Emory University in Atlanta announced Monday they will be moving commencement activities off campus, citing "concerns about safety and security."

"Please know that this decision was not taken lightly. It was made in close consultation with the Emory Police Department, security advisors, and other agencies — each of which advised against holding Commencement events on our campuses," Emory President Gregory Fenves wrote in a message to the university.

The commencement ceremonies will now be held in Duluth, about a half hour from campus, the university said.

On April 25, there were 28 people arrested, including 20 affiliated with Emory University, during a protest on campus, according to the school.

Columbia University announced Monday it will not hold a campuswide commencement ceremony on May 15 as originally scheduled.

Columbia will focus on the smaller, school-based ceremonies instead based on "input and feedback from student leaders," the school said.

"Our students emphasized that these smaller-scale, school-based celebrations are most meaningful to them and their families," the school said in a statement. "They are eager to cross the stage to applause and family pride and hear from their school’s invited guest speakers."

The smaller school ceremonies will begin on Friday. Columbia said it may hold "a festive event" on May 15 instead. Security concerns were among the reasons the larger ceremony was canceled.

One of the reasons Columbia said it had called in the New York Police Department last Tuesday was in order to make room for the schoolwide ceremony in the same location as the encampment.

UCLA Chancellor Gene Block announced Sunday that the university is taking several immediate steps to increase campus safety following protests that prompted the closure of the school last week.

Block said the newly created Office of Campus Safety will oversee the management of the UCLA Police Department and the Office of Emergency Management. The administrative vice chancellor was previously in charge of the agencies.

Rick Braziel, the former Sacramento chief of police, will head the new Office of Campus Safety, Block said. Braziel will report directly to Block.

Additionally, Block said he has created a formal advisory group of safety experts who will partner with Braziel, including U.C. Davis Police Chief Joh Farrow; Vickie Mays, professor of psychology and health policy and management at UCLA, and Jody Stiger, the U.C. Office of the President systemwide director of community safety.

"In the past week, our campus has been shaken by events that have disturbed this sense of safety and strained trust within our community," Block said in a statement Sunday. "In light of this, both UCLA and the UC Office of the President have committed to a thorough investigation of our security processes. But one thing is already clear: To best protect our community moving forward, urgent changes are needed in how we administer safety operations."
