The Stereochemistry Of Selected Supramolecular Complexes Of Cucurbiturils And The Effect Of Homogeneous Equilibria And Electron Transfer Of The Guest, Arumugam Thangavel

Doctoral Dissertations

"From a practical perspective, host-guest complexes are vehicles for understanding and using supramolecular interactions for purposeful function in sensors, molecular machines and switches, while from a fundamental perspective they may lead to novel supramolecular protection schemes in basic organic reactions. This dissertation examines the interactions of cucurbiturils as barrel-shaped hosts, exhibiting a hydrophobic cavity, with substituted benzoylpyrydinium, phenypyrylium, and diazaanthraquinonediium cations as guests. In water, N-methyl-4-(p-substituted benzoyl)pyridinium cations exist in equilibrium with their hydrated forms (gem-diols), whose concentrations depend on the para substituent. In the presence of cucurbit7uril (CB[7]), the benzoyl group shows a preference for the CB[7] cavity, and …

Supplementing Accelerated Reading With Class-Wide Interdependent Group-Oriented Contingencies, Danielle N. Pappas, Christopher H. Skinner, Amy L. Skinner

Faculty Publications - Graduate School of Counseling

An across-groups (classrooms), multiple-baseline design was used to investigate the effects of an interdependent group-oriented contingency on the Accelerated Reader (AR) performance of fourth-grade students. A total of 32 students in three classes participated. Before the study began, an independent group-oriented reward program was being applied (i.e., a student received access to a tangible reward after passing each AR comprehension test). This program was supplemented with an interdependent group-oriented contingency, and results showed that the number of quizzes passed per week increased immediately after the intervention was applied; however, this increase was not maintained. When students were divided into ability …

American English Listeners’ Discrimination Of Australian, South African And Southeast England Varieties Of English: What Variation Matters?, Wendy Baker, Lyndsay Nay

Faculty Publications

Recent studies suggest that listeners are able to identify regional varieties of their native language (Clopper & Pisoni, 2007; Gooskens, 2005). These studies have also demonstrated that listeners use specific vowel, consonant, and intonational variation to make these identifications (Clopper & Pisoni, 2004; van Bezooijen & Gooskens, 1999). In most of these previous studies, however, listeners were asked to identify varieties with which they had at least some contact. What is not known is whether listeners can also distinguish between varieties with which they have little or no exposure and what linguistic features they use to do so. In particular, …

Faculty Publications

To evaluate the effective components of couple relationship education, 59 newlywed couples were randomly assigned to one of two couple relationship programs (CRE): (1) RELATE, which involved receiving feedback mono their relationship based on the on-line RELATE assessment; or (2) RELATE + Couple CARE, which was RELATE plus completing the 6 unit Couple CARE relationship skill training program. Relative to RELATE, RELATE + Couple CARE produced more improvement in couple communication, and high relationship satisfaction across the next 12 months in women. Men sustained high and similar relationship satisfaction in either condition. Skill training CRE has additional benefits for couples …

Puebloan Sites In The Hidden Hills, James R. Allison

Faculty Publications

In 2006 and 2007, the Brigham Young University Archaeological Field School worked in the Hidden Hills area of the Shivwits Plateau, in the western part of the Arizona Strip. The field school mapped, surface collected, and tested a number of Puebloan habitation sites dating from about A.D. 800 to the late 1200s. Architecture includes surface room blocks, stand-alone circular structures, and pit structures, including one deep masonry-lined pit structure that may be a kiva. Ceramic analysis shows that the Hidden Hills residents participated in ceramic exchange networks encompassing other parts of the Arizona Strip as well as more distant places.

A Review Of Fieldworks Language Explorer, Chris Rogers Ph.D.

Faculty Publications

One of the most important goals in language documentation is to produce reference materials as well as to create long-lasting (i.e., archivable) materials for the languages. Fieldworks Language Explorer (FLEx) 3.0 is software for organizing and analyzing linguistic data and is produced for free download by SIL International (SIL)1 . This review has three goals: to show how the current version of FLEx addresses problems in earlier versions of the program, to highlight some of the more useful features of FLEx 3.0, and to indicate how it compares to other database programs.

Cultural And Contextual Differentiation Of Mesoamerican Iconography In The Southwest/Northwest, Michael T. Searcy

Faculty Publications

Ample research has documented the long-term interaction between Mesoamerica and the U.S. Southwest/Northwest Mexico (SW/NW). Nelson (2006:345) has used the phrase "Mesoamerican interaction markers" as a way to describe evidence of this contact in the SW/NW. He further defines these as "a variety of archaeological patterns that are reminiscent of Mesoamerican counterparts" including "objects, practices, and styles." Some of the interaction markers that have been studied at length are trade goods such as copper bells, macaws, shell, and iron pyrite mirrors (Bayman 2002; Bradley 1993; Ericson and Baugh 1993; Kelley 1966, 1995; Mathien 1993; McGuire 1993b; Nelson 2000; Riley 2005). …
