UA Professor Named First Billingsley Chair In Educational Research and Policy Studies
-- Posted by tfisher on Tuesday, December 7 2004
Dr. Sean Mulvenon, University of Arkansas professor specializing in educational statistics and director of the National Office for Research, Measurement and Evaluation Systems, has been named the first holder of the George M. and Boyce W. Billingsley Endowed Chair in Educational Research and Policy Studies.
His appointment will be celebrated at a ceremony at 10:30 a.m. Wednesday, Dec. 8, in the foyer of the Graduate Education Building Auditorium.
The chair was endowed by the Billingsleys to focus primarily on the development of leading-edge computer-based systems in education policy, research and statistics in coordination with multidisciplinary programs across campus.

Yellowstone Lake Shore Changing; UA Scientists Investigating Causes
-- Posted by tfisher on Thursday, December 2 2004
A University of Arkansas researcher has found that, in the past 50 years, the shoreline on a segment of Yellowstone Lake has been changing in complex ways that are not completely understood.
Barbara Pickup, graduate student in the environmental dynamics program at the University of Arkansas, presented her findings at a recent meeting of the Geological Society of America.
To look at erosion processes over time, Pickup and geosciences professor Steve Boss used aerial photographs taken of the shoreline in the West Thumb basin at Yellowstone Lake in Yellowstone National Park between 1954 and 2002. Pickup used a photo taken in 1994, which had been geographically corrected using Geographic Information Systems to pinpoint the exact location of each pixel, to calibrate the other photographs. She then measured the shoreline in each photograph at 20-meter intervals to determine the net change from photo to photo. When she and Boss examined the data, they found that overall the shoreline has receded. However, they also found something unexpected.
"We're seeing substantial change along the shoreline and it's not uniform around the basin," Pickup said. Normally, a lake shoreline would advance or recede much like the water in a bathtub -- evenly around the whole tub, Boss said. However, the data from Pickup's study show one side of the basin receding while other parts remain stable or advance -- and later the processes reverse.

Poultry Science Graduate Students Donate 300 Turkeys to Ozark Food Bank
-- Posted by tfisher on Thursday, December 2 2004
Members of the Poultry Science Graduate Association (PSGA) at the University of Arkansas recently donated 300 turkeys to the Ozark Food Bank.
"We had turkeys that were not currently being used for a research project, so Amanda Wolfenden, our president, got the graduate students together and came up with the idea that if the poultry science department could spare them, PSGA could provide the labor necessary to raise and process the birds so they could eventually be donated to the Ozark Food Bank," said Lisa Bielke, past president of PSGA.
"Each day graduate students would head to the farm to care for the birds with the hope that this holiday, we could make a difference in the lives of hundreds of Northwest Arkansas families," said Bielke.
The birds were processed and delivered to the Ozark Food Bank on November 17th for distribution.
Not to be outdone by the graduate students, undergraduate members of the Poultry Science Club (PSC) have set up boxes on each floor of the Center of Excellence for Poultry Science building and are gathering food from faculty, staff and students, which will also be donated for Thanksgiving dinners.
