An individual based model of female brown crab movements in the western English channel: modelling migration behaviour

An individual based model (IBM) of the female brown crab Cancer pagurus population exploited off South Devon, UK is described. Size dependent movement rules are ascribed to individuals based on previous observations of predominantly westward migration down the English Channel. Two additional versions of the movement rules explored whether the empirically derived rule was necessary to model the temporal and spatial distribution of crabs. Local crab movement was dependent on substrate type and water depth. Females prefer a soft substrate in which they can bury when temperatures are low or they have eggs to incubate. Crabs have size dependent depth preferences with larger crabs preferring greater depths. Two recruitment functions are used which relate the number of incoming crabs to the sea surface temperature five years earlier. Model outputs were tested against 10 years of logbook data from three crab fishers and against data from a year-long sampling programme on eight of the vessels exploiting the area. The model reproduces the long-term pattern which is mostly temperature driven. Spatial variation in catch is captured effectively by the model with more crabs being caught in the east of the area than the west and more caught offshore than inshore. The significance of the results is discussed in relation to the crab life cycle, management of the fishery and the potential effects of increasing temperatures

Mental health in the island nations of the Western Pacific: A rapid review of the literature

© The Royal Australian and New Zealand College of Psychiatrists 2015.OBJECTIVES: The aim of the study was to identify mental-health-relevant literature accessible to policy makers and healthcare workers in the island nations of the Western Pacific.METHODS: Material collated to support the inaugural Leadership in Mental Health: Island Nations course held in Cairns in May 2015 was used as the basis of a "rapid review".RESULTS: The rapid review considered 303 documents identified by a search carried out using James Cook University's OneSearch, Google Scholar, and the authors' knowledge. Search terms included mental health and the like, and terms with Pacific and current Pacific island country names. Findings were classified by region/country, year of release/publication, mental health issue addressed, peer-reviewed or grey literature, and type of study. Almost half of the findings had been released in the previous five years. However, only 36% were peer-reviewed publications and only 3.6% of the findings were intervention studies.CONCLUSIONS: There is limited easily accessible documentation to confidently direct practice or policies regarding which strategies are likely to be effective in responding to the high rates of mental ill-health experienced in the Pacific island nations, or to plan for increases as a consequence of rapid social and demographic changes that are transforming Pacific island societies

Towards best practice during COVID-19: A responsive and relational program with remote schools to enhance the wellbeing of Aboriginal and Torres Strait Islander students

Purpose: From 2018, the Schools Up North (SUN) programme worked with three remote Australian schools to enhance their capability and resilience to support the wellbeing and mental health of Aboriginal and Torres Strait Islander students and staff. This paper explores the implementation of SUN during the first two years of COVID-19 (2020–2021). Method: Using grounded theory methods, school staff, other service providers and SUN facilitators were interviewed, with transcripts and programme documents coded and interrelationships between codes identified. An implementation model was developed. Results: The SUN approach was place-based, locally informed and relational, fostering school resilience through staff reflection on and response to emerging contextual challenges. Challenges were the: community lockdowns and school closures; (un)availability of other services; community uncertainty and anxiety; school staff capability and wellbeing; and risk of educational slippage. SUN strategies were: enhancing teachers’ capabilities and resources, facilitating public health discussions, and advocating at regional level. Outcomes were: enhanced capability of school staff; greater school-community engagement; student belonging and engagement; a voice for advocacy; and continuity of SUN's momentum. Conclusions: The resilience approach (rather than specific strategies) was critical for building schools’ capabilities for promoting students and staff wellbeing and provides an exemplar for remote schools globally

The cost of hospitalisation for youth self-harm: Differences across age groups, sex, Indigenous and non-Indigenous populations

