Talking about money: public participation and expert knowledge in the Euro referendum

This paper uses the proposed UK referendum on the single European currency as a means of investigating the effect of democratizing science on the scrutiny of conflicting expert advice. Although the referendum has not happened yet, and may not happen at all, the campaigners for and against the Euro have none the less been working for several years to ensure that if, and when, it does happen they are in a position to win it. By exploring how campaigners on both sides of the debate understand the concerns of voters, the paper shows how they are working towards a referendum in which the political dimensions of the Euro are actively minimized in order to avoid alienating key 'floating voters'. Instead, the campaign is expected to focus on the economic costs and benefits of the Euro for individuals and households, with only limited discussion of issues relating to sovereignty. Whether or not the campaign groups, particularly those that oppose the Euro, can maintain this line remains to be seen but if there is a full and frank public debate about the economic, social and political stakes, then this will be despite the referendum rather than because of it.     

Rural and urban women's perceptions of barriers to health, mental health, and criminal justice services: implications for victim services

The purpose of this study was to examine rural and urban women's perceptions of barriers to health and mental health services as well as barriers to criminal justice system services. Eight focus groups were conducted, two in a selected urban county (n = 30 women) and two in each of three selected rural counties (n = 98 women). Results were classified into a barrier framework developed in the health service utilization literature which suggests there are four main dimensions of barriers: affordability, availability, accessibility, and acceptability. Results indicate that: (1) women face many barriers to service use including affordability, availability, accessibility, and acceptability barriers; (2) it takes an inordinate level of effort to obtain all kinds of services; however, women with victimization histories may face additional barriers over and above women without victimization histories; (3) barriers to health and mental health service utilization overlap with barriers to utilizing the criminal justice system; and (4) there are many similarities in barriers to service use among rural and urban women; however, there are some important differences suggesting barriers are contextual. Future research is needed to further clarify barriers to service use for women with victimization histories in general, and specifically for rural and urban women. In addition, future research is needed to better understand how women cope with victimization in the context of the specific barriers they face in their communities.     

Motivators for Change and Barriers to Help-Seeking in Australian Problem Gamblers

Although prevalence studies consistently indicate that many thousands of Australians experience gambling-related problems, only a relatively small proportion of these people seek professional help. This study examines the principal motivations for, and impediments to, help-seeking in a sample of 77 problem gamblers recruited from agencies and the general community. The results indicated that profession help-seeking is predominantly crisis-driven rather than being motived by a gradual recognition of problematic behaviour. Shame, denial and social factors were identified as the most significant barriers to change rather than a lack of knowledge, or dislike of, treatment agencies. The value of early interventions including the screening of gamblers in routine medical consultations and partner support strategies is discussed.     

LOWER BOUNDS FOR THE DIVERGENCE OF DIRECTIONAL AND AXIAL ESTIMATORS

Consider estimation of a unit vector parameter a in two classes of distributions. In the first, α is a direction. In the second, α is an axis, so that –α and α are equivalent: the aim is to obtain the projector αα^t. In each case the paper uses first principles to define measures of the divergence of such estimators and derives lower bounds for them. These bounds are computed explicitly for the Fisher-Von Mises and Scheidegger-Watson densities on the g-dimensional sphere, ω_q. In the latter case, the tightness of the bound is established by simulations.     

Women, men, VDU work and health: A questionnaire survey of British VDU operators

This paper presents the results of a questionnaire survey of male and female VDU operators distributed through Health & Safety at Work magazine. 3819 questionnaires were analysed using the SPSS computer program. 57% of the sample were female, 68% were under 35 years old and 73% were members of a trade union or staff association. The large number of male respondents meant that it was possible to compare work patterns, types of work and health effects for men and women. It appears that women are engaged in more repetitive and less varied tasks at the VDU and that they work longer hours and for longer periods without a break than men. The most frequently reported health problems were eyestrain, painful or stiff neck and shoulders, fatigue and irritated eyes. The incidence of symptoms was related to hours of work at the VDU. Women were more likely to report health effects than men. This difference remains when hours of work, type of work and hours worked without a break are taken into account. Ergonomically designed equipment such as adjustable chairs, lighting or keyboard did not have an obvious effect on the reporting of symptoms. It appeared that there is a complex interaction between the physical, ergonomic and psychosocial factors associated with new technology. All these factors need to be taken into account in further research into the health problems of VDU operators.     

What Is Wrong with Criterion FN-Lines for Judging the Tolerability of Risk?

This paper is concerned with the intellectual framework in which judgments are made about the tolerability of so-called societal risk. The current practical approach is based on the position of the FN-curves representing the risks from hazardous systems in relation to criterion FN-lines. The objections to FN-criteria are that they can give unreasonable conclusions and that they are inconsistent. Statistical decision theory suggests an alternative and preferable rule of minimising the expected disutility, that is average harm, from accidents.

Limitations to Empirical Extrapolation Studies: The Case of BMD Ratios

Extrapolation relationships are of keen interest to chemical risk assessment in which they play a prominent role in translating experimentally derived (usually in animals) toxicity estimates into estimates more relevant to human populations. A standard approach for characterizing each extrapolation relies on ratios of pre-existing toxicity estimates. Applications of this "ratio approach" have overlooked several sources of error. This article examines the case of ratios of benchmark doses, trying to better understand their informativeness. The approach involves mathematically modeling the process by which the ratios are generated in practice. Both closed form and simulation-based models of this "data-generating process" (DGP) are developed, paying special attention to the influence of experimental design. The results show the potential for significant limits to informativeness, and revealing dependencies. Future applications of the ratio approach should take imprecision and bias into account. Bootstrap techniques are recommended for gauging imprecision, but more complicated techniques will be required for gauging bias (and capturing dependencies). Strategies for mitigating the errors are suggested.
