Land cover and fire accounts to support Indigenous land management: A pilot study of Yawuru Country.

Ecosystem accounting is emerging as a promising tool for environmental management by offering consistent information about ecosystem change over time. Via a United Nations process, ecosystem accounting has been standardised in the System of Environmental-Economic Accounting (SEEA). However, there are currently no examples of ecosystem accounts developed specifically to support Indigenous people's management of land or sea. More than 40% (3 million square kilometres) of Australia's land and sea territory has Indigenous Title. If Indigenous managers are to use ecosystem accounting, then it is essential for them to be involved in its development. We assessed how ecosystem accounts can be developed and applied in a manner that supports the management objectives of Indigenous owners and managers. Working collaboratively with the Yawuru Traditional Owners of the land and sea country around Broome, Western Australia, we constructed and assessed experimental ecosystem accounts for land cover and fire for the period 2000-2020. Three key benefits of ecosystem accounts for supporting the priorities of Yawuru managers were identified: (1) flexibility in the units used for the analysis; (2) the extended time scale of the accounts; and (3) the emphasis on consistent capturing and reporting of data. We also identified the need for further work to incorporate cultural knowledge and values within the broader SEEA, with implications for the recognition of Indigenous people, knowledge and values within accounting systems globally.

Understanding the spatial diversity of social uses, dynamics, and conflicts in marine spatial planning.

Marine coastal environments are often socially complex public areas that need equitable spatial planning approaches. Understanding the extent of extractive and non-extractive uses and the social dynamics that may be driving patterns of use is essential if the spatial plan is to support the social resilience of a marine area. In this study, a combination of fuzzy-set multi-criteria GIS modelling and negative tie social network analysis were used to explore social uses and conflicts based on sketch-mapping interviews with five key stakeholder groups (ecotourism, Aboriginal Traditional Owners, commercial and recreational fishing, and water sports) within a Marine Protected Area (MPA). Most of the areas within the MPA were regularly used by the stakeholders, with non-extractive and extractive stakeholders occupying similar spatial extents, with each stakeholder group having a different pattern of use. However, stakeholder groups had different levels of perceived priority to access these areas and support of the current spatial management plan, especially within the ecotourism and Aboriginal Traditional Owner groups. The investigation of social conflicts in shaping patterns of use revealed that most stakeholder conflicts do not necessarily occur in areas of overlaps, but generally in areas of high biodiversity and easy access through marine infrastructure. Ecotourism groups had the most perceived conflicts over marine space, which shaped their use towards certain no-take zones that protected high biodiversity and would also provide protection from other conflicting stakeholder uses (e.g., boating, fishing). Overall, the method outlined in this paper presents a way for marine spatial management to consider not only the extent and diversity of social uses in a marine environment but also the spatial-social dynamics that may determine the success of the spatial plan in supporting long-term social resilience.

Migraine photophobia originating in cone-driven retinal pathways.

Migraine headache is uniquely exacerbated by light. Using psychophysical assessments in patients with normal eyesight we found that green light exacerbates migraine headache significantly less than white, blue, amber or red lights. To delineate mechanisms, we used electroretinography and visual evoked potential recording in patients, and multi-unit recording of dura- and light-sensitive thalamic neurons in rats to show that green activates cone-driven retinal pathways to a lesser extent than white, blue and red; that thalamic neurons are most responsive to blue and least responsive to green; and that cortical responses to green are significantly smaller than those generated by blue, amber and red lights. These findings suggest that patients' experience with colour and migraine photophobia could originate in cone-driven retinal pathways, fine-tuned in relay thalamic neurons outside the main visual pathway, and preserved by the cortex. Additionally, the findings provide substrate for the soothing effects of green light.

A meta-regression analysis of 41 Australian problem gambling prevalence estimates and their relationship to total spending on electronic gaming machines.

