Music listening and hearing aids: perspectives from audiologists and their patients

Objective: Two studies explored hearing-aid user and audiologist experiences of hearing-aid use and fitting for music in the UK. Design and sample: One-hundred-seventy-six hearing-aid users (age range: 21–93 years; mean: 60.56 years) answered a 4-item questionnaire on music listening difficulties and discussions about music in clinic. 99 audiologists (age range: 22–71 years; mean: 39.18 years) answered a 36-item questionnaire on the frequency and type of discussions, training received, and strategies for optimizing hearing aids for music. Closed and open-ended questions were included. Results: Sixty seven percent of hearing-aid users reported some degree of difficulty listening to music with hearing aids, and 58% had never discussed music in clinic. 50% of audiologists surveyed asked 1 in 5 (or fewer) patients about music and 67% had never received music-specific training. Audiologist training on music was significantly associated with confidence in providing advice, confidence in programming hearing aids for music, and programming hearing aids for music for a greater number of patients. Conclusions: Hearing-aid users’ and audiologists’ experiences of music remain mixed. In the absence of formalised training in optimizing hearing aids for music, there is a need for systematic research relating fitting strategies to clinical outcomes and the development of guidelines for audiologist training

Mindfulness for musicians: A mixed methods study investigating the effects of 8-week mindfulness courses on music students at a leading conservatoire

Mindfulness courses are beneficial in clinical domains for anxiety and depression and are becoming more prevalent as interventions in education. However, little is known about what effects mindfulness might have on musicians. In an exploratory study, 25 music students, who completed one of four 8-week MBSR/MBCT mindfulness courses adapted for musicians at the Guildhall School of Music and Drama, completed the validated Five Facet Mindfulness Questionnaire and a bespoke Mindfulness for Musicians questionnaire pre- and post-intervention. Twenty-one music students also took part in a post-intervention one-to-one semi-structured interview. Post-intervention mindfulness scores for both questionnaires increased significantly in comparison to pre-intervention scores. In interviews, participants were reportedly more aware and focused in instrumental lessons, were less self-critical, and developed increased body awareness, which improved their learning of instrumental technique. Participants also described enhanced teacher/pupil communication. In instrumental practice sessions, participants reported more efficient, effective and creative practice, and said that mindfulness exercises helped them deal with problems experienced while practising. Participants also described enhanced listening skills and improved socio-collaboration in ensemble rehearsals. They reported that mindfulness strategies had positive effects on music performance anxiety and described changes in time perception, enhanced expressivity, and positive post-performance effects. Future researchers could adopt a more robust methodology, such as a randomised controlled trial, and incorporate further design elements, such as longitudinal follow-up. Providing more systematic evidence of the beneficial role of mindfulness for conservatoire music students as learners and performers may encourage greater provision of such opportunities in musical settings in the future

Results of an Environmental Scan to Determine the Level of Uncorrected Refractive Error in First Nations Elementary School Children in Ontario

A survey was developed and used to determine the level and quality of vision care services available to First Nations elementary school children across Ontario, and to indirectly determine the level of uncorrected refractive error in First Nations children. Overall, the total survey results showed that 1 child in 4 wore glasses. The results from the survey indicated that remote communities that had a visiting optometrist were more likely to have fewer cases of uncorrected refractive error than non-remote communities. The results suggest that in-community comprehensive eye exams delivered on a regular basis by visiting optometrists would be the most effective way of improving the vision and eye health status of First Nations children

Attending live music events with a visual impairment: experiences, accessibility and recommendations for the future

Purpose The current article focuses on the experiences of live music event attendees with visual impairment (VI). It outlines the factors which impact on the accessibility of events and considers how accessibility might be improved for these individuals. Design/methodology/approach The article reports on findings from a mixed-methods project utilising a structured interview study (N = 20) and an online survey (N = 94). Interview data were analysed using Interpretative Phenomenological Analysis, providing in-depth insight into participants’ experiences before and during events. Quantitative survey data were analysed descriptively and statistically, and Thematic Analysis of open-ended responses was carried out. Findings Attendance at live events varied amongst participants, and so too did the factors impacting on their attendance. Challenges were identified in relation to several key areas: accessing information and tickets, experiences with staff, navigation and orientation, and the use and availability of disabled facilities and specialist services. Originality/value This article is the first to offer in-depth exploration of music event accessibility for individuals with VI. It builds on existing research which has considered the experiences of deaf and disabled attendees but has not yet offered adequate representation of individuals with VI. The article offers practical recommendations for venues and organisers seeking to ensure accessible events for all and contributes to the wider discourse surrounding inclusivity at music, arts and cultural events

Collaboration in multi-tier supply chains for reducing empty running: a case study in the UK retail sector

