Perinatal mortality among term births: Informing decisions about singleton early term births in Western Australia.

To minimise the risk of perinatal mortality, clinicians and expectant mothers must understand the risks and benefits associated with continuing the pregnancy. Report the gestation-specific risk of perinatal mortality at term. Population-based cohort study using linked health data to identify all singleton births at gestations 37-41 weeks, in Western Australia (WA) from 2009 to 2019. Lifetable analysis was used to combine the risk of each type of perinatal mortality and calculate the cumulative risk of perinatal mortality, termed the perinatal risk index (PRI). Rates of antepartum and intrapartum stillbirth and neonatal death, as well as the PRI, were examined for each gestational week at term by non-Aboriginal and Aboriginal ethnicity. For non-Aboriginal women, rates were also examined by time-period (pre- vs. post-WA Preterm Birth Prevention Initiative (the Initiative) rollout), primiparity, and obstetric risk. There were 332,084 singleton term births, including 60 perinatal deaths to Aboriginal mothers (3.2 deaths per 1000 births to Aboriginal mothers) and 399 perinatal deaths to non-Aboriginal mothers (1.3 deaths per 1000 births to non-Aboriginal mothers). For non-Aboriginal women, the PRI was at its lowest (PRI 0.80, 95% CI 0.61, 1.00) at 39 weeks gestation. For Aboriginal women, it was at its lowest at 38 weeks (PRI 2.43, 95% CI 0.48, 4.39) with similar risk at 39 weeks (PRI 2.68, 95% CI 1.22, 4.14). The PRI increased steadily after 39 weeks gestation. The risk of perinatal mortality was higher among Aboriginal women. The gestation-specific perinatal mortality rates were similar by the time-period, primiparity and obstetric risk. The gestational ages at term associated with the lowest risk of perinatal mortality reinforce that the recommendation not to deliver before 39 weeks without medical indication is applicable to both Aboriginal and non-Aboriginal women giving birth in WA. There was no increase in the perinatal mortality rate associated with the introduction of the Initiative.

Trimodal skin health programme for childhood impetigo control in remote Western Australia (SToP): a cluster randomised, stepped-wedge trial.

Skin infections affect physical health and, through stigma, social-emotional health. When untreated, they can cause life-threatening conditions. We aimed to assess the effect of a holistic, co-designed, region-wide skin control programme on the prevalence of impetigo. The SToP (See, Treat, and Prevent Skin Sores and Scabies) trial is a pragmatic, open-cohort, stepped-wedge cluster randomised trial involving participants aged 0-18 years in nine remote communities of the Kimberley, Western Australia. The trial involves programmatic interventions in three domains: See (skin checks and skin infection recognition training), Treat (skin infection treatment training, sulfamethoxazole-trimethoprim for impetigo, and ivermectin for scabies), and Prevent (co-designed health promotion and environmental health). Four clusters, defined as pragmatic aggregations of communities, were randomised in two steps to progressively receive the activities during ten visits. The primary outcome was the proportion of school-aged children (aged 5-9 years) with impetigo. We adopted an intention-to-treat analysis and compared the intervention with the control (usual care before the start of intervention) states to derive a time and cluster averaged effect using Bayesian modelling. This study is registered with Australian New Zealand Clinical Trials Registry, ACTRN12618000520235. Between Sept 19, 2018, and Nov 22, 2022, 915 children were consented and 777 (85%) had skin checks performed on at least one of ten possible visits between May 5, 2019, and Nov 22, 2022. Of the participants, 448 (58%) of 777 were aged 5-9 years at one or more of the visit timepoints and were eligible for primary outcome assessment. A decline in impetigo occurred across all clusters, with the greatest decline during the observational period of baseline skin checks before commencement of the interventional trial activities activities. The mean (95% credible interval) for the conditional posterior odds ratio for observing impetigo in the intervention compared with the control period was 1·13 (0·71-1·70). The probability that the intervention reduced the odds of observing impetigo was 0·33. A decreased prevalence of impetigo during the observational period before the commencement of trial activities was sustained across the trial, attributable to the trimodal skin health initiative. Although the prevalence of impetigo reduced, there is no direct evidence to attribute this to the individual effects of the trial activities. The wholistic approach inclusive of skin checks collectively contributed to the sustained reduction in impetigo.