BACKGROUND: Many jurisdictions regularly conduct surveys to estimate the prevalence of problem gambling in their adult populations. However, the comparison of such estimates is problematic due to methodological variations between studies. Total consumption theory suggests that an association between mean electronic gaming machine (EGM) and casino gambling losses and problem gambling prevalence estimates may exist. If this is the case, then changes in EGM losses may be used as a proxy indicator for changes in problem gambling prevalence. To test for this association this study examines the relationship between aggregated losses on electronic gaming machines (EGMs) and problem gambling prevalence estimates for Australian states and territories between 1994 and 2016. METHODS: A Bayesian meta-regression analysis of 41 cross-sectional problem gambling prevalence estimates was undertaken using EGM gambling losses, year of survey and methodological variations as predictor variables. General population studies of adults in Australian states and territory published before 1 July 2016 were considered in scope. 41 studies were identified, with a total of 267,367 participants. Problem gambling prevalence, moderate-risk problem gambling prevalence, problem gambling screen, administration mode and frequency threshold were extracted from surveys. Administrative data on EGM and casino gambling loss data were extracted from government reports and expressed as the proportion of household disposable income lost. RESULTS: Money lost on EGMs is correlated with problem gambling prevalence. An increase of 1% of household disposable income lost on EGMs and in casinos was associated with problem gambling prevalence estimates that were 1.33 times higher [95% credible interval 1.04, 1.71]. There was no clear association between EGM losses and moderate-risk problem gambling prevalence estimates. Moderate-risk problem gambling prevalence estimates were not explained by the models (I 2 ≥ 0.97; R 2 ≤ 0.01). CONCLUSIONS: The present study adds to the weight of evidence that EGM losses are associated with the prevalence of problem gambling. No patterns were evident among moderate-risk problem gambling prevalence estimates, suggesting that this measure is either subject to pronounced measurement error or lacks construct validity. The high degree of residual heterogeneity raises questions about the validity of comparing problem gambling prevalence estimates, even after adjusting for methodological variations between studies.

An Indigenous perspective on ecosystem accounting: Challenges and opportunities revealed by an Australian case study.

The System of Environmental-Economic Accounting Ecosystem Accounting (SEEA-EA) is widely promoted in environmental and economic policy and management. Unfortunately, the SEEA-EA has not substantively addressed the aspects of accounting that may be of interest to, or used by, Indigenous peoples. We investigate an Indigenous perspective on the potential of the SEEA-EA to support cultural and environmental management through collaborative workshops with managers of Nyamba Buru Yawuru, the Prescribed Body Corporate representing the Yawuru Traditional Owners in Western Australia. Our discussions highlight that while the SEEA-EA may be a valuable tool for empowering Indigenous people and supporting the management of their lands and seas, there are areas where the SEEA-EA needs to be broadened to better reflect cultural values, and the services to ecosystems provided by Indigenous peoples. Embedding Indigenous perspectives into the SEEA-EA would mean that it is of greater use to Indigenous peoples and their representative organisations and ensure that these values are better recognised in the policymaking of government.

Improving spatial microsimulation estimates of health outcomes by including geographic indicators of health behaviour: The example of problem gambling.

Gambling is an important public health issue, with recent estimates ranking it as the third largest contributor of disability adjusted life years lost to ill-health. However, no studies to date have estimated the spatial distribution of gambling-related harm in small areas on the basis of surveys of problem gambling. This study extends spatial microsimulation approaches to include a spatially-referenced measure of health behaviour as a constraint variable in order to better estimate the spatial distribution of problem gambling. Specifically, this study allocates georeferenced electronic gaming machine expenditure data to small residential areas using a Huff model. This study demonstrates how the incorporation of auxiliary spatial data on health behaviours such as gambling expenditure can improve spatial microsimulation estimates of health outcomes like problem gambling.

The relationship between player losses and gambling-related harm: evidence from nationally representative cross-sectional surveys in four countries.

