Preparation for the operatic stage means that for some students their voice will undergo significant transformation during training. For most operatic singers, voice type will determine future roles, the music they perform and potential career trajectory. Voice type becomes a facet of identity and position within the operatic world. This article presents a narrative thematic analysis of a young woman's account of her teaching and learning experiences in preparation for a career on the operatic stage. Two semi-structured interviews were conducted, and beliefs and values about her singing and voice type were elicited. This article discusses how significant changes to her voice have affected her self-concept, singer identity and potential career in opera. Also discussed is the impact of conservatorium environment, peers and mentors on her feelings of self-belief.

Maternal immunisation, a low cost and high efficacy intervention is recommended for its pathogen specific protection. Evidence suggests that maternal immunisation has another significant impact: reduction of preterm birth (PTB), the single greatest cause of childhood morbidity and mortality globally. Our overarching question is: how does maternal immunisation modify the immune system in pregnant women and/or their newborn to reduce adverse pregnancy outcomes and enhance the newborn infant's capacity to protect itself from infectious diseases during early childhood? To answer this question we are conducting a multi-site, prospective observational cohort study collecting maternal and infant biological samples at defined time points during pregnancy and post-partum from nulliparous women. We aim to enrol 400 women and determine the immune trajectory in pregnancy and the impact of maternal immunisation (including influenza, pertussis and/or COVID-19 vaccines) on this trajectory. The results are expected to identify areas that can be targeted for future intervention studies. [ABSTRACT FROM AUTHOR]

This article reports on a case study of three directors of large ensembles within a large conservatoire and the ways in which they attempted to scaffold their students into professional music careers. The core aim in this article is to respond to the question "What is the role and function of the ensemble experience on the training of the professional musician?" The study reported on here formed part of a larger project into ensemble assessment practices. However as the study progressed, it became clear that each director perceived that their responsibilities to their students extended well beyond the institutional imperatives of reporting on progress and assessment practices. The sub-questions that relate to this aspect of the study therefore included: "What is the rationale for activities within the ensemble?" "How does the ensemble director facilitate and enable this learning experience?" and "What activities does the director see as intrinsic to the overall ensemble experience?" Using a case study approach, the ensembles involved were observed and their directors were interviewed. Artifacts were also used to support the data generated. These included course outlines, detailed rehearsal expectations and other university prerequisites. The data are presented as narrative accounts of each director. While Directors centered their practices on short-term rehearsal and performance outcomes, they were also keenly aware of the need for students to develop generic musicianship skills and to ensure the development of self-management strategies for life after the conservatoire.

Participation in an ensemble is a significant aspect of tertiary music experience. Learning and assessment practices within ensembles have rarely been investigated in Australia and the perceptions of staff and students as to how they learn and are assessed within ensembles remain largely unexplored. This paper reports on part of a larger project that investigated learning and assessment practices within ensembles at an Australian Conservatorium of Music. Ensembles contribute to approximately 25% of student work in each semester, and the assessment contributes to a final grade for the semester. Using a case study methodology, four music ensembles were studied. The data generated were coded into themes including assessment practices and processes; collaborative learning practices; the development of the professional musician; and communication and transparency between participants and the institution. Findings revealed that both staff and student participants in this study perceived ensemble participation to be valuable to the development of a professional musician, but that assessment procedures did not always support this goal. Institutional demands were found to be an inhibiting factor in the assessment of ensembles, and both students and teachers had problems with current assessment procedures, resulting in confusion and lack of transparency about how ensembles are assessed. Approaches to the development of the professional musician became a dominant discussion point and a substantial finding of the research. By examining dominant and subjugated knowledge in this domain, institutional power relations were interrogated, existing practices were challenged, and assessment practices rethought.

A common herbicide, atrazine, is associated with poor health. Atrazine acts as an endocrine disruptor at supra-environmental levels. Little research, however, has been conducted regarding chronic exposure to environmental atrazine concentrations across generations. This study utilized comprehensive endpoint measures to investigate the effects of chronic exposure to a conservative atrazine concentration (0.02 ng/mL), measured in Australian waterways, on male mice fertility across two generations. Mice were exposed through the maternal line, from the pre-conception period and through the F1 and F2 generations until three or six months of age. Atrazine did not impact sperm function, testicular morphology nor germ cell parameters but did alter the expression of steroidogenic genes in the F1, down-regulating the expression of Cyp17a1 (Cytochrome P450 family 17, subfamily A member 1; p = 0.0008) and Ddx4 (DEAD-box helicase 4; p = 0.007), and up-regulating the expression of Star (Steroidogenic acute regulatory protein; p = 0.017). In the F2, atrazine induced up-regulation in the expression of Star (p = 0.016). The current study demonstrates that chronic exposure to an environmentally relevant atrazine concentration perturbs testicular steroid-associated gene expression that varies across generations. Future studies through the paternal and combined parental lineages should be undertaken to further elucidate the multigenerational effects of atrazine on male fertility. [ABSTRACT FROM AUTHOR]

One-to-one lessons based on the master-apprentice model are recognised in research and practice as an indispensable foundation for the training of professional musicians including singers. Given its primary importance to musician training, it is essential that researchers of this pedagogical model adopt methodologies and methods well-suited to illuminating the unique nature of one-to-one pedagogy. This article on methodology introduces multi-sited ethnography (MSFE) for one-to-one pedagogy research, exemplified through its use in a research project focused on one-to-one musical theatre singing voice pedagogy. MSFE is presented as 'Big Q' qualitative research approach which cohesively engages with epistemological, ontological, and methodological considerations facilitating the use of research methods which are well-suited to the private and ephemeral nature of the one-to-one lesson. MSFE is positioned as a research methodology which extends on and can address the challenges of extant research approaches in one-to-one pedagogy. MSFE is of particular use when researching participants across a broad cultural group (for example, studio teachers of a particular instrument or voice at multiple educational sites). We conclude with a discussion of the limitations of MSFE and make recommendations for further research. [ABSTRACT FROM AUTHOR]

Chronic pain is a prevalent and debilitating health problem that often persists in the absence of an identifiable biomedical cause. Uncertainty regarding the origins of a pain problem may lead to pain catastrophizing and unfruitful healthcare seeking behaviors. Individuals with chronic pain often turn to the internet to identify possible causes or sources of their pain symptoms, thus affirming their pain experience. Despite evidence that pain catastrophizing amplifies distress about pain complaints, no studies have investigated whether it is associated with escalations in health anxiety that result from searching for online health information (i.e., cyberchondria). The aim of the present study was to investigate whether pain catastrophizing predicted variance in cyberchondria above and beyond health anxiety. Undergraduate students (N = 221, 70.6% female) completed questionnaires assessing pain catastrophizing, health anxiety, and cyberchondria. Results from hierarchical regression models indicated that pain catastrophizing predicted unique variance in four dimensions of cyberchondria: compulsion, distress, excessiveness, and reassurance. Findings are consistent with research highlighting the consequences of pain catastrophizing on myriad psychological outcomes. Individuals who catastrophize about pain experiences may be vulnerable to developing severe health anxiety from searching the internet for health information. Implications for research among individuals with chronic pain are discussed. [ABSTRACT FROM AUTHOR]
