Study on public acceptance of nuclear power plants: Evidence from China

Abstract

This empirical study evaluated the public acceptance of nuclear-power plants in China. A conceptual framework was proposed to explain the factors affecting nuclear-power acceptance based on antecedent variables, including social-media-use frequency, social-media information trust, nuclear-power knowledge, nuclear-accident knowledge, and risk-and-benefit perception. An empirical study was operated based on the Haiyang nuclear-power plant by conducting a face-to-face survey among residents who use social-media platforms near the plant. The frequency of social-media-use and the trust on social-media information promote individuals’ knowledge about nuclear power and nuclear accidents, leading to risk and benefit perception. Finally, benefit perception results in nuclear-power acceptance among the individuals. Implications and suggestions for future research are discussed.     

Factors that Determine Human Acceptance of Black Bears

After being extirpated from their historical distribution, black bears (Ursus americanus) have recolonized eastern Oklahoma, USA. As bears continue to establish populations in the region, understanding the cognitive factors that influence human acceptance of black bears will play an important role in facilitating coexistence. We hypothesized that a variety of variables drawing from the cognitive hierarchy and risk perception frameworks would affect human acceptance of black bears in eastern Oklahoma. We collected data using a mail-back questionnaire administered to residents of eastern Oklahoma between August and November 2018. Perceptions of the current black bear population size, attitudes toward bears, valuing Oklahoma wildlife, behavioral intentions, and level of formal education all positively influenced acceptance of bears. Risk-averse respondents and women were less accepting. Outreach to women and encouraging residents to reduce conflict by adopting bear-safe behaviors may help raise acceptance capacity for black bears. © 2021 The Wildlife Society.     

Analysis of Determining Factors of the Public's Risk Acceptance Level in China

This work will characterize risk acceptance in China, based on the psychometric paradigm, and explore the determining factors that influence the risk acceptable level to the Chinese public. For this purpose, a survey was conducted including 12 hazards, 10 risk attributes (including risk acceptance), and demographic variables. First, the research attempted to explore Nanjing citizens’ average risk acceptable level for 12 hazards in China. Second, intercorrelation analysis and factor analysis of nine risk attributes were performed to obtain the suitable risk perception factors as independent variables. Three risk perception models of acceptance were constructed, which were named “Environmental risk model,” “Daily risk model,” and “Technical risk model,” that explained 59.0–69.6% of variance separately. In general, the variables of Knowledge, Benefit, and Trust were found to be significant in all models, implying that these variables are the main determining factors. However, in the environmental risk model, the variable of effect was also significant, which means the determining factors would change for different types of hazards. These results could help the Chinese government to improve the communication of risks with the public and make effective mitigation policies to improve people's rational judgment on the acceptability of risks.     

Learning to live with black bears: A psychological model of acceptance

The reappearance and recovery of large carnivores in human-dominated landscapes creates a need to understand how people will respond to the presence of these animals. We tested a psychological model of acceptance to determine what variables most influence people's acceptance for black bears (Ursus americanus) in an area with an emerging black bear population (Ohio, USA). We hypothesized that people's perceptions of risk and benefit related to bears would mediate the effect of trust (in wildlife management agencies) and personal control (over interactions with and management of wildlife) on acceptance for black bears. We used a mail-back survey of Ohio residents (n = 9,400; adjusted response rate = 35%) to assess the variables of interest and test the hypothesized model. Based on multiple criteria of model fit, the hypothesized model fit the data acceptably well. The model explained approximately 62% of the variance in acceptance, and perception of risk associated with black bears had the largest impact on the level of acceptance. As large carnivore populations expand and interactions with humans increase, our results will aid managers in designing outreach materials and communications aimed at promoting acceptance for large carnivores. Our model suggests that interventions raising an individual's social trust in the managing agency, or personal control can indirectly raise stakeholders' acceptance by reducing risk perception and increasing perception of benefit from carnivores. © 2012 The Wildlife Society.     