BACKGROUND AND AIMS: Flaws in previous studies mean that findings of J-shaped risk curves for gambling should be disregarded. The current study aims to estimate the shape of risk curves for gambling losses and risk of gambling-related harm (a) for total gambling losses and (b) disaggregated by gambling activity. DESIGN: Four cross-sectional surveys. SETTING: Nationally representative surveys of adults in Australia (1999), Canada (2000), Finland (2011) and Norway (2002). PARTICIPANTS: A total of 10 632 Australian adults, 3120 Canadian adults, 4484 people aged 15-74 years in Finland and 5235 people aged 15-74 years in Norway. MEASUREMENTS: Problem gambling risk was measured using the modified South Oaks Gambling Screen, the NORC DSM Screen for Gambling Problems and the Problem Gambling Severity Index. FINDINGS: Risk curves for total gambling losses were estimated to be r-shaped in Australia {ß losses = 4.7 [95% confidence interval (CI) = 3.8, 6.5], ß losses(2 =) -7.6 (95% CI = -17.5, -4.5)}, Canada [ß losses = 2.0 (95% CI = 1.3, 3.9), ß losses(2 =) -3.9 (95% CI = -15.4, -2.2)] and Finland [ß losses = 3.6 (95% CI = 2.5, 7.5), ß losses(2 =) -4.4 (95% CI = -34.9, -2.4)] and linear in Norway [ß losses = 1.6 (95% CI = 0.6, 3.1), ß losses(2 =) -2.6 (95% CI = -12.6, 1.4)]. Risk curves for different gambling activities showed either linear, r-shaped or non-significant relationships. CONCLUSIONS: Player loss-risk curves for total gambling losses and for different gambling activities are likely to be linear or r-shaped. For total losses and electronic gaming machines, there is no evidence of a threshold below which increasing losses does not increase the risk of harm.

The relationship between electronic gaming machine accessibility and police-recorded domestic violence: A spatio-temporal analysis of 654 postcodes in Victoria, Australia, 2005-2014.

An emerging body of research has documented an association between problem gambling and domestic violence in a range of study populations and locations. Yet little research has analysed this relationship at ecological scales. This study investigates the proposition that gambling accessibility and the incidence of domestic violence might be linked. The association between police-recorded domestic violence and electronic gaming machine accessibility is described at the postcode level. Police recorded family incidents per 10,000 and domestic-violence related physical assault offenses per 10,000 were used as outcome variables. Electronic gaming machine accessibility was measured as electronic gaming machines per 10,000 and gambling venues per 100,000. Bayesian spatio-temporal mixed-effects models were used to estimate the associations between gambling accessibility and domestic violence, using annual postcode-level data in Victoria, Australia between 2005 and 2014, adjusting for a range of covariates. Significant associations of policy-relevant magnitudes were found between all domestic violence and EGM accessibility variables. Postcodes with no electronic gaming machines were associated with 20% (95% credibility interval [C.I.]: 15%, 24%) fewer family incidents per 10,000 and 30% (95% C.I.: 24%, 35%) fewer domestic-violence assaults per 10,000, when compared with postcodes with 75 electronic gaming machine per 10,000. The causal relations underlying these associations are unclear. Quasi-experimental research is required to determine if reducing gambling accessibility is likely to reduce the incidence of domestic violence.

The species composition and seasonal distribution of mosquitoes in vernal pools in suburban Montreal, Quebec.

A study was conducted in the spring and summer of 1998 to determine the invertebrate community in vernal pools on the western portion of the Island of Montreal. This paper examines the mosquitoes (Diptera: Culicidae) found in 10 pools. Fifteen species in 4 genera (Aedes, Anopheles, Culex, and Ochlerotatus) were collected and the seasonal distribution of each species was determined. Ochlerotatus stimulans was the most abundant species. Two peaks occurred in larval abundance, in late April and early July. Larvae were more abundant in the spring; larval density was higher later in the summer. The abundance of mosquitoes in these pools was similar to those found in remote regions of the province.

Gambling expenditure predicts harm: evidence from a venue-level study.

