Women in Job Market

Women are also underrepresented in the administration and this is because there are so few women full professors. In 1985, Regent Beryl Milbum produced a report blasting the University of Texas System administration for not encouraging Women. The University was rated among the lowest for the system. In a 1987 update, Milbum commended the progress that was made and called for even more improvement.

One of the positive results from her study was a System-wide program to inform. women of available administrative jobs.

College of Communication Associate Dean Patrica Witherspoon, said it is important that woman be flexible when it comes to relocating if they want to rise in the ranks.

Although a woman may face a chilly climate on campus, many times in order for her to succeed, she must rise above the problems around her and concentrate on her work.

Until women make up a greater percentage of the senior positions in the University and all academia, inequities will exist.

"Women need to spend their energies and time doing scholarly activities that are important here at the University." Spirduso said. "If they do that will be successful in this system.If they spend their time in little groups mourning the sexual discrimination that they think exists here, they are wasting valuable study time."

According to Spirduso, women need to __________. 查看材料

A.produce a report on sexual discrimination

B.call for further improvement in their working conditions

C.spend their energies and time fighting against sexual discrimination

D.spend more time and energy doing scholarly activities
