This author accepted manuscript is made available following 24 month embargo from date of publication (July 2017) in accordance with the publisher’s archiving policyThe Gravity Recovery and Climate Experiment (GRACE) has been in operation since 2002. Water storage estimates are calculated from gravity anomalies detected by the operating satellites and although not the true resolution, can be presented as 100 km × 100 km data cells if appropriate scaling functions are applied. Estimating total water storage has shown to be highly useful in detecting hydrological variations and trends. However, a limitation is that GRACE does not provide information as to where the water is stored in the vertical profile. We aim to partition the total water storage from GRACE into water storage components. We use a wavelet filter to decompose the GRACE data and partition it into various water storage components including soil water and groundwater. Storage components from the Australian Water Resources Assessment (AWRA) model are used as a reference for the decompositions of total storage data across Australia. Results show a clear improvement in using decomposed GRACE data instead of raw GRACE data when compared against total water storage outputs from the AWRA model. The method has potential to improve GRACE applications including a means to test various large scale hydrological models as well as helping to analyse floods, droughts and other hydrological conditions
Does Achilles Forgive in the Iliad? The Archaic Origins of the Virtue of Forgivingness
Get PDFAll rights reserved © 2017, Modern Greek Studies Association of Australia and New Zealand. Reproduced with permission of the publisher.In Before Forgiveness, David Konstan argues that the modern concept of interpersonal forgiveness was absent from Western thought until the early modern period. However, by “the modern” concept of the term, Konstan means one specific modern conception of forgiveness: that articulated by Griswold in Forgiveness, a conception unique amongst modern scholarship in its narrow, revisionary and prescriptive nature. In this paper I consider Konstan’s argument with respect to archaic Greece. I argue that, even when we limit ourselves to Griswold’s conception of interpersonal forgiveness, and to the two Iliadic examples considered by Konstan, there is more room for interpersonal forgiveness in the Iliad than Konstan would have us believe. I will show that examination of Achilles’ renunciation of his resentment at Agamemnon in Iliad 18 and Priam in Iliad 24 reveals the earliest depiction in Western literature of the virtue of forgivingness

Multi-level, longer-term obesity prevention interventions that focus on inequalities are scarce. Fun ‘n healthy in Moreland! aimed to improve child adiposity, school policies and environments, parent engagement, health behaviours and child wellbeing.
Methods
All children from primary schools in an inner urban, culturally diverse and economically disadvantaged area in Victoria, Australia were eligible for participation. The intervention, fun ‘n healthy in Moreland!, used a Health Promoting Schools Framework and provided schools with evidence, school research data and part time support from a Community Development Worker to develop health promoting strategies. Comparison schools continued as normal. Participants were not blinded to intervention status. The primary outcome was change in adiposity. Repeated cross-sectional design with nested longitudinal subsample.
Results
Students from twenty-four primary schools (clusters) were randomised (aged 5–12 years at baseline). 1426 students from 12 intervention schools and 1539 students from 10 comparison schools consented to follow up measurements. Despite increased prevalence of healthy weight across all schools, after 3.5 years of intervention there was no statistically significant difference between trial arms in BMI z score post-intervention (Mean (sd): Intervention 0.68(1.16); Comparison: 0.72(1.12); Adjusted mean difference (AMD): -0.05, CI: -0.19 to 0.08, p = 0.44). Children from intervention schools consumed more daily fruit serves (AMD: 0.19, CI:0.00 to 0.37, p = 0.10), were more likely to have water (AOR: 1.71, CI:1.05 to 2.78, p = 0.03) and vegetables (AOR: 1.23, CI: 0.99 to 1.55, p = 0.07), and less likely to have fruit juice/cordial (AOR: 0.58, CI:0.36 to 0.93, p = 0.02) in school lunch compared to children in comparison schools. More intervention schools (8/11) had healthy eating and physical activity policies compared with comparison schools (2/9). Principals and schools highly valued the approach as a catalyst for broader positive school changes. The cost of the intervention per child was $65 per year.
Conclusion
The fun n healthy in Moreland! intervention did not result in statistically significant differences in BMI z score across trial arms but did result in greater policy implementation, increased parent engagement and resources, improved child self-rated health, increased fruit, vegetable and water consumption, and reduction in sweet drinks. A longer-term follow up evaluation may be needed to demonstrate whether these changes are sustainable and impact on childhood overweight and obesity
Struggling to maintain individuality – Describing the experience of food in nursing homes for people with dementia
Get PDFThis is an open access article under the CC BY-NC-ND license (http://creativecommons.org/licenses/BY-NC-ND/4.0/).Purpose of the study: To describe the food and dining experience of people with cognitive impairment and their family members in nursing homes.
Design and methods: Interviews and focus groups with people with cognitive impairment and their family members (n = 19). Thematic analysis was undertaken using NVivo10 data analysis software package to determine key themes.
Results: The main themes identified tracked a journey for people with cognitive impairment in nursing homes, where they initially sought to have their individual needs and preferences recognised and heard, expressed frustration as they perceived growing barriers to receiving dietary care which met their preferences, and ultimately described a deterioration of the amount of control and choice available to the individual with loss of self-feeding ability and dysphagia.
Implications: Further consideration of how to incorporate individualised dietary care is needed to fully implement person-centred care and support the quality of life of those receiving nursing home care

Temporal variability in shell mound formation at Albatross Bay, northern Australia
Get PDFCopyright: © 2017 Holdaway et al. This is an open access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited.We report the results of 212 radiocarbon determinations from the archaeological excavation of 70 shell mound deposits in the Wathayn region of Albatross Bay, Australia. This is an intensive study of a closely co-located group of mounds within a geographically restricted area in a wider region where many more shell mounds have been reported. Valves from the bivalve Tegillarca granosa (Linnaeus, 1758) were dated. The dates obtained are used to calculate rates of accumulation for the shell mound deposits. These demonstrate highly variable rates of accumulation both within and between mounds. We assess these results in relation to likely mechanisms of shell deposition and show that rates of deposition are affected by time-dependent processes both during the accumulation of shell deposits and during their subsequent deformation. This complicates the interpretation of the rates at which shell mound deposits appear to have accumulated. At Wathayn, there is little temporal or spatial consistency in the rates at which mounds accumulated. Comparisons between the Wathayn results and those obtained from shell deposits elsewhere, both in the wider Albatross Bay region and worldwide, suggest the need for caution when deriving behavioural inferences from shell mound deposition rates, and the need for more comprehensive sampling of individual mounds and groups of mounds
Where’s the Transformation? Unlocking the Potential of Technology-Enhanced Assessment

The effectiveness of using technology for assessment in higher education is still equivocal, particularly in regard to evidence of improvements in student learning. This empirical research explores the affordances that technology offers to assessment for transforming student learning. A systematic literature review, guided by an analytic survey tool, was used to identify and interrogate recent scholarly articles published in 19 international journals. From a total of 1713 articles, 139 articles were identified as being focused on the use of technology for assessment. The analytic tool guided the rigorous exploration of the literature regarding the types of technology being used, the educational goal, the type of assessment, and the degree of “transformation” afforded by the technology. Results showed that, in the sample investigated, TEA is used most frequently for formative peer learning, as part of the task design and feedback stages of the assessment cycle, and that social media has been a major affordance for this. Results are discussed with a view to fostering a future culture of inquiry and scholarship around TEA in higher education
