The current political context necessitates discussions of social justice within education, and here we bring together early childhood professionals from a variety of perspectives to become part of the important debates that must be had. This special issue of Contemporary Issues in Early Childhood was first conceived at a meeting of academics interested in social justice in early childhood education in Albury, NSW, Australia. All of the editors are members of the Social Justice strand of the ARC Funded Excellence in Research in Early Years Education Collaborative Research Network (CRN), which is led by Charles Sturt University in partnership with Queensland University of Technology and Monash University. Some of the authors in this issue are also members of this research network, but their work is presented here with that of others from a variety of contexts. We believe that the combination of perspectives taken challenges old thinking about social justice in early years education in innovative ways.

Using a state, pressure, response framework, we provide an evidence-based reflection on environmental outcomes in Australia and New Zealand across the domains of climate change, biodiversity, freshwater and marine management, emphasising the role of Indigenous and business perspectives. Significant developments have occurred in the past 20 years through affirmation of Indigenous rights and responsibilities. Responses to climate change have tended to emphasise passive risk management with unclear outcomes. Despite meeting biodiversity protection targets, outcomes are worsening, suggesting a need to challenge the dualistic preservation/production land categorisations. In freshwater and marine management, a mix of collaborative and market-based responses has emerged, although their efficacy remains untested. A reliance on voluntary approaches by business makes critical assessment of progress difficult. Thus, despite strong progress in some areas, the adaptiveness of environmental management remains limited, and many indicators suggest continuing decline in environmental condition. Our responses have been largely pacifying in nature, leading to perverse outcomes and failure to acknowledge alternatives that might address deteriorating environmental conditions. A shift is needed towards deliberative policy experimentation that truly values the application of novel and diversified approaches and facilitates integrated learning across environmental domains.

The aim of this study was to elucidate the thermophysiological effects of wearing lightweight non-military overt and covert personal body armour (PBA) in a hot and humid environment. Eight healthy males walked on a treadmill for 120 min at 22% of their heart rate reserve in a climate chamber simulating 31 °C (60%RH) wearing either no armour (control), overt or covert PBA in addition to a security guard uniform, in a randomised controlled crossover design. No significant difference between conditions at the end of each trial was observed in core temperature, heart rate or skin temperature (P > 0.05). Covert PBA produced a significantly greater amount of body mass change (−1.81 ± 0.44%) compared to control (−1.07 ± 0.38%, P = 0.009) and overt conditions (−1.27 ± 0.44%, P = 0.025). Although a greater change in body mass was observed after the covert PBA trial; based on the physiological outcome measures recorded, the heat strain encountered while wearing lightweight, non-military overt or covert PBA was negligible compared to no PBA. Practitioner summary The wearing of bullet proof vests or body armour is a requirement of personnel engaged in a wide range of occupations including police, security, customs and even journalists in theatres of war. This randomised controlled crossover study is the first to examine the thermophysiological effects of wearing lightweight non-military overt and covert personal body armour (PBA) in a hot and humid environment. We conclude that the heat strain encountered while wearing both overt and covert lightweight, non-military PBA was negligible compared to no PBA.

In this chapter we describe a critical fairytales unit taught to 4.5 to 5.5 year olds in a context of intensifying pressure to raise literacy achievement. The unit was infused with lessons on reinterpreted fairytales followed by process drama activities built around a sophisticated picture book, Beware of the Bears (MacDonald, 2004). The latter entailed a text analytic approach to critical literacy derived from systemic functional linguistics (Halliday, 1978; Halliday & Matthiessen, 2004). This approach provides a way of analysing how words and discourse are used to represent the world in a particular way and shape reader relations with the author in a particular field (Janks, 2010).

In what follows, I draw attention to understandings about the teaching of Standard Australian English spelling developed by being immersed in the URL project site for four years though sharing professional dialogue with teachers and educators and entering into informal conversations with some of the students and their parents. My understandings focus on the potential and problematics of oft-used generic spelling programs and approaches for student cohorts marked by social, cultural and linguistic diversity. This article concludes by considering two possible extensions to the word study approach that may have utility for working with middle years students from diverse backgrounds: creating a discursive ‘Third Space’ that overtly recognises students’ language experiences and the technique of colour blocking to create a visual stress.