Incidence and outcomes for children with idiopathic inflammatory myopathy in Western Australia-a long-term population-based study.

To determine the incidence and health outcomes for juvenile idiopathic inflammatory myopathy (JIIM) in a long-term whole-population study. We included patients under 18 years hospitalized in Western Australia (WA) from 1985 and 2015 with incident JIIM as defined by pertinent diagnostic codes for dermatomyositis (JDM) polymyositis (JPM), other JIIM and overlap myositis (JOM). We compared clinical outcomes and modified Charlson comorbidity scores with age and gender matched (2:1 ratio) patients with new onset juvenile idiopathic arthritis (JIA). Trends over time for annual incidence rate per million child-population (AIR) were analyzed by least square regression and survival by Kaplan-Meier curves. We included 40 patients with JIIM (63% female, median age 8.5 years) for an average AIR of 2.52 per million (CI 1.09-5.57). AIR was stable over time leading to a point prevalence of 52.61 (CI 40.57-67.06) in 2015. Most patients (80%) were classified as JDM with an AIR for JDM of 2.02 (CI 1.09-5.58) and AIR for the combined other JIIM at 0.51 (CI 0.24-1.15). There was female preponderance (62.5%) in both JIIM groups, but no evidence of seasonality. Over a median follow-up of 13 years, one- and ten-year survival was 94.1%. Compared to JIA patients, readmission (80.4 vs. 63.7, p = .02) and infection rates (15.2 vs. 9.6, p < .01) per 100 person-years were higher for JIIM, with similar frequency of interstitial lung disease, fractures, and thrombotic events. At last observation, nearly all patients in both JIIM cohorts (97.5 vs. 92.5%) had accrued some form of comorbidity. The overall incidence of JIIM leading to hospitalization in WA was stable over 30 years. JIIM prognosis remains suboptimal due to early mortality and accrual of long-term comorbidity.

Epidemiology of antimicrobial resistance in commensal E. coli from healthy dairy cattle on a Mediterranean pasture-based system of Australia: A cross-sectional study

This study aimed to determine the prevalence of antimicrobial resistance (AMR) in commensal E. coli from healthy lactating cows and calves in the Mediterranean pasture-based feeding dairy system of Western Australia (WA). Fecal samples were collected from healthy adult lactating cows and healthy calves from dairy farms in WA. Presumptive commensal E. coli was isolated from these samples and confirmed using matrix-assisted laser-desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). Broth microdilution was used to assess the prevalence and the phenotypic AMR profiles of the E. coli isolates to 8 antimicrobial agents of dairy industry and human importance. The minimum inhibitory concentration (MIC) for each isolate was interpreted using the Epidemiologic Cutoff (ECOFF) and Clinical and Laboratory Standards Institute (CLSI) breakpoints. Genomic characterization provided multi-locus sequence types and AMR genes for a selection of isolates categorised as non-wild type (NWT) by ECOFF values for the combination of ampicillin, trimethoprim-sulfamethoxazole, and tetracycline. From a total of 1,117 fecal samples (633 adult, 484 calf) collected across 26 randomly selected farms, 891 commensal E. coli isolates were recovered (541 adult, 350 calf). Commensal E. coli classified as NWT was highest for ampicillin for both adult (68.8%; 95% CI = 64.7 - 72.7) and calf feces (67.1%; 95% CI = 62.0 - 72.0). A large proportion of tetracycline NWT and trimethoprim-sulfamethoxazole NWT organisms were also identified from calf feces, being 44.0% (95% CI = 38.7 - 49.4) and 24.6% (95% CI = 20.2 - 29.4) respectively. Clinical resistance prevalence was low, being higher for calves than for adult feces (ampicillin (adult: 7.8% (95% CI = 5.7 - 10.3); calf: 30.0% (95% CI = 25.2 - 35.1), tetracycline (adult: 6.3% (95% CI = 4.4 - 8.7); calf: 40.3% (95% CI = 35.1 - 45.6), and trimethoprim-sulfamethoxazole (adult: 2.6% (95% CI = 1.4 - 4.3); calf: 22.0% (95% CI = 17.7 - 26.7)). Commensal E. coli originating from calf feces was significantly higher in NWT prevalence compared with adult feces for ciprofloxacin (P = 0.023), gentamicin (P = 0.02), tetracycline (P < 0.001), and trimethoprim-sulfamethoxazole (P < 0.001). The overall number of antimicrobials an isolate was classified as NWT toward varied among farms and was significantly higher for isolates originating from calf than adult feces (P < 0.001). The strain type and sampling source of the commensal E. coli investigated were both associated with the commonality of the resultant resistance genome. Clinical resistance and NWT classification were highest for ampicillin, tetracycline, and trimethoprim-sulfamethoxazole, all antimicrobials commonly used in the treatment of dairy cattle in Australia. Though highly variable across farms, commensal E. coli isolated from healthy dairy calf feces had significantly higher NWT and multidrug resistance (MDR) prevalence compared with feces from healthy adult lactating dairy cows. The resistant genome identified in MDR isolates, though not always consistent with the phenotype, included QnrS1 and genes encoding AmpC β-lactamase and aminoglycoside phosphotransferase.

