    The acceptable level of radiation risk for public members, that is 10/sup -5//y, was proposed by ICRP and other international organizations. We studied to survey basic procedures of deriving this value and to derive an acceptable risk value in Japan by using similar procedures. The basic procedures to derive 10/sup -5//y were found as follows; (1) 0.1 percent of annual mortality from all diseases, (2) 0.1 percent of life time risk, (3) one percent of mortality from all causes in each age cohort and (4) corresponding value to 1 mSv annual radiation exposure. From these bases we derived the value of 10/sup -5//y as acceptable risk level in Japan. The perception to risk level of 10/sup -5//y in conventional life was investigated by means of questionnaires for 1,095 college students living in Tokyo. The risks considered in this study were natural background radiation, coffee, skiing, X-ray diagnosis, spontaneous cancer, passive smoking and air pollution. The most acceptable risk was the risk related with natural background radiation. And the risk of natural background radiation was more easily accepted by the students who had knowledges on natural background radiation. On the other hand, the risk from air pollution or passive smoking was the most adverse one.

    The acceptable level of radiation risk for public members, that is 10 -5 /y, was proposed by ICRP and other international organizations. We studied to survey basic procedures of deriving this value and to derive an acceptable risk value in Japan by using similar procedures. The basic procedures to derive 10 -5 /y were found as follows; (1) 0.1 percent of annual mortality from all diseases, (2) 0.1 percent of life time risk, (3) one percent of mortality from all causes in each age cohort and (4) corresponding value to 1 mSv annual radiation exposure.

    Unmanned aircraft, or drones, are a rapidly emerging sector of the aviation industry. There has been limited substantive research, however, into the public perception and acceptance of drones. This article presents the results from two surveys of the Australian public designed to investigate (1) whether the public perceive drones to be riskier than existing manned aviation, (2) whether the terminology used to describe the technology influences public perception, and (3) what the broader concerns are that may influence public acceptance of the technology. We find that the Australian public currently hold a relatively neutral attitude toward drones. Respondents did not consider the technology to be overly unsafe, risky, beneficial, or threatening. Drones are largely viewed as being of comparable risk to that of existing manned aviation. Furthermore, terminology had a minimal effect on the perception of the risks or acceptability of the technology. The neutral response is likely due to a lack of knowledge about the technology, which was also identified as the most prevalent public concern as opposed to the risks associated with its use. Privacy, military use, and misuse (e.g., terrorism) were also significant public concerns. The results suggest that society is yet to form an opinion of drones. As public knowledge increases, the current position is likely to change. Industry communication and media coverage will likely influence the ultimate position adopted by the public, which can be difficult to change once established. © 2014 Society for Risk Analysis.

    Public acceptance of radioactive waste management alternatives depends in part on public perception of the associated risks. Three aspects of those perceived risks were explored in this study: (1) synthetic measures of risk perception based on judgments of probability and consequences; (2) acceptability of hypothetical radioactive waste policies, and (3) effects of human values on risk perception. Both the work on synthetic measures of risk perception and on the acceptability of hypothetical policies included investigations of three categories of risk: (1) Short-term public risk (affecting persons living when the wastes are created), (2) Long-term public risk (affecting persons living after the time the wastes were created), and (3) Occupational risk (affecting persons working with the radioactive wastes). The human values work related to public risk perception in general, across categories of persons affected

    Educational change, such as technology integration, involves risk. Teachers are encouraged to "take risks", but what risks they are asked to take and how do they perceive these risks? Developing an understanding of teachers' technology-related risk perceptions can help explain their choices and behaviours. This paper presents a way to…

    The concept of risk cannot be limited to simply knowing the probability of occurrence and the seriousness of the damages caused. It's a matter of social construction and numerous elements contribute towards its perception and acceptability. These elements have been studied for 20 years or so. Some of these elements influence risk perception such as awfulness, unfamiliarity, the number of people exposed to it, other elements influence its acceptance such as individual perceptions, social factors, ethics and equity. Their knowledge allows a better understanding of the evolution of perception and of the risk acceptability in general and transfusion risk in particular.

    This work establishes a methodology to evaluate the public acceptance of nuclear technology taking into consideration several risk concepts. Basic concepts of the nuclear science were transmitted, in form of lectures and courses, to the 13,439 Goiania residents, after the closing of the decontamination works, caused by the violation of the source of 137 Cs, of a teletherapy machine, in 1987. The results of the indicators shown that public's individuals perceive radiation risks and develop behaviors according to a constructive outline. The public does not know technical terms, being quite influenced by media, from where gets information of interest. The public orders the risks, relating them to accidents according to subjective criteria and models them as unknown, new and not observed at short period, establishing destruction, environmental catastrophe and diseases images.

    Full Text Available The determinants of the public's nuclear power acceptance have received considerable attention as decisive factors regarding nuclear power policy. However, the contingency of the relative importance of different determinants has been less explored. Building on the literature of psychological distance between the individual and the object, the present study demonstrates that the relative effects of different types of perceived risks regarding nuclear power generation differ across acceptance targets. Using a sample of Korea, our results show that, regarding national acceptance of nuclear power generation, perceived risk from nuclear power plants exerts a stronger negative effect than that from radioactive waste management; however, the latter exerts a stronger negative effect than the former on local acceptance of a nuclear power plant. This finding provides implications for efficient public communication strategy to raise nuclear power acceptance.

  14. Perceptions of industrial and nuclear risks. Stakes, negotiations and social development of levels of risk acceptance

    2007-11-01

    In this thesis we will question the perceptions of industrial risks in the occidental world at the beginning of the 21. century. For this purpose we will try to understand how concepts such as sustainable development, precautionary principle, liability, or even zero-risk bias have progressively developed around a thought model based on the scientific rationality. This model is now undermined by its incapacity to fully address the issues it raises and completely avoid the potential risks. However, despite consistent weaknesses, it remains a reference value moulded by past accidents which have led to the making of laws aiming mainly at defining liability and protecting those who are held liable. Thus, public information becomes a requirement for democracy and the protection of this thought model. In this context, the protagonists at stake are security-conscious, economical and political lobbies that constantly redefine the limits of risk acceptance. We come to the realization that our lifestyle and value system remain unchallenged even though undergoing a crisis. The specificity of this research lies into the importance we give to the local approach, dealing with registered Seveso sites and nuclear plants located in Indre et Loire. We have polled five categories of respondents through interviews or questionnaires in order to understand their opinion regarding situations involving technological risks. The result of this survey helps us understand and set the levels of risk acceptance that they define with regard to the industrial risks and show the complexity of a situation involving political stakes, environmental pressures, a profit-driven economy and security constraints, in a vague and complex context. This work gives us a contrasted picture of today's perceptions of risks. (author)

    This paper, based on the international research literatures on perception of risks, designs a conceptual model of public perception of nuclear power risk. In this model, it is considered that the public perception of nuclear power risk is a dynamic, complicate and closed system and is a process from subjective perception to objective risk. Based on the features of the public perception of nuclear power risk and multi-faceted dimension influences as discussed, suggestions for the public education for nuclear power acceptance are given in five aspects with indication that the public education for nuclear power acceptance plays an important role in maintaining the public perception of nuclear power risk system.

    Faced with a severe drought, the residents of the regional city of Toowoomba, in South East Queensland, Australia were asked to consider a potable wastewater reuse scheme to supplement drinking water supplies. As public risk perceptions and trust have been shown to be key factors in acceptance of potable reuse projects, this research developed and tested a social-psychological model of trust, risk perceptions and acceptance. Participants (N = 380) were surveyed a few weeks before a referendum was held in which residents voted against the controversial scheme. Analysis using structural equation modelling showed that the more community members perceived that the water authority used fair procedures (e.g., consulting with the community and providing accurate information), the greater their sense of shared identity with the water authority. Shared social identity in turn influenced trust via increased source credibility, that is, perceptions that the water authority is competent and has the community's interest at heart. The findings also support past research showing that higher levels of trust in the water authority were associated with lower perceptions of risk, which in turn were associated with higher levels of acceptance, and vice versa. The findings have a practical application for improving public acceptance of potable recycled water schemes. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The presented survey was conducted in six European countries as an online study. A total of 2454 subjects participated. Two main research questions were investigated: firstly, how does the cognitive, moral, and affective framing of radio frequency electromagnetic field (RF EMF) exposure perception influence RF EMF risk perception? Secondly, can the deployment of mobile phone base stations have greater acceptance with RF EMF exposure reduction? The findings with respect to the first question clearly indicated that the cognitive framed exposure perception is the main determinant of RF EMF risk perception. The concomitant sensitivity to exposure strength offers an opportunity to improve the acceptance of base stations by exposure reduction. A linear regression analysis supported this assumption: in a fictional test situation, exposure reduction improved the acceptance of base stations, operationalized as the requested distance of the base station from one's own home. Furthermore, subjects with high RF EMF risk perception were most sensitive to exposure reduction. On average, a 70% exposure reduction reduced the requested distance from about 2000 meters to 1000 meters. The consequences for risk communication are discussed.

  20. Differentiated influences of benefit and risk perceptions on nuclear power acceptance according to acceptance levels. Evidence from Korea

    2017-01-01

    The perceived benefit and risk of nuclear power generation have received considerable attention as determinants of the public's nuclear power acceptance. However, the contingency of the relative importance of these benefit and risk has been less explored. Using Korea as an example, this study explores the possibility that the relative importance of perceived benefit and risk on nuclear power acceptance depends on acceptance levels. Our results from latent class analysis and multinomial probit show that, in determining whether an individual shows a moderate level of nuclear power acceptance rather than a low level, perceived risk plays a dominant role compared to perceived benefit; however, regarding whether he/she shows a high level of nuclear power acceptance rather than a moderate level, this relative importance is reversed. These results carry practical implications for risk governance of nuclear power, particularly with regard to communication with the public. (author)

    Public response to risks of nuclear energy is investigated. A quantitative description of the attitudes, perceptions, and expectations of some members of the antinuclear public is given. Sample studies of the public at large were not made; most of the data in the paper comes from survey made at the University of Oregon and another with members of the Eugene, Oregon, League of Women Voters. Perceived risks and benefits, relative to other activities; risk characteristics; the reasons nuclear power is thought to be so dangerous; why death from nuclear power is thought to be so much worse than death from other causes; fatality estimates and disaster multipliers for 30 activities and technologies (alcoholic beverages, bicycles, commercial aviation, contraceptives, electric power, nuclear power, vaccinations, x-rays); fatality estimates associated with maximum credible disasters from commerical aviation and nuclear power are some of the areas covered in the surveys. The authors' view is that educational attempts designed to reduce the perception gap are probably doomed to failure, based on technical and psychological aspects of the problem. After discussing these issues, pathways toward acceptance of nuclear and nonnuclear energy systems are examined

    The present study analyzed people's risk perception regarding driving a car with studded or non-studded winter tires. Subjects were 252 residents of Sapporo, where a recent municipal ordinance prohibited studded tires, allowing only non-studded ones. Questionnaire data were examined concerning (1) the relationship between risk perception and its acceptance, (2) the effect of an inserted message, which was either positive or negative about the use of non-studded tires, and (3) the role of personal involvement, assessed with Personal Involvement Inventory (Zaichkowsky, 1985), regarding winter driving. Results were as follows: (1) The use of non-studded tires was favorably judged because of social benefit, but subjects hesitated to choose them because of a higher perceived possibility of an accident. (2) The inserted message had significant effects on benefit evaluation and perceived accident possibility. The effects were weaker for drivers who had experienced driving a car with studded tires. And (3) personal involvement had a weak correlation with risk judgements of the present study.

    Several alternative approaches to address the question open-quotes How safe is safe enough?close quotes are reviewed and an attempt is made to apply the reasoning behind these approaches to the issue of acceptability of radiation exposures received in space. The approaches to the issue of the acceptability of technological risk described here are primarily analytical, and are drawn from examples in the management of environmental health risks. These include risk-based approaches, in which specific quantitative risk targets determine the acceptability of an activity, and cost-benefit and decision analysis, which generally focus on the estimation and evaluation of risks, benefits and costs, in a framework that balances these factors against each other. These analytical methods tend by their quantitative nature to emphasize the magnitude of risks, costs and alternatives, and to downplay other factors, especially those that are not easily expressed in quantitative terms, that affect acceptance or rejection of risk. Such other factors include the issues of risk perceptions and how and by whom risk decisions are made

  4. Perception and acceptance of risk from radiation exposure in space flight

    There are a number of factors that influence how a person views a particular risk. These include whether the risk is judged to be voluntary and/or controllable, whether the effects are immediate or delayed, and the magnitude of the benefits that are to be gained as a result of being exposed to the risk. An important aspect of the last factor is whether those who suffer the risks are also those who stand to reap the benefits. The manner in which risk is viewed is also significantly influenced by the manner in which it is framed and presented. In short, risk does not exist in the world independent of our minds and cultures, waiting to be measured. Assessments of risk are based on models whose structure is subjective and associated evaluations are laden with assumptions whose inputs are dependent on judgments. In fact, subjectivity permeates every aspect of risk assessment. The assessment of radiation risks in space is no exception. The structuring of the problem includes judgments related to the probability, magnitude, and effects of the various types of radiation likely to be encountered and assumptions related to the quantitative relationship between dose and a range of specific effects, all of which have associated uncertainties. For these reasons, there is no magic formula that will lead us to a precise level of acceptable risk from exposure to radiation in space. Acceptable risk levels must evolve through a process of negotiation that integrates a large number of social, technical, and economic factors. In the end, a risk that is deemed to be acceptable will be the outgrowth of the weighing of risks and benefits and the selection of the option that appears to be best

    Aging in place is a preferred and cost-effective living option for older adults. Research indicates that technology can assist with this goal. Information on consumer preferences will help in technology development to assist older adults to age in place. The study aim was to explore the perceptions and preferences of older adults and their family members about a fall risk assessment system. Using a qualitative approach, this study examined the perceptions, attitudes, and preferences of 13 older adults and five family members about their experience living with the fall risk assessment system during five points in time. Themes emerged in relation to preferences and expectations about the technology and how it fits into daily routines. We were able to capture changes that occurred over time for older adult participants. Results indicated that there was acceptance of the technology as participants adapted to it. Two themes were present across the five points in time-safety and usefulness. Five stages of acceptance emerged from the data from preinstallation to 2 years postinstallation. Identified themes, stages of acceptance, and design and development considerations are discussed.

  7. Acceptance of new sanitation: The role of end-users' pro-environmental personal norms and risk and benefit perceptions.

    Current sanitation systems are inherently limited in their ability to address the new challenges for (waste)water management that arise from the rising demand to restore resource cycles. These challenges include removal of micropollutants, water (re)use, and nutrient recovery. New opportunities to address these challenges arise from new sanitation, a system innovation that combines elements of source separation, local treatment and reuse, and less use of water. New sanitation is applied, but not yet widespread, in several residential areas in Europe. Implementation is hindered by the lack of insight into the general public's willingness to engage in new sanitation, and the resulting uncertainty about this among decision makers and other stakeholders in wastewater management. Using value-belief-norm theory as a conceptual lens, this paper addresses the individual motivations (pro-environmental personal norms) and personal drivers (benefits) and barriers (risks) for acceptance of new sanitation by the Dutch general public. The results of an online survey (N = 338) indicated that both pro-environmental personal norms and risk and benefit perceptions predict consumers' willingness to accept new sanitation. More specifically, they showed that consumer acceptance is driven by perceived risks relating to the housing market and the need to change behavior, but also by environmental benefits. Overall, new sanitation was favorably evaluated by respondents: 64% indicated that they would likely use new sanitation if they were owner-occupiers. The results of this explorative study are discussed in light of the development of novel sanitation systems that are sensitive to perceptions of end-users and other key stakeholders.

  8. On risks and acceptability

    Watson, S.R.

    1981-01-01

    A very attractive notion is that it should be possible not only to determine how much risk is associated with any particular activity, but also to determine if that risk is acceptable. Stated boldly this seems an entirely unobjectionable and indeed a very acceptable notion. There is, however, underlying this idea, a mistaken view of risk which we might refer to as the ''phlogiston'' theory of risk. In this paper, presented at the SRP meeting on Ethical and Legal Aspects of Radiological Protection, the phlogiston theory of risk is described; secondly, it will be argued that it is too simple a theory to be realistic or useful; and thirdly, the management of risk will be placed in a wider decision framework. Acceptability, it will be argued is highly dependent on context, and it is not possible, therefore, to lay down generally applicable notions of acceptability. (author)

  9. PAGs - Public perception and acceptance

    Full text: While Protective Action Guides or PAGs have been a part of the lexicon of the radiation protection field for several decades, the concept of accepting higher levels of risk under certain situations has not received adequate scrutiny by the general public, the media or elected officials. Consequently there is a question as to how implementation of PAGs would be perceived by the above groups in the event that such implementation became necessary. A personal case in point involves the response of an executive in the food industry. When the concept of selling a food product meeting the PAGs was explained his response was, 'we won't sell a contaminated product, we would dump the unprocessed raw food. Our industry image is that of a natural unadulterated food'. While this may be an isolated view, there is a need to determine what is the perception and consequently what would be the response if PAGs were implemented today. If the response was negative by anyone of the three groups listed previously, then there is an obvious need for a program to assure receptiveness by those concerned. However, this may face formidable obstacles. This is because the terms radiation and radioactive have gained generally negative word associations, e.g. 'deadly' radiation and radioactive 'desert'. The former term was recently heard in a taped presentation at a Museum of Natural History on a completely unrelated subject. The latter term was part of a recent article heading in the Wall Street Journal. Incidentally the article was discussing television. Thus beyond the scientific issues of setting PAGs and the administrative and procedural issues of implementing PAGs there is the issue of society's understanding and acceptance of PAGs. Particularly, how can such understanding and acceptance be achieved in a situation which is associated with an actual or perceived radiation emergency? These are not questions that radiation or agricultural scientists can answer alone. These are

    Perceptions of risk from radiation have been studied systematically for about 20 years. This paper summarises the key findings and conclusions from this research with regard to the nature of risk perceptions, the impacts of these perceptions, and the need for communication about radiological hazards. Perhaps the most important generalisation from research in this area is that there is no uniform or consistent perception of radiation risks. Public perception and acceptance is determined by the context in which the radiation is used -and the very different reactions to different uses provide insight into the nature of perception and the determinants of acceptable risk.

    New drug and medical device introduction in Japan usually lags behind that in the West. Many reports indicate that in Japan, the associated risks are considered greater than the benefits recognized in other countries. This study aimed to compare the relationship between risk-benefit perception and acceptance of medical technologies in 3 leading markets. A tripartite cross-sectional survey of the general public was used. In total, 3345 adults in the United Kingdom, the United States, and Japan participated, and sexes and age groups were equally represented. Questions about the perception of risk, benefit, and acceptance of medical and other scientific technologies, and trust of medical product providers or regulatory authorities were included. Five-step Likert coding for risk/benefit/acceptance of 4 medical items (x-rays, antibiotics, vaccines, and cardiac pacemakers) and 6 general items (such as automobiles and airplanes) were collected. Relationships between benefit perception and acceptance were linear for 4 medical technologies. The relationship had a similar slope but was shifted downward in Japan compared with the UK and US ( P medical technologies, benefits of medical technologies, trust in doctors, and trust in the Department of Health. The UK and US attributes were clustered with positive responses such as "useful," "acceptable," and "trustworthy," whereas Japan was clustered with intermediate to negative responses such as "neither" and "untrustworthy." Acceptance of medical technologies was low in Japan because of significant differences in trust for doctors and authorities compared with that in the UK and US. This is a possible basis for delays of 24 to 60 months for medical product approval in Japan.

    Conclusion: Academic misconducts were mainly considered more acceptable than professional misconducts. Our results show that perceptions of acceptable conducts amongst optometry students are not very different from other students, and, against our initial prediction, do not show a general change in misconduct perception when students become more mature. Universities should pay more attention to this problem and take action.

    The perception of risks involves the process of collecting, selecting and interpreting signals about uncertain impacts of events, activities or technologies. In the natural sciences the term risk seems to be clearly defined, it means the probability distribution of adverse effects, but the everyday use of risk has different connotations (Renn, 2008). The two terms, hazards and risks, are often used interchangeably by the public. Knowledge, experience, values, attitudes and feelings all influence the thinking and judgement of people about the seriousness and acceptability of risks. Within the social sciences however the terminology of 'risk perception' has become the conventional standard (Slovic, 1987). The mental models and other psychological mechanisms which people use to judge risks (such as cognitive heuristics and risk images) are internalized through social and cultural learning and constantly moderated (reinforced, modified, amplified or attenuated) by media reports, peer influences and other communication processes (Morgan et al., 2001). Yet, a theory of risk perception that offers an integrative, as well as empirically valid, approach to understanding and explaining risk perception is still missing". To understand the perception of risk is necessary to consider several areas: social, psychological, cultural, and their interactions. Among the various research in an international context on the perception of natural hazards, it seemed promising the approach with the method of semantic differential (Osgood, C.E., Suci, G., & Tannenbaum, P. 1957, The measurement of meaning. Urbana, IL: University of Illinois Press). The test on seismic risk perception has been constructed by the method of the semantic differential. To compare opposite adjectives or terms has been used a Likert's scale to seven point. The test consists of an informative part and six sections respectively dedicated to: hazard; vulnerability (home and workplace); exposed value (with reference to

    Full Text Available The ubiquitous surfactants nonylphenol (NP and its ethoxylates (NPEOs, which are known as endocrine disrupters, have appeared in the lists of restricted chemical substances, monitoring programs, and environmental quality standards of many countries due to their adverse effects. Recent studies have reported alarming levels of NP, as the final metabolite of NPEOs, in Vietnamese urban waters, whilst response to this issue is negligible. With the aim of addressing how the public perceives and expects to avoid the risk of endocrine disrupting surfactants (EDSs, the study tested the hypothesized roles of specific knowledge, general knowledge, and perceived uncertainty using structural equation modelling. The findings revealed that different types of knowledge played certain roles in explaining risk perception, risk acceptability, and self-protective response, which are distinguished by experience amongst the public. Evidence of the mediating role that perceived uncertainty may play in the decrease of risk perception and the increase of risk unacceptance has been provided. The insights gained from the study may help answer why the public are in favor of taking non-diet-related self-protective measures rather than changing their dietary habits, which illustrates a comparison with the basis of health belief model. The needs for building cognitive capacity amongst the public, particularly pregnant women and young mothers, and risk communication concerning endocrine disrupting contamination linked to reproductive health are highlighted.

    Perception of risks by people depends on many factors, either characterizing the individuals, or specific to the risk sources. The risk concept, which confuses the issue, is precised first. Second, the perception phenomenon is presented as an interactive process involving the individual, the hazard, and the social context. Third, dimensions of perception are listed and used to describe the perception of radiation risks. Finally, the relation between perception and attitude is clarified. (author) 50 refs

    Public perceptions of risk will probably always be unsatisfying to a scientist. Public perceptions are formed by the actions of institutions which have goals other than formation of an informed public opinion, such as the schools, the media, business and the government. In this environment, it seems unrealistic to expect public opinion to reflect scientific realities. The talk will focus on the media as an opinion-former and will discuss several non-nuclear issues as illustrations: plague in New Mexico, Toxic Shock Syndrome, and Injuries as a Public Health Problem. Ultimately however, we are confronted with two wonderfully complex matters: can risk be adequately expressed or measured in universally comprehensible or broadly acceptable terms; and the mysterious movements of the public and collective mind

    To determine perceptions of acceptable conducts amongst under and postgraduate optometry students and to compare them with students from other disciplines. Students (under/postgraduate) of optometry (n=156) and other courses (n=54) from University of Minho participated in a voluntary online questionnaire about perception of conducts, classifying as acceptable or unacceptable 15 academic or professional scenarios. 210 questionnaires were analyzed. Differences in perceptions were found between optometry under and postgraduates in scenario 5, Chi-square(2,156)=4.3, p=0.038, and scenario 7, Chi-square(2,156)=7.0, p=0.008 (both with cheating more acceptable for postgrads). Differences between under and postgraduates from other courses were found in scenario 9 (taking supplies from classroom more acceptable for undergrads), Chi-square(1,54)=5.0, p=0.025, and scenario 14 (forging a signature more acceptable for postgrads), Chi-square(1,54)=3.9, p=0.046. Differences between optometry and other courses undergraduates were observed in scenario 2 (plagiarism more acceptable for optometry undergrads), Chi-square(1,154)=8.3, p=0.004 and scenario 9 (taking supplies from classroom more acceptable for other undergrads), chi-square(1,54)=7.8, p=0.005. Differences between optometry and other courses postgraduates were observed in scenario 7, Chi-square(1,56)=5.8, p=0.016, scenario 10 (both with cheating more acceptable for optometry postgrads), chi-square(1,54)=8.1, p=0.004 and scenario 14 (forging a signature more acceptable for other postgrads), Chi-square(1,54)=6.1, p=0.026.

    This four-stage study culminated in a game interface designed to calibrate people's perceptions of net risk (combining frequency and severity), in contexts where risks are elevated from their accepted, "typical" values, as when avalanche threats elevate the risks of "skiing" above levels skiers normally accept. Risk prompts are displayed dynamically, in naturalistic language, and not, for example, as static displays of dollar amounts or probabilities. Individual differences are measured. In Stage 1 (pilot), focus groups (n=9) piloted procedures, visual prompts, and examples of contexts where risks elevated from the "usual," for use in upcoming stages. In Stage 2 (exploratory), participants (primarily students; n=119; mean age, 20.1 years; 64 percent male) were assigned to risk contexts, answered demographic and risk-history questions, and then matched risk-description prompts to perceived "appropriate" levels along an ordinal risk scale. Descriptive measures and graphs showed response distributions; chi-squared analyses compared responses for different demographics. In Stage 3 (manipulating "cards"), participants (n=80; mean age, 37 years; 60 percent male) matched naturalistic risk prompts with ordinal risk positions. Regressions compared cards' placements with their "expected" (per exploratory Stage 2) placements. In Stage 4, the interface was coded in the Unity(®) (implemented at Business and IT Capstone, University of Ontario Institute of Technology, Oshawa, ON, Canada) development environment. In Stage 1, ambiguities in draft wordings/displays for Stage 2 were identified and corrected. Three risk contexts emerged: traffic/hidden intersection; skiing/avalanche; and swimming/drowning. In Stage 2, for traffic and skiing contexts, responses relating ordinal risk categories to realistic examples were observed to cluster around values potentially usable as markers. No associations appeared with demographic variables. In Stage 3, actual and "expected" ordinal-risk

    1995-01-01

    Most members of the public view the risks of nuclear power as uniquely hazardous. A survey in 1993 found that Canadians rank nuclear waste as the eleventh highest risk to their health. The trouble is that the public are not simply misinformed; rather, they view risk as something different from the product of probability of occurrence of an event multiplied by the measure of its harmful consequences. Among the 30 to 40 factors that influence public perception of risk, or acceptance of technology, are some that the scientific and technical community has hitherto failed to heed. Many of these factors can in fact be accommodated in the design, development and public presentation of nuclear projects. Such an accommodation of the public's views would involve dealing with factors like voluntariness, controllability, reversibility, equity and fairness, benefits, and trust in institutions. 9 refs

  20. Residential proximinity, perceived and acceptable risk

    Rogers, G.O.

    1984-01-01

    This paper focuses on the relationship between the life experiences associated with residential proximity, and the perception and acceptability of the risks associated with generating electricity in nuclear power plants. Perceived risk is operationally defined in terms of estimated likelihood of occurrence, while acceptability of nuclear power is defined in terms of people's favorable or unfavorable opinions regarding nuclear power plants. In the context of a simple social-structural model of perceived and acceptable risk, four potential explanations for enhanced acceptability among those residentially proximate with nuclear facilities are examined: residents, through the experience of living with hazard, are reinforced toward assigning lower probabilities to the potential risks associated with nuclear facilities; the cognitive dissonance created by the acceptance of the risks associated with nuclear power is decreased by reducing perceived risk; nuclear neighbors are predisposed toward, educated about, and/or economically dependent upon nuclear power hence the more favorable attitudes toward it; nearby residents are systematically more altruistic--other oriented--than the general population and thus more willing to bear the risks associated with nuclear power

This paper summarizes the major characteristics of three groups of technologists and four groups of the public which lead to many of the disagreements. To advance the mores of making decisions involving complex science or technology, technologists should develop an understanding of what information is needed for decisions, of the need for two-way communication with the public, and to become responsible for the accuracy and honesty of risk communication messages

    Examining those risk and benefit perceptions utilised in the formation of attitudes and opinions about emerging technologies such as nanotechnology can be useful for both industry and policy makers involved in their development, implementation and regulation. A broad range of different socio-psychological and affective factors may influence consumer responses to different applications of nanotechnology, including ethical concerns. A useful approach to identifying relevant consumer concerns and innovation priorities is to develop predictive constructs which can be used to differentiate applications of nanotechnology in a way which is meaningful to consumers. This requires elicitation of attitudinal constructs from consumers, rather than measuring attitudes assumed to be important by the researcher. Psychological factors influencing societal responses to 15 applications of nanotechnology drawn from different application areas (e.g. medicine, agriculture and environment, food, military, sports, and cosmetics) were identified using repertory grid method in conjunction with generalised Procrustes analysis. The results suggested that people differentiate nanotechnology applications based on the extent to which they perceive them to be beneficial, useful, necessary and important. The benefits may be offset by perceived risks focusing on fear and ethical concerns. Compared to an earlier expert study on societal acceptance of nanotechnology, consumers emphasised ethical issues compared to experts but had less concern regarding potential physical contact with the product and time to market introduction. Consumers envisaged fewer issues with several applications compared to experts, in particular food applications.

    Existing literature in people’s attitude toward nanotechnology and acceptance of nanotechnology applications has generally investigated the impact of factors at the individual or context levels. While this vast body of research is very informative, a comprehensive understanding of how attitude toward nanotechnology are formed and factors influencing the acceptance of nanotechnology are elusive. This paper proposes an exploratory nanotechnology perception-attitude-acceptance framework (Nano-PAAF) to build a systematic understanding of the phenomenon. The framework proposes that perceptions of risks and benefits of nanotechnology are influenced by cognitive, affective, and sociocultural factors. The sociodemographic factors of consumers and contextual factors mitigate the influence of cognitive, affective, and sociocultural factors on the perception of risks and benefits. The perceived risks and benefits in turn influence people’s attitude toward nanotechnology, which then influences acceptance of nanotechnology products. This framework will need further development over time to incorporate emerging knowledge and is expected to be useful for researchers, decision and policy makers, industry, and business entities.

    Various dimensions of risk are identified which relate to the manner in which risk is perceived and evaluated, and several self-consistent risk characteristics are explored. Factors which are thought to influence the perception of risk include the degree of personal control over the risk, the potential of episodic events, and the probable severity of injury if a risk event occurs. Risk-benefit analysis can be applied to three problems: the allocation of resources for safety expenditures, the setting of standards, and societal risk taking decisions. Calculations of benefit are needed for the third area of application, methods for the other two frequently do not require such a measure. (orig./RW) [de

    This paper presents recommendations of a subcommittee of the Westinghouse M ampersand 0 Nuclear Facility Safety Committee concerning toxic chemical risk acceptance criteria. Two sets of criteria have been developed, one for use in the hazard classification of facilities, and the second for use in comparing risks in DOE non-reactor nuclear facility Safety Analysis Reports. The Emergency Response Planning Guideline (ERPG) values are intended to provide estimates of concentration ranges for specific chemicals above which exposure would be expected to lead to adverse heath effects of increasing severity for ERPG-1, -2, and -3s. The subcommittee recommends that criteria for hazard class or risk range be based on ERPGs for all chemicals. Probability-based Incremental Cancer Risk (ICR) criteria are recommended for additional analyses of risks from all known or suspected human carcinogens. Criteria are given for both on-site and off-site exposure. The subcommittee also recommends that the 5-minute peak concentration be compared with the relevant criterion with no adjustment for exposure time. Since ERPGs are available for only a limited number of chemicals, the subcommittee has developed a proposed hierarchy of concentration limit parameters for the different criteria

Some are individual related (psychology, knowledge, experience), others describe the social environment (culture, ideology), others at end precise the nature of the risk. The word risk has various meanings and is understood differently by the three main categories involved in risk management, that is engineers, administrators and lay public. Several models which describe the perception phenomenon are presented. The dimensions affecting perception are listed. Based on public opinion poll data, a risk taxonomy is proposed, perceived nuclear risks are compared with other risks, and results are given concerning trust in the information diffused and the credibility of those in charge of nuclear activities.

    Acceptable risk studies involve uncertainties in future events: consequences and associated values, the acceptability levels, and the future decision environment. Probabilistic procedures afford the basic analytical tool to study the influence of each of these parameters on the acceptable risk decision, including their interrelationships, and combinations. A series of examples are presented in the paper in increasing complexity to illustrate the principles involved and to quantify the relationships to the acceptable risk decision. The basic objective of such studies is to broaden the scientific basis of acceptable risk decision making. It is shown that rationality and consistency in decision making is facilitated by such studies and that rather simple relationships exist in many situations of interest. The variation in criteria associated with an increase in the state of knowledge or change in the level of acceptability is also discussed

    Full Text Available OBJECTIVE: We aimed to investigate the ability of natalizumab (NTZ-treated patients to assume treatment-associated risks and the factors involved in such risk acceptance. METHODS: From a total of 185 patients, 114 patients on NTZ as of July 2011 carried out a comprehensive survey. We obtained disease severity perception scores, personality traits' scores, and risk-acceptance scores (RAS so that higher RAS indicated higher risk acceptance. We recorded JC virus status (JCV+/-, prior immunosuppression, NTZ treatment duration, and clinical characteristics. NTZ patients were split into subgroups (A-E, depending on their individual PML risk. Some 22 MS patients on first-line drugs (DMD acted as controls. RESULTS: No differences between treatment groups were observed in disease severity perception and personality traits. RAS were higher in NTZ than in DMD patients (p<0.01. Perception of the own disease as a more severe condition tended to predict higher RAS (p=0.07. Higher neuroticism scores predicted higher RAS in the NTZ group as a whole (p=0.04, and in high PML-risk subgroups (A-B (p=0.02. In low PML-risk subgroups (C-E, higher RAS were associated with a JCV+ status (p=0.01. Neither disability scores nor pre-treatment relapse rate predicted RAS in either group. CONCLUSIONS: Risk acceptance is a multifactorial phenomenon, which might be partly explained by an adaptive process, in light of the higher risk acceptance amongst NTZ-treated patients and, especially, amongst those who are JCV seropositive but still have low PML risk, but which seems also intimately related to personality traits.

    This paper seeks to consider social amplification as it applies to risk perception. Perceptions of the magnitude of a risk are conditioned by issues such as the degree of uncertainty in probability and consequences, the nature of the consequences and the relative weightings placed on probability and consequences. Risk perceptions are also influenced by factors such as confidence in the operator of an industrial process, trust in the regulator and the perceived fairness of regulatory decision-making. Different people may hold different views about these issues and there may also be difficulties in communication. The paper identifies and discusses self-reinforcing mechanisms, which will be labelled 'lock-in' here. They appear to apply in many situations where social amplification is observed. Historically, the term 'lock-in' has been applied mainly in the technological context but, in this paper, four types of lock-in are identified, namely scientific/technological, economic, social and institutional lock-in. One type of lock-in tends to lead to the next and all are buttressed by people's general acceptance of the familiar, fear of the unknown and resistance to change. The regulator seeks to make decisions which achieve the common good rather than supporting or perpetuating any set of vested interests. In this regard the locked-in positions of stakeholders, whether organisations, interest groups, or individual members of the public, are obstacles and challenges. Existing methods of consultation are unsatisfactory in terms of achieving a proper and productive level of dialogue with stakeholders

  3. Risk perception in planning

    The general public's perception of the risks involved with hazardous industries is increasing, especially in countries that high environmental amenity characteristics. This increased public awareness of risk may be an important factor in the future of countries who produce a large quantity of petroleum and chemical products. However, existing decision-making processes for determining safety controls do not take sufficient account of the community perception of risk. Identification of perceived risk levels could contribute to the determination of safe land-use planning policies and practices. The objective of land-use planning for hazardous industries is to reduce the gap between the calculated or technical assessment of risk and the risk as perceived by the community. This also facilitates a balanced approach in the decision making process between meeting industry requirements and community concerns. The comprehensive analysis presented in this study, based on a questionnaire given to residents in each of the three study areas (Australia, Japan and Korea), focused on identifying and measuring the respondent's understanding of the risk posed by nearby hazardous industrial developments.

    A survey on the perception in the Netherlands of 3 options to generate electricity, coal, uranium and wind, has been given. Special attention has been paid to the perception and acceptance of the risks of these options. The questionnaire has been constructed according to a modified Fishbein-model and was completed by 1112 respondents. Attention has been paid to the following questions: what is the distribution of attitudes towards the application of coal, uranium and wind; how are behavioral intentions determined by attitudes and normative influences; what is the relevance of factors like involvement with the subject, the perceived personal effectivity to influence collective decisions to use coal, uranium or wind, the level of information about these energy systems, the ways to obtain this information; are there people who feel threatened by the use of these energy systems; what are the preferences and expectations with respect to the use of energy options in the future; are there differences in risk perception between various population-categories. The presentation of empirical results is preceded by a review of recent literature on perception of (energy) risks and the report concludes with an elaborate discussion of the results and suggestions for energy policy and research.

    Acceptable-risk decisions are an essential step in the management of technological hazards. In many situations, they constitute the weak (or missing) link in the management process. The absence of an adequate decision-making methodology often produces indecision, inconsistency, and dissatisfaction. The result is neither good for hazard management nor good for society. This report offers a critical analysis of the viability of various approaches as guides to acceptable-risk decisions. This report seeks to define acceptable-risk decisions and to examine some frequently proposed, but inappropriate, solutions. 255 refs., 22 figs., 25 tabs.

    The objective of this paper is to investigate some of the implications inherent in the application of various proposed sets of risk acceptance criteria. A power-law model of risk aversion is utilized to estimate the equivalent number of individual deaths and is treated parametrically. The implications of ALARA requirements for cost-effective improvements are also illustrated. The risks assessed for various technological endeavors, as well as some estimated natural background risks, are compared to the trial criteria

    An implicit assumption of risk perception studies is that concerns expressed in questionnaires reflect concerns in everyday life. The aim of the present study is to check this assumption, i.e., the extrapolability of risk perceptions expressed in a survey, to risk perceptions in everyday life. To that end, risk perceptions were measured by a multidimensional approach. In addition to the traditional focus on measuring the magnitude of risk perceptions, the thematic relevance (how often people think about a risk issue) and the discursive relevance (how often people think about or discuss a risk issue) of risk perceptions were also collected. Taking into account this extended view of risk perception, an online survey was conducted in six European countries with 2454 respondents, referring to radio frequency electromagnetic field (RF EMF) risk potentials from base stations, and access points, such as WiFi routers and cell phones. The findings reveal that the present study's multidimensional approach to measuring risk perception provides a more differentiated understanding of RF EMF risk perception. High levels of concerns expressed in questionnaires do not automatically imply that these concerns are thematically relevant in everyday life. We use thematic relevance to distinguish between enduringly concerned (high concern according to both questionnaire and thematic relevance) and not enduringly concerned participants (high concern according to questionnaire but no thematic relevance). Furthermore, we provide data for the empirical value of this distinction: Compared to other participants, enduringly concerned subjects consider radio frequency electromagnetic field exposure to a greater extent as a moral and affective issue. They also see themselves as highly exposed to radio frequency electromagnetic fields. However, despite these differences, subjects with high levels of thematic relevance are nevertheless sensitive to exposure reduction as a means for improving the

    Social risk elicits self-esteem differences in signature social motivations and behaviors during the relationship-initiation process. In particular, the present research tested the hypothesis that lower self-esteem individuals' (LSEs) motivation to avoid rejection leads them to self-protectively underestimate acceptance from potential romantic partners, whereas higher self-esteem individuals' (HSEs) motivation to promote new relationships leads them to overestimate acceptance. The results of 5 experiments supported these predictions. Social risk increased activation of avoidance goals for LSEs on a word-recall task but increased activation of approach goals for HSEs, as evidenced by their increased use of likeable behaviors. Consistent with these patterns of goal activation, even though actual acceptance cues were held constant across all participants, social risk decreased the amount of acceptance that LSEs perceived from their interaction partner but increased the amount of acceptance that HSEs perceived from their interaction partner. It is important to note that such self-esteem differences in avoidance goals, approach behaviors, and perceptions of acceptance were completely eliminated when social risk was removed.