Objective: To report the comparative rates, average length of stay and cost per episode of hospital management for self-harm in three age cohorts: 15–19 years, 20–24 years and 25–29 years; by sex and indigeneity. Design, setting, participants: A secondary data analysis of the Australian Institute of Health and Welfare (AIHW) dataset between 1st January 2014 and 31st December 2014 inclusive. Main outcome measures: Cost per episode of hospitalised self-harm and rates by age group, sex and Indigenous status. Results: The rate of hospitalised self-harm among Australian youth was 254.0 per 100,000 population. This rate resulted in an annual cost to the healthcare system of AU$55 million or an average cost per episode of$4649 (95% CI $4488:$4810). Hospitalised self-harm was 21 times higher than the rate of suicide (11,820 episodes of hospitalised self-harm/564 suicides). Indigenous youth had on average a 1.4 times higher rate of hospitalised self-harm and 2.2 times higher rate of suicide than non-Indigenous counterparts. When controlling for age and sex, the average cost per episode was significantly lower for Indigenous youth compared to non-Indigenous youth, estimated marginal means $4538 and$4954, respectively (p < 0.001). Conclusions: Hospitalised self-harm among Australian youth resulted in a substantial cost to the healthcare system. This cost is only part of the overall burden associated with self-harm. The rate of hospitalised self-harm was significantly higher in Indigenous youth, but the associated cost per episode was significantly lower. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature

The development of a survey instrument to assess Aboriginal and Torres Strait Islander students’ resilience and risk for self-harm

Background: Australian policies for Aboriginal and Torres Strait Islander well-being outline the importance of local community-based interventions; for adolescents, school-based programs have been identified as beneficial. However, there is a lack of localized data to determine levels of resilience and risk and thus whether programs are effective. This paper describes the challenges and opportunities in collaboratively designing and piloting a localized survey instrument to measure Indigenous students’ resilience and upstream risk factors for self-harm and the resultant instrument. Methods: A participatory action research approach was used to engage education staff, health-care providers, students, and researchers to design and pilot the survey instrument. A six-phased process facilitated survey development: (1) defining the logic and exploring the evidence; (2) understanding and tailoring for context; (3) testing for feasibility and relevance; (4) testing for appropriateness and comprehension; (5) facilitating survey administration; and (6) refining the instrument. Processes in each phase were recorded and transcribed with thematic analysis used to identify key challenges and opportunities arising during development. Results: Four key challenges and opportunities were identified: (1) the relevance of international survey instruments for Indigenous Australian students; (2) accounting for distinct environments; (3) the balance between assessing risk and protective factors; and (4) tailoring for literacy levels and school engagement. The final Student Survey instrument comprised 4 demographic and 56 resilience, risk, service use, and satisfaction questions. The T4S will be administered routinely on annual student intake. Discussion and conclusion: The six-phased participatory processes resulted in a tailored instrument that could identify the critical resilience and upstream risk factors facing a cohort of Indigenous students who attend boarding schools for secondary education. Challenges were resolved collaboratively and the pilot results were directly translated to education practice and its integration with health services. Our results suggest that both the phased process of developing the T4S and the instrument itself can be adapted for other Indigenous adolescent well-being and/or self-harm prevention programs

Validation and factor analysis of the Child and Youth Resilience Measure for Indigenous Australian boarding school students

Introduction: Resilience is a strengths-based construct that is useful for understanding differences in health and wellbeing among youth. There are a range of validated survey instruments available to measure resilience for Aboriginal and Torres Strait Islander (hereafter respectfully Indigenous1) youth. However, standard international instruments should only be used if they have been subjected to a rigorous cross-cultural adaptation process and psychometric evaluation in the target population to ensure their validity. The aim of the study was to validate an adapted Child and Youth Resilience Measure (CYRM-28) within a sample of Indigenous Australian boarding school students. Method: The CYRM-28, augmented with an additional 11 site specific items was administered to a purposive sample of Australian Indigenous boarding school students (n = 233) as part of the broader T4S survey instrument that captures demographic information and measures resilience, psychological distress and risk, and service usage. Confirmatory factor analysis was undertaken to verify the relationship between the observed variables with the theoretical constructs of the CYRM-28 and previous findings on the factor structure. Cronbach alpha was also calculated to assess the internal consistency of the CYRM-28 within this sample. Results: Survey data were not a good fit for any previously identified models of the CYRM-28, although the inclusion of a site-specific variable improved the overall fit statistics. Two separate scales were confirmed that capture the sources and expressions of resilience for Indigenous Australian boarding school students. This structure is different to previous findings in relation to the CYRM-28, but consistent with conceptualizations of resilience as a dynamic process
