What is the evidence for harm minimisation measures in gambling venues?

What techniques are currently being used for electronic gambling machine harm minimisation, and do they work? Overview The use of electronic gambling machines (EGMs) in Australia and New Zealand constitutes the largest sector of the gambling industry. The costs arising from the harms of gambling detract significantly from its benefits, and in all Australian jurisdictions various policy measures have been implemented to reduce these harms. If successful, these would maximise the net benefits associated with EGM gambling. This article reviews the available evidence for a range of these practices, particularly those implemented within EGM venues via ‘codes of practice’. These codes of practice are intended to give effect to the principles of ‘responsible gambling’ within EGM venues. These measures are: self-exclusion, signage, messages, interaction with gamblers, the removal of ATMs from gambling venues, and ‘responsible gambling’ assessed overall in a venue context. In addition, we review the evidence in support of two major recommendations of the Productivity Commission’s 2010 report into gambling, pre-commitment and one-dollar maximum wagers. We conclude that there is a modest level of evidence supporting some measures, notably self-exclusion and, to a greater extent, the removal of ATMs. There is also some evidence that ‘responsible gambling’ measures have, collectively, reduced the harms associated with gambling. However, there is limited evidence available to confirm the effectiveness of most individual ‘responsible gambling’ measures actually implemented in venues. Further, policy measures implemented outside the control of venues (such as ATM removal, reduction in bet limits, and the prohibition of smoking) appear to be associated with more significant effects, based on analysis of EGM revenue data in Victoria. The evidence for prospective measures is necessarily limited since the ultimate test is post-implementation efficacy, but there is growing evidence to suggest that pre-commitment, one-dollar maximum bets or other machine design changes may yield significantly more effective harm minimisation effects than in-venue practices such as signage or, indeed, self-exclusion. In considering evidence about the effects of existing or prospective measures it is important to emphasise that packages of measures might be more effective than single ones, and that an inability to confirm a statistically significant effect does not mean that no effect exists.

The relevance and role of gaming machine games and game features on the play of problem gamblers

Prepared for the Independent Gambling Authority in South Australia, this report examines aspects of the relationship between gaming machine technology and problem gambling. It looks at: • whether particular gaming machine games feature more commonly in the play of problem gamblers as compared to recreational gamblers; • whether there are particular characteristics of those games that distinguish them from other games; • whether those differences are the characteristics that attract problem gamblers and feature in problem gambling play; • to what extent those characteristics affect the play of recreational gamblers; and • to what extent those characteristics feature in a gamblers’ transition from recreational to problem gambler

Effects of Compact Fluorescence Light (Cfl) Bulbs on Power Quality

In recent time, the power quality has attracted a lot of attention due to extensive emphasis by power utility on the power system efficiency and end users awareness of power quality issues. This has occurred mainly due to the sensitivity of the modern equipment and the deregulation of the power distribution. In addition, there are usually massive losses both to power utility and end users due to poor power quality supplies which fall below the set standards. Power quality primarily consists of voltage dip/ swell, power system interruptions, harmonic distortions, voltage flickers and frequency deviations.  This study looks at effect of CFL bulbs on power system in relation to harmonic distortions and low power factor inherently associated by CFL. It has established that the bulbs generate substantial harmonic distortions and leading power factor. Combination of incandescent and CFL bulbs in one circuit was noted to improves the power quality.

Improving Power Distribution Efficiency On Power Lines

This paper discusses the power factor of transmission and distribution lines for selected power utility substations. The choice of selection of lines was based on the nature of the load and the status of the loading. The data collected and analyzed revealed that some feeder lines at most of substations are distributing active power at low PF below the grid threshold limit. Feeder lines mainly supplying domestic loads have their PF generally low and on the other hand, it was found that feeder lines supplying industrial loads have power factor well above the statutory limit. It is concluded that it is imperative to compensate the reactive current on feeder lines supplying mainly domestic loads in the vicinity of the loads i.e. near the distribution transformers to improve the power factor of these feeder lines in order to increase distribution efficiency and improve the voltage profile.