    The necessity for research and development of risk analysis methods arise from practical needs for safety for men and environment. Relating to speed of technological development risk is implemented in modern technological achievements. Complexity of approach to the concept of risk presents the essence of risk management. Risk management means to apply risk analysis in order to risk decrease and control. Database for risk management is in technical social, economic and political area. Risk perception is a construction in the field of social psychology i.e. public opinion research. These results are of importance for the risk management. Research presented in this paper has been done on the sample of 240 examines with two basic sub samples: person working with ionizing radiation (140 of them) and persons not working with ionizing radiation (100 of them). Attitudes to risk definition risk acceptance and relation to risk consequences. (author)

This paper presents a decision analytic approach to resolving some of those issues. A methodology for developing a radiological risk measure is presented, and several approaches to defining acceptable levels of that risk measure are considered. The methodology presented is oriented toward the development of radiological performance objectives for use as guidance in the drafting of regulations

    The risks of occupational exposure to radiation need fuller and more explicit characterization. They also need a more developed quantitative comparison with more familiar occupational hazards. To achieve this, some criterion is needed for establishing the amount of detriment one should attribute to different harmful effects, e.g., from accidents at work which cause death, temporary or permanent disability; from fatal and nonfatal cancers; from developmental abnormalities and any likely nonstochastic effects; and from a range of genetic defects. No such criterion for comparing incommensurable kinds of harm can be scientifically defined, but one is essential if occupational exposure standards are to be put into perspective. A comparison of the frequency of fatal cancers and severe genetic defects with that of accidental deaths at work is admittedly incomplete. One possible starting point is from a review of the average length of healthy life and activity lost as a result of nonfatal industrial accidents and some curable cancers, or of gross impairment during the course of an active disease or as a result of many types of genetic defect, or of life expectancy lost absolutely owing to fatal accidents and diseases. Estimates are discussed to emphasize the areas in which opinion is most needed to translate measures of risk based simply on total time lost into acceptable criteria of perceived detriment. Standards of industrial safety are reviewed on this basis, both for risk from accidents at work and from radiation exposure, with evidence on the rate at which both types of risk are being reduced

  18. Shoulder dystocia--malpractice or acceptable risk?

    Science.gov (United States)

    Skolbekken, J A

    2000-09-01

    In 1988 a new patient insurance system was introduced in Norway. It was initially described as an 'objectified' system, similar to one based on the no-fault principle. Early doubts were raised about the system's status, as it contains rules stating that compensation will not be given if the medical intervention is adequate and the involved risk is acceptable. This study was undertaken to examine the practice of these rules. An archival study was performed on the 41 shoulder dystocia cases that had been closed in the decade from 1988-1997. These cases were selected as shoulder dystocia was found to be the obstetrical event most often leading to a decision on acceptable risk. The most common injury in these cases was Erb's palsy, but fatalities and brain injuries were also observed. Compensation was given in nine cases, whereas it was denied due to an acceptable medical risk in the remaining cases. Indications of inconsistency among the reached decisions were found, and judged to be a result of differences of opinion between expert witnesses on the adequacy of the obstetrical practice. Doubts are raised as to whether similar decisions are reached in similar cases. Shoulder dystocia may be an acceptable risk in the sense that it is hard to predict and prevent. Whether the consequences of such a risk should be compensated, remains a political and economical issue. Present thinking leads to decisions that create a divide between the lucky unlucky and the plainly unlucky.

    Since 1984, a significant amount of media attention has focused on health threats from radon gas exposure. Using a probability telephone survey of adults (n = 685), we studied public perceptions of risk from radon exposure versus other environmental health risks. The results indicated that 92% of those individuals who had heard of radon believe radon to be a health risk, although only 4% believe they are currently exposed to high levels of radon gas. Perception of risk from radon was positively related to other perceptions of environmental risks. Younger and less educated individuals were more likely to perceive radon as a health risk. Women were three-and-one-half times as likely as men to perceive risk from radon. However, there was no significant relationship between perceived risk from radon and cigarette smoking. Media attention has apparently led to public awareness of radon hazards, but further attention is needed to improve smokers' awareness of their special risks from radon

    2001-01-01

    Acceptance of risk is a value-based decision, that is, the acceptance of risk by a person or group of persons depends on the values of the person or the shared values of the group. In the case of nuclear waste management, the nuclear industry, the regulators, and the general public approach risk from entirely different perspectives, dictated by the separate value systems held by each. The utilities producing radioactive waste view risk assessment as a part of a business decision that involves costs and benefits. The values that drive public acceptance of a national nuclear waste management policy are very different. As stated by Peter Montague of the Environmental Research Foundation: 'The only people I know who are enthusiastic about quantitative risk assessment are people who want to gain permission to expose other humans to dangerous chemicals so someone can make money. Risk assessment has proven to be an effective way to gain the necessary permissions'. Between the industry and the public are the regulators. Most national governments require regulatory agencies to establish rules that provide adequate public safety while allowing industries, whether nuclear or other producers of public commodities, to profitably do business. The general population has always had a fragile relationship with nuclear proponents. There is an atmosphere of mistrust based on the understanding that the values that matter to the general public differ tremendously from those purported by the industry and regulators. The general public is more interested in worst case scenarios; that is, what is the most severe negative consequence to their safety and the safety of their children that could result from nuclear projects. There is no cost or benefit more important to the general public than the health and safety of their families. The rift in values creates a great disparity in proposed solutions to the nuclear waste question. Regulators regard public acceptance of a risk-informed policy

    1989-09-01

    Full text: While Protective Action Guides or PAGs have been a part of the lexicon of the radiation protection field for several decades, the concept of accepting higher levels of risk under certain situations has not received adequate scrutiny by the general public, the media or elected officials. Consequently there is a question as to how implementation of PAGs would be perceived by the above groups in the event that such implementation became necessary. A personal case in point involves the response of an executive in the food industry. When the concept of selling a food product meeting the PAGs was explained his response was, 'we won't sell a contaminated product, we would dump the unprocessed raw food. Our industry image is that of a natural unadulterated food'. While this may be an isolated view, there is a need to determine what is the perception and consequently what would be the response if PAGs were implemented today. If the response was negative by anyone of the three groups listed previously, then there is an obvious need for a program to assure receptiveness by those concerned. However, this may face formidable obstacles. This is because the terms radiation and radioactive have gained generally negative word associations, e.g. 'deadly' radiation and radioactive 'desert'. The former term was recently heard in a taped presentation at a Museum of Natural History on a completely unrelated subject. The latter term was part of a recent article heading in the Wall Street Journal. Incidentally the article was discussing television. Thus beyond the scientific issues of setting PAGs and the administrative and procedural issues of implementing PAGs there is the issue of society's understanding and acceptance of PAGs. Particularly, how can such understanding and acceptance be achieved in a situation which is associated with an actual or perceived radiation emergency? These are not questions that radiation or agricultural scientists can answer alone. These are

    Risk perception has an important influence on wildlife management and is particularly relevant to issues that present health risks, such as those associated with wildlife disease management. Knowledge of risk perceptions is useful to wildlife health professionals in developing communication messages that enhance public understanding of wildlife disease risks and that aim to increase public support for disease management. To promote knowledge of public understanding of disease risks in the context of wildlife disease management, we used a self-administered questionnaire mailed to a stratified random sample (n = 901) across the continental United States to accomplish three objectives: 1) assess zoonotic disease risk perceptions; 2) identify sociodemographic and social psychologic factors underlying these risk perceptions; and 3) examine the relationship between risk perception and agreement with wildlife disease management practices. Diseases we assessed in the surveys were rabies, plague, and West Nile virus. Risk perception, as measured by an index consisting of severity, susceptibility, and dread, was greatest for rabies and West Nile virus disease (x = 2.62 and 2.59, respectively, on a scale of 1 to 4 and least for plague (x = 2.39). The four most important variables associated with disease risk perception were gender, education, prior exposure to the disease, and concern for health effects. We found that stronger risk perception was associated with greater agreement with wildlife disease management. We found particular concern for the vulnerability of wildlife to zoonotic disease and for protection of wildlife health, indicating that stakeholders may be receptive to messages emphasizing the potential harm to wildlife from disease and to messages promoting One Health (i.e., those that emphasize the interdependence of human, domestic animal, wildlife, and ecosystem health).

    This study was performed to evaluate consumers’ perception and acceptance of selected pork and chicken sausage (budim and chicken sausages, respectively) from Zlatiborac Meat Company. Sensory evaluation was performed by Serbian consumers (n=1157) in three retail stores in Belgrade. Consumers were asked for their preference for taste, salt content and smoke of two sausages and to recognize the kind of meat which was used to make these meat products. Consumers evaluated taste, salt content and smoke flavor of budim and chicken sausages with the highest percentage of the best offered answer. Between 47-55%, 72-76% and 82-84% of consumers evaluated the taste of sausages as good, the salt content as well-balanced and the smoke flavor as balanced, respectively. Tukey’s HSD test was applied to analyze variations of male and female perception and acceptance of analyzed sausages.

    Acceptable risk is defined in terms of its five basic parameters: the hazard or problem; the probability of occurrence; the consequence; the possible alternative actions; and the value system of the community or the society. The problem of consistency in design at a site and between differing sites is discussed and solutions are suggested. Techniques for consistent deterministic and probabilistic setting limits and design standards are illustrated using data from AEC Reactor Safety Study, WASH-1400. The influence of level of consequence is discussed and a general methodology for decision analysis in resource allocation problem is briefly introduced and illustrated. The concept of acceptable risk is put in a quantitative format that can be used by engineers and planners. Bayesian statistical methods are introduced to develop the methodologies

    2016-01-01

    Growing awareness of the potential for some energy-related activities to induce earthquakes has created a need to understand how the public evaluates the risks of induced earthquakes versus the benefits of energy development. To address this need, this study presents a web survey that used a between-subjects factorial experimental design to explore the views of 325 U.S. adults, who were asked about their experiences with earthquakes; risk perceptions related to different causes of earthquakes (e.g., natural versus induced); and acceptability of earthquakes depending on the benefits, beneficiaries, and decision making process. The results found that participants had more negative feelings toward induced versus naturally occurring earthquakes. Although they judged no earthquake as “acceptable,” participants rated induced earthquakes significantly less acceptable than naturally occurring ones. Attributing the benefits to the provision of renewable energy or climate change mitigation did not increase induced earthquake acceptability, and no particular beneficiary made earthquakes more acceptable, although private companies as beneficiaries made earthquakes less acceptable. Finally, induced earthquake acceptability was significantly higher when people believed that people like them had a voice in the decision to implement the technology that caused the earthquake, underscoring the importance of public engagement in the development of energy technologies. - Highlights: • Human induced earthquakes were perceived as more negative than natural earthquakes. • Attributing benefits to renewable energy did not increase earthquake acceptability. • Acceptability was highest after a procedurally fair decision making process. • Acceptability was lowest following an expert-driven decision.

Through empirical examples derived from our research and other studies, we show that fishermen’s risk perception can be explained...... by the need to adopt coping strategies, ie compromises and resilience in an environment marked by uncertainty and unpredictability. The difference between lay and expert knowledge is particularly salient in the case of safety researchers and fishermen. In order to make sense of the fishermen’s risk perception......In this paper we reflect on the possible reasons for the acceptability of risk in sea fishing and the implications they may have for safety actions and interventions. The data presented in the paper were collected during three trips at sea on fishing vessels in connection with a study of slips...

    Historically, human civilisations have striven to protect themselves against natural and man-made hazards. The degree of protection is a matter of political choice. Today this choice should be expressed in terms of risk and acceptable probability of failure to form the basis of the probabilistic design of the protection. It is additionally argued that the choice for a certain technology and the connected risk is made in a cost-benefit framework. The benefits and the costs including risk are weighed in the decision process. A set of rules for the evaluation of risk is proposed and tested in cases. The set of rules leads to technical advice in a question that has to be decided politically

  12. The Role of risk perception for risk management

    1999-01-01

    The list of individual and social factors that shape risk perception demonstrates that the intuitive understanding of risk is a multidimensional concept and cannot be reduced to the product of probabilities and consequences. Although risk perceptions differ considerably among social and cultural groups, the multi-dimensionality of risk and the integration of beliefs related to risk, the cause of risk, and its circumstances into a consistent belief system appear to be common characteristics of public risk perception in almost all countries in which such studies have been performed. Furthermore, the experience of risk is not limited to the threat of facing harm in the future. It includes subjective predictions of possible outcomes, the social and cultural context in which the risk is experienced, the mental images the risk situation evokes, the perception of the players who are involved in the risk situation and the judgments about fairness and equity related to the distribution of potential hazardous events. In this sense, risk is a social construct rather than a physical entity. Risk communication and conflict resolution is therefore a crucial element of any risk management strategy. The goal of risk communication and conflict resolution should not be to persuade people to accept whatever the communicator thinks is best for them. The ideal communication program envisions a receiver who processes all the available information to form a well-balanced judgement in accordance with the factual evidence, the arguments of all sides, and his/her own interests and preferences. The ultimate goal of risk communication is to reconcile expertise, interests, and public preferences. (EHS)

    Full Text Available BACKGROUND: How accurately do people perceive extreme wind speeds and how does that perception affect the perceived risk? Prior research on human-wind interaction has focused on comfort levels in urban settings or knock-down thresholds. No systematic experimental research has attempted to assess people's ability to estimate extreme wind speeds and perceptions of their associated risks. METHOD: We exposed 76 people to 10, 20, 30, 40, 50, and 60 mph (4.5, 8.9, 13.4, 17.9, 22.3, and 26.8 m/s winds in randomized orders and asked them to estimate wind speed and the corresponding risk they felt. RESULTS: Multilevel modeling showed that people were accurate at lower wind speeds but overestimated wind speeds at higher levels. Wind speed perceptions mediated the direct relationship between actual wind speeds and perceptions of risk (i.e., the greater the perceived wind speed, the greater the perceived risk. The number of tropical cyclones people had experienced moderated the strength of the actual-perceived wind speed relationship; consequently, mediation was stronger for people who had experienced fewer storms. CONCLUSION: These findings provide a clearer understanding of wind and risk perception, which can aid development of public policy solutions toward communicating the severity and risks associated with natural disasters.

  16. Risk perception in western Europe

    1999-01-01

    This paper describes empirical work on risk perception and some related dimensions, in particular with regard to radiation and nuclear power hazards. Most of the data cited come from a current CEC project in which 5 countries in Western Europe have participated. Models of risk perception are discussed and some generally valid findings concerning risk perception are summarized. Risk is seen to be a primary factor in many policy matters and clearly, to the public, more important than utility considerations. Previously formulated models (the Psychometric Model and Cultural Theory) are found to be deficient and a much more efficient alternative is suggested. It is stressed that risk perception is of interest foremost because it can be of value to decision makers in making difficult policy decisions in matters of risk. Hence, it is important to ask what facets of perceived risk are most strongly related to demand for risk mitigation. It is found that expected severity of consequences of an hazard is the clearly most important dimension. The paper concludes with a brief summary of a case study of Swedish experience with high-level nuclear waste repository siting

    Full text of publication follows: what is natural? And what is Nature? Are perceptions of Nature and naturalness related to perceptions of risk? This paper focuses on these aspects based on results from a Swedish representative sample (N=731), where subjects indicated e.g. the degree of naturalness of various phenomena, their views of nature, and personal life values, as well as perceptions of risk in specified contexts. The results showed a tendency to perceive as natural the phenomenon which is positively valued, i.e. what is natural is also good or desirable. Further, there were weak correlations between perceived naturalness and indicators of technological optimism, possibly indicating that persons with a more generous view of what is natural also more easily might accept change and outcomes due to human intelligence and activity. The construct of 'tampering with nature' has previously been shown to be one good predictor of perceived risk. The respondents also rated their agreement with items aimed to reflect the four 'views of nature' as suggested by Cultural Theory, i.e. nature as robust, capricious, tolerant and fragile. Nature was foremost perceived as fragile, but the main result clearly revealed that peoples' views of nature were complex and most often involved several of the suggested categories. The discussion focuses on the possible implications on environmental concern and risk perception given that Nature would develop into an undesirable type of locality. (author)

    1977-01-01

    Living in a technological society with large energy requirements involves a number of related actities with attendant health risks, both to the working and to the general public. Therefore, the formulation of some general principles for risk acceptance is necessary. In addition to maximizing benefits and minimizing risk, relevant considerations must be made about the perception of risk as voluntary or involuntary, the number of persons collectively at risk at any one occasion, and the extent to which a risk is a familiar one. With regard to a given benefit, such as a given amount of energy, comparisons of the risks of alternate modes of production may be utilized. However, cost-benefit consideration is essential to the amelioration of current or prospective risks. This is unusual, since it is based on some estimate of the monetary value per premature death averted. It is proposed that increased longevity would be a more satisfactory measure. On a societal basis, large expenditures for additional energy-related pollution control do not appear justifiable since much larger, nonenergy-related health risks are relatively underaddressed. Knowledgeable health professionals could benefit the public by imparting authoritative information in this area

  20. Some thoughts on risk acceptance and nuclear power

    Brejora, S.

    2001-01-01

    Risks are assessed very differently in our modern society. While a number of everyday risks, some of which are hardly perceptible while others are quite spectacular, are accepted to a considerable extent, many other risks, often minor ones, are overemphasized and rejected. Risk assessment in the minds of people is a function of a number of subjective, emotional factors with decisive psychological components which lead to irrational assessment especially of a number of manmade risks, including nuclear power. Factors to be mentioned in the assessment of the risks of nuclear power, among others, are the imaginary phenomenon of radioactivity and nuclear fission; the growing intrusion of technology into our living environment; the need to fall back upon expert knowledge; and the intuitive, wrong correlation of technical expense for safety with the perceived risk. As is seen, opinions are formed not solely on the basis of rational findings, but are influenced by many factors, some of which cannot be reproduced in a rational way. This makes it imperative to include in the debate about risks of technology, specifically the discussion about the use of nuclear power, the psychological aspect in order to arrive at a reasonable way for society to handle technology.

    The initial phase of the work performed during FY 1977 consisted of performing a ''scoping'' study to define issues, determine an optimal methodology for their resolution, and compile a data base for acceptable risk criteria development. The issues, spanning technical, psychological, and ethical dimensions, were categorized in seven major areas: (1) unplanned or accidental events, (2) present vs future risks, (3) institutional controls and retrievability, (4) dose-response mechanism and uncertainty, (5) spatial distribution of exposed populations, (6) different types of nuclear wastes, and (7) public perception. The optimum methodology for developing ARC was determined to be multi-attribute decision analysis encompassing numerous specific techniques for choosing, from among several alternatives, the optimal course of action when the alternatives are constrained to meet specified attributes. The data base developed during the study comprises existing regulations and guidelines, maximum permissible dose, natural geologic hazards, nonradioactive hazardous waste practices, bioethical perspectives, and data from an opinion survey

    A recent two-day meeting was called by the Royal Society to discuss all types of risks, but symptomatic of the concerns of most of those present, the discussion centred mainly on the risks inherent in energy production and use. Among the subjects considered were public perception of differing risks, and how these are ranked, and risks versus benefits. Quotations from and summaries of many of the papers presented show that it was generally felt that scientists must be very careful in the way that they use numerical assessments of risk and that they should pay more attention than they have to social and political factors.

  4. Accepted monitoring or endured quarantine? Ebola contacts' perceptions in Senegal.

    During the 2014-2016 West Africa Ebola epidemic, transmission chains were controlled through contact tracing, i.e., identification and follow-up of people exposed to Ebola cases. WHO recommendations for daily check-ups of physical symptoms with social distancing for 21 days were unevenly applied and sometimes interpreted as quarantine. Criticisms arose regarding the use of coercion and questioned contact tracing on ethical grounds. This article aims to analyze contact cases' perceptions and acceptance of contact monitoring at the field level. In Senegal, an imported case of Ebola virus disease in September 2014 resulted in placing 74 contact cases in home containment with daily visits by volunteers. An ethnographic study based on in-depth interviews with all stakeholders performed in September-October 2014 showed four main perceptions of monitoring: a biosecurity preventive measure, suspension of professional activity, stigma attached to Ebola, and a social obligation. Contacts demonstrated diverse attitudes. Initially, most contacts agreed to comply because they feared being infected. They adhered to the national Ebola response measures and appreciated the empathy shown by volunteers. Later, acceptance was improved by the provision of moral, economic, and social support, and by the final lack of any new contamination. But it was limited by the socio-economic impact on fulfilling basic needs, the fear of being infected, how contacts' family members interpreted monitoring, conflation of contacts as Ebola cases, and challenging the rationale for containment. Acceptance was also related to individual aspects, such as the professional status of women and health workers who had been exposed, and contextual aspects, such as the media's role in the social production of stigma. Ethnographic results show that, even when contacts adhere rather than comply to containment through coercion, contact monitoring raises several ethical issues. These insights should contribute to

    There has lately been a greater responsivement in the media as well as the general public to the risk potential of high-frequency electromagnetic fields (EMF). If the discussion continues to gain momentum, this could have grave consequences for companies offering the products or services under attack. The working group Man, Environment, Technology (MUT) at Juelich Research Centre has examined the question of how EMF risks are valuated by the public. The study centered on the following questions: How are EMF risk potentials perceived by the public and what factors influence the public discussion? What future course might the discussion on risks take and what critical events and conditions deserve particular attention? The authors present and discuss the results of this first German study on product-inherent risks. (orig.) [de

  6. An approach to societal risk acceptance criteria and risk management

    Okrent, D.; Whipple, C.

    1977-06-01

    A quantitative approach to risk acceptance criteria and risk management is proposed for activities involving risk to individuals not receiving direct benefits, such as employment, from the activity. Societal activities are divided into major facilities or technologies, all or part of which are categorized as essential, beneficial, or peripheral, and a decreasing level of acceptable risk to the most exposed individual is proposed (say, 0.0002/year for essential, 0.00001/year for beneficial, and 0.000002/year for peripheral activity). The risk would be assessed at a high confidence level (say, 90%), thereby providing an incentive to the gaining of better knowledge. Each risk-producing facility, technology, etc., would have to undergo assessment both of risk to the individual and to society. The cost of the latter would have to be internalized, probably via a tax paid to the Federal Government, which in turn would redistribute the benefit as national health insurance or reduced taxes to the individual. Risk aversion to large events would be built into the internalization of the cost of risk

    The aim of the study was to determine the acceptance and perception of Nigerian patients to medical photography. A self-administered questionnaire was distributed among Nigerian patients attending oral and maxillofacial surgery and plastic surgery clinics of 3 tertiary health institutions. Information requested included patients' opinion about consent process, capturing equipment, distribution and accessibility of medical photographs. The use of non-identifiable medical photographs was more acceptable than identifiable to respondents for all purposes (P = 0.003). Most respondents were favourably disposed to photographs being taken for inclusion in the case note, but opposed to identifiable photographs being used for other purposes most especially in medical websites and medical journals. Female respondents preferred non-identifiable medical photographs to identifiable ones (P = 0.001). Most respondents (78%) indicated that their consent be sought for each of the outline needs for medical photography. Half of the respondents indicated that identifiable photographs may have a negative effect on their persons; and the most commonly mentioned effects were social stigmatization, bad publicity and emotional/psychological effects. Most of the respondents preferred the use of hospital-owned camera to personal camera/personal camera-phone for their medical photographs. Most respondents (67.8%) indicated that they would like to be informed about the use of their photographs on every occasion, and 74% indicated that they would like to be informed of the specific journal in which their medical photographs are to be published. In conclusion, non-identifiable rather than identifiable medical photography is acceptable to most patients in the studied Nigerian environment. The use of personal camera/personal camera-phone should be discouraged as its acceptance by respondents is very low. Judicious use of medical photography is therefore advocated to avoid breach of principle of

    The fact that the risks deriving from different activities involving the same radiation exposure are seen very differently by a single population is a highly significant one. Exactly identical risks are considered oppositely, depending on the origin of radiation (whether produced by medical applications or by nuclear power plants, resulting from natural radiation or from artificial radiation). It appears as if there was good radiation and bad radiation..! One of the purposes of the paper is the discussion of causes. The acceptance of a given risk by a certain section of the population is closely related to the benefits that the group expects to receive-either consciously or unconsciously-from the activity producing the risk. Consequently, an analysis of the factors influencing the eventual rejection of a practice should explore not only fears, but also hopes...! On the basis of a risk-perception survey carried out in a population sector attending hospitals-including both patients and physicians-, a prior objective analysis of the results obtained was performed and, later on, the various statements by those surveyed were studied. The design of the survey allowed for a comparative assessment of the perception of different risks depending on the people's educational and social level. An epistemological study was made on the validity involved in the use of the data resulting from the survey, so as to reach different conclusions. The population's opinion about the capacity for response, the qualification and the mitigation means available to the State authorities in order to face an eventual radiological emergency plays a leading role in risk perception. In an analysis of the relevant factors involved in risk and benefits perception by the population (in the real world), attention must be paid to the existence of organized opinion groups representing the interest of a given sector. Of course, the population's confidence in the experts providing the information is a key

    A seismic event generally has consequences on the social relationships, economy and culture of the impacted territory. As Mary Douglas quotes, a change into the social perception of risk as consequence of an earthquake may have effects on the lifestyle of the local community. The above mentioned statement is the starting point of this article. illustrating the difference between peril and risk is the second point. According to the Aristotelian theory of categories, risk can be considered as a human characteristic depending on social and cultural factors. Risk is here intended as a social category and cannot be de facto reported as a statistical or stochastic function based on a mathematical formula, as long assumed in the past. This approach, then, requires a deep revision. In this sense, and following the concept of risk perception, seismic risk is analysed in this article in terms of impacts, precautionary measures, risk assessment and management. Knowledge of this topic cannot be intended as a simple philosophical exercise, since right on awareness depend risk reduction, humans and goods too [it

  10. The role of risk perception for risk management

    Renn, Ortwin

    1998-01-01

    Are risks social constructions of different societal actors that can be checked at best against standards of consistency, cohesion and internal conventions of deduction, but cannot claim any validity outside of the actor's logical framework? Or are technical estimates of risk representations of real hazards that can and will affect people as predicted by the statistical values, regardless of the beliefs or convictions of those who conduct the assessments? Which of the two sides one takes determines the legitimate function of risk perception for management purposes. The paper argues that both extremes, the constructivist and the realist perspective, miss the point, as risks are always mental representations of threats that are capable of claiming real losses. Over the last two decades, risk analysts have dealt with both sides of risk in an additive fashion. In times in which risk management has been under serious pressure to demonstrate effectiveness and cost-efficiency, the parallel approach of pleasing the technical elite and the public alike has lost legitimacy. In order to integrate risk assessment and perception, the paper analyses the strengths and weaknesses of each approach to risk analysis and highlights the potential contributions that the technical sciences and the social sciences can offer to risk management. Technical assessments provide the best estimate for judging the average probability of an adverse effect linked to an object or activity. First, public perception should govern the selection of criteria on which acceptability or tolerability are to be judged. Second, public input is needed to determine the trade-offs between criteria. Third, public preferences are needed to design resilient strategies for coping with remaining uncertainties. A public participation model is introduced that promises an integration of analytic knowledge and deliberative process involving those who will be affected by the respective risk

    The objective of this study was to develop a methodology for determining the acceptable levels of risk with respect to nuclear energy. It was concluded that the Atomic Energy Control Board should identify the interest groups that affect its choice of an acceptable level of risk, determine their expectations, and balance the expectations of the various groups such that the resulting acceptable level of risk is still acceptable to the Board. This would be done by interviewing experts on the subject of nuclear safety, developing and pretesting a public questionnaire, and surveying the public on acceptable cost-risk combinations

    2008-04-01

    Full Text Available We compare and critique two measures of risk perception. We suggest that a single question --- ``How risky is the situation?'' --- captures the concept of risk perception more accurately than the multiple-item measure used by Sitkin and Weingart (1995. In fact, this latter measure inadvertently captures notions of attractiveness or expected return, rather than risk perception. We further propose that the error underlying the construction of Sitkin and Weingart's measure is explained in terms of a top-down model of risk perception, in which perceived risk and perceived return are consequences, rather than determinants, of attractiveness. Two studies compare the validity of the two alternative measures.

    Experts and the public frequently disagree when it comes to risk assessment. The reasons for such disagreement are discussed, and it is pointed out that disagreement among experts and lack of full understanding of real risks contributes to skepticism among the public. The notion that people are in general reacting in a highly emotional and non-rational, phobic, manner is rejected. The very conditions for risk assessment present to the public, and common-sense cognitive dynamics, are better explanations of risk perception, as are some social psychological concepts. If trust is to be established in a country where it is quite low some kind of politically regulated public influence on decision making and risk monitoring is probably needed, e.g. by means of a publicly elected and responsible ombudsman. 57 refs, 8 figs, 5 tabs.

    In insurance science and natural science risks are defined as the expected extent of damages per time unit, i.e. risks are determined by empirical data representing the average number of people who incur damages in one year or one decade. In the social sciences the concept of risk is understood as the paragon of all unforeseeable consequences of an event or an action, or even plainly as the sum of things threatening our life and environment. Of course, the intuitive understanding of the concept is also of interest: what do people consider risky, how do they assess risks and how do they cope with risky situations. It is a chief task of interdisciplinary research to investigate the tension between the scientific and intuitive perception of risks and to develop political recommendations for those responsible for decision-making.

  17. Safety analysis, risk assessment, and risk acceptance criteria

    International Nuclear Information System (INIS)

    Jamali, K.

    1997-01-01

    This paper discusses a number of topics that relate safety analysis as documented in the Department of Energy (DOE) safety analysis reports (SARs), probabilistic risk assessments (PRA) as characterized primarily in the context of the techniques that have assumed some level of formality in commercial nuclear power plant applications, and risk acceptance criteria as an outgrowth of PRA applications. DOE SARs of interest are those that are prepared for DOE facilities under DOE Order 5480.23 and the implementing guidance in DOE STD-3009-94. It must be noted that the primary area of application for DOE STD-3009 is existing DOE facilities and that certain modifications of the STD-3009 approach are necessary in SARs for new facilities. Moreover, it is the hazard analysis (HA) and accident analysis (AA) portions of these SARs that are relevant to the present discussions. Although PRAs can be qualitative in nature, PRA as used in this paper refers more generally to all quantitative risk assessments and their underlying methods. HA as used in this paper refers more generally to all qualitative risk assessments and their underlying methods that have been in use in hazardous facilities other than nuclear power plants. This discussion includes both quantitative and qualitative risk assessment methods. PRA has been used, improved, developed, and refined since the Reactor Safety Study (WASH-1400) was published in 1975 by the Nuclear Regulatory Commission (NRC). Much debate has ensued since WASH-1400 on exactly what the role of PRA should be in plant design, reactor licensing, 'ensuring' plant and process safety, and a large number of other decisions that must be made for potentially hazardous activities. Of particular interest in this area is whether the risks quantified using PRA should be compared with numerical risk acceptance criteria (RACs) to determine whether a facility is 'safe.' Use of RACs requires quantitative estimates of consequence frequency and magnitude

    Acceptance criteria applied in practical risk analysis are recapitulated including the concept of rist profile. Modelling of risk profiles is illustrated on the basis of compound Poisson process models. The current practice of authoritative acceptance criteria formulation is discussed from...... a decision theoretical point of view. It is argued that the phenomenon of risk aversion rather than being of concern to the authority should be of concern to the owner. Finally it is discussed whether there is an ethical problem when formally capitalising human lives with a positive interest rate. Keywords......: Risk acceptance, Risk profile, Compound Poisson model for risk profile, Capitalization of human life, Risk aversion....

    Along with the progressive acceleration of urbanization, the need to identify potentially troublesome "Not In My Back Yard" (NIMBY) facilities in the city is inevitable. To resolve NIMBY conflict, it is important to know people's NIMBY risk acceptability for these facilities. A questionnaire survey was used among Chinese and Japanese college students to identify NIMBY risk acceptability. LISREL was used to construct a structural equation model to analyze the difference in NIMBY risk acceptability between the Chinese and Japanese college students. Factors that may affect NIMBY risk acceptability were analyzed: "perceiving utility," "perceiving risk," "trust in government," "reasonable compensation," and "procedural justice." The findings show that Japanese students' concerns were greater than Chinese students' concerns. Perceiving utility and perceiving risk were the most important factors that affect people's NIMBY risk acceptability, followed by procedural justice, trust in government, and reasonable compensation. There is a difference between the different cultural backgrounds in confronting the risk: Chinese students focus more on the reputation and value of real estate, while Japanese students pay more attention to environmental pollution and damage to health. Furthermore, cultural influences play a role in students' risk perception. To improve the risk acceptability for NIMBY facilities and provide a basis for resolving NIMBY conflicts, it is necessary to ensure the benefits of the NIMBY facility while reducing environmental pollution. The findings of this study may be of interest for policy makers and practitioners to devise future NIMBY strategies.

    The recognition of the societal dimension of risk assessment has been at the cradle of the opinion research on risks. Since risk estimates are not fixed by experts anymore, but are considered to show variation across a diverse population, the people themselves must be asked how they experience the risks. Following the rise in popularity of risk assessment and the recognition of its 'human' dimension, the demand for public opinion surveys on risks has been increasing at a fast pace. Unfortunately, this high demand sees some negative consequences. First, surveys are frequently conducted by people lacking even a minimal knowledge of survey methodology. In this respect, we might think of a journal or a newspaper trying to impress their readers with the definitive public opinion poll about the latest issue in vogue. Second, time pressure causes experienced or trained researchers to lower themselves to 'quick and dirty' work. While methodologically flawed opinion research might not be something to worry about when appearing in the amusement press, concern is due if the results of a survey inspire policy development. Indeed, when public opinion research is conceived as an instrument to support rational, evidence based public policy, the strictest methodological standards should be applied, even if it is clear that scientific research will never substitute political reasoning. This contribution deals with the safeguarding and enhancing of the quality of large scale surveys focusing on risk perception and related issues. This attention is relevant, not only for the reason that methodological standards may be flawed due to the immense popularity of the opinion poll, but also because the results of opinion surveys may have far-reaching policy consequences.

    Full Text Available The presented study is part of the EU Project LEXNET (Low EMF Exposure Future Networks, which deals among other things with the issue of whether a reduction of the radiofrequency (RF electro-magnetic fields (EMF exposure will result in more acceptance of wireless communication networks in the public sphere.We assume that the effects of any reduction of EMF exposure will depend on the subjective link between exposure perception and risk perception. Therefore we evaluated respondents’ risk perceptions of different RF EMF sources and their subjective knowledge about various exposure characteristics with regard to their impact on potential health risks. The results show that participants are more concerned about base stations than about all other RF EMF sources. Concerning the subjective exposure knowledge the results suggest that people have a quite appropriate impact model. The question how RF EMF risk perception is actually affected by the knowledge about the various exposure characteristics was tested in a linear regression analysis. The regression indicates that these features - except distance - do influence people’s general RF EMF risk perceptions. In addition, we analyzed the effect of the quality of exposure knowledge on RF EMF risk perception of various sources. The results show a tendency that better exposure knowledge leads to higher risk perception, especially for mobile phones. The study provides empirical support for models of the relationships between exposure perception and risk perception. It is not the aim to extrapolate these findings to the whole population because the samples are not exactly representative for the general public in the participating countries.

    Industry can master risks but it cannot master the representations people have of these risks. This is why distortions may occur, as the public perceives risks where they are not, or in a totally deformed way. To deal with this type of situation which is dangerous in the long run, both for society and industry, it is necessary to study in detail where and how the difference between real risks and perceived risks is introduced. It then becomes possible to determine what means of action are available to manage the representations and the perceptions of risks. We shall mention two rather different examples of type of direct contact with the industrial reality; in France, we have determined policy of visits of nuclear sites (more than 10 000 people visit Cogema- la Hague site yearly), mainly addressed to school children and people living in the vicinity of the site. During these visits there is of course no question of explaining the detailed operation of the facility or the risks it generates. The purpose is to make the representation of the nuclear industry just as familiar as the representation of another large-scale technology tool: trains, dams,. In a different manner, missions are organised by Cogema - B.N.F.L.- O.R.C. (Overseas reprocessing Committee) to de dramatize the transport of high level vitrified wastes from Europe to Japan. these missions travel through those countries the ship come close to. Here, again, although the target is more the relays of opinion, the effective presence of specialized transport ship is a crucial element in putting a halt to phantasmic representations, as they are born from the remoteness of the object.

    Young people are spending increasing amounts of time using digital technology and, as such, are at great risk of being involved in cyber bullying as a victim, bully, or bully/victim. Despite cyber bullying typically occurring outside the school environment, the impact of being involved in cyber bullying is likely to spill over to school. Fully 285 11- to 15-year-olds (125 male and 160 female, M age  = 12.19 years, SD  = 1.03) completed measures of cyber bullying involvement, self-esteem, trust, perceived peer acceptance, and perceptions of the value of learning and the importance of school. For young women, involvement in cyber bullying as a victim, bully, or bully/victim negatively predicted perceptions of learning and school, and perceived peer acceptance mediated this relationship. The results indicated that involvement in cyber bullying negatively predicted perceived peer acceptance which, in turn, positively predicted perceptions of learning and school. For young men, fulfilling the bully/victim role negatively predicted perceptions of learning and school. Consequently, for young women in particular, involvement in cyber bullying spills over to impact perceptions of learning. The findings of the current study highlight how stressors external to the school environment can adversely impact young women's perceptions of school and also have implications for the development of interventions designed to ameliorate the effects of cyber bullying.

    China's nuclear industry is recently experiencing rapid development, creating a need for research into public perceptions and acceptance of nuclear power. In this paper, we propose a strategy for investigating public perception and acceptance in China, in a continuous and accurate way, and testing the effectiveness of public education in order to find a proper way to improve the perception and acceptance of nuclear energy in China. Questionnaires are conducted separately both before and after public education activities on nuclear energy held in Beijing. Some conclusions and future continuation of this study are also discussed.

