Does climate change information affect stated risks of pine beetle impacts on forests? An application of the exchangeability method

Risks are an essential feature of future climate change impacts. We explore whether knowledge that climate change might be the source of increasing pine beetle impacts on public or private forests affects stated risk estimates of damage, elicited using the exchangeability method. We find that across subjects the difference between public and private forest status does not influence stated risks, but the group told that global warming is the cause of pine beetle damage has significantly higher risk perceptions than the group not given this information.

Risks and benefits of selective (re)presentation of interviewees' talk:some insights from discourse analysis

Purpose: The purpose of this paper is to examine the quality of evidence collected during interview. Current UK national guidance on the interviewing of victims and witnesses recommends a phased approach, allowing the interviewee to deliver their free report before any questioning takes place, and stipulating that during this free report the interviewee should not be interrupted. Interviewers, therefore, often find it necessary during questioning to reactivate parts of the interviewee's free report for further elaboration. Design/methodology/approach: The first section of this paper draws on a collection of police interviews with women reporting rape, and discusses one method by which this is achieved - the indirect quotation of the interviewee by the interviewer - exploring the potential implications for the quality of evidence collected during this type of interview. The second section of the paper draws on the same data set and concerns itself with a particular method by which information provided by an interviewee has its meaning "fixed" by the interviewer. Findings: It is found that "formulating" is a recurrent practice arising from the need to clarify elements of the account for the benefit of what is termed the "overhearing audience" - in this context, the police scribe, CPS, and potentially the Court. Since the means by which this "fixing" is achieved necessarily involves the foregrounding of elements of the account deemed to be particularly salient at the expense of other elements which may be entirely deleted, formulations are rarely entirely neutral. Their production, therefore, has the potential to exert undue interviewer influence over the negotiated "final version" of interviewees' accounts. Originality/value: The paper highlights the fact that accurate re-presentations of interviewees' accounts are a crucial tool in ensuring smooth progression of interviews and that re-stated speech and formulation often have implications for the quality of evidence collected during significant witness interviews. © Emerald Group Publishing Limited.

Willingness to trial functional foods and vitamin supplements: the role of attitudes, subjective norms, and dread of risks

Australian non-users of vitamin supplements (N = 162) and functional foods (N = 226) responded to a questionnaire examining their attitudes, subjective norms, and perceived behavioural control from the Theory of Planned Behaviour (TPB), risk dread and risk familiarity, and willingness to engage in free product trials. The impact of participants’ gender and age was also examined. Attitude and subjective norms were significant determinants of non-users willingness to trial each of the health products. Participants’ dread of the risk associated with the product was also a determinant of willingness to use functional foods. The overall models predicted between 25% and 30% of the variance in people’s willingness to trial the products. The findings provided some support for the TPB in predicting people’s willingness to trial functional foods and vitamin supplements and suggested, for willingness to trial functional foods, that non-users are also influenced by their dread of the risk associated with product use.

The future of cognitive and behavioral therapies in the prevention and early management of psychosis : opportunities and risks

Behavioral and cognitive interventions for people with psychosis have a long and distinguished history, although the evidence for their application to young people remains limited. We anticipate that the next decades will show substantial research into psychological intervention for this population. Important targets will include the management of environmental stressors, reduction of substance misuse, and promotion of early treatment. Psychological management of positive symptoms, depression, and suicidal behavior will continue to be critical objectives. Important secondary prevention goals will be the retention of cognitive functioning, vocational options, social skills, and social network support, including appropriate family support. We expect primary prevention to include both universal programs and interventions for adolescents at particularly high risk. Technical innovations will include increasing use of Internet-based intervention and behavior cueing devices. Pressures for intervention brevity will continue, as will problems with the systematic delivery of effective procedures.

