In the U.S. prison system, the prevalence of hepatitis C virus (HCV) infection is currently 10 times higher than the national average. And while new HCV treatment drugs are very effective, their high cost along with very limited healthcare budget in prisons impedes universal treatment in prisons. Now, new research in the INFORMS journal Operations Research, has identified new protocols that could substantially decrease HCV infection in the U.S. prison system. 

New research in the INFORMS journal Management Science took an in-depth look at 128 events of negative publicity tied to a celebrity endorser between 1988 and 2016. These events affected sponsors in 230 actual cases. What gives the research its punch is that it evaluated the effectiveness of company responses to celebrity endorsers’ misbehaviors using those companies’ daily abnormal stock returns. In other words, if a brand encountered a celebrity endorser crisis, as Nike did when Tiger Woods made news over his notorious marital problems, the study authors took into account the surrounding negative publicity’s impact on the company’s stock price.

INFORMS member, professor with the University of Buffalo and Buffalo Bills football fan Mark Karwan's research to outline a mathematical approach by which the NFL could potentially produce a materially fair and largely disparity-free schedule, has led to a three-year research grant with the NFL to provide year-round method development and schedule testing.