BACKGROUND AND AIMS: The Total Consumption Theory of gambling suggests that gambling expenditure is positively associated with gambling-related harm. We test the hypothesis that electronic gaming machine (EGM) expenditure predicts gambling-related harm at the level of the EGM venue. DESIGN: Cross-sectional analysis of survey and administrative data. SETTING: General urban adult population of the Northern Territory of Australia. PARTICIPANTS: The sample consisted of 7049 respondents to a mail-survey about venue visitation and gambling behaviour across 62 EGM venues. MEASUREMENTS: Gambling-related harm was defined as the endorsement of two or more items on the Problem Gambling Severity Index. We obtained venue-level EGM expenditure data from the local licensing authority for all venues in the study area. We compared the prevalence of gambling-related harm among patrons aggregated at the venue level with the estimated mean EGM expenditure for each adult resident in the venue's service area using a Huff model, correlation analysis and multivariate binomial regression. FINDINGS: Aggregated to the venue level (n = 62), per-capita EGM expenditure was correlated significantly with rates of gambling-related harm (r = 0.27, n = 62, P = 0.03). After adjusting for venue type and number of EGMs, an increase in mean per-capita monthly EGM expenditure from $AU10 to $AU150 was associated with a doubling in the prevalence of gambling-related harm from 9% (95% CI = 6-12%) to 18% (95% CI = 13-23%). CONCLUSIONS: As suggested by the Total Consumption Theory of gambling, aggregate patron electronic gaming machine expenditure predicts the prevalence of gambling-related harm at the venue level.

The relationship between alcohol consumption, gambling behaviour and problem gambling during a single visit to a gambling venue.

INTRODUCTION AND AIMS: Despite the well-documented comorbidity between disordered alcohol use and problem gambling, little is known about the co-occurrence of drinking and gambling in gambling venues. This paper appears to be the first to investigate the association between drinking and gambling behaviour among a large sample of gamblers during a specific, non-laboratory gambling episode. DESIGN AND METHODS: We conducted a mail survey of all available households in the Northern Territory of Australia, including questions on drinking and gambling behaviour on the last visit to a gambling venue. We estimate the effect of moderate (1-4 standard drinks) and risky (>4 standard drinks) alcohol consumption on gambling participation and gambling duration for both problem and non-problem gamblers using regression analysis of 7044 survey responses. RESULTS: The probability of participating in electronic gaming machine (EGM) gambling decreased with alcohol consumption for non-problem gamblers, while the probability of participating in TAB (Totalisator Agency Board, off-course totalisator) gambling increased with risky alcohol consumption for all gamblers. Alcohol consumption was not associated with EGM gambling participation for problem gamblers. Moderate alcohol consumption was negatively associated with EGM gambling duration, with a stronger effect observed for problem gamblers. DISCUSSION AND CONCLUSIONS: Moderate alcohol consumption is inversely correlated with both the duration of play and probability of participation for EGM gambling. Current laboratory studies do not predict the drinking-gambling behaviour of the general population in non-laboratory settings. Future research on alcohol and gambling co-occurrence must explicitly consider the drinking and gambling environment in order to produce policy-relevant findings.

Combined optical coherence tomography and electroretinography system for in vivo simultaneous morphological and functional imaging of the rodent retina.

A combined ultrahigh resolution optical coherence tomography (UHROCT) and a electroretinography (ERG) system is presented for simultaneous imaging of the retinal structure and physiological response to light stimulation in the rodent eye. The 1060-nm UHROCT system provides approximately 3x5 microm (axialxlateral) resolution in the rat retina and time resolution of 22 micros. A custom-designed light stimulator integrated into the UHROCT imaging probe provides light stimuli with user-selected color, duration, and intensity. The performance of the combined system is demonstrated in vivo in healthy rats, and in a rat model of drug-induced outer retinal degeneration. Experimental results show correlation between the observed structural and physiological changes in the healthy and degenerated retina.
