Is there an app for that? Looking at possibilities and challenges of digital tools for literacy education

 Portable electronic devices such as the iPad are increasingly taking a place in contemporary childhood experiences including those of schooling (O'Mara & Laidlaw, 2011). As digital media theorists suggest, such new tools invite both "hope and fear" (Gee and Hayes, 2011, p.4), consistent with literacy innovations across history. In both Canada and Australia, educational stakeholders are looking to touch screen devices as having much promise, particularly within literacy education. This paper presentation examines the possibilities as well as the challenges and imagines the future of such digital tools within literacy education, looking at experiences and perspectives in Canada and Australia.
We take a qualitative ecological mode of inquiry approach to our data collection and analysis, drawing on complexity thinking (Davis & Sumara, 2006) to bring our multiple points of view together as diversely positioned educators. Within our individual sites, each author has collected data as a part of longer-term research projects. In this paper presentation we compare and contrast these data sets, attending to significant intersections and juxtaposing issues of culture and globalization. Within this mode of inquiry we value the particularity of the individual contexts, and locate them alongside one another in a larger bricolage (Johnson, 2010).
We examined observational data, documents and artifacts using Freebody and Luke's (1990) four resources model and the further adaptions of this model (see e.g. Luke & Freebody, 1999) to understand how touch screen devices are being used and positioned as literacy tools. We have engaged in collaborative data analysis, often working 'together' using digital tools ourselves to enable collective conversations. For example, we have used Facetime on iPads and laptops, Skype and email to facilitate collective analyses. We applied iterative and recursive analyses to uncover reoccurring themes both within and across sites and artifacts.
As our paper will elaborate, mobile touch screen devices such as iPads are widely being taken up in educational settings, and regarded as having the possibility to shift teaching and learning in new directions, as "paradigm breakers" (p. 4, Gov't of AB, 2011). As personal, mobile devices, these tools present challenges that require educators to think differently about learning and teaching. Our paper also addresses the opportunities and affordances that iPads might offer to learners, as having the potential for students to engage in playful exploration, and in the role of designers, creators, and producers, rather than as passive recipients.

Is iron and zinc nutrition a concern for vegetarian infants and young children in industrialized countries?

Well-planned vegetarian diets are considered adequate for all stages of the life cycle, despite limited data on the zinc status of vegetarians during early childhood. The bioavailability of iron and zinc in vegetarian diets is poor because of their higher content of absorption inhibitors such as phytate and polyphenols and the absence of flesh foods. Consequently, children as well as adult vegetarians often have lower serum ferritin concentrations than omnivores, which is indicative of reduced iron stores, despite comparable intakes of total iron; hemoglobin differences are small and rarely associated with anemia. However, data on serum zinc concentrations, the recommended biomarker for identifying population groups at elevated risk of zinc deficiency, are sparse and difficult to interpret because recommended collection and analytic procedures have not always been followed. Existing data indicate no differences in serum zinc or growth between young vegetarian and omnivorous children, although there is some evidence of low serum zinc concentrations in vegetarian adolescents. Some vegetarian immigrants from underprivileged households may be predisposed to iron and zinc deficiency because of nondietary factors such as chronic inflammation, parasitic infections, overweight, and genetic hemoglobin disorders. To reduce the risk of deficiency, the content and bioavailability of iron and zinc should be enhanced in vegetarian diets by consumption of fortified cereals and milk, by consumption of leavened whole grains, by soaking dried legumes before cooking and discarding the soaking water, and by replacing tea and coffee at meals with vitamin C-rich drinks, fruit, or vegetables. Additional recommended practices include using fermented soy foods and sprouting at least some of the legumes consumed. Fortified foods can reduce iron deficiency, but whether they can also reduce zinc deficiency is less certain. Supplements may be necessary for vegetarian children following very restricted vegan diets.

Associations between dietary iron and zinc intakes, and between biochemical iron and zinc status in women