    1991-12-01

    The relationship between acceptability of risk and moral valuation of risky activities was investigated in children, 10-16 years old. It was found that all age groups exhibited a strong correlation between the two dimensions of risky activities. Older children were more tolerant of risk taking than younger children. Individual actions were judged in a more lenient manner than collective actions. Girls tended to be more morally condemning towards risk taking, but the youngest girls were not less prone to accept risks than boys. General measures of moral development according to Piaget and Kohlberg were not associated with perceived acceptability of risk or the judged morality of risky activities but relations were found between risk taking and assertiveness and perceived freedom, which were the most important factors in accounting for risk and morality attitudes. 22 refs, 9 figs, 4 tabs

    This paper reviews the approach taken to assess the social impacts of the proposed high-level nuclear waste repository at Yucca Mountain, Nevada on residents in the closest metropolitan area, Las Vegas. The purpose of this portion of the assessment is to investigate the effects of the repository on the future well-being and behavior of Las Vegas residents under different operational futures of the repository. To investigate these effects, a research design and conceptual framework were developed to collect data from a random sample of Las Vegas metropolitan area residents. The design allows for the collection of both baseline data (to determine current risk perceptions and behaviors) and projected effects of the repository under four different operational futures

    Eiser, J.R.

    1989-01-01

    Much research on acceptance of risks implies a distinction between objective and subjective definitions of risk. This paper disputes this distinction, arguing instead that discrepancies between public and 'expert' views are to be better understood in terms of differences in how decisions are seen to be made. Risk is a product of decisions taken in response to environmental events, and depends not simply on the threat posed by such events but on the quality of the decisions. A model of decision quality is presented, derived from signal detection theory, which distinguishes between the ability to discriminate between different kinds of events, and the criterion, or level of certainty that is required before a particular response is chosen. Whereas discrimination ability depends on the expertise of decision-makers and the predictability of the events in question, the response criterion reflects considerations of costs, benefits and equity. Where the cost of overlooking a real threat ('false-negative' response) is high, a cautious criterion may be demanded. Where discrimination ability is also seen to be low, the chance of 'false-negatives' may only be adequately reduced at the price of a large number of 'false-positives', or 'unnecessary' protective responses against imagined threats. In extreme cases, this may amount to total opposition to the operation of a system. (author)

    The report describes the methodology and the results of a study of public attitudes towards five energy sources: nuclear power, hydro power, solar energy, oil and geothermal energy. The analysis is based on a survey carried out in the Metro Manila area in the Philippines. The samples consist of Barangay Leaders (192 respondents), Science teachers (170 respondents), and university students (174 respondents). The survey utilized a questionnaire which is based on a psychometric model and allows for internal cross-checking of independent attitude measures. The analysis shows that for all subgroups nuclear power is the least preferred option. Those opposing nuclear power also have negative attitudes towards oil and are less favourable towards the other energy systems also. It was found that the subjects strongly related nuclear power to environmental risks (which they did not for solar, hydro, geothermal) and were not convinced about its economic benefits. They rated the technological benefits of all the five energy systems equally high and believed in sociopolitical implications of all energy systems except solar energy. Women are strongly less favourable towards nuclear power and oil than men. They are also more afraid of its risks and less convinced about its benefits. The influence of other variables like age, education and information source is rather low. The report also compares public attitudes towards nuclear power and geothermal energy in the vicinity of a geothermal site in Dumaguete City in Negros Oriental

  17. Do beef risk perceptions or risk attitudes have a greater effect on the beef purchase decisions of Canadian consumers?

    Yang, Jun; Goddard, Ellen

    2011-01-01

    Cluster analysis is applied in this study to group Canadian households by two characteristics, their risk perceptions and risk attitudes toward beef. There are some similarities in demographic profiles, meat purchases, and bovine spongiform encephalopathy (BSE) media recall between the cluster that perceives beef to be the most risky and the cluster that has little willingness to accept the risks of eating beef. There are similarities between the medium risk perception cluster and the medium risk attitude cluster, as well as between the cluster that perceives beef to have little risk and the cluster that is most willing to accept the risks of eating beef. Regression analysis shows that risk attitudes have a larger impact on household-level beef purchasing decisions than do risk perceptions for all consumer clusters. This implies that it may be more effective to undertake policies that reduce the risks associated with eating beef, instead of enhancing risk communication to improve risk perceptions. Only for certain clusters with higher willingness to accept the risks of eating beef might enhancing risk communication increase beef consumption significantly. The different role of risk perceptions and risk attitudes in beef consumption needs to be recognized during the design of risk management policies.

    The objective of this study is to examine risk taking and risk perception associations with perceived exertion, pacing, and performance in athletes. Two experiments were conducted in which risk perception was assessed using the domain-specific risk taking (DOSPERT) scale in 20 novice cyclists (experiment 1) and 32 experienced ultramarathon runners (experiment 2). In experiment 1, participants predicted their pace and then performed a 5-km maximum effort cycling time trial on a calibrated Kingcycle mounted bicycle. Split times and perceived exertion were recorded every kilometer. In experiment 2, each participant predicted their split times before running a 100-km ultramarathon. Split times and perceived exertion were recorded at seven checkpoints. In both experiments, higher and lower risk perception groups were created using median split of DOSPERT scores. In experiment 1, pace during the first kilometer was faster among lower risk perceivers compared with higher risk perceivers (t(18) = 2.0, P = 0.03) and faster among higher risk takers compared with lower risk takers (t(18) = 2.2, P = 0.02). Actual pace was slower than predicted pace during the first kilometer in both the higher risk perceivers (t(9) = -4.2, P = 0.001) and lower risk perceivers (t(9) = -1.8, P = 0.049). In experiment 2, pace during the first 36 km was faster among lower risk perceivers compared with higher risk perceivers (t(16) = 2.0, P = 0.03). Irrespective of risk perception group, actual pace was slower than predicted pace during the first 18 km (t(16) = 8.9, P risk perception groups. Initial pace is associated with an individual's perception of risk, with low perceptions of risk being associated with a faster starting pace. Large differences between predicted and actual pace suggest that the performance template lacks accuracy, perhaps indicating greater reliance on momentary pacing decisions rather than preplanned strategy.

  20. Acceptable risks: occupational health in the nuclear industry

    Brown, M.S.

    1980-01-01

    This thesis examines the risk of working in the nuclear power industry. It reviews the history of the industry, government regulatory activities, and current scientific evidence of the health effects of radiation exposure. A discussion of current controversies over reduction in exposure limits is presented along with an analysis of the issues and problems associated with determinations of acceptable workplace risks. The thesis analyzes the controversy in terms of the acceptability of risk. The question of acceptability does not lend itself to technical evaluations of risks, costs, and benefits but is a social judgment of the necessity of a particular occupation or industry in society. At issue is the level of profits foregone by reductions in risk. This document concludes that the legitimacy of decisions about acceptable risks rests on the informed participation of all interested parties, including workers, in a process of defining socially necessary production. There must be opportunities to refuse higher risk jobs without losing a livelihood and adequate compensation for workers who accept hazardous jobs for the benefit of society

    Economic growth in the past decades has resulted in change in consumption pattern and emergence of tech-savvy generation with unprecedented increase in the usage of social network technology. In this paper, the technology acceptance value gap adapted from the technology acceptance model has been applied as a tool supporting social network technology usage and subsequent promotion of sustainable consumption. The data generated through the use of structured questionnaires have been analyzed using structural equation modeling. The validity of the model and path estimates signifies the robustness of Technology Acceptance value gap in adjudicating the efficiency of social network technology usage in augmentation of sustainable consumption and awareness. The results indicate that subjective norm gap, ease-of-operation gap, and quality of green information gap have the most adversarial impact on social network technology usage. Eventually social networking technology usage has been identified as a significant antecedent of sustainable consumption.

    This report describes some of the regulatory and control functions legally conferred upon the Argentine Nuclear Regulatory Authority concerning radiological risks, as well as a critical analysis of the radiological risk acceptance criteria contained in the Argentine regulatory system. A summary of the application of regulatory standards AR 3.1.3. - 'Radiological criteria related to accidents in nuclear power reactors' and AR 4.1.3. - 'Radiological criteria related to accidents in research reactors' to concrete cases is made, while the favourable and unfavourable aspects of the risk acceptance criteria are discussed. The conclusion is that the Argentine regulatory system contains adequate radiological risk acceptance criteria, that the latter are consistent with the radiological protection principles applicable to man and that, for the moment, there is no need to perform any modifications that would broaden the conceptual framework on which such criteria are based.

  7. Surveying perceptions of landslide risk management in Norway

    Enhanced precipitation due to climate change leads to increase in both frequency and intensity of landslides in Norway. A proactive approach to risk management is therefore required to significantly reduce the losses associated with landslides. Opinions and perceptions from practitioners on the performance of landslide risk management can provide insights on areas for improvement in the landslide risk management strategies in Norway. The Risk Management Index (RMI), proposed by Cardona et al. (2004), is a well-established method to measure perceptions of disaster management of selected actors holistically. The RMI is measured based on opinion questionnaires to technical staff, decision-makers, and stakeholders involved in all stages of risk reduction strategies. It is a composite index that considers a wide variety of strategies to manage risks, including structural and non-structural measures, acceptance strategies, disaster management, and risk transfer. The RMI method was modified to be implemented in landslide hazards and to fit with Norwegian conditions. An opinion survey was conducted in autumn 2015 to measure perceptions of landslide risk management in Norway. Perceptions were surveyed for two time periods: 2015 and 2050, and are based on national, county, and municipality levels. Based on the survey results, performance of landslide risk management at any administrative levels in Norway is perceived to improve from `significant' in 2015 to `significant' to `outstanding' in 2050. Knowledge and technology, climate, risk perceptions, and anthropogenic activities are mostly considered by respondents for their 2050 perceptions. Several aspects of landslide risk management in Norway can be improved. For example, landslide hazard evaluation and mapping should be prioritised in Norway. Upgrading, retrofitting, and reconstruction of assets may also be included in the landslide risk reduction strategies. In addition, there should be more focus on inter

  8. Maternal Acceptance: Its Contribution to Children's Favorable Perceptions of Discipline and Moral Identity.

    The authors examined the contribution of maternal acceptance or warmth to children's and adolescents' perceptions of discipline and formation of moral identity. The sample consisted of 93 male and female students from Grades 5, 8, and 10 and their mothers. Students completed measures pertaining to perceived maternal discipline practices and acceptance-rejection, as well as moral identity. A subsample of mothers reported on their accepting or rejecting actions toward their children. Children were more likely to feel accepted, if their mothers used inductive discipline (vs. power assertion and love withdrawal). Perceived acceptance was also related to more favorable discipline evaluations in certain respects. Specifically, inductive discipline recipients who felt accepted also evaluated induction as appropriate and responded to it with positive and guilt-related emotions. Power assertion was evaluated as appropriate among those children who did feel accepted. Finally, among inductive discipline recipients, those who felt accepted also reported higher moral identity.

    The communication of natural hazards and their consequences is one of the more relevant ethical issues faced by scientists. In the last years, social studies have provided evidence that risk communication is strongly influenced by the risk perception of people. In order to develop effective information and risk communication strategies, the perception of risks and the influencing factors should be known. A theory that offers an integrative approach to understanding and explaining risk perception is still missing. To explain risk perception, it is necessary to consider several perspectives: social, psychological and cultural perspectives and their interactions. This paper presents the results of the CATI survey on seismic risk perception in Italy, conducted by INGV researchers on funding by the DPC. We built a questionnaire to assess seismic risk perception, with a particular attention to compare hazard, vulnerability and exposure perception with the real data of the same factors. The Seismic Risk Perception Questionnaire (SRP-Q) is designed by semantic differential method, using opposite terms on a Likert scale to seven points. The questionnaire allows to obtain the scores of five risk indicators: Hazard, Exposure, Vulnerability, People and Community, Earthquake Phenomenon. The questionnaire was administered by telephone interview (C.A.T.I.) on a statistical sample at national level of over 4,000 people, in the period January -February 2015. Results show that risk perception seems be underestimated for all indicators considered.

    1982-01-01

    As a consequence of the problems posed by modern technologies (e.g. nuclear power), a new discipline 'risk assessment' has developed over the last decade. The paper describes, first, some studies on determinants of perceived risk, e.g. frequency of accidents, catastrophic potential, voluntariness, dreadfulness, and controllability. Cognitive factors which help explaining research findings include availability, overconfidence, and perceptual set. Secondly, studies on the acceptability of risk are presented in which the focus is on the relation between perceived risk and perceived benefit. Following this, a brief outline of methods is given that have been suggested for determining the acceptability of risk (revealed preferences, expressed preferences, cost-benefit analysis, and decision analysis). Finally, the impact of the development of risky technologies and of risk research is discussed as it is evidenced in the controversies that have emerged within the scientific community, between science and politics, and between science and the public.

    Objective: To determine knowledge, perception, and acceptance related to cervical cancer, HPV vaccination and screening for cervical cancer among Indonesian women, particularly in Yogyakarta province. Methods: A convenience sample of 392 women consists of 192 young women, 100 mothers of girls aged 12 – 15 years, and 100 adult women in Yogyakarta province, Indonesia was participated in this study. A self-administered paper-based questionnaire was used to determine demographics characteristics of respondents, as well as their knowledge – perceptionacceptance related to cervical cancer, HPV vaccination, and screening for cervical cancer. Data collection were conducted during December 2013 to March 2014. Descriptive statistics was used to analyze description of demographics characteristics, knowledge, perception, and acceptance; while crosstab analysis using Chi-Square was used to analyze the relationship between demographics characteristics versus knowledge, perception, and acceptance. Results: This study found that knowledge and perception regarding cervical cancer, HPV vaccination, and screening for cervical cancer among women in Indonesia, particularly in Yogyakarta Province were still insufficient, however the acceptance was good. Among female young women, 64% had good knowledge, 62% had positive perception of cervical cancer and HPV vaccination, and 92% tended to accept HPV vaccination. Among mothers of girls aged 12 – 15 years, 44% had good knowledge, 46% had positive perception of cervical cancer and HPV vaccination, and 91% tended to accept HPV vaccination for their daughters. Among adult women, 68% had good knowledge, 57% had positive perception of cervical cancer and screening for cervical cancer, and 90% tended to accept cervical cancer screening. In general, demographics characteristics of having experience and exposure to information had significant relationship with knowledge, perception, and acceptance of HPV vaccination and screening for

    There is ambiguity with regard to what counts as an acceptable level of risk in clinical research in pregnant women and there is no input from stakeholders relative to such research risks. The aim of our paper was to explore what stakeholders who are actively involved in the conduct of clinical research in pregnant women deem an acceptable level of risk for pregnant women in clinical research. Accordingly, we used the APOSTEL VI study, a low-risk obstetrical randomised controlled trial, as a case-study. We conducted a prospective qualitative study using 35 in-depth semi-structured interviews and one focus group. We interviewed healthcare professionals, Research Ethics Committee members (RECs) and regulators who are actively involved in the conduct of clinical research in pregnant women, in addition to pregnant women recruited for the APOSTEL VI case-study in the Netherlands. Three themes characterise the way stakeholders view risks in clinical research in pregnant women in general. Additionally, one theme characterises the way healthcare professionals and pregnant women view risks with respect to the case-study specifically. First, ideas on what constitutes an acceptable level of risk in general ranged from a preference for zero risk for the foetus up to minimal risk. Second, the desirability of clinical research in pregnant women in general was questioned altogether. Third, stakeholders proposed to establish an upper limit of risk in potentially beneficial clinical research in pregnant women in order to protect the foetus and the pregnant woman from harm. Fourth and finally, the case-study illustrates that healthcare professionals' individual perception of risk may influence recruitment. Healthcare professionals, RECs, regulators and pregnant women are all risk adverse in practice, possibly explaining the continuing underrepresentation of pregnant women in clinical research. Determining the acceptable levels of risk on a universal level alone is insufficient

  13. Stakeholder Perceptions of Risk in Construction

    Safety management in construction is an integral effort and its success requires inputs from all stakeholders across design and construction phases. Effective risk mitigation relies on the concordance of all stakeholders’ risk perceptions. Many researchers have noticed the discordance of risk perceptions among critical stakeholders in safe construction work, however few have provided quantifiable evidence describing them. In an effort to fill this perception gap, this research performs an experiment that investigates stakeholder perceptions of risk in construction. Data analysis confirms the existence of such discordance, and indicates a trend in risk likelihood estimation. With risk perceptions from low to high, the stakeholders are architects, contractors/safety professionals, and engineers. Including prior studies, results also suggest that designers have improved their knowledge in building construction safety, but compared to builders they present more difficultly in reaching a consensus of perception. Findings of this research are intended to be used by risk management and decision makers to reassess stakeholders’ varying judgments when considering injury prevention and hazard assessment.

    While energy need (or demand) and the risks of energy production and use may be objectively quantified, risk acceptance embodies a subjective element of preferences and values. Yet, as demonstrated by the nuclear controversy in the United States, public acceptance is essential to the beneficial uses of radiation. The statement of the objectives and purposes of the Health Physics Society and our application of it are proposed as offering useful criteria for risk acceptance. The principle of comparing risk with a number of those regularly accepted in everyday life is emphasized. On this basis, it is concluded that the expenditures to attain currently applicable or proposed 'as low as practicable' (or 'as low as readily achievable') levels for the nuclear fuel cycle are disproportionate to those addressed to other sources of general public exposure to radiation. They are also disproportionate compared to those addressed to a variety of public health risks. It is suggested that sensible priorities for radiation and public health protection might be achieved by the application of a de minimus negligible (but nonzero) level of probable risk.

    This study was undertaken to understand how consumers in the United States perceive umami-rich products, specifically low sodium chicken noodle soup. Results suggest that the addition of monosodium l-glutamate (MSG) at a concentration of 0.1% to 0.5%, alone or in synergy with 5'-ribonucleotides of inosine monophosphate (IMP) at 0.1% not only increases consumer acceptance but also positively impacts other aspects of consumer perception. Regardless of concentration of MSG and IMP, samples enhanced in umami compounds were perceived as more savory, flavorful, and less bland while providing a more homemade, fresh, and healthy wholesome taste than a control sample. From a functional and emotional benefit standpoint, when consuming umami-rich samples, consumers reported feeling significantly higher general satisfaction (they felt more content, relaxed, satisfied, less disappointed, dissatisfied…) and heightened positive emotions (happy, excited, indulgent…) than under the control condition. The feeling of being healthy while consuming the dish was not compromised. Last, when asked how they would feel if serving the soup sample to their family or friends, consumers projected feeling more positively under the umami-rich conditions (more happy, competent, loving, less dissatisfied or disappointed) compared to the control condition. © 2015 Institute of Food Technologists®

    This publication reports and comments the results of a survey performed every 6 years on the perception of exposure to environmental risks. It notably comments the evolution between 2007 and 2013 of the perception of exposure to different types of risks: seismic risks, terrorism, major industrial risks, flooding risks, nuclear risks, food-related risks, risks related to climate change, unemployment, air pollution, and cancer. The perceptions of inhabitants of cities exposed or not exposed to some risks (industrial, climate, flooding) are compared. Risks are ranked from very important to not important at all. The influence of the existence of a risk when choosing to settle in a dwelling is also assessed, as well as the already lived consequences of catastrophes, the level of concern about possible consequences of a catastrophe, the respective roles of the State and citizen in the field of risk prevention, the opinions on law efficiency to protect people and goods, the knowledge of prevention arrangements against natural and technological risk, the level of confidence in public action regarding risks to which interviewed people are actually exposed (industrial risks, risks related to climate, flooding)

    Improvements in communications technology enable consumers to receive information through diverse channels. In the case of avian influenza, information repeated by the mass media socially amplifies the consumer awareness of risks. Facing indeterminate risks, consumers may feel anxious and increase their risk perception. When consumers trust the information published by the media, their uncertainty toward avian influenza may decrease. Consumers might take some actions to reduce risk. Therefore, this study focuses on relationships among trust in messages, risk perception and risk reduction preferences. This study administered 525 random samples and consumer survey questionnaires in different city of Taiwan in 2007. Through statistical analysis, the results demonstrate: (1) the higher the trust consumers have in messages about avian influenza, the lower their risk perceptions are; (2) the higher the consumers’ risk perceptions are and, therefore, the higher their desired level of risk reductive, the more likely they are to accept risk reduction strategies; (3) consumer attributes such as age, education level, and marital status correlate with significant differences in risk perception and risk reduction preferences acceptance. Gender has significant differences only in risk reduction preferences and not in risk perception. PMID:23066394

    The objective of this study is to develop measurement indices for social risk acceptance of various power systems(nuclear, coal, oil, LNG, hydro, wind, solar) and compare them empirically. In order to measure social risk acceptance of various power systems, four measurement fields and twelve measurement indices were developed. Measurement areas contains rationality, emotion, trust, communication. Each measurement field has two or three measurement indices. Rationality field has indices of amount of knowledge, recognition of technological utility, risk controllability. Emotion field has indices of experiences, risk recognition. Trust field has indices of openness, sincerity, willingness of sharing knowledge and experiences. Communication field has indices of scientist's roll, media's roll, public relations. Based on these measurement field and indices, this study made questionnaire and surveyed citizens to compare deciding factors of social acceptance on risk of various power systems. Questionnaire respondents were sampled from six different groups, including power system specialists, highschool students, university students, general citizen, professors and environmental NGOs. The methodologies used to analyze the deciding factors of social acceptance on risk of various power systems were frequency analysis, cross-tab analysis, t-test and ANOVA analysis. AHP method was used to analyze power system specialists' perception on relative severance and priority among measurement fields and indices.

    Atmospheric pollution has emerged as a major public health issue in China. Public perception and acceptable risk levels of air pollution can prompt individual behavioral changes and play a major role in the public's response to health risks. Therefore, to explore these responses and evaluate what constitutes publicly acceptable concentrations of fine particulate matter (PM 2.5 ), questionnaire surveys were conducted in three representative cities of China: Beijing, Nanjing, and Guangzhou. Great differences in public risk perception were revealed. Public perception of the health effects of air pollution (Effect) and familiarity with it (Familiarity) were significantly higher in the winter than in the summer, and also during severe haze days compared with typical days. The public perception of trust in the government (Trust) was consistent across all conditions. Exposure to severe haze pollution and experiencing harms from it were key factors influencing public willingness to respond to haze. These results reflected individual exposure levels correlating closely with risk perception and acceptance of PM 2.5 . However, a crucial gap exists between public acceptable risk levels (PARL) of air pollution and the policy objectives of the State Council's Action Plan. Thus, policymakers can utilize this study to develop more targeted measures to combat air pollution. Copyright © 2017 Elsevier Inc. All rights reserved.

The questions addressed the perception of risks, the role of scientific experts, the usefulness and breaks on the diffusion of expertise results, the perception of pluralist bodies, and the Fukushima accident. The answers are analysed and discussed with respect to fifteen hazardous situations, to their opinion of expertise, and to their opinion on safety audit and information

  4. Risk Assessment, Transparency and Public Perception

    2003-01-01

    To examine the US. public perception of risk now, in mid-2003, is a matter of capturing a snap shot at a particular moment of a specific circumstance. Over the past two years, Americans have gone from what they considered to be a fast-paced, high-stress, rapidly-changing, but fumiliar lifestyle and culture, to an uncertain existence that starts and stops with 'breaking news'. For people who previously felt confident about their understanding of what is or is not likely to happen, is or is not dangerous, and is or is not acceptable, there is now doubt. Studies of human behavior in judgement and decision making point out the importance of 'affect'. People's first reactions are based on good or bad experiences or images and not a rational weighing of pros and cons. The study results imply that people base their judgments of an activity or a technology not only on what they think about it but also on what they feel about it. It is unreasonable to expect that the public will accept decisions made for them regarding nuclear waste disposal and transport considering the negative images associated with radiation combined with the threat of possible terrorism. The federal government does face, as one of its most important tasks, protecting the health, safety and security of its people. it is also necessary for the government to consider the issue of nuclear waste disposal, but combining the two and using national security to defend nuclear waste policies is publically unacceptable. In a democracy, methods of how to best protect the people should be a matter of public debate and should be implemented only after public approval. One sure path to the erosion of democracy is govemmental decision making without the consent of the peopie, in the name of a (albeit honorable) principle. When government defends its own ideology and implements its own conception of what is best for the nation, democracy is lost

    Within research on individual variations in risk perception, personality has been suggested as one important factor. In the present study, personality traits (44 items from the Big Five inventory) were investigated in relation to risk perception in transport and transport behavioural adaptations. In a sample of 312 participants, we found that the personality trait 'emotional stability versus neuroticism' was negatively correlated with risk perception (operationalised as "thinking about the possibility") of an accident (-0.38) and an unpleasant incident, such as crime, violence, robbery (-0.25). 'Agreeableness' was also negatively related to risk perception, however first and foremost in relation to perceived risk for unpleasant incidents on transport modes in which one interacts with other people (0.25). Moreover, regression analyses showed that 'emotional stability' was a significant predictor of behavioural adaptations on bus. Regression analyses explained between 17 and 26 percent of variance in behavioural adaptations. The results show that different groups of people vary systematically in their perception of risk in transport. Furthermore, these differences are manifest as a difference in risk-preventive behaviour at a strategic level, i.e. as decisions about avoiding risky situations. Copyright © 2012 Elsevier Ltd.

    Work habits are non-technical skills that are an important part of job performance. Although non-technical skills are usually evaluated on a relative basis (i.e., "grading on a curve"), validity of evaluation on an absolute basis (i.e., "minimum passing score") needs to be determined. Survey and observational study. None. None. The theme of "work habits" was assessed using a modification of Dannefer et al.'s 6-item scale, with scores ranging from 1 (lowest performance) to 5 (highest performance). E-mail invitations were sent to all consultant and fellow anesthesiologists at Mayo Clinic in Florida, Arizona, and Minnesota. Because work habits expectations can be generational, the survey was designed for adjustment based on all invited (responding or non-responding) anesthesiologists' year of graduation from residency. The overall mean±standard deviation of the score for anesthesiologists' minimum expectations of nurse anesthetists' work habits was 3.64±0.66 (N=48). Minimum acceptable scores were correlated with the year of graduation from anesthesia residency (linear regression P=0.004). Adjusting for survey non-response using all N=207 anesthesiologists, the mean of the minimum acceptable work habits adjusted for year of graduation was 3.69 (standard error 0.02). The minimum expectations for nurse anesthetists' work habits were compared with observational data obtained from the University of Iowa. Among 8940 individual nurse anesthetist work habits scores, only 2.6% were habits scores were significantly greater than the Mayo estimate (3.69) for the minimum expectations; all Phabits of nurse anesthetists within departments should not be compared with an appropriate minimum score (i.e., of 3.69). Instead, work habits scores should be analyzed based on relative reporting among anesthetists. Copyright © 2017 Elsevier Inc. All rights reserved.

    Accidents, one often hears, "happen"; we accept, and even expect, that they will be part of daily life. But in situations in which injury or death result, judgments of responsibility become critical. How might our perceptions of risk influence the ways in which we allocate responsibility for an accident? Drawing from attribution and risk perception theory, this study investigates how perceived controllability and desirability of risk, in addition to perceived danger and recreational risk-taking, relate to attributions of responsibility for the cause of unintentional injury in a unique setting: U.S. national parks. Three parks, Mount Rainier, Olympic, and Delaware Water Gap, provide the setting for this survey-based study, which considers how park visitors (N = 447) attribute responsibility for the cause of a hypothetical visitor accident. Results suggest that respondents tended to make more internal (i.e., related to characteristics of the victim), rather than external (i.e., related to characteristics of the park, or park management) attributions. As respondents viewed park-related risk as controllable, they were more likely to attribute the cause of the accident to the victim. Moreover, among other significant variables, having experienced a similar accident predicted lower internal causal attribution. Opportunities for future research linking risk perception and attribution variables, as well as practical implications for the management of public outdoor settings, are presented. © 2013 Society for Risk Analysis.

    Doenjang is a traditional Korean food and is widely used for many Korean foods. Consumer perception and consumer acceptability on the typical sensory characteristics of traditional Doenjang remain unknown. The objective of the current study was to determine the consumer perception on traditional Doenjang characteristics and how preexisting consumer perception influenced the consumer liking for traditionally and commercially manufactured Doenjang. A consumer survey was conducted by presenting 26 sensory descriptions to consumers (n = 82) for check-all-that-apply measurement. Then, a consumer acceptance test was conducted over 2 d on 2 Doenjang samples representing commercially produced Doenjang and traditionally produced Doenjang: Day 1 consumers evaluated without any information (n = 182), and day 2 consumers evaluated samples informed that both samples were made by the "traditional" method (n = 109). Two-way ANOVA and multivariate analyses were conducted. Consumers' preexisting perceptions on the typical sensory characteristics of traditionally made Doenjang were similar in that they associate "gu-soo flavor," "dark color," "flavorful," and "well-fermented flavor" regardless of consumer demographics and Doenjang user status. However, these consumer perceptions on sensory attributes of traditional Doenjang did not agree with desirable sensory attributes for consumer liking, in that consumers preferred the commercially made Doenjang regardless of the evaluation condition and consumer user status. Findings from the current study therefore suggested a discrepancy between the preexisting current consumer perception and actual consumer acceptability of traditional Doenjang products. © 2014 Institute of Food Technologists®

    The aim of this study is a quantification of public risk perception towards the nuclear field so as to be considered in decision making whenever the public involvement is sought. The proposed model includes both qualitative factors such as familiarity and voluntariness and numerical factors influencing risk perception, such as probability of occurrence and severity of consequence. Since part of these factors can be characterized only by qualitative expressions and the determination of them are linked with vagueness, imprecision and uncertainty, the most suitable method for the risk level assessment is Fuzzy Logic, which models qualitative aspects of knowledge and reasoning processes without employing precise quantitative analyses. This work, then, offers a Fuzzy-Logic based mean of representing the risk perception by a single numerical feature, which can be weighted and accounted for in decision making procedures. (author)

  14. The influence of knowledge on risk perception

    International Nuclear Information System (INIS)

    Kanda, Reiko; Fujimoto, Kenzo; Kobayashi, Sadayoshi

    1997-01-01

    Many researches on risk perception have often been concerned with reaction of the public to modern technology. A major concern is the public fear of such new technology as nuclear power and genetic engineering. When the perceived risk was examined using a risk ranking technique, Japanese school teachers, university students and also NIRS staffs (female clerical staffs and researchers) viewed nuclear power to be much riskier than the objective estimation. Many technical experts have believed that this great fear results from an overestimation of risk by the public due to lack of scientific knowledge. So far, several studies reported the results to examine the correlation of the perception of some risk sources with knowledge about them, although their conclusions are inconsistent. When the perceived risk by trainees on a radiation protection course in NIRS was examined, nuclear power was rated as the second and 14th among 30 risk items by those who majored in life sciences in college and by those in physics, chemistry or technology, respectively. The perceived risk of nuclear power did not change among trainees by training offered fundamental knowledge about radiation during the course. On the other hand, the orders of smoking and alcoholic beverages rose considerably. Our results are consistent with the previous reports, i.e., what people learn initially about risk source has more important role in risk perception than what they learn later, and the increase of perceived risk is more easier than its decrease. Knowledge is now recognized as one of the factors which influence on risk perception. However, a special emphasis is now placed on risk communication in order to make partnership between communicators and receivers in the risk management. (author)

    Risk is generally defined as the "combination of the probability of the occurrence of an event and its negative consequences" ( UNISDR, 2009). However, the perception of a risk differs among cultures regarding different features such as the context,causes, benefits or damage. Risk perception is the subjective valuation of the probability of an event happening and how concerned individuals or groups are with the consequences (Sjöberg, 2004). Our study is based on an existing framework for risk perception (Rehn and Rohrmann, 2000). We analyse the characteristics of the risk perception regarding extreme events (e.g.droughts) and how the perception of the group drives the action to manage the risk. We do this to achieve an overview of the conditions that let stakeholders join each other to improve risk management especially when governments are not reacting properly. For our research, attention is paid on risk perception of Multi-Sector Partnerships not taking into account the individual level of risk perception. We focus on those factors that make risk management effective and increase resilience. Multi-Sector Partnerships, considered as significant governance structures for risk management, might contribute to reduce vulnerability in prone areas to natural hazards and disasters. The Multi-Sector Partnerships used for our research are existing partnerships identified in the cases studies of the European project ENHANCE. We implement a survey to analyse the perception of risk in the case studies. That survey is based on the Cultural Theory (Douglas and Wildavsky, 1982)and the Protection Motivation Theory (Rogers, 1975). We analyse the results using the Qualitative-Comparative Analysis proposed by Ragin in 1987. The results show the main characteristics of a risk culture that are beneficial to manage a risk. Those characteristics are shaped by the perception of risk of the people involved in the partnership, which in turn shapes their risk management. Nevertheless, we

    Carbon Dioxide Capture and Storage (CCS) is assumed to be one of the key technologies in the mitigation of climate change. Public acceptance may have a strong impact on the progress of this technology. Benefit perception and risk perception are known to be important determinants of public acceptance of CCS. In this study, the prevalence and effect of cognitive concepts underlying laypeople's risk perception and benefit perception of CCS were examined in a representative survey (N=654) in Switzerland. Results confirm findings from previous qualitative studies and show a quantification of a variety of widespread intuitive concepts that laypeople hold about storage mechanisms as well as about leakage and socioeconomic issues, which all appeared to influence risk perception and benefit perception. The perception of an overpressurized reservoir and concerns about diffuse impacts furthermore amplified risk perception. Appropriate images about storage mechanisms and climate change awareness were increasing the perception of benefits. Knowledge about CO2 seemed to lower both perceived benefits and perceived risks. Implications for risk communication and management are discussed.

    Since most of the empirical work on risk perception has been conducted in the 1970s and few studies are available that claim to span the full range of psychological, sociological and cultural variables, the Center of Technology Assessment in Stuttgart (Germany) has conducted a representative survey in the German State of Baden-Wuerttemberg on risk perception in the general population. In addition, a qualitative investigation based on a sample of 62 respondents was launched in 2001. The objective of the study was to determine the relative importance of psychometric, stigma-related, social value-related, trust-related and cultural variables in explaining risk perception and acceptance. The following report summarizes the results of these investigations. (orig.)

    Full Text Available Ruth Webster1, Emma Heeley21Cardiovascular Division, 2Neurological and Mental Health Division, The George Institute for International Health, Camperdown, NSW, AustraliaAbstract: Cardiovascular disease (CVD is still the leading cause of death and disability worldwide despite the availability of well-established and effective preventive options. Accurate perception of a patient’s risk by both the patient and the doctors is important as this is one of the components that determine health-related behavior. Doctors tend to not use cardiovascular (CV risk calculators and underestimate the absolute CV risk of their patients. Patients show optimistic bias when considering their own risk and consistently underestimate it. Poor patient health literacy and numeracy must be considered when thinking about this problem. Patients must possess a reasonably high level of understanding of numerical processes when doctors discuss risk, a level that is not possessed by large numbers of the population. In order to overcome this barrier, doctors need to utilize various tools including the appropriate use of visual aids to accurately communicate risk with their patients. Any intervention has been shown to be better than nothing in improving health understanding. The simple process of repeatedly conveying risk information to a patient has been shown to improve accuracy of risk perception. Doctors need to take responsibility for the accurate assessment and effective communication of CV risk in their patients in order to improve patient uptake of cardioprotective lifestyle choices and preventive medications.Keywords: risk perception, cardiovascular disease, cardioprotective lifestyle

    The value of health information technology (IT) ultimately depends on end users accepting and appropriately using it for patient care. This study examined pediatric intensive care unit nurses' perceptions, acceptance, and use of a novel health IT, the Large Customizable Interactive Monitor. An expanded technology acceptance model was tested by applying stepwise linear regression to data from a standardized survey of 167 nurses. Nurses reported low-moderate ratings of the novel IT's ease of use and low to very low ratings of usefulness, social influence, and training. Perceived ease of use, usefulness for patient/family involvement, and usefulness for care delivery were associated with system satisfaction (R 2  = 70%). Perceived usefulness for care delivery and patient/family social influence were associated with intention to use the system (R 2  = 65%). Satisfaction and intention were associated with actual system use (R 2  = 51%). The findings have implications for research, design, implementation, and policies for nursing informatics, particularly novel nursing IT. Several changes are recommended to improve the design and implementation of the studied IT.

    Now, public acceptance plays a central role in the nuclear energy. Public concerns on safety and sustainability of nuclear energy, ground nuclear power in many countries and territories to a stop or even a downfall. In this study, an e-learning framework by using Internet, is proposed for public education in order to boost public perception on nuclear energy, which will certainly affect public acceptance toward it. This study aims at investigating public perception and acceptance on nuclear energy in a continuous and accurate manner. In addition, this e-learning framework can promote public perception on nuclear energy by using teaching material with a graphical hierarchy about knowledge of nuclear energy. This web-based e-learning framework mainly consists of two components: (1) an e-learning support module which continuously investigates public perception and acceptance toward nuclear energy and teaches public knowledge about nuclear energy; (2) an updating module which may improve the education materials by analyzing the effect of education or proving the materials submitted by the visitors through Wiki pages. Advantages and future work of this study are also generally described. (author)

    The purpose of this study is to analyze the characteristics of risk perception associated with nuclear power plants in the framework of the behavioral economics, such as prospect theory. Due to the bounded rationality of the people, the public tends to overestimate the risk of nuclear power, especially after the disaster of Fukushima Daiichi in Japan. Social acceptance is an essential element for the nuclear power plants, but nuclear option is getting regarded as a risky choice. On the other hand, experts define and measure risk by the calculation of the probability of damage to the core as a result of sequences of accidents identified by the study. However, this approach also involves limitations to some extent. We explore a possible way to close the gap under in the by wider social context with consideration of risk trade-off among various risk factors, rather than focusing only on nuclear issue. (author)

    Risk perception is a subjective assessment of the actual or potential threat to one's life or, more broadly, to one's psychological well-being. Given the various risks associated with later life, a valid and reliable integrative screening tool for assessing risk perception among the elderly is warranted. The study examined the psychometric properties and factor structure of a new integrative risk perception instrument, the Perceived Risk Scale. This eight-item measure refers to various risks simultaneously, including terror, health issues, traffic accidents, violence, and financial loss, and was developed specifically for older adults. An online survey was conducted with 306 participants aged 50 years and older. The scale was examined using exploratory factor analysis and concurrent validity testing. Factor analysis revealed a two-factor structure: later-life risks and terror risks A high percentage of explained variance, as well as internal consistency, was found for the entire scale and for both factors. Concurrent validity was supported by significant positive associations with participants' depression and negative correlations with their life satisfaction. These findings suggest that the Perceived Risk Scale is internally reliable, valid, and appropriate for evaluating risk perception in later life. The scale's potential applications are discussed. © The Author(s) 2016.

    To examine published research which explores the perception and acceptability of microneedle technology for immunisation and to investigate the suitability of this technology for paediatric use. A series of keywords and their synonyms were combined in various combinations and permutations using Boolean operators to sequentially search four databases (PubMed, Web of Science, Embase and CINAHL). Following removal of duplications and irrelevant results, 12 research articles were included in the final literature review. The opinions of patients, parents, children and healthcare professionals (HCP) were collated. A positive perception and a high level of acceptability predominated. Microneedle technology research has been focussed on demonstrating efficacy with minimal focus on determining HCP/public perception and acceptability for paediatric use, exemplified by the paucity of studies presented in this review. Commercial viability will depend on HCP/public acceptability of microneedle technology. An effort must be made to identify the barriers to acceptance and to overcome them by increasing awareness and education in stakeholder groups pertaining to the paediatric population.

