Tracking of dietary intakes in early childhood : the Melbourne InFANT program

Background/Objectives: The objectives of the present study were to describe food and nutrient intakes in children aged 9 and 18 months, and to assess tracking of intakes between these two ages.

Subjects/Methods: Participants were 177 children of first-time mothers from the control arm of the Melbourne Infant Feeding Activity and Nutrition Trial (InFANT) Program. Dietary intake was collected at 9 and 18 months using three 24 h diet recalls. Tracking was assessed for food and nutrient intakes using logistic regression analysis and estimating partial correlation coefficients, respectively.

Results: Although overall nutrient intakes estimated in this study did not indicate a particular risk of nutrient deficiency, our findings suggest that consumption of energy-dense, nutrient-poor foods occurred as early as 9 months of age, with some of these foods tracking highly over the weaning period. Intakes of healthier foods such as fruits, vegetables, dairy products, eggs, fish and water were also relatively stable over this transition from infancy to toddlerhood, along with moderate tracking for riboflavin, iodine, fibre, calcium and iron. Tracking was low but close to ρ=0.3 for zinc, magnesium and potassium intakes.

Conclusions: The tracking of energy-dense, nutrient-poor foods has important implications for public health, given the development of early eating behaviours is likely to be modifiable. At this stage of life, dietary intakes are largely influenced by the foods parents provide, parental feeding practices and modelling. This study supports the importance of promoting healthy dietary trajectories from infancy.

TOBY : Early intervention in autism through technology

We describe TOBY Playpad, an early intervention program for children with Autism Spectrum Disorder (ASD). TOBY teaches the teacher - the parent - during the crucial period following diagnosis, which often coincides with no access to formal therapy. We reflect on TOBY's evolution from tabletop aid for flashcards to an iPad app covering a syllabus of 326 activities across 51 skills known to be deficient for ASD children, such imitation, joint attention and language. The design challenges unique to TOBY are the need to adapt to marked differences in each child's skills and rate of development (a trait of ASD) and teach parents unfamiliar concepts core to behavioural therapy, such as reinforcement, prompting, and fading. We report on three trials that successively decrease oversight and increase parental autonomy, and demonstrate clear evidence of learning. TOBY's uniquely intertwined Natural Environment Tasks are found to be effective for children and popular with parents. Copyright 2013 ACM.

The constructional geometry of early Javanese temples

The early development of Hindu Javanese architecture can be traced through interpretation of epigraphs, archaeological excavations, and comparison of extant temples with other traditions. However, while many scholars have speculated on connections between Javanese Hindu temples and presumed antecedents in India, these have been made on the basis of visual comparison and epigraphic interpretations. No Indian temple has been conclusively shown to be a model for the earliest Javanese temples. Archaeologist and temple historian Michael Meister has shown in his analysis of the geometric composition of early Hindu temples in South Asia how a ritual sixty-four square mandala was the geometric basis of temple construction during the formative period (fifth to eighth century) of the Indian architectural tradition. Working from an understanding of temple construction sequence as well as their ritual underpinnings, Meister found that the sixtyfour square mandala's dimensions correlate closely to the constructed dimensions at the level of the vedibandha (which corresponds with the plan level of the sanctuary threshold). Furthermore, he shows how the horizontal profile of the cella depends on the number of offsets and the proportional relationships between ech offset based on the subdivision of the sixty-four square grid. The authors have investigated whether a similar compositional basis can be found for the earliest Javanese temples on the Dieng Plateau in the highlands of central Java, despite differences in architectonic and symbolic expression. The analysis of relationships between ritual geometry and actual temple layouts for these buildings has the potential to furthering our understanding of the connections between Hindu temples in Java and those in India.