Iron and zinc are found in similar foods and absorption of both may be affected by food compounds, thus biochemical iron and zinc status may be related. This cross-sectional study aimed to: (1) describe dietary intakes and biochemical status of iron and zinc; (2) investigate associations between dietary iron and zinc intakes; and (3) investigate associations between biochemical iron and zinc status in a sample of premenopausal women aged 18–50 years who were recruited in Melbourne and Sydney, Australia. Usual dietary intakes were assessed using a 154-item food frequency questionnaire (n = 379). Iron status was assessed using serum ferritin and hemoglobin, zinc status using serum zinc (standardized to 08:00 collection), and presence of infection/inflammation using C-reactive protein (n = 326). Associations were explored using multiple regression and logistic regression. Mean (SD) iron and zinc intakes were 10.5 (3.5) mg/day and 9.3 (3.8) mg/day, respectively. Median (interquartile range) serum ferritin was 22 (12–38) μg/L and mean serum zinc concentrations (SD) were 12.6 (1.7) μmol/L in fasting samples and 11.8 (2.0) μmol/L in nonfasting samples. For each 1 mg/day increase in dietary iron intake, zinc intake increased by 0.4 mg/day. Each 1 μmol/L increase in serum zinc corresponded to a 6% increase in serum ferritin, however women with low serum zinc concentration (AM fasting < 10.7 μmol/L; AM nonfasting < 10.1 μmol/L) were not at increased risk of depleted iron stores (serum ferritin <15 μg/L; p = 0.340). Positive associations were observed between dietary iron and zinc intakes, and between iron and zinc status, however interpreting serum ferritin concentrations was not a useful proxy for estimating the likelihood of low serum zinc concentrations and women with depleted iron stores were not at increased risk of impaired zinc status in this cohort.

Strategies for Using the Safe Schools Hub: A ‘One-stop Resource Shop’ for Developing Safe and Supportive School Cultures

The Safe Schools Hub is an online portal created by the Australian Government to support the National Safe Schools Framework. It includes extensive resources for leaders, teachers, specialist staff, parents and students. This presentation will highlight a variety of practical strategies based on these resources that schools can use as they continue to develop safe and supportive school cultures. In particular there will be a focus on resource-based approaches that can assist leaders with data collection and change processes, specific resources that can be incorporated into professional development seminars for staff and resources to direct and support strategies for parent education sessions.

A proposed approach to systematically identify and monitor the corporate political activity of the food industry with respect to public health using publicly available information.

Unhealthy diets represent one of the major risk factors for non-communicable diseases. There is currently a risk that the political influence of the food industry results in public health policies that do not adequately balance public and commercial interests. This paper aims to develop a framework for categorizing the corporate political activity of the food industry with respect to public health and proposes an approach to systematically identify and monitor it. The proposed framework includes six strategies used by the food industry to influence public health policies and outcomes: information and messaging; financial incentive; constituency building; legal; policy substitution; opposition fragmentation and destabilization. The corporate political activity of the food industry could be identified and monitored through publicly available data sourced from the industry itself, governments, the media and other sources. Steps for country-level monitoring include identification of key food industry actors and related sources of information, followed by systematic data collection and analysis of relevant documents, using the proposed framework as a basis for classification of results. The proposed monitoring approach should be pilot tested in different countries as part of efforts to increase the transparency and accountability of the food industry. This approach has the potential to help redress any imbalance of interests and thereby contribute to the prevention and control of non-communicable diseases.

Improving schools: productive tensions between the local, the systemic and the global

This unique book explores school improvement policy – from its translation into national contexts and school networks to its implementation in leader and teacher practices in individual schools and classrooms within this network of schools and its impact on students’ learning. It draws on multiple conceptual and theoretical resources to explore the complexities attached to a school improvement process in a network of schools in Australia. These conceptual and theoretical resources include discourse, practice, representation and network, concepts common to both policy research as well as studies of leadership and classroom practice. They lead to a more detailed understanding of the intersections between educational policy and intervention processes, and the complex reality of school processes and teaching practices. In the book we trace the implementation of school improvement policies through its multiple phases, levels and contexts. Our data-collection and analysis methods draw on a variety of perspectives in the way different players perceive their roles and the nature of the initiative and the ways in which these intersect. The research findings are used to seek productive approaches to school improvement that combine policy integrity with local flexibility. The book contributes to the school improvement literature through its exploration of tensions between global and systemic settings and local practices and histories.

[Soccer collection - photo index]

The Soccer collection contains the Laurie Schwab collection and the Les Shorrock collection. Both collections were donated in 2003 and reflect soccer in Australia in the modern era. Laurie Schwab was a journalist and editor and his collection includes numerous clippings and photographs relating to soccer. Les Shorrock was a photographer who worked for the Melbourne "Age" and as a freelancer. His collection consists of the photographs he took of soccer players and teams whilst he was freelancing, whilst he was part of "Soccer Action" from 1976 to 1987 and whilst working for the "Age" from 1987 to 1995.
The Photo Index provides a list of the various photographs in the collection.

