An Exploration Of Swallowing Stimulation In The Infant, Sarah Elizabeth Hegyi
Dissertations, 2014-2019
The purpose of this study was twofold: to determine the effects of two types of non-invasive, peripheral sensory stimulation on the frequency of infant swallowing and to explore the cortical activation patterns in response to stimulation in the somatosensory and motor regions of the brain during infancy, between 2-4 months and 7-9 months of age. The two different forms of mechanical stimulation investigated include pacifier stimulation to the lips and oral cavity and vibrotactile stimulation via the external throat area to the laryngeal tissues. The study represents a prospective, repeated experimental research design. Investigators utilized an accelerometer and an inductive …

Nonresponse Bias In Online Course Evaluations, Cassandra Jones
Nonresponse Bias In Online Course Evaluations, Cassandra Jones
Dissertations, 2014-2019
Recently more universities have started administering course evaluations online. With the process no longer in the classroom, some students decide not to complete their course evaluations during their own time, resulting in concerns about online course evaluation results being biased because of lack of response. This study examined course evaluation results at a small diverse mid-Atlantic Catholic university. A cross-classified random effects model was used to capture student responses across all of their courses. Nonresponse bias was examined by determining predictors of online course evaluation ratings and participation. Variables predicting both participation and ratings were considered to be a potential …

The Increasing Rate Of Undergraduate Male Attrition: What The Men Tell Us. A Qualitative Case Study., Monika Neelam Kushwaha
Dissertations, 2014-2019
The current study explores the factors that may contribute to undergraduate male attrition and ways of improving retention at James Madison University (JMU) using qualitative case study methodology. Semi-structured interviews were conducted with five men who were currently enrolled at JMU, six men who had previously been enrolled at JMU but who had left before completing a degree, and two university administrators who work closely with students at risk of dropping out. Interviews were recorded and transcribed. They were analyzed using QSR’s N-Vivo 9, a qualitative data management software package. Themes and sub-themes emerged around two major categories: factors that …
Examining The Bricks And Mortar Of Socioeconomic Status: An Empirical Comparison Of Measurement Methods, Ross Markle
Examining The Bricks And Mortar Of Socioeconomic Status: An Empirical Comparison Of Measurement Methods, Ross Markle
Dissertations, 2014-2019
The impact of socioeconomic status (SES) on educational outcomes has been widely demonstrated in the fields of sociology, psychology, and educational research. Across these fields however, measurement models of SES vary, including single indicators (parental income, education, and occupation), multiple indicators, hierarchical models, and most often, an SES composite provided by the National Center for Educational Statistics. This study first reviewed the impact of SES on outcomes in higher education, followed by the various ways in which SES has been operationalized. In addition, research highlighting measurement issues in SES research was discussed. Next, several methods of measuring SES were used …
Comparison Of Speech Intelligibility Over The Telephone Using A Hearing Aid Micorphone And Telecoil, Phillip K. Bond
Comparison Of Speech Intelligibility Over The Telephone Using A Hearing Aid Micorphone And Telecoil, Phillip K. Bond
Dissertations, 2014-2019
The purpose of the current study is to determine if the smaller, modern hearing aid has affected the speech intelligibility over the telephone using a telecoil and hearing aid microphone. Six hearing impaired listeners were situated in a quiet office and were asked to repeat aloud Connected Speech Sentences (CST) they heard through the telephone while wearing their hearing aid in telecoil only mode, microphone only mode, and without their hearing aid. The CST sentences were presented in three different signal-to-noise ratios (Quiet, +10dB, & +5dB) with the recorded speech babble of the CST test. It was discovered that the …
Objective And Subjective Evaluation Of Wind Noise Reduction In Digital Hearing Aids, Sheena Kate Jessee
Objective And Subjective Evaluation Of Wind Noise Reduction In Digital Hearing Aids, Sheena Kate Jessee
Dissertations, 2014-2019
Wind noise is problematic for hearing aid users who enjoy outdoor activities. Not only is it annoying, it can create distortion by overloading the microphone and masking signals that hearing aid users desire to hear. Some hearing aid manufacturers offer wind noise reduction in addition to general noise reduction (WNR + NR) for clinicians to manipulate in their software. This study compares objective and subjective measures of wind noise reduction as well as subjective measure of intelligibility obtained using various hearing aid manufacturers and noise reduction settings while HINT sentences were played in the presence of constantly generated wind. Significant …
The Effect Of Kalman Weighted Filtering And In-Situ Pre-Amplification On The Accuracy And Efficiency Of Abr Threshold Estimation, Julie Kathleen Wheeler
The Effect Of Kalman Weighted Filtering And In-Situ Pre-Amplification On The Accuracy And Efficiency Of Abr Threshold Estimation, Julie Kathleen Wheeler
Dissertations, 2014-2019
Auditory brainstem responses (ABRs) are important for acquiring frequency specific information for determination of the degree and type of hearing loss for infants and difficult-to-test populations when behavioral audiometry cannot be carried out. This study investigated the effects of Kalman weighted filtering and in-situ pre-amplification employed by the Vivosonic Integrity V500 ABR system on threshold accuracy and efficiency in an environment of high physiologic noise in comparison to a conventional ABR system which employs a standard artifact rejection paradigm. Auditory brainstem responses were collected using the Vivosonic ABR system and a conventional ABR system both in quiet and in noise …
Effects Of Speech Signal Type And Attention On Acceptable Noise Level In Elderly, Hearing-Impaired Listeners, Jennifer Susan Mundorff
