The Impact Of Ballet Techniques On Singing Performers, Julie H. Welch
The Impact Of Ballet Techniques On Singing Performers, Julie H. Welch
Theses and Dissertations
Singing performers are tasked to being a multifaceted artist using their acting and even dance skills in a performance. Voice teachers have long incorporated physical activity into training, but traditional ballet techniques—such as core tension and neck elongation—can contradict healthy singing practices. Given ballet’s deep historical connection to opera and stage performance, this study aims to examine whether integrating ballet into vocal training enhances or hinders a singer’s technique and overall performance. This investigation surveyed forty subjects who identified as teachers, singing performers, or students earning a performance degree and interviewing select subjects for further information; results will be discussed.

Comparing The Effects Of Square, 4-7-8, And 6 Breaths-Per-Minute Breathing Conditions On Heart Rate Variability, Co2 Levels, And Mood, Joshua Marchant
Theses and Dissertations
Background and Hypotheses: Square and 4-7-8 breathing are popularly promoted by psychotherapists but have little empirical support. We hypothesized that breathing at 6 breaths per minute (bpm) would improve HRV, reduce blood pressure, and improve mood more than either square or 4-7-8 breathing. We also hypothesized square and 4-7-8 breathing would increase end-tidal CO2 (PETCO2). Methods: Eighty-four college students (60% female) had HRV measured at baseline and during 1) square breathing, 2) 4-7-8 breathing, 3) 6 bpm with a 4:6 inhale-to-exhale ratio, and 4) 6 bpm with a 5:5 ratio. We used a 3-lead electrocardiogram to measure HRV and a …

Material Classification With Spectropolarimetric Lidar, Alexander J. Watson
Theses and Dissertations
A method for characterizing unknown targets using a hyperspectral polarimetric light detection and ranging (LiDAR) system is presented. Light reflected from manmade objects tends to be more polarized than light reflected from objects in the natural world. As such, polarization measurements can be used in remote sensing applications to differentiate artificial and natural objects. Previous works have attempted to characterize objects through passive polarimetric imagery. Methods developed by Cain and Lemaster and Cunningham facilitate reconstruction of the Stokes Vector from returning light. Martin used multispectral polarimetry to classify targets when the angle of incidence (AOI) is close to 0º. Here, …
