We use conjoint choice questions to investigate people's tastes for cancer risk reductions and income in the context of public programs that would provide for remediation at abandoned industrial contaminated sites. Our survey was self-administered using the computer by persons living in the vicinity of an important contaminated site on the Italian National Priority List. The value of a prevented case of cancer is €2.6 million, but this figure does vary with income, perceived exposure to contaminants, and respondent opinions about priorities that should be pursued by cleanup programs.  相似文献

In the presence of rare disasters, risk perceptions may not always align with actual risks. These perceptions can nevertheless influence an individual's willingness to mitigate risks through activities such as purchasing flood insurance. In a survey of Maryland floodplain residents, we find that stated risk perceptions predict voluntary flood insurance take‐up, while perceptions themselves varied widely among surveyed residents, owing in large part to differences in past flood experience. We use a formal test for overoptimism in risk perceptions and find that, on aggregate, floodplain residents are overly optimistic about flood risks.  相似文献

The persistent gap in flood risk awareness in Canada, and elsewhere in North America, is a continual source of worry for researchers and emergency managers; many people living in at‐risk places are simply unaware of risks and of their proximity to hazards. This study seeks to understand which residents were aware of flood risk, using unique representative survey data of Calgary residents living in the city's flood‐prone neighborhoods collected after the devastating and costly 2013 Southern Alberta Flood. The article uses logistic regression models to analyze which residents were aware of risk to their homes. Findings indicate that, in addition to various demographic predictors, many of the geographic predictors (including the elevation of one's home relative to the river) are significant predictors of awareness. Having a direct sight line to one of Calgary's two rivers is also a significant predictor in some of the models, suggesting that the visibility of hazards matters for flood risk perception, although this effect fades when many of the geographic predictors are added. Finally, the models indicate that several variables related to local, neighborhood‐based social networks are significant as well. These findings reveal that both physical surroundings and social context are important for understanding risk awareness. The article concludes by discussing the relevance for social science research on disasters and hazards, as well as for planners and emergency managers.  相似文献

In the wake of the 2011 Great East Japan Earthquake and tsunami, the Ministry of Environment in Japan asked municipalities nationwide to accept and treat disaster waste. This call for cross‐jurisdictional waste treatment provoked considerable public controversy. To explore how the national and municipal governments can seek more public acceptance in the wake of future disasters, this study implemented a nationwide survey and addressed the question of what factors influence the public's willingness to support their municipalities’ plans to host disaster waste. Three strands of the literature—on risk perception, public dissent, and prosocial behavior—offer valuable insights into hypothesis building, although none has addressed the above question. Estimates from an ordered logistic regression (N = 1,063) reveal that the conditions of a nuclear accident and living with a small child in the household would lower the level of support for accepting disaster waste, although this does not mean that people would give their support in the absence of a nuclear accident. The results also suggest that the national and municipal governments should communicate more with the public about the risks, benefits, and costs associated with hosting disaster debris, and make efforts to improve public trust in the national government.  相似文献

Research indicates that individuals high in belief in a just world (BJW) are confident that they will not fall victim to unforeseeable disasters. The current study tested the hypothesis that BJW acts as buffer that serves to sustain mood and career prospects of those in need of risk protection. Threat was manipulated by confronting participants with risks regarding their career outlook, and individual differences in threat perception were measured by degree of uncertainty tolerance. As hypothesized, BJW helped protect the mood of participants threatened by serious career‐related risks who were unable to tolerate uncertainty. The finding supported the buffer hypothesis regarding mood, but not career prospects, possibly due to a more conscious mindset or variability in self‐efficacy. However, BJW was overall positively associated with career prospects. Moreover, it was suggested that BJW can also serve as a personal resource, not only protecting from risk, but also enhancing mood among those with high uncertainty tolerance.  相似文献

One of the most dynamic and fruitful areas of current health‐related research concerns the various roles of the human microbiome in disease. Evidence is accumulating that interactions between substances in the environment and the microbiome can affect risks of disease, in both beneficial and adverse ways. Although most of the research has concerned the roles of diet and certain pharmaceutical agents, there is increasing interest in the possible roles of environmental chemicals. Chemical risk assessment has, to date, not included consideration of the influence of the microbiome. We suggest that failure to consider the possible roles of the microbiome could lead to significant error in risk assessment results. Our purpose in this commentary is to summarize some of the evidence supporting our hypothesis and to urge the risk assessment community to begin considering and influencing how results from microbiome‐related research could be incorporated into chemical risk assessments. An additional emphasis in our commentary concerns the distinct possibility that research on chemical–microbiome interactions will also reduce some of the significant uncertainties that accompany current risk assessments. Of particular interest is evidence suggesting that the microbiome has an influence on variability in disease risk across populations and (of particular interest to chemical risk) in animal and human responses to chemical exposure. The possible explanatory power of the microbiome regarding sources of variability could reduce what might be the most significant source of uncertainty in chemical risk assessment.  相似文献