Risk Literacy and Risk Perception Among Undergraduates in Mainland China: The Case of BSE

Risk response and cognitive characteristics of different groups are important aspects in risk research. In this article we discuss the general features of risk literacy and perception among undergraduates at Nanjing University and Huaiyin Institute of Technology in China in the case of bovine spongiform encephalopathy (BSE). The results show that: (1) there seem to be no relationships between respondents’ knowledge about BSE and their risk identification; (2) between all contrast samples, the greatest divergence appears in the judgment about probability of risk while the smallest one is the trust in science and technology to avoid BSE; (3) the judgment of hazard probability would be related to gender, family location, and the backgrounds of college and academic specialty. And only gender has impact on the affirmation of hazard with a significant level of 0.05. These findings provide insights into the comprehension of undergraduates’ risk literacy and perception, and can contribute to the improvement of risk communication and management in China.     

Risk Acceptance in Multiple Sclerosis Patients on Natalizumab Treatment

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.

The Representation of Risk in Routine Medical Experience: What Actions for Contemporary Health Policy?

Background

The comprehension of appropriate information about illnesses and treatments, can have beneficial effects on patients’ satisfaction and on important health outcomes. However, it is questionable whether people are able to understand risk properly.

Aim

To describe patients’ representation of risk in common medical experiences by linking such a representation to the concept of trust. A further goal was to test whether the representation of risk in the medical domain is associated to the level of expertise. The third goal was to verify whether socio-demographic differences influence the representation of risk.

Methods

Eighty voluntary participants from 6 health-centers in northern Italy were enrolled to conduct a semi-structured interview which included demographic questions, term-associations about risk representation, closed and open questions about attitudes and perception of risk in the medical context, as well as about medical expertise and trust.

Results

The results showed that people do not have in mind a scientific definition of risk in medicine. Risk is seen as a synonym for surgery and disease and it is often confused with fear. However, general knowledge of medical matters helps people to have a better health management through risk identification and risk information, adoption of careful behaviors and tendency to have a critical view about safety and medical news. Finally, trust proved to be an important variable in risk representation and risk and trust were correlated positively.

Conclusions

People must receive appropriate information about the risks and benefits of treatment, in a form that they can understand and apply to their own circumstances. Moreover, contemporary health policy should empower patients to adopt an active self-care attitude. Methodologies to enhance people’s decision-making outcomes based on better risk communication should be improved in order to enable low literacy population as well elderly people to better understand their treatment and associated risk.     

The Role of Convictions and Trust for Public Protest Potential in the Case of Carbon Dioxide Capture and Storage (CCS)

For the public to accept new technologies, trust and convictions play an important role. In the present research, we used structural equation modeling to examine an extensive causal model of the role of convictions and trust for the public's protest potential against carbon dioxide capture and storage (CCS) among a large sample of the general population (N = 769). Trust, convictions, perceived benefits, and risks were included in the model. Our model fitted the data well. Convictions regarding emission reduction, decentralization of energy production, and tampering with natural structures in the deep subsurface influenced the perception of benefits and risks. Trust, in contrast, was barely influential. Perceived benefits were more prominent for public protest potential than perceived risks. However, perceived benefits did not dominate perceived risks as much as earlier studies found for acceptance. We argue that trust can become fully effective as a determinant of perceived risks and benefits only when the public perceives the distinct positioning of the stakeholders involved. Until then, laypeople are likely to draw on their own convictions and intuitive mental concepts for making decisions about accepting a new technology or protesting it.     

Effects of alternative styles of risk information on EMF risk perception

Risk scenarios characterized by exposures to new technologies with unknown health effects, together with limited appreciation of benefits pose a challenge to risk communication. The present report illustrates this situation through a study of the perceived risk from mobile phones and mobile masts in residential areas. Good information should objectively convey the current state of knowledge. The research question is then how to inform lay people so that they trust and understand the information. We used an Internet‐based survey with 1687 Danish participants randomized to three types of information about radiation from mobile phones and masts. The objective was to study whether different types of information were rated as equally useful, informative, comprehensible, and trustworthy. Moreover, an important issue was whether information would influence risk perception and intended behavior. The conclusion is that lay people rate information about risks associated with a new and largely unknown technology more useful and trustworthy when provided with brief statements about how to handle the risk, rather than more lengthy technical information about why the technology may or may not entail health hazards. Further, the results demonstrate that information may increase concern among a large proportion of the population, and that discrepancies exist between expressed concern and intended behavior.