Relationship Between Renin, Aldosterone, Aldosterone-to-Renin Ratio and Arterial Stiffness and Left Ventricular Mass Index in Young Adults.

Primary aldosteronism, characterized by renin-independent aldosterone production, is associated with adverse cardiovascular remodeling and outcomes. Elevated cardiovascular risk is observed even in subclinical forms of primary aldosteronism according to studies conducted primarily in middle-aged and elderly populations. This study aimed to assess whether early changes in primary aldosteronism biomarkers during young adulthood are associated with arterial stiffness and left ventricular mass index (LVMI) before the onset of overt disease. The Raine Study is a longitudinal, population-based cohort study in Western Australia that enrolled women during pregnancy. We analyzed the data from the offspring of these women at 17 (2006-2009) and 27 (2016-2018) years of age. Participants with elevated high-sensitivity C-reactive protein (>10 mg/L) and female participants who were on oral contraception were excluded. Pulse wave velocity and aortic augmentation index were measured by SphygmoCor Pulse Wave System at both ages, and aortic distensibility and LVMI were measured by cardiac magnetic resonance imaging at 27 years. Multivariable linear regression was used to examine the relationship between plasma renin, aldosterone, or aldosterone-to-renin ratio and arterial stiffness and LVMI. Mediation analysis was used to test the role of systolic blood pressure. This study included 859 participants at 17 (38.0% female) and 758 participants at 27 (33.2% female) years of age. Females had lower renin concentration at both 17 (20.7 mU/L versus 25.7 mU/L; P<0.001) and 27 (12.0 mU/L versus 15.4 mU/L; P<0.001) years of age; hence, the aldosterone-to-renin ratio was significantly higher at both 17 (18.2 versus 13.5; P<0.001) and 27 (21.0 versus 15.6; P<0.001) years of age in females compared with males. At 27 years of age, a significant association was detected between aldosterone and LVMI in males (β=0.009 [95% CI, 0.001-0.017]; P=0.027) and between aldosterone-to-renin ratio and LVMI in females (β=0.098 [95% CI, 0.001-0.196]; P=0.050) independently of systolic blood pressure and other confounders. No association was found between primary aldosteronism biomarkers and measures of arterial stiffness (pulse wave velocity, aortic augmentation index, and aortic distensibility) at either age. Aldosterone concentration and aldosterone-to-renin ratio were positively associated with the LVMI in young males and females, respectively, independently of systolic blood pressure. Long-term follow-up is required to determine whether the relationship persists over time, and clinical trials are needed to assess the cardiovascular benefits of early interventions to block aldosterone.