On gambling research, social science and the consequences of commercial gambling

Social, political, economic, geographic and cultural processes related to the significant growth of the gambling industries have, in recent years, been the subject of a growing body of research. This body of research has highlighted relationships between social class and gambling expenditure, as well as the design, marketing and location of gambling products and businesses. It has also demonstrated the regressive nature of much gambling revenue, illuminating the influence that large gambling businesses have had on government policy and on researchers, including research priorities, agendas and outcomes. Recently, critics have contended that although such scholarship has produced important insights about the operations and effects of gambling businesses, it is ideologically motivated and lacks scientific rigour. This response explains some basic theoretical and disciplinary concepts that such critique misunderstands, and argues for the value of social, political, economic, geographic and cultural perspectives to the broader, interdisciplinary field of gambling research. © 2017 Informa UK Limited, trading as Taylor & Francis Group. **Please note that there are multiple authors for this article therefore only the name of the first 5 including Federation University Australia affiliate “Angela Rintoul” is provided in this record*

Terrain classification using circular polarimetric features

Conventional representations of polarization response are referred to a horizontally and vertically polarized basis. Recent studies by Freeman and Durden, van Zyl, and others suggest that alternative polarimetric features which more easily resolve the contributions of simple scattering mechanisms such as odd-bounce, even-bounce, and diffuse scattering could offer several advantages in terrain classification. The circular polarization covariance matrix is a potential source of such features. In this paper, we derive its relationship to the Stokes matrix, describe some of its properties, and compare the utility of linear and circular polarimetric features in classifying an AIRSAR scene containing urban, park, and ocean terrain

Safety and efficacy of mass drug administration with a single-dose triple-drug regimen of albendazole + diethylcarbamazine + ivermectin for lymphatic filariasis in Papua New Guinea: An open-label, cluster-randomised trial

BACKGROUND: Papua New Guinea (PNG) has a high burden of lymphatic filariasis (LF) caused by Wuchereria bancrofti, with an estimated 4.2 million people at risk of infection. A single co-administered dose of ivermectin, diethylcarbamazine and albendazole (IDA) has been shown to have superior efficacy in sustained clearance of microfilariae compared to diethylcarbamazine and albendazole (DA) in small clinical trials. A community-based cluster-randomised trial of DA versus IDA was conducted to compare the safety and efficacy of IDA and DA for LF in a moderately endemic, treatment-naive area in PNG. METHODOLOGY: All consenting, eligible residents of 24 villages in Bogia district, Madang Province, PNG were enrolled, screened for W. bancrofti antigenemia and microfilaria (Mf) and randomised to receive IDA (N = 2382) or DA (N = 2181) according to their village of residence. Adverse events (AE) were assessed by active follow-up for 2 days and passive follow-up for an additional 5 days. Antigen-positive participants were re-tested one year after MDA to assess treatment efficacy. PRINCIPAL FINDINGS: Of the 4,563 participants enrolled, 96% were assessed for AEs within 2 days after treatment. The overall frequency of AEs were similar after either DA (18%) or IDA (20%) treatment. For those individuals with AEs, 87% were mild (Grade 1), 13% were moderate (Grade 2) and there were no Grade 3, Grade 4, or serious AEs (SAEs). The frequency of AEs was greater in Mf-positive than Mf-negative individuals receiving IDA (39% vs 20% p\u3c0.001) and in Mf-positive participants treated with IDA (39%), compared to those treated with DA (24%, p = 0.023). One year after treatment, 64% (645/1013) of participants who were antigen-positive at baseline were re-screened and 74% of these participants (475/645) remained antigen positive. Clearance of Mf was achieved in 96% (52/54) of infected individuals in the IDA arm versus 84% (56/67) of infected individuals in the DA arm (relative risk (RR) 1.15; 95% CI, 1.02 to 1.30; p = 0.019). Participants receiving DA treatment had a 4-fold higher likelihood of failing to clear Mf (RR 4.67 (95% CI: 1.05 to 20.67; p = 0.043). In the DA arm, a significant predictor of failure to clear was baseline Mf density (RR 1.54; 95% CI, 1.09 to 2.88; p = 0.007). CONCLUSION: IDA was well tolerated and more effective than DA for clearing Mf. Widespread use of this regimen could accelerate LF elimination in PNG.
