BLOOMINGTON, Ind. -- Scientists from the Indiana University School of Medicine and IU Bloomington are presenting on timely issues at the annual meeting of the American Association for the Advancement of Science in San Diego, Feb 18 - 22. IU Bloomington biologist Ellen Ketterson will also be honored as one of the association's newest fellows.

Deaf children benefit from getting cochlear implant earlier in life

Learning words may be dependent on early auditory input, according to a growing body of evidence, including a recent study by Indiana University School of Medicine Department of Otolaryngology researchers. Derek Houston and colleagues tested word-learning skills in 20 deaf children and 20 normal-hearing children of the similar ages. They found that deaf children's word-learning skills were strongly affected by their early auditory experience -- whether it was through normal means or through a cochlear implant. Children who received the implant by the age of 13 months performed similarly to their normal-hearing counterparts. Children who received an implant later performed, on average, more poorly than their normal-hearing peers. Additional findings showed that children who had some level of normal hearing early in life before cochlear implantation exhibited word-learning skills similar to the early implanted children.

"Language Learning in Deaf Children: Integrating Research on Speech, Gesture, and Sign," Sunday, Feb. 21, from 3:30 p.m. to 5:00 p.m., Room 2

GIS data show relationship between violence, liquor retailers

As cities grapple with liquor-related violence, new data suggests zoning commissions may want to take a second look at where they put liquor retailers. IU Bloomington criminologist William Pridemore and Geographer Tony Grubesic are in the midst of analyzing new Geographic Information Systems (GIS) data that seem to suggest violent crime is more likely to occur in the vicinity of stores that sell liquor expressly for off-premise consumption. Violence, they are learning, is less likely to occur near other types of establishments that offer alcohol, such as bars, pubs and restaurants. Pridemore and Grubesic have conducted their studies in Cincinnati (Ohio) neighborhoods using blocks as a unit of analysis. Pridemore led the research and is the session organizer. Grubesic will speak about the scientists' collaborative research, which is using GIS and other spatial analysis techniques to learn more about human behavior patterns.

"Using GIS and Spatial Analysis To Better Understand Patterns and Causes of Violence," Monday, Feb. 22, from 9:45 a.m. to 11:15 a.m., Room 5A

Grubesic and Pridemore will take part in a press briefing regarding "Using GIS and Spatial Analysis to Better Understand Patterns and Causes of Violence," at 2:00 p.m. PST on Sunday, Feb. 21, at the San Diego Convention Center. Please visit the Press Room beforehand for the event's location (TBD).