Effects of Impact Perception on Acceptance Capacity for White-Tailed Deer

ABSTRACT Wildlife professionals require conceptually sound methods to integrate biological and social insights for management of wildlife. The concept of acceptance capacity has been suggested to stimulate integration, although methods to link measures of acceptance capacity with measures of wildlife populations are not fully developed. To clarify relationships between acceptance capacity, wildlife populations, and human values, we explored effects of stakeholder characteristics and impact perception (the recognized, important effects arising from interactions with wildlife) on acceptance capacity. We used a mail-back questionnaire (n = 2,190 responses) to rural residents of southern Michigan 1) to examine whether 3 commonly identified stakeholder groups (hunters, farmers, and nonhunting, nonfarming rural residents) that share a common landscape also perceive similar suites of impacts and hold comparable acceptance capacities for white-tailed deer, and 2) to develop an explanatory model of acceptance capacity for deer. Comparisons among stakeholder groups revealed differences in perception of impacts resulting from interactions with deer; however, participation in hunting and farming were poor predictors of acceptance capacity for deer. Model selection criteria indicate that total effect of impacts perceived explains a majority of variation in acceptance capacity. We conclude that impact perception is a meaningful concept for integration of human values into management of wildlife populations because impacts relate to effects of current wildlife populations and can lead to management actions that address needs and interests of multiple stakeholder groups in changing landscapes.     

The risky business of water resources management: assessment of the public’s risk perception of Oregon’s water resources

Abstract

The premise of this study was to assess the Oregon public’s risk perception concerning Oregon’s water resources. The state has a long-held reputation of having an overabundance of water; however, water shortages, droughts, and impaired water bodies throughout reveal this is not an accurate perception. Climate change models and population growth are projected to exacerbate Oregon’s water situation. A 2010 survey questionnaire was distributed to 1,563 randomly selected Oregon households to elicit the risk perception of ten water-related activities. With a response rate of 51%, the study found the public perceived agricultural and forestry practices as the two greatest risks and private wells as the lowest risk activity. A Risk Perception index found on average the public view the state’s water resources at a moderate risk. These findings can assist water resource managers throughout the Western United States as they develop and implement management strategies in response to climate change.     

Stakeholders’ attitudes to outdoor residual spraying technique for dengue control in Malaysia: A PLS-SEM approach

Outdoor Residual Spraying (ORS) technique is a complementary preventive measure for dengue. The alarming number of dengue cases in Malaysia requires an alternative method to control dengue besides the traditional method such as fogging. However, the introduction of new technologies depends on social acceptance. Therefore, this study was important to determine the factors that influence stakeholders’ attitudes towards the ORS and the moderating factor. A validated instrument was used to randomly interview 399 respondents representing two stakeholder groups which consist of scientists, and the public in Klang Valley, Malaysia. The findings revealed that the stakeholders claimed to have a high degree of religiosity, a high level of trust in the key players, perceived ORS as having high benefits, and displayed highly positive attitudes towards the ORS. The attitudes model towards the ORS model was developed using the SmartPLS software version. The perceived benefit was endorsed as the most important direct predictor of attitudes towards the ORS (ß = 0.618, P<0.001), followed by trust in the key players (ß = 0.151, P<0.001). It is also interesting to note that religiosity served as a moderator for the association between perceived benefit (ß = 0.075, P = 0.024) and perceived risk (ß = 0.114, P = 0.006) with attitudes towards the ORS. The identified predictor factors of stakeholders’ attitudes toward the ORS and the moderating factor can serve as indicators for social acceptance of ORS in developing countries. These indicators can help the policymakers in decision making to implement this technique.     

Public perceptions of climate change adaptation in Singapore dealing with forecasted sea level rise

Abstract

Perceptions of the populace play a central and decisive role in advancing pro-environmental policies. To study attitudes and perceptions towards environmental measures, we apply several items of New Ecological Paradigm (NEP) and Value-Belief-Norm (VBN) theories to cross-examine the public perceptions of climate change in the urban city-state of Singapore through analysis of quantitative questionnaires and qualitative semi-structured interviews. The perceptions were explored about ecological orientation (two dimensions of NEP: level of concern, self-reported knowledge) and environmental behavior (two dimensions of VBN: acceptance and support of national adaptation measures, confidence in adaptation). There is a moderate to high concern for climate change, in general, and sea level rise and flooding, in particular, and the concern is expected to increase in the future. Individuals who indicated a higher level of concern are likely to be more accepting and supportive of climate change measures. Also, while the majority of the populace are amenable to legislative measures from the government, such as enacting pro-environmental laws and more are agreeable to accepting cuts on living standards, as opposed to paying more in prices and taxes. Ecological orientation does not translate directly into environmental behavior, highlighting the gulf between perception and behavior in Singapore.     

