This paper describes a problem domain that lends itself to mixed initiative i n teraction. The domain is traded control with an autonomous robot. Traded control is a situation in which a h uman wants to control a robot during part of a task and the robot is autonomous during other parts of a task. A signiicant problem in traded control situations is that(More)

Use of individual-based models (IBMs) has been expanding in both theoretical and applied ecology. IBMs include details at the level of individuals that may lead to different conclusions from aggregated modeling methods. There has been essentially no guidance available on how to most effectively manage populations when the underlying dynamics are best(More)
OBJECTIVE To investigate the roles of inflammation and a cholesteryl ester transfer protein (CETP) polymorphism potentially related to recent findings demonstrating coronary risk with increasing high-density lipoprotein cholesterol (HDL-C) level. METHODS AND RESULTS A novel graphical exploratory data analysis tool allowed the examination of coronary risk(More)
This is the final report on reproducibility@xsede, a one-day workshop held in conjunction with XSEDE14, the annual conference of the Extreme Science and Engineering Discovery Environment (XSEDE). The workshop's discussion-oriented agenda focused on reproducibility in large-scale computational research. Two important themes capture the spirit of the workshop(More)
We describe a system called Olive that freezes and precisely reproduces the environment necessary to execute software long after its creation. It uses virtual machine (VM) technology to encapsulate legacy software, complete with all its software dependencies. This legacy world can be completely closed-source: there is no requirement for availability of(More)
The objective of this work was to investigate whether fibrinolysis plays a role in establishing recurrent coronary event risk in a previously identified group of postinfarction patients. This group of patients was defined as having concurrently high levels of high-density lipoprotein cholesterol (HDL-C) and C-reactive protein (CRP) and was previously(More)
Data is presented that was utilized as the basis for Bayesian network modeling of influence pathways focusing on the central role of a polymorphism of plasminogen activator inhibitor-2 (PAI-2) on recurrent cardiovascular disease risk in patients with high levels of HDL cholesterol and C-reactive protein (CRP) as a marker of inflammation, "Influences on(More)
Information Assurance (IA), cybersecurity, digital forensics: Uniquely integrating experience in academia, industry and government, I apply a multidisciplinary approach to research questions and curriculum development that address the unintended consequences of society's embrasure of pervasive, networked computing. I have investigated questions concerning:(More)