This research aims to explore ways to improve transport efficiency in retail multi-tier supply chains by integrating raw material sourcing of suppliers into the transport network. The performance of the proposed scenario is assessed using a discrete-event simulation (DES) model that includes the additional pick-up and drop-off points of an extended transport network. The results suggest an improvement in the transport network efficiency, evidenced in the reduction of empty running levels and costs. This study supports the idea that the integration of raw material sourcing of suppliers into a retailer's transport network can bring significant benefits

Pharmacological profiling of the hemodynamic effects of cannabinoid ligands: a combined in vitro and in vivo approach

The receptors mediating the hemodynamic responses to cannabinoids are not clearly defined due to the multifarious pharmacology of many commonly used cannabinoid ligands. While both CB1 and TRPV1 receptors are implicated, G protein-coupled receptor 55 (GPR55) may also mediate some of the hemodynamic effects of several atypical cannabinoid ligands. The present studies attempted to unravel the pharmacology underlying the in vivo hemodynamic responses to ACEA (CB1 agonist), O-1602 (GPR55 agonist), AM251 (CB1 antagonist), and cannabidiol (CBD; GPR55 antagonist). Agonist and antagonist profiles of each ligand were determined by ligand-induced GTPγS binding in membrane preparations expressing rat and mouse CB1 and GPR55 receptors. Blood pressure responses to ACEA and O-1602 were recorded in anesthetized and conscious mice (wild type, CB1−/− and GPR55−/−) and rats in the absence and presence of AM251 and CBD. ACEA demonstrated GTPγS activation at both receptors, while O-1602 only activated GPR55. AM251 exhibited antagonist activity at CB1 and agonist activity at GPR55, while CBD demonstrated selective antagonist activity at GPR55. The depressor response to ACEA was blocked by AM251 and attenuated by CBD, while O-1602 did not induce a depressor response. AM251 caused a depressor response that was absent in GPR55−/− mice but enhanced by CBD, while CBD caused a small vasodepressor response that persisted in GPR55−/− mice. Our findings show that assessment of the pharmacological profile of receptor activation by cannabinoid ligands in in vitro studies alongside in vivo functional studies is essential to understand the role of cannabinoids in hemodynamic control

Modularization as a system life cycle management strategy:Drivers, barriers, mechanisms and impacts

This literature-grounded research contributes to a deeper understanding of modularization as a system life cycle management strategy, by providing a comprehensive view of its key barriers, drivers, possible mechanisms of implementation and impact. This comprehensive view, arranged into a decision-making–driven ontology, enables a decision maker to systematically identify modularization implementation opportunities in different industrial and service domains. The proposed ontology transforms modularization into a fully operationalizable strategy and contributes to a paradigm shift in the understanding of modularization, from a pure design option (i.e. modularity) to a fully strategic choice that, by nature, impacts on many of the system’s life cycle phases and involves a number of stakeholders

Résultats d’une analyse du milieu visant à déterminer le niveau d’erreur de réfraction non corrigée chez les enfants des écoles primaires des Premières nations de l’Ontario

Un sondage a été élaboré et utilisé pour déterminer le niveau et la qualité des services de soins de la vue offerts aux enfants des écoles primaires des Premières nations de l’Ontario et déterminer indirectement le niveau d’erreurs de réfraction non corrigées chez les enfants des Premières nations. Dans l’ensemble, les résultats du sondage ont révélé que 1 enfant sur 4 portait des lunettes. Les résultats du sondage indiquent que les collectivités éloignées qui reçoivent la visite d’un optométriste sont plus susceptibles d’avoir moins de cas d’erreurs de réfraction non corrigées que les collectivités non éloignées. Les résultats portent à croire que les examens oculaires complets effectués par des optométristes en visite dans la collectivité seraient le moyen le plus efficace d’améliorer la vision et l’état de sante oculaire des enfants des Premières nations

Interventions for promoting habitual exercise in people living with and beyond cancer

