- Abstract
School belonging, sometimes referred to as school belonging or school connectedness, involves dimensions like positive affect towards school, relationships with teachers, and feeling socially valued. Previous research points to immediate benefits for students' mental health and wellbeing; however, evidence on the potential long-term benefits of school belonging for mental health--once young people leave the school setting--is limited. This study used data on 1568 adults from the Australian Temperament Project (ATP), a 16-wave longitudinal study which has tracked participants since infancy. The short form of the Australian Council for Educational Research (ACER) School Life Questionnaire was used to assess secondary school belonging at age 15-16 years whilst young adult mental health symptoms were evaluated using the Depression, Anxiety and Stress Scales (DASS-21) at 19-20, 23-24, and 27-28 years. Generalised Estimating Equation models were used to examine the link between secondary school belonging and mental health symptoms in young adulthood. Results showed that higher levels of all aspects of school belonging were associated with lower mental health symptoms across young adulthood ([beta] range - 0.05 to - 0.20). Associations were similar by gender. These findings underscore the importance of adolescent school belonging and in particular school status in reference to feeling socially valued, as a long-term protective factor that can mitigate against later depression, anxiety, and stress.

- Abstract
This article describes a program that was developed to introduce senior high school students in Melbourne, Australia to the technique of X-ray crystallography within the context of chemistry research. Students had an opportunity for original experimentation, performing reactions and attempting to grow crystals of reaction products in a school laboratory. The program was remarkably successful, based on student feedback and scientific outcomes. In most cases, the compounds generated by students had not been synthesized before and their structures were previously unknown. X-ray diffraction data were collected on these crystalline products, and the students participated in data analysis and structure determination. New crystal structures were submitted to the international Cambridge Structural Database, with appropriate recognition of the students involved. Two peer-reviewed reports have been accepted for publication in the research literature with the students listed as coauthors. The experiences of the authors in developing this program should be of particular interest to science educators designing outreach activities for high school students.

- Abstract
Whilst online learning has gained rapid momentum, the development of online technology and practices that support the delivery of online courses with a large research component has been slow. In 2017, the School of Psychological Sciences at Monash University, Australia, developed a potentially scalable and transferable online research portal. This is an all-in-one platform that is designed to facilitate and support online research and research supervision, for supervisors and students. The research portal has evolved to currently provide research and research supervision support to over 700 online psychology students at the university. This paper describes the development, implementation and impact of the research portal and presents data from a preliminary evaluation of its usability and user satisfaction. Both research students and supervisors from the fully online fourth-year Graduate Diploma of Psychology Advanced program at Monash University participated in a series of focus groups, individual usability testing sessions, and surveys, and reported favourably on the research portal's research supervisor and supervisee user satisfaction and usability. Qualitative and quantitative feedback provided useful information supporting research portal improvement and expansion possibilities, allowing an increasingly valuable contribution to online research supervision, research and research teaching.

- Abstract
Objective: The Wechsler Preschool and Primary Scale of Intelligence -- Fourth Edition Australian and New Zealand Standardised Edition (WPPSI-IV[superscript A&NZ]) is one of the most widely used intelligence assessments for children aged 2 years 6 months to 7 years 7 months. Given the impact of clinical and placement decisions that are supported by WPPSI-IV[superscript A&NZ] results, it is important to provide evidence of criterion-related validity. Criterion-related validity refers to the degree to which test scores are associated with an external criterion (e.g., pre-existing diagnosis or classification). Method: Two studies of children with intellectual giftedness (n = 19) and intellectual disability (n = 15) were conducted to determine if the constructs measured by the WPPSI-IVA&NZ perform as expected in criterion groups with known characteristics. Results: Independent sample t-tests revealed mean composite scores for intellectually gifted children were significantly higher than matched controls, with the exception of the Processing Speed Index and Cognitive Proficiency Index. Children with intellectual disability on average obtained significantly lower mean scores on all composites relative to matched controls. Conclusion: Results indicated that the WPPSI-IV[superscript A&NZ] can provide valid estimates of intellectual ability for children with intellectual giftedness and intellectual disability that align with their previous diagnosis or classification.

Objectives: This study examined the factorial invariance of the factor structure of the Wechsler Intelligence Scale for Children, Fifth Edition (WISC‐V) across the UK, US and Australia & New Zealand (A&NZ). The factorial equivalence of cognitive assessments should be demonstrated before assuming cross‐culture generalizability and interpretations of score comparisons. Methods: Data were obtained from the UK, US and A&NZ normative standardizations of the WISC‐V. The samples consisted of 415 UK, 2200 US and 528 A&NZ children, aged 6–16. Confirmatory factor analysis was applied separately in each sample to establish the baseline model. Next, tests of factorial invariance were undertaken using the recommended hierarchical approach, firstly across the UK and A&NZ samples and then across the UK and US samples. Results: The five‐factor first‐order scoring model was found to be excellent fit across all three samples independently. Strict factorial invariance of the WISC‐V was demonstrated firstly across the UK and A&NZ and secondly the UK and US nationally representative standardization samples. Comparison of latent means found small but significant differences in female children across the UK and A&NZ samples. Conclusions: Consistent with previous research, these results demonstrate the generality of the WISC‐V factor structure across the UK, US and A&NZ. Furthermore, as the WISC‐V factor structure aligns with the Cattell–Horn–Carroll (CHC) model of cognitive abilities, the results add further support to the cross‐cultural generalizability of the CHC model. Small but significant differences in latent factor scores found across samples support the development and use of local normative data. [ABSTRACT FROM AUTHOR]

Background: Feelings of shame are linked to increased risk for depression. Little is known about protective factors that may buffer this effect, particularly in men. Using prospective data from a community sample of Australian men, we examine the extent to which shame is associated with depressive symptoms, and the protective role of psychological wellbeing, specifically environmental mastery and purpose in life. Methods: Participants (n = 448) were from the longitudinal Men and Parenting Pathways (MAPP) Study. Measures were the Event Related Shame and Guilt Scale for shame, the DASS-21 for depressive symptoms and Ryff's Scales of Psychological Well-Being for environmental mastery and purpose in life. Linear regressions were used to test associations between shame and depressive symptoms concurrently and 1-year later, and the moderating effects of mastery and purpose in life. Results: Shame was strongly associated with concurrent depressive symptoms (β
unadj =.76, p <.001; βadj =.63, p <.001). This effect was weaker in men with high compared to low environmental mastery (β =.46, p <.001; β+ 1SD −1 =.55, p <.001) and purpose in life (βSD =.48, p <.001; β+ 1SD −1 =.62, p <.001). Shame also predicted subsequent depressive symptoms after adjustment for prior depressive symptoms (βSD unadj =.59, p =.001; βadj =.34, p =.004), although environmental mastery or purpose in life did not moderate these associations. Conclusions: Our findings suggest that promoting a sense of psychological wellbeing in men may confer protective proximal effects in the context of shame, potentially attenuating depression severity. The current study aligns with calls for strength-based approaches to reducing mental health problems in men. [ABSTRACT FROM AUTHOR]- Published