Purpose The purpose of this study is to examine the prevalence, sociodemographic and clinical predictors, and physical and psychosocial correlates of unmet needs among women 3–5 years following treatment for endometrial cancer. Methods Women with endometrial cancer completed a survey around the time of diagnosis and again 3–5 years later. The follow-up survey asked women about their physical and psychosocial functioning and supportive care needs (CaSUN). Multivariable-adjusted logistic regression identified the predictors and correlates of women’s unmet needs 3–5 years after diagnosis. Results Of the 629 women who completed the cancer survivors’ unmet needs measure (CaSUN), 24 % (n = 153) women reported one or more unmet supportive care needs in the last month. Unmet needs at 3–5 years post-diagnosis were predicted by younger age (OR = 4.47; 95 % CI: 2.09–9.56) and advanced disease stage at diagnosis (OR = 2.47; 95 % CI: 1.38–4.45) and correlated with greater cancer symptoms (OR = 1.78; 95 % CI: 1.05–3.02), lower limb swelling (OR = 2.50; 95 % CI: 1.51–4.15), symptoms of anxiety (OR = 2.21; 95 % CI: 1.31–3.72), and less availability of social support (OR = 3.42; 95 % CI: 1.92–6.11). Women with a history of comorbidities (OR = 0.47; 95 % CI: 0.27–0.82) and those living in a rural area at the time of diagnosis (OR = 0.56; 95 % CI: 0.34–0.92) were less likely to report unmet needs. Conclusions Sociodemographic, health, and psychosocial factors seem important for identifying women who will or will not have unmet needs several years following endometrial cancer. Longitudinal assessments of people’s needs over the course of their cancer trajectory may be an effective way to identify areas that should receive further attention by health providers.

Background Few studies have examined the long-term changes experienced by women treated for endometrial cancer. Objective The objectives of this study were to describe what women perceived important to their lifestyle and quality of life in the years following their diagnosis and to provide new insights that might inform healthcare practice. Methods This was a thematic analysis of 237 open-ended comments from Australian women diagnosed with endometrial cancer 3 to 5 years previously. Results We identified 3 main themes: (1) personal change, in which women spoke about cancer as permanently altering their lives in mostly negative but sometimes positive ways; (2) continuity of former life, which described both the minimal impact of cancer on women's lives and identities and the difficulties negotiating this within the dominant "cancer survivorship" culture; (3) social support, where women wrote about how the quality of their relationships shaped their cancer trajectory. Conclusions While typical "survivorship" issues exist for many women with endometrial cancer (eg, physical, emotional, sexual health changes), a proportion of women will not be focused on their cancer and can be encouraged to form lives and identities that are not situated within the "cancer survivorship" culture. Implications for Practice A network of support, sensitive to women's responses to having cancer, may benefit women's long-term adjustment. Regular standardized assessment of women's needs may facilitate appropriate support for those with concerns, whereas those without concerns could be reassured by health professionals that their experience is normal and shared by other people with cancer. This may encourage women to form lives that are personally meaningful.

Bactrocera papayae Drew & Hancock, Bactrocera philippinensis Drew & Hancock, Bactrocera carambolae Drew & Hancock, and Bactrocera invadens Drew, Tsuruta & White are four horticultural pest tephritid fruit fly species that are highly similar, morphologically and genetically, to the destructive pest, the Oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae). This similarity has rendered the discovery of reliable diagnostic characters problematic, which, in view of the economic importance of these taxa and the international trade implications, has resulted in ongoing difficulties for many areas of plant protection and food security. Consequently, a major international collaborative and integrated multidisciplinary research effort was initiated in 2009 to build upon existing literature with the specific aim of resolving biological species limits among B. papayae, B. philippinensis, B. carambolae, B. invadens and B. dorsalis to overcome constraints to pest management and international trade. Bactrocera philippinensis has recently been synonymized with B. papayae as a result of this initiative and this review corroborates that finding; however, the other names remain in use. While consistent characters have been found to reliably distinguish B. carambolae from B. dorsalis, B. invadens and B. papayae, no such characters have been found to differentiate the latter three putative species. We conclude that B. carambolae is a valid species and that the remaining taxa, B. dorsalis, B. invadens and B. papayae, represent the same species. Thus, we consider B. dorsalis (Hendel) as the senior synonym of B. papayae Drew and Hancock syn.n. and B. invadens Drew, Tsuruta & White syn.n. A redescription of B. dorsalis is provided. Given the agricultural importance of B. dorsalis, this taxonomic decision will have significant global plant biosecurity implications, affecting pest management, quarantine, international trade, postharvest treatment and basic research. Throughout the paper, we emphasize the value of independent and multidisciplinary tools in delimiting species, particularly in complicated cases involving morphologically cryptic taxa.