    A framework for relating the variables involved in the public perception of hazardous materials transportation is presented in which perceived risk was described in six basic terms: technical feasibility, political palatability, social responsibility, benefit assessment, media interpretation, and familiarity as a function of time. Scientists, the media and public officials contribute to the discussion of risks but ultimately people will decide for themselves how they feel and what they think. It is not sufficient to consider the public of not being enlightened enough to participate in the formulation of radioactive material transport policy. The framework provides the technologist with an initial formulation to better inform the public and to understand public perception

    A research project looking at the public's attitudes towards the siting of radioactive waste depositories is reported. The risk perception studies seek to compare expert and lay understanding of risk. Adverse public reactions to risk can only be understood if it is known how people relate to risks in their everyday or working lives. Social trends and experiences are important, for example, the adverse public opinion on the siting of nuclear waste facilities. A number of elements have been identified as common to different risk areas such as chemicals, drugs, food or radioactive waste. These are the clashing of values, polarization of beliefs or clashes of interest. (UK)

    A recent two-day meeting was called by the Royal Society to discuss all types of risks, but symptomatic of the concerns of most of those present, the discussion centred mainly on the risks inherent in energy production and use. Among the subjects considered were public perception of differing risks, and how these are ranked, and risks versus benefits. Quotations from and summaries of many of the papers presented show that it was generally felt that scientists must be very careful in the way that they use numerical assessments of risk and that they should pay more attention than they have to social and political factors.

    As in many other areas, there is a divide between lay and expert perceptions of risk within the food sector, and this can lead to disagreement over priorities in food risk management. The risk perception literature tends to stress that the parties involved in this disagreement have different...... concepts of risk and hence are bound more or less to talk at cross-purposes. This paper suggests an alternative analysis: In the light of moral theory, the conflicting perspectives can be understood as a genuine moral conflict. When this conflict is conceptualised, a rational dialogue becomes possible....... The paper reports a series of qualitative interviews with lay people and experts on zoonotic food risks. The interviews are used to reconstruct the values underlying some of the dominant perspectives. The conflict between these stylised perspectives is then analysed with the help of moral theory.

    Over the last few decades, Europe has suffered from a number of severe flood events and, as a result, there has been a growing interest in probing alternative approaches to managing flood risk via prevention measures. A literature review reveals that, although in the last decades risk evaluation has been recognized as key element of risk management, and risk assessment methodologies (including risk analysis and evaluation) have been improved by including social, economic, cultural, historical and political conditions, the theoretical schemes are not yet applied in practice. One main reason for this shortcoming is that risk perception literature is mainly of universal and theoretical nature and cannot provide the necessary details to implement a comprehensive risk evaluation. This paper therefore aims to explore a procedure that allows the inclusion of stakeholders' perceptions of prevention measures in risk assessment. It proposes to adopt methods of risk communication (both one-way and two-way communication) in risk assessment with the final aim of making flood risk management more effective. The proposed procedure not only focuses on the effect of discursive risk communication on risk perception, and on achieving a shared assessment of the prevention alternatives, but also considers the effects of the communication process on perceived uncertainties, accepted risk levels, and trust in the managing institutions. The effectiveness of this combined procedure has been studied and illustrated using the example of the participatory flood prevention assessment process on the Sihl River in Zurich, Switzerland. The main findings of the case study suggest that the proposed procedure performed well, but that it needs some adaptations for it to be applicable in different contexts and to allow a (semi-) quantitative estimation of risk perception to be used as an indicator of adaptive capacity.

    The measures that are applied to regulate a certain practice, are based on the risk that implies the practice and in the acceptance of the above mentioned risk from the part affected by the practice. If the perception of the risk does not correspond to the reality the situation is unstable and it is possible to lose the control of the situation. When discrepancies exist in the Perception of the Risk on the part of different sectors of the society, they can produce serious conflicts that affect the establishment of the protection measures. The problem of the 'perception of the risk' rests on the fact that the technical people and the public use generally different reasoning and therefore its coincidence is almost fortuitous. The intuitive perception of the risk is often narrowly tied to a 'symbolic mechanism' and once established the symbolic relation can produce a psychological phenomenon by means of which the individuals resist to the reality, and the symbols make prevail over the facts in order not to alter the interior symbolic pre-established scheme. The perception of the risk appears in two different groups of persons: 1) The persons affected by the risk (the public); and 2) The persons who can modify this risk (operators). It is important that the perception of the risk is compatible with the scientific hypotheses to avoid conflicts in the situation 1 and to assure the control in the situation 2 (safety culture). The 'perception of the risk' is fundamental to support the control of a practice and it is possible to modify it across the communication. It is necessary to know which are all The Factors that affect the perception of the risk to be able to design a strategy of suitable communication. Across different studies it has been learned which are the factors that affect the perception of risk: 1) Some factors depend on the proper characteristics of the risk; 2) Others depend on the proper characteristics of the individuals and finally; 3) Other factors

    National physician validation systems aim to ensure lifelong learning through periodic appraisals of physicians' competence. Their effectiveness is determined by physicians' acceptance of and commitment to the system. This study, therefore, sought to explore physicians' perceptions and self-reported acceptance of validation across three different physician validation systems in Europe. Using a constructivist grounded-theory approach, we conducted semi-structured interviews with 32 respiratory specialists from three countries with markedly different validation systems: Germany, which has a mandatory, credit-based system oriented to continuing professional development; Denmark, with mandatory annual dialogs and ensuing, non-compulsory activities; and the UK, with a mandatory, portfolio-based revalidation system. We analyzed interview data with a view to identifying factors influencing physicians' perceptions and acceptance. Factors that influenced acceptance were the assessment's authenticity and alignment of its requirements with clinical practice, physicians' beliefs about learning, perceived autonomy, and organizational support. Users' acceptance levels determine any system's effectiveness. To support lifelong learning effectively, national physician validation systems must be carefully designed and integrated into daily practice. Involving physicians in their design may render systems more authentic and improve alignment between individual ambitions and the systems' goals, thereby promoting acceptance.

    Although the results of this paper are based on some restrictive assumptions and a limited amount of data, the authors nevertheless feel that they form a starting point for some new insights into the difficult problem of how to compare risks that have different characteristics. Today almost all regulatory agencies are facing the difficult question of ''how safe is safe enough.''. Although risk conversion factors may be able to play a useful role in setting safety criteria, it must also be recognized that RCFs as developed here are only a part of what needs to be considered. The RCFs involve only risk comparisons, whereas a safety criterion must surely include not only risk but cost and benefit as well

    The purpose of this paper is to present our main results from a survey carried out in Spain in the context of social risk perception. This survey is included in a broad project (PRISP) sponsored by the UE and the national Civil Protection Service, and carried out simultaneously in three countries: Spain, Italy and UK. The project combined qualitative and quantitative assessment methods, although only survey results are presented here. A random sample of 600 subjects from two different Spanish communities close to a COMAH chemical site was selected for the research. Main findings regarding, differential perception between both community populations, sex differences, and 'bias perception' of risks among others have been achieved. Main dimensions were obtained by multidimensional scaling and Factor Analysis. Dimensions reported here are similar to the usual findings from the psychometric paradigm. (authors)

    Radiation protection training and general employee training within the nuclear industry are designed to reduce workers' concerns about radiation and to develop skills that will protect against unwarranted exposures. Inaccurate perceptions about radiation by workers can cause a lack of adequate concern or exaggerated fears, which in turn can result in unnecessary radiation exposure to the worker or co-workers. The purpose of the study is threefold: (a) to identify health and safety concerns among nuclear power plant employees, (b) to discover variables that influence the perception of risk among employees, and (c) to ascertain if attitudes of the family, community, and the media affect workers' perception of risk. Workers identified five areas of concern: shift work, radiation, industrial safety, stress, and sabotage

  6. The effect of marriage and HIV risks on condom use acceptability in rural Malawi.

    2013-11-01

    A large and increasing proportion of HIV transmissions in sub-Saharan Africa occur within marriage. Condom use within marriage could, therefore, be an important prevention strategy, but there is considerable debate about whether married couples would be willing to use condoms. This paper contributes to this debate by identifying key factors that affect the acceptability of condom use within marriage and actual condom use among men and women in rural Malawi, using three waves of longitudinal data from 2004, 2006 and 2008. Specifically, we focused on the effect of (1) entry into first marriage, (2) respondent's HIV status, HIV perceptions, and risk behaviors, and (3) spouse's HIV characteristics on condom use acceptability within marriage and actual condom use with a spouse or steady partner. Using fixed-effects regression, we found that getting married coincides with a pronounced attitudinal shift regarding the acceptability of condom use within marriage that cannot be explained by differences in fertility status or selection into marriage. In addition, we found that, for women, perceived HIV status of the respondent and spouse generally had greater influence than actual HIV status on the acceptability of condom use within marriage and actual condom use with a spouse or steady partner, even after HIV status is known; while actual HIV status and HIV risk behaviors are generally more important among men. Although condom use within marriage remained low, these findings suggest that attitudes about and use of condoms are susceptible to change and that both marital status and perceptions of risk are important influences on condom use.

    The problems in the field of risk to inform the public are the difference in the risk perception by the public, between the risk realities and the image the public makes in himself, the confidence of the public towards those that give information, the readability ( and then understanding) of the information, the easiness for the public to forget the information. Solutions can be summarized by the same way: durability of information actions, information elaborated by safety authority, inhabitants associations, risk generator, elected members, supports of information clear and understandable.

  12. When is a threat only an acceptable risk

    The government has accepted the report 'Lead in the Environment' by the Royal Commission on Environmental Pollution which recommends the introduction of lead-free petrol. This acceptance is discussed in the context of how changes in policy on pollution legislation come about. It seems that broad changes in social attitudes are needed. Most changes start as environmental scares some of which capture public imagination, others do not. Scientists are a major influence on scares - some are ignored, others, where the risks may be less, are overplayed. Scares tend to follow a predictable pattern. The economic and social histories of some changes are presented - clean air, blue asbestos, the use of aerosols, fluoride in water, nuclear power, acid rain and VDU radiation. It is suggested that some scares are more a cry for help. Whether people are for or against technological development depends not on the risk they accept but on the different meanings of hazards they understand. To opponents of nuclear power, radiation is a metaphor for the whole insensitive, selfish, destructive industrial system. (U.K.)

  13. Nuclear Energy: General aspects of risk assessment and public acceptance

    While the peaceful uses of nuclear energy have progressed greatly in many countries and nuclear energy for electricity generation is greatly in demand also in developing countries, progress in this field is being threatened by minorities in those very countries which were originally responsible for this development. The paper analyses the various reasons behind this public opposition. The fear of nuclear war cannot be dispelled despite Government declarations promoting prohibition of the use of nuclear energy for military purposes and the numerous parties to the non-proliferation treaty. However, there is no cogent reason for transferring this mistrust to the peaceful uses of this source of energy. Also, hostility to technology is gaining ground in many countries and large groups of people are not prepared to accept the minimalised risks of nuclear energy. It is recommended that industry and politicians should pay more attention than in the past to the psychological question of acceptance of nuclear energy and lawyers have an important role to play in this context. They should co-operate more in gaining acceptance for the undeniable even if improbable remaining risks and integrate nuclear energy even closer into established law. (NEA) [fr

  14. Facts and values: on the acceptability of risks in children's sport using the example of rugby - a narrative review.

    2017-08-01

    A clash of values has been identified between those who assert that:1. all childhood injuries, regardless of origin, are inherently undesirable and should be prevented and;2. those who believe that some measure of injury to children is an acceptable compromise for the physical benefits associated with physical activity and the development of abilities to appraise and deal with risks.A debate regarding whether the tackles and collisions permitted in schools' rugby represent acceptable risks, and what steps should be taken if they do not, exemplifies the issue.Questions regarding the magnitude of injury risks in sport are issues of fact and can be quantified via the results of injury surveillance studies. Risks are neither high nor low in isolation; they are relatively high or low with reference to other activities or across groups participating in an activity. Issues of the acceptability of a given degree of risk are value dependent. Research regarding perceptions of risk reveals wide variations in the degree of risk people view as acceptable. Factors impacting on risk perception include whether the risks are well known and understood, whether they are 'dread' risks and the degree to which people undertake the risks voluntarily and feel they have control over them.Based on the evidence currently available, the risks to children playing rugby do not appear to be inordinately high compared with those in a range of other childhood sports and activities, but better comparative information is urgently needed. Further evidence, however, should not necessarily be expected to result in the resolution of acceptable risk debates-pre-existing values shape our perspectives on whether new evidence is relevant, valid and reliable. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Full Text Available Drivers’ risk perception is vital to driving behavior and traffic safety. In the dynamic interaction of a driver-vehicle-environment system, drivers’ risk perception changes dynamically. This study focused on drivers’ risk perception at unsignalized intersections in China and analyzed drivers’ crossing behavior. Based on cognitive psychology theory and an adaptive neuro-fuzzy inference system, quantitative models of drivers’ risk perception were established for the crossing processes between two straight-moving vehicles from the orthogonal direction. The acceptable risk perception levels of drivers were identified using a self-developed data analysis method. Based on game theory, the relationship among the quantitative value of drivers’ risk perception, acceptable risk perception level, and vehicle motion state was analyzed. The models of drivers’ crossing behavior were then established. Finally, the behavior models were validated using data collected from real-world vehicle movements and driver decisions. The results showed that the developed behavior models had both high accuracy and good applicability. This study would provide theoretical and algorithmic references for the microscopic simulation and active safety control system of vehicles.

    A research group at the Nuclear Research Centre, Julich, has attempted to trace public attitudes to nuclear power and their roots. The structure of attitudes, types of reasoning and the processes involved in deciding about nuclear power were measured. Intuitive perceptions of technology and risk were studied. Attitudes to nuclear energy are found to be the result of intuitive processes and opposition is 'natural' on the basis of intuitive reasoning. Many people who believe nuclear power to be hazardous nevertheless will accept it as inevitable for the economic advantages it will bring in the future. (U.K.)

    HPV is associated with malignancy in men, yet there is a lack of data on HPV knowledge, vaccine acceptability, and factors affecting vaccine acceptability in Greek men. This study aims to identify determinants of knowledge and willingness to vaccinate against HPV among high-risk Greek men. Men (n = 298) between the ages of 18 and 55 were enrolled from the STI and HIV clinics at "Andreas Syggros" Hospital in Athens, Greece from July-October 2015. Participants completed a survey on demographics, economic factors, sexual history, HPV knowledge, and vaccine acceptability. The majority of participants were younger than 40 (76.6%) and unmarried (84.6%). Our sample was 31.2% MSM (men who have sex with men), and 20.1% were HIV-positive. Most participants (>90%) were aware that HPV is highly prevalent in both men and women; however, fewer identified that HPV causes cancers in both sexes (68%) and that vaccination protects men and women (67%). Amongst participants, 76.7% were willing to vaccinate themselves against HPV, 71.4% an adolescent son, and 69.3% an adolescent daughter. HIV-positive men were more likely to be willing to vaccinate themselves (OR 2.83, p = .015), a son (OR 3.3, p = .015) or a daughter (3.01, p = .020). Higher income levels were associated with increased willingness to vaccinate oneself (OR 1.32, p = .027), a son (1.33, p = .032) or daughter (1.34, p = .027). Although there is a HPV knowledge gap, HPV vaccine acceptability is high despite lack of vaccine promotion to Greek men. Future studies should include lower-risk men to adequately inform public health efforts.

  19. Effects of risk communication on natural hazards on real estate owners' risk perception and risk behaviour

    In the last decade, in most of the European countries risk maps on natural hazards have been elaborated but there is so far little experience how to efficiently communicate these maps to the public. Recently, the public authorities of Zurich informed the owners of buildings located within the hazard zone on urban flood risks The owners received official letters containing information on potential danger, the probability of flood events, constructional safety measures, and guidelines for appropriate actions in case of an immediate flood. In the cover letter they were also encouraged to achieve more detailed information about the particular risks for their building using an online accessible risk map within a geographic information system (GIS). This risk communication campaign was based on the expectation that informing citizens increases their risk awareness and that citizens aware of risks are more likely to undertake actions to protect themselves and their property. There is, however, little empirical evidence that these expected outcomes can be achieved by written forms of risk communication. With this project we aim to find out to which degree a campaign of written risk communication can shape land owners risk perception and risk behaviour, and which other factors (e.g. trust in authorities, risk, risk zone category of the building) contributed to these outcomes... In collaboration with public authorities we conducted a survey among 1500 owners of buildings in the hazard zones in Zurich (50 % in blue zone, 50 % in yellow and yellow-white zone), that is 14% of all persons who were addressed by the authorities of the city. The standardized questionnaire comprises in particular items measuring respondents' evaluation of the virtual and physical information material, the time they spent for studying the information material, the dimensions of their risk perception, their acceptability of risks and their preparedness to implement constructional and other safety

    Most analytical assessments of potential impacts on the environment from US Department of Energy (DOE) activities receive, at some point in their development, public scrutiny. The objective of this paper is to discuss the apparent perception of these assessments held by the public reviewers, based on written and verbal comments that they have offered. The discussion begins with a short overview of the analytical assessment process most often used on DOE projects. The process is described in terms of the basic process elements and data sources involved. Based on this outline of the assessment process, the key elements from the public's perspective are identified and examined on the basis of Importance Criteria and the Perception Framework in which the Importance Criteria appear to be applied. The paper is concluded with an analysis of the key elements of the public's perception. This section of the discussion is formatted to couple observational evidence of public perception difficulties with key assessment elements, and these difficulties with potential alternative approaches that serve the same purpose but are more acceptable to the public

    Over the last three decades, NASA has been diligent in qualifying systems for human space flight. As the Agency transitions from operating the Space Shuttle, its employees must learn to accept higher risk levels to generate the data needed to certify its next human space flight system. The Marshall Center s Engineering workforce is developing the Ares I crew launch vehicle and designing the Ares V cargo launch vehicle for safety, reliability, and cost-effective operations. This presentation will provide a risk retrospective, using first-hand examples from the Delta Clipper-Experimental Advanced (DC-XA) and the X-33 single-stage-to-orbit flight demonstrators, while looking ahead to the upcoming Ares I-X uncrewed test flight. The DC-XA was successfully flown twice in 26 hours, setting a new turnaround-time record. Later, one of its 3 landing gears did not deploy, it tipped over, and was destroyed. During structural testing, the X-33 s advanced composite tanks were unable to withstand the forces to which it was subjected and the project was later cancelled. These are examples of successful failures, as the data generated are captured in databases used by vehicle designers today. More recently, the Ares I-X flight readiness review process was streamlined in keeping with the mission's objectives, since human lives are not at stake, which reflects the beginning of a cultural change. Failures are acceptable during testing, as they provide the lessons that actually lead to mission success. These and other examples will stimulate the discussion of when to accept risk in aerospace projects.

    We assessed the influence of the Fukushima nuclear accident (FNA) on the Chinese public's attitude and acceptance of nuclear power plants in China. Two surveys (before and after the FNA) were administered to separate subsamples of residents near the Tianwan nuclear power plant in Lianyungang, China. A structural equation model was constructed to describe the public acceptance of nuclear power and four risk perception factors: knowledge, perceived risk, benefit, and trust. Regression analysis was conducted to estimate the relationship between acceptance of nuclear power and the risk perception factors while controlling for demographic variables. Meanwhile, we assessed the median public acceptable frequencies for three levels of nuclear events. The FNA had a significant impact on risk perception of the Chinese public, especially on the factor of perceived risk, which increased from limited risk to great risk. Public acceptance of nuclear power decreased significantly after the FNA. The most sensitive groups include females, those not in public service, those with lower income, and those living close to the Tianwan nuclear power plant. Fifty percent of the survey respondents considered it acceptable to have a nuclear anomaly no more than once in 50 y. For nuclear incidents and serious incidents, the frequencies are once in 100 y and 150 y, respectively. The change in risk perception and acceptance may be attributed to the FNA. Decreased acceptance of nuclear power after the FNA among the Chinese public creates additional obstacles to further development of nuclear power in China and require effective communication strategies.

    A novel approach for establishing acceptability of risk is presented and illustrated by an application to the case of the light water reactors. The advantage of the method is that it takes into consideration the shape of the probability distribution function over consequences, instead of simply using the expected value of this distribution. 25 refs

    This paper focuses on the risk perception associated to the installation of low and intermediate level radioactive waste (LLRW and ILRW) disposal facilities. The purpose is to give support for the implementation of a repository in Brazil. Public acceptance results from a long term work and trust is vital for the process as it takes long to be conquered but might be shortly lost. Therefore, it is essential to care about the way each step is conducted. The knowledge about the system and the risks, the comprehension about these risks, the commitment with safety, adequate support systems for the project (legislation, involved institutions) and the excellence as a goal to be reached are extremely important parameters. The involvement of all interested parties in the decision-making process is condition for a successful and publicly acceptable implementation of such project. The steps for public acceptance of a repository are summarized as follow: Risk perception: to verify how the local population understand and feel the installation of a repository in the region. Media observatory: to continuously follow the news reaching the region where the repository will be installed, including different media. Local population social/economical/cultural profile identification: to determine the local population social/economical/cultural profile; to conduct a survey to know their expectations, allowing the proposal of compensation and incentives to fully account for their expectations. Finally, the philosophy governing this Project is: on doubt, the public must be heard and only after this public hearing the policies concerning the project shall be formulated. (author)

    In the wake of the 2011 Fukushima Daiichi Nuclear Power Station accident, to facilitate evidence-based risk communication we need to understand radiation risk perception and the effectiveness of risk-comparison information. We measured and characterized perceptions of dread risks and unknown risks regarding dietary radionuclides in residents of Fukushima, Tokyo, and Osaka to identify the primary factors among location, evacuation experience, gender, age, employment status, absence/presence of spouse, children and grandchildren, educational background, humanities/science courses, smoking habits, and various types of trustworthy information sources. We then evaluated the effects of these factors and risk-comparison information on multiple outcomes, including subjective and objective understanding, perceived magnitude of risk, perceived accuracy of information, backlash against information, and risk acceptance. We also assessed how risk-comparison information affected these multiple outcomes for people with high risk perception. Online questionnaires were completed by people (n = 9249) aged from 20 to 69 years in the three prefectures approximately 5 years after the accident. We gave each participant one of 15 combinations of numerical risk data and risk-comparison information, including information on standards, smoking-associated risk, and cancer risk, in accordance with Covello's guidelines. Dread-risk perception among Fukushima residents with no experience of evacuation was much lower than that in Osaka residents, whereas evacuees had strikingly higher dread-risk perception, irrespective of whether their evacuation had been compulsory or voluntary. We identified location (distance from the nuclear power station), evacuation experience, and trust of central government as primary factors. Location (including evacuation experience) and trust of central government were significantly associated with the multiple outcomes above. Only information on "cancer risk from

    Research has identified a number of risk factors for road traffic accidents. Some of these require education of drivers and a first step in this process is to assess perceptions of these risk factors to determine the current level of awareness. An online survey examined risk perception with the focus being on driver behavior, risk taking and fatigue. The results showed that drivers’ perceptions of the risk from being fatigued was lower than the perceived risk from the other factors.

    Examples are given of two types of comparative study that explore the sociocultural factors that shape public attitudes. In the first, public perceptions of nuclear power were assessed by answers to a questionnaire on a broad range of factors by 1500 people in France and the USA. A degree of homogeniety was observed in the responses from France and the USA. Strikingly, both populations agreed in their evaluation of the health risk represented by nuclear power plant. Thus the apparently greater acceptance of nuclear power in France does not seem to be associated with a lesser perception of risk. However, presented with the statement ``We can trust the experts and engineers who build, operate and regulate nuclear power`` 66% of the French agreed compared to only 43% of the Americans. These results reflect two different types of relationship between society and authority. In the second study the approach to gaining public trust and acceptance in the siting of nuclear waste research facilities was compared between the UK and France. Striking differences were found. In this case, too, an explanation can be put forward in terms of the sociocultural variables which influence institutional decision making, particularly in the role and form given to authority.

  10. Perception of risk and the future of nuclear power

    International Nuclear Information System (INIS)

    Slovic, P.

    1993-01-01

    Public support for nuclear power has declined greatly, driven by a number of powerful forces and events. Numerous studies have demonstrated the public's extreme perceptions of risk and negative attitudes regarding nuclear power. This negativity is remarkable in light of the confidence most technical analysts have regarding the safety of this technology. Public fears and opposition to nuclear power can be seen as a crisis in confidence, a profound breakdown in trust in the scientific, governmental, and industrial managers of nuclear technologies. The problem is not due to public ignorance or irrationality, but is deeply rooted in individual psychology and the adversarial nature of our social, institutional, legal, and political systems of risk management. In the absence of revolutionary changes in the ways that risks are managed in our society, it is unlikely that public trust, confidence, and acceptance of nuclear power can be regained

    Understanding and increasing awareness on individual risk for HIV infection as well as HIV risk perception's effects on different behavioral outcomes for people who inject drugs (PWID) is important for policymaking and planning purposes. The objectives of the present study were to determine whether HIV risk perception was associated with greater injection and sexual risk-taking behaviors among PWIDs. We surveyed 460 PWID in Kermanshah regarding their demographic characteristics, sexual risk behaviors, HIV risk perception, and drug-related risk behaviors in the month prior to the study. Three classes of HIV risk perception were identified using ordinal regression to determine factors associated with HIV risk perception. Study participants were categorized as follows: "low" (n = 100, 22%), "moderate" (n = 150, 32%), and "high" (n = 210, 46%) risk perception for becoming infected with HIV. The odds of categorizing as "high" risk for HIV was significantly greater in PWID that reported unprotected sex (adjusted odds ratio (AOR) 2.4, p value 0.02), receptive syringe sharing (AOR 1.8, p value 0.01), and multiple sex partners (AOR 1.4, p value 0.03). PWID who reported unprotected sex had 2.7 times the odds of "high" risk perception when compared to PWID with "low" risk perception. Findings show that PWID could rate their HIV risk with acceptable accuracy. Additionally, perceived HIV risk was associated with many risk factors for transmission of HIV, emphasizing the importance of developing targeted prevention and harm reduction programs for all domains of risk behaviors, both sexual and drug-related use.

    Full Text Available Introduction: The purpose of this paper is to assess if similar telemedicine services integrated in the management of different chronic diseases are acceptable and well perceived by patients or if there are any negative perceptions. Theory and methods: Participants suffering from different chronic diseases were enrolled in Veneto Region and gathered into clusters. Each cluster received a similar telemedicine service equipped with different disease-specific measuring devices. Participants were patients with diabetes (n = 163, chronic obstructive pulmonary disease (n = 180, congestive heart failure (n = 140 and Cardiac Implantable Electronic Devices (n = 1635. The Service User Technology Acceptability Questionnaire (SUTAQ was initially translated, culturally adapted and pretested and subsequently used to assess patients’ perception of telemedicine. Data were collected after 3 months and after 12 months from the beginning of the intervention. Data for patients with implantable devices was collected only at 12 months. Results: Results at 12 months for all clusters are similar and assessed a positive perception of telemedicine. The SUTAQ results for clusters 2 (diabetes, 5 (COPD and 7 (CHF after 3 months of intervention were confirmed after 12 months. Conclusions: Telemedicine was perceived as a viable addition to usual care. A positive perception for telemedicine services isn’t a transitory effect, but extends over the course of time.

    This study analyzes cattle farmers’ perceptions of risk and risk management strategies in Tigray, Northern Ethiopia. We use survey data from a sample of 356 farmers based on multistage random sampling. Factor analysis is employed to classify scores of risk and management strategies, and multiple...... utilization were perceived as the most important strategies for managing risks. Livestock disease and labor shortage were perceived as less of a risk by farmers who adopted the practice of zero grazing compared to other farmers, pointing to the potential of this practice for risk reduction. We find strong...... evidence that farmers engage in multiple risk management practices in order to reduce losses from cattle morbidity and mortality. The results suggest that government strategies that aim at reducing farmers’ risk need to be tailored to specific farm and farmer characteristics. Findings from this study have...

It tests the hypotheses that perceived risk to forest biodiversity is influenced by cognitive factors (value orientation and knowledge) and social-cultural factors (such as gender and environmental membership) and that risk perceptions influence other cognitive constructs such as support for natural resource policy and management. Data were collected from a sample of the general public (n= 596) in British Columbia, Canada by mail survey in 2001. Results show that insects and disease were perceived as the greatest risk. Educating the public and industry about biodiversity issues was perceived as a more effective conservation strategy than restricting human uses of the forest. Value orientation was a better predictor of perceptions of risk and perceived effectiveness of conservation strategies than knowledge indicators or social-cultural variables. Examining the indirect effects of social-cultural variables, however, revealed that value orientation may amplify the effect of these variables and suggests that alternative paths of influence should be included. Perceived risk showed an inconsistent association with perceived effectiveness of conservation strategies.

    Benefit and risk perception with respect to food consumption, have been a part of human daily life from beginning of time. In today's society the food chain is long with many different types of actors and low degree of transparency. Making informed food choices where knowledge of benefits and risks is part of the decision making process are therefore complicated for consumers. Thus, to understand how consumers perceive benefits and risks of foods, their importance in relation to quality evaluations are aspects that need to be addressed. The objective of this paper is to discuss state of the art in understanding consumer perceptions of benefits and risks of foods in order to improve understanding of consumer behaviour in the food domain. Risks may be associated with both acute and long term consequences, some of which may have serious effects. Perceived risks are connected to morbidity and mortality along two dimensions relating to unknown risk, and to which extent the risk is dreaded by the consumer. Unfamiliar, uncertain, unknown, uncontrollable, and severe consequences are some factors associated with risk perception. Novel food processing techniques, for instance, score high on several of these parameters and are consequently regarded with suspicion and perceived as risky by consumers. On a daily basis, benefits of foods and food consumption are more important in most consumers' minds than risks. Benefits are often associated with food's ability to assuage hunger, and to provide pleasure through eating and socialising. In addition, two main categories of benefits that are important for acceptance of product innovations are health and environmental benefits. Benefit and risk perception of foods seem to be inversely correlated, so when something is perceived as being highly beneficial, it is correspondingly perceived as having low risk. However, slightly different paths are used in the formation of these perceptions; benefit perception is based on heuristics and

    Background Subjective risk factor perception is an important component of the motivation to change unhealthy life styles. While prior studies assessed cardiovascular risk factor knowledge, little is known about determinants of the individual perception of stroke risk. Methods Survey by mailed questionnaire among 1483 participants of a prior public stroke campaign in Germany. Participants had been informed about their individual stroke risk based on the Framingham stroke risk score. Stroke risk factor knowledge, perception of lifetime stroke risk and risk factor status were included in the questionnaire, and the determinants of good risk factor knowledge and high stroke risk perception were identified using logistic regression models. Results Overall stroke risk factor knowledge was good with 67–96% of the participants recognizing established risk factors. The two exceptions were diabetes (recognized by 49%) and myocardial infarction (57%). Knowledge of a specific factor was superior among those affected by it. 13% of all participants considered themselves of having a high stroke risk, 55% indicated a moderate risk. All major risk factors contributed significantly to the perception of being at high stroke risk, but the effects of age, sex and education were non-significant. Poor self-rated health was additionally associated with high individual stroke risk perception. Conclusion Stroke risk factor knowledge was high in this study. The self perception of an increased stroke risk was associated with established risk factors as well as low perception of general health. PMID:17371603

    Risk perception is one of important subjects in management psychology and cognitive psychology. It is of great value in the theory and practice to investigate the societal hazards that the public cares a lot especially in Socio-economic transition period. A survey including 30 hazards and 6 risk attributes was designed and distributed to about 2, 485 residents of 8 districts, Beijing. The major findings are listed as following: Firstly, a scale of societal risk perception was designed and 2 factors were identified (Dread Risk & Unknown Risk). Secondly, structural equation model was used to analyze the influence factors and mechanism of societal risk perception. Risk preference, government support and social justice could influence societal risk perception directly. Government support fully moderated the relationship between government trust and societal risk perception. Societal risk perception influenced life satisfaction, public policy preferences and social development belief.

    2013-01-01

    Background In regions where access to clean water and the provision of a sanitary infrastructure has not been sustainable, cholera continues to pose an important public health burden. Although oral cholera vaccines (OCV) are effective means to complement classical cholera control efforts, still relatively little is known about their acceptability in targeted communities. Clarification of vaccine acceptability prior to the introduction of a new vaccine provides important information for future policy and planning. Methods In a cross-sectional study in Katanga province, Democratic Republic of Congo (DRC), local perceptions of cholera and anticipated acceptance of an OCV were investigated. A random sample of 360 unaffected adults from a rural town and a remote fishing island was interviewed in 2010. In-depth interviews with a purposive sample of key informants and focus-group discussions provided contextual information. Socio-cultural determinants of anticipated OCV acceptance were assessed with logistic regression. Results Most respondents perceived contaminated water (63%) and food (61%) as main causes of cholera. Vaccines (28%), health education (18%) and the provision of clean water (15%) were considered the most effective measures of cholera control. Anticipated vaccine acceptance reached 97% if an OCV would be provided for free. Cholera-specific knowledge of hygiene and self-help in form of praying for healing were positively associated with anticipated OCV acceptance if costs of USD 5 were assumed. Conversely, respondents who feared negative social implications of cholera were less likely to anticipate acceptance of OCVs. These fears were especially prominent among respondents who generated their income through fishing. With an increase of assumed costs to USD 10.5, fear of financial constraints was negatively associated with anticipated vaccine acceptance as well. Conclusions Results suggest a high motivation to use an OCV as long as it seems affordable. The

    The social and economic burden of diabetes is large and growing. Diabetes is a significant public health issue in the Appalachian region; women constitute approximately 50% of those diagnosed with diabetes. This cross-sectional study examined the relationship among sociodemographic, anthropometric, lifestyle, and psychosocial factors (cognitive and affective representations) and perceived risk of diabetes in non-diabetic, non-elderly (21-50 years) Appalachian women residing in West Virginia (N = 202). Participants were recruited through social media, flyers, and a newsletter from the West Virginia University Extension. The final survey was conducted from March 2015 to June 2015. Bivariate analyses were used to examine unadjusted relations among sociodemographic, anthropometric, lifestyle, and psychosocial factors and comparative perceived risk of diabetes. In a multivariable logistic regression model, we found that younger age, higher body mass index, non-White race, greater diabetes knowledge, personal control, and moderate amounts of physical activity were significantly, positively associated with higher diabetes risk perception (p related to diabetes risk perception among Appalachian women. Understanding perceived diabetes-related risk may aid in the development of effective intervention strategies to reduce the burden of diabetes among Appalachian and other populations. These cross-sectional findings need further evaluation in longitudinal studies.

  2. THE RISK PERCEPTION OF TRANSPORT–GENERATED AIR POLLUTION

    Full Text Available This paper describes a study that is part of a multidisciplinary project examining the relationship between transport, air pollution and health in Guildford, a medium sized town in the UK. Real-time air quality monitoring revealed low levels of air pollution through vehicle emissions. However, the residents of the town claim that there is an air pollution problem, perceptions reinforced by visual and sensory feedback, i.e., people see dust, feel irritations to their eyes, noses and throats and smell exhaust fumes. It is shown that the higher people believe air pollution levels to be the more responsible they feel and the less trust they have in local authorities and technological developments. Beliefs about the health consequences of air pollution are not related to responsibility and trust. The findings support other studies on risk perception that have shown that people find a risk less acceptable when they have a lower trust in risk managers. It is concluded that these findings are of importance for the environmental education of the public generally and risk communication by local authorities in particular.

    The purpose of the study was to describe perception of risk for developing diabetes among foreign-born Spanish-speaking US Latinos. Participants (N = 146), recruited at food-pantry distribution events and free clinics, were surveyed using the Risk Perception Survey for Developing Diabetes in Spanish. Type 2 diabetes risk factors measured included body mass index, physical activity, and A1C. Sample characteristics were mean (SD) age of 39.5 (9.9) years, 58% with less than a high school graduate-level education, and 65% with a family income less than $15,000/year. Prevalence of risk factors was 81% overweight or obese, 47% less than 150 minutes/week moderate/vigorous-intensity physical activity, and 12% A1C consistent with prediabetes. Of the 135 participants with complete data, 31% perceived a high/moderate risk for developing diabetes. In univariate logistic regression analyses, 9 of 18 potential variables were significant (P perception of risk. When these 9 variables were entered into a multiple logistic regression model, 5 were significant predictors of perception of risk: history of gestational diabetes, high school graduate or above, optimistic bias, worry, and perceived personal disease risk. Use of the Spanish-language translation of the Risk Perception Survey for Developing Diabetes revealed factors influencing perception of risk for developing diabetes. Results can be used to promote culturally acceptable type 2 diabetes primary prevention strategies and provide a useful comparison to other populations. © 2016 The Author(s).

  4. A proposed risk acceptance criterion for nuclear fuel waste disposal

    International Nuclear Information System (INIS)

    Mehta, K.