Effects Of Speech Signal Type And Attention On Acceptable Noise Level In Elderly, Hearing-Impaired Listeners, Jennifer Susan Mundorff
Dissertations, 2014-2019
The primary objective of this study was to determine if acceptable noise levels (ANLs) in elderly, hearing-impaired listeners were dependent on speech intelligibility and listener attention levels. Acceptable noise levels (ANLs), expressed in decibels, is defined as the maximum background noise level that is acceptable while listening to and following a story. Connected speech test (CST) sentences were recorded with clear speech, conversational speech and temporally altered, fast-rate speech. Thirty-five, elderly, hearing-impaired individuals (61-97 years, M=75) with symmetrical, bilateral sensorineural hearing loss participated. Most comfortable listening levels (MCL) and background noise level (BNL) measurements were completed for each speech stimulus …
Introducing The Unified Measure Of University Mattering: Instrument Development And Evidence Of The Structural Integrity Of Scores For Transfer And Native Students, Megan Katharine France
Introducing The Unified Measure Of University Mattering: Instrument Development And Evidence Of The Structural Integrity Of Scores For Transfer And Native Students, Megan Katharine France
Dissertations, 2014-2019
The psychological construct university mattering is defined as the feeling that one makes a difference and is significant to his or her university’s community. University mattering emerged from the theory of general mattering, which describes mattering as a complex construct consisting of the facets awareness, importance, ego-extension and reliance. The Revised University Mattering Scale (RUMS), created by writing items to represent these facets, was developed for use in the current study. The purpose of this study was twofold. First, the model-data fit of the RUMS was evaluated using confirmatory factor analysis (CFA). Five a priori models were tested using two …
Development And Validation Of The Preservice Mathematical Knowledge For Teaching Items (Pmkt): A Mixed-Methods Approach, Javarro Antoine Russell
Development And Validation Of The Preservice Mathematical Knowledge For Teaching Items (Pmkt): A Mixed-Methods Approach, Javarro Antoine Russell
Dissertations, 2014-2019
Mathematical knowledge for teaching (MKT) is the knowledge required for teaching mathematics for understanding. Researchers suggest that this construct consists of multiple knowledge domains. Those domains include teachers’ knowledge of mathematical content and knowledge about teaching mathematics. These domains of MKT have been theoretically and empirically examined to determine their effects on K-12 student achievement. However, empirical evidence of this relationship is limited due to a lack of measures to assess MKT. Recently, researchers have constructed measures of MKT to evaluate the effectiveness of professional development activities with in-service teachers. These measures, however, lack validity evidence for use in teacher …
The Evolution Of Style In The Neoclassical Works Of Stravinsky, Kyle Szabo
The Evolution Of Style In The Neoclassical Works Of Stravinsky, Kyle Szabo
Dissertations, 2014-2019
The compositional output of Igor Stravinsky is roughly divided into three periods: Russian, Neoclassical, and Serial. In his neoclassical period of composition, Stravinsky developed highly refined methods of formal construction, harmonic management, and use of counterpoint. Careful analysis of several neoclassical and transitional works serves to demonstrate Stravinsky’s innovative methods of voice leading, economy of pitch class set material, and ingenuity in redefining Classical era forms. Stravinsky’s Russian ballets are stylistically focused on practical and stage-oriented formal structures, stratified counterpoint, and thematic content originating in folk materials. As he began writing more concert music, the extraction of these stylistic elements …
An Evaluation Of A New Method Of Irt Scaling, Shelley Ragland
An Evaluation Of A New Method Of Irt Scaling, Shelley Ragland
Dissertations, 2014-2019
In order to be able to fairly compare scores derived from different forms of the same test within the Item Response Theory framework, all individual item parameters must be on the same scale. A new approach, the RPA method, which is based on transformations of predicted score distributions was evaluated here and was shown to produce results comparable to the widely used Stocking-Lord (SL) method under varying conditions of test length, number of common items, and differing ability distributions in a simulation study. The new method was also examined using actual student data and a resampling analysis. Both the simulation …
Effect Of Real-Ear Verification On Hearing Aid Benefit, Sarah K. Sporck
Effect Of Real-Ear Verification On Hearing Aid Benefit, Sarah K. Sporck
Dissertations, 2014-2019
Real-ear measurements have been proven to be the most accurate measure of hearing aid verification. However, many audiologists find real-ear to be too time consuming to use consistently. One popular reason for underutilizing real-ear verification is the use of first fitting algorithms provided on manufacturer programming software. However, the predicted fittings provided on the software are not an accurate means of providing what is recommended by popular prescriptive formulas (Hawkins and Cook, 2003; Aarts and Caffee, 2005). The main reason for this discrepancy is that the software does not take into account individual anatomical differences, i.e. ear canal volume and …
Franz Liszt: The Sonata In B Minor As Spiritual Autobiography, Jonathan David Keener
Franz Liszt: The Sonata In B Minor As Spiritual Autobiography, Jonathan David Keener
Dissertations, 2014-2019
Many composers, particularly in the 19th century, have attempted to write “autobiographical” music. Although Franz Liszt never explicitly mentioned that any of his works were autobiographical, the facts we have about his life and the symbolism within his Sonata in B Minor suggest that this piece may serve this purpose, either intentionally or subconsciously. Liszt, having strong ties to the Catholic Church, may have also consciously or unconsciously incorporated religious symbolism into the work. Works that exerted influence on the formal structure and the possible extra-musical meaning of the Sonata in B Minor include Charles-Valentine Alkan’s Grande Sonate, Robert …
