Biology professor Jeffrey Corbin recently published two papers describing the impacts of invasive species on native species. “Not novel, just better: Competition between native and non-native plants that share species traits,” published in Plant Ecology, details the degree to which a group of invasive grasses in California reduces growth of native grassland species. “Scale, disturbance, and productivity control the native-exotic richness relationship,” was published in Oikos and co-authored by Brody Sandel of UC-Berkeley. The second paper used an experimental system to test the correlation between the number of native species and the number of exotic species. On sabbatical during the 2009-2010 academic year, Corbin is a visiting research scientist at the Eastern New York Chapter of The Nature Conservancy.
Stephanie Silvestre, visiting assistant professor of French and Francophone Studies with a scholarly specialty in Caribbean studies, recently was invited to appear in a new public affairs program, Pulse, on WPBT2, the PBS affiliate in South Florida (serving Miami-Dade, Broward, Palm Beach and Monroe counties). Pulse focuses on the Caribbean and the Caribbean-American experience in South Florida. Silvestre discussed the pros and cons of being a European territory in the Caribbean. Several Caribbean islands are still territories of their former colonial rulers, such as Aruba, which is Dutch, and Martinique and Guadeloupe, which are French. The program aired April 18 and April 22. To watch, click here. Go to: “Pulse: Former Colonies in the Caribbean.”
Helen Hanson, assistant professor of electrical and computer engineering, had a paper published in the Journal of the Acoustical Society of America. The title is “Effects of Obstruent Consonants on Fundamental Frequency at Vowel Onset in English.” The paper provides evidence that a well-known phonetic effect in speech production, called "pitch skip," has a physiological basis, although speakers may learn to exaggerate it to make more salient the contrast between certain voiced and unvoiced consonants. In addition, it shows that this effect interacts with intonation. This research supports a theory of speech production and perception that posits that the linguistic representation of words in our brains is made up of discrete segments, which in turn are bundles of binary features.
In April, Hanson presented a poster co-authored with Angela McLelland ’11 of the Mechanical Engineering Department at the Meeting of the Acoustical Society of America, held in Baltimore. “Prosodic Analysis of Subglottal Pressure Contours” described their research on the control of lung pressure during speech production. The work included research done by McLelland at Union last summer. In addition, Hanson and Palma Catravas, assistant professor of electrical and computer engineering, participated in an outreach program at the conference. In "Listen Up and Get Involved," area Girl Scouts took part in more than 22 hands-on demonstrations. The session included a live Web broadcast from two female researchers doing research in underwater acoustics on a ship in the Philippine Sea.

Kevin Donovan '09 was named a finalist for the Eta Kappa Nu (HKN) 2009 Outstanding ECE Student Award. Eta Kappa Nu honors students with an interest and marked ability in electrical engineering who show exemplary scholarship, leadership and character. In addition, for the second straight year, the Phi Chapter of Etta Kappa Nu received an outstanding chapter award for 2008-2009. Chapters are judged on their activities of service to others.