    1985-06-01

    The need to establish a radiological protection criterion that applies specifically to disposal of high level nuclear fuel wastes arises from the difficulty of applying the present ICRP recommendations. These recommendations apply to situations in which radiological detriment can be actively controlled, while a permanent waste disposal facility is meant to operate without the need for corrective actions. Also, the risks associated with waste disposal depend on events and processes that have various probabilities of occurrence. In these circumstances, it is not suitable to apply standards that are based on a single dose limit as in the present ICRP recommendations, because it will generally be possible to envisage events, perhaps rare, that would lead to doses above any selected limit. To overcome these difficulties, it is proposed to base a criterion for acceptability on a set of dose values and corresponding limiting values of probabilities; this set of values constitutes a risk-limit line. A risk-limit line suitable for waste disposal is proposed that has characteristics consistent with the basic philosophy of the ICRP and UNSCEAR recommendations, and is based on levels on natural background radiation

  5. Understanding and acknowledging the ice throw hazard - consequences for regulatory frameworks, risk perception and risk communication

    This study attempts to provide the necessary framework required to make sufficiently informed decisions regarding the safety implications of ice throw. The framework elaborates on how to cope with uncertainties, and how to describe results in a meaningful and useful manner to decision makers. Moreover, it points out the moral, judicial and economical obligations of wind turbine owners such that they are able to minimize risk of ice throws as much as possible. Building on the strength of knowledge as well as accounting for uncertainty are also essential in enabling clear communication with stakeholders on the most important/critical/vital issues. With increasing empirical evidence, one can assign a higher confidence level on the expert opinions on safety. Findings regarding key uncertainties of ice risk assessments are presented here to support the ongoing IEA Wind Task 19's work on creating the international guidelines on ice risk assessment due in 2018 (Krenn et al. 2017)[1-6]. In addition the study also incorporates the findings of a Norwegian information project, which focuses on the ice throw hazard for the public (Bredesen, Flage, Butt, Winterwind 2018)[7-9]. This includes measures to reduce damage and hazard from wind turbines for the general public. Recent theory of risk assessment questions the use of risk criteria for achieving optimum risk reduction and favours the use of the ALARA (as low as reasonably achievable) principle. Given the several practical problems associated with the ALARA approach (e.g. judicial realization), a joint approach, which uses a minimum set of criteria as well as the obligation to meet ALARA is suggested (associated with acceptable cost). The actual decision about acceptance criteria or obligations is a societal one, thus suggestions can be made at best. Risk acceptance, risk perception and risk communication are inextricably linked and should thus never be considered separately. Risk communication can shape risk perception

    The evaluation, application, and risk acceptance for realistic minimum accident source terms can represent a complex and arduous undertaking. This effort poses a very high impact to design, construction cost, operations and maintenance, and integrated safety over the expected facility lifetime. At the 2005 Nuclear Criticality Safety Division (NCSD) Meeting in Knoxville Tenn., two papers were presented mat summarized the Y-12 effort that reduced the number of criticality accident alarm system (CAAS) detectors originally designed for the new Highly Enriched Uranium Materials Facility (HEUMF) from 258 to an eventual as-built number of 60. Part of that effort relied on determining a realistic minimum accident source term specific to the facility. Since that time, the rationale for an alternate minimum accident has been strengthened by an evaluation process that incorporates realism. A recent update to the HEUMF CAAS technical basis highlights the concepts presented here. (authors)

  7. Psychological Factors Linked to Risk Perception

    Risks are mental models, which allow people to cope with dangerous phenomena (Renn, 2008; Jasanoff, 1998). The term "risk" refers to the likelihood of an adverse effect resulting from an event. The aim of the present study is to identify the psychological factors that are most predictive of risk perception in relation with age, gender, educational level and socio-economical status. Earthquake hazard was considered, because it is an emerging danger for Bucharest. 80% of the laypeople sample are waiting for this event to happen in the next three years. By integrating all the research data, it was attempted to build a risk profile of the investigated population, which could be used by institutions responsible for earthquake risk mitigation situations in Bucharest. This research appealed to the social learning Rotter (1966), auto-effectiveness Bandura (1977; 1983), and anxiety and stress theories. We used psychological variables that measured stress, personal effectiveness and the belief in personal control. The multi-modal risk perception questionnaire was structured on a 49 items sequence. The sample was composed of 1.376 participants recruited on a voluntary basis. The characteristics of risk (like probability and magnitude, time scales) are perceived differently according to psychological factors that play a role also in biases in people's ability to draw inferences from probabilistic information (like cognitive dissonance). Since the 1970's, it has been argued that those who perceive life's events as being beyond their locus of control (external locus of control) are significantly more anxious and less adapted. In this research, strongest associations and significant differences were obtained between sex, age and income categories with Stress vulnerability factor and the External Locus of Control factor. The profile of the low risk perceiver is that of a young, more educated, male individual with a higher self- efficacy level and an internal locus of control.

    There is a growing body of research linking children’s positively biased self-perceptions with higher levels of aggression. This study extended this area of research by examining prospective associations of positively biased self-perceptions of peer acceptance with overt and relational aggression. In addition, moderating effects of peer rejection were examined to test the “disputed overestimation hypothesis,” which posits that the link between bias and aggression is limited to children who are rejected by their peers. Using a two-wave longitudinal design, measures of peer-rated and self-perceived peer acceptance and peer-rated overt and relational aggression were obtained for 712 children in 3rd through 5th grades (386 girls and 326 boys). Positively biased perceptions led to increases in relational, but not overt, aggression. This pattern was observed even when the effects of gender, race, peer rejection, and overt aggression on relational aggression were controlled. Contrary to the disputed overestimation hypothesis, the prospective associations between bias and aggression did not vary as a function of children’s peer rejection status, thus supporting the view that positive bias predicts future aggressive behavior, regardless of social status. The results are discussed in terms of the comparability with previous findings and practical implications. PMID:26423823

  9. Why does society accept a higher risk for alcohol than for other voluntary or involuntary risks?

    Science.gov (United States)

    Rehm, Jürgen; Lachenmeier, Dirk W; Room, Robin

    2014-10-21

    Societies tend to accept much higher risks for voluntary behaviours, those based on individual decisions (for example, to smoke, to consume alcohol, or to ski), than for involuntary exposure such as exposure to risks in soil, drinking water or air. In high-income societies, an acceptable risk to those voluntarily engaging in a risky behaviour seems to be about one death in 1,000 on a lifetime basis. However, drinking more than 20 g pure alcohol per day over an adult lifetime exceeds a threshold of one in 100 deaths, based on a calculation from World Health Organization data of the odds in six European countries of dying from alcohol-attributable causes at different levels of drinking. The voluntary mortality risk of alcohol consumption exceeds the risks of other lifestyle risk factors. In addition, evidence shows that the involuntary risks resulting from customary alcohol consumption far exceed the acceptable threshold for other involuntary risks (such as those established by the World Health Organization or national environmental agencies), and would be judged as not acceptable. Alcohol's exceptional status reflects vagaries of history, which have so far resulted in alcohol being exempted from key food legislation (no labelling of ingredients and nutritional information) and from international conventions governing all other psychoactive substances (both legal and illegal). This is along with special treatment of alcohol in the public health field, in part reflecting overestimation of its beneficial effect on ischaemic disease when consumed in moderation. A much higher mortality risk from alcohol than from other risk factors is currently accepted by high income countries.

    Kurzenhäuser, S; Epp, A

    2009-12-01

    This article reviews central findings and current developments of psychological and sociological research on the perception of health risks. Risk perception is influenced by numerous psychological, social, political, and cultural factors. These factors can be categorized into (a) risk characteristics, (b) characteristics of the risk perceiving person and his/her situation, and (c) characteristics of risk communication. Thus, besides individual cognitive and affective processing of risk information, social processes of risk amplification (e.g., media effects) are also involved in the construction of individual risk perceptions. We discuss the recommendations for health risk communication that follow from these findings with regard to different communication goals.

    The focus of this paper is on changes in perceptions of the risks associated with nuclear waste management over time. In particular, we are interested in the kinds of change that take place when the management programs, and those who are charged with implementing them, are subject to intensive public debate over an extended period of time. We are undertaken an over-time study of perceived risks in Colorado and New Mexico by implementing sequential random household surveys in each state, timed at six month intervals. This study employs three of these surveys, spanning the period from summer, 1990 to summer, 1991. Using these data, we examine the dynamics that may underlie variations in perceived risks over time. In particular, our analysis is focused on changes in the roles played by (1) basic political orientations (i.e. political ideology) and (2) trust in those who advocate conflicting policy positions

For such a subtle task, it will be good to know something about the person, who undertakes such a challenge. Thus, he first makes a short description of himself in a number of relevant personal feature, emphasising rather what he is not: cadre of insurance company.... etc. He starts with a literal understanding of the idiom Risk Perception in English and in other languages (in Chinese). This formulation, still abstract, is framed with concrete objects, and materialised into touchable structures. He then puts life into these structures, and makes them accessible to emotion and experience. Now that this notion is animated, he follows it's way into life in the field of Radiation Protection, and find among others that the term Cost and Benefit correspond to the Chinese idiom, and that the system of Justification and Optimisation is as difficult to achieve objectively as an Upright Walk on the Confucian Path to-ward the Middle. One of the difficulties lies in the difference in the scale in estimating values. For instance, though the idea of Asian and Western Values are rather diffuse, their difference is never-the-less high enough to render it to be insurmountable, at least at present. These observation belong actually to common experience of Health physicists, and nothing new or spectacular is presented. The author emphasises only, again not a new idea of his own, only putting weight to, that perception depends on point of view, or rather on stand of viewing points, and rarely represent the whole story, the true situation. This leads, according to the author, to the well known and accepted term of Risk Residuum, in German, Rest Risiko. Despite of partialness of all perceptions, solid decisions are based on perception.

    Uncertainty provides opportunities for differences in perception, and radiation risks at low level of exposures involved in few computed tomography scans fall in this category. While there is good agreement among national and international organisations on risk probability of cancer, risk perception has barely been dealt with by these organisations. Risk perception is commonly defined as the subjective judgment that people make about the characteristics and severity of a risk. Severity and latency are important factors in perception. There is a need to connect all these. Leaving risk perception purely as a subjective judgement provides opportunities for people to amplifying risk. The author postulates a risk perception index as severity divided by latency that becomes determining factor for risk perception. It is hoped that this index will bring rationality in risk perception. (authors)

    Vector and malaria parasite's rising resistance against pyrethroid-impregnated bed nets and antimalarial drugs highlight the need for additional control measures. Larviciding against malaria vectors is experiencing a renaissance with the availability of environmentally friendly and target species-specific larvicides. In this study, we analyse the perception and acceptability of spraying surface water collections with the biological larvicide Bacillus thuringiensis israelensis in a single health district in Burkina Faso. A total of 12 focus group discussions and 12 key informant interviews were performed in 10 rural villages provided with coverage of various larvicide treatments (all breeding sites treated, the most productive breeding sites treated, and untreated control). Respondents' knowledge about the major risk factors for malaria transmission was generally good. Most interviewees stated they performed personal protective measures against vector mosquitoes including the use of bed nets and sometimes mosquito coils and traditional repellents. The acceptance of larviciding in and around the villages was high and the majority of respondents reported a relief in mosquito nuisance and malarial episodes. There was high interest in the project and demand for future continuation. This study showed that larviciding interventions received positive resonance from the population. People showed a willingness to be involved and financially support the program. The positive environment with high acceptance for larviciding programs would facilitate routine implementation. An essential factor for the future success of such programs would be inclusion in regional or national malaria control guidelines.

  18. The Psychology of Hazard Risk Perception

    Thompson, K. F.

    2012-12-01

    A critical step in preparing for natural hazards is understanding the risk: what is the hazard, its likelihood and range of impacts, and what are the vulnerabilities of the community? Any hazard forecast naturally includes a degree of uncertainty, and often these uncertainties are expressed in terms of probabilities. There is often a strong understanding of probability among the physical scientists and emergency managers who create hazard forecasts and issue watches, warnings, and evacuation orders, and often such experts expect similar levels of risk fluency among the general public—indeed, the Working Group on California Earthquake Probabilities (WGCEP) states in the introduction to its earthquake rupture forecast maps that "In daily living, people are used to making decisions based on probabilities—from the flip of a coin (50% probability of heads) to weather forecasts (such as a 30% chance of rain) to the annual chance of being killed by lightning (about 0.0003%)." [1] However, cognitive psychologists have shown in numerous studies [see, e.g., 2-5] that the WGCEP's expectation of probability literacy is inaccurate. People neglect, distort, misjudge, or misuse probability information, even when given strong guidelines about the meaning of numerical or verbally stated probabilities [6]. Even the most ubiquitous of probabilistic information—weather forecasts—are systematically misinterpreted [7]. So while disaster risk analysis and assessment is undoubtedly a critical step in public preparedness and hazard mitigation plans, it is equally important that scientists and practitioners understand the common psychological barriers to accurate probability perception before they attempt to communicate hazard risks to the public. This paper discusses several common, systematic distortions in probability perception and use, including: the influence of personal experience on use of statistical information; temporal discounting and construal level theory; the effect

    Understanding public perceptions of climate change risks is a prerequisite for effective climate communication and adaptation. Many studies of climate risk perceptions have either analyzed a general operationalization of climate change risk or employed a case-study approach of specific adaptive processes. This study takes a different approach, examining attitudes toward 17 specific, climate-related coastal risks and cognitive, affective, and risk-specific predictors of risk perception. A survey of 558 undergraduates revealed that risks to the physical environment were a greater concern than economic or biological risks. Perceptions of greater physical environment risks were significantly associated with having more pro-environmental attitudes, being female, and being more Democratic-leaning. Perceptions of greater economic risks were significantly associated with having more negative environmental attitudes, being female, and being more Republican-leaning. Perceptions of greater biological risks were significantly associated with more positive environmental attitudes. The findings suggest that focusing on physical environment risks maybe more salient to this audience than communications about general climate change adaptation. The results demonstrate that climate change beliefs and risk perceptions are multifactorial and complex and are shaped by individuals' attitudes and basic beliefs. Climate risk communications need to apply this knowledge to better target cognitive and affective processes of specific audiences, rather than providing simple characterizations of risks.

    Full Text Available This paper presents an empirical study aiming on investigating ODL students’ perception and adoption of SCORM Compliant Learning Object (SCLO. With the increasing use of SCLO in recent years, a better understanding and implementation of effective instructional resources is necessary to meet the diverse needs of ODL students and enhance their learning performance. The eventual usage of relevant stakeholders determines the success of a system. The system is useless if it is not used in the expected way by the potential users even though it is a good system. Therefore, the aim of this research is to examine if ODL students will eventually use SCLO for their learning. The study used TAM as a basis to investigate the relationship of external and internal variables. A survey instrument eliciting responses on a series of Likert-type questions was given to selected ODL undergraduate students. The results of this study confirm that users’ perception has significant effect on the acceptance and adoption of SCLO. The study provides a better understanding of students’ behavior on SCLO and the acceptance model.

    The current study investigated how adolescents perceive their own health risks and compare their own likelihood of health risks with that of others of the same age. Moreover, the study identified the differences in health risk perceptions between males and females. A total of 625 adolescents (314 males and 311 females) from the Nowon district, geographically located in northern Seoul, voluntarily participated. In order to measure health risk perceptions a Korean version of self-other risk judgments profile was used. The findings indicated that study participants, regardless of gender and age, tend to underestimate their vulnerability to majority of health risk events. Furthermore, there were significant gender and age differences in health risk perception and perception bias in all health risk domains. The present study suggests that further research is needed to identify realistic and unrealistic perception mechanism for a large number of people from different demographic and socioeconomic backgrounds.

    This is an exploratory study carrying out qualitative research into the perceptions, attitudes and concerns of elderly persons towards wireless sensor network (WSN) technologies in terms of their application to healthcare. This work aims to provide guidance on the dimensions and items that may be included in the development of a more in-depth questionnaire to further validate the importance of the identified factors as well as the relationships between them. This study aims to contribute to opening up a communication channel between users and researchers, informing the research community in relation to applications and functionalities that users deem as either desirable, inadequate or in need of further development. Focus groups were conducted with elderly individuals who were still living independently. To explore elderly persons' perceptions and thoughts on current wireless sensor network (WSN) technologies and designs, discussion points were designed from concepts identified from various user acceptance theories and models. Participants were given an introduction to explain the functionality and capabilities of WSN and motes and were shown a sample mote, the Crossbow Mica2Dot. Participants were then asked to discuss their perceptions and concerns towards the likelihood of using a WSN-based healthcare system in their home. We have identified sixteen concepts in relation to the elderly participants' perception, concerns and attitudes towards WSN systems. Those concepts were further classified into six themes describing the determinants that may affect an elderly person's acceptance of WSNs for assisting healthcare. Some of our exploratory findings in this study indicate for example that independence is highly valued by elderly people and hence any system or technology that can prolong that independence tends to be highly regarded, that privacy of WSN health data might not be as important as typically considered, and there are also indications that cost may be the

    Santorini, Greece is a major explosive volcano. The Santorini volcanic complex is composed of two active volcanoes—Nea Kameni and Mt. Columbo. Holocene eruptions have generated a variety of processes and deposits and eruption mechanisms pose significant hazards of various types. It has been recognized that, for major European volcanoes, few studies have focused on the social aspects of volcanic activity and little work has been conducted on public perceptions of hazard, risk and vulnerability. Such assessments are an important element of establishing public education programmes and developing volcano disaster management plans. We investigate perceptions of volcanic hazards on Santorini. We find that most residents know that Nea Kameni is active, but only 60% know that Mt. Columbo is active. Forty percent of residents fear that negative impacts on tourism will have the greatest effect on their community. In the event of an eruption, 43% of residents would try to evacuate the island by plane/ferry. Residents aged >50 have retained a memory of the effects of the last eruption at the island, whereas younger residents have no such knowledge. We find that dignitaries and municipal officers (those responsible for planning and managing disaster response) are informed about the history, hazards and effects of the volcanoes. However, there is no "emergency plan" for the island and there is confusion between various departments (Civil Defense, Fire, Police, etc.) about the emergency decision-making process. The resident population of Santorini is at high risk from the hazards associated with a future eruption.

    In a food exhibition where several producers of the same product category are present at the same time, consumers usually have the opportunity to taste several free samples of the same product type, thus they can experience and compare the sensory characteristics of each and evaluate their liking for each sample tasted. This study assessed the potential of an itinerant sensory data collection in understanding the consumers' perception and acceptance of cheese during a multiple tasting experience at a food exhibition. Subjects tasted seven samples of Parmigiano Reggiano cheese aged for different times (24 and 36months) at seven producer stands and recorded their evaluations using tablets, on which an application specifically developed for this study was installed. This evaluation situation was defined as "pseudo-natural," in opposition to the "natural" and the "naturalistic" settings. The itinerant sensory session comprised a liking test, a rate-all-that-apply (RATA) test using a just about right (JAR) scale, a food pairing test, and a questionnaire. Consumers significantly (panalysis, and decision tree models in investigating the relationships between liking and the RATA data, provided results revealing that the attributes elasticity, sweetness, humidity, fresh fruit, and butter were the main drivers of liking. Whereas, the attributes sourness, bitterness, and hardness were the main drivers of dislike. Therefore, even though no significant differences in terms of liking were observed among the tested cheeses, consumers preferred the attributes more frequently perceived in the least aged products. In conclusion, the presented itinerant sensory approach had provided meaningful information to understand the consumers' cheese perception and acceptability. In the future, it could advantageously be applied for studying food perception in other situations in which subjects naturally choose or consume several products while freely moving from one to another (e.g. self

    Wong, Catherine Mei Ling

    2015-11-01

    This article focuses on the fluid nature of risk problems and the challenges it presents to establishing acceptability in risk governance. It introduces an actor-network theory (ANT) perspective as a way to deal with the mutable nature of risk controversies and the configuration of stakeholders. To translate this into a practicable framework, the article proposes a hybrid risk governance framework that combines ANT with integrative risk governance, deliberative democracy, and responsive regulation. This addresses a number of the limitations in existing risk governance models, including: (1) the lack of more substantive public participation throughout the lifecycle of a project; (2) hijacking of deliberative forums by particular groups; and (3) the treatment of risk problems and their associated stakeholders as immutable entities. The framework constitutes a five-stage process of co-selection, co-design, co-planning, and co-regulation to facilitate the co-production of collective interests and knowledge, build capacities, and strengthen accountability in the process. The aims of this article are twofold: conceptually, it introduces a framework of risk governance that accounts for the mutable nature of risk problems and configuration of stakeholders. In practice, this article offers risk managers and practitioners of risk governance a set of procedures with which to operationalize this conceptual approach to risk and stakeholder engagement. © 2015 Society for Risk Analysis.

    Although there are current efforts to integrate herbal medicine (HM) into mainstream healthcare in Ghana, there is paucity of empirical evidence on the acceptability and concurrent use of HM, in the formal health facilities in Ghana. This study sought to determine client perception, disclosure and acceptability of integrating herbal medicine in mainstream healthcare in Kumasi, Ghana. A cross-sectional study was conducted from May to August, 2015. Five hundred patients presenting at the outpatient departments of Kumasi South, Suntreso and Tafo Government Hospitals in Kumasi were randomly selected. Interviews were conducted with the use of structured questionnaires. A logistic regression analysis, using backward selection, was conducted to determine the influence of socio-demographic and facility related factors on the odds of using HM at the facility. All statistical tests were two-sided and considered significant at a p-value of herbal medicines. Respondents who rated themselves wealthy had increased odds of using herbal medicines at the health facility as compared to those who rated themselves poor (OR = 4.9; 95%CI = 1.6-15.3). This study shows that integration of herbal medicine is feasible and herbal medicines may be generally accepted as a formal source of healthcare in Ghana. The results of this study might serve as a basis for improvement and upscale of the herbal medicine integration programme in Ghana.

    Adolescence is a period of life in which peer relationships become increasingly important. Adolescents have a greater likelihood of taking risks when they are with peers rather than alone. In this study, we investigated the development of social influence on risk perception from late childhood through adulthood. Five hundred and sixty-three participants rated the riskiness of everyday situations and were then informed about the ratings of a social-influence group (teenagers or adults) before rating each situation again. All age groups showed a significant social-influence effect, changing their risk ratings in the direction of the provided ratings; this social-influence effect decreased with age. Most age groups adjusted their ratings more to conform to the ratings of the adult social-influence group than to the ratings of the teenager social-influence group. Only young adolescents were more strongly influenced by the teenager social-influence group than they were by the adult social-influence group, which suggests that to early adolescents, the opinions of other teenagers about risk matter more than the opinions of adults. © The Author(s) 2015.

Generic medicines provide the same therapeutic outcomes but at a much cheaper cost, so are promoted in many countries to contain pharmaceutical expenditure and sustain the health care system. Thus, the perspective of patients and medicine consumers as end users of these medicines is an important factor to enhance the use and utilization of generic medicines. The objective of this paper is to review patients’ and consumers’ knowledge, perceptions, acceptance, and views of generic medicines in the current literature. Methods: An extensive literature search was performed in several databases, namely Scopus, PubMed, ISI Web of Knowledge, Proquest, and the Wiley online library, to identify relevant studies published in the English literature for the period 1990–2013. Results: A total of 53 studies were included in the review, comprising 24 studies from Europe, ten from North America, six from Asia, five from Australia and New Zealand, five from the Middle East, one from Africa, one from Latin America, and one from the Caribbean region. A large body of literature has reported misconceptions and negative perceptions about generic medicines on the part of patients and medicine consumers. Moreover, although it is reported in almost all countries, the percentage of consumers who had

    One of the most important concerns of the postindustrial societies lies on the specification and quantification of risk, the Risk Assesment. However, the efforts and resources devoted to such goal have not avoided a growing worry about both the environmental conditions and the situations that potentially threaten it, generating an intense social debate about risks. In this framework, discrepancies between experts and public evaluations risks leaded to the study of social Risk perception. Several theoretical scopes have tried to characterize the phenomenon. A worthy conclusion of the empirical studies carried out on this issue is that all of them, experts and public, are influence by some factors which, in turns, affect their risk perception,. Specially striking is the fact that perception of risk among experts is also modulated by qualitative, personal and social factors. Social Risk Perception, through the process of Communication and Social Participation, has been configurated as a critical tool for both risk prevention and management

  14. Exposure Knowledge and Risk Perception of RF EMF

    The presented study is part of the EU-Project Low EMF Exposure Future Networks (LEXNET), which deals among other things with the issue of whether a reduction of the radiofrequency (RF) electro-magnetic fields (EMF) exposure will result in more acceptance of wireless communication networks in the public sphere. We assume that the effects of any reduction of EMF exposure will depend on the subjective link between exposure perception and risk perception (RP). Therefore we evaluated respondents’ RP of different RF EMF sources and their subjective knowledge about various exposure characteristics with regard to their impact on potential health risks. The results show that participants are more concerned about base stations than about all other RF EMF sources. Concerning the subjective exposure knowledge the results suggest that people have a quite appropriate impact model. The question how RF EMF RP is actually affected by the knowledge about the various exposure characteristics was tested in a linear regression analysis. The regression indicates that these features – except distance – do influence people’s general RF EMF RP. In addition, we analyzed the effect of the quality of exposure knowledge on RF EMF RP of various sources. The results show a tendency that better exposure knowledge leads to higher RP, especially for mobile phones. The study provides empirical support for models of the relationships between exposure perception and RP. It is not the aim to extrapolate these findings to the whole population because the samples are not exactly representative for the general public in the participating countries. PMID:25629026

  15. Safety targets and public risk perceptions in the nuclear field - technical treadmill or institutional responses?

    International Nuclear Information System (INIS)

    Wynne, B.

    1989-01-01

    The context of our treatment of risk perceptions and safety targets is the apparently wide gap between expert judgements of 'objective risks' and public perceptions of those risks. In the nuclear field the latter appear to so multiply the objective risks as seen by the experts, as to make safety targets vastly too strict (whether for routine discharges or for large accidents), thus design extravagantly expensive on any 'rational' criteria. In recent years the nuclear industry has come to terms more with the public perceptions problem, and has accepted that it is legitimate to exercise different, more severe and costly safety standards in the nuclear field if that is what society wants, as it appears to do. Whilst retaining the conviction that this is scientifically unwarranted, the industry has therefore reconciled itself somewhat to more stringent technical safety targets. (author)

    We examined event-contingent recording of daily interpersonal interactions in a diagnostically diverse sample of 101 psychiatric outpatients who were involved in a romantic relationship. We tested whether the unique effect of borderline personality disorder (BPD) symptoms on affective responses (i.e., hostility, sadness, guilt, fear, and positive affect) to perceptions of rejection or acceptance differed with one's romantic partner compared with nonromantic partners. BPD symptoms were associated with more frequent perceptions of rejection and less frequent perceptions of acceptance across the study. For all participants, perceptions of rejecting behavior were associated with higher within-person negative affect and lower within-person positive affect. As predicted, in interactions with romantic partners only, those with high BPD symptoms reported heightened hostility and, to a lesser extent, attenuated sadness in response to perceptions of rejection. BPD symptoms did not moderate associations between perceptions of rejection and guilt, fear, or positive affect across romantic and nonromantic partners. For all participants, perceived acceptance was associated with lower within-person negative affect and higher within-person positive affect. However, BPD symptoms were associated with attenuated positive affect in response to perceptions of accepting behavior in interactions with romantic partners only. BPD symptoms did not moderate associations between perceptions of acceptance and any of the negative affects across romantic and nonromantic partners. This study highlights the specificity of affective responses characteristic of BPD when comparisons are made with patients with other personality and psychiatric disorders. Implications for romantic relationship dysfunction are discussed. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

    In this article, we present the results of a study investigating the influence of vulnerability to climate change as a function of physical vulnerability, sensitivity, and adaptive capacity on climate change risk perception. In 2008/2009, we surveyed Nevada ranchers and farmers to assess their climate change-related beliefs, and risk perceptions, political orientations, and socioeconomic characteristics. Ranchers' and farmers' sensitivity to climate change was measured through estimating the proportion of their household income originating from highly scarce water-dependent agriculture to the total income. Adaptive capacity was measured as a combination of the Social Status Index and the Poverty Index. Utilizing water availability and use, and population distribution GIS databases; we assessed water resource vulnerability in Nevada by zip code as an indicator of physical vulnerability to climate change. We performed correlation tests and multiple regression analyses to examine the impact of vulnerability and its three distinct components on risk perception. We find that vulnerability is not a significant determinant of risk perception. Physical vulnerability alone also does not impact risk perception. Both sensitivity and adaptive capacity increase risk perception. While age is not a significant determinant of it, gender plays an important role in shaping risk perception. Yet, general beliefs such as political orientations and climate change-specific beliefs such as believing in the anthropogenic causes of climate change and connecting the locally observed impacts (in this case drought) to climate change are the most prominent determinants of risk perception. © 2012 Society for Risk Analysis.

    This paper discusses the concept of sustainability in relation to acceptance of nuclear energy. Acceptance is viewed in terms of public acceptance, industrial acceptance, and internal acceptance/consensus within the nuclear community. It addresses sustainability criteria, the need for innovation, and the different levels of acceptability. The mechanisms of risk perception are discussed along with the technological consequences from risk perception mechanisms leading to specific objections against nuclear energy. (author)

    The research was carried out in the city center of the coastal community of Arauco, Central Chile. The community of Arauco was one of the most affected communities of the tsunami in Chile, the 27th of February 2010. For the data evaluation, the affected inhabitants of the community have been surveyed via standardized questionnaires. Furthermore experts of different fields, amongst others, Disaster Risk Management (DRM), risk education, urban and regional planning, as well as geology have been consulted in form of expert interviews. The results revealed a high risk perception part of the affected community and a weakness of DRM especially at local level, which opens a gap between the evaluation and treatment of risk by experts and risk perception of the affected community. The risk perception of the affected community, here, is predominantly determined by ecological vulnerability, expressed in direct and indirect experience of a tsunami and by institutional vulnerability, expressed among others by a weakness of DRM at local level and a mistrust in responsible institutions for DRM. Due to the institutional vulnerability and the mistrust in responsible institutions we recommend a Community Based Approach (CBA) to strengthen DRM at local level and to take advantage of the high risk perception and knowledge of the affected community. Involving the community in DRM, we assume to close the gap between risk evaluation of experts and risk perception of the inhabitants and to come up with the unique necessities and conditions at local level. Especially in centralized countries, DRM is less effective, because at the one hand, decisions are made distant from the affected communities, so that measures often do not come up with the unique conditions and necessities at local level, and on the other hand measures often do not find acceptance by the affected community. Furthermore centralized DRM is often not effective and quick in response in case of emergency. Another obstacle

    In evaluation of safety in projects it is common to use risk acceptance criteria to support decision-making. In this paper, we discuss to what extent the risk acceptance criteria is in accordance with the normative theoretical framework of the expected utility theory and the rank-dependent utility theory. We show that the use of risk acceptance criteria may violate the independence axiom of the expected utility theory and the comonotonic independence axiom of the rank-dependent utility theory. Hence the use of risk acceptance criteria is not in general consistent with these theories. The level of inconsistency is highest for the expected utility theory.

    2013-01-01

    Background Online mental health resources have been proposed as an innovative means of overcoming barriers to accessing rural mental health services. However, clinicians tend to express lower satisfaction with online mental health resources than do clients. Objective To understand rural clinicians’ attitudes towards the acceptability of online mental health resources as a treatment option in the rural context. Methods In-depth interviews were conducted with 21 rural clinicians (general practitioners, psychologists, psychiatrists, and clinical social workers). Interviews were supplemented with rural-specific vignettes, which described clinical scenarios in which referral to online mental health resources might be considered. Symbolic interactionism was used as the theoretical framework for the study, and interview transcripts were thematically analyzed using a constant comparative method. Results Clinicians were optimistic about the use of online mental health resources into the future, showing a preference for integration alongside existing services, and use as an adjunct rather than an alternative to traditional approaches. Key themes identified included perceptions of resources, clinician factors, client factors, and the rural and remote context. Clinicians favored resources that were user-friendly and could be integrated into their clinical practice. Barriers to use included a lack of time to explore resources, difficulty accessing training in the rural environment, and concerns about the lack of feedback from clients. Social pressure exerted within professional clinical networks contributed to a cautious approach to referring clients to online resources. Conclusions Successful implementation of online mental health resources in the rural context requires attention to clinician perceptions of acceptability. Promotion of online mental health resources to rural clinicians should include information about resource effectiveness, enable integration with existing

    Public risk perceptions of mass disasters carry considerable influences, both psychologically and economically, despite their oft-times imprecise nature. Prior research has identified the presence of an optimistic bias that affects risk perception, but there is a dearth of literature examining how these perceptions differ among cultures-particularly with regard to mass disasters. The present study explores differences among Japanese, Argentinean, and North American mental health workers in their rates of the optimistic bias in risk perceptions as contrasted between natural disasters and terrorist events. The results indicate a significant difference among cultures in levels of perceived risk that do not correspond to actual exposure rates. Japanese groups had the highest risk perceptions for both types of hazards and North Americans and Argentineans had the lowest risk perceptions for terrorism. Additionally, participants across all cultures rated risk to self as lower than risk to others (optimistic bias) across all disaster types. These findings suggest that cultural factors may have a greater influence on risk perception than social exposure, and that the belief that one is more immune to disasters compared to others may be a cross-cultural phenomenon. © 2010 Society for Risk Analysis.

  5. Proposal for a questionnaire to assess risk perception concerning a radioactive waste repository

    2011-01-01

    One of the key features for public acceptance of nuclear energy is the belief that radioactive waste can be managed safely, in order to protect human beings from its possible harmful effects in present and future generations. In this sense, it is essential to understand how people perceive the risk associated with radioactive waste and which the main factors driving their attitudes toward its disposal are. One of the ways to achieve this understanding is through opinion polls. In this study, a questionnaire focused on the nuclear energy acceptability issue and its association with radioactive waste management was proposed, covering the following aspects: attitudes towards radioactive waste and nuclear power, credibility on institutions and sectors responsible by the nuclear safety, identification of perceived benefits, risk perception of specific technologies and activities, perception of real risk, emotional reaction comprehension and precautionary principle. Results obtained from a pilot questionnaire application are presented and discussed in this paper. (author)

    Characteristic off-flavours may occur in uncastrated male pigs depending on the accumulation of androstenone and skatole. Feasible processing of strongly tainted carcasses is challenging but gains in importance due to the European ban on piglet castration in 2018. This paper investigates consumers' acceptability of two sausage types: (a) emulsion-type (BOILED) and (b) smoked raw-fermented (FERM). Liking (9 point scales) and flavour perception (check-all-that-apply with both, typical and negatively connoted sensory terms) were evaluated by 120 consumers (within-subject design). Proportion of tainted boar meat (0, 50, 100%) affected overall liking of BOILED, F (2, 238)=23.22, P<.001, but not of FERM sausages, F (2, 238)=0.89, P=.414. Consumers described the flavour of BOILED-100 as strong and sweaty. In conclusion, FERM products seem promising for processing of tainted carcasses whereas formulations must be optimized for BOILED in order to eliminate perceptible off-flavours. Boar taint rejection thresholds may be higher for processed than those suggested for unprocessed meat cuts. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Risk perception is often believed to be an important factor in policy decision making, when it comes to the management of hazardous technology. Research on risk perception by the public since the 1970's has purportedly shown that such perception is emotional and based on ignorance. Experts, on the other hand, have been claimed to be objective and correct in their risk assessments. The present paper reviews a large body of research which has led to a quite different conclusions, viz. that emotions play only a marginal role in risk perception, which is mainly driven by ideological concerns and attitudes. The methodological shortcomings of the prevailing view of risk perception as emotional and simply misinformed are described. (author)

    Cardiovascular diseases are responsible for the largest burden of global mortality. The study of the degree of knowledge of their population risk factors and cardiovascular risk is a priority preventive strategy. A cross-sectional study with 369 people was performed. The sociodemographic variables were cardiovascular risk and perception as well as physical and anthropometric factors. The risk was stratified with the SCORE table. A total of 49.6% were men and 50.4% were women. The proportion of diagnosis was 23.8% in HTA, 39% in hypercholesterolemia, 31.4% in smoking, 26.3% in obesity and 4.6% in diabetes. Concordance between perceived and real cardiovascular risk was very weak. The population has good knowledge about diabetes and acceptable knowledge about hypertension, and hypercholesterolemia but knowledge in prediabetic states and perception of the associated cardiovascular risk is low.

    The Belgian Nuclear Research Center SCK-CEN 2006 risk perception barometer is based on over 1000 Computer Assisted Personal Interviews, taken from persons selected to be representative for the Belgian 18+ population, and all realized in the period March 21st to April 12th 2006. Besides the classical background variables used to obtain the quota for representativity (age, language, habitat, gender and social class), we also included a series of questions assessing the sociological context and the psychological personality profile. The main topics in the survey were I) risk perception and confidence in authorities; II) acceptance of legal norms for food products; III) acceptance of countermeasures for the food chain in case of a radiological contamination and associated consumers behaviour; IV) energy; v) disposal of radioactive waste; vi) perception of the Chernobyl accident and its consequences. Some of the questions asked in 2006 are similar to those enquired in the SCK barometer of 2002, in order to study the time evolution of the risk perception associated with various issues. For the part related to acceptance of legal norms and of countermeasures for the food chain, simulated news bulletins were used in order to better reproduce the real-life context of a contamination.

    This study addressed the lack of research simultaneously examining multiple dimensions of religiousness when predicting rape myth acceptance, and extended prior findings of a mediating role for right-wing authoritarianism (i.e., uncritical submission to authority and aggressive attitude toward those who do not conform to social norms) in the association between religiousness and prejudice. The sample consisted of 99 undergraduate and graduate students ( M age = 31.87 years, 66.7% female, 80.82% White, and 93% Christian affiliated) from a religiously affiliated university in the Midwest United States. As hypothesized, dimensions of religiousness exhibited differential associations with rape myth acceptance. Religious motivation characterized by openness and exploration (i.e., quest religiousness) was a significant negative predictor of rape myth acceptance, directly, and indirectly through right-wing authoritarianism. In contrast, rigid adherence to religious beliefs, assumed to be "right" and absolutely true (i.e., religious fundamentalism), and extrinsically motivated religiousness each exhibited a positive association with rape myth acceptance through right-wing authoritarianism. In addition, internally motivated religiousness and religious fundamentalism each moderated the nonlinear effect for quest predicting rape myth acceptance. Findings suggest that uncritical religious and secular submission to external authorities or uncommitted and nonexploring religiousness may have increased the extent to which persons adhered to rape myths, whereas religious exploration was protective. Practical implications center on the need for socioculturally relevant prevention and intervention efforts with religious identifying college students.

  13. Perception of risk and the future of nuclear power

    Scientists and policy makers were slow to recognize the importance of public attitudes and perceptions in shaping the fate of nuclear power. In 1976, Alvin Weinberg observed: 'As I compare the issues we perceived during the infancy of nuclear energy with those that have emerged during its maturity, the public perception and acceptance of nuclear energy appears to be the question that we missed rather badly.... This issue has emerged as the most critical question concerning the future of nuclear energy.' Today, fourteen years later, the problem of public acceptance is even more critical. Either the problem is damn tough or we have not been working hard enough to solve it (I suspect that both of these assertions are true). Public support for nuclear power has declined steadily for a decade and a half, driven by a number of powerful forces and events. In mid-March of 1979, the movie The China Syndrome had its premier, dramatizing the worst-case predictions of the earliest risk assessment studies. Two weeks later, events at Three Mile Island made the movie appear prophetic. Succeeding years have brought us Chernobyl and other major technological disasters, most notably Bhopal and the Challenger accident. The public has drawn a common message from these accidents - that nuclear (and other) complex technology is unsafe, that expertise is inadequate, and that government and industry cannot be trusted to manage nuclear power safely. These dramatic accidents and the distrust they have spawned have been reinforced by numerous chronic problems involving radiation, such as the discovery of significant radon concentrations in many homes, the continuing battles over the siting of facilities to store or dispose of nuclear wastes, and the disclosures of serious environmental contamination emanating from nuclear weapons facilities (at Hanford, Fernald, Rocky Flats and Savannah River)

    Free-ranging domestic cats (Felis catus) incur and impose risks on ecosystems and represent a complex issue of critical importance to biodiversity conservation and cat and human health globally. Prior social science research on this topic is limited and has emphasized feral cats even though owned cats often comprise a large proportion of the outdoor cat population, particularly in urban areas. To address this gap, we examined public risk perceptions and attitudes toward outdoor pet cats across varying levels of urbanization, including along the wildland-urban interface, in Colorado (U.S.A.), through a mail survey of 1397 residents. Residents did not view all types of risks uniformly. They viewed risks of cat predation on wildlife and carnivore predation on cats as more likely than disease-related risks. Additionally, risk perceptions were related to attitudes, prior experiences with cats and cat-wildlife interactions, and cat-owner behavior. Our findings suggest that changes in risk perceptions may result in behavior change. Therefore, knowledge of cat-related risk perceptions and attitudes could be used to develop communication programs aimed at promoting risk-aversive behaviors among cat owners and cat-management strategies that are acceptable to the public and that directly advance the conservation of native species. © 2016 Society for Conservation Biology.

