- ItemDeterminants of Student Demand at Florida Southern College(Journal of Case Research in Business and Economics, 2012-07) Brown, Carl C.; McClary, Andrea; Bellingar, JaredDetermining the factors impacting student demand for higher education at Florida Southern College enables calculation of the effect that tuition levels and other variables have on enrollment and revenue. A times series study utilizing data on published tuition, net tuition and fees, and other potential explanatory factors is conducted to determine their impact on both freshman and total enrollment levels at Florida Southern. Separate analyses of students hailing from Florida and from out-of-state are conducted to determine if there are significant differences in the factors impacting the decisions by these groups to enroll at Florida Southern. In addition, estimates of price elasticities of demand are calculated based on the available data. This study finds that price-adjusted net tuition (including fees) is a statistically significant determinant of freshman enrollment, as is real per capita income, the annual number of high school graduates, and the US unemployment rate. The net tuition elasticity of demand among Florida freshman students is -1.8, while net tuition is statistically insignificant as a determinant of enrollment by non-Florida freshman students. The study also finds that the price elasticity of demand for the aggregate freshman student population has increased over time as net tuition has risen in real terms. When tuition +fees and financial aid are entered as separate variables (as opposed to being combined as net tuition) into the regressions, the explanatory value of the regression equations increase.
- ItemPoly(methyl methacrylate) composites of copper-4,4′-trimethylenedipyridine(New Journal of Chemistry, 2012-07) Liu, Shisi; Ananthoji, Ramakanth; Han, Sungyub; Knudsen, Bernard; Li, Xiao; Wojtas, Lukasz; Massing, Justin; Gauthier, Carmen Valdez; Harmon, Julie P.A series of poly(methyl methacrylate) (PMMA) composites were prepared with a novel one dimensional coordination polymer copper-4,4′-trimethylenedipyridine (CU-TMDP). The CU-TMDP was sonicated in a methyl methacrylate monomer and polymerized in situ. Thermal, mechanical and optical properties of CU-TMDP–PMMA composites were probed via optical microscopy, Raman spectroscopy, differential scanning calorimetry (DSC), microhardness, and dynamic mechanical analysis (DMA). The CU-TMDP was characterized by X-ray crystallography. The functionality of the CU-TMDP interacted with the polymer matrix such that mechanical properties are tuned by varying CU-TMDP loadings. The data point to the fact that interactions are primarily due to London dispersion forces or dipole–dipole interactions. This initial study forms the basis for future applications requiring tailored mechanical properties.
