Numerical Investigation Of Subglottal Stenosis Effects On Human Voice Production, Dariush Bodaghi

Electronic Theses and Dissertations

This dissertation aimed to advance knowledge of how subglottal stenosis impacts voice production physiology. An in-house fluid-structure-acoustic interaction approach based on the hydrodynamic/acoustic splitting technique was employed. This technique was rigorously verified for simulating phonation by matching the acoustic behavior to a compressible flow solver for phonation-relevant geometries. Simulations of an idealized 2D vocal tract model demonstrated the effects of supraglottal acoustic resonance on vocal fold kinematics and glottal flow waveform. Results showed that the acoustic coupling between higher harmonics and formats generated pressure oscillations, modifying vocal fold dynamics and glottal flow rate.

A major novelty was the incorporation and …

On-Campus Mental Health Service Use Among College Students With Autism: A Case Study Applying The Andersen Behavioral Model Of Health Services Use, Estella C. Lilyquist

Electronic Theses and Dissertations

The unique set of impairments and limitations presented by students with autism spectrum disorder (ASD) make the accessing of campus-based nonacademic resources more difficult and complicated than their typically developed peers. Each year, the rate of students entering college with disabilities continues to grow, but their mental well-being is relatively poor. The purpose of this qualitative case study was to apply the conceptual framework of the Andersen behavioral model of health services use (ABMHSU) to the experiences of college students with ASD to understand and predict their utilization of campus-provided mental health resources. The participants were seven college students with …

The Relationship Between Social Cognition And Social Behavior Of Young Adults With Autism Spectrum Disorder Using The Ucla Peers® For Young Adults Social Skill Program, Meaghan Balsdon

Electronic Theses and Dissertations

Research indicates that social communication impairments are a defining and persistent feature of Autism Spectrum Disorder (ASD; Centers for Disease Control and Prevention, 2022). Social communication consists of what an individual knows about social skills (i.e., social cognition) and how they observably respond in social situations (i.e., social behavior). It is difficult to gain a comprehensive assessment of social communication because social cognition assessments are prone to inaccuracies due to poor metacognitive skills in individuals with ASD (DeBrabander et al., 2021; Cederlund et al., 2010; Vickerstaff et al., 2006). Inaccurate reporting of social cognition leads to potential discrepancies in observable …

Parents' Perception Of Speech-Language Pathologists In Secondary Transition, Madelyn Hunt

Electronic Theses and Dissertations

Speech-Language Pathologists provide services to youth with Down syndrome. The purpose of this study was to (a) determine if parents are aware that speech-language pathologists can provide services to prepare their children for secondary transition; (b) identify the parents’ perceptions of the services provided by speech-language pathologists; and (c) determine if in the parents’ opinion, the speech-language pathologist provided a vital role in preparing their child for transition. Using nonprobability snowball sampling, this cross-sectional mixed-method survey study included 85 parents of youth (ages 14-22) with Down syndrome across the United States. Parents rated their experiences and described their beliefs and …

Speech-Language Pathologists’ Barriers To Providing Services To The Deaf And Hard Of Hearing Children Ages 2–9, Irene S. García-Benavides

Electronic Theses and Dissertations

This qualitative case study explored the knowledge and experiences of 12 speech-language pathologists (SLPs) regarding the culture and linguistic processes of the Deaf culture when assessing and treating deaf and hard of hearing children ages 2 to 9. Data analysis has resulted in identification of the following main themes: (a) The Scope of Practice, (b) Barriers Regarding Culturally and Linguistically Informed Practices, and (c) Awareness of Similarities and Differences in Language Acquisition and Structures in English and American Sign Language (ASL). The findings of this study underscored the importance of knowledge that SLPs have to acquire in order to provide …