    Risk perceptions are only slightly correlated with the expected values of a probability distribution for negative health impacts. Psychometric studies have documented that context variables such as dread or personal control are important predictors for the perceived seriousness of risk. Studies about cultural patterns of risk perceptions emphasize different response set to risk information, depending on cultural priorities such as social justice versus personal freedom. This chapter reports the major psychological research pertaining to the factors that govern individual risk perception and discusses the psychometric effects due to people's risk perception and the experience of severe stress. The relative importance of the psychometric content variables, the signals pertaining to each health risks and symbolic beliefs are explained. (Author)

    In environmental surveys, risk perception may be a source of bias when information on health outcomes is reported using questionnaires. Using the data from a survey carried out in the largest chipboard industrial district in Italy (Viadana, Mantova), we devised a score of health risk perception and described its determinants in an adult population. In 2006, 3697 parents of children were administered a questionnaire that included ratings on 7 environmental issues. Items dimensionality was studied by factor analysis. After testing equidistance across response options by homogeneity analysis, a risk perception score was devised by summing up item ratings. Factor analysis identified one latent factor, which we interpreted as health risk perception, that explained 65.4% of the variance of five items retained after scaling. The scale (range 0-10, mean ± SD 9.3 ± 1.9) had a good internal consistency (Cronbach's alpha 0.87). Most subjects (80.6%) expressed maximum risk perception (score = 10). Italian mothers showed significantly higher risk perception than foreign fathers. Risk perception was higher for parents of young children, and for older parents with a higher education, than for their counterparts. Actual distance to major roads was not associated with the score, while self-reported intense traffic and frequent air refreshing at home predicted higher risk perception. When investigating health effects of environmental hazards using questionnaires, care should be taken to reduce the possibility of awareness bias at the stage of study planning and data analysis. Including appropriate items in study questionnaires can be useful to derive a measure of health risk perception, which can help to identify confounding of association estimates by risk perception.

  19. Rethinking the relationship between flood risk perception and flood management.

    Although flood risk perceptions and their concomitant motivations for behaviour have long been recognised as significant features of community resilience in the face of flooding events, there has, for some time now, been a poorly appreciated fissure in the accompanying literature. Specifically, rationalist and constructivist paradigms in the broader domain of risk perception provide different (though not always conflicting) contexts for interpreting evidence and developing theory. This contribution reviews the major constructs that have been applied to understanding flood risk perceptions and contextualises these within broader conceptual developments around risk perception theory and contemporary thinking around flood risk management. We argue that there is a need to re-examine and re-invigorate flood risk perception research, in a manner that is comprehensively underpinned by more constructivist thinking around flood risk management as well as by developments in broader risk perception research. We draw attention to an historical over-emphasis on the cognitive perceptions of those at risk to the detriment of a richer understanding of a wider range of flood risk perceptions such as those of policy-makers or of tax-payers who live outside flood affected areas as well as the linkages between these perspectives and protective measures such as state-supported flood insurance schemes. Conclusions challenge existing understandings of the relationship between risk perception and flood management, particularly where the latter relates to communication strategies and the extent to which those at risk from flooding feel responsible for taking protective actions.

  20. Radiation risk perception and public information

    We as Health Physicists face what, at many times, appears to be a hopeless task. The task simply stated is informing the public about the risks (or lack thereof) of radiation. Unfortunately, the public has perceived radiation risks to be much greater than they actually are. An example of this problem is shown in a paper by Arthur C. Upton. Three groups of people -- the League of Women Voters, students, and Business and Professional Club members -- were asked to rank 30 sources of risk according to their contribution to the number of deaths in the United States. Not surprisingly, they ranked nuclear power much higher and medical x-rays much lower than the actual values. In addition to the perception problem, we are faced with another hurdle: health physicists as communicators. Members of the Health Physics Society (HPS) found that the communication styles of most health physicists appear to be dissimilar to those of the general public. These authors administered the Myers-Briggs Type Indicator to the HPS Baltimore-Washington Chapter. This test, a standardized test for psychological type developed by Isabel Myers, ask questions that provide a quantitative measure of our natural preferences in four areas. Assume that you as a health physicist have the necessary skills to communicate information about radiation to the public. Health physicists do nothing with these tools. Most people involved in radiation protection do not get involved with public information activies. What I will attempt to do is heighten your interest in such activities. I will share information about public information activities in which I have been involved and give you suggestions for sources of information and materials. 2 refs., 1 tab

    The aim of this study was to elucidate whether physicians' illness perceptions correlate with their frustration or resistance to accepting patients with fibromyalgia (FM). In this cross-sectional postal survey, questionnaires were sent to member physicians of the Japan College of Rheumatology and Japan Rheumatism Foundation. Measures collected included the Brief Illness Perception Questionnaire with Causal Attribution, the Illness Invalidation Inventory, and the Difficult Doctor-Patient Relationship Questionnaire (DDPRQ-10). Multiple logistic regression was performed to examine associations between the DDPRQ-10 and resistance to accepting patients with FM for treatment. We analyzed data from 233 physicians who had experience in consulting with patients with FM. Only 44.2 % answered that they wanted to accept additional patients with FM. Physicians' frustration was associated with difficulty controlling symptoms, patients' emotional responses, and causal attribution of FM to patient internal factors. Conversely, lower levels of frustration were associated with causal attributions to biological factors and uncontrollable external factors. However, the "difficult patient" perception did not correlate with resistance to accepting patients with FM. Difficulty controlling symptoms with treatment was the one factor common to both physicians' frustration and resistance to accepting patients with FM. Physicians may hesitate to accept patients with FM not because of the stigmatic image of the "difficult patient," but instead because of the difficulty in controlling the symptoms of FM. Thus, to improve the quality of consultation, physicians must continuously receive new information about the treatments and causes of FM.

    1999-01-01

    What have we learned about risk perception? Let me summarize a few highlights: Perceived risk is at the present highest with regard to acute economic needs, but the environment and nuclear technology are also important. Nuclear technology has a special role in being perceived as very low in 'control', i.e. if you can protect yourself from its hazards. Media do play an important role in risk perception, but it is more subtle than most often believed. Media do affect our beliefs by the information they bring us, but not necessarily by increasing the 'availability of what we already know'. Trust is not the primary factor in risk perception that it often is believed to be - it does play a role at a moderate level of power. It may be that trust is a necessary but not sufficient factor for risk 'acceptance'. In Western Europe, we have noted very large variations among countries both with regard to trust and perceived risk. Inclusion of other societies would probably have meant observation of even greater variation. The RISKPERCOM project serves as a starting point for further work on risk perception and technology. Attitudes and values need to be studied in a broader frame than merely perceived risk, as the project has shown. Future research on such acute topics as nuclear waste is called for; the project has already produced a number of results in that area but space restrictions preclude me from reviewing them here

    In this work we characterize the public perception of one kind of ecological risk—blue-algae bloom in Hongze Lake, China, based on the psychometric paradigm method. In the first survey of May 2008, 300 respondents of Sihong County adjacent to Hongze Lake were investigated, with a total of 156 questionnaires returned. Then in a second survey of July 2008, 500 respondents from the same research area were investigated, with 318 questionnaires collected. This research firstly attempted to explore the local respondents’ degree of concern regarding ecological changes to Hongze Lake in the last ten years. Secondly, to explore the public perception of blue-algae bloom compared to three typical kinds of hazards including earthquake, nuclear power and public traffic. T-test was used to examine the difference of risk perception in these four hazards over time. The third part of this research, with demographic analysis and nonparametric statistical test, predicted the different groups of respondents’ willingness to accept (WTA) risk of blue-algae bloom in two surveys. Using multiple linear regression analysis, the risk perception model explained 28.3% of variance in the WTA blue-algae bloom risk. The variables of Knowledge, Social effect, Benefit, Controllability and Trust in government were significantly correlated with WTA, which implied that these variables were the main influencing factors explaining the respondents’ willingness to accept risk. The results would help the Chinese government to comprehend the public’s risk perception of the lake ecosystem, inducing well designed communication of risks with public and making effective mitigation policies to improve people’s rational risk judgment.

    A questionnaire survey was conducted on radiation risk and medical exposure, particularly in applications involving children. The survey was targeted at nurses (170 females) engaged in important roles in communicating risk regarding medical exposure. The questionnaire survey yielded the following findings. A significant number of respondents associated the word radiation' with 'cancer treatment,' 'exposure,' and 'X-ray pictures.' Perceptions about 'food exposure' differed between respondents with children and those without. Among the potential health problems posed by radiation, effects on children,' 'cancer and leukemia,' and 'genetic effects' were perceived as the most worrisome. Significant differences in perception were noted regarding infertility between respondents with children and those without. Concerning the effects of medical exposure on fetuses/children, only 10 percent of all respondents replied that they were not anxious about negative effects in either case. Among the respondents who felt uneasy about these aspects, most tended to assess exposed parts, doses, damage potentially suffered, timing of occurrence, and uncertainty, based on their professional experience and knowledge, to rationally distinguish acceptable risks from unacceptable ones and to limit concern to the unacceptable aspects.

    The extent to which people are willing to take on risk, i.e. their risk preferences as well as subjective risk perception plays a major role in explaining their behavior. This is of particular relevance in agricultural production, which is inherently risky. The data presented here was collected amongst a total of 64 German farmers in 2015. It includes results of three different risk preference elicitation methods (multiple price list, business statements in four relevant domains and general self-assessment) as well as risk perception. Additionally, farm business characteristics (e.g. size, farm-level workforce, succession) and personal farmer characteristics (e.g. age, gender, risk literacy) are included.

    Many people claim that nuclear power technology should be subjected to stricter safety criteria than other mega-technologies, and some insist that every risk should be eliminated from the technology. For the future of nuclear technology it is one of the most important tasks to provide insight for the people seeking zero-risk safety from nuclear technology by understanding the mechanism of risk perception, especially the mechanism resulting in the zero-risk imperative. Specifically we describe the distribution of the people claiming zero-risk technology, risk perceptions and their factors, as well as the relationship between the risk perceptions and attitude structures. Our societies enjoy the benefits of mega-technologies, however at the same time we have some costs to put them to practical use, especially the costs on environments and on human health. And so, on decision-making processes of whether and how much we will practically use mega-technologies, public acceptance or consensus in societies are absolutely indispensable. Through the decision-making processes in societies, some people sometimes do not accept the 'risk evaluation' that scientists and technologists made. Some people believe that our lives should and could be perfectly safe (zero-risk perception), and they think or insist that we should not use the mega-technologies if we are not able to achieve perfect safety. In Japan, many people seem to have typical zero-risk perception toward nuclear power technology. While other people think that anywhere in our world we have no perfect safety, and that 'risk' should be evaluated by the ratio between costs and benefits (comparative-risk perception). On the other hand, in our democratic societies, we have political rules that the electorates, common people, ultimately decide whether mega-technologies are used or not, and how much costs are to be spent to reduce hazards. So, it is important to clarify the nature of the common people's risk perceptions and

  8. Vulnerability and social justice as factors in emergent U.S. nanotechnology risk perceptions.

    2011-11-01

    As an emerging domain of risk research, nanotechnologies engender novel research questions, including how new technologies are encountered given different framing and contextual detail. Using data from a recent U.S. national survey of perceived risks (N= 1,100), risk versus benefit framings and the specific social positions from which people encounter or perceive new technologies are explored. Results indicate that vulnerability and attitudes toward environmental justice significantly influenced risk perceptions of nanotechnology as a broad class, while controlling for demographic and affective factors. Comparative analyses of different examples of nanotechnology applications demonstrated heightened ambivalence across acceptability when risk versus benefit information was provided with application descriptions (described in short vignettes as compared to the general category "nanotechnology," absent of risk or benefit information). The acceptability of these nano-specific vignettes varied significantly in only some cases given indexes of vulnerability and attitudes toward environmental justice. However, experimental narrative analyses, using longer, more comprehensive descriptive passages, show how assessments of risks and benefits are tied to the systematically manipulated psychometric qualities of the application (its invasiveness and controllability), risk messaging from scientists, and the social implications of the technology with regard to justice. The article concludes with discussion of these findings for risk perception research and public policy related to nanotechnology and possibly other emerging technologies. © 2011 Society for Risk Analysis.

    This report investigates how communities hosting nuclear facilities form and express perceptions of risk and how these risk perceptions affect local economic development. Information was collected from site visits and interviews with plant personnel, officials of local and state agencies, and community activists in the hosting communities. Six commercial nuclear fuel production facilities and five nuclear facilities operated for the US Department of Energy by private contractors were chosen for analysis. The results presented in the report indicate that the nature of risk perceptions depends on a number of factors. These factors are (1) level of communication by plant officials within the local community, (2) track record of the facility. operator, (3) process through which community and state officials receive information and form opinions, (4) level of economic links each plant has with the local community, and (15) physical characteristics of the facility itself. This report finds that in the communities studied, adverse ask perceptions have not affected business location decisions, employment levels in the local community, tourism, or agricultural development. On the basis of case-study findings, this report recommends that nuclear facility siting programs take the following observations into account when addressing perceptions of risk. First, the quality of a facility`s participation with community activists, interest groups, and state agencies helps to determine the level of perceived risk within a community. Second, the development of strong economic links between nuclear facilities and their host communities will produce a higher level of acceptance of the nuclear facilities.

This report finds that in the communities studied, adverse ask perceptions have not affected business location decisions, employment levels in the local community, tourism, or agricultural development. On the basis of case-study findings, this report recommends that nuclear facility siting programs take the following observations into account when addressing perceptions of risk. First, the quality of a facility's participation with community activists, interest groups, and state agencies helps to determine the level of perceived risk within a community. Second, the development of strong economic links between nuclear facilities and their host communities will produce a higher level of acceptance of the nuclear facilities

    Negative consequences of alcohol abuse during adolescence have been extensively described. Consequently, different interventions have been developed to address this issue. This article describes the implementation and evaluation of Iudicium, an educational drama-based intervention designed to increase risk perception of alcohol abuse. In this activity, high school students judge a case in which alcohol consumption had negative consequences (e.g., fights, unwanted pregnancy, and car accident). A trial is simulated and after that, a debriefing takes place during which the activity is discussed and informational materials on the effects of alcohol is provided and commented. A total of 318 students (55.7% females and 44.3% males) from five high schools participated in the study. Data regarding risk perception of alcohol abuse and adequacy of the activity was collected before and after the intervention. Results suggest that Iudicium was effective in increasing risk perception of abusive drinking, reaching a 34% of increase regarding risk perception. Participants highlighted the experiential component of Iudicium as a strength. The intervention was well-accepted, easy to understand and apparently an effective tool for increasing risk perception of alcohol abuse amongst high school students.

    Experts are perceived to be veridical and to focus only on objective data when evaluating risk. Only a few research studies have attempted to characterize the subjectivity in risk evaluation among experts. The hypothesis of this study is that expert evaluation of a pharmaceutical drug can be partly explained by dimensions that describe the drug and by individual characteristics. Seventy-five medical assessors in 9 EU countries evaluated a list of 28 pharmaceutical drugs using 4 scales: risk, benefit, seriousness of harm, and patients' knowledge of the risk. They were also given a mock "clinical dossier" and asked to rate it on 8 dimensions: risk, benefit, worry, magnitude of the exposure, scientific knowledge of the risk, familiarity of the risk, ethical concerns, and risk acceptability. Female assessors perceived significantly higher benefits than men for a large number of the 28 drugs. Principal component analysis of the ratings for the clinical dossiers revealed 2 underlying components: seriousness of harm and scientific evidence. A regression model predicting the risk perception of the drug showed that the variables seriousness of harm (benefit, worry, magnitude of exposure, ethical concerns, and risk acceptability), years of regulatory experience, gender, and type of drug explained 54% of the variability among assessors. Assessors' view of the risks associated with pharmaceutical drugs is influenced by worry for patient safety, magnitude of patient exposure, and ethical concerns. These dimensions may influence their perceptions of benefit and risk acceptability. Senior assessors are more risk averse than junior assessors, and female assessors seem to be sensitive to the promise of benefit from medicines and consequently may be less risk averse than male assessors.

    This article examines why, as suggested by the Three Mile Island Nuclear Station (TMI) event, the public is more inclined to evacuate in response to a radiation release than to a natural hazard. During the TMI incident, for example, did authorities present confusing or conflicting information or did the public have an exaggerated perception of radiation risk. Behavioral intention studies are combined with risk perception analyses to ascertain (1) the extent to which intentions to evacuate can be generalized from one sample to another and from one hazard to another, (2) the degree to which behavioral intentions are related to specific dimensions of risk perception, and (3) how public perceptions of risk compare with estimates of risk produced by reactor accident consequence analyses

  20. An evaluation of the exemption level for the radiation protection regulation based on the social risk acceptance in Korea

    1998-02-01

    Radiation protection is based not only on the science but also on the political, social, economical and emotional factors, so a policy decision for a factor like the exemption level in this field must be considered social expectation and valuation as well as scientific evaluation. In this paper, an attempt was made to get a rationale on the exemption level, which has a significant meaning in radiation protection, by means of surveying the social risk acceptance in Korea. Risk perception data were collected by mail surveys to the respondents randomly selected in the city of Seoul. A poor response rate, 156 out of 400, was observed. The result showed that the majority of the respondents agreed upon setting a de mini mis level of risk and the favoured de mini mis level appeared to be in the range of 10 -6 yr -1 to 10 -7 yr -1 , which is consistent with the level suggested by other organizations: ICRP, EPA and NRPB. Approximately the same risk level, unfortunately, was obtained for the risk limits against a harmful agent, which makes no sense. It can be attributed to mis-communication due to the questionnaires inadequately designed. The acceptable risk level for a single practice was selected to be 1/100 or less of the risk limits, which seemed overly conservative, but could be understood in the light of the public attitude of outrage. There seems to be tendency that the public recognize the risk significant if it is not de mini mis. This study should not be regarded as one giving a satisfactory conclusion but a preliminary attempt to evaluate the acceptable risk level. More endeavors in design of questionnaires are needed to communicate successfully with the members of the public

  1. Acceptably aware during general anaesthesia: 'dysanaesthesia'--the uncoupling of perception from sensory inputs.

    Science.gov (United States)

    Pandit, Jaideep J

    2014-07-01

    This review makes the case for 'dysanaesthesia', a term encompassing states of mind that can arise in the course of anaesthesia during surgery, characterised by an uncoupling of sensation and perceptual experience. This is reflected in a macroscopic, functional model of anaesthetically-relevant consciousness. Patients in this state can be aware of events but in a neutral way, not in pain, sometimes personally dissociated from the experiences. This makes events associated with surgery peripheral to their whole experience, such that recall is less likely and if it exists, makes any spontaneous report of awareness unlikely. This state of perception-sensation uncoupling is therefore broadly acceptable (a minimum requirement for acceptable anaesthesia) but since it is likely a dose-related phenomenon, may also represent a precursor for awareness with adverse recall. This hypothesis uniquely explains the often inconsistent responses seen during the experimental paradigm of the 'isolated forearm technique', wherein apparently anaesthetised patients exhibit a positive motor response to verbal command, but no spontaneous movement to surgery. The hypothesis can also explain the relatively high incidence of positive response to relatively direct questions for recall (e.g., using the Brice questionnaire; ∼1:500; the vast majority of these being neutral reports) versus the very low incidence of spontaneous reports of awareness (∼1:15,000; a higher proportion of these being adverse recollections). The hypothesis is consistent with relevant notions from philosophical discussions of consciousness, and neuroscientific evidence. Dysanaesthesia has important implications for research and also for the development of appropriate monitoring. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available Abstract Background Risk perception is considered a motivating factor for adopting preventive behaviors. This study aimed to verify the demographic characteristics and cancer family history that are predictors of risk perception and to verify if risk perception is a predictor of colonoscopy adherence. Methods Individuals with a family colorectal cancer history as indicated by a proband with cancer were interviewed by telephone. They responded to a questionnaire covering demographic characteristics, colonoscopy history and four questions on risk perception. Tests of multiple linear regression and logistic regression were used to identify associations between dependent and independent variables. Results The 117 participants belonged to 62 families and had a mean age of 45.2 years. The majority of these individuals were female (74.4% and from families who met the Amsterdam Criteria (54.7%. The average risk perception was 47.6%, with a median of 50%. The average population perception of individual risk was 55.4%, with a median of 50%. Variables associated with a higher risk perception were age, gender, religion, school level, income, and death of a family member. The variable predicting colonoscopy was receiving medical information regarding risk (odds ratio OR 8.40. Conclusions We found that family cancer history characteristics (number of relatives with cancer, risk classification are associated with adequate risk perception. Risk perception does not predict colonoscopy in this sample. The only variable that predicted colonoscopy was receiving medical information recommending screening.

  3. How Fear-Arousing News Messages Affect Risk Perceptions and Intention to Talk About Risk.

    2016-09-01

    Building on the theoretical arguments of the impersonal-impact and differential-impact hypotheses, this study has a twofold purpose: first, to demonstrate how fear-arousing media messages about risk are associated with personal-level risk perception, as well as, and perhaps more so than, societal-level risk perception; and second, to examine how the resulting risk perceptions can mediate intention to talk about the risk with family and friends. A news message evaluation study was conducted among the general public in South Korea concerning two major risks, carcinogens and bovine spongiform encephalopathy (BSE). Two sets of structural equation models reveal three main findings: (a) Fear-arousing news messages are positively related to personal-level risk perception, as well as to societal-level risk perception; (b) fear-arousing news messages result in intention to talk about the risk directly and indirectly through risk perception; and (c) personal-level risk perception appears more strongly related to intention to talk than does societal-level risk perception, although such relationships may vary across risk topics.

    Abrupt environmental pollution accidents cause considerable damage worldwide to the ecological environment, human health, and property. The concept of acceptable risk aims to answer whether or not a given environmental pollution risk exceeds a societally determined criterion. This paper presents a case study on acceptable environmental pollution risk conducted through a questionnaire survey carried out between August and October 2014 in five representative districts and two counties of Zhangjiakou City, Hebei Province, China. Here, environmental risk primarily arises from accidental water pollution, accidental air pollution, and tailings dam failure. Based on 870 valid questionnaires, demographic and regional differences in public attitudes towards abrupt environmental pollution risks were analyzed, and risk acceptance impact factors determined. The results showed females, people between 21-40 years of age, people with higher levels of education, public servants, and people with higher income had lower risk tolerance. People with lower perceived risk, low-level risk knowledge, high-level familiarity and satisfaction with environmental management, and without experience of environmental accidents had higher risk tolerance. Multiple logistic regression analysis indicated that public satisfaction with environmental management was the most significant factor in risk acceptance, followed by perceived risk of abrupt air pollution, occupation, perceived risk of tailings dam failure, and sex. These findings should be helpful to local decision-makers concerned with environmental risk management (e.g., selecting target groups for effective risk communication) in the context of abrupt environmental accidents.

    Risks are assessed very differently in our modern society. While a number of everyday risks, some of which are hardly perceptible while others are quite spectacular, are accepted to a considerable extent, many other risks, often minor ones, are overemphasized and rejected. Risk assessment in the minds of people is a function of a number of subjective, emotional factors with decisive psychological components which lead to irrational assessment especially of a number of manmade risks, including nuclear power. Factors to be mentioned in the assessment of the risks of nuclear power, among others, are the imaginary phenomenon of radioactivity and nuclear fission; the growing intrusion of technology into our living environment; the need to fall back upon expert knowledge; and the intuitive, wrong correlation of technical expense for safety with the perceived risk. As is seen, opinions are formed not solely on the basis of rational findings, but are influenced by many factors, some of which cannot be reproduced in a rational way. This makes it imperative to include in the debate about risks of technology, specifically the discussion about the use of nuclear power, the psychological aspect in order to arrive at a reasonable way for society to handle technology. (orig.) [German] Risiken in unserer modernen Gesellschaft werden sehr unterschiedlich bewertet. Waehrend eine Reihe alltaeglicher, wenig auffaelliger Risiken, aber auch spektakulaere Risiken in erheblichem Masse akzeptiert werden, werden andere, vielfach sehr kleine Risiken mit einer Ueberbewertung abgelehnt.

Fuer die Beurteilung der Risiken der Kernenergie sind unter anderem als Faktoren zu nennen: das imaginaere Phaenomen von

    Economists have argued persuasively that our goals are wider than just risk minimization, and that they include a prudent weighing of costs and benefits. This economic line of thought recognizes that our policy goals are complex. As we widen the range of goals we are willing to entertain, though, we need to check that the methods we customarily employ are appropriate for the tasks to which we customarily apply them. This paper examines some economic methods of risk assessment, in light of the question of what our policy goals are and should be. Once the question of goals is open, more complexities than just cost intrude: what the public wants and why begs to be addressed. This leads us to the controversial issue of public risk perceptions. We have now examined a number of procedures that experts use to make public policy decisions. Behind all these issues is always the question of social welfare: what actions can we take, what policies should we embrace, to make the world a better place? In many cases, the public and the experts disagree about what the right choice is. In the first section, we saw a possible defense of the experts based on democratic theory: the people's participation, and even their will, can be legitimately set aside in the pursuit of their true interests. If this defense is to work, a great deal of weight rests on the question of the people's interests and the competence and integrity of the experts' pursuit of it. But at the same time, social preferences are ill-defined, and so are not good candidates for rational actor theory. Both the prescriptive legitimacy claim and the very workings of formal theory we have seen to depend on informal, qualitative, political judgments. Unfortunately, we have also seen a steady pattern of expert reliance on technical procedures even when they were manifestly unsuited to the task. The experts seem so intent on excluding informal thought that they would prefer even a bad quantitative process to a qualitative

  12. A discussion of the limitations of the psychometric and cultural theory approaches to risk perception

    International Nuclear Information System (INIS)

    Sjoeberg, L.

    1996-01-01

    Risk perception has traditionally been conceived as a cognitive phenomenon, basically a question of information processing. The very term perception suggests that information processing is involved and of crucial importance. Kahneman and Tversky suggested that the use of 'heuristics' in the intuitive estimation of probabilities accounts for biased probability perception, hence claiming to explain risk perception as well. The psychometric approach of Slovic et al, a further step in in the cognitive tradition, conceives of perceived risk as a function of general properties of a hazard. However, the psychometric approach is shown here to explain only about 20% of the variance of perceived risk, even less of risk acceptability. Its claim to explanatory power is based on a statistical illusion: mean values were investigated and accounted for, across hazards. A currently popular alternative to the psychometric tradition, Cultural Theory, is even less successful and explains only about 5% of the variance of perceived risk. The claims of this approach were also based on a statistical illusion: 'significant' results were reported and interpreted as being of substantial importance. The present paper presents a new approach: attitude to the risk generating technology, general sensitivity to risks and specific risk explained well over 60% of the variance of perceived risk of nuclear waste, in a study of extensive data from a representative sample of the Swedish population. The attitude component functioning as an explanatory factor of perceived risk, rather than as a consequence of perceived risk, suggests strongly that perceived risk is something other than cognition. Implications for risk communication are discussed. (author)

  13. On the use of risk acceptance criteria in the offshore oil and gas industry

    2005-01-01

    Risk acceptance criteria, as upper limits of acceptable risks, have been used for offshore activities on the Norwegian Continental Shelf for more than 20 years. The common thinking has been that risk analyses and assessments cannot be conducted in a meaningful way without the use of such criteria. The ALARP principle also applies, but the risk acceptance criteria have played a more active role in the assessment processes than seen for example in the UK. Recently there has, however, been a discussion about the suitability of risk acceptance criteria to assess and control risks. The purpose of this paper is to contribute to this discussion by presenting and discussing a risk analysis regime that is not based on the use of risk acceptance criteria at all. We believe that we can do better if cost-effectiveness (in a wide sense) is the ruling thinking rather than adoption of pre-defined risk acceptance limits. This means a closer resemblance with the ALARP principle as adopted in the UK and other countries, but is not a direct application of this practice. Also the building blocks of the common way of applying the ALARP principle are reviewed. The Norwegian offshore oil and gas industry is the starting point, but the discussion is to large extent general

    One factor women consider when deciding whether to pursue amniocentesis is the risk of miscarriage. People use mechanisms like anchoring, or the prior belief regarding the magnitude of risk, as a frame of reference for new information. This study aimed to determine a woman's perception of miscarriage risk associated with amniocentesis before and after genetic counseling and to determine what factors anchor a woman's perception of miscarriage risk. One hundred thirteen women being seen for prenatal genetic counseling and possible amniocentesis at six Houston clinics participated in the two-part anonymous survey. While most women (56.7 %) perceived the risk as low or average pre-counseling and indicated the numeric risk of amniocentesis as risk as risk perception did not change after the genetic counseling session (60 %). Those who changed their feeling about the risk after counseling showed a decreased perception of the risk (p perception of the risk (p = 0.017) whereas those who declined amniocentesis were more likely to view the risk as high (p = 0.004). The only two anchoring factors that had an effect were having a friend or relative with a personal or family history of a genetic disorder (p = 0.001) and having a child already (p = 0.038); both were associated with a lower risk perception. The lack of significant factors may reflect the uniqueness of each patient's risk assessment framework and reinforces the importance of genetic counseling to elucidate individual concerns, particularly as non-invasive prenatal testing becomes more widely available and further complicates the prenatal testing landscape.

    Risk communication and vaccines is complex and the nature of risk perception is changing, with perceptions converging, evolving and having impacts well beyond specific geographic localities and points in time, especially when amplified through the Internet and other modes of global communication. This article examines the globalization of risk perceptions and their impacts, including the example of measles and the globalization of measles, mumps and rubella (MMR) vaccine risk perceptions, and calls for a new, more holistic model of risk assessment, risk communication and risk mitigation, embedded in an ongoing process of risk management for vaccines and immunization programmes. It envisions risk communication as an ongoing process that includes trust-building strategies hand-in-hand with operational and policy strategies needed to mitigate and manage vaccine-related risks, as well as perceptions of risk.

    Many factors influence how people form risk perceptions. Farmers' perceptions of risk and levels of risk aversion impact on decision-making about such things as technology adoption and disease management practices. Irrespective of the underlying factors that affect risk perceptions, those perceptions can be summarized by variables capturing impact and uncertainty components of risk. We discuss a new framework that has the subjective probability of disease and the cost of decision errors as its central features, which might allow a better integration of social science and epidemiology, to the benefit of plant disease management. By focusing on the probability and cost (or impact) dimensions of risk, the framework integrates research from the social sciences, economics, decision theory, and epidemiology. In particular, we review some useful properties of expected regret and skill value, two measures of expected cost that are particularly useful in the evaluation of decision tools. We highlight decision-theoretic constraints on the usefulness of decision tools that may partly explain cases of failure of adoption. We extend this analysis by considering information-theoretic criteria that link model complexity and relative performance and which might explain why users reject forecasters that impose even moderate increases in the complexity of decision making despite improvements in performance or accept very simple decision tools that have relatively poor performance.

  20. Nanotechnology risk perceptions and communication: emerging technologies, emerging challenges.

    Nanotechnology involves the fabrication, manipulation, and control of materials at the atomic level and may also bring novel uncertainties and risks. Potential parallels with other controversial technologies mean there is a need to develop a comprehensive understanding of processes of public perception of nanotechnology uncertainties, risks, and benefits, alongside related communication issues. Study of perceptions, at so early a stage in the development trajectory of a technology, is probably unique in the risk perception and communication field. As such it also brings new methodological and conceptual challenges. These include: dealing with the inherent diversity of the nanotechnology field itself; the unfamiliar and intangible nature of the concept, with few analogies to anchor mental models or risk perceptions; and the ethical and value questions underlying many nanotechnology debates. Utilizing the lens of social amplification of risk, and drawing upon the various contributions to this special issue of Risk Analysis on Nanotechnology Risk Perceptions and Communication, nanotechnology may at present be an attenuated hazard. The generic idea of "upstream public engagement" for emerging technologies such as nanotechnology is also discussed, alongside its importance for future work with emerging technologies in the risk communication field. © 2011 Society for Risk Analysis.

    Lay judgments of environmental risks are central to both immediate decisions (e.g., taking shelter from a storm) and long-term ones (e.g., building in locations subject to storm surges). Using methods from quantitative psychology, we provide a general approach to studying lay perceptions of environmental risks. As a first application of these methods, we investigate a setting where lay decisions have not taken full advantage of advances in natural science understanding: tornado forecasts in the US and Canada. Because official forecasts are imperfect, members of the public must often evaluate the risks on their own, by checking environmental cues (such as cloud formations) before deciding whether to take protective action. We study lay perceptions of cloud formations, demonstrating an approach that could be applied to other environmental judgments. We use signal detection theory to analyse how well people can distinguish tornadic from non-tornadic clouds, and multidimensional scaling to determine how people make these judgments. We find that participants (N = 400 recruited from Amazon Mechanical Turk) have heuristics that generally serve them well, helping participants to separate tornadic from non-tornadic clouds, but which also lead them to misjudge the tornado risk of certain cloud types. The signal detection task revealed confusion regarding shelf clouds, mammatus clouds, and clouds with upper- and mid-level tornadic features, which the multidimensional scaling task suggested was the result of participants focusing on the darkness of the weather scene and the ease of discerning its features. We recommend procedures for training (e.g., for storm spotters) and communications (e.g., tornado warnings) that will reduce systematic misclassifications of tornadicity arising from observers’ reliance on otherwise useful heuristics.

  4. Climate change risk perception and communication: addressing a critical moment?

    2012-06-01

    Climate change is an increasingly salient issue for societies and policy-makers worldwide. It now raises fundamental interdisciplinary issues of risk and uncertainty analysis and communication. The growing scientific consensus over the anthropogenic causes of climate change appears to sit at odds with the increasing use of risk discourses in policy: for example, to aid in climate adaptation decision making. All of this points to a need for a fundamental revision of our conceptualization of what it is to do climate risk communication. This Special Collection comprises seven papers stimulated by a workshop on "Climate Risk Perceptions and Communication" held at Cumberland Lodge Windsor in 2010. Topics addressed include climate uncertainties, images and the media, communication and public engagement, uncertainty transfer in climate communication, the role of emotions, localization of hazard impacts, and longitudinal analyses of climate perceptions. Climate change risk perceptions and communication work is critical for future climate policy and decisions. © 2012 Society for Risk Analysis.

    Following the renewed attention for non-structural flood risk reduction measures implemented at the household level, there has been an increased interest in individual flood risk perceptions. The reason for this is the commonly-made assumption that flood risk perceptions drive the motivation of individuals to undertake flood risk mitigation measures, as well as the public's demand for flood protection, and therefore provide useful insights for flood risk management.

  6. Views of Science Teaching and Learning by Immigrant Somali Elders: Perceptions of Conflict and Acceptance

    Science.gov (United States)

    Albrecht, Nancy Jean

    The gap between a student's home culture and that of classroom science may create challenges for students and families, especially those from recent immigrant cultures, including refugees. As a result, science learning in schools may require a form of cultural border crossing between home cultures and the culture of classroom science. Given this, as educators, how do we make these borders more porous for better science learning experiences? Using the frameworks of funds of knowledge, culturally relevant pedagogy, and socio-constructivism, this study focuses on the perspectives of Somali-American elders and parents about school science. Designed as an in-depth interview study, five purposefully selected participants were interviewed over a period of two years. The guiding questions for the study included: 1) What are the perceptions of Somali elders about school science? and 2) How do Somali elders believe science teaching and learning can facilitate Somali students' engagement in science?. Analysis of the interview data revealed that Somali-American adults have complicated perceptions of school science that include both conflicts and acceptance with current pedagogy and content. For example, science education was highly valued by both individuals and the Somali community, both as a way for individuals to attain economic prosperity and respect, but also as a way to lift up the Somali diaspora, both here and in their native homeland. On the other hand, science was also viewed as an abstract discipline with little connection to students' and families' everyday home lives. Moreover, due to the intrinsic role that Islam plays in traditional and contemporary Somali culture, several areas of science education, including geology, evolution and sex education, were viewed as problematic and unresolvable. Various potential areas of funds of knowledge and culturally relevant pedagogy were discussed including nutrition, food preparation and storage, health education, and

    Previous studies suggest that efficacy is more important than side-effect risks to psoriasis patients. However, those studies did not consider potentially fatal risks of biologic treatments. To quantify the risks patients are willing to accept for improvements in psoriasis symptoms. Adults with a self-reported physician diagnosis of psoriasis were recruited through the National Psoriasis Foundation. Using a discrete-choice experiment, patients completed a series of nine choice questions, each including a pair of hypothetical treatments. Treatments were defined by severity of plaques, body surface area (BSA), and 10-year risks of tuberculosis, serious infection and lymphoma. For complete clearance of 25% BSA with mild plaques, respondents (n = 1608) were willing to accept a 20% (95% confidence interval: 9-26%) risk of serious infection, 10% (5-15%) risk of tuberculosis and 2% (1-3%) risk of lymphoma. For complete clearance of 25% BSA with severe plaques, respondents were willing to accept a 54% (48-62%) risk of serious infection, 36% (28-49%) risk of tuberculosis and 8% (7-9%) risk of lymphoma. Respondents were asked to evaluate hypothetical scenarios. Actual treatment choices may differ. Respondents were willing to accept risks above likely clinical exposures for improvements in psoriasis symptoms. Individual risk tolerances may vary.

    A need exists for public health strategies regarding extreme weather disasters, which in recent years have become more frequent. This study aimed to understand the public's perception of extreme cold and its related health risks, which may provide detailed information for public health preparedness during an extreme cold weather event. To evaluate public perceptions of cold-related health risk and to identify vulnerable groups, we collected responses from 891 participants in a face-to-face survey in Harbin, China. Public perception was measured by calculating the score for each perception question. Locals perceived that extreme cold weather and related health risks were serious, but thought they could not avoid these risks. The significant difference in perceived acceptance level between age groups suggested that the elderly are a "high health risk, low risk perception" group, meaning that they are relatively more vulnerable owing to their high susceptibility and low awareness of the health risks associated with extreme cold weather. The elderly should be a priority in risk communication and health protective interventions. This study demonstrated that introducing risk perception into the public health field can identify vulnerable groups with greater needs, which may improve the decision-making of public health intervention strategies.

    Recent research has documented that affect plays a crucial role in risk perception. When no information about numerical risk estimates is available (e.g., probability of loss or magnitude of consequences), people may rely on positive and negative affect toward perceived risk. However, determinants of affective reactions to risks are poorly understood. In a series of three experiments, we addressed the question of whether and to what degree mental imagery eliciting negative affect and stress influences risk perception. In each experiment, participants were instructed to visualize consequences of risk taking and to rate riskiness. In Experiment 1, participants who imagined negative risk consequences reported more negative affect and perceived risk as higher compared to the control condition. In Experiment 2, we found that this effect was driven by affect elicited by mental imagery rather than its vividness and intensity. In this study, imagining positive risk consequences led to lower perceived risk than visualizing negative risk consequences. Finally, we tested the hypothesis that negative affect related to higher perceived risk was caused by negative feelings of stress. In Experiment 3, we introduced risk-irrelevant stress to show that participants in the stress condition rated perceived risk as higher in comparison to the control condition. This experiment showed that higher ratings of perceived risk were influenced by psychological stress. Taken together, our results demonstrate that affect-laden mental imagery dramatically changes risk perception through negative affect (i.e., psychological stress).

