The University of Virginia will officially cut its ties with the Semester at Sea study abroad program by 2016, ending an academic sponsorship overshadowed by a UVa student’s death. … “As often happens with sponsorships, there comes a time to explore other opportunities,” Semester at Sea spokeswoman Lauren Judge said. “It was a mutual agreement.”  University spokesman Anthony Paul de Bruyn sent a prepared statement acknowledging both the school’s role as sponsor over the years and that the relationship with Semester at Sea is ending.