Investigating the effectiveness of teacher education for early career teachers in diverse settings: analysis of large-scale survey data

‘As researchers and practitioners in the field of teacher education, we seem ill prepared to respond to critics who question the value of professional education for teachers with evidence of our effectiveness’ (Grossman, 2008, p.13). While there are many small-scale, nuanced case studies that speak about the particularities of specific teacher education practices, large scale, systematic, longitudinal studies that can provide rich and comprehensive data about the effectiveness of teacher education are limited (Cochran-Smith & Zeichner, 2005). In Australia, the Studying the Effectiveness of Teacher Education (SETE) project is addressing this gap by investigating the effectiveness of teacher education programs in preparing teachers for the variety of school settings in which they begin their careers. This three-year study utilises large-scale surveys and case studies to construct a deeper understanding of early career teachers’ experiences. It tracks all 2010/2011 teacher education graduates in Queensland and Victoria to investigate the effectiveness of particular characteristics of their teacher education programs in equipping them with the capacity to meet the learning needs of young people in a diverse range of Australian school settings.

This paper will discuss findings from the first of a series of online surveys completed by teacher education graduates in Queensland and Victoria (March-April 2012). Survey data includes teacher demographic information which form independent variables to inform inferential statistical analysis. Beginning teacher responses are mapped against key characteristics of participants' pre-service programs and framed in relation to the key themes of curriculum, pedagogy, assessment, behaviour management, and engagement with school stakeholders and local community. The findings will assist teacher educators design teacher education programs for effective beginning teaching in diverse settings and will also provide an evidentiary basis for policy decisions regarding teacher education and beginning teaching.

Recommendations for and compliance with social restrictions during implementation of school closures in the early phase of the influenza A (H1N1) 2009 outbreak in Melbourne, Australia

Background Localized reactive school and classroom closures were implemented as part of a suite of pandemic containment measures during the initial response to influenza A (H1N1) 2009 in Melbourne, Australia. Infected individuals, and those who had been in close contact with a case, were asked to stay in voluntary home quarantine and refrain from contact with visitors for seven days from the date of symptom onset or exposure to an infected person. Oseltamivir (Tamiflu®) was available for treatment or prophylaxis. Methods We surveyed affected families through schools involved in the closures. Analyses of responses were descriptive. We characterized recommendations made to case and contact households and quantified adherence to guidelines and antiviral therapy. Results Of the 314 respondent households, 51 contained a confirmed case. The prescribed quarantine period ranged from 1-14 days, reflecting logistic difficulties in reactive implementation relative to the stated guidelines. Household-level compliance with the requirement to stay at home was high (84.5%, 95% CI 79.3,88.5) and contact with children outside the immediate family infrequent. Conclusions Levels of compliance with recommendations in our sample were high compared with other studies, likely due to heightened public awareness of a newly introduced virus of uncertain severity. The variability of reported recommendations highlighted the difficulties inherent in implementing a targeted reactive strategy, such as that employed in Melbourne, on a large scale during a public health emergency. This study emphasizes the need to understand how public health measures are implemented when seeking to evaluate their effectiveness.

Preventing maternal and early childhood obesity: the fetal flaw in Australian perinatal care

Almost half of Australian women of child-bearing age are overweight or obese, with a rate of 30–50% reported in early pregnancy. Maternal adiposity is a costly challenge for Australian obstetric care, with associated serious maternal and neonatal complications. Excess gestational weight gain is an important predictor of offspring adiposity into adulthood and higher maternal weight later in life. Current public health and perinatal care approaches in Australia do not adequately address excess perinatal maternal weight or gestational weight gain. This paper argues that the failure of primary health-care providers to offer systematic advice and support regarding women’s weight and related lifestyle behaviours in child-bearing years is an outstanding ‘missed opportunity’ for prevention of inter-generational overweight and obesity. Barriers to action could be addressed through greater attention to: clinical guidelines for maternal weight management for the perinatal period, training and support of maternal health-care providers to develop skills and confidence in raising weight issues with women, a variety of weight management programs provided by state maternal health services, and clear referral pathways to them. Attention is also required to service systems that clearly define roles in maternal weight management and ensure consistency and continuity of support across the perinatal period.

