Metacognition in Teaching: Using A “Rapid Responses to Learning” Process to Reflect on and Improve Pedagogy

In this paper, we critically evaluate the use of a weekly “rapid responses (RR) to learning” process in the context of teaching a graduate course on research methods over a three-year period. The RR process involves use of a short set of open-ended questions about key moments in learning that students complete, in writing, during the last five minutes of each class. The questions ask students to identify salient take-away messages, note when they felt the most and least engaged, name actions taken by anyone that were affirming or confusing, and consider specific “aha” moments. Our specific aim was to assess the following questions: What was the pedagogic value of the RR process? How did it inform our teaching and to what extent were there direct benefits of the process for students as well as for us as teachers? We found that the systematic feedback we obtained in this way supports weekly monitoring of student learning, facilitates response to trouble spots, and assists in assessment of student engagement and classroom climate. It also provides insight into the efficacy of pedagogic strategies, invites students to engage in metacognitive learning about their own learning, and models a process of instructors receiving feedback and being flexible to change. For instructors, the process enhances motivation and professional development and can be used to document instructor leadership and development. Finally, it facilitates deeper appreciation of the need to better integrate student self-assessment and the development of metacognitive skills as core components of the course

Cleaning up Eta Carinae: Detection of Ammonia in the Homunculus

We report the first detection of ammonia in the Homunculus nebula around eta Carinae, which is also the first detection of emission from a polyatomic molecule in this or any other luminous blue variable (LBV) nebula. Observations of the NH3 (J,K)=(3,3) inversion transition made with the Australia Telescope Compact Array reveal emission at locations where infrared H2 emission had been detected previously, near the strongest dust emission in the core of the Homunculus. We also detect ammonia emission from the so-called ``strontium filament'' in the equatorial disk. The presence of NH3 around eta Car hints that molecular shells around some Wolf-Rayet stars could have originated in prior LBV eruptions, rather than in cool red supergiant winds or the ambient interstellar medium. Combined with the lack of any CO detection, NH3 seems to suggest that the Homunculus is nitrogen rich like the ionized ejecta around eta Car. It also indicates that the Homunculus is a unique laboratory in which to study unusual molecule and dust chemistry, as well as their rapid formation in a nitrogen-rich environment around a hot star. We encourage future observations of other transitions like NH3 (1,1) and (2,2), related molecules like N2H+, and renewed attempts to detect CO.Comment: 4 pages, accepted to ApJ letter

‘It’s Us, Or Maybe No One’: Yarning With Aboriginal Social and Emotional Wellbeing Workers From the Kimberley Region of Western Australia

Objective Social and Emotional Wellbeing (SEWB) describes the holistic model of health and wellbeing advocated for by Aboriginal and Torres Strait Islander peoples. This research explored the experiences of Aboriginal peoples employed in SEWB service delivery to identify enablers, challenges, and requirements of growing a sustainable, and empowered SEWB workforce. Methods We used a yarning methodology with seven Aboriginal SEWB workers located at Aboriginal Community Controlled Health Organisations across the Kimberley region of Western Australia. Results Three key SEWB service delivery themes were identified: 1) Role of cultural identity; 2) Barriers and enablers of SEWB service provision; 3) Building the future of the SEWB workforce. Lessons Learned SEWB services, as delivered by Aboriginal peoples within Aboriginal Community Controlled Health Organisations, have great potential to comprehensively meet the health and wellbeing needs of Aboriginal peoples and communities. To optimally undertake their role, Aboriginal SEWB staff need to: have a clear understanding of their role; good relationships within their workplace; relevant sector knowledge; a strong sense of cultural safety within the workplace; and access to meaningful professional development. Understanding the barriers and enablers experienced by SEWB staff provides a platform to meaningfully develop the future Aboriginal SEWB workforce, and delivery of SEWB services

