BACKGROUND Norovirus is a leading cause of gastroenteritis episodes and outbreaks in US military deployments, but estimates of endemic disease burden among military personnel in garrison are lacking. METHODS Diagnostic codes from gastroenteritis-associated medical encounters of active duty military personnel and their beneficiaries from July 1998-June 2011 were obtained from the Armed Forces ...

Purpose – To provide an empirical analysis of what influences police use of field citations (tickets) against citizens in nontraffic and traffic encounters. Design/methodology/approach – The research was conducted using systematic social observations of police-citizen encounters in Cincinnati, Ohio, from April 1997 to 1998. Multiple logistic regression models were used to examine the effects of...

We present a new approach to testing multi-UAV conflict resolution algorithms. We have formulated the problem as a multi-objective search problem, with two objectives: finding air traffic encounters that (1) are able to reveal faults in conflict resolution algorithms, and (2) are likely to happen in the real world. Our method uses agent-based simulation and multiobjective search to automaticall...
