Abstract

A VME-based readout system was used for the EUROGRAM gamma-ray detection system. Its primary features include its combination of VMEbus and an environment suitable for housing analog electronics. The readout system reads an event's data form acquisition modules within the VMEbus crate using a single, slightly modified, VMEbus block transfer. This set-up allows dense packing of both analogue signal processing and data acquisition electronics within a unified framework.

60. Developing Tests of Music Performance Improvisation

Author

Brophy, T, McPherson, G, Brophy, T, and McPherson, G

Abstract

This chapter presents a survey of research on the development and validation of a measure to assess instrumentalists’ ability to improvise music. It begins by framing efforts to distinguish between visual, aural, and creative forms of music performance, and the types of assessment tasks required to evaluate music performance improvisation. The chapter surveys a range of related measures that have been used to assess improvisational abilities in young developing musicians and provides a detailed description of the author’s own Test of Ability to Improvise (TAI) that he has used with beginning, intermediate, and advanced level school instrumentalists. Included also are examples of the instrumentalists’ improvisations and a discussion of the implications of the research findings for conceptions of musical development and practical applications within music education.

61. Children's Creativity: A Theoretical Framework and Systematic Review

Author

Kupers, E, Lehmann-Wermser, A, McPherson, G, van Geert, P, Kupers, E, Lehmann-Wermser, A, McPherson, G, and van Geert, P

Abstract

Within education, the importance of creativity is recognized as an essential 21st-century skill. Based on this premise, the first aim of this article is to provide a theoretical integration through the development of a framework based on the principles of complex dynamic systems theory, which describes and explains children’s creativity. This model is used to explain differing views on the role of education in developing children’s creativity. Our second aim is empirical integration. On the basis of a three-dimensional taxonomy, we performed a systematic review of the recent literature (2006–2017, 184 studies) on primary school students’ creativity. Our results show that creativity is most often measured as a static, aggregated construct. In line with our theoretical model, we suggest ways that future research can elaborate on the moment-to-moment interactions that form the basis of long-term creative development, as well as on the mechanisms that connect different levels of creativity.

62. Improvisation, Enaction, and Self-Assessment

Author

Elliott, DJ, Silverman, M, McPherson, G, van der Schyff, D, Elliott, DJ, Silverman, M, McPherson, G, and van der Schyff, D

Abstract

This chapter explores the challenging question of curriculum and assessment for music improvisation pedagogy. It begins by offering a critical review of standard approaches to improvisation pedagogy, arguing that they often neglect the processes of discovery and collaboration that more open or “free” approaches afford. It then discusses the challenges that free improvisation poses to traditional modes of practice and assessment in music education. The chapter considers the argument that improvisation, in its fullest sense, cannot be taught and assessed according to standardized models; it is not something to be inculcated in students, but rather is a fundamental disposition that should be nurtured. This perspective is then developed in light of recent advances in enactive cognitive science, in which living cognition is explored as a fundamentally embodied, embedded, enactive, and extended (4E) phenomenon. The suggestion is made that because the ways living agents engage with these dimensions are not pre-given but rather reflect the adaptive processes associated with survival and well-being in contingent sociomaterial environments, there is a very strong sense in which cognition may be understood as an improvisational process even at the most fundamental levels. Following this, the chapter explores how a 4E cognition model might help guide curriculum development and offer a framework for forms of self-assessment involving collaborative processes of creative action and reflection. In conclusion, the chapter offers a few final thoughts drawn from existing musical communities and the author’s experience as an improvising musician.

64. Applying self-regulated learning microanalysis to study musicians’ practice

Author

McPherson, G, Osborne, M, Evans, P, Miksza, P, McPherson, G, Osborne, M, Evans, P, and Miksza, P

Abstract

This article describes the development of a music practice microanalysis protocol that is based on the three-phase model of self-regulated learning (i.e., Forethought, Performance, and Self-Reflection). Up until now, most studies on music practice have tended to focus on behavioural aspects. The expanded view presented here outlines a technique for mapping the types of behaviours (actions), cognition (thoughts), and affect (feelings) that can help focus musicians’ practice. To explain the technique, we describe the practice of two first year Bachelor of Music students studying at a prominent university music school who are compared at three time points across one semester as they prepare an étude for a performance exam. These case studies demonstrate two broadly contrasting self-regulated learning profiles of how microanalysis can be used to cue students to think about what they are doing and then reflect critically on the strategies they can use to improve their playing. As a technique, microanalysis can inform educational interventions aimed at breaking the cycle of habits that typify musical practice by encouraging musicians to become more behaviourally, metacognitively, and motivationally involved in their own learning.