Long-term declines in coastal water quality and sedimentation can affect the restoration success of ecosystems such as seagrass and shellfish reefs. Resnagging coastal seascapes offers a potential alternative restoration method that is not reliant on abiotic conditions and which may enhance degraded landscapes for fish and fisheries. While common in freshwater ecosystems, such interventions are unusual for coastal seascapes despite log snags supporting significant benefits for coastal fish. In this study, we identify the spatial (e.g. seascape connectivity), habitat condition (e.g. log snag complexity and food availability) and water quality variables that best explain variation in fish assemblages on log snags to help prioritise the placement and design of resnagging efforts in estuaries. We surveyed fish assemblages on log snags using underwater videography at 363 sites across 13 estuaries in southeast Queensland, Australia, over 3 years. Sites less than 10,000 m from the estuary mouth, more than 2500 m from urban structures and located in water depths of < 3 m harboured more diverse fish assemblages. Sites less than 10,000 m from the estuary mouth with lower (< 25%) algae cover harboured greater total fish abundance and harvested fish abundance. Similar trends were found for the abundance of individuals from key functional groups, although these trends were mediated by other seascape contexts (e.g. the area of natural habitat) and water quality variables (e.g. chlorophyll-a concentration and dissolved oxygen saturation). Our results indicate that log snag placement in estuaries for benefits to fish and fisheries can be maximised if sites are planned strategically. [ABSTRACT FROM AUTHOR]

Klopper, Christopher J. and Power, Bianca M.
- Abstract
Universities in many countries are struggling to adapt to the competing forces of globalisation, new managerialism, entrepreneurialism and new technologies and quality agenda demands. Diminishing resources caused by restricted funding and an aging and diminishing academic workforce pose barriers. One solution to staffing shortages is the casualisation of academic teachers increasing causal or sessional teaching staff who take on significantly increased teaching responsibilities. This article explores the casualisation of university academics and reports on preliminary findings of a small scale sessional teacher development program that used data from a questionnaire on demographics of a small group of 22 sessional teaching staff employed at an Australian university. Results indicated that sessional staff believed they were effective university teachers yet their ongoing development was hampered by heavy teaching workloads, other employment and lack of time. The article concludes that universities, to provide quality outcomes for students, must address these factors.

Introduction: Pressure injuries are a preventable yet highly prevalent health concern. Wheelchair cushion prescription can have significant implications for wheelchair users' risk of pressure injury development, which can impact functional abilities and quality of life. The efficacy of a wheelchair cushion to redistribute pressure has been well‐researched, but the efficacy to manage the microclimate is less clear, particularly in warm‐hot environments. The aim of this study was to systematically review studies examining the effect of wheelchair cushions on temperature, moisture and thermal perception to determine which cushions are superior to improve these responses. Method: A systematic review with meta‐analyses of randomised cross‐over and randomised control trials of wheelchair cushion interventions on measures of temperature, moisture, and thermal perception was conducted. Results: Eight studies were identified that met the eligibility criteria and six meta‐analyses were conducted. Pooled analyses identified a significantly lower temperature on foam‐gel cushions compared to air cushions (MD = 0.80, 95% CI: 0.31, 1.29; p = 0.002) and a significantly lower temperature on foam‐gel cushions compared to foam cushions (SMD = 0.76, 95%CI; 0.45, 1.06; p < 0.00001). Pooled analyses also demonstrated significantly lower relative humidity (i.e., moisture) on foam cushions compared to foam‐gel cushions (p = 0.02). Differences in thermal perception were inconclusive due to limited data found. Conclusion: It is clear that not one cushion is ideal in managing all aspects of microclimate, as foam‐gel cushions were the superior cushion to manage temperature and foam cushions were the superior cushion to manage moisture. This article provides occupational therapists and other health professionals with evidence‐based information to assist with wheelchair cushion prescription that minimises the temperature and moisture accumulation, and associated risk of pressure injury for wheelchair users.

Estuaries are crucial feeding, nursery and resting sites for fish but can also be subject to the impacts of severe flooding. The environmental features of estuaries can mediate how they respond to these impacts. For example, the size, configuration, and context of estuarine habitats across seascapes affects the value of patches for fish, and so fish assemblages at sites with a greater habitat extent or closer to the mouth of an estuary may rebound more quickly from flooding. We investigated how a once in 100-year flood event affected fish assemblages at approximately 600 sites across 13 estuaries and six estuarine habitats (bare sediments, log snags, mangrove forests, rocky structures, saltmarsh and seagrass meadows) in southeast Queensland, Australia, and determined whether flood impacts were mediated by the position of sites within the broader estuarine seascape. Sites were surveyed annually in 2020/2021 (pre-flood) and 2022 (6 months post-flood) using underwater videography. Flooding modified the structure of the fish community and reduced the abundance of fish targeted by local fisheries in all six habitats. Crucially, flood effects on fish were greater at sites near more expansive urbanisation in some ecosystems, but lower at sites nearer to the estuary mouth. Maximising the extent of natural habitats across estuaries can mediate the effects of floods and should be priorities for restoration and management plans seeking to maintain biodiversity and fisheries productivity in the face of increasing climate-related disturbances.

Ashton, Graham R. and Klopper, Christopher J.
- Abstract
There appear to be considerable differences in the outcomes of group string teaching programs in Queensland. Some teachers appear to be able to generate, manage, and administrate highly efficacious programs; others seem to experience difficulty transferring the knowledge and skills required for students to become successful string players. As a case study with multiple participants, this investigation set out to document the reflections of mid-career group string teachers, observe the outcomes of their programs and teaching methods, and establish a preliminary collective profile of skills, knowledge, and attributes. Key findings include a high degree of overlap in the participant profiles, and the potential for further research into undergraduate training and post-tertiary supervision of group string teachers entering the workforce. Implications of the study include the need to appraise current undergraduate programs preparing group instrumental teachers in Australia, and the necessity for developing strategies to mentor these graduates in their early teaching years.

