The physical and psychological demands of playing a musical instrument are likely to be affected by age-related decline in function, including physical, cognitive, psychological, and organ-related changes. However, the complex neurophysiological demands of playing a musical instrument may delay many normal aging-related changes. This study compared professional classical musicians of different ages, using a range of physical and psychological measures, to discover how increasing age might affect work performance and to identify possible risk and protective factors for physical and psychological health as the musicians age. 377 professional orchestral musicians from eight Australian orchestras (70% response rate), ages 18 to 68 yrs (mean 42.1). Multiple standardized physical and psychological tools were used to evaluate the impact of age on a range of physical and mental health variables. Age was not statistically associated with frequency or severity of performance-related musculoskeletal disorders, ratings of perceived exertion, QuickDASH scores, use of beta-blockers, workplace satisfaction, and most psychological tests. Differences were observed on SPIN (social anxiety) scores, with lowest scores in the oldest age group (10.66 in 55+ yrs vs 17.83 in 18-30 yrs, p=0.016). Older musicians had higher BMIs and fewer practice sessions per day than younger musicians and also were more likely to consume alcohol on 5+ days/wk (44% vs 9%, p=0.003). Advancing age does not appear to exert undue negative impacts on physical and psychological health or performance capacity of professional orchestral musicians. However, dwindling numbers in the older age groups may suggest a "survivor" effect, whereby those who develop significant age-related decrements may cease professional performance at earlier ages. Longitudinal studies on the professional trajectories of professional orchestral musicians are needed to explore this question further.

Professional musicians report a high prevalence of performance-related musculoskeletal disorders (PRMDs). Excessive muscle tension and fatigue have been reported as important factors contributing to PRMDs. To evaluate feasibility and effectiveness of a specific exercise programme delivered via a digital video disc (DVD) targeting PRMDs and associated risk factors. Volunteers from eight Australian symphony orchestras undertook two or more sessions per week over 12 weeks. Questionnaires were administered pre- and post-intervention with items including the frequency and severity of PRMDs, perceived exertion during different playing situations, per formance effects of the DVD and satisfaction rates. Musicians who had also participated in an equivalent face-to-face programme prior to this DVD trial compared the two interventions. One hundred and forty-four out of 576 musicians volunteered (25% uptake), and 50 participants completed a mean 2.1 (SD 0.42) sessions over the 12 week period (41% compliance). PRMD frequency and severity were significantly reduced post-intervention (P benefits of the DVD on strengthening muscles, increasing ease of movement and improving flexibility related to playing. Despite this, perceived exertion levels during private practice, rehearsal and performance remained the same (not significant). Seventy-eight per cent of participants scored their overall experience of the use of the DVD as good or excellent. Owing to its convenience and detailed exercise demonstrations, the DVD was rated as better or much better overall than the face-to-face classes by 55% of participants who had experienced both. An exercise DVD was well received and appeared to be effective, convenient and safe in managing occupational-specific musculoskeletal disorders in musicians.

Full Text Available The Sound Practice Project is a five-year study involving baseline evaluation, development and implementation of musician-specific work health and safety initiatives. A cross-sectional population physical and psychological survey and physical assessment were conducted at the same time, with an auditory health assessment conducted later. The results were used to guide the development of a series of targeted interventions, encompassing physical, psychological and auditory health components. This paper provides an overview of the project but focuses on the health findings arising from the cross-sectional survey.377 musicians from the eight professional symphony orchestras in Australia took part in the cross-sectional study (about 70% of eligible musicians. Eighty-four percent (84% of musicians reported past performance-related musculoskeletal disorder (PRMD episodes; 50% were suffering a current PRMD. Of the 63% who returned hearing surveys, 43% believed they had hearing loss, and 64% used earplugs at least intermittently. Noise exposure was found to be high in private practice, although awareness of risk and earplug use in this environment was lower than in orchestral settings. Improved strategic approaches, acoustic screens and recently developed active earplugs were found to provide effective new options for hearing protection. With respect to psychosocial screening, female musicians reported significantly more trait anxiety, music performance anxiety, social anxiety, and other forms of anxiety and depression than male musicians. The youngest musicians were significantly more anxious compared with the oldest musicians. Thirty-three percent (33% of musicians may meet criteria for a diagnosis of social phobia; 32% returned a positive depression screen and 22% for post-traumatic stress disorder. PRMDs and trigger point discomfort levels were strongly associated with increasing severity of psychological issues such as depression and music

Professional musicians experience high rates of musculoskeletal pain, but only few studies have investigated how this pain is accepted by musicians. To investigate the culture of pain and to explore how professional musicians experience and cope with pain. Ten semi-structured in-depth interviews were conducted; 8 with musicians and 2 with professional elite athletes. In addition, a concert and two rehearsals were observed. The audiotaped interviews were transcribed verbatim. Configurational analysis was used to interpret the material as a whole. Musicians often experience pain as a consequence of prolonged repetitive work early in their career. Such pain is compounded by the lack of breaks during concerts and rehearsals. Orchestras seldom give opportunities for adjustments required for individual instruments, breaks, or action to prevent pain. Musicians' strong sense of coherence and the experience of pain as integral to their identity have encouraged musicians to develop flexible coping strategies. Ignoring pain and potential damage is an accepted concomitant to striving for perfection. A musician does not focus on pain but on the music. For the musician, pain has a significance beyond being something that can simply be removed by a practitioner. Pain tells both an individual story and a cultural story that is crying out to be heard.

The sound in classical orchestral music is louder than noise emissions allowed by national rules in industry. We wanted to assess the audiologic status of professional musicians at different ages of their careers and to look for a coherence of declined hearing ability and the sound emissions in order to substantiate advices for hearing protection and occupational medicine in musicians. Data from questionnaires (anamnestic data on sound exposure in profession and leisure times, use of hearing protection, self-evaluation of hearing function and hearing deficits), audiometric data and amplitudes of OAE were evaluated from 109 professional musicians aged 30-69 years from three major German orchestras and from 110 students of an academy of music (aged 11-19 years). Sound emissions of the whole orchestra and of single instruments/instrument groups were measured at the orchestra stages and pits during rehearsals and performances. None of the musicians was engaged in noisy hobbies and only a few used hearing protectors regularly. More than 50% of the musicians had a hearing loss of 15 dB(A) and more. Highest losses were found among the strings and the brass players. DPOAE amplitudes coincidently declined with the duration of performing music in the orchestras. Professional musicians aged older than 60 years had a significantly greater hearing loss at 4 and 6 kHz than those aged 30-39 years. Among the strings in one orchestra a dominant hearing deficit in the left ears was observed. Musicians need the same health care for their hearing as workers in noisy industry. A better education on the hearing hazards (use of hearing protectors) as well as sound protection in the rehearsal rooms is necessary. Hearing loss in professional musicians should be accepted as an occupational disease.

To determine whether playing a wind or brass musical instrument is associated with reduced snoring or daytime fatigue. Cross-sectional, controlled, anonymous, questionnaire-based observational study. Rehearsal and performance halls. Three hundred and forty musicians from Scotland's five professional orchestras. Snore Outcomes Survey questionnaire and the Epworth Sleepiness Score. Hierarchical linear regression analysis. No significant difference was found between the snoring severity (Snore Outcomes Survey score) or daytime sleepiness (Epworth score) of wind/brass and other professional musicians. A regression model with snoring severity (Snore Outcomes Survey score) as the dependent variable and the three covariates of gender, age and body mass index as independent variables was significant [F(3, 206) = 28.77, P study demonstrated no significant difference between the snoring severity or daytime sleepiness of brass/wind players and other professional orchestral musicians. This result may have been attributed to comparatively low levels of snoring/daytime sleepiness in the population studied. The findings contrast with previous studies examining the effects of singing and didgeridoo playing but concur with a recent similar study of orchestral musicians. A prospective interventional study would be required to determine whether playing a wind or brass instrument improves these variables in patients complaining of disruptive snoring. © 2011 Blackwell Publishing Ltd.

To study visual complaints and eye diseases among professional and amateur orchestral musicians in the Netherlands. In this observational study, members from professional and amateur symphony or wind orchestras were asked to complete a questionnaire collecting demographic data, musical, medical, and family history, and data on present visual complaints and/or eye diseases. Questions about playing in the orchestra were also asked. Data from 70 professionals and 48 amateurs showed that most musicians needed glasses or contact lenses for playing in the orchestra (61% of the professionals, 63% of the amateurs). A majority (66% of professionals, 71% of amateurs) had visited an ophthalmologist at least once during their lifetime, and 10% of the professionals and 23% of the amateurs were currently under treatment of an ophthalmologist. Visual complaints while playing in the orchestra were quite common and included poor lighting conditions, problems with reading small notes, blurred vision, tired eyes, and itching or burning eyes. Professional musicians especially reported adverse effects of eye complaints encountered in the orchestra for daily life; 35% got tired earlier and 33% felt that they could not adequately perform their tasks in the orchestra. The results show that visual complaints and eye problems probably are quite common among orchestral musicians and therefore warrant further interest and research.

The salary and benefits provided by the orchestra presented the lowest score - 6.78 (1.56 points. In general, the musicians showed positive perceptions of the components related to work environment and working conditions. However, remuneration and social relevance are work bases that could contribute to improve the working conditions of these professionals.

Musicians are typically considered to exhibit exceptional auditory skills. Only few studies, however, have substantiated this in basic psychoacoustic tasks. The purpose of the present investigation was to expand our knowledge on basic auditory abilities of musicians compared to non-musicians. Specific goals were: (1) to compare frequency discrimination thresholds (difference limen for frequency [DLF]) of non-musical pure tones in controlled groups of professional musicians and non-musicians; (2) to relate DLF performance to musical background; and (3) to compare DLF thresholds obtained with two threshold estimation procedures: 2- and 3- interval forced choice procedures (2IFC and 3IFC). Subjects were 16 professional musicians and 14 non-musicians. DLFs were obtained for three frequencies (0.25, 1 and 1.5 kHz) using the 3IFC adaptive procedure, and for one frequency (1 kHz) also using the 2IFC. Three threshold estimates were obtained for each frequency, procedure and subject. The results of the present study support five major findings: (a) mean DLFs for musicians were approximately half the values of the non-musicians; (b) significant learning for both groups during the three threshold estimations; (c) classical musicians performed better than those with contemporary musical background; (d) performance was influenced by years of musical experience; and (e) both groups showed better DLF in a 2IFC paradigm compared to the 3IFC. These data highlight the importance of short-term training on an auditory task, auditory memory and factors related to musical background (such as musical genre and years of experience) on auditory performance.

In the present study, we evaluated peripheral and central auditory pathways in professional musicians (with and without hearing loss) compared to non-musicians. The goal was to verify if music exposure could affect auditory pathways as a whole. This is a prospective study that compared the results obtained between three groups (musicians with and without hearing loss and non-musicians). Thirty-two male individuals participated and they were assessed by: Immittance measurements, pure-tone air conduction thresholds at all frequencies from 0.25 to 20 kHz, Transient Evoked Otoacoustic Emissions, Auditory Brainstem Response (ABR), and Cognitive Potential. The musicians showed worse hearing thresholds in both conventional and high frequency audiometry when compared to the non-musicians; the mean amplitude of Transient Evoked Otoacoustic Emissions was smaller in the musicians group, but the mean latencies of Auditory Brainstem Response and Cognitive Potential were diminished in the musicians when compared to the non-musicians. Our findings suggest that the population of musicians is at risk for developing music-induced hearing loss. However, the electrophysiological evaluation showed that latency waves of ABR and P300 were diminished in musicians, which may suggest that the auditory training to which these musicians are exposed acts as a facilitator of the acoustic signal transmission to the cortex.

To compare manual volumetry of gray matter (GM) / white matter (WM) of Broca's area subparts: pars opercularis (POP) and pars triangularis (PTR) in both hemispheres between musicians and nonmusician, as it has been shown that these regions are crucial for musical abilities. A previous voxel-based morphometric (VBM) study conducted in our laboratory reported increased GM density in Broca's area of left hemisphere in male orchestral musicians. Functional segregation of POP/PTR justified separate volumetric analysis of these parts. We used the same cohort for the VBM study. Manual morphometry (stereology) was used to compare volumes between 26/26 right-handed orchestral musicians/nonmusicians. As expected, musicians showed significantly increased GM volume in the Broca's area, specifically in the left POP. No significant results were detected in right POP, left/right PTR GM volumes, and WM volumes for all regions. Results were positively correlated with years of musical performance (r = 0.7, P = 0.0001). This result corroborates the VBM study and is in line with the hypothesis of critical involvement of POP in hearing-action integration being an integral component of frontoparietotemporal mirror neuron network. We hypothesize that increased size of musicians' left POP represent use-dependent structural adaptation in response to intensive audiomotor skill acquisition. Copyright © 2010 Wiley-Liss, Inc.
Full Text Available Interoception is defined as the perceptual activity involved in the processing of internal bodily signals. While the ability of internal perception is considered a relatively stable trait, recent data suggest that learning to integrate multisensory information can modulate it. Making music is a uniquely rich multisensory experience that has shown to alter motor, sensory, and multimodal representations in the brain of musicians. We hypothesize that musical training also heightens interoceptive accuracy comparable to other perceptual modalities. Thirteen professional singers, twelve string players, and thirteen matched non-musicians were examined using a well-established heartbeat discrimination paradigm complemented by self-reported dispositional traits. Results revealed that both groups of musicians displayed higher interoceptive accuracy than non-musicians, whereas no differences were found between singers and string-players. Regression analyses showed that accumulated musical practice explained about 49% variation in heartbeat perception accuracy in singers but not in string-players. Psychometric data yielded a number of psychologically plausible inter-correlations in musicians related to performance anxiety. However, dispositional traits were not a confounding factor on heartbeat discrimination accuracy. Together, these data provide first evidence indicating that professional musicians show enhanced interoceptive accuracy compared to non-musicians. We argue that musical training largely accounted for this effect.

Up to 80% of professional musicians are affected by playing-related musculoskeletal disorders, but data regarding the frequency of craniomandibular dysfunction (CMD) in professional orchestra musicians is scarce. To evaluate the frequency of CMD and its relation to musculoskeletal pain in various body regions. A questionnaire-based survey approach assessing CMD symptoms and musculoskeletal pain in professional orchestra players was adopted. Relative prevalence rates and prevalence ratios for different instrument groups were estimated. A total of 408 musicians completed the questionnaire (response rate 57%). Playing-related pain in the teeth or jaw was reported by 19-47% of musicians and TMJ pain by 15-34%, depending on the instrument group. Current pain in the face indicating a painful CMD was reported in 6-10% and related symptoms such as teeth grinding in 25-34%, jaw clenching in 33-42% and jaw locking in 11-18% of musicians. Females were 2.4 times (95% confidence intervals (CI) 1.49-3.84) more likely to report having had orofacial pain within the last month. Musicians reporting orofacial pain within the last month were 4.8 times (95% CI: 2.83-8.02) more likely to report pain in the neck and 2.5-3.8 times (P neck, shoulder and hands. There is a need to enhance awareness of CMD to optimize early medical diagnosis and treatment.

Left-handed professional musicians percentage is not significantly different from normal population, excepted for piano, organ and harpsichord players. For these instruments the melody is always written for the right hand, probably because of the location of the frequencies which are the most easily perceived by the human ear on the right part of the keyboard. Thus for a lefthanded musician to play piano is comparable to write with his right hand, and as a consequence leads him to play an other instrument for his professional activity.

The primary aim was to determine the level of physiological stress evoked while playing music in a standing position as indicated by heart rate (HR) response. A secondary aim was to analyze the effect of music genre (classic rock, western, contemporary Christian, and metal rock) on the relative HR response. Lastly, we considered potential physiological initiators of the music-playing-induced HR response. HR response was monitored in 27 professional musicians (3 women, 24 men) between the ages of 21 and 67 yrs old during rehearsal and public performances. The percent maximal HR (%MHR) evoked was determined by taking a percentage of the age-predicted maximal HR for each musician and comparing the average %MHR in each genre during public and rehearsal events. The role of the potential initiators of these responses (e.g., number of years playing in public, event type, instrument type, tempo, etc.) was determined using multiple regression analyses. The overall average %MHR responses were 52 ± 5% and 59 ± 5% during rehearsal and public performances, respectively, with genre type having a significant effect on the HR response (p=0.01). Body mass index and tempo were each found to be significant contributors to the HR response while playing music (r²=0.506, p=0.001). Playing music professionally evokes considerable increases in HR response, with music genre influencing the level of the physiological response. We concluded that 50% of the HR response while playing music was associated with body mass index, music tempo, and instrument type.

Typically, Australian orchestral musicians perform on stage, in an orchestra pit, or in a combination of both workplaces. This study explored a range of physical and mental health indicators in musicians who played in these different orchestra types to ascertain whether orchestra environment was a risk factor affecting musician wellbeing. Participants comprised 380 full-time orchestral musicians from the eight major state orchestras in Australia comprised of two dedicated pit orchestras, three stage-only symphonic orchestras, and three mixed stage/pit orchestras. Participants completed a physical assessment and a range of self-report measures assessing performance-related musculoskeletal disorders (PRMD), physical characteristics including strength and perceived exertion, and psychological health, including music performance anxiety (MPA), workplace satisfaction, and bullying. Physical characteristics and performance-related musculoskeletal profiles were similar for most factors on the detailed survey completed by orchestra members. The exceptions were that pit musicians demonstrated greater shoulder and elbow strength, while mixed-workload orchestra musicians had greater flexibility Significantly more exertion was reported by pit musicians when rehearsing and performing. Stage/pit musicians reported less physical exertion when performing in the pit compared with performing on stage. Severity of MPA was significantly greater in pit musicians than mixed orchestra musicians. Pit musicians also reported more frequent bullying and lower job satisfaction compared with stage musicians. There were few differences in the objective physical measures between musicians in the different orchestra types. However, pit musicians appear more psychologically vulnerable and less satisfied with their work than musicians from the other two orchestra types. The physical and psychological characteristics of musicians who perform in different orchestra types have not been adequately

Medicine is a learned profession, but clinical practice is above all a matter of performance, in the best and deepest sense of the word. Because music is, at its core, a pure distillate of real-time performance, musicians are in an excellent position to teach us about better ways to become and remain expert performers in health care and ways for our teachers and mentors to help us do that. Ten features of the professionalization of musicians offer us lessons on how the clinical practice of medicine might be learned, taught, and performed more effectively.

Music performance by professional musicians involves a wide-spectrum of cognitive and multi-sensory motor skills, whose biological basis is unknown. Several neuroscientific studies have demonstrated that the brains of professional musicians and non-musicians differ structurally and functionally and that musical training enhances cognition. However, the molecules and molecular mechanisms involved in music performance remain largely unexplored. Here, we investigated the effect of music performance on the genome-wide peripheral blood transcriptome of professional musicians by analyzing the transcriptional responses after a 2-hr concert performance and after a 'music-free' control session. The up-regulated genes were found to affect dopaminergic neurotransmission, motor behavior, neuronal plasticity, and neurocognitive functions including learning and memory. Particularly, candidate genes such as SNCA, FOS and DUSP1 that are involved in song perception and production in songbirds, were identified, suggesting an evolutionary conservation in biological processes related to sound perception/production. Additionally, modulation of genes related to calcium ion homeostasis, iron ion homeostasis, glutathione metabolism, and several neuropsychiatric and neurodegenerative diseases implied that music performance may affect the biological pathways that are otherwise essential for the proper maintenance of neuronal function and survival. For the first time, this study provides evidence for the candidate genes and molecular mechanisms underlying music performance.

The worlds of a physician and a jazz musician seem entirely different. Various studies, however, relating the concepts behind jazz music to medical practice and education, have been published. The aim of this essayistic review is to summarize previously described concepts behind jazz music and its required artistic skills that could be translated to medicine, encouraging doctors, medical students and medical educators to see their professional environment from a different perspective. A systematic search was conducted using PubMed, Embase, and ERIC databases, combining keywords with regard to jazz, medicine and medical education. Background information concerning jazz music and several jazz musicians was retrieved through an additional nonsystematic search using Google Scholar. Lessons with regard to improvisational skills, both in communication with patients and in a technical context, communication skills, leadership, interprofessional teamwork and coping with errors are presented. Doctors and medical students could learn various lessons from jazz music performance and jazz musicians. The potential and the possibilities of implementing jazz into the medical curriculum, in order to contribute to the development of professional skills and attitudes of medical students, could be explored further.
Identifying attachment ruptures underlying severe music performance anxiety in a professional musician undertaking an assessment and trial therapy of Intensive Short-Term Dynamic Psychotherapy (ISTDP).
Kenny, Dianna T; Arthey, Stephen; Abbass, Allan
Kenny has proposed that severe music performance anxiety that is unresponsive to usual treatments such as cognitive-behaviour therapy may be one manifestation of unresolved attachment ruptures in early life. Intensive Short-Term Dynamic Psychotherapy specifically targets early relationship trauma. Accordingly, a trial of Intensive Short-Term Dynamic Psychotherapy with severely anxious musicians was implemented to assess whether resolution of attachment ruptures resulted in clinically significant relief from music performance anxiety. Volunteer musicians participating in a nationally funded study were screened for MPA severity. Those meeting the critical cut-off score on the Kenny Music Performance Anxiety Inventory were offered a trial of Intensive Short-Term Dynamic Psychotherapy. In this paper, we present the theoretical foundations and rationale for the treatment approach, followed by sections of a verbatim transcript and process analysis of the assessment phase of treatment that comprised a 3-h trial therapy session. The 'case' was a professional orchestral musician (male, aged 55) who had suffered severe music performance anxiety over the course of his entire career, which spanned more than 30 years at the time he presented for treatment following his failure to secure a position at audition. The participant was able to access the pain, rage and grief associated with unresolved attachment ruptures with both parents that demonstrated the likely nexus between early attachment trauma and severe music performance anxiety. Intensive Short-Term Dynamic Psychotherapy is a potentially cost-effective treatment for severe music performance anxiety. Further research using designs with higher levels of evidence are required before clinical recommendations can be made for the use of this therapy with this population.

The organisational culture, behavioural norms, and attitudes of a workplace have a profound influence on levels of injury and illness amongst its workers. While this is well established in Work Health and Safety literature, very little research has attempted to understand the influence of organisational culture on injury risk in the orchestral profession. To address this, the current study aimed to investigate the influence of organisational culture on injury outcomes for orchestral musicians. Using a qualitative case study methodology, in-depth semi-structured interviews were undertaken with 10 professional orchestral cellists (2 freelance and 8 fulltime members) from a single Australian orchestra. After initial data analysis, further interviews were undertaken with a set of 5 orchestral management staff as a means of data triangulation. All data were analysed using a themes-based "analysis of narrative" approach. The findings indicate that an orchestral culture exists in which musicians see injury as a sign of weakness, failure, and poor musicianship. Such negative perceptions of injury influence musicians to play through considerable levels of pain and continue performing with injuries. Because of perceived judgment from the orchestral group, musicians were found to conceal injuries from colleagues and management staff. Freelance musicians felt that disclosing injuries may lead to decreased work opportunities, and both full-time and casual musicians felt that "opening up" about injury may subject them to group judgment about their technique or musicianship. The study suggests education measures which may be effective at influencing individual behaviours and attitudes as well as cultural change initiatives which could lead to long-term positive health outcomes in the orchestral workplace.

Noise-induced hearing loss (NIHL) has been extensively studied in industrial work environments. With the advent of new technologies, loud music has been increasingly affecting listeners outside of the industrial setting. Most research on the effects of music and hearing loss has focused on classical musicians. The purpose of the current study was to examine the relationship between the amount of experience a professional pop/rock/jazz musician has and objective and subjective variables of the musician's hearing loss. This study also examined professional pop/rock/jazz musicians' use of hearing protection devices in relation to the extent of their exposure to amplified music. Forty-four pop/rock/jazz musicians were interviewed using the Pop/Rock/Jazz Musician's Questionnaire (PRJMQ) in order to obtain self-reported symptoms of tinnitus and hyperacusis. Forty-two of the subjects were also tested for air-conduction hearing thresholds in the frequency range of 1-8 kHz. Results show that the extent of professional pop/rock/jazz musicians' exposure to amplified music was related to both objective and subjective variables of hearing loss: Greater musical experience was positively linked to higher hearing thresholds in the frequency range of 3-6 kHz and to the subjective symptom of tinnitus. Weekly hours playing were found to have a greater effect on hearing loss in comparison to years playing. Use of hearing protection was not linked to the extent of exposure to amplified music. It is recommended that further research be conducted with a larger sample, in order to gain a greater understanding of the detrimental effects of hours playing versus years playing.
Full Text Available The feeling of synchrony is fundamental for most social activities and prosocial behaviors. However, little is known about the behavioral correlates of this feeling and its modulation by intergroup differences. We previously showed that the subjective feeling of synchrony in subjects involved in a mirror imitation task was modulated by objective behavioral measures, as well as contextual factors such as task difficulty and duration of the task performance. In the present study, we extended our methodology to investigate possible interindividual differences. We hypothesized that being in a romantic relationship or being a professional musician can modulate both implicit and explicit synchronisation and the feeling of synchrony as well as the ability to detect synchrony from a third person perspective. Contrary to our hypothesis, we did not find significant differences between people in a romantic relationship and control subjects. However, we observed differences between musicians and control subjects. For the implicit synchrony (spontaneous synchronization during walking, the results revealed that musicians that had never met before spontaneously synchronized their movements earlier among themselves than control subjects, but not better than people sharing a romantic relationship. Moreover, in explicit behavioral synchronisation tasks (mirror game, musicians reported earlier feeling of synchrony and had less speed errors than control subjects. This was in interaction with tasks difficulty as these differences appeared only in tasks with intermediate difficulty. Finally, when subjects had to judge synchrony from a third person perspective, musicians had a better performance to identify if they were present or not in the videos. Taken together, our results suggest that being a professional musician can play a role in the feeling of synchrony and its underlying mechanisms.

Full Text Available Background: Poorly functioning work environments may lead to dissatisfaction for the employees and financial loss for the employers. The Job Content Questionnaire (JCQ was designed to measure social and psychological characteristics of work environments. Objective: To investigate the factor construct of the Finnish 14-item version of JCQ when applied to professional orchestra musicians. Methods: In a cross-sectional survey, the questionnaire was sent by mail to 1550 orchestra musicians and students. 630 responses were received. Full data were available for 590 respondents (response rate 38%.The questionnaire also contained questions on demographics, job satisfaction, health status, health behaviors, and intensity of playing music. Confirmatory factor analysis of the 2-factor model of JCQ was conducted. Results: Of the 5 estimates, JCQ items in the “job demand” construct, the “conflicting demands” (question 5 explained most of the total variance in this construct (79% demonstrating almost perfect correlation of 0.63. In the construct of “job control,” “repetitive work” (question 10 demonstrated a perfect correlation index of 0.84 and the items “little decision freedom” (question 14 and “allows own decisions” (question 6 showed substantial correlations of 0.77 and 0.65. Conclusion: The 2-factor model of the Finnish 14-item version of JCQ proposed in this study fitted well into the observed data. The “conflicting demands,” “repetitive work,” “little decision freedom,” and “allows own decisions” items demonstrated the strongest correlations with latent factors suggesting that in a population similar to the studied one, especially these items should be taken into account when observed in the response of a population.

Listening to loud music may be connected to addictive behavior possibly leading to damaging effects on the cochlea. We hypothesized that members of non-professional pop/rock bands with regular exposure to loud music are more likely to show an addictive-like behavior for loud music than matched control subjects. Fifty non-professional musicians and 50 matched control subjects were asked to complete the Northeastern Music Listening Survey (NEMLS) with two basic components. The first comprises an adaptation of the validated Michigan Alcohol Screening Test (MAST) to study the addictive-like behavior towards loud music. The second comprises the criteria outlined by the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) of the American Psychiatric Society for the diagnosis of substance dependence. The NEMLS was scored using the same point system as used in the MAST. The DSM-IV criteria for substance dependence were met by nine of the musician group and by one control subject. Seven of these nine musicians also had a positive NEMLS score. Traits of addictive-like behavior to loud music were detected more often in members of nonprofessional pop/rock bands than in control subjects.

Full Text Available Noise-induced hearing loss (NIHL has been extensively studied in industrial work environments. With the advent of new technologies, loud music has been increasingly affecting listeners outside of the industrial setting. Most research on the effects of music and hearing loss has focused on classical musicians. The purpose of the current study was to examine the relationship between the amount of experience a professional pop/rock/jazz musician has and objective and subjective variables of the musician′s hearing loss. This study also examined professional pop/rock/jazz musicians′ use of hearing protection devices in relation to the extent of their exposure to amplified music. Forty-four pop/rock/jazz musicians were interviewed using the Pop/Rock/Jazz Musician′s Questionnaire (PRJMQ in order to obtain self-reported symptoms of tinnitus and hyperacusis. Forty-two of the subjects were also tested for air-conduction hearing thresholds in the frequency range of 1-8 kHz. Results show that the extent of professional pop/rock/jazz musicians′ exposure to amplified music was related to both objective and subjective variables of hearing loss: Greater musical experience was positively linked to higher hearing thresholds in the frequency range of 3-6 kHz and to the subjective symptom of tinnitus. Weekly hours playing were found to have a greater effect on hearing loss in comparison to years playing. Use of hearing protection was not linked to the extent of exposure to amplified music. It is recommended that further research be conducted with a larger sample, in order to gain a greater understanding of the detrimental effects of hours playing versus years playing.

Most individuals enjoy making music, but pleasure may be diminished by physical complaints. The most common complaints in musicians include injuries of the upper part of the body including the shoulder and spine, skin disorders and hearing problems. Injuries are not so much related to the extent of rehearsing and playing but are mostly the result of a wrong position and misuse of the instrument. Adequate preparation before playing and professional coaching to avoid injuries or to detect problems at an early stage are exceptions rather than the rule. Because of the large number of amateur and professional musicians in the Netherlands, music medicine deserves a more prominent role.

Background Despite the broad popularity of a numeric rating scale (NRS) its psychometric properties are not well known. The objective was to determine if there is any difference in the discrimination ability of the NRS when used for measuring pain severity separately in different body regions. Methods Cross-sectional survey study of 630 professional musicians. Item Response Theory (IRT) was used to define the psychometric properties of the NRS. Results The discrimination ability of the pain NRS was dependent on the body area to which it was applied. The discrimination was low 0.5 (95% CI 0.4. to 0.7) for the hand region and perfect for the shoulder and upper part of the neck– 3.2 (95% CI 1.2 to 5.2) and 10.5 (95% CI 10.0 to 10.9), respectively. Both shoulder and neck NRSs showed a great shift towards higher levels of pain severity meaning that the ability of the NRS to discriminate low levels of pain is poor. NRS scores obtained from all other regions did not demonstrate any discrimination ability. Conclusions The pain NRS might have different psychometric properties depending on the body area to which it is applied. Overall, the modest discrimination ability of the pain NRS implies that it should be used in screening questionnaires with some reservations. PMID:27603011
Full Text Available In the 1980s and 1990s a series of studies investigated musicians’ personalities using Cattell’s 16 personality factors, Eysenck’s PEN super factors, and Costa and McCrae’s Big Five. The findings hinted at some traits most musicians seemed to share, and highlighted differences between the personality traits of brass and string players. However, results were inconclusive and sometimes contradictory. The main aim of this study was to further investigate the topic using novel theoretical frameworks: Peterson and Seligman’s (2004 VIA classification, and Güsewell and Ruch’s (2012 responsiveness to the beautiful and good model. The character strengths and responsiveness to the beautiful and good profiles of classical and non-classical (i.e. jazz, rock, and pop professional musicians, amateur musicians, and non-musicians were compared. In total, 324 participants equally distributed among these three subgroups completed the Values in Action Inventory of Strengths (VIA-IS; Peterson, Park, & Seligman, 2005, the Engagement with Beauty Scale (EBS; Diessner, Solom, Frost, Parsons, & Davidson, 2008, and the Appreciation of Beauty and Excellence Test (ABET; Güsewell & Ruch, 2012. Professional musicians scored significantly higher than non-musicians on self-regulation, appreciation of beauty and excellence, and responsiveness to artistic beauty; they scored significantly lower than amateurs on judgement and perspective, and lower than both amateurs and non-musicians on teamwork, fairness, and leadership. Professional classical musicians scored significantly higher than professional non-classical musicians on prudence. The latter, in turn, displayed significantly higher scores on creativity, bravery, and honesty. The two groups did not differ with respect to any of the responsiveness dimensions.
Professional early childhood educators are often asked for advice about whether or when a young child should learn to play a music instrument.

Current models of speech and language processing postulate the involvement of two parallel processing streams (the dual stream model): a ventral stream involved in mapping sensory and phonological representations onto lexical and conceptual representations and a dorsal stream contributing to sound-to-motor mapping, articulation, and to how verbal information is encoded and manipulated in memory. Based on previous evidence showing that music training has an influence on language processing, cognitive functions, and word learning, we examined EEG-based intracranial functional connectivity in the ventral and dorsal streams while musicians and nonmusicians learned the meaning of novel words through picture-word associations. In accordance with the dual stream model, word learning was generally associated with increased beta functional connectivity in the ventral stream compared to the dorsal stream. In addition, in the linguistically most demanding "semantic task," musicians outperformed nonmusicians, and this behavioral advantage was accompanied by increased left-hemispheric theta connectivity in both streams. Moreover, theta coherence in the left dorsal pathway was positively correlated with the number of years of music training. These results provide evidence for a complex interplay within a network of brain regions involved in semantic processing and verbal memory functions, and suggest that intensive music training can modify its functional architecture leading to advantages in novel word learning. © 2017 Wiley Periodicals, Inc.

Musicians have more robust and efficient neural responses in the cortical and sub-cortical regions, demonstrating that musical experience benefits the processing of both non-linguistic and linguistic stimuli. This study aimed to verify P300's latency and amplitude behavioral using contralateral stimulation in musicians and non-musicians. This was a case-control study. Subjects were divided in two groups: musicians, comprising 30 professional musicians, and non-musicians, comprising 25 subjects without musical experience. The present study showed that the musicians had lower latencies and higher amplitudes than the non-musicians in the P300 without contralateral noise. For the P300 amplitude values, the difference between groups persisted, and the musicians presented significantly higher amplitude values compared with the non-musicians; additionally, the analysis of the noise effect on the P300 response showed that the latency values were significantly increased in the musicians. The central auditory nervous system of musicians presents peculiar characteristics of electrophysiological responses probably due to the plasticity imposed by musical practice.

This thesis considers the dialectical relationship between music and commerce and asks the question why are some musicians uneasy with the commodification of their music? The question is considered from the vantage points of professional musicians and their experiences in dealing with the commodification process. In exploring this dialectic, the thesis is organised around the interactionist orientation and a framework designed by Holt (2004) in which the research design and question emerges f...

Popular (i.e., nonclassical) musicians have higher rates of mental health disorders and mental health service utilization than the general population. Little is known, however, about how popular musicians perceive mental health interventions in terms of overall satisfaction and therapeutic benefit. An online client satisfaction survey was sent to all musicians and family members who received mental health services through a nonprofit mental health organization in Austin, Texas, between July 2014 and June 2015 (n=628). 260 individuals (41.4%) responded to the survey, of whom 94% (n=244) were musicians. A majority of musician respondents were male (60%) and white (82%). 87% received counseling, 32% received psychiatric medication treatment, and 8% received addiction recovery services. 97% of musicians (205/211) rated their counselor as 'very good' or 'excellent,' 88% (64/79) rated their psychiatric providers as 'very good' or 'excellent,' and 94% (17/19) rated their addiction recovery specialists as 'very good' or 'excellent' (nonsignificant between all categories, p>0.05). 89% of musicians receiving counseling, 84% receiving psychiatric medication treatment, and 95% receiving addiction recovery services agreed or strongly agreed that their symptoms and overall functioning improved as a result of their treatment (nonsignificant between all categories, p>0.05). Popular musicians express strong provider satisfaction and overall benefit when mental health interventions are accessible, affordable, and delivered by professionals familiar with their concerns. More research is needed to understand the unique psychosocial stresses popular musicians face to inform treatment planning for this high-risk, underserved population.