66. Arts programs in schools : Seven models and a decision-making matrix for school leaders

Author

McFerran, K, Hattie, J, McPherson, G, Crooke, A, Steele, M, McFerran, K, Hattie, J, McPherson, G, Crooke, A, and Steele, M

Abstract

The provision of arts programs in Australian schools is diverse. Studies of music have shown that the quality of music education in private schools is high and well resourced, but in government-funded schools there is greater variation with schools in some states offering little to no embedded programs. Because the arts are not considered core, school leaders have the freedom and responsibility to determine how much, how often, and what kinds of programs should be offered. Without mandated guidelines, our research shows that this is often influenced by leaders' personal experiences of music in their history or family context. School leaders have also described needing to overcome significant barriers in order to justify the provision of programs. Further complicating the picture are the varying views held by school leaders and staff about exactly which benefits arts programs afford. While most agree on the intrinsic value related to artistic skills and creativity more generally, some are less sure about additional benefits such as psychosocial wellbeing benefits or community building, with a diversity of perspectives also reflected in policy documents.

67. Playing an Instrument

Author

McPherson, G, MCPHERSON, G, Davidson, J, Evans, P, McPherson, G, MCPHERSON, G, Davidson, J, and Evans, P

Abstract

Learning to play a musical instrument is one of the most widespread musical activities for children. While much research in the past century has focused on the assessment of musical abilities and the content of their lessons, more recent research has focused on children’s interactions with their social environments and how these interactions impact their ongoing ability and motivation to learn and play music. This chapter explores these social and cognitive developments starting with how children and their parents select an instrument and negotiate the commencement of formal music learning, through to the task related cognitive strategies children use to overcome the difficulties associated with learning and practice, and the ways they may eventually become able to integrate an identity as a musician with their own sense of self. Aspects of self-regulation and self-determination theory are discussed.

Abstract

Objective: To compare standard (native tissue) repair with synthetic mesh inlays or mesh kits.Design: Randomised controlled trial.Setting: Thirty-three UK hospitals.Population: Women having surgery for recurrent prolapse.Methods: Women recruited using remote randomisation.Main Outcome Measures: Prolapse symptoms, condition-specific quality-of-life and serious adverse effects.Results: A Mean Pelvic Organ Prolapse Symptom Score at 1 year was similar for each comparison (standard 6.6 versus mesh inlay 6.1, mean difference [MD] -0.41, 95% CI -2.92 to 2.11: standard 6.6 versus mesh kit 5.9, MD -1.21 , 95% CI -4.13 to 1.72) but the confidence intervals did not exclude a minimally important clinical difference. There was no evidence of difference in any other outcome measure at 1 or 2 years. Serious adverse events, excluding mesh exposure, were similar at 1 year (standard 7/55 [13%] versus mesh inlay 5/52 [10%], risk ratio [RR] 1.05 [0.66-1.68]: standard 3/25 [12%] versus mesh kit 3/46 [7%], RR 0.49 [0.11-2.16]). Cumulative mesh exposure rates over 2 years were 7/52 (13%) in the mesh inlay arm, of whom four women required surgical revision; and 4/46 in the mesh kit arm (9%), of whom two required surgical revision.Conclusions: We did not find evidence of a difference in terms of prolapse symptoms from the use of mesh inlays or mesh kits in women undergoing repeat prolapse surgery. Although the sample size was too small to be conclusive, the results provide a substantive contribution to future meta-analysis.Tweetable Abstract: There is not enough evidence to support use of synthetic mesh inlay or mesh kits for repeat prolapse surgery.