    Full Text Available Alcohol is the most widely used drugs in World wide so it is in Colombia too. The United Nations Organization (UN report on substance abuse 2004, esteem that 2.6000 millions of persons used alcohol occasional, habitual, abuse or addictive way. In Colombia, RUMBOS, the presidential office for drugs addictions esteem that 89.7 % of the students in universities were habitual consumer of alcohol. Alcohol is the first psicoactivas substances use for people than after use illegal substances. When ethyl alcohol is used in permanent and frequent way produced acute and chronic adverses effect on the health. The long run alcohol abusers has adverse effect in the nutricions, neurological, hepatic and teratogenic. The neurological, gastrointestinal, endocrine and acid-base equilibrium area affected in acute ways principally. The social aspects in quite important too alcohol has been related to interfamiliar violence, traffic accidents and violence in general. The high incidence in use and consumption, its toxic effect over human health, its negative social effect and the fact that it´s a legal and social accept substance made alcohol and real public health problem. Its necessary to say "be careful with alcohol in general"

  11. Redefining the issues of risk and public acceptance

    A conceptual framework is proposed within which the notion of risk as normally used in risk assessment (RA) could be enlarged in line with the real substance of social issues of technology policy, to help avoid RA's threatened irrelevance to social decision making. It is argued that the frequent organizational incoherence and thus the unviability of modern technology arises from 'social alienation' between the innovation-commitment phase and the implementation of the technology in society. The roles of technical elites and of particular concepts of technology in this alienation are emphasized. One of the case studies deals with 'Nuclear power - myths of scientific and organizational realism' and discusses the UK nuclear 'programme' and the Three Mile Island accident. (author)

    Chemoprevention is an option for women who are at increased risk of breast cancer (five year risk ≥1.7%). It is uncertain, however, how often women accept and complete five years of therapy and whether clinical or demographic factors predict completion. Medical records were abstracted for 219 women whose five year risk of breast cancer was ≥1.7% and who were offered chemoprevention while attending a high risk breast clinic at the Moffitt Cancer Center. We examined the likelihood of accepting chemoprevention and completing five years of therapy, and potential clinical and demographic predictors of these outcomes, using multivariable logistic regression and survival analysis models. There were 118/219 women (54.4%) who accepted a recommendation for chemoprevention and began therapy. The likelihood of accepting chemoprevention was associated with lifetime breast cancer risk and was higher for women with specific high risk conditions (lobular carcinoma in situ and atypical ductal hyperplasia). Women with osteoporosis and those that consumed alcohol were also more likely to accept medication. There were 58/118 (49.2%) women who stopped medication at least temporarily after starting therapy. Based on survival curves, an estimated 60% of women who begin chemoprevention will complete five years of therapy. A substantial percentage of women at increased risk of breast cancer will decline chemoprevention and among those that accept therapy, approximately 40% will not be able to complete five years of therapy because of side effects.

  13. Nuclear waste in the Pacific: perceptions of the risks

    Childs, I.R.W.

    1984-01-01

    This dissertation examines the problem of the disposal of high-level nuclear waste in the Pacific region. There is a consensus of scientific opinion that the technical difficulties in waste disposal can be overcome. The most acceptable solution seems to be the multi-barrier approach for deep land-based geologic disposal. A questionnaire survey on the perception of nuclear and other hazards, conducted with student populations in Japan and Australia, and a survey of reporting of nuclear events in Pacific newspapers over the period 1946 to the 1980s, reveal that the image of nuclear weapons dominates public views on the risks associated with waste disposal in Australia, Japan, and the Pacific Islands. The problem of finding a suitable site for a nuclear waste disposal facility is to a large extent political. The capacity of anti-nuclear groups to influence waste disposal policies in Australia, Japan, and the Pacific Islands is examined. Current public attitudes toward nuclear waste disposal will delay the further development of activities connected with the nuclear fuel cycle, but this may change over time if the connection between commercial nuclear power and nuclear weapons can be severed more effectively. The most urgent problem in the region is the waste from the ambitious nuclear power programs of Japan, South Korea, and Taiwan

    Risk perception is judgment that people make about the characteristics and severity of risks, in last few years risk perception studies focused on provide cognitive elements to communication experts responsible in order to design citizenship information and awareness appropriate strategies. Several authors in order to determine natural hazards risk (Seismic, landslides, cyclones, flood, Volcanic) perception used questionnaires as tool for providing reliable quantitative data and permitting comparison the results with those of similar surveys. In Italy, risk perception studies based on surveys, were also carried out in order to investigate on national importance Natural risk, in particular on Somma-Vesuvio and Phlegrean Fields volcanic Risks, but lacked risk perception studies on local situation distributed on whole national territory. National importance natural hazard were frequently reported by national mass media and there were debate about emergencies civil protection plans, otherwise could be difficult to obtain information on bonded and regional nature natural hazard which were diffuses along National territory. In fact, Italian peninsula was a younger geological area subjected to endogenous phenomena (volcanoes, earthquake) and exogenous phenomena which determine land evolution and natural hazard (landslide, coastal erosion, hydrogeological instability, sinkhole) for population. For this reason we decided to investigate on natural risks perception in different Italian place were natural hazard were taken place but not reported from mass media, as were only local relevant or historical event. We carried out surveys in different Italian place interested by different types of natural Hazard (landslide, coastal erosion, hydrogeological instability, sinkhole, volcanic phenomena and earthquake) and compared results, in order to understand population perception level, awareness and civil protection exercises preparation. Our findings support that risks

    Full Text Available BACKGROUND: How accurately do people perceive extreme water speeds and how does their perception affect perceived risk? Prior research has focused on the characteristics of moving water that can reduce human stability or balance. The current research presents the first experiment on people's perceptions of risk and moving water at different speeds and depths. METHODS: Using a randomized within-person 2 (water depth: 0.45, 0.90 m ×3 (water speed: 0.4, 0.8, 1.2 m/s experiment, we immersed 76 people in moving water and asked them to estimate water speed and the risk they felt. RESULTS: Multilevel modeling showed that people increasingly overestimated water speeds as actual water speeds increased or as water depth increased. Water speed perceptions mediated the direct positive relationship between actual water speeds and perceptions of risk; the faster the moving water, the greater the perceived risk. Participants' prior experience with rip currents and tropical cyclones moderated the strength of the actual-perceived water speed relationship; consequently, mediation was stronger for people who had experienced no rip currents or fewer storms. CONCLUSIONS: These findings provide a clearer understanding of water speed and risk perception, which may help communicate the risks associated with anticipated floods and tropical cyclones.

    Development of acceptable risk criteria for nuclear waste management requires the translation of publicly determined goals and objectives into definitive issues which, in turn, require resolution. Since these issues are largely of a subjective nature, they cannot be resolved by technological methods. Development of acceptable risk criteria might best be accomplished by application of a systematic methodology for the optimal implementation of subjective values. Multi-attribute decision analysis is well suited for this purpose

    2012-01-01

    Background Advanced maternal age (AMA) is associated with several adverse pregnancy outcomes, hence these pregnancies are considered to be “high risk.” A review of the empirical literature suggests that it is not clear how women of AMA evaluate their pregnancy risk. This study aimed to address this gap by exploring the risk perception of pregnant women of AMA. Methods A qualitative descriptive study was undertaken to obtain a rich and detailed source of explanatory data regarding perceived pregnancy risk of 15 women of AMA. The sample was recruited from a variety of settings in Winnipeg, Canada. In-depth interviews were conducted with nulliparous women aged 35 years or older, in their third trimester, and with singleton pregnancies. Interviews were recorded and transcribed verbatim, and content analysis was used to identify themes and categories. Results Four main themes emerged: definition of pregnancy risk, factors influencing risk perception, risk alleviation strategies, and risk communication with health professionals. Conclusions Several factors may influence women's perception of pregnancy risk including medical risk, psychological elements, characteristics of the risk, stage of pregnancy, and health care provider’s opinion. Understanding these influential factors may help health professionals who care for pregnant women of AMA to gain insight into their perspectives on pregnancy risk and improve the effectiveness of risk communication strategies with this group.

    A controversy over the safety of nuclear energy has grown in the U.S. since about 1970 and has now spread to near worldwide proportions. This controversy has been fueled by a variety of issues. Initially in the U.S. the most prominent issue concerned the degree of hazard of low-level radiation, in particular that associated with the nuclear fuel cycle. Since then, attention has shifted successively to the reliability of emergency core cooling systems, the longevity of nuclear wastes, the possible misuse of radioactivity by terrorists and the potential for diversion of nuclear-power-produced plutonium to weapons fabrication. Underlying each of these issues has been the implication that the employment of nuclear power will entail an unacceptable risk to the public. A reasonable perspective in this regard is a yearly risk of 1 x 10 -6 compared to the level of natural hazards such as earthquakes, floods, hurricanes, and tornados. Following a satisfactory demonstration of the safety of nuclear energy, hopefully the nuclear argument could be terminated. Society could then move on to the real issues affecting energy, population and quality of life

    Natalizumab (NAT) is associated with the risk of progressive multifocal leukoencephalopathy (PML). Risk stratification algorithms have been developed, however, without detectable reduction of PML incidence. To evaluate to which extent patients and physicians understand and accept risks associated with NAT treatment. Prospective observational cohort study in German MS centers (n=73) among NAT-treated MS patients (n=801) and their neurologists (n=99). Patients included in this study had mean disease duration of 10.2years and a mean NAT treatment duration of 24months. More than 90% of patients and physicians voted for shared decision making or an informed choice decision making approach. Patients and physicians perceived a similar threat from MS as serious disease and both overestimated treatment benefits from NAT based on trial data. Men perceived MS more severe than women and perception of seriousness increased with age in both groups and in patients as well with increasing disability. Although patients evaluated their PML risk higher, their risk acceptance was significantly higher than of their neurologists. Risk stratification knowledge was good among neurologists and significantly lower among patients. While patients and physicians seem to have realistic risk perception of PML and knowledge of risk stratification concepts, the threat of MS and the perception of treatment benefits may explain the ongoing high acceptance of PML risk.

Public acceptance is determinant to the deployment of an undertaking of this size. A major concern regarding the use of nuclear energy are the problems related to safe management of the radioactive waste. For effective communication between decision makers and the public, a mutual understanding of views, as well as attitudes towards risk, is needed. The use of opinions polls is necessary in order to achieve it. This work aims to point out the major aspects to be approached by an opinion poll for the study of risk perception on the candidate regions for repository construction.

    Background Muay Thai is a style of kickboxing that allows full-contact blows to an unprotected head, torso and legs, and, as in any combat sport, there is an inherent risk of injury. Previous observational studies have shown there is a substantial risk of injury in competitive kickboxing. None of these studies, however, have investigated the potential role of psychological risk factors and, consequently, little is known about the perception of injury risk among these athletes.

    In industry, because of retirement of postwar baby-boom generation and decreasing labor accident by improvement in facilities, diminished worker's risk perception is concerned about. Although hazard prediction activity (KY: Kiken-Yochi) is carried out for improvement of workers' risk perception in sites, it is get into a rut not to estimate the effects of the activity. Then the purpose of this study is to examine the possibility of measuring and estimating individual inherent risk perception not depending on the experiences and knowledge, and to confirm the effects of the experiences and knowledge on one's risk perception. Eleven subjects were requested to detect the hazards and to estimate the results and the extents of damage in the three films (1: working at an office (all subjects had the experience), 2: feeding at the GS (gas station) (half of them had the experience), 3: overhauling a valve (no one had the experience)) that were included in some hazards. The rate of hazards detection and the accuracies of 5 categories, that were hazards, results, damage of human, damage of objects or facilities and coping, were calculated. The experience of feeding had effects on the rate of hazards detection and some of the accuracies at the film of feeding at the GS. Also, all of indices were significantly lower at the firm of overhauling a valve than the firm of working at an office. These results showed that the experiences and knowledge were affected on one's risk perception. Meanwhile, the similarity of the tendency to the rate of hazards detection and the accuracies between 2 firms except for the firm of feeding was found by means of the ordinal correlation. The result showed that it will be able to measure the individual inherent risk perception from the number of hazards detection and the depth of the context.

    2016-01-01

    Anxiety prepares an organism for dealing with threats by recruiting cognitive resources to process information about the threat, and by engaging physiological systems to prepare a response. Heightened trait anxiety is associated with biases in both these processes: high trait-anxious individuals tend to report heightened risk perceptions, and…

    Full Text Available In average 26 death events in mountaineering per year for the time span from 2003 to 2012 is reported. The number of women dying during the mountaineering is significantly smaller than males (3.5 deaths male for one female death. This study aims to analyze the differences of risk perception based on gender and provide recommendations as education basic to prevent accidents in mountaineering. This study utilizes the Kruskal-Wallis test and the Delphi Method. A total of 200 mountaineer respondents (100 males and 100 females participated in this study. The independent variable in this study was gender. The dependent variable was risk perception including perception toward the serious accident, perception toward the probability of accident event as well as anxiety level and perception of efficacy and self-efficacy. The study result showed that the risk perception of women is higher than men with significant difference (p-value = 0.019. The recommendations from Delphi method result are by developing a positive mental attitude, showing about the risks that exist in nature, implementing Cognitive Behaviour Therapy (CBT to raise awareness of the safety of ownself, following the climbing or mountaineer school, and using instructors to give lessons about safety in outdoor activities.

    Hardy, Terry L.

    2005-12-01

    A number of inventors and entrepreneurs are currently attempting to develop and commercially operate reusable launch vehicles to carry voluntary participants into space. The operation of these launch vehicles, however, produces safety risks to the crew, to the space flight participants, and to the uninvolved public. Risk communication therefore becomes increasingly important to assure that those involved in the flight understand the risk and that those who are not directly involved understand the personal impact of RLV operations on their lives. Those involved in the launch vehicle flight may perceive risk differently from those non-participants, and these differences in perception must be understood to effectively communicate this risk. This paper summarizes existing research in risk perception and communication and applies that research to commercial reusable launch vehicle operations. Risk communication is discussed in the context of requirements of United States law for informed consent from any space flight participants on reusable suborbital launch vehicles.

    Purpose The purpose of this study was to describe perception of risk for developing diabetes among foreign-born Spanish-speaking U.S. Latinos. Methods Participants (N=146), recruited at food-pantry distribution events and free clinics, were surveyed using the Risk Perception Survey for Developing Diabetes in Spanish. Type 2 diabetes risk factors measured included: Body Mass Index, physical activity, and Hemoglobin A1C. Results Sample characteristics were mean age 39.5 (±9.9) years old, 58% with less than a high school graduate level education, and 65% with a family income less than $15,000/year. Prevalence of risk factors was 81% overweight or obese, 47% risk for developing diabetes. In univariate logistic regression analyses, 9 of 18 potential variables were significant (pperception of risk. When these 9 variables were entered into a multiple logistic regression model, 5 were significant predictors of perception of risk: history of gestational diabetes, ≥ high school graduate, optimistic bias, worry, and perceived personal disease risk. Conclusions This is the first study using the Risk Perception Survey for Developing Diabetes in Spanish in this population and reveals factors that influence perception of risk for developing diabetes. The results can be used to promote culturally acceptable type 2 diabetes primary prevention strategies and provide a useful comparison to other populations. PMID:27150605

    Research by cognitive and social psychologists has demonstrated that when lay persons make estimates of risks they do not merely calculate in terms of probabilistic information. People tend to construe the risk in accordance with other schemata. The Psychometric Paradigm (Slovic et. al., 1980), found out two main dimensions in the perception of risk: the Dread and the Familiarity-Voluntariness factors. This paper presents some of the key findings of a comparative Latin-American study on radiological risk perception in the health area. The main objective is to check whether or not the Dread and the Familiarity-Voluntariness dimensions explain the perception of risk in this specific context. A questionnaire was distributed to outpatient samples from ten countries: Argentine, Brazil, Colombia, Cuba, Ecuador, Mexico, Panama, Peru, Uruguay, and Spain, thanks to the collaboration of the different National Radioprotection Societies of the above mentioned countries, and of other concerned professionals (in case they didn't have any association at the time). A list of 22 risks, including both radiological and non-radiological ones, were evaluated on two rating scales: possibility and seriousness. Factor analysis, both exploratory and confirmatory, as well as Multidimensional Scaling will be used for the data analysis. The paper will discuss the main cross-cultural differences with regard to the structure of risk perception. The peculiarities of the health related risks will be emphasised. (author)

    Technological progress and its impacts on humankind has caused an increasing awareness of risk, and objective, statistical estimations are often inadequate to alleviate the public's fright and fear. Research on risk perception using psychological and sociological approaches is trying to bridge this gap. As a first step, a distinction must be made between the technical definition of risk (probability x consequences) and the social definition, in which additional parameters (source, dimensions, timeframe, exposure) need to be included. The methodology of risk assessment, though objective by design, is limited in the interpretability of its results, if the calculation of consequences does not take public perceptions and social effects into account. The problems and advantages of risk assessment are discussed, and the key questions for risk perception research are presented. Various techniques are available to study risk perception and attitudes towards risk; selection of a specific technique is determined by the objective of the research, namely sociological implications or psychological cognitions. Several empirical studies in both areas are presented and the results discussed.

    Full Text Available Environmental events such as natural disasters may influence the public's affective reactions and decisions. Shortly after the 2004 Tsunami disaster we assessed how affect elicited by thinking about this disaster influenced risk perceptions and future time perspective in Swedish undergraduates not directly affected by the disaster. An experimental manipulation was used to increase the salience of affect associated with the disaster. In Study 1 we found that participants reminded about the tsunami had a sense that their life was more finite and included fewer opportunities than participants in the control condition (not reminded about the tsunami. In Study 2 we found similar effects for risk perceptions. In addition, we showed that manipulations of ease-of-thought influenced the extent to which affect influenced these risk perceptions, with greater ease of thoughts being associated with greater perceived risks.

    Starting with 2000, the expert group Society and Policy Support carries out research on various aspects of risk governance. Measuring several risk perception items at regular intervals with the Belgian population is an important part of this research. SCK-CEN has organised a first risk perception barometer in 2002 and a second one in 2006. The 2006 barometer is based on 1063 Computer Assisted Personal Interviews, with a duration of approximately 35 minutes. The large scale of the survey ensures that general trends can be detected and allows specific and detailed analysis on subgroups of the population. Besides the classical background variables used to obtain a sample representative for the Belgian 18+ population (age, language, habitat, gender and social class), several questions were included assessing the sociological context and the psychological personality profile. A series of questions on risk perception, confidence in authorities and specific nuclear topics were repeated in 2006 and constitute a fixed core, allowing comparison over time in Belgium, as well as with the results from the IRSN French barometer. In addition, a number of topics such as acceptance of legal norms and management options for radioactively contaminated milk, energy, nuclear waste and the perception of the Chernobyl accident were covered in detail in the 2006 edition of the SCK-CEN barometer

    To study the homogeneity and influences on scientists' perspectives of environmental risks, the authors have examined similarities and differences in risk perceptions, particularly regarding nuclear wastes, and policy preferences among 1011 scientists and engineers. Significant differences (p<0.05) were found in the patterns of beliefs among scientists from different fields of research. In contrast to physicists, chemists, and engineers, life scientists tend to: (a) perceive the greatest risks from nuclear energy and nuclear waste management; (b) perceive higher levels of overall environmental risk; (c) strongly oppose imposing risks on unconsenting individuals; and (d) prefer stronger requirements for environmental management. On some issues related to priorities among public problems and calls for government action, there are significant variations among life scientists or physical scientists. It was also found that-independently of field of research-perceptions of risk and its correlates are significantly associated with the type of institution in which the scientist is employed. Scientists in universities or state and local governments tend to see the risks of nuclear energy and wastes as greater than scientists who work as business consultants, for federal organizations, or for private research laboratories. Significant differences also are found in priority given to environmental risks, the perceived proximity of environmental disaster, willingness to impose risks on an unconsenting population, and the necessity of accepting risks and sacrifices. 33 refs., 3 figs., 9 tabs

    Social considerations significantly influence daily purchase decisions, and the perception of social risk (i.e., the anticipated disapproval of others) is crucial in dissuading consumers from making purchases. However, the neural basis for consumers' perception of social risk remains undiscovered, and this novel study clarifies the relevant neural processes. A total of 26 volunteers were scanned while they evaluated purchase intention of products (purchase intention task) and their anticipation of others' disapproval for possessing a product (social risk task), using functional magnetic resonance imaging (fMRI). The fMRI data from the purchase intention task was used to identify the brain region associated with perception of social risk during purchase decision making by using subjective social risk ratings for a parametric modulation analysis. Furthermore, we aimed to explore if there was a difference between participants' purchase decisions and their explicit evaluations of social risk, with reference to the neural activity associated with social risk perception. For this, subjective social risk ratings were used for a parametric modulation analysis on fMRI data from the social risk task. Analysis of the purchase intention task revealed a significant positive correlation between ratings of social risk and activity in the anterior insula, an area of the brain that is known as part of the emotion-related network. Analysis of the social risk task revealed a significant positive correlation between ratings of social risk and activity in the temporal parietal junction and the medial prefrontal cortex, which are known as theory-of-mind regions. Our results suggest that the anterior insula processes consumers' social risk implicitly to prompt consumers not to buy socially unacceptable products, whereas ToM-related regions process such risk explicitly in considering the anticipated disapproval of others. These findings may prove helpful in understanding the mental

    Despite substantial public health efforts to increase HIV testing, testing rates have plateaued in many countries and rates of repeat testing for those with ongoing risk are low. To inform policies aimed at increasing uptake of HIV testing, we identified characteristics associated with individuals' willingness-to-accept (WTA) an HIV test in a general population sample and among two high-risk populations in Moshi, Tanzania. In total, 721 individuals, including randomly selected community members (N = 402), female barworkers (N = 135), and male Kilimanjaro mountain porters (N = 184), were asked in a double-bounded contingent valuation format if they would test for HIV in exchange for 2000, 5000 or 10,000 Shillings (approximately $1.30, $3.20, and $6.40, respectively). The study was conducted between September 2012 and February 2013. More than one quarter of participants (196; 27 %) stated they would be willing to test for Tanzania Shilling (TSH) 2000, whereas one in seven (98; 13.6 %) required more than TSH 10,000. The average WTA estimate was TSH 4564 (95 % Confidence Interval: TSH 4201 to 4927). Significant variation in WTA estimates by gender, HIV risk factors and other characteristics plausibly reflects variation in individuals' valuations of benefits of and barriers to testing. WTA estimates were higher among males than females. Among males, WTA was nearly one-third lower for those who reported symptoms of HIV than those who did not. Among females, WTA estimates varied with respondents' education, own and partners' HIV testing history, and lifetime reports of transactional sex. For both genders, the most significant association was observed with respondents' perception of the accuracy of the HIV test; those believing HIV tests to be completely accurate were willing to test for approximately one third less than their counterparts. The mean WTA estimates identified in this study suggest that within the study population, incentivized universal HIV

    This paper studies how individuals update subjective risk perceptions in response to hurricane track forecast information, using a unique data set from an event market, the Hurricane Futures Market (HFM). We derive a theoretical Bayesian framework which predicts how traders update their perceptions of the probability of a hurricane making landfall in a certain range of coastline. Our results suggest that traders behave in a way consistent with Bayesian updating but this behavior is based on t...

    Air pollution is among the leading global risks for mortality and responsible for increasing risk for chronic diseases. Community perceptions on exposure are critical in determining people’s response and acceptance of related policies. Therefore, understanding people’ perception is critical in informing the design of appropriate intervention measures. The aim of this paper was to establish levels and associations between perceived pollution and health risk perception among slum residents. A cross-sectional study of 5,317 individuals aged 35+ years was conducted in two slums of Nairobi. Association of perceived score and individual characteristics was assessed using linear regression. Spatial variation in the perceived levels was determined through hot spot analysis using ArcGIS. The average perceived air pollution level was higher among residents in Viwandani compared to those in Korogocho. Perceived air pollution level was positively associated with perceived health risks. The majority of respondents were exposed to air pollution in their place of work with 66% exposed to at least two sources of air pollution. Less than 20% of the respondents in both areas mentioned sources related to indoor pollution. The perceived air pollution level and related health risks in the study community were lowamong the residents indicating the need for promoting awareness on air pollution sources and related health risks.

  11. Perceptions and Acceptance of Desalinated Seawater for Irrigation: A Case Study in the Níjar District (Southeast Spain

    2017-06-01

    Full Text Available In the context of increasing demand for irrigation water—but, at the same time, with the constraints in the supply from traditional resources—desalinated seawater has been recognized as one of the alternative sources of water to increase the supply for agricultural irrigation. However, its use among farmers has not yet started to expand. Policy makers need to understand what is causing the low acceptance levels of farmers, and how their attitudes could be improved. This is the first study that has conducted an analysis of farmers’ perceptions and acceptance of the use of desalinated seawater for irrigation. The study is based on collected data from a survey completed by farmers in southeastern Spain who do not use desalinated seawater. The main results indicate that desalinated seawater as a water supply source has the lowest acceptance level for farmers. Barriers for its use are price, the need for additional fertilization, and the perception that it would negatively affect the yield and crop quality. The farmers’ general level of knowledge about the impact of using desalinated seawater in agriculture is extremely low. Furthermore, farmers consider it a priority that their startup investment should be subsidized and that water prices should be reduced. Based on the study findings, this paper makes recommendations for the decision-making process in order to improve farmers’ acceptance levels.

    2015-11-01

    Clinical risk stratification models, such as the CHA2DS2-VASc, are used to assess stroke risk in atrial fibrillation (AF) patients. No study has yet investigated whether and to which extent these patients have a realistic perception of their personal stroke risk. The purpose of this study was to investigate and describe the association between AF patients' stroke risk perception and clinical stroke risk. In an observational cross-sectional study design, we surveyed 178 AF patients with a mean age of 70.6 years (SD 8.3) in stable anticoagulant treatment (65% treatment duration >12 months). Clinical stroke risk was scored through the CHA2DS2-VASc, and patients rated their perceived personal stroke risk on a 7-point Likert scale. There was no significant association between clinical stroke risk assessment and patients' stroke risk perception (rho = .025; P = .741). Approximately 60% of the high-risk patients had an unrealistic perception of their own stroke risk, and there was no significant increase in risk perception from those with a lower compared with a higher risk factor load (χ(2) = .010; P = .522). Considering possible negative implications in terms of lack of motivation for lifestyle behavior change and adequate adherence to the treatment and monitoring of vitamin K antagonist, the apparent underestimation of risk by large subgroups warrants attention and needs further investigation with regard to possible behavioral consequences.

    Abstract Differences in risk perceptions of public health and food safety hazards in various poultry husbandry systems by various stakeholder groups, may affect the acceptability of those husbandry systems. Therefore, the objective was to gain insight into risk perceptions of citizens, poultry farmers, and poultry veterinarians regarding food safety and public health hazards in poultry husbandry systems, and into factors explaining these risk perceptions. We surveyed risk perceptions of Campylobacter contamination of broiler meat, avian influenza introduction in laying hens, and altered dioxin levels in eggs for the most commonly used broiler and laying hen husbandry systems in Dutch citizens (n = 2,259), poultry farmers (n = 100), and poultry veterinarians (n = 41). Citizens perceived the risks of the three hazards in the indoor systems higher and in the outdoor systems lower than did the professionals. Citizens reported higher concerns regarding aspects reflecting underlying psychological factors of risk perception compared to professionals. Professionals indicated a relatively low level of personal control, which might imply risk denial. Of the socio-demographic characteristics, gender and childhood residence were associated with risk perceptions. The influence of other factors of risks perception are discussed. It is suggested that risk perceptions of all stakeholder groups are influenced by affect, stigma, and underlying values. To adapt current or new husbandry systems that can count on societal support, views of key stakeholders and multiple aspects such as animal welfare, public health, food safety, and underlying values should be considered integrally. When trade-offs, such as between animal welfare and public health have to be made, insight into underlying values might help to find consensus among stakeholders. PMID:29161444

    In this paper, the authors discuss insights gained from evaluating changes to plant design and operational practices. Evaluation of a change is performed in order to provide an answer to two fundamental questions: what is the impact and is the impact acceptable? In order to determine 'the acceptability of an impact', the risk-based technologies today provide various ranking schemes. They are based on the existing IPE studies or PSA models and use of standard risk importance measures. In 'ad hoc' applications of risk importance measures, the specific nature of the analyzed change is often neglected. This paper attempts to capture the most common problems in the application of importance measures, and defines the limits of this application. The authors' position is that the use of risk importance information as the sole basis to accept or reject with ranking results, after the basis for the rank is meaningfully established. (author)

  17. PARALLELS OF RADIATION- AND FINANCIAL-RISK MANAGEMENT ON PUBLIC ACCEPTANCE

    2010-01-04

    The financial collapse of 2007 provides an opportunity for a cross-discipline comparison of risk assessments. Flaws in financial risk assessments bear part of the blame for the financial collapse. There may be a potential for similar flaws to be made in radiological risk assessments. Risk assessments in finance and health physics are discussed in the context of a broader view of the risk management environment. Flawed risk assessments can adversely influence public acceptance of radiological technologies, so the importance of quality is magnified.

    The resilience of communities against natural hazards is largely influenced by how the individuals perceive risk. A good understanding of people's risk perception, awareness and hazard knowledge is crucial for developing and improving risk management and communication strategies between authorities and the affected population. A lot of research has been done in investigating the social aspects of risks to natural hazards by means of interviews or questionnaires. However, there is still a lack of research in the investigation of the influence of the spatial distance to a hazard event on peoples risk perception. While the spatial dimension of a natural hazard event is always assessed in works with a natural science approach, it is often neglected in works on social aspects of natural hazards. In the present study, we aimed to overcome these gaps by combining methods from different disciplines and assessing and mapping the spatial pattern of risk perception through multivariate statistical approaches based on empirical data from questionnaires. We will present results from a case study carried out in Badia, located in the Province of South Tyrol- Italy, where in December 2012 a landslide destroyed four residential buildings and led to the evacuation of 36 people. By means of questionnaires distributed to all adults living in the case study area we assessed people's risk perception and asked respondents to allocate their place of residence on a map of the case study area subdivided in 7 zones. Based on the data of the questionnaire results we developed a risk perception factor in order to express various assessed aspects linked to risk perception with one metric. We analyzed and mapped this factor according to the different zones reflecting the spatial distance to the event. Furthermore, a cluster analysis identified various risk behavior profiles within the population. We also investigated the spatial patterns of these risk profiles. We revealed that the residential

    This present work contains the study of risk perception in different areas of interaction. For it was made an analysis using methodology previously recognized and tested: a systematic review in the search for better understanding of the perception of risk in the nuclear area. Through this study it was possible to understand the potential of the systematic review as a tool for information that encompass the perception of risk as a whole. Making it possible to trace parameters to find out why the world's people have an aversion to certain matters relating to nuclear energy. Considering that if you can understand what drives the people has disgust on nuclear area, it is probably possible to create alternatives to remedy this lack of information and knowledge about the area. Causing the population to realize the benefits that nuclear power brings to people. (author)

  1. The Meaning and Process of Pain Acceptance. Perceptions of Women Living with Arthritis and Fibromyalgia

    Full Text Available BACKGROUND: Within the past 10 years, cognitive-behavioural pain management models have moved beyond the traditional focus on coping strategies and perceived control over pain, to incorporate mindfulness-and acceptance-based approaches. Pain acceptance is the process of giving up the struggle with pain and learning to live life despite pain. Acceptance is associated with lower levels of pain, disability and psychological distress. Relatively little is known, however, about how patients arrive at a state of acceptance without the aid of therapy.

    Objectives Falls are a leading cause of injury at work, and slipping is the predominant cause of falling. Prior research has suggested a modest correlation between objective measures (such as coefficient of friction, COF) and subjective measures of slipperiness (such as worker perceptions) in the workplace. However, the degree of association between subjective measures and the actual risk of slipping at the workplace is unknown. This study examined the association between perception of slipperiness and the risk of slipping. Methods 475 workers from 36 limited-service restaurants participated in a 12-week prospective cohort study. At baseline, demographic information was collected, participants rated floor slipperiness in eight areas of the restaurant, and work environment factors, such as COF, were measured. Restaurant-level and area-level mean perceptions of slipperiness were calculated. Participants then reported their slip experience at work on a weekly basis for the next 12 weeks. The associations between perception of slipperiness and the rate of slipping were assessed. Results Adjusting for age, gender, body mass index, education, primary language, mean COF, use of slip-resistant shoes, and restaurant chain, each 1-point increase in mean restaurant-level perception of slipperiness (4-point scale) was associated with a 2.71 times increase in the rate of slipping (95% CI 1.25 to 5.87). Results were similar for area-level perception within the restaurant (rate ratios (RR) 2.92, 95% CI 2.41 to 3.54). Conclusions Perceptions of slipperiness and the subsequent rate of slipping were strongly associated. These findings suggest that safety professionals, risk managers and employers could use aggregated worker perceptions of slipperiness to identify slipping hazards and, potentially, to assess intervention effectiveness.

  3. Risk perceptions and technological hazards: a contextual view

    Full text of publication follows: the study of public perceptions of risk has given rise to a number of different (and sometimes conflicting) perspectives. Although the differences between these approaches are not trivial, recent reviews have suggested that there may be some points of convergence. In particular, recent work within the different traditions has emphasised the importance of factors such as trust and power for understanding public perceptions of risk. These factors take us beyond the characteristics of the risks themselves, which were the focus of influential work in the psychometric tradition and into a consideration of the social and cultural context within which potentially hazardous technologies are encountered and evaluated. In this paper we examine the way in which the lay public understand and respond to a particular class of technological risks - those associated with site-based major accident hazards. On the basis of empirical research, we argue that an appreciation of the different contexts within which citizens encounter such risks is crucial to understanding the dynamics of public concerns. We illustrate our argument by examining the different ways in which contextual factors influence perceptions. The discussion draws upon a recently completed study of public perceptions of the risks at seven major hazard sites in the UK, which was funded the by UK Health and Safety Executive. (authors)

    According to recent studies, Spanish adolescents show low perception of risk in alcohol consumption. The current study aims to analyze the factors that favor this low perception based on the opinion of a group of 32 professional experts on adolescence, family, school, mass media, and local policies. A qualitative methodology was used, based on Grounded Theory, using information from 5 focus groups guided by semi-structured interviews. Twelve factors or subcategories were identified, grouped in 4 general categories: short-term risk, immediacy, and perception of invulnerability ("adolescent thinking" category); benevolent view of alcohol, normalization of consumption, and alcohol-entertainment binomial ("social norms" category); parents' habitual consumption, verbal/non-verbal inconsistency in parental model, risk-free consumption depicted in the mass media, consumption with positive results in the media ("social models" category); and excessive health content, long-term risk ("preventive discourse" category). After discussing the results in the context of the current scientific literature, the article offers various proposals for increasing risk perception in adolescents: stronger impact of contents on short-term risks of alcohol; educational strategies targeted to adolescents to include agents of socialization, especially parents; and policies centered on the substance and reduction of supply.

    In this narrative review, a brief summary of theoretical approaches to risk perception is followed by an analysis of some of the special factors influencing risk perception and risk communication in sub-Saharan Africa. Examples of recent and emergent local medicines and vaccine controversies in several countries are given along with evidence and analysis of how they were managed. These demonstrate, among other things, the extent to which ethnic, religious and cultural issues influence popular perception, and the power of rumour and anecdote in shaping public opinion and official responses to events. Where safety monitoring systems exist, they are in their infancy, with limited capacity for data collection, credible scientific review, effective public communication and robust crisis management. Although increasing democratic freedoms, including less restricted media, and evolving health systems are addressing the challenges and give hope for further progress, there are still deep and intractable issues that inhibit transparent and effective risk communication and stand in the way of African populations comprehending medicines and their risks in safer and more balanced ways. Some proposals for future change and action are offered, including the pursuit of a deeper understanding of local and national values, assumptions and beliefs that drive risk perception; tailoring public health planning and communications to specifically-targeted regions and populations; strengthening of safety surveillance and data-collection systems; giving higher priority to medicines safety issues in healthcare training and public education.

    Effective risk communication in transfusion medicine is important for health-care consumers, but understanding the numerical magnitude of risks can be difficult. The objective of this study was to determine the effect of a visual risk communication tool on the knowledge and perception of transfusion risk. Laypeople were randomly assigned to receive transfusion risk information with either a written or a visual presentation format for communicating and comparing the probabilities of transfusion risks relative to other hazards. Knowledge of transfusion risk was ascertained with a multiple-choice quiz and risk perception was ascertained by psychometric scaling and principal components analysis. Two-hundred subjects were recruited and randomly assigned. Risk communication with both written and visual presentation formats increased knowledge of transfusion risk and decreased the perceived dread and severity of transfusion risk. Neither format changed the perceived knowledge and control of transfusion risk, nor the perceived benefit of transfusion. No differences in knowledge or risk perception outcomes were detected between the groups randomly assigned to written or visual presentation formats. Risk communication that incorporates risk comparisons in either written or visual presentation formats can improve knowledge and reduce the perception of transfusion risk in laypeople.

    Like every year, this report presents and comments the results of an opinion survey on risks, and more particularly on nuclear and radiological risks. The first part addresses the current concerns of French people (the main concerns in the present society and with respect to the environment, how science is considered). The second part addresses the opinion on expertise (who should control a hazardous installation, the role and image of experts, the access to expertise files, the perception of pluralist bodies). The third part examines the reaction of people in front of 33 different hazardous situations (risks to which people feel being exposed, confidence in authorities, confidence in information on hazards, hierarchy of 33 situations and relationship with installation acceptability). The fourth part addresses the nuclear issue (nuclear risk, ability and credibility of nuclear actors, the Chernobyl accident, radioactive wastes, demand of information on the nuclear risk).

    2007-01-01

    We identify and explain factors that affected a community's perception of risk due to extensive industrial contamination and people's distrust of government agencies regarding the environmental investigations. Intrinsic bounded case study methodology was used to conduct research about extensive environmental contaminations due to activities of an oil refinery in North Casper, Wyoming, and the citizens' response. Data were collected from multiple sources that included public testimonies, observations, public hearings and meetings minutes, newspaper articles, archived records obtained from federal and state environmental and health agencies, as well as industry records obtained through Freedom of Information Act (FOIA) requests. The overarching theme that emerged was lack of trust due to several critical events and factors such as no response or delay in response time to community concerns, lack of transparency, perceived cover up, vague and fragmented communication by government and state officials, perception of pro-industry stance, and perceived unfair treatment. People's perception of environmental risks and their willingness to accept official explanations and outcomes of environmental investigations are strongly affected by their direct experiences with government agencies and the evidence of influence the powerful industries exert over relevant investigations. The government cannot successfully address public and community concerns about environmental health impacts of contaminations and in turn the public perception of risk unless it adopts and implements policies, procedures, and protocols that are clear, timely, transparent, and free from industry influence.

    In two experiments, the impact of shopping context on consumers' risk perceptions and regulatory focus was examined. We predicted that individuals perceive an online (vs. conventional) shopping environment as more risky and that an online shopping environment, by its risky nature, primes a prevention focus. The findings in Study 1 demonstrate these effects by using self-report measures for risk perception and prevention focus. In Study 2, we replicated these findings and demonstrated that the effect of an online shopping environment carries over to behavior in a domain unrelated to shopping.

