UAMS Chancellor attacks with balanced budget
The University of Arkansas for Medical Sciences had an operating loss of $27.8 million in the first six months of its current fiscal year, a dramatic downturn from an $8.5 million operating gain during the same period a year earlier. Dr. Dan Rahn, the chancellor of UAMS, said he has a multi-point strategy to increase revenue and slash expenses that should generate about $40 million for UAMS during the next 18 months. "We're dealing with some fundamental changes," Rahn told Arkansas Business last week during an interview in his office at the UAMS Medical Center. "The financial model that we've relied upon for the past decades is changing, and we're going to have to change."

Ex-Barclays bankers charger with libor rigging
Prosecutors have charged three former Barclays bankers in connection with the rigging of global interest rates. The U.K.'s Serious Fraud Office, which prosecutes complex cases of fraud, said Monday that it's started criminal proceedings against Peter Charles Johnson, Jonathan James Mathew and Stylianos Contogoulas in connection with manipulating the London interbank offered rate, or Libor. All three have been charged with conspiring to defraud between June 2005 and August 2007. The scandal began in the middle of 2012, when Barclays (BCS) admitted to manipulating Libor, which together with related rates is used as a benchmark for trillions of dollars of financial products around the world.

Samsung sues Dyson for calling it a patent copycat
Given its miserable track record in patent battles with Apple (AAPL), Samsung's legal team must have taken great solace in Dyson Ltd's decision to drop the patent infringement suit it filed against the company in September. At issue was the steering mechanism in the "Motion Sync" vacuum cleaner that Samsung introduced at a Berlin consumer electronics show last summer. Sir James Dyson declared it a "cynical rip-off" of a patented feature in Dyson's DC cylinder vacuums. Samsung had documentation to show it had been working its steering mechanism for more than a year, and the Dyson suit was dismissed on Nov. 21, 2013 -- the same day a California jury ordered Samsung to pay Apple another $290 million for iPhone patent infringements.

Want to see a doctor? Be prepared to wait!
Need to see a doctor, but it's not an emergency? You might have to wait a few weeks, though it depends on where you live. Dallas residents may be able to get an appointment to see a family physician in five days, on average, but Bostonians might have to flip two months ahead on the calendar to mark the first available appointment for new patients. Merritt Hawkins, a physician recruitment firm, surveyed the average time it takes for new patients to see a doctor for non-emergency issues in five specialties in 15 large metropolitan areas in 2013. The specialties were cardiology, dermatology, obstetrics/gynecology, orthopedic surgery and family practice.