International Organizations as Orchestrators reveals how IOs leverage their limited authority and resources to increase their effectiveness, power, and autonomy from states. By 'orchestrating' intermediaries - including NGOs - IOs can shape and steer global governance without engaging in hard, direct regulation. This volume is organized around a theoretical model that emphasizes voluntary collaboration and support. An outstanding group of scholars investigate the significance of orchestration across key issue areas, including trade, finance, environment and labor, and in leading organizations, including the GEF, G20, WTO, EU, Kimberley Process, UNEP and ILO. The empirical studies find that orchestration is pervasive. They broadly confirm the theoretical hypotheses while providing important new insights, especially that states often welcome IO orchestration as achieving governance without creating strong institutions. This volume changes our understanding of the relationships among IOs, nonstate actors and sta...
Full Text Available Introduction Enhanced auditory perception in musicians is likely to result from auditory perceptual learning during several years of training and practice. Many studies have focused on biological processing of auditory stimuli among musicians. However, there is a lack of literature on temporal resolution and active auditory discrimination skills in vocal musicians. Objective The aim of the present study is to assess temporal resolution and active auditory discrimination skill in vocal musicians. Method The study participants included 15 vocal musicians with a minimum professional experience of 5 years of music exposure, within the age range of 20 to 30 years old, as the experimental group, while 15 age-matched non-musicians served as the control group. We used duration discrimination using pure-tones, pulse-train duration discrimination, and gap detection threshold tasks to assess temporal processing skills in both groups. Similarly, we assessed active auditory discrimination skill in both groups using Differential Limen of Frequency (DLF. All tasks were done using MATLab software installed in a personal computer at 40dBSL with maximum likelihood procedure. The collected data were analyzed using SPSS (version 17.0. Result Descriptive statistics showed better threshold for vocal musicians compared with non-musicians for all tasks. Further, independent t-test showed that vocal musicians performed significantly better compared with non-musicians on duration discrimination using pure tone, pulse train duration discrimination, gap detection threshold, and differential limen of frequency. Conclusion The present study showed enhanced temporal resolution ability and better (lower active discrimination threshold in vocal musicians in comparison to non-musicians.

Among artists, musicians may suffer from occupational skin problems; notwithstanding, these conditions have been rarely reviewed. The characteristics of individual performer and the type of instrument will determine the kind of disease. Moreover, the hours that the musician spent to advance artistic skill may influence the severity. The frequency and risk factors of instrument-related skin disorders in musicians from southern Italy were analyzed. An observational study was conducted in 628 musicians. A questionnaire including questions related to age, sex, instrument played, musical activity, previous or current skin disorders, and impact of skin symptoms on music making was submitted. Of 628 musicians, 199 (31.7%) reported suffering from at least 1 skin disease. Cutaneous diseases likely directly correlated with the use of the musical instrument were found in 129 (20.5%) of the 628 subjects. In particular, different patterns of irritant contact dermatitis were found. Skin conditions may be a significant problem in professional instrumentalists. They are mainly related to musical activity. Preventive measures should be established.
Full Text Available Introducción: los músicos son susceptibles de muchas patologías que repercuten en su carrera profesional debido a las posturas forzadas, las horas de práctica, los movimientos repetitivos y la carga psicológica. Las principales causas de los trastornos músculo-esqueléticos son la sobrecarga muscular, la compresión nerviosa y la distonía focal ocupacional. Este grupo de patologías en los músicos no está recogido en el cuadro de enfermedades profesionales español. Objetivo: conocer la producción científica sobre los trastornos músculo-esqueléticos en músicos profesionales como consecuencia de su actividad laboral. Material y Métodos: Se realiza una revisión bibliográfica de la literatura científica publicada entre 2006-2012. Se consultaron las bases de datos MEDLINE, OSH UPDATE, IBECS, Biblioteca Cochrane, Scielo, LILACS y CISDOC. Resultados: se seleccionaron 24 artículos; un estudio experimental, dos revisiones sistemáticas, cuatro estudios de casos y controles, 16 estudios transversales y una serie de casos. Se encontró una prevalencia de 25,5%-86% para los trastornos músculo-esqueléticos, sin consenso para los factores de riesgo. Las principales localizaciones fueron cuello, espalda y brazo. Se encontró más afectación en mujeres, excepto para la distonía focal que fue más frecuente en hombres. Conclusiones: los trastornos músculo-esqueléticos son muy frecuentes en músicos profesionales. Es necesario seguir investigando en esta materia e incidir sobre las medidas de prevención desde las etapas iniciales de su formación. Habría que valorar la inclusión de estos trastornos en los músicos dentro del cuadro de enfermedades profesionales español.Introduction: musicians are susceptible to many disorders that affect their professional careers, due to awkward posture, an excess of practice hours, to repetitive movements and psychological stress.

The creative output of composers, writers, and artists is often influenced by their surroundings. To give a literary example, it has been claimed recently that some of the characters in Oliver Twist and A Christmas Carol were based on real-life people who lived near Charles Dickens in London. Of course, an important part of what we see and hear is not only the people with whom we interact, but also our geophysical surroundings. Of all the geophysical phenomena to influence us, the weather is arguably the most significant, because we are exposed to it directly and daily. The weather was a great source of inspiration for Monet, Constable, and Turner, who are known for their scientifically accurate paintings of the skies. But to what extent does weather inspire composers? The authors of this presentation, who are atmospheric scientists by day but amateur classical musicians by night, have been contemplating this question. We have built a systematic musical database, which has allowed us to catalogue and analyze the frequencies with which weather is depicted in a sample of classical orchestral music. The depictions vary from explicit mimicry using traditional and specialized orchestral instruments, through to subtle suggestions. We have found that composers are generally influenced by their own environment in the type of weather they choose to represent. As befits the national stereotype, British composers seem disproportionately keen to depict the UK's variable weather patterns and stormy coastline.

BACKGROUND: Several studies in the domain of professional musicians describe the relation between playing time and the occurrence of musculoskeletal complaints in professional musicians. To date, no longitudinal cohort study into this relationship has been performed and no amateur musicians were
Research and clinical experience have shown that musicians are at risk of acquiring playing-related injuries. This paper explores findings from a qualitative research study examining the lived experience of professional instrumental musicians with playing-related injuries, which has thus far been missing from the performing arts health literature. This study employed a phenomenological methodology influenced by van Manen to examine the lived experiences of professional musicians with playing-related injuries. Ten professional musicians in Ontario, Canada were interviewed about their experiences as musicians with playing-related injuries. Six of the participants later attended a focus group where preliminary findings were presented. The findings demonstrate a need for education about risk and prevention of injuries that could be satisfied by healthcare professionals and music educators. The practice and training of healthcare professionals should include the "tactful" (van Manen) delivery of care for this important and vulnerable population.

The present study focuses on influences of long-term experience on auditory processing, providing the first evidence for pre-attentively superior auditory processing in musicians. This was revealed by the brain's automatic change-detection response, which is reflected electrically as the mismatch negativity (MMN) and generated by the operation of sensoric (echoic) memory, the earliest cognitive memory system. Major chords and single tones were presented to both professional violinists and non-musicians under ignore and attend conditions. Slightly impure chords, presented among perfect major chords elicited a distinct MMN in professional musicians, but not in non-musicians. This demonstrates that compared to non-musicians, musicians are superior in pre-attentively extracting more information out of musically relevant stimuli. Since effects of long-term experience on pre-attentive auditory processing have so far been reported for language-specific phonemes only, results indicate that sensory memory mechanisms can be modulated by training on a more general level.

Musicians are known to have exceptional sensitivity to sounds, whereas poor phonological representations (or access to these representations) are considered a main characteristic of dyslexic individuals. Though these two characteristics refer to different abilities that are related to non-verbal and verbal skills respectively, the recent literature suggests that they are tightly related. However, there are informal reports of dyslexic musicians. To better understand this enigma, two groups of musicians were recruited, with and without a history of reading difficulties. The pattern of reading difficulties found among musicians was similar to that reported for non-musician dyslexics, though its magnitude was less severe. In contrast to non-musician dyslexics, their performance in pitch and interval discrimination, synchronous tapping and speech perception tasks, did not differ from the performance of their musician peers, and was superior to that of the general population. However, the auditory working memory scores of dyslexic musicians were consistently poor, including memory for rhythm, melody and speech sounds. Moreover, these abilities were inter-correlated, and highly correlated with their reading accuracy. These results point to a discrepancy between their perceptual and working memory skills rather than between sensitivity to speech and non-speech sounds. The results further suggest that in spite of intensive musical training, auditory working memory remains a bottleneck to the reading accuracy of dyslexic musicians. Copyright © 2013 Elsevier Ltd.

Full Text Available Background: Musician's dystonia is a task-specific movement disorder which manifests itself as a loss of voluntary motor control in extensively trained movements. In many cases, the disorder terminates the careers of affected musicians. Approximately 1% of all professional musicians are affected.Etiology and Pathophysiology: The pathophysiology of the disorder is still unclear. Findings include (a reduced inhibition in different levels of the central nervous system, (b maladaptive plasticity, e.g. in the somatosensory cortex and in the basal ganglia, and (c alterations in sensorimotor processing. Epidemiological data demon-strated a higher risk for those musicians who play instruments requiring maximal fine-motorskills. For instruments where workload differs across hands, focal dystonia appears more often in the more intensely used hand. In psychological studies, musicians with dystonia had more perfectionist tendencies than healthy musicians. These findings streng then the assumption that behavioral factors may be involved in the etiology of musician's dystonia. Hereditary factors may play a greater role than previously assumed. Preliminary findings suggest a genetic contributiont o focal task-specific dystonia with phenotypic variations including musician's dystonia.Treatment: Treatment options for musician's dystonia include pharmacological interventions such as administration of Trihexyphenidyl or Botulinum Toxin-A as well as retraining programs and ergonomic changes in the instrument. A long-term follow-up study was performed in 144 patients with musician's dystonia. The outcome was revealed on average 8.4 years after onset of symptoms. Outcome was assessed by patients' subjective rating of cumulative treatmentresponse and response to individual therapies. Seventy-seven patients (54% reported an alleviation of symptoms: 33% of the patients with Trihexyphenidyl, 49% with Botulinum Toxin, 50% with pedagogical retraining, 56% with unmonitored

OBJECTIVES: An investigation of the hearing status of musicians of professional symphony orchestras. Main questions are: (1) Should musicians be treated as a special group with regard to hearing, noise, and noise related hearing problems (2) Do patterns of hearing damage differ for different
Full Text Available Musicians represent a model for examining brain and behavioral plasticity in terms of cognitive and auditory profile, but few studies have investigated whether elderly musicians have better auditory and cognitive abilities than nonmusicians. The aim of the present study was to examine whether being a professional musician attenuates the normal age-related changes in hearing and cognition. Elderly musicians still active in their profession were compared with nonmusicians on auditory performance (absolute threshold, frequency intensity, duration and spectral shape discrimination, gap and sinusoidal amplitude-modulation detection, and on simple (short-term memory and more complex and higher-order (working memory [WM] and visuospatial abilities cognitive tasks. The sample consisted of adults at least 65 years of age. The results showed that older musicians had similar absolute thresholds but better supra-threshold discrimination abilities than nonmusicians in four of the six auditory tasks administered. They also had a better WM performance, and stronger visuospatial abilities than nonmusicians. No differences were found between the two groups' short-term memory. Frequency discrimination and gap detection for the auditory measures, and WM complex span tasks and one of the visuospatial tasks for the cognitive ones proved to be very good classifiers of the musicians. These findings suggest that life-long music training may be associated with enhanced auditory and cognitive performance, including complex cognitive skills, in advanced age. However, whether this music training represents a protective factor or not needs further investigation.

Professional musicians often experience high levels of stress, music performance anxiety (MPA), and performance-related musculoskeletal disorders (PRMDs). Given the fact that most professional musicians begin their musical training before the age of 12, it is important to identify interventions that will address these issues from an early age. This study intended to replicate and expand upon adult research in this area by evaluating the effects of a yoga intervention on MPA and PRMDs in a population of adolescent musicians. The present study was the first to examine these effects. The research team assigned participants, adolescent musicians, into two groups. The intervention group (n = 84) took part in a 6-wk yoga program, and the control group (n = 51) received no treatment. The team evaluated the effects of the yoga intervention by comparing the scores of the intervention group to those of the control group on a number of questionnaires related to MPA and PRMDs. The study was conducted at the Boston University Tanglewood Institute (BUTI). BUTI is a training academy for advanced adolescent musicians, located in Lenox, Massachusetts. Participants were adolescent, residential music students (mean age = 16 y) in a 6-wk summer program at the BUTI in 2007 and 2008. Participants in the yoga intervention group were requested to attend three, 60-min, Kripalustyle yoga classes each wk for 6 wk. MPA was measured using the Performance Anxiety Questionnaire (PAQ) and the Music Performance Anxiety Inventory for Adolescents (MPAI-A). PRMDs were measured using the Performance-Related Musculoskeletal Disorders Questionnaire (PRMD-Q). RESULTS • Yoga participants showed statistically significant reductions in MPA from baseline to the end of the program compared to the control group, as measured by several subscales of the PAQ and MPAI-A; however, the results for PRMDs were inconsistent. The findings suggest that yoga may be a promising way for adolescents to reduce MPA and
In the neuroscience of music, musicians have traditionally been treated as a unified group, as if the demands set by their musical activities would be more or less equal in terms of perceptual, cognitive, and motor functions. However, obviously, their musical preferences differentiate them to a higher degree, for instance, in terms of the instrument they choose and the music genre they are mostly engaged with as well as their practicing style. This diversity in musicians' profiles has been recently taken into account in several empirical endeavors. The present contribution will review the evidence available about the various neurocognitive profiles these different kinds of musicians display.
This paper will explore types of learning, which takes place when musicians work in situations where they have to connect to community contexts. It will first address musicians’ changing professional roles in the changing sociocultural landscape and the need for lifelong learning and emergence of

Many investigations have reported structural, functional, and cognitive changes in the brains of musicians, which occur as a result of many years of musical practice. We aimed to investigate if intensive, long-term musical practice is associated with improved visual memory ability. Musicians and non-musicians, who were comparable in age, gender, and education, were submitted to a visual memory test. The test consisted of the presentation of four sets of stimuli, each one containing eight figures to be memorized. Each set was followed by individual figures and the subject was required to indicate if each figure was or was not present in the memorized set, by pressing the corresponding keys. We divided the test in two parts, in which the stimuli had greater or reduced semantic coding. Overall, musicians showed better performance on reaction times, but not on accuracy. An additional analysis revealed no significant interaction between group and any part of the test in the prediction of the outcomes. When simple reaction time was included as covariate, no significant difference between groups was found on reaction times. In the group of musicians, we found some significant correlations between variables related to musical practice and performance in the visual memory test. In summary, our data provide no evidence of enhanced visual memory ability in musicians, since there was no difference in accuracy between groups. Our results suggest that performance of musicians in the visual memory test may be associated with better sensorimotor integration, since although they have presented shorter reaction times, such effect disappeared when taken in consideration the simple reaction time test. However, given existing evidence of associations between simple reaction time and cognitive function, their performance in the visual memory test could also be related to enhanced visual attention ability, as has been suggested by previous studies, but this hypothesis deserves more

Full Text Available Task-specific focal dystonia is a movement disorder that is characterized by the loss of voluntary motor control in extensively trained movements. Musician's dystonia is a type of task-specific dystonia that is elicited in professional musicians during instrumental playing. The disorder has been associated with deficits in timing. In order to test the hypothesis that basic timing abilities are affected by musician's dystonia, we investigated a group of patients (N = 15 and a matched control group (N = 15 on a battery of sensory and sensorimotor synchronization tasks. Results did not show any deficits in auditory-motor processing for patients relative to controls. Both groups benefited from a pacing sequence that adapted to their timing (in a sensorimotor synchronization task at a stable tempo. In a purely perceptual task, both groups were able to detect a misaligned metronome when it was late rather than early relative to a musical beat. Overall, the results suggest that basic timing abilities stay intact in patients with musician's dystonia. This supports the idea that musician's dystonia is a highly task-specific movement disorder in which patients are mostly impaired in tasks closely related to the demands of actually playing their instrument.

Recreational music exposure is a potential risk factor for noise-induced hearing loss (NIHL). Augmented hearing protectors have been designed with modified attenuation characteristics to combine hearing protection and listening comfort. However, to date, only a few independent studies have assessed the performance of those augmented protectors in realistic exposure conditions. This study compares the listening experience and temporary effects on cochlear status with different types of earplugs after exposure to contemporary club music. Five different types of commercially available hearing protectors were worn, all commonly used during leisure-time music exposure. Four of them were augmented premolded earplugs and the fifth type was an inexpensive, standard earplug frequently distributed for free at music events. During five different test sessions of 30 min each, participants not professionally involved in music wore one particular type of protector. Contemporary club music was played at sound pressure levels (SPLs) representative of concerts and bars. After each listening session, a questionnaire on sound quality and general appreciation was completed. In addition, otoacoustic emissions (OAEs) were measured directly before and after music exposure. The reported appreciation clearly differed depending on the addressed characteristics and the specific earplug type. In this test group, the reported appreciation mainly depended on comfort and looks, while differences in sound quality were less noticeable. The changes in OAE amplitude before and after noise exposure were small in terms of clinical standards. Nevertheless, the observed temporary shifts differed systematically for the different types of hearing protectors, with two types of musician earplug showing a more systematic decline than the others. Further research with respect to actual use and achieved protection for real, unsupervised music exposure is warranted.

Professional musicians are oftentimes exposed to high levels of sound. Prolonged or severe exposure to high sound levels could lead to permanent hearing loss and compromise their career. The logical solution would be to wear hearing protection devices (HPDs) when appropriate. However, perceptual discomfort associated with wearing HPD can discourage their use by musicians. The perceptual discomfort is caused by two detrimental effects: the occlusion effect and the isolation effect. The occlusion effect is often reported as an augmented, unnatural and annoying perception of one's own voice or instrument mechanically coupled to the head when wearing HPDs. The isolation effect is the unnatural sensation of being isolated from a given sound environment and can be caused by wearing HPDs that do not compensate for psychoacoustical factors and therefore alter the wearer's auditory perception. Both effects are highly unfavorable to the musicians' auditory perception and compromise their capacity to perform to the best of their abilities for their audience. They are among the reasons most often reported by musicians to decide not to wear HPDs. This master's project presents the concept and first prototype of an active HPD for musicians that aims at solving the detrimental effects while protecting the musician's hearing. A solution for the occlusion effect is presented in the form of an earplug complemented with in-ear active noise control. Practical design issues and required trade-off are analyzed through a literature review and the implementation and characterization of an active occlusion effect reduction system, allowing reduction of the occlusion effect between 8.5 and 12 dB at 250 Hz. A solution for the isolation effect is presented in the form of an earplug complemented with digital signal processing capabilities. Factors that may cause the isolation effect are identified through a literature review and corresponding algorithms that aim at re-establishing the

The present study investigated musical imagery in musicians and nonmusicians by means of magnetoencephalography (MEG). We used a new paradigm in which subjects had to continue familiar melodies in their mind and then judged if a further presented tone was a correct continuation of the melody. Incorrect tones elicited an imagery mismatch negativity (iMMN) in musicians but not in nonmusicians. This finding suggests that the MMN component can be based on an imagined instead of a sensory memory trace and that imagery of music is modulated by musical expertise.

Dystonias are defined as a joint sustained and involuntary contraction of agonist and antagonist muscles, which can cause torsion, repetitive abnormal involuntary movements, and/or abnormal postures. One special group of dystonias are those known as occupational, which include dystonia disorders triggered by a repetitive motor activity associated with a specific professional activity or task. Musicians are a population particularly vulnerable to these types of dystonia, which are presented as a loss of coordination and voluntary motor control movements highly trained in musical interpretation. Our aim is to describe a clinical series of focal dystonias in musicians evaluated and treated in our centre. Data is presented on a clinical series of 12 musicians with occupational dystonia. Their history and phenomenology are described, as well as well as their outcome after therapy. Demographic details: Mean age 34.8 ± 11.8 years, 10 males (83.3%) and 2 females (16.7%). History of trauma in dystonic segment, 6 patients (50%); family history of neurological diseases in first-degree relatives, 6 patients (50%); occupational history according to music category, 8 patients (66.6%) were classical musicians and 4 patients (33.3%) were popular musicians. The dystonia syndrome was characterised by having a mean age of onset of 28.2 ± 11.3 years (range 18-57 years). The segment affected was the hand (91.7%) in 11 patients. Of all the musicians seen in the clinic, 9 of them (75%) received therapy. The majority of patients appeared to have triggering factors specific to musical execution and linked to the requirement of fine motor control. It should be mentioned that 50% of the musicians treated maintained their professional activity or position in the orchestra to which they belonged. The majority of our phenomenological findings are consistent with those reported in the current literature. However, it is worth mentioning the presence of triggering factors attributed to the
Full Text Available Numerous studies have demonstrated that the structural and functional differences between professional musicians and non-musicians are not only found within a single modality, but also with regard to multisensory integration. In this study we have combined psychophysical with neurophysiological measurements investigating the processing of non-musical, synchronous or various levels of asynchronous audiovisual events. We hypothesize that long-term multisensory experience alters temporal audiovisual processing already at a non-musical stage. Behaviorally, musicians scored significantly better than non-musicians in judging whether the auditory and visual stimuli were synchronous or asynchronous. At the neural level, the statistical analysis for the audiovisual asynchronous response revealed three clusters of activations including the ACC and the SFG and two bilaterally located activations in IFG and STG in both groups. Musicians, in comparison to the non-musicians, responded to synchronous audiovisual events with enhanced neuronal activity in a broad left posterior temporal region that covers the STG, the insula and the Postcentral Gyrus. Musicians also showed significantly greater activation in the left Cerebellum, when confronted with an audiovisual asynchrony. Taken together, our MEG results form a strong indication that long-term musical training alters the basic audiovisual temporal processing already in an early stage (direct after the auditory N1 wave, while the psychophysical results indicate that musical training may also provide behavioral benefits in the accuracy of the estimates regarding the timing of audiovisual events.

In the act of music listening, many people break down musical pieces into chunks such as verses and choruses. Recent work on music segmentation has shown that highly agreed segment boundaries are also considered strong and are described by using multiple cues. However, these studies could...... not pinpoint the effects of data collection methods and of musicianship on boundary perception. Our study investigated the differences between segmentation tasks performed by musicians in real-time and non real-time listening contexts. Further, we assessed the effect of musical training on the perception...... at a time-scale of 10 seconds after comparing segmentation data at different resolutions. Further, musicians located significantly more boundaries in the non real-time task than in the real-time task for 5 out of 6 examples. We found a clear effect of the task but no effects of musical training upon...

Our focus in this study was the assessment of transient evoked otoacoustic emissions (TEOAEs) in a large group of rock musicians. A further objective was to analyse tinnitus among rock musicians as related to TEOAEs. The study was a cross-sectional survey of rock musicians selected at random. A control group was included at random for comparison. We recruited 111 musicians and a control group of 40 non-musicians. Testing was conducted by using clinical examination, pure tone audiometry, TEOAEs and a questionnaire. TEOAE SNR in the half-octave frequency band centred on 4 kHz was significantly lower bilaterally in musicians than controls. This effect was strongly predicted by age and pure-tone hearing threshold levels in the 3-6 kHz range. Bilateral hearing thresholds were significantly higher at 6 kHz in musicians. Twenty percent of the musicians had permanent tinnitus. There was no association between the TEOAE parameters and permanent tinnitus. Our results suggest an incipient hearing loss at 6 kHz in rock musicians. Loss of TEOAE SNR in the 4 kHz half-octave frequency band was observed, but it was related to higher mean 3-6 kHz hearing thresholds and age. A large proportion of rock musicians have permanent tinnitus.

Stress velopharyngeal insufficiency (SVPI) is an uncommon but often career-threatening condition affecting professional brass and woodwind musicians. To review the evaluation of and treatment for SVPI in professional musicians with lipoinjection to the posterior pharyngeal wall. A retrospective medical record and literature review. Two professional musicians with SVPI treated with autologous lipoinjection to the posterior pharyngeal wall were included. Nasopharyngoscopy was performed while patients played their instrument both before and after injection. To assess the effectiveness of autologous fat injection to the posterior pharyngeal wall to treat stress velopharyngeal insufficiency in 2 professional instrumentalists. Successful treatment was the absence of VPI during playing as visualized by flexible nasopharyngoscopy. After autologous lipoinjection of the posterior pharyngeal wall, 1 patient resumed full play with complete resolution, now 3 years after lipoinjection pharyngoplasty. The other patient received temporary resolution. Both had no surgical complications. Stress VPI is often a career-threatening condition for professional brass and woodwind musicians, with a cited incidence of 34%. Various treatment options in the literature include observation, speech and language pathology referral for pharyngeal strengthening, lipoinjection of the soft palate, and more invasive options, such as sphincter pharyngoplasty, pharyngeal flaps and V-Y pushback. Autologous fat injection pharyngoplasty of the posterior pharyngeal wall may be a less invasive treatment option for musicians with SVPI.

Full Text Available Tourette's syndrome (TS is defined as a disorder characterized by multiple motor tics and at least one vocal tic that have lasted for not less than one year. It is a relatively complex neurobehavioral disorder, in which patients may present with coexistent attention deficit hyperactivity disorder, obsessive-compulsive disorder or other behavioral comorbidities. The musical genius Wolfgang Amadeus Mozart (1756-1791 and the rock star Kurt Cobain (1967-1994 may both have suffered from TS, and some contemporary musicians have had their clinical condition confirmed as TS. Our hypothetical diagnosis of TS in Mozart and Cobain is based on the presence of tics and psychiatric comorbidities. In contemporary musicians, such as Michael Wolff, Nick Van Bloss and James Durbin, TS has often only been diagnosed after a considerable delay. This delay in diagnosis and the controversies surrounding the clinical case of Mozart show how difficult a confirmatory diagnosis of this complex disease is.

We compared neuropsychological test scores among older adult non-musicians, low-activity musicians (memory. The current study supports late life cognitive benefits of early musical training, but only in select cognitive domains, including language, executive functioning, and visual spatial ability. The results are discussed in the context of cognitive reserve and aging.

Music and speech are two of the most relevant and common sounds in the human environment. Perceiving and processing these two complex acoustical signals rely on a hierarchical functional network distributed throughout several brain regions within and beyond the auditory cortices. Given their similarities, the neural bases for processing these two complex sounds overlap to a certain degree, but particular brain regions may show selectivity for one or the other acoustic category, which we aimed to identify. We examined 53 subjects (28 of them professional musicians) by functional magnetic resonance imaging (fMRI), using a paradigm designed to identify regions showing increased activity in response to different types of musical stimuli, compared to different types of complex sounds, such as speech and non-linguistic vocalizations. We found a region in the anterior portion of the superior temporal gyrus (aSTG) (planum polare) that showed preferential activity in response to musical stimuli and was present in all our subjects, regardless of musical training, and invariant across different musical instruments (violin, piano or synthetic piano). Our data show that this cortical region is preferentially involved in processing musical, as compared to other complex sounds, suggesting a functional role as a second-order relay, possibly integrating acoustic characteristics intrinsic to music (e.g., melody extraction). Moreover, we assessed whether musical experience modulates the response of cortical regions involved in music processing and found evidence of functional differences between musicians and non-musicians during music listening. In particular, bilateral activation of the planum polare was more prevalent, but not exclusive, in musicians than non-musicians, and activation of the right posterior portion of the superior temporal gyrus (planum temporale) differed between groups. Our results provide evidence of functional specialization for music processing in specific
Full Text Available The corpus callosum (CC is a brain structure composed of axon fibres linking the right and left hemispheres. Musical training is associated with larger midsagittal cross-sectional area of the CC, suggesting that interhemispheric communication may be faster in musicians. Here we compared interhemispheric transmission times (ITTs for musicians and non-musicians. ITT was measured by comparing simple reaction times to stimuli presented to the same hemisphere that controlled a button-press response (uncrossed reaction time, or to the contralateral hemisphere (crossed reaction time. Both visual and auditory stimuli were tested. We predicted that the crossed-uncrossed difference (CUD for musicians would be smaller than for non-musicians as a result of faster interhemispheric transfer times. We did not expect a difference in CUDs between the visual and auditory modalities for either musicians or non-musicians, as previous work indicates that interhemispheric transfer may happen through the genu of the CC, which contains motor fibres rather than sensory fibres. There were no significant differences in CUDs between musicians and non-musicians. However, auditory CUDs were significantly smaller than visual CUDs. Although this auditory-visual difference was larger in musicians than non-musicians, the interaction between modality and musical training was not significant. Therefore, although musical training does not significantly affect ITT, the crossing of auditory information between hemispheres appears to be faster than visual information, perhaps because subcortical pathways play a greater role for auditory interhemispheric transfer.

In this paper we introduce Musician Map, a web-based interactive tool for visualizing relationships among popular musicians who have released recordings since 1950. Musician Map accepts search terms from the user, and in turn uses these terms to retrieve data from MusicBrainz.org and AudioScrobbler.net, and visualizes the results. Musician Map visualizes relationships of various kinds between music groups and individual musicians, such as band membership, musical collaborations, and linkage to other artists that are generally regarded as being similar in musical style. These relationships are plotted between artists using a new timeline-based visualization where a node in a traditional node-link diagram has been transformed into a Timeline-Node, which allows the visualization of an evolving entity over time, such as the membership in a band. This allows the user to pursue social trend queries such as "Do Hip-Hop artists collaborate differently than Rock artists".

Performance anxiety in musicians may be severe enough to require intervention but has been the subject of relatively little clinical research. The authors' objectives were to describe the results of a comprehensive clinical and laboratory assessment and to perform a double-blind, placebo-controlled study comparing buspirone, cognitive-behavior therapy, and the combination of these treatments for performance anxiety. Ninety-four subjects were recruited by mass media announcements and were seen in a university-based outpatient psychiatric clinic. Assessments were 1) questionnaires for all 94 subjects, 2) diagnostic interview of 50 subjects, and 3) laboratory performance of 34 subjects. Treatment conditions were 1) 6 weeks of buspirone, 2) 6 weeks of placebo, 3) a five-session, group cognitive-behavior therapy program with buspirone, or 4) the cognitive-behavior therapy program with placebo. Treatment outcome measures included subjective anxiety ratings and heart rate measures during a laboratory performance, a questionnaire measure of performance confidence, and a blind rating of musical performance quality. All subjects fulfilled criteria for DSM-III-R social phobia. Of the 15 full-time professional musicians, ten had tried propranolol and three had stopped performing. Most of the subjects had substantial anxiety and heart rate increases during laboratory speech and musical performances. Cognitive-behavior therapy resulted in statistically significant reductions in subjective anxiety, improved quality of musical performance, and improved performance confidence. Buspirone was not an effective treatment. Cognitive-behavior therapy is a viable treatment approach for performance anxiety in musicians.
Full Text Available The ability to remember tempo (the perceived frequency of musical pulse without external references may be defined, by analogy with the notion of absolute pitch, as absolute tempo (AT. Anecdotal reports and sparse empirical evidence suggest that at least some individuals possess AT. However, to our knowledge, no systematic assessments of AT have been performed using laboratory tasks comparable to those assessing absolute pitch. In the present study, we operationalize AT as the ability to identify and reproduce tempo in the absence of rhythmic or melodic frames of reference and assess these abilities in musically trained and untrained participants. We asked 15 musicians and 15 non-musicians to listen to a seven-step `tempo scale' of metronome beats, each associated to a numerical label, and then to perform two memory tasks. In the first task, participants heard one of the tempi and attempted to report the correct label (identification task, in the second, they saw one label and attempted to tap the correct tempo (production task. A musical and visual excerpt was presented between successive trials as a distractor to prevent participants from using previous tempi as anchors. Thus, participants needed to encode tempo information with the corresponding label, store the information, and recall it to give the response. We found that more than half were able to perform above chance in at least one of the tasks, and that musical training differentiated between participants in identification, but not in production. These results suggest that AT is relatively wide-spread, relatively independent of musical training in tempo production, but further refined by training in tempo identification. We propose that at least in production, the underlying motor representations are related to tactus, a basic internal rhythmic period that may provide a body-based reference for encoding tempo.

Musicians typically show enhanced pitch-discrimination ability compared to non-musicians, consistent with the fact that musicians are more sensitive to some acoustic features critical for both speech and music processing. However, it is still unclear which mechanisms underlie this perceptual...... enhancement. In a previous behavioral study, musicians showed an increased pitch-discrimination performance for both resolved and unresolved complex tones suggesting an enhanced neural representation of pitch at central stages of the auditory system. The aim of this study was to clarify whether musicians show...... (i) differential neural activation in response to complex tones as compared to non-musicians and/or (ii) finer fundamental frequency (F0) representation in the auditory cortex. Assuming that the right auditory cortex is specialized in processing fine spectral changes, we hypothesized that an enhanced...

Many people are inclined to believe that popular music artists are prone to die prematurely. Scientific research into this matter is scarce. There is only one epidemiological study on this subject, showing that mortality among pop stars during the first 25 years after they became famous is increased. This mortality is higher in Northern America than it is in Europe, but European pop stars die on average at an earlier age. A fairly common belief states that many pop stars die at the age of 27 years. This age has even been proclaimed as the most critical for modern musicians. However, data of several hundred deceased pop stars shows no evidence for increased mortality at the age of 27. Moreover, the data suggests that the age of death has increased over the past forty years. As far as the cause of death is concerned, overdose of drugs or alcohol rank highly next to cardiovascular disease and malignancy.
Classical music is distinguished among professions in several ways: work has to start in childhood in order to achieve proficiency; the training takes an average of 16 years in order to become a professional musician (Manturzewska, 1990); the cost of training is high; a high level of discipline is required to develop performance abilities…
Despite an increase in participation at all levels of the music profession, women continue to experience fewer opportunities to forge careers in music and are less likely than men to apply for leadership positions. This article presents results from a study in which 152 instrumental musicians reflected upon their professional practice and career…

In spite of many years’ efforts, it is difficult to prove substantial improvements of the work environment and policymakers are continuously searching for new efficient strategies. This paper examines the concept of orchestration of work environment programs, based on an empirical analysis...... of recent Danish policy. Orchestration is a strategy where different stakeholders and activities are integrated into a unified program aimed at a specific target group. The analysis includes three policy cases, supplemented with two company case studies. The research shows a move toward a more governance...... type of regulation, which is not only emerging in network but also includes more explicitly orchestrated policy programs. The stakeholders participate in the network with different interests and the orchestration of work environment policies is therefore built on a platform of regulation...

Music performance anxiety (MPA) can be defined as a lasting and intense apprehension connected with musical performance in public. Studies suggest that MPA can be regarded as a subtype of social anxiety. Since individuals with social anxiety have deficits in the recognition of facial emotion, we hypothesized that musicians with high levels of MPA would share similar impairments. The aim of this study was to compare parameters of facial emotion recognition (FER) between musicians with high and low MPA. 150 amateur and professional musicians with different musical backgrounds were assessed in respect to their level of MPA and completed a dynamic FER task. The outcomes investigated were accuracy, response time, emotional intensity, and response bias. Musicians with high MPA were less accurate in the recognition of happiness ( p = 0.04; d = 0.34), had increased response bias toward fear ( p = 0.03), and increased response time to facial emotions as a whole ( p = 0.02; d = 0.39). Musicians with high MPA displayed FER deficits that were independent of general anxiety levels and possibly of general cognitive capacity. These deficits may favor the maintenance and exacerbation of experiences of anxiety during public performance, since cues of approval, satisfaction, and encouragement are not adequately recognized.

The ability to discriminate phonemes varying in spectral and temporal attributes constitutes one of the most basic intrinsic elements underlying language learning mechanisms. Since previous work has consistently shown that professional musicians are characterized by perceptual and cognitive advantages in a variety of language-related tasks, and since vowels can be considered musical sounds within the domain of speech, here we investigated the behavioral and electrophysiological correlates of native vowel discrimination learning in a sample of professional musicians and non-musicians. We evaluated the contribution of both the neurophysiological underpinnings of perceptual (i.e., N1/P2 complex) and mnemonic functions (i.e., N400 and P600 responses) while the participants were instructed to judge whether pairs of native consonant-vowel (CV) syllables manipulated in the first formant transition of the vowel (i.e., from /tu/ to /to/) were identical or not. Results clearly demonstrated faster learning in musicians, compared to non-musicians, as reflected by shorter reaction times and higher accuracy. Most notably, in terms of morphology, time course, and voltage strength, this steeper learning curve was accompanied by distinctive N400 and P600 manifestations between the two groups. In contrast, we did not reveal any group differences during the early stages of auditory processing (i.e., N1/P2 complex), suggesting that faster learning was mediated by an optimization of mnemonic but not perceptual functions. Based on a clear taxonomy of the mnemonic functions involved in the task, results are interpreted as pointing to a relationship between faster learning mechanisms in musicians and an optimization of echoic (i.e., N400 component) and working memory (i.e., P600 component) functions.

Full Text Available Modern cochlear implant (CI users understand speech but find difficulty in music appreciation due to poor pitch perception. Still, some deaf musicians continue to perform with their CI. Here we show unexpected results that CI musicians can reliably tune a guitar by CI alone and, under controlled conditions, match simultaneously presented tones to <0.5 Hz. One subject had normal contralateral hearing and produced more accurate tuning with CI than his normal ear. To understand these counterintuitive findings, we presented tones sequentially and found that tuning error was larger at ∼ 30 Hz for both subjects. A third subject, a non-musician CI user with normal contralateral hearing, showed similar trends in performance between CI and normal hearing ears but with less precision. This difference, along with electric analysis, showed that accurate tuning was achieved by listening to beats rather than discriminating pitch, effectively turning a spectral task into a temporal discrimination task.