15. 'They Didn't Even Let Me Say Goodbye': A Study of Imprisoned Primary Carer Fathers' Care Planning for Children at the Point of Arrest in Victoria, Australia

Bartlett, Tess S., Flynn, Catherine A., and Trotter, Christopher J.
- Abstract
In Victoria, data indicates that in 2013-2014 there were 74,992 adult male arrests, yet little formal attention has been paid to the parenting status of these men, despite knowledge of the impact of parental arrest and incarceration on children being well established. This article addresses a gap in the literature by providing new insights into the experiences of arrest of 34 primary carer fathers incarcerated in Victoria. It examines how incarcerated primary carer fathers experience planning processes for their children at the time of arrest and what factors facilitate or hinder the planning process. To do so, the article draws on data gathered for an Australian Research Council funded study conducted in Victoria and New South Wales between 2011 and 2015. Key issues include: the primary location of paternal arrest; the presence, or absence, of children at the location at which the arrest is made; police awareness of children; and subsequent discussions between police and fathers about suitable care. Findings indicate that half of all arrests took place in the family home. Children were present in 10 of these arrests and half were characterised by force, a large number of police, or weapons. Findings also indicate that in around one-half of all arrests, children were not physically present, despite fathers continuing to have responsibilities for these children. Despite 27 of the arrested men reporting that the police were aware (or made aware) of their children, almost all of these men (n = 26) were not asked about suitable care even when their children were physically present. Overall qualitative findings depict an absence of any discussion about children between police and fathers during the arrest process. The study highlights the demand for guidelines regarding child sensitive practice when a primary carer father is arrested.

Rasmussen, Christopher J.
- Abstract
The United States is in need of new strategies to address the historic inequity of access to its colleges and universities. Australia, with its system of deferred tuition and income-contingent repayment, can serve as a source of insight and guidance in addressing this problem and function as an interesting and helpful comparative case. In this study, a review of research on the efficacy of Australia's Higher Education Contribution Scheme is combined with an analysis of interviews conducted with 17 stakeholders from within and outside the Australian university system in which participants shared their views on the extent to which beliefs and values regarding the private and public benefits of higher education influence policy development and legislation and the merits of various alternative university finance and government models. Consideration is given to the applicability of the Australian model as a means of improving higher education access in the United States. (Contains 47 references.) (Author/SLD)

SHARKS , *ECOSYSTEMS , *SPECIES diversity , *TROPHIC cascades , *BIOTIC communities , *FISHING nets - Abstract
Human impacts lead to widespread changes in the abundance, diversity and traits of shark assemblages, altering the functioning of coastal ecosystems. The functional consequences of shark declines are often poorly understood due to the absence of empirical data describing long-term change. We use data from the Queensland Shark Control Program in eastern Australia, which has deployed mesh nets and baited hooks across 80 beaches using standardised methodologies since 1962. We illustrate consistent declines in shark functional richness quantified using both ecological (e.g., feeding, habitat and movement) and morphological (e.g., size, morphology) traits, and this corresponds with declining ecological functioning. We demonstrate a community shift from targeted apex sharks to a greater functional richness of non-target species. Declines in apex shark functional richness and corresponding changes in non-target species may lead to an anthropogenically induced trophic cascade. We suggest that repairing diminished shark populations is crucial for the stability of coastal ecosystems. This study illustrates consistent declines in shark functional richness which corresponds with declining ecological functioning and a community shift from targeted apex sharks to a greater functional richness of non-target species.

Background and Objectives Meaningful engagement is essential for aged care residents living with dementia. Our knowledge pertaining to caring presence for residents living with dementia is limited. This study aims to understand care workers' experiences of providing care to residents, the challenges they face in being present with residents and support that enable them to be more present and provide person-centered care. Research Design and Methods A mixed-methods approach using surveys and semi-structured interviews with care workers from three Australian residential aged care homes was adopted. Surveys were analyzed using descriptive statistics. Open-ended survey responses and interviews were analyzed using thematic analysis. Results Twenty-six care workers completed surveys and a subset (n = 8) participated in interviews. Survey participants were largely positive about their role and reported that they loved caring for and making a difference in the lives of residents. Three themes emerged from interviews: (a) trust, connection, and the complexities of maintaining engagement; (b) time as gift and challenge; (c) organizational culture, structure and resources, and enabling carer presence. Discussion and Implications Care workers in our study expressed their desire to be present with residents and stated that enablers such as meaningfully engaging with residents was one of the most enjoyable aspects of their work. Barriers such as staff shortages, competing demands of the role, and time-related impediments to being present were reported. Addressing challenges to being present with residents living with dementia is key to help avoiding poor care practices and resident outcomes. [ABSTRACT FROM AUTHOR]

Background: The number of older people experiencing homelessness in Australia is rising, yet there is a lack of specialised residential care for older people subject to homelessness with high care and palliative needs. To address this significant gap, a purpose-built care home was recently opened in Sydney, Australia. Methods: This qualitative study explores the experiences of both residents and staff who were living and working in the home over the first twelve months since its opening. Residents were interviewed at baseline (n = 32) and after six months (n = 22), while staff (n = 13) were interviewed after twelve months. Interviews were analysed using a reflexive thematic analysis approach informed by grounded theory. Results: Three main themes emerged: (1) Challenges in providing care for older people subject to homelessness with high care needs; (2) Defining a residential care service that supports older people subject to homelessness with high care needs, and (3) Perception of the impact of living and working in a purpose-built care home after six months (residents) and twelve months (staff) since its opening. A key finding was that of the complex interplay between resident dependency and behaviours, referral pathways and stakeholder engagement, government funding models and requirements, staff training and wellbeing, and the need to meet operational viability. Conclusion: This study provides novel insights into how the lives of older people subject to homelessness with high care needs are affected by living in a specifically designed care home, and on some of the challenges faced and solved by staff working in the care home. A significant gap in the healthcare system remains when it comes to the effective provision of high care for older people subject to homelessness. [ABSTRACT FROM AUTHOR]

Restoration projects are increasingly widespread and many promote habitat succession and the diversity and abundance of faunal communities. These positive effects on biodiversity and abundance may extend to enhancing the ecological functioning and resilience of previously degraded ecosystems, but this is rarely quantified. This study surveyed a 200‐ha restoring coastal wetland and three control wetlands in the Maroochy River, eastern Australia to compare the effects of wetland restoration on the consumption of carrion and the biodiversity, abundance, and functional diversity of functionally important fish and crustaceans. Carrion consumption by fish and crustaceans was measured every 6 months from spring 2017 until spring 2021 for nine events using a combination of baited cameras and scavenging assays. We found restoration improved rates of carrion consumption and the biodiversity, functional diversity, and abundance of scavenger species. Despite positive effects on the diversity of scavengers and carrion consumption, the abundance of two species, longfin eels (Anguilla reinhardtii) and mud crabs (Scylla serrata), was the most important predictors of carrion consumption rates. The spatial distribution of carrion consumption was concentrated in areas with high saltmarsh extent, moderate to high mangrove extent, and high salinity, which also resembled the distribution of both longfin eels and mud crabs. We show that restoration can promote the rates of key ecological functions but that increases to functions are likely to be characterized by low functional redundancy and greater complementarity. Therefore, maintaining or increasing the abundance of functionally important species should become a key objective in future restoration projects. [ABSTRACT FROM AUTHOR]

