UC College of Arts and Sciences assistant professor Elizabeth Hobson contributed to three articles in the journal Philosophical Transactions of the Royal Society B, including an analysis of the past 50 years of research in dominance hierarchies or pecking orders.
Hobson has studied how monk parakeets quarrel with competitors closest in status to cement their positions rather than wasting effort fighting the lowest-ranking members of the colony.
"In the parakeets I work with, we don't find a strong correlation between size and dominance. Instead, individuals may need to recognize their rivals and remember past fights and outcomes to come up with a mental model of rank," she said. "That's a very different cognitive task than choosing to fight an opponent simply because it is slightly smaller than you."
Hobson's students will begin a new study in her lab this year looking at dominance hierarchies and other behavior in northern bobwhite quail.

UC professor leads film students to the future

As a kid, at the age of 10, Marty Schiff’s dad gave him a Kodak Brownie movie camera, and that led to a lifetime of creating stories on film. He spent his summers with that camera, making eight-millimeter movies, with a camera that taught him how to thread a projector, change the film in a closet, and tell stories with the medium he loved. “I always wanted to go to Hollywood,” Schiff says. So later he did, with $200 in his pocket, and began a career that has spanned acting, directing, producing—pretty much everything with the exception of costumes (“I’m not really good with a sewing machine,” he says).

Public transit is where Zane Sawyer’s lifelong passion for travel meets his commitment to making an impact. The University of Cincinnati first-year geography major in the College of Arts & Sciences and member of the second cohort of Hoffman Honors Scholars (HHS) has hit the ground running, designing a research project intended to capture both how public transit works and how its users perceive it.