Park thermal comfort and cooling mechanisms in present and future climate scenarios

Extreme heat is Australia’s most perilous natural hazard, and increasing urban temperatures due to climate change are a growing concern. Consequently, there is growing interest in developing nature-based solutions (i.e., greenery and vegetated surfaces) to cool urban areas. Appropriately designed urban parks are anticipated to be crucial for maintaining thermal comfort as temperatures rise. The two main diurnal cooling mechanisms of urban parks are shade provision and vegetation transpiration. However, limited studies have examined the cooling performance of vegetation through transpiration, especially in the southern hemisphere. This study addresses this gap by examining the microclimatic conditions, cooling benefits, and thermal performance of a typical neighbourhood park in Perth, Western Australia, with a focus on the cooling performance of vegetation through shade and transpiration. Present and future microclimates were modelled and simulated for average and hottest summer days based on 25 years of local weather data and projections for 2090 under the Representative Concentration Pathway (RCP) 8.5 scenario. The findings reveal that trees provided diurnal cooling benefits for park users by lowering the Universal Thermal Comfort Index (UTCI) by up to 17°C, with this benefit persisting in projected 2090 conditions. This cooling benefit was predominantly achieved through shade provision, with marginal contributions from transpiration. Additionally, on hot days, as leaf temperature exceeded 30°C, increased stomatal resistance led to reduced transpiration. Therefore, more attention must be paid to transpiration cooling limits due to stomatal closure during hot hours to improve cooling performance in park design. Moreover, comparing different plant species’ behaviour and adaptability on hot days is crucial, especially in future climatic conditions.

The inter-rater reliability of emergency department and paramedic frailty screening in older patients following a fall

BackgroundScreening for frailty in the emergency setting may be useful in directing patients to appropriate management pathways. The main aim of this study was to assess the inter-rater reliability of the Clinical Frailty Scale between paramedics and emergency department staff (doctors and allied heath) for patients after a fall. Secondarily, to assess how these scores correlate with patient outcomes. MethodsA prospective study of older patients arriving by ambulance to a single hospital in Western Australia following a fall. The inter-rater reliability was assessed using a weighted Cohen’s κ. The relationship between Clinical Frailty Scale and secondary outcomes were assessed using chi-squared and Kruskal-Wallis tests. ResultsData from 94 patients were included, the mean age was 82 years and 64 % were female.The inter-rater reliability between paramedics and emergency department staff using the Clinical Frailty Scale was moderate (κ 0.48 (95 % CI 0.36–0.59)). ConclusionsThere is only moderate agreement between emergency department staff and paramedics when screening for frailty in patients who present after a fall. The findings indicate the need to improve reliability as a pre-requisite to the use of frailty screening in emergency settings.

Fostering physical activity motivation at substance use disorder treatment facilities: A qualitative study grounded in self-determination theory

Background and aimsStudies have found inconclusive results for the effects of physical activity (PA) interventions on substance use, mental health, and physiological health of people experiencing substance use disorders (SUDs). To improve PA interventions for individuals with SUDs, a deeper understanding of the underlying motivational processes is imperative. This study employs self-determination theory as a framework to explore factors impacting PA motivation in SUD treatment contexts. MethodsA qualitative research design utilising semi-structured interviews explored the experiences and perspectives of five people with lived or living experience of SUD treatment and five stakeholders within SUD treatment facilities across Western Australia. A reflexive thematic analysis was employed for the data analysis. ResultsFive themes were developed: (i) Belonging to a Community, describing the sense of community fostered by group PA (ii) Mind, Body, and Soul, outlining the impact of PA on mental and physical well-being and sense of self; (iii) Physical Activity and Recovery Integration, describing how structured PA supports individuals transitioning from SUD treatment to community environments, (iv) Goals and Rewards, illustrating how setting goals fosters a sense of accomplishment, and (v) Safe Space, describing the importance of creating safe environments for PA exploration. ConclusionInsights gained from this study could be used to design PA interventions that address individuals’ basic psychological needs and promote more autonomous motivation while fostering peer connections, PA knowledge, and independence. These implementations may lead to greater PA engagement and adherence.

