Description: This presentation is part of the faculty lecture series UNT Speaks Out on the 2012 Presidential Primaries. In this presentation, the author gives the audience an overview of the structure of the primaries, and provides a recap of past primaries. The author also speaks about the money, momentum, and media attention in the primaries.

Description: This article discusses Abraham model correlations for the transfer of neutral molecules and ions to sulfolane. Data have been compiled from the published literature on the partition coefficients of solutes and vapors into anhydrous sulfolane. The logarithms of the water-to-sulfolane partition coefficients, log P, and gas-to-sulfolane partition coefficients, log K, were correlated with the Abraham solvation parameter model. The derived correlations described the observed log P and log K values for solutes dissolved in sulfolane to within average standard deviations of 0.14 log units or less. The log P correlation was extended to include the partition of ions by inclusion of a cation-solvent and an anion-solvent term.

Description: This article discusses the activation of water on the TiO2 (110) surface. Abstract: Using first-principles calculations the authors have studied the reactions of water over Ti adatoms on the (110) surface of rutile TiO2. The authors' results provide fundamental insights into the microscopic mechanisms that drive this reaction at the atomic level and assess the possibility of using this system to activate the water dissociation reaction. In particular, the authors show that a single water molecule dissociates exothermically with a small energy barrier of 0.17 eV. After dissociation, both H⁺ and OH⁻ ions bind strongly to the Ti adatom, which serves as an effective reactive center on the TiO2 surface. Finally, clustering of Ti adatoms does not improve the redox activity of the system and results in a slightly higher energy barrier for water dissociation.

Description: This poster discusses an analysis of how business students engage in learning in an introductory data analysis course. A variety of pedagogical activities are used in this introductory data analysis course for business students. In fall of 2012, students were able to score points on each of the following activities: experiential group projects, clicker questions, learning modules, online post chapter quizzes, in class exams, and extra credit questions. An analysis was performed to determine how these activities relate to each other and to improvement in student grades.

Description: In this article, the authors discuss the idea that non-philosophers should judge philosophers. As universities face growing demands for academic accountability, philosophers ought to take the lead in exploring what accountability means. Otherwise we may be stuck with Dickens's Mr. Gradgrind. ("Now, what I want is Facts. Teach these boys and girls nothing but Facts. Facts along are wanted in life.") But a philosophical account of accountability will also require redefining the boundaries of what counts as philosophy.