The failure to foresee the catastrophic earthquakes, tsunamis, and nuclear accident of 2011 has been perceived by many in Japan as a fundamental shortcoming of modern disaster risk science. Hampered by a variety of cognitive and institutional biases, the conventional disaster risk management planning based on the “known risks” led to the cascading failures of the interlinked disaster risk management (DRM) apparatus. This realization led to a major rethinking in the use of science for policy and the incorporations of lessons learned in the country's new DRM policy. This study reviews publicly available documents on expert committee discussions and scientific articles to identify what continuities and changes have been made in the use of scientific knowledge in Japanese risk management. In general, the prior influence of cognitive bias (e.g., overreliance on documented hazard risks) has been largely recognized, and increased attention is now being paid to the incorporation of less documented but known risks. This has led to upward adjustments in estimated damages from future risks and recognition of the need for further strengthening of DRM policy. At the same time, there remains significant continuity in the way scientific knowledge is perceived to provide sufficient and justifiable grounds for the development and implementation of DRM policy. The emphasis on “evidence‐based policy” in earthquake and tsunami risk reduction measures continues, despite the critical reflections of a group of scientists who advocate for a major rethinking of the country's science‐policy institution respecting the limitations of the current state science.  相似文献

Women's relatively worse performance in negotiation is often cited as an explanation for gender differences in advancement and pay within organizations. We review key findings from the past twenty years of research on gender differences in negotiation. Women do underperform relative to men in negotiation, but only under limited circumstances, which means the performance gap is unlikely due to lesser skills on their part. The barriers between women and negotiation excellence are of three types: cognitive, motivational, and paradigmatic. Cognitive barriers stem from negative stereotypes about women's negotiating abilities. Motivational barriers stem from desire to prevent women negotiators from excelling in a masculine domain. Paradigmatic barriers stem from how negotiation is currently studied. We call for greater attention to motivational barriers and for changes to the negotiation paradigm. Women negotiators are not incompetent, and training them to negotiate more like men is not obviously the solution. In fact, women have greater concern for others than men do, and their cooperativeness elevates collective intelligence and enables ethical behavior. Under a new paradigm of negotiation, the value of these strengths could become more readily apparent. In particular, we advocate for greater attention to long-term relationships, subjective value, and relational capital, all of which may have important economic implications in real world negotiations.  相似文献

The purpose of this paper is two-fold: to reconsider the fundamental role of risk management (RM) in small and medium enterprises (SMEs) by identifying and critically analysing the most important international works; and to define opportunities for further studies by suggesting a different approach to study the topic. This research is based on a new hybrid method developed by the authors, called Advanced, Reasoned and Organised (ARO) literature review, which improves the quality of literature reviews by integrating the systematic review for quantitative papers, the meta-synthesis for qualitative research and the critical interpretative analysis. Forty-eight articles were included in the literature review. Bibliometric and cluster analyses were carried out. Two hypotheses were applied as filters in the interpretative synthesis of the content and guided the analysis to answer two research questions. The findings underline that RM in SMEs is still a ‘spot’ subject as they put little effort into the risk identification, assessment and monitoring. The lack of procedures and strategies is due to the lack of risk mindfulness and knowledge, and it is related to the managers’ and owners’ risk attitudes. It is fundamental to understand why risk procedures are not implemented and to find a way to raise awareness of the potential benefits of risk and control measures. The topic is current, and the multidisciplinary perspective and mixed-method approach enhance both theoretical and practical contributions for academics and SME owners.  相似文献

