A photograph taken by the "single-pixel camera" built by Richard Baraniuk and Kevin Kelly of Rice University. (a) A photograph of a soccer ball, taken by a conventional digital camera at 64 × 64 resolution. (b) The same soccer ball, photographed by a single-pixel camera. The image is derived mathematically from 1600 separate, randomly selected measurements, using a method called compressed sensing.

He has subsequently applied optimization, statistics, and machine learning in a variety of industry settings, including online advertising, auto pricing, and airline revenue management. His current research interest is in online bipartite matching. Outside of mathematics Richard maintains a passion for soccer but fears that his dream of captaining Arsenal in the FA Cup Final may have passed him by.

When Renee Fister was three years old, she lost her younger brother, then 18 months old, to cancer. Growing up, she hoped to go to medical school so that she could fight the disease that claimed her brother. But along the way, she discovered that she didn't have the stomach for medicine—and that she liked mathematics a lot. She changed her plans, but reluctantly. " I thought I wouldn't be able to work on cancer any more, " she says. A generation ago, that might have been true. To mathematicians, biology seemed too nebulous, too hard to pin down with the precise laws and calculations that work so well in physics and engineering. Though mathematicians did have some success in genetics and population biology, a serious mathematical theory of cancer seemed like a figment of the imagination. Now, though...

Data were collected through self-reported ratings on a 7-point Likert-type scale. Exploratory factor analysis (EFA) was performed on an initial sample (N=354) and the result revealed that pre-service teachers' computer self-efficacy was explained by three factors: Basic Computer Skills (BCS), Media-Related Skills (MRS), and Web-Based Skills (WBS). Using a separate sample (N=354), a confirmatory factor analysis was performed and this supported the three-factor structure from the initial EFA. A comparison of alternative models revealed that the correlated three-factor and second-order (three-factor) models had the best fits; and were adequate representations of pre-service teachers' computer self-efficacy.