The initial impact of a predator exclosure sanctuary on small vertebrates in semi‐arid Western Australia

AbstractPredator exclosure reserves have become pivotal to conserving some threatened Australian mammalian fauna. However, the impact of predator exclosure reserves on resident (non‐target) small vertebrates is less understood. Given the potential ecological consequences of fencing, and the contribution of small vertebrates to ecosystem processes, we investigated species' occupancy, and site colonization and extinction dynamics, inside and outside of a predator exclosure fenced area for nine small vertebrates (six reptile, three mammal). We conducted vertebrate surveying 4 years (2011–2014) pre‐ and 2 years (2015–2016) post‐fence construction at the Australian Wildlife Conservancy Mt Gibson Sanctuary, in the semi‐arid, critically endangered Wheatbelt Eucalypt Woodlands of Western Australia, to assess spatial and temporal trends in small mammal and reptile populations. Of nine species modelled, one reptile (Diplodactylus pulcher) decreased in occupancy inside of the fence following construction. We detected no negative impact of the predator exclosure fence on the remaining eight species. One native reptile species (Lerista kingi) and an introduced rodent (Mus musculus) increased occupancy inside (but not outside) the fenced area. Spatial and temporal occupancy inside and outside of the fenced area for all other modelled species was stable. Biotic (habitat) factors and stochastic interannual detectability were the most significant drivers of species' occupancy. Species‐specific habitat associations were partially determined by site‐based presence and absence probabilities. This suggests that the predator exclosure sanctuary either benefitted or had minimal impact on all but one modelled species. These results may be a useful reference for future fencing projects aimed at both conservation and land management.

Place attachment and lived values in Western Australian communities

Substantial research exists on attachments people have to places and the phenomena and objects they value. However, insights on how values vary between different locations and across demographics and how place attachment differs between rural and urban areas are more limited. These understandings are needed to design meaningful adaptation strategies for people and communities at risk from climate change. This study examines attachment to place and things people value in eight communities in Western Australia, using a survey with 403 participants. Results showed that residents across the rural communities shared similar values, but that the values of urban communities were differentiated socioeconomically. Contrary to our hypothesis, place attachment was not stronger among the rural compared to the urban sites. The findings point to the importance of incorporating place-based, lived values and needs, particularly from less affluent residents, into inclusive adaptation planning.

Using desiccation-resistant eggs to explore the ecology of giant ostracods (subfamily Mytilocypridinae) in Australian salt lakes

AbstractGiant ostracods in the subfamily Mytilocypridinae are an important component of the biota of Australian salt lakes, which are predominantly temporary, and often located in remote arid areas. Mytilocypridines produce desiccation-resistant eggs to persist in these habitats during unfavourable conditions. In this study, we used mytilocypridine eggs collected from sediments in salt lakes in Western Australia to analyse aspects of the ecology of these ostracods. We conducted two rehydration trials, where sediment was collected from dry lakes or the dry margins of lakes, rehydrated in a laboratory setting, and selected mytilocypridine species hatched and raised in cultures. The first trial found that the eggs of mytilocypridine species were unevenly distributed in a dry lake and could be hatched even after 27 months of dry storage with no discernible loss of viability. The second trial assessed the capacity of selected mytilocypridines to hatch and develop into adults under different salinity treatments. One species, Australocypris insularis, hatched and developed across a very wide salinity range (0–100 g/L). Egg/sediment samples provide a means for testing species’ tolerance to physical and chemical variables throughout their entire life cycle, as well as for surveying the mytilocypridines in remote lakes that rarely hold water.

