Speeding is the riskiest kind of aggressive driving, according to a unique analysis of data from on-board devices in vehicles.
A new QUT-led study has developed a statistical toolbox to help avoid seagrass loss which provides shelter, food and oxygen to fish and at-risk species like dugongs and green turtles.
If you end up needing to go to the hospital, often times you're hoping to get a bed without having to wait hours, but a new study shows you may want to wait a little longer, so that you are placed in the best ward for your needs. New research in the upcoming INFORMS journal Management Science shows that among patients admitted to the hospital, 19.6% are placed in beds in a ward outside the area of care they require.
Capturing the motion of single molecules is achieved by a method known as fluorescence correlation spectroscopy (FCS). The catch? It takes many detections of light particles -- photons -- emitted by single molecules to get a clear picture of molecular motion.
Researchers from the University of Pittsburgh, UCLA and the University of Texas published new research in the INFORMS journal Marketing Science, that reveals the power of word-of-mouth in social learning, even when compared to the power of following the example of someone we trust or admire. The same research found, however, that both word-of-mouth and following someone else's lead are two of the most powerful dynamics in influencing others through social learning.
Several countries have combated low organ donor counts by implementing a priority rule that pushes registered donors to the front of the line if they ever need a transplant. However, according to a study from the McCombs School of Business at The University of Texas at Austin published today in Management Science, this model has drawbacks.
Scientists have created the world's first computer model to predict the movements of baby coral trout across the Great Barrier Reef. The models are validated by in-depth fieldwork and genetic tracking, and will help managers decide which areas need the most protection to ensure future adult populations of coral trout.
Gaining a full understanding of systems of exoplanets and distant stars is difficult, because the initial positions and velocities of the exoplanets are unknown. Determining whether the system dynamics are quasi-periodic or chaotic is cumbersome, expensive and computationally demanding. In this week's Chaos, Tamás Kovács delivers an alternative method for stability analysis of exoplanetary bodies using only the observed time series data to deduce dynamical measurements and quantify the unpredictability of exoplanet systems.
In a future when self-driving and other internet-connected cars share the roads with the rest of us, hackers could not only wreck the occasional vehicle but possibly compound attacks to gridlock whole cities by stalling out a limited percentage of cars. Physicists calculated how many hacked, stalled connected cars would cause how much mayhem.
New international research by Monash University has found that one way to overcome social dilemmas is through visible prosocial punishment -- the existence of collective institutions that punish individuals who don't cooperate.