73. The molecular genetic basis of music ability and music-related phenotypes

Author

Hambrick, DZ, Campitelli, G, Macnamara, BN, Tan, YT, McPherson, G, Wilson, SJ, Hambrick, DZ, Campitelli, G, Macnamara, BN, Tan, YT, McPherson, G, and Wilson, SJ

Abstract

In the past decade, researchers have sought to uncover potential genes that underlie various musical traits through molecular genetic approaches once the genetic basis of a musical trait has been established using behavioral genetic methods. Since the 1980s, progress in molecular genetic technology and bioinformatics has brought about the advent of human molecular genetic approaches, especially for elucidating the genetic mechanisms of complex diseases. In contrast, the investigation of the molecular genetic basis of music ability only began to surface in recent years, with Irma Järvelä, a clinical geneticist at the University of Helsinki, Finland, and her collaborators contributing a sizeable and significant research output on this topic. Although this field is still in its infancy, some exciting and converging results are already beginning to emerge.

Abstract

An updated analysis using about 1.5 million events recorded at $\sqrt{s} = M_Z$ with the DELPHI detector in 1994 is presented. Eighteen infrared and collinear safe event shape observables are measured as a function of the polar angle of the thrust axis. The data are compared to theoretical calculations in ${\cal O} (\alpha_s^2)$ including the event orientation. A combined fit of $\alpha_s$ and of the renormalization scale $x_{\mu}$ in $\cal O(\alpha_s^2$) yields an excellent description of the high statistics data. The weighted average from 18 observables including quark mass effects and correlations is $\alpha_s(M_Z^2) = 0.1174 \pm 0.0026$. The final result, derived from the jet cone energy fraction, the observable with the smallest theoretical and experimental uncertainty, is $\alpha_s(M_Z^2) = 0.1180 \pm 0.0006 (exp.) \pm 0.0013 (hadr.) \pm 0.0008 (scale) \pm 0.0007 (mass)$. Further studies include an $\alpha_s$ determination using theoretical predictions in the next-to-leading log approximation (NLLA), matched NLLA and $\cal O(\alpha_s^2$) predictions as well as theoretically motivated optimized scale setting methods. The influence of higher order contributions was also investigated by using the method of Pad\'{e} approximants. Average $\alpha_s$ values derived from the different approaches are in good agreement., Comment: 48 pages

85. Novitates neocaledonicae IV : Three new species of Cryptocarya R.Br. (Lauraceae)

Author

Munzinger, Jérôme and McPherson, G.

Abstract

Three endemic new species of Cryptocarya R.Br. are described from New Caledonia. Cryptocarya adpressa Munzinger & McPherson, sp. nov., is a small-leaved, pinnately veined species resembling species such as C. leptospermoides Kosterm. and C. gracilis Schltr., but differing most notably in its persistent and strongly appressed indument of the inflorescence. Cryptocarya barrabeae Munzinger & McPherson, sp. nov., resembles C. pluricostata but can be distinguished most easily by its elliptical leaf shape and longer, straighter indument. Cryptocarya chrysea Munzinger & McPherson, sp. nov., resembles C. guillauminii Kosterm. in its ovate, densely and persistently pubescent leaves with ascendant lateral veins, but differs most notably in its prominently lenticellate stems and abaxially golden leaves. All three new species are trees occurring in dense humid forest. Two are restricted to non-ultramafic substrate while C. chrysea, sp. nov., occurs on both substrates. They are all known from at least three protected areas, and do not appear to be threatened; thus they are all assigned a preliminarily Least Concern IUCN status.

86. Learning to perform: From 'gifts' and 'talents' to skills and creative engagement

Author

Rink, J, Gaunt, H, Williamson, A, Davidson, J, McPherson, G, Rink, J, Gaunt, H, Williamson, A, Davidson, J, and McPherson, G

Abstract

To perform any skilled activity to expert level requires committed and intensely motivated learning. This chapter explores how musical development, particularly as it applies to learning an instrument, depends crucially on inventive and productive opportunities that coalesce in configurations unique to each learner. It reveals how an obsession with gifts and talents on the parts of researchers, teachers, parents and musicians alike has led to confusion over the nature and acquisition of the skills required for high-level music performance. It traces key theories on family scripts and self-determination to illustrate the ways in which psychological constructs shape belief and thus motivate learning. Environmental catalysts such as practice support and opportunity for creative expression offer additional significant influences. These factors are shown to align with intrapersonal characteristics and are described as syzygies, or inventive configurations, that provide pathways to committed music learning.

