Abstract: To investigate the experiences of audiologists and audiometrists working in regional and remote areas of Australia. A qualitative design, using telephone and videoconference semi‐structured interviews and thematic analysis. Regional and remote locations across Australia 5 audiologists and 2 audiometrists, 6 female and one male. None. Insights into the experiences of audiologists and audiometrists working in rural Australia. Core themes that emerged from analysis were (a) professional isolation and increased scope of practice, (b) the importance of social and professional networks, (c) variable access to professional support, (d) challenges in the recruitment and retention of clinicians, and (e) tensions between service provision and profitability. This study provides valuable insights into both the rewarding and challenging aspects of working as an audiologist or audiometrist in regional and remote areas. This study emphasised the need to address these challenges in order to attract more audiological professionals to work and stay in regional and remote areas of Australia.

Abstract: Financial incentive schemes have been commonly used by the hearing aid industry as a way of encouraging device sales. These schemes can lead to a conflict of interest as the hearing device dispenser is torn between personal reward over the best interests of their client. This conflict of interest has the potential for the dispenser to develop “moral distress”, a negative state of mind when an in idual’s ethical values contrast with those of the employing organization. The purpose of this study was to investigate if there was a relationship between financial incentives and moral distress in Australian audiologists and audiometrists. An online survey was distributed to all members of Audiology Australia and the Australian College of Audiology via email. Participants rated their perceived moral distress from 0 to 10 on the Moral Distress Thermometer and answered four questions about financial incentives in their respective workplace. A total of 65 participants, 42 females and 23 males, completed the online survey. A quarter of participants rated their moral distress corresponding to levels of uncomfortable or above. A statistically significant association was found between financial incentives, sales target setting, and higher perceived moral distress in participants. For our s le, the implementation of financial incentives created ethical challenges for practicing audiologists and audiometrists. Modifications to employee rewards programs as well as a regulation of device sales are recommended.

Abstract: The purpose of this study was to assess if a relationship existed between (i) audiologists’ perceptions of moral distress, (ii) occupational wellbeing, and (iii) patient-practitioner orientation. The Moral Distress Thermometer, Health and Safety Executive (HSE) Management Standards Indicator Tool and Patient-Practitioner Orientation Scale (PPOS) was sent out to all audiologists registered with the professional body Audiology Australia. Study s le: A total of 43 audiologists completed the questionnaires. Using a multiple linear regression model there was no evidence of a relationship between patient-practitioner orientation and either moral distress or occupational wellbeing. However, an association between higher moral distress and lower occupational wellbeing was demonstrated. The occupational wellbeing subscales of ‘managerial support’, ‘peer support’, ‘relationships’, ‘role’, and ‘change’ were strongly associated with poorer scores on moral distress. For our s le of audiologists, ethical conflict appeared to be linked to reduced job satisfaction. There is a need to consider ways of providing supportive organisational structures in which ethical conflicts can be openly discussed and negotiated in order to improve occupational wellbeing in the profession.

Abstract: To investigate how the profession of audiology was represented in the media in Australia and how the increased privatisation of the profession may have shaped this representation. A systematic search of English language media records was conducted from 1 January 2000 to 17 July 2020 using ANZ News Stream, TV News, Google News and INFORMIT. Twenty-four of 1056 originally identified articles were retained. The findings were extracted and synthesised. Context and content analyses were preformed, revealing a predominantly negative portrayal of Audiology as a profession in 21 (87.5%) of 24 articles. Predominant themes included: sales driven by incentives predatory strategies and malpractice non-regulation and privatisation of the hearing care industry and conflict of interest. The media was found to highlight consumer mistrust in the profession in recent years. Increased regulation of the profession of audiology is recommended to protect the population against exploitative practices and to renew faith in the profession by the public.

Abstract: The pressures of fiscal constraints, increased competition, and rapidly developing information technology have resulted in the modern university adopting business models of operation. As a consequence, teaching and learning have become products and students have become consumers. The net effect of these changes has been the expansion of specialist administrative and management work in universities: work that is undertaken by both professional staff and manager-academics. Arguably, it is these managerial practices that now drive the research and knowledge functions of the university, rather than the other way around. Typically, professional staff members, also known as “general,” “non-academic,” or “administrative” staff, now comprise the majority of the modern university workforce across Australia, Europe, the United Kingdom, and the United States. The changing roles and importance of these professional staff members is explored by describing their number, function, roles, and gender breakdown across higher education providers. In this chapter, the authors examine the growing influence of professional staff in the university's binary organizational structure of the “non-academic” versus the academic. The tensions this binary system creates in the perceptions of the relative status of one type of work and workers in higher education over another are interrogated with particular regard to staff ersity. The blurring of the binary is highlighted as academics move into managerial roles and the work of professional staff cuts across academic and administrative domains.

Abstract: For simultaneous acoustic and electric stimulation to be perceived as complementary, it may be beneficial for hearing aids and cochlear implants (CI) to be adjusted to provide compatible pitch sensations. To this end, estimates of the pitch perceived for a set of acoustic and electric stimuli were obtained from 14 CI users who had usable low-frequency hearing, either in the non-implanted ear or in both ears. The subjects assigned numerical pitch estimates to each of 5 acoustic pure tones and 5 single-electrode electric pulse trains. On average, the acoustic frequency that corresponded in pitch to stimulation on the most apical electrode was approximately 480 Hz. This was about 1 octave lower than the frequency expected from Greenwood’s frequency-place function applied to estimates of the electrode insertion angle based on X-ray images. Furthermore, evidence was found suggesting that pitch decreased with increasing duration of CI use. Pitch estimates from 5 subjects who completed the experiment before experiencing any other sounds through their CI were generally close to the values expected from a recently published frequency map for the cochlear spiral ganglion. Taken together, these findings suggest that some perceptual adaptation may occur that would compensate in part for the apparent mismatch between the intracochlear position of the electrodes and the acoustic frequencies assigned to them in the sound processor.