The foreign presence in the early-industrial Haut-Rhin, 1820–22 : a short history from the ‘pre-history’ of immigration to France

An attempt to limit the rights of domiciled foreigners in the Alsatian department of the Haut-Rhin in 1821 provides an opportunity to examine the impact of immigration on early-industrial society and shifting perceptions of the place of foreigners in French society in a period often omitted from histories of immigration. New conceptions of belonging become evident, which demonstrate a turn away from local and subjective bonds to community, towards bonds regulated nationally through nationality law. Imposed in an emerging urban, industrial context, the limitations of rights—on access to the biens communaux and the droit d’affouage—were traditional restrictions of rural society and modes of distinguishing the included from the excluded and were imposed on long-settled foreigners who failed to become naturalized as French citizens. The article reflects on the question why, if the concerns about immigration and industrialization turned on recently arrived foreign workers, these traditional exclusions were imposed on established resident foreigners.

Teaching in the iWorld: developing a repertoire of pedagogical discourse around the usage of touch screen devices in early years classrooms

 Touch-screen devices have been enthusiastically adopted by schools across Australia and Canada. Their ease of use means that they are accessible by very young children, and these children often have free access to these devices in their home, however the devices tend to be ‘domesticated’ in the school context (O’Mara and Laidlaw, 2011). In the short period of their availability, a plethora of educational applications have been developed for these devices. This paper addresses emergent themes from our 2011-2013 Canadian/Australian project, Literacy learning in playful spaces: using multi-modal strategies to develop narrative with young learners, funded by the Canadian Social Sciences and Humanities Research Council (Insight Development Grant). In our analysis of the discourse around the introduction of portable touch screen devices into school literacy classes (published texts, teacher interviews, classroom observations), we noted that much of the public discourse is slanted towards the idea of “teacher-proofing” the curriculum. Initially the teachers we have been working with saw the apps themselves as complete, as doing all the work and the discourse around the devices was around what apps are “best”, and “is there an app for that?” It was only with more experience and time that teachers were able to harness the range of affordances of the devices—their capacity for recording audio, video, pictures etc., and start to categorise the apps themselves. In this paper we suggest ways in which current literacy models might be used to develop a repertoire of pedagogical discourse around these devices, providing language and framings for teachers to think about how these new tools might best be used to enhance literacy teaching and learning.

Changes in the nutritional composition of captive early-mid stage Panulirus ornatus phyllosoma over ecdysis and larval development

Elucidation of the key nutritional requirements for complete larval development of the tropical spiny rock lobster, Panulirus ornatus, presents a major challenge for the development of robust commercial aquaculture for this crustacean. As a foundation study in this area, the chemical composition of early-mid stage P. ornatus phyllosoma (Stages I-VI) receiving a novel formulated diet was analysed immediately prior and post-ecdysis to provide insight into the crude nutritional trends during the larval development cycle. From the onset of moulting, cyclical patterns were evident in the proximate composition of phyllosoma, resulting in substantial restructuring between the pre- and post-moult stages of the moult cycle. Proportions of protein, lipid and ash were high at the premoult stage, reflecting growth and nutrient accumulation over the intermoult period, and reduced at the post-moult stage, reflecting the large uptake of water to facilitate subsequent growth. Polar lipid was the dominant lipid class, accounting for >. 90% of the total lipid content. Conversely, triacylglycerol concentrations were low (<. 5%), despite being the principal lipid class available in the formulated diet. Likewise, despite receiving high concentrations of eicosapentaenoic acid (EPA, 20:5n-3) and docosahexaenoic acid (DHA, 22:6n-3) (9.2 and 7.6% of the dietary lipid source, respectively), levels of these fatty acids were comparatively low in phyllosoma (3.4 and 4.7%, respectively). In contrast, there is selective deposition of these fatty acids in wild caught phyllosoma. This finding suggests a poor assimilation of triacylglycerols by captive larvae and highlights the importance of future investigations into alternative sources of EPA and DHA. Ultimately, this study provides insight into the nutritional requirements of phyllosoma, providing valuable knowledge on diet formulation for commercially viable hatchery production of spiny rock lobsters. © 2014 Elsevier B.V.