87. Motivation, engagement, and performance in elite musical training: A longitudinal study

Abstract

Background Musicians training at the highest levels in university music schools and conservatories face considerable challenges. They need to undertake enormous amounts of practice—an activity which requires substantial effort and can be lonely, difficult, and boring. They also face considerable motivational challenges: studio teachers are renowned for their demandingness, conservatories can be hotbeds of competitiveness and pressure, and the uncertainties and risks of pursuing a music performance career require resilience and adaptability. Little systematic research has examined the motivational dynamics of music training at this level, and the style of studio instruction—a consistent tradition largely unchanged for many centuries—has rarely been scrutinized. Aims We aimed to understand the role motivation plays in cognitive, affective, and behavioral aspects of musicians’ practice, and the subsequent effects that motivation and practice quality have on performance. Method Music students (N=611) from four conservatories and university music schools in three countries participated in the research. A longitudinal survey research design was used, with data collected at four time points over an academic year. Measures were taken from the established literature on motivation in educational settings or developed for the present study, based on theoretical frameworks including self-determination theory and self-regulated learning. Performance examination grades were obtained from the relevant institutions. Hypotheses were tested using structural equation modelling. Results Moderate to large effects were found for the role of motivation in practice quality. Students who were intrinsically motivated were more cognitively, affectively, and behaviorally engaged in their music practice, and had higher self-efficacy for their performance. The extent to which their music learning fulfilled their psychological needs impacted on important outcomes, including performance, career in

Abstract

Background An increasing body of research in both music and sports psychology indicates that repetitive, habitual, and mindless practice often leads to sub-optimal preparation and performance. In contrast, deliberate practice, intrinsic motiva-tion, and a growth mindset can optimise preparation for public performance. Still, the majority of musicians devote their time to blocks of physical practice and mistake-avoidance, as opposed to mental preparation, desirable difficul-ties, and strategies that strengthen self-efficacy and autonomy. Music teachers may want to steer their students away from mindless drill towards 21st century self-regulated learning strategies, yet both the scientific and pedagogical literature is lacking in alternatives supported by empirical research. Aims This exploratory study was designed to capture what musicians planned to practice, as well as what they actually did in the practice room. In order to separate behavior from thought and emotion, we designed a brief questionnaire (seven questions) to accompany a video recording made of a portion of a practice session. Participants were asked to report their intentions regarding practice focus and planning, then to appraise what they had experienced during practice, and, finally, to access the difficulty of applying this strategy and their motivation to use it in the future. Method Fourteen participants, faculty and students in music degree programs at the University of Music and Performing Arts Munich, volunteered for this pilot study to test the effectiveness of the practice questionnaire. Each one completed questions both prior to and following the videotaping of an excerpt of a practice session of their choice. The first three questions (pre-recording) addressed the focus of the practice session, i.e. problem to be solved, the source, and choice of strategy. The last four questions (post-recording) allowed participants to self-rate the effectiveness, new-ness, ease of application, and usefu

Abstract

Background This paper describes the development of a music practice microanalysis protocol that is based on the three phase model of self-regulated learning (i.e., Forethought, Performance and Self-Reflection). Up until now, most studies on music practice have tended to focus on behavioural aspects. The expanded view presented here outlines a technique that focuses on the types of behaviours (actions), cognition (thoughts), and affect (feelings) that can help focus musicians’ practice, and enable them to make improvements to the efficiency of their learning. Aims To develop a research and intervention tool reflecting the breadth of self-regulated learning strategies, and within-subject, moment-to-moment fluctuations in practice quality that determine the intensity and quality of practice within and across practice sessions. Method We conducted a two-stage research study: first, a baseline observational study; second, a practice intervention, involving seven first year Bachelor of Music students studying at a large University music school across two semesters as they prepare repertoire for their performance exams. Results The technique revealed students demonstrate broadly contrasting self-regulated learning profiles. It also informed an effective self-directed educational intervention to cue students to think about what they are doing and then reflect critically on the strategies they can use to improve their playing. Implications This flexible, working microanalytic protocol can inform educational interventions aimed at breaking the cycle of habits that typify musicians at this developmental stage, encouraging them to become more behaviourally, metacognitively, and emotionally involved in their own learning. This tool could be used to help musicians become more aware of their own practice efficiency, and an aid for teachers who wish to adopt the technique to improve their student’s learning.