The purpose of this study was to evaluate the hearing and subjective auditory symptoms in a group of nonprofessional pop/rock musicians who had experienced repeated exposures to intense sound levels during at least 5 yr of musical activity. An evaluation of both ears in 42 nonprofessional pop/rock musicians included pure-tone audiometry in the conventional and extended high-frequency range, the measurement of uncomfortable loudness levels, and an assessment of tinnitus and hypersensitivity to sound. Exclusion criteria were (a) the occurrence of acoustic trauma, (b) excessive noise exposure during occupational activities, (c) a history of recurrent otitis media, (d) previous ear surgery, (e) a fracture of the cranium, (f) ingestion of potentially ototoxic drugs, and (g) reported hearing difficulties within the immediate family. These audiometric results were then compared with a control group of 20 otologically normal young adults with no history of long-term noise exposure. After adjusting for age and gender, relative to ISO 7029, the mean hearing threshold in the frequency range of 3 to 8 kHz was 6 dB in the musicians and 1.5 dB in the control group. This difference was statistically significant (Mann-Whitney rank sum test, p rock musicians who had experienced repeated exposure to intense sound levels over at least 5 yr but with minimal impact on their lives. Moreover, hearing loss was minimal in the subjects who always used ear protection, being only 0.9 dB higher than the control group. In contrast, hearing loss was significantly more pronounced, at 6.7 dB higher than the control group, in those musicians who never used ear protection. Continued education about the risk to hearing and the benefits of the persistent use of ear protection is warranted for musicians who are exposed frequently to intense sound levels.
Full Text Available Secure orchestration is an important concern in the internet of service. Next to providing the required functionality the composite services must also provide a reasonable level of security in order to protect sensitive data. Thus, the orchestrator has a need to check whether the complex service is able to satisfy certain properties. Some properties are expressed with metrics for precise definition of requirements. Thus, the problem is to analyse the values of metrics for a complex business process. In this paper we extend our previous work on analysis of secure orchestration with quantifiable properties. We show how to define, verify and enforce quantitative security requirements in one framework with other security properties. The proposed approach should help to select the most suitable service architecture and guarantee fulfilment of the declared security requirements.

Hearing and hearing disorders among classical and rock/jazz musicians was investigated. Pure tone audiometry was done in 140 classical and 139 rock/jazz musicians. The rock/jazz musicians answered a questionnaire concerning hearing disorders and psychosocial exposure. All results were compared to age appropriate reference materials. Hearing thresholds showed a notch configuration in both classical and rock/jazz musicians indicating the inclusion of high sound levels but an overall well-preserved hearing thresholds. Female musicians had significantly better hearing thresholds in the high-frequency area than males. Rock/jazz musicians showed slight worse hearing thresholds as compared to classical musicians. When assessing hearing disorders, a large number of rock/jazz musicians suffered from different hearing disorders (74%). Hearing loss, tinnitus and hyperacusis were the most common disorders and were significantly more frequent in comparison with different reference populations. Among classical musicians, no extended negative progress of the pure tone hearing threshold values was found in spite of the continued 16 years of musical noise exposure. In rock/jazz musicians, there was no relationships between psychosocial factors at work and hearing disorders. The rock/jazz musicians reported low stress and high degree of energy. On the average, the rock/jazz musicians reported higher control, lower stress and higher energy than a reference material of white-collar workers.
Full Text Available Musical training has been shown to have positive effects on several aspects of speech processing, however, the effects of musical training on the neural processing of speech prosody conveying distinct emotions are yet to be better understood. We used functional magnetic resonance imaging (fMRI to investigate whether the neural responses to speech prosody conveying happiness, sadness, and fear differ between musicians and non-musicians. Differences in processing of emotional speech prosody between the two groups were only observed when sadness was expressed. Musicians showed increased activation in the middle frontal gyrus, the anterior medial prefrontal cortex, the posterior cingulate cortex and the retrosplenial cortex. Our results suggest an increased sensitivity of emotional processing in musicians with respect to sadness expressed in speech, possibly reflecting empathic processes.

In a follow-up experiment, listeners’ pupil dilations were measured as an indicator of the required effort in performing the same pitch discrimination task for conditions of varying resolvability and task difficulty...... abilities in musicians are unlikely to be related to higher peripheral frequency selectivity and may suggest an enhanced pitch representation at more central stages of the auditory system in musically trained listeners....

Working memory (WM) performance in humans can be improved by structuring and organizing the material to be remembered. For visual and verbal information, this process of structuring has been associated with the involvement of a prefrontal-parietal network, but for non-verbal auditory material, the brain areas that facilitate WM for structured information have remained elusive. Using functional magnetic resonance imaging, this study compared neural correlates underlying encoding and rehearsal of auditory WM for structured and unstructured material. Musicians and non-musicians performed a WM task on five-tone sequences that were either tonally structured (with all tones belonging to one tonal key) or tonally unstructured (atonal) sequences. Functional differences were observed for musicians (who are experts in the music domain), but not for non-musicians - The right pars orbitalis was activated more strongly in musicians during the encoding of unstructured (atonal) vs. structured (tonal) sequences. In addition, data for musicians showed that a lateral (pre)frontal-parietal network (including the right premotor cortex, right inferior precentral sulcus and left intraparietal sulcus) was activated during WM rehearsal of structured, as compared with unstructured, sequences. Our findings indicate that this network plays a role in strategy-based WM for non-verbal auditory information, corroborating previous results showing a similar network for strategy-based WM for visual and verbal information. © 2010 The Authors.

Full Text Available Abstract Background Research comparing the frequency of musculoskeletal complaints between musicians and non-musicians is scarce. The aim of this study was to compare the prevalence of musculoskeletal complaints between musicians and non-musicians. Methods A cross-sectional study in 3215 students from three music academies (n = 345 and one medical school (n = 2870 in The Netherlands was performed, using an electronic questionnaire. The questionnaire included socio-demographic characteristics, use of music instruments and the occurrence of musculoskeletal complaints in six body regions. Questions were related to musculoskeletal complaints over the last twelve months and at the time of the questionnaire. Chi-square, t-tests and Kruskal-Wallis tests were used for comparison between the two groups. The association between musculoskeletal complaints and possible predictors was analyzed using a logistic and Poisson regression. Results Eighty-seven music academy students and 503 medical students returned the questionnaire, of which respectively eighty-three and 494 were included in the study. Seventy-four music academy students (89.2% reported one or more musculoskeletal complaints during the last twelve months, compared to 384 (77.9% medical students (p = 0.019. Moreover 52 music academy students (62.7% and 211 medical students (42.7% reported current musculoskeletal complaints (p = 0.001. The Odds ratio (OR for the development of musculoskeletal complaints during the last twelve months in music academy students versus medical students is 2.33 (95% CI 1.61–3.05, p = 0.022. The OR at the time of the questionnaire is 2.25 (95% CI 1.77–2.73, p = 0.001. The total number of complaints have been modeled by employing a Poisson regression; the results show that non-musicians have on average less complaints than musicians (p = 0.01. The adjusted means are 2.90 (95% CI 2.18–3.63 and 1.83 (95% CI 1.63–2.04 respectively for
Full Text Available Considering the long-term talent development, from the moment of its recognition to the moment when an adult is confronted with the necessity of integration in the professional music and life streams, we wonder whether education satisfies the needs of talents and provides, in the long run, the necessary knowledge and skills. The aim of this research was to investigate: (1 the initial motivation for learning music and expectations from music education; (2 the course of development of young musicians (the degree of self-actualisation, developmental perspectives, evaluation of music education and (3 outcomes of music education and development of the professional career. The sample (N=487 consisted of five subsamples: music kindergarten pupils, students of primary music schools, students of secondary music schools, university students of music and teachers at music schools and universities. The paper analyses psychological, educational and professional aspects of education of musically gifted pupils and students, as well as music teachers in five successive age groups. The results indicate that with an increase in age there is a considerable increase in the variety and scope of expectations and a higher aspiration towards personal, educational and professional lifelong improvement, while, at the same time, there is a considerable decrease in the level of fulfilment of expectations and the level of assessment of self-actualisation. This is indicative of a continuously present feeling of “hidden underachievement” in the group of (relatively successful young musicians and professionals. Analysis of respondents’ answers points out to the existence of still traditional system of music education, which lacks flexibility and innovation and fails to provide a sufficient level of transferable knowledge and skills. The findings point out to a whole cluster of controversies demanding further reconsideration and (redesigning of the curriculum of (high
In spring 1873, two years after France’s devastating defeat in the Franco-Prussian war, Georges Hartmann hired Edouard Colonne to conduct eight “Concerts Nationals”. With them, he aimed to promote French music, especially that which he published. The concerts attracted a large, enthusiastic crowd, but lost money. A year later Colonne founded his own orchestra, subsequently known as the Concerts Colonne. Their challenge was to attract a mass public for serious orchestral music, successfully co...

Little is known about the underlying neurobiology of rhythm and beat perception, despite its universal cultural importance. Here we used functional magnetic resonance imaging to study rhythm perception in musicians and non-musicians. Three conditions varied in the degree to which external reinforcement versus internal generation of the beat was required. The ‘Volume’ condition strongly externally marked the beat with volume changes, the ‘Duration’ condition marked the beat with weaker accents arising from duration changes, and the ‘Unaccented’ condition required the beat to be entirely internally generated. In all conditions, beat rhythms compared to nonbeat control rhythms revealed putamen activity. The presence of a beat was also associated with greater connectivity between the putamen and the supplementary motor area (SMA), the premotor cortex (PMC) and auditory cortex. In contrast, the type of accent within the beat conditions modulated the coupling between premotor and auditory cortex, with greater modulation for musicians than non-musicians. Importantly, the putamen's response to beat conditions was not due to differences in temporal complexity between the three rhythm conditions. We propose that a cortico-subcortical network including the putamen, SMA, and PMC is engaged for the analysis of temporal sequences and prediction or generation of putative beats, especially under conditions that may require internal generation of the beat. The importance of this system for auditory-motor interaction and development of precisely timed movement is suggested here by its facilitation in musicians. PMID:19515922

Determine the safety and tolerance of mesotherapy as a technique for the treatment of musculoskeletal complaints in musicians. 67 patients (55.2% women) were subjected to a total of 267 mesotherapy sessions. A mesotherapy needle or normal needle was used randomly. The drugs employed were thiocolchicoside and diazepam as muscular relaxants, pentoxifylline or buflomedil as vasodilators, and piroxicam as an anti-inflammatory, as directed. A visual analogue scale was used to quantify the pain produced by the microinjections as well as the degree of immediate and midterm side effects as reported on a standard questionnaire. A mean of 155.5 microinjections were performed per session, of which 45.6% were perceived as painful by the patient with a mean severity of 4.3 out of 10. The pain reduced to 0.5 out of 10 after 24 hours. The most sensitive areas were the levator scapulae and splenius muscles. Systemic symptoms were reported by 5.99% of the musicians after the mesotherapy sessions (muscular weakness 1.5%, rash 1.5%, drowsiness 1.1% and itching 1.1%, being the most frequent). The mean severity of these symptoms was 2.77 out of 10. In all cases the symptoms had completely disappeared after 24 hours. No patient referred to signs of local or systemic infection. The application of drugs by means of subcutaneous injections (mesotherapy) in musicians is a technique that is safe, well tolerated, and without any severe complications.

Numerous studies have shown that musicians outperform nonmusicians on a variety of tasks. Here we provide the first evidence that musicians have superior auditory recognition memory for both musical and nonmusical stimuli, compared to nonmusicians. However, this advantage did not generalize to the visual domain. Previously, we showed that auditory recognition memory is inferior to visual recognition memory. Would this be true even for trained musicians? We compared auditory and visual memory ...

Full Text Available Musical competence may confer cognitive advantages that extend beyond processing of familiar musical sounds. Behavioural evidence indicates a general enhancement of both working memory and attention in musicians. It is possible that musicians, due to their training, are better able to maintain focus on task-relevant stimuli, a skill which is crucial to working memory. We measured the blood oxygenation-level dependent (BOLD activation signal in musicians and non-musicians during working memory of musical sounds to determine the relation among performance, musical competence and generally enhanced cognition. All participants easily distinguished the stimuli. We tested the hypothesis that musicians nonetheless would perform better, and that differential brain activity would mainly be present in cortical areas involved in cognitive control such as the lateral prefrontal cortex. The musicians performed better as reflected in reaction times and error rates. Musicians also had larger BOLD responses than non-musicians in neuronal networks that sustain attention and cognitive control, including regions of the lateral prefrontal cortex, lateral parietal cortex, insula, and putamen in the right hemisphere, and bilaterally in the posterior dorsal prefrontal cortex and anterior cingulate gyrus. The relationship between the task performance and the magnitude of the BOLD response was more positive in musicians than in non-musicians, particularly during the most difficult working memory task. The results confirm previous findings that neural activity increases during enhanced working memory performance. The results also suggest that superior working memory task performance in musicians rely on an enhanced ability to exert sustained cognitive control. This cognitive benefit in musicians may be a consequence of focused musical training.

Full Text Available Wind instrumentalists require a sophisticated functioning of their respiratory system to control their air stream, which provides the power for optimal musical performance. The air supply must be delivered into the instrument in a steady and controlled manner and with enough power by the action of the expiratory musculature to produce the desired level of sound at the correct pitch. It is suggested that playing posture may have an impact on the abdominal muscle activity controlling this expired air, but there is no research on musicians to support this theory. This study evaluated chest and abdominal expansion, via respiratory inductive plethysmography, as well as activation patterns of lower and upper abdominal musculature, using surface electromyography, during performance of a range of typical orchestral repertoire by 113 woodwind and brass players. Each of the five orchestral excerpts was played in one of four randomly allocated postures: standing; sitting flat; sitting inclined forwards; and sitting inclined backwards.Musicians showed a clear preference for playing in standing rather than sitting. In standing, the chest expansion range and maximum values were greater (p<0.01, while the abdominal expansion was less than in all sitting postures (p<0.01. Chest expansion patterns did not vary between the three sitting postures, while abdominal expansion was reduced in the forward inclined posture compared to the other sitting postures (p<0.05. There was no significant variation in abdominal muscle activation between the sitting postures, but the level of activation in sitting was only 2/3 of the significantly higher level observed in standing (p<0.01.This study has demonstrated significant differences in respiratory mechanics between sitting and standing postures in wind musicians during playing of typical orchestral repertoire. Further research is needed to clarify the complex respiratory mechanisms supporting musical performance.

Full Text Available We study the relations between a contract automata and an interaction model. In the former model, distributed services are abstracted away as automata - oblivious of their partners - that coordinate with each other through an orchestrator. The interaction model relies on channel-based asynchronous communication and choreography to coordinate distributed services. We define a notion of strong agreement on the contract model, exhibit a natural mapping from the contract model to the interaction model, and give conditions to ensure that strong agreement corresponds to well-formed choreography.

Full Text Available PURPOSE: Musicians experience a large amount of information transfer and integration of complex sensory, motor, and auditory processes when training and playing musical instruments. Therefore, musicians are a useful model in which to investigate neural adaptations in the brain. METHODS: Here, based on diffusion-weighted imaging, probabilistic tractography was used to determine the architecture of white matter anatomical networks in musicians and non-musicians. Furthermore, the features of the white matter networks were analyzed using graph theory. RESULTS: Small-world properties of the white matter network were observed in both groups. Compared with non-musicians, the musicians exhibited significantly increased connectivity strength in the left and right supplementary motor areas, the left calcarine fissure and surrounding cortex and the right caudate nucleus, as well as a significantly larger weighted clustering coefficient in the right olfactory cortex, the left medial superior frontal gyrus, the right gyrus rectus, the left lingual gyrus, the left supramarginal gyrus, and the right pallidum. Furthermore, there were differences in the node betweenness centrality in several regions. However, no significant differences in topological properties were observed at a global level. CONCLUSIONS: We illustrated preliminary findings to extend the network level understanding of white matter plasticity in musicians who have had long-term musical training. These structural, network-based findings may indicate that musicians have enhanced information transmission efficiencies in local white matter networks that are related to musical training.

A chord deviating from the conventions of Western tonal music elicits an early right anterior negativity (ERAN) in inferofrontal brain regions. Here, we tested whether the ERAN is modulated by expertise in more than one music culture, as typical of folk musicians. Finnish folk musicians and nonmusicians participated in electroencephalography recordings. The cadences consisted of seven chords. In incongruous cadences, the third, fifth, or seventh chord was a Neapolitan. The ERAN to the Neapolitans was enhanced in folk musicians compared to nonmusicians. Folk musicians showed an enhanced P3a for the ending Neapolitan. The Neapolitan at the fifth position was perceived differently and elicited a late enhanced ERAN in folk musicians. Hence, expertise in more than one music culture seems to modify chord processing by enhancing the ERAN to ambivalent chords and the P3a to incongruous chords, and by altering their perceptual attributes.

Full Text Available Our focus in this study was to assess hearing thresholds and the prevalence and characteristics of tinnitus in a large group of rock musicians based in Norway. A further objective was to assess related factors such as exposure, instrument category, and the preventive effect of hearing protection. The study was a cross-sectional survey of rock musicians selected at random from a defined cohort of musicians. A random control group was included for comparison. We recruited 111 active musicians from the Oslo region, and a control group of 40 nonmusicians from the student population at the University of TromsØ. The subjects were investigated using clinical examination, pure tone audiometry, tympanometry, and a questionnaire. We observed a hearing loss in 37.8% of the rock musicians. Significantly poorer hearing thresholds were seen at most pure-tone frequencies in musicians than controls, with the most pronounced threshold shift at 6 kHz. The use of hearing protection, in particular custom-fitted earplugs, has a preventive effect but a minority of rock musicians apply them consistently. The degree of musical performance exposure was inversely related to the degree of hearing loss in our sample. Bass and guitar players had higher hearing thresholds than vocalists. We observed a 20% prevalence of chronic tinnitus but none of the affected musicians had severe tinnitus symptomatology. There was no statistical association between permanent tinnitus and hearing loss in our sample. We observed an increased prevalence of hearing loss and tinnitus in our sample of Norwegian rock musicians but the causal relationship between musical exposure and hearing loss or tinnitus is ambiguous. We recommend the use of hearing protection in rock musicians.

Despite the obvious importance of deciding which career to pursue, little is known about the influence of personality on career choice. Here we investigated the relation between sensation seeking, a supposedly innate personality trait, and career choice in classical and "rhythmic" students at the academies of music in Denmark. We…

Limited attention is paid to the hazards experienced by orchestra musicians in the occupational health and safety literature. Within that literature, the primary focus has been on noise exposure. A focus on this area is warranted because high sound pressure levels are a product of this work environment. However, in addition to being at risk for noise-induced hearing loss, workers are also at risk for musculoskeletal injury and illness related to stressful body postures held for prolonged work periods. The socio-political forces of employment may place workers at risk for mental health disorders (e.g., depression). The researchers distributed an anonymous survey to classical orchestra musicians in the southwestern United States. The survey inventoried several areas related to occupational health risks. Results suggest low health care-seeking behaviors relative to self-reported signs and symptoms of morbidity. Musicians also reported limited formal training and education regarding occupational health risks. Risk information was provided late in their professional development. This is a particular concern because of the young age at which music training is initiated. Copyright 2012, SLACK Incorporated.

This paper presents results of an investigation of room acoustic parameters those are appropriated particularly to perform a Javanese gamelan. The acoustic parameters were obtained by analysing simulated sounds of performance. Those simulated sounds were obtained by sound convolution technique of a dry sound signal of Javanese gamelan performance with impulse responses rooms whose appropriated reverberation time. The reverberation time were varied between 1.0s to 1.8s, those belong to the characteristic of Pendopo Mangkunegaran Surakarta. In this case, Pendopo Mangkunegaran is assumed as one of the most suitable concert halls for Javanese gamelan performance. To obtain the acoustic parameters, we used a psycho-acoustics measurement based on paired comparison test that having different of acoustic parameters to determine the most comfortable one to majority of respondents. The respondents who have participated in this research composed of a group of professional musicians of Javanese gamelan and groups of audience who are not musician, nevertheless part of them were familiar with Javanese gamelan music. The comparison test gave results and showed majority of respondents of group of musicians had a notion sound reverberation time of 1.2s was most comfortable. This corresponds to +6.2dB, clarity and 74% definition. It means the appropriate acoustic condition allows musicians to recognize and distinguish clearly sound of each instrument being played. Meanwhile, group of audience had a notion reverberation time in a range of 1.2s - 1.6s was most comfortable. This range of reverberation time corresponds to +4dB to +6.2dB of clarity, and 66% to 74% of definition.

Changing labour conditions in the creative industries - with celebrations of autonomy and entrepreneurialism intertwined with increasing job insecurity, portfolio careers and short-term, project-based contracts - are often interpreted as heralding changes to employment relations more broadly. The position of musicians' labour in relation to these changes is unclear, however, given that these kinds of conditions have defined musicians' working practices over much longer periods of time (though they may have intensified due to well-documented changes to the music industry brought about by digitization and disintermediation). Musicians may thus be something of a barometer of current trends, as implied in the way that the musically derived label 'gig economy' is being used to describe the spread of precarious working conditions to broader sections of the population. This article, drawing on original qualitative research that investigated the working practices of musicians, explores one specific aspect of these conditions: whether musicians are self-consciously entrepreneurial towards their work and audience. We found that, while the musicians in our study are routinely involved in activities that could be construed as entrepreneurial, generally they were reluctant to label themselves as entrepreneurs. In part this reflected understandings of entrepreneurialism as driven by profit-seeking but it also reflected awareness that being a popular musician has always involved business and commercial dimensions. Drawing on theoretical conceptions of entrepreneurship developed by Joseph Schumpeter we highlight how the figure of the entrepreneur and the artist/musician share much in common and reflect various aspects of romantic individualism. Despite this, there are also some notable differences and we conclude that framing musicians' labour as entrepreneurial misrepresents their activities through an overemphasis on the economic dimensions of their work at the expense of the
Full Text Available Executive functions (EF are cognitive capacities that allow for planned, controlled behavior and strongly correlate with academic abilities. Several extracurricular activities have been shown to improve EF, however, the relationship between musical training and EF remains unclear due to methodological limitations in previous studies. To explore this further, two experiments were performed; one with 30 adults with and without musical training and one with 27 musically trained and untrained children (matched for general cognitive abilities and socioeconomic variables with a standardized EF battery. Furthermore, the neural correlates of EF skills in musically trained and untrained children were investigated using fMRI. Adult musicians compared to non-musicians showed enhanced performance on measures of cognitive flexibility, working memory, and verbal fluency. Musically trained children showed enhanced performance on measures of verbal fluency and processing speed, and significantly greater activation in pre-SMA/SMA and right VLPFC during rule representation and task-switching compared to musically untrained children. Overall, musicians show enhanced performance on several constructs of EF, and musically trained children further show heightened brain activation in traditional EF regions during task-switching. These results support the working hypothesis that musical training may promote the development and maintenance of certain EF skills, which could mediate the previously reported links between musical training and enhanced cognitive skills and academic achievement.

Does a combination of lifestyle pressures and personality, as reflected in genre, lead to the early death of popular musicians? We explored overall mortality, cause of death, and changes in patterns of death over time and by music genre membership in popular musicians who died between 1950 and 2014. The death records of 13,195 popular musicians were coded for age and year of death, cause of death, gender, and music genre. Musician death statistics were compared with age-matched deaths in the US population using actuarial methods. Although the common perception is of a glamorous, free-wheeling lifestyle for this occupational group, the figures tell a very different story. Results showed that popular musicians have shortened life expectancy compared with comparable general populations. Results showed excess mortality from violent deaths (suicide, homicide, accidental death, including vehicular deaths and drug overdoses) and liver disease for each age group studied compared with population mortality patterns. These excess deaths were highest for the under-25-year age group and reduced chronologically thereafter. Overall mortality rates were twice as high compared with the population when averaged over the whole age range. Mortality impacts differed by music genre. In particular, excess suicides and liver-related disease were observed in country, metal, and rock musicians; excess homicides were observed in 6 of the 14 genres, in particular hip hop and rap musicians. For accidental death, actual deaths significantly exceeded expected deaths for country, folk, jazz, metal, pop, punk, and rock.

Musical sounds, along with speech, are the most prominent sounds in our daily lives. They are highly dynamic, yet well structured in the temporal domain in a hierarchical manner. The temporal structures enhance the predictability of musical sounds. Western music provides an excellent example: while time intervals between musical notes are highly variable, underlying beats can be realized. The beat-level temporal structure provides a sense of regular pulses. Beats can be further organized into units, giving the percept of alternating strong and weak beats (i.e. metrical structure or meter). Examining neural processing at the meter level offers a unique opportunity to understand how the human brain extracts temporal patterns, predicts future stimuli and optimizes neural resources for processing. The present study addresses two important questions regarding meter processing, using the mismatch negativity (MMN) obtained with electroencephalography (EEG): 1) how tempo (fast vs. slow) and type of metrical structure (duple: two beats per unit vs. triple: three beats per unit) affect the neural processing of metrical structure in non-musically trained individuals, and 2) how early music training modulates the neural processing of metrical structure. Metrical structures were established by patterns of consecutive strong and weak tones (Standard) with occasional violations that disrupted and reset the structure (Deviant). Twenty non-musicians listened passively to these tones while their neural activities were recorded. MMN indexed the neural sensitivity to the meter violations. Results suggested that MMNs were larger for fast tempo and for triple meter conditions. Further, 20 musically trained individuals were tested using the same methods and the results were compared to the non-musicians. While tempo and meter type similarly influenced MMNs in both groups, musicians overall exhibited significantly reduced MMNs, compared to their non-musician counterparts. Further analyses

Numerous studies have shown that musicians outperform nonmusicians on a variety of tasks. Here we provide the first evidence that musicians have superior auditory recognition memory for both musical and nonmusical stimuli, compared to nonmusicians. However, this advantage did not generalize to the visual domain. Previously, we showed that auditory recognition memory is inferior to visual recognition memory. Would this be true even for trained musicians? We compared auditory and visual memory in musicians and nonmusicians using familiar music, spoken English, and visual objects. For both groups, memory for the auditory stimuli was inferior to memory for the visual objects. Thus, although considerable musical training is associated with better musical and nonmusical auditory memory, it does not increase the ability to remember sounds to the levels found with visual stimuli. This suggests a fundamental capacity difference between auditory and visual recognition memory, with a persistent advantage for the visual domain.

Joint hypermobility is considered to be both an advantage and a disadvantage. However, the degree of hypermobility in members of particular occupations requiring intense physical activity and the nature of the association between symptoms referable to specific joints and their hypermobility are unknown. We interviewed 660 musicians (300 women and 360 men) about work-related symptoms such as joint pain and swelling and examined them for joint hypermobility according to a standard protocol. We then determined the relation between the mobility of their fingers, thumbs, elbows, knees, and spine and any symptoms referable to these regions. Five of the 96 musicians (5 percent) with hypermobility of the wrists, mostly instrumentalists who played the flute, violin, or piano, had pain and stiffness in this region, whereas 100 of the 564 musicians (18 percent) without such hypermobility had symptoms (P = 0.001). Hypermobility of the elbow was associated with symptoms in only 1 of 208 musicians (< 1 percent), whereas 7 of 452 (2 percent) without this hypermobility had symptoms (P = 0.45). Among the 132 musicians who had hypermobile knees, 6 (5 percent) had symptoms, whereas only 1 of 528 (< 1 percent) with normal knees had symptoms (P < 0.001). Of the 462 musicians who had normal mobility of the spine, 50 (11 percent) had symptoms involving the back, as compared with 46 of the 198 musicians (23 percent) who had hypermobility of the spine (P < 0.001). Among musicians who play instruments requiring repetitive motion, hypermobility of joints such as the wrists and elbows may be an asset, whereas hypermobility of less frequently moved joints such as the knees and spine may be a liability.

Mental rotation of body parts engages cortical-subcortical areas that are actually involved in the execution of a movement. Musicians' dystonia is a type of focal hand dystonia that is grouped together with writer's cramp under the rubric of "occupational dystonia", but it is unclear to which extent these two disorders share common pathophysiological mechanisms. Previous research has demonstrated patients with writer's cramp to have deficits in mental rotation of body parts. It is unknown whether patients with musicians' dystonia would display similar deficits, reinforcing the concept of shared pathophysiology. Eight patients with musicians' dystonia and eight healthy musicians matched for age, gender and musical education, performed a number of tasks assessing mental rotation of body parts and objects as well as verbal and spatial working memories abilities. There were no differences between patients and healthy musicians as to accuracy and reaction times in any of the tasks. Patients with musicians' dystonia have intact abilities in mentally rotating body parts, suggesting that this disorder relies on a highly selective disruption of movement planning and execution that manifests only upon playing a specific instrument. We further demonstrated that mental rotation of body parts and objects engages, at least partially, different cognitive networks. Copyright © 2016 Elsevier Inc. All rights reserved.

Creativity has been defined as the ability to produce work that is novel, high in quality, and appropriate to an audience. While the nature of the creative process is under debate, many believe that creativity relies on real-time combinations of known neural and cognitive processes. One useful model of creativity comes from musical improvisation, such as in jazz, in which musicians spontaneously create novel sound sequences. Here we use jazz musicians to test the hypothesis that individuals with training in musical improvisation, which entails creative generation of musical ideas, might process expectancy differently. We compare jazz improvisers, non-improvising musicians, and non-musicians in the domain-general task of divergent thinking, as well as the musical task of preference ratings for chord progressions that vary in expectation while EEGs were recorded. Behavioral results showed for the first time that jazz musicians preferred unexpected chord progressions. ERP results showed that unexpected stimuli elicited larger early and mid-latency ERP responses (ERAN and P3b), followed by smaller long-latency responses (Late Positivity Potential) in jazz musicians. The amplitudes of these ERP components were significantly correlated with behavioral measures of fluency and originality on the divergent thinking task. Together, results highlight the role of expectancy in creativity. Copyright © 2017 Elsevier Inc. All rights reserved.

The music genre of jazz is commonly associated with creativity. However, this association has hardly been formally tested. Therefore, this study aimed at examining whether jazz musicians actually differ in creativity and personality from musicians of other music genres. We compared students of classical music, jazz music, and folk music with respect to their musical activities, psychometric creativity and different aspects of personality. In line with expectations, jazz musicians are more frequently engaged in extracurricular musical activities, and also complete a higher number of creative musical achievements. Additionally, jazz musicians show higher ideational creativity as measured by divergent thinking tasks, and tend to be more open to new experiences than classical musicians. This study provides first empirical evidence that jazz musicians show particularly high creativity with respect to domain-specific musical accomplishments but also in terms of domain-general indicators of divergent thinking ability that may be relevant for musical improvisation. The findings are further discussed with respect to differences in formal and informal learning approaches between music genres.

The experience of hearing an exceptional symphony orchestra perform in an excel- lent concert hall can be profound and moving, causing a level of excitement not often reached for listeners. Romantic period style orchestral music, recognized for validating the use of intense emotion for aesthetic pleasure, was the last significant development in the history of the orchestra. In an age where orchestral popularity is waning, the possibil- ity of evolving the orchestral sound in our modern era exists through the combination of our current understanding of instrument directivity patterns and their interaction with architectural acoustics. With the aid of wave field synthesis (WFS), newly proposed variations on orchestral layouts are tested virtually using a 64-channel WFS array. Each layout is objectively and subjectively compared for determination of which layout could optimize the sound of the orchestra and revitalize the excitement of the performance.

Full Text Available Sound is an inseparable part of human life and provides us with lovely experiences such as listening to music. Musicians from classical orchestras to rock groups are exposed to high decibel of sounds. Musicians playing percussion musical instruments are exposed to high level of impact noise and players of Brass musical instruments are highly exposed to noise peaks higher than 100dB. Woodwind players are enduring the risk of posing directly in front of Brass players. Based on the above-mentioned risks for hearing loss clinical consideration of noise induced hearing loss in musicians is highly required. In the current study we were aimed at examining hearing stratus of classic and traditional musicians by means of pure tone audiometry in Islamic Republic of Iran Broadcasting. 33 subjects were evaluated aged between 22 to 59 years old. Their musical experience was variable between 6 to 45 years. The study demonstrated that most of the musicians in this study suffered bilateral high frequency hearing loss with a notch in the frequency range of 4-8 KHz.

Maintaining good health is essential for touring musicians and singers. The stressful demands of touring may impact food choices, leading to detrimental effects on health and performance. This exploratory pilot study aimed to assess factors affecting healthful eating of touring musicians and singers. A 46-item survey was used to assess food- and nutrition-related attitudes, knowledge and behaviors, and environmental factors, as well as lifestyle, musical background, and demographic data. Participants (n=35) were recruited from a musicians' assistance foundation as well as touring musical theater productions and a music festival. Results indicate that touring musicians and singers had positive attitudes regarding healthful foods. Of 35 respondents, 80.0% indicated eating healthful food was important to them. Respondents reported feeling confident selecting (76.5%) and preparing (82.4%) healthful foods; however, they showed uncertainty when determining if carbohydrate-containing foods should be consumed or avoided. Respondents indicated environmental factors including availability and cost of healthy food options and tour schedules limited access to healthful foods. Venues (73.5%), fast food restaurants (67.6%), and airports (64.7%) were the most frequently identified locations in need of offering more healthful food choices. Respondents (52.9%) indicated more support from others while touring would help them make healthier food choices. More research is needed to develop mobile wellness programs as well as performance-based nutrition guidelines for musicians and singers that address the unique demands associated with touring.
Full Text Available The dorsal striatum (caudate/putamen is a node of the cortico-striato-pallido-thalamo-cortical (CSPTC motor circuit, which plays a central role in skilled motor learning, a critical feature of musical performance. The dorsal striatum receives input from a large part of the cerebral cortex, forming a hub in the cortical-subcortical network. This study sought to examine how the functional network of the dorsal striatum differs between musicians and nonmusicians.Resting state functional magnetic resonance imaging (fMRI data were acquired from female university students majoring in music and nonmusic disciplines. The data were subjected to graph theoretical analysis and functional connectivity analysis. The graph theoretical analysis of the entire brain revealed that the degree, which represents the number of connections, of the bilateral putamen was significantly lower in musicians than in nonmusicians. The functional connectivity analysis indicated that compared with nonmusicians, musicians had significantly decreased connectivity between the left putamen and bilateral frontal operculum and between the left caudate nucleus and cerebellum. In conclusion, compared with nonmusicians, female musicians have a smaller functional network of the dorsal striatum, with decreased connectivity. These data are consistent with previous anatomical studies reporting a reduced volume of the dorsal striatum in musicians and ballet dancers. To the best of our knowledge, this is the first study suggesting that long-term musical training results in a less extensive or selective functional network of the dorsal striatum.
Full Text Available An efficient and fast auditory–motor network is a basic resource for trained musicians due to the importance of motor anticipation of sound production in musical performance. When playing an instrument, motor performance always goes along with the production of sounds and the integration between both modalities plays an essential role in the course of musical training. The aim of the present study was to investigate the role of task-irrelevant auditory feedback during motor performance in musicians using a serial reaction time task (SRTT. Our hypothesis was that musicians, due to their extensive auditory–motor practice routine during musical training, have a superior performance and learning capabilities when receiving auditory feedback during SRTT relative to musicians performing the SRTT without any auditory feedback. Here we provide novel evidence that task-irrelevant auditory feedback is capable to reinforce SRTT performance but not learning, a finding that might provide further insight into auditory-motor integration in musicians on a behavioral level.

This article describes the relationship of mothers' orchestration of daily occupations, the specialized maternal work of parenting a child with a disability, and the mother's subjective well-being. Mothers' daily occupations and subjective well-being were studied using multiple in-depth interviews, participant observation of a day's round of occupations, and scales of well-being. Data were treated to a recursive analysis, which included theoretical notes generated during transcriptions that identified important themes and additional points of inquiry, line-by-line coding of transcripts, and theoretical sorting of codes and regrouping, recoding. To account for patterns in the data, a relational analysis was conducted that included the generation of metaphors. Emergent findings of this analysis identified the mothers' guiding occupational motif and eight processes of orchestration in their daily routines. The occupational motif, the embrace of paradox, directed the mother's orchestration of daily occupations. The orchestration processes included planning, organizing, balancing, anticipating, interpreting, forecasting, perspective shifting, and meaning making. Examples illustrate the maternally driven and child-sensitive nature of these processes. In their daily rounds, the mothers studied were attentive to the manner and method with which they interacted with their children to produce child-contingent occupations commensurate with their values of being a good mother. Using these orchestration processes, mothers made sense of their past, designed their present, and planned for their future within their daily occupational rounds for themselves and family members.