The effects of pre-digested protein sources on the performance of early-mid stage Panulirus ornatus phyllosoma

Phyllosoma of the tropical spiny rock lobster, Panulirus ornatus, possess a rudimentary digestive system with a limited capacity to digest large protein molecules. As such, to foster the successful aquaculture of this species, research into dietary requirements should place a focus on feed ingredients aligned with digestive capacity. Thus, the aim of the present study was to assess the effects of two protein pre-digestion treatments: acid denaturation and enzyme hydrolysis, on a regular fishmeal ingredient in a novel formulated diet for early-mid stage P. ornatus phyllosoma (Stages III-VIII). Three iso-nitrogenous, iso-lipidic and iso-energetic diets were formulated with 100% of protein originating from intact fishmeal (IFM), acid-denatured fishmeal (DFM) or enzyme hydrolysed fishmeal (HFM) and fed to early-mid stage phyllosoma for a period of 35-days. Growth performance metrics were all significantly higher in phyllosoma receiving the HFM treatment compared to the DFM and IFM treatments. Phyllosoma fed the HFM diet also had the most advanced development stages, with a significantly greater proportion of individuals reaching Stage VII (2). No significant differences were detectable in either the protein-bound or FAA composition of phyllosoma across all treatments, suggesting that the superior growth performance of the HFM fed phyllosoma was the result of an increased abundance of intermediate, shorter chain dietary peptides. The present study suggests that enzyme hydrolysed fishmeal is a superior protein ingredient for artificial diets and most closely resembles the requisite dietary protein format for P. ornatus phyllosoma.

Individual and sex-specific differences in intrinsic growth rate covary with consistent individual differences in behaviour

1.The evolutionary causes of consistent individual differences in behavior are currently a source of debate. A recent hypothesis suggests that consistent individual differences in life-history productivity (growth and/or fecundity) may covary with behavioral traits that contribute to growth-mortality trade-offs, such as risk-proneness (boldness) and foraging activity (voraciousness). It remains unclear, however, to what extent individual behavioral and life-history profiles are set early in life, or are a more flexible result of specific environmental or developmental contexts that allow bold and active individuals to acquire more resources. 2.Longitudinal studies of individually housed animals under controlled conditions can shed light on this question. Since growth and behaviour can both vary within individuals (they are labile), studying between-individual correlations in behaviour and growth rate requires repeated scoring for both variables over an extended period of time. However, such a study has not yet been done. 3.Here, we repeatedly measured individual mass 7-times each, boldness 40-times each, and voracity 8-times each during the first four months of life on 90 individually-housed crayfish (Cherax destructor). Animals were fed ad-libitum, generating a context where individuals can express their intrinsic growth rate (i.e. growth capacity), but in which bold and voracious behaviour is not necessary for high resource acquisition (crayfish can and do hoard food back to their burrow). 4.We show that individuals that were consistently bold over time during the day were also bolder at night, were more voracious, and maintained higher growth rates over time than shy individuals. Independent of individual differences, we also observed that males were faster growing, bolder, and more voracious than females. 5.Our findings imply that associations between bold behaviour and fast growth can occur in unlimited food contexts where there is no necessary link between bold behaviour and resource acquisition - offering support for the 'personality- productivity' hypothesis. We suggest future research should study links between consistent individual differences in behaviour and life-history under a wider range of contexts, in order to shed light on the role of biotic and abiotic conditions in the strength, direction and stability of their covariance.