    Previous research suggested that illness perceptions provide the basis for illness risk perceptions through an inductive reasoning process. This study aimed to assess the direction of relationships between illness and recurrence risk perceptions over time, among cardiac patients. A longitudinal study was conducted among 138 patients undergoing coronary angioplasty. Self-report questionnaires measured perceived recurrence risk and illness perceptions one day and one month after catheterisation. Cross-lagged Panel Model Analyses revealed that higher perceptions of timeline, consequences and emotional representations of illness at hospitalisation were associated with higher recurrence risk perceptions one month later. Perceived personal control was the only illness perception with bi-directional associations: higher perceived personal control at hospitalisation was associated with higher recurrence risk perceptions one month later; and higher recurrence risk perceptions at hospitalisation was associated with lower personal control one month later. The findings suggest that the associations between recurrence risk and illness perceptions can only partly be explained by inductive reasoning. Halo effects and defensive processes are suggested as complementary explanations for the observed associations between risk and illness perceptions.

    Public acceptance has become an important factor in nuclear power program particularly after Chernobyl accident and recent rapid democratization in Korea. Methods reflection public opinions in order to improve public acceptance are firstly to understand what the public think about nuclear power plant and secondly to find out the public preference values for its policies. For this purpose, simplified multi-attribute utility(MAU) model was applied to analyze the public perception for five power production system. And the conjoint analysis was applied to find out he quantitative values of public preferences for twelve policy alternatives to improve the safety and support communities surrounding nuclear power plants in Korea. To implement these perception and preference analyses, mail survey was conducted to the qualified sample who had the experience of visiting nuclear power plant. Diagnosis of their perception pattern for five power production systems was made by the simplified MAU model. Estimation of the quantitative preference values for potential policy alternatives was made by the conjoint measurement technique, which made it possible to forecast the effectiveness of each option. The results from the qualified sample and the methods used in this study would be helpful to set up new policy of nuclear power plant. 4 figs., 7 tabs., 18 refs. (Author)

  19. Risk perception of various technical options in the field of radioactive waste management

    1996-01-01

    The author's group had a wide ranging discussion of risk and, at the very end of the discussion got to the question that was posed to them, which is that of risk perception of various technical options in the field of radioactive waste management. Some of the points that were made in this discussion is a reality that the group, as decision-makers, have to deal with, and it has to be treated as a reality. Secondly, the scientist looks at risk from the classic definition of ''probability times consequences'', but the public only looks at the consequences side of the equation, and too often the probability of something happening is treated as a probability of one that it will actually happen. A third problem that was identified in this area is that often the efforts to make the disposal of waste safer may contribute, in the public mind, to the fact that the risk is even more hazardous. And the last problem is that people do not trust what a decision maker is saying when he talks about the fact that there is little probability of something happening. The group then went on to a discussion of how he should try to treat risk perception. One point that was made is that voluntary acceptance of a risk is important. A second point that was made on how to deal with risk perception problems is that the group could try to put the risk of radioactive waste disposal in the perspective of other risks to society, from the chemical industry for instance. The group also talked about the possibility of putting the benefits in perspective for people. Another point was that the group should have different communications strategies for different audiences. But, the more the public is involved in the decision making process, the more comfortable they are going to be with the risk, and the more consistent the perception of risk may be with the scientific definition thereof. In terms of new technologies, new innovations on the generation and management of waste, although these may actually

    Understanding the issues surrounding public acceptance of homeland security systems is important for balancing security needs and potential civil liberties infringements. A psychometric survey was used in an exploratory study of attitudes regarding homeland security systems. Psychometric rating data were obtained from 182 respondents on psychological attributes associated with 12 distinct types of homeland security systems. An inverse relationship was observed for the overall rating attributes of acceptability and risk of civil liberties infringement. Principal components analysis (PCA) yielded a two-factor solution with the rating scale loading pattern suggesting factors of perceived effectiveness and perceived intrusiveness. These factors also showed an inverse relationship. The 12 different homeland security systems showed significantly different scores on the rating scales and PCA factors. Of the 12 systems studied, airport screening, canine detectors, and radiation monitoring at borders were found to be the most acceptable, while email monitoring, data mining, and global positioning satellite (GPS) tracking were found to be least acceptable. Students rated several systems as more effective than professionals, but the overall pattern of results for both types of subjects was similar. The data suggest that risk perception research and the psychometric paradigm are useful approaches for quantifying attitudes regarding homeland security systems and policies and can be used to anticipate potentially significant public acceptance issues.

  1. Perception of injury risk among amateur Muay Thai fighters.

    2017-12-01

    Muay Thai is a style of kickboxing that allows full-contact blows to an unprotected head, torso and legs, and, as in any combat sport, there is an inherent risk of injury. Previous observational studies have shown there is a substantial risk of injury in competitive kickboxing. None of these studies, however, have investigated the potential role of psychological risk factors and, consequently, little is known about the perception of injury risk among these athletes. Notwithstanding the important role risk perception may play in the occurrence and prevention of sports injuries, there is very limited empirical data pertaining to athletes in full-contact combat sports such as Muay Thai. Because the development and successful implementation of effective injury prevention policies for combat sports are likely to benefit from an increased understanding of the perception of injury risk and sport safety attitudes and behavior of its participants, further study is warranted. Muay Thai fighters were invited to complete an online survey in which they rated the perceived risk of injury in a range of different sports, including Muay Thai kickboxing. Perceived comparative risk was obtained indirectly by subtracting perceived risk of injury to oneself from perceived risk of injury to a peer. Data were analyzed using descriptive statistics, comparison of means, and ordinal logistic regression. Contrary to the best available epidemiological evidence, Muay Thai fighters perceived the risk of injury in their own sport to be average and significantly lower than that in other collision and contact sports, including popular combat sports such as boxing and mixed martial arts. On average, Muay Thai fighters perceived their own risk injury to be significantly lower compared to their peers (p injury risk perception and actual risk among Muay Thai fighters. Moreover, these athletes also exhibit a slight degree comparative optimism or unrealistic optimism. Because behavior is determined by

    Cardiovascular disease (CVD) has emerged as a major cause of morbidity and mortality in HIV-infected adults. Research in noninfected populations has suggested that knowledge of CVD risk factors significantly influences perceptions of risk. This cross-sectional study describes CVD risk factor knowledge and risk perception in HIV-infected adults. We recruited 130 HIV-infected adults (mean age = 48 years, 62% male, 56% current smokers, mean years since HIV diagnosis, 14.7). The mean CVD risk factor knowledge score was fairly high. However, controlling for age, CVD risk factor knowledge was not predictive of perceived risk [F(1, 117) = 0.13, p > .05]. Estimated risk and perceived risk were weakly but significantly correlated; r (126) = .24, p = .01. HIV-infected adults are at increased risk for CVD. Despite having adequate risk-factor knowledge, CVD risk perception was inaccurate. Improving risk perception and developing CVD risk reduction interventions for this population are imperative.

    The paper defines the Safety Capacity of Chemical Industrial Park (SCCIP) from the perspective of acceptable regional risk. For the purpose of exploring the evaluation model for the SCCIP, a method based on quantitative risk assessment was adopted for evaluating transport risk and to confirm reasonable safety transport capacity of chemical industrial park, and then by combining with the safety storage capacity, a SCCIP evaluation model was put forward. The SCCIP was decided by the smaller one between the largest safety storage capacity and the maximum safety transport capacity, or else, the regional risk of the park will exceed the acceptable level. The developed method was applied to a chemical industrial park in Guangdong province to obtain the maximum safety transport capacity and the SCCIP. The results can be realized in the regional risk control of the park effectively.

In order to evaluate package attributes, in focus groups discussions, 19 consumers chose the most important factors that influence their purchase decisions. Next, 102 consumers evaluated six commercial brands of snack bars in a three-session acceptance test: the first with no information about the product, the second containing the product package and the third with information on health-related claims associated with consumption of the bar. In general, package attributes, price and flavor were the most important factors that influence the purchase of snack bars. Health claims positively influenced consumer acceptance, but information concerning the absence of gluten and lactose did not significantly alter sensory acceptance. The presence of omega-3s, sugars, preservatives, flavorings and colorings have the potential to improve acceptability, because they were able to raise the acceptance of the seed bar, removing it from the rejection region. Protein and nut bars are not well known to the general public and the lower mean acceptance of the seed and protein bars demonstrated the need for sensorial improvement.

    Although risk perception is a key predictor in health behavior theories, current conceptions of risk comprise only one (deliberative) or two (deliberative vs. affective/experiential) dimensions. This research tested a tripartite model that distinguishes among deliberative, affective, and experiential components of risk perception. In two studies, and in relation to three common diseases (cancer, heart disease, diabetes), we used confirmatory factor analyses to examine the factor structure of the tripartite risk perception (TRIRISK) model and compared the fit of the TRIRISK model to dual-factor and single-factor models. In a third study, we assessed concurrent validity by examining the impact of cancer diagnosis on (a) levels of deliberative, affective, and experiential risk perception, and (b) the strength of relations among risk components, and tested predictive validity by assessing relations with behavioral intentions to prevent cancer. The tripartite factor structure was supported, producing better model fit across diseases (studies 1 and 2). Inter-correlations among the components were significantly smaller among participants who had been diagnosed with cancer, suggesting that affected populations make finer-grained distinctions among risk perceptions (study 3). Moreover, all three risk perception components predicted unique variance in intentions to engage in preventive behavior (study 3). The TRIRISK model offers both a novel conceptualization of health-related risk perceptions, and new measures that enhance predictive validity beyond that engendered by unidimensional and bidimensional models. The present findings have implications for the ways in which risk perceptions are targeted in health behavior change interventions, health communications, and decision aids.

    2015-09-01

    Few studies have investigated how gamblers perceive risk or the role of risk perception in disordered gambling. The purpose of the current study therefore was to obtain data on lay gamblers' beliefs on these variables and their effects on decision-making, behaviour, and disordered gambling aetiology. Fifteen regular lay gamblers (non-problem/low risk, moderate risk and problem gamblers) completed a semi-structured interview following mental models and grounded theory methodologies. Gambler interview data was compared to an expert 'map' of risk-perception, to identify comparative gaps or differences associated with harmful or safe gambling. Systematic overlapping processes of data gathering and analysis were used to iteratively extend, saturate, test for exception, and verify concepts and themes emerging from the data. The preliminary findings suggested that gambler accounts supported the presence of expert conceptual constructs, and to some degree the role of risk perception in protecting against or increasing vulnerability to harm and disordered gambling. Gambler accounts of causality, meaning, motivation, and strategy were highly idiosyncratic, and often contained content inconsistent with measures of disordered gambling. Disordered gambling appears heavily influenced by relative underestimation of risk and overvaluation of gambling, based on explicit and implicit analysis, and deliberate, innate, contextual, and learned processing evaluations and biases.

    The people who asked me to give a talk for the Spanish Nuclear Society's 28th Annual Meeting, at the invitation of WIN (Women in Nuclear), have challenged me, or at least that is what my colleagues believe, to tackle the difficult task of venturing into fields unfamiliar to anyone who is not involved in University teaching in communication and journalism. However, the challenge was very appealing to me, first of all because it was an invitation from WIN (Women in Nuclear), which I would like to congratulate, together with the Steering Committee, for having selected Salamanca as the meeting venue in this very important year for this city (it has been selected as European cultural city for 2002, along with the Belgian city of Bruges), If there is any place that has been immersed in scientific culture throughout the centuries it is Salamanca, where every one of its stones could tell us a history of the convergence and divergence between knowledge and society. This Universidad Pontificia of Salamanca also encloses centuries of wisdom within its walls. I have mentioned the first reason for accepting the challenge: the invitation from WIN Espana. The second reason why I accepted is that, some years ago, the world of nuclear energy, them unknown to me, started coming up in conversations with friends, one of whom works in this field. That history of discovery began in a levelly little Swiss town, in Grundenwald, not far from Eintein's Bern, whom I will mention later on

    This paper explores and quantifies the recent Wall Street fears concerning nuclear utilities. An econometric model of investor behavior is presented that quantifies the nuclear risk premium for the period when nuclear fear among investors was at its height, in mid-1984. The principal finding is that the risk premium relates primarily to nuclear construction work in progress (CWIP), rather than to the commercial operation of completed nuclear plants. 7 references, 1 table

    2009-09-01

    We explored the risky driving behaviors and risk perceptions of a cohort of young novice drivers and sought to determine their associations with crash risk. Provisional drivers aged 17 to 24 (n = 20 822) completed a detailed questionnaire that included measures of risk perception and behaviors; 2 years following recruitment, survey data were linked to licensing and police-reported crash data. Poisson regression models that adjusted for multiple confounders were created to explore crash risk. High scores on questionnaire items for risky driving were associated with a 50% increased crash risk (adjusted relative risk = 1.51; 95% confidence interval = 1.25, 1.81). High scores for risk perception (poorer perceptions of safety) were also associated with increased crash risk in univariate and multivariate models; however, significance was not sustained after adjustment for risky driving. The overrepresentation of youths in crashes involving casualties is a significant public health issue. Risky driving behavior is strongly linked to crash risk among young drivers and overrides the importance of risk perceptions. Systemwide intervention, including licensing reform, is warranted.

    risk perception in women with high risk pregnancies affects their decisions about perinatal care and is of interest to anyone involved in the care of pregnant women. This paper provides a metasynthesis of qualitative studies of risk perception in women with high risk pregnancies. a systematic search of eight electronic databases was conducted. Additional papers were obtained through searching references of identified articles. Six studies were identified that reported qualitative research into risk perception in relation to high risk pregnancy. A metasynthesis was developed to describe and interpret the studies. the synthesis resulted in the identification of five themes: determinants of risk perception; not seeing it the way others do; normality versus risk; if the infant is ok, I׳m ok; managing risk. this metasynthesis suggests women at high risk during pregnancy use multiple sources of information to determine their risk status. It shows women are aware of the risks posed by their pregnancies but do not perceive risk in the same way as healthcare professionals. They will take steps to ensure the health of themselves and their infants but these may not include following all medical recommendations. Copyright © 2013 Elsevier Ltd. All rights reserved.

  14. Toward understanding the active SETI debate: Insights from risk communication and perception

    2014-12-01

    Insights from the robust field of risk communication and perception have to date been almost totally absent from the policy debate regarding the relative risks and merits of Active SETI or Messaging to Extraterrestrial Intelligence (METI). For many years, the practice (or proposed practice) of Active SETI has generated a vigorous and sometimes heated policy debate within the scientific community. There have also been some negative reactions in the media toward the activities of those engaged in Active SETI. Risk communication is a scientific approach to communication regarding situations involving potentially sensitive or controversial situations in which there may be high public concern and low public trust. The discipline has found wide acceptance and utility in fields such as public health, industrial regulation and environmental protection. Insights from the scientific field of risk communication (such as omission bias, loss aversion, the availability heuristic, probability neglect, and the general human preference for voluntary over involuntary risks) may help those who have participated in either side of the debate over Active SETI to better understand why the debate has taken on this posture. Principles of risk communication and risk perception may also help those engaged in Active SETI to communicate more effectively with other scientists, the public, with the media, and with policy makers regarding their activities and to better understand and respond to concerns expressed regarding the activity.

  15. Why risk acceptance criteria need to be defined by the authorities and not the industry?

    International Nuclear Information System (INIS)

    Abrahamsen, Eirik Bjorheim; Aven, Terje

    2012-01-01

    In various industries it is common to use risk acceptance criteria to support decision-making. The criteria are seen as absolute in the sense that measures need to be implemented if the criteria are not met. In Norway the petroleum regulations state that the operator has a duty to formulate risk acceptance criteria relating to major accidents and to the environment. This practice is in line with the internal control principle, which states that the operator has the full responsibility for identifying the hazards and seeing that they are controlled. In this paper we discuss the rationale for this practice. The expected utility theory, which is the backbone for all economic thinking, is used as a basis for the discussion. We show that if risk acceptance criteria are to be introduced as a risk management tool, they should be formulated by the authorities, as is the common scheme seen in many countries and industries, for example in the UK. Risk acceptance criteria formulated by the industry would not in general serve the interest of the society as a whole.

    Crisis communication is an indicator of a sustaining public normalcy that serves to control and decrease any untoward situations during disasters' meltdown. Prior findings highlighted that 25.85 percent of arising organizational disputes can be resolved using public announcements and an enhancement of public awareness through avoiding related dissatisfactions, disorders and untoward circumstances during radiation and nuclear emergencies. Hence, in this paper, we are interrogating Malaysians on their perception of risk regarding to radiation and nuclear disasters and emergencies. The principal aim is to identify the relationship between the IAEA's initiated risk perception characteristics and the content of the respective public acceptance reports. Those relationships are described and analyzed into a network diagram using the ATLAS.ti software consisting of Clustering and C-Coefficient analyses. This diagram identifies the main variables relating to significant characteristics of risk perception. Future studies should further evaluate the intensity of public opinion against the suggested constructs of executing a thorough and structured risk management mechanism, to advance public trust as well as crisis communication.

    Currently, more conflicts appear between the public and government over the establishment of the 4th nuclear power plant in Taiwan. In order to improve risk management by the Society, understanding the risk perception of the public will be essential. A pilot study on the risk perception toward nuclear power operation and other current risks was conducted in summer of 1999. In addition to perception towards nuclear power operation, the survey evaluated several dimensions of health-related risks including smoking, chemical wastes, nuclear wastes, air transportation, AIDS, and food intoxication. The questionnaire was designed to be proceeded under systemic instruction and followed with self-filling. 57 (85.1%) of 67 respondents worked at the Taipei Metropolitan Rapid Transportation, including 62 male subjects (92.5%). 44 (69.8%) respondents favored building the 4th nuclear power plant in Taiwan. The acceptable distance between their houses and the nuclear power plant was 145.13 km in average, as compared with 400 km that of North and South of Taiwan. The mean expenses they are willing to pay to reduce the risk of the NPP is about US $7.73, 0.56% of their average income. However, the levels of risks toward nuclear power operation is significant higher than these for air transportation, smoking, and food intoxication. Government's spending is assumed more effective to reduce the threats from risks of nuclear power operation, rather than professional's or experts' effects. Besides, other related factors include levels of involuntary exposure to NP operation (p<0.001) and number of people potentially in danger (p<0.001). These 2 altitudes are positively correlated with the respondents' perceived risks. Different attitudes toward NP operation within these engineers, and those evaluated by others, are of great interest. Further evaluation will be conducted to compare the mechanism involved.

    Slovic, P; MacGregor, D; Kraus, N N

    1987-10-01

    Descriptions of safety engineering defects of the kind that compel automobile manufacturers to initiate a recall campaign were evaluated by individuals on a set of risk characteristic scales that included overall vehicle riskiness, manufacturer's ability to anticipate the defect, importance for vehicle operation, severity of consequences and likelihood of compliance with a recall notice. A factor analysis of the risk characteristics indicated that judgments could be summarized in terms of two composite scales, one representing the uncontrollability of the damage the safety defect might cause and the other representing the foreseeability of the defect by the manufacturer. Motor vehicle defects were found to be highly diverse in terms of the perceived qualities of their risks. Location of individual defects within the factor space was closely associated with perceived riskiness, perceived likelihood of purchasing another car from the same manufacturer, perceived likelihood of compliance with a recall notice, and actual compliance rates.

    2009-08-01

    Full Text Available Abstract Background Counselees are more aware of genetics and seek information, reassurance, screening and genetic testing. Risk counseling is a key component of genetic counseling process helping patients to achieve a realistic view for their own personal risk and therefore adapt to the medical, psychological and familial implications of disease and to encourage the patient to make informed choices 12. The aim of this study was to conceptualize risk perception and anxiety about cancer in individuals attending to genetic counseling. Methods The questionnaire study measured risk perception and anxiety about cancer at three time points: before and one week after initial genetic counseling and one year after completed genetic investigations. Eligibility criteria were designed to include only index patients without a previous genetic consultation in the family. A total of 215 individuals were included. Data was collected during three years period. Results Before genetic counseling all of the unaffected participants subjectively estimated their risk as higher than their objective risk. Participants with a similar risk as the population overestimated their risk most. All risk groups estimated the risk for children's/siblings to be lower than their own. The benefits of preventive surveillance program were well understood among unaffected participants. The difference in subjective risk perception before and directly after genetic counseling was statistically significantly lower in all risk groups. Difference in risk perception for children as well as for population was also statistically significant. Experienced anxiety about developing cancer in the unaffected subjects was lower after genetic counseling compared to baseline in all groups. Anxiety about cancer had clear correlation to perceived risk of cancer before and one year after genetic investigations. The affected participants overestimated their children's risk as well as risk for anyone in

Two of these, viz. health and process-related quality, are credence dimensions, ie, a matter of consumer trust...

  16. Do we see how they perceive risk? An integrated analysis of risk perception and its effect on workplace safety behavior.

    Xia, Nini; Wang, Xueqing; Griffin, Mark A; Wu, Chunlin; Liu, Bingsheng

    2017-09-01

    While risk perception is a key factor influencing safety behavior, the academia lacks specific attention to the ways that workers perceive risk, and thus little is known about the mechanisms through which different risk perceptions influence safety behavior. Most previous research in the workplace safety domain argues that people tend to perceive risk based on rational formulations of risk criticality. However, individuals' emotions can be also useful in understanding their perceptions. Therefore, this research employs an integrated analysis concerning the rational and emotional perspectives. Specifically, it was expected that the identified three rational ways of perceiving risk, i.e., perceived probability, severity, and negative utility, would influence the direct emotional risk perception. Furthermore, these four risk perceptions were all expected to positively but differently influence safety behavior. The hypotheses were tested using a sample of 120 construction workers. It was found that all the three rational risk perceptions significantly influenced workers' direct perception of risk that is mainly based on emotions. Furthermore, safety behavior among workers relied mainly on emotional perception but not rational calculations of risk. This research contributes to workplace safety research by highlighting the importance of integrating the emotional assessment of risk, especially when workers' risk perception and behavior are concerned. Suggested avenues for improving safety behavior through improvement in risk perception include being aware of the possibility of different ways of perceiving risk, promoting experience sharing and accident simulation, and uncovering risk information.

    This study investigated the influence of personality characteristics and gender on adolescents' perception of risk and their risk-taking behaviour. Male and female participants (157 females: 116 males, aged 13-20) completed self-report measures on risk perception, risk-taking and personality. Male participants perceived behaviours as less risky, reportedly took more risks, were less sensitive to negative outcomes and less socially anxious than female participants. Path analysis identified a model in which age, behavioural inhibition and impulsiveness directly influenced risk perception, while age, social anxiety, impulsiveness, sensitivity to reward, behavioural inhibition and risk perception itself were directly or indirectly associated with risk-taking behaviour. Age and behavioural inhibition had direct relationships with social anxiety, and reward sensitivity was associated with impulsiveness. The model was representative for the whole sample and male and female groups separately. The observed relationship between age and social anxiety and the influence this may have on risk-taking behaviour could be key for reducing adolescent risk-taking behaviour. Even though adolescents may understand the riskiness of their behaviour and estimate their vulnerability to risk at a similar level to adults, factors such as anxiety regarding social situations, sensitivity to reward and impulsiveness may exert their influence and make these individuals prone to taking risks. If these associations are proven causal, these factors are, and will continue to be, important targets in prevention and intervention efforts.

    Transgender women experience a variety of factors that may contribute to HIV risk. The purpose of this study was to explore links among HIV risk perception, knowledge, and sexual risk behaviors of transgender women. A descriptive, correlational study design was used. Fifty transgender women from the South Florida area were enrolled in the study. Transgender women completed a demographic questionnaire and standardized instruments measuring HIV risk perception, knowledge, and sexual risk behaviors. Transgender women reported low levels of HIV risk perception, and had knowledge deficits regarding HIV risk/transmission. Some participants engaged in high-risk sexual behaviors. Predictors of sexual risk behaviors among transgender women were identified. More research is needed with a larger sample size to continue studying factors that contribute to sexual risk behaviors in the understudied population of transgender women. Evidence-based guidelines are available to assist public health nurses in providing care for transgender women. Nurses must assess HIV perception risk and HIV knowledge and provide relevant education to transgender women on ways to minimize sexual risk. © 2016 Wiley Periodicals, Inc.

  20. Operational implications of accepting and denying whether a true value of risk exists

    DEFF Research Database (Denmark)

    Kozin, Igor

    It is suggested to look on probabilistic risk quantities and concepts through the prism of accepting one of the views: whether a true value of risk exists or not. It will be argued that discussions until now have been primarily focused on closely related topics that are different from the suggested...... one. In general, the values of risks are not known precisely and the analyst has the option to consider that convergence to a precise value of risk is possible in the limit. That is, the true value exists but due to limited time, resources or other limitations in assessing probabilities...

    Political ethics is a concept that is increasingly emerging in current public debate about the risks of technolgy. A risk that cannot be limited in time or in space, the risk we have got used to call the 'risk to be reasonably accepted', seems unacceptable. Energy generation and supply may not be given higher priority than life and health. It would be high time to prove courage and efficiency by opposing the 'nuclear laws of inertia', stopping nuclear technoloy, and admitting one's own feeling of insecurity. (DG) [de

    Full Text Available Abstract Consumer behaviors are more important in the study of Green Marketing. This studied aims to examined buying behavior of consumers on organic products which is formed by perception of quality and perception of risk. The research model with three hypotheses to explained the relationship and influenced between the constructs that perception of quality perception of risk and purchase decision. In these empirical studied treated 366 respondents from customer of retail supermarkets in West Java - Indonesia. Results of research founded a significant negative relationship between perception of quality and perception of risk. As well as the behavior of perception of quality and the perception of risk has a significant influenced on purchase decision. Retail self-service needs to improve the perception of quality and reduces the risk perception of the consumers if purchasing behavior of consumers want increase on organic products. This studied was useful in raising awareness of self-service retail and consumers for environmentally friendly products.

    The aim of the study was to determine temporal orientation in patients diagnosed with RR-MS as compared with that of healthy individuals; to analyse self-evaluated acceptance levels in terms of physical and psychological condition and self-reliance; an attempt to identify factors of illness acceptance in patients with RR-MS including temporal perspective. Acceptance of Illness Scale (AIS, adapted into Polish by Z. Juczyński), Zimbardo Time Perspective Inventory (ZTPI, adapted into Polish by M. Mażewski), and original interview aimed to assess socio-demographic data and self-evaluated physical as well as psychological condition and self-reliance of patients with MS (referred to the neurological testing according to the EDSS). Patients with RR-MS focus on fatalistic and hedonistic present more than healthy individuals. They also tend to reflect on their negative past experience. Acceptance of illness correlated positively with subjective assessment of physical and psychological condition as well as self-reliance, and negatively with objective disability score (measured with the use of EDSS) and a factor considering time of disease duration. Avoiding contemplation of negative past and concentrating on hedonistic future constitute significant predictors of illness acceptance. These results may be of importance in terms of holistic approach to treatment of RR-MS patients. In the initial stage of the disease progression, patients might benefit from psychological support due to change in temporal orientation.

  8. Waste-acceptance criteria and risk-based thinking for radioactive-waste classification

    International Nuclear Information System (INIS)

    Lowenthal, M.D.

    1998-01-01

    The US system of radioactive-waste classification and its development provide a reference point for the discussion of risk-based thinking in waste classification. The official US system is described and waste-acceptance criteria for disposal sites are introduced because they constitute a form of de facto waste classification. Risk-based classification is explored and it is found that a truly risk-based system is context-dependent: risk depends not only on the waste-management activity but, for some activities such as disposal, it depends on the specific physical context. Some of the elements of the official US system incorporate risk-based thinking, but like many proposed alternative schemes, the physical context of disposal is ignored. The waste-acceptance criteria for disposal sites do account for this context dependence and could be used as a risk-based classification scheme for disposal. While different classes would be necessary for different management activities, the waste-acceptance criteria would obviate the need for the current system and could better match wastes to disposal environments saving money or improving safety or both

    to explore perceptions and examples of risk related to pregnancy and childbirth in rural and remote Australia and how these influence the planning of maternity services. data collection in this qualitative component of a mixed methods study included 88 semi-structured individual and group interviews (n=102), three focus groups (n=22) and one group information session (n=17). Researchers identified two categories of risk for exploration: health services risk (including clinical and corporate risks) and social risk (including cultural, emotional and financial risks). Data were aggregated and thematically analysed to identify perceptions and examples of risk related to each category. fieldwork was conducted in four jurisdictions at nine sites in rural (n=3) and remote (n=6) Australia. 117 health service employees and 24 consumers. examples and perceptions relating to each category of risk were identified from the data. Most medical practitioners and health service managers perceived clinical risks related to rural birthing services without access to caesarean section. Consumer participants were more likely to emphasise social risks arising from a lack of local birthing services. our analysis demonstrated that the closure of services adds social risk, which exacerbates clinical risk. Analysis also highlighted that perceptions of clinical risk are privileged over social risk in decisions about rural and remote maternity service planning. a comprehensive analysis of risk that identifies how social and other forms of risk contribute to adverse clinical outcomes would benefit rural and remote people and their health services. Formal risk analyses should consider the risks associated with failure to provide birthing services in rural and remote communities as well as the risks of maintaining services.

  13. Risk and benefit perceptions of mobile phone and base station technology in Bangladesh.

    Research in developed countries showed that many citizens perceive that radio signals transmitted by mobile phones and base stations represent potential health risks. Less research has been conducted in developing countries focused on citizen perceptions of risks and benefits, despite the recent and rapid introduction of mobile communication technologies. This study aims to identify factors that are influential in determining the tradeoffs that Bangladeshi citizens make between risks and benefits in terms of mobile phone technology acceptance and health concerns associated with the technology. Bangladesh was selected as representative of many developing countries inasmuch as terrestrial telephone infrastructure is insubstantial, and mobile phone use has expanded rapidly over the last decade, even among the poor. Issues of importance were identified in a small-scale qualitative study among Bangladeshi citizens (n = 13), followed by a survey within a sample of Bangladeshi citizens (n = 500). The results demonstrate that, in general, the perceived benefits of mobile phone technology outweigh the risks. The perceived benefits are primarily related to the social and personal advantages of mobile phone use, including the ability to receive emergency news about floods, cyclones, and other natural disasters. Base stations were seen as a symbol of societal advance. The results furthermore suggest that overall risk perceptions are relatively low, in particular health risks, and are primarily driven by perceptions that related to crime and social inconvenience. Perceived health risks are relatively small. These findings show that risk communication and management may be particularly effective when contextual factors of the society where the system is implemented are taken into consideration.

    This report was prepared by ERC Environmental and Energy Services Co. (ERCE) on behalf of the Pacific Northwest Laboratory (PNL) and the US Department of Energy (DOE) between February and August 1989. It updates previous reports prepared by ERCE on public acceptance of waste management activities in foreign countries. The report is intended to serve as an aid in understanding experiences with public acceptance of waste activities in foreign countries, and thereby benefit US efforts with respect to public acceptance based on lessons learned abroad. Seven countries are addressed in the report: Belgium, the Federal Republic of Germany, France, Japan, Sweden, Switzerland, and the United Kingdom. The information provided in this report was obtained both from direct interviews of the responsible waste management officials in the seven countries surveyed and from source documents provided by these individuals

  15. The precautionary principle and/or risk assessment in World Trade Organization decisions: a possible role for risk perception.

    Goldstein, Bernard; Carruth, Russellyn S

    2004-04-01

    Risk analysis has been recognized and validated in World Trade Organization (WTO) decision processes. In recent years the precautionary principle has been proposed as an additional or alternative approach to standard risk assessment. The precautionary principle has also been advocated by some who see it as part of postmodern democracy in which more power is given to the public on health and safety matters relative to the judgments of technocrats. A more cynical view is that the precautionary principle is particularly championed by the European Community as a means to erect trade barriers. The WTO ruling against the European Community's trade barrier against beef from hormone-treated cattle seemed to support the use of risk assessment and appeared to reject the argument that the precautionary principle was a legitimate basis for trade barriers. However, a more recent WTO decision on asbestos contains language suggesting that the precautionary principle, in the form of taking into account public perception, may be acceptable as a basis for a trade barrier. This decision, if followed in future WTO trade disputes, such as for genetically modified foods, raises many issues central to the field of risk analysis. It is too early to tell whether the precautionary principle will become accepted in WTO decisions, either as a supplement or a substitute for standard risk assessment. But it would undermine the value of the precautionary principle if this principle were misused to justify unwarranted trade barriers.

  17. Technological stigmatism, risk perception, and truth

    1998-01-01

    Technological stigmas can be a source of confusion and misunderstandings of the effect on public health and safety of technological activities. The result can be a gross waste of national resources to fix the 'stigma' rather than the real problem. Fueling technological stigmas has become a visible activity, especially among non-technical professionals. Further, it is not clear that these same critics are accountable for their influence on policy and practices that may adversely affect people's lives and financial resources. Their bad news of alleged high risk and incompetent technologists is more appealing to the press than the more technical and apparently boring news of finding engineering solutions to real problems. The issue of technological stigma is especially visible in relation to the environmental and safety effects of the nuclear and chemical industries. These industries are in an extremely defensive position because the stigmatizes put much more emphasis on their risks than on their benefits to society. There is the genuine threat of the denial of important technologies in the nuclear and chemical fields and a resulting loss of lives and resources. The actions required to better tell the whole cost-risk-benefit story of specific technologies have to come from all of the groups involved. The critics and stigmatizers need to be more accountable for their assertions, the technologists need to involve the public more in their consideration of technological solutions to environmental and safety issues, and the press needs to present all of the facts rather than just the sensational or 'outrage' part of the story.

    2012-07-01

    Using the Annenberg Perception of Tobacco Risk Survey 2, this paper finds that perceived risk deters smoking among persons aged 14-22 years who think that it is relatively difficult to quit smoking and that onset of deleterious health effects occurs relatively quickly. Perceived health risk, however, does not affect the smoking status of young people who hold the opposite beliefs. These results are consistent with predictions of rational addiction models and suggest that young people, who view smoking as more addictive and health effects as more immediate, may have greater incentive to consider long-term health effects in their decision to smoke.

    Some of the key findings are discussed of psychological research on the perception of risks and attitudes with respect to the use of uranium and coal for electricity generation. It appears that attitudes are mostly not based on ideology but rather determined by a trade-off of expected risks and advantages. Lay estimates of probabilities are compared with expert judgements. In the last section attitudes of people living near existing or planned power plants are analyzed. Serious doubts are raised about the possibilities to give residents economic compensation for exposure to risks. 1 fig., 29 refs.

    Background Patients at higher than average risk of heritable cancer may process risk information differently than the general population. However, little is known about clinical, demographic, or psychosocial predictors that may impact risk perception in these groups. The objective of this study was to characterize factors associated with perceived risk of developing cancer in groups at high risk for cancer based on genetics or family history. Methods We searched Ovid MEDLINE, Ovid Embase, Ovid PsycInfo, and Scopus from inception through April 2009 for English-language, original investigations in humans using core concepts of "risk" and "cancer." We abstracted key information and then further restricted articles dealing with perceived risk of developing cancer due to inherited risk. Results Of 1028 titles identified, 53 articles met our criteria. Most (92%) used an observational design and focused on women (70%) with a family history of or contemplating genetic testing for breast cancer. Of the 53 studies, 36 focused on patients who had not had genetic testing for cancer risk, 17 included studies of patients who had undergone genetic testing for cancer risk. Family history of cancer, previous prophylactic tests and treatments, and younger age were associated with cancer risk perception. In addition, beliefs about the preventability and severity of cancer, personality factors such as "monitoring" personality, the ability to process numerical information, as well as distress/worry also were associated with cancer risk perception. Few studies addressed non-breast cancer or risk perception in specific demographic groups (e.g. elderly or minority groups) and few employed theory-driven analytic strategies to decipher interrelationships of factors. Conclusions Several factors influence cancer risk perception in patients at elevated risk for cancer. The science of characterizing and improving risk perception in cancer for high risk groups, although evolving, is still

  7. Some approaches to understanding public perceptions of risk

    International Nuclear Information System (INIS)

    Greer-Wootten, B.

    1981-01-01

    The debate on nuclear power contains a central set of arguments that can be related, by and large, to differences in the meaning of risk assessment for various concerned publics. At an earlier point in time the arguments largely concerned power production (reactor safety), but now most components of the nuclear fuel cycle are subject to risk perceptions. The strongest levels of public concern over time have focussed on waste management, and in this area illustrates most clearly the gaps between the assessments of the technical community and those of the publics. In order to understand such gaps, a theoretical framework is necessary. The broadest scope for such a framework is found in the I.I.A.S.A. - I.A.E.A. model developed by H.J. Otway, with its three interrelated components of risk estimation (technical), risk evaluation (public) and risk management. The model is described in this paper, as well as a number of empirical studies that derive from it and attempt to measure public perceptions of risks. These studies are then compared to several alternative explanations: the use of public opinion surveys; risk rating tasks based on psychologicl theory; the structure of arguments used by members of the public in qualitative focus group discussions; and a model of local community conflict derived from the content analysis of newspapers. Throughout the discussion, examples are taken wherever possible, from recent Canadian studies, in which the effects of major incidents (such as T.M.I., the Mississauga derailment, the Blind River refinery siting controversy, etc.) become apparent. It is suggested that our understanding of public perceptions of risks cannot be divorced from the set of broad societal concerns evidenced in the I.I.A.S.A. - I.A.E.A. model, and that the crucial elements of this approach are seen in its emphasis on the decision-making process

    The Industry Degraded Core (IDCOR) Program was designed to develop a comprehensive, technically sound position on the issues related to potential accidents in light water reactors. One of the goals is to acquire knowledge and data so that a more realistic approach to the problem is possible. Some of the IDCOR tasks develop information in a Probabilistic Risk Assessment (PRA) framework. The PRA approach is structured upon reliability characteristics for individual components, such as pumps, valves and relays, which can be used to predict the frequency of system failures. System failure combinations can then be used to predict the probability of undesirable plant response to given initiating events. The IDCOR PRA tasks provide a significant amount of information related to the response of the plant to severe accidents. This information has been derived in a logical and consistent manner and so provides a coherent and rational basis for decision-making

    Public opposition to genetically modified (GM) food and crops is widely interpreted as the result of the public's misperception of the risks. With scientific assessment pointing to no unique risks from GM crops and foods, a strategy of accurate risk communication from trusted sources has been advocated. This is based on the assumption that the benefits of GM crops and foods are self-evident. Informed by the interpretation of some qualitative interviews with lay people, we use data from the Eurobarometer survey on biotechnology to explore the hypothesis that it is not so much the perception of risks as the absence of benefits that is the basis of the widespread rejection of GM foods and crops by the European public. Some respondents perceive both risks and benefits, and may be trading off these attributes along the lines of a rational choice model. However, for others, one attribute-benefit-appears to dominate their judgments: the lexicographic heuristic. For these respondents, their perception of risk is of limited importance in the formation of attitudes toward GM food and crops. The implication is that the absence of perceived benefits from GM foods and crops calls into question the relevance of risk communication strategies for bringing about change in public opinion.

    This study investigated risk perception, well-being, and organizational commitment among nuclear power plant personnel. The study group, 428 employees from a nuclear power plant, completed a questionnaire which included the same questions as those in previous surveys on risk perception of lay persons and industrial workers. Hazards at work were not seen as a sizable problem by nuclear power plant personnel. The study group estimated the safety of nuclear power plants better and the possibility of a serious nuclear accident as more unlikely than the general public. Compared to employees in other industrial companies, the overall perceived risks at work among plant personnel did not exceed the respective perceptions of the reference groups. Risk-related attitudes did not explain well-being among plant personnel, but the relationship between the perceived probability of a serious nuclear accident at work and organizational commitment yielded to a significant correlation: Those plant workers who estimated the likelihood of an accident higher were less committed to the organization. 21 refs., 2 tabs
