Drink driving among Aboriginal and Torres Strait Islander Australians: what has been done and where to next?
The Australian Government will set the direction for addressing road safety over the next decade with its 2021–2030 National Road Safety Strategy. This road map will detail objectives and goals agreed upon by all Australian states and territories. Similar to previous national strategies, Aboriginal and Torres Strait Islander (Indigenous) Australians are a high priority population. Indigenous Australians are over-represented in serious injury and fatal road crashes, with alcohol a leading factor. Therapeutic and educational programs are a major strategy among the suite of measures designed to reduce and prevent drink driving in Australia. The release of this new strategy provides a timely opportunity to reflect on what is known about drink driving among Indigenous Australians and to consider the suitability of existing therapeutic and educational drink driving programs for Indigenous Australian contexts. Here, we summarise factors that contribute to drink driving in this population and identify outstanding knowledge gaps. Then, we present an overview of drink driving programs available for Indigenous Australians along with suggestions for why tailored programs are needed to suit local contexts. The response to address drink driving among Indigenous Australians has been fragmented Australia-wide. A coordinated national response, with ongoing monitoring and evaluation, would improve policy effectiveness and inform more efficient allocation of resources. Together this information can help create suitable and effective drink driving programs for Indigenous drivers and communities Australia-wide
New Lower Bounds on the Self-Avoiding-Walk Connective Constant
We give an elementary new method for obtaining rigorous lower bounds on the
connective constant for self-avoiding walks on the hypercubic lattice .
The method is based on loop erasure and restoration, and does not require exact
enumeration data. Our bounds are best for high , and in fact agree with the
first four terms of the expansion for the connective constant. The bounds
are the best to date for dimensions , but do not produce good results
in two dimensions. For , respectively, our lower bound is within
2.4\%, 0.43\%, 0.12\%, 0.044\% of the value estimated by series extrapolation.Comment: 35 pages, 388480 bytes Postscript, NYU-TH-93/02/0
Critical Exponents, Hyperscaling and Universal Amplitude Ratios for Two- and Three-Dimensional Self-Avoiding Walks
We make a high-precision Monte Carlo study of two- and three-dimensional
self-avoiding walks (SAWs) of length up to 80000 steps, using the pivot
algorithm and the Karp-Luby algorithm. We study the critical exponents
and as well as several universal amplitude ratios; in
particular, we make an extremely sensitive test of the hyperscaling relation
. In two dimensions, we confirm the predicted
exponent and the hyperscaling relation; we estimate the universal
ratios , and (68\% confidence
limits). In three dimensions, we estimate with a
correction-to-scaling exponent (subjective 68\%
confidence limits). This value for agrees excellently with the
field-theoretic renormalization-group prediction, but there is some discrepancy
for . Earlier Monte Carlo estimates of , which were , are now seen to be biased by corrections to scaling. We estimate the
universal ratios and ; since , hyperscaling holds. The approach to
is from above, contrary to the prediction of the two-parameter
renormalization-group theory. We critically reexamine this theory, and explain
where the error lies.Comment: 87 pages including 12 figures, 1029558 bytes Postscript

The Main Belt Comets and ice in the Solar System
We review the evidence for buried ice in the asteroid belt; specifically the questions around the so-called Main Belt Comets (MBCs). We summarise the evidence for water throughout the Solar System, and describe the various methods for detecting it, including remote sensing from ultraviolet to radio wavelengths. We review progress in the first decade of study of MBCs, including observations, modelling of ice survival, and discussion on their origins. We then look at which methods will likely be most effective for further progress, including the key challenge of direct detection of (escaping) water in these bodies

