This is the first study to use field-level data to assess GR technology with a mammalian toxicity environmental indicator. It has been found that GR crops have a positive environmental effect, and that alternatives to GR technology increase toxicity.

This study examines the relationship between formal library instruction and undergraduate student performance and persistence in higher education. Researchers analyzed two years of academic and demographic data collected from first-time freshmen at Middle Tennessee State University in an attempt to quantify the effect of librarian-led one-shot classroom instruction on students' grade point averages and their likelihood of returning to school for the sophomore year. 49[ARTICLE]

The University of Tennessee developed a flowering dogwood tree (Cornus florida) that is resistant to powdery mildew (Microspaera pulchra). A simulated cooperative game was created to estimate a university fee and predict the behavior of nursery growers and nursery product retailers. The simulation suggests a university fee of $3.51, leading to an average retail price premium for the resistant tree of $10.41. At this price level the simulation predicts that 62 percent of all retail dogwood trees sold would be powdery mildew resistant. Based on 1998 sales of 1.475 million dogwood trees nationwide, 914,500 were predicted to be the powdery mildew resistant varieties, resulting in $3.2 million in revenue for the university. Given this level of sales and markup pricing, the cost of the trees will rise in subsequent stages of the distribution channel, and revenues will increase as well. The simulation suggests nursery revenue will increase by nearly $4 million and costs by $3.2 million, resulting in a net nursery gain of $0.8 million. Similar computations for the retail level are $9.5 million in revenue and a net increase of $5.5 million.