Several studies have found that musicians perform better than nonmusicians in memory tasks, but this is not always the case, and the strength of this apparent advantage is unknown. Here, we conducted a meta-analysis with the aim of clarifying whether musicians perform better than nonmusicians in memory tasks. Education Source; PEP (WEB)-Psychoanalytic Electronic Publishing; Psychology and Behavioral Science (EBSCO); PsycINFO (Ovid); PubMed; ScienceDirect-AllBooks Content (Elsevier API); SCOPUS (Elsevier API); SocINDEX with Full Text (EBSCO) and Google Scholar were searched for eligible studies. The selected studies involved two groups of participants: young adult musicians and nonmusicians. All the studies included memory tasks (loading long-term, short-term or working memory) that contained tonal, verbal or visuospatial stimuli. Three meta-analyses were run separately for long-term memory, short-term memory and working memory. We collected 29 studies, including 53 memory tasks. The results showed that musicians performed better than nonmusicians in terms of long-term memory, g = .29, 95% CI (.08-.51), short-term memory, g = .57, 95% CI (.41-.73), and working memory, g = .56, 95% CI (.33-.80). To further explore the data, we included a moderator (the type of stimulus presented, i.e., tonal, verbal or visuospatial), which was found to influence the effect size for short-term and working memory, but not for long-term memory. In terms of short-term and working memory, the musicians' advantage was large with tonal stimuli, moderate with verbal stimuli, and small or null with visuospatial stimuli. The three meta-analyses revealed a small effect size for long-term memory, and a medium effect size for short-term and working memory, suggesting that musicians perform better than nonmusicians in memory tasks. Moreover, the effect of the moderator suggested that, the type of stimuli influences this advantage.

As one major line of research on brain plasticity, many imaging studies have been conducted to identify the functional and structural reorganization associated with musical expertise. Based on previous behavioral research, the present study used functional magnetic resonance imaging to identify the neural correlates of superior verbal memory performance in musicians. Participants with and without musical training performed a verbal memory task to first encode a list of words auditorily delivered and then silently recall as many words as possible. They performed in separate blocks a control task involving pure tone pitch judgment. Post-scan recognition test showed better memory performance in musicians than non-musicians. During memory retrieval, the musicians showed significantly greater activations in bilateral though left-lateralized visual cortex relative to the pitch judgment baseline. In comparison, no such visual cortical activations were found in the non-musicians. No group differences were observed during the encoding stage. The results echo a previous report of visual cortical activation during verbal memory retrieval in the absence of any visual sensory stimulation in the blind population, who are also known to possess superior verbal memory. It is suggested that the visual cortex can be recruited to serve as extra memory resources and contributes to the superior verbal memory in special situations. While in the blind population, such cross-modal functional reorganization may be induced by sensory deprivation; in the musicians it may be induced by the long-term and demanding nature of musical training to use as much available neural resources as possible. 2010 IBRO.

Brief biographical information on four great jazz tenor saxophone players of the past is presented to illustrate the similar psychosocial stressors these men seemed to experience, namely, severe substance abuse, haphazard working conditions, lack of acceptance of their art form in the United States, marital and family discord, and a vagabond life style. Ages at death of 80 great jazz musicians may indicate that the stressful life style of jazz musicians may be reflected in a shortened life span, but a control group is needed.

Expertise in music has been investigated for decades and the results have been applied not only in composition, performance and music education, but also in understanding brain plasticity in a larger context. Several studies have revealed a strong connection between auditory and motor processes and listening to and performing music, and music imagination. Recently, as a logical next step in music and movement, the cognitive and affective neurosciences have been directed towards expertise in dance. To understand the versatile and overlapping processes during artistic stimuli, such as music and dance, it is necessary to study them with continuous naturalistic stimuli. Thus, we used long excerpts from the contemporary dance piece Carmen presented with and without music to professional dancers, musicians, and laymen in an EEG laboratory. We were interested in the cortical phase synchrony within each participant group over several frequency bands during uni- and multimodal processing. Dancers had strengthened theta and gamma synchrony during music relative to silence and silent dance, whereas the presence of music decreased systematically the alpha and beta synchrony in musicians. Laymen were the only group of participants with significant results related to dance. Future studies are required to understand whether these results are related to some other factor (such as familiarity to the stimuli), or if our results reveal a new point of view to dance observation and expertise.

Although cognitive music psychology has a long tradition of expert–novice comparisons, experimental training studies are rare. Studies on the learning progress of trained novices in hearing harmonic relationships are still largely lacking. This paper presents a simple training concept using the example of tone/triad similarity ratings, demonstrating the gradual progress of non-musicians compared to musical experts: In a feedback-based “rapid learning” paradigm, participants had to decide for single tones and chords whether paired sounds matched each other well. Before and after the training sessions, they provided similarity judgments for a complete set of sound pairs. From these similarity matrices, individual relational sound maps, intended to display mental representations, were calculated by means of non-metric multidimensional scaling (NMDS), and were compared to an expert model through procrustean transformation. Approximately half of the novices showed substantial learning success, with some participants even reaching the level of professional musicians. Results speak for a fundamental ability to quickly train an understanding of harmony, show inter-individual differences in learning success, and demonstrate the suitability of the scaling method used for learning research in music and other domains.

Although cognitive music psychology has a long tradition of expert-novice comparisons, experimental training studies are rare. Studies on the learning progress of trained novices in hearing harmonic relationships are still largely lacking. This paper presents a simple training concept using the example of tone/triad similarity ratings, demonstrating the gradual progress of non-musicians compared to musical experts: In a feedback-based "rapid learning" paradigm, participants had to decide for single tones and chords whether paired sounds matched each other well. Before and after the training sessions, they provided similarity judgments for a complete set of sound pairs. From these similarity matrices, individual relational sound maps, intended to display mental representations, were calculated by means of non-metric multidimensional scaling (NMDS), and were compared to an expert model through procrustean transformation. Approximately half of the novices showed substantial learning success, with some participants even reaching the level of professional musicians. Results speak for a fundamental ability to quickly train an understanding of harmony, show inter-individual differences in learning success, and demonstrate the suitability of the scaling method used for learning research in music and other domains. Results are discussed in the context of the "giftedness" debate.

Expertise in music has been investigated for decades and the results have been applied not only in composition, performance and music education, but also in understanding brain plasticity in a larger context. Several studies have revealed a strong connection between auditory and motor processes and listening to and performing music, and music imagination. Recently, as a logical next step in music and movement, the cognitive and affective neurosciences have been directed towards expertise in dance. To understand the versatile and overlapping processes during artistic stimuli, such as music and dance, it is necessary to study them with continuous naturalistic stimuli. Thus, we used long excerpts from the contemporary dance piece Carmen presented with and without music to professional dancers, musicians, and laymen in an EEG laboratory. We were interested in the cortical phase synchrony within each participant group over several frequency bands during uni- and multimodal processing. Dancers had strengthened theta and gamma synchrony during music relative to silence and silent dance, whereas the presence of music decreased systematically the alpha and beta synchrony in musicians. Laymen were the only group of participants with significant results related to dance. Future studies are required to understand whether these results are related to some other factor (such as familiarity to the stimuli), or if our results reveal a new point of view to dance observation and expertise.

Full Text Available The use of intracarotid propofol procedure (IPP when assessing musical lateralization has not been reported in literature up to now. This procedure (similar to Wada Test has provided the opportunity to investigate not only lateralization of language and memory functions on epileptic patients but also offers a functional mapping approach with superior spatial and temporal resolution to analyze the lateralization of musical abilities. Findings in literature suggest that musical training modifies functional and structural brain organization. We studied hemispheric lateralization in a professional musician, a 33 years old woman with refractory left medial temporal lobe epilepsy. A longitudinal neuropsychological study was performed over a period of 21 months. Before epilepsy surgery, musical abilities, language and memory were tested during IPP by means of a novel and exhaustive neuropsychological battery focusing on the processing of music. We used a selection of stimuli to analyze listening, score reading, and tempo discrimination. Our results suggested that IPP is an excellent method to determine not only language, semantic and episodic memory, but also musical dominance in a professional musician who may be candidate for epilepsy surgery. Neuropsychological testing revealed that right hemisphere’s patient is involved in semantic and episodic musical memory processes, whereas her score reading and tempo processing require contribution from both hemispheres. At 1-year follow-up, outcome was excellent with respect to seizures and professional skills, meanwhile cognitive abilities improved. These findings indicate that IPP helps to predict who might be at risk for postoperative musical, language and memory deficits after epilepsy surgery. Our research suggests that musical expertise and epilepsy critically modifies long-term memory processes and induces brain structural and functional plasticity.

Rock musicians are known to have an increased prevalence of hearing loss and tinnitus. The aims of the present study were to examine the distribution of anxiety and depression symptoms among rock musicians with or without tinnitus and how these mental health indicators and internal locus of control influenced upon their tinnitus symptom concerns and the degree to which the tinnitus affected their lives. The study was a questionnairebased cross-sectional survey of subjects selected from a cohort of rock musicians. We recruited 111 active musicians from the Oslo region, and a control group of 40 non-musicians from the student population at the University of Tromso. Among the rock musicians 19.8% reported permanent tinnitus vs. 0% among the controls. Musicians more often reported anxiety symptoms than controls (35.1% vs. 17.5%), however this prevalence was not different in musicians with and without tinnitus. Tinnitus-affected musicians reported depressive symptoms, significantly more than controls (13.6% vs. 5%). Rock musicians consumed more alcohol than controls, but alcohol consumption was unrelated to severity of tinnitus. Drug abuse was not more prevalent in rock musicians than in controls. Duration of tinnitus, internal locus of control, sleep disturbance and anxiety were significant predictors of how affected and how concerned musicians were about their tinnitus. Rock musicians are at risk for the development of chronic tinnitus, and they have an increased prevalence of anxiety. There is an association between chronic tinnitus and depressive symptoms in rock musicians, but our results are ambiguous. Although rock musicians have a chronic exposure to noise, noise-induced hearing loss is not the sole causative agent for the development of tinnitus.
Mean age at death of 168 legendary jazz musicians and 100 renowned classical musicians were compared to examine whether psychosocial stressors such as severe substance abuse, haphazard working conditions, lack of acceptance of jazz as an art form in the United States, marital and family discord, and a vagabond life style may have contributed to shortened life spans for the jazz musicians. Analysis indicated that the jazz musicians died at an earlier age (57.2 yr.) than the classical musicians (73.3 yr.).

The core cognitive difficulty in developmental dyslexia involves phonological processing, but adults and children with dyslexia also have sensory impairments. Impairments in basic auditory processing show particular links with phonological impairments, and recent studies with dyslexic children across languages reveal a relationship between auditory temporal processing and sensitivity to rhythmic timing and speech rhythm. As rhythm is explicit in music, musical training might have a beneficial effect on the auditory perception of acoustic cues to rhythm in dyslexia. Here we took advantage of the presence of musicians with and without dyslexia in musical conservatoires, comparing their auditory temporal processing abilities with those of dyslexic non-musicians matched for cognitive ability. Musicians with dyslexia showed equivalent auditory sensitivity to musicians without dyslexia and also showed equivalent rhythm perception. The data support the view that extensive rhythmic experience initiated during childhood (here in the form of music training) can affect basic auditory processing skills which are found to be deficient in individuals with dyslexia.

Musicians tend to strive for flawless performance and perfection, avoiding errors at all costs. Dealing with errors while practicing or performing is often frustrating and can lead to anger and despair, which can explain musicians' generally negative attitude toward errors and the tendency to aim for flawless learning in instrumental music education. But even the best performances are rarely error-free, and research in general pedagogy and psychology has shown that errors provide useful information for the learning process. Research in instrumental pedagogy is still neglecting error issues; the benefits of risk management (before the error) and error management (during and after the error) are still underestimated. It follows that dealing with errors is a key aspect of music practice at home, teaching, and performance in public. And yet, to be innovative, or to make their performance extraordinary, musicians need to risk errors. Currently, most music students only acquire the ability to manage errors implicitly - or not at all. A more constructive, creative, and differentiated culture of errors would balance error tolerance and risk-taking against error prevention in ways that enhance music practice and music performance. The teaching environment should lay the foundation for the development of such an approach. In this contribution, we survey recent research in aviation, medicine, economics, psychology, and interdisciplinary decision theory that has demonstrated that specific error-management training can promote metacognitive skills that lead to better adaptive transfer and better performance skills. We summarize how this research can be applied to music, and survey-relevant research that is specifically tailored to the needs of musicians, including generic guidelines for risk and error management in music teaching and performance. On this basis, we develop a conceptual framework for risk management that can provide orientation for further music education and

Background Several studies have found that musicians perform better than nonmusicians in memory tasks, but this is not always the case, and the strength of this apparent advantage is unknown. Here, we conducted a meta-analysis with the aim of clarifying whether musicians perform better than nonmusicians in memory tasks. Methods Education Source; PEP (WEB)—Psychoanalytic Electronic Publishing; Psychology and Behavioral Science (EBSCO); PsycINFO (Ovid); PubMed; ScienceDirect—AllBooks Content (Elsevier API); SCOPUS (Elsevier API); SocINDEX with Full Text (EBSCO) and Google Scholar were searched for eligible studies. The selected studies involved two groups of participants: young adult musicians and nonmusicians. All the studies included memory tasks (loading long-term, short-term or working memory) that contained tonal, verbal or visuospatial stimuli. Three meta-analyses were run separately for long-term memory, short-term memory and working memory. Results We collected 29 studies, including 53 memory tasks. The results showed that musicians performed better than nonmusicians in terms of long-term memory, g = .29, 95% CI (.08–.51), short-term memory, g = .57, 95% CI (.41–.73), and working memory, g = .56, 95% CI (.33–.80). To further explore the data, we included a moderator (the type of stimulus presented, i.e., tonal, verbal or visuospatial), which was found to influence the effect size for short-term and working memory, but not for long-term memory. In terms of short-term and working memory, the musicians’ advantage was large with tonal stimuli, moderate with verbal stimuli, and small or null with visuospatial stimuli. Conclusions The three meta-analyses revealed a small effect size for long-term memory, and a medium effect size for short-term and working memory, suggesting that musicians perform better than nonmusicians in memory tasks. Moreover, the effect of the moderator suggested that, the type of stimuli influences this advantage. PMID:29049416

To test the "27 club" hypothesis that famous musicians are at an increased risk of death at age 27. Design Cohort study using survival analysis with age as a time dependent exposure. Comparison was primarily made within musicians, and secondarily relative to the general UK population. The popular music scene from a UK perspective. Musicians (solo artists and band members) who had a number one album in the UK between 1956 and 2007 (n = 1046 musicians, with 71 deaths, 7%). Risk of death by age of musician, accounting for time dependent study entry and the number of musicians at risk. Risk was estimated using a flexible spline which would allow a bump at age 27 to appear. We identified three deaths at age 27 amongst 522 musicians at risk, giving a rate of 0.57 deaths per 100 musician years. Similar death rates were observed at ages 25 (rate = 0.56) and 32 (0.54). There was no peak in risk around age 27, but the risk of death for famous musicians throughout their 20s and 30s was two to three times higher than the general UK population. The 27 club is unlikely to be a real phenomenon. Fame may increase the risk of death among musicians, but this risk is not limited to age 27.

When compared with individuals without explicit training in music, adult musicians have facilitated neural functions in several modalities. They also display structural changes in various brain areas, these changes corresponding to the intensity and duration of their musical training. Previous studies have focused on investigating musicians with training in Western classical music. However, musicians involved in different musical genres may display highly differentiated auditory profiles according to the demands set by their genre, i.e., varying importance of different musical sound features. This hypothesis was tested in a novel melody paradigm including deviants in tuning, timbre, rhythm, melody transpositions, and melody contour. Using this paradigm while the participants were watching a silent video and instructed to ignore the sounds, we compared classical, jazz, and rock musicians' and non-musicians' accuracy of neural encoding of the melody. In all groups of participants, all deviants elicited an MMN response, which is a cortical index of deviance discrimination. The strength of the MMN and the subsequent attentional P3a responses reflected the importance of various sound features in each music genre: these automatic brain responses were selectively enhanced to deviants in tuning (classical musicians), timing (classical and jazz musicians), transposition (jazz musicians), and melody contour (jazz and rock musicians). Taken together, these results indicate that musicians with different training history have highly specialized cortical reactivity to sounds which violate the neural template for melody content.

Musical expertise is visible both in the morphology and functionality of the brain. Recent research indicates that functional integration between multi-sensory, somato-motor, default-mode (DMN), and salience (SN) networks of the brain differentiates musicians from non-musicians during resting state. Here, we aimed at determining whether brain networks differentially exchange information in musicians as opposed to non-musicians during naturalistic music listening. Whole-brain graph-theory analyses were performed on participants' fMRI responses. Group-level differences revealed that musicians' primary hubs comprised cerebral and cerebellar sensorimotor regions whereas non-musicians' dominant hubs encompassed DMN-related regions. Community structure analyses of the key hubs revealed greater integration of motor and somatosensory homunculi representing the upper limbs and torso in musicians. Furthermore, musicians who started training at an earlier age exhibited greater centrality in the auditory cortex, and areas related to top-down processes, attention, emotion, somatosensory processing, and non-verbal processing of speech. We here reveal how brain networks organize themselves in a naturalistic music listening situation wherein musicians automatically engage neural networks that are action-based while non-musicians use those that are perception-based to process an incoming auditory stream.

Musicians' skills in auditory processing depend highly on instrument, performance practice, and on level of expertise. Yet, it is not known though whether the style/genre of music might shape auditory processing in the brains of musicians. Here, we aimed at tackling the role of musical style/genre on modulating neural and behavioral responses to changes in musical features. Using a novel, fast and musical sounding multi-feature paradigm, we measured the mismatch negativity (MMN), a pre-attentive brain response, to six types of musical feature change in musicians playing three distinct styles of music (classical, jazz, rock/pop) and in non-musicians. Jazz and classical musicians scored higher in the musical aptitude test than band musicians and non-musicians, especially with regards to tonal abilities. These results were extended by the MMN findings: jazz musicians had larger MMN-amplitude than all other experimental groups across the six different sound features, indicating a greater overall sensitivity to auditory outliers. In particular, we found enhanced processing of pith and sliding up to pitches in jazz musicians only. Furthermore, we observed a more frontal MMN to pitch and location compared to the other deviants in jazz musicians and left lateralization of the MMN to timbre in classical musicians. These findings indicate that the characteristics of the style/genre of music played by musicians influence their perceptual skills and the brain processing of sound features embedded in a musical context. Musicians' brain is hence shaped by the type of training, musical style/genre, and listening experiences. Copyright © 2012 Elsevier Ltd. All rights reserved.

The pedagogical modelling of everyday classroom practice is an interesting kind of evidence, both for educational research and teachers' own professional development. This paper explores the usage of wearable sensors and machine learning techniques to automatically extract orchestration graphs (teaching activities and their social plane over time), on a dataset of 12 classroom sessions enacted by two different teachers in different classroom settings. The dataset included mobile eye-tracking as well as audiovisual and accelerometry data from sensors worn by the teacher. We evaluated both time-independent and time-aware models, achieving median F1 scores of about 0.7-0.8 on leave-one-session-out k-fold cross-validation. Although these results show the feasibility of this approach, they also highlight the need for larger datasets, recorded in a wider variety of classroom settings, to provide automated tagging of classroom practice that can be used in everyday practice across multiple teachers.

College musicians encounter health risks not dissimilar to those of professional musicians. Fifteen collegiate instrumental musicians participated in the intervention program of yogic-breathing and muscle-strengthening and flexibility exercises for 8 weeks. Pre- and post-intervention data from the Health-Pain-Injury Inventory (HPI) and the Physical & Musical-Performance Efficacy Assessment Survey (PME) were analyzed for the effects of the program on the musicians' physical and musical-performance efficacy. HPI results showed that the majority of our sample had healthy lifestyles and minimal pain and injuries but irregular eating and exercise habits. The pre-intervention PME data showed a high level of musical efficacy (i.e., awareness of music technique, tone, and flow) but a low-level of physical efficacy (i.e., awareness of posture, tension, and movement flexibility). Post-intervention data showed that the program improved physical efficacy by increased awareness of posture and tension. In 2 volunteer musicians, kinematics motion analysis was conducted for exploratory purposes. Our cellist played the scale using a larger range of motion (ROM) in right shoulder flexion and abduction and slightly increased rotation while keeping decreased right elbow ROM after the intervention program. The flutist shifted the body weight from one foot to the other more in the second playing post-intervention. These changes can be attributed to the increased physical efficacy that allowed freedom to express musicality. Findings from these case scenarios provide empirically based hypotheses for further study. We share our experience so that others may use our model and instruments to develop studies with larger samples.

In the present study we investigated the capacity of the memory store underlying the mismatch negativity (MMN) response in musicians and nonmusicians for complex tone patterns. While previous studies have focused either on the kind of information that can be encoded or on the decay of the memory trace over time, we studied capacity in terms of the length of tone sequences, i.e., the number of individual tones that can be fully encoded and maintained. By means of magnetoencephalography (MEG) we recorded MMN responses to deviant tones that could occur at any position of standard tone patterns composed of four, six or eight tones during passive, distracted listening. Whereas there was a reliable MMN response to deviant tones in the four-tone pattern in both musicians and nonmusicians, only some individuals showed MMN responses to the longer patterns. This finding of a reliable capacity of the short-term auditory store underlying the MMN response is in line with estimates of a three to five item capacity of the short-term memory trace from behavioural studies, although pitch and contour complexity covaried with sequence length, which might have led to an understatement of the reported capacity. Whereas there was a tendency for an enhancement of the pattern MMN in musicians compared to nonmusicians, a strong advantage for musicians could be shown in an accompanying behavioural task of detecting the deviants while attending to the stimuli for all pattern lengths, indicating that long-term musical training differentially affects the memory capacity of auditory short-term memory for complex tone patterns with and without attention. Also, a left-hemispheric lateralization of MMN responses in the six-tone pattern suggests that additional networks that help structuring the patterns in the temporal domain might be recruited for demanding auditory processing in the pitch domain.

Musician earplugs are marketed and recommended for use in music settings but no studies have evaluated these products with musicians. This study evaluated the influences of earplugs on college students' perception and abilities to communicate in a musical environment, attitudes of earplugs, comfort over time, and the influence of earplugs on ability to play music. College students (N = 323) were provided with earplugs for use during and following an experimental condition designed to mimic a night club. Results underline the challenges of earplugs in environments that are both loud and require verbal interaction. Responses to comfort questions were variable and suggest a multi-factorial set of influences that may include intrinsic variables. Despite these limitations, subjects in this study generally liked the earplugs and believed that they are valuable. However, the earplugs were not viewed favorably by musicians willing to use the earplugs while playing music. This study supports the view that earplugs are subject to many problems and should be considered as a last resort.

Syphilis is a sexually transmitted, systemic disease caused by the spirochete bacterium Treponema pallidum. The most common mechanism of transmission is sexual intercourse. Although there are several hypotheses, the exact origin of the disease remains unknown. Newly published evidence suggests that the hypothesis supporting the theory of the American origin of the disease is the valid one. Among 1500 analyzed pathographies of composers and musicians, data on ten Anglo-American composers and jazz musicians having suffered from neurosyphilis (tertiary stage of the disease) were extracted for this report. In this group of Anglo-American composers and musicians, most of them died from progressive paralysis while still in the creative phase of life. Additionally, diagnoses of eleven other famous neurosyphilitic composers, as well as basic biographic data on ten less known composers that died from neurosyphilis-progressive paralysis are also briefly mentioned. In conclusion, neurosyphilis can cause serious neurological damage, as well as permanent disability or death, preventing further work and skill improvement.
Full Text Available In Greece, the monophonic chant of the Orthodox church and its neumatic notation have been transmitted as a popular tradition up to the first decades of the 20th century. The transformation of Greek musical tradition to a Western type of urban culture and the introduction of harmony, staff notation and western instruments and performance practices in the country began in the 19th century. Italian musicians played a central role in that process. A large number of them lived and worked on the Ionian Islands. Those Italian musicians have left a considerable number of transcriptions and original compositions. Quite a different cultural background existed in Athens. Education was in most cases connected to the church - the institution that during the four centuries of Turkish occupation kept Greeks united and nationally conscious. The neumatic notation was used for all music sung by the people, music of both western and eastern origin. The assimilation of staff notation and harmony was accelerated in the last quarter of the 19th century. At the beginning of the 20th century in Athens a violent cultural clash was provoked by the reformers of music education all of them belonging to German culture. The clash ended with the displacement of the Italian and Greek musicians from the Ionian Islands working at the time in Athens, and the defamation of their fundamental work in music education.

Cortical auditory evoked potentials of instrumental musicians suggest that music expertise modifies pitch processing, yet less is known about vocal musicians. Mismatch negativity (MMN) to pitch deviances and difference limen for frequency (DLF) were examined among 61 young adult women, including 20 vocalists, 21 instrumentalists, and 20 nonmusicians. Stimuli were harmonic tone complexes from the mid-female vocal range (C4-G4). MMN was elicited by multideviant paradigm. DLF was obtained by an adaptive psychophysical paradigm. Musicians detected pitch changes earlier and DLFs were 50% smaller than nonmusicians. Both vocal and instrumental musicians possess superior sensory-memory representations for acoustic parameters. Vocal musicians with instrumental training appear to have an auditory neural advantage over instrumental or vocal only musicians. An incidental finding reveals P3a as a sensitive index of music expertise.

Musicians report a considerably higher prevalence of insomnia symptoms compared to community samples in the general workforce. The aim of this study was to investigate the association between insomnia and health, work-related, and lifestyle factors among musicians. A total of 645 full-time musicians completed a questionnaire measuring insomnia symptoms: personality, psychosocial factors (perceived job demands, job control, effort-reward imbalance, and general social support), and lifestyle (s...

The increased incidence of health challenges with aging means that nurses are increasingly caring for older adults, often in hospital settings. Research about the complexity of nursing practice with this population remains limited. To seek an explanation of nursing practice with hospitalised older adults. Design. A grounded theory study guided by symbolic interactionism was used to explore nursing practice with hospitalised older adults from a nursing perspective. Glaserian grounded theory methods were used to develop a mid-range theory after analysis of 375 hours of participant observation, 35 interviews with 24 participants and review of selected documents. The theory of orchestrating care was developed to explain how nurses are continuously trying to manage their work environments by understanding the status of the patients, their unit, mobilising the assistance of others and stretching available resources to resolve their problem of providing their older patients with what they perceived as 'good care' while sustaining themselves as 'good' nurses. They described their practice environments as hard and under-resourced. Orchestrating care is comprised of two subprocesses: building synergy and minimising strain. These two processes both facilitated and constrained each other and nurses' abilities to orchestrate care. Although system issues presented serious constraints to nursing practice, the ways in which nurses were making meaning of their work environment both aided them in managing their challenges and constrained their agency. Nurses need to be encouraged to share their important perspective about older adult care. Administrators have a role to play in giving nurses voice in workplace committees and in forums. Further research is needed to better understand how multidisciplinary teams influence care of hospitalized older adults. © 2014 John Wiley & Sons Ltd.

Full Text Available Inflammation, altered immune cell phenotype, and functions are key features shared by diverse chronic diseases, including cardiovascular, neurodegenerative diseases, diabetes, metabolic syndrome, and cancer. Natural killer cells are innate lymphoid cells primarily involved in the immune system response to non-self-components but their plasticity is largely influenced by the pathological microenvironment. Altered NK phenotype and function have been reported in several pathological conditions, basically related to impaired or enhanced toxicity. Here we reviewed and discussed the role of NKs in selected, different, and “distant” chronic diseases, cancer, diabetes, periodontitis, and atherosclerosis, placing NK cells as crucial orchestrator of these pathologic conditions.
Full Text Available Musicians tend to strive for flawless performance and perfection, avoiding errors at all costs. Dealing with errors while practicing or performing is often frustrating and can lead to anger and despair, which can explain musicians’ generally negative attitude toward errors and the tendency to aim for errorless learning in instrumental music education. But even the best performances are rarely error-free, and research in general pedagogy and psychology has shown that errors provide useful information for the learning process. Research in instrumental pedagogy is still neglecting error issues; the benefits of risk management (before the error and error management (during and after the error are still underestimated. It follows that dealing with errors is a key aspect of music practice at home, teaching, and performance in public. And yet, to be innovative, or to make their performance extraordinary, musicians need to risk errors. Currently, most music students only acquire the ability to manage errors implicitly - or not at all. A more constructive, creative and differentiated culture of errors would balance error tolerance and risk-taking against error prevention in ways that enhance music practice and music performance. The teaching environment should lay the foundation for the development of these abilities. In this contribution, we survey recent research in aviation, medicine, economics, psychology, and interdisciplinary decision theory that has demonstrated that specific error-management training can promote metacognitive skills that lead to better adaptive transfer and better performance skills. We summarize how this research can be applied to music, and survey relevant research that is specifically tailored to the needs of musicians, including generic guidelines for risk and error management in music teaching and performance. On this basis, we develop a conceptual framework for risk management that can provide orientation for further

The purpose of this study was to determine daily noise doses and 8-hour time weighted averages for rock band musicians, crew members, and spectators during a typical rehearsal and performance using both Occupational Safety and Health Administration (OSHA) and National Institute of Occupational Safety and Health (NIOSH) measurement criteria. Personal noise dosimetry was completed on five members of a rock band during one 2-hr rehearsal and one 4-hr performance. Time-weighted averages (TWA) and daily dose values were calculated using both OSHA and NIOSH criteria and compared to industry guidelines for enrollment in hearing conservation programs and the use of hearing protection devices. TWA values ranged from 84.3 to 90.4 dBA (OSHA) and from 90.0 to 96.4 dBA (NIOSH) during the rehearsal. The same values ranged from 91.0 to 99.7 dBA (OSHA) and 94.0 to 102.8 dBA (NIOSH) for the performance. During the rehearsal, daily noise doses ranged from 45.54% to 106.7% (OSHA) and from 317.74% to 1396.07% (NIOSH). During the performance, doses ranged from 114.66% to 382.49% (OSHA) and from 793.31% to 5970.15% (NIOSH). The musicians in this study were exposed to dangerously high levels of noise and should be enrolled in a hearing conservation programs. Hearing protection devices should be worn, especially during performances. The OSHA measurement criteria yielded values significantly more conservative than those produced by NIOSH criteria. Audiologists should counsel musician-patients about the hazards of excessive noise (music) exposure and how to protect their hearing.

Full Text Available When compared with individuals without explicit training in music, adult musicians have facilitated neural functions in several modalities. They also display structural changes in various brain areas, these changes corresponding to the intensity and duration of their musical training. Previous studies have focused on investigating musicians with training in Western classical music. However, musicians involved in different musical genres may display highly differentiated auditory profiles according to the demands set by their genre, i.e. varying importance of different musical sound features. This hypothesis was tested in a novel melody paradigm including deviants in tuning, timbre, rhythm, melody transpositions, and melody contour. Using this paradigm while the participants were watching a silent video and instructed to ignore the sounds, we compared classical, jazz, and rock musicians’ and non-musicians’ accuracy of neural encoding of the melody. In all groups of participants, all deviants elicited an MMN response, which is a cortical index of deviance discrimination. The strength of the MMN and the subsequent attentional P3a responses reflected the importance of various sound features in each music genre: these automatic brain responses were selectively enhanced to deviants in tuning (classical musicians, timing (classical and jazz musicians, transposition (jazz musicians, and melody contour (jazz and rock musicians. Taken together, these results indicate that musicians with different training history have highly specialized cortical reactivity to sounds which violate the neural template for melody content.

Musicians are at risk of hearing loss from sound exposure, and earplugs form part of many musicians' hearing conservation practices. Although musicians typically report a range of difficulties when wearing earplugs, there are many who have managed to successfully incorporate earplugs into their practice of music. The study aim was to provide a detailed account of earplug usage from the perspective of the musician, including motivating factors, practical strategies, and attitudes. In-depth interviews with 23 musicians were transcribed and content analysis was performed. Responses were coded and classified into three main themes: advantages, disadvantages, and usage patterns and strategies, together with an overlapping fourth theme, youth perspectives. Several positive aspects of wearing earplugs were identified, including long-term hearing protection and reduced levels of fatigue and pain. Musicians reported that earplugs present few problems for communication, improve sound clarity in ensembles, are discreet, and are easy to handle. However, earplugs also present challenges, including an overall dullness of sound, reduced immediacy, and an impaired ability to judge balance and intonation due to the occlusion effect, all of which influence usage habits and patterns. The experiences of the younger musicians and long-term users of earplugs indicate that practice, persistence, and a flexible approach are required for successful earplug usage. In time, there may be greater acceptance of earplugs, particularly amongst a new generation of musicians, some of whom regard the earplugs as a performance enhancement tool as well as a protective device.

Musicians' perceptual advantage in the acoustic domain is well established. Recent studies show that musicians' verbal working memory is also superior. Additionally, some studies report that musicians' visuospatial skills are enhanced although others failed to find this enhancement. We now examined whether musicians' spatial vision is superior, and if so, whether this superiority reflects refined visual skills or a general superiority of working memory. We examined spatial frequency discrimination among musicians and nonmusician university students using two presentation conditions: simultaneous (spatial forced choice) and sequential (temporal forced choice). Musicians' performance was similar to that of nonmusicians in the simultaneous condition. However, their performance in the sequential condition was superior, suggesting an advantage only when stimuli need to be retained, i.e., working memory. Moreover, the two groups showed a different pattern of correlations: Musicians' visual thresholds were correlated, and neither was correlated with their verbal memory. By contrast, among nonmusicians, the visual thresholds were not correlated, but sequential thresholds were correlated with verbal memory scores, suggesting that a general working memory component limits their performance in this condition. We propose that musicians' superiority in spatial frequency discrimination reflects an advantage in a domain-general aspect of working memory rather than a general enhancement in spatial-visual skills. © 2014 ARVO.

Above-average levels of psychopathology have been demonstrated convincingly in groups of outstanding individuals working in the arts. Currently, jazz musicians have not been studied in this regard. To investigate any evidence of psychopathology in a group of eminent jazz musicians. Biographical material relating to 40 eminent American modern jazz musicians was reviewed and an attempt was made to formulate diagnoses using DSM-IV. Evidence was provided of levels of psychopathology in the sample of jazz musicians similar to those found in other previously investigated creative groups, with the exception of substance related problems. An interesting connection between creativity and sensation-seeking was highlighted. The link between psychopathology and creativity in the arts was given further weight. Future studies of jazz musicians using larger samples and making comparison with groups from different eras of music would give greater clarification to this area.

The growing computing power on leadership HPC systems is often accompanied by ever-escalating failure rates. Checkpointing is a common defensive mechanism used by scientific applications for failure recovery. However, directly writing the large and bursty checkpointing dataset to parallel filesystem can incur significant I/O contention on storage servers. Such contention in turn degrades the raw bandwidth utilization of storage servers and prolongs the average job I/O time of concurrent applications. Recently burst buffer has been proposed as an intermediate layer to absorb the bursty I/O traffic from compute nodes to storage backend. But an I/O orchestration mechanism is still desired to efficiently move checkpointing data from bursty buffers to storage backend. In this paper, we propose a burst buffer based I/O orchestration framework, named TRIO, to intercept and reshape the bursty writes for better sequential write traffic to storage severs. Meanwhile, TRIO coordinates the flushing orders among concurrent burst buffers to alleviate the contention on storage server bandwidth. Our experimental results reveal that TRIO can deliver 30.5% higher bandwidth and reduce the average job I/O time by 37% on average for data-intensive applications in various checkpointing scenarios.
Full Text Available Music is inherently an auditory art form, rooted in sound, and generally analyzed in terms of its acoustic properties. However, as the process of hearing is affected by seeing, visual information does in fact play an important role in the musical experience. Vision influences many aspects of music – from evaluations of performance quality and audience interest to the perception of loudness, timbre, and note duration. Moreover, it can be used to achieve musical goals that are in fact acoustically impossible. As such, understanding the benefits of embracing (and the costs of ignoring vision’s role is essential for all musicians. Furthermore, since music represents a pervasive and ubiquitous human practice, this topic serves as an ideal case study for understanding how auditory and visual information are integrated. Given that some musically-based studies have challenged and even contributed to updating psychological theories of sensory integration, this topic represents a rich area of research, relevant to musicians and psychologists alike.

Music performance anxiety (MPA) is an issue frequently experienced by musicians. It occurs not only in experienced musicians but also in children and adolescents. Furthermore, most research on MPA has been done with musicians who specialized in classical music. This study investigated the development of MPA across the ages in young musicians focusing on the classical and popular genres. In a cross-sectional survey, 239 students at German music schools, aged between 7 and 20 yrs, were asked about their perceived MPA and musical background. The data were analyzed according to musical genre and age. Multiple regression analyses were performed to investigate the influences of musical experiences on MPA. The analyses yielded high levels of MPA for classical musicians between 7 and 16 yrs, which was reduced in older students; for popular musicians, low MPA was seen in the younger (7-11 yrs) and high MPA in the older (16+ yrs) musicians. MPA was influenced by gender and the number of performances in the classical music group and only by gender and age in the popular music group. The results showed clear different trends for the development of MPA between musical genres that should be taken into account for educational aspects in musical training.