The films of John Hughes: a history of independent screen production in Australia

ABSTRACTIn The Films of John Hughes: A history of independent screen production in Australia filmmaker and academic John Cumming tells the ongoing story of Hughes’ work illustrating the delicate balance of individual, collective and corporate agendas that many contemporary artists need to negotiate. This story begins in the 1960s with a generation of intelligent, socially engaged young people who challenge established power structures, conventions and stereotypes in art, politics and the media. Experiments were being made with grassroots democracy, with new social formations and new ways of seeing and communicating. The book also pays attention to earlier periods of cultural and political activism that captured Hughes’ imagination in the 1970s and became the subject of a number of his films over a period of nearly forty years. Through these films Cumming traces the outline of post-war film culture and production in Melbourne from the 1940s and sets this history within the context of international trends in independent filmmaking throughout the 20th Century and into the 21st.The work of an independent filmmaker has always included a great deal more than directing films. Working in an artisanal mode, he or she often performs, or has a hand in, every aspect of craft at the same time as engaging in discussion and organisation around the wider sphere of screen culture and industry. In addition to having proficiency as a producer, photographer, sound recordist, editor, distributor and exhibitor of films, there is research, organisation, lobbying, entrepreneurship and mentoring to be done. As an independent producer-director, John Hughes has engaged in all of these activities – often simultaneously. He is also a scholar, writer, organiser, activist and teacher. As a television bureaucrat he was both eminent and innovative, and through his filmmaking he has become a leading historian of Australian documentary cinema. ‘… that view – that art and politics are inherently at odds – is still lurking around. It is at the heart of cultural conservatism; and John Hughes’s film-making, from the 1970s to the present, confounds its proponents. His cinema is at once crowded, detailed, elegant and absolutely lucid; at the same time, it is shot through with political and historical understandings.’ Sylvia Lawson, ‘Such a Bloody Wonderful Place’, Inside Story, 28 April 2013.

Mental Health First Aid: an international programme for early intervention.

AIM: To describe the development of the Mental Health First Aid (MHFA) programme in Australia, its roll-out in other countries and evaluation studies which have been carried out. METHODS: A description of the programme's development and evaluation, its cultural adaptations and its dissemination in seven countries. RESULTS: The programme was developed in Australia in 2001. By the end of 2007, there were 600 instructors and 55,000 people trained as mental health first aiders. A number of evaluations have been carried out, including two randomized controlled trials that showed changes in knowledge, attitudes and first aid behaviours. Special adaptations of the course have been rolled out for Aboriginal and Torres Strait Islander peoples and some non-English speaking immigrant groups. The course has spread to seven other countries with varying degrees of penetration. In all countries, the programme has been initially supported by government funding. Independent evaluations have been carried out in Scotland and Ireland. CONCLUSIONS: The concept of first aid by the public for physical health crises is familiar in many countries. This has made it relatively easy to extend this approach to early intervention by members of the public for mental disorders and crises. Through MHFA training, the whole of a community can assist formal mental health services in early intervention for mental disorders.

The inter-relationship between depressive, anxiety and stress symptoms in fathers during the antenatal period

Objective: The aim of this study was to examine whether depressive symptoms predict anxiety and stress or whether anxiety and stress precede depressive symptoms in fathers during the antenatal period. Background: The findings of previous studies suggest that there is an association between paternal depression, anxiety and stress during the antenatal period. However, the temporal inter-relationship between these variables has yet to be investigated. Method: Data were collected from 150 expectant couples at approximately 18, 25 and 33 weeks’ gestation. Results: After accounting for the relative stability of depression, anxiety and stress over time, for men higher levels of anxiety earlier in pregnancy predicted higher levels of depression and stress in middle pregnancy, which predicted higher depression during late pregnancy. A similar relationship remained after partialling out the effects of partner’s depression, perceived social support and sleep quality. Further analyses also revealed significant differences in the manifestation of distress symptoms between men and women, but not between first-time and non-first-time fathers. Conclusion: Our findings indicated a possible inter-relationship between depression, anxiety and stress for men antenatally. Our findings also showed that men who reported elevated depression, anxiety and stress earlier in the antenatal period also reported elevated symptomology at later time points. Finally, the current findings revealed that antenatal paternal stress may play a key role in the development of depression and anxiety later in pregnancy. Therefore, it may be important to screen for early levels of antenatal stress in men, as well as depression and anxiety.
