Agricultural economists have devoted considerable attention to
the financial stress situation of agricultural producers. Many
studies have been conducted in various regions of the U.S. in an
attempt to better understand the causes of the problem. The costs
associated with farm financial stress imply corresponding benefits to
be realized by...
In this study, pheromone and skin lipid samples collected from red-sided garter snakes (Thamnophis sirtalis parietalis) were exposed directly to either full-spectrum light or full-spectrum plus UVB light. In addition, female and male snakes were exposed to daily doses of either full-spectrum or full-spectrum and UVB light, after which the...
The immune system has been identified as a very sensitive target for the toxic effects of 2,3,7,S-tetrachlorodibenzo-p-dioxin (TCDD). Exposure to TCDD has been shown to disrupt the generation of both cell-mediated and humoral T cell-dependent immunity in laboratory animals; however, the mechanism remains unknown. In this dissertation, the hypothesis is...

Although perceived-risk curriculum, that is, where the learner experiences effects of eustress (positive stress), has been used in Arts or outdoor activities, it has not been used in school classrooms. Milkman’s 1996 studies of after-school Project Self Discovery demonstrated that at-risk students lessened their adverse risky behaviors, such as substance...
Two perovskite materials (Bi0.5(A)0.5)(Sc0.5Nb0.5)O3, where A = K+ and Na+ were synthesized phase pure for the first time. Their structures were determined by indexing synchrotron X-ray diffraction data and subsequent combined Rietveld refinement on neutron and synchrotron X-ray diffraction data revealing significant disorder on the A-sites of these materials. A...
This investigation was designed to determine the general achievement,
ability to solve applied problems, and attitude toward the role of
mathematics in science of college calculus students grouped in an
experimental class according to academic major during their first
three terms. The subgroups were biology-business, mathematics,
and science-engineering majors. The...