Background: Pleural procedures are essential for the investigation and management of pleural disease and can be associated with significant morbidity and mortality. There is a lack of pleural procedure complication data in the Australian and New Zealand region. Aims: To review pleural procedure practices at Wollongong Hospital with an emphasis on the assessment of complications, use of thoracic ultrasound (TUS), pathology results and comparison of findings with international data. Methods: Retrospective analysis of medical records was performed on pleural procedures identified through respiratory specialist trainee logbooks at Wollongong Hospital from January 2018 to December 2021. Comparison of complication rates was made to the British Thoracic Society 2011 a national pleural audit. Results: One hundred and twenty‐one pleural procedures were identified. There were 71 chest drains, 49 thoracocentesis and one indwelling pleural catheter (IPC) insertion. Ninety‐seven per cent of procedures were performed for pleural effusions and 3% for pneumothorax. This audit demonstrated a complication rate (excluding pain) of 16.9% for chest drains and 4.1% for thoracocentesis. This gave an overall complication event rate of 10.8% (excluding pain) for pleural procedures. There was no major bleeding, organ puncture, pleural space infection or death. Bedside TUS was used in 99% of procedures. Conclusion: Complication rates for pleural procedures performed by respiratory specialist trainees at Wollongong Hospital are comparable with international outcomes. This audit provides data for comparison on pleural procedure complication rates in Australia. Future studies are required to determine complication rates with IPCs. [ABSTRACT FROM AUTHOR]

Background: Here, we report new prevalence and temporal stability data for child attachment and parental caregiving behaviour, from infancy (1 year) to preschool (4 years). Methods: Attachment (SSP) and caregiving data (MBQS) were from observations of parents and their infants and preschoolers, who represent the third generation of participants within an Australian longitudinal cohort. Results: At 1 year (n = 314 dyads) and at 4 years (n = 368 dyads), proportions assessed secure were 59% and 71%, respectively. Proportions assessed avoidant were 15% and 11%; ambivalent 9% and 6%, and disorganised 17% and 12%, at 1 and 4 years. Continuity of attachment pattern was highest for the infant secure group. Of dyads initially classified disorganised in infancy, 36% remained so at the preschool assessment. Attachment and caregiving continuities across the infancy–preschool period were highest for the stable secure attachment group and lowest for the stable insecure attachment group. Loss of secure attachment to mother by age 4 years correlated with decreased maternal caregiving sensitivity, and acquisition of secure status by age 4 was associated with increased maternal sensitivity. We found no difference in caregiving sensitivity scores for mothers and fathers for female and male preschool children. Conclusions: The contemporary infant and preschool attachment proportions we report here closely mirror the patterns of those reported in prior decades, with an inclination towards secure base relationships. Our findings alert practitioners anew to the responsiveness of early attachment status to change in caregiving responsiveness and support ongoing investment in early identification of disorganised attachment.

Romantic and peer relationships both contribute to overall well-being; however, each demand time and emotional investment that may give rise to competition. Little is known about how men, in particular, balance these relationships. We explored the extent to which men's investments in peer relationships are associated with romantic relationship quality. We further examined differences between fathers and non-fathers. Data were from five annual waves of the Men and Parenting Pathways cohort study (N = 608). Participants were men in committed relationships (n = 526) aged 28-32 years at baseline (M = 29.91, SD = 1.3). In cross-sectional, linear regressions, estimated using Generalised Estimating Equations (GEE; to account for repeated waves), we investigated peer network investments, (1) time (hours) spent with peers, (2) close network size, and (3) extended network size, and their associations with romantic relationship quality, self-reported using the Dyadic Adjustment Scale. Inverted U-shaped associations were found for time spent with peers and close network size, whereby increases in investment were associated with improved relationship quality up to a "tipping point", following which declines in quality are observed. For extended social networks, the association was linear, such that larger networks were linked to higher romantic relationship quality; however, this association was only evident in fathers. Investing too little or too much in peer relationships may adversely impact the quality of men's relationships with romantic partners. Supporting men, and particularly fathers, to maintain appropriate investment in peer networks may have benefits for their romantic relationships. [ABSTRACT FROM AUTHOR]

A morphodynamic approach to coastal evolution involves recognition of internal thresholds, feedbacks and boundary conditions and should underpin coastal management. The Holocene evolution of the Bega River estuary and Tathra Beach coastal barrier was examined integrating existing sediment cores and radiocarbon dating, airborne terrestrial and marine Lidar and OSL dating. Sediment coring reveals the Bega River estuary began infilling with fluvial sand once sea levels stabilised at or near their present elevation. Radiocarbon dating suggests a prograding fluvial delta reached the coast approximately 4000–2250 years BP. Barrier deposition commenced ~3200 years ago coinciding with the arrival of fluvial sand at the coast. Shoreline progradation of the Tathra barrier occurred at 0.15 m/year from ~3200 years to present forming a sequence of ~17 foredune ridges which were each active for an average of ~190 years. In the past ~500 years, a sand spit has restricted the entrance of the Bega River estuary to the northern end of the embayment. The infill of the Bega River estuary over the Holocene represents an internal morphodynamic threshold or tipping point, which then enabled coastal barrier deposition as fluvial sand reached the coast. The coastal system approaches another threshold as the Tathra embayment infills, and sediment may be transported northward out of the embayment. At Tathra Beach, the positive sediment budget which resulted in barrier progradation is approximately 0.55 m3/m/year. This signal is masked on the yearly to decadal scale by fluctuations in beach volume an order of magnitude greater (5–20 m3/m/year depending on the timeframe examined). Thus longer-term datasets of beach change or reconstructions from the geological record are needed to underpin management decisions which will impact shorelines decades or centuries into the future.

Chronic insecurities that emerge from adverse experiences in early intimate partner relationships in adolescence and emerging adulthood can have profound impacts on mental health and well‐being. Less clear is the extent to which these experiences for parents impact subsequent relationships within and across generations. We examine the extent to which secure, dismissing, pre‐occupied, and fearful intimate partner relationships in adolescence and emerging adulthood, well before becoming a parent, are associated with next‐generation patterns of attachment between mothers and infant offspring. Data were drawn from a nested study of infant–mother attachment (n = 220) within the Australian Temperament Project Generation 3 Study (N = 1167, est. 1983). Intimate partner relationships in adolescence and young adulthood were assessed by self‐report at 23–24 years of age. Over a decade later, infant–mother attachment security was assessed at 12 months post‐partum. Young adult intimate partner relationships defined by high levels of fearful, pre‐occupied, and dismissing attachment styles were reported in 11%, 17%, and 38% of young mothers, respectively. Increases in fear of intimacy in relationships were associated with an increase in the odds, by around 50%, of infant–mother insecure attachments (vs secure; OR = 1.56, 95% CI = 1.07, 2.28) and disorganised attachments (vs organised; OR = 1.49, 95% CI = 1.00, 2.22). A mother's self‐reported history of fear of intimacy within young adult relationships predicts later insecure and disorganised mother–infant attachments. Guidance and greater support for young people navigating their earliest intimate relationships may not only prevent adverse relational experiences at the time but also on becoming a parent. Findings have relevance for family and infant mental health therapies. Translating these findings into supported conversations may help prevent infant–mother attachment difficulties, or later repair them, through validation of the lingering effects of early fear of intimacy and empowerment of parents to prevent next‐generation infant experiences of distrust.

