LINCOLN, Neb. (AP) — The chancellor of the University of Nebraska-Lincoln is hoping to see the institution join others in adding a chief diversity officer to its administrative cabinet.

Chancellor Harvey Perlman’s call follows several racially-charged incidents on the university’s campus last year. That included a student using racial slurs a student senate meeting, another slur scrawled on a campus sidewalk and an ethnically insensitive homecoming skit in which students wore sombreros.

One study says more than 30 colleges and universities in the past five years have created an administrative position dedicated to fostering diversity and inclusion on campus.
