The Infiltration of Hedging and Rising Terminal Pitch in an ASL to English Interpreted Presentation
Get PDFInterpreting from ASL to English requires an interpreter to accurately portray a deaf individual’s character, personality, and language. This representation is accomplished through the language the interpreter uses and their way of speaking. When an interpreter’s own language infiltrates an ASL to English interpretation, this can lead to a misrepresentation of the deaf individual and provide a poor perception by a hearing audience. This research examines common weak language occurrences of hedging (e.g., you know, kind of, so) and rising terminal pitch (ending clauses or statements with an upward inflection). A linguistic analysis of an ASL to English interpretation was conducted to find influencing factors that lead the participant to employ hedging strategies and/or utilize rising terminal pitch within the interpretation. This research impacts current interpreters and interpreter training programs by providing opportunities for further training and intentional practice targeting perceptual challenges caused by hedging and rising terminal pitch. The analysis allows for future research to further assess the influencing factors of an interpreter’s language patterns and the impact had on effectively representing deaf individuals through ASL to English interpreting
Mechanochemistry of Coordination Complexes: Synthesis, Solid-state Photoluminescence, and X-ray Structures
No full textMechanochemical synthetic methods have been employed in chemical reactions dating as far back as the extraction of mercury from cinnabar described by Theophrastus in the fourth century B.C.E. Not only do mechanochemical methods promote principles of green chemistry, including omission of wasteful solvent, but also can provide access to products for which no solution methods have been reported. Additional reaction condition variables with no parallel solution reaction partner allow for additional synthetic control and opportunities for efficient and selective preparations. Our work has focused on mechanochemical preparation of coordination compounds of Earth-abundant transition metals copper and manganese with solid-state photoluminescence for ease of reaction monitoring as well as applications including triboluminescence. Synthesis and characterization of neutral and complex ion salts including X-ray crystallography and solid-state photoluminescence will be presented. Unexpected mechanochemical milling results including scale-up effects and sample history effects will be described in light of the unique features of mechanochemical reactions
Halogen Interactions in Halogenated Oxindoles: Crystallographic and Computational Investigations of Intermolecular Interactions
No full textX-ray structural determinations and computational studies were used to investigate halogen interactions in two halogenated oxindoles. Comparative analyses of the interaction energy and the interaction properties were carried out for Br...Br, C-H...Br, C-H...O and N-H...O interactions. Employing Møller–Plesset second-order perturbation theory (MP2) and density functional theory (DFT), the basis set superposition error (BSSE) corrected interaction energy (Eint(BSSE)) was determined using a supramolecular approach. The Eint(BSSE) results were compared with interaction energies obtained by Quantum Theory of Atoms in Molecules (QTAIM)-based methods. Reduced Density Gradient (RDG), QTAIM and Natural bond orbital (NBO) calculations provided insight into possible pathways for the intermolecular interactions examined. Comparative analysis employing the electron density at the bond critical points (BCP) and molecular electrostatic potential (MEP) showed that the interaction energies and the relative orientations of the monomers in the dimers may in part be understood in light of charge redistribution in these two compounds