Neurological histories of great musicians allow for a unique perspective on music physiology. Bedrich Smetana's autobiographical string quartet ends with the musical equivalent of tinnitus in the fourth movement, rendering the youthful and passionate themes of earlier movements moot as the piece ends depicting his ultimately fatal disease, neurosyphilis. Dmitri Shostakovich survived the censorship of Joseph Stalin's apparatchiks but suffered a prolonged form of paralysis attributable to slowly progressive motor neuron disease, although the viola sonata he wrote on his deathbed has become standard repertoire. Glenn Gould was a hypochondriacal pianist with obsessive-compulsive disorder and suspected Asperger syndrome. Vissarion Shebalin and (Ira) Randall Thompson had strokes followed by aphasia without amusia. Domenico Scarlatti provides an example of how even great composers must alter their technical expectations depending upon the skills and body habitus of their chief patrons. The focal dystonia afflicting Leon Fleisher and Gary Graffman catalyzed the discipline of performing arts medicine.

Full Text Available The Serbian ethnomusicologist and music pedagogue Miodrag A. Vasiljević corresponded with colleagues from neighboring Bulgaria between 1934 and 1962. This exchange of letters went through three phases. The first phase was linked with his stay in Skopje until the breakout of World War II; during the second phase - in the course of the 1940's - he was active in the Department for Folk Music at Radio Belgrade and he founded his method of music teaching on traditional Serbian music; in the third phase (the 1950's and beginning of 1960's Vasiljević aimed at a closer cooperation with Bulgarian musicians. All the phases are characterized by his pronounced interest in the folk music heritage of Balkan peoples. At the beginning that interest was focused on popularizing art music that was based on folk music. Later, he enthusiastically carried out his reforms of music teaching in Serbia, as well as improvements of methods in Serbian ethnomusicology.

In music, multiple musical objects often overlap in time. Western polyphonic music contains multiple simultaneous melodic lines (referred to as "voices") of equal importance. Previous electrophysiological studies have shown that pitch changes in a single melody are automatically encoded in memory traces, as indexed by mismatch negativity (MMN) and its magnetic counterpart (MMNm), and that this encoding process is enhanced by musical experience. In the present study, we examined whether two simultaneous melodies in polyphonic music are represented as separate entities in the auditory memory trace. Musicians and untrained controls were tested in both magnetoencephalogram and behavioral sessions. Polyphonic stimuli were created by combining two melodies (A and B), each consisting of the same five notes but in a different order. Melody A was in the high voice and Melody B in the low voice in one condition, and this was reversed in the other condition. On 50% of trials, a deviant final (5th) note was played either in the high or in the low voice, and it either went outside the key of the melody or remained within the key. These four deviations occurred with equal probability of 12.5% each. Clear MMNm was obtained for most changes in both groups, despite the 50% deviance level, with a larger amplitude in musicians than in controls. The response pattern was consistent across groups, with larger MMNm for deviants in the high voice than in the low voice, and larger MMNm for in-key than out-of-key changes, despite better behavioral performance for out-of-key changes. The results suggest that melodic information in each voice in polyphonic music is encoded in the sensory memory trace, that the higher voice is more salient than the lower, and that tonality may be processed primarily at cognitive stages subsequent to MMN generation.

Full Text Available The musicians’ job market in Brazil is heterogeneous in various senses. It is characterized by informality and job insecurity, in addition to being segmented by gender, both with respect to musical forms and to social relations between the sexes and the construction of correlative social representations. The purpose of this article is to analyze the work of musicians in Brazil, highlighting the recent occupational displacement that affects professional identities and the conciliation practices and domestic arrangements in households where musicians live. The methodology used was a quali-quantitative approach and the triangulation of sources: government databases, and surveys using Internet profiles selected through web scraping and interviews. The exploratory factor analysis based on variables related to domestic work and musical work identified five factors: traditional delegation arrangement, competitive musical work, societal conciliation arrangement, internal conciliation, and community conciliation. Findings showed that traditional delegation in the case of domestic work is not only explained by the relation between reproductive and productive work, with the traditional devaluation or subalternization of the former, but also by a gender construction that ends up assigning women–who are a minority in terms of employment–to teaching activities in the field of higher education and to their placement in stable formations, generally with higher performance and less flexible forms of hiring. Conciliation strategies involving musical work reflect the distinction, in the context of specific cultural and social characteristics, among orienting oneself through the assistance available in the services market, the State, or family arrangements, seen as ideal types, since these practices overlap. However, on the basis of the abovementioned factors, the current outlook reveals an imbalance with respect to the experience and
Full Text Available Smartphones have greater computing power than ever before, providing convenient applications to improve our lives. In general, people find it difficult to locate suitable applications and implementing new applications often requires professional skills. In this paper, we propose a new service platform that facilitates the implementation of new applications by composing prebuilt components that provide the context information of mobile devices such as location and contacts. Our platform introduces an innovative concept named context collaboration, in which smartphones exchange context information with each other, which in turn is used to deduct useful inferences. The concept is realized by instant orchestration, which assembles some components and implements a composite component. The interactive communication interface helps a mobile device to communicate with other devices using open APIs, such as SOAP and HTTP (REST. The platform also works in heterogeneous environments, for example, between Android and iOS operating systems. Throughout the platform, mobile devices can act as smart M2M machines with context awareness, enabling intelligent tasks on behalf of users. Our platform will open up a new and innovative pathway for both enhanced mobile context awareness and M2M, which is expected to be a fundamental feature of the next generation of mobile devices.

Full Text Available Structure and function of the human brain are affected by training in both linguistic and musical domains. Individuals with intensive vocal musical training provide a useful model for investigating neural adaptations of learning in the vocal-motor domain and can be compared with learning in a more general musical domain. Here we confirm general differences in macrostructure (tract volume and microstructure (fractional anisotropy (FA of the arcuate fasciculus (AF, a prominent white-matter tract connecting temporal and frontal brain regions, between singers, instrumentalists, and non-musicians. Both groups of musicians differed from non-musicians in having larger tract volume and higher FA values of the right and left AF. The AF was then subdivided in a dorsal (superior branch connecting the superior temporal gyrus and the inferior frontal gyrus (STG<–>IFG, and ventral (inferior branch connecting the middle temporal gyrus and the inferior frontal gyrus (MTG<–>IFG. Relative to instrumental musicians, singers had a larger tract volume but lower FA values in the left dorsal AF (STG<–>IFG, and a similar trend in the left ventral AF (MTG<–>IFG. This between-group comparison controls for the general effects of musical training, although FA was still higher in singers compared to non-musicians. Both musician groups had higher tract volumes in the right dorsal and ventral tracts compared to non-musicians, but did not show a significant difference between each other. Furthermore, in the singers’ group, FA in the left dorsal branch of the AF was inversely correlated with the number of years of participants’ vocal training. Our findings suggest that long-term vocal-motor training might lead to an increase in volume and microstructural complexity of specific white matter tracts connecting regions that are fundamental to sound perception, production, and its feedforward and feedback control which can be differentiated from a more general musician

Individuals with intensive vocal musical training provide a useful model for investigating neural adaptations of learning in the vocal-motor domain and can be compared with learning in a more general musical domain.

The present study used magnetoencephalography (MEG) to identify the neural correlates of audiovisual statistical learning, while disentangling the differential contributions of uni- and multi-modal statistical mismatch responses in humans. The applied paradigm was based on a combination of a statistical learning paradigm and a multisensory oddball one, combining an audiovisual, an auditory and a visual stimulation stream, along with the corresponding deviances. Plasticity effects due to musical expertise were investigated by comparing the behavioral and MEG responses of musicians to non-musicians. The behavioral results indicated that the learning was successful for both musicians and non-musicians. The unimodal MEG responses are consistent with previous studies, revealing the contribution of Heschl's gyrus for the identification of auditory statistical mismatches and the contribution of medial temporal and visual association areas for the visual modality. The cortical network underlying audiovisual statistical learning was found to be partly common and partly distinct from the corresponding unimodal networks, comprising right temporal and left inferior frontal sources. Musicians showed enhanced activation in superior temporal and superior frontal gyrus. Connectivity and information processing flow amongst the sources comprising the cortical network of audiovisual statistical learning, as estimated by transfer entropy, was reorganized in musicians, indicating enhanced top-down processing. This neuroplastic effect showed a cross-modal stability between the auditory and audiovisual modalities. Copyright © 2018 Elsevier Inc. All rights reserved.

Playing-related musculoskeletal disorders (PRMDs) are common in musicians and interfere with the ability to play an instrument at the accustomed level. There is limited research into injuries affecting folk musicians. To explore the Irish traditional musicians' experience of PRMDs. Focus group interviews were conducted in 2011 and 2012, in two venues in Ireland. Data were recorded and transcribed verbatim. Data collection ended when no new findings emerged from the analysis of interviews. The inclusion criteria were: males or females aged 18 and above, and who taught or played Irish traditional music on any instrument. The data were analysed using the interpretative phenomenological method. All participants (n=22) believed there was a link between playing music and musculoskeletal problems. The main body areas affected were the back, shoulders, arms and hands. The main theme that emerged was: 'PRMDs are an integral part of being a traditional musician', and that the musical experience was generally prioritised over the health of the musician. There were sub-themes of 'fear' and 'stresses that contributed to PRMDs'. PRMDs are an occupational hazard for Irish musicians. There is an awareness of PRMDs, but changes (technique, environment) may threaten identity.

In order to analyze environmental dynamics, a major process is the classification of the different phenomena of the site (e.g. ice and snow for a glacier). When using in situ pictures, this classification requires data pre-processing. Not all the pictures need the same sequence of processes depending on the disturbances. Until now, these sequences have been done manually, which restricts the processing of large amount of data. In this paper, we present how to realize a semantic orchestration to automate the sequencing for the analysis. It combines two advantages: solving the problem of the amount of processing, and diversifying the possibilities in the data processing. We define a BPEL description to express the sequences. This BPEL uses some web services to run the data processing. Each web service is semantically annotated using an ontology of image processing. The dynamic modification of the BPEL is done using SPARQL queries on these annotated web services.

Orchestrated structure evolution (OSE) is a scalable manufacturing method that combines the advantages of top-down (tool-directed) and bottom-up (self-propagating) approaches. The method consists of a seed patterning step that defines where material nucleates, followed by a growth step that merges seeded islands into the final patterned thin film. We develop a model to predict the completed pattern based on a computationally efficient approximate Green's function solution of the diffusion equation plus a Voronoi diagram based approach that defines the final grain boundary structure. Experimental results rely on electron beam lithography to pattern the seeds, followed by the mass transfer limited growth of copper via electrodeposition. The seed growth model is compared with experimental results to quantify nearest neighbor seed-to-seed interactions as well as how seeds interact with the pattern boundary to impact the local growth rate. Seed-to-seed and seed-to-pattern interactions are shown to result in overgrowth of seeds on edges and corners of the shape, where seeds have fewer neighbors. We explore how local changes to the seed location can be used to improve the patterning quality without increasing the manufacturing cost. OSE is shown to enable a unique set of trade-offs between the cost, time, and quality of thin film patterning.

Amidation is the fourth major category of post-translational modifications, which plays an important role in physiological and pathological processes. Identifying amidation sites can help us understanding the amidation and recognizing the original reason of many kinds of diseases. But the traditional experimental methods for predicting amidation sites are often time-consuming and expensive. In this study, we propose a computational method for predicting amidation sites by orchestrating amino acid sequence features. Three kinds of feature extraction methods are used to build a feature vector enabling to capture not only the physicochemical properties but also position related information of the amino acids. An extremely randomized trees algorithm is applied to choose the optimal features to remove redundancy and dependence among components of the feature vector by a supervised fashion. Finally the support vector machine classifier is used to label the amidation sites. When tested on an independent data set, it shows that the proposed method performs better than all the previous ones with the prediction accuracy of 0.962 at the Matthew's correlation coefficient of 0.89 and area under curve of 0.964.

We describe the conclusions of a technology and communities survey supported by concurrent and follow-on proof-of-concept prototyping to evaluate feasibility of defining a durable, versatile, reliable, visible software interface to support strategic modularization of test software development. The objective is that test sets and support software with diverse origins, ages, and abilities can be reliably integrated into test configurations that assemble and tear down and reassemble with scalable complexity in order to conduct both parametric tests and monitored trial runs. The resulting approach is based on integration of three recognized technologies that are currently gaining acceptance within the test industry and when combined provide a simple, open and scalable test orchestration architecture that addresses the objectives of the Automation Hooks task. The technologies are automated discovery using multicast DNS Zero Configuration Networking (zeroconf), commanding and data retrieval using resource-oriented Restful Web Services, and XML data transfer formats based on Automatic Test Markup Language (ATML). This open-source standards-based approach provides direct integration with existing commercial off-the-shelf (COTS) analysis software tools.

DNA damage occurs within the chromatin environment, which ultimately participates in regulating DNA damage response (DDR) pathways and repair of the lesion. DNA damage activates a cascade of signaling events that extensively modulates chromatin structure and organization to coordinate DDR factor recruitment to the break and repair, whilst also promoting the maintenance of normal chromatin functions within the damaged region. For example, DDR pathways must avoid conflicts between other DNA-based processes that function within the context of chromatin, including transcription and replication. The molecular mechanisms governing the recognition, target specificity, and recruitment of DDR factors and enzymes to the fundamental repeating unit of chromatin, i.e., the nucleosome, are poorly understood. Here we present our current view of how chromatin recognition by DDR factors is achieved at the level of the nucleosome. Emerging evidence suggests that the nucleosome surface, including the nucleosome acidic patch, promotes the binding and activity of several DNA damage factors on chromatin. Thus, in addition to interactions with damaged DNA and histone modifications, nucleosome recognition by DDR factors plays a key role in orchestrating the requisite chromatin response to maintain both genome and epigenome integrity.

Slow-wave sleep (SWS) facilitates the consolidation of hippocampus-dependent declarative memory. Based on the standard two-stage memory model, we propose that memory consolidation during SWS represents a process of system consolidation which is orchestrated by the neocortical memory. The slow oscillations temporally group neuronal activity into up-states of strongly enhanced neuronal activity and down-states of neuronal silence. In a feed-forward efferent action, this grouping is induced not only in the neocortex but also in other structures relevant to consolidation, namely the thalamus generating 10-15Hz spindles, and the hippocampus generating sharp wave-ripples, with the latter well known to accompany a replay of newly encoded memories taking place in hippocampal circuitries. The feed-forward synchronizing effect of the slow oscillation enables the formation of spindle-ripple events where ripples and accompanying reactivated hippocampal memory information become nested into the single troughs of spindles. Spindle-ripple events thus enable reactivated memory-related hippocampal information to be fed back to neocortical networks in the excitable slow oscillation up-state where they can induce enduring plastic synaptic changes underlying the effective formation of long-term memories.

The aim of this study was to determine the effects of alpha neurofeedback and EMG biofeedback protocols for improvement of musical performance in violinists. The sample consisted of 12 music students (10 violinists and 2 viola players) from the Faculty of Music, Skopje (3 males, mean age of 20 +/- 0 and 9 females, mean age = 20.89 +/- 2.98). Six of them had a low alpha peak frequency (APF) ( 10 Hz). The sample was randomized in two groups. The students from the experimental group participated in 20 sessions of biofeedback (alpha/EMG), combined with music practice, while the students from the control group did only music practice. Average absolute power, interhemispheric coherence in the alpha band, alpha peak frequency (APF), individual alpha band width (IABW), amount of alpha suppression (AAS) and surface forehead integrated EMG power (IEMG), as well as a score on musical performance and inventories measuring anxiety, were assessed. Alpha-EEG/EMG-biofeedback was associated with a significant increase in average alpha power, APF and IABW in all the participants and with decreases in IEMG only in high-APF musicians. The biofeedback training success was positively correlated with the alpha power, IcoH, APF, IABW and baseline level of APF and IABW. Alpha-EEG/EMG biofeedback is capable of increasing voluntary self-regulation and the quality of musical performance. The efficiency of biofeedback training depends on the baseline EEG alpha activity status, in particular the APF.

Full Text Available With over 70 dancers and its own orchestra, The National Ballet of Canada ranks amongst the world′s top dance companies. It performs three seasons annually: fall, winter and summer, plus many shows of Tchaikovsky′s Nutcracker. The 70-strong orchestra plays an average of 360 hours/year including rehearsals and performances. Rehearsals are held at two locations: one in a ballet rehearsal room with little or no absorption, and the other in an acoustically treated location. Performances are held in the Four Seasons Centre for the Performing Arts in Toronto. The present survey was done at the request of the National Ballet, since the musicians complained of excessive sound levels and were concerned about possible hearing losses. The survey was performed using five dosimeters Quest Mod 300 during 10 performances of the ballet Romeo and Juliet by Sergei Prokofiev, deemed as the noisiest in the whole repertoire. Results of the survey indicate that the noise exposure levels from only the orchestra′s activities do not present risk of hearing loss. Exposure due to other musical activities was, however, not included.

Although yoga has been shown to be a viable technique for improving the performance of the mind and body, little attention has been directed to studying the relationship between yoga and the psychological states of flow and mindfulness. Musicians enrolled in a 2-month fellowship program in 2005, 2006 and 2007 were invited to participate in a yoga and meditation program. Fellows not participating in the yoga program were recruited separately as controls. All participants completed baseline and end-program questionnaires evaluating dispositional flow, mindfulness, confusion, and music performance anxiety. Compared to controls, yoga participants reported significant decreases in confusion and increases in dispositional flow. Yoga participants in the 2006 sample also reported significant increases in the mindfulness subscale of awareness. Correlational analyses revealed that increases in participants' dispositional flow and mindfulness were associated with decreases in confusion and music performance anxiety. This study demonstrates the commonalities between positive psychology and yoga, both of which are focused on enhancing human performance and promoting beneficial psychological states. The results suggest that yoga and meditation may enhance the states of flow and mindful awareness, and reduce confusion.

The National Ignition Facility (NIF), currently under construction at the Lawrence Livermore National Laboratory, is a stadium-sized facility containing a 192-beam, 1.8 Megajoule, 500-Terawatt, ultra-violet laser system together with a 10-meter diameter target chamber with room for nearly 100 experimental diagnostics. When completed, NIF will be the world's largest and most energetic laser experimental system, providing an international center to study inertial confinement fusion and physics of matter at extreme densities and pressures. The NIF is operated by the Integrated Computer Control System (ICCS), which is a layered architecture of over 700 lower-level front-end processors attached to nearly 60,000 control points and coordinated by higher-level supervisory subsystems in the main control room. A shot automation framework has been developed and deployed during the past year to orchestrate and automate shots performed at the NIF using the ICCS. The Shot Automation framework is designed to automate 4-8 hour shot sequences, that includes deriving shot goals from an experiment definition, set up of the laser and diagnostics, automatic alignment of laser beams, and a countdown to charge and fire the lasers. These sequences consist of set of preparatory verification shots, leading to amplified system shots followed by post-shot analysis and archiving. The framework provides for a flexible, model-based work-flow execution, driven by scripted automation called macro steps. The shot director software is the orchestrating component of a very flexible automation layer which allows us to define, coordinate and reuse simpler automation sequences. This software provides a restricted set of shot life cycle state transitions to 26 collaboration supervisors that automate 8-laser beams (bundle) and a common set of shared resources. Each collaboration supervisor commands approximately 10 subsystem shot supervisors that perform automated control and status verification
Full Text Available Multimedia conferencing is increasingly becoming a very important and popular application over Internet. Due to the complexity of asynchronous communications and handle large and dynamically concurrent processes for multimedia conferencing, which confront relevant challenge to achieve sufficient correctness guarantees, and supporting the effective verification methods for multimedia conferencing services orchestration is an extremely difficult and challenging problem. In this paper, we firstly present the Business Process Execution Language (BPEL based conferencing service orchestration, and mainly focus on the service net based correction verification approach for multimedia conferencing services orchestration, which can automatically translated the BPEL based service orchestration into a corresponding Petri net model with the Petri Net Markup Language (PNML, and also present the BPEL service net reduction rules and multimedia conferencing service orchestration correction verification algorithms. We perform the correctness analysis and verification using the service net properties as safeness, reachability and deadlocks, and also provide an automated support tool for the formal analysis and soundness verification for the multimedia conferencing services orchestration scenarios. Finally, we give the comparison and evaluations.

Full Text Available Abstract Introduction: The instrumental practice for a long time, the high performance level, the strict technique and the specific shape of each musical instrument can take musicians to overcome their physiological limits, giving a high prevalence of musculoskeletal injuries. Objective: Investigate the prevalence of temporomandibular joint disorder and neck pain in musicians. Methods: Between August and September 2015 were reviewed five databases: LILACS, SciELO, Medline / PubMed, Scopus and Web of Science. The articles were read and evaluated by the criteria of the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE, items, that obtained a percentage above of 50 percent, were considered in the analysis of this work. Results: 15 articles attended the inclusion criteria. Among all musicians the prevalence of TMJ pain ranged from 10 - 81% and the prevalence of neck pain ranged from 29 - 80%. Conclusion: In this study was observed that the musicians showed both, temporomandibular joint disorders and neck pain, watching a high prevalence especially in violinists and the horn players. In the risk factors identified in the literature for the emergence of painful symptoms in musicians, stand out the biomechanical factors involved in maintaining anti-physiologic postures.

Working memory (WM) for auditory information has been thought of as a unitary system, but whether WM for verbal and tonal information relies on the same or different functional neuroarchitectures has remained unknown. This fMRI study examines verbal and tonal WM in both nonmusicians (who are trained in speech, but not in music) and highly trained musicians (who are trained in both domains). The data show that core structures of WM are involved in both tonal and verbal WM (Broca's area, premotor cortex, pre-SMA/SMA, left insular cortex, inferior parietal lobe), although with significantly different structural weightings, in both nonmusicians and musicians. Additionally, musicians activated specific subcomponents only during verbal (right insular cortex) or only during tonal WM (right globus pallidus, right caudate nucleus, and left cerebellum). These results reveal the existence of two WM systems in musicians: A phonological loop supporting rehearsal of phonological information, and a tonal loop supporting rehearsal of tonal information. Differences between groups for tonal WM, and between verbal and tonal WM within musicians, were mainly related to structures involved in controlling, programming and planning of actions, thus presumably reflecting differences in action-related sensorimotor coding of verbal and tonal information.

Multichannel electroencephalograph signals from two broad groups, 10 musicians and 10 nonmusicians, recorded in different states (in resting states or no task condition, with eyes opened and eyes closed, and with two musical tasks, listening to two different pieces of music) were studied. Degrees of phase synchrony in various frequency bands were assessed. No differences in the degree of synchronization in any frequency band were found between the two groups in resting conditions. Yet, while listening to music, significant increases of synchronization were found only in the gamma-frequency range (>30 Hz) over large cortical areas for the group of musicians. This high degree of synchronization elicited by music in the group of musicians might be due to their ability to host long-term memory representations of music and mediate access to these stored representations.

Full Text Available Musical training leads to sensory and motor neuroplastic changes in the human brain. Motivated by findings on enlarged corpus callosum in musicians and asymmetric somatomotor representation in string players, we investigated the relationship between musical training, callosal anatomy, and interhemispheric functional symmetry during music listening. Functional symmetry was increased in musicians compared to nonmusicians, and in keyboardists compared to string players. This increased functional symmetry was prominent in visual and motor brain networks. Callosal size did not significantly differ between groups except for the posterior callosum in musicians compared to nonmusicians. We conclude that the distinctive postural and kinematic symmetry in instrument playing cross-modally shapes information processing in sensory-motor cortical areas during music listening. This cross-modal plasticity suggests that motor training affects music perception.

Musculoskeletal disorders, stress and performance anxiety are common in musicians. Therefore, some use the Alexander Technique (AT), a psycho-physical method that helps to release unnecessary muscle tension and re-educates non-beneficial movement patterns through intentional inhibition of unwanted habitual behaviours. According to a recent review AT sessions may be effective for chronic back pain. This review aimed to evaluate the evidence for the effectiveness of AT sessions on musicians' performance, anxiety, respiratory function and posture. The following electronic databases were searched up to February 2014 for relevant publications: PUBMED, Google Scholar, CINAHL, EMBASE, AMED, PsycINFO and RILM. The search criteria were "Alexander Technique" AND "music*". References were searched, and experts and societies of AT or musicians' medicine contacted for further publications. 237 citations were assessed. 12 studies were included for further analysis, 5 of which were randomised controlled trials (RCTs), 5 controlled but not randomised (CTs), and 2 mixed methods studies. Main outcome measures in RCTs and CTs were music performance, respiratory function, performance anxiety, body use and posture. Music performance was judged by external experts and found to be improved by AT in 1 of 3 RCTs; in 1 RCT comparing neurofeedback (NF) to AT, only NF caused improvements. Respiratory function was investigated in 2 RCTs, but not improved by AT training. Performance anxiety was mostly assessed by questionnaires and decreased by AT in 2 of 2 RCTs and in 2 of 2 CTs. A variety of outcome measures has been used to investigate the effectiveness of AT sessions in musicians. Evidence from RCTs and CTs suggests that AT sessions may improve performance anxiety in musicians. Effects on music performance, respiratory function and posture yet remain inconclusive. Future trials with well-established study designs are warranted to further and more reliably explore the potential of AT in the

The present study investigated the influence of musical expectations on auditory representations in musicians and non-musicians using magnetoencephalography (MEG). Neuroscientific studies have demonstrated that musical syntax is processed in the inferior frontal gyri, eliciting an early right anterior negativity (ERAN), and anatomical evidence has shown that interconnections occur between the frontal cortex and the belt and parabelt regions in the auditory cortex (AC). Therefore, we anticipated that musical expectations would mediate neural activities in the AC via an efferent pathway. To test this hypothesis, we measured the auditory-evoked fields (AEFs) of seven musicians and seven non-musicians while they were listening to a five-chord progression in which the expectancy of the third chord was manipulated (highly expected, less expected, and unexpected). The results revealed that highly expected chords elicited shorter N1m (negative AEF at approximately 100 ms) and P2m (positive AEF at approximately 200 ms) latencies and larger P2m amplitudes in the AC than less-expected and unexpected chords. The relations between P2m amplitudes/latencies and harmonic expectations were similar between the groups; however, musicians' results were more remarkable than those of non-musicians. These findings suggest that auditory cortical processing is enhanced by musical knowledge and long-term training in a top-down manner, which is reflected in shortened N1m and P2m latencies and enhanced P2m amplitudes in the AC.

Full Text Available A major question in systems neuroscience is how a single population of neurons can interact with the rest of the brain to orchestrate complex behavioral states. The hypothalamus contains many such discrete neuronal populations that individually regulate arousal, feeding, and drinking. For example, hypothalamic neurons that express hypocretin (Hcrt neuropeptides can sense homeostatic and metabolic factors affecting wakefulness and orchestrate organismal arousal. Neurons that express agouti-related protein (AgRP can sense the metabolic needs of the body and orchestrate a state of hunger. The organum vasculosum of the lamina terminalis (OVLT can detect the hypertonicity of blood and orchestrate a state of thirst. Each hypothalamic population is sufficient to generate complicated behavioral states through the combined efforts of distinct efferent projections. The principal challenge to understanding these brain systems is therefore to determine the individual roles of each downstream projection for each behavioral state. In recent years, the development and application of temporally precise, genetically encoded tools have greatly improved our understanding of the structure and function of these neural systems. This review will survey recent advances in our understanding of how these individual hypothalamic populations can orchestrate complicated behavioral states due to the combined efforts of individual downstream projections.

Recent studies disagree on whether musicians have an advantage over non-musicians in understanding speech in noise. However, it has been suggested that musicians may be able to use diferences in fundamental frequency (F0) to better understand target speech in the presence of interfering talkers....... Here we studied a relatively large (N=60) cohort of young adults, equally divided between nonmusicians and highly trained musicians, to test whether the musicians were better able to understand speech either in noise or in a two-talker competing speech masker. The target speech and competing speech...... were presented with either their natural F0 contours or on a monotone F0, and the F0 diference between the target and masker was systematically varied. As expected, speech intelligibility improved with increasing F0 diference between the target and the two-talker masker for both natural and monotone...

The ability to process auditory feedback for vocal pitch control is crucial during speaking and singing. Previous studies have suggested that musicians with absolute pitch (AP) develop specialized left-hemisphere mechanisms for pitch processing. The present study adopted an auditory feedback pitch perturbation paradigm combined with ERP recordings to test the hypothesis whether the neural mechanisms of the left-hemisphere enhance vocal pitch error detection and control in AP musicians compared with relative pitch (RP) musicians and non-musicians (NM). Results showed a stronger N1 response to pitch-shifted voice feedback in the right-hemisphere for both AP and RP musicians compared with the NM group. However, the left-hemisphere P2 component activation was greater in AP and RP musicians compared with NMs and also for the AP compared with RP musicians. The NM group was slower in generating compensatory vocal reactions to feedback pitch perturbation compared with musicians, and they failed to re-adjust their vocal pitch after the feedback perturbation was removed. These findings suggest that in the earlier stages of cortical neural processing, the right hemisphere is more active in musicians for detecting pitch changes in voice feedback. In the later stages, the left-hemisphere is more active during the processing of auditory feedback for vocal motor control and seems to involve specialized mechanisms that facilitate pitch processing in the AP compared with RP musicians. These findings indicate that the left hemisphere mechanisms of AP ability are associated with improved auditory feedback pitch processing during vocal pitch control in tasks such as speaking or singing.

To assess the potential clinical use, particularly in modulating stress, of changes in the cardiovascular and respiratory systems induced by music, specifically tempo, rhythm, melodic structure, pause, individual preference, habituation, order effect of presentation, and previous musical training. Measurement of cardiovascular and respiratory variables while patients listened to music. University research laboratory for the study of cardiorespiratory autonomic function. 12 practising musicians and 12 age matched controls. After a five minute baseline, presentation in random order of six different music styles (first for a two minute, then for a four minute track), with a randomly inserted two minute pause, in either sequence. Breathing rate, ventilation, carbon dioxide, RR interval, blood pressure, mid-cerebral artery flow velocity, and baroreflex. Ventilation, blood pressure, and heart rate increased and mid-cerebral artery flow velocity and baroreflex decreased with faster tempi and simpler rhythmic structures compared with baseline. No habituation effect was seen. The pause reduced heart rate, blood pressure, and minute ventilation, even below baseline. An order effect independent of style was evident for mid-cerebral artery flow velocity, indicating a progressive reduction with exposure to music, independent of style. Musicians had greater respiratory sensitivity to the music tempo than did non-musicians. Music induces an arousal effect, predominantly related to the tempo. Slow or meditative music can induce a relaxing effect; relaxation is particularly evident during a pause. Music, especially in trained subjects, may first concentrate attention during faster rhythms, then induce relaxation during pauses or slower rhythms.

Pop-rock musicians are at risk of developing hearing loss and other symptoms related to amplified music. The aim of the present study was to assess the satisfaction provided by the use of hearing protection in pop-rock musicians. Contemporary cohort study. A study of 23 male pop-rock musicians, aged between 25 to 45 years. After audiological evaluation (pure tone audiometry, middle ear analysis, TEOAE and DPOAE) hearing protective devices were provided to be used for three months. After that musicians answered a satisfaction assessment questionnaire. The prevalence of hearing loss was of 21.7%. The most common complaints about the hearing protectors were: autophonia, pressure in the ears, interference in high frequencies perception and full time use of the hearing protector during concerts. There was a positive correlation between a reduction in tinnitus after the use of the HPD with the following complaints: tinnitus after beginning the career (p= 0.044), discomfort with the sound intensity in the work place (p= 0.009) and intolerance to loud sound (p= 0.029). There was a high prevalence of hearing loss and a positive tendency towards the use of the ear protector device among the sample population.

The historically developed practice of learning to play a music instrument from notes instead of by imitation or improvisation makes it possible to contrast two types of skilled musicians characterized not only by dissimilar performance practices, but also disparate methods of audiomotor learning.
This paper discusses an exploration of the working lives of musicians working in a range of musical genres in the North East of England, revealing the factors that contribute to their ability to obtain a musical livelihood. These factors can be understood in terms of various forms of social, cultural and symbolic "capital" (Bourdieu,…

The aim of this study was to assess hearing and hearing disorders among rock/jazz musicians. One hundred and thirty-nine (43 women and 96 men) musicians participated. The results are based on pure-tone audiometry and questionnaire responses. According to our definition of hearing loss, tinnitus, hyperacusis, distortion and/or diplacusis as hearing disorders, we found disorders in 74%, of the rock/jazz musicians studied. Hearing loss, tinnitus and hyperacusis were most common, and the latter two were found significantly more frequently than in different reference populations. The women showed bilateral, significantly better hearing thresholds at 3-6 kHz than the men. Hyperacusis, and the combination of both hyperacusis and tinnitus, were found to be significantly more frequent among women than among men. Hearing loss and tinnitus were significantly more common among men than among women. It is important to evaluate all kinds of hearing problems (other than hearing loss) in musicians, since they represent an occupational group especially dependent on optimal, functional hearing. On the basis of our results, we suggest that hearing problems such as tinnitus, hyperacusis, distortion and/or diplacusis should, in addition to hearing loss, be defined as hearing disorders.

An investigation of the influence of trauma on musicians revealed concentration and memory problems as two of the most common symptoms hampering the performance of affected individuals. In many instances where the causes of these problems were related to trauma sequelae, these could clearly be linked to dissociative symptoms. The following…

The main focus of this thesis is the representation of jazz music and its musicians, and the ways in which American (black and white) critics, novelists, and musicians interpret this music from the development of bebop to free jazz. My aim is to reveal the complexities of the dialogue between white and black representations of jazz, as well as among the self-representations of African American musicians. To this end, I discuss the discourses of jazz that are embedded within the broader cultur...

The perception and neural representation of acoustically similar speech sounds underlie language development. Music training hones the perception of minute acoustic differences that distinguish sounds; this training may generalize to speech processing given that adult musicians have enhanced neural differentiation of similar speech syllables compared with nonmusicians. Here, we asked whether this neural advantage in musicians is present early in life by assessing musically trained and untrained children as young as age 3. We assessed auditory brainstem responses to the speech syllables /ba/ and /ga/ as well as auditory and visual cognitive abilities in musicians and nonmusicians across 3 developmental time-points: preschoolers, school-aged children, and adults. Cross-phase analyses objectively measured the degree to which subcortical responses differed to these speech syllables in musicians and nonmusicians for each age group. Results reveal that musicians exhibit enhanced neural differentiation of stop consonants early in life and with as little as a few years of training. Furthermore, the extent of subcortical stop consonant distinction correlates with auditory-specific cognitive abilities (i.e., auditory working memory and attention). Results are interpreted according to a corticofugal framework for auditory learning in which subcortical processing enhancements are engendered by strengthened cognitive control over auditory function in musicians.

Full Text Available Focal hand dystonia (FHD in musicians is a movement disorder causing abnormal movements and irregularities in playing. Since weak electrical currents applied to the brain induce persistent excitability changes in humans, cathodal tDCS was proposed as a possible non-invasive approach for modulating cortical excitability in patients with FHD. However, the optimal targets and modalities have still to be determined. In this pilot study, we delivered cathodal (2 mA, anodal (2 mA and sham tDCS over the motor areas bilaterally for 20 min daily for five consecutive days in two musicians with FHD. After cathodal tDCS, both patients reported a sensation of general wellness and improved symptoms of FHD. In conclusion, our pilot results suggest that cathodal tDCS delivered bilaterally over motor-premotor (M-PM cortex for 5 consecutive days may be effective in improving symptoms in FHD.

Full Text Available This paper discusses issues relating to informal education in Yoruba traditional music using the master musician as an important agent for propagating traditional knowledge and values. The study is an ethnographic research and uses oral interviews and other qualitative techniques for eliciting information. As part of its findings, the study found out that informal education in Yoruba culture follows a typical pattern of instruction which is acquired through heredity, apprentice under a well-known artist, observation and participation in communal activities. In the case of music, which is the focus of the study, it is promoted by the master musician, a position that could be occupied by men or women depending on the nature of the ensemble and the societal norms approved for such groups. In conclusion, it was suggested in the study that contemporary music educators and curriculum planners should tailor their curriculum to reflect the traditional values and practices of their people.

Difficulty perceiving music is often cited as one of the main problems facing hearing-impaired listeners. It has been suggested that musical enjoyment could be enhanced if sound information absent due to impairment is transmitted via other sensory modalities such as vision or touch. In this study...... the random melody. Tactile cues were applied to the listener’s fingers on half of the blocks. Results showed that tactile cues can significantly improve the melodic segregation ability in both musician and nonmusician groups in challenging listening conditions. Overall, the musician group performance...... was always better; however, the magnitude of improvement with the introduction of tactile cues was similar in both groups. This study suggests that hearing-impaired listeners could potentially benefit from a system transmitting such information via a tactile modality...

