      Empirical research in operations management has increased steadily over the last 20 years. In this paper, we discuss why this is good for our field and offer some comments on the qualities we admire in an empirical operations ...
    • Why Is It Hard to Obtain a Dichotomy for Consistent Query Answering? 
      Fontaine, Gaëlle (ACM, 2015)
      A database may for various reasons become inconsistent with respect to a given set of integrity constraints. In the late 1990s, the formal approach of consistent query answering was proposed in order to query such databases. ...