Value-mapping for major economic infrastructure projects

The establishment of corporate objectives regarding economic, environmental, social, and ethical responsibilities, to inform business practice, has been gaining credibility in the business sector since the early 1990’s. This is witnessed through (i) the formation of international forums for sustainable and accountable development, (ii) the emergence of standards, systems, and frameworks to provide common ground for regulatory and corporate dialogue, and (iii) the significant quantum of relevant popular and academic literature in a diverse range of disciplines. How then has this move towards greater corporate responsibility become evident in the provision of major urban infrastructure projects? The gap identified, in both academic literature and industry practice, is a structured and auditable link between corporate intent and project outcomes. Limited literature has been discovered which makes a link between corporate responsibility; project performance indicators (or critical success factors) and major infrastructure provision. This search revealed that a comprehensive mapping framework, from an organisation’s corporate objectives through to intended, anticipated and actual outcomes and impacts has not yet been developed for the delivery of such projects. The research problem thus explored is ‘the need to better identify, map and account for the outcomes, impacts and risks associated with economic, environmental, social and ethical outcomes and impacts which arise from major economic infrastructure projects, both now, and into the future’. The methodology being used to undertake this research is based on Checkland’s soft system methodology, engaging in action research on three collaborative case studies. A key outcome of this research is a value-mapping framework applicable to Australian public sector agencies. This is a decision-making methodology which will enable project teams responsible for delivering major projects, to better identify and align project objectives and impacts with stated corporate objectives.

15 year old volens to BMX riding risks

The Queensland Court of Appeal recently heard a case that raised the defence of volenti on fit injuria. By a majority of 2:1 the court held in Leyden v Caboolture Shire Council [2007] QCA 134 (20 April 2007) that the defence of volenti was established and defeated the action in negligence for damages for personal injury. The facts of the case were quite simple. The plaintiff was 15 years old when he was injured at the Bluebell Park which was controlled and managed by the Caboolture Shire Council (the defendant). The park had a BMX track – built and maintained by the defendant. At trial it was held that although the defendant owed a duty of care to entrants, a duty was not owed to the plaintiff. The judge found that the plaintiff was different to other entrants who used facilities provided by a council in a public park. The plaintiff was not relying upon the defendant to provide a BMX track with jumps that were reasonably safe as the evidence was that the track was regularly altered by third parties and the plaintiff knew that. Therefore it was reasoned that the plaintiff was relying upon the ability of the third parties who modified the jump and his own ability to use it, not the ability of the defendant to provide a reasonably safe track (at [10]). The trial judge also held that if a duty was owed, the defence of volenti applied so as to defeat the claim for damages. This was based upon the evidence that the plaintiff knew of the modification of the jump by third parties and knew of the risk. It was held that the plaintiff ‘had the appropriate subjective appreciation of the risk’ (at [11]).

Validity of the Waterlow screening tool and risks for pressure injury in acute care

Objectives: To assess the validity of the Waterlow screening tool in a cohort of internal medicine patients and to identify factors contributing to pressure injury. Design: Longitudinal cohort study Setting: A tertiary hospital in Brisbane, Australia Participants: 274 patients admitted through the Emergency Department or outpatient clinics and expected to remain in hospital for at least three days were included in the study. The mean age was 65.3 years. Interventions: Patients were screened on admission using the Waterlow screening tool. Every second day, their pressure ulcer status was monitored and recorded. Main outcome measures: Pressure ulcer incidence Results: Fifteen participants (5.5%) had an existing pressure ulcer and a further 12 (4.4%) developed a pressure ulcer during their hospital stay. Sensitivity of the Waterlow scale was 0.67, (95% CI: 0.35 to 0.88); specificity 0.79, (95% CI: 0.73 to 0.85); PPV 0.13, (95% CI: 0.07 to 0.24); NPV 0.98, (95% CI: 0.94 to 0.99). Conclusion: This study provides further evidence of the poor predictive validity of the Waterlow scale. A suitably powered randomised controlled trial is urgently needed to provide definitive evidence about the usefulness of the Waterlow scale compared with other screening tools and with clinical judgement.