Musician's dystonia is known as a task specific dystonia. Though it is thought to occur during a long course of repetitive performance, the actual circumstances that precipitate this condition are not clear. According to factual reports this disease is not commonly known, probably because many of these patients may not have been visiting a hospital. We prepared a questionnaire and did a survey among the students of a music college. This is the first questionnaire survey aimed at finding out the prevalence of musician's dystonia among the students of music. Among the 480 participants of this survey, 29% of the students had knowledge of this disorder and 1.25% of the students had dystonia while performing music.

Full Text Available The integrity of the locomotor system can be compromised by the transport of certain objects, especially when done in an inadequate manner. Due to their weight and size, the transport of musical instruments can contribute to body dysfunctions in musicians who frequently have to carry their instruments, influencing balance andbody posture. Thus, the soil reaction force was investigated during the gait of a musician carrying or not his instrument. Two AMTI (Advanced Mechanical Technologies, Inc. platforms were used for kinetic data acquisition. A total of 40 measurements were obtainedfor gait and balance: 20 without carrying the instrument and 20 while carrying the instrument. The t test showed significant differences between the two situations for all variables analyzed. The results suggest that the locomotor system suffers alterationswhen carrying any kind of load, as was the case here in which the subject carried 7.75% of his own weight.

The reliability of the measurement of the distance between the posterior border of the acromion and the wall and the reliability of the modified lateral scapular slide test have not been studied. Overall, the reliability of the clinical tools used to assess scapular positioning has not been studied in musicians. To examine the intertester reliability of scapular observation and 2 clinical tests for the assessment of scapular positioning in musicians. Intertester reliability study. University research laboratory. Thirty healthy student musicians at a single university. Two assessors performed a standardized observation protocol, the measurement of the distance between the posterior border of the acromion and the wall, and the modified lateral scapular slide test. Each assessor was blinded to the other's findings. The intertester reliability coefficients (kappa) for the observation in relaxed position, during unloaded movement, and during loaded movement were 0.41, 0.63, and 0.36, respectively. The kappa values for the observation of tilting and winging at rest were 0.48 and 0.42, respectively; during unloaded movement, the kappa values were 0.52 and 0.78, respectively; and with a 1-kg load, the kappa values were 0.24 and 0.50, respectively. The intraclass correlation coefficient (ICC) of the measurement of the acromial distance was 0.72 in relaxed position and 0.75 with the participant actively retracting both shoulders. The ICCs for the modified lateral scapular slide test varied between 0.63 and 0.58. Our results demonstrated that the modified lateral scapular slide test was not a reliable tool to assess scapular positioning in these participants. Our data indicated that scapular observation in the relaxed position and during unloaded abduction in the frontal plane was a reliable assessment tool. The reliability of the measurement of the distance between the posterior border of the acromion and the wall in healthy musicians was moderate.

Aphasia coupled with amusia is reported in a 73-year-old male musician who was a lawyer by profession. This condition followed an ischemic stroke in the lateral aspect of the parieto-occipital region of the left hemisphere. The patient's music production exhibits jargon amusia, similar to that in his verbal production. This case supports the thesis that language and music may share a common hemisphere.

Behavioural and neuroimaging studies provide evidence for a possible "sensitive" period in childhood development during which musical training results in long-lasting changes in brain structure and auditory and motor performance. Previous work from our laboratory has shown that adult musicians who begin training before the age of 7 (early-trained; ET) perform better on a visuomotor task than those who begin after the age of 7 (late-trained; LT), even when matched on total years of musical training and experience. Two questions were raised regarding the findings from this experiment. First, would this group performance difference be observed using a more familiar, musically relevant task such as auditory rhythms? Second, would cognitive abilities mediate this difference in task performance? To address these questions, ET and LT musicians, matched on years of musical training, hours of current practice and experience, were tested on an auditory rhythm synchronization task. The task consisted of six woodblock rhythms of varying levels of metrical complexity. In addition, participants were tested on cognitive subtests measuring vocabulary, working memory and pattern recognition. The two groups of musicians differed in their performance of the rhythm task, such that the ET musicians were better at reproducing the temporal structure of the rhythms. There were no group differences on the cognitive measures. Interestingly, across both groups, individual task performance correlated with auditory working memory abilities and years of formal training. These results support the idea of a sensitive period during the early years of childhood for developing sensorimotor synchronization abilities via musical training.

Rhythm and melody are two basic characteristics of music. Performing musicians have to pay attention to both, and avoid errors in either aspect of their performance. To investigate the neural processes involved in detecting melodic and rhythmic errors from auditory input we tested musicians on both kinds of deviations in a mismatch negativity (MMN) design. We found that MMN responses to a rhythmic deviation occurred at shorter latencies than MMN responses to a melodic deviation. Beamformer source analysis showed that the melodic deviation activated superior temporal, inferior frontal and superior frontal areas whereas the activation pattern of the rhythmic deviation focused more strongly on inferior and superior parietal areas, in addition to superior temporal cortex. Activation in the supplementary motor area occurred for both types of deviations. We also recorded responses to similar pitch and tempo deviations in a simple, non-musical repetitive tone pattern. In this case, there was no latency difference between the MMNs and cortical activation was smaller and mostly limited to auditory cortex. The results suggest that prediction and error detection of musical stimuli in trained musicians involve a broad cortical network and that rhythmic and melodic errors are processed in partially different cortical streams.

College musicians exhibit greater declines in hearing than the general population and are at particular risk because they rehearse and perform daily in loud environments. Also, they engage in use of personal listening devices which increases the amount of "exposure" time. Despite increased risk, many do not use hearing protection devices (HPD). The purpose of this study was to (1) to identify the present level of education about hearing health, (2) identify the perceived advantages and disadvantages of using HPD, and (3) evaluate results among different musical instrument groups. A mixed-methods group design was used including both quantitative and qualitative instruments. SPSS was used to generate descriptive statistics, and non-parametric statistical analysis was performed on quantitative data. NVivo software was used to evaluate qualitative responses. Of the 90 college instrumental music students who participated, 12% reported a history of hearing loss, and over one-third reported tinnitus. Seventy-seven percent of participants had never received any training about hearing health and only a small percentage of students used HPD. The most cited reason for lack of protection use was its negative impact on sound quality. However, group differences were noted between brass, woodwind, and percussion musicians in terms of HPD uptake. Improving the type of information disseminated to college musicians may reduce the risk of ear-related deficits. Noise dosage information, HPD information, and prevention education grounded in theories like the Health Belief Model may increase awareness and promote greater use of HPDs in this population.

Music performance anxiety affects numerous musicians, with many of them reporting impairment of performance due to this problem. This exploratory study investigated the effects of virtual reality exposure training on students with music performance anxiety. Seventeen music students were randomly assigned to a control group (n=8) or a virtual training group (n=9). Participants were asked to play a musical piece by memory in two separate recitals within a 3-week interval. Anxiety was then measured with the Personal Report of Confidence as a Performer Scale and the S-Anxiety scale from the State-Trait Anxiety Inventory (STAI-Y). Between pre- and post-tests, the virtual training group took part in virtual reality exposure training consisting of six 1-hour long sessions of virtual exposure. The results indicate a significant decrease in performance anxiety for musicians in the treatment group for those with a high level of state anxiety, for those with a high level of trait anxiety, for women, and for musicians with high immersive tendencies. Finally, between the pre- and post-tests, we observed a significant increase in performance quality for the experimental group, but not for the control group.

Musical performance requires extremely fast and dexterous limb movements. The underlying biological mechanisms have been an object of interest among scientists and non-scientists for centuries. Numerous studies of musicians and non-musicians have demonstrated that neuroplastic adaptations through early and deliberate musical training endowed superior motor skill. However, little has been unveiled about what makes inter-individual differences in motor skills among musicians. Here we determined the attributes of inter-individual differences in the maximum rate of repetitive piano keystrokes in twenty-four pianists. Among various representative factors of neuromuscular functions, anatomical characteristics, and training history, a stepwise multiple regression analysis and generalized linear model identified two predominant predictors of the maximum rate of repetitive piano keystrokes; finger tapping rate and muscular strength of the elbow extensor. These results suggest a non-uniform role of individual limb muscles in the production of extremely fast repetitive multi-joint movements. Neither age of musical training initiation nor the amount of extensive musical training before age twenty was a predictor. Power grip strength was negatively related to the maximum rate of piano keystrokes only during the smallest tone production. These findings highlight the importance of innate biological nature and explicit training for motor virtuosity.

Long-term music training can improve sensorimotor skills, as playing a musical instrument requires the functional integration of information related to multimodal sensory perception and motor execution. This functional integration often leads to functional reorganization of cerebral cortices, including auditory, visual, and motor areas. Moreover, music appreciation can modulate emotions (e.g., stress relief), and long-term music training can enhance a musician's self-control and self-evaluation ability. Therefore, the neural processing of music can also be related to certain higher brain cognitive functions. However, evidence demonstrating that long-term music training modulates higher brain functions is surprisingly rare. Here, we aimed to comprehensively explore the neural changes induced by long-term music training by assessing the differences of transient and quasi-steady-state auditory-evoked potentials between nonmusicians and musicians. We observed that compared to nonmusicians, musicians have (1) larger high-frequency steady-state responses, which reflect the auditory information processing within the sensory system, and (2) smaller low-frequency vertex potentials, which reflect higher cognitive information processing within the novelty/saliency detection system. Therefore, we speculate that long-term music training facilitates "bottom-up" auditory information processing in the sensory system and enhances "top-down" cognitive inhibition of the novelty/saliency detection system.
Full Text Available Current web-based GIS or RS applications generally rely on centralized structure, which has inherent drawbacks such as single points of failure, network congestion, and data inconsistency, etc. The inherent disadvantages of traditional GISs need to be solved for new applications on Internet or Web. Decentralized orchestration offers performance improvements in terms of increased throughput and scalability and lower response time. This paper investigates build time and runtime issues related to decentralized orchestration of composite geospatial processing services based on OGC WPS standard specification. A case study of dust storm detection was demonstrated to evaluate the proposed method and the experimental results indicate that the method proposed in this study is effective for its ability to produce the high quality solution at a low cost of communications for geospatial processing service composition problem.

With Bio-jETI, we introduce a service platform for interdisciplinary work on biological application domains and illustrate its use in a concrete application concerning statistical data processing in R and xcms for an LC/MS analysis of FAAH gene knockout. Bio-jETI uses the jABC environment for service-oriented modeling and design as a graphical process modeling tool and the jETI service integration technology for remote tool execution. As a service definition and provisioning platform, Bio-jETI has the potential to become a core technology in interdisciplinary service orchestration and technology transfer. Domain experts, like biologists not trained in computer science, directly define complex service orchestrations as process models and use efficient and complex bioinformatics tools in a simple and intuitive way.
Full Text Available The mobile cloud computing (MCC that combines mobile computing and cloud concept takes wireless access network as the transmission medium and uses mobile devices as the client. When offloading the complicated multitask application to the MCC environment, each task executes individually in terms of its own computation, storage, and bandwidth requirement. Due to user’s mobility, the provided resources contain different performance metrics that may affect the destination choice. Nevertheless, these heterogeneous MCC resources lack integrated management and can hardly cooperate with each other. Thus, how to choose the appropriate offload destination and orchestrate the resources for multitask is a challenge problem. This paper realizes a programming resource provision for heterogeneous energy-constrained computing environments, where a software defined controller is responsible for resource orchestration, offload, and migration. The resource orchestration is formulated as multiobjective optimal problem that contains the metrics of energy consumption, cost, and availability. Finally, a particle swarm algorithm is used to obtain the approximate optimal solutions. Simulation results show that the solutions for all of our studied cases almost can hit Pareto optimum and surpass the comparative algorithm in approximation, coverage, and execution time.

One of the main challenges for e-government is to create coherent services for citizens and businesses. Realizing Integrated Service Delivery (ISD) requires government agencies to collaborate across their organizational boundaries. The coordination of processes across multiple organizations to realize ISD is called orchestration. One way of achieving orchestration is to formalize processes using architecture. In this chapter we identify architectural principles for orchestration by looking at three case studies of cross-organizational service delivery chain formation in the Netherlands. In total, six generic principles were formulated and subsequently validated in two workshops with experts. These principles are: (i) build an intelligent front office, (ii) give processes a clear starting point and end, (iii) build a central workflow application keeping track of the process, (iv) differentiate between simple and complex processes, (v) ensure that the decision-making responsibility and the overview of the process are not performed by the same process role, and (vi) create a central point where risk profiles are maintained. Further research should focus on how organizations can adapt these principles to their own situation.

Full Text Available As digital technologies permeate every aspect of our lives, the complexity of the educational settings, and of the technological support we use within them, unceasingly rises. This increased complexity, along with the need for educational practitioners to apply such technologies within multi-constraint authentic settings, has given rise to the notion of technology-enhanced learning practice as “orchestration of learning”. However, at the same time, the complexity involved in evaluating the benefits of such educational technologies has also increased, prompting questions about the way evaluators can cope with the different places, technologies, informants and issues involved in their evaluation activity. By proposing the notion of “orchestrating evaluation”, this paper tries to reconcile the often disparate “front office accounts” of research publications and the “shop floor practice” of evaluation of educational technology, through the case study of evaluating a system to help teachers in coordinating computer-supported collaborative learning (CSCL scenarios. We reuse an internationally-evaluated conceptual framework of “orchestration aspects” (design, management, adaptation, pragmatism, etc. to structure the case‟s narrative, showing how the original evaluation questions and methods were modulated in the face of the multiple (authentic evaluation setting constraints.

Full Text Available Taking account of the object of study and of the type of musical and pedagogical practices found in the monographies written by undergraduate students from the professionalization program Creative Colombia (first cohort, it could be argued that their musical and pedagogical knowledge is not egocentrically centered in themselves, and that, on the contrary, they try to build bridges and interconnections with other arts and areas of knowledge, proving thus that the musical art is an essential part of their daily work and constitutes a vivid experience in terms of cultural transformation. There were then proposed several processes of social change in the realm of the school’s micro-universe, the classroom, the town’s Cultural House, its municipal band, etc. In those various processes, the music teacher was seen as a political person capable of using his musical knowledge to mediate in social realities, as a musicianmediator. So, it became clear that the real task was not to form mere musical trainers, but cultural mediators who may understand their artistic practice and teaching as an opportunity to acquire a deeper understanding of culture, as well as the means to transform it. Along the whole process, the students leaned on the trend and perspective of constructivism.

Studies investigating factors that influence tone recognition generally use recognition tests, whereas the majority of the studies on verbal material use self-generated responses in the form of serial recall tests. In the present study we intended to investigate whether tonal and verbal materials share the same cognitive mechanisms, by presenting an experimental instrument that evaluates short-term and working memories for tones, using self-generated sung responses that may be compared to verbal tests. This paradigm was designed according to the same structure of the forward and backward digit span tests, but using digits, pseudowords, and tones as stimuli. The profile of amateur singers and professional singers in these tests was compared in forward and backward digit, pseudoword, tone, and contour spans. In addition, an absolute pitch experimental group was included, in order to observe the possible use of verbal labels in tone memorization tasks. In general, we observed that musical schooling has a slight positive influence on the recall of tones, as opposed to verbal material, which is not influenced by musical schooling. Furthermore, the ability to reproduce melodic contours (up and down patterns) is generally higher than the ability to reproduce exact tone sequences. However, backward spans were lower than forward spans for all stimuli (digits, pseudowords, tones, contour). Curiously, backward spans were disproportionately lower for tones than for verbal material-that is, the requirement to recall sequences in backward rather than forward order seems to differentially affect tonal stimuli. This difference does not vary according to musical expertise.
Full Text Available With the development of ethnomusicology from a comparative discipline to an anthropologically oriented science there has been an increase in the significance of the biography of folk musicians as scientific sources. The intention of the anthropological thought to accept and theoretically consider human nature as open and dynamic, has been realized in the ethnomusicological plane through the understanding of music as a product of thinking and behaviour of a particular musician in given circumstances. The concept of an artist is especially complex in the field of oral music culture, where creation and performance are connected in one person and the transferring process involves direct communication. The attempt to overcome the dichotomy of the musicological and sociological, i. e. anthropological attitude in ethnomusicology by synthesizing concepts which involve music, culture and man has brought particular importance to the relations between individual biographies and 'biographies of the collective' - relevant historical ethnological, anthropological, sociological, culturological, religion ideological and other types of data. Observations enlightening the social side of the folk musician's personality make the necessary 'frame' for the biography: from 'objective' social circumstances which modelled it to the opinion of the cultural environment about his performing. The folk musician's biography oriented towards ethnomusicology involves the result of a critical evaluation of the picture based on the emic and ethic vision autobiographical data and the observations of others, primarily researchers. The complexity of a biographical discourse in ethnomusicology can be perfectly seen in the example of the gusle-player's biography, as a genre-determined solo role in the tradition. For studying the relation between a person and a style of music expression, concerning gusle-players it is important to bear in mind the change in the profile of gusle

Two experiments were performed to examine musicians' and nonmusicians' electroencephalographic (EEG) responses to changes in major dimensions (tempo, melody, and key) of classical music. In Exp. 1, 12 nonmusicians' and 12 musicians' EEGs during melody and tempo changes in classical music showed more alpha desynchronization in the left hemisphere (F3) for changes in tempo than in the right. For melody, the nonmusicians were more right-sided (F4) than left in activation, and musicians showed no left-right differences. In Exp. 2, 18 musicians' and 18 nonmusicians' EEG after a key change in classical music showed that distant key changes elicited more right frontal (F4) alpha desynchronization than left. Musicians showed more reaction to key changes than nonmusicians and instructions to attend to key changes had no significant effect. Classical music, given its well-defined structure, offers a unique set of stimuli to study the brain. Results support the concept of hierarchical modularity in music processing that may be automatic.

Music performance anxiety (MPA) is a distressing experience for musicians of all ages, yet the empirical investigation of MPA in adolescents has received little attention to date. No measures specifically targeting MPA in adolescents have been empirically validated. This article presents findings of an initial study into the psychometric properties and validation of the Music Performance Anxiety Inventory for Adolescents (MPAI-A), a new self-report measure of MPA for this group. Data from 381 elite young musicians aged 12-19 years was used to investigate the factor structure, internal reliability, construct and divergent validity of the MPAI-A. Cronbach's alpha for the full measure was .91. Factor analysis identified three factors, which together accounted for 53% of the variance. Construct validity was demonstrated by significant positive relationships with social phobia (measured using the Social Phobia Anxiety Inventory [Beidel, D. C., Turner, S. M., & Morris, T. L. (1995). A new inventory to assess childhood social anxiety and phobia: The Social Phobia and Anxiety Inventory for Children. Psychological Assessment, 7(1), 73-79; Beidel, D. C., Turner, S. M., & Morris, T. L. (1998). Social Phobia and Anxiety Inventory for Children (SPAI-C). North Tonawanda, NY: Multi-Health Systems Inc.]) and trait anxiety (measured using the State Trait Anxiety Inventory [Spielberger, C. D. (1983). State-Trait Anxiety Inventory STAI (Form Y). Palo Alto, CA: Consulting Psychologists Press, Inc.]). The MPAI-A demonstrated convergent validity by a moderate to strong positive correlation with an adult measure of MPA. Discriminant validity was established by a weaker positive relationship with depression, and no relationship with externalizing behavior problems. It is hoped that the MPAI-A, as the first empirically validated measure of adolescent musicians' performance anxiety, will enhance and promote phenomenological and treatment research in this area.
Full Text Available This study examined the effects of music genre and tempo on brain activation patterns in 10 nonmusicians.Two genres (rock and jazz and three tempos (slowed, medium/normal, andquickened were examined using EEG recording and analyzed through Fast Fourier Transform(FFT analysis. When participants listened to their preferred genre, an increase in alpha waveamplitude was observed. Alpha waves were not significantly affected by tempo. Beta waveamplitude increased significantly as the tempo increased. Genre had no effect on beta waves. Thefindings of this study indicate that genre preference and artificially modified tempo do affectalpha and beta wave activation in non-musicians listening to preselected songs.

The big six recording labels are making a push to incorporate the Internet into their distribution process. Standing in their way is the issue of security. It seems that music files on the Internet, no matter how secure they may seem, are susceptible to tampering. This will force a shift in distribution away f...

Full Text Available Tuberculosis causes more annual deaths globally than any other infectious disease. However, progress in developing novel vaccines, diagnostics, and therapies has been hampered by an incomplete understanding of the immune response to Mycobacterium tuberculosis (Mtb. While the role of many immune cells has been extensively explored, mast cells (MCs have been relatively ignored. MCs are tissue resident cells involved in defense against bacterial infections playing an important role mediating immune cell crosstalk. This review discusses specific interactions between MCs and Mtb, their contribution to both immunity and disease pathogenesis, and explores their role in orchestrating other immune cells against infections.

The Automation Hooks Architecture Trade Study for Flexible Test Orchestration sought a standardized data-driven alternative to conventional automated test programming interfaces. The study recommended composing the interface using multicast DNS (mDNS/SD) service discovery, Representational State Transfer (Restful) Web Services, and Automatic Test Markup Language (ATML). We describe additional efforts to rapidly mature the Automation Hooks Architecture candidate interface definition by validating it in a broad spectrum of applications. These activities have allowed us to further refine our concepts and provide observations directed toward objectives of economy, scalability, versatility, performance, severability, maintainability, scriptability and others.

Ensemble musicians typically exchange visual cues to coordinate piece entrances. "Cueing-in" gestures indicate when to begin playing and at what tempo. This study investigated how timing information is encoded in musicians' cueing-in gestures. Gesture acceleration patterns were expected to indicate beat position, while gesture periodicity, duration, and peak gesture velocity were expected to indicate tempo. Same-instrument ensembles (e.g., piano-piano) were expected to synchronize more successfully than mixed-instrument ensembles (e.g., piano-violin). Duos performed short passages as their head and (for violinists) bowing hand movements were tracked with accelerometers and Kinect sensors. Performers alternated between leader/follower roles; leaders heard a tempo via headphones and cued their partner in nonverbally. Violin duos synchronized more successfully than either piano duos or piano-violin duos, possibly because violinists were more experienced in ensemble playing than pianists. Peak acceleration indicated beat position in leaders' head-nodding gestures. Gesture duration and periodicity in leaders' head and bowing hand gestures indicated tempo. The results show that the spatio-temporal characteristics of cueing-in gestures guide beat perception, enabling synchronization with visual gestures that follow a range of spatial trajectories.
Full Text Available The article provides opinions of some Beijing experimental electronic musicians about the situation of contemporary art in China and in the world, primarily about the background of the so called Christmas performance in Art District 798's gallery UCCA in Beijing. This was a sort of protest against destroying art with commercialization as the only measure of art gallery's success. The article first describes the situation of contemporary art in the world at the beginning of 21st century as it is described in Julian Stallabrass' book Art Incorporated. It can be deduced from the words of experimental electronic musicians in Beijing that the situation is similar in China. During the debate about the Christmas performance in UCCA gallery, a problem with galleries was emphasize. These became more similar to tourist venues than places for enriching one's thoughts and awareness about the world surrounding us, through artwork. Therefore, the Christmas performance tried to express this sentiment. It offered visitors a tourist show brought to the point of absurd. The employees and the leader of UCCA couldn't comprehend the symbolic meaning of this happening, which, symbolically, took place on Christmas, the most commercialized holiday in the West as well as in China.

Absolute pitch (AP) is widely believed to be a rare ability possessed by only a small group of gifted and special individuals (AP possessors). While AP has fascinated psychologists, neuroscientists, and musicians for more than a century, no theory can satisfactorily explain why this ability is so rare and difficult to learn. Here, we show that AP ability appears rare because of the methodological issues of the standard pitch-naming test. Specifically, the standard test unnecessarily poses a high decisional demand on AP judgments and uses a testing context that is highly inconsistent with one's musical training. These extra cognitive challenges are not central to AP memory per se and have thus led to consistent underestimation of AP ability in the population. Using the standard test, we replicated the typical findings that the accuracy for general violinists was low (12.38 %; chance level = 0 %). With identical stimuli, scoring criteria, and participants, violinists attained 25 % accuracy in a pitch verification test in which the decisional demand of AP judgment was reduced. When the testing context was increasingly similar to their musical experience, verification accuracy improved further and reached 39 %, three times higher than that for the standard test. Results were replicated with a separate group of pianists. Our findings challenge current theories about AP and suggest that the prevalence of AP among musicians has been highly underestimated in prior work. A multimodal framework is proposed to better explain AP memory.
Full Text Available Noise-induced hearing loss is an important public health issue, especially among musicians who are, more than any other occupation, dependent on their hearing. For them, hearing impairment is due to too loud music, the effect of which, if exceeding the limit depending on the individual sensitivity of one’s ear, can be compared with theeffect of noise on the ear. Risk factors for its development are: the type of musical instrument and sound character, the way of playing, music genre or composition, duration of exposure to loud music, sound source and its distance from the ear, intervals of acoustic stimuli, individual factors and the musician’s position in the orchestra. Hearing impairment is greater at higher frequencies; in pure tone audiogram it is shown as notches between 3000 and 6000 Hz and is most frequent in the wind and brass section. Hearing loss is greater among violinists and typically affects the left ear owing to the sound source proximity and their position in the orchestra. The most common health problems take the form of diplacusis, algiacusis and tinnitus, as exposure to the loud acoustic stimulus above 90 dB(A cause damage to the inner ear, the so-called acoustic trauma. Use of personal protective equipment among musicians is low especially because of too much high-frequency attenuation and occlusion effect.

Musical imagery is the human experience of imagining music without actually hearing it. The neural basis of this mental ability is unclear, especially for musicians capable of engaging in accurate and vivid musical imagery. Here, we created a visualization of an 8-minute symphony as a silent movie and used it as real-time cue for musicians to continuously imagine the music for repeated and synchronized sessions during functional magnetic resonance imaging (fMRI). The activations and networks evoked by musical imagery were compared with those elicited by the subjects directly listening to the same music. Musical imagery and musical perception resulted in overlapping activations at the anterolateral belt and Wernicke's area, where the responses were correlated with the auditory features of the music. Whereas Wernicke's area interacted within the intrinsic auditory network during musical perception, it was involved in much more complex networks during musical imagery, showing positive correlations with the dorsal attention network and the motor-control network and negative correlations with the default-mode network. Our results highlight the important role of Wernicke's area in forming vivid musical imagery through bilateral and anti-correlated network interactions, challenging the conventional view of segregated and lateralized processing of music versus language.
Playing a musical instrument is an intense, multisensory, and motor experience that usually commences at an early age and requires the acquisition and maintenance of a range of sensory and motor skills over the course of a musician's lifetime. Thus, musicians offer an excellent human model for studying behavioral-cognitive as well as brain effects of acquiring, practicing, and maintaining these specialized skills. Research has shown that repeatedly practicing the association of motor actions with specific sound and visual patterns (musical notation), while receiving continuous multisensory feedback will strengthen connections between auditory and motor regions (e.g., arcuate fasciculus) as well as multimodal integration regions. Plasticity in this network may explain some of the sensorimotor and cognitive enhancements that have been associated with music training. Furthermore, the plasticity of this system as a result of long term and intense interventions suggest the potential for music making activities (e.g., forms of singing) as an intervention for neurological and developmental disorders to learn and relearn associations between auditory and motor functions such as vocal motor functions. © 2015 Elsevier B.V.

Remembering autobiographical events can be associated with detailed visual imagery. The medial temporal lobe (MTL), precuneus and prefrontal cortex are held to jointly enable such vivid retrieval, but how these regions are orchestrated remains unclear. An influential prediction from animal physiology is that neural oscillations in theta frequency may be important. In this experiment, participants prospectively collected audio recordings describing personal autobiographical episodes or semantic knowledge over 2 to 7 months. These were replayed as memory retrieval cues while recording brain activity with magnetoencephalography (MEG). We identified a peak of theta power within a left MTL region of interest during both autobiographical and General Semantic retrieval. This MTL region was selectively phase-synchronized with theta oscillations in precuneus and medial prefrontal cortex, and this synchrony was higher during autobiographical as compared to General Semantic knowledge retrieval. Higher synchrony also predicted more detailed visual imagery during retrieval. Thus, theta phase-synchrony orchestrates in humans the MTL with a distributed neocortical memory network when vividly remembering autobiographical experiences. © 2013.

Full Text Available Monoamines provide chemical codes of behavioral states. However, the neural mechanisms of monoaminergic orchestration of behavior are poorly understood. Touch elicits an escape response in Caenorhabditis elegans where the animal moves backward and turns to change its direction of locomotion. We show that the tyramine receptor SER-2 acts through a Gαo pathway to inhibit neurotransmitter release from GABAergic motor neurons that synapse onto ventral body wall muscles. Extrasynaptic activation of SER-2 facilitates ventral body wall muscle contraction, contributing to the tight ventral turn that allows the animal to navigate away from a threatening stimulus. Tyramine temporally coordinates the different phases of the escape response through the synaptic activation of the fast-acting ionotropic receptor, LGC-55, and extrasynaptic activation of the slow-acting metabotropic receptor, SER-2. Our studies show, at the level of single cells, how a sensory input recruits the action of a monoamine to change neural circuit properties and orchestrate a compound motor sequence.

The efficacy of using sung words as a mnemonic device for verbal memory has been documented in persons with probable Alzheimer's dementia (AD), but it is not yet known whether this effect is related to music training. Given that music training can enhance cognitive functioning, we explored the effects of music training and modality (sung vs. spoken) on verbal memory in persons with and without AD. We used a mixed factorial design to compare learning (5 trials), delayed recall (30-min and, 24-hour), and recognition of sung versus spoken information in 22 healthy elderly (15 musicians), and 11 people with AD (5 musicians). Musicians with AD showed better total learning (over 5 trials) of sung information than nonmusicians with AD. There were no significant differences in delayed recall and recognition accuracy (of either modality) between musicians with and without AD, suggesting that music training may facilitate memory function in AD. Analysis of individual performances showed that two of the five musicians with AD were able to recall some information on delayed recall, whereas the nonmusicians with AD recalled no information on delay. The only significant finding in regard to modality (sung vs. spoken) was that total learning was significantly worse for sung than spoken information for nonmusicians with AD. This may be due to the need to recode information presented in song into spoken recall, which may be more cognitively demanding for this group. This is the first study to demonstrate that music training modulates memory of sung and spoken information in AD. The mechanism underlying these results is unclear, but may be due to music training, higher cognitive abilities, or both. Our findings highlight the need for further research into the potentially protective effect of music training on cognitive abilities in our aging population.

The intestine represents the largest and most elaborate immune system organ, in which dynamic and reciprocal interplay among numerous immune and epithelial cells, commensal microbiota, and external antigens contributes to establishing both homeostatic and pathologic conditions. The mechanisms that sustain gut homeostasis are pivotal in maintaining gut health in the harsh environment of the gut lumen. Intestinal epithelial cells are critical players in creating the mucosal platform for interplay between host immune cells and luminal stress inducers. Thus, knowledge of the epithelial interface between immune cells and the luminal environment is a prerequisite for a better understanding of gut homeostasis and pathophysiologies such as inflammation. In this review, we explore the importance of the epithelium in limiting or promoting gut inflammation (e.g., inflammatory bowel disease). We also introduce recent findings on how small RNAs such as microRNAs orchestrate pathophysiologic gene regulation. [BMB Reports 2016; 49(5): 263-269].

The project Collaborative, Complex and Critical Decision-Support in Evolving Crises (TRIDEC), co-funded by the European Commission in its Seventh Framework Programme focuses on real-time intelligent information management in earth management. The addressed challenges include the design and implementation of a robust and scalable service infrastructure supporting the integration of existing resources, components and systems. Key challenge for TRIDEC is establishing a network of independent systems, cooperatively interacting as a collective in a system-of-systems (SoS). For this purpose TRIDEC adopts enhancements of service-oriented architecture (SOA) principles in terms of an event-driven architecture (EDA) design (SOA 2.0). In this way TRIDEC establishes large-scale concurrent and intelligent information management of a manifold of crisis types by focusing on the integration of autonomous, task-oriented and geographically distributed systems. To this end TRIDEC adapts both ways SOA 2.0 offers: orchestration and choreography. In orchestration, a central knowledge-based processing framework takes control over the involved services and coordinates their execution. Choreography on the other hand avoids central coordination. Rather, each system involved in the SoS follows a global scenario without a single point of control but specifically defined (enacted, agreed upon) trigger conditions. More than orchestration choreography allows collaborative business processes of various heterogeneous sub-systems (e.g. cooperative decision making) by concurrent Complex Event Processing (CEP) and asynchronous communication. These types of interaction adapt the concept of decoupled relationships between information producers (e.g. sensors and sensor systems) and information consumers (e.g. warning systems and warning dissemination systems). Asynchronous communication is useful if a participant wants to trigger specific actions by delegating the responsibility (separation of concerns

This paper describes on-going research on streamlining the access and use of spatial data and processes in Australia. Spatial data in Australia is available on-line at many levels of government from local authorities, state and territories (jurisdictions), and nationally from the Commonwealth and other sources. Much of this data is available via Open Geospatial Consortium and World Wide Web Consortium standard web services. This abstract discusses three related research topics that have been identified by a wide range of stakeholders through a comprehensive consultation process. These are search and discovery, federation and orchestration of data and processes. The commonality across the three research topics is that they all require Semantic Web and Artificial Intelligence methods and embrace the various standards, and if needed, propose modifications to such standards.

Interorganellar cooperation maintained via exquisitely controlled retrograde-signaling pathways is an evolutionary necessity for maintenance of cellular homeostasis. This signaling feature has therefore attracted much research attention aimed at improving understanding of the nature of these communication signals, how the signals are sensed, and ultimately the mechanism by which they integrate targeted processes that collectively culminate in organellar cooperativity. The answers to these questions will provide insight into how retrograde-signal-mediated regulatory mechanisms are recruited and which biological processes are targeted, and will advance our understanding of how organisms balance metabolic investments in growth against adaptation to environmental stress. This review summarizes the present understanding of the nature and the functional complexity of retrograde signals as integrators of interorganellar communication and orchestrators of plant development, and offers a perspective on the future of this critical and dynamic area of research.

Full Text Available In the early 20th century, Salamanca hosted one of the most culturally and musically active families of the city during the first three decades of the century: the De- Bernardis. Their activities as organ builders, musicians, teachers and music entrepreneurs, focused on the figures of Juan De-Bernardi and his son Luis, left a mark not only in the town, through their involvement in numerous cultural events, but also building and reparing various instruments in an area that covers from the North of Portugal to the South of Cáceres. Here we reconstruct, through the information given by local hemerographic sources, their trajectory from their arrival in Salamanca in 1903 until 1932.

The combined influence of tempo and mode on emotional responses to music was studied by crossing 7 changes in mode with 3 changes in tempo. Twenty-four musicians aged 19 to 25 years (12 males and 12 females) and 24 nonmusicians aged 17 to 25 years (12 males and 12 females) were required to perform two tasks: 1) listening to different musical excerpts, and 2) associating an emotion to them such as happiness, serenity, fear, anger, or sadness. ANOVA showed that increasing the tempo strongly affected the arousal (F(2,116) = 268.62, mean square error (MSE) = 0.6676, P effects were found between tempo and mode (F (1,58) = 115.6, MSE = 0.6428, P effects. This finding demonstrates that small changes in the pitch structures of modes modulate the emotions associated with the pieces, confirming the cognitive foundation of emotional responses to music.
Full Text Available Previous studies have used task-related fMRI to investigate the neural basis of pitch identification (PI, but no study has examined the associations between resting-state functional connectivity (RSFC and PI ability. Using a large sample of Chinese non-musicians (N = 320, with 56 having prior musical training, the current study examined the associations among musical training, PI ability, and RSFC. Results showed that musical training was associated with increased RSFC within the networks for multiple cognitive functions (such as vision, phonology, semantics, auditory encoding, and executive functions. PI ability was associated with RSFC with regions for perceptual and auditory encoding for participants with musical training, and with RSFC with regions for short-term memory, semantics, and phonology for participants without musical training.

Replication is considered one of the most important techniques to improve the Quality of Services (QoS) of published Web Services. It has achieved impressive success in managing resource sharing and usage in order to moderate the energy consumed in IT environments. For a robust and successful replication process, attention should be paid to suitable time as well as the constraints and capabilities in which the process runs. The replication process is time-consuming since outsourcing some new replicas into other hosts is lengthy. Furthermore, nowadays, most of the business processes that might be implemented over the Web are composed of multiple Web services working together in two main styles: Orchestration and Choreography. Accomplishing a replication over such business processes is another challenge due to the complexity and flexibility involved. In this paper, we present an adaptive replication framework for regular and orchestrated composite Web services. The suggested framework includes a number of components for detecting unexpected and unhappy events that might occur when consuming the original published web services including failure or overloading. It also includes a specific replication controller to manage the replication process and select the best host that would encapsulate a new replica. In addition, it includes a component for predicting the incoming load in order to decrease the time needed for outsourcing new replicas, enhancing the performance greatly. A simulation environment has been created to measure the performance of the suggested framework. The results indicate that adaptive replication with prediction scenario is the best option for enhancing the performance of the replication process in an online business environment.