Invasive species cause severe threats to biodiversity and the economy, but often across multi‐actor landscapes. Therefore, collaboration among multiple actors across landscapes is often essential for managing invasive species. Deciding whether to collaborate depends on available resources and potential benefits. As such, it is vital to identify how different factors can influence the outcomes of collaborations.We developed and tested a conceptual model that integrates potential process factors and performance measures for outcomes of collaborative invasive species management. We surveyed professionals engaged in invasive species management in Queensland, Australia. We first assessed their perception of the presence of process factors and perception of the performance measures of collaborative invasive species management projects using descriptive methods. Then we tested the associations between process factors and performance measures using structural equation modelling.While confirming that a good collaboration of stakeholders (e.g. communication and trust) is essential to enhance performances, our results suggest that the way collaborative projects are structured (e.g. ability to participate in decision‐making, having shared goals) also significantly influences the performance of the projects, especially in achieving goals. Furthermore, results suggest that achieving long‐term collaborations and outcomes is directly influenced by the extent to which stakeholders support or oppose the collaboration. As such, our study contributes to a significant research gap by establishing a connection between the collaboration process and its outcomes.We conclude that decision‐makers should give equal importance to both designing favourable collaborative project structures and fostering collaborations with stakeholders through different means to enhance the benefits of collaboration in invasive species management.

Background: Shoulder pain is common among the adult population, but it appears to reduce in prevalence around retirement age. Associations between shoulder pain and work-place exposures, physical activity, or mental health status are unclear and may change with age. This study aimed to determine the prevalence of self-reported shoulder pain in Australian adults across two generations and test the association with occupational factors, physical activity, and mental health. Methods: In this cross-sectional study we used data from a longitudinal Australian pregnancy cohort (the Raine Study). We analysed data from the children (Gen2) at the 22-year follow-up (N = 1128) and parents (Gen1) at the 26-year follow-up (N = 1098). Data were collected on self-reported shoulder pain, occupational factors (employment status and work description), physical activity, and mental health at the respective follow-ups. Prevalence rates were provided as percentages with 95% confidence intervals. Univariate analysis for group comparisons included chi squared for categorical comparisons. The association of predictor variables and shoulder pain was assessed using logistical regression. Results: In Gen1 31.4% of adults aged 40–80 reported the presence of shoulder pain in the last month, with no significant difference between females and males. Gen1 participants younger than 65 reported more shoulder pain (OR[95%CI] = 1.80 [1.04–3.09]). Gen2 females (14.7%) reported shoulder pain in either shoulder more frequently than males (7.7%) and bilateral shoulder pain (8.0%) more frequently than males (1.9%). Gen1 had increased odds of reporting shoulder pain if their work was "physical or heavy manual" compared to "sedentary" (OR [95% CI] = 1.659 [1.185–2.323]) and when categorised with depression (OR [95% CI] = 1.940 [1.386–2.715]) or anxiety (OR [95% CI] = 1.977 [1.368–2.857]). Gen2 participants with depression (OR [95% CI] = 2.356 [1.620–3.427]) or anxiety (OR [95% CI] = 2.003 [1.359–2.952]) reported more shoulder pain. Conclusion: Overall, shoulder pain was more prevalent in young females than males and was more prevalent in those under the age of 65. Cross-sectional associations were established between some occupational factors in older adults and depression in all adults, and shoulder pain. Highlights/clinical messages: In the younger generation females had significantly higher rates of shoulder pain and in particular were almost four times as likely to report bilateral shoulder pain. In the older generation, those over the ages of 65 were less likely to report shoulder pain. In the older generation, physical or heavy work is associated with higher rates of shoulder pain. In both generations depression and anxiety were associated with higher rates of shoulder pain. Physical activity was not associated with shoulder pain in either generation. [ABSTRACT FROM AUTHOR]

Heatwaves have been shown to increase the likelihood and intensity of extreme rainfall occurring immediately afterward, potentially leading to increased flood risk. However, the exact mechanisms connecting heatwaves to extreme rainfall remain poorly understood. In this study, we use weather type data sets for Australia and Europe to identify weather patterns, including fronts, cyclones, and thunderstorm conditions, associated with heatwave terminations and following extreme rainfall events. We further analyze, using reanalysis data, how atmospheric instability and moisture availability change before and after the heatwave termination depending on whether the heatwave is followed by extreme rainfall, as well as the location of the heatwave. We find that most heatwaves terminate during thunderstorm and/or frontal conditions. Additionally, atmospheric instability and moisture availability increase several days before the heatwave termination; but only if heatwaves are followed by extreme rainfall. We also find that atmospheric instability and moisture after a heatwave are significantly higher than expected from climatology for the same time of the year, and that highest values of instability and moisture are associated with highest post‐heatwave rainfall intensities. We conclude that the joint presence of high atmospheric instability, moisture, as well as frontal systems are likely to explain why rainfall is generally more extreme and likely after heatwaves, as well as why this compound hazard is mainly found in the non‐arid mid and high latitudes. An improved understanding of the drivers of these compound events will help assess potential changing impacts in the future. Plain Language Summary: Extreme rainfall which can lead to flash floods is more likely to occur if it is preceded by a heatwave. The exact reasons behind this connection, however, are not fully clear. In this study we investigate the mechanistic drivers connecting heatwaves to extreme rainfall in Europe and Australia by analyzing which types of weather (e.g., fronts, cyclones, thunderstorms) are present during the transition from heatwaves to extreme rainfall. We also analyze how atmospheric characteristics associated with extreme rainfall during thunderstorms change depending on if a heatwave is followed by extreme rainfall or not. We find that heatwaves are usually followed by extreme rainfall when there are thunderstorm conditions and/or when there is the presence of a front. Further, we find that high amounts of moisture are present if heatwaves are followed by extreme rainfall and that atmospheric conditions favorable for thunderstorms, including high amounts of moisture are generally increased after heatwaves. These findings help understand how heatwaves are connected to extreme rainfall and can help assess how the risk from these events might change in the future. Key Points: The transition from heatwaves to extreme rainfall is usually associated with fronts and/or thunderstorm conditionsAtmospheric instability and moisture are larger than during non‐heatwave conditions and increase over several days before the terminationAvailability of moisture is important for producing extreme rainfall after heatwaves and explains the spatial variability for this event [ABSTRACT FROM AUTHOR]

