Modeling Of Island Block Scatter For Intensity Modulated Bolus Electron Conformal Therapy, Joseph G. Scotto

LSU Master's Theses

Purpose: Bolus electron conformal therapy (BECT) benefits treatment of the post-mastectomy chest wall, head and neck, paraspinal muscles, and extremities. Patient dose heterogeneities caused by bolus can be reduced through intensity modulation (IM) across the incident electron beam. This requires passive radiotherapy intensity modulation for electrons (PRIME) devices, which utilize tungsten pins (island blocks) imbedded in machinable foam. IM-BECT treatment planning requires accurate dose calculation using the pencil beam redefinition dose algorithm (PBRA). Currently, the PBRA models island blocks as perfect collimators. This work explores models to account for electrons scattering into and out of the sides of island blocks. …

Voice Therapy: Racial Disparities In Adherence And Clinically Significant Outcomes, Amber D. Burks

LSU Master's Theses

Voice therapy is evidence-based, behavioral intervention that can reduce functional and organic voice disorders. Despite its proven effectiveness, non-adherence to voice therapy is still an issue. Research shows that an estimated 65% of patients who initiate voice therapy drop out before reaching therapeutic goals. Voice therapy outcomes are largely dependent on patients’ adherence to treatment regimens, but there is limited information concerning factors that may be associated with voice therapy adherence and therapeutic outcomes for patients who successfully complete voice therapy.

The purpose of this study was to investigate which demographic factors could be associated with higher adherence rates to …

The Quest For Self: Using Mandala Art In Reflective Practice Journaling, Kathleen Quinn

Comparative Woman

This article is a nexus of research, personal journaling reflections, and mandala creation from the authors own journals and focuses on the use of Mandalas as part of a reflective practice journaling process. Attention to mandala usage within reflective practice considering depth interiority, engaging and sharing with others. The authors approach to mandala construction is included followed by an exercise for observation and assessment of mandalas. The structure for reflective practice helps shape transformational leaders, using expressive arts, narratives in journaling. This transformational Discovery pathway and narrative exercises can be used for creating professional learning communities. This form of reflective …

A Single-Subject Study Examining The Effects Of A Behavioral Intervention For Verbal Recurrent Perserveration, Jenifer Juengling-Sudkamp

LSU Doctoral Dissertations

BACKGROUND: Approximately 1 million people in the United States suffer from aphasia and > 50% of those people may demonstrate recurrent perseverations. No consensus has been forthcoming on whether (1) a therapy that directly confronts clients with imminent pre-articulatory automatisms (the perseverations) or (2) a more typical neuropsychological therapy that eschews any direct confrontation with automatic behaviors works best. PURPOSE: The purpose of this study was to determine the treatment efficacy of a non-confrontational picture naming intervention on naming ability in individuals with aphasia and recurrent perseverations. METHODS: This is a prospective single-subject ABAB multiple baseline design replicated across 3 right-handed …