Child Protection Staff Perspectives of the SOFT Program: Touch, Textures, Weights, and Pressures

ABSTRACT Aboriginal children are overrepresented in Australia’s child protection system, and limited tools are available to assist with connecting these children to their culture. The Stitching Our Future Together (SOFT) Program, developed in consultation with Aboriginal and non-Aboriginal peoples, services, and other specialists, is used within the Department of Communities’ Child Protection and Family Support (CPFS) Division in Western Australia to address big emotions and safe behaviours with Aboriginal children in care. This study used phenomenology and social constructivism to explore CPFS staff’s perspectives and experiences of the SOFT Program. Seven semistructured in-depth interviews took place with CPFS staff. Five themes were identified: the SOFT Program and its use, culturally responsive practice, facilitating relationships, communication, and recommendations and implementation challenges. Participants expressed that the SOFT Program fostered an understanding of, and communication about, pertinent issues such as family and domestic violence, drug and alcohol addiction, mental health, and child neglect and abuse. The findings show how staff described the program’s capacity to help them navigate complex situations, highlighting the need to incorporate more culturally centred and creative-based work into child protection practice. IMPLICATIONS The SOFT Program positively supports culturally responsive practice and facilitates relationships and communication for child protection workers and children in care. The integration of creative and legislated practices assists with personalising and enhancing the effectiveness of child protection work with children in care.

Semisynthetic Studies Establish a Role for Conjugate Halide Exchange in the Formation of Chlorinated Pyrroloiminoquinones and Related Alkaloids.

Two novel pyrroloiminoquinone alkaloids, 6-chlorodamirone A and 6-bromodamirone A, have been identified for the first time from the marine sponge Latrunculia sp. (order: Poecilosclerida: family Latrunculiidae), sourced from Western Australia. Alongside these new compounds, seven previously known metabolites were also isolated. Despite being obtained in submilligram quantities, the structures of these natural products were successfully elucidated using high-resolution mass spectrometry and nuclear magnetic resonance spectroscopy. To confirm the structures of these newly discovered alkaloids, a semisynthetic approach was employed starting from the more abundant metabolite, damirone A, additionally, single crystal X-ray crystallography was used to validate our structural proposals. The semisynthetic studies suggest that the chlorinated alkaloids are likely formed through a nonenzymatic conjugate halide substitution reaction rather than an enzymatic process. This reactivity parallels that observed in related metabolites, such as the caulibugulones B and C. Furthermore, a biomimetic cascade reaction was attempted to synthesize the spirodienone moiety characteristic of the discorhabdin alkaloids, inspired by the nucleophilic substitution observed in the tricyclic damirone A system. Albeit unsuccessful, these findings provide valuable insight into the reactivity of halogenated pyrroloiminoquinones under various conditions.

Factors informing funding of health services for Aboriginal and Torres Strait Islander children: perspectives of decision-makers.

Background The factors informing decisions to fund health services for Aboriginal and Torres Strait Islander children are unclear. This study's objective aimed to describe decision-makers' perspectives on factors informing decisions to fund health services for Aboriginal and Torres Strait Islander children. Methods We conducted semi-structured interviews with 13 participants experienced in making funding decisions at organisational, state, territory and national levels. Decision-makers were from New South Wales, Northern Territory, Queensland, Victoria and Western Australia. Transcripts were analysed thematically following the principles of grounded theory. Results We identified five themes, each with subthemes. First, prioritising engagement for authentic partnerships (opportunities to build relationships and mutual understanding, co-design and co-evaluation for implementation). Second, valuing participant experiences to secure receptiveness (cultivating culturally safe environments to facilitate acceptability, empowering for self-determination and sustainability, strengthening connectedness and collaboration for holistic care, restoring confidence and generational trust through long-term commitments). Third, comprehensive approaches to promote health and wellbeing (linking impacts to developmental milestones, maintaining access to health care, broadening conceptualisations of child health). Fourth, threats to optimal service delivery (fractured and outdated technology systems amplify data access difficulties, failure to 'truly listen' fuelling redundant policy, rigid funding models undermining innovation). Fifth, navigating political and ideological hurdles to advance community priorities (negotiating politicians' willingness to support community-driven objectives, pressure to satisfy economic and policy considerations, countering entrenched hesitancy to community-controlled governance). Conclusion Decision-makers viewed participation, engagement, trust, empowerment and community acceptance as important indicators of service performance. This study highlights factors that influence decisions to fund health services for Aboriginal and Torres Strait Islander children.

