Description
The purpose of this study was to examine swallowing patterns using ultrasound technology subsequent to the implementation of two therapeutic interventions. Baseline swallow patterns were compared to swallows after implementation of therapeutic interventions common in both feeding therapy (FT) and orofacial myofunctional therapy (OMT). The interventions consist of stimulation of the tongue by z-vibe and tongue pops. Changes in swallowing patterns are described, and similarities of interventions across the two professions are discussed. Ultrasound research in the realm of swallowing is sparse despite having potential clinical application in both professions. In using ultrasound, this study outlines a protocol for utilization of a hand-held probe and reinforces a particular protocol described in the literature. Real-time ultrasound recordings of swallows for 19 adult female subjects were made. Participants with orofacial myofunctional disorder are compared to a group with typical swallowing and differences in swallowing patterns are described. Three stages of the oral phase of the swallow were assigned based on ultrasonic observation of the tongue shape. Analysis involves total duration of the swallow, duration of the three stages in relation to the total duration of the swallow, and the number of swallows required for the bolus to be cleared from the oral cavity. No significant effects of either intervention were found. Swallowing patterns showed a general trend to become faster in total duration subsequent to each intervention. An unexpected finding showed significant changes in the relationship between the bolus preparation stage and the bolus transportation stage when comparing the group classified as having a single swallow and the group classified as having multiple swallows.

Description
Despite the vast research and attention given to education, little is known about teacher preparation to raise the quality of education for the honors students. There is an apparent disconnect from the honors students at Arizona State University and the education major. This study uncovers the perspective of the honors students who are majoring in education. Qualitative data was collected using one-on-one interviews. Results showed that all seven interviewed subjects were not satisfied with the education they were receiving as an honors education major.

Description
This thesis is a two-part theatre and literature project on The Importance of Being Earnest by Oscar Wilde. The research component will consist of gathering information from the origins of this play in writing and in production to further understand my knowledge of the time it was written in and how it has been interpreted over the years. The theatrical elements will come as I direct and produce my own production of the play, and compare my research of Wilde's play and past productions to my own directorial decisions in attempt to make a successful student performed play.

Description
Research on /r/ production previously used formant analysis as the primary acoustic analysis, with particular focus on the low third formant in the speech signal. Prior imaging of speech used X-Ray, MRI, and electromagnetic midsagittal articulometer systems. More recently, the signal processing technique of Mel-log spectral plots has been used to study /r/ production in children and female adults. Ultrasound imaging of the tongue also has been used to image the tongue during speech production in both clinical and research settings. The current study attempts to describe /r/ production in three different allophonic contexts; vocalic, prevocalic, and postvocalic positions. Ultrasound analysis, formant analysis, Mel-log spectral plots, and /r/ duration were measured for /r/ production in 29 adult speakers (10 male, 19 female). A possible relationship between these variables was also explored. Results showed that the amount of superior constriction in the postvocalic /r/ allophone was significantly lower than the other /r/ allophones. Formant two was significantly lower and the distance between formant two and three was significantly higher for the prevocalic /r/ allophone. Vocalic /r/ had the longest average duration, while prevocalic /r/ had the shortest duration. Signal processing results revealed candidate Mel-bin values for accurate /r/ production for each allophone of /r/. The results indicate that allophones of /r/ can be distinguished based the different analyses. However, relationships between these analyses are still unclear. Future research is needed in order to gather more data on /r/ acoustics and articulation in order to find possible relationships between the analyses for /r/ production.

Description
Colleges and universities have goals and strategies in place to fill their on-campus housing facilities with students. At Arizona State University (ASU), the goal is to fill every bedspace on campus. All first-year students are expected to live on campus their first year at ASU. In Barrett, the Honors College (BHC), students are expected to live on-campus their first and second year at ASU. This study explores the BHC upperdivision communities to better understand why students are not returning to live on campus beyond the two-year live-on expectation. In this study, the researcher created a website to better inform students of the renewal process and the benefits of living on-campus. More than 200 BHC upperdivision students participated in this study through interviews and surveys. Quantitative results of the study indicated a positive and significant correlation between students who believe it costs less to live on campus, enjoy living on campus, interact with faculty and staff outside of the classroom with intent to live on campus the next academic year. Students who felt their currently living situation had a positive impact on their overall emotional/mental wellbeing, feel a sense of community or connection to others, and feel more connected because they live on campus are more likely to intend to live on campus. Students who were surveyed after the implementation of the renewal website believed it cost less to live on campus than off campus, felt that it was easier to navigate the application, and felt that they had a better understanding of the renewal process. Qualitative results of the study indicated students were deciding to live off campus due to the limited room options and the cost of on-campus housing. Students did not feel that there was a sense of community in BHC upperdivision housing, but they did feel like living on-campus was convenient and opened opportunities to get involved. The renewal website did not have an effect on students’ behavior, knowledge and intent to renew housing, and the renewal process was easy to navigate for some of the participants and difficult to navigate for the other participants.
