In Australia, the Teaching Performance Assessment (TPA) is a relatively new, mandatory hurdle which must be completed just prior to the graduation stage of initial teacher education (ITE) programmes. This high-stakes task is one of a growing number of requirements to come out of the standards and accountability regime as outlined in the Australian Institute for Teaching and School Leadership (AITSL) document for accreditation for ITE programmes. We delve into the public commentary about the broader commission of preservice and graduate teacher quality in general and the TPA in particular. We draw on Bernstein's pedagogic identities and deductively apply this theory to explore this phenomenon. We use a data set of publicly available legacy media and social media tweets made over a ten-month period from August 2019 to May 2020 to reveal the focus, inherent bias and pedagogic identities promoted by these public discourses. The paper concludes with discussion about the implications of these drivers on the public perception of quality in ITE and on the status of teaching more broadly., Competing Interests: Competing interestThere is no conflict of interest for any of the authors associated with this submission to The Australian Educational Researcher., (© Crown 2023.)

Worldwide HIV-1 vaccine efforts are guided by the principle that HIV-specific T cell responses may provide protection from infection or delay overt disease. However, no clear correlates of T cell-mediated immune protection have been identified. Here, we examine in a HLA-B27(+) HIV seronegative vaccinee persistent HIV-specific vaccine-induced anti-Gag CD4(+) and CD8(+) T cell responses. Although these responses exhibited those characteristics (multifunctionality, appropriate memory phenotype, and targeting of epitopes associated with long-term nonprogression) predicted to correlate with protection from infection, the subject became HIV infected. After HIV infection, the vaccine-induced CD8(+) T cells expanded, but both CD4(+) and CD8(+) T cell responses acquired the functional and phenotypic patterns characteristic of chronic HIV infection. The virus quickly escaped the vaccine-induced T cell response, and the subject progressed more rapidly than expected for someone expressing the HLA-B27 allele. These data suggest that control of HIV by vaccine-elicited HIV-specific T cell responses may be difficult, even when the T cell response has those characteristics predicted to provide optimal protection.

Objective: To investigate the characteristics and outcomes of patients who walked out from a tertiary children's hospital emergency department (ED) without seeing a medical officer., Methods: A prospective study of patients who walked-out from the ED of a children's hospital, without seeing a medical officer. Information collected at triage included demographics, presenting problems, time of arrival, time of departure and reason for leaving. Charts were reviewed and those at high risk of serious illness or adverse outcome were contacted by telephone within 24 h. Further information collected during follow up included outcome, such as adverse events and admission to hospital. Data were analysed by comparing the walk-out and non-walk-out groups with regard to demographic variables, presenting problems and outcomes., Results: Over a 29 week period, 1037 (5.5%) patients walked out from the ED of the hospital without seeing a medical officer. Comparisons between the walk-out and non-walk-out patients indicated no differences in terms of demographics. However, significant differences were found between the triage categories, presenting problems and arrival time. Of these, 829 (79.9%) were followed up by telephone. This revealed the predominant presenting problem was non-urgent and infectious in nature and no adverse events occurred. The admission rate for walk-out patients (1.5%) was significantly lower in comparison with the non-walk-out group (6.9%; odds ratio 0.2; 95% confidence interval 0.1-0.3). Walk-out patients who were eventually hospitalized had a shorter mean length of stay than non-walk-out patients (20.4 vs 34.8 h, respectively; t = 17.78, P < 0.0001)., Conclusions: Medical resources are limited and, therefore, some extended waiting in the ED is necessary. Paediatric patients who walk-out of the ED without seeing a medical officer have simple illnesses that resolve without medical intervention or adverse events.