Early indicators of restoration success can inform adaptive management strategies and maintain community interest and financial investment. Coastal wetland restoration projects prioritize monitoring the succession of habitat forming communities. However, these communities often expand slowly. In contrast, fish and crustaceans can quickly occupy newly available habitats and therefore, may be early indicators of restoration success. Here, we compared the short‐term responses of fish and crustacean communities and landcover area to restoration actions at a restoring wetland and three reference wetlands in the Maroochy River in eastern Australia. Fish and crustacean communities and landcover area were surveyed every 6 months between Spring 2017 and Spring 2019 (n = 5), with two sampling events conducted before restoration actions commenced in May 2018 and three after. Fish and crustaceans were surveyed using baited underwater video stations and fyke nets. Landcover was remotely sensed using a combination of Worldview‐2 satellite imagery, object‐based image analysis, and random forest classification. Fish and crustaceans make viable indicators for early restoration success, as our findings show the composition, diversity, and abundance of species targeted in fisheries of these communities can resemble assemblages at reference sites within 1 year of restoration actions. The area of tidal inundation significantly increased overtime, but the recovery of mangroves and saltmarsh communities did not. These findings support the notion that coastal wetland restoration can promote immediate recruitment by fish and crustacean communities, thus making these taxa useful indicators for communicating early success of restoration projects.

BLUE economy ,STRUCTURAL failures ,HAZARDS ,MARICULTURE - Abstract
A multi-sectoral assessment of risks can support the management and investment decisions necessary for emerging blue economy industries to succeed. Traditional risk assessment methods will be challenged when applied to the complex socio-ecological systems that characterise offshore environments, and when data available to support management are lacking. Therefore, there is a need for assessments that account for multiple sectors. Here we describe the development of an efficient method for an integrated hazard analysis that is a precursor to full risk assessments. Our approach combines diverse disciplinary expertise, expert elicitation and multi-criteria analysis to rank hazards, so it encompasses all types of hazards including human-caused, natural and technological. We demonstrate our approach for two sectors that are predicted to grow rapidly in Australia: offshore aquaculture and marine renewable energy. Experts ranked Climate Change as the hazard with the highest overall concern, but hazards including Altered Ecosystem Function , Biosecurity , Cumulative Effects , Structural Failure and Social Licence were also highly ranked. We show here how outputs from this approach (multi-criteria scores and ranks) could be used to identify hazards that; i) could be safely retired, ii) should be progressed to more quantitative risk assessments or iii) require ongoing information collection. The approach can encompass all types of hazards, which enables it to holistically consider priorities. The expert-based multi-criteria approach outlined here represents a pragmatic way to solve some of the challenges of applying risk assessments to emerging industries by using a method that can be applied across multiple blue economy sectors. • We develop an integrated method to assess hazards to and from blue growth sectors. • We combine diverse expertise, expert elicitation and multi-criteria analysis. • Our approach provides a clear process for prioritizing hazards.

Objectives: This study was aimed at understanding the attitudes and positions of key Australian organisational and political stakeholders towards using psychedelic agents in medically supervised environments to treat mental health conditions. Specifically, this research was designed to identify some of the issues that might impede the clinical implementation of psychedelics. Methods: Semi-structured interviews were conducted with four Australian politicians and nine representatives of key stakeholder organisations between September 2022 and January 2023. Data analyses were completed using pattern-based inductive thematic analysis. Results: Participants were cautiously optimistic about using psychedelics to treat mental health conditions, with hesitancy emerging due to the perceived inadequacy of research into the efficacy and feasibility of these treatments. Politicians consistently mentioned that negative stigma prevented them and their peers from supporting the use of psychedelics in Australia. Effective, evidence-based, clear messaging that refutes misconceptions, uses persuasive messaging and provides clear information to inform implementation is needed to improve knowledge and challenge attitudes, biases and emotions that can influence the debate around psychedelics. Conclusions: Stakeholder representatives and politicians agree that insufficient evidence exists to support the widespread clinical implementation of psychedelics in Australia. Politicians also perceive the stigma associated with psychedelics might negatively influence progressive legislation. Additional research and a clear presentation of this research are needed before the clinical use of psychedelics can be supported. [ABSTRACT FROM AUTHOR]

Headwater streams are critical to the integrity of the stream network, yet they are being rapidly degraded, channelized, or lost through land-cover and land-use change, particularly in urbanizing areas. We refined the definition of a headwater stream, reviewed the headwater stream ecosystem literature using examples from southeastern Australia and globally, and identified 4 critical knowledge gaps that are hampering the management of these unique systems: 1) inadequate high-resolution mapping and, thus, low-accuracy estimates of headwater stream locations and extents within catchments; 2) insufficient characterization of headwater stream typologies across varying geological, topographical, climatic, and anthropogenic conditions; 3) incomplete quantification of headwater stream structure, function, and ecosystem services across varying scales; and 4) limited understanding of the effects of urbanization on headwater streams against a backdrop of climate change. We propose a series of research questions to address these gaps and, finally, hypothesize and discuss the most effective ways to protect headwater streams in urbanizing environments given our current state of understanding. Of particular importance are the need to 1) shift perceptions of these systems as dry, insignificant depressions in the landscape; 2) manage both the headwater stream catchment and the channel; and 3) prioritize protection of the natural flow regime.

Purpose: There is debate as to which environmental intervention produces the most benefit for team sport athletes, particularly comparing heat and altitude. This quasi-experimental study aimed to compare blood volume (BV) responses with heat and altitude training camps in Australian footballers. Methods: The BV of 7 professional Australian footballers (91.8 [10.5] kg, 191.8 [10.1] cm) was measured throughout 3 consecutive spring/summer preseasons. During each preseason, players participated in altitude (year 1 and year 2) and heat (year 3) environmental training camps. Year 1 and year 2 altitude camps were in November/December in the United States, whereas the year 3 heat camp was in February/March in Australia after a full exposure to summer heat. BV, red cell volume, and plasma volume (PV) were measured at least 3 times during each preseason. Results: Red cell volume increased substantially following altitude in both year 1 (d = 0.67) and year 2 (d = 1.03), before returning to baseline 4 weeks postaltitude. Immediately following altitude, concurrent decreases in PV were observed during year 1 (d = −0.40) and year 2 (d = −0.98). With spring/summer training in year 3, BV and PV were substantially higher in January than temporally matched postaltitude measurements during year 1 (BV: d = −0.93, PV: d = −1.07) and year 2 (BV: d = −1.99, PV: d = −2.25), with year 3 total BV, red cell volume, and PV not changing further despite the 6-day heat intervention. Conclusions: We found greater BV after training throughout spring/summer conditions, compared with interrupting spring/summer exposure to train at altitude in the cold, with no additional benefits observed from a heat camp following spring/summer training.