Data resource profile: the ORIGINS project databank: a collaborative data resource for investigating the developmental origins of health and disease

IntroductionThe ORIGINS Project ("ORIGINS") is a longitudinal, population-level birth cohort with data and biosample collections that aim to facilitate research to reduce non-communicable diseases (NCDs) and encourage 'a healthy start to life'. ORIGINS has gathered millions of datapoints and over 400,000 biosamples over 15 timepoints, antenatally through to five years of age, from mothers, non-birthing partners and the child, across four health and wellness domains: 'Growth and development', 'Medical, biological and genetic', 'Biopsychosocial and cognitive', 'Lifestyle, environment and nutrition'. MethodsMothers, non-birthing partners and their offspring were recruited antenatally (between 18 and 38 weeks' gestation) from the Joondalup and Wanneroo communities of Perth, Western Australia from 2017 to 2024. Data come from several sources, including routine hospital antenatal and birthing data, ORIGINS clinical appointments, and online self-completed surveys comprising several standardised measures. Data are merged using the Medical Record Number (MRN), the ORIGINS Unique Identifier and the ORIGINS Pregnancy Number, as well as additional demographic data (e.g. name and date of birth) when necessary. ResultsThe data are held on an integrated data platform that extracts, links, ingests, integrates and stores ORIGINS' data on an Amazon Web Services (AWS) cloud-based data warehouse. Data are linked, transformed for cleaning and coding, and catalogued, ready to provide to sub-projects (independent researchers that apply to use ORIGINS data) to prepare for their own analyses. ORIGINS maximises data quality by checking and replacing missing and erroneous data across the various data sources. ConclusionAs a wide array of data across several different domains and timepoints has been collected, the options for future research and utilisation of the data and biosamples are broad. As ORIGINS aims to extend into middle childhood, researchers can examine which antenatal and early childhood factors predict middle childhood outcomes. ORIGINS also aims to link to State and Commonwealth data sets (e.g. Medicare, the National Assessment Program -- Literacy and Numeracy, the Pharmaceutical Benefits Scheme) which will cater to a wide array of research questions.

Young student’s views of NAPLAN: impact on wellbeing through drawn responses

Standardized testing of academic knowledge is common in many developed countries. In Australia, the process implemented is the National Assessment Program for Literacy and Numeracy (NAPLAN). The stand-alone tests were introduced in 2008 for several educational and political reasons, and since that time, the results of this assessment have been used beyond their initial purpose and brought about an unintended consequence of making the tests high-stakes. The pressure of these assessments has the potential to impact student’s wellbeing, but little research has been done in this area and even less where the student’s perspectives are considered. This research examined the impact of NAPLAN testing on the wellbeing of 1,015 students in Years 3 and 5 across 23 school sites within metropolitan Perth in Western Australia through three iterations. This research gave students the opportunity to draw or write how they felt about NAPLAN as a participatory approach to hearing children’s voices in research. This paper reports on the two-stage analysis of the 917 drawn images provided. Stage 1 analysis by two researchers categorized the images as initially positive, negative, or mixed/neutral and identified the impact across the cohorts of students was not significantly negative with an average of 22.5% of the images coded as negative. Stage 2 involved detailed systematic content analysis examining the actors, locations, and emotions of the drawings, which indicated high levels of stress and anxiety for a small number of these students. It was evident that the tests can have a negative impact on the wellbeing of some students and this finding requires consideration by policymakers and curriculum teams engaged with writing, implementing, and assessing NAPLAN as well as those using the results for both intended and unintended purposes.

