Persuasive Strategies and Hats Off for Cancer Donations
This quantitative research project set out to answer the question, “What type of advertising strategy, logos, ethos, or pathos, will be most effective in increasing donations to Hats Off for Cancer, a nonprofit organization?” By administering a survey including manufactured advertisements to potential donors through the Hats Off for Cancer e-newsletter, the Hats Off for Cancer Facebook page, and my own Facebook network, I received 44 responses. These responses indicated the participants’ involvement with the organization as well as their preferred advertising strategies and their reasoning for this. 79 percent of respondents felt that the advertisement using pathos was most effective while 19 percent said logos and 2 percent said ethos. These responses were valuable, and based on the respondents’ reasoning behind their preferences, I constructed three implications for Hats Off for Cancer’s future advertising endeavors

[2,3:5,6]Dibenzo[2.2.2]octa-2,5,7-triene (C2/c) and [2,3:5,6]dibenzo[2.2.2]octa-2,5-diene
Two barrelene homologs are reported. Strain in the bicyclic framework of [2,3:5,6]dibenzo[2.2.2]octa-2,5,7- triene, (I) (C16H12), which is manifest in the deviations from ideality of the bond angles in the central bicyclic ringoSyStem and compression of the double bond [1.312 (3)A], is reduced in the more saturated derivative, [2,3:5,6]dibenzo[2.2.2]octa-2,5-diene, (II) (CI6H14), with the corresponding single bond being 1.5380 (19)A. The formation of isomorphs of (I) in both chiral (C2) and achiral (C2/c) space groups has implications for asymmetric syntheses involving solid (I) which rely on a non-centrosymmetric space group
9-Phenyl-3,4,4a,9a-Tetrahydrotriptycene and 9-Phenyl-1,2,3,4,4a,9a-Hexahydrotriptycene
The structure of 9-phenyl-3,4,4a,9a-tetrahydrotriptycene, C26H22, (I), exhibits regiochemistry consistent with a stepwise mechanism for its formation from photocycloaddition of 1,3- cyclohexadiene and 9-phenylanthracene. Bond distances involving the bridgehead C atoms are similar in (I) and the hydrogenated derivative, 9-phenyl-1,2,3,4,4a,9a-hexahydrotriptycene, C26H24, (II), with bonds to the quaternary-C atoms exhibiting significant elongation [1.581 (2) A Ê in (I) and 1.585 (2) A Ê in (II)]. The molecular geometry precludes significant overlap between the phenyl groups and the interannular bonds in both compounds, indicating that the origin of the bond lengthening is steric in nature
Polymeric routes to silicon carbide and silicon oxycarbide CMC
An overview of two approaches to the formation of ceramic composite matrices from polymeric precursors is presented. Copolymerization of alkyl- and alkenylsilanes (RSiH3) represents a new precursor system for the production of Beta-SiC on pyrolysis, with copolymer composition controlling polymer structure, char yield, and ceramic stoichiometry and morphology. Polysilsesquioxanes which are synthesized readily and can be handled in air serve as precursors to Si-C-O ceramics. Copolymers of phenyl and methyl silsesquioxanes display rheological properties favorable for composite fabrication; these can be tailored by control of pH, water/methoxy ratio and copolymer composition. Composites obtained from these utilize a carbon coated, eight harness satin weave Nicalon cloth reinforcement. The material exhibits nonlinear stress-strain behavior in tension
