SUTD researchers used mobile phone GPS traces, street view imagery, and open-source spatial data to show that pedestrian route choices in a rapidly developing city are shaped far more by street conditions and context than by distance alone.
Frequent exposure to real-world firearm violence through media is associated with worse mental health outcomes, according to Rutgers researchers.
Their study, published in BMC Public Health, found that frequent exposure to firearm-related content is linked to higher levels of depression and more days of poor mental health among adults in the United States.
Large language models may be able to make moderation of social media and online communities more effective, but they are expensive to run at scale, especially when asked to provide explanations for each piece of content they flag. Yuan Zhao will present research on creating an interpretable and low-cost method for evaluating LLMs’ hate speech classification as part of 190th ASA Meeting. His framework relies on the Rational Inattention model, an economic idea developed to explain human behavior.
A new UC Irvine study uses monetized life-cycle analysis to compare hydrogen, direct electrification and fossil fuel pathways across heavy-duty transport and industrial sectors. The researchers concluded that renewable hydrogen applied in certain sectors offers greater social value, which includes reduced climate change impacts, cleaner air, improved public health and lower demand for natural resources. The researchers pinpointed steel, transoceanic shipping and long-haul trucking as the highest-value targets for clean hydrogen deployment.
