Vocal Hygiene for Musical Theatre Performers

There have been numerous “do’s - and - don’t’s” vocal hygiene pamphlets made for voice users, however, a guide for vocal hygiene for musical theatre performers is not typically included in these pamphlets. Musical theatre performers differ from other professional voice users, because in addition to singing, they also have the taxing responsibilities of acting and dancing. As a result, many musical theatre performers have questions and often seem confused about what proper vocal hygiene should be for them. The goal of this honors project was to create an advisory brochure on vocal hygiene specifically for musical theatre performers. This brochure is based upon information published by professionals from various disciplines such as medicine, speech-language pathology, music, and theatre. This brochure addresses a number of aspects that musical theatre performers should be aware of as a result of the many demands that are placed upon them. This resulted in the following categories for the creation of the brochure: preventing overuse, medical care, nutrition/hydration, environmental factors, and utilizing proper technique. The background information and sources for this project are found in the annotated bibliography at the end of this paper

Vocal Fry: Acoustics, Airflow, and EGG Analysis of Various Types

Objective: Current studies on vocal fry at BGSU involve categorizing various types of vocal fry production (Proctor et al., 2019 ASHA conference). The objective of the current study was to characterize vocal fry types using acoustic, airflow, and electroglottographic measures. Such characterization should shed light on the physiological production of vocal fry and potential clinical understanding and intervention. Methods/design: Three men and three women, 18-22 years old, read the Rainbow passage as well as spoke conversationally and spontaneously in a sound treated booth. The participants spoke using a microphone and an EGG system (Kay Model 6103), as well as with and without the use of a face mask (Glottal Enterprises MSIF-2 system). The participants were asked to speak normally. There was no mention of vocal fry to them. Results: A number of the categories of vocal fry were found in the corpus (e.g., single pulses, double pulses, multiple pulses, period doubling, delayed fry). Also the corpus included interesting results for rough voice and aperiodic segments. The figure below shows an example of period doubling. The laryngeal aspect shows a range of glottal closing and opening secondarily to the primary glottal closing and opening (the bottom EGG signal), both occurring in the period of two normal cycles (shown to the left). This example is similar to almost all others in the sense that the glottal activity typically follows the wideband airflow activity (middle trace) as well as the acoustic signal (top trace). Conclusions: The study emphasizes the reality of the laryngeal function in the production of vocal fry, wherein the acoustic transients and various timing of glottal pulses can be seen in all three signals (acoustic, airflow, glottographic). This suggests that the primary cause of vocal fry is laryngeal, but seen and heard as sequences of transients both acoustic and aerodynamic

Robust Digital Holography For Ultracold Atom Trapping

We have formulated and experimentally demonstrated an improved algorithm for design of arbitrary two-dimensional holographic traps for ultracold atoms. Our method builds on the best previously available algorithm, MRAF, and improves on it in two ways. First, it allows for creation of holographic atom traps with a well defined background potential. Second, we experimentally show that for creating trapping potentials free of fringing artifacts it is important to go beyond the Fourier approximation in modelling light propagation. To this end, we incorporate full Helmholtz propagation into our calculations.Comment: 7 pages, 4 figure

Reconstructing ‘the Alcoholic’: Recovering from Alcohol Addiction and the Stigma this Entails

Public perception of alcohol addiction is frequently negative, whilst an important part of recovery is the construction of a positive sense of self. In order to explore how this might be achieved, we investigated how those who self-identify as in recovery from alcohol problems view themselves and their difficulties with alcohol and how they make sense of others’ responses to their addiction. Semi-structured interviews with six individuals who had been in recovery between 5 and 35 years and in contact with Alcoholics Anonymous were analysed using Interpretative Phenomenological Analysis. The participants were acutely aware of stigmatising images of ‘alcoholics’ and described having struggled with a considerable dilemma in accepting this identity themselves. However, to some extent they were able to resist stigma by conceiving of an ‘aware alcoholic self’ which was divorced from their previously unaware self and formed the basis for a new more knowing and valued identity

Development and evaluation of a quality score for abstracts

BACKGROUND: The evaluation of abstracts for scientific meetings has been shown to suffer from poor inter observer reliability. A measure was developed to assess the formal quality of abstract submissions in a standardized way. METHODS: Item selection was based on scoring systems for full reports, taking into account published guidelines for structured abstracts. Interrater agreement was examined using a random sample of submissions to the American Gastroenterological Association, stratified for research type (n = 100, 1992–1995). For construct validity, the association of formal quality with acceptance for presentation was examined. A questionnaire to expert reviewers evaluated sensibility items, such as ease of use and comprehensiveness. RESULTS: The index comprised 19 items. The summary quality scores showed good interrater agreement (intra class coefficient 0.60 – 0.81). Good abstract quality was associated with abstract acceptance for presentation at the meeting. The instrument was found to be acceptable by expert reviewers. CONCLUSION: A quality index was developed for the evaluation of scientific meeting abstracts which was shown to be reliable, valid and useful

Cross validation of bi-modal health-related stress assessment

This study explores the feasibility of objective and ubiquitous stress assessment. 25 post-traumatic stress disorder patients participated in a controlled storytelling (ST) study and an ecologically valid reliving (RL) study. The two studies were meant to represent an early and a late therapy session, and each consisted of a "happy" and a "stress triggering" part. Two instruments were chosen to assess the stress level of the patients at various point in time during therapy: (i) speech, used as an objective and ubiquitous stress indicator and (ii) the subjective unit of distress (SUD), a clinically validated Likert scale. In total, 13 statistical parameters were derived from each of five speech features: amplitude, zero-crossings, power, high-frequency power, and pitch. To model the emotional state of the patients, 28 parameters were selected from this set by means of a linear regression model and, subsequently, compressed into 11 principal components. The SUD and speech model were cross-validated, using 3 machine learning algorithms. Between 90% (2 SUD levels) and 39% (10 SUD levels) correct classification was achieved. The two sessions could be discriminated in 89% (for ST) and 77% (for RL) of the cases. This report fills a gap between laboratory and clinical studies, and its results emphasize the usefulness of Computer Aided Diagnostics (CAD) for mental health care
