State education secretary visits University Without Walls

Massachusetts Secretary of Education Paul Reville visited the University Without Walls Nov. 20 to see first-hand how innovations in technology and online learning are opening doors for adult students living and working in the Commonwealth.
 
Reville's visit was part of his statewide tour aimed at gathering information on best practices in educational technology in K-12 and higher education settings.

During the visit, Reville met with UWW director Ingrid Bracey, who described the program’s model.

Researchers use biomarkers from prehistoric human feces to track settlement and agriculture

For researchers who study Earth’s past environment, disentangling the effects of climate change from those related to human activities is a major challenge, but now campus geoscientists have used a biomarker from human feces in a completely new way to establish the first human presence, the arrival of grazing animals and human population dynamics in a landscape.
 
Doctoral student Robert D’Anjou and his advisor Raymond Bradley, director of the Climate System Research Center, with colleagues Nick Balascio and David Finkelstein, describe their findings in the current online edition of

Ganz developing new system to save lives at mass-casualty disasters

Aura Ganz, professor of Electrical and Computer Engineering, has been awarded a four-year, $1.6-million grant from the National Institutes of Health (NIH) to continue her research on a computerized disaster-management response system. Ganz says the system is designed to quickly organize chaotic, mass-casualty, disaster scenes, such as airliner, bus and train wrecks, and cut the evacuation time of survivors in half.
 
For the past several years, Ganz has been developing what she calls the DIORAMA I system, designed to coordinate the initial response in mass-casualty incidents and improve the

Campus sharing $6.24 million NSF grant to improve computer science education nationally

Building on its success in drawing more women and under-represented minority students to study computer science at Massachusetts public colleges and universities over the past five years, the campus’s Commonwealth Alliance for Information Technology Education (CAITE) has won a major grant from the National Science Foundation (NSF) and will now take a national leadership role in computer science education.
 
CAITE will share the new five-year, $6.24 million NSF grant with Georgia Computes!, a project at Georgia Tech, to create a national resource for other states that want to learn how to

Sitaraman's study quantifies how online video stream quality affects viewer behavior

It may seem like common sense that the quality of online video streaming affects how willing viewers are to watch videos at a website. But until Computer Science researcher Ramesh Sitaraman and collaborators at Akamai developed a way to rigorously study the question, no one had been able to scientifically test the assumption.
 
They conducted the first large-scale study of its kind to quantitatively demonstrate how video stream quality causes changes in viewer behavior. “Video stream quality is a very big topic of interest,” says Sitaraman.