Study protocol: cross-national comparative case study of recovery-focused mental health care planning and coordination (COCAPP).
BACKGROUND: The collaborative care planning study (COCAPP) is a cross-national comparative study of care planning and coordination in community mental healthcare settings. The context and delivery of mental health care is diverging between the countries of England and Wales whilst retaining points of common interest, hence providing a rich geographical comparison for research. Across England the key vehicle for the provision of recovery-focused, personalised, collaborative mental health care is the care programme approach (CPA). The CPA is a form of case management introduced in England in 1991, then revised in 2008. In Wales the CPA was introduced in 2003 but has now been superseded by The Mental Health (Care Co-ordination and Care and Treatment Planning) (CTP) Regulations (Mental Health Measure), a new statutory framework. In both countries, the CPA/CTP requires providers to: comprehensively assess health/social care needs and risks; develop a written care plan (which may incorporate risk assessments, crisis and contingency plans, advanced directives, relapse prevention plans, etc.) in collaboration with the service user and carer(s); allocate a care coordinator; and regularly review care. The overarching aim of this study is to identify and describe the factors that ensure CPA/CTP care planning and coordination is personalised, recovery-focused and conducted collaboratively. METHODS/DESIGN: COCAPP will employ a concurrent transformative mixed methods approach with embedded case studies. Phase 1 (Macro-level) will consider the national context through a meta-narrative mapping (MNM) review of national policies and the relevant research literature. Phase 2 (Meso-level and Micro-level) will include in-depth micro-level case studies of everyday 'frontline' practice and experience with detailed qualitative data from interviews and reviews of individual care plans. This will be nested within larger meso-level survey datasets, senior-level interviews and policy reviews in order to provide potential explanations and understanding. DISCUSSION: COCAPP will help identify the key components that support and hinder the provision of personalised, recovery-focused care planning and provide an informed rationale for a future planned intervention and evaluation
The food superstore revolution: changing times, changing research agendas in the UK
This paper considers the changing scope of research into UK food superstores over a 30-year period. Rather than catalogue changing market shares by format, we seek instead to show how change links to national policy agendas. Academic research has evolved to address the growing complexities of the social, technological, economic and political impacts of the superstore format. We exemplify this by tracing the progression of retail change in Portsmouth, Hampshire, over 30 years. We discover that academic research can conflict with the preconceptions of some public policymakers. The position is exacerbated by a progressive decline in public information – and a commensurate rise in factual data held by commercial data companies – that leaves policymakers with a choice of which data to believe. This casts a shadow over the objectivity of macro-policy as currently formulated. Concerns currently arise because the UK Competition Commission (2008 but ongoing) starts each inquiry afresh with a search for recent data. Furthermore, it has recently called for changes to retail planning – the very arena in which UK superstore research commenced

Care planning for consumers on community treatment orders: an integrative literature review
Background
Case management is the established model for care provision in mental health and is delivered within current care philosophies of person-centred and recovery-oriented care. The fact that people with a mental illness may be forced to receive care and treatment in the community poses challenges for clinicians aiming to engage in approaches that promote shared decision-making and self-determination. This review sought to gain an in-depth understanding of stakeholders’ perspectives and experiences of care planning for consumers’ on CTOs.
Methods
An integrative review method allowed for inclusion of a broad range of studies from diverse empirical sources. Systematic searches were conducted across six databases. Following appraisal, findings from included papers were coded into groups and presented against a framework of case management.
Results
Forty-eight papers were included in the review. Empirical studies came from seven countries, with the majority reporting on qualitative methods. Many similarities were reported across studies. Positive gains from CTOs were usually associated with the nature of support received, highlighting the importance of the therapeutic relationship in care planning. Key gaps in care planning included a lack of connection between CTO, treatment and consumer goals and lack of implementation of focussed interventions.
Conclusions
Current case management processes could be better utilised for consumers on CTOs, with exploration of how this could be achieved warranted. Workers need to be sensitive to the ‘control and care’ dynamic in the care planning relationship, with person-centred approaches requiring core and advanced practitioner and communication skills, including empathy and trust
Patterns and correlates of patient-reported helpfulness of treatment for common mental and substance use disorders in the WHO World Mental Health Surveys
Patient-reported helpfulness of treatment is an important indicator of quality in patient-centered care. We examined its pathways and predictors among respondents to household surveys who reported ever receiving treatment for major depression, generalized anxiety disorder, social phobia, specific phobia, post-traumatic stress disorder, bipolar disorder, or alcohol use disorder. Data came from 30 community epidemiological surveys - 17 in high-income countries (HICs) and 13 in low- and middle-income countries (LMICs) - carried out as part of the World Health Organization (WHO)'s World Mental Health (WMH) Surveys. Respondents were asked whether treatment of each disorder was ever helpful and, if so, the number of professionals seen before receiving helpful treatment. Across all surveys and diagnostic categories, 26.1% of patients (N=10,035) reported being helped by the very first professional they saw. Persisting to a second professional after a first unhelpful treatment brought the cumulative probability of receiving helpful treatment to 51.2%. If patients persisted with up through eight professionals, the cumulative probability rose to 90.6%. However, only an estimated 22.8% of patients would have persisted in seeing these many professionals after repeatedly receiving treatments they considered not helpful. Although the proportion of individuals with disorders who sought treatment was higher and they were more persistent in HICs than LMICs, proportional helpfulness among treated cases was no different between HICs and LMICs. A wide range of predictors of perceived treatment helpfulness were found, some of them consistent across diagnostic categories and others unique to specific disorders. These results provide novel information about patient evaluations of treatment across diagnoses and countries varying in income level, and suggest that a critical issue in improving the quality of care for mental disorders should be fostering persistence in professional help-seeking if earlier treatments are not helpful