In Australia, children with additional needs are now primarily educated in mainstream regular classes and schools. While discussion has focused on teacher attitudes, teacher preparation and professional development to support the academic progress of children with additional needs, there is limited research examining the educational contexts and services provided to such children in Australian schools. This descriptive paper examines the educational contexts of 563 Australian children with additional needs, in reference to 3600 of their typically developing peers. Data in relation to educational setting, retention, prevalence of additional needs, access to specialist services, learning support, and individual programming are reported.

Hydrogeophysics is a growing discipline that holds significant promise to help elucidate details of dynamic processes in the near surface, built on the ability of geophysical methods to measure properties from which hydrological and geochemical variables can be derived. For example, bulk electrical conductivity is governed by, amongst others, interstitial water content, fluid salinity, and temperature, and can be measured using a range of geophysical methods. In many cases, electrical resistivity tomography (ERT) is well suited to characterize these properties in multiple dimensions and to monitor dynamic processes, such as water infiltration and solute transport. In recent years, ERT has been used increasingly for ecosystem research in a wide range of settings; in particular to characterize vegetation-driven changes in root-zone and near-surface water dynamics. This increased popularity is due to operational factors (e.g., improved equipment, low site impact), data considerations (e.g., excellent repeatability), and the fact that ERT operates at scales significantly larger than traditional point sensors. Current limitations to a more widespread use of the approach include the high equipment costs, and the need for site-specific petrophysical relationships between properties of interest. In this presentation we will discuss recent equipment advances and theoretical and methodological aspects involved in the accurate estimation of soil moisture from ERT results. Examples will be presented from two studies in a temperate climate (Michigan, USA) and one from a humid tropical location (Tapajos, Brazil).