An application of the risk perception attitude framework in food safety behavior

An important part of consumers' ability to choose and consume safe food is their level of trust in the information and labeling provided by governments or companies. This study classifies consumers into four groups with similar characteristics regarding food safety issues, using data from the 2016 “Research on Food Consumption Behavior” compiled by the Korea Rural Economic Institute. Using risk perception and efficacy beliefs for food safety, four consumer-type groups were identified: indifference, proactive, avoidance, and responsive. Consumers were classified by applying the risk perception attitude framework, and then the factors that influence the consumer-type classifications were examined. The indifference group accounted for 33.9% of all consumers, the highest percentage, and factors that influenced the classification of consumer types were gender, education level, monthly household income, interest in health, and involvement with food safety. The differences in food safety behaviors proxied by intention to pay higher prices for safe food and checking food labels were identified by consumer type, and these differences were statistically significant.     

Low Risks,High Public Concern? The Cases of Persistent Organic Pollutants (POPs), Heavy Metals,and Nanotech Particles

Risk is an ancient, historic concept; almost everybody has some subjective understanding of what is meant by it. However, there are different types of knowledge, notions, interests, and processes involved both in science-based risk assessment and subjective risk perception. In the present article, we show how risk assessment and risk perception are intricately intertwined. This is exemplified by introducing the state-of-the-art risk assessments applied to three cases (i.e., heavy metals, POPs, and nanotech particles), each with their own unique history and degree of scientific understanding. We elaborate that, when dealing with risk, actors employ different notions (e.g., pure vs. speculative risk), processes (e.g., affective involvement in case) and relations (e.g., trust depending on benefiting from risk) depending on their knowledge, concern, and interests. Finally, we argue that it is important to combine studies on risk perception and risk assessment at an early stage of technology development. The issues and problems of public risk perception are discussed.     

Evaluation of Risk Perception and Risk-Comparison Information Regarding Dietary Radionuclides after the 2011 Fukushima Nuclear Power Plant Accident

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 radiation and smoking risk” enhanced both subjective and objective understanding without diminishing trust in all participants and in the high dread-risk perception group; use of other risk-comparison information could lead the public to overestimate risk.     

How ready are we to move species threatened from climate change? Insights into the assisted colonization debate from Australia

Assisted colonization, the intentional movement of species beyond their native range, has been proposed as a climate change adaptation tool for biodiversity conservation. The risks and benefits of its implementation are still being debated but already the climate is changing, species are moving and the pressure on at‐risk species must therefore be increasing. However, instances where moving species beyond their natural range purely for conservation purposes due to climate change are few, and the opportunity for science to inform practice is limited. Here we survey active participants in flora translocations and/or flora conservation in Australia in order to investigate the gap between theoretical and conceptual ideas about assisted colonization and to gauge preparedness for its implementation. We found that actions that mitigate proximal threats are preferred over those that move species beyond their current range. A lack of knowledge of species biology and ecology is an impediment to the acceptance of assisted colonization. In addition, prohibitive costs and the potential increased risk of the spread of diseases, pests and/or pathogens are viewed as more important obstacles of successful assisted colonization than potential for invasion at the recipient site. Full approval from all stakeholders at the source and recipient sites was found to be the most important factor for the successful assisted colonization of flora.

Communicating the consensus on climate change to college biology majors: The importance of preaching to the choir

College and university biology majors who are not climate change deniers may yet be unaware of the degree of scientific consensus on climate change and unprepared to communicate about climate science to others. This study reports on a population of climate change accepting biology majors at a large, private research university in the American northeast. Our students tended to greatly underestimate the degree of scientific consensus around climate change, to be only moderately worried about climate change, and to be unconfident in their ability to communicate about the state of the scientific consensus around climate change. After an introduction to the scholarly literature that substantiates and quantifies the scientific consensus on climate change in the context of a course on biological research literature, our students showed significant increases in their estimates of the consensus on climate change, and their estimates were more accurate. Additionally, they became more worried about climate change as well as more confident in their ability to communicate about the scientific consensus to others. These results are in line with the Gateway Belief Model, which positions perception of scientific agreement on climate change as an important driver of acceptance and motivation toward action.