Nurse-led titration of angiotensin converting enzyme inhibitors, beta-adrenergic blocking agents, and angiotensin receptor blockers for people with heart failure with reduced ejection fraction

BACKGROUND: Heart failure is associated with high mortality and hospital readmissions. Beta-adrenergic blocking agents, angiotensin converting enzyme inhibitors (ACEIs), and angiotensin receptor blockers (ARBs) can improve survival and reduce hospital readmissions and are recommended as first-line therapy in the treatment of heart failure. Evidence has also shown that there is a dose-dependent relationship of these medications with patient outcomes. Despite this evidence, primary care physicians are reluctant to up-titrate these medications. New strategies aimed at facilitating this up-titration are warranted. Nurse-led titration (NLT) is one such strategy. OBJECTIVES: To assess the effects of NLT of beta-adrenergic blocking agents, ACEIs, and ARBs in patients with heart failure with reduced ejection fraction (HFrEF) in terms of safety and patient outcomes. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials in the Cochrane Library (CENTRAL Issue 11 of 12, 19/12/2014), MEDLINE OVID (1946 to November week 3 2014), and EMBASE Classic and EMBASE OVID (1947 to 2014 week 50). We also searched reference lists of relevant primary studies, systematic reviews, clinical trial registries, and unpublished theses sources. We used no language restrictions. SELECTION CRITERIA: Randomised controlled trials (RCTs) comparing NLT of beta-adrenergic blocking agents, ACEIs, and/or ARBs comparing the optimisation of these medications by a nurse to optimisation by another health professional in patients with HFrEF. DATA COLLECTION AND ANALYSIS: Two review authors (AD & JC) independently assessed studies for eligibility and risk of bias. We contacted primary authors if we required additional information. We examined quality of evidence using the GRADE rating tool for RCTs. We analysed extracted data by risk ratio (RR) with 95% confidence interval (CI) for dichotomous data to measure effect sizes of intervention group compared with usual-care group. Meta-analyses used the fixed-effect Mantel-Haenszel method. We assessed heterogeneity between studies by Chi(2) and I(2). MAIN RESULTS: We included seven studies (1684 participants) in the review. One study enrolled participants from a residential care facility, and the other six studies from primary care and outpatient clinics. All-cause hospital admission data was available in four studies (556 participants). Participants in the NLT group experienced a lower rate of all-cause hospital admissions (RR 0.80, 95% CI 0.72 to 0.88, high-quality evidence) and fewer hospital admissions related to heart failure (RR 0.51, 95% CI 0.36 to 0.72, moderate-quality evidence) compared to the usual-care group. Six studies (902 participants) examined all-cause mortality. All-cause mortality was also lower in the NLT group (RR 0.66, 95% CI 0.48 to 0.92, moderate-quality evidence) compared to usual care. Approximately 27 deaths could be avoided for every 1000 people receiving NLT of beta-adrenergic blocking agents, ACEIs, and ARBs. Only three studies (370 participants) reported outcomes on all-cause and heart failure-related event-free survival. Participants in the NLT group were more likely to remain event free compared to participants in the usual-care group (RR 0.60, 95% CI 0.46 to 0.77, moderate-quality evidence). Five studies (966 participants) reported on the number of participants reaching target dose of beta-adrenergic blocking agents. This was also higher in the NLT group compared to usual care (RR 1.99, 95% CI 1.61 to 2.47, low-quality evidence). However, there was a substantial degree of heterogeneity in this pooled analysis. We rated the risk of bias in these studies as high mainly due to a lack of clarity regarding incomplete outcome data, lack of reporting on adverse events associated with the intervention, and the inability to blind participants and personnel. Participants in the NLT group reached maximal dose of beta-adrenergic blocking agents in half the time compared with participants in usual care. Two studies reported on adverse events; one of these studies stated there were no adverse events, and the other study found one adverse event but did not specify the type or severity of the adverse event. AUTHORS' CONCLUSIONS: Participants in the NLT group experienced fewer hospital admissions for any cause and an increase in survival and number of participants reaching target dose within a shorter time period. However, the quality of evidence regarding the proportion of participants reaching target dose was low and should be interpreted with caution. We found high-quality evidence supporting NLT as one strategy that may improve the optimisation of beta-adrenergic blocking agents resulting in a reduction in hospital admissions. Despite evidence of a dose-dependent relationship of beta-adrenergic blocking agents, ACEIs, and ARBs with improving outcomes in patients with HFrEF, the translation of this evidence into clinical practice is poor. NLT is one strategy that facilitates the implementation of this evidence into practice.