BACKGROUND Measuring disease and injury burden in populations requires a composite metric that captures both premature mortality and the prevalence and severity of ill-health. The 1990 Global Burden of Disease study proposed disability-adjusted life years (DALYs) to measure disease burden. No comprehensive update of disease burden worldwide incorporating a systematic reassessment of disease and injury-specific epidemiology has been done since the 1990 study. We aimed to calculate disease burden worldwide and for 21 regions for 1990, 2005, and 2010 with methods to enable meaningful comparisons over time. METHODS We calculated DALYs as the sum of years of life lost (YLLs) and years lived with disability (YLDs). DALYs were calculated for 291 causes, 20 age groups, both sexes, and for 187 countries, and aggregated to regional and global estimates of disease burden for three points in time with strictly comparable definitions and methods. YLLs were calculated from age-sex-country-time-specific estimates of mortality by cause, with death by standardised lost life expectancy at each age. YLDs were calculated as prevalence of 1160 disabling sequelae, by age, sex, and cause, and weighted by new disability weights for each health state. Neither YLLs nor YLDs were age-weighted or discounted. Uncertainty around cause-specific DALYs was calculated incorporating uncertainty in levels of all-cause mortality, cause-specific mortality, prevalence, and disability weights. FINDINGS Global DALYs remained stable from 1990 (2·503 billion) to 2010 (2·490 billion). Crude DALYs per 1000 decreased by 23% (472 per 1000 to 361 per 1000). An important shift has occurred in DALY composition with the contribution of deaths and disability among children (younger than 5 years of age) declining from 41% of global DALYs in 1990 to 25% in 2010. YLLs typically account for about half of disease burden in more developed regions (high-income Asia Pacific, western Europe, high-income North America, and Australasia), rising to over 80% of DALYs in sub-Saharan Africa. In 1990, 47% of DALYs worldwide were from communicable, maternal, neonatal, and nutritional disorders, 43% from non-communicable diseases, and 10% from injuries. By 2010, this had shifted to 35%, 54%, and 11%, respectively. Ischaemic heart disease was the leading cause of DALYs worldwide in 2010 (up from fourth rank in 1990, increasing by 29%), followed by lower respiratory infections (top rank in 1990; 44% decline in DALYs), stroke (fifth in 1990; 19% increase), diarrhoeal diseases (second in 1990; 51% decrease), and HIV/AIDS (33rd in 1990; 351% increase). Major depressive disorder increased from 15th to 11th rank (37% increase) and road injury from 12th to 10th rank (34% increase). Substantial heterogeneity exists in rankings of leading causes of disease burden among regions. INTERPRETATION Global disease burden has continued to shift away from communicable to non-communicable diseases and from premature death to years lived with disability. In sub-Saharan Africa, however, many communicable, maternal, neonatal, and nutritional disorders remain the dominant causes of disease burden. The rising burden from mental and behavioural disorders, musculoskeletal disorders, and diabetes will impose new challenges on health systems. Regional heterogeneity highlights the importance of understanding local burden of disease and setting goals and targets for the post-2015 agenda taking such patterns into account. Because of improved definitions, methods, and data, these results for 1990 and 2010 supersede all previously published Global Burden of Disease results.

This chapter takes as a working premise that digital culture is embedded in the every-day life experiences of most children living in post-industrial societies, both in home and, increasingly, in educational contexts. We outline how our research project investigated strategies for developing learning in the arts for young children by using the iPad as a creative device, rather than one on which they consume content in the form of games, on demand television and streaming video. We ask critical questions around creative ecologies and creative production; these grow from our observations on how young children and their families engaged with iPads through activities such as combining painting with digital photography. Analysis of work samples produced by children during the project enables interrogation of the ways in which young children can participate in arts practices and learning when digital media production is available. The chapter is structured around three themes of practice for iPad-based arts and creative education in preschool settings.

In this chapter we consider how the iPad and selected applications such as Draw and Tell (Duck Duck Moose, 2013), Popplet (Notion Inc., 2013) and Puppet Pals (Polished Play LLC, 2013) can assist children in collaborative storying, retelling and sequencing story moments that can assist young children in their acquisition of oracy and their understanding of the world, both real and imagined, and their personal relationships. The data gathered from the project will also analysed through the lense of “critical and creative thinking” (ACARA, 2013, p.20-21) skills articulated as one of the general capabilities required in all subject areas of the Australian national curriculum, but which has particular application to The Arts subject areas. In this chapter, we consider artefacts created by preschool children using iPads and selected apps and interviews conducted with preschool children and their caregivers during our research project. We then offer examples of practice to assist preschool teachers in supporting children in their storymaking using the iPad and discuss approaches for engagement that twins the live and mediatised representation of a story.

Early years education encompasses early childhood education and care (ECEC) and the early years of school across the age range birth to eight years. The introduction of two national curriculum documents for early years education – the Early Years Learning Framework (Department of Education, Employment and Workplace Relations DEEWR, 2009) for ECEC programs and the Australian Curriculum (Australian Curriculum, Assessment and Reporting Authority ACARA, 2011a) – indicates a trend towards national coherence, yet highlights a gap between notions of inclusion in the ECEC and school sectors of early years education. These gaps have the potential to impact negatively on school transition experiences through reductions in continuity of pedagogy and partnerships with families. Australian definitions of inclusion have moved beyond integration (i.e., mainstream classroom placement with support services and accommodations to address disability or lack of English), to encompass curricular and pedagogic differentiation catering for the participation rights and sense of belonging of children with a diverse range of abilities and backgrounds. This paper considers improved curriculum alignment and pedagogic continuity through enactment of elements relevant to inclusion.
