Voice Use

This field-based case study documented students’ ( N = 256) voice use and voice health perceptions during a 3-day all-state high school chorus event through daily surveys, phonation duration data, analysis of rehearsal voice use behaviors, and field notes. Among the primary results are the following: (a) First and final day survey comparisons indicated significant declining changes in 5 of 7 voice health indicator statements and in self-perceptions of singing voice quality, yet (b) most students (78.8%) believed they had taken good care of their voices; (c) self-reported sleep hours decreased significantly; (d) vocal fold contact time measured with two students ranged from 15% to 38% during rehearsal periods, 1% to 27% during on-site non-rehearsal times, and 3% to 17% during measured pre- and post-event activities, but (e) overall percentages of vocal fold contact varied little between regular rehearsal and on-site non-rehearsal events (female: 19.37% rehearsal, 20.11% non-rehearsal; male: 22.89% rehearsal, 20.54% non-rehearsal); (f) rehearsal voice rest time (63%) exceeded voice use time (37%); (g) students sat in close proximity to other choristers for approximately 73% of rehearsal time; and (h) the two compositions ranked highest relative to demands on adolescent voices consumed 61% of rehearsal time.

Voice Use

PurposeVocal fold motion impairment (VFMI) can be the result of iatrogenic or traumatic injury or may be idiopathic in nature. It can result in glottic incompetence leading to changes in vocal quality and ease. Associated voice complaints may include breathiness, roughness, diplophonia, reduced vocal intensity, feeling out of breath with talking, and vocal fatigue with voice use. A comprehensive interprofessional voice evaluation includes auditory-perceptual voice evaluation, laryngeal examination including videostroboscopy, acoustic and aerodynamic voice measures. These components provide valuable insight into laryngeal structure and function and individual voice use patterns and, in conjunction with stimulability testing, help identify candidacy for voice therapy and choice of therapeutic techniques.ConclusionA comprehensive, interprofessional evaluation of patients with VFMI is necessary to assess the role of voice therapy and develop a treatment plan. Although there is no efficacy data to support specific voice therapy techniques for treating VFMI, considerations for various techniques are provided.

Empirical Means

Christopher Ballantine’s focus is on timbre, in particular the timbre of the singing voice, and how this combines with the imagination to create meaning. His investigation is largely philosophical; but the growth in popularity of opera in post-apartheid South Africa provides empirical means for Ballantine to indicate this powerful but analytically neglected way of creating meaning in the performance of music. His case study shows how timbre can produce musical experiences that have a particular, and often surprising, resonance. Through interviews with leading figures in South African opera, Ballantine demonstrates that timbre is a vital wellspring of imagined meaning; it should especially be seen thus if we seek to understand the singing voice in a sociopolitical context such as that of South Africa during and after apartheid.

Voice Use

Objective: This study explores the immediate impact of prolonged voice use by professional sports coaches. Method: Speech samples including sustained phonation of vowel /a/ and a short read passage were collected from two professional sports coaches. The audio recordings were made within an hour before and after a coaching session, over three sessions. Perceptual evaluation of voice quality was done using the GRBAS scale. The speech samples were subsequently analyzed using Praat. The acoustic measures included fundamental frequency (f0), jitter, shimmer, Harmonics-to-Noise ratio and Cepstral Peak Prominence. Main results: The results of perceptual and acoustic analysis suggest a slight shift towards a tenser phonation post-coaching session, which is a likely consequence of laryngeal muscle adaptation to prolonged voice use. This tendency was similar in sustained vowels and connected speech. Conclusion: Acoustic measures used in this study can be useful to capture the voice change post-coaching session. It is desirable, however, that more sophisticated and robust and at the same time intuitive and easy-to-use tools for voice assessment and monitoring be made available to clinicians and professional voice users.

Volunteer Coaches

This study utilizes structuration theory to reveal how volunteer coaches in an all-female youth sport program describe barriers and agency to their organizational mission of athlete empowerment. The dataset in this ethnographic case study comes from volunteer coaching experiences within two youth sport teams. Ethnographic data included field notes from four volunteer coaches, collaborative interviews, archival organizational documents, as well as athlete and parent interviews. A qualitative analysis, informed by structuration theory, revealed specific legitimate, dominant, and symbolic structures that enabled and constrained volunteer and youth athlete empowerment within the teams. The analysis also revealed a process of mirroring empowerment, a novel theoretical concept, which describes how athletes reflected back their own empowerment to empower volunteer coaches. Theoretical and practical implications of the findings are discussed.

The Military

International law dictates that actors in armed conflicts must distinguish between combatants and civilians. But how do legal actors assess the legality of a military operation after the fact? I analyze a civil proceeding for compensation by victims of a German-led airstrike in Afghanistan. The court treated military video as key evidence. I show how lawyers, judges, and expert witnesses categorized those involved by asking what a “military viewer” would make of the pictures. During the hearing, they avoided the categories of combatants/civilians; the military object resisted legal coding. I examine the decision in its procedural context, using ethnographic field notes and legal documents. I combine two ethnomethodological analytics: a trans-sequential approach and membership categorization analysis. I show the value of this combination for the sociological analysis of legal practice. I also propose that legal practitioners should use this approach to assess military viewing as a concerted, situated activity.

Pre Service Teacher

Inquiry has been the framework for guiding reform-based science instruction. All too often, the role of technology is treated tacitly without contributions to this framework. This case study examines a collection of pre-service teachers enrolling in two educational technology courses and the role these experiences play in promoting inquiry teaching. Interviews, field notes, surveys, reflective digital narratives and student-generated exhibits served as the data informing the analysis of inquiry experiences which shaped the enacted lessons of science teachers. Implications for research and practices are discussed.Keywords: teacher reflection; science education; technologyCitation: Research in Learning Technology 2014, 22: 21691 - http://dx.doi.org/10.3402/rlt.v22.21691

Reflexive Analysis

Research-practice partnerships (RPPs) offer promising approaches to improve educational outcomes. Navigating boundaries between contexts is essential for RPP effectiveness, yet much work remains to establish a conceptual framework of boundary spanning in partnerships. Our longitudinal comparative case study draws from our experiences as graduate student boundary spanners in three long-term partnerships to examine boundary spanning roles in RPPs, with particular attention to the ways in which power permeates partnership work. Using qualitative, critically reflexive analysis of meeting artifacts and field notes, we found that our boundary spanning roles varied along five spectrums: institutional focus, task orientation, expertise, partnership disposition, and agency. Our roles were shaped by the organizational, cultural, relational, and historical features of the partnerships and contexts of interaction. We aim to promote the development of effective RPP strategies by leveraging the perspectives and positionality of graduate students in order to advance understanding of boundary spanning roles.
