Polarisation in lower-income countries largely flows from economic and material issues, while social topics and identity-related debates are the most polarising subjects in richer nations, new research reveals.
This study focuses on how primary care patients balance the trade-off between continuity of care and access to timely appointments. It examines whether patients prefer to wait longer to see their own primary care physician (PCP) or prefer to see another clinician for faster care.
This study aimed to identify specific strategies used by high-performing clinics to promote consistent follow-up visits for adults with chronic conditions.
A new Penn Nursing study reveals that expectant and new fathers, particularly Black American fathers, express a significant need for more resources and support to better assist mothers during pregnancy and childbirth. The research, published in BMC Pregnancy and Childbirth, highlights a gap in tailored information and resources for fathers within healthcare and social service systems.
Angela Duckworth of the School of Arts & Sciences and Wharton School and co-director of the Behavior Change for Good Initiative at the University of Pennsylvania led a collaborative megastudy to investigate whether email interventions informed by behavioral science could help teachers help students learn math. “Our results showed that simple, low-cost nudges can help teachers support student progress in math,” Duckworth says.
Mathematicians studied the flow of human crowds and developed a way to predict when pedestrian paths will transition from orderly to entangled. Their findings may help inform the design of public spaces that promote safe and efficient thoroughfares.
New Haven, Conn. — Most job candidates know to dress nicely for Zoom interviews and to arrange a professional-looking background for the camera. But a new Yale study suggests they also ought to test the quality of their microphones.
A tinny voice caused by a cheap mic, researchers say, could sink their chances.
Through a series of experiments, the study demonstrates that tinny speech — a thin, metallic sound — during video conferences can have surprisingly deep social consequences, leading listeners to lower their judgments of a speaker’s intelligence, credibility, and romantic desirability. It also can hurt an individual’s chances of landing a job. These effects could be a potential source of unintentional bias and discrimination, given the likelihood that microphone quality is correlated with socioeconomic status, the researchers said.
