Comparing A Narrative And Didactic Approach To An Invasive Species Education Video, Tim Campbell, Bret Shaw, Amulya Rao, Jenna Klink, Feiran Chen

Journal of Extension

Video is a common tool for engaging audiences in Extension topics, yet evaluation of the different video production approaches is lacking. We compared learning and emotional outcomes after boaters in the Great Lakes watched either a narrative or didactic video focused on how to prevent the spread of an aquatic invasive species. There were differences in how each approach affected viewers, indicating that there can be utility in both approaches to video production. Extension staff that are creating videos should have these outcomes in mind to promote desired behaviors.

A Limited-Preemption Scheduling Model Inspired By Security Considerations, Benjamin Standaert, Fatima Raadia, Marion Sudvarg, Sanjoy Baruah, Thidapat Chantem, Nathan Fisher, Christopher Gill

Computer Science and Engineering Faculty Research

Safety-critical embedded systems such as autonomous vehicles typically have only very limited computational capabilities on board that must be carefully managed to provide required enhanced functionalities. As these systems become more complex and inter-connected, some parts may need to be secured to prevent unauthorized access, or isolated to ensure correctness.

We propose the multi-phase secure (MPS) task model as a natural extension of the widely used sporadic task model for modeling both the timing and the security (and isolation) requirements for such systems. Under MPS, task phases reflect execution using different security mechanisms which each have associated execution time costs …
