Faculty, Staff and Student Publications

Isovalent doping offers a method to enhance the thermoelectric properties of semiconductors, yet its influence on the phonon structure and propagation is often overlooked. Here, we take CdX (X=Te, Se) compounds as an example to study the role of isovalent doping in thermoelectrics by first-principles calculations in combination with the Boltzmann transport theory. The electronic and phononic properties of Cd8Se8, Cd8Se7Te, Cd8Te8, and Cd8Te7Se are compared. The results suggest that isovalent doping with CdX significantly improves the thermoelectric performance. Due to the similar properties of Se and Te atoms, the electronic properties remain unaffected. Moreover, doping enhances anharmonic phonon scattering, …

Concealment And Darkness In Horace Walpole’S The Castle Of Otranto, Alexandra G. Speck

Global Tides

This paper examines the relationship between darkness and fear in Horace Walpole’s The Castle of Otranto, widely recognized as the first Gothic novel. Walpole wrote Otranto soon after the rise of Enlightenment thought, which stressed sensory observation as the foundation for human reason. Walpole engages with Enlightenment ideas through Otranto’s dark setting, which invokes fear and irrationality in the heroine, Isabella.

Tracking Walpole’s manipulation of light and darkness through the narrative, this paper illustrates how darkness inspires more fear in Isabella than either the novel’s infamous supernatural dangers or its human villain, Prince Manfred, who pursues her through …

Independent Reading In The High School Classroom: An Examination Of Students' Reading Behaviors And Perceptions, Emma Halfman

John Wesley Powell Student Research Conference

Independent reading is a time wherein students are allowed to read self-selected materials on their own (Yoon, 2002). Federal research like that of the National Reading Panel Report (NRP), however, has suggested that such programs in schools do not have conclusive benefits for students. Given this context, some administrators, teachers, and parents often do not advocate for independent reading in the classroom. They prefer instead that class time be spent wisely. They prefer that the class time be focused on the instruction of skills/content that matter to students and that align with state and national standards and assessments. With such …

Changing Prejudice Against Minority Groups: The Role Of Self- And Group-Affirmation, Constantina Badea, Yara Alnajjar

Online Readings in Psychology and Culture

According to self-affirmation theory, prejudice towards minority groups represents defensive reactions that individuals may exhibit to cope with threats to their ingroup. Affirming participants’ important values, reminding them of important personal or collective successes, attenuates defensive reactions such as prejudice and discrimination. A distinction is first made between self-affirmation, accomplished by recalling values that are meaningful to the individual, and group-affirmation, achieved through the recall of values important to an ingroup (e.g., family, nation). Inconsistent results were obtained in studies using self- and group-affirmation manipulations for reducing prejudice. The aim of this article is to examine factors that …
