Undergraduate Writing in the Sciences: A Case Study
Susan Browning & Jon Bruce Obray
This research project is an attempt to understand the role of writing in undergraduate science education, including the development of writing's current role in scientific education, the present nature of writing in the scientific disciplines, and its value. With this understanding, we feel it is possible to successfully improve the communication skills of undergraduates students in the scientific disciplines, which in turn will benefit both the scientific community and society itself. A case study of...
Banking in China: Fiscal Policy Under Pressure
Thor Roundy
The radical changes occurring in China can be both exciting and frightening. Attempting to keep in reign a skyrocketing economy, Chinese Leaders such as Liu Hongru and Zhang Wei have become modern day entrepreneurs in creating a new national economy. Like typical entrepreneurs, Chinese leadership is making decisions by the seat of their pants, attempting to control growth under volatile new conditions of reform.
Iron-Dithiothreitol Dependent Production of 8-Hydroxy-2'-Deoxyguanosine in DNA
David Allan Cook
Oxidative damage to DNA in a metal-thiol system was studied. Calf thymus DNA was incubated in an iron(IIl)-dithiothreitol system prepared in various buffers. Damage was measured by monitoring the production of 8-hydroxy-2'-deoxyguanosine. DNA oxidation was proportional to the concentration of dithiothreitol (DTT) in HEPES and tris(hydroxymethyl)aminomethane (Tris) buffers while it was only roughly related to DTT concentration in sodium chloride. Incubation in potassium phosphate buffer produced no damage. The results indicate that hydroxyl radicals may...
The Proposed Use of an Anatomically Marked Presurgically Fitted Prostheses With Infants Who Have Unrepaired Cleft Palates
Amy Moser
Approximately one out of every 750 children are born with some type of an oral cleft (McWilliams, Morris, & Shelton, 1984) Children with clefts of the palate in general have a higher incidence of articulation disorders than do children without clefts. Typical speech problems which tend to occur are hypernasality and multiple articulation errors, often consisting of atypical tongue placement in the mouth or nontypical articulation at sites in the larynx or pharynx. These speech...
MEPS Data Assimilation System
Robert W. Schunk & Larry Gardner
For the current funding opportunity we propose to develop a master system that will enhance the user interface to the MEPS model and enable the scientific community to efficiently use the model. Furthermore, we will build and automate validation tools and improve the efficiency and robustness of the MEPS ensemble averaging scheme. Finally, we will explore the nest step toward a major advancement in MEPS b significantly improving the spatial resolution of one of the...

Mechanism of Photochemical N2 Reduction
Lance SeefeldtHerbicide Control of Broom Snakeweed (Gutierrezia sarothrae)
Clinton A. Stonecipher, Corey Ransom, Eric Thacker & Kevin D. Welch
Broom snakeweed (Gutierrezia sarothrae [Pursh] Britton & Rusby) is a native invasive species that is widely distributed across western North America. It is very competitive with other vegetation and can reduce or displace desirable grasses and forbs. Removal of snakeweed from rangelands can result in increased forage production of desirable plant species. The evaluation of new herbicides to determine their efficacy in controlling broom snakeweed assists in providing land managers with alternatives to control broom...