Abstract

Background: Current interventions for haemorrhoidal disease include traditional haemorrhoidectomy (TH) and\ud stapled haemorrhoidopexy (SH) surgery. However, uncertainty remains as to how they compare from a clinical,\ud quality of life (QoL) and economic perspective. The study is therefore designed to determine whether SH is more\ud effective and more cost-effective, compared with TH.\ud \ud Methods/Design: eTHoS (either Traditional Haemorrhoidectomy or Stapled Haemorrhoidopexy for Haemorrhoidal\ud Disease) is a pragmatic, multicentre, randomised controlled trial. Currently, 29 secondary care centres are open to\ud recruitment. Patients, aged 18 year or older, with circumferential haemorrhoids grade II to IV, are eligible to take part.\ud The primary clinical and economic outcomes are QoL profile (area under the curve derived from the EuroQol Group’s 5\ud Dimension Health Status Questionnaire (EQ-5D) at all assessment points) and incremental cost per quality adjusted life\ud year (QALY) based on the responses to the EQ-5D at 24 months. The secondary outcomes include a comparison of the\ud SF-36 scores, pain and symptoms sub-domains, disease recurrence, complication rates and direct and indirect costs\ud to the National Health Service (NHS). A sample size of n =338 per group has been calculated to provide 90% power\ud to detect a difference in the mean area under the curve (AUC) of 0.25 standard deviations derived from EQ-5D\ud score measurements, with a two-sided significance level of 5%. Allowing for non-response, 400 participants will\ud be randomised per group. Randomisation will utilise a minimisation algorithm that incorporates centre, grade of\ud haemorrhoidal disease, baseline EQ-5D score and gender. Blinding of participants and outcome assessors is not\ud attempted.\ud \ud Discussion: This is one of the largest trials of its kind. In the United Kingdom alone, 29,000 operations for haemorrhoidal\ud disease are done annually. The trial is therefore designed to give robust evidence on which clinicians and health\ud service managers can base management decisions and, more importantly, patients can make informed choices.\ud \ud Trial registration: Current Controlled Trials ISRCTN80061723 (assigned 8 March 2010)

Abstract

Background: \ud Pelvic organ prolapse is common and is strongly associated with childbirth and increasing age. Women with prolapsed are often advised to do pelvic floor muscle exercises, but supporting evidence is limited. Our aim was to establish if one-to-one individualised pelvic floor muscle training (PFMT) is effective in reducing prolapse symptoms. \ud Methods: A parallel‐group multicentre randomised controlled trial (ISRCTN35911035) in female outpatients with newly-diagnosed, symptomatic stage I, II or III prolapse, comparing five PFMT appointments over 16 weeks (n=225) versus a lifestyle advice leaflet (n=222). Treatment allocation was by remote computer allocation using minimisation. Our primary endpoint was participants’ self-report of prolapsed symptoms at 12 months. Group assignment was masked from outcome assessors. We compared outcomes between trial groups in an intention-to-treat analysis. The cost of PFMT and savings on subsequent treatments were calculated to estimate cost-effectiveness.\ud Findings: Compared to the control group, the intervention group reported fewer prolapse symptoms at 12 months (mean difference between groups in change score 1.52, 95% CI [0.46, 2.59], p=0.0053); reported their prolapse to be “better” more often (57.2% versus 44.7%, difference 12.6%, 95% CI [1.1%, 24.1%], p=0.0336); and had an increased but non-significant odds of having less severe stage of prolapse at their 6-month clinical examination, (OR 1.47, 95% CI [0.97, 2.27], p=0.07). The control group had a greater uptake of other prolapse treatment (49.6% versus 24.1%, difference 25.5%, 95% CI [14.5%, 36.0%], p
