Education and Prevention: An Open Communication Against the Sexual Abuse and Grooming of Adolescents
Description
With the assistance of my thesis committee, I created a podcast to fulfill my objective of interviewing survivors of sexual abuse/grooming practices and their support systems. I utilized this method to have in-depth discussions and provide people with a safe space to share their experiences. By doing so, we were able to reflect on the areas in which professionals can improve on recognizing signs of abuse in their communities. My goal was to show how training teachers to recognize signs of trauma is essential for effectively assisting the population we serve. Ultimately, this came down to what instruction was taught in the Teachers College. Curricula centered on properly managing trauma in the classroom, including sexual abuse, should be required for courses in the upper and lower division degree program for Mary Lou Fulton Teachers College.

Callithrix jacchus, also known as a common marmoset, is native to the new world. These marmosets possess a wide range of vocal repertoire that is interesting to observe for the purpose of understanding their group communication and their fight or flight responses to the environment around them. In this project, I am continuing with the project that a previous student, Jasmin, had done to find more data for her study. For the most part, my project entailed recording and labeling the marmoset’s calls into different types.

Description
Speech intelligibility measures how much a speaker can be understood by a listener. Traditional measures of intelligibility, such as word accuracy, are not sufficient to reveal the reasons of intelligibility degradation. This dissertation investigates the underlying sources of intelligibility degradations from both perspectives of the speaker and the listener. Segmental phoneme errors and suprasegmental lexical boundary errors are developed to reveal the perceptual strategies of the listener. A comprehensive set of automated acoustic measures are developed to quantify variations in the acoustic signal from three perceptual aspects, including articulation, prosody, and vocal quality. The developed measures have been validated on a dysarthric speech dataset with various severity degrees. Multiple regression analysis is employed to show the developed measures could predict perceptual ratings reliably. The relationship between the acoustic measures and the listening errors is investigated to show the interaction between speech production and perception. The hypothesize is that the segmental phoneme errors are mainly caused by the imprecise articulation, while the sprasegmental lexical boundary errors are due to the unreliable phonemic information as well as the abnormal rhythm and prosody patterns. To test the hypothesis, within-speaker variations are simulated in different speaking modes. Significant changes have been detected in both the acoustic signals and the listening errors. Results of the regression analysis support the hypothesis by showing that changes in the articulation-related acoustic features are important in predicting changes in listening phoneme errors, while changes in both of the articulation- and prosody-related features are important in predicting changes in lexical boundary errors. Moreover, significant correlation has been achieved in the cross-validation experiment, which indicates that it is possible to predict intelligibility variations from acoustic signal.