Suspended Particulate Organic Matter Supports Mesopredatory Fish Across a Tropical Seascape

Understanding the sources of primary production supporting marine food webs is important for conserving critical habitats. However, the importance of allochthonous versus autochthonous production is often unclear. We identify the sources of primary production supporting three species of predatory fish (Lutjanus carponotatus, Lutjanus fulviflamma, and Lethrinus punctulatus) in the Dampier Archipelago, Western Australia. The proportions of mangrove, seagrass, macroalgae, and suspended particulate organic matter (SPOM) assimilated by fish of different life-history stages and from different habitats were determined using stable isotopes and Bayesian mixing models. While contributions of sources varied among species and habitats, we found that SPOM was an important energetic resource for both adults and juveniles of all three fish species. Juvenile L. carponotatus and L. punctulatus inhabiting macroalgal habitats assimilated more seagrass- and macroalgae-derived material than fish from coral or mangrove habitats, while reliance on mangrove carbon was generally limited overall. Assimilation of macrophyte-derived material decreased throughout ontogeny for L. carponotatus, while L. fulviflamma relied on a combination of SPOM and seagrass into adulthood. The contribution of macroalgae and SPOM to the diets of juvenile L. punctulatus and L. carponotatus from macroalgal habitats varied spatially but was unrelated to seascape configuration, habitat quality, or hydrodynamic conditions. While mixing models suggested a modest degree of trophic connectivity, cross-habitat trophic subsidies provided by macrophytes play a minor role in supporting the studied fish of either life-history stage. Instead, microalgal production predominantly fuels the productivity of predatory fish in this turbid, macrotidal system.

New carnivorous sponges (Porifera: Cladorhizidae) from Western Australia, collected by a Remotely Operated Vehicle (ROV).

The last two decades have reinvigorated systematic research on predatory sponges, mainly fuelled by advances in technology that have facilitated collection in deep-water habitats. This research presents six new species of carnivorous sponges from the family Cladorhizidae Dendy, 1922 from the western continental margin of Australia. The new species are Abyssocladia johnhooperi nov. sp., Abyssocladia aurora nov. sp., Abyssocladia janusi nov. sp., Axoniderma challengeri nov. sp., Cladorhiza vanessaekins nov. sp. and Nullarbora ningalooa nov. sp.. This material was collected by ROV during expeditions FK200308 to the Ningaloo Canyons expedition off the mid-west coast near Ningaloo, and FK200126 to the Southwest Australian canyons expedition, in Western Australia. These and other expeditions by the Schmidt Ocean Institute in 2020-21 formed a campaign around Australia's deep sea and mesophotic environments, which has vastly increased our understanding of biodiversity in these habitats.

The transformational possibilities of liberal vocationalism: a case study of post-year 10 Outdoor Education in Western Australia

ABSTRACT This paper discusses the transformative potential that liberal vocationalism, aligned with contemporary visions of lifelong and lifewide learning, presents for outdoor learning across institutional and industry settings. Utilising Bernstein’s sociological theory, the paper explores this transformation through an illustrative case study of the relations, knowledges and identities of post-Year10 Outdoor Education in Western Australia (WA). The case study highlights how Outdoor Education in WA has been organised through distinct classificatory relations that exist between government, regulatory bodies and individual industry providers that serve to distinguish Outdoor Education from outdoor learning that is ongoing and able to be pursued by people of any age in many and varied learning contexts. These classificatory relations are shown to be reflected in established qualification and training structures, privileged knowledges and particular subject and learner identities. It is argued that consequently, current post-Year10 Outdoor Education provision has a generated a vision of outdoor learning and vocationalism that constrains learners’ access to and engagement with lifelong and lifewide experiences that can enhance their own and others’ lives. In response, three foci are presented that constitute a heuristic framework via which transformative possibilities can be progressed. The first focus calls for progressive relations between institutional education, industry and community stakeholders in the creative re-design of qualification structures and educational experiences. The second underlies the need for qualification and training structures to enable all learners equitable access to knowledges for lifelong and lifewide learning. The third argues for the construction of new therapeutic identities in Outdoor Education that enables learners to orientate towards an experience of outdoor learning that is autonomous and flexible in both theory and practice. The paper concludes by considering research and teaching directions that can facilitate the realisation of these possibilities.