This paper is a reflection on the UK governments’ latest regulatory intervention affecting all non-financial institutions, including the Office of Nuclear Regulation (ONR). The intervention forms part of the government’s response to the economic downturn experienced in the UK and requires regulators to take into account not only their responsibilities for maintaining safety, but also the impact of their actions on economic growth. While this may be a valid proposition for some organisations, the paper suggests that the unique characteristics of the nuclear industry should exempt its regulator from these government provisions. The paper identifies existing and historic regulatory and governance weaknesses that would suggest regulatory intervention should be reviewed but not from a need to enhance economic growth. Rather a need exists to redesign the regulatory process so that the industry’s hazards and risks arising are mitigated. An inherent conflict of interest is also identified that compounds historic governance problems where publicly-funded, government-appointed regulators attempt to regulate publicly-funded, government-appointed third-party organisations. While in neoliberal terms this may not be seen as an issue, I examine notable, generic, regulatory incidents where managerial and regulatory action failed to resolve resource allocation issues between the need to improve levels of economic growth or safety.  相似文献

The preservation of perishable food via refrigeration in the supply chain is essential to extend shelf life and provide consumers with safe food. However, electricity consumed in refrigeration processes has an economical and an environmental impact. This study focuses on the cold chain of cooked ham, including transport, cold room in supermarket, display cabinet, transport by consumer, and domestic refrigerator, and aims to predict the risk for human health associated with Listeria monocytogenes, the amount of food wasted due to the growth of spoilage bacteria, and the electrical consumption to maintain product temperature through the cold chain. A set of eight intervention actions were tested to evaluate their impact on the three criteria. Results show that the modification of the thermostat of the domestic refrigerator has a high impact on food safety and food waste and a limited impact on the electrical consumption. Inversely, the modification of the airflow rate in the display cabinet has a high impact on electrical consumption and a limited impact on food safety and food waste. A cost–benefit analysis approach and two multicriteria decision analysis methods were used to rank the intervention actions. These three methodologies show that setting the thermostat of the domestic refrigerator to 4 °C presents the best compromise between the three criteria. The impact of decisionmaker preferences (criteria weight) and limitations of these three approaches are discussed. The approaches proposed by this study may be useful in decision making to evaluate global impact of intervention actions in issues involving conflicting outputs.  相似文献

This article investigates potential differences in risk perception between experts (loss-prevention managers in the U.K. oil and gas production industry) and nonexperts (managers and students). Extant research on expert versus nonexpert perceptions of risk is reviewed, followed by the present study concerning risk perceptions of seven pen-picture scenarios involving the occurrence of hazardous events in the U.K. oil and gas production industry. In contrast to many of the earlier studies of expert versus nonexpert perceptions of risk, the present analysis concludes that experts did not judge the overall riskiness of the portrayed hazardous events as less risky than the nonexperts. Nevertheless, the experts believe more strongly than our nonexperts that the risks portrayed in the scenarios pose little threat to future generations, are more precisely known, and are relatively controllable. Use of multiple regression analysis to help uncover the basis of overall riskiness assessments for expert and lay respondents was inconclusive, however. Finally, little evidence was found that nonexperts were any more heterogeneous in their risk perceptions than experts. It may be that the nature of the risks assessed in the present study may account for the general lack of clear expert versus nonexpert differences in overall perceptions of the riskiness of hazardous events in the North Sea. Earlier findings of strong expert versus nonexpert differences in risk perception assessed hazards of major public concern. It is inferred that using such extreme hazards may have resulted in an exaggerated view of differences in expert versus public (nonexpert) perception of risk.  相似文献

While the perceptual nature of corporate reputation is rarely contested, the role of governance and firm financial performance does not have the same consensus. As reputation is an embedded capability that cannot be distinctly valued or traded, the ambiguity in reputation generation clouds researchers’ attempts to understand the relative importance of the underlying causal factors, particularly firm-specific attributes like board characteristics, governance and ownership—independent of the firm’s financial performance over time. Utilizing a resource—based view, we develop a theoretically grounded framework that enables us to deconstruct corporate reputation and parse out the impact at multiple levels and the factors therein. We decompose reputation into time, firm and industry level factors, offer hypotheses on the relative importance of the factors at each level, and thereafter we simultaneously assess within and across the temporal, firm and industry levels to quantify the impact of the causal factors. We find that 49.65 % of the variation in corporate reputation is firm-specific, independent of financial performance, while industry-specific variables account for just 5.04 %. The temporal factors including the multi-level interaction terms explain 46.06 % of reputational variation, of which financial performance accounts for only 18.53 % and the “halo effect” of prior financial performance is short-lived. Furthermore, the commonly accepted factors explain only 26.44 % of the total variation in corporate reputation, and some of the governance and ownership indicators contradict generally accepted agency expectations.  相似文献
