Chemistry Professor Charles Sharpless is the co-author of two recently published articles. The first, entitled “Photooxidation-induced changes in optical, electrochemical, and photochemical properties of humic substances,” was co-authored with colleagues from U.C. Berkeley and the Swiss Federal Institute of Technology (ETH Zurich) and appears in the current issue of the American Chemical Society journal, Environmental Science & Technology. A research article, it focuses on how prolonged exposure to solar radiation alters the photochemical and electrochemical properties of natural dissolved organic matter, ubiquitous brown “stuff” in surface waters that participates in many aspects of environmental aquatic chemistry. The second article, entitled “The importance of charge-transfer interactions in determining chromophoric dissolved organic matter (CDOM) optical and photochemical properties,” was co-authored with Professor Neil Blough (Chemistry, U. MD College Park). This was an invited review for the Royal Society of Chemistry’s journal, Environmental Sciences: Processes and Impacts, formerly The Journal of Environmental Modeling. The review, containing 247 references, deals with the optical and photochemical properties of natural dissolved organic matter, how those properties are related, and the relevance of these relationships for current research in environmental photochemistry. The article is currently in advance electronic format and will be published later this year in a specially-themed journal issue devoted to aquatic photochemical processes.
Kashef Majid, Assistant Professor of Marketing in the College of Business, and UMW business major Madeleine Bate, presented “Breadth vs. Depth – Linking Network Shape to Revenues, a Study of the Dispersion of Film Trailers via Twitter,” at the American Marketing Association Winter Educators Conference in Orlando from Feb. 21 to 23, 2014.

On Feb. 21 Martha Burtis and Jim Groom were invited to present about the open, online Digital Storytelling course ds106 at the OpenVCU Symposium. The presentation, “Open is as Open Does,” lays bare the various levels an open course like ds106 operates through. This talk breaks down teaching openly online into three parts: open platforms, open pedagogy, and open community. You can read about the presentation in more detail here or view the slide deck below.
Associate Professor and Chair of Mathematics, Randall Helmstutler, published the article “Conjugate pairs of categories and Quillen equivalent stable model categories of functors.” It appears in a recent issue of the peer-reviewed Journal of Pure and Applied Algebra.
Stephen Farnsworth, professor of political science and director of the University’s Center for Leadership and Media Studies, recently gave a lecture entitled, “Journalism and U.S. Foreign Policy: Global Media and Politics in Transition,” to visiting journalists from Yemen who were part of a recent Institute for International Education Visitor Leadership Program. The Washington-based program was sponsored by the U.S. Department of State.
Paul Fallon, Associate Professor of Linguistics, presented the paper “The Lexicostatistics of Central Cushitic (Agaw)” at the 42nd annual meeting of the North American Conference on Afroasiatic Linguistics (NACAL), held this year at the University of Leiden, The Netherlands, Feb. 14-16, 2014.
Associate Professor in the College of Business, Dr. Xiaofeng Zhao’s article, “Nonlinear Programming,” has been accepted by the Encyclopedia of Business Analytics and Optimization (EBAO). The article will be published by IGI Global in 2014. Another article by Dr. Zhao, “Linear Programming,” will also be published in EBAO.
Assistant Professor of Computer Science, Dave Toth, and his students Zach Goodywyn and Jerome Mueller published a paper on the research they conducted during this year’s UMW Summer Science Program. The paper compares the performance of the Intel Xeon Phi coprocessor and an NVIDIA K20c GPU. Prof. Toth also presented the work at the PDCN conference in Austria last week.
On Feb. 5, 2014, Melva Kishpaugh, UMW Assistant Director of Procurement Services, joined other members of the Virginia Association of Governmental Purchasing (VAGP), during VAGP’s “Day on the Hill” in Richmond, Va. The team met with various legislators and members of the administration to discuss procurement issues within the Commonwealth.
