In most emergency departments, beds are a hot commodity. But some patients don’t actually need a bed for their treatment – and accurately identifying those people is a low-lift but effective way to increase efficiency without sacrificing care quality, finds a study recently published in the journal Management Science.

The researchers developed a simple decision tree, informed by mathematical and machine learning models, to help staff decide whether a patient truly needs a bed or can be routed to a “vertical processing pathway” – that is, an area where they can be treated sitting up. Many hospitals already have such an area but don’t necessarily have a systematic way to decide which patients are treated there.

American teenagers start their school day too early.

Medical experts have been clear for years: sleep cycle changes during puberty make it hard for teenagers to learn in the early morning. Later school start times have been linked to better sleep, improved mental health, stronger academic performance and even safer driving.

Most school district leaders know about this problem and care about fixing it. But changing the schedule can feel operationally impossible.

New Response Plans Allow Cross-trained Firefighters and EMS Workers to Respond to Either Call, Saving Millions of Dollars

New Response Plans Allow Cross-trained Firefighters and EMS Workers to Respond to Either Call, Saving Millions of Dollars

News Release, February 9, 2023

BALTIMORE, MD, February 9, 2023 – According to a new study, changing the response plans for fire and emergency service personnel is proving to have top-dollar savings. New research in the INFORMS journal Manufacturing & Service Operations Management finds that pooling resources to have cross-trained fire-medics respond to both emergency medical calls and fire incidents, rather than having firefighters respond to fires and emergency medical personnel respond to medical incidents, can save more than $3 million a year.

How dangerous is AI? Regulate it before it’s too late

How dangerous is AI? Regulate it before it’s too late

The Hill, February 8, 2023

As an Artificial Intelligence researcher, I’ve always felt the worst feature of AI is its role in the spread of lies. The AI-amplification of lies in Myanmar reportedly contributed to the Rohingya massacre, the spread of COVID-19 and vaccine misinformation likely contributed to hundreds of thousands of preventable deaths and election misinformation has weakened our democracy and played a part in the Jan. 6, 2021 insurrection. This was all possible because humans turned algorithms into weapons, manipulating them to spread noxious information on platforms that claimed to be neutral. These algorithms are all proprietary to companies, and they are unregulated. And so far, none of the companies have admitted any liability. Apparently, no one feels guilty.

Red means stop, green means go, but NCSU researchers propose fourth signal color for autonomous vehicles

Red means stop, green means go, but NCSU researchers propose fourth signal color for autonomous vehicles

WRAL, February 7, 2023

RALEIGH – At a traffic light, red means stop and green means go. But transportation engineers at North Carolina State University are now proposing a “white light,” which would enable autonomous vehicles to help control traffic flow – and let human drivers know what’s going on. In computational simulations, the new approach significantly improves travel time through intersections and reduces fuel consumption.

Severe Weather Straining Electrical Grids: New Research Mitigates Demand Surges, Increasing Grid Reliability and Reducing Costs

Severe Weather Straining Electrical Grids: New Research Mitigates Demand Surges, Increasing Grid Reliability and Reducing Costs

News Release, February 8, 2023

BALTIMORE, MD, February 8, 2023 – Concerns are mounting among policymakers and utility companies amid the impact of severe weather on the nation’s electrical grids. In recent months, electrical grids in Texas have been tested to the point of near failure. So it seems like perfect timing that new research in the INFORMS journal Management Science identifies a new method that provides the best way to utilize “direct load control contracts” to mitigate electricity demand surges, increase grid reliability and reduce electricity cost. All of this right down to the individual household.