Dietary salt intake and discretionary salt use in two general population samples in Australia: 2011 and 2014

The limited Australian measures to reduce population sodium intake through national initiatives targeting sodium in the food supply have not been evaluated. The aim was, thus, to assess if there has been a change in salt intake and discretionary salt use between 2011 and 2014 in the state of Victoria, Australia. Adults drawn from a population sample provided 24 h urine collections and reported discretionary salt use in 2011 and 2014. The final sample included 307 subjects who participated in both surveys, 291 who participated in 2011 only, and 135 subjects who participated in 2014 only. Analysis included adjustment for age, gender, metropolitan area, weekend collection and participation in both surveys, where appropriate. In 2011, 598 participants: 53% female, age 57.1(12.0)(SD) years and in 2014, 442 participants: 53% female, age 61.2(10.7) years provided valid urine collections, with no difference in the mean urinary salt excretion between 2011: 7.9 (7.6, 8.2) (95% CI) g/salt/day and 2014: 7.8 (7.5, 8.1) g/salt/day (p = 0.589), and no difference in discretionary salt use: 35% (2011) and 36% (2014) reported adding salt sometimes or often/always at the table (p = 0.76). Those that sometimes or often/always added salt at the table and when cooking had 0.7 (0.7, 0.8) g/salt/day (p = 0.0016) higher salt excretion. There is no indication over this 3-year period that national salt reduction initiatives targeting the food supply have resulted in a population reduction in salt intake. More concerted efforts are required to reduce the salt content of manufactured foods, together with a consumer education campaign targeting the use of discretionary salt.

Barriers to primary care clinician adherence to clinical guidelines for the management of low back pain: a systematic review and meta-synthesis of qualitative studies

INTRODUCTION: Despite the availability of evidence-based guidelines for the management of low back pain that contain consistent messages, large evidence-practice gaps in primary care remain.

OBJECTIVES: To perform a systematic review and meta-synthesis of qualitative studies that have explored primary care clinicians' perceptions and beliefs about guidelines for low back pain, including perceived enablers and barriers to guideline adherence.

METHODS: Studies investigatingperceptions and beliefs about low back pain guidelines were included if participants were primary care clinicians and qualitative methods had been used for both data collection and analysis. We searched major databases up to July 2014. Pairs of reviewers independently screened titles and abstracts, extracted data, appraised method quality using the CASP checklist, conducted thematic analysis and synthesized the results in narrative format.

RESULTS: Seventeen studies, with a total of 705 participants, were included. We identified three key emergent themes and eight subthemes: (1) guideline implementation and adherence beliefs and perceptions; (2) maintaining the patient-clinician relationship with imaging referrals; (3) barriers to guideline implementation. Clinicians believed that guidelines were categorical, prescriptive and constrained professional practice; however popular clinical practices superseded the guidelines. Imaging referrals were used to manage consultations and to obtain definitive diagnoses. Clinicians' perceptions reflected a lack of content knowledge and understanding of how guidelines are developed.

DISCUSSION: Addressing misconceptions and other barriers to uptake of evidence-based guidelines for managing low back pain is needed to improve knowledge transfer and close the evidence-practice gap in the treatment of this common condition.

Vitamins D and A can be successfully measured by LC-MS/MS in cord blood diluted plasma

OBJECTIVES: In widely used protocols for the collection and isolation of cord blood mononuclear cells, investigators are left with substantial volumes of diluted plasma which could be used for other measurements. The aim of this study was to ascertain the validity of umbilical cord blood (UCB) diluted plasma samples for vitamin D, A and E analysis compared to UCB serum samples. DESIGN & METHODS: Twenty UCB matched samples of diluted plasma and serum were collected. The samples were analysed by two liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods on two separate occasions. RESULTS: The results of 25(OH)D3 obtained by the two laboratories demonstrated close agreement with a mean difference of 0.14nmol/L [95% confidence interval (95% CI), -6.8 to 7.1]. Both methods demonstrate close agreement for 25(OH)D3 in UCB serum versus diluted UCB plasma; mean difference 2.2nmol/L [95% CI, -9.5 to 13.9] and 4.1nmol/L [95% CI, -14.5 to 6.1] for the results from Lab A and Lab B, respectively. Vitamin A was quantified by Lab A in UCB serum and diluted UCB plasma; mean difference 0.07μmol/L [95% CI, -0.41 to 0.28]. Results of 25(OH)D3 epimer and vitamin E in the diluted UCB plasma were below the limit of quantification, and could not be compared with UCB serum. CONCLUSIONS: Diluted UCB plasma can be used for the quantification of retinol and 25(OH)D3 by LC-MS/MS. By contrast, quantification of 25(OH)D3 epimer and vitamin E in diluted UCB plasma is not supported by this study due to limitations in analytical sensitivity.

