent to all senators tomorrow. Lastly, the committee has been watching a few bills in Congress that might have an impact on faculty work. First is the McKeon bill, which would limit tuition raises to that of inflation. FCC may send a message to its Congressional delegation on the topic. Second is a proposed Student Academic Bill of Rights.
