Communication About End Of Life For Patients Living With Amyotrophic Lateral Sclerosis: A Scoping Review Of The Empirical Evidence, Shelagh K. Genuis, Westerly Luth, Sandra Campbell, Tania M. Bubela, Wendy S. Johnston

Office of the Provost

Background: Communication about end of life, including advance care planning, life-sustaining therapies, palliative care, and end-of-life options, is critical for the clinical management of amyotrophic lateral sclerosis patients. The empirical evidence base for this communication has not been systematically examined.
Objective: To support evidence-based communication guidance by (1) analyzing the scope and nature of research on health communication about end of life for amyotrophic lateral sclerosis; and (2) summarizing resultant recommendations.
Methods: A scoping review of empirical literature was conducted following recommended practices. Fifteen health-related and three legal databases were searched; 296 articles were screened for inclusion/exclusion criteria; and quantitative …

An Examination Of Selected Vowel Structures Of Three Generations Of Native Appalachian English Speakers, Melinda L. Richards

Doctoral Dissertations

Appalachian English (AppE) is a relic dialect, until recently considered to be resistant to change due to the relative isolation of its speakers. AppE may have become an “endangered dialect,” much in the same manner as other insular dialects such as those spoken on Ocracoke Island, Smith Island, and the Sea Islands (Wolfram & Schilling-Estes, 1995; Wolfram & Schilling-Estes, 1998). The purpose of this investigation was to answer two research questions: (1) Are there significant cross-generational differences in the production of eight selected vowels during conversational speech, and (2) Are there significant cross-generational differences in the degree to which speakers …

Minimum Mean Square Error Spectral Peak Envelope Estimation For Automatic Vowel Classification, Jaishree Venugopal

Electrical & Computer Engineering Theses & Dissertations

Spectral feature computations continue to be a very difficult problem for accurate machine recognition of speech. In this work, which focuses on vowels, a new spectral peak envelope method for vowel classification is developed, based on a missing frequency components model of speech recognition. According to the missing frequency components model, vowel recognition depends only on the spectral (harmonic) peaks. Smoothing and interpolation of the spectra, performed in the standard cepstral analysis method commonly used in automatic speech recognition, actually loses valuable information and results in reduced recognition accuracy. The new method for feature extraction presented in this thesis is …

The Description And Comparison Of Feature Retention Patterns For Children With Phonological Impairment Developmental Apraxia Of Speech And Typically Developing Children., Amanda N. Lambert

Electronic Theses and Dissertations

The purpose of the present study was to compare feature retention patterns between children developing speech typically (TD) and children with phonological impairment (PI) and to discuss these findings in terms of characteristics, severity, and implication for the identification of developmental apraxia of speech (DAS). A second purpose was to determine if a relationship exists between phonological knowledge and feature retention.

This study consisted of a PI group and a TD group of children, ages four to six. A 245-item speech sample was collected from each subject. Feature retention percentages as well as percent correct underlying representation (PCUR) were calculated …

Phonological Intervention Using A Multiple Opposition Approach, A. Lynn Williams, John Kalbfleisch

ETSU Faculty Works

The purpose of this investigation was to examine phonological restructuring when contrastive oppositions were constructed to include larger treatment sets that confronted the child with multiple sound targets selected from an entire rule set.
