UD faculty member teaches sociology and statistics with technology

Victor Perez, an assistant professor in the University of Delaware’s Department of Sociology and Criminal Justice, has found multiple ways to reach students using diverse technological approaches. Perez makes his classroom presentations highly interactive by combining a tablet with an engaging PowerPoint presentation.

Using the Wacom Bamboo tablet and its accompanying app, Perez creates illustrations of statistical formulas and distributions in class. “Bamboo Dock is something that I’ll use pretty frequently in the statistics course, and it looks literally like a journal. What’s great about this is that you can write any statistical formula, and it’s what students will see directly on the screen,” Perez said. (more…)

Wind Power’s Potential

UD-Stanford team calculates maximum global energy potential from wind

Wind turbines could power half the world’s future energy demands with minimal environmental impact, according to new research published by University of Delaware and Stanford University scientists in the Proceedings of the National Academy of Sciences.

The researchers arrived at the determination by calculating the maximum theoretical potential of wind power worldwide, taking into account the effects that numerous wind turbines would have on surface temperatures, water vapor, atmospheric circulations and other climatic considerations.

“Wind power is very safe from the climate point of view,” said Cristina Archer, associate professor of geography and physical ocean science and engineering at UD. (more…)

Research finds infants classify faces by gender, race

Long before babies can talk — even before they can sit up on their own — they are mentally forming categories for objects and animals in a way that, for example, sets apart squares from triangles and cats from dogs, psychologists say.

Now, research conducted by the University of Delaware’s Paul Quinn, professor of psychology, and others indicates that babies as young as 3 months are also classifying faces by race and gender, showing a visual preference for the category they see most often in their daily lives, and that by 9 months they have difficulty recognizing the faces of people from less-familiar races.

On The Front Lines

UD scientist sees Arctic ice loss firsthand

The extent of sea ice in the Arctic has reached a record low, according to data released Aug. 26 by the U.S. National Snow and Ice Data Center (NSIDC).

A University of Delaware marine scientist can confirm some of that ice loss firsthand. In a short video he produced, Andreas Muenchow, aboard the Canadian icebreaker Henry Larsen, shows the ice-free sea off Petermann Fjord that he and his colleagues were sailing in — an area that for ages had been covered by floating ice shelves.

Delaware Geological Survey discovers evidence of past earthquakes

Delaware Geological Survey (DGS) scientists have uncovered hard proof of faults in northern Delaware, indicating the occurrence of earthquakes millions of years ago.

The geologic evidence turned up in sediment samples removed during a well-drilling project this summer from depths ranging 137 to 251 feet down in Smyrna and the Woodland Beach Wildlife Area.

“People have postulated that there are faults in this area,” DGS Senior Scientist Scott Andres said. “Now we have evidence of it.” (more…)

Teaching using Technology

UD prof engages students with Facebook Groups and Google Sites

Phillip Penix-Tadsen, assistant professor of foreign languages and literatures at the University of Delaware, is reaching his students at new levels inside and outside the classroom. The spring 2012 semester was the first time Penix-Tadsen required the use of Facebook Groups by all his students to increase engagement and participation.

“That virtual space builds a kind of community for the class that leads into the in-class interactions. Students get to know one another in the Facebook Group, which leads to stronger class conversations and discussions,” Penix-Tadsen said. (more…)

University art conservation student prepares Blue Hen for display

When University of Delaware Prof. Jack Gelb, Jr., was given a taxidermy specimen of a Blue Hen by a retiring colleague in the Department of Animal and Food Sciences, he realized that this particular example of the Delaware state bird was somewhat the worse for wear.

And so Gelb, who is chairperson of the department as well as director of UD’s Avian Bioscience Center, turned to the Department of Art Conservation for expert help.

“This was a wonderful opportunity for me to learn about natural history materials,” said Elena Torok, now a third-year graduate student in the Winterthur-University of Delaware Program in Art Conservation. “We happily agreed to work” on the project. (more…)

Weevils and Weeds

UD researchers use weevils to check spread of prolific mile-a-minute weed

Mile-a-minute weed has declared war on Doug Tallamy’s yard. This non-native, invasive vine is growing up his trees, scrambling over shrubs and smothering tree seedlings. By blocking sunlight, it weakens a plant by reducing its ability to photosynthesize.

Mile-a-minute doesn’t care one whit that Tallamy, professor and chair of the University of Delaware’s Department of Entomology and Wildlife Ecology, is a highly respected proponent of native gardening who doesn’t believe in planting any non-natives, let alone a highly invasive non-native.

“The deer brought mile-a-minute from our neighbor’s yard three years after we moved in,” says Tallamy. “We had just a few plants the first year, a few hundred the second year, and 20 trillion the third year.” (more…)