Background: This is an updated version of the original Cochrane Review published in the Cochrane Liibrary 2013, Issue 9. Despite good evidence for the health benefits of regular exercise for people living with or beyond cancer, understanding how to promote sustainable exercise behaviour change in sedentary cancer survivors, particularly over the long term, is not as well understood. A large majority of people living with or recovering from cancer do not meet current exercise recommendations. Hence, reviewing the evidence on how to promote and sustain exercise behaviour is important for understanding the most effective strategies to ensure benefit in the patient population and identify research gaps. Objectives: To assess the effects of interventions designed to promote exercise behaviour in sedentary people living with and beyond cancer and to address the following secondary questions: Which interventions are most effective in improving aerobic fitness and skeletal muscle strength and endurance? Which interventions are most effective in improving exercise behaviour amongst patients with different cancers? Which interventions are most likely to promote long-term (12 months or longer) exercise behaviour? What frequency of contact with exercise professionals and/or healthcare professionals is associated with increased exercise behaviour? What theoretical basis is most often associated with better behavioural outcomes? What behaviour change techniques (BCTs) are most often associated with increased exercise behaviour? What adverse effects are attributed to different exercise interventions? Search methods: We used standard methodological procedures expected by Cochrane. We updated our 2013 Cochrane systematic review by updating the searches of the following electronic databases: Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, Embase, AMED, CINAHL, PsycLIT/PsycINFO, SportDiscus and PEDro up to May 2018. We also searched the grey literature, trial registries, wrote to leading experts in the field and searched reference lists of included studies and other related recent systematic reviews. Selection criteria: We included only randomised controlled trials (RCTs) that compared an exercise intervention with usual care or 'waiting list' control in sedentary people over the age of 18 with a homogenous primary cancer diagnosis. Data collection and analysis: In the update, review authors independently screened all titles and abstracts to identify studies that might meet the inclusion criteria, or that could not be safely excluded without assessment of the full text (e.g. when no abstract is available). We extracted data from all eligible papers with at least two members of the author team working independently (RT, LS and RG). We coded BCTs according to the CALO-RE taxonomy. Risk of bias was assessed using the Cochrane's tool for assessing risk of bias. When possible, and if appropriate, we performed a fixed-effect meta-analysis of study outcomes. If statistical heterogeneity was noted, a meta-analysis was performed using a random-effects model. For continuous outcomes (e.g. cardiorespiratory fitness), we extracted the final value, the standard deviation (SD) of the outcome of interest and the number of participants assessed at follow-up in each treatment arm, to estimate the standardised mean difference (SMD) between treatment arms. SMD was used, as investigators used heterogeneous methods to assess individual outcomes. If a meta-analysis was not possible or was not appropriate, we narratively synthesised studies. The quality of the evidence was assessed using the GRADE approach with the GRADE profiler. Main results: We included 23 studies in this review, involving a total of 1372 participants (an addition of 10 studies, 724 participants from the original review); 227 full texts were screened in the update and 377 full texts were screened in the original review leaving 35 publications from a total of 23 unique studies included in the review. We planned to include all cancers, but only studies involving breast, prostate, colorectal and lung cancer met the inclusion criteria. Thirteen studies incorporated a target level of exercise that could meet current recommendations for moderate-intensity aerobic exercise (i.e.150 minutes per week); or resistance exercise (i.e. strength training exercises at least two days per week). Adherence to exercise interventions, which is crucial for understanding treatment dose, is still reported inconsistently. Eight studies reported intervention adherence of 75% or greater to an exercise prescription that met current guidelines. These studies all included a component of supervision: in our analysis of BCTs we designated these studies as 'Tier 1 trials'. Six studies reported intervention adherence of 75% or greater to an aerobic exercise goal that was less than the current guideline recommendations: in our analysis of BCTs we designated these studies as 'Tier 2 trials.' A hierarchy of BCTs was developed for Tier 1 and Tier 2 trials, with programme goal setting, setting of graded tasks and instruction of how to perform behaviour being amongst the most frequent BCTs. Despite the uncertainty surrounding adherence in some of the included studies, interventions resulted in improvements in aerobic exercise tolerance at eight to 12 weeks (SMD 0.54, 95% CI 0.37 to 0.70; 604 participants, 10 studies; low-quality evidence) versus usual care. At six months, aerobic exercise tolerance was also improved (SMD 0.56, 95% CI 0.39 to 0.72; 591 participants; 7 studies; low-quality evidence). Authors' conclusions: Since the last version of this review, none of the new relevant studies have provided additional information to change the conclusions. We have found some improved understanding of how to encourage previously inactive cancer survivors to achieve international physical activity guidelines. Goal setting, setting of graded tasks and instruction of how to perform behaviour, feature in interventions that meet recommendations targets and report adherence of 75% or more. However, long-term follow-up data are still limited, and the majority of studies are in white women with breast cancer. There are still a considerable number of published studies with numerous and varied issues related to high risk of bias and poor reporting standards. Additionally, the meta-analyses were often graded as consisting of low- to very low-certainty evidence. A very small number of serious adverse effects were reported amongst the studies, providing reassurance exercise is safe for this population. © 2018 The Cochrane Collaboration

myTunes: Digital music library users and their self-images

This investigation explored the relationships between individuals’ self-images and their interactions with their digital music collections via the commercially predominant program iTunes. Sixty-nine university students completed an internet-based Musical Self-Images Questionnaire (MSIQ) along with a series of questions concerning their iTunes collections. The majority of participants were highly engaged with music, regardless of their varied musical backgrounds. Factor analysis of the MSIQ data revealed two distinct self-image groups, which we label as ‘musical practitioner’ (linking ‘overall musician’, ‘performer’, ‘composer’, ‘teacher’, and ‘listener’) and ‘music consumer’ (linking ‘listener’, ‘fan’, and ‘technology user’). Participants used an average of seven attributes to categorize their music, and most consistently used one in particular to sort their collections. Those who rated themselves as higher level performers and fans used the playlist function (which involves compiling sequences of selected tracks) more often than those with lower self-ratings on those scales
