Perception Of Performance

We investigated how the attractiveness bias that influences the judgment of a variety of characteristics and behaviors in infants, children, and adults affects the evaluation of young pianists' performances. The assumption was that both the visual and the audio components of a videotaped musical performance influence the viewers perception of performance quality. We asked children, musicians, and nonmusicians (n = 75) to rate the quality of 10 piano performances from audiotapes (sound only) and from videotapes (sound and image). Additionally, the participants rated the attractiveness of the performers from brief videos of the performers getting ready to play. Results show that evaluations of audiovisual recordings of musical performances are judged more reliably than are audio recordings but also suggest that they may be affected by an attractiveness bias. The bias was found to favor the more attractive pianists among the female performers and among the best players, and the less attractive pianists among the male performers. The decision to use more reliable means of evaluation (videotapes or DVDs) at the expense of favoring a particular group of performers would have to be taken carefully depending on the outcomes of the situation.

Applause, an overt expression of approval from audience to performer, is one of the most common forms of audience response to live musical performances. In this study, we examined the effects of applause magnitude (high, low, or no applause) and musical style (motet or spiritual) on listeners’ ratings of choral performances. A secondary area of interest was the degree to which these effects might differ between music majors and non-music majors. University singers ( N = 117) listened to six excerpts recorded by a university choral ensemble and rated the performance quality of each excerpt. Across these recordings, they heard three identical recordings of a motet and three identical recordings of a spiritual with unique applause conditions attached. Listeners’ ratings were influenced by the magnitude of audience applause to a limited degree, but this effect interacted with musical style and presentation order. We observed no differences between the ratings of music and non-music majors, however. Results are interpreted in light of previous research on majority effects, and implications of these results regarding performance evaluation and concert programming are discussed.

The Book Of Songs

Musical performance was a distinctive feature of urban culture in the formative period of Islamic history. At the court of the Abbasid caliphs, and in the residences of the ruling elite, men and women singers performed to predominantly male audiences. The success of a performer was linked to his or her ability to elicit ṭarab, namely a spectrum of emotions and affects, in their audiences. Ṭarab was criticized by religious scholars due, in part, to the controversial performances at court of slave women singers depicted as using music to induce passion in men, diverting them from normative ethical social conduct. This critique, in turn, shaped the ethical boundaries of musical performances and affective responses to them. Abū l-Faraj al-Iṣfahānī’s tenth-century Kitāb al-Aghānī (‘The Book of Songs’) compiles literary biographies of prominent male and female singers from the formative period of Islamic history. It offers rich descriptions of musical performances as well as ensuing manifestations of ṭarab in audiences, revealing at times the polemics with which they were associated. Investigating three biographical narratives from Kitāb al-Aghānī, this paper seeks to answer the following question: How did emotions, gender and status shape on the one hand the musical performances of women singers and on the other their audiences’ emotional responses, holistically referred to as ṭarab. Through this question, this paper seeks to nuance and complicate our understanding of the constraints and opportunities that shaped slave and free women's musical performances, as well as men's performances, at the Abbasid court.

Background: Binocular and accommodative vision problems are common after mild traumatic brain injury (mTBI). Traditionally, the management of visual dysfunctions following mTBI included in-office vision rehabilitation with a trained eye care provider. The concept of providing telehealth for remote vision rehabilitation in mTBI patients is a relatively novel practice that has not been widely utilized until the recent outbreak of the 2019 novel coronavirus (COVID-19) pandemic. Case Report: We describe the implementation of telehealth for remote vision rehabilitation during COVID-19 within the Veterans’ Health Administration (VHA) system in an adult patient with multiple confirmed histories of mTBI. Conclusion: Our telehealth remote vision rehabilitation was successfully implemented utilizing established VHA’s web-based videoconferencing tools. Therapeutic goals identified prior to COVID 19 were addressed without any challenges. The delivery of vision rehabilitation intervention via telehealth allowed for the continuance of services within the home setting that led to improvements in functional vision, decreased perception of performance challenges, and improved quality of life.

Abstract Background Shelter-in-place orders and social distancing guidelines, in response to the COVID-19 pandemic, have limited traditional face-to-face interactions and led to many clinical providers transitioning to the use of videoconferencing platforms. The present study aims to assess how the COVID-19 pandemic has impacted adolescents’/young adults’ (AYA) eating disorder (ED)-related care, and how access to, changes in, perceived disruptions to, and quality of care are associated with ED thoughts and behaviors. Methods AYA enrolled in the RECOVERY study, a pre-existing web-based longitudinal study, and completed a COVID-19-specific survey (n = 89). We examined bivariate associations of four markers of care: i) access to care, ii) changes in care, iii) perceived disruption to care, and iv) quality of care. Using multiple logistic regression, we examined the associations of pandemic-related markers of care with changes in ED thoughts and behaviors. We excluded those not engaged in treatment pre-pandemic (n = 16). Results In the remaining 73 participants, reported access to care was high, with 92% of respondents continuing care with at least one ED provider during the pandemic; however, 47% stopped some treatment during the pandemic. Nearly one-third (32%) perceived a disruption in treatment. Quality of care remained high with 67% reporting care to be better than or as good as pre-pandemic. Respondents acknowledged heightened symptomatology: 81% reported increased ED thoughts and 81% reported increased ED behaviors due to COVID-19-related factors. However, none of the markers of care described were significantly associated with ED thoughts or behaviors in regression analyses adjusting for demographic variables and baseline characteristics, except our quality of care measure which was approaching significance (p = 0.07). Conclusions Our findings show the majority of AYA who had care prior to the pandemic continued receiving some element of their multi-disciplinary ED treatment and perceived their care as high quality. None of the markers of care described were statistically associated with increased ED thoughts and behaviors.

An experimental study was performed on a low-density plasma discharge using two different configurations of the plasma cell cathode, namely, the one mesh system electrodes (OMSE) and the one mesh and three system electrodes (OMTSE), to determine the electrical characteristics of the plasma such as current–voltage characteristics, breakdown voltage (VB), Paschen curves, current density (J), cathode fall thickness (dc), and electron density of the treated sample. The influence of the electrical characteristics of the plasma fluid in the cathode fall region for different cathode configuration cells (OMSE and OMTSE) on the performance quality of a surgical gown was studied to determine surface modification, treatment efficiency, exposure time, wettability property, and mechanical properties. Over a very short exposure time, the treatment efficiency for the surgical gown surface of plasma over the mesh cathode at a distance equivalent to the cathode fall distance dc values of the OMTSE and for OMSE reached a maximum. The wettability property decreased from 90 to 40% for OMTSE over a 180 s exposure time and decreased from 90 to 10% for OMSE over a 160 s exposure time. The mechanisms of each stage of surgical gown treatment by plasma are described. In this study, the mechanical properties of the untreated and treated surgical gown samples such as the tensile strength and elongation percentage, ultimate tensile strength, yield strength, strain hardening, resilience, toughness, and fracture (breaking) point were studied. Plasma had a more positive effect on the mechanical properties of the OMSE reactor than those of the OMTSE reactor.