Geoprocessing service orchestration (GSO) provides a unified and flexible way to implement cross-application, long-lived, and multi-step geoprocessing service workflows by coordinating geoprocessing services collaboratively. Usually, geoprocessing services and geoprocessing service workflows are data and/or computing intensive. The intensity feature may make the execution process of a workflow time-consuming. Since it initials an execution request without blocking other interactions on the client side, an asynchronous mechanism is especially appropriate for GSO workflows. Many critical problems remain to be solved in existing asynchronous patterns for GSO including difficulties in improving performance, status tracking, and clarifying the workflow structure. These problems are a challenge when orchestrating performance efficiency, making statuses instantly available, and constructing clearly structured GSO workflows. A Fully Asynchronous and Status-Tracking (FAST) pattern that adopts asynchronous interactions throughout the whole communication tier of a workflow is proposed for GSO. The proposed FAST pattern includes a mechanism that actively pushes the latest status to clients instantly and economically. An independent proxy was designed to isolate the status tracking logic from the geoprocessing business logic, which assists the formation of a clear GSO workflow structure. A workflow was implemented in the FAST pattern to simulate the flooding process in the Poyang Lake region. Experimental results show that the proposed FAST pattern can efficiently tackle data/computing intensive geoprocessing tasks. The performance of all collaborative partners was improved due to the asynchronous mechanism throughout communication tier. A status-tracking mechanism helps users retrieve the latest running status of a GSO workflow in an efficient and instant way. The clear structure of the GSO workflow lowers the barriers for geospatial domain experts and model designers to
Full Text Available Migration has always played an important and determinative role in the formation of the Greek life-cycle, since the existence of a Greek Diaspora originates back to the institution of the Greek nation. However, whether the migration phenomenon represents a typical and integral part of the Greek cultural tradition or mentality, or appears as a forced consequence of specific economic or political circumstances, it should be pointed out that it has proved to be a transformative factor for the lives of people involved in it. The fate of "metanastes" (immigrants and the life in "xenitia" (foreign host land appear to be a very common and prominent topic elaborated in the poetic texts of the Greek "dimotika tragoudia" (traditional songs and "laika tragoudia" (folk-popular songs. Through these repertoires, music reveals its power in conveying and symbolically communicating and expressing public notions, feelings and cultural messages that acquire a particular significance for immigrant communities. Furthermore, diasporic music—along with dance—constitutes one of the basic components of the immigrant's cultural heritage, representing: an expressive way of maintaining cultural identity; a fixed, however metaphorical, conjunctional link between the mother country and the host land; and, a fundamental context through which the migratory community identifies or reconstitutes itself in relation to the majority and other surrounding groups. The author uses fieldwork from a year spent amongst Greek immigrant communities in the Stuttgart region of Germany to address and reflect on issues around the role of music in identity construction and the way in which this connects with processes of integration, assimilation and transnationalism. Specifically, the paper explores the multiple identities and repertories of a Greek musician in Germany, by focusing on several aspects of the musician's life-portrait and providing both emic and etic interpretations.

Full Text Available The article explores the complementary connections between communities of practice and the ways in which individuals orchestrate their engagement with others to further their professional learning. It does so by reporting on part of a research project conducted in New Zealand on teachers’ online professional learning in a university graduate diploma program on ICT education. Evolving from social constructivist pedagogy for online professional development, the research describes how teachers create their own networks of practice as they blend online and offline interactions with fellow learners and workplace colleagues. Teachers’ perspectives of their professional learning activities challenge the way universities design formal online learning communities and highlight the potential for networked learning in the zones and intersections between professional practice and study.The article extends the concepts of Lave and Wenger’s (1991 communities of practice social theory of learning by considering the role participants play in determining their engagement and connections in and across boundaries between online learning communities and professional practice. It provides insights into the applicability of connectivist concepts for developing online pedagogies to promote socially networked learning and for emphasising the role of the learner in defining their learning pathways.

Full Text Available The Musical Societies are the cultural agent that produces most musical events in Valencia, gathering around them the vast majorities of local amateur musicians, who are the main support that conforms them and at the same time leads its management. Its rise and proliferation has led to the growth and complexity of their structures, making it increasingly difficult operation with management based on volunteerism. In this study we analyzed each of the areas of Music Societies from the perspective of its managers in charge, aware of its management, and its musicians, who are aware of the real effects of it. Thus checking to what extent each structural framework needs an increasingly dedicated and expert figure, we also show to the Musical Societies some operating possibilities at their fingertips and finally we enable a self-analysis that objectively will assess the advantages of professionalism in management.

This study assessed the general health, music performance anxiety (MPA), and coping methods of musicians working in six state orchestras in Turkey. All musicians working in the state symphony orchestras (n=384) were invited to participate in the study. In face-to-face interviews, the authors administered a questionnaire, which consisted of five sections: sociodemographic information, history of musical performance, health status, general health questionnaire-12 (GHQ-12), and MPA scale. Mann-Whitney U-test, Student's t-test, and Spearman's correlation test were used to analyze the questionnaire data. The 220 musicians who participated included 121 (55%) males and 99 (45%) females, with a mean age of 42.4±11.3 yrs. For musculoskeletal symptoms, 87.6% reported at least one symptom with the most common being pain. For general health status, the GHQ-12 showed 64% of musicians were at low risk, 18.7% at moderate risk, and 17.3% at high risk in terms of mental health. The prevalence of MPA before or during performance was 81.8%, and 60% of musicians stated that performance anxiety negatively affected their performances. Results indicate that musicians working in Turkish state symphony orchestras encounter numerous health problems (tinnitus, hearing loss, musculoskeletal symptoms, etc.) due to their profession. No specific health support is provided, especially education and health service provision.

Language-music comparative studies have highlighted the potential for shared resources or neural overlap in auditory short-term memory. However, there is a lack of behavioral methodologies for comparing verbal and musical serial recall. We developed a visual grid response that allowed both musicians and nonmusicians to perform serial recall of letter and tone sequences. The new method was used to compare the phonological similarity effect with the impact of an operationalized musical equivalent-pitch proximity. Over the course of three experiments, we found that short-term memory for tones had several similarities to verbal memory, including limited capacity and a significant effect of pitch proximity in nonmusicians. Despite being vulnerable to phonological similarity when recalling letters, however, musicians showed no effect of pitch proximity, a result that we suggest might reflect strategy differences. Overall, the findings support a limited degree of correspondence in the way that verbal and musical sounds are processed in auditory short-term memory.

Playing an instrument often requires a certain posture and asymmetric position that may affect the anteroposterior spinal curvatures and may lead to postural asymmetry. The aim of the study was to evaluate the spinal curvatures in the sagittal plane and the magnitude of asymmetries in the trunk in the frontal plane in a group of music students in comparison with a control group. The group of 67 students aged 20 to 26 years was made up of 2 subgroups: the musicians (violin playing students of the Academy of Music in Wroclaw) and the control group (physical therapy students who played no instruments). The examination included an interview, measuring of somatic characteristics, and evaluation of body posture by means of the photogrammetric method. The spinal curvatures of the instrumentalists in the sagittal plane differ from the control group mainly in terms of length and depth parameters. Compared with the control group, the musicians were characterized by statistically more significantly longer and deeper thoracic kyphosis (P < .01) and more shallow lumbar lordosis (P < .05), a greater angle of thoracic kyphosis (P < .005), and a smaller inclination angle of the thoracolumbar and lumbosacral section of the spine (P < .01). In the group of musicians, the asymmetries in the area of shoulders and waist triangles as well as the distance of the spinous processes from the C7 to S1 line were more frequent.

The proposed Europa Mission concept contains many engineering and scientific instruments that consume varying amounts of power and produce varying amounts of data throughout the mission. System-level power and data usage must be well understood and analyzed to verify design requirements. Numerous cross-disciplinary tools and analysis models are used to simulate the system-level spacecraft power and data behavior. This paper addresses the problem of orchestrating a consistent set of models, tools, and data in a unified analysis toolchain when ownership is distributed among numerous domain experts. An analysis and simulation environment was developed as a way to manage the complexity of the power and data analysis toolchain and to reduce the simulation turnaround time. A system model data repository is used as the trusted store of high-level inputs and results while other remote servers are used for archival of larger data sets and for analysis tool execution. Simulation data passes through numerous domain-specific analysis tools and end-to-end simulation execution is enabled through a web-based tool. The use of a cloud-based service facilitates coordination among distributed developers and enables scalable computation and storage needs, and ensures a consistent execution environment. Configuration management is emphasized to maintain traceability between current and historical simulation runs and their corresponding versions of models, tools and data.

Full Text Available Inflammation has been known as one of the main keys to the establishment and progression of cancers. Chronic low-grade inflammation is also a strategic condition that underlies the causes and development of metabolic syndrome and obesity. Moreover, obesity has been largely related to poor prognosis of tumors by modulating tumor microenvironment with secretion of several inflammatory mediators by tumor-associated adipocytes (TAAs, which can modulate and recruit tumor-associated macrophages. Thus, the understanding of cellular and molecular mechanisms that underlay and link inflammation, obesity, and cancer is crucial to identify potential targets that interfere with this important route. Knowledge about the exact role of each component of the tumor microenvironment is not yet fully understood, but the new insights in literature highlight the essential role of adipocytes and macrophages interplay as key factor to determine the fate of cancer progression. In this review article, we focus on the functions of adipocytes and macrophages orchestrating cellular and molecular mechanisms that lead to inflammatory modulation in tumor microenvironment, which will be crucial to cancer establishment. We also emphasized the mechanisms by which the tumor promotes itself by recruiting and polarizing macrophages, discussing the role of adipocytes in this process. In addition, we discuss here the newest possible anticancer therapeutic treatments aiming to retard the development of the tumor based on what is known about cancer, adipocyte, and macrophage polarization.

Sensitization to inhaled allergens is dependent on activation of conventional dendritic cells (cDCs) and on the adaptor molecule, MyD88. However, many cell types in the lung express Myd88, and it is unclear how signaling in these different cell types reprograms cDCs and leads to allergic inflammation of the airway. By combining ATAC-seq with RNA profiling, we found that MyD88 signaling in cDCs maintained open chromatin at select loci even at steady state, allowing genes to be rapidly induced during allergic sensitization. A distinct set of genes related to metabolism was indirectly controlled in cDCs through MyD88 signaling in airway epithelial cells (ECs). In mouse models of asthma, Myd88 expression in ECs was critical for eosinophilic inflammation, whereas Myd88 expression in cDCs was required for Th17 cell differentiation and consequent airway neutrophilia. Thus, both cell-intrinsic and cell-extrinsic MyD88 signaling controls gene expression in cDCs and orchestrates immune responses to inhaled allergens.
Full Text Available The integration of equipment and other devices built into industrial robot cells with modern Ethernet interface technologies and low-cost mass produced devices (such as vision systems, laser scanners, force torque-sensors, PLCs and PDAs etc. enables integrators to offer more powerful and smarter solutions. Nevertheless, the programming of all these devices efficiently requires very specific knowledge about them, such as their hardware architectures and specific programming languages as well as details about the system's low level communication protocols. To address these issues, this paper describes and analyses the Plug-and-Play architecture. This is one of the most interesting service-oriented architectures (SOAs available, which exhibits characteristics that are well adapted to industrial robotics cells. To validate their programming features and applicability, a test bed was specially designed. This provides a new graphical service orchestration which was implemented using Workflow Foundation 4 of .NET. The obtained results allowed us to verify that the use of integration schemes based on SOAs reduces the system integration time and is better adapted to industrial robotic cell system integrators.

Immunological synapses are specialized cell-cell contacts formed between T lymphocytes and antigen-presenting cells. They are induced upon antigen recognition and are crucial for T-cell activation and effector functions. The generation and function of immunological synapses depend on an active T-cell polarization process, which results from a finely orchestrated crosstalk between the antigen receptor signal transduction machinery, the actin and microtubule cytoskeletons, and controlled vesicle traffic. Although we understand how some of these particular events are regulated, we still lack knowledge on how these multiple cellular elements are harmonized to ensure appropriate T-cell responses. We discuss here our view on how T-cell receptor signal transduction initially commands cytoskeletal and vesicle traffic polarization, which in turn sets the immunological synapse molecular design that regulates T-cell activation. We also discuss how the human immunodeficiency virus (HIV-1) hijacks some of these processes impairing immunological synapse generation and function. © 2013 John Wiley & Sons A/S.

Secondary diversification of the antibody repertoire upon antigenic challenge, in the form of immunoglobulin heavy chain (IgH) class-switch recombination (CSR) endows mature, naïve B cells in peripheral lymphoid organs with a limitless ability to mount an optimal humoral immune response, thus expediting pathogen elimination. CSR replaces the default constant (CH) region exons (Cμ) of IgH with any of the downstream CH exons (Cγ, Cε, or Cα), thereby altering effector functions of the antibody molecule. This process depends on, and is orchestrated by, activation-induced deaminase (AID), a DNA cytidine deaminase that acts on single-stranded DNA exposed during transcription of switch (S) region sequences at the IgH locus. DNA lesions thus generated are processed by components of several general DNA repair pathways to drive CSR. Given that AID can instigate DNA lesions and genomic instability, stringent checks are imposed that constrain and restrict its mutagenic potential. In this review, we will discuss how AID expression and substrate specificity and activity is rigorously enforced at the transcriptional, post-transcriptional, post-translational, and epigenetic levels, and how the DNA-damage response is choreographed with precision to permit targeted activity while limiting bystander catastrophe.

Full Text Available Over the past decades, the dichotomy between innate and adaptive immune responses has largely dominated our understanding of immunology. Upon primary encounter with microbial pathogens, differentiation of adaptive immune cells into functional effectors usually takes several days or even longer, making them contribute to host protection only late during primary infection. However, once generated, antigen-experienced T lymphocytes can persist in the organism and constitute a pool of memory cells that mediate fast and effective protection to a recall infection with the same microbial pathogen. Herein, we challenge this classical paradigm by highlighting the "innate nature" of memory CD8+ T cells. First, within the thymus or in the periphery, naïve CD8+ T cells may acquire phenotypic and functional characteristics of memory CD8+ T cells independently of challenge with foreign antigens. Second, both the "unconventional" and the "conventional" memory cells can rapidly express protective effector functions in response to sets of inflammatory cytokines and chemokines signals, independent of cognate antigen triggering. Third, memory CD8+ T cells can act by orchestrating the recruitment, activation, and licensing of innate cells, leading to broad antimicrobial states. Thus, collectively, memory CD8+ T cells may represent important actors of innate immune defenses.

Full Text Available Signed in 1974, the Sonata for violin and piano by Viorel Munteanu continues the Enescu tradition and distinguishes itself by an original musical language, that alongside of the form sobriety, places this opus among the most representative examples of Romanian chamber instrumental music of the second half of the 20th century. Special attention is given to the exploration of the source of folklore and the Byzantine influence that generate the intonational-thematic structure of the whole work and relate it to the opuses of Moldovan music. Thus, the abundance of sound symbols and specific elements of the „pastoral” space reveals essential aspects of the interpretative conception of the native musicians. This composition was premiered in Chisinau within the framework of the 25th edition of the International Festival The Days of New Music. In the present article the author wants to pay her respects to the late violinist Angela Molodojan who performed with remarkable artistry, originality and musical refinement the violin part in the above-mentioned creation.

The purpose of this investigation was to assess the effects of earplugs on acoustical and perceptual measures of choral and solo sound. The researcher tested the effects of musician's earplugs on choral and solo timbre and singer perceptions. Members of an intact women's university choir recorded Dona Nobis Pacem under two conditions, no earplugs and with earplugs over time. Approximately half of the choir members also participated as soloists, recording Over the Rainbow under the same two conditions. All recordings were analyzed using long-term average spectra (LTAS). After participating in each recording session, the participants responded to a questionnaire about ability to hear self (solo and choral context) and ability to hear others (choral context) under two conditions, no earplugs and with earplugs. LTAS results revealed that wearing earplugs in a choral setting caused decreased mean signal energy (>1 dB), resulting in less resonant singing. LTAS results also indicated that wearing earplugs in a solo setting had less effect on mean signal energy, resulting in a mean difference solo setting. Findings from this study could provide important information when structuring hearing conservation strategies. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.
Full Text Available The combined influence of tempo and mode on emotional responses to music was studied by crossing 7 changes in mode with 3 changes in tempo. Twenty-four musicians aged 19 to 25 years (12 males and 12 females and 24 nonmusicians aged 17 to 25 years (12 males and 12 females were required to perform two tasks: 1 listening to different musical excerpts, and 2 associating an emotion to them such as happiness, serenity, fear, anger, or sadness. ANOVA showed that increasing the tempo strongly affected the arousal (F(2,116 = 268.62, mean square error (MSE = 0.6676, P < 0.001 and, to a lesser extent, the valence of emotional responses (F(6,348 = 8.71, MSE = 0.6196, P < 0.001. Changes in modes modulated the affective valence of the perceived emotions (F(6,348 = 4.24, MSE = 0.6764, P < 0.001. Some interactive effects were found between tempo and mode (F (1,58 = 115.6, MSE = 0.6428, P < 0.001, but, in most cases, the two parameters had additive effects. This finding demonstrates that small changes in the pitch structures of modes modulate the emotions associated with the pieces, confirming the cognitive foundation of emotional responses to music.

ído ambiental incômodo e presença de zumbido.PURPOSE: To identify the presence of hyperacusis and to investigate the characteristics of uncomfortable sounds, as well as the behaviors triggered by the discomfort in musicians of a Military Band. METHODS: Twenty seven musicians of the Military Band of the Santa Maria Airbase (RS were studied. Their ages ranged from 22 to 50 years old and military work time from four to 26 years, with daily occupational noise exposure time from two to eight hours. All subjects were submitted to a basic audiological evaluation, sound discomfort threshold test and application of a questionnaire. It was considered presence of hyperacusis when the average of the obtained values on the discomfort threshold in 250, 500, 1000, 2000, 4000 Hertz was less than or equal to 90 decibels, associated with hearing discomfort complaint. RESULTS: It was verified presence of hyperacusis in 37% of the musicians. From these, 50% presented normal hearing and 50% had normal hearing with notch; 80% of them felt the discomfort daily and 20% only after band practice; 70% of the musicians had already avoided some activities, believing that the activity noise would be distressing; 70% of them used ear plugs regularly and 90% referred presence of tinnitus. The sounds that were considered to be distressing by hyperacusics were, predominantly, high intensity sounds. The most common emotional responses towards a distressing sound were tension, anxiety and the urge of repelling from it. CONCLUSION: According to the criteria used in this study, 37% of the studied individuals were classified as hyperacusics, which considered predominantly high intensity sounds to be unpleasant. The main emotional responses before these sounds were: tension, anxiety and the need to repel from the sound. The common characteristics among the subjects classified as hyperacusics were: normal hearing, use of ear plugs, avoidance of activities fearing the discomfort caused by the noise, and the presence

On the basis of previous results showing that music training positively influences different aspects of speech perception and cognition, the aim of this series of experiments was to test the hypothesis that adult professional musicians would learn the meaning of novel words through picture-word associations more efficiently than controls without music training (i.e., fewer errors and faster RTs). We also expected musicians to show faster changes in brain electrical activity than controls, in particular regarding the N400 component that develops with word learning. In line with these hypotheses, musicians outperformed controls in the most difficult semantic task. Moreover, although a frontally distributed N400 component developed in both groups of participants after only a few minutes of novel word learning, in musicians this frontal distribution rapidly shifted to parietal scalp sites, as typically found for the N400 elicited by known words. Finally, musicians showed evidence for better long-term memory for novel words 5 months after the main experimental session. Results are discussed in terms of cascading effects from enhanced perception to memory as well as in terms of multifaceted improvements of cognitive processing due to music training. To our knowledge, this is the first report showing that music training influences semantic aspects of language processing in adults. These results open new perspectives for education in showing that early music training can facilitate later foreign language learning. Moreover, the design used in the present experiment can help to specify the stages of word learning that are impaired in children and adults with word learning difficulties.

Metalloenzymes catalyze complex and essential processes, such as photosynthesis, respiration, and nitrogen fixation. For example, bacteria and archaea use [NiFe]-hydrogenases to catalyze the uptake and release of molecular hydrogen (H 2 ). [NiFe]-hydrogenases are redox enzymes composed of a large subunit that harbors a NiFe(CN) 2 CO metallo-center and a small subunit with three iron-sulfur clusters. The large subunit is synthesized with a C-terminal extension, cleaved off by a specific endopeptidase during maturation. The exact role of the C-terminal extension has remained elusive; however, cleavage takes place exclusively after assembly of the [NiFe]-cofactor and before large and small subunits form the catalytically active heterodimer. To unravel the functional role of the C-terminal extension, we used an enzymatic in vitro maturation assay that allows synthesizing functional [NiFe]-hydrogenase-2 of Escherichia coli from purified components. The maturation process included formation and insertion of the NiFe(CN) 2 CO cofactor into the large subunit, endoproteolytic cleavage of the C-terminal extension, and dimerization with the small subunit. Biochemical and spectroscopic analysis indicated that the C-terminal extension of the large subunit is essential for recognition by the maturation machinery. Only upon completion of cofactor insertion was removal of the C-terminal extension observed. Our results indicate that endoproteolytic cleavage is a central checkpoint in the maturation process. Here, cleavage temporally orchestrates cofactor insertion and protein assembly and ensures that only cofactor-containing protein can continue along the assembly line toward functional [NiFe]-hydrogenase. © 2017 by The American Society for Biochemistry and Molecular Biology, Inc.

Musicians face numerous psychosocial and physical demands at work resulting in high prevalence of musculoskeletal problems. Unlike physical risks, little is known about psychosocial work factors influencing such health problems in this particular group. The paper aimed to identify psychosocial work demands resulting in musculoskeletal problems among musicians. A systematic review was undertaken to find data linking psychosocial work demands or stress with musculoskeletal disorders among musicians. The exploration of databases resulted in nine research studies linking psychosocial aspects of work or stress with musculoskeletal problems among musicians. The analyzed studies linked psychosocial aspects with musculoskeletal problems in three ways - showing proportions of people indicating particular causes of pain, indicating correlations between these variables or performing regression analysis showing psychosocial predictors of musculoskeletal pain. Only a few studies have undertaken the issue of psychosocial risk factors for musculoskeletal problems among musicians. The results revealed that some psychosocial aspects of work, e.g. long hours at work, work content, high job demands, low control/influence, lack of social support, were related to musculoskeletal pain, however, the methods and results were inconsistent. The extant studies employed variety of definitions of psychosocial aspects that hindered the possibility for consistent conclusions. Basing on those conclusions, future directions were offered.

Professional autonomy may represent the first step to implementing measures that will allow CRNAs to attain a level of independent practice consistent with their clinical and educational training. Autonomy is regarded as an essential ingredient of professionalism and confers independent function at the individual practitioner level. The principle of autonomy refers to the individual's capacity to make independent decisions based on the assumption that he or she possesses the cognitive, psychological, and emotional faculties to make rational decisions. Nursing practice meets the first two criteria of professionalism--competence and dedication to an important social good. The third criterion of professionalism, autonomy, has been a focal point for controversy since the late nineteenth century, in which obedience to supervisors and physicians remained a central focus of nursing ethics teaching until the advent of feminism in the 1970s. This article presents a thorough analysis of these concepts with some thoughts on how understanding the fundamental precepts and further research may not only help maintain the current level of CRNA professional autonomy but serve to guide us to become more autonomous in the future.

THREDDS is a widely used web server to provide to different scientific communities with data access and discovery. Due to THREDDS's lack of horizontal scalability and automatic configuration management and deployment, this service usually deals with service downtimes and time consuming configuration tasks, mainly when an intensive use is done as is usual within the scientific community (e.g. climate). Instead of the typical installation and configuration of a single or multiple independent THREDDS servers, manually configured, this work presents an automatic provisioning, deployment and orchestration cluster of THREDDS servers. This solution it's based on Ansible playbooks, used to control automatically the deployment and configuration setup on a infrastructure and to manage the datasets available in THREDDS instances. The playbooks are based on modules (or roles) of different backends and frontends load-balancing setups and solutions. The frontend load-balancing system enables horizontal scalability by delegating requests to backend workers, consisting in a variable number of instances for the THREDDS server. This implementation allows to configure different infrastructure and deployment scenario setups, as more workers are easily added to the cluster by simply declaring them as Ansible variables and executing the playbooks, and also provides fault-tolerance and better reliability since if any of the workers fail another instance of the cluster can take over it. In order to test the solution proposed, two real scenarios are analyzed in this contribution: The JASMIN Group Workspaces at CEDA and the User Data Gateway (UDG) at the Data Climate Service from the University of Cantabria. On the one hand, the proposed configuration has provided CEDA with a higher level and more scalable Group Workspaces (GWS) service than the previous one based on Unix permissions, improving also the data discovery and data access experience. On the other hand, the UDG has improved its
Full Text Available O artigo relata estudo sobre a profissão dos músicos na Paraíba, realizado por meio da aplicação da análise de conteúdo de dois jornais diários do Estado. A referida análise foi desenvolvida com uma amostra de números referentes aos anos de 2001 e 2003. Identificaram-se quatro categorias (papel social da música; incentivo à música; profissão e organização político-associativas. Tal estudo empírico resultou na identificação de aspectos centrais e importantes na construção da identidade profissional, como: o profissionalismo versus amadorismo; o mito da fama versus o anonimato; desvalorização da chamada prata da casa versus valorização do estrangeiro, etc. Embora não esgotem o tema, situam o lugar que a profissão ocupa na sociedade e pode se constituir em fonte para a elaboração de novas questões e hipóteses para os pesquisadores que se interessarem pela temática.The article reports study on the profession of musicians in the State of Paraíba, conducted by applying the analysis of contents of two daily newspapers of the State. The analysis itself was developed with a sample of issues of the years 2001 and 2003. Four categories were identified (social role of the music; encouraging the music; profession and associative political organization. Such empirical study resulted in the identification of key and important aspects, in the construction of a professional identity, as, professionalism versus amateurism; the myth of fame versus the anonymity; the depreciation of the so-called home talent versus the value of the foreign ones, and so on. Even though this type of media does not exhaust the subject, it establishes the position that the profession occupies in the society and may constitute itself a source for the development of new questions and hypotheses for the researchers interested in the topic.

Full Text Available The article presents information organized in chronological order on the professional and personal contacts of M. Cebotari with R. Strauss in the last seven years of their lives (1942–1949. The development of military events during the war, as well as the advanced age of the maestro partially stopped relations between the two musicians. This period shows the fact that M. Cebotari not only maintained her interest in Straus`s vocal music, but also began to perform in new roles, adding to her repertoire the dramatic soprano parts. The article is well supported with quotes of the contemporaries, and with reviews from the newspapers of that time.

Pitch-height is often labeled spatially (i.e., low or high) as a function of the fundamental frequency of the tone. This correspondence is highlighted by the so-called Spatial-Musical Association of Response Codes (SMARC) effect. However, the literature suggests that the brightness of the tone's timbre might contribute to this spatial association. We investigated the SMARC effect in a group of non-musicians by disentangling the role of pitch-height and the role of tone-brightness. In three experimental conditions, participants were asked to judge whether the tone they were listening to was (or was not) modulated in amplitude (i.e., vibrato). Participants were required to make their response in both the horizontal and the vertical axes. In a first condition, tones varied coherently in pitch (i.e., manipulation of the tone's F0) and brightness (i.e., manipulation of the tone's spectral centroid); in a second condition, pitch-height varied whereas brightness was fixed; in a third condition, pitch-height was fixed whereas brightness varied. We found the SMARC effect only in the first condition and only in the vertical axis. In contrast, we did not observe the effect in any of the remaining conditions. The present results suggest that, in non-musicians, the SMARC effect is not due to the manipulation of the pitch-height alone, but arises because of a coherent change of pitch-height and brightness; this effect emerges along the vertical axis only.
Full Text Available Motor neurons in the spinal cord are found grouped in nuclear structures termed pools, whose position is precisely orchestrated during development. Despite the emerging role of pool organization in the assembly of spinal circuits, little is known about the morphogenetic programs underlying the patterning of motor neuron subtypes. We applied three-dimensional analysis of motor neuron position to reveal the roles and contributions of cell adhesive function by inactivating N-cadherin, catenin, and afadin signaling. Our findings reveal that nuclear organization of motor neurons is dependent on inside-out positioning, orchestrated by N-cadherin, catenin, and afadin activities, controlling cell body layering on the medio-lateral axis. In addition to this lamination-like program, motor neurons undergo a secondary, independent phase of organization. This process results in segregation of motor neurons along the dorso-ventral axis of the spinal cord, does not require N-cadherin or afadin activity, and can proceed even when medio-lateral positioning is perturbed.

The purpose of the first session was to help mid-career physicists aspire for and achieve leadership roles. The second session brought together students, postdoctoral fellows, and early-career physicists to help them plan their career goals and navigate the steps important to launching a successful career. The final session sought to increase awareness of the results of physics education research, and how to use them to help students-especially women-learn physics better. The presentations and discussions were valuable for both female and male physicists.
Acoustics and the Performance of Music connects scientific understandings of acoustics with practical applications to musical performance. Of central importance are the tonal characteristics of musical instruments and the singing voice including detailed representations of directional characteristics. Furthermore, room acoustical concerns related to concert halls and opera houses are considered. Based on this, suggestions are made for musical performance. Included are seating arrangements within the orchestra and adaptations of performance techniques to the performance environment. In the presentation we dispense with complicated mathematical connections and deliberately aim for conceptual explanations accessible to musicians, particularly for conductors. The graphical representations of the directional dependence of sound radiation by musical instruments and the singing voice are unique. Since the first edition was published in 1978, this book has been completely revised and rewritten to include current rese...

The aim of a spatial data infrastructure (SDI) is to make data available for the economical and societal benefit to a wide audience. A geoportal typically provides access to spatial data and associated web services in an SDI, facilitating the discovery, display, editing and analysis of data. In contrast, a spatial information infrastructure (SII) should provide access to information, i.e. data that has been processed, organized and presented so as to be useful. Thematic maps are an example of the representation of spatial information. An SII geoportal requires intelligence to orchestrate (automatically coordinate) web services that prepare, discover and present information, instead of data, to the user. We call this an intelligent geoportal. The Open Geospatial Consortium's Web Processing Service (WPS) standard provides the rules for describing the input and output of any type of spatial process. In this paper we present the results of an evaluation of two orchestration platforms: the 52° North framework and ZOO project. We evaluated the frameworks' orchestration capabilities for producing thematic maps. Results of the evaluation show that both frameworks have potential to facilitate orchestration in an intelligent geoportal, but that some functionality is still lacking; lack of semantic information and usability of the framework; these limitations creates barriers for the wide spread use of the frameworks. Before, the frameworks can be used for advance orchestration these limitations need to be addressed. The results of our evaluation of these frameworks, both with their respective strengths and weaknesses, can guide developers to choose the framework best suitable for their specific needs.

Full Text Available This study had the purpose of determining the frequency of musculoskeletal symptoms in musicians of the Symphonic Orchestra of the State University of Londrina. 45 musicians took part in this study answering a self-administered questionnaire with the following aspects: personal data, job-factor survey, symptom related to work, treatment and its consequences. As for the analysis of the variables the quisquare Test was used with Yates correction and the Test of Fisher. Of the 45 musicians studied, 82,2% were men and with an average age of 39,56 years old. Of all the researched musicians, 77,8% reported the presence of musculoskeletal symptoms during the last twelve months and 71,1% in the last seven days. The highest prevalence was in the following anatomical areas: shoulders, neck, spine, hands and wrists. The present study found a high prevalence of musculoskeletal symptoms in musicians who play string and wind instruments. Due to the symptoms, 33,3% of the professionals lost days of work. The present study found a high prevalence of musculoskeletal symptoms not only during the last twelve months but also during the last seven days that preceded the answering of the questionnaire, mainly in the spine and shoulders area. These symptoms can be related to physical and emotional loads. Taking the results into account, the elaboration and implantation of strategies to soften the workload and to avoid disorders are necessary.

Full Text Available Job stress is a line, for the person at work hired adverse physiological, psychological and behavioral reactions to situations in which job requirements are not in accordance with its capabilities, abilities and needs. Sources of stress at work are numerous. Personal factors: personality types have been most studied so far, environmental changes and demographic characteristics as well. Interpersonal stress inducing factors act and influence to the occurrence of many psychosomatic diseases. Psychosocial climate and relationships which are prevented or encouraged such as: cooperation and competition, trust and suspicion certainly affect to the appearance of professional stress. The way of leadership is very important. Organizational factors are the type of work, work time, noncompliance of the job, the introduction of new ethnologies, the conflict of personal roles, fear of job loss, bad physical conditions of working environment. The consequences of stress at work are numerous: at the cognitive level, the emotional level, the production plan, the health, plan reduces the immune system that cause a variety of psychosomatic illnesses and accidents at work.
Most medical photographers, unless working as dedicated ophthalmic photographers or retinal screeners, will shoot portraits or publicity pictures. Many will spend a proportion of their time producing brochure shots for patient information material or their Trust's Annual Report. High-quality images of staff at work are often required by the strategic planning departments of Trusts to support bids for business from service commissioners. This "non-clinical" work is in reality commercial work - the jobs that high street portrait and general practice photographers would undertake in different settings. Medical photographers use many of the same tools as their commercial cousins. They use the same DSLR cameras and lenses. They use Adobe Photoshop to manipulate images. However, one software tool extensively used by portrait and social photographers, but possibly unfamiliar to many medical photographers, is Portrait Professional. Currently in its 10th version, it is produced by Anthropics Technology ( http://www.anthropics.com ), a London-based company specialising in image manipulation software.
Full Text Available PBL is learning through becoming conscious of practical and abstract problems and finding ways how to solve them. It can be a pattern which doesn’t follow traditional divisions of disciplines. In this article the material was collected from two, in the first sight, very different groups. One was music students (N = 62 who had to learn to solve various practical and theoretical problems in preparing a program for a series of concerts as collective and individual action. The method used was the 7-step method which divides learning into seven phases proceeding from creating the social frame of reference and mental models (steps 1–4 through actual work (steps 5–6 to the evaluation of the outcomes (step 7. Another group consisted of international, multicultural business leaders in engineering (N = 6. In using earlier the 7-step method, the approaches resembled those of the music students: deepening their professional competences. To engage their ability to use imagination and connect reality with brainstorming and mental flexibility, the creative PBL method 635 was used. Three practical problems were solved so that the solutions included new viewpoints which would be applied to meet the real needs in the near future. The results show that not only were the learning targets of both groups reached but, with reflection included, the processes widened the professional competences of the participants.

Psychophysiological evidence suggests that music and language are intimately coupled such that experience/training in one domain can influence processing required in the other domain. While the influence of music on language processing is now well-documented, evidence of language-to-music effects have yet to be firmly established. Here, using a cross-sectional design, we compared the performance of musicians to that of tone-language (Cantonese) speakers on tasks of auditory pitch acuity, music perception, and general cognitive ability (e.g., fluid intelligence, working memory). While musicians demonstrated superior performance on all auditory measures, comparable perceptual enhancements were observed for Cantonese participants, relative to English-speaking nonmusicians. These results provide evidence that tone-language background is associated with higher auditory perceptual performance for music listening. Musicians and Cantonese speakers also showed superior working memory capacity relative to nonmusician controls, suggesting that in addition to basic perceptual enhancements, tone-language background and music training might also be associated with enhanced general cognitive abilities. Our findings support the notion that tone language speakers and musically trained individuals have higher performance than English-speaking listeners for the perceptual-cognitive processing necessary for basic auditory as well as complex music perception. These results illustrate bidirectional influences between the domains of music and language.

Direct-write nanomanufacturing with scanning beams and probes is flexible and can produce high quality products, but it is normally slow and expensive to raster point-by-point over a pattern. We demonstrate the use of an accelerated direct-write nanomanufacturing method called 'orchestrated structure evolution' (OSE), where a direct-write tool patterns a small number of growth 'seeds' that subsequently grow into the final thin film pattern. Through control of seed size and spacing, it is possible to vary the ratio of 'top-down' to 'bottom-up' character of the patterning processes, ranging from conventional top-down raster patterning to nearly pure bottom-up space-filling via seed growth. Electron beam lithography (EBL) and copper electrodeposition were used to demonstrate trade-offs between process time and product quality over nano- to microlength scales. OSE can reduce process times for high-cost EBL patterning by orders of magnitude, at the expense of longer (but inexpensive) copper electrodeposition processing times. We quantify the degradation of pattern quality that accompanies fast OSE patterning by measuring deviations from the desired patterned area and perimeter. We also show that the density of OSE-induced grain boundaries depends upon the seed separation and size. As the seed size is reduced, the uniformity of an OSE film becomes more dependent on details of seed nucleation processes than normally seen for conventionally patterned films.