Athletes use postexercise hydrotherapy strategies to improve recovery and competition performance and to enhance adaptative responses to training. Using a randomized cross-over design, the acute effects of 3 postresistance exercise water immersion strategies on perceived recovery, neuromuscular performance, and hormone concentrations in junior international and subelite male volleyball athletes (n = 18) were investigated. After resistance exercise, subjects randomly completed either 15-minute passive control (CON), contrast water therapy (CWT), cold (CWI), or hot water immersion (HWI) interventions. A treatment effect occurred after HWI; reducing perceptions of fatigue (HWI > CWT: p = 0.05, g = 0.43); improved sleep quality, compared with CON (p < 0.001, g = 1.15), CWI (p = 0.017, g = 0.70), and CWT (p 5 0.018, g 5 0.51); as well as increasing testosterone concentration (HWI > CWT: p = 0.038, g = 0.24). There were trivial to small (p < 0.001-0.039, g = 0.02-0.34) improvements (treatment effect) in jump performance (i.e., squat jump and counter- movement jump) after all water immersion strategies, as compared with CON, with high variability in the individual responses. There were no significant differences (interaction effect, p > 0.05) observed between the water immersion intervention strategies and CON in performance (p = 0.153-0.99), hormone (p = 0.207-0.938), nor perceptual (p = 0.368-0.955) measures. To optimize recovery and performance responses, e.g., during an in-season competition phase, postresistance exercise HWI may assist with providing small-to-large improvements for up to 38 hours in perceived recovery (i.e., increased sleep quality and reduced fatigue) and increases in circulating testosterone concentration. Practitioners should consider individual athlete neuromuscular performance responses when prescribing postexercise hydrotherapy. These findings apply to athletes who aim to improve their recovery status, where postresistance exercise HWI optimizes sleep quality and next-day perceptions of fatigue. [ABSTRACT FROM AUTHOR]

Background and Aims: Alcohol is a major modifiable risk factor for female breast cancer, with breast cancer risk now associated with substantially lower consumption levels than those previously deemed safe. This study sought to measure risky drinking among women attending breast screening services in Australia according to new national alcohol guidelines and to compare daily, weekly and recent (past 12 months) consumption to Australian gender and age population norms. Design, Setting and Participants: This study was a retrospective analysis of cross‐sectional data from the Lifepool Project (collected October 2011–January 2016) in Victoria, Australia, comprising a convenience sample of women attending breast screening services aged 40+ years. Measurements: Typical and heavy alcohol consumption patterns over the previous 12 months (frequency, quantity), socio‐demographic (e.g. age, education) and health‐related (e.g. menopause status, breast cancer history) characteristics. Primary outcomes were the proportion of women drinking at a level exceeding new guidelines for weekly and daily alcohol consumption. Findings Of 49 240 women, mean age was 59.94 years (standard deviation = 7.14, range = 40–94 years). Most women had consumed alcohol during the past 12 months [41 628, 85.48%, 95% confidence interval (CI) = 85.16, 85.79]. One in five women (8464, 18.34%, 95% CI = 17.99, 18.69) were drinking at a level exceeding new national guidelines for weekly consumption (i.e. greater than 10 standard drinks per week), and one in six (7446, 15.60%, 95% CI = 15.28, 15.93) were exceeding new guidelines for consumption on a single day (i.e. greater than four standard drinks on any 1 day, more than once per month). The proportion of women in this sample drinking daily (4.21–11.19%), weekly (34.73–50.71%) and in the past 12 months (74.96–90.81%) was significantly greater among nearly all age groups (by decade), compared with Australian gender and age norms [drinking daily (3.4–9.1%), weekly (27.1–37.6%) and in the past 12 months (64.4–81.9%)]. Conclusions: There appears to be a high prevalence of risky alcohol consumption among a large convenience sample of breast screening service clients in Australia using new national alcohol guidelines introduced in December 2020.

Geological maps are powerful models for visualizing the complex distribution of rock types through space and time. However, the descriptive information that forms the basis for a preferred map interpretation is typically stored in geological map databases as unstructured text data that are difficult to use in practice. Herein we apply natural language processing (NLP) to geoscientific text data from Canada, the U.S., and Australia to address that knowledge gap. First, rock descriptions, geological ages, lithostratigraphic and lithodemic information, and other long-form text data are translated to numerical vectors, i.e., a word embedding, using a geoscience language model. Network analysis of word associations, nearest neighbors, and principal component analysis are then used to extract meaningful semantic relationships between rock types. We further demonstrate using simple Naive Bayes classifiers and the area under receiver operating characteristics plots (AUC) how word vectors can be used to: (1) predict the locations of "pegmatitic" (AUC = 0.962) and "alkalic" (AUC = 0.938) rocks; (2) predict mineral potential for Mississippi-Valley-type (AUC = 0.868) and clastic-dominated (AUC = 0.809) Zn-Pb deposits; and (3) search geoscientific text data for analogues of the giant Mount Isa clastic-dominated Zn-Pb deposit using the cosine similarities between word vectors. This form of semantic search is a promising NLP approach for assessing mineral potential with limited training data. Overall, the results highlight how geoscience language models and NLP can be used to extract new knowledge from unstructured text data and reduce the mineral exploration search space for critical raw materials.

Background: Obesity is a known risk factor for the development of hip osteoarthritis. The aim of this study was to investigate whether obesity is associated with the risk of undergoing total hip replacement (THR) in Australia. Methods: A cohort study was conducted comparing data from the Australian Bureau of Statistics and the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) from 2017 to 2018. Body mass index (BMI) data for patients undergoing primary total hip replacement and resurfacing for osteoarthritis were obtained from the AOANJRR. The distribution of THR patients by BMI category was compared to the general population, in age and sex sub‐groups. Results: During the study period, 32 495 primary THR were performed for osteoarthritis in Australia. Compared to the general population, there was a higher prevalence of Class I, II and III obesity in patients undergoing THR in both sexes aged 35–74 years. Class III obese females and males aged 55–64 years were 2.9 and 1.7 times more likely to undergo THR, respectively (P < 0.001). Class III obese females and males underwent THR on average 5.7 and 7.0 years younger than their normal weight counterparts, respectively. Conclusion: Obese Australians are at increased risk of undergoing THR, and at a younger age. [ABSTRACT FROM AUTHOR]

Whilst online learning has gained rapid momentum, the development of online technology and practices that support the delivery of online courses with a large research component has been slow. In 2017, the School of Psychological Sciences at Monash University, Australia, developed a potentially scalable and transferable online research portal. This is an all-in-one platform that is designed to facilitate and support online research and research supervision, for supervisors and students. The research portal has evolved to currently provide research and research supervision support to over 700 online psychology students at the university. This paper describes the development, implementation and impact of the research portal and presents data from a preliminary evaluation of its usability and user satisfaction. Both research students and supervisors from the fully online fourth-year Graduate Diploma of Psychology Advanced program at Monash University participated in a series of focus groups, individual usability testing sessions, and surveys, and reported favourably on the research portal’s research supervisor and supervisee user satisfaction and usability. Qualitative and quantitative feedback provided useful information supporting research portal improvement and expansion possibilities, allowing an increasingly valuable contribution to online research supervision, research and research teaching. Implications for practice or policy • All research students will be able to complete their research-related professional training online. • Research supervisors and students will be able to access a standardised best practice online research supervision and research tool across courses and topics. • Course leaders will be able to expand online education with an online research supervision and research tool that supports all research programs. • Universities will be able to provide a research learning pathway for all students.