Southern anthropology - a history of Fison and Howitt's Kamilaroi and Kurnai

From far-flung sites in Australia and the Pacific Islands, Lorimer Fison and A. W. Howitt produced the landmark study Kamilaroi and Kurnai (1880). Their book revealed the complexity of Aboriginal and Pacific Island societies and changed the course of anthropology in the early years of the discipline. Using archival sources and an innovative approach, Southern Anthropology explores the research, writing and reception of Kamilaroi and Kurnai. Historical chapters track Fison and Howitt's collection and analysis of anthropological material in the context of raging debates about the evolution of humans. This narrative is interspersed with an introduction to the kinship and social organisation of Aboriginal and Pacific Island people that highlight the enduring value of Fison and Howitt's methods and the resurgence of their questions in contemporary anthropology. Southern Anthropology is designed to be read across disciplinary boundaries.

BioKin: an ambulatory platform for gait kinematic and feature assessment

A platform to move gait analysis, which is normally restricted to a clinical environment in a well-equipped gait laboratory, into an ambulatory system, potentially in non-clinical settings is introduced. This novel system can provide functional measurements to guide therapeutic interventions for people requiring rehabilitation with limited access to such gait laboratories. BioKin system consists of three layers: a low-cost wearable wireless motion capture sensor, data collection and storage engine, and the motion analysis and visualisation platform. Moreover, a novel limb orientation estimation algorithm is implemented in the motion analysis platform. The performance of the orientation estimation algorithm is validated against the orientation results from a commercial optical motion analysis system and an instrumented treadmill. The study results demonstrate a root-mean-square error less than 4° and a correlation coefficient more than 0.95 when compared with the industry standard system. These results indicate that the proposed motion analysis platform is a potential addition to existing gait laboratories in order to facilitate gait analysis in remote locations.

A comparison of collection techniques for gene expression analysis of human oral taste tissue

Variability in human taste perception is associated with both genetic and environmental factors. The influence of taste receptor expression on this variability is unknown, in part, due to the difficulty in obtaining human oral tissue that enables quantitative expression measures of taste genes. In a comparison of six current techniques (Oragene RNeasy Kit, Isohelix swab, Livibrush cytobrush, tongue saliva, cheek saliva collection, and fungiform papillae biopsy), we identify the fungiform papillae biopsy is the optimal sampling technique to analyse human taste gene expression. The fungiform papillae biopsy resulted in the highest RNA integrity, enabling amplification of all the assessed taste receptor genes (TAS1R1, TAS1R2, TAS1R3, SCNN1A and CD36) and taste tissue marker genes (NCAM1, GNAT3 and PLCβ2). Furthermore, quantitative expression was observed in a subset of taste genes assessed from the saliva collection techniques (cheek saliva, tongue saliva and Oragene RNA kit). These saliva collection techniques may be useful as a non-invasive alternative sampling technique to the fungiform papillae biopsy. Identification of the fungiform papillae biopsy as the optimal collection method will facilitate further research into understanding the effect of gene expression on variability in human taste perception.

How reliable is internet-based self-reported identity, socio-demographic and obesity measures in European adults?

In e-health intervention studies, there are concerns about the reliability of internet-based, self-reported (SR) data and about the potential for identity fraud. This study introduced and tested a novel procedure for assessing the validity of internet-based, SR identity and validated anthropometric and demographic data via measurements performed face-to-face in a validation study (VS). Participants (n = 140) from seven European countries, participating in the Food4Me intervention study which aimed to test the efficacy of personalised nutrition approaches delivered via the internet, were invited to take part in the VS. Participants visited a research centre in each country within 2 weeks of providing SR data via the internet. Participants received detailed instructions on how to perform each measurement. Individual's identity was checked visually and by repeated collection and analysis of buccal cell DNA for 33 genetic variants. Validation of identity using genomic information showed perfect concordance between SR and VS. Similar results were found for demographic data (age and sex verification). We observed strong intra-class correlation coefficients between SR and VS for anthropometric data (height 0.990, weight 0.994 and BMI 0.983). However, internet-based SR weight was under-reported (Δ -0.70 kg [-3.6 to 2.1], p < 0.0001) and, therefore, BMI was lower for SR data (Δ -0.29 kg m(-2) [-1.5 to 1.0], p < 0.0001). BMI classification was correct in 93 % of cases. We demonstrate the utility of genotype information for detection of possible identity fraud in e-health studies and confirm the reliability of internet-based, SR anthropometric and demographic data collected in the Food4Me study.