We investigated the relationships of the two immune-regulatory plant metabolites, salicylic acid (SA) and pipecolic acid (Pip), in the establishment of plant systemic acquired resistance (SAR), SAR-associated defense priming, and basal immunity. Using SA-deficient sid2, Pip-deficient ald1, and sid2 ald1 plants deficient in both SA and Pip, we show that SA and Pip act both independently from each other and synergistically in Arabidopsis thaliana basal immunity to Pseudomonas syringae. Transcriptome analyses reveal that SAR establishment in Arabidopsis is characterized by a strong transcriptional response systemically induced in the foliage that prepares plants for future pathogen attack by preactivating multiple stages of defense signaling and that SA accumulation upon SAR activation leads to the downregulation of photosynthesis and attenuated jasmonate responses systemically within the plant. Whereas systemic Pip elevations are indispensable for SAR and necessary for virtually the whole transcriptional SAR response, a moderate but significant SA-independent component of SAR activation and SAR gene expression is revealed. During SAR, Pip orchestrates SA-dependent and SA-independent priming of pathogen responses in a FLAVIN-DEPENDENT-MONOOXYGENASE1 (FMO1)-dependent manner. We conclude that a Pip/FMO1 signaling module acts as an indispensable switch for the activation of SAR and associated defense priming events and that SA amplifies Pip-triggered responses to different degrees in the distal tissue of SAR-activated plants. © 2016 American Society of Plant Biologists.

Engraftment of transplanted cells is critical for liver-directed cell therapy but most transplanted cells are rapidly cleared from liver sinusoids by proinflammatory cytokines/chemokines/receptors after activation of neutrophils or Kupffer cells. To define whether TNF-α served roles in cell-transplantation-induced hepatic inflammation, we used TNF-α antagonist, etanercept, for studies in syngeneic rat hepatocyte transplantation systems. After cell transplantation, multiple cytokines/chemokines/receptors were overexpressed, whereas etanercept prior to cell transplantation essentially normalized these responses. Moreover, ETN downregulated cell transplantation-induced intrahepatic release of secretory cytokines, such as high mobility group box 1. These effects of etanercept decreased cell transplantation-induced activation of neutrophils but not of Kupffer cells. Transplanted cell engraftment improved by several-fold in etanercept-treated animals. These gains in cell engraftment were repeatedly realized after pretreatment of animals with etanercept before multiple cell transplantation sessions. Transplanted cell numbers did not change over time indicating absence of cell proliferation after etanercept alone. By contrast, in animals preconditioned with retrorsine and partial hepatectomy, cell transplantation after etanercept pretreatment significantly accelerated liver repopulation compared with control rats. We concluded that TNF-α played a major role in orchestrating cell transplantation-induced inflammation through regulation of multiple cytokines/chemokines/receptor expression. As TNF-α antagonism by etanercept decreased transplanted cell clearance, improved cell engraftment and accelerated liver repopulation, this pharmacological approach to control hepatic inflammation will help optimize clinical strategies for liver cell therapy.

We analysed the effect of photoperiod length (PPL) (16:8 and 8:16 h of light-dark regime, named long and short PPL, respectively) on the temporal orchestration of the two antagonistic, carbon and nitrogen acquisitions in the unicellular, diazotrophic cyanobacterium Crocosphaera watsonii strain WH8501 growing diazotrophically. Carbon and nitrogen metabolism were monitored at high frequency, and their patterns were compared with the cell cycle progression. The oxygen-sensitive N2 fixation process occurred mainly during the dark period, where photosynthesis cannot take place, inducing a light-dark cycle of cellular C : N ratio. Examination of circadian patterns in the cell cycle revealed that cell division occurred during the midlight period, (8 h and 4 h into the light in the long and short PPL conditions, respectively), thus timely separated from the energy-intensive diazotrophic process. Results consistently show a nearly 5 h time lag between the end of cell division and the onset of N2 fixation. Shorter PPLs affected DNA compaction of C. watsonii cells and also led to a decrease in the cell division rate. Therefore, PPL paces the growth of C. watsonii: a long PPL enhances cell division while a short PPL favours somatic growth (biomass production) with higher carbon and nitrogen cell contents. © 2013 Society for Applied Microbiology and John Wiley & Sons Ltd.
Full Text Available Zebrafish regenerate their fins via the formation of a population of progenitor cells, the blastema. Wnt/β-catenin signaling is essential for blastemal cell proliferation and patterning of the overlying epidermis. Yet, we find that β-catenin signaling is neither active in the epidermis nor the majority of the proliferative blastemal cells. Rather, tissue-specific pathway interference indicates that Wnt signaling in the nonproliferative distal blastema is required for cell proliferation in the proximal blastema, and signaling in cells lining the osteoblasts directs osteoblast differentiation. Thus, Wnt signaling regulates epidermal patterning, blastemal cell proliferation, and osteoblast maturation indirectly via secondary signals. Gene expression profiling, chromatin immunoprecipitation, and functional rescue experiments suggest that Wnt/β-catenin signaling acts through Fgf and Bmp signaling to control epidermal patterning, whereas retinoic acid and Hedgehog signals mediate its effects on blastemal cell proliferation. We propose that Wnt signaling orchestrates fin regeneration by defining organizing centers that instruct cellular behaviors of adjacent tissues.

Calcineurin plays essential roles in virulence and growth of pathogenic fungi and is a target of the natural products FK506 and Cyclosporine A. In the pathogenic mucoralean fungus Mucor circinelloides, calcineurin mutation or inhibition confers a yeast-locked phenotype indicating that calcineurin governs the dimorphic transition. Genetic analysis in this study reveals that two calcineurin A catalytic subunits (out of three) are functionally diverged. Homology modeling illustrates modes of resistance resulting from amino substitutions in the interface between each calcineurin subunit and the inhibitory drugs. In addition, we show how the dimorphic transition orchestrated by calcineurin programs different outcomes during host-pathogen interactions. For example, when macrophages phagocytose Mucor yeast, subsequent phagosomal maturation occurs, indicating host cells respond appropriately to control the pathogen. On the other hand, upon phagocytosis of spores, macrophages fail to form mature phagosomes. Cytokine production from immune cells differs following exposure to yeast versus spores (which germinate into hyphae). Thus, the morphogenic transition can be targeted as an efficient treatment option against Mucor infection. In addition, genetic analysis (including gene disruption and mutational studies) further strengthens the understanding of calcineurin and provides a foundation to develop antifungal agents targeting calcineurin to deploy against Mucor and other pathogenic fungi. © 2015 John Wiley & Sons Ltd.
Full Text Available This paper proposes a virtualized network function orchestration system based on Network Function Virtualization (NFV, one of the main technologies in 5G mobile networks. This system should provide connectivity between network devices and be able to create flexible network function and distribution. This system focuses more on access networks. By experimenting with various scenarios of user service established and activated in a network, we examine whether rapid adoption of new service is possible and whether network resources can be managed efficiently. The proposed method is based on Bluetooth transfer technology and mesh networking to provide automatic connections between network machines and on a Docker flat form, which is a container virtualization technology for setting and managing key functions. Additionally, the system includes a clustering and recovery measure regarding network function based on the Docker platform. We will briefly introduce the QR code perceived service as a user service to examine the proposal and based on this given service, we evaluate the function of the proposal and present analysis. Through the proposed approach, container relocation has been implemented according to a network device’s CPU usage and we confirm successful service through function evaluation on a real test bed. We estimate QR code recognition speed as the amount of network equipment is gradually increased, improving user service and confirm that the speed of recognition is increased as the assigned number of network devices is increased by the user service.

Starch and fructan are two important carbohydrates in many flowering plants and in human diets. Understanding how plants allocate photosynthates and how they prioritize synthesis of different carbohydrates during development is essential in efforts to improve cereals for increased stress tolerance and for desirable carbohydrate compositions in food and feed. We report the coordinated synthesis of starch and fructan in barley, orchestrated by two functionally opposing transcription factors encoded from two alternative promoters, one intronic/exonic, harbored on a single gene. . This dual-transcription factor system employs an autoregulatory, antagonsitic mechanism in sensing sucrose at one promoter, potentially via sucrose/glucose/fructose/trehalose 6-phosphate signaling, and conduct a coordinated synthesis of starch and fructan synthesis by competitive transcription factor binding to the second promoter The finding of an intron/exon-spanning promoter in a hosting gene, resulting in proteins with distinct functions, contributes to our appreciation of the complexity of the plant genome As a case in point for the physiological role of the antagonistic transcription factor system, we have demonstrated that it can be exploited in breeding barley with tailored amounts of fructan for production of specialty food ingredients.

Full Text Available Abstract Background The Kenny Music Performance Anxiety Inventory (K-MPAI is very significant among the available instruments which measures Musical Performance Anxiety (MPA. Objective The aim of this study is to find evidence of validity of the Kenny Music Performance Anxiety Inventory (K-MPAI, in its translated and adapted Brazilian version, through the study of its factor structure. Methods A convenience sample of 230 amateur musicians completed the K-MPAI. Results The initial factor analysis yielded eight factors, explaining 62.4% of variance. However, due to the factors’ composition and internal consistency values lower than 0.50, the number of factors was later set at three, considering the internal consistency of those, the theoretical propositions and symptomatology aspects that supported the construction of scale. They were named “Worries and insecurity” (α = 0.82, “Depression and hopelessness” (α = 0.77 and “Early parental relationships” (α = 0.57. Discussion/Conclusions These results point to the scale’s construct validity, since they support the theoretical basis used for the development of the K-MPAI and the clinical manifestations of the MPA.

This qualitative research investigates the alcohol experiences of entertainers who perform within licensed premises. Previous, mainly quantitative, studies have found that entertainers, specifically musicians, are an occupational group who drink excessively. This qualitative study draws on a wider sample of entertainers to examine their accounts of drinking in the workplace and the explanations they provide for this. We conducted individual semi-structured interviews (n=24) with band-members, variety acts and DJs in Glasgow, Scotland. This revealed a workplace characterised by continual opportunities for often free alcohol consumption. Unlike most occupations, for entertainers 'drinking-on-the-job' was normative, expected, and sometimes encouraged by peers, the public, employers or sponsors. Entertainers also experienced performance-related incentives to drink before, during and/or after a show; including anxiety, matching their intoxication level to the audience's, and 'reward-drinking'. This qualitative research confirms the unique nature of the entertainer-alcohol link, even in comparison to that found within other leisure industry occupations. While providing some explanation as to why entertainers might drink excessively, participants' accounts also suggested potential strategies for avoiding the negative outcomes of workplace drinking.

The clinical value of extended high-frequency audiometry for the detection of noise-induced hearing loss has not been established conclusively. The purpose of this study was to assess the relative temporary threshold shift (TTS) in two frequency regions (conventional versus extended high frequency). In this exploratory study, pure-tone thresholds from 0.5 to 14 kHz were measured in both ears of 16 nonprofessional pop/rock musicians (mean age, 35 yr; range, 27 to 49 yr), before and after a 90-minute rehearsal session. All had experienced repeated exposures to intense sound levels during at least 5 yr of their musical careers. After the rehearsal, median threshold levels were found to be significantly poorer for frequencies from 0.5 to 8 kHz (Wilcoxon signed rank test, p

Infectious retrovirus particles contain two copies of unspliced viral RNA that serve as the viral genome. Unspliced retroviral RNA is transcribed in the nucleus by the host RNA polymerase II and has three potential fates: (1) it can be spliced into subgenomic messenger RNAs (mRNAs) for the translation of viral proteins; or it can remain unspliced to serve as either (2) the mRNA for the translation of Gag and Gag–Pol; or (3) the genomic RNA (gRNA) that is packaged into virions. The Gag structural protein recognizes and binds the unspliced viral RNA to select it as a genome, which is selected in preference to spliced viral RNAs and cellular RNAs. In this review, we summarize the current state of understanding about how retroviral packaging is orchestrated within the cell and explore potential new mechanisms based on recent discoveries in the field. We discuss the cis-acting elements in the unspliced viral RNA and the properties of the Gag protein that are required for their interaction. In addition, we discuss the role of host factors in influencing the fate of the newly transcribed viral RNA, current models for how retroviruses distinguish unspliced viral mRNA from viral genomic RNA, and the possible subcellular sites of genomic RNA dimerization and selection by Gag. Although this review centers primarily on the wealth of data available for the alpharetrovirus Rous sarcoma virus, in which a discrete RNA packaging sequence has been identified, we have also summarized the cis- and trans-acting factors as well as the mechanisms governing gRNA packaging of other retroviruses for comparison.

Purpose: Radiation resistance induced in cancer cells that survive after radiation therapy (RT) could be associated with increased radiation protection, limiting the therapeutic benefit of radiation. Herein we investigated the sequential mechanistic molecular orchestration involved in radiation-induced radiation protection in tumor cells. Results: Radiation, both in the low-dose irradiation (LDIR) range (10, 50, or 100 cGy) or at a higher, challenge dose IR (CDIR), 4 Gy, induced dose-dependent and sustained NFκB-DNA binding activity. However, a robust and consistent increase was seen in CDIR-induced NFκB activity, decreased DNA fragmentation, apoptosis, and cytotoxicity and attenuation of CDIR-inhibited clonal expansion when the cells were primed with LDIR prior to challenge dose. Furthermore, NFκB manipulation studies with small interfering RNA (siRNA) silencing or p50/p65 overexpression unveiled the influence of LDIR-activated NFκB in regulating CDIR-induced DNA fragmentation and apoptosis. LDIR significantly increased the transactivation/translation of the radiation-responsive factors tumor necrosis factor-α (TNF-α), interleukin-1α (IL-1α), cMYC, and SOD2. Coculture experiments exhibit LDIR-influenced radiation protection and increases in cellular expression, secretion, and activation of radiation-responsive molecules in bystander cells. Individual gene-silencing approach with siRNAs coupled with coculture studies showed the influence of LDIR-modulated TNF-α, IL-1α, cMYC, and SOD2 in induced radiation protection in bystander cells. NFκB inhibition/overexpression studies coupled with coculture experiments demonstrated that TNF-α, IL-1α, cMYC, and SOD2 are selectively regulated by LDIR-induced NFκB. Conclusions: Together, these data strongly suggest that scattered LDIR-induced NFκB-dependent TNF-α, IL-1α, cMYC, and SOD2 mediate radiation protection to the subsequent challenge dose in tumor cells.
Full Text Available The purpose of the present investigation was to analyse interviews of highly regarded Finnish magicians. Social network analysis (N=120 was used to identify Finland’s most highly regarded magicians (N=16. The selected participants’ careers in professional magic and various aspects of their professional conduct were examined by relying on semi-structured interviews. The results revealed that cultivation of professional level competence in magic usually requires an extensive period of time compared with other domains of expertise. Magic is a unique performing art and it differs from other professions focusing on deceiving the audience. A distinctive feature of magical expertise is that the process takes place entirely through informal training supported by communities of magical practitioners. Three interrelated aspects of magical activity were distinguished: magic tricks, performance, and audience. Although magic tricks constitute a central aspect of magic activity, the participants did not talk about their tricks extensively; this is in accordance with the secretive nature of magic culture.The interviews revealed that a core aspect of the magicians’ activity is performance in front of an audience that repeatedly validates competence cultivated through years of practice. The interviewees reported investing a great deal of effort in planning, orchestrating, and reflecting on their performances. Close interaction with the audience plays an important role in most interviewees’ activity. Many participants put a great deal of effort in developing novel magic tricks. It is common to borrow magic effects from fellow magicians and develop novel methods of implementation. Because magic tricks or programs are not copyrighted, many interviewees considered stealing an unacceptable and unethical aspect of magical activity. The interviewees highlighted the importance of personality and charisma in the successful pursuit of magic activity.
Full Text Available Groove is the experience of wanting to move when hearing music, such as snapping fingers or tapping feet. This is a central aspect of much music, in particular of music intended for dancing. While previous research has found considerable consistency in ratings of groove across individuals, it remains unclear how groove is induced, that is, what are the physical properties of the acoustic signal that differ between more and less groove-inducing versions. Here, we examined this issue with a performance experiment, in which 4 musicians performed 6 simple and 6 complex melodies in two conditions with the intention of minimizing and maximizing groove. Analyses of rhythmical and temporal properties from the performances demonstrated some general effects. For example, more groove was associated with more notes on faster metrical levels and syncopation, and less groove was associated with deadpan timing and destruction of the regular pulse. We did not observe that deviations from the metrical grid (i.e. micro-timing were a predictor of groove. A listener experiment confirmed that the musicians’ manipulations had the intended effects on the experience of groove. A Brunswikian lens model was applied, which estimates the performer-perceiver communication across the two experiments. It showed that the communication achievement for simple melodies was 0.62, and that the matching of performers’ and listeners’ use of 9 rhythmical cues was 0.83. For complex melodies with an already high level of groove, the corresponding values were 0.39 and 0.34, showing that it was much more difficult to take out groove from musical structures designed to induce groove.

Musicians are often compared to athletes because of the physical exertion required to play music. The aim of this study was to explore the physical activity level of music students and to study its relationship with musculoskeletal complaints. A second goal was to assess associations between physical activity and pain, quality of life, and disability. This cross-sectional study among third- and fourth-year music students used an electronic survey including measures for physical activity (SQUASH-Short Questionnaire to Assess Health-enhancing physical activity), musculoskeletal complaints (DMQ-Dutch Musculoskeletal Questionnaire), disability (DASH-Disability Arm, Shoulder, Hand questionnaire) and quality of life (Short Form-12). Students were classified as compliers or non-compliers with moderate- and vigorous-intensity physical activity recommendations. Statistical analysis was done using (non)parametric tests (t-test, Pearson chi-square test, Mann-Whitney U-test) and correlational testing. Participants were 132 students, 63.6% female, with a median age of 23 yrs (range 21.3-25.0). 67% reported musculoskeletal complaints in the past 7 days. Their median physical activity level was 6,390 MET-min/wk, and 62% and 10% of the students accomplished recommendations for moderate-intensity and vigorous-intensity physical activity levels, respectively. No significant differences were found in prevalence of musculoskeletal complaints between students who met moderate- or vigorous-intensity physical activity recommendations and students who did not. Physical activity level was not associated with musculoskeletal complaints (r=0.12, p=0.26). Higher pain intensity was associated with a lower quality of life (r=-0.53 pMusic students are mainly involved in light- to moderate-intensity physical activities and rarely in vigorous-intensity activities. No correlation was found between physical activity level in the past months and musculoskeletal complaints in music students.

Reactive oxygen species (ROS) derived from NADPH oxidase (NOX) and mitochondria play a critical role in growth factor-induced switch from a quiescent to an angiogenic phenotype in endothelial cells (ECs). However, how highly diffusible ROS produced from different sources can coordinate to stimulate VEGF signaling and drive the angiogenic process remains unknown. Using the cytosol- and mitochondria-targeted redox-sensitive RoGFP biosensors with real-time imaging, here we show that VEGF stimulation in human ECs rapidly increases cytosolic RoGFP oxidation within 1 min, followed by mitochondrial RoGFP oxidation within 5 min, which continues at least for 60 min. Silencing of Nox4 or Nox2 or overexpression of mitochondria-targeted catalase significantly inhibits VEGF-induced tyrosine phosphorylation of VEGF receptor type 2 (VEGFR2-pY), EC migration and proliferation at the similar extent. Exogenous hydrogen peroxide (H 2 O 2 ) or overexpression of Nox4, which produces H 2 O 2 , increases mitochondrial ROS (mtROS), which is prevented by Nox2 siRNA, suggesting that Nox2 senses Nox4-derived H 2 O 2 to promote mtROS production. Mechanistically, H 2 O 2 increases S36 phosphorylation of p66Shc, a key mtROS regulator, which is inhibited by siNox2, but not by siNox4. Moreover, Nox2 or Nox4 knockdown or overexpression of S36 phosphorylation-defective mutant p66Shc(S36A) inhibits VEGF-induced mtROS, VEGFR2-pY, EC migration, and proliferation. In summary, Nox4-derived H 2 O 2 in part activates Nox2 to increase mtROS via pSer36-p66Shc, thereby enhancing VEGFR2 signaling and angiogenesis in ECs. This may represent a novel feed-forward mechanism of ROS-induced ROS release orchestrated by the Nox4/Nox2/pSer36-p66Shc/mtROS axis, which drives sustained activation of angiogenesis signaling program.

activities were found to participate in plFM by both components. In contrast, GABAA receptor activities are involved in the component of fractional reduction only. These findings suggest that NO orchestrates a repertoire of excitatory and inhibitory neurotransmissions, incurs a shunting effect on postsynaptic membrane properties, and thus, alters sympathetic firing in a manner of plFM. We propose that the plFM mediated by NO forms a basic scheme of differential controls for heterogeneous sympathetic regulation of visceral functions.

Olivier Messiaen (1908~1992 ) was a great French composer of the 20th century. This paper discussed his later orchestral works composed after the 1970s, which were rarely analyzed or studied in China. Main composition characteristics of Messiaen’s last six orchestral works were analyzed and summarized as follows. First-ly, in the aspect of structure thinking, his works used multi-materials, multi-color juxtaposition and symmetry. Secondly, his composition was more extensively influ-enced by synaesthesia. Thirdly, symphonic characteristics of birdsongs were fully demonstrated in his last six orchestral works. Finally, just like his other works, these six works were deeply influenced by religion or relevant themes.%文章选取了国内20世纪法国作曲家奥利维耶·梅西安(Olivier Messiaen，1908～1992)在70年代以后创作的晚期管弦乐作品为研究对象，归纳总结了梅西安晚期的六部管弦乐作品的在创作上的主要特点与整体特征。首先，在结构思维上主要体现出多材料、多色彩并置与对称性。其次，在音乐创作上受到了更宽泛的“联觉”影响。再次，晚期六部管弦乐作品充分表现出鸟歌的交响性。最后，这六部管弦乐作品深远地受到宗教题材影响。

Full Text Available This article describes a project delivered by Jessie’s Fund, a UK charity which supports children through music therapy and creative music work. The project took place between January and July 2012 and involved staff and pupils from a special school in the north of England. The article describes briefly how music is delivered in special schools across the UK and explains some of the challenges Jessie’s Fund has faced in having a lasting impact on how schools cover the music curriculum for children with complex needs. In 2012 Jessie’s Fund partnered with a special school in the north of England to design a new approach which focused intensively on the development needs of staff. Jessie’s Fund musicians visited pairs of staff over a period of six months to build their skills and confidence in leading music sessions with their pupils. The project was considerably more effective than some previous ‘musician-led’ activities and had a significant, whole-school impact. This article describes the work that took place, the responses from the staff involved and how Jessie’s Fund intends to use this learning for future projects.

People with autistic spectrum disorder (ASD) are affected by a long-life disabling condition, characterized by communication deficits, severe impairments in social functioning, and stereotyped behaviors. Although ASD individuals display several problems in interactions, it has been reported that they may show a peculiar interest in music. Previous studies have suggested a pivotal role for the dopaminergic system in the psychobiology of reward, including the pleasure of music. In the present study, we sought to investigate dopamine DRD3 and DRD4 receptor expression in peripheral blood lymphocytes of adult healthy musicians and age- and gender-matched patients with ASD against the background hypothesis that the dopaminergic system may contribute a biological cause to the reward dimensions of the musical experience in both healthy and autistic individuals. ANOVA showed significant differences in DRD4 mRNA expression between the groups (P = 0.008). Post-hoc analysis showed significant differences between the control group and both musicians (P dopamine DRD4 receptor, music and autism, possibly via mechanisms involving the reward system and the appraisal of emotions.
The orchestra conductor is a popular metaphor for managers today--up there on the podium in complete control. But that image may be misleading, says Henry Mintzberg, who recently spent a day with Bramwell Tovey, conductor of the Winnipeg Symphony Orchestra, in order to explore the metaphor. He found that Tovey does not operate like an absolute ruler but practices instead what Mintzberg calls covert leadership. Covert leadership means managing with a sense of nuances, constraints, and limitations. When a manager like Tovey guides an organization, he leads without seeming to, without his people being fully aware of all that he is doing. That's because in this world of professionals, a leader is not completely powerless--but neither does he have absolute control over others. As knowledge work grows in importance, the way an orchestra conductor really operates may serve as a good model for managers in a wide range of businesses. For example, Mintzberg found that Tovey does a lot more hands-on work than one might expect. More like a first-line supervisor than a hands-off executive, he takes direct and personal charge of what is getting done. In dealing with his musicians, his focus is on inspiring them, not empowering them. Like other professionals, the musicians don't need to be empowered--they're already secure in what they know and can do--but they do need to be infused with energy for the tasks at hand. This is the role of the covert leader: to act quietly and unobtrusively in order to exact not obedience but inspired performance.
Full Text Available The article reviews teachers' attitudes towards the teaching profession which can be expressed both in professional commitment and in professional marginalism. The dominance of professional marginalism could affect destructively the students as well as the teacher’s personality, hence the issues related to the content of personal position of a marginal and the rate of marginalism among teachers. It was suggested that marginalism could be revealed in the study of professional commitment. The study involved 81 teachers of Sverdlovsk secondary schools aged 21—60 years with work experience ranging from 1 month to 39 years. The Professional Commitment Questionnaire was used as the study technique. The results showed that negative emotional attitude towards the profession and reluctance to leave the profession were grouped as a separate factor. The dispersion factor was 12,5%. The factor loadings ranged from 0.42 to 0.84. The study proved that professional marginalism in teachers includes dissatisfaction with work, feelings of resentment against profession and an unwillingness to leave the profession.

Full Text Available Professional performance in education is now calling the attention of researcher due to its role in the professionalizing process intended to increase international education standards. In this article the term professional performance is examined from the two socio-historic traditional roles involved in training the individuals as a bio-psychic and social entity: teachers and executive. By means of scientific methods, the author gives the theoretical grounds connecting professional performance, learning and individual capacity of using them in solving problem at his labor position. The professional performance is regarded as a human value that stimulates the activity. By predicting educational alternatives, the paper portraits a model of professional performance in education, referring the necessary actions needed for achieving the goals of education. Searching and discussing such alternatives leads to reinterpret professional problems and to find out ways of improving educational standards.
The approach of an individual in the nuclear training environment to his colleagues, trainees, and his own personal growth should be determined by his desire to be a professional.

Historically, the early professionalization movements in medicine and the law appear as organizational projects which aspire to monopolize income and opportunities in markets of services or labor and to monopolize status and work privileges in occupational hierarchies. Their central task is to standardize training and link it to actual or potential markets of labor or services, a linkage that is structurally effected in the modern university. The second wave of professionalization has different protagonists than the older "market professions": placed in a different structural situation, the bureaucratic professions transform the model of profession (which they adopt as a strategy of collective ascension) into an ideology. The import of the ideology of professionalism is examined in relation to two issues: the relationships between professional occupations and bureaucratic organizations; and the position of professional occupations within the larger structure of inequality. Analysis of the first point requires consideration of the distinctions between professional occupations in the public and private sectors, the use of professional knowledge and the image of profession in bureaucratic organizations, and the specific characteristics of professions that produce their own knowledge. In the discussion of the second point, professional occupations and their ideology are examined in relation to other occupations and to the possibilities of political awareness generated by uncertain professional statuses.

The widespread use of digital media (both computing devices and the services they access) has blurred the boundaries between our personal and professional lives. Contemporary students are the last to remember a time before the widespread use of the Internet and they will be the first to practice in a largely e-health environment. This article explores concepts of digital professionalism and their place in contemporary medical education, and proposes a series of principles of digital professionalism to guide teaching, learning and practice in the healthcare professions. Despite the many risks and fears surrounding their use, digital media are not an intrinsic threat to medical professionalism. Professionals should maintain the capacity for deliberate, ethical, and accountable practice when using digital media. The authors describe a digital professionalism framework structured around concepts of proficiency, reputation, and responsibility. Digital professionalism can be integrated into medical education using strategies based on awareness, alignment, assessment, and accountability. These principles of digital professionalism provide a way for medical students and medical practitioners to embrace the positive aspects of digital media use while being mindful and deliberate in its use to avoid or minimize any negative consequences.

Musical performance is a skilled activity performed under intense pressure, thus is often a profound source of anxiety. In other contexts, anxiety and its concomitant symptoms of sympathetic nervous system arousal have been successfully ameliorated with HRV biofeedback (HRV BF), a technique involving slow breathing which augments autonomic and emotional regulatory capacity. This randomised-controlled study explored the impact of a single 30-minute session of HRV BF on anxiety in response to a highly stressful music performance. A total of 46 trained musicians participated in this study and were randomly allocated to a slow breathing with or without biofeedback or no-treatment control group. A 3 Group×2 Time mixed experimental design was employed to compare the effect of group before and after intervention on performance anxiety (STAI-S) and frequency domain measures of HRV. Slow breathing groups (n=30) showed significantly greater improvements in high frequency (HF) and LF/HF ratio measures of HRV relative to control (n=15) during 5 minute recordings of performance anticipation following the intervention (effect size: η(2) =0.122 and η(2) =0.116, respectively). The addition of biofeedback to a slow breathing protocol did not produce differential results. While intervention groups did not exhibit an overall reduction in self-reported anxiety, participants with high baseline anxiety who received the intervention (n=15) displayed greater reductions in self-reported state anxiety relative to those in the control condition (n=7) (r=0.379). These findings indicate that a single session of slow breathing, regardless of biofeedback, is sufficient for controlling physiological arousal in anticipation of psychosocial stress associated with music performance and that slow breathing is particularly helpful for musicians with high levels of anxiety. Future research is needed to further examine the effects of HRV BF as a low-cost, non-pharmacological treatment for music

Both playing a musical instrument and playing sport produce brain adaptations that might affect sensory-motor functions. While the benefits of sport practice have traditionally been attributed to aerobic fitness, it is still unknown whether playing an instrument might induce similar brain adaptations, or if a specific musical instrument like drums might be associated to specific benefits because of its high energy expenditure. Since the aerobic costs of playing drums was estimated to be comparable to those of average sport activities, we hypothesized that these two groups might show both behavioral and neurocognitive similarities. To test this hypothesis, we recruited 48 young adults and divided them into four age-matched groups: 12 drummers, 12 athletes, 12 no-drummer musicians and 12 non-athletes. Participants performed a visuo-motor discriminative response task, namely the Go/No-go, and their cortical activity was recorded by means of a 64-channel electroencephalography (EEG). Behavioral performance showed that athletes and drummers were faster than the other groups. Electrophysiological results showed that the pre-stimulus motor preparation (i.e. the Bereitschaftspotential or BP) and attentional control (i.e., the prefrontal negativity or pN), and specific post-stimulus components like the P3 and the pP2 (reflecting the stimulus categorization process) were enhanced in the athletes and drummers' groups. Overall, these results suggest that playing sport and drums led to similar benefits at behavioral and cognitive level as detectable in a cognitive task. Explanations of these findings, such as on the difference between drummers and other musicians, are provided in terms of long-term neural adaptation mechanisms and increased visuo-spatial abilities.

Many professionals prefer to work in nonprofit organizations, rather than in either for-profit or bureaucratic organizations. This preference suggests that nonprofits may be successful in reducing the tension between professional principles and institutional requirements. Professionals in for-profit organizations must submit to the control of a manager who is motivated to overrule them whenever their decisions come into conflict with the goal of profit maximization. Bureaucratic organizations stress predictability of results and adherence to rules as the overriding criteria of evaluation and control. This paper argues that nonprofits are on the whole superior from the point of view of professional ideology and practice. Thus, given a commitment to the values of professionalism, the preference for the nonprofit form becomes understandable, even without the usual assumptions about income-maximizing behavior.

Despite evidence that large professional networks afford a host of financial and professional benefits, people vary in how motivated they are to build such networks. To help explain this variance, the present article moves beyond a rational self-interest account to examine the possibility that identity shapes individuals' intentions to network. Study 1 established a positive association between viewing professional networking as identity-congruent and the tendency to prioritize strengthening and expanding one's professional network. Study 2 revealed that manipulating the salience of the self affects networking intentions, but only among those high in networking identity-congruence. Study 3 further established causality by experimentally manipulating identity-congruence to increase networking intentions. Study 4 examined whether identity or self-interest is a better predictor of networking intentions, providing support for the former. These findings indicate that identity influences the networks people develop. Implications for research on the self, identity-based motivation, and professional networking are discussed.

Full Text Available This paper aims at exploring diverse stages in the research on the educator, passing through three specific moments: in the first one, the research focuses on the teacher’s skills; in the second, on the education philosophy, and finally, the knowledge of the educator is analyzed in the third one. The professional knowledge of teaching diverges from the exercise of a specific discipline; thus, for example, to be a teacher of music is not the same thing as being a musician. From this perspective, two different research approaches on the professional knowledge of the teacher are herein presented: the first one is that of the Research and School Renewal Group (IRES from the University of Seville, while the other comes from the research group Through the Classrooms of Colombia (INVAUCOL, from the Universidad Pedagógica Nacional of Colombia. After analyzing the panorama about the teacher’s professional knowledge, the article closes by asking some questions and advancing some proposals on the formation of music educators.

Full Text Available Introduction. We discuss the concept of core competencies applied to policies for teaching and training information professionals, particularly librarians. Method. Sixty graduates of the Institute were employed as information professionals. These sixty were asked to attribute degrees of importance to specific items associated with knowledge and skills that, within the scope of this research, were considered core competencies for meeting the demands of their jobs. Participants were also asked to cite knowledge they acquired in school and knowledge they use in exercising their profession, the skills that they consider necessary but that they did not gain in school, and the difficulties they encounter in exercising their profession and for which they were not sufficiently well prepared. Analysis. Both quantitative and qualitative data analyses were performed. The data were tabulated using Access and several reports and cross-tabulations were generated. Results. The results suggest a gulf between knowledge and skills acquired in library school and those that are required by the job market. In particular, participants lacked the skills they needed to work with information and communication technologies. Conclusion. The concept of core competencies is increasingly taken into account by the productive sector of the economy. The educational system ought to keep up with this change. The empirical research described shows that there is a need to establish advanced and modern policies for the education of librarians, participants in the market for information professionals.

Turnover among healthcare professionals is a costly consequence. The existing body of knowledge on healthcare professional turnover is correlated with job satisfaction levels. A landmark study differentiated 2 areas of job satisfaction categories: satisfiers and dissatisfiers (intrinsic and extrinsic motivators). The aim of this article is to examine existing research on precursors of turnover, such as burnout behaviors experienced by healthcare professionals, job satisfaction levels, employee organizational commitment, health complications which precede turnover, some current strategies to reduce turnover, and some effects CEO turnover has on employee turnover intentions.

Further Education lecturers appear to be stranded in a professional wilderness, deemed to fall short of the virtues of school teachers and lacking the academic credentials of university lecturers. One response to this apparent lack of status was an attempt to re-professionalise the FE workforce, most notably through the work of its first professional body, the Institute for Learning (IfL). This essay charts the ups and downs of the professionalisation agenda in Further Education and its impac...

What is a profession? According to Cruess, it is an occupation whose core element is work that is based on the mastery of a complex body of knowledge and skills. It is a vocation in which knowledge of some department of science or learning, or the practice of an art founded on it, is used in the service of others. Its members profess a commitment to competence, integrity, morality, altruism, and the promotion of the public good within their domain. These commitments form the basis of a social contract between a profession and society, which in return grants the profession autonomy in practice and the privilege of self-regulation. Although medical professionals share the role of healer, there are wide variations between individuals. Professionalism is the basis of medicine's contract with society. Public trust is essential to that contract, and public trust depends on the integrity of both individual professionals and the whole profession. The introduction to this important symposium includes definitions of professions and of medical professionalism. It also includes discussions of reciprocal altruism, conflicts of interest in medical societies, the theory of cognitive dissonance, and the moral foundations of professionalism.

Emotion is a primary motivator for creative behaviors, yet the interaction between the neural systems involved in creativity and those involved in emotion has not been studied. In the current study, we addressed this gap by using fMRI to examine piano improvisation in response to emotional cues. We showed twelve professional jazz pianists photographs of an actress representing a positive, negative or ambiguous emotion. Using a non-ferromagnetic thirty-five key keyboard, the pianists improvised music that they felt represented the emotion expressed in the photographs. Here we show that activity in prefrontal and other brain networks involved in creativity is highly modulated by emotional context. Furthermore, emotional intent directly modulated functional connectivity of limbic and paralimbic areas such as the amygdala and insula. These findings suggest that emotion and creativity are tightly linked, and that the neural mechanisms underlying creativity may depend on emotional state.