Abstract: Premature ovarian insufficiency (POI) is a common cause of infertility in women, characterised by amenorrhea and elevated FSH under the age of 40 years. In some cases, POI is syndromic in association with other features such as sensorineural hearing loss in Perrault syndrome. POI is a heterogeneous disease with over 80 causative genes known so far however, these explain only a minority of cases. Using whole-exome sequencing (WES), we identified a MRPL50 homozygous missense variant (c.335T A p.Val112Asp) shared by twin sisters presenting with POI, bilateral high-frequency sensorineural hearing loss, kidney and heart dysfunction. MRPL50 encodes a component of the large subunit of the mitochondrial ribosome. Using quantitative proteomics and western blot analysis on patient fibroblasts, we demonstrated a loss of MRPL50 protein and an associated destabilisation of the large subunit of the mitochondrial ribosome whilst the small subunit was preserved. The mitochondrial ribosome is responsible for the translation of subunits of the mitochondrial oxidative phosphorylation machinery, and we found patient fibroblasts have a mild but significant decrease in the abundance of mitochondrial complex I. These data support a biochemical phenotype associated with MRPL50 variants. We validated the association of MRPL50 with the clinical phenotype by knockdown/knockout of mRpL50 in Drosophila , which resulted abnormal ovarian development. In conclusion, we have shown that a MRPL50 missense variant destabilises the mitochondrial ribosome, leading to oxidative phosphorylation deficiency and syndromic POI, highlighting the importance of mitochondrial support in ovarian development and function.

Abstract: In this paper, the association between socioeconomic status and speech, language and communication outcomes for primary-school-going children with hearing loss using population survey data was analysed. The dataset used for analysis consisted of 289973 children in total, of which 3174 children had hearing loss. For all children, higher socioeconomic status was positively correlated with better speech, language and communication outcomes. A hearing loss was indicated for 1% of non-Indigenous children and 4.3% of Indigenous children. Non-Indigenous children with hearing loss were found to be fairly evenly distributed by socioeconomic status, whereas Indigenous children with hearing loss were found to be statistically significantly more likely to be living in the most disadvantaged socioeconomic areas. Socioeconomic status was found to affect developmental outcomes for all children, regardless of Indigenous and hearing loss status.

Abstract: Students from disadvantaged backgrounds have been reported to use university career services in smaller numbers than their peers. In order to address this, services have been advised to “establish ways of identifying, within their first term of study, those students who are particularly likely to need help and guidance from the Careers Service” (Harris, 2001, p. 8). By analysing two career programs—traditional stand-alone career workshops and an alternative service, which incorporates employability skills as part of a service learning program—the inclusivity of career programs and the kinds of students programs attract was explored. It was found that the program that had greater flexibility in terms of location, choice, and timing attracted a statistically significantly larger number of disadvantaged students. It is recommended that services consider contextually and critically analysing programs, systems, and methods of working to ensure that these are not disadvantaging one or more student groups.

Abstract: Premature ovarian insufficiency (POI) affects 1 in 100 women and is a leading cause of female infertility. There are over 80 genes in which variants can cause POI, with these explaining only a minority of cases. Whole exome sequencing (WES) can be a useful tool for POI patient management, allowing clinical care to be personalized to underlying cause. We performed WES to investigate two French sisters, whose only clinical complaint was POI. Surprisingly, they shared one known and one novel likely pathogenic variant in the Perrault syndrome gene, LARS2. Using amino-acylation studies, we established that the novel missense variant significantly impairs LARS2 function. Perrault syndrome is characterized by sensorineural hearing loss in addition to POI. This molecular diagnosis alerted the sisters to the significance of their difficulty in following conversation. Subsequent audiology assessment revealed a mild bilateral hearing loss. We describe the first cases presenting with perceived isolated POI and causative variants in a Perrault syndrome gene. Our study expands the phenotypic spectrum associated with LARS2 variants and highlights the clinical benefit of having a genetic diagnosis, with prediction of potential co-morbidity and prompt and appropriate medical care, in this case by an audiologist for early detection of hearing loss.

Abstract: Novel layered 2D frameworks (C 3 N and C 2 N‐450) with well‐defined crystal structures are explored for use as anode materials in lithium‐ion batteries (LIBs) for the first time. As anode materials for LIBs, C 3 N and C 2 N‐450 exhibit unusual electrochemical characteristics. For ex le, C 2 N‐450 (and C 3 N) display high reversible capacities of 933.2 (383.3) and 40.1 (179.5) mAh g −1 at 0.1 and 10 C, respectively. Furthermore, C 3 N shows a low hypothetical voltage (≈0.15 V), efficient operating voltage window with ≈85% of full discharge capacity secured at .45 V, and excellent cycling stability for more than 500 cycles. The excellent electrochemical performance (especially of C 3 N) can be attributed to their inherent 2D polyaniline frameworks, which provide large net positive charge densities, excellent structural stability, and enhanced electronic/ionic conductivity. Stable solid state interface films also form on the surfaces of the 2D materials during the charge/discharge process. These 2D materials with promising electrochemical performance should provide insights to guide the design and development of their analogues for future energy applications.