A Search for Dense Molecular Gas in High Redshift Infrared-Luminous Galaxies

We present a search for HCN emission from four high redshift far infrared (IR) luminous galaxies. Current data and models suggest that these high $z$ IR luminous galaxies represent a major starburst phase in the formation of spheroidal galaxies, although many of the sources also host luminous active galactic nuclei (AGN), such that a contribution to the dust heating by the AGN cannot be precluded. HCN emission is a star formation indicator, tracing dense molecular hydrogen gas within star-forming molecular clouds (n(H$_2$) $\sim 10^5$ cm$^{-3}$). HCN luminosity is linearly correlated with IR luminosity for low redshift galaxies, unlike CO emission which can also trace gas at much lower density. We report a marginal detection of HCN (1-0) emission from the $z=2.5832$ QSO J1409+5628, with a velocity integrated line luminosity of $L_{\rm HCN}'=6.7\pm2.2 \times10^{9}$ K km s$^{-1}$ pc$^2$, while we obtain 3$\sigma$ upper limits to the HCN luminosity of the $z=3.200$ QSO J0751+2716 of $L_{\rm HCN}'=1.0\times10^{9}$ K km s$^{-1}$ pc$^2$, $L_{\rm HCN}'=1.6\times10^{9}$ K km s$^{-1}$ pc$^2$ for the $z= 2.565$ starburst galaxy J1401+0252, and $L_{\rm HCN}'=1.0\times10^{10}$ K km s$^{-1}$ pc$^2$ for the $z = 6.42$ QSO J1148+5251. We compare the HCN data on these sources, plus three other high-$z$ IR luminous galaxies, to observations of lower redshift star-forming galaxies. The values of the HCN/far-IR luminosity ratios (or limits) for all the high $z$ sources are within the scatter of the relationship between HCN and far-IR emission for low $z$ star-forming galaxies (truncated).Comment: aastex format, 4 figures. to appear in the Astrophysical Journal; Revised lens magnification estimate for 1401+025

"It's not as easy as saying, 'just get them to eat more veggies'": Exploring healthy eating in residential care in Australia

Young people living in residential out-of-home care (henceforth OoHC) are at increased risk of becoming overweight or obese. Currently, recognition of the everyday mechanisms that might be contributing to excess weight for children and young people in this setting is limited. The aim of this study was to better understand the barriers and complexities involved in the provision of a ‘healthy’ food environment in residential OoHC. Heightening awareness of these factors and how they might compromise a young person's physical health, will inform the development, refinement and evaluation of more sensitive and tailored weight-related interventions for this population. The paper presents a nuanced picture of the complexity of everyday food routines in residential care, and illustrates the ways in which food is ‘done’ in care; how food can be both symbolic of care but also used to exercise control; the way in which food can be used to create a ‘family-like’ environment; and the impact of traumatic experiences in childhood on subsequent behaviours and overall functioning in relation to food. It is argued that a health agenda designed for a mainstream population ignores the very complex relationship that children in residential OoHC may have with food. It is recommended that future intervention approaches account for personal food biographies, trauma and children's social backgrounds and how these are implicated in everyday practices and interactions around food

The impact of syphilis screening among female sex workers in China: a modelling study.

BACKGROUND: In China, female sex workers (FSWs) are at high risk of syphilis infection, but are hard to reach for interventions. Point-of-care testing introduces opportunities for expanding syphilis control measures. Modelling is used to estimate the impact of using rapid tests to screen FSWs for syphilis. In other settings, modelling has predicted large rebounds in infectious syphilis following screening, which may undermine any impact achieved. METHODS: A deterministic syphilis transmission model among FSWs and clients was fitted to data from Yunnan Province (FSW syphilis prevalence = 7.5%), and used to estimate the impact of rapid syphilis testing and treatment for FSWs. Impact projections were compared for different model structures that included risk heterogeneity amongst FSWs, incoming syphilis infections amongst new FSWs and clients and re-infection from FSWs' regular non-commercial partners. The rebound in syphilis prevalence after screening ceased was explored. RESULTS: All model structures suggest yearly syphilis screening could substantially reduce (by 72-88%) syphilis prevalence amongst FSWs in this setting over five years. However, incoming syphilis infections amongst new FSWs and clients or re-infections from regular non-commercial partners of FSWs can considerably reduce (>30%) the proportion of infections averted. Including heterogeneity in risk amongst FSWs had little effect upon the proportion of infections averted. In this setting, the rebound in syphilis prevalence after screening ceased is predicted to be slight, but it could be large in high prevalence settings. CONCLUSIONS: Rapid test screening could dramatically reduce syphilis prevalence amongst hard-to-reach groups, but strategies to reduce re-infection from regular non-commercial partners are needed to maximise impact
