¢ Lawrence’s proposed domestic partnership registry is getting some national attention. Most recently, it’s been posted on the Web site Gay.com._A proposed Lawrence, Kan., ordinance that would allow unmarried heterosexual and same-sex couples to register their partnerships would not violate the 2005 amendment to the Kansas Constitution banning same-sex marriage, Attorney General Paul Morrison wrote in an opinion made public Friday._¢ Mark Hirschey, a KU business professor an acquaintance of Warren Buffett, sounds off on the billionnaire’s acquisition of Burlington Northern Santa Fe in an article in Business Week._Buffett’s Burlington stake is “not the sort of move where you’ll see huge rates of return,” says Mark Hirschey, a professor at the University of Kansas School of Business.
