Professor Roberto Serrano, who is the Harrison S. Kravis University Professor of Economics at Brown University, has detected a massive fraud in one of the classes he teaches, ECON 1170, an advanced undergraduate course in mathematical economics. He has conclusive evidence that at least 50 students cheated on the March midterm exam, making it the biggest known scandal at Brown and in the entire Ivy League 'Academic integrity is a value worth defending. The faculty cannot be left on its own in a battle that is decisive if we want to preserve the future of higher education,' explains the 61-year-old professor ' (El Pais) It was a closed book take-home exam; the problems were designed to test the student's ability but proved doable by an AI. After Serrano changed the final from take-home to in-person about half the students who had gotten perfect scores on the midterm chose not to take the final. The existence of AI, like the earlier problem of students buying papers online, reduces the ability of teachers to test their students but does not eliminate it, is inconvenient but not catastrophic. It makes some kinds of testing more difficult but not impossible; Serrano could have asked students whose midterms were suspiciously good to explain some of their answers and failed any obviously unable to do so. That would have been additional work for him and, judging by the article, not a policy Brown would have endorsed. Unwilling or unable to do that that he can base his future grading on work done in-person and adequately monitored....
'I've been interested in economics, economic impacts, and related social issues for a long time,' says Zhang, who majored in mathematical economics as an undergraduate. 'I wanted to apply my math skills to see how we could improve policies and their effects.' Zhang is interested in how to improve conditions for workers. She believes it's important to build relationships with policymakers, focusing on an evidence-driven approach to policy, while always remembering to center those the policies may affect. 'We have to remember the people whose lives are impacted by business operations and legislation,' she says. Zhang began investigating employee productivity, artificial intelligence, and related economic and labor market phenomena early in her time as a doctoral student, collaborating frequently with fellow PhD students in the department. A collaboration with economics doctoral student Shakked Noy yielded the 2023 study investigating ChatGPT as a tool to improve productivity. Their research found it substantially increased workers' productivity on writing tasks, most so for workers who initially performed the worst on the tasks....
âÂÂWho are you?â may well be the worldâÂÂs most frequently asked question. On a website, in a nightclub, at an airport, or in front of a bank counter, everyone wants us to prove that we are who we say we are....
Something is happening in Midtown Atlanta. Georgia TechâÂÂs city-centered campus has become one of the nationâÂÂs leading destinations for corporate research centers. Over the last decade, Tech Square, the eight-square-block area in Midtown designed to facilitate private and public research ventures, has attracted the corporate research centers of 12 Fortune 500 companies, including AT&T, Panasonic, and Coca-Cola, as well as hundreds of small technology startups. And just recently, NCR, one of the largest U.S. electronics companies, moved its global headquarters from the suburbs to Tech Square, bringing along 3,600 employees....