Background: Little is known about what drives older adults' motivation to change their behaviour and whether that is associated with their personal dementia risk profile. Our aims were to (i) understand what sociodemographic factors are associated with older Australians' motivation to change behaviour to reduce their dementia risk, and (ii) explore the relationship between socio-demographic factors and motivation to reduce dementia risk with health- and lifestyle-based dementia risk scores in older adults. Methods: A cross-sectional online postal or telephone survey was administered to community-dwelling older adults in New South Wales, Australia between January and March 2021. Measures included socioeconomic status, locality, and health status, the Motivation to Change Lifestyle and Health Behaviours for Dementia Risk Reduction (MCLHB-DRR) scale and the lifestyle-based dementia risk score (LIBRA index). Multiple linear regression analyses were used to explore the associations for (i) sociodemographic factors and motivation to reduce dementia risk (MCLHB-DRR scales) and (ii) sociodemographic factors and motivation to reduce dementia risk with health- and lifestyle-based dementia risk (LIBRA index). Results: A total of 857 older adults (mean age 73.3 years, SD = 6.0, range 65–94; 70% women; 34.6% less than grade 6 education) completed the survey. Respondents reported high levels of motivation to adopt behaviour changes, agreeing on the importance of good health. Individuals who were younger were more likely to have greater motivation to modify lifestyle to reduce dementia risk and had higher perceived benefits to gain by adopting a healthy lifestyle. Dementia risk scores were moderately low (mean LIBRA index =− 2.8 [SD = 2.0], range − 5.9–3.8), indicating relatively moderate-to-good brain health. Men with low socioeconomic status and higher perceived barriers to lifestyle change had higher dementia risk scores. Conclusions: Public health campaigns need to overcome motivational barriers to support reductions in dementia risk. A multifaceted and inclusive approach targeting both sociodemographic differences and impediments to brain healthy lifestyles is required to achieve genuine change.

Measurement invariance underlies construct validity generalization in psychology and must be demonstrated prior to any cross-population comparison of means and validity correlations. The purpose of this study was to evaluate the measurement invariance of the Wechsler Intelligence Scale for Children–Fifth Edition (WISC-V) across Australia and New Zealand (A&NZ) versus the U.S. normative samples. The WISC-V is the most widely used assessment of intelligence in children. Participants were census matched, nationally representative samples from A&NZ (n = 528) and the United States (n = 2,200) who completed the WISC-V standardization version. Baseline model estimation was conducted to ensure the same model showed acceptable fit in both samples separately. Measurement invariance was then examined across A&NZ and United States. The five-factor scoring model described in the test manual showed excellent fit in both samples. Results showed that the WISC-V demonstrated strict metric measurement invariance across the A&NZ and U.S. samples. Further, the results were consistent with the Cattell–Horn–Carroll (CHC) framework of cognitive abilities, indicating the generalizability of cognitive abilities across cultures. Small but significant differences in visual spatial latent means were found across females, highlighting the importance of local normative data. These findings suggest that the WISC-V scores can be meaningfully compared across A&NZ and United States and that the constructs, which align with CHC theory, and associated construct validity research, generalize across countries. Public Significance Statement: This study examined the generalizability of the WISC-V, the most widely used intelligence test for children, across nationally representative samples from A&NZ and the United States. The results suggest that WISC-V scores can be meaningfully compared across A&NZ and U.S. children and that the psychological constructs measured by the WISC-V generalize across countries. However, small mean score differences highlight the importance of local normative data. [ABSTRACT FROM AUTHOR]

Predation is important in maintaining the community structure, functioning and ecological resilience of estuarine seascapes. Understanding how predator community structure, seascape context and habitat condition combine to influence predation is vital in managing estuarine ecosystems. We measured relationships between predator species richness, predator abundance and individual species abundances as well as seascape context and habitat condition, on relative predation probability in mangrove forests, seagrass meadows and unvegetated sediment across 11 estuaries in Queensland, Australia. Predation was quantified using videoed assays of tethered invertebrates (i.e. ghost nippers, Trypaea australiensis) and fish assemblages were surveyed using remote underwater video systems. Yellowfin bream (Acanthopagrus australis) dominated predation in all three habitats; however, predation was not correlated with yellowfin bream abundance. Instead, predation increased fourfold in mangroves and threefold in unvegetated sediment when predatory species richness was highest (> 3 species), and increased threefold in seagrass when predator abundance was highest (> 10 individuals). Predation in mangroves increased fourfold in forests with a lower pneumatophore density (< 50/m
2 ). In seagrass, predation increased threefold at sites that had a greater extent (> 2000 m2 ) of seagrass, with longer shoot lengths (> 30 cm) and at sites that were closer to (< 2000 m) the estuary mouth. Predation on unvegetated sediment increased threefold when more extensive salt marshes (> 15000 m2 ) were nearby. These findings demonstrate the importance of predator richness and abundance in supplementing predation in estuaries, despite the dominance of a single species, and highlight how seascape context and habitat condition can have strong effects on predation in estuaries.

Disentangling natural and anthropogenic effects on ecosystem condition can uncover bright spots in urban landscapes that are performing above expectations and so are potential sites for conservation or benchmarking, as well as sites performing below expectations that should be the focus of management. In this study, we tested for correlations between metrics indexing ecological condition (focusing on habitat-forming species) and a suite of spatial and environmental variables at 373 sites across four ecosystems (mangroves, seagrass, saltmarsh and rocky outcrops) and 13 estuaries in southeast Queensland, Australia. Ten condition metrics across the four ecosystems correlated with variables indexing the seascape context of sites, with condition metrics typically higher at sites more connected to natural features including the estuary mouth and mangroves. Urbanisation affected only two metrics, with rocky outcrop oyster cover being 75% lower at sites near extensive urbanisation and algae cover being highest at sites with intermediate urbanisation. We identified patterns in at least two variables from each ecosystem, meaning that decisions need to be made regarding optimal ecosystem states. Overall, management sites were more common than bright spots, with 50% more management sites in mangroves, 42.8% more in seagrasses, 38.5% more in saltmarshes and no bright spots in rocky outcrops (however, 10.3% of rocky outcrop sites were bright spots under an alternate ecosystem state model). We found that patterns in habitat condition across coastal seascapes can be predicted using spatial modelling approaches, and that these models can be readily used to prioritise management actions across the entire regions.
